Green Seal Standard for Restaurants Unveiled

Green lodging certifier Green Seal has extended its ecolabeling program to restaurants and foodservice establishments that reduce their environmental impacts, with a focus on responsible food purchasing and waste reduction.

Green lodging certifier Green Seal has extended its ecolabeling program to restaurants and foodservice establishments that reduce their environmental impacts, the nonprofit said Thursday.
The GS-46 Environmental Standard for Restaurants and Foodservices identified responsible food purchasing and waste reduction as the biggest opportunities for operators to reduce their toll on the environment. That's because food represents the largest source of a restaurant's impacts due to its production, which generates between 17 percent and 32 percent of human-based greenhouse gas emissions, according to the organization's research, which included lifecycle analyses.
The GS-46 also focuses on responsible water and energy management. Coincidentally, the U.S. Environmental Protection Agency today announced new Energy Star requirements for commercial griddles and ovens that are as much as 20 percent more efficient that standard models.
The GS-46 has three levels -- bronze, silver and gold -- and applies to all types of operations, such as full-service, limited-service, non-commercial and catering. The National Restaurant Association estimates there are 945,000 locations in the U.S., with expected sales this year of $566 billion and 13 million employees.
Green Seal charges operators fees for the on-site verification and continual monitoring, not including other expenses, such as for travel. The fees are based on revenue, and range from $2,380 in combined audit and monitoring fees for a small operator seeking bronze certification with annual sales of less than $500,000, to $7,650 in combined fees for a large establishment seeking gold certification with sales of more than $10 million.
Green Seal designed the standard with the input from more than 100 environmental and health organizations, trade groups, academia, suppliers and operators. The nonprofit also assigns its seal to hotels, retail stores and products used in airports, government facilities, schools, hospitals and offices buildings. Another recent standard released focuses on soaps, cleaners and shower products.

Submitted to _EMAIL_, May 17, 2017
The National Farmers Union (NFU) is pleased to provide input on the federal government's Budget 2017 consultation on the income tax deferral available in respect of deferred cash purchase tickets for deliveries of listed grains.
Cash ticket deferrals are currently available to any farmer who receives a cash purchase ticket when delivering wheat, oats, barley, rye, flaxseed, rapeseed and canola produced in Canada to a licensed primary elevator or process elevator. Primary elevators are country elevators that receive grain directly from farmers for storage and selling onward. Process elevators include flour mills, malting plants, crushers and ethanol plants that receive grain for processing into other products. Cash deferral tickets allow farmers to avoid excessive swings in taxable income from year to year due to the timing and availability of delivery opportunities.
The Income Tax Act currently allows a farmer to deliver grain and defer being paid for it until the next tax year. Farmers are able to calculate their income tax based on the tax year in which they receive payment. The present consultation is seeking input on the value of the current tax measures and the implications of eliminating the deferred cash purchase tickets measure, which would make all income from grain sales taxable in the year the grain is delivered.
Cash ticket deferral was not linked to the historical role of the Canadian Wheat Board (CWB) and its international grain shipment agreements as was erroneously stated in the budget document. This error is immediately apparent, as the CWB was never sole purchaser of western Canadian rye, flaxseed, rapeseed or canola, and the ability to market oats was taken away from the CWB in 1989.
The use of cash ticket deferrals is a long-standing practice that enables farmers to even out their taxable income from year to year. This option is particularly important to unincorporated farms that operate on a cash basis for tax purposes, as it is one of the only tools available to even out tax obligations from year to year. The measure recognizes that farmers make their annual income by selling the year's crop while facing a great deal of variability in the yield, price and value of rotational crops, and other factors from year to year. Unlike many other industries, agriculture experiences very wide and unavoidable fluctuations in production levels due to the unpredictability and variability of weather. In addition, commodity prices vary substantially from year to year. The combination of uneven annual volume of production and volatile commodity prices means farmers can face a high income one year and very low, or even negative, income the next while spending the same amount on expenses. Without the ability to use the cash ticket deferral option, farmers would find themselves in the top tax bracket one year and in very different situation the next, potentially hampering their ability to pay for upfront expenses.
If farmers were not able to defer payment, they would attempt to manage the timing of actual delivery instead, leading to potential bottlenecks and/or underutilization of the transportation system. The cash ticket deferral measure also recognizes that the timing of possible crop delivery is often outside of the farmer's control. For example, weather conditions can hamper grain movement by rail causing bottlenecks in the elevator system, the allotment of railcars to delivery points is determined by railways, and in the past few years the railways have been giving top priority to their lowest-cost westerly points as a way to meet mandatory monthly delivery requirements. Thus, due to unavoidable circumstances, some farmers might deliver two years' worth of crop in one year and none the following year. These conditions mean farmers receive their incomes on a much less predictable or regular schedule compared with tax-payers who receive a regular salary.
Cash ticket deferral is a valuable tool to help farmers manage their cash flow and allow them to take advantage of delivery opportunities. The grain transportation system will run more efficiently if farmers do not have to manage the timing of their grain deliveries in relation to income tax considerations. It would be unfair to require farmers to be taxable on more than one years' production in a given year due to conditions around grain delivery that are outside of the farmers' control.
Therefore, the NFU recommends:
- Keeping the option for income tax deferral in respect of deferred cash purchase tickets for deliveries of wheat, oats, barley, rye, flaxseed, rapeseed and canola
- Expanding the cash ticket deferral to include all other grains covered by the Canada Grains Act, namely beans, buckwheat, chick peas, corn, fababeans, lentils, mixed grain, mustard seed, peas, safflower seed, soybeans, sunflower seed, and triticale.

Tennessee BBS 4: Flycatchers to Corvids
35 year change: +1.43 (+22%) ± 0.65
Pewees showed a statistically significant modest upward trend in numbers on BBS routes in Tennessee, though this appears to have primarily occurred in the _PHONE_ period. Recent data suggest a possible slight decline.
35 year change: +1.32 (+50%) ± 0.50
Tennessee's only widespread Empidonax species has increased significantly, especially since 1990. Though this may in part be an "Appalachian bump," the upward trend appears to be sustained up to the present
35 year change: -0.01 (-18%) ± 0.02
Very limited data from a small number of routes showed no significant change in numbers of this uncommon and local nesting species.
35 year change: -0.03 (-81%) ± 0.02
Also uncommon, local, and with very limited data, the Least Flycatcher nonetheless showed a statistically significant downward trend. The skimpy data do not necessarily indicate an ecologically meaningful trend, however.
35 year change: +3.89 (+147%) ± 1.02
Phoebes have shown a dramatic increase on Tennessee BBS routes, especially since about 1985.
Great Crested Flycatcher
35 year change: +1.10 (+48%) ± 0.42
This species has also increased steadily, though less dramatically, throughout the BBS period.
35 year change: -0.24 (-5%) ± 0.70
Kingbird numbers have remained relatively stable on Tennessee BBS routes over the period.
35 year change: -2.31 (-90%) ± 0.54
As has been widely noted, shrikes have declined drastically and exponentially over the BBS period. There are hints that his decline may have stabilized in the last decade or so; even if it has, it still represents a huge decline from the 1966 levels.
35 year change: +3.57 (+72%) ± 1.54
All five species of Vireos recorded on Tennessee BBS routes have shown substantial and statistically significant increases over the period. In the case of the White-eyed this appears to have taken the form of a rapid rise beginning rather suddenly in the 1990s.
35 year change: +1.01 (+66%) ± 0.32
This species has shown a steady, modest increase over the BBS era.
35 year change: +0.16 (+195%) ± 0.07
Primarily restricted as a breeder to the eastern parts of Tennessee, the Blue-headed Vireo has increased dramatically since the early 1980s. This rise began well before the "Appalachian bump" period of the early 1990s and continues steadily to the present. This puts the apparent nesting pair I found in Lewis County in 2010 (well to the west of the typical breeding range) in context.
35 year change: +0.52 (+363%) ± 0.14
In contrast to the Blue-headed, the Warbling Vireo is primarily a bird of west Tennessee. It has shown an even more dramatic increase in numbers, rising steadily from near zero in the 1960s to being widespread, even abundant on some routes, in recent years.
35 year change: +6.05 (+77%) ± 1.07
This most ubiquitous vireo in Tennessee rose in number steadily from 1966 until about 1995, then apparently reached a plateau or even began a slight decline.
35 year change: -6.94 (-34%) ± 2.35
Blue Jays are not at their most conspicuous during the BBS season but nevertheless they are detected in large numbers on nearly all routes. The average counts have declined modestly but steadily over the decades. I found it interesting that there is no noticeable effect of the arrival of West Nile Virus in the early 2000s; the decline was ongoing before then and has continued at about the same rate since.
35 year change: +11.78 (+43%) ± 2.36
One of the most conspicuous and ubiquitous birds on the Tennessee BBS, American Crows have increased modestly over the period. Again, there is no noticeable West Nile Virus effect.
35 year change: +0.05 (+175%) ± 0.06
The "other" crow is only recorded in small numbers on a few Tennessee BBS routes. The apparent upward trend is not statistically significant overall, which is more a reflection of limited data than an indicator of real stable populations.
35 year change: +.03 ± 0.02
Ravens did not appear on the Tennessee BBS until the 1990s, and have been recorded in small numbers on a very few routes in east Tennessee in most years since then. There is a suggestion of a continuing upward trend but the data are too limited to evaluate this statistically.
Tennessee BBS index:
1: Waterfowl to Herons
2: Vultures to Doves
3: Cuckoos to Woodpeckers
4: Flycatchers to Corvids
Next: 5: Larks to Wrens

Do Genes Predict Friendship Networks? The Mitigating Role of School Context
Benjamin Domingue, University of Colorado at Boulder
Jason D. Boardman, University of Colorado at Boulder
Jason Fletcher, Yale University
Recent research suggests that the genotype of one friend in a friendship pair is predictive of the genotype of the second friend. These results provide tentative support for the genetic homophily perspective which has important implications for genetic and social epidemiology because it evidences a particular form of gene-environment correlation. This factor may have important implications for both environmental and genetic estimates on health and health-related behaviors that are of interests to social demographers. We extend this work by considering the ways in which school context shapes genetically similar friendships. Using the network, school, and genetic information from the National Longitudinal Study of Adolescent Health, we show that genetic homopily for the TaqI A polymorphism within the DRD2 gene is stronger in schools with greater levels of inequality. Our results highlight the fundamental role played by broad social structures in the extent to which genetic factors explain complex behaviors.

Raven is automatically gesturing too often Follow
If your Raven is mounted too close to your steering wheel, too close to the dash, slanted downward or is moving due to a loose mount this could cause frequent unintended gestures (short videos). If alignment is not an issue, the device may be gesturing due to an adhesive layer that needs to be peeled off. Follow the mounting directions below to rectify the issue.
Do not stack anything between the mount, adhesive, and dash:
Do not tilt Raven downward:
Incorrect: Tilted Correct: Level
If adjusting the location and view of Raven does not fix the gesturing issue, there may be a hidden plastic film on Raven's screen. Indications of an additional plastic film include:
- Under bright lighting Raven's screen does not look shiny and black
- Tiny bubble(s) on the bottom left corner of the screen. (See below)
- The screen easily scuffs
To remove the plastic film:
- Using a firm but non-abrasive tool, such as a business card, lift the corner of the film.
- Peel the remainder of the film off with your fingers.
*Proximity sensors on Raven are located in the center just above the displays on the front cover. If there is an object directly in front of the proximity sensor (within 10") then false gestures might be detected.

SPICE and the art of preamplifier design
Part 1: Background

Updated Sept. 18, 2001

Original PAS phono preamp | Line amplifier
Modification history | References
New phono preamp | Line amplifier choices

Purist II: no global feedback | Conclusions
This page is adapted from an article that originally appeared in Glass Audio, Vol. 9, No. 2, p. 1 and No. 4, p. 38, 1997. Internet links have been added. Circuits with current regulator diodes for linearizing the output have been eliminated because the small reduction in low order harmonic distortion was offset by a significant increase in noise-- overall sound quality was degraded. A design with rotary switch tone controls has been added.
Portions of the material here are repeated in Feedback and Fidelity, which was intended for a more popular and less technical publication than Glass Audio.
In this article we use SPICE to design preamplifiers of exceptional quality. The platform for experimentation was the venerable Dynaco PAS.5 So yes, we must confess that this article contains yet another PAS modification (several, really), but the emphasis will be on insight into the design rather than on construction details. All observable flaws of the original PAS have been eliminated, and we have even been able to replace the unobtainable tone controls (in the line amplifier versions that use them) with easy-to-find linear potentiometers. The most important construction details-- the chassis and power supply modifications-- have been presented previously5 and will only be summarized here.
The simulations in this article were run on the PSpice evaluation package, which consists of Schematics for entering circuits, PSpice for simulating them, Probe for viewing the simulation results. LTspice can apparently be used for these models. Appendix A contains some tips on running Pspice. Duncan Munro has a list of SPICE vendors that could contain some hidden treasures. Current versions of PSpice may enforce the maximum number of components more rigorously than the version I've been using, 6.3. All schematics in this article should run on current versions, but I've had circuits rejected by 7.1 that ran on 6.3.
The essential design goals are low distortion (sspecially high order), high headroom (the ability to produce a much larger output voltage than required to saturate power amplifiers), flat frequency response well beyond the audio range, non-inverting output polarity, and no frequency response irregularities at any stage of the circuit. I don't seek unlimited frequency response extension because I've found that RF interference picked up in the cables can cause serious sonic degradation. The preamplifier must be able to drive any reasonable load over any reasonable length of cable. This requires low output impedance and a feedback loop that remains stable under significant capacitive load.
I use negative feedback because it has great advantages and no drawbacks when properly implemented in a preamplifier. I design for high input impedance in each gain stage because it allows the use of small coupling capacitors, which have high self-resonant frequencies, well above the frequency range where they can affect the feedback loop. I've taken special pains to minimize the effects of RF interference introduced from the cables. I didn't use the highly linear mu-follower circuit, which operates with the full gain (mu) of the tube (too much gain in many cases and variable from tube to tube) because the compatible type of negative feedback reduces input impedance. I minimize the effect of electrolytic capacitors, which are highly nonlinear at best, in the signal path by configuring the tubes to draw for zero net ac current (or close to it) from each power supply tap.
The principal limitation imposed on the design was that it had to be constructed on a Dynaco PAS chassis using the original power transformer, whose high voltage winding is specified at a wimpy 10mA. I squeezed a little extra current out of it by using a separate filament transformer mounted on the back,5 but I was still limited to six tubes (two in new sockets mounted in chassis holes behind the line amplifier PC board). The tubes must be 12AX7s, which perform well at plate currents around 1mA, lower than other popular tubes used in preamplifiers (12AT7, 12AU7, 6DJ8). The 12AX7 is ideal for use with negative feedback (local or global) because of its high amplification factor (mu). A high-mu tube with NFB has much more precisely controlled gain than a low-mu tube without NFB.
I'm skeptical about the advantages of super-premium parts in well-designed circuits, although I use good quality partspolypropylene capacitors, metal film resistors, etc. I believe that when it comes to designing for optimum sound quality, the magic is in the circuit.
I'm pleased to report that with the help of SPICE modeling, all the design goals have been met with no compromises. The only limitation is that it doesn't have enough gain for low output moving coil cartridges, but its performance with high output cartridges is so outstanding that many listeners may not be tempted.
Much of the material in this and the next sections is covered in greater detail in Feedback and Fidelity.The advantages of negative feedback are well-known: It extends frequency response, reduces distortion, allows precise control of gain, reduces output impedance and decreases a circuit's sensitivity to component variations. Nevertheless, its audible side-effects can be so bothersome that it's fallen out of favor with many audiophiles. We have identified three side-effects.
The first is that NFB causes clipping to become much more abrupt as an amplifier is driven into saturation: the greater the feedback the harsher the clipping. This can result in the generation of really nasty sounding high order harmonics. For this reason feedback must be applied sparingly in power amplifiers. Saturation is not an issue in the modified PAS because of its enormous headroom. It can put out up to 50VRMS into high impedance loads (over 75k). The 1.27mA dc current drawn by the output cathode follower allows it to source roughly 0.0012RLOAD V(0-Peak) = 0.00085RLOAD VRMS into low impedance loads. Even with an extremely low load of 5k (driving two power amplifiers, each with a low 10k impedance: a worst case for biamplified speakers), the PAS can put out 4.25VRMS: well above the 1VRMS that can drive most power amplifiers into saturation.
The second side-effect of NFB is that it reduces an amplifier's stability. Poor stability is expressed as a low phase margin, the amount of additional phase shift (which could result from capacitance shunting the load) needed to drive the amplifier into oscillation. An amplifier with poor phase margin will have a high frequency peak in its frequency response and will ring in response to transient signals, especially when driving difficult, i.e., reactive loads. This ringing can cause sonic degradation. The capacitance of long output cables (20-40pF per foot) is sufficient to cause ringing in the unmodified PAS. There are several well-known circuit techniques for stabilizing feedback loops. The original PAS uses the most common of them: 33pF capacitor CLFB in shunt with 47kilohm feedback resistor RLFB (Fig. 1). As we shall see, this "solution" is something of a Trojan Horse! We shall describe a superior technique that has no discernible ill-effects.
RF interference is caused by a wide variety of sources: radio,
TV, cellular phones (with digital on the way), microwave ovens, lamp dimmers,
flourescent lights, and digital appliances such as computers and CD players.
(It is particularly difficult to eliminate inside CD players, where it
may be as responsible as jitter for "digititis.") It is virtually
omnipresent in urban, suburban, and all but the most remote rural areas.
It varies from time-to-time and place-to-place, and may be responsible
for many of the discrepancies in published amplifier reviews.
The exact mechanism by which RF interference degrades audio quality is not well-understood. The most likely cause is intermodulation distortion. Paul Miller6 described a series of experiments in which he inserted strong RF signals (swept to 200MHz) modulated with random audio noise (0-20kHz) into several amplifiers, and measured the resulting audio noise spectra. He claimed to find a strong correlation between the measured noise spectra and an amplifier's subjective sound quality. Although RF interference is occasionally mentioned in audiophile media7, it tends to get lost among dubious tweaks. There is a very simple test for determining if an amplifier is overly sensitive to RF interference: Turn the volume up and listen for a pop when you turn a nearby appliance on and off. A well-designed amplifier will remain silent.
There are five paths through which RF can enter an amplifier: (1) direct radiation, (2) power lines, (3) internally generated by digital circuitry or rectifiers8, (4) the input cable, and (5) the output cable (potentially the most serious in feedback circuits, and certainly the most neglected). Direct radiation (1) should have little effect on the well-enclosed PAS. RFI power line filters (for example,

Meeting of African Ambassadors of main countries of origin of African migrants in the Middle East and the Gulf Cooperation Council (GCC)
African Experts drawn from major countries of origin of migrant workers in the Middle East and the Gulf Cooperating Countries met to share experiences on international labour migration cooperation mechanisms aimed at improving labour migration governance and explore avenues for policy dialogue with Middle East Countries. This meeting responds to the recommendations by stakeholders in labour migration governance in Africa, for a multilateral process, for enhanced protection of teeming number of migrant workers of African descent in the Middle East.
The engagement of the African Union Commission with the diaspora in the Gulf started in 2016 with a desk study that maps the African diaspora living in the gulf and understands the modes and waves of migration. Since then, two field visits have been carried out to United Arab Emirates and Kuwait.
Available data show that the Middle East region is the second largest region of destination for African migrant workers due to cultural, religious and historic factors. An increasing number of African Member States have negotiated bilateral labour agreements with Middle East countries, including Jordan, Qatar and Saudi Arabia, mainly for the supply of domestic workers. Egypt, Ethiopia, Kenya, Sudan, South Africa and Uganda account for top African migrant workers in the Middle East.
Remittances from the Middle East continue to increase, with United Arab Emirates accounting for the second highest remittance sending country in 2017, followed by Saudi Arabia (World bank, 2017). In 2018, Egypt and Nigeria were the top receiving remittance countries in Africa, with a total of USD 28.9 million and USD 24.3 million respectively.
In spite of this, labour migration governance in the Middle East and GCC region is in dire need of policy and structural reforms in various areas including training and ethical recruitment, decent jobs, skills recognition, legal and consular services as well as protection of human rights in line with international standards. Qatar for instance, has announced its landmark labour reforms in the Kafala system , as labour migrants will be free to change jobs, do not require exit permits and are no longer subject to discriminatory minimum wage by 2020.
Unlike Asian countries, Africa does not have any labour migration multilateral cooperation agreement with the Middle East, hence there are gaps in the protection of African migrant workers and their families. To address this, Sri Lanka as the previous Chair of the Colombo process was invited to the meeting to share its experiences in managing Asian labour migrant workers. In his words, H.E. Ambassador Mr. Sumith Dassanayake stated that "As the previous chair of the Colombo process, Sri Lanka is delighted to share its experiences on managing labour migration from Sri Lanka to the Middle East and GCC region noting that migration is a global phenomenon with opportunities for both countries of origin and destination as well as migrants themselves".
The multilateral framework on labour migration management will be a State-led dialogue process to address issues of common interest between Africa and Middle East, mainly bothering protection of labour migrants, provision of decent jobs, fair and non-discriminatory wages as well as ensuring ethical practices in recruitment and employment.
On behalf of the ILO, Ms. Silvia Cormaci, the Manager for the Priority Actions of the AU-ILO-IOM-ECA Joint Programme on Labour Migration Governance for Development and Integration in Africa said that, "Current estimates, place the number of African migrants to the Middle East & GCC at three million. There is a need to identify solutions to the identified common challenges and enhance cooperation mechanisms between the key countries of origin and destination for migrant workers. Joint voice by many countries have greater impact than the lone voice of a single country. The ILO remains committed to support the process of engagement and the overall implementation of the AU-ILO-IOM-ECA Joint Programme on Labour Migration Governance for Development and Integration in Africa (JLMP Priority).
Also speaking during the meeting, the International Organization for Migration shared its experiences in establishing Inter State Consultation Mechanisms on Migration (ISCMs). The Chief of Mission, Ms. Maureen Achieng noted that "Though it is not as widely publicized in the media as migration to Europe, the GCC is increasingly a major destination of African migrants leaving the continent. The trends and more recent data show that the Middle East is the second largest region of destination for African migrant workers. Beyond existing bilateral agreements, a more integrated approach, in particular an inter-regional mechanism, is needed for African governments to engage the Middle East Countries to explore regular migration mechanisms, protection of migrant workers and their families and dignified return and reintegration for migrants who decide to go back to their home countries.. "
Making her remarks, the Minister of Labour and Social Affairs for Ethiopia, Dr. Ergogie Tesfaye stated that "As primary duty bearers to ensure the protection of the rights of migrant workers, the onus is on us, governments, to take the leadership and ownership of the processes of engagement with key receiving countries for our labour migrants. We have a critical role to ensure that we are well informed of the pre-existing information-sharing and policy dialogue forums at the regional, inter-regional or global level."
On behalf of the Commissioner for Social Affairs, the Director, Ms. Mariama Cisse stated the need for African to learn from existing multilateral processes like the Colombo Process and the Abu Dhabi Dialogue which has helped in improving the situation of Asian migrant workers in the Gulf countries. In her words " Gulf States are willing to engage the African region for a common interest and the Commission is ready to provide all necessary cooperation to make this a success". She noted that the outcomes of the discussions will be presented during the Africa-Middle East Dialogue which will be held in February, 2020.
In his remarks, H.E. Mr. Fafre Camara, the Ambassador of Mali and Chair of the Permanent Representatives Committee (PRC) on Multilateral Cooperation said, "Migration is an opportunity and a development and cohesion. We need to see the different opportunities offered by migration and collectively address the multitude of issues that our migrant workers face within and beyond the continent"

Intracellular scaling mechanisms
Organelle function is often directly related to organelle size. However, it is not necessarily absolute size but the organelle-to-cell-size ratio that is critical. Larger cells generally have increased metabolic demands, must segregate DNA over larger distances, and require larger cytokinetic rings to divide. Thus, organelles often must scale to the size of the cell. The need for scaling is particularly acute during early development during which cell size can change rapidly. Here, we highlight scaling mechanisms for cellular structures as diverse as centrosomes, nuclei, and the mitotic spindle, and distinguish them from more general mechanisms of size control. In some cases, scaling is a consequence of the underlying mechanism of organelle size control. In others, size-control mechanisms are not obviously related to cell size, implying that scaling results indirectly from cell-size-dependent regulation of size-control mechanisms.

Abstract
Aromatic copolyanhydrides based on the common diacids isophthalic acid (IPA), terephthalic acid (TA), 1,3-bis(p-carboxyphenoxy)propane (CPP), and fumaric acid (FA) were synthesized and characterized. The copolymers were highly soluble in chloroform or dichloromethane (>20% w/w) and melted at temperatures between 80 and 130 °C. In comparison, the respective homopolymers are insoluble and melt at temperatures above 250 °C. The copolymers were amorphous and had a weight-average molecular weight between 17 000 and 35 000. The thermal and solubility properties of the aromatic copolymers were dependent upon the copolymer composition. Copolymers of isophthalic acid or fumaric acid containing between 15 and 60 mol % CPP were highly soluble in dichloromethane or chloroform and melted at temperatures below 120 °C. The copolymers containing more than 60% CPP were less soluble and melted at progressively higher temperatures as the fraction of CPP was increased. Copolymers of IPA containing 10-90 % fumaric acid were soluble and melted at temperatures below 100 °C. The copolymers of terephthalic acid, however, were soluble and melted at relatively low temperatures (<100 °C) only in the range of 10-35 % TA content. The hydrolytic degradation of IPA and CPP copolymers was homogeneous with initial release of the IPA monomers and slower erosion of the CPP residues. Increasing the CPP content in the copolymer further slows the degradation and drug release. These polymers were stable upon storage at 25 °C and exposure to 2.5 Mrad of γ-irradiation. Biocompatibility, as compared to implantable polymers currently in clinical use, was good.

TITLE:
Measuring chain for measuring the noise of road vehicles according to the SPB method
DESCRIPTION:
The SPB (Statistical Pass-By Method) measuring equipment is a measuring chain of several devices connected in a system. The measuring chain includes a microphone, a modular precision sound analyzer, 2 photocells for vehicle speed measurements, a laptop computer, a microcontroller, and a humidity and temperature meter. It is intended for measuring the maximum noise level of passing road vehicles and determining the SPB index, which defines driving surfaces according to the noise they cause.
The measurement method is carried out in accordance with the SIST EN ISO 11819-1 standard. It determines the influence of car tires rolling on road surfaces on the emission of road traffic noise into the environment. The modular precision sound analyzer detects the maximum noise levels of passing vehicles via a microphone standing 7.5 m from the center of the considered driving lane on the test field. Photocells record the passage of vehicles at the measurement point. The speed is determined from the difference in the registration times of each photocell and from the mutual distance between the positions of the photocells, and at the same time the category of the individual vehicle is entered into the computer. After computer processing of the data, a regression curve of the maximum noise levels depending on the speed of the vehicles is determined depending on the type of vehicle.

We are given a set of circles, stored by their center points in an array $A$. In particular, the center of the $i$th circle is at coordinates $(A[i].x, A[i].y)$. All the circles have radius of $k$.
I want to find a subset of circles such that no circles in this subset intersect with each other, such that this subset is as large as possible.
I'm asked to find a way to solve this using a backtracking algorithm. Rather than to do it with brute force, is there a effective way to prune some of the branches?

 - $\begingroup$ 1. What have you tried? Where did you get stuck? We expect you to make a significant effort on your own before asking, and to show us in the question what you tried and where you got stuck. This is not a site where you can copy-paste your exercise problem and have us solve it for you. 2. What is the motivation for solving this with backtracking, as opposed to some other method? If this is an exercise from a class to help you practice backtracking, then asking us to solve the exercise for you won't help you learn -- you learn by struggling with these problems on your own. $\endgroup$

The way I can figure out of is using 3 invariant, 1 stores selected cycles, 1 stores unselected cycles, 1 with unchecked cycles, once you add a disk $n$ from unchecked to selected, you also add the disks overlap with $n$ into the unselected and remove them from checked list, that is a way to do pruning.
$\endgroup$

 - $\begingroup$ that's genius, how do you determine whether if you want to discard the changes though? $\endgroup$ Jan 3, 2015 at 15:19

 $\begingroup$ I personally would prefer to check the list that stores the unchecked cycles, basically for each turn you wants the size of that list as small as possible, and return the one with smallest size. And I do agree with D.W. as he mentioned the linear programming is way better, his answer is pretty cool and he also edited the problem description in a better way, so if you wanna pick him, it is fine. Welcome to the computer science community. $\endgroup$

If it were me, I would encode this as an instance of ILP (integer linear programming) and let an off-the-shelf ILP solver deal with the backtracking and pruning.
Introduce $n$ variables $x_1,\dots,x_n$, where $x_i=1$ means that you include the $i$th circle in the subset and $x_i=0$ means you don't include it. Add the following constraints:
 - $0 \le x_i \le 1$, for each $i$: this forces each $x_i$ to be either 0 or 1.
 - $x_i + x_j \le 1$, for each pair $i,j$ of circles that intersect each other: this enforces that you cannot choose two overlapping circles.
Now maximize the value of $x_1+x_2+\dots+x_n$ (this is the objective function). Ask an ILP solver to find the optimal solution for you. Internally, the ILP solver will likely use backtracking, pruning, branch-and-bound, and other sophisticated methods.
This will be a very efficient use of your time: rather than trying to program up each of those methods and debug your implementation, you can rely upon an existing well-tested ILP solver. Also, given the amount of effort that has gone into optimizing ILP solvers, this approach might well perform better than any backtracking algorithm you're likely to come up with.

 - $\begingroup$ Wow, yes, I see, I just read about integer linear programming, thank you for your effort! This problem does look like a typical linear programming problem. now i am struggling, you helped me more than HenryHey did (sorry), but his answer also make sense. so i do not know which one should be the correct answer. XD $\endgroup$ Jan 6, 2015 at 10:47
 - $\begingroup$ thank you very much, you are truly a wonderful person. I picked HenryHey's answer because it works. But for anyone who is reading this post please follow @D.W. his answer should be the better way to solve this problem. $\endgroup$ Jan 11, 2015 at 22:19

Prolongation of network lifetime is one of the most important issues of sensor networks. EEHF (Environmental Energy Harvesting Framework) is a framework that includes a data gathering scheme and estimates the energy gained from the environment by using the periodicity of environmental power. Thus, sensor nodes can use environmental energy efficiently and the network lifetime is extended. However, since the accuracy of the estimation depends on the length of the period, and the data gathering scheme used in EEHF does not take environmental energy into consideration, this method has room for improvement. In this paper, we propose a more accurate and adaptive energy estimation method that does not depend on the length of the period, and a data gathering scheme that is optimized for the environmental energy-based sensor network, in order to prolong the lifetime of environmental energy-based sensor networks.

Abstract This report focuses on how to design media messages about nutrition that will persuade people to adopt healthful behaviors. The Elaboration Likelihood Model (ELM) is used as a theoretical framework to explore different information-processing modes that individuals employ in a variety of communication situations. Studies from the fields of communication and psychology are briefly reviewed, with a focus on the source and message strategies that are most likely to persuade different types of audiences to change their nutritional attitudes and behaviors.

AS/400 Library List
From Wikipedia, the free encyclopedia - View original article
Jump to: navigation, search
Most systems have a way to find objects when a specific path is not specified. The same is true of the AS/400 and it uses an object called the library list (*LIBL). This object doesn't exist on its own and is always associated with another object like a job or a job description (*JOBD). As of OS/400 V5R1 the user portion of the Library List can contain up to 250 library names. Prior to that it could only have 25 libraries. (This is something to keep in mind when selling software because on OS/400 V4R5 and below a job description with more than 25 libraries in its library list cannot be restored.)
A job's library list consists of four sections:
As was mentioned above the user portion of the library list for any job can be stored in a job description so that when a job starts up it will use the list specified there. Some job descriptions specify the special value *SYSVAL which means that the library list can be found in the system value QUSRLIBL. The AS/400 Operating System will allow the programmer to delete a library that is in a job description or either of the library list system values provided there are no jobs locking the library. However, all future jobs that use these now tainted lists will fail to start.

GAS HOB INSTALLATION IN Sea Point
The easy way to cook with passion
Benefits of using a gas hob
Gas hobs offer numerous advantages when compared to electric hobs, for example:
- More precise control over the heat: Gas flames can be easily adjusted, while electric coils can only be turned on or off. This gives you greater control over the cooking process, which can help you to make perfectly cooked meals every single time.
- More intense heat: Gas hobs create more intense heat than electric hobs, which can help to bring out the flavors of food. This can be perfect for searing, sautéing, and grilling.
- Quicker heat-up time: Gas hobs heat up quickly, which can save you time when cooking. This is especially beneficial if you are short on time or if you are cooking for a big group.
- Simpler to clean: Gas stoves are simpler to maintain than electric stoves. This is because there are no coils to clean and the grates can simply be wiped down with a damp rag.
Additional details about the benefits of using a gas hob
- Gas stoves provide greater heat control over the heat than electric cooktops. This is because the flame of gas hobs can be easily adjusted, while electric coils can only be turned off and on. This gives you more control during the cooking process, something that can help you make delightful dishes every time.
For instance, if you are searing a steak, you must could control the heat extremely accurately. If the heat is too high, the steak will overcook. Alternatively, if the heat is too low, the steak will not sear properly. With a gas hob, you can easily regulate the heat to get the perfect sear.
- Flavor: Gas hobs produce more intense heat than electric hobs, enabling to an improved flavor in food. This is because gas flames deliver even heat to food compared to electric coils. When food is heated evenly, the flavors are distributed evenly, leading to a richer tasty dish.
As an example, if you're making a soup, you want the flavors of the ingredients mix together evenly. Using a gas hob, it's easy to warm the soup uniformly, which results in a more delicious soup.
- Convenience: Gas hobs heat up quickly, which can save you precious minutes when cooking. This is particularly helpful if you are in a rush or if you are cooking for a crowd of people.
For example, if you are making breakfast for a large group of people, you can save time by using a gas hob. The gas hob will heat up quickly, so you can start cooking right away.
- When it comes to safety, gas hobs are safer option. This is because gas hobs emit any sparks that can start fires.
For instance, if you are cooking with an hob and inadvertently you drop a substance on it, the chances ignite because of the sparks generated. However, it isn't a risk with a gas hob.

Chalcedony is one of the cryptocrystalline varieties of the mineral quartz, having a waxy luster. It may be semitransparent or translucent and is usually white to gray, grayish-blue or some shade of brown, sometimes nearly black. Other shades have been given different names. A clear red chalcedony is known as carnelian or sard; a green variety colored by nickel oxide is called chrysoprase. Prase is a dull green. Plasma is a bright to emerald-green chalcedony that is sometimes found with small spots of jasper resembling blood drops; it has been referred to as blood stone or heliotrope. Chalcedony is one of the few minerals other than quartz that is found in geodes.

text: Communication has a central role in raising awareness as well as influencing people to respond to climate change issues. Media has emerged as an essential source of communicating climate research to policymakers and the public around the world. However, media in developing countries, like Pakistan, lack the capacity to translate the scientific information and linking it to everyday life due to which the issue faces negligence on a wider scale. The proposed project aims to build the capacity of journalists and media persons of Pakistan through training workshops to effectively communicate the scientific information on climate change to policymakers and other stakeholders. The training workshop will serve as a platform for the media to interact with climate scientists and empower journalists and reporters to understand the technicalities of climate science and related uncertainties. Also, the project aims to disseminate the outcomes of the APN project on extreme events to the general public and students through dedicated news articles, TV interviews and seminars with a particular focus on highlighting the role of APN in promoting regional research. These activities would eventually contribute to better communication of the country's vulnerability to climate extremes and would ultimately bring the issue to the forefront of policy priorities.

How can you make a specific action based on the url by base.html?
I have two if -clauses as context statements in base.html. If there is algebra in the GET, then the given context should be shown.
My url.conf
from django.conf.urls.defaults import *
urlpatterns = patterns('',
 (r'^algebra/$', 'algebra'),
 (r'^mathematics/$','mathematics'),
My base.html in pseudo-code
 {% if algebra %}
 ... -- do this --
 {% endif %}
 {% if math %}
 {% endif %}

An alternative to Ned's variable-value-based method is to use two different templates that extend a common base template. E.g.
In templates/base.html:
 {% block main_body %}
 {% endblock main_body %}
 etc., etc.
Then have your algebra view use templates/algebra.html:
{% extends "base.html" %}
{% block main_body %}
 do algebra stuff here
{% end block main_body %}
and do something similar for math or whatever. Each approach has advantages and disadvantages. Pick the one that feels like the best fit to your problem.
Update: You pass "algebra.html" as the first argument to render_to_response(). It extends "base.html" in that it uses all of it except for the block(s) it explicitly replaces. See Template Inheritance for an explanation of how this works. Template inheritance is a very powerful concept for achieving a consistent look and feel across a large number of pages which differ in their body, but share some or all of the menus, etc. And you can do multi-level template inheritance which is extremely nice for managing sites that have subsections which have significant differences with the "main look" and yet want to share as much HTML/CSS as possible.
This is a key principle in DRY (Don't Repeat Yourself) in the template world.

What is your view -method? Is it def common_view(request): ctx = Context(); return_to_response("base.html", ctx)? – Masi Jan 5 '10 at 4:04

You don't show your view functions, but here's a simple structure:
def algebra(request):
 return common_view(request, algebra=True)
def math(request):
 return common_view(request, math=True)
def common_view(request, math=False, algebra=False):
 ctx = Context()
 ctx['algebra'] = algebra
 ctx['math'] = math
 # blah blah, all the other stuff you need in the view...
 return render_to_response("base.html", ctx)
(I might have some typos, it's off the top of my head).

Geo-Points are points of interest marked by an easy-to-understand information panel to inform the visitors about a geographical, geological, cultural or historical feature in the communities of the Geo-Naturepark region.
The essence of a landscape here in Central Europe is always a result of the historical influences of human activities. The cultural landscape is formed by the interplay between geological processes and land use by humans. Therefore, each landscape bears witness to how man has treated it over the centuries. These features may vary considerably from place to place, also because of the geological diversity.
Many features may not be immediately apparent to the casual visitor. The Geo-Points are an invitation to delve deeper into the exciting correlations, which shed light on and explain the history of the surrounding landscape and the people living there.
Geo-Points according to topics: geology, history, cultural landscape, and nature
Geo-Points sorted A to Z according to the name of the community
Below you will find maps with the position of each Geo-Point and short descriptions in German language. On the information panels however you will find English texts as well.


What is a terminal block? | Significance and Types
How do we connect two wires? By stripping the insulation at the ends and twisting them together? Yes, it works. But, is it safe? We can apply insulation tape over the joint or use a wire connector. But what if there are a number wires that need to be joint/connected near each other? Or, what if multiple outgoing wires are to be connected to a single incoming wire? Then this method will neither be safe nor be convenient anymore. Here we use terminal blocks.
What is a terminal block?
A terminal block (also called as connection terminal or terminal connector) is a modular block with an insulated frame that secures two or more wires together. It consists of a clamping component and a conducting strip. A typical simplest terminal block is as shown in the image below.

The insulating body of a terminal block houses a current carrying element (a metal strip or terminal bar). It also provides a base for clamping element. The body has a mounting arrangement so that the block can be easily mounted on or unmounted from a PCB or a mounting rail. Most terminal blocks are usually modular and mounted on DIN rail. That allows us to increase the number of terminals according to the requirements. Terminal blocks keep connections much more secure and wires well organized.
Types of terminal blocks
Electrical terminal blocks can be classified on the basis of structure, device type, termination options etc.
single level pass through or feed through terminal block
Single level pass through terminal block
Structure type
 - Single level pass-through terminal blocks: These are simply used to connect two wires together, i.e. wire-to-wire connection. These are also called as single feed terminal blocks. Single level terminal blocks are of the most simple type having one input contact and one output contact.
 - Dual level terminal blocks: These blocks have another level of connection terminal stacked on the first one. This arrangement is generally used to save space.
 - Three level terminal blocks: Just like dual level blocks, these have an extra level at the top. An advantage of using multilevel blocks is that multiple connections can be made in the same block.

Device type
ground terminal block and fuse terminal block
Image credits:
- Ground terminal blocks
These blocks often look like a single level feed through terminals. The exception is that these blocks and the metal connection where the wire is terminated are grounded to the panel or DIN rail on which the block is mounted.
- Fused connection terminals
These are similar to the pass-through blocks with an exception of the metal connection strip is replaced with a fuse. Therefore, the wires will be connected through a fuse providing an added protection.
- Thermocouple terminal blocks
These are designed to accept thermocouple lead connections. Some thermocouple connectors essentially clamp the thermocouple leads together on both sides of the block, eliminating the metal connection strip inside the block. However, in some thermocouple blocks, the metal connection strip of the same metal as that of the wire may be present.
- I/O blocks and sensor blocks
I/O blocks are used to make a connection between a device and a controller. Whereas, sensor blocks handle three or four wire devices such as proximity sensors.
- Disconnect terminal blocks
These blocks allow wires to be easily disconnected just by lifting a lever or knife switch. They can be used for convenient disconnection and connection without removing the wires. They are also known as switch blocks.
- Power Distribution blocks
These blocks are used in electrical power distribution. An electric power distribution terminal block is a convenient, economical and safer way to distribute power from a single input source to multiple outputs. One large wire is connected to the input terminal of the block and multiple output terminals are provided at the output. This way, wires are well arranged in a control panel giving it a neat, clean and professional look.

Clamping options in terminal blocks
 - Screw terminal: Screw clamp terminals are the most common type of connection method. The wire or conductor is simply pressed against the conductor strip in the block by tightening the screw. Screw terminals accommodate a very wide range of wire or conductor sizes.
 - Spring clamp: These type of terminals use spring pressure to retain the wire clamped. Spring clamps are a newer alternative to screw clamps and are generally used for relatively small wires.

 - Push-in terminal blocks: Push-in terminals allow you to connect a wire simply by inserting it. Most push-in terminals require the use of a ferrule. A ferrule strengthens the end of the wire/conductor. However, some push-in terminal blocks allow to insert a solid conductor directly or a stranded conductor by inserting a screwdriver into the release hole.
 - Insulation Displacement Connector (IDC): These connectors do not require us to strip the insulation for contact. We simply need to insert the wire without stripping the insulation, and the two sharp metal blades inside the terminal will cut through it to the conductor making proper contact.
 - Barrier terminal block: These are used where vibration is an issue. A spade or ring terminal is attached to the wire and then inserted into a bolt and tightened with a nut on the terminal block. This prevents loosening of the wire due to vibrations.

Factors Affecting Electrochemical Cells
Research Question:
How do the changeable electrodes of different reactivity affect the energy in Volts measured by a Voltmeter while the Solution and the Salt Bridge stay constant for every single trial by the same amount in each beaker?
Background Theory:
The conductance of an electrolyte depends upon the number of ions present in the solution. Therefore, the greater the number of ions in the solution the greater is the conductance. The number of ions produced by an electrolyte depends upon its nature. The strong electrolytes dissociate almost completely into ions in solutions and, therefore, their solutions have high conductance. On the other hand, weak electrolytes dissociate to only small extents and give lesser number of ions. Therefore, the solutions of weak electrolytes have low conductance. Electrolyte is any substance containing free ions that makes the substance electrically conductive. Ionic Solutions are the most common, but molten electrolytes and solid electrolytes are also possible.
Hypothesis:
As the Electrodes in the constant Sodiumsulfate solution varies after each trial, the electrolyte with the highest difference of reactivity should result the highest Voltage. The understanding behind this theory is the following. The used electrodes are in a specific order of reactivity. Therefore the element on top of the list (potassium) should react most and the element on bottom (copper) least. If both are used together in an electrochemical cell, this should more reactive than other elements (electrodes, such as zinc, calcium, aluminium and…). With a higher reactivity rate, the voltage also increases because of the number of ions released which related to a greater conductance. Apparatus

BMW History: Karl Rapp was an aircraft engine manufacturer, which is why the BMW logo symbolizes a spinning white propeller. After World War I the Treaty of Versailles prohibited Germany from making aircraft so BMW made railcar brakes. The first BMW motorcycle was introduced in 1923 and by 1933 they were producing cars. During World War II BMW produced engines, jet engines and weapons for the German army and the factory suffered major damage from allied bombs.
The first post-war BMW was produced in 1952 but they were too expensive for the market and sales were low. In 1959 BMW considered selling out to rival Daimler-Benz but new money from investors saved the day. Between 1994 and 2000 BMW bought the Rover Group which built the Rover, Mini and Land Rover brands and had the rights to the Austin, Morris, Riley, Triumph and Wolseley marques. In 2000 BMW sold their interest in the Rover Group but kept the rights to Mini, Rover, Triumph and other marques.

Mohammad Al Faruque, the director of UCI's Advanced Integrated Cyber-Physical Systems Lab, led the team which showed that a simple device, such as a smartphone, can capture acoustic signals that carry information about the precise movements of the printer's nozzle. These recordings can then be used to reverse engineer whatever object is being printed and re-create it somewhere else. Basically, this poses a huge security risk due to how easily detailed and confidential processes can be deciphered using common, everyday gadgets.
Industrial spies could accurately'steal' 3D objects by recording the sound of them being produced on a 3D printer. Researchers at the University of California, Irvine, have demonstrated a method by which a 3D design could be reverse-engineered by analysing the vibrations picked up from a common 3D printer.
The team of researchers at UCI's Advanced Integrated Cyber-Physical Systems Lab, led by Mohammad Al Faruque, were able to recreate a 3D-printed key-shaped object with 90 percent accuracy using the sound copying and processing technique they developed.
The team, led by Mohammad Al Faruque, director of UCI's Advanced Integrated Cyber-Physical Systems Lab, showed that a device as ordinary and ubiquitous as a smartphone can be placed next to a machine and capture acoustic signals that carry information about the precise movements of the printer's nozzle. The recording can then be used to reverse engineer the object being printed and re-create it elsewhere. Detailed processes may be decoded through this new kind of cyberattack, presenting important security risks.

"According to the fundamental laws of physics, energy is not consumed; it's converted from one form to another -- electromagnetic to kinetic, for example. Some forms of energy are translated in meaningful and useful ways; others become emissions, which may unintentionally disclose secret information," he explained, in a complicated way of saying making stuff = sound clues.

A team of researchers, headed by Mohammad Al Faruque at the University of California in Irvine, displayed the possibility of rebuilding a 3D model on the basis of the audio of the printer, while in operation. The position and movements of a 3D printer's extruder can be determined through the sounds made by it during work.
Led by Mohammad Al Faruque, director of the Advanced Integrated Cyber-Physical Systems lab, the team found that placing a smartphone alongside the machine as it printed objects layer-by-layer enabled them to capture the acoustic signals. It says that these recordings contain information about the precise movement of the nozzle, and that information can later be used to reverse engineer the item being printed.

How to move ZCS to another server
 KB 23043 Last updated on 2016-09-28
(0 votes)
In this article, we will explain how to move/migrate a zimbra server to another machine.
Both the source and destination zimbra servers must be running the same version. E.g. if source is running 8.6, the installed zimbra on the destination must be also 8.6.
In a nutshell, the solution is: stop zimbra on the source server, make a backup of /opt/zimbra, install new server, stop the old server, set up the new server's networking and hosts config, install software zcs to the new machine, substitute the /opt/zimbra on the new machine with the already made backup from the old machine, fix permissions, run a normal zcs install.
Below are the exact steps that needs to be taken, to complete the migration:
On the old server:
1. # su - zimbra
2. $ zmcontrol stop
3. $ exit
4. Make sure all zimbra services are stopped:
ps aux | grep zimbra
5. Now, you can copy the /opt/zimbra directory to another backup location, and from there to copy it to the destination server later, or you could mount external disc and copy it there, or simply copy it to the destination server (if already installed with the correct OS).
As root user, copy it to the remote machine (rsync can take a while, so before you put any deadline on a project, make sure you first rsync all data beforehand):
rsync -e ssh -axvzKHS /opt/zimbra/
that command will copy /opt/zimbra directory to a remote machine with IP, in the /tmp directory (using ssh). Or, you can copy it to a local mounted disk:
rsync -axvzKHS /opt/zimbra /mnt/zimbra_backup
6. Install a new server, with supported Operating System for the zcs version. The bit level (32-bit vs. 64-bit) or the Operating System build (RHEL 5, RHEL 6, Ubuntu 12, etc.) may be different than the source server.
7. Turn off the old ZCS Server
shutdown -h now
On the new server
1. Set up the new ZCS Server:
 - change the hostname as the old server
 - change the network settings as the old server
 - double check all other network settings work too (e.g. DNS), firewall, SELinux is stopped.
2. Download a version of ZCS on the new server. (The zcs version must be the same as the one on the source server).
3. As root, run the installer with the -s option:
./install.sh -s
That will only install the software packages.
4. When the install.sh -s completes, you can delete the /opt/zimbra directory.
rm -rf /opt/zimbra
5. Now, copy the /opt/zimbra directory backup we made in step 5, to the new server in /opt directory, so that the structure is the same
If you have copied it to a different server, just rsync it to the new server. If you used external disk, mount it and as root rsync your backup to the new location:
6. After to copy has finished, as root run:
/opt/zimbra/libexec/zmfixperms -e -v
7. As root rerun the installer without the -s option:
The installer will detect ZCS already installed, and will ask if you want to upgrade. Select Yes.

B, C, K, W system
From Wikipedia, the free encyclopedia
Jump to navigation Jump to search
The B, C, K, W system is a variant of combinatory logic that takes as primitive the combinators B, C, K, and W. This system was discovered by Haskell Curry in his doctoral thesis Grundlagen der kombinatorischen Logik, whose results are set out in Curry (1930).
Definition[edit]
The combinators are defined as follows:
 - B x y z = x (y z)
 - C x y z = x z y
 - K x y = x
 - W x y = x y y
Intuitively,
 - B x y z is the composition of the arguments x and y applied to the argument z;
 - C x y z swaps the arguments y and z;
 - K x y discards the argument y;
 - W x y duplicates the argument y.
Connection to other combinators[edit]
In recent decades, the SKI combinator calculus, with only two primitive combinators, K and S, has become the canonical approach to combinatory logic. B, C, and W can be expressed in terms of S and K as follows:
 - B = S (K S) K
 - C = S (S (K (S (K S) K)) S) (K K)
 - K = K
 - W = S S (S K)
Going the other direction, SKI can be defined in terms of B,C,K,W as:
 - I = W K
 - K = K
 - S = B (B (B W) C) (B B) = B (B W) (B B C).[1]
Connection to intuitionistic logic[edit]
The combinators B, C, K and W correspond to four well-known axioms of sentential logic:
AB: (BC) → ((AB) → (AC)),
AC: (A → (BC)) → (B → (AC)),
AK: A → (BA),
AW: (A → (AB)) → (AB).
Function application corresponds to the rule modus ponens:
MP: from A and AB infer B.
The axioms AB, AC, AK and AW, and the rule MP are complete for the implicational fragment of intuitionistic logic. In order for combinatory logic to have as a model:

The United States Department of Defense ran a project to analyse the current and historical use of marksmanship training. The analysis compared costs of using traditional live-fire training alone versus using simulator training. Research on the effectiveness of using the simulator training, conducted previously is used as a basis for the effectiveness analysis. The questions researched are:
"Can using the simulator training reduce training costs compared to using live-fire ranges alone?"
"Will continued use of the simulator training be as effective as using live fire alone?"
The project identifies current virtual training systems and analyses potential opportunities for cost savings. The data supported the hypothesis that the simulator training system will reduce costs over the years that it is used to supplement live-fire ranges. A cost analysis was conducted, and a sensitivity report generated. Results provided an estimate of the per-person cost of training, logistics savings, and virtual system benefits. The analysis concludes that a well-sequenced mix of simulator training and live-fire training would maximise cost savings — and is as good for overall marksmanship quality as live-fire alone.

Affliction: Health, Disease, Poverty
Veena Das
This book inaugurates a novel way of understanding the trajectories of health and disease in the context of poverty. Focusing on low-income neighborhoods in Delhi, it stitches together three different sets of issues. First, it examines the different trajectories of illness: What are the circumstances under which illness is absorbed within the normal and when does it exceed the normal. A second set of issues involves how different healers understand their own practices. The book asks: What is expert knowledge? What is it that the health practitioner knows and what does the patient know? How are... More
