The Vault manages secure user identity and session tokens, ensuring sensitive data is encrypted at rest, stored only in secure locations on the device, and unlocked only with biometric identity (TouchID/FaceID). Always-on Session Management safeguards data even when not using your app, with background screen protection for sensitive data and apps, and automatic logout based on inactivity time.
Identity Vault is built and supported by the Ionic's native mobile experts and includes ongoing updates and maintenance, including new API features, patches, updates, and compatibility upgrades for new iOS & Android releases.
Why Identity Vault?#
Many frontend authentication workflows use unsecure practices like storing tokens unencrypted or using weak authentication logic that is easily compromised. In the past, Ionic developers have resorted to combining third party Cordova plugins, often resulting in insecure setups due to the lack of correct implementation of biometric and at-rest encryption strategies.
Common security mistakes include:
 - Not implementing Apple and Google's mobile security best practices. Guidelines often change with each major operating system release.
 - Combining disparate Cordova plugins together. While the code is open source, it's challenging to know if the latest security best practices are in place, and whether the plugin developer will keep them up to date.
 - Leaking data. Storing tokens unencrypted in localstorage is common but data is easily accessible.
 - Not clearing tokens after user inactivity or when new fingerprints are added. Removing tokens protects users in the event of a lost or stolen device.
 - Displaying data when app is in the background. Highly sensitive data should be protected from shoulder surfing, especially if the mobile app is commonly used in public places.
Identity Vault handles all of the above and more, reducing your team's development time from weeks to minutes while eliminating the need to learn complex native APIs. Instead, they can focus on delivering business critical app features.
How It Works#
Among Identity Vault's many features is the secure management of user identity and session tokens. The Vault ensures sensitive data is encrypted at rest, stored only in secure locations on the device, and unlocked only with biometric identity (TouchID/FaceID). Here's how it works in practice, in a typical authentication workflow.
An app user logs into your mobile app and the backend authentication system verifies their credentials. If valid, the system sends back a session token representing the user's identity and permissions. Since this token represents the ability to make changes on behalf of the user, it's crucial to secure it so that malicious persons or apps cannot access it.
Identity Vault workflow
Your app must store the token somewhere so the user can continue to use it over time, as the token will be sent back to your server to retrieve and modify data at any time. This is where Identity Vault comes in. The token is encrypted and stored at-rest securely on a physical hardware chip - the Secure Enclave on iOS devices. The enclave is isolated from all other system components in order to ensure sensitive user data remains secure.
Later, when an attempt is made to retrieve the user token, the app prompts the user to authenticate using Touch ID or Face ID. After verification, it's permitted to get the token from the Secure Enclave and use it for subsequent data requests.
In addition to secure identity management, Identity Vault fully configurable session management. While in use, the auth tokens will be in-memory of your app, so for an additional layer of protection, the Vault will automatically lock based on the specified inactivity time. It also comes with screen protection, hiding your app's data when put into the background. On iOS, it uses your app's splash screen and the native hide system on Android. Finally, you can use Identity Vault's user service to add the auth token to every backend system request using a HTTP interceptor.

The Cellulo for rehabilitation project aims to provide practical, easy to use and intuitive gamified rehabilitation by using these tangible robots as game agents and objects. Our first game, Pacman for upper arm exercises, is designed iteratively with participation of stroke, brachial plexus and cerebral palsy patients (18 in total) and seven therapists in four different therapy centers.
A number of game elements are designed for tuning speed, accuracy, range of motion and challenge level; these are:
- Different maps with various mazes or sizes,
- One or two ghost(s) robot(s) chasing the Pacman
- Speed of the chasing robot(s)
- Optional rules:
- Turn rule where the user can only collect the fruits by rotating the robot on top of them,
- Cross border penalty rule where the user loses the last eaten fruit when he/she crashes into a wall,
- Haptic feedback rule to provide haptic informative assistance when the user crashes into a wall.

Standing High Jump
This tutorial demonstrates how to use feed-forward control to perform a standing high jump task. It shows how to use different types of functions for feed-forward control, as well as the how to setup the objective function.
Piece-Wise Constant Control
 - Click on File → Open…, and open Tutorials/Tutorial 2a - Standing High Jump.scone
In the editor, you'll see a section called 'Controller', with the following code:
# Controller for the Model
FeedForwardController {
 symmetric = 1
 # Function for feed-forward pattern
 PieceWiseConstant {
 control_points = 2
 control_point_y = 0.3~0.01<0,1> # Initial y value of control points
 control_point_dt = 0.2~0.01<0,1> # initial delta time between control points
The FeedForwardController is the type of controller, and the Function defines the type of function. In this case, we define a PieceWiseConstantFunction function with two control points, and a variable time between control points. The values after control_point_y and control_point_dt define parameters to be optimized, and have the following format:
mean~standard deviation
 - To start the optimization, click on Scenario → Optimize Scenario
If you do not wish to optimize a parameter, for instance if you wish to use a piece-wise function with a fixed time interval of 0.1 seconds, simply change control_point_dt to:
control_point_dt = 0.1 # this parameter is no longer optimized
Polynomial Control
Instead of using a PieceWiseConstantFunction function, it is also possible to use a PieceWiseLinearFunction function or a Polynomial, simply by changing the type of the function.
Keywords in SCONE are case sensitive.
To use a polynomial to define the muscle excitation signal for each muscle, change the code into the following (see also Tutorials/Tutorial 2b - Standing High Jump - Polynomial.scone):
# Controller for the Model
FeedForwardController {
 symmetric = 1
 # 2nd degree polynomial ax^2 + bx + c
 Polynomial {
 degree = 2
 coefficient0 = 0.3~0.01<0,1> # initial value for c
 coefficient1 = 0~0.1<-10,10> # initial value for b
 coefficient2 = 0~0.1<-10,10> # initial value for a
Jumping with a Straight Upper Body
If you have run the optimization for a while, you will notice that the model has a tendency to lean backwards during the jump. The reason for this is that our optimization objective only cares about how high it jumps, not about the pose of its upper body.
The objective function is defined by the Objective and Measure tags. The objective type is a SimulationObjective, which is used for objective functions that are the result of a simulation. Inside the Objective you'll find the Measure that defines the fitness function of the objective.
By default, JumpMeasure measures the maximum height of the Center of Mass (COM) of the model. We can add an additional term to also take into account the orientation of the upper body (see also Tutorial 2c - Standing High Jump - Straight Pose):
# Composite measure for straight pose jumping
CompositeMeasure {
 # Fitness measure for jumping
 JumpMeasure {
 termination_height = 0.75
 prepare_time = 0.2
 # Penalize backwards leaning pose
 DofMeasure {
 dof = pelvis_tilt
 position { min = -45 max = 0 abs_penalty = -10 }
What we've done here is changed the measure type to CompositeMeasure, and combine our JumpMeasure with an additional DofMeasure. The latter applies a penalty when a specific Degree of Freedom (DOF) is outside a specific range. In this case, we define the valid range to be between -45 and 0 degrees, and apply a penalty of -10 per degree at which the pelvis_tilt is outside this range.
Setting the initial parameters
Since we don't want to redo our entire optimization, we jump-start the optimization by initializing the parameters using the result of an earlier optimization. This is accomplished with the following line:
init_file = data/StandingHighJumpFC2.par # use previous result
 - Run the scenario by pressing Ctrl + T
You will notice that the simulation is already jumping, because the parameters from the previous optimization were taken.
 - Start the optimization through Scenario → Optimize Scenario
As you can see, the initial fitness of the optimization is a lot higher than when starting from scratch. As the simulation progresses, you'll see the upper body staying more straight during the jump.
In order to make the optimization run as fast as possible, keep as few optimizations running as possible. Any optimization can be terminated by clicking on the little 'x' in the upper right corner of the optimization window.
Jumping with Knees Up
By default, JumpMeasure tracks the height of the COM of the model. However, it can also be changed to measure the maximum height of a point of a specific body part. For instance, we can measure knee height by inserting the following tag (see Tutorial 2d - Standing High Jump - Knees Up):
body = tibia_r
Note that, since our controller is symmetric, it doesn't matter which side of a body part we choose. In addition to changing the target, we will also add some control points to accommodate for the more complex activation pattern required for this type of jump:
control_points = 4
The init_file will still be used to initialize the first two control points from the earlier jump, but the last two will be optimized from scratch.
 - Start the optimization by pressing ''Ctrl + F5''
After clicking on one of the results, analyze the activation patterns in the Analysis tool, to find out what jumping strategies are found by the optimizer. You might notice that the optimization of this scenario does not progress as fast as the initial one. Apparently, optimizing knee height is more complex than optimizing the COM position!

Test.
Sometimes, a module that has gone through some changes, or has been designed as a drop-in replacement for another module, will have a compatibility interface that mimics another module or another version. These alternate interfaces make it easier to move up to the new module without changing existing code.
However, these additional interfaces can get confusing. They can also preserve older-style constructions and habits, and make it harder to move ahead to well-factored, orthogonal code. Finally, such constructions are often an additional burden on the module maintainer, and may be dropped in future module releases. It's a good idea to update your code to use a module's primary interface.
With longer programs, it's important not to try to make all interface changes at once. Change the interface for a small section, test it, check it into CVS, and repeat. Once you've removed all of the old interface from a file or module, you can change the 'use' statement to avoid importing the functions that you no longer need. Make sure that you run tests afterwards.
CGI is a good example. The CGI module has a compatibility interface with the old routines which make it easier to start using CGI in old code. Once you've updated to CGI, you can go through the code and update the interface in small steps. Once you think you've eliminated all of the code using the old ReadParse/%in interface, you can remove the ':cgi-lib' from the 'use CGI' declaration. Testing the code after that will tell you whether you've gotten rid of all of the old calls.
Change If/Then to Hash Lookup
Condition: You have a series of if/then/elsif statements mapping one set of values to another
Resolution: Build a hash table mapping the two sets of values, and turn the set of if/thens to a subroutine lookup.
if ( $fruit eq 'lemon' ) { $color = 'yellow'; } elsif ( $fruit eq 'orange' ) { $color = 'orange'; } elsif ( $fruit eq 'tomato' ) { $color ='red'; }
changes to:
our %Fruit_Colors = ( lemon => 'yellow', orange => 'orange', tomato =>'red', ); $color = $Fruit_Colors{$color};
 1. Build hash mapping conditionals to values.
 2. Replace conditional statements with hash lookup.
 3. Test.
Frequently, programmers moving to Perl from other languages will have to map one value to another. Unused to the power of Perl's hashes, they will build huge chains of if/then statements-- if $foo is 'doogie', set $bar to 'howzer', or if $foo is'michael', set $bar to 'knight', etc. These huge clusters are impenetrable to the eye. Plus, if at any time you need to alter these values, you need to go spelunking into lightless code-caverns, searching for just the right conditional.
The idiomatic Perl solution is to use hashes any time one is mapping one set of values to another set of values. With a hash, it's easy to see what maps to what. Even better, you can put the hash at the top of your file, where it's easy to find and alter without messing around deep inside the code.
Build a table. Start at the top of your conditional block and add one line similar to michael => "knight" for each conditional. Then you can replace the conditional block with a simple hash lookup.

The team's lab setup was used to test the powerplant condenser system. The mesh is placed above the funnel at right to collect the water that condenses on the mesh. (Courtesy of the researchers)
BOB HIRSHON (host):
Fresh water from power plants. I'm Bob Hirshon and this is Science Update.
US power plants use up 39% of the country's freshwater supply to cool down hot pipes, and much of it evaporates and is lost. This according to MIT engineer Kripa Varanasi and his colleagues, writing in Science Advances. They've developed a technique that electrifies water droplets so they can be collected on an ionized mesh and recycled before they escape out the smokestack.
KRIPA VARANASI (MIT):
They actually make a U-turn and get collected on the mesh.
He says the technology could conserve precious water supplies. And in arid coastal areas where power plants use seawater for cooling, the technology could be particularly useful: Varanasi explains that evaporating seawater results in freshwater vapor, which the nets can capture to produce a new source of drinking water. I'm Bob Hirshon, for AAAS, the science society.

In 2003 it was forecasted that medical students'preclinical learning would mostly consist of large portions of educational training and instruction provided on the internet and other technology tools, while the traditional lecture format would become more infrequent. Five years later many medical schools have adapted to this new technological-enhanced learning environment.
No one can argue that today's millennial generation of medical students is more familiar with technology than their predecessors. However, does this technology savvy generation report that these new tools are indeed superior when compared to the traditional tools of facilitating learning and understanding in the preclinical years? Additionally, is there a difference in usefulness of learning techniques for students in year one as compared to year two of medical school?
This study examines the learning tools in basic science courses to determine how the millennial generation of students report they are learning best. Tools from our blended learning curriculum were investigated within and across preclinical years one and two.
Presented at the AAMC (Association of American Colleges) Annual Meeting, RIME (Research in Medical Education) Program, November 2008.


text: The objective of Spreadsheet Query is to provide the user with two powerful tools for the strategic and competitive analysis of a nation in terms of the Millenium Development Goals. The first tool is called the Reference Matrix. The Reference Matrix creates a bubble chart that compares a Country's results with respect to a group of indicators against the results of the other countries within the same geographical region, income level or type of lending. The second tool is called the Goals Scorecards. The Goals Scorecard allows the user to follow up on a Country's performance with respect to the Millenium Development Goals, through a graphic representation of their deviations or progress achieved. Spreadsheet Query is an Excel (Microsoft Office) based application. It works with Excel 2003 and higher versions. It takes advantage of the functionality offered by these spreadsheets for the management and analysis of databases.

Matte Painting: winter
This is my second matte painting tutorial (first tutorial here).
Here I wanted to change the season of a scene from summer to winter.
Specific device used: Wacom Intuos² A4
Alright, first let's modify the colors.
Using Image > Adjust > Hue / Saturation, try to get softer colors with less contrasts and saturation. Make it look cold!
Create a new layer
Now we can begin painting the snow. Use a rough brush to create irregular shapes. In the tools window, set the foreground color to pure white, and the background color to a blue-tinted white which will be used to add shadows on the snow.
All steps involve working alternatively with these two colors.
Begin by adding snow on the edges of the house where the snow would naturally fall onto.
With the blueish white, paint the inferior part of the snow (the shadows). This will add depth and will simulate the way snow reacts to light.
Create a new layer
With the same brush and same white, paint the windows to give them a frosted look. Set this layer's transfer mode to Overlay to make it match.
Create a new layer
Same principle, on the roof this time.
Make sure you stay true to the original lighting. Parts where the sun directly hits the roof should be a lot brighter than the darker spots, which will blueish. This is important especially on the cone shaped parts.
When everything will be painted, you can then use the Blur tool and make a smooth transition between pure white and blueish white. After that, use the Burn and Dodge tools to increase or decrease contrasts. If you use Burn on the blue-tinted whites, it will give you an ice look, which can be interesting.
Create a new layer
Now we are going to paint the ground. I used an irregular brush so that the grass wasn't entirely covered. Then using the blueish color I added nuances to simulate an undulating look. I also left a clean way that goes to the door.
Same principle to add snow applies to the trees and bushes in the garden.
Now let's do something to avoid boredom from only adding snow!
Using the Dodge tool, on the house layer, brighten spots here and there to add frosted parts, as well as to lighten up the dark parts of the house (like the inside of the porch). Do not forget that snow is a reflective surface, it will bounce light off pretty much everywhere.
Using the same method, brighten up the rest of the scene like the trees and sky.
Subtle, but necessary since it adds the important detail that sells the overall effect and makes the image look natural.
Create a new layer
Now on to the extremely boring step : powder snow over the trees. Powder is subtle, so don't overdo it!
Still using the same method, add snow accumulations on branches, the most difficult part being to actually see where those branches are. It depends on the quality of your picture.
If you have chosen a picture without trees you are a cheater!!
For the big branches in the foreground, we can see leaves. I chose to add snow on groups of leaves, which can be time consuming, but you should not choose the shortest way over quality work.
Create a new adjustment layer : Brightness/Contrast
This step is optional, but I created a layer and have applied a linear gradient from top to bottom to increase the contrast at the bottom of the pic.
Here it is!
You can compare the original image and the matte painting!

Different types of computer security cables are typically categorized either by the way in which they can be connected to a computer system or by the type of lock used on them. Cables for desktop computers and similar components might simply fit through loops and other areas on the components to keep them secure. Some cables, however, can be directly connected to a computer, either through a particular slot on the computer or through a laptop connection. Many computer security cables also come with locks as part of the cable, and these can include both keyed locks and combination locks.
Computer security cables are lengths of cable, usually steel cables that cannot easily be cut, which are used to fasten computer components and devices to a larger object such as a desk or cart. Cables for use with desktop computers can often be run through clips connected to the computer and to the desk to ensure a strong hold. These clips may be fastened onto computer devices using powerful adhesive that forms a nearly permanent bond, while metal fasteners can be physically installed onto a desk or cart. Such computer security cables usually end in loops to make fastening them to such systems easier.
Ad
There are also computer security cables designed to connect directly to different pieces of hardware and computer equipment through an electronic connector. Some cables, for example, can be used to lock a monitor directly to a computer system through the use of a monitor cable that includes a lock while allowing a signal to be transmitted to a monitor. Laptops are also commonly connected to a cart or desk through these types of computer security cables. Many laptops are designed with a security slot that is part of the body of the laptop, and cables can be connected directly to these slots for a more secure connection.
Computer security cables can also be categorized based on the types of locks used on them, regardless of how they can connect to different pieces of equipment. Keyed locks are quite common, and these cables usually come with two keys that can be kept by maintenance or security professionals at a business. These are usually small cylinder locks and keys, though some cables with loops may work with standard padlocks. There are also some computer security cables that have a built-in combination lock that can be used, which prevents the lock from being disengaged without the right combination of numbers selected.

Effect of tree leaf N status and N application time on yield and fruit N partitioning of mango
Nitrogen (N) is an essential nutrient in mango (Mangifera indica L.), but research on N fertilizer uptake and partitioning in mango is lacking. The objective of this study was to determine the influence of timing of N fertilizer application on yield and N allocation in leaves and fruits on mango trees ('Kensington Pride') with variable leaf N dry matter concentrations. Nitrogen was applied (200 g tree-1) using 15N-labelled urea (2.1 atom% excess 15N) either at postharvest or pre-flowering on trees with low (1.0%N) and high (1.2%N) leaf N status. Results showed that %N derived from fertilizer (%Ndff) was greater in high-leaf-N trees when N was applied during postharvest, but did not differ significantly when applied at pre-flowering. Leaf N status of mango trees and timing of N application had no marked influence on total number of fruits, total fruit weight, or weight of fruit. However, yield efficiency (total fruit yield divided by trunk cross-sectional area) in trees with high leaf N status was higher than those trees with low leaf N status, yet did not differ for timing of N application. Total N uptake was higher in the flesh of the fruit from low-N trees than in high-leaf-N trees. The %Ndff did not differ in the skin, flesh or seed of mango. However, %Ndff was significantly higher in fruits from trees with low leaf N status and when N was applied at pre-flowering. Results indicate that N allocation in the leaves and mango fruit differ depending on leaf N status of trees and timing of N application.

{\mathcal{C}}$, and $h$ with a natural transformation of functors $H: F \rightarrow F'$. Since every vertex of $\operatorname{Sing}_{\bullet }(X)$ is contained in $K$, this natural transformation carries each point $x \in X$ to the identity morphism $\operatorname{id}_{ \overline{f}(x) }: F(x) \rightarrow F(x) = F'(x)$. It follows that the functors $F$ and $F'$ are identical, so that the morphisms $\overline{f}$ and $\overline{f}'$ are the same. $\square$
Proof of Theorem 3.4.7.1. For every group $G$, let us write $BG$ for the groupoid having a single object with automorphism group $G$ (Example 1.2.4.3). Fix a point $x \in U \cap V$. To show that the diagram
\[ \xymatrix@R =50pt@C=50pt{ \pi _{1}( U \cap V, x) \ar [r] \ar [d] & \pi _{1}(U,x) \ar [d] \\ \pi _{1}(V,x) \ar [r] & \pi _{1}(X,x) } \]
is a pushout square in the category of groups, it will suffice to show that the diagram $\sigma _0$:
\[ \xymatrix@R =50pt@C=50pt{ B \pi _{1}( U \cap V, x) \ar [r] \ar [d] & B \pi _{1}(U,x) \ar [d] \\ B\pi _{1}(V,x) \ar [r] & B \pi _{1}(X,x) } \]
is a pushout square in the (ordinary) category $\operatorname{Cat}$.
For each point $y \in X$, choose a continuous path $p_{y}: [0,1] \rightarrow X$ satisfying $p(0) = x$ and $p(1) = y$. By virtue of our assumption that $U$, $V$, and $U \cap V$ are path connected, we can arrange that these paths satisfy the following requirements:
 - If $y = x$, then $p_ y: [0,1] \rightarrow X$ is the constant map taking the value $x$.
 - If $y$ is contained in the intersection $U \cap V$, then the path $p_{y}$ factors through $U \cap V$.
 - If $y$ is contained in $U$, then the path $p_{y}$ factors through $U$.
 - If $y$ is contained in $V$, then the path $p_{y}$ factors through $V$.
Note that, for $W \in \{ X, U, V, U \cap V \} $, we can identify $B \pi _{1}(W,x)$ with the full subcategory of $\pi _{\leq 1}(W)$ spanned by the point $x$. Let $r_{W}: \pi _{\leq 1}(W) \rightarrow B \pi _{1}(W,x)$ be the functor which carries each point of $W$ to the point $x$, and each morphism $\alpha \in \operatorname{Hom}_{\pi _{\leq 1}(W)}( y, z )$ to the composition $[p_{z}]^{-1} \circ \alpha \circ [p_{y}]$ (where $[p_ y]$ and $[p_ z]$ denote the homotopy classes of the paths $p_ y$ and $p_ z$, regarded as morphisms in the fundamental groupoid $\pi _{\leq 1}(W)$). The functors $r_{W}$ restrict to the identity on $B \pi _{1}(W,x)$ and are compatible as $W$ varies, and therefore exhibit $\sigma _0$ as a retract of the diagram $\sigma :$
\[ \xymatrix@R =50pt@C=50pt{ \pi _{\leq 1}(U \cap V) \ar [r] \ar [d] & \pi _{\leq 1}(U) \ar [d] \\ \pi _{\leq 1}(V) \ar [r] & \pi _{\leq 1}(X) } \]
in the category $\operatorname{Fun}( [1] \times [1], \operatorname{Cat})$. Since $\sigma $ is a pushout square (by virtue of Theorem 3.4.7.2), it follows that $\sigma _0$ is also a pushout square. $\square$
If $X$ is a topological space and $U \subseteq X$ is a subspace (not necessarily open), we will write $\mathrm{H}_{\ast }(X,U; \operatorname{\mathbf{Z}})$ for the relative homology groups of the pair $(X,U)$: that is, the homology groups of the quotient chain complex $\mathrm{C}_{\ast }(X; \operatorname{\mathbf{Z}}) / \mathrm{C}_{\ast }(U;\operatorname{\mathbf{Z}})$ (see Example 2.5.5.3).
Theorem 3.4.7.3 (Excision for Homology). Let $X$ be a topological space and let $U,V \subseteq X$ be subsets whose interiors $\mathring {U} \subseteq U$ and $\mathring {V} \subseteq V$ comprise an open covering of $X$. Then the inclusion $U \hookrightarrow X$ induces an isomorphism of relative homology groups
\[ \mathrm{H}_{\ast }( U, U \cap V; \operatorname{\mathbf{Z}}) \rightarrow \mathrm{H}_{\ast }(X, V; \operatorname{\mathbf{Z}}). \]
Proof. Let $K$ denote the pushout $\operatorname{Sing}_{\bullet }(U) \coprod _{ \operatorname{Sing}_{\bullet }(U \cap V) } \operatorname{Sing}_{\bullet }(V)$. We then have a commutative diagram of short exact sequences of chain complexes
\[ \xymatrix@R =50pt@C=40pt{ 0 \ar [r] & \mathrm{C}_{\ast }(V; \operatorname{\mathbf{Z}}) \ar@ {=}[d] \ar [r] & \mathrm{C}_{\ast }(K; \operatorname{\mathbf{Z}}) \ar [r] \ar [d]^{\theta '} & \mathrm{C}_{\ast }(U;\operatorname{\mathbf{Z}}) / \mathrm{C}_{\ast }(U \cap V;\operatorname{\mathbf{Z}}) \ar [d]^{\theta } \ar [r] & 0 \\ 0 \ar [r] & \mathrm{C}_{\ast }(V; \operatorname{\mathbf{Z}}) \ar [r] & \mathrm{C}_{\ast }(X; \operatorname{\mathbf{Z}}) \ar [r] & \mathrm{C}_{\ast }(X; \operatorname{\mathbf{Z}}) / \mathrm{C}_{\ast }(V; \operatorname{\mathbf{Z}}) \ar [r] & 0. } \]
Consequently, to show that $\theta $ is a quasi-isomorphism, it will suffice to show that $\theta '$ is a quasi-isomorphism (Remark 2.5.1.7). This is a special case of Proposition 3.1.6.18, since the inclusion $K \hookrightarrow \operatorname{Sing}_{\bullet }(X)$ is

DO-178C is the international and de facto standard for certifying all aviation safety-critical software.
The purpose of DO-178C is to provide guidance for developing airborne software systems to ensure that it performs its intended function with a level of confidence commiserate with its airworthiness requirement.
DO-178C is objective driven and companies may use a variety of means to achieve compliance as long as they meet the objectives in question. To comply with DO-178C, companies must provide multiple supporting documents and records surrounding their development processes.
Different airworthiness levels within DO-178C—A, B, C, D and E—directly correspond to the consequences of a potential software failure: catastrophic, hazardous/severe-major, major, minor or no effect, respectively.
Each software level has a defined number of objectives that need to be satisfied (some with independence). Objectives requiring independence need documentary evidence that the person verifying the item is not be the person who developed the item.
These different software level certifications also determine the rigor required in testing and other aspects of development—the most challenging of which is software verification.
DO-178C compliance involves six key processes: planning, development, verification, configuration management, quality assurance (QA) and certification liaison.
One of the significant changes in DO-178C from DO-178B is that there are four additional supplements that may be used in conjunction with the DO-178C.
The Federal Aviation Administration (FAA)EASA and Transport Canada approve all commercial software-based aerospace systems. Through DO-178C these certification authorities emphasize that achieving compliance needs to be done in all aspects of development.
Want to learn more about DO-178C? Tonex offers DO-178C Training, a 3-day course where participants learn about the compliance aspects of DO-178C and comprehend the objectives of DO-178C as the primary means for meeting airworthiness requirements to obtain approval of software used in civil aviation products.

The Zoo's three olive baboon babies are now 16 months old and have started to develop some great talents! Because of their constant curiosity and motivation, the baboon babies have learned how to paint and partake in the University of Rochester cognitive research study.
So how do you teach a baboon to paint? Cheerios were placed underneath the door frame, shown in the picture to the right, behind a dot of paint. In order to get to the Cheerio, the baboons had to reach under the door frame and pull towards them. Every time they "finger painted," a Cheerio was given as a reward. Once this concept was figured out, getting paint on them and everywhere else was fun!
Baby baboon Pico de Limon, shown in the picture to the left, was the first baby to join the study with the University of Rochester that many of our adult baboons have been working on for the last two years. He is progressing very quickly, learning that choosing the cup that held the most peanuts meant that he got to eat them! In just a few weeks, he now has three cups placed on the board and has been able to choose successfully that three peanuts going into one cup is more than one peanut going into another.
We are very excited to see what level his counting skills are at compared to the adults as well as getting some insight as to what age these skills start to develop.

Dart: How to remove leading spaces in a multiline string (using splitMapJoin)
As far as I know, there's no built-in way to remove spaces from a multiline string in Dart, but you can write your own Dart function to do this.
For example, I just dug into the splitMapJoin method of the Dart String class, and wrote a stripMargin function like this:
String stripMargin(String s) {
 return s.splitMapJoin(
 RegExp(r'^', multiLine: true),
 onMatch: (_) => '\n',
 onNonMatch: (n) => n.trim(),
 );
}
Now, given a multiline string like this:
final s = '''
 four score
 and seven
 years ago
 ''';
When you print it like this:
print(stripMargin(s));
you'll get this left-trimmed multiline output:
four score
and seven
years ago
I haven't tested that beyond this example, but if you need a way to left-trim a Dart multiline string — i.e., to remove the leading spaces from a multiline string — I hope this function is helpful.
P.S. — The name stripMargin comes from a method of the same name on Scala multiline strings.

ABSTRACT Objective: This study proposed to investigate whether magnesium sulfate (MgSO4) could reduce the ovarian damage induced by cyclophosphamide (Cyc). Material and Methods: Thirty female rats were used for this study: Control group (n=10)- Only laparotomy; Cyc group n=10)-75 mg/kg Cyc intraperitoneally; and Cyc+MgSO4 group (n=10)-75 mg/kg Cyc on day 0 and 200 mg/kg MgSO4 on days 1-7 (both intraperitoneally). The extent of histopathological damage and the number of ovarian follicles were determined. The levels of anti-Mullerian hormone (AMH) were measured in blood samples. Results: Statistically significant differences in the AMH values were observed in the control group versus Cyc group and Cyc group versus Cyc+MgSO4 group (p<0.05). The levels of AMH were the least in the Cyc group. The total tissue damage in the Cyc group was significantly higher than that in the control, as well as in the Cyc+MgSO4 group (p<0.05). The follicle counts were the least in the Cyc group. Conclusion: Cyc caused ovarian damage and reduced the ovarian reserves. The ovarian reserves in the MgSO4-treated group were better than those in the other groups, and there was least ovarian damage in the MgSO4-treated group.

While in the Three Sisters Wilderness Area, you decided to try some surveying with the aid of a protractor and a piece of string, as in the figure above. The rock keeps the string pointing straight down, and the straight edge of the protractor can be lined up with an object, allowing you to measure its angle of elevation. When you use this setup to look at something that is at the same elevation you are, the string intersects the mark on the protractor.
First, you lined up the protractor with South Sister, and it read. Then you walked 1 km toward the mountain, lined the protractor up again, and it read. What did you measure South Sister's relative elevation to be, and how far from the mountain were you when you made the second measurement?


Side 5
 - by
Side 5 Loum was a space colony cluster located in front of the moon at Lagrangian Point L4 that belonged to the Earth Federation.
The cluster shared the Lagrangian Point with Side 2.
Side 5 was a colony cluster at Lagrangian Point L4. It witnessed the Battle of Loum that saw massive damage to the colonies, vessels and mobile suits. The resulting debris formed a shoal zone around the region.
 - Texas
 - Industrial 7
 - Watohoat
The Texas colony was privately owned by the Yashima Group, led by Shu Yashima. It was the only remaining colony after the Battle of Loum. It was designed for agricultural purposes but the reflector mirrors malfunctioned due to the battle and the colony was abandoned.
Industrial 7
Industrial 7 was a closed-type colony owned by Anaheim Electronics. Half of the two million population on the colony were Anaheim staff and their families. The factory and harbour segments faced the Earth while the colony builder unit Rokuro faced the moon.
Side 5 was one of the first places to be attacked by the Principality of Zeon at the start of the One Year War.
Operation British
After Zeon forces successfully executed Operation British by dropping Side 2 Colony 8 Island Iffish on Earth, Zeon forces attempted to seize colony Watohoat from Side 5 to drop on the Earth Federation capital Lhasa.
Federation General Revil's 1st Combined Fleet intercepted the Zeon Space Attack Force commanded by Dolze Zabi. Both sides engaged in indiscriminate use of nuclear, biological and chemical weapons to bring a quick end to the war. Watohoat was completely destroyed.
Battle of Loum
The Battle of Loum caused the deaths of 3 billion people in the first week of war from 3 January to 10 January, later known as the One Week Battle.
Debris of colonies, vessels, and mobile suits from the battle led to the formation of a shoal zone around Side 5.
In UC 0090, a battle between anti-Federation group Colorde and the Federation's Arahas force broke out in the Texas colony.
In UC 0218, the Federation collapsed and Side 5 became a member of CONSENT.


Southern Blind SnakeScientific name: Anilios australis
Meaning of name: The meaning of Anilios is not known. Australis is Latin meaning southern.
Distribution: Occurs throughout the southwest of Western Australia from north of Geraldton to near the South Australian border.
Description: The body colour can be from a purplish-brown to purplish-grey to pink with a cream belly. They can grow to 42cm long.
Notes: This is the most common blind snake in Perth. They shelter beneath rocks, stumps, logs and rubbish. They eat only ants and termites, meaning they are harmless to humans. Blind snakes use an unpleasant odour produced from their anal glands to deter predators.

If you're a guinea pig owner, chances are you've heard that having a guinea pig in your home can help keep spiders away. But is this true? Here's what you need to know about using guinea pigs as a spider repellent.
Do guinea pigs keep spiders away?
While guinea pigs may keep spiders away from their cages, it's not a guaranteed solution for an entire home.
Spiders enter like any other insect through small cracks and crevices in the wall or windows. And considering guinea pigs are relatively tiny animals and require special care within the home, they can't patrol all the nooks and crannies that spiders might find inviting.
On top of keeping clean, sealing off entryways with weatherstripping is critical to spider prevention.
Ultimately guinea pigs make great house pets, but when it comes to spiders in your home, unfortunately, they won't be much help.
How Guinea Pigs Might Help Keep Spiders Away
The idea behind using guinea pigs as spider repellent is that the smell of the pet will keep spiders away from your home.
While there is no scientific evidence to support this claim, the smell of a guinea pig may be enough to deter some species of spiders or at least make them less likely to stay in your house for an extended period.
However, several other factors could contribute to fewer spiders in your home, even if you have a guinea pig.
For example, if you keep your home clean and free from clutter—which is always recommended when owning any pet—you may have fewer spiders than before.
Additionally, certain types of plants (such as lavender or citrus) may help repel spiders naturally, without the need for any pets in the house.
Is it Safe to Have Both Guinea Pigs and Spiders Around?
If you still find yourself with spiders and guinea pigs in your home, don't worry too much about their safety.
Guinea pigs should not be able to come into contact with any dangerous spider species as they can cause severe harm or illness if bitten.
However, spider webs may pose a choking hazard for guinea pigs, so it's essential to ensure that all webs are regularly removed from around their cage space.
Are spiders a danger to guinea pigs?
Guinea pigs are particularly vulnerable to spiders since they are small mammals and cannot defend themselves against the bite of the more dangerous species.
One of the biggest threats comes from domestic house spiders, who can build intricate webs and weave into enclosures.
These webs will capture any insects that come close and, if left alone, can cause severe distress to your guinea pig.
To reduce the likelihood of this happening, vacuum all surrounding areas regularly and clear out any webs you spot before they cause harm.
Additionally, don't let wild spiders into your house, as it risks introducing danger to your guinea pig.
Prevention is critical when taking measures against spiders becoming a hazard for your pet – take it seriously, and you should be able to avoid blundered encounters with eight-legged creatures.
How to get rid of spiders without harming the guinea pigs?
Keeping your guinea pig safe is paramount, so if you have an issue with spiders, getting rid of them can be challenging without endangering your pet.
Luckily some great methods will allow you to eliminate the eight-legged invaders safely and effectively.
Vacuuming regularly helps remove spiders and their webs, especially when upholstered furniture is involved.
Opening the windows to bring in more natural light also helps, as spiders do not like bright areas.
Applying cedar oil or vinegar around your windowsills, doorways, the perimeter of your home, and any other dark area will repel them from emerging.
Finally, use limited chemical sprays only on spot treatment; keep your guinea pigs away from sprayed areas until completely dry. With any luck, these tips will help keep your guinea pig free from harm and spider danger.
While having a guinea pig may help reduce the number of spiders in your home by deterring them with its scent, it isn't guaranteed to work every time. So be sure to keep up with regular cleaning habits and consider adding some natural spider-repellent plants near windowsills.
Most importantly, be sure that your furry friend cannot come into contact with any potentially dangerous spider species, as this can put their health at risk.

Dr. Amman Bolia is a pioneer in Interventional Radiology specializing in peripheral vascular disease. In 1987 he developed a technique to treat critical limb ischemia called Subintimal Angioplasty. His technique doesn't require many materials or the use of very expensive medical devices, is relatively simple to execute and works well. Yet for the first ten years Dr. Bolia found it difficult to convince his peers to transition to this new technique. Convinced that this technique could efficiently and without undue costs alleviate the pain that these patients suffer from, Dr. Bolia pushed on. Today, the Subintimal Angioplasty technique has stood the test of time and is considered one of the most useful, efficient and cost effective methods for the treatment of critical limb ischemia.
"I believe in medicine that works simply and efficiently and is readily available to both the practitioner and the patient. And I'm driven to find medical techniques and devices that make this possible."Dr. Bolia currently serves as a Consultant Radiologist for the University Hospitals of Leicester NHS Trust in Leicester, United Kingdom. He has been nominated for the prestigious Pioneers in Performance Award by the Cardiovascular and Interventional Radiological Society of Europe.
Dr. Bolia is currently working with Merit Medical on ideas to continue to advance peripheral intervention.

Jim Bachman, Tobias Gummersbach and John Loughrey of GR-NEAM, offer a 'top-down observable price' approach to benchmarking.
Regulators have legislative responsibility to establish solvency standards for insurers. Rating agencies have a commercial interest in providing a framework to gauge insurers' capital adequacy. For each the focus is to assign capital charges to the various activities of insurers, tally their accumulation and conclude the need for regulatory intervention or assigning a financial rating, respectively.
Two developments give us pause to review capital charges of different regulatory and rating agency regimes. The first is the creation of the US Federal Insurance Office. The second is EIOPA's most recent publication addressing underlying assumptions of the Solvency II Standard Model Formula (SII).
The focus of this article is the investment capital charges developed within the SII and, in particular, contrasted to the charges developed using GR-NEAM's 'top-down observable price' methodology. We highlight these differences using the security level holdings of the US property/casualty (P/C) industry.

How long do skateboards last? When should I replace it?
How long do skateboards last is a common question among skateboarders these days. This article is for you if you'd like to know the answer and tips for maximizing your skateboard's lifespan.
While it is not an easy query to address, the typical lifetime of a skateboard is about two years. In reality, it is mostly determined by several important factors, including the skateboard's manufacturer, efficiency, use, and maintenance.
In this article, I'll go through all causes that influence the lifespan of a skateboard, as well as what you should know to enable your skateboard to last longer.

Factors impacting skateboard's life?
 - Always double-check if the wheels are properly tightened. If this isn't the case, use the skate tool to tighten or loosen the skateboard nut in the truck.
 - Be familiar with all of the stunts and tricks associated with skateboarding. If you don't know the fundamentals, don't take all of these seriously.
 - One of the most important factors is skate style. Beginners usually destroy their skateboards easily since they are unfamiliar with the sport.
 - Skating on rails and ledges would easily break down the skateboard because it impacts the skateboard more than usual.
 - Weight is a significant concern. The skateboard is more likely to break down quickly if you are overweight.
 - Many people get irritated and throw the skateboard when they are unable to ride properly. If you don't want your skateboard to crack early and quickly, never do it and try to control yourself.
 - Skateboard durability – Obviously, the higher the quality and robustness of your skateboard, the longer it will last. Skateboards with high quality often cost more money and last longer than inexpensive skateboards, so bear that in mind as well.

The lifespan of a skateboard varies based on the type of rider
While I mentioned that a skateboard will last around two years, this is only true for average riders. If you want to see how long your skateboard could last, figure out if you're a Daily Rider, Amateur or Professional.
To decide how long does a skateboard last, you must first consider the three styles of skateboard riders and then define which group you belong to.
The daily skateboarder
The daily rider is a skateboarder who only rides from home to work or college, and there are many skateboarders who just ride for fun from a certain location to another location that they favor every day.
Unlike the amateur rider who frequently does stunts and rides with friends, these riders just go out with friends and do stunts on occasion. Regular users should expect skateboards to last at least two to four years, based on where they ride and how they use them.
The amateur skateboarder
The amateur rider is primarily a rider who does not ride day after day, but at least three or four days per week in skateboard-friendly places.
The skateboard of an amateur rider can last at least 6 months to 2 years, and if you maintain it well and just ride occasionally, it can last much longer.
The pro skateboarder
Pro skateboarders are riders who compete in skateboarding events, ride for hours on skateboards, and practice tricks and stunts and nearly every day in order to improve.
Skilled skateboarders damage their boards more rapidly. I know many professionals who adjust their boards monthly since they perform extreme tricks that lead their boards to break down more quickly.
They would like to pay extra for new skateboards. For example, if the manufacturers do not advance the wheels to make them more suitable for skateboarding, they would just substitute them.

How to make your skateboard last longer
Here are good tips to take care of your board so that it can last as long as possible.
Skateboards should be well-maintained.
Your skateboard, like other devices, requires your attention and should be maintained daily. If you ignore it and leave dirt to accumulate on the skateboard for a long time, the effect is irreversible, and you'll have to purchase a new board soon.
Even novice skateboard cleaners will find cleaning a board to be quite quick and easy. To prevent tearing, you should sand the skateboard's sides regularly.
Sanding the edges would keep them clean and protect them from chipping. To remove the wheels from the board's axle, use a skate tool.
Remove the wheel bearings. Brush and rinse them after soaking them.
Using grease, lubricate bearings to clean the trucks and wheels.
The wheels should be immersed in the washing liquid for a short period to soften grime and dirt. However, the rest of the skate should not be.
If it's raining, don't ride your skateboard.
Water damages not just your deck, but also your trucks, bearings, and wheels. When the deck wood gets wet, it becomes soft and quickly breaks or slits apart.
Protect the board from rain and, if it does get wet, dry it quickly with an air dryer. Do not clean the board by dipping it in water because it can cause a lot of damage to the board. To clean the deck, wipe it off with a towel.
how long should a skateboard last
Don't ride your skateboard in the rain
Don't do any stunts or tricks that aren't appropriate for your ability.
Many beginner riders underestimate the difficulty of doing stunts and tricks that are inappropriate for their skill level.
Doing tricks that are not relevant to your skill level is extremely dangerous. It increases your chances of splitting your skateboard into two pieces, especially if you are a beginner rider.
Rather than attempting stunts and tricks that are inappropriate for your skill level, begin with the fundamentals and gradually progress to a more challenging and critical level. This would make you better on the skateboard and reduce the chances of breaking the skateboard.
Riding on sand, glass and stone is not recommended.
Skateboard wheels can be ruined if you ride on sand or glass, and if the skateboard crashes to the ground when standing on rough surfaces, it will be severely damaged.
And if it doesn't crack, it would quickly lose its efficacy. and it will not last for long. So, find a flat road or a designated skate park where you can skateboard smoothly and learn all sorts of tricks.
Avoid slipping on the skateboard's tail.
Many skateboarders like sliding or stopping on the tail, which not just rubs the tail against the surface but may also smash the board after a few tries. So, don't slip on the skateboard's tail because the tail is the most fragile component of the board.
Avoid leaving the skateboard in your car
Many skateboarders make the big mistake of simply leaving skateboards in the car, assuming that keeping their skateboard in a car would be far more reliable than keeping it in a cold place.
However, if you leave your skateboard in the car, the heat will be much higher, which can affect your board, including the trigger and wheels, because these components are heat sensitive.
The issue with a car is that it absorbs the maximum amount of heat while driving in the sun, particularly if the car is black; it will damage your skateboard more seriously.
Shoes Matter
Wearing the best skate shoes can extend the life of your skateboard. When skating, never purchase or wear low-quality shoes. It can put a strain on both your legs and your skateboard. You'll likely get wounded as well if you wear the wrong shoes.
Land skateboard properly
Skateboarding depends solely on landing. If you don't know how to land properly, your skateboard would most likely break down quickly. At the very least, you must try to land on your skateboard with one foot.
Try landing on both feet after you've learned to land with one foot. Every day, practise, practise, practise. Eventually, you'll be able to land on two feet.
Store the skateboard
Many riders who purchase a skate are not even thinking where to place it. There are many skateboarding racks available on the market. They are reliable and do not take up much space.
Furthermore, you do not have to worry about anyone accidentally trampling or damaging your skate. Moisture, cold and heat are rivals of this board. As a result, streets, basement, and car are not suitable places to store it.
I hope that your concern on "how long do skateboards last" has been answered in this article. Riding a skateboard is such a great activity, plus it is inexpensive and enjoyable. The production, repair, use, and quality of a skateboard all affect its lifespan.
If skaters want their boards to last for years, they should only use them on flat and dry surfaces. And after a long trip, remember to clean and lubricate your skateboard to maintain it.
Finally, suppose you want your skateboard to last longer. In that case, I recommend that you practice the fundamentals of skateboarding, advance slowly with the tricks, and purchase the best branded skateboard possible. Best of luck!

I've read article about WorkManager _URL_ and I have the question. In order to use Workmanager, I vae to create that object using admin console and during creating workmanager I can set some properties like thread priority or pool size. In that article we can see java example:
InitialContext ctx = new InitialContext();
WorkManager wm = (WorkManager)ctx.lookup("java:comp/env/wm/default");
ThreadFactory tf = new WASThreadFactory(wm);
BlockingQueue q = new ArrayBlockingQueue(10);
ThreadPoolExecutor pool = new ThreadPoolExecutor(
1, 10, 5000, TimeUnit.MILLISECONDS, q, tf);
My question is, what happen after putting new values to ThreadPoolExecutor constructor? Is it possible to overwrite WorkManager properties defined in Websphere by that code? What is dependence between values passed to constructor and values defined for Workmanager in websphere using admin console?

Types of Agriculture in Japan 日本の農業の種類
1.What are the different types of agriculture in Japan?
What kind of work do you think of agriculture? You may have a strong image of just growing rice and vegetables. In reality, there is a wide range of work included under the term agriculture.
In the "Japan Standard Industrial Classification (revised in October 2013)" established by the Ministry of Internal Affairs and Communications, agriculture is classified into five categories: "Establishments engaged in administrative or ancillary economic activities," "Crop farming," "Livestock farming," "Agricultural services, except gardening services," and "Gardening services.
However, in general, it is often divided into three types: "crop farming,", "livestock farming," and "agriculture-related business."
This article will look at the specific contents of these three types of agriculture.
2.What is "Crop Farming"?
Crop farming is the cultivation of rice, other grains, vegetables, fruit trees, flowers and other plants, etc. The work environment varies greatly depending on the scale of farm and type of crop.
The work of large-scale farms often involves the use of agricultural machinery. Smaller farms or those in environments where agricultural machinery is not available may work mainly by hand.
Furthermore, in open-field or greenhouse cultivation, workers have to work with exposure to the outside temperature, which would be hard in the hot summer months. On the other hand, in a plant factory, workers may work in an environment where the temperature and humidity are artificially controlled.
3.What is "Livestock farming"?
Livestock farming refers to raising, fattening, and incubating livestock and poultry, such as cattle, pigs, chickens, horses, sheep, and ducks. Typical examples are dairy farming, beef cattle production, and poultry farming.
Dairy farming is the production of milk. It may also involve selling cheese and ice cream, which are processed products of milk, or operating as a tourist farm.
Beef cattle production is the job of raising cattle for beef. Recently, the development and production of regional branded beef has become a hot topic. There are two types of farms: breeding farms, where mothers raise calves for a certain period of time, and fattening farms, where calves are bought at a market and are raised to a large size, although some farmers carry out both processes in an integrated manner.
Poultry farming is into two categories: egg production and meat production. Poultry farming in Japan is becoming increasingly modern and large-scale, and, commonly, a single farmer often manages tens of thousands of chickens.
4.What is "Agriculture-related business"?
Agribusiness is a general term for a wide range of industries related to agriculture. It is sometimes referred to as agribusiness, a term coined by combining the words agriculture and business.
Agribusiness mainly involves working to support people engaged in crop farming and livestock farming and connecting producers with consumers.
For example, one of agribusinesses activities is developing a distribution system to sell both agricultural products and processed products directly to consumers. In addition, there has been much attention in recent years on the use of robots, ICT, and other technologies in agriculture to save labor and improve quality control for producers.
As mentioned above, there is a wide range of work related to agriculture in Japan.

Quanex has released a new product, the SolarGain Edge Sealant, which is a rubberized sealant for PV modules to protect against degradation due to moisture. The Edge Sealant is a polyisobutylene butyl rubber adhesive with integrated desiccant that has been designed to improve longevity, durability, and power retention over time.
Quanex said the sealant can prevent moisture ingress in modules, while also protecting cells, connections, and conductive coatings. The company said it can delay loss of power over a module's lifetime by significantly delaying any degradation mechanisms activated by moisture, and that it can extend the useful life of a module by 10 to 15 years.
Quanex said emerging trends in the PV module market are driving the importance of moisture sealing. New technologies like perovskite solar cells and heterojunction (HTJ) cells have shown higher module efficiency, but they have also shown greater moisture sensitivity.
While it is commonly assumed that crystalline silicon panels are not sensitive to moisture ingress over the long term, recent testing by the company has shown SolarGain Edge Sealant's ability to provide high levels of moisture protection in c-Si panels, extending lifetime power output.
Traditional ethylene vinyl acetate (EVA) encapsulants have the potential to generate acid that can sap a panel of its power, due to the corrosiveness of the acid when exposed to moisture over time. Alternative encapsulants like thermoplastic polyolefin (TPO) and polyvinyl butyral (PVB) have demonstrated higher potential to resist moisture ingress versus EVA, but are considerably more expensive and difficult to handle during the assembly process.
The sealant product is backed by Quanex's 50 years of experience. Its various solutions demonstrate many of the same attributes required in solar module sealants, including UV resistance, flexibility through a wide range of temperatures, and the ability to delay the migration of moisture.

Of course, the debate is not new. But have the two sides of the argument really heard each other?
Many see Piet as a harmless tradition, associated with fond memories of childhood and family. Yet an increasing number of people throughout the Netherlands question Piet's history as tied to historical forms of entertainment that mocked the appearance and character of black people. So where exactly does the tradition come from? And what, if anything, does it have to do with practices of blackface and minstrelsy in other parts of the world? And why should any of it matter to a traditional Dutch person seeking to celebrate Sinterklaas as it has been done for more than 100 years?
John Helsloot (folklore historian from the Meertens Institute) will provide the historical background of Zwarte Piet's origins as Sinterklaas' servant and his rise to popularity. Then both sides of the pro vs. anti-Piet discussion will be represented in a moderated discussion, followed by audience comments.

Official Name: Sharyland Independent School District
Motto: "Commitment, Cooperation and Communication"
Colors: Red and White
Communities Served: Sharyland, Mission, Alton, Palmhust, Edinburg, and McAllen
Brief History: Sharyland is a large community in the Lower Rio Grande Valley situated between the cities of Mission and McAllen. Before the 19th century, the area where Sharyland now stands was sparsely populated with ranching families, most of Mexican descent. However, by the late 19thcentury and early 20thcentury "Anglo" land developers took an interest in many of the lands along the Rio Grande. One such developer was John H. Shary, a native of Nebraska who visited the Rio Grande Valley in 1912. Shary saw the potential for farming and citrus production and within a short time purchased thousands of acres of land which he named Sharyland. Sharyland attracted farmers from the North and Midwest and became known for its citrus production. Sharyland was also John Shary's home until his death in 1945.
Sharyland Independent School District is named in honor of John H. Shary who was president of the district's first board of trustees. Created in 1921, this twenty-six square-mile school district is located in Hidalgo County. The district is committed to providing the highest quality education possible for all students.
Public schools in Sharyland include: Jessie L. Jensen Elementary School, John H. Shary Elementary School, Lloyd and Dolly Bentsen Elementary School, Olivero Garza Sr. Elementary School, Romulo D. Martinez Elementary School, Ruben Hinojosa Elementary School, Donna Wernecke Elementary, Harry Shimotsu Elementary, BL Gray Junior High School, Sharyland North Junior High School, and Sharyland High School.

I got my hair cut in the morning. This is an example of the causative form. Causative verbs are used to talk about getting something done by somebody else. Some common expressions using the causative verb forms are given below.
- You must have your hair washed. / You must get your hair cut.
- You must get that carpet cleaned.
- You must get / have your nails polished.
- We must have the roof repaired.
In this structure we use the past participle form of the verb.
- We must have the house painted. (NOT We must have the house painting.) (NOT We must have the house paint.)
Causative forms are also possible with make. Causative forms of make often imply the idea that somebody has a certain authority over somebody else.

In celebration of World Wetlands Day, which is observed on 2 February, the City of Tshwane is happy to announce that it has taken the first steps in rehabilitating the Centurion Lake and Hennops River.
On 5 February 2020, the City will remove the remaining two sluice gates of the Centurion Lake Weir at the Hendrik Verwoerd Bridge, which will increase the free flow of water through the lake, and get the drainage and desilting process of the lake underway.
While this signals the end of an era of a major Centurion landmark, the lake was not constructed in such a way that it could deal with the extent of pollution and accumulated sediment from upstream municipalities. Over the past decade, more than 50 000 m3 of sediment has accumulated in the lake and opening the weirs will relieve the pressure on the existing storm water systems flowing into the lake. It will also reduce leakages from the sewage system on the southern side of the lake, and reduce odours from stagnant water.
Once the weirs have been opened, the City will start removing silt from the northern and southern stretches of the lake, as well as the silted area in front of the Centurion Hotel. This will create channels on either side of the lake, improve the water flow and speed through the lake, and eventually improve storm water drainage.
The City is constantly interacting with the National Department of Water Affairs and Sanitation to ensure that all processes are in accordance with the City's water use licence. The rehabilitation process will have a minimal downstream impact, however, residents downstream will notice a darkening of the water colour for the first few weeks. As the water levels in the lake drop, exposed sediment may release unpleasant odours, which will improve as the sediment dries out.
As part of the lake rehabilitation process, much consideration has been given to preventive upstream measures, such as minor excavations of silt at the ARC Weir. The City is also planning to construct a sediment and litter trap at the weir. This will significantly reduce the amount of silt and litter being flushed downstream. The entire project will require the cooperation of our neighbouring municipalities as well as the National Department of Water Affairs and Sanitation.
The City will continue to work with all spheres of government and the non-governmental organisation sector to find sustainable solutions for a cleaner, safer Hennops River.

Finger Dowsing: How To Tell If Your Partner Is Faithful – by Tana Hoy
Did you know that you can use a secret psychic method of divination to tell if your partner is faithful? You don't have to use a pendulum, or other psychic tools such as Tarot cards to get this information. All you need is your mind, your will, and your index finger, to get an answer!
Finger Dowsing - An Excellent Method To Find Answers
To dowse is when you try to search for hidden objects, like water or treasures, with the use of instruments such as pendulums and dowsing rods. When you dowse with your finger, your finger becomes like a human dowsing rod. Instead of lusing it to look for objects, you can use it to find answers to questions, especially questions about love and relationships.
Learning to dowse with your finger is actually very convenient because you can do it very discreetly. For example, while you're sitting across from your date in a restaurant, waiting for your food to be served, you can secretly divine an answer to find out if he or she is really interested in having a relationship with you. Or when you are standing in line behind your partner, you can use it to see if they are being faithful, or telling the truth about something!
How To Be A Finger Dowser
Certain preparation is needed if you're going to use this finger technique to dowse, especially when it's your first time. But the most important advice I can give is, always try clear your mind of jealousy, vengeful thoughts, self-doubt, and other negative emotions, when using this method, as this will greatly affect the answer you will get.
Here are the steps you need to do to prepare yourself for using this method:
1. Every day for several days, spend time in a quiet room.
2. Focus your attention on the tip of your index finger – if you're right-handed, use your left index finger, and if you're left-handed, use your right one.
3. Visualize in your mind that the tip of your finger is like an antenna for receiving psychic energy. Imagine it becoming hyper sensitive to the energy of your surroundings.
4. Be clear in your mind that your index finger is for receiving vibrations, not sending them out, because you don't want to accidentally zap someone with your focused energy.
5. Point it at different objects in the room, and try to sense their energy through your finger.
How To Calibrate Your Finger
After a few minutes of doing this, you will need to calibrate your finger:
1. First, point your index finger at nothing in particular, and hold it steady for a few moments, and then start moving it up and down. Affirm in youe mind that this up and down movement means "yes." Keep practicing this until you feel comfortable associating this finger movement with a "yes" answer.
2. Next, point your finger steadily forward again, and move it from side to side, allowing yourself to accept that this means "no." Repeat this until you feel comfortable knowing that this is a "no" answer!
3. Now, point your finger steadily forward again but this time move it in a circular finger movement. Program your mind to know that this means "uncertain."
Now, practice asking yes or no questions that you know the answer to. For example, point your finger at the lamp and ask yourself, "Is the lamp turned on?", etc. See if you can get a response.
You will need to practice this exercise several times a day, whenever possible. Don't fret if you don't get a response right away. It takes lots of practice and patience.
Once you're confident of your ability at getting answers using finger dowsing, you are ready to use this technique to answer your question about your partner.
How To Finger Dowse
- Before you meet your partner, spend some time meditating. You need to clear your mind of negative emotions, and be as relaxed as possible.
- As you meditate, focus your mind on this person. Try to see him or her objectively – as a person. Imperfect, yet perfect in his or her own right.
- After a while, form the question you want to ask. Remember, it has to be answerable by yes or no, and it needs to be objective so your personal emotions won't influence the outcome.
- Ask your question several times inside your mind. Then let it go.
- Relax your mind for another few minutes, then slowly bring yourself out of your meditative state.
Finger Dowsing is really simple to do!
1. Look for an opportunity where you can discreetly use your finger dowsing. You can do it under the table, or while you're watching a movie. Just make sure that you do it discreetly, since no one enjoys being pointed at.
2. Point your finger discreetly at your partner.
3. Ask your question inside your head.
4. Wait for your finger to give you an answer.
Now, remember, if you get an answer you don't particularly like, it's not good manners to start a fight or storm out. It's always best to talk it over, and settle the score.
If you want to know if someone is faithful, or confirm what you suspect, during a psychic reading I can give you the right advice and show you how to handle this situation! You can schedule a psychic reading with me by clicking here now!


Take the 2-minute tour ×
I have an array of objects, some of which respond to :description, and I want to get the description from the first one with a truthy description. I could do this:
objects.detect{|o| o.try(:description)}.description
or this:
objects.map{|o| o.try(:description)}.detect{|o| o}
but the first isn't DRY (description is in there twice) and the second iterates through the whole array before finding the value. Is there anything in the ruby standard library, or in Rails' extensions to it, which would let me do something like this:
objects.detect_and_return{|o| o.try(:description)}
I know I could write it easily enough, but the standard libraries are big enough that I might not need to. Is there a function which works like my detect_and_return?

Is there a functional programming term for this (apart from lazy evaluation)? – Andrew Grimm Aug 14 '11 at 23:29

I haven't seen such a method, and the closest I found was a method capture_first which I found in the gem merb-cache. Seems they stumbled on the same problem and implemented this:
module Enumerable
 def capture_first
 each do |o|
 return yield(o) || next
You could also take a look at the Array and Enumerable methods in the Ruby facets library and see if you find something similar. Facets contains quite a lot of goodies, so you might get lucky.

Indeed - Enumerable#find_yield, aka Enumerable#map_detect. Thanks - I'd not heard about facets before. – Simon Aug 3 '11 at 13:45

Originally trained in sculpture and drawing Wendy Miller is a Sydney based multidisciplinary artist working across video, installation, objects, and mixed media. Unconfined by constraints of a single medium, her work investigates themes of ruin, disintegration and disorder. Paper for fragility, clay for disintegration or fabric for decadence, Miller selects materials that specifically encapsulate her aim in order to create works in which form and concept intrinsically coalesce.
In this way, Miller explores the current state of the Anthropocene; the irreversible impact of the human on the planet. Her work is a delicate tribute to botanicals with sinister undertones. She contrasts the beauty and intricacy of plants with a sense of darkness and devastation to shine a light on the irreversible acts of extinction and human destruction. Flora is portrayed as an incredibly charged subject matter that therefore enables her to explore contemporary themes of beauty, wonder and delicacy alongside themes of capitalism, colonialism and ecological ruin. The visual, olfactory and sensual nature of flora provides the theatre that slows the viewer to contemplate these larger issues.
Miller similarly draws on the theme of ruin to introspectively comment on the damage wreaked by colonialism. She examines the role her colonial ancestors played in the frontier wars that resulted in the near genocide of Tasmanian Aboriginals. Flora is used as a symbol of these atrocities throughout her work. In addressing these colonial histories Miller highlights the continuing global impact on contemporary society.

Soybeans are one of the cheapest sources of protein and are very essential for the nourishment of both adults and children. Soybeans farming is very easy to establish and does well in most soils in Nigeria. We want to take a look at how to grow Soybeans in tropical regions like Nigeria, Ghana, Kenya, Ivory Coast, and others. But before then, let's look at the benefit and profit potential in soybeans farming.
Benefits of Soybeans Farming
Apart from human consumption, soybeans are used for the production of nutritious animal feeds of different kinds in the market. Approximately 98 per cent of the soybean meal that is crushed is further processed into animal feed with the balance used to make soy flour and proteins. Of the oil fraction, 95 per cent is consumed as edible oil; the rest is used for industrial products such as fatty acids, soaps and biodiesel.
Why is soybean so useful? Soybean is one of the few plants that provide complete protein as it contains all eight amino acids essential for human health. Soybeans contain the highest amount of protein that can be found in any legume or grain. They also contain a decent amount of carbohydrates, fat, dietary fibre, minerals, and vitamins. It is equally used for the treatment of many chronic diseases.
Soybean is indeed the powerhouse of goodies and cultivating it means cultivating good food and powerful medication for humans and animals. No one who engages in such farming can escape smiling home with wealth.
Soybean is one of the products you can export and make dollars but unfortunately, Nigeria is not yet exporting this valuable product despite being the highest producer of this crop in Africa. The reason is that we are not yet producing enough. The world market for soya is about $42 billion and Nigeria is currently producing soya worth $86 million. Can you see the gap now?
If a farmer could take it to the next level and begin to farm this product in a very large quantity, he would have enough to export and make foreign currency from the over $40-billion global annual market. Even if you decide to sell locally, there is a huge market for it in Nigeria too. Many products in the market are being made with soybeans such as soya milk and soya vegetable oil.
The price of soybeans in Nigeria per metric tonne is about N100,000. If you produce 20 metric tonnes in a season, you will be making N2,000,000. You can produce 20 metric tonnes of soybeans in Nigeria with N700,000. That means in a season you will be making N1.3 million naira from the modest investment of N700,000!


text: The basic requirement for the successful deployment of a mobile augmented reality application is a reliable tracking system with high accuracy. Recently, a helmet-based inside-out tracking system which meets this demand has been proposed for self-localization in buildings. To realize an augmented reality application based on this tracking system, a display has to be added for visualization purposes. Therefore, the relative pose of this visualization platform with respect to the helmet has to be tracked. In the case of hand-held visualization platforms like smartphones or tablets, this can be achieved by means of image-based tracking methods like marker-based or model-based tracking. In this paper, we present two marker-based methods for tracking the relative pose between the helmet-based tracking system and a tablet-based visualization system. Both methods were implemented and comparatively evaluated in terms of tracking accuracy. Our results show that mobile inside-out tracking systems without integrated displays can easily be supplemented with a hand-held tablet as visualization device for augmented reality purposes.

Detailed DescriptionA color base is a container of color elements.
The most common use of color base is in the implementation of a pixel, in which case the color elements are channel values. The color base concept, however, can be used in other scenarios. For example, a planar pixel has channels that are not contiguous in memory. Its reference is a proxy class that uses a color base whose elements are channel references. Its iterator uses a color base whose elements are channel iterators.

Indian born Fanny Maxwell, named for her Scottish aunt Frances Maxwell, married Lieut. John Tritton at Cawnpore on 1 November, 1821. This marriage united two families who had settled in Cawnpore at the beginning of the 19th century and whose descendants laid the foundations of the modern industrialized city now known as Kanpur. Fanny was born on 19th April, 1803 at Aleabad in the province of Oude, daughter of John Maxwell (_PHONE_) and great granddaughter of Reverend John Lumsden (_PHONE_), Professor of Divinity at King's College, Aberdeen and a Moderator of the Church of Scotland. John Maxwell's father was Minister at Newmachar near Aberdeen and his early death had left John, his seven sisters and their mother Agnes (nee Lumsden) penniless. Some of the Lumsden cousins had prospered in India and in 1786 John Maxwell arrived in Calcutta where he ran a library, edited the India Gazette and was partner in the firm of Davidson and Maxwell, which sold European goods, and sent shipments up the Ganges on 1st and 15th of each month. John Maxwell, with an Indian bibi, fathered two children in Calcutta – Agnes born in 1790 who died in infancy and Adam born in 1793.
About 1800 John Maxwell settled in Aleabad where Fanny was born to an Indian bibi and where John Maxwell established himself as an indigo, cotton and sugarcane planter on the banks of the Ganges. A few years later John Maxwell moved to nearby Cawnpore where he had the concession distilling and supplying rum to the British troops stationed in the vast Cawnpore cantonment. John Maxwell had four more sons in Cawnpore with a common law wife Elizabeth Nann. They were Peter (_PHONE_), Hugh (_PHONE_), David (_PHONE_) and James (_PHONE_). These boys, like their brother Adam, were sent back to Aberdeen to the care of John Maxwell's sisters and for their education at Aberdeen Grammar School where their uncle Andrew Dun was rector. Fanny, beloved by her father, lived in the beautiful Maxwell family home in Cawnpore until the age of twelve, when she was sent to London to the care of Mrs. Currie where she improved her English, learned music, dancing and English refinements. A letter dated 4th November, 1816 from John Maxwell to his daughter Fanny in London is full of love and wise advice (reproduced by Zoe Yalland in her book – Traders and Nabobs: The British in Cawnpore _PHONE_). However, when Fanny received this letter her father was dead. John Maxwell died on 27th December, 1816 and was buried in Kacheri cemetery in Cawnpore. Fanny was in London, the younger brothers in Aberdeen and Adam was the only one of John Maxwell's children to attend the funeral.
Adam had returned to Cawnpore in 1811 accompanied by his cousin Alexander Burnett (_PHONE_) and these two young men worked in the Maxwell enterprises. However John Maxwell left a complicated estate and five years elapsed before his will was settled. In 1819 John Tritton's regiment – 11th Light Dragoons arrived in Cawnpore and Fanny's cousin Thomas Lumsden (_PHONE_) was in Cawnpore staying in the Maxwell home. Thomas Lumsden wrote a book Journey from Meerut in India to London in the years 1819 and 1820 – and he described the glittering social scene "all the beauty and fashion of the station".
One of these beauties was Fanny Maxwell who married John Tritton in 1821 with her brother Adam as a witness. A dispute developed between Adam Maxwell and Alexander Burnett and Adam left Cawnpore around 1822 to live in Aberdeen. Adam later moved to London where he met and married Harriet Ann Vandenbergh, sister of my great, great grandfather, on 20th February 1827 at St. Mary Islington. Newly married, Adam heard that Alexander Burnett had taken his own life, and the Maxwell fortune was lost. Adam and Harriet returned to Cawnpore where the problems were compounded because Adam was regarded as an Anglo Indian and while he could own the land on which huge taxes were due he could not inherit from his father's estate. Adam was later accused of fraud, fined, sentenced to prison and died in 1838.
Fanny was also an Anglo Indian but she had a northern mother with lighter skin and she had already inherited one sixth of her father's estate. With her inheritance Fanny was able to live a comfortable life in India with visits to London and Scotland and her husband's military career prospered. Fanny and John Tritton had four sons and four daughters. Their youngest son, Nicholas Burnett died in Perth, Scotland on 2nd January,1841 at the age of three and two sons had army careers – Robert Burnett (_PHONE_) and Edmund Spry (_PHONE_).
Fanny and John Tritton's first child, John Maxwell Tritton born 25th July 1822 joined the East India Company as an administrator. In 1852 he was appointed assistant to the political agent in Bhopal, Assistant Magistrate and Deputy Collector and later served in Nimar. Kumaor, and Gurhwal. However on 26th May, 1859 he left the Civil Service and joined his uncle Hugh Maxwell in establishing the Elgin Cotton Spinning and Weaving Company of Cawnpore. John Maxwell Tritton died in Cawnpore on 1st January 1868.
Fanny's husband John Tritton had risen to the rank of Lieut. Colonel by the time he retired from the army on 13th December 1853. He had fought with distinction in some of the fiercest and bloodiest battles of the sub-continent but a civilian accident claimed his life. The incident was reported in Friend of India of January 1854 –"On their way to Bombay, a distressing accident occurred to Colonel and Mrs. Tritton. Their carriage fell over the bridge on the Panwell Road. Colonel Tritton's arm was broken and Mrs. Tritton was seriously injured". The accident proved fatal for John Tritton and less than a month later, on 8th February 1854, he died and was buried in Bombay cemetery. Fanny recovered and settled in London. She outlived her sons but she had daughters in London and a brother David in Scotland. Fanny maintained a constant correspondence with the children of her brother Hugh in Cawnpore, sending gifts and advising on their weddings. Her brother Peter and his bibi, a Kashmiri lady, had died in the Cawnpore massacre of 1857. Fanny died on 14thJune, 1874 at Orsett Terrace, Paddington, London. She left a large fortune to be administered by her brother David Maxwell.
