One-dimensional Gaussian-core fluid: ordering and crossover from normal diffusion to single-file dynamics
The peculiarity of a bounded pair potential in combination with strong confinement brings some quite interesting new phenomenology in the structure and dynamics of one-dimensional colloidal systems. Such behaviour is atypical in comparison with colloidal systems interacting with potentials that diverge at the origin. In this contribution, by means of molecular dynamics simulations, a confined one-dimensional model of particles interacting via a Gaussian-core pair potential is studied. We explore the effects of confinement, density and temperature on the structural and dynamical correlation functions. Our findings indicate that the static and dynamic liquid-state anomalies already reported in open systems are also present in this 1D model system. Using the radial distribution function and the static structure factor to characterise the spatial ordering, it is observed that the system remains fluid at all densities. However, when the reduced temperature is above 0.03, it displays typical features of a liquid regime, i.e., there exist short-range spatial correlations among particles. In contrast, at lower temperatures and densities, where the particle–particle interaction dominates, the system behaves structurally and dynamically similar to a hard-core repulsive system. In such a region, interestingly, there is a crossover from a liquid to a solid-like regime. At any given temperature, the system undergoes a sort of reentrant structural behaviour as the density increases. At either high densities or temperatures, particle correlations vanish, thus, the system exhibits structural and dynamical properties similar to those of an ideal gas. To examine a possible correlation between the structural anomalies and the diffusive behaviour, the mean-square displacement and the self-intermediate scattering function are also computed. From these observables, we establish the thermodynamic phase-space points where the dynamical behaviour is non-monotonic. In conjunction with the observed anomalous diffusion, we have found a dynamical crossover from single-file diffusion, which is characteristic of one-dimensional systems with a well-defined hard-core, to the ordinary Fickian diffusion present in open systems.

Journal of Micro/Nanolithography, MEMS, and MOEMS • Open AccessWhispering-gallery modes of μ-optic silicon bottle resonator examined using a Fourier–Bessel eigen-state approach
The whispering-gallery mode space of a cylindrically symmetric silicon micro-optic bottle resonator with an axial Gaussian dielectric profile is theoretically examined. Maxwell's wave equation for the magnetic field, expressed in cylindrical coordinates, is converted into an eigenvalue problem using a Fourier–Bessel basis space to expand the inverse dielectric and field components. The order of the eigen-matrix is reduced using symmetry arguments and azimuthal order segmentation such that the matrix can be solved on a desktop PC. The eigen-space reveals that several states can be confined in the bottle region, whereas another set of states extends the axial length of the structure similar to ridge waveguide modes. The hollow core bottle is also presented as a design modification. The micro-optic bottle resonator structure size makes it directly compatible with silicon-based photonics increasing its potential as a key component in sensing, communication, and other applications.

Differential vulnerability in the hindbrain neurons was examined immunohistochemically during hindbrain ischemia in the gerbil. Hindbrain ischemia was produced by extracranial occlusion of the bilateral vertebral arteries just before their entry into the transverse foramen of the cervical vertebra. Local cerebral blood flow was measured by quantitative autoradiographic technique after 5 min of ischemia and was reduced to less than 5 ml/100 g per min in the cerebellum, the pons, and the medulla, indicating that severe and reproducible hindbrain ischemia was induced immediately after occlusion. For immunohistochemical investigation, four gerbils each were used for each ischemie period of 5, 10, 15, and 30 min. Immunohistochemical lesions, detected by the reaction for microtubule-associated protein 2, were visible in the lateral vestibular nucleus and the cerebellar interpositus nucleus even after 5 min of ischemia. These results suggested that these areas were more vulnerable than others, although blood flow was markedly reduced in various regions of the hindbrain. In contrast, areas related to respiratory or cardiovascular control were rather resistant to ischemia. The present study suggests that selective vulnerability during hindbrain ischemia depends mainly on different metabolic characteristics inherent to various neurons in the hindbrain.

The students with their invention
A group of seniors from the Department of Electronic Engineering at The American University in Cairo (AUC) recently unveiled their newest invention, a conceptual prototype of an automatic meter reading (AMR), a system which reads household power consumption and relays the information gathered to personal electronic devices. Under the supervision of Ayman Hassan, an adjunct in the department, the group collaborated to create the device that automatically sends accurate readings to personal electronics, including a PC or cell phone. The inventors say that this device can also be used to send the information to the Ministry of Electricity and Energy to keep track of the readings.
The members of the six-man team are enthusiastic about the potential benefits of their invention. Amr Henna believes innovations such as this one are overdue and could benefit the Egyptian economy. "After the January 25th revolution we need to catch up with the latest international electronic trends that use automated systems and have them produced in Egypt. This will reduce the market price tremendously," he says. Ahmed Megawer, another team-member, agrees that "it is high time that we pick up with the smart systems invented worldwide. Power failures like the ones we experienced last summer could have been avoided if consumption had been monitored." Sherif Mourad considers the potential benefit of accurate readings for cash-strapped families. "Consumers should stop guessing the numbers of their power consumption and they should be positive that they are paying money only for the consumed amounts as determined by accurate readings."
According to Ahmed Abou-Auf, chair of the Department of Electronic Engineering, the system has further applications in that it can record power consumption in remote areas and large towers that are difficult to reach. In addition, it allows for households to monitor their energy usage independently, giving them knowledge, that, he says, can empower the families to change their consumption behavior. Abou-Auf says the students will continue to produce production prototypes, conduct additional market research, and develop a business plan. The university will provide all the labs and research material needed and facilitate funding from investors.

X-Ray & Cryogenic Facility (XRCF)
Marshall Space Flight Center (MSFC) has maintained and operated a world-class x-ray and visible optic and detector testing facility since the mid 1970's. The XRCF as it stands today, was built in 1990 to perform the ground test and calibration of the Chandra X-ray Observatory. It includes an optically clean, thermally controlled vacuum chamber 22.9 meters (75 ft) long and 7.3 meters (24ft) in diameter; a 518 meters (1700 ft) vacuum tube connects an x-ray source to the vacuum chamber. The vacuum chamber has liquid nitrogen panels and heater panels to simulate deep space environment and to maintain accurate thermal stability.
The original purpose of the XRCF was to simulate x-ray emissions from distant celestial objects and it is the largest facility of its kind in the world. In 2005 the XRCF added 2 kw of helium refrigeration and cryogenic shrouds to test James Webb Space Telescope optics at cryogenic temperatures of 35 Kelvin (-397 degrees F), without compromising the existing x-ray testing capability. Additionally, several wave front measuring devices and a 6DoF cryo-capable optical mount were added to increase the facility capability in the visible spectrum as part of the James Webb Space Telescope mods.

ALEKS Math Placement Test
What is ALEKS Math Assessment?
ALEKS is a powerful artificial intelligence (AI)-based assessment software product the zeros in on the student's mathematical strengths and weaknesses, reports its findings, and then if necessary provides a learning module to improve the student's knowledge and skill. ALEKS will ask between 25 and 35 questions, none of which are multiple choice. Before beginning the assessment, students will complete an online tutorial so they know how to enter answers in ALEKS. The tutorial and placement may take up to 90 minutes to complete.
If students take the test remotely, they are expected to take the ALEKS placement assessment without assistance from another person or resource. Results from ALEKS will lead to placement in a mathematics course. If students complete the assessment using assistance, there is a strong chance that they will perform poorly in their mathematics course and have to pay tuition fees to retake it.

I am using random hot-deck imputation on a repeated measures dataset.
I am tempted to use Rubin's rules for pooling the results of multiple imputation, in particular for regression coefficients. Intuitively it seems the average of the coefficient estimates could be used, but I really don't have any insight about pooling the standard errors and I have not seen any literature about this (Little & Rubin's book seems to be silent on the matter, unless I have missed something)
How can I pool regression coefficient estimates and their standard errors when performing random hot-deck imputation? Pragmatic advice, theoretical justification and/or references to the literature would be most welcome.
Edit: To clarify, by "random hot deck imputation", I mean:
Hot deck imputation involves replacing missing values of one or more variables for a non-respondent (called the recipient) with observed values from a respondent (the donor) that is similar to the non-respondent with respect to characteristics observed by both cases. In some versions, the donor is selected randomly from a set of potential donors, which we call the donor pool; we call these methods random hot deck methods

Hornussen - Where the Nouss flies from the ramp and into the playing field.
At first glance, Hornussen appears to be a mixture of golf and baseball - and yet it is much more – it is a typically Swiss sport with a tradition reaching back to the 16th century.
Share contents
Thanks for your rating
In order to expel spirits it used to be the custom to hit burning logs down from the mountain and into the valley. The sport of Hornussen is supposed to have originated from this ancient tradition and is a team game played by all ages without there being a basic social structure in place.
How the game is played
The batting team has to hit the Nouss (a kind of disk or puck) as far as possible into the opponent's area. The defending team has to stop the approaching Nouss as soon as possible by using a shingle or catch board. Usually two turns are played, and each turn, each team hits once and defends once. Each turn, every single player hits twice with three attempts. A game has no set length, and it takes about three to four hours to play two bouts. The team with the smallest number of penalisation points wins – i.e. having the smallest number of failed interceptions. In addition to the team rankings, the Swiss championships and festive occasions also provide for the ranking of individual strikers.
The Hornuss
The Hornuss or Nouss was originally a disk made of wood or horn which was hit into the playing field. There are several interpretations of the meaning of the word Hornuss and all refer to the "hornet-like" buzzing sound made by the Nouss. Measurements taken by the Biomechanical Institute at the ETH Zurich have shown that the Hornuss can reach speeds of up to 85 m/s (306 km/h), a cruising altitude of 50 to 70 metres and a flight range of up to 330 metres.
A betting game
When the game of Hornussen started, the losing party had to pay for afternoon refreshments after the match. Today, instead, bets are taken on the outcome, and are usually between 50 and 100 francs per game. Bets are also customary when the game is played on a friendly basis, which is why it is called a betting game. It is also common for individual players of similar skill levels to wager a beer on the number of points gained.
When Hornussen was first played, it was mainly a game for young single farmers. They met in the late summer / autumn to play on harvested fields against farmers from other villages. It is reported that such events enabled the players to pit their strength against each other and to regulate disputes between villages. Despite playful attempts at arbitration, the Hornussen games were often followed by wild brawls. The first written records of the Hornussen are found in church records from the 16th and 17th century, and the first known competitive Hornussen game took place in 1655 in Trub. In the late 19th century, a Hornussen association was formed and rules were set. In 1902, the national governing body (Eidgenössischer Hornusserverband) was founded. This national association and its regional sub-organisations organise the championships for the various leagues, the three-yearly national Hornussen festival, and the Hornussen matches at the national wrestling and Alpine festival as well as at other festivals.
Hornussen today
Hornussen is mainly played in the Mittelland cantons of Bern, Solothurn and Aargau. Hornussen enjoys popularity to this day, and despite the huge range of different sports on offer, is a great success – a success also explained by the close links between the sporting and traditional elements. In 2011 there were around 270 Hornussen groups with some 8,300 players organised in four special purpose associations and societies and affiliated with the national governing body.

ic or a hyperbolic problem, depending on the geometry of the mapping $g$.
Example: Before considering the general case, it's worth pausing to consider a simple example to illustrate where the analysis will take us: Let $\Sigma$ be the $xy$-plane and consider the two maps $f_\pm:\Sigma\to\mathbb{R}^3$ defined by $$ f_\pm = \bigl(x,y,\tfrac12(x^2\pm y^2)\bigr). $$ These have $g_\pm = \rho(f_\pm) = (1,0,x){\wedge}(0,1,\pm y)\ dx{\wedge}dy$. We want to find the immersions $f:\Sigma\to\mathbb{R}^3$ that satisfy $\rho(f)=g_\pm$. Well, such an $f$ will have to satisfy $$ df = (1,0,x)\ \xi + (0,1,\pm y)\ \eta = (\xi,\eta,\ x\xi{\pm}y\eta\ ) $$ for some $1$-forms $\xi$ and $\eta$ that satisfy $\xi\wedge\eta=dx\wedge dy$ and are such that $d(df)=0$. Now, this latter equation implies $d\xi=d\eta=d(x\xi{\pm}y\eta)=0$, and so, assuming that a local solution is defined on a simply-connected open set $U\subset\Sigma$, one can then write $\xi = dp$ and $\eta = \pm dq$ for some functions $p$ and $q$ on $U$. The remaining equations on $p$ and $q$ then become $0=d(x\xi{\pm}y\eta)=dx\wedge dp + dy\wedge dq$ and $dp\wedge dq = \pm dx\wedge dy$. This is two PDE on $p$ and $q$ that can be written as a single Monge-Ampère equation by setting $p = u_x$ and $q = u_y$ (which works because $d(p\ dx + q\ dy) = 0$) and then the remaining equation becomes $u_{xx}u_{yy}-u_{xy}^2 = \pm 1$, the classic Monge-Ampère equation. This is, of course, elliptic for $g_+$ and hyperbolic for $g_-$. (We will see how this is reflected in the general analysis below.) The general solution to $\rho(f)=g_\pm$ is then $$ f = (u_x,\ \pm u_y,\ xu_x+yu_y-u ) $$ where $u$ satisfies $u_{xx}u_{yy}-u_{xy}^2 = \pm 1$.
Now, I'm going to do the general analysis in terms of the moving frame and exterior differential systems, simply because that's the way I understand it and am most comfortable computing. Of course, one can avoid this, but I'm too lazy (and short on time) to do that now.
So fix a nondegenerate $g\in \Omega^2\bigl(\Sigma,\Lambda^2(V)\bigr)$. I'm going to define a bundle $P_g\to\Sigma$ whose elements will consist of the quadruples $(x;e_1,e_2,e_3)\in\Sigma\times V\times V\times V$ such that the $e_i$ are a basis of $V$ and, moreover, $e_1\wedge g(x) = e_2\wedge g(x) = 0$. On $P_g$, there exists a nonvanishing $2$-form $\Phi$ such that $g = e_1{\wedge}e_2\ \Phi$. This $\Phi$ is semi-basic for the projection to $\Sigma$ and hence is a multiple of any nonvanishing $2$-form on $\Sigma$ pulled up to $P_g$. Note that $P_g$ is a right $G_1$-bundle over $\Sigma$, where $G_1\subset\mathrm{GL}(3,\mathbb{R})$ is the subgroup that consists of matrices $A\in \mathrm{GL}(3,\mathbb{R})$ that are $(2,1)$-block upper triangular, i.e., $A^3_1=A^3_2=0$.
Now, one has the usual structure equations $de_a = e_b\ \eta^b_a$, which satisfy $d\eta^a_b = - \eta^a_c\wedge\eta^c_b$. (The summation convention always in force. I'll use the index ranges $1\le a,b,c \le 3$ and $1\le i,j,k \le 2$.) Since $g$ is a vector-valued $2$-form on a surface, one has $dg=0$, and expanding this using the structure equations yields $$ 0 = dg = e_1{\wedge}e_2\ \bigl(d\Phi + (\eta^1_1+\eta^2_2)\wedge\Phi\bigr) + e_3{\wedge}e_2\ \eta^3_1\wedge\Phi + e_1{\wedge}e_3\ \eta^3_2\wedge\Phi, $$ so $\eta^3_1\wedge\Phi=\eta^3_2\wedge\Phi=0$. Now, the hypothesis that $[g]:\Sigma\to\mathbb{RP}^2$ be an immersion is equivalent to $\eta^3_1{\wedge}\eta^3_2$ being nonvanishing, Consequently, $\Phi = \lambda\ \eta^3_1{\wedge}\eta^3_2$ for some nonvanishing function $\lambda$ on $P_g$. One easily computes that, for $A\in G_1$, $$ R_A^*\lambda = \left(\frac{A^3_3}{A^1_1A^2_2-A^2_1A^1_2}\right)^2\lambda, $$ so the sign of lambda is constant on the fibers of $P_g$ and the equation $\lambda=\pm1$ defines a subset $P_g'\subset P_g$ that will be a right $G_2$-bundle over $\Sigma$, where $G_2\subset G_1$ is the subgroup consisting of those $A\in G_1$ that satisfy $A^3_3 = \pm(A^1_1A^2_2-A^2_1A^1_2)$.
I'll say that $g$ is of elliptic (resp. hyperbolic) type if $\lambda = +1$ (resp. $\lambda=-1$) on $P_g'$. (The reasons for these designations will become apparent below.)
Since $\Phi = \pm \eta^3_1{\wedge}\eta^3_2$ on $P_g'$, the structure equations plus the identity $0=d\Phi + (\eta^1_1+\eta^2_2)\wedge\Phi$ now show that $(\eta^3_3-\eta^1_1-\eta^2_2)\wedge\eta^3_1{\wedge}\eta^3_2=0$, so $\eta^3_3=\eta^1_1+\eta^2_2+b^1\eta^3_1+b^2\eta^3_2$ for some functions $b^1$ and $b^2$ on $P_g'$. The structure equations now show that the equations $b^1=b^2=0$ define a $G_3$-subbundle $P_g''\subset P_g'$, where $G_3\subset G_2$ is the subgroup consisting of those $A\in G_2$ with $A^1_3=A^2_3=0$. (This is the last reduction I will need to do to complete the calculation.)
Our goal now is to find $1$-forms $\eta^1$ and $\eta^2$ on $P_g''$ satisfying the equations $$ d(e_1\ \eta^1 + e_2\ \eta^2) = 0\qquad\text{and}\qquad e_1{\wedge}e_2\ \eta^1{\wedge}\eta^2 = g = \pm e_1{\wedge}e_2\ \eta^3_1{\wedge}\eta^3_2\. $$
If we can do this, then, at least locally, $e_1\ \eta^1 + e_2\ \eta^2 = df$ for some $V$-valued function $f:\Sigma\to V$ such that $\rho(f) = g$, and this will solve our problem.
Of course, the second equation is just $\eta^1\wedge\eta^2 = \pm\ \eta^3_1{\wedge}\eta^3_2$, while using the structure equations to expand the first equation yields $$ 0 = e_1 (d\eta^1 + \

The mammalian ovary contains a vast reserve of oocytes, most of which are enclosed within preantral follicles. A Biopsy Pick-Up (BPU) method was tested to determine the feasibility of retrieving preantral follicles from mare ovaries in vivo. BPU fragments were collected from 5 to 21 yr old mares during the breeding season and processed using a tissue chopper, submitted to histological analysis or submitted to in vitro culture for 1 or 7 days. In conclusion, the BPU method is a reliable way to repeatedly harvest large numbers of viable, morphologically normal preantral follicles from living mares without affecting ovarian function or general reproductive health. Additionally, equine preantral follicles undergo development and growth when submitted to in vitro culture in α-MEM for 7 days, with some follicles maintaining morphological normality throughout. These technologies could be used in the future to enable the use of numerous oocytes present within the equine ovary to preserve genetic material or for large-scale embryo production.

When you're running a business, having reliable equipment is essential for maximizing efficiency and keeping downtime and profit loss to a minimum. Routine maintenance and reactive fixes are helpful, but knowing when your equipment is going to break down and proactively fixing it can save you time and money. Below, we'll explain what an infrared electrical inspection is and the benefits of conducting one in your facility.
What is an Infrared Electrical Inspection?
An infrared (IR) electrical equipment inspection is an examination of any electrical components or machinery utilizing IR technology to detect inefficient operation or equipment failure.
What Does It Inspect and How Does It Work?
An Infrared Electrical Inspection can be used to scan any electrical component, including wiring, connections, breakers, fuses, circuits, switches, disconnects, and more.
Malfunctioning or overloaded electrical equipment will give off more heat than normal due to increased electrical resistance. This heat can be detected and documented with the use of certified infrared imagers. Detecting electrical hot spots allows for repair or replacement of the affected equipment before failure occurs. Atlantic Testing Services uses only certified thermographers and state-of-the-art equipment to provide professional surveys in compliance with industry standards.
Below are the five most significant benefits of an IR electrical inspection:
1 – Identifies Problems Early
Excessive heat in your equipment is a clear sign that something isn't functioning correctly. IR scans can predict when and where equipment failure will occur, allowing you to repair accordingly.
2 – Reduces Downtime
IR scans work while your equipment is running, which means you won't need to shut down your business for an inspection.
3 – Keeps Testers Safe
These scans use infrared imagers s to find inefficiencies, which means the technician and your employees remain completely safe throughout the process.
4 – Improves the Effectiveness of Routine Maintenance
Routine maintenance is important, but problems detected by IR aren't always visible. An infrared inspection can help pinpoint the areas that would otherwise be missed during routine maintenance.
5 – Helps Prevent System Failure
Regular IR inspections will help ensure your equipment remains up and running, so your business can maintain efficiency and avoid being caught off guard.
Risk of Not Getting an Infrared Electrical Inspection
Neglecting to get your equipment inspected with IR can let faulty components continue to break down and fail prematurely. Infrared electrical inspections are crucial for maintaining your company's uptime and minimizing costly repairs and outages. For more information on IR inspections, or to schedule one for your business, contact one of our highly-trained professionals today.


cpath:find-gcpath ht) in which case the target is the first non-nil, non-empty, non-deleted key in ht, which must be a hash-table.
 4. An object with a finalization (see Section 10.2 Finalizations), as in (gcpath:find-gcpath f) where f is a finalization. In this case the target is the object f is a finalization for.
 5. A default object, as in (gcpath:find-gcpath). This is used after a previous invocation of find-gcpath has found a path too long to fit in the work buffer. In this case an object part way along the path is chosen as a temporary root, a path from that temporary root is displayed, and the temporary root saved to be used as the default target in a subsequent find-gcpath.
The result argument designates a vector in which the path is built. It can be omitted to get a newly-allocated vector of default size. It can be an integer, specifying the length for the newly-allocated vector. It can be a simple-vector of at least the default size which can be panified (and it will be, as part of the operation).
If the weak argument is non-nil, then the vector argument can be a non-weak vector, but will be treated as a weak vector during the path-tracing.
If the interpret argument is omitted or non-nil, then the function returns no values, but formats an interpreted display of the path. If the interpret argument is specified as nil, then no interpretation is printed, and the function returns the result vector.
Example of gcpath:find-gcpath

cg-user(22):
collected-newstuff
Macro
Package: gcpath
Arguments: ( &optional (type #()) (size 1000)) &body body
The macro evaluates body, using a weak-key hash-table to record all the objects of the designated type before evaluating the body code. After the body has been evaluated, all the objects of that type are again scanned, and those which are not in the hash-table are collected into a newly-allocated weak simple-vector which is returned as the value of the macro form.
The type to be tracked defaults to simple-vector. Another type can be designated by providing the optional type argument. type can be given as an integer in the range 1 to 255 inclusive, designating objects with that internal typecode, or as a form evaluating to a Lisp object, in which case that object's type is designated. type should not be specified as a Common Lisp type name, as that would be interpreted as designating lists or symbols. (While typecodes are not programmatically available, some are displayed in the output of (room t).)
The optional size argument specifies the initial size of the hash-table used to record existing objects. In a large application or when tracking very common object types, it can be helpful to specify a larger initial size.
One global gc is performed before the body code is evaluated, to minimize unnecessary entries in the hash-table. Several are done after the body code is evaluated, to eliminate as much transient data as possible from the set of returned objects. Thus, the newly created vector in the body of this form:
(gcpath:collected-newstuff () (make-array 10))
will not appear in the returned result vector because it will be gc'ed away before the result is constructed while it will appear in the result of this form:
(gcpath:collected-newstuff () (setq my-vec (make-array 10)))
because it will still be the value of my-vec when the form completes.
The result is very close to the newly-allocated non-transient data created while the form is executed.
In a multiprocessing environment all new data allocated by all executing threads is considered, not just the data allocated by the thread executing the collected-newstuff form.

The print subsystem requires access information for the printer. The subsystem uses the destination name when making the network connection to the printer. You supply this name to the print subsystem by using the lpadmin command. This name then becomes part of the printer configuration database. The printer access name is the name of the printer node, sometimes qualified by a port name. Port designation varies across printer vendors. You can find information about port designation in the printer documentation.
Here is the format of printer access name:
Destination names can be specified in one of three forms:
(destination) - Is resolved by locating a printer-uri-supported key/value pair for the named destination in the printers.conf or the printers configuration database. If no printer-uri-supported key is found for an entry, it's bsdaddr value is converted to printer URI form and used.
(scheme://endpoint) - Is completely resolved and specifies the protocol and communication endpoint to contact for print services. This form of destination name is useful for accessing print services outside of your system's current management domain. Since the name includes the protocol to use when contacting the print service, you can select a richer protocol than the RFC-1179 protocol.
(server:queue[:extensions]) - Is complete and resolves to an equivalent printer URI form of lpd://server/printers/queue[_TAG_] This form is being maintained for backward compatibility only. The printer URI form is the preferred replacement.
A common port designation with TCP is 9100. If the printer node name is pn1, and the printer vendor defines the port as 9100, then the printer access name is pn1:9100. To configure a printer in this case, use the following command:
lpadmin -p printer_name -o dest=pn1:9100
When you use the BSD protocol, the port designation might not be a number, but some name defined by the printer vendor, for example: xxx_parallel_1. If the printer node name is cardboard, then the printer access name is cardboard:xxx_parallel_1. To configure a printer in this case, use the following command:
lpadmin -p printer-name -o dest=cardboard:xxx_parallel_1
If there is no port designation, and the printer node name is newspaper, the printer access name is the printer node name: newspaper. To configure a printer in this case, use the following command:
lpadmin -p printer-name -o dest=newspaper

Aqu@teach – The first aquaponics curriculum to be developed specifically for university students
The results of our ERASMUS+ project have been published.
Aquaponic food production requires a broad spectrum of knowledge in order to understand and manage the processes involved. For commercial aquaponics to develop its full potential, it will require an appropriately trained workforce. Aqu@teach covers the basics of aquaponics with a focus on transferable and entrepreneurial skills.
The aquaponics curriculum can either be taught using blended learning – combining digital media and the internet with classroom formats that require the physical co-presence of the teacher and students – or as an e-learning course.
All of the Aqu@teach resources are open access. They include the e-learning modules, textbooks, module guides for students, curriculum guides for teachers, best practice guide for teaching aquaponics, and toolbox of innovative didactic practices.
Aqu@teach was devised in collaboration as an Erasmus+ Strategic Partnership for Higher Education. The projecct is described in a special edition on «Aquaponics: Circular Sustainability for Food Security» in the Journal Horticulturae:

Alexander Kellett, a KDE developer, was looking for a way to dynamically change the colours in a desktop theme, but still keep the set of colours consistent. Imagine taking a theme where the icons are predominantly blue and changing it to a red-based colour scheme.
My suggestion was to rotate the colours using the hue angle from a perceptual colour space like CIELAB. This keeps the lightness (perceptual brightness) and amount of colour unchanged while rotating the hue.
The following is an example of a colourful image rotated by its hue, and then an example of a set of ten KDE icons. The icons show how each new colour scheme is relatively consistent in appearance, and our transition around the hue axis results in a reasonably even walk around the available colours. Finally, we show a saturated chromaticity diagram rotated by its hue to better show how these colours are mapped.
The source code for performing this rotation has been made available under the MIT license.
For a better idea of where colours get rotated to, click here for some renderings and a visual description of the CIELAB hue circle.

Mooreville High School - Water Quality Sampling and Testing
November 5, 2012
Traveling all the way from north Mississippi, Adelia Wright brought her students on a two-night stay with us here at GCRL. Unfortunately, bad weather made it imposible for the group to show off their stewardship on a marine debris removal trip. However, they became experts at water quality testing. They produced extensive data by collecting samples at several locations along the coast and performing water quality tests. They also learned about mapping, GPS usage, and watersheds.

Mortar Training Blended Learning Solution
CDS Defence Support was tasked to develop a blended learning solution for the Army Mortar Training School.
CDS was tasked to develop a Blended Learning Solution (BLS) for the Army Mortar Training School. The aim of the solution was to allow students in training to use mortars to practice and develop the skills associated with map reading, calculating bearings and judging distance based on the terrain's features.
Scanning the Landscape
The solution needed to be able to generate targets randomly at a variety of distances within a set training area. The students would then be required to manually scan the landscape to identify potential targets.
The students also needed to be able to use a service prismatic compass to acquire the target's direction.
After calculating the bearing, the students would have to accurately identify target locations on the map.
Making Corrections Based on a Missed Shot
The students would have to have the ability to make adjustments and re-engage the target an unlimited number of times.
Working closely with a number of SMEs, CDS interpreted the requirements and developed an application that delivered the required features whilst adding additional benefits at every stage.
Our BLS allows both the students and the instructors to have sight of the students' process of acquiring and engaging a target.
The students navigate round a geographically accurate virtual environment, based on a known training area, where a number of randomly generated targets appear at different distances. Once a target is identified, the student must use the skills learned in practical training to make the correct calculations and effectively engage the target.
Complex background algorithms accurately simulate, in real time, the characteristics of a mortar round's velocity, trajectory (fall of shot) and the time of flight. The student can then watch the round hit or miss the target and can make multiple corrections to re-adjust and re-engage until a Fire for Effect (FFE) order can be given.
This solution can also be integrated with Learning Management Systems.
Other optional features include:
- Encryption to allow for off-site use.
- Secure data link to record students' information including usage and strike rate.
- Auditable confirmation of training and competency.
A BLS has many advantages including:
- Students can be trained for multiple-operational scenarios and terrains prior to deployment.
- 24/7 access to training – no down-time due to adverse weather conditions or range day losses.
- Costs are reduced by negating the need for additional range time, ammunition and coaching/training staff.
- The application has cross-platform functionality and is able to run on Android, iOS and other similar operating systems.
- The Mortar Training can be digitally tailored to suit any combination of ammunition including illumination, smoke rounds and differing terrains.
In addition to the Mortar Training, CDS has also developed a 7.62mm General Purpose Machine Gun BLS. This unique tool presents the students with a geographically accurate virtual map, a protractor, a series of range tables and issue fire control data.
The students will identify and process the 8 figure grid reference number, the altitude above sea level, the bearing and distance and finally use this information to calculate the elevation adjustments required prior to engaging the target.

Lattix Architecture Analysis for Java provides an architecture solution that helps software development teams understand, define (refactor) and control their codebases. It is the most comprehensive solution for analyzing the architecture of your Java applications allowing you to create a Dependency Structure Matrix from your jar, ear, war, apk, aar files, and java classes to understand the interrelationships (dependencies) between them at any level (jars, packages, classes, interfaces, methods, data members, etc.) Understanding the dependencies allows you to create a clean architecture. A clean architecture has a modular hierarchy and is enforced with automatic design rule violations. The benefits are lower code complexity, faster time-to-market, lower cost, and fewer defects.
This example is the Dependency Structure Matrix of Ant, the popular Java build tool:

Recent research published in the American Ceramic Society's Bulletin magazine has shown that a particular borate glass composition can be used to form cottony glass fibers to mimic the structure of fibrin, in turn supporting the wound healing process.
According to a related report by Medical News Today, bioglass materials are not new to the medical field but thus far they have been formed from a silica-based glass composition for use in hard tissue regeneration, such as bone repair. However, co-developers Steve Jung, PhD, and Delbert Day, a professor, both from the Missouri University of Science and Technology, noted from in vitro studies that bioactive glasses containing boron reacted to body fluids faster than silicate glasses. This led them to wonder whether a different bioactive glass material could be used for soft tissue repair and regeneration.
The researchers also found that lithium borate glasses showed beneficial effects against bacteria such as E. coli, salmonella and staphylococcus microbes. Further, the materials were rich in calcium; and as Jung commented in the report, previous investigators have found calcium to be important for wound healing as it appears to assist in the migration of epidermal cells to help regulate the healing process.
Besides the material's composition, its structure was important to consider as it would need to provide a "scaffold." The researchers believed that if the material that could mimic the microstructure of fibrin, it might trap blood platelets and allow the formation of a wound cover that could support the healing process. Therefore, a particular borate glass composition called 13-93B3 glass was chosen and Mo-Sci, a company founded by Day, formed it into cottony glass fibers 300 nm to 5 μm in diameter. After animal tests showed no adverse effects, the company obtained a license from the university and produced the borate glass material, named "DermaFuse."
Peggy Taylor, a registered nurse at the Phelps County Regional Medical Center (PCRMC) in Rolla, Missouri, reportedly tested the material by applying pads of the borate glass nanofibers to the wounds of 12 venous stasis volunteers, which sped up the healing process of their long-term wounds. Taylor noted, in a Science Daily report, that the pads were easy to apply and could be formed to any shape needed. Interestingly, she also observed that over time, the glass fibers seemed to disappear—a phenomenon that has been observed with other bioglasses.
Taylor acknowledged that while the wounds would have probably healed under her care without the glass material, they would have required expensive vacuum-assisted healing systems. In addition, the glass fibers seemed to drastically reduce scarring. The next step is expanded human trials this summer, which reportedly will be conducted in partnership with the Center for Wound Healing and Tissue Regeneration at the University of Illinois at Chicago.
This material could potentially be used by battlefield medics or emergency medical technicians to provide first aid with these glass fibers that simultaneously slow bleeding, fight bacteria (and other sources of infection) and stimulate the body's natural healing mechanisms. In addition, it could be used to treat diabetics suffering from hard-to-heal wounds. Beyond health benefits, the wound healing and reduced scarring mechanisms are interesting for the cosmetics industry and suggest new concepts relevant to skin care and anti-aging treatments in general.

Florist on a bike: a pedalling petal peddler
I was just up at a resort on Georgian Bay where I got some exercise with a pedal boat -- or, as the spelling-challenged resort called it, a peddle boat. Pedal and peddle are two different words. Where feet are involved with pushing a lever (as in a bicycle, or an organ, piano, sewing machine, etc.) the spelling is "pedal". It derives from a Latin word meaning "foot", pes, which became pedwhen it combined with a suffix. It also turns up in "pedestrian".
When you're talking about selling something, possibly door-to-door, often drugs, or even more notionally when you are trying to promote an idea, the word and spelling you want is peddle. This seems to be what we call a "back-formation" from the noun "pedlar" (usually spelled "peddler" in North America). Unfortunately we don't know the origin of this word for sure.
For speakers of North American English, there is a third word in this series of homophones (words that sound the same but are spelled differently): petal, the part of a flower (which comes quite boringly from the Latin petalum meaning the same thing).
So, how to keep these straight if you keep mixing them up?
Here are a couple of mnemonics (memory devices) I have thought up. Do let me know if they help!
Pedal (foot thing). Think bicycles (the thing that comes first to most people's minds when they think about pedals). Have a really vivid image in your brain of Albert Einstein riding a bicycle (or if you know someone called Al, you can put him on the bike in your mental image). Slap a T-shirt on Einstein with his name, AL, in big letters on the back. Those of you who like acronyms can try the following Tour de France-inspired one: Practically Every Day Armstrong Leads: P.E.D.A.L.
With either of these mnemonics you associate "-al" with bicycles, and thus with other foot-controlled things.
Peddle (sell). We don't really have old-fashioned peddlers with their vans full of assorted goods anymore. When we use the verb "peddle", we're more likely to be speaking of someone peddling heroin. Who peddles? Drug dealers. Perhaps this alliterative compound with a double D will help you remember that "peddle" is not for bikes, but it is for selling (although it probably won't be an approved mnemonic for use in Ontario schools).
Petal (flower). Think of other flower-related words: stem, plant, leaf, flower, (if you're really into botany or want to show off, you'll know stamen and pistil, anther, calyx and styles as well, but if you can spell them already you're probably not having difficulty with "petal"). Do you see a letter D anywhere? Nope! And in fact, what letter does turn up in a lot of these flower words? Yes! T! So, if we're talking flowers, it's petal with a T!
Now, what about that word "soft-pedal" (or is it "soft-peddle"?) meaning "tone down, go easy on"? It is in fact "soft-pedal", the image being of a pianist using the pedal that reduces the volume of the note being played.
As for the resort, a further complication in the case of those boats that you propel with pedals is that they are also called "paddle boats" (presumably because you paddle about in them). In most North American pronunciations, short e's and short a's are very close together, so that "paddle" is a very close homophone of pedal, peddle, and petal.
But whatever they are, they aren't "peddle boats"!
 1. Hi Aunt Kate!
 Thanks for checking out my blog! I very much like your blog, this particular post involving pedal boats (not "peddle" boats) caught my eye because my mom was telling me about a particular mishap she recently had with just such a pedal boat - and I believe you were witness to this mishap? :-)
 I hope all is well, I'm now off to check out your ballet tour blog.
 2. If your mother had been less charitable, she would have mentioned that I was not just the witness but the CAUSE of her mishap with the pedal/paddle boat!
 3. If you are talking about the person riding a bike or a paddle boat, would that be a pedlar or a pedaler? We want to name my dad's paddle boat "Papa's Pedaler". Would that be correct or would it be "Papa's Pedlar"? The grandkids would either be "Papa's Pedalers" or "Papa's Pedlars". Thanks for your help!! I at least know that they aren't "Papa's Peddlers" (which is how we originally were going to spell it!!)

and "no" in the latter.
 - Entropy Approximation (EA): Now we're promised that the entropy of the circuit's output distribution is either at least k+1 or at most k-1. The problem is to output "yes" in the former case and "no" in the latter.
NIPZK can be defined similarly.
There is an oracle separating NISZK from PP [BCHTV17].
NISZKh: NISZK With Limited Help
The non-interactive analogue of SZKh.
Defined in [BG03], where the following was also shown:
 - NISZKh contains NISZK and is contained in SZK.
 - Graph Isomorphism is in NISZKh.
 - The following problem is complete for NISZKh: Given two functions from {0,1}n to {0,1}n (specified by circuits), decide whether their ranges are almost equal or almost disjoint, given that one of these is the case.
The quantum lower bound for the set comparison problem in [Aar02] implies an oracle relative to which NISZKh is not in BQP.
NL: Nondeterministic Logarithmic-Space
Has the same relation to L as NP does to P.
In a breakthrough result, was shown to equal coNL [Imm88] [Sze87]. (Though contrast to mNL.)
Is contained in LOGCFL [Sud78], as well as NC2.
Is contained in UL/poly [RA00].
Deciding whether a bipartite graph has a perfect matching is hard for NL [KUW86].
NL can be defined in a logical formalism as SO(krom) and also as FO(tc), reachability in directed graph is NL-Complete under FO-reduction.
NL/poly: Nonuniform NL
Has the same relation to NL as P/poly does to P.
Is contained in ⊕L/poly [GW96], as well as SAC1.
Equals UL/poly [RA00].
NLO: NL Optimization Problems
The class of optimization problems which can be solved in nondeterministic logspace.
Defined in [TAN07] as the logspace equivalent of NPO, where it is shown that the various logspace approximation classes form a hierarchy iff LNL.
As with the definition of NPO in [ACG+99], NLO is defined as a class of "structured" problems, comprising both a "solution relation" (indicating which solutions are acceptable for a given input) and a "measure function" (computing the value of each solution). The equivalent "unstructured" class is OptL. See [TAN07] for discussion.
NLOG: NL With Nondeterministic Oracle Tape
Same as NL -- but if there's an oracle, then NLOG can make queries nondeterministically on a polynomial-size, one-way oracle tape. (NL, by contrast, can use nondeterministic transitions only on the worktape; oracle queries have to be deterministic.)
See [LL76] or [HCK+88] for more information.
Although NLOG is contained in P, there exists an oracle relative to which that is not the case. This illustrates that care is needed when defining oracle access mechanisms.
NLIN: Nondeterministic LIN
Has the same relation to LIN as NP does to P.
NLT: Nearly Linear Time
Class of functions computable in nearly linear time n(log n)O(1) on deterministic random access machines.
Defined in [GS89].
See also QL.
NMCL: Nondeterministic Moore-Crutchfield Languages
Alternative name for QRL. Named such in Abuzer Yakaryilmaz, A. C. Cem Say. Languages recognized by nondeterministic quantum finite automata..
Not to be confused with the similar NQL.
NNC(f(n)): NC with O(f(n)) nondeterministic gates
Same as NC, but with O(f(n)) nondeterministic gates. A nondeterministic gate has no inputs and a single output bit.
Defined in [Wol94], where the author proves various inclusions, including but not limited to NNC(poly(n))=NP, NNC(log(n))=NC, and NNC(polylog)⊆DSPACE(polylog).
NNLT: Nondeterministic Nearly Linear Time
Class of functions computable in nearly linear time n(log n)O(1) on nondeterministic random access machines. Equals NQL [GS89].
Defined in [GS89].
NONE: The Empty Class
The class that does not contain any languages. (It might not surprise you that I put this one in at the suggestion of a mathematician...)
Is the opposite of ALL, but does not equal the complement coALL = ALL.
Is closed under polynomial-time Turing reductions :-).
NP: Nondeterministic Polynomial-Time
The class of dashed hopes and idle dreams.
More formally: an "NP machine" is a nondeterministic polynomial-time Turing machine.
Then NP is the class of decision problems solvable by an NP machine such that
 1. If the answer is "yes," at least one computation path accepts.
 2. If the answer is "no," all computation paths reject.
Equivalently, NP is the class of decision problems such that, if the answer is "yes," then there is a proof of this fact, of length polynomial in the size of the input, that can be verified in P (i.e. by a deterministic polynomial-time algorithm). On the other hand, if the answer is "no," then the algorithm must declare invalid any purported proof that the answer is "yes."
For example, the SAT problem is to decide whether a given Boolean formula has any satisfying truth assignments. SAT is in NP, since a "yes" answer can be proved by just exhibiting a satisfying assignment.
A decision problem is NP-complete if (1) it is in NP, and (2) any problem in NP can be reduced to it (under some notion of reduction). The class of NP-complete problems is sometimes called NPC.
That NP-complete problems exist is immediate from the definition. The seminal result of Cook [Coo71], Karp [Kar72], and Levin [Lev73] is that many natural problems (that have nothing to do with Turing machines) are NP-complete.
The first such problem to be shown NP-complete was SAT [Coo71]. Other classic NP-complete problems include:
 - 3-Colorability: Given a graph, can each vertex be colored red, green, or blue so that no two neighboring vertices have the same color?
 - Hamiltonian Cycle: Given a graph, is there a cycle that visits each vertex exactly once?
 - Traveling Salesperson: Given a set of n cities, and the distance between each pair of cities, is there a route that visits each city exactly once before returning to the starting city, and has length at most T?
 - Maximum Clique: Given a graph, are there k vertices all of which are neighbors of each other?
 - Subset Sum: Given a collection of integers, is there a subset of the integers that sums to exactly x?
For many, many more NP-complete problems, see [GJ79].
NP contains P. I've discovered a marvelous proof that NP and P are unequal, but this web page is too small to contain it. Too bad, since otherwise I'd be eligible for $1,000,000 [CMI00].
There exists an oracle relative to which P and NP are unequal [BGS75]. Indeed, P and NP are unequal relative to a random oracle with probability 1 [BG81] (see [AFM01] for a novel take on this result). Though random oracle results are not always indicative about the unrelativized case [CCG+94].
There even exists an oracle relative to which the P versus NP problem is outside the usual axioms of set theory [HH76].
If we restrict to monotone classes, mP is strictly contained in mNP [Raz85].
Perhaps the most important insight anyone has had into P versus NP is to be found in [RR97]. There the authors show that no 'natural proof' can separate P from NP (or more precisely, place NP outside of P/poly), unless secure pseudorandom generators do not exist. A proof is 'natural' if it satisfies two conditions called constructivity and largeness; essentially all lower bound techniques known to date satisfy these conditions. To obtain unnatural proof techniques, some people suspect we need to relate P versus NP to heavy-duty 'traditional' mathematics, for instance algebraic geometry. See [MS02] (and the survey article [Reg02]) for a development of this point of view.
For more on P versus NP (circa 1992) see [Sip92]. For an opinion poll, see [Gas02].
If P equals NP, then NP equals its complement coNP. Whether NP equals coNP is also open. NP and coNP can be extended to the polynomial hierarchy PH.
The set of decision problems in NP, but not in P or NPC, is sometimes called NPI. If P does not equal NP then NPI is nonempty [Lad75].
Probabilistic generalizations of NP include MA and AM. If NP is in coAM (or BPP) then PH collapses to Σ2P [BHZ87].
PH also collapses to Σ2P if NP is in P/poly [KL82].
There exist oracles relative to which NP is not in BQP [BBB+97].
An alternate characterization is NP = PC

Essentially, this attribute tells the shell to attach various attributes to the parameters of a function, such as making the parameter mandatory, tagging it for pipeline parameter binding, or specifying various input validation rules for the parameter's values. By using CmdletBinding() in your function, you can also declare support for the -whatif and -confirm switches, among other capabilities.

Sediment Retention Fiber Rolls (SRFRs)
What are Sediment Retention Fiber Rolls?
Site engineers, consultants, regulatory agencies, earthwork and seeding contractors, and other professionals within the construction industry often are faced with challenges posed by land, nature and weather. Special care must be taken to prevent soil erosion and sedimentation in receiving waters.
Sediment Retention Fiber Rolls (SRFRs) can help provide this special care. SRFRs are also known as "wattles." SRFRs slow and spread runoff, reducing sediment entering retention ponds, lakes and other water bodies.
The Erosion Control Technology Council's approved definition of a sediment retention fiber roll is:A sediment retention fiber roll is a manufactured 3-dimensional device of a specified filler material encapsulated within a flexible containment material utilized in sediment and flow control applications.


ICU Processes and Procedures
ICU Release Version Number Policy
ICU version number consists of up to four digits separated by dot.
 - First two digits are used for major release number. Major release numbers for C and J are always synchronized.
 - Even number at the second digit indicates an official release (e.g. 4.2)
 - Odd number at the second digit indicates a development release (e.g. 4.3.1) for next major release.
 - Third digit in an official release number indicates a maintenance update which is applicable to both C and J.
 - Incremented only when C and J have common changes, such as CLDR update.
 - For example, CLDR 1.7.1 changes are integrated into ICU4C 4.2.1 and ICU4J 4.2.1.
 - Third digit in a development release number indicates a milestone
 - ICU4C 4.3.1 -> ICU4C 4.4 development milestone 1
 - Fourth digit in an official release number indicates a maintenance update only applicable to either C or J.
 - For example, ICU4C resolved some platform specific build issues and no equivalent changes in J.
Ticket Life Cycle
Here is a description of the life cycle of an ICU Trac ticket, a feature request or a bug report, from initial submittal through implementation and review to release.
Feature Proposals and Design
 1. All API design proposals (for any additions and changes) must be proposed on the icu-design mailing list.
 2. The proposal email itself must include: (See the template subpage)
 1. The proposed (new or changed) API signature(s)
 2. A Trac ticket number
 3. A Suggested API reviewer
 4. A deadline for comments (usually one week from proposal).
 3. Background information in the proposal can be helpful if the topic is complex. If there is a lot of information, write a design doc.
 4. The API signature must be reviewed by someone before submitting, and the reviewer must reply to the posting.
 5. In the ICU core team meeting, we have a regular agenda item to confirm recent API proposals (before or after code submission). Here we confirm that someone has reviewed it and no one objects.
 6. New/changed API that is discovered to not have proposal is withdrawn at or before the API Freeze milestone.
 7. We will try to write a tool to find API additions. The idea is to add a text file to the repository with expected additions/changes, and to check the actual set of APIs against that.
 8. There should not be major API additions after the API Slush milestone. Small additions (for example, new methods on existing classes) should be ok.
 9. Major functionality/new API or disruptive changes need to be implemented on a branch. The API there must be reviewed and confirmed before merging it to the trunk.
ICU Coding Style Guidelines
The ICU coding guidelines are described in the user guide at
ICU Release Process
The release task list contains the list of things to complete when releasing a a new version of the ICU libraries.
Design Documents
Design Documents for various ICU services are maintained in the following locations:

Does tortellini have to be boiled?
1. Don't boil it! Toss refrigerated tortellini with a lot of sauce (the ratio should be 1 part ravioli to 2 parts sauce), then throw everything into a baking dish.
Can you eat tortellini raw?
Can you eat tortellini without cooking it? As with any uncooked food, there is a chance of cross contamination; the cheese can have listeria, the pork or beef e. Coli, the raw egg could have Salmonella. You take your chances eating it raw.
Why does tortellini float?
Only stuffed pasta like ravioli, tortellini, or mezzelune will float to the surface during cooking. This happens because the air inside them expands when heated, making the pasta noodles less dense than the water. When the noodles float, that doesn't necessarily mean that they're done.
Can you cook raw pasta in sauce?
You can cook pasta in the sauce, but you need to make sure that you're adding more liquid for the pasta to absorb. To do this, dilute the sauce until it covers the dry pasta, then continue to add more liquid whenever the pasta dries out.
Can you cook dry tortellini in sauce?
Dried "tortellini alla carne" (with meat) should be cooked in broth/stock or boiling salted water for 15 – 18 mins. My Sicilian brother in law recommends stock. With all pastas, you'll want to bring your water to a boil and then back off to a relative simmer before adding your pasta.
Is tortellini pre cooked?
Is tortellini already cooked? The filling is almost always precooked so it is not relevant unless you are pregnant. … The interior can be ham and that's fine, if you have a meat tortellini is a mixture of various types of meat such as pork and raw pork is not suitable.
Is tortellini always stuffed?
Traditionally they are stuffed with a mix of meat (pork loin, raw prosciutto, mortadella), Parmigiano Reggiano cheese, egg and nutmeg and served in capon broth (in brodo di cappone).
|The distinctive shape of tortellini|
|Alternative names||Belly button|
|Cookbook: Tortellini Media: Tortellini|
What happens if you overcook tortellini?
The starch can also be digested in a gradual manner, which prevents blood sugar spikes. Raw pasta is not easy to digest because the body's digestive enzymes cannot adhere to it, whereas overcooked pasta tends to form a sticky dough in the digestive tract, which blocks digestion.
Is tortellini safe for pregnancy?
If your ricotta cheese is made from pasteurized milk, there's no harm in including it in your diet during pregnancy.


text: When considering the Lagrange point 1 in the Sun/Earth system, Does Lagrange Point 1 have any orbital velocity around Earth? I suspect a body at L1 has no orbital velocity around earth. But consider the earth's position 6months later when it is opposite the sun. The Lagrange point would also have moved to the opposite side of the earth. This would suggest the orbital period of a body at L1 around the earth would be one year. So back to my original question: Does Lagrange Point 1 have any orbital velocity around Earth?


How to observe the elusive resonances in H or D + H2 → H2 or HD + H reactive scattering
William H. Miller, John Z.H. Zhang
Research output: Contribution to journalReview articlepeer-review
Short-lived collision complexes in H or D + H2 (v = j = 0) → H2 or HD (v′, j′) + H reactive scattering give rise to broad resonance structure. Though this structure is not observable in the energy dependence of the integral cross section, it is readily seen in the energy dependence in the differential cross section σ(θ,E), as a peak along a line in the E-θ plane. The equation of this resonance line is E = Er(J(θ)), where Er(J) is the resonance energy as a function of total angular momentum J (i.e., the rotational quantum number of the complex) and J(θ) is the inverse function of θ(J), the effective classical deflection function for the transition. Observation of this resonance structure requires cross sections to individual final (v′, j′) states; it is quenched by summing over j′. It is even more enhanced in cross sections to specific final m′ states with m′ ≠ 0. (m′ is the helicity of the final state, the projection of the final diatomic molecule rotational angular momentum onto the final relative translational velocity vector.) The results reported are all from rigorous three-dimensional quantum mechanical reactive scattering calculations for these cross sections.

Dressing of Stone is the working of quarried stone into the shape and size required for use. This can be necessary as stones obtained from quarrying generally do not have the exact required dimensions or finish.
Stone dressing can be carried out using a variety of tools depending upon the finish required. Rough finishes may be achieved using quarry hammers and chisels, whereas rubbed or polished finishes may be achieved by rubbing or grinding a cut stone surface, either by hand (using sand and water, pumice stone, and so on), or by machine.
There are several types of finish that can be achieved by stone dressing:
- Axed: Hard stones such as granite are dressed using a stone axe.
- Boasted: A boaster is used to create parallel horizontal, vertical or inclined lines.
- Combed: A steel comb with sharp teeth is dragged in all directions across the surface of soft stones.
- Circular: Predominantly used for columns, circular finished stones are made into a rounded shape.
- Chisel-drafted margins: A chisel is used on stones forming uniform joints to create pitched, square or chamfered margins.
- Furrowed: The middle portion of the stone projects from the sides by around 15 mm, and deep grooves made across it.
- Moulded: Stones are moulded into decorative strips of various shapes.
- Polished: Usually for marbles, granites and so on.
- Punched: A machine depresses the stone surface creating hollows and ridges.
- Reticulated: A margin is left around the surface, and irregular shapes formed in the finish.
- Rusticated: A rough or patterned surface is cut into the visible face of masonry blocks.
- Scrabbling: Irregular projections are removed using a scrabbling hammer leaving a rough finish.
- Sunk: The original surface is depressed into wide grooves, marks, and so on.
- Vermiculated: Similar to reticulated but the shapes are curved, giving a 'worm-eaten' aesthetic.

The team has developed specialised software, which can produce theoretical ride dynamic performance predictions for any ride or given track profile.
Thereafter using state-of the-art technology and sophisticated engineering solutions, the accelerations (g-forces) can be measured on the ride and compared to the theoretical results. The engineers use their expertise in this area of amusement attraction engineering to identify problems with track profiles and offer suitable engineering solutions to improve dynamic performance. In addition, the software can be used together with the team's structural engineering expertise to undertake track design, and has been used in the development of rides such as Thunder Coaster (Tusenfryd, Norway) and Antelope (Gulliver's World, UK).
Acceleration measurement is a useful tool in monitoring the ride dynamic performance as the ride ages; this is particularly useful on timber roller coasters. Dynamic performance measurement and analysis services can be incorporated into the Annual Inspections or as a stand-alone service.


How to Add and Delete Users on Ubuntu 16.04
Introduction
One of the most basic tasks that you should know how to do on a fresh Linux server is add and remove users. When you create a new system, you are often (such as on DigitalOcean Droplets) only given the root account by default.
While running as the root user gives you a lot of power and flexibility, it is also dangerous and can be destructive. It is almost always a better idea to add an additional, unprivileged user to do common tasks. You also should create additional accounts for any other users you may have on your system. Each user should have a different account.
You can still acquire administrator privileges when you need them through a mechanism called sudo. In this guide we will cover how to create user accounts, assign sudo privileges, and delete users.
How To Add a User
If you are signed in as the root user, you can create a new user at any time by typing:
 1. adduser newuser
If you are signed in as a non-root user who has been given sudo privileges, as demonstrated in the initial server setup guide, you can add a new user by typing:
 1. sudo adduser newuser
Either way, you will be asked a series of questions. The procedure will be:
 - Assign and confirm a password for the new user
 - Enter any additional information about the new user. This is entirely optional and can be skipped by hitting Enter if you don't wish to utilize these fields.
 - Finally, you'll be asked to confirm that the information you provided was correct. Enter Y to continue.
Your new user is now ready for use! You can now log in using the password you set up.
Note: Continue if you need your new user to have access to administrative functionality.
How To Grant a User Sudo Privileges
If your new user should have the ability to execute commands with root (administrative) privileges, you will need to give the new user access to sudo. Let's examine two approaches to this problem: Adding the user to a pre-defined sudo user group, and specifying privileges on a per-user basis in sudo's configuration.
Add the New User to the Sudo Group
By default, sudo on Ubuntu 16.04 systems is configured to extend full privileges to any user in the sudo group.
You can see what groups your new user is in with the groups command:
 1. groups newuser
Output
newuser : newuser
By default, a new user is only in their own group, which is created at the time of account creation, and shares a name with the user. In order to add the user to a new group, we can use the usermod command:
 1. usermod -aG sudo newuser
The -aG option here tells usermod to add the user to the listed groups.
Test Your User's Sudo Privileges
Now, your new user is able to execute commands with administrative privileges.
When signed in as the new user, you can execute commands as your regular user by typing commands as normal:
 1. some_command
You can execute the same command with administrative privileges by typing sudo ahead of the command:
 1. sudo some_command
You will be prompted to enter the password of the regular user account you are signed in as.
Specifying Explicit User Privileges in /etc/sudoers
As an alternative to putting your user in the sudo group, you can use the visudo command, which opens a configuration file called /etc/sudoers in the system's default editor, and explicitly specify privileges on a per-user basis.
Using visudo is the only recommended way to make changes to /etc/sudoers, because it locks the file against multiple simultaneous edits and performs a sanity check on its contents before overwriting the file. This helps to prevent a situation where you misconfigure sudo and are prevented from fixing the problem because you have lost sudo privileges.
If you are currently signed in as root, type:
 1. visudo
If you are signed in using a non-root user with sudo privileges, type:
 1. sudo visudo
Traditionally, visudo opened /etc/sudoers in the vi editor, which can be confusing for inexperienced users. By default on new Ubuntu installations, it should instead use nano, which provides a more familiar text editing experience. Use the arrow keys to move the cursor, and search for the line that looks like this:
/etc/sudoers
root ALL=(ALL:ALL) ALL
Below this line, copy the format you see here, changing only the word "root" to reference the new user that you would like to give sudo privileges to:
/etc/sudoers
root ALL=(ALL:ALL) ALL
newuser ALL=(ALL:ALL) ALL
You should add a new line like this for each user that should be given full sudo privileges. When you are finished, you can save and close the file by hitting Ctrl-X, followed by Y, and then Enter to confirm.
How To Delete a User
In the event that you no longer need a user, it is best to delete the old account.
You can delete the user itself, without deleting any of their files, by typing this as root:
 1. deluser newuser
If you are signed in as another non-root user with sudo privileges, you could instead type:
 1. sudo deluser newuser
If, instead, you want to delete the user's home directory when the user is deleted, you can issue the following command as root:
 1. deluser --remove-home newuser
If you're running this as a non-root user with sudo privileges, you would instead type:
 1. sudo deluser --remove-home newuser
If you had previously configured sudo privileges for the user you deleted, you may want to remove the relevant line again by typing:
 1. visudo
Or use this if you are a non-root user with sudo privileges:
 1. sudo visudo
root ALL=(ALL:ALL) ALL
newuser ALL=(ALL:ALL) ALL # DELETE THIS LINE
This will prevent a new user created with the same name from being accidentally given sudo privileges.
Conclusion
You should now have a fairly good handle on how to add and remove users from your Ubuntu 16.04 system. Effective user management will allow you to separate users and give them only the access that they are required to do their job.

Experimental characterization and performance evaluation of geothermal grouting materials subjected to heating–cooling cycles
EstadísticasView Usage Statistics
Full recordShow full item record
AuthorIndacoechea Vega, Irune; Pascual Muñoz, Pablo; Castro Fresno, Daniel; Calzada Pérez, Miguel Ángel
In recent years, the increasing rise in environmental awareness among energy consumers has led to an increasing use of renewable energies such as the geothermal energy. An important role in the efficient exploitation of the geothermal resource is played by the grouting material placed in the borehole between the pipes and the ground. Actually, the use of proper grouts is essential to provide an effective heat transfer between the ground and the heat carrier fluid in the pipes, and also to comply with the mechanical and environmental demands. However, when it comes to the construction of the GHP installations, the grout is especially required to be easy to work with (workable) and for this reason more water than required is sometimes added. In order to assess the suitability of grouting materials with significant water/solid ratios, the thermal conductivity, mechanical strength and permeability of five different grouts and grout–pipe specimens were measured for their laboratory characterization. In addition, the grouts were subjected to heating and cooling cycles to evaluate their durability with time in terms of the potential degradation of the materials and the loss of quality of the grout–pipe interface. According to the results obtained, the grouts here tested are appropriate for most of the geothermal heat pump installations, especially for those with low to medium ground thermal properties.

What's Your Definition Of An Informatics Pharmacist?
For pharmacists who have transitioned into this area, most would agree that the industry has not yet settled on an accepted definition. Although ASHP has defined what they feel an Informatics Pharmacist is, there's not necessarily consistency in terms of how it's used to describe the positions that are being created within hospitals across the country.
Hospitals may use the ASHP definition to create a position description for a newly created role within their pharmacy, but inevitably the description will be based upon tasks that the department and organization need to be performed within the new position. It's at this point that the extra tasks that don't seem to fall neatly into any position are sometimes included in the position being created.
[eBook: How Pharmacy Informatics are Evolving to Improve Patient Care]
The bottom line is, there are no common definitions that separate the two. At this point within the industry, there's no standard that I've seen accepted broadly. Healthcare organizations are defining the skill and knowledge that need to be performed by someone in the pharmacy based on the technology and software that the pharmacy uses. The organization then decides if that person is better based in the pharmacy or the IT department.
In many organizations, this is influenced by which departments have the money for the position, or which department will have the ultimate responsibility for either implementing or supporting the technology once it's been installed. The two are really defined by the responsibilities that are assigned to the specific positions within the organization. What I then find is that if the position resides in the pharmacy, then you have an Informatics Pharmacist; if the position resides in the IT department, then you have an IT Pharmacist.
Below are responses to this question from our podcast series.
In your opinion, what's the difference between an IT Pharmacist and an Informatics Pharmacist?
Informatics Pharmacist
"In my mind, an informatics pharmacist specializes or is knowledgeable in the total medication process, from ordering to administration, and is responsible for effective process design, development, and implementation of the Electronic Medical Record and Clinical Decision Support. The informatics pharmacist should support pharmacists, physicians, nurses, and other clinicians as the resource for requests related to PharmNet, PowerChart, Discern rule changes and additions." — Tom Zogiab
"The informatics pharmacist, on the other hand, is more of a specialist who turns that pharmacy data into information. What I mean by that is, he/she will do an analysis of the pharmacy data, the clinical data, the cost data, and that type of functional data to improve clinical outcome, cost control and, ultimately, system optimization. One is more of a product specialist and the other takes that data and turns it into useful information." — Dave Wolfe
"When I hear the term Informatics Pharmacist, I think of a clinically trained pharmacist using that knowledge to improve information systems as they relate to the medication-use process." — Ron Burnett
"The informaticists do the same as the IT pharmacists but are more deeply involved in how systems are integrating with one another and how to use data between systems to help their fellow pharmacists up on the floors or in the main pharmacy to be able to do some different things." — Dave Stansbury
IT Pharmacist
"The IT Pharmacist is responsible for the technical aspects resulting from the information acquired from the informatics pharmacist and attempting to give the informatics pharmacist a working model of their request or vision of their electronic process." — Tom Zogiab
"I view an IT Pharmacist as a functional expert who understands the implementation, the maintenance, and the workflow of the pharmacy system, and how they function and interface in other systems." — Dave Wolfe
"When I hear the term IT Pharmacist, I think of a pharmacist working in the IT department as an analyst, who may or may not use a lot of their clinical background. " — Ron Burnett
"The IT pharmacist is more the IT person in the pharmacy who is doing the day-to-day maintenance, upgrading systems, and a bit of interface." — Dave Stansbury
"In the purest sense of the form, the informatics is about collecting, analyzing, pushing, and pulling data, and information technology is more about the hardware and the software, focusing more on how the operational things work inside of technology. If you look closely, those terms are really interchangeable inside a pharmacy. There's no really great definition or differentiation between the two, and that's indicative if you look at ASHP: the name of their section is the ASHP section for pharmacy informatics and technology. And if you look at job descriptions, they're all over the board. Honestly, those two terms currently are interchangeable. I think the job, in itself, is in its infancy and so, as it continues to grow, I don't know if those are eventually going to be separated back out or not. That's currently how I see the difference and similarities between those two terms. So if you're talking to somebody and you say informatics pharmacist or IT pharmacist, you're basically talking about the same person." — Jerry Fahrni

Motion-correlated flow distortion and wave-induced biases in air–sea flux measurements from ships
- 1School of Earth and Environment, University of Leeds, Leeds, UK
- 2National Oceanography Centre, Southampton, UK
- anow at: Centre for Applied Geosciences, University of Tübingen, Germany
Abstract. Direct measurements of the turbulent air–sea fluxes of momentum, heat, moisture and gases are often made using sensors mounted on ships. Ship-based turbulent wind measurements are corrected for platform motion using well established techniques, but biases at scales associated with wave and platform motion are often still apparent in the flux measurements. It has been uncertain whether this signal is due to time-varying distortion of the air flow over the platform or to wind–wave interactions impacting the turbulence. Methods for removing such motion-scale biases from scalar measurements have previously been published but their application to momentum flux measurements remains controversial. Here we show that the measured motion-scale bias has a dependence on the horizontal ship velocity and that a correction for it reduces the dependence of the measured momentum flux on the orientation of the ship to the wind. We conclude that the bias is due to experimental error and that time-varying motion-dependent flow distortion is the likely source.
