On Saturday a number of families gathered in Foresta 2000 woodland in Mellieħa to celebrate the school donations raised for tree management in the area. Donations were collected through a fundraising activity of Dinja Waħda, the environmental education programme run by BirdLife Malta.
"The school donations are vital in helping to look after the developing trees so that future generations will be able to enjoy walking through rich woodland, full of healthy local trees and shrubs," Ray Vella, Foresta 2000 reserve warden said.
Last scholastic year a total of €4,378 was raised. The school which raised the most money was Rabat Primary School which collected an impressive €360 by involving the whole school.
This accumulates from 20 euro cents that children donate for the Dinja Waħda activity called Foster a Forest. Each time a donation is made, they colour a part of a paper tree, thus making the tree grow. This activity also teaches about the importance of forests as ecosystems and homes for wildlife.
BirdLife Malta organised Foresta Family Day, a new annual event, to thank all of the kids, parents and teachers. On Foresta Family Day participants enjoyed a guided walk and other activities such as tree planting demonstration, a discovery session to find out the variety of plants and animals, and time for creativity with nature art.
"My favourite part was naming a tree and getting to know about them," said Ellen, one of the participating kids.
The Dinja Waħda programme currently covers over 80% of all Primary Schools, providing educators with vast teaching resources for environmental education.
Foresta 2000 is a restored wooded area, where to date over 21,000 native trees and shrubs have been planted in the formerly degraded land.

Getting the current joint angles for the PR2
Description: This tutorial shows you how to get the current joint angles for the PR2 robot.
Keywords: joint angles display joint_states mechanism state
Tutorial Level: BEGINNER
Overview
In this tutorial, we will show you how to get the current joint angles for the PR2 robot (arm, head, torso, etc.) from within a ROS node, using sensor_msgs/JointState messages.
Before you begin, bring up a robot, either on the hardware or in gazebo.
The joint_states message
The current positions and angles for the robot are by default being broadcast on a message topic called joint_states, of type sensor_msgs/JointState. This message contains arrays of joint names (string[] name), along with the corresponding positions (float64[] position), velocities (float64[] velocity), and efforts (float64[] effort). If you type
rostopic echo joint_states
at the command line after a real or simulated robot has been launched, you can see these messages as they are published.
A handy server
If you happen to want to filter out only a few joint angles and obtain their joint values, you might want to write a server such as this one.
The node we present in this tutorial listens to and keeps track of the most recent joint_states message, and offers a service that returns the current position, velocity, and effort for any set of desired joint names.
The first thing we'll need to do is create a package. To do this we'll use the handy roscreate-pkg command where we want to create the package directory:
roscreate-pkg joint_states_listener rospy sensor_msgs
After this is done we'll need to roscd to the package we created, since we'll be using it as our workspace.
roscd joint_states_listener
Creating the service message
Now we need to define a service message that we can use to ask for specific joint angles, velocities, and efforts. Put the following into srv/ReturnJointStates.srv:
string[] name
---
uint32[] found
float64[] position
float64[] velocity
float64[] effort
Now uncomment the line
rosbuild_gensrv()
in your CMakeLists.txt and type make in the joint_states_listener directory to generate the service message files.
Creating the service node
Put the following into nodes/joint_states_listener.py:
 1 #!/usr/bin/env python
 2 #spins off a thread to listen for joint_states messages
 3 #and provides the same information (or subsets of) as a service

Addressing Barriers to DEI in Clinical Research
Breaking down barriers to participation in clinical research has long been a challenge, affecting every aspect of the industry. As the industry works toward a more cohesive, diverse, and inclusive environment for all, Advarra's mission is to invest in understanding and educating the industry on this critical topic. Developing a more inclusive and equitable study and research environment will reap many benefits for the industry and establishes the precedent for future trials as we work toward a more inclusive environment for all.
However, figuring out where to address barriers and create a more inclusive environment is overwhelming. This blog aims to define diversity, equity, and inclusion (DEI), discuss exclusive trends in recruitment and trial design, and present actionable steps sites can take immediately.
When researchers address the lack of diversity in clinical research and work to improve upon it in their current practice, a common mistake made is not understanding the nuances of DEI efforts, and looking at each concept as a separate entity, rather than understanding how they intertwine. While DEI is made up of individual concepts, every concept is needed to support one another, and it's common for researchers to focus on one or two concepts, rather than all three simultaneously. To further understand how to achieve DEI in research, each concept needs to be defined as such:
- Diversity: making sure everyone is represented
- Equity: being fair to anyone involved
- Inclusion: creating an appropriate environment for all involved
Many researchers attempt to solve the symptoms of the problem, when in reality, addressing the root cause – which is most often tied to a lack of equity – will allow research staff to address and work toward solving DEI-related challenges the industry faces today.
Effectively Recruiting Participants
Throughout the industry, recruitment proves to be a major roadblock at any stage of a protocol. Without the necessary amount of participants enrolled in any study, startup delays, ultimately costing researchers time and money. Each protocol must have appropriate inclusion and exclusion criteria; however, researchers still focus on populations most convenient to them and do not evaluate criteria critically for each study. This practice enables researchers to seek out populations they are familiar working with and neglects certain populations because of criteria denying them participation in a trial.
Actionable Steps to Take
Since racism is not individual, it must be addressed at a systemic and structural level. If researchers want to solve recruitment problems for their studies, they need to look at the system as a whole and improve and build upon the current infrastructure. If teams are unsure where to start, these common barriers may be the first place to look at and examine.
Communication is paramount for success, including the clinical research industry. If researchers are not effectively communicating their trials to seek out participants, whether that is through physicians, community leaders, or other forms of advertising, then they will lose out on obtaining a diverse participant population.
An easy way to ensure better communication is to create an action plan moving forward. Build workflows into patient visits so potential participants know there are trials available to them. Understand how staff communicates to participants during visits – both online and in person. Are researchers meeting their participants where they're at in terms of the language they can understand? Are participants coming in for necessary visits, and participating in remote capabilities as well? Consider these as the action plan is formulated and built.
Oftentimes, people will choose to participate in a trial if they know they can trust the process. Building relationships with external stakeholders, such as community leaders, their own providers, or word-of-mouth referrals benefits everyone. It gives researchers an opportunity to spread awareness about a trial, it gives stakeholders the opportunity to help others seek treatment, and it helps potential participants feel reassured if it's coming from a trusted source.
Building trust isn't something research teams should rely on with just external stakeholders; trust needs to be maintained after a participant agrees to take part in the trial. For example, including a diverse staff team who may have a better understanding of participants' backgrounds, allowing them to advocate for them. This effort will greatly aid in establishing trust, recruiting potential participants, and retaining them as the protocol moves throughout each phase.
Effectively Design a Trial
Many times, staff get into the "copy/paste" habit when designing a trial. This is normally done in an attempt to save time by transferring the same requirements from one protocol to the next, especially when dictating the trial's inclusion and exclusion criteria. This method is a direct symptom of a staff's heavy bandwidth, but in reality, every trial needs to be designed individually as each trial is unique from the rest.
Additionally, as humans design trials, we need to acknowledge our own implicit biases at work when creating one. As a trial is shaped, taking extra time to review and understand where an individual's biases may have impacted the design can greatly minimize the risk of creating a non-inclusive trial. As we work together to create a more inclusive and equitable research environment, it's important to understand this process will require intentional and continual learning and unlearning from everyone involved.

Hyper BL-algebras
Xiao Long Xin, Xiao Long Xin, Yu Xi Zou, Jian Ming Zhan
Abstract
We put forth the concept of hyper $BL$-algebras which is a generalization of $BL$-algebras. We give some non-trivial examples and properties of hyper $BL$-algebras. Moreover, we introduce weak filters and weak deductive systems of hyper $BL$-algebras and study the relationships between them. Then we state and prove some theorems about weak filters and weak deductive systems. In particular, we define the concept of regular compatible congruence on hyper $BL$-algebras and construct the quotient structure in hyper $BL-$algebras. Finally, we discuss the conditions in which a quotient hyper $BL$-algebra is an $MV$-algebra.

Definition - What does Seta mean?
Seta is a term that describes the morphology of plants. It is typically used in regards to moss. Mosses are also known as sporophytes. It stem or stalk that supports the stalk that supports the capsule.
MaximumYield explains Seta
When it matures, the seat will usually rapidly elongate, and it brings the capsule to the suitable height for dispersing spores. The seat will have vascular tissue, and it enables the sporophyte capsule to get nutrients from the parent.
Another definition for the term seta is a nerve-like extension to a leaf. It can also mean a bristle or a stiff hair.

May 1, 2000 - Form Cancellation

Form Cancellation
Tips: May 2000
Yehuda Shiran, Ph.D.
Doc JavaScript
A form can be submitted via the Enter key when it consists of only one text field, and the cursor is currently located in that field. Sometimes, we want to force an action by the Enter key, without submitting the form. The trick is to use the onSubmit event handler, do the required action when the trigger goes off, and then cancel the event by returning a false value. In this way, we still utilize the advantages of the submit button (submission via the Enter key) without actually submitting the form.
Let's take an example. Suppose a form's header is defined as:
<FORM NAME="organizer", onSubmit="display(); return false;">
and is composed of two elements:
NAME="prefix"
 - A submit button,
 - VALUE="Display"
 The user can submit the form by clicking the button labeled "Display," or by pressing Enter when the cursor is located in the text field. When the user submits the form, the onSubmit event handler is triggered. It invokes the display() function.
 The onSubmit event handler returns false in order to cancel the form's submission. If we aren't really submitting the form, then why didn't we use a standard button instead of a submit button? The answer is simple. If we used a standard button to invoke display() via its onClick event handler, that would be the only way to call display(). By using the form's onSubmit event handler to call the function, the user can also load the desired page by pressing Enter within the text field.

On the new Huntebrücke in Diepholz, a dynamic lighting concept ensures that the light automatically adapts to the use of the bridge and at the same time becomes a landmark for the city. In the month of June - the month in which the twinning between Diepholz and Thouars was signed - the bridge appears in the colors of the tricolor of Germany and France as well as the coats of arms of Diepholz and Thouars.
In other months, for example, the play of colors between the beach and the sun, snowfall or spring meadows appear in dynamic light images that make the bridge appear different again and again.
However, as soon as pedestrians or cyclists approach the bridge, their path across the bridge is always illuminated in white light in accordance with the current specifications of DIN EN13201. In the approach area to the bridge, the correct route is made visible via projections from GOBO spotlights. This white light also appears again and again in different movements on the bridge and makes entering the bridge a surprising experience again and again.


How to Easily Resize Window In Gnome [Quick Tips]
How do you usually resize a window? Move your mouse pointer to the corner of the window and click to resize it, simple, right? Well, if you are using Gnome (Linux), resizing an application window can be a hit or miss affair. In some applications (such as Nautilus), the corners width are huge and you can easily click and drag to resize them. However, in other applications, the sidebar and corner width is only a pixel wide and moving your mouse cursor to that exact point (where the cursor become the resize arrowhead) can be a tedious task.
Here are some ways you can use to make resizing the window an easier, and enjoyable task.
1. Alt + Middle click
At anywhere in the window, press "ALT" key and the middle button of the mouse and the cursor instantly become an arrowhead. You can then move in the direction that you want to resize.
2. Press At + F8
The "Alt + F8" hotkey is a quick keyboard shortcut to activate the resize mode. Once in the resize mode (with a translucent overlay), you can use the arrow key to resize the window horizontally or vertically. Once you are done, hit Enter to return to the window mode.
3. Configure own hotkey via Compiz
If you are using Compiz, it comes with several more options that you can configure.
Open your CompizConfig Settings Manager (System -> Preferences -> CompizConfig Settings Manager).
Scroll down the list to find "Resize Window".
Click on it to enter its configuration page. From here, you can enable and assign the hotkey for different resize mode. In this example, I have enabled the "Initiate Outline Window Resize" mode and assign the hotkey "Alt + Super + W" to activate it.
That's it. This should solve your window resizing woes.


Altova MapForce 2022 Enterprise Edition
Relative and Absolute Paths
Home Prev Top Next
This topic explains how to use absolute and relative paths of the files referenced by your component. An absolute path shows the full location of a file, starting with the root directory. Examples of absolute paths can be seen in the red frame in the screenshot below. A relative path shows the file location which is relative to the current working directory: e.g., Books.xml.

In the Component Settings dialog box (see example below), you can specify absolute or relative paths for various files which can be referenced by the component. The list of these files is given below:

Input files from which MapForce reads data;
Output files to which MapForce writes data;
Schema files, which are applicable to components with a schema;
Structural files, which are used as input or output parameters of user-defined functions and variables;
StyleVision Power Stylesheet (*.sps) files, which are used to format data for outputs such as PDF, HTML and Word;
Database files in the case of database components (Professional and Enterprise editions).

Copy-paste and relative paths
When you copy a component from a mapping and paste it into another mapping, MapForce checks whether the relative paths of schema files can be resolved against the folder of the destination mapping. If the paths cannot be resolved, you will be prompted to make the relative paths absolute.

Broken paths
When you add or change a file reference in a mapping, and the path cannot be resolved, MapForce displays a warning message. Broken path references may happen in the following cases:

You use relative paths and then move the mapping file to a new directory without moving the schema and instance files.
You use absolute paths to files in the same directory as the mapping file and then move the directory to another location.

When one of these scenarios happens, MapForce highlights the component in red. The solution is to double-click the red component header and update any broken path references in the Component Settings dialog box. See also Change Component Settings.

Example: XML component
The example below shows how file paths are used in an XML component. If you want to save all the mapping-related files relative to the mapping file (.mfd), check the box Save all file paths relative to MFD file at the bottom of the Component Settings dialog box. This is the default and recommended option that affects all the files referenced by the component (shown in the red frame in the image below). If you have not saved your mapping yet, you will see absolute paths to the schema and/or instance files in the Component Settings dialog box. To see relative paths in the Component Settings dialog box, take the following steps:

1.Create a new mapping and add a structural component: e.g., an XML file with an XML schema assigned to it.
2.Double-click the header of the component to open the Component Settings dialog box.
3.Check the box Save all file paths relative to MFD file at the bottom of the Component Settings dialog box.
4.Save your mapping.
5.You can now open Component Settings again to check the relative paths in the relevant text fields.

Note:Paths that reference a non-local drive or use a URL will not be made relative.
MF_MapFund_Components_Paths_RelatAbs1
When the check box Save all file paths relative to MFD file is selected, MapForce will keep track of the files referenced by the component even when you save the mapping to a new folder. If all the files are in the same directory as the mapping, the path references will not be broken when you move the entire directory to a new location on the disk.

The setting Save all file paths relative to MFD file applies to the following files:

Structural files used by complex input or output parameters of user-defined functions and variables of complex type;
Input or output flat files (Professional and Enterprise editions);
Schema files referenced by database components which support XML fields (Professional and Enterprise editions);
Database files (Professional and Enterprise editions);
Input or output XBRL, FlexText, EDI, Excel 2007+, JSON files (Enterprise Edition only).

Example: Database component
When you add a database file such as Microsoft Access or SQLite to the mapping, you can enter a relative path instead of an absolute one in the Select a Database dialog box (see screenshot below). Before entering relative file paths, make sure to save the .mfd file first. If you want to change the path of a database component which is already in the mapping, click Change in the Component Settings dialog box.
MF_MapFund_Components_Paths_RelatAbs2
Note:When you generate program code, compile MapForce Server execution files (.mfx), or deploy the mapping to FlowForce Server, a relative path will be converted to an absolute path if you select the check box Make paths absolute in generated code in the mapping settings. To find out more, see About Paths in Generated Code.

SLANESVILLE, W.Va. -- Ice Mountain, the Hampshire County peak that earned its name and a recent National Natural Landmark designation for the refrigeration effect that takes place inside a sloping mass of boulders along its base, shows signs of thawing.
Since 1983, researchers from West Virginia University have been using temperature loggers to track the temperature of air flowing from some of nearly 150 natural vents found at the base of a 60-foot-thick boulder field that extends nearly to the top of the 1,500-foot peak.
The boulder field, or talus slope in geological terms, "is a very good cold-air trap," said Dr. J. Steven Kite, the geology professor at WVU who leads the Ice Mountain monitoring program. "The talus slope provides a lot of intake area, and the R-value of having 60 feet of rock for insulation must be in the thousands."
In winter, dense, cold air sinks deep into the Oriskany sandstone talus, and ice masses form in the spaces between the rocks. "By late winter," Kite said, "everything freezes and the vents close."
As the weather warms in spring and summer, air much cooler than outside temperatures is released through the ice vents at the base of the talus slope. The ice vent section at the bottom of the slope is about 250 yards long and 30 yards wide. "It takes months for the cold air to come out," Kite said.
For the past three years, though, air blowing from the vents at the base of Ice Mountain has reached above-freezing temperatures slightly earlier than usual. And this year, a 1 degree Celsius reading was attained on April 25, more than three weeks earlier than in any other year in which Kite and his graduate students have been logging temperatures.
Having the ice gone from Ice Mountain so early "is significant," said Rodney Bartgis, state director of The Nature Conservancy in West Virginia, which has protected a 159-acre section of Ice Mountain, including the ice vent area, since 1989. "There's reason to be concerned that a warming event may be going on."
A unique community of plants normally found at much higher latitudes and elevation has thrived in rocky soil near the ice vents probably since the end of the last Ice Age, according to Bartgis.
"It's one of the most remarkable features about this site," he said.
Dwarf dogwood, a plant that ranges from Eastern Canada to Alaska and also can be found at scattered sites above 4,000 feet in West Virginia, is found at an elevation of about 750 feet at the base of Ice Mountain. The bristly rose, also known as Arctic rose and the official provincial flower of Alberta, is another Canadian and Alaskan species that can be found at Ice Mountain, along with the twinflower, another plant normally found hundreds of miles to the north. At least six boreal, or Northern, plant species can be found near the base of Ice Mountain.
"Although this place and the plants that live here have likely persisted since the end of the Pleistocene [about 11,700 years ago], there is no promise that it will remain as it is through the coming decades," Bartgis said.
Kite said a lack of historic scientific data on Ice Mountain's natural refrigeration system makes it difficult to determine just how significant the current warming trend might be.

The book contains contributions from Southeast Asia, a diverse region where oral history work is still not widely known, and where it often (but not always) contends as fragments against dominant state narratives.
How does oral history contribute to your book?
The volume draws upon oral history fieldwork in Singapore, Thailand, Malaysia, Indonesia, and the Philippines, and deals with memory politics among a varied group of Southeast Asians: workers, communists, rebels, massacre survivors, villagers, and former leprosy patients.
Kah Seng Loh, Stephen Dobbs, and Ernest Koh (eds). Oral History in Southeast Asia: Memories and Fragments. New York: Palgrave Macmillan US, 2013.
What do you like about using oral history as a methodology?
In an academic sense, oral history in the region is incredibly rich and capable of disturbing dominant narratives. But it does not always do so, possessing a sometimes ambivalent relationship to power. Speaking about the past in the context of Southeast Asia—a bundle of nation-states with conflicted recent political and social histories—is both rewarding and challenging work.
Why will fellow oral historians be interested in your book?
Southeast Asia offers interesting ways to understand oral history in the context of decolonization, the Cold War and counter-insurgency, rapid industrialization, and medicalization of the state. Our book is a small (and old) one, and hopefully will spur further regional perspectives and trans-regional comparisons on oral history.
That oral history remains relevant and valuable today in many places in the world, particularly due to some of its original impetus, namely the relationship between memory, power and social change.

Theorem 4.3
Assume that all assumptions of Theorem 3.5 are satisfies and Ψ is lower semicontinuous. Then (4.1) is well-posed if and only if
$$ \zeta (\delta ,\epsilon ) \neq \emptyset , \quad \forall \delta ,\epsilon > 0 $$
and
$$ \operatorname{diam} \zeta (\delta ,\epsilon ) \to 0 \quad \textit{as } (\delta , \epsilon ) \to (0,0). $$
Proof
The necessary part directly follows from the proof of Theorem 3.5, so it is omitted. Conversely, suppose that \(\{x_{n}\}\) is an approximating sequence of (4.1). Then there exist \(u_{n}\in T(x _{n})\) and a sequence of positive real number \(\epsilon _{n} \to 0\) such that
$$\begin{aligned}& \lim_{n\to \infty }\sup \varPsi (x_{n}) \leq _{P} \inf_{y\in \varOmega } \varPsi (y), \end{aligned}$$
(4.2)
$$\begin{aligned}& \bigl\langle Q(u_{n},x_{n}), \eta \bigl(y,g(x_{n}) \bigr)\bigr\rangle + \varphi \bigl(g(x_{n}),y\bigr) + \epsilon _{n} e \nleq _{P^{0}} 0, \quad \forall y \in \mathcal{D}, \end{aligned}$$
(4.3)
which implies that
$$ x_{n} \in \zeta (\delta _{n},\epsilon _{n}), \quad \text{for } \delta _{n} \to 0. $$
Since
$$ \operatorname{diam} \zeta (\delta ,\epsilon ) \to 0 \quad \text{as } (\delta , \epsilon ) \to (0,0), $$
and \(\{x_{n}\}\) is a Cauchy sequence converging to \(x_{0} \in {\mathcal {{D}}}\) (because \(\mathcal {{D}}\) is closed). By the same argument as in Theorem 3.5, we get
$$ \bigl\langle Q(u_{0},x_{0}), \eta \bigl(y,g(x_{0}) \bigr)\bigr\rangle + \varphi \bigl(g(x_{0}),y\bigr) \nleq _{P^{0}} 0, \quad \forall u_{0} \in T(x_{0}), y \in \mathcal{D}. $$
(4.4)
Since Ψ is lower semicontinuous,
$$ \varPsi (x_{0}) \leq _{P} \lim_{n\to \infty } \inf \varPsi (x_{n}) \leq _{P} \lim_{n\to \infty } \sup \varPsi (x_{n}). $$
By using (4.1), the above inequality reduces to
$$ \varPsi (x_{0}) \leq _{P} \inf_{y\in \varOmega } \varPsi (y). $$
(4.5)
Thus, from (4.3) and (4.4), we conclude that \(x_{0}\) solve (4.1). The uniqueness of \(x_{0}\) directly follows from the assumption
$$ \operatorname{diam} \zeta (\delta ,\epsilon ) \to 0 \quad \text{as } (\delta , \epsilon ) \to (0,0). $$
This completes the proof. □
Example 4.4
Let \(\mathcal {{X}}= \mathcal {{Y}}={\mathbb{R}}\), \(\mathcal {{D}}=[0,1]\) and \(P=[0,\infty )\). Let us define the mappings \(\varPsi :\mathcal {{D}}\to {\mathbf {{R}}}\), \(T: \mathcal {{D}} \to 2^{L(\mathcal {{X}},\mathcal {{Y}})}\), \(\varphi : \mathcal {{D}} \times \mathcal {{D}} \to {\mathcal {{Y}}}\), \(\eta : \mathcal {{X}} \times \mathcal {{X}} \to {\mathcal {{X}}}\), and \(Q:L(\mathcal {{X}},\mathcal {{Y}})\times \mathcal {{D}} \to L(\mathcal {{X}},\mathcal {{Y}})\) as follows:
$$ \textstyle\begin{cases} \varPsi (x)= \vert x^{3} \vert ; \\ T(x)=\{u:{\mathbb{R}} \to {\mathbb{R}} \mid u \text{ is a continuous linear mapping such that } u(x)=-x \}; \\ g(x)=x; \\ \varphi (g(x),y)=y-x; \\ \eta (g(x),y)=\frac{1}{2}(y-x); \\ Q(v,x)=v; \\ \alpha _{g}=-x^{2}. \end{cases} $$
Consider the optimization problem with generalized \((\eta ,g,\varphi )\)-mixed vector variational-type inequality constraints:
$$ \begin{aligned} &P\text{-minimize } \bigl\vert x^{3} \bigr\vert \\ &\quad \text{subject to } x \in \varOmega , \end{aligned} $$
(4.6)
where
$$ \varOmega = \biggl\{ x \in {\mathcal {{D}}}\Bigm| \exists u \in T(x) \text{ such that } \biggl\langle u, \frac{1}{2}(x-y)\biggr\rangle + y-x \nleq _{P^{0}} 0, \forall y \in {\mathcal {{D}}}\biggr\} . $$
We see that \(\varOmega =\{0\}\). Since
$$ \zeta (\delta ,\epsilon )=\biggl\{ x \in {\mathcal {{D}}} \Bigm| \exists u \in T(x) \text{ such that } \bigl\vert x^{3} \bigr\vert \leq _{P} \delta \text{ and } (y-x) \biggl(1+\frac{x}{2} \biggr)+ \epsilon \nleq _{P^{0}} 0, \forall y \in {\mathcal {{D}}}\biggr\} , $$
we have
$$ \operatorname{diam} \zeta (\delta ,\epsilon )\to 0 \quad \text{as } (\delta , \epsilon )\to (0,0). $$
It is easily verified that T is relaxed η-\(\alpha _{g}\)-P-monotone with respect to the first variable of Q and g, and all assumptions of Theorem 4.3 are satisfied. Hence (4.6) is well-posed.
Theorem 4.5
Let all conditions in Theorem 3.7 hold and let Ψ be lower semicontinuous. Then the problem (4.1) is well-posed if and only if it has a unique solution.
Proof
The necessary condition is obvious. Conversely, let (4.1) have a unique solution \(x_{0}\). Then
$$\begin{aligned}& \varPsi (x_{0})=\inf_

Sloshing due to ground motion develops large pressure on the walls of water retaining tanks. This paper evaluates the efficacy of padded walls on the reduction of sloshing effects in rectangular water storage tanks subjected to ground motion. An analytical solution based on velocity potential function is provided to obtain the response of rigid and padded wall tanks in terms of the wave elevation, maximum pressure on the tank wall and FFT spectrum of pressure on the water surface. In the proposed method, the boundary condition on the tank wall is kinetic representing pressure distribution on the tank walls against the usual methods with kinematic boundary condition only. The fluid is assumed to be inviscid, incompressible, and irrotational. Tanks with and without padded walls are evaluated under different types of ground motions classified as near source and far-field records. The results show noteworthy effect of the padded wall on reduction of above-mentioned sloshing responses.


failed the game
No doubt they would have risked too much on any given trial. They could have had a string of seven or more losing trades that would have made it impossible for them to recover their initial starting balance? Or It could have been that some participants had only one, two, or three HUGE LOSSES that reduced their account down to extremely low levels.
Also, some participants probably tried to increase their stake size after one, two or three losses hoping that they could recover the loss. (Martingale strategy). Problems with martingale strategies develop when the streak of consecutive losses causes the risk / reward ratio to blow out of proportion. What happens when there is a streak of fifteen losses in a row? (Is it logical to risk losing $700 by trying to save $100?)
On the other hand if the participants had used Anti-martingale strategies, which means increasing the amounts they risked on each trial after winning streaks they would have done better.
The lesson's from the experiment with the 40 Ph.D.s is loud and clear.
1.Do not risk too much money on any one position due to unknown timing and length of losing streaks.
2.There is a correct (Optimum) amount of money to risk on each trial. (position size). This amount can be calculated dependent on the rules of the game /system.
In case you are wondering what was the correct answer to the position size in the above experiment. The optimum amount to achieve the maximum gain was for the participants to risk 20 percent of their new equity each time. The balance of their accounts would have grown to about $7,500.
For trading purposes risking 20% of your closing balance would be regarded as a very high risk strategy. Very poor money management. Lets look at the effect on our account should we start with a string of consecutive losses.
Our starting account balance $1,000
less 20% loss number1 -$200 $800
less 20% loss number2 -$160 $640
less 20% loss number3 -$128 $512
less 20% loss number4 -$102 $409
less 20% loss number5 -$82 $327
less 20% loss number6 -$65 $262
less 20% loss number7 -$52 $209
After a bad string of 7 losses our account is now down to $209. We now need to make 378.5% to recover. See how risking 20% of our account balance is way to much.
Risk between 1% to 3%
Jack Schwager's book Market Wizards (1989) day and trend follower Larry Hite says about money management;
"Never risk more than 1% of the total equity on any trade. By only risking 1%, I am indifferent to any individual trade."
The general consensus on money management is that a trader should limit his risk up to about 3% maximum on any one position.
Does this seem reasonable?
Let check it out with the above previous seven in a row loss.
Our starting account balance $10,000
less 3% loss number1 -$300 $9,700
less 3% loss number2 -$291 $9,409
less 3% loss number3 -$282 $9,127
less 3% loss number4 -$274 $8,853
less 3% loss number5 -$266 $8,587
less 3% loss number6 -$258 $8,329
less 3% loss number7 -$250 $8,079
After our bad string of 7 losses our account is now down to $8,079. We now need to make 23.8% to recover.
Using our maximum money management 3% risk rule shows a recovery from a shocking 7-in-a-row loss situation is very feasible. Only 23.8% to recover compared to our earlier example of 378.5% if we risked 20% of our balance per trade. See how good money management can protect us!
As you noticed, we had to increase our account size from $1,000 to $10,000 to make our stop loss sizes reasonable. This shows that the smaller your account the more difficult it will be to apply proper money management rules.

A recent study shows that propranolol hydrochloride (PRO) related substances may also reduce the stability of tablets in storage. Therefore, it is necessary to control the level of PRO related substances in tablets. However, the analysis in U.S. pharmacopoeia could not detect PRO related substances. To overcome this, we developed a new method which can detect PRO, hydrochlorothiazide (HCT) and all of their impurities. In this study, validation studies were also performed, linear relationship with a good correlation coefficient (r2)>0.990 was found of both PRO impurities and HCT impurities in the range of 0.12-0.60, and 0.15-0.75 μg/ml respectively. Acceptable intra- and inter- assay precisions were achieved. Accuracy and robustness were reported as percent recovery, and all the recoveries were at the range of 70-130%. After validation, the methods were successfully used in the routine quality control of the tablets.

This paper analyses customer satisfaction with services of the Sokoine National Agricultural Library (SNAL) using a mixed method approach. Both qualitative and quantitative data were collected using questionnaire and interviews, which were supplemented by document analysis. A total of 72 respondents were selected using simple random and purposive sampling procedures. Data were analysed descriptively and were presented in tables, pie charts and percentages. The expectancy-disconfirmation theory with Four-Level Zone of Tolerance (ZoT) developed by Oliver (1980) guided data analysis in this study.
Findings indicate that leaning materials and services provided by SNAL are relatively sufficient due to satisfaction level of majority of customers being over 50%. This shows that the library has relevant learning materials which mostly meet users' satisfaction. However, some respondents showed dissatisfaction with challenges they faced in accessing library resources due to: poor arrangement of books in shelves that made users to spend a lot of time in searching materials, lack of adequate security in the Library that made some users' properties in their bags temporarily kept in the library being stolen and lack of good customer care practices from some library staff.
The study recommends the factors prompting users' dissatisfaction be addressed so as to regain customers' satisfaction and loyalty to the library.

After you receive your sundial follow these instructions to install the sundial.
How to create an interactive painted sundial:
1) Order a Sundial, on the checkout page include your location as an address or GPS coordinates.
2) Our technology creates a specific template for your exact location on the earth, no two are alike.
3) A full-scale template is cut out of durable Coreplast, which is like corrugated cardboard, only plastic
4) We ship you the complete template. Follow the steps below to create the sundial by painting the sundial on your location.
5) You stand on the Sundial when its sunny, and your shadow will tell the time!
Step 1: Find the geographic coordinates of the location, then create a CAD drawing of the sundial.
Delete or modify, so people can understand they will receive the kit. Then they will follow these steps to install the sundial.
Step 2: Using precision tools cut the stencil to exact specifications.
Step 4: Align to true north.
How are people going to do this step? There are compass apps you can use on your phone. May the instructions can reference a popular app if people do not have this tool. What do you think?
Step 3. Lay the stencil out on the blacktop.
Step 4: Paint the sundial on the location.

Below I will share how I created the Chevron Canvas, and in a separate post I will detail how to create the flower.
There are several ways to get a chevron pattern onto a canvas. If you can find a piece of fabric that already has the pattern on it, you can simply staple that around your canvas and be done with it. If you go the painting route (which I did), you also have to choose to use painter's tape, or freehand it. Personally, I knew I would get frustrated with the tape, so instead I used a flat-edged foam brush to make the lines straight.
- Blank white canvas
- Acrylic Paint in desired colors
- Pencil with white eraser
- Determine how wide you want your stripes to be, and balance that with the dimensions of your canvas. For example, I wanted 1" wide stripes. My canvas was 12"x12" so it was pretty straightforward.
- Measure along each side of the canvas, making marks for the width of your stripes. Make your pencil marks lightly so that they can be erased as needed later. Then connect your marks across to the opposite side of the canvas, resulting in a checkerboard pattern.
- Connect the corners of the checkerboard squares to create your chevron pattern. Erase the pencil marks within the chevron stripes as well as possible.
- Paint your stripes. The foam brush with the flat edge will make it easier to create a sharp line. If you are using more than one color, I recommend painting with one at a time, letting the paint dry between colors. **There is a chance you might run into the same problem I did: I wasn't planning on painting the white stripes, but my pencil marks were stubborn, so I had to do some white paint touch-ups.**

2021 : DESIGN OF VIDEO STABILIZATION SYSTEM AS A SUPPORT FEATURE IN THE UAV CAMERA
Mohamad Abdul Hady S.T., M.T.
Videos recorded on UAVs often suffer vibration effects due to unwanted camera movements. Unstable videos make it difficult for users to observe certain targets. Therefore, this research designed a video stabilization system using image processing to reduce vibration effects in a video. The video stabilization system consists of four main processes. Firstly, a feature point detection and tracking process between two consecutive frames to get the camera movement path. This process applied Shi-Tomasi corner detector and Optical flow matching. Secondly, motion estimation is performed based on affine transform. Third, the simple low pass filter is applied to determine a motion compensation for the object movement in the video. Lastly, video frames are transformed based on compensation value to reduce the vibration effect. The test results on the implementation of the video stabilization system show video quality improvement based on a decrease in SAD level and increase the SSIM level.

The Egyptian Cultural and Educational Bureau (ECEB) in Washington DC plays a major role in variety of educational activities. Following is a list of the Main ones:
ECEB plays a catalyst role in enhancing the cooperation between education and research centers in Egypt and their counterparts in the United States. ECEB facilitates development of the agreements and memorandums of understanding and supervises the progress of the joint programs thereafter.
ECEB identifies areas of new developments in all scientific fields, observe the rating of the universities and delineates scholars of greatest accomplishments for the benefit of directing future Egyptian missions and training programs in the United States.
ECEB plays a major role in supervising Egyptian students and scholars studying or conducting research in the United States. ECEB helps in placing the students in appropriate universities, monitors their academic progress and compiles the abstracts of their completed theses.
ECEB keeps track of the accredited programs and accrediting bodies and advise on the equivalency of the degrees granted by schools, colleges and universities in the United States to their corresponding degrees in Egypt.
ECEB administers pre-university exams, according to the Egyptian Ministry of Education curricula, for Egyptian students residing in the United States with their guardians. The exams are prepared and sent by the Ministry of Education in Egypt for the following grades: third, fourth, fifth and sixth elementary level, first, second and third preparatory level, and first secondary level. Answer papers are graded in Egypt.
The Egyptian Cultural and Educational Bureau in Washington DC interacts very closely with graduate student sent on governmental scholarships or granted study leave by institutions falling under the auspices of the Ministry of Higher Education and scientific research. ECEB coordinates the following programs.
1. Government Mission Program (GM):
The GM Program is directed to Egyptian students of high caliber to pursue their PhD work in the United States in selected fields. The Egyptian Government sponsors and fully supports the PhD candidates over four years. In some cases, the mission with the government support can be extended additional nine months. Beyond the four years the candidate should find other means of support to complete the degree requirements. Awardees of the GM Program should return to their mother institutions to serve.
2. Joint Supervision (JS) and Data Collection (CD) Programs:
The program is directed to assistant lecturers in Egyptian Universities, graduate students with Masters Degrees, registered for PhD degrees in Egyptian universities. The student would come to the United States for a period of one year to collect data or conduct further research for his dissertation. The student is fully supported by the Egyptian Government. For the JS Program, the student is supervised by an Egyptian professor and an American professor is selected as his co-supervisor. The American co-supervisor is invited for two weeks to Egypt while the student is still in Egypt to agree on the study program and plan the student activities in the US. The Egyptian supervisor visits the student, two weeks, during his stay in the US to advise and monitor progress. Air tickets and per diem for the trips of both supervisors is covered by the Government of Egypt. CD and JS missions can be extended beyond the first year provided that the mother institution of the student agrees and that the student finds means to support his stay.
3. The Post Doctoral Sabbatical Program (SAB):
Candidates for the SAB Program should have their PhD degrees from Egyptian universities. They join an American university or research institute for a period of three to six months. The Egyptian Government fully supports their stay. They work closely with mentors within the host departments.
4. Self Financed (SF) and Study Leave (SL) Students:
This group of students includes demonstrators (graduates with Bachelors Degree) and assistant lecturers (graduates with a Masters Degree) who are appointed in an Egyptian University or Research Center that belongs to the Ministry of higher Education and Scientific Research. They come to the United States for higher degrees. They support themselves through assistantships offered by American universities or through family savings. Their tenure positions in Egypt are kept while they are working to complete their degrees. Other privileges offered by the government include return air tickets back home and other thesis preparation allowances.
5. Student under Scientific Supervision:
Egyptian students residing in the United States with their guardians and attending American high schools and universities should register with ECEB as students under scientific supervision. Their military service is postponed while they are conducting full load of study. Egyptian students enrolled in the American Diploma who will be joining Egyptian universities should be registered with ECEB as students under scientific supervision.
We would like to extend a warm welcome to all visitors of the website of the Egyptian Cultural and Educational Bureau in Washington DC. Our office runs under the auspices of the Ministry of Higher Education and Scientific Research in Egypt in harmony with the Embassy of Egypt in the United States. Our services and programs are directed to Egyptian students and scholars studying, teaching or conducting research in the United States and to all Americans interested in Egypt's rich history and cultural diversity. We are dedicated to facilitate linkage between institutes and centers of excellence in Science, Technology, Education, Arts and Humanities in Egypt and their counterparts in the United States. The objective of our work is to contribute positively in strengthening cultural understanding of values and beliefs in both nations.
This site offers a description of the ECEB ongoing programs and provides links to other sites that contain useful information about educational and cultural aspects of Egypt. Events that ECEB organizes or participates in are posted. Please visit our site frequently. We are counting on your feed back to make it more informative and useful.

text: This letter presents a fully autonomous robot system that possesses both terrestrial and aerial mobility. We firstly develop a lightweight terrestrial-aerial quadrotor that carries sufficient sensing and computing resources. It incorporates both the high mobility of unmanned aerial vehicles and the long endurance of unmanned ground vehicles. An adaptive navigation framework is then proposed that brings complete autonomy to it. In this framework, a hierarchical motion planner is proposed to generate safe and low-power terrestrial-aerial trajectories in unknown environments. Moreover, we present a unified motion controller which dynamically adjusts energy consumption in terrestrial locomotion. Extensive realworld experiments and benchmark comparisons validate the robustness and outstanding performance of the proposed system. During the tests, it safely traverses complex environments with terrestrial aerial integrated mobility, and achieves 7 times energy savings in terrestrial locomotion. Finally, we will release our code and hardware configuration as an open-source package.

I. UCSF Leadership
UCSF leadership plays a critical role in securing Electronic Information Resources (EIR). They do so by making direct statements to the campus, Medical Center, and labs about the need to ensure that restricted data is protected while it is stored, used, and transmitted by academic and administrative units throughout the University. Such statements lead to better understanding of standards of accountability for all employees during the regular discharge of their duties and in the case of security incidents. Establishing accountability involves assigning responsibility for the consequences of a security event. Leadership must support the enforcement of standards of accountability for safeguarding restricted data through employee performance management processes.
II. Individual Responsibilities
All members of the campus community (faculty, staff, students, and student employees) are required:
- to identify, to the best of their ability, any restricted data that resides on their individual devices and

An assessment of present erosion and sedimentation conditions in the Ca?ada de los Alamos basin was made to aid in estimating the impact of off-road-vehicle use on the sediment yield of the basin. Impacts of off-road vehicles were evaluated by reconnaissance techniques and by comparing the study area with other offroad-vehicle sites in California.
Major-storm sediment yields for the basin were estimated using empirical equations developed for the Transverse Ranges and measurements of gully erosion in a representative off-road-vehicle basin. Normal major-storm yields of 73,200 cubic yards would have to be increased to about 98,000 cubic yards to account for the existing level of accelerated erosion caused by off-road vehicles. Long-term sediment yield of the Ca?ada de los Alamos basin upstream from its confluence with Gorman Creek, under present
conditions of off-road-vehicle use, is approximately 420 cubic yards per square mile per year--a rate that is considerably lower than a previous estimate of 1,270 cubic yards per square mile per year for the total catchment area above Pyramid Lake.

This building is located at 181 East Broad Street, Columbus and has a long history associated with it. First built for Benjamin Smith, noted railroad contractor in the mid-nineteenth century, the house was temporarily the Ohio Governor's mansion in the 1880s, then sold to the Columbus Club, a group of prominent business leaders, in 1887. The contract for building his home provided that each of the bricks used in the structure was to be pressed in Philadelphia, wrapped separately in paper, and shipped to Columbus, Ohio.
The two-story mansard building is styled in the French Second Empire tradition with numerous ornamental elements such as round-headed mansard roof dormers, hoodmolds formed of rope molding with centered, stylized anthemion motifs, slate roof tiles, and intricately detailed paneled brick chimneys.
The interior captures Victorian style with a grand curving stairway, mantelpieces, and hardwood trimmed arched doorways.

different at different points, as illustrated in Fig. 5.6. This is because the plate characteristic of the diode is not a straight line.
The resistance offered by a diode to alternating current is known as ac plate resistance, rp. It is defined as the ratio of a small change in plate voltage across a diode to the resulting change in plate current i.e.,
AC plate resistance,
For the operating point P on the plate characteristic, the inverse of the slope of the tangent line to the characteristic at point P provides ac plate resistance.
As the tubes are generally operated with ac, therefore, ac plate resistance is much more important than dc plate resistance. The ac plate resistance can be determined from plate characteristic by considering a small change of plate voltage half way on each side of the operating point. The ac plate resistance of a diode is also called its dynamic resistance.

Farmers around the world: Avocado grower in Israel wins the "Excellent Farmer 2006 Awards"
Mr. Zvi Harat (Ziki to his friends, including myself who has worked closely with him in the past), aged 68 is an avocado grower from Kibutz Givat Brenner, situated about 45 minutes drive south of Tel Aviv, Israel. Ziki has been working in the Kibutz avocado orchard since it was first planted in 1978. Our story is about Ziki, the avocado orchard he planted 30 years ago, and recognition of his contribution to the avocado industry in Israel.
In early 2007, Carmel Agrexco - the largest exporter of agricultural produce in Israel - presented Ziki with the "Excellent Farmer for 2006" in the export fruit sector. The award states that Ziki "is one of the pillars of the avocado sector in Israel", and that his achievements are reflected by the high productivity of the orchard and ratio of exported fruit. Ziki was also praised for "working in close collaboration with research and extension, and his team for taking an active part in the stewardship of young agronomy students" at various research forums.
As far as is known, the first avocado (Persea Americana Mill) trees were brought to Israel in 1908 to the French Monastery in Latrun, near Jerusalem (Shachar, 1982). Until the early fifties, avocado trees planted commercially did not exceed 2,000 and were grown mostly in the central coastal plain. Since the end of the fifties, many commercial orchards have been planted in most parts of Israel, and - by 1975 - the total area had increased to 3,600 hectares. Since 1990, the avocado area in the country declined from almost 9,000 to 5,100 ha in 2005, yet productivity tripled from 566 to 1679 kg/ha (FAOSTAT, November 2007). Many rootstocks are now used, depending on the soil and climatic conditions. For example, West Indian rootstocks have been developed for planting/growing in heavy lime soil or where irrigation water has a high salt content.
The Kibbutz Givat Brenner avocado plantation is planted over 32 hectares, on relatively heavy soil (~50% clay) with pH=7.5. Planting during recent years has been in high beds (up to 80 cm) and the whole orchard is now drip irrigated with three laterals per row, an emitter every 30 cm, and a discharge rate of 1.8 l/h each. The main cultivars are Hass, Etinger, Fuerte and Reed. Irrigation water used is mostly treated wastewater (TWW) to a secondary tertiary level, with levels of Cl ranging from 100 ppm at the beginning of the irrigation season (April) to 250 ppm Cl at the end of the irrigation season (November).
During the last 25 years, Ziki has regularly sampled leaves from sub-plots and by cultivar, from which a detailed fertilization program is prepared. All fertilization is done via fertigation, which is fully controlled by a PC situated in the orchard and at Ziki's home, 15 kilometres away. Application rate of nutrients is 300, 60 and 400-650 kg of N, P2O5 and K2O respectively, per hectare. During the last few years, Ziki has started applying SOP in winter to deliver some of the high potassium levels required, and used phosphoric acid as the P source, applied towards the end of the summer. This has the added benefit of also cleaning the drip system. Source of N is ammonium nitrate and ammonium sulphate solutions, with reduced Cl levels of potassium fertilizers. Constant iron deficiency requires the application of 10 litres/ha of dissolved sequestrin (FeEDDHA).
I asked Ziki how he is able to pay for all these expensive inputs. "Well," he said," you should ask first about the cost of water." I did. Ziki pays between USD 0.2 to 0.4 per cubic metre (m3), and uses about 10,000-12,000 m3/ha. "This is our most expensive input, and we do whatever we can to make optimal use of the water we have," he explained. During the last four years, Ziki (and the kibbutz) have been significantly rewarded for the extensive investment in the orchard, and he harvests close to 20 mt/ha every year. He estimates the total inputs (including labor) at approx. USD 10,000/ha, and returns at approximately USD 13,000/ha.
Avocado research in Israel is carried out in close participation with farmers, and Ziki is a member of the R&D team at the Israeli Avocado Consortium. The consortium receives its funding from growers, and the government matches this contribution. Researchers at the Faculty of Agriculture (Hebrew University of Jerusalem), ARO Volcani Center and applied research centers, funded and run by farmers, compete for research grants. According to Ziki, the main challenges that avocado growers in Israel face today are improving the size of Hass, reduction in yield variations, biological pest control, and better use of treated wastewater.
I asked Ziki about the award he received and what it means to him and to the kibbutz where he has lived since he was born. "For me", he said, "the meaning of the award is the message it delivers of the need to assist the younger generation to see that there is a future in agriculture."
Thank you Ziki. We congratulate you on winning this prestigious award and we wish you many more fruitful years in the field.

Network Analyzer Match-Up: E5071C vs E5080B
2020-02-11 | 5 min read
Recently, Keysight introduced the E5080B ENA vector network analyzer. It's easy to look at the specs and get lost in the numbers, but seeing a real-world example gives the numbers meaning. So, I ran a small test.
How do the E5071C and the E5080B network analyzers perform measuring the same device with the same stimulus? In this head-to-head matchup I make simple S-parameter measurements on a bandpass filter with both instruments.
Looking at the specs, we can see the E5080B has better numbers on paper.
|Dynamic Range @ 10 GHz IFBW, 4 GHz||123 dB||140 dB|
|Trace Noise (dB rms), 4 GHz||0.003 (70 kHz IFBW)||0.0015 (10 kHz IFBW)|
|Cycle Time (2-p Cal, narrow span, 201 pts, typical)||5 ms (100 kHz IFBW)||2.2 ms (1 MHz IFBW)|
|IF Bandwidth||10 Hz to 1.5 MHz||1 Hz to 15 MHz|
But how do the numbers affect performance in the real world? Is the E5080B better or are legacy systems still good enough?
I did a hands-on comparison to answer these questions. I swept frequency on a bandpass filter to get S11 and S21 responses. Here are the measurement parameters I used:
- Start Frequency: 8 GHz
- Stop Frequency: 12.5 GHz
- IF Bandwidth: 1 kHz
- Number of Points: 201 Points
On the E5071C, the noise floor for this measurement was at about -85 dB. Using the same stimulus and filter, the E5080B had a noise floor of about -95 dB.
But what if we take it a step further, and bump the IF bandwidth from 1 kHz to 100 kHz? If time is crucial for your measurements, a bigger IF bandwidth provides the speed you need. Now, we're taking our measurement 100 times faster.
On the E5080B, the new noise floor with the wider IF bandwidth is -80 dB. This is close to where the E5071C was with a 1 kHz IF bandwidth.
Changing the IF bandwidth to 100 kHz on the E5071C gives us a much higher noise floor — about -60 dB.
This quick test shows us that the improvements to the E5080B's dynamic range and trace noise make a significant difference on even a basic measurement. If speed is important to you, the flexibility to use a wider IF bandwidth and a faster cycle time give the E5080B a strong advantage in simple S-parameter measurements.
Beyond S-parameters, the E5080B truly shines. Featuring the same firmware as the high-end PNA series network analyzers, the E5080B supports applications for spectrum analysis, pulsed measurements, noise figure measurements, and more. As you can also see in the comparison video, the updated E5080B user interface adds some quality-of-life improvements like the quick setup wizard, making measurement setup fast and simple.
Modern RF devices often require more than just S-parameters, so you need a flexible and integrated network analyzer to keep up with tomorrow's challenges. The white paper below describes more ways the E5080B improves your workflow with intuitive applications for advanced measurements.

Step 1 - Wrap teflon strip (PTFE) around thread
Hexagon Hotends tend to be leaky, when they are hot, if you don't take some precautions. So filament will drop outside from top of the thermal block. This happens due to different extension coefficients of the thermal block and the stainless steel thread.
Step 2 - Fit thermal block and filament tube together
Screw the filament tube into the thermal block.
Step 3 - Carefully tighten the connection
Tighten the connection between the filament tube and the thermal block. Be carefully not to overstress the thread!
Step 4 - Assemble heating cardridge
Assemble the heating cardridge into the designated hole of the thermal block and secure with set screw. It's a good idea to add some heat-conductive paste to the cartridge befor inserting into the hole. This will improve thermal flow.
Step 5 - Prepare NTC assembly
Add some heat-conductive paste into the hole for the NTC. This will insure a good thermal coupling between the thermal block and the NTC. You might alternativly glue the NTC into the hole, but you must use glue, which is able to withstand around 300°C (572°F).
Step 6 - Assemble NTC
Insert the NTC glas body into the designated hole.
Step 7 - Retighten connection on heated hotend
Connect the hotend to your printer controller and heat up the hotend to around 260°C (500°F). Then tighten the connection between the filament tube and the thermal block again with care.
Over then shown on the picture you should do this without the silicone rubber protection. The rubber protection is very sensitive and will get cracks when you hold it with a gripper.
Step 8 - Assemble the silicone rubber:
Pull the silicone rubber over the thermal block.
Step 9 - Secure electrical wires
To avoid unintendtional dissconnects of the wires, especially of the NTC, secure the wiring with a wire or something equal.
If NTC looses contact the thermal block, the printer controller will heat up the temperatur until the thermal block will meld!
This will cause extreamly high danger of open fire!
Step 10 - Assemble the hotend with the holding plate
Fit the hotend into the holding plate of the colt end of the extruder.
Step 11 - Align coldend with hotend
Align the filament conductions between cold and hot end by adding a piece of filament through both. Then connect the holting plate to the filament gear.
Step 12 - Fit extruder to the printer
The last step will be to fit the assembled extruder to your printer and connect all wires.
