provide some indication as to the period of its origin. Based on this information most jewelry experts believe that the Golash pearl brooch appear to be of Victorian origin, belonging to the mid-Victorian or Grand period, extending from 1860 to 1885. Circle brooches were a common design during the mid-Victorian period. Materials used for these brooches included gold, enameling, cabochon-cut deep-red garnets, pearls, and rose-cut diamonds. Margaret Flowers' book "Victorian Jewelry" gives black and white photographs of several circle brooches of the Mid-Victorian period. One of the circle brooches designed in 1865 is mounted with a large cabochon-cut deep-red garnet in the center, surrounded by a layer of pearls and rose-cut diamonds. A pendant made of pearls hangs from the brooch, with two loops of pearls on either side. Another circle brooch designed by Giuliano between 1865 and 1870, is made of enameled gold, with a cabochon-cut deep-red garnet in the center, surrounded by rows of rose-cut diamonds, and eight pearls placed symmetrically along the vertical and horizontal diameter of the circle. A drop-shaped pendant hangs from below the brooch, whose centerpiece is a drop-shaped deep-red garnet.
More circle brooches designed by Howell and James and displayed at the 1862 exhibition, are given on page 180. A photograph on page 181 also shows several circle brooches designed by Richard Green, and displayed at the 1862 exhibition. One of these brooches show a double row of pearls, surrounding a cabochon-cut gemstone in the center.
Evidence to show that Golash Quahog Pearl Brooch originated in the mid-Victorian period from 1860 to 1885
The Gholash Quahog pearl brooch, is essentially based on the same design as the above brooches of the mid-Victorian period. The brooch is made of enameled gold, a common material used for brooches during this period. The gemstone used as the centerpiece of the brooch is the large purple colored quahog pearl, known as the "Pearl of Venus." The black enamel design on a white enamel background, also depicts a trend that was common during the mid-Victorian period, a period of mourning for the Queen after the death of her beloved husband Prince Albert in 1861. During the first year of full mourning, black clothing and black jewelry were worn by the mourners. Black enameling of jewelry became popular during this period. Dark stones such as onyx, jet and vulcanite, were used in mourning jewelry. After the first year of mourning, half-mourning colors such as gray, mauve and purple clothing were used. Then purple amethysts, deep-red garnets and white pearls were also used in the mourning jewelry. The deep-red garnets used in the brooches described above, were a part of the mourning jewelry of this period. In the Gholash pearl brooch instead of a purple amethyst, a purple quahog pearl is used, the purple color being another feature of the half-mourning period. Another feature in the Gholash pearl brooch, similar to the Victorian brooches is the incorporation of a pendant to the brooch, whose centerpiece is another drop-shaped quahog pearl.
The mid-Victorian features in the Golash pearl brooch may be summarized as follows :-
1) The shape of the brooch being a circle, a common shape of brooches during this period.
2) The use of enameled gold for the brooch.
3) The use of a black enamel design on a white enamel background.
4) The use of a purple quahog pearl as the centerpiece of the brooch, purple being an accepted color during the half-mourning period.
5) The incorporation of a short pendant to the brooch, whose centerpiece is another purple drop-shaped quahog pearl. The use of purple color for the pendant again conforms to the accepted use of colors in jewelry during this period.
Thus the Gholash pearl brooch most probably originated in the mid-Victorian period from 1860 to 1885, nearly 150 years ago.
Golash seeks Benjamin Zucker's advice to obtain a reasonable price for his rare pearl brooch
Benjamin Zucker, renowned New York based gem expert, merchant and author
Golash had been seeking the advice of Benjamin Zucker, the president of Precious Stones Co. in New York, a renowned gemexpert, merchant and author, to obtain a reasonable price for his rare pearl brooch, by putting it up for sale at a reputed auction house like Christie's or Sotheby's. Zucker who was impressed by the pearl brooch, and described the quahog pearls in it as exceedingly rare and difficult to be valued, as there was nothing to compare it with, advised Golash to promote the pearl brooch by exhibiting it in natural history museums and exhibitions conducted by these museums, as well as in international gem and jewelry shows. He also advised Golash to find out everything about the provenance of the brooch, including its possible period of origin by consulting jewelry experts and historians, as a major part of the value of famous and historical pieces of gems and jewelry, was their provenance.
Was the Golash Quahog Pearl Brooch designed and crafted in Rhode Island, the hub of the jewelry industry in the United States, in the mid 19th-century?
Accordingly, Golash first met the owners of the antique shop at Newport, Rhode Island, where the pearl brooch was purchased. That was in the year 2002, two years after he purchased the pearl brooch. The antique shop was no more, and the two elderly ladies had since retired to Florida. He showed a picture of the pearl brooch to the old women, and asked them if they could provide more information on the history of the brooch. But unfortunately, the women said they could not remember it, which obviously meant that they could not even remember selling the piece to him. Drawing a blank in his efforts to trace its history, Golash consulted jewelry historians, who placed the probable origin of the pearl brooch to the Victorian period, somewhere between 1850 and 1875.
But, historians were not able to explain how such an antique piece of jewelry containing two exceedingly rare purple quahog pearls, made its appearance in the "Quahog capital of the World," Rhode Island, famous for its purple quahog pearls. The fact that the pearl brooch appeared in Rhode Island undoubtedly shows that the purple quahog pearls incorporated in it also originated in Rhode Island. The question now arises as to who designed the brooch and where it was crafted. The answer to these questions can only be a matter of conjecture. However, since the origin of the pearls was in Rhode Island, one can safely assume that the brooch was most probably designed and crafted, in one of the jewelry crafting centers in the United States at that time. The most important jewelry crafting center at that time in the United States, was Providence in Rhode Island. Thus, it was quite possible that the Golash Pearl Brooch was designed and crafted in Rhode Island itself. Though Rhode Island was famous as the center of the costume jewelry industry, it was quite possible that among the hundreds of jewelry firms that operated in Rhode Island at that time, there were at least some jewelry firms that still specialized in the manufacture of fine jewelry, such as the Golash Pearl Brooch. The designs for the jewelry manufacture was of course borrowed from the jewelry designers of Paris and London. Thus, the design of the Golash Pearl Brooch would have been inspired by the design of brooches produced during the mid-Victorian period, from _PHONE_
The history of the jewelry industry in Providence, Rhode Island
The history of jewelry manufacturing in the United States dates back to the period immediately after the revolution of 1776. The first jewelry shop where jewelry manufactured in the United States was sold, was opened in Providence, Rhode Island in August 1784, by a jeweler named Seril Dodge, who manufactured watches, clocks, and gold and silver jewelry. Dodge's business prospered as Providence became the center of the maritime trade, and soon several other jewelry shops were also opened. In 1794, as Seril Dodge was about to retire from business, his nephew Nehemiah Dodge opened his own jewelry shop for the manufacture of 18k gold jewelry. However, Nehemiah Dodge soon developed a technique for plating base metal like copper with gold. He became the first manufacturer of roll plated gold, which was used for turning out cheaper jewelry for the less wealthy. This was the beginning of the costume jewelry industry in the United States.
Providence, Jewelry Manufacturing Historic District
On the foundation laid by the Dodge family, the jewelry industry of Providence grew rapidly in the mid 19th-century, and soon expanded to other regions of New England. From 27 jewelry firms in 1830, employing 280 workers, the jewelry industry of Providence, Rhode Island, expanded to 150 companies, employing 2,700 workers by 1875, and by 1880, Rhode Island was the leading state in the manufacture of jewelry in the United States, accounting for more than one-quarter of the entire national jewelry production. By the year 1890, the number of jewelry firms in Providence, had grown to 200, employing 7,000 workers. Thus Rhode Island became the hub of the jewelry industry in the United states, at the turn of the

Selfe, Mr J to ask the Minister of Justice and Correctional Services
(1)Whether any correctional centres in the Eastern Cape are confronted with water shortages as at the latest specified date for which information is available; if not, what is the position in this regard; if so, which specified correctional centres; (2) what (a) immediate and (b) longer-term steps are being taken to alleviate the water shortages; (3) whether he has found that such water shortages have had any effect on (a) discipline and (b) operations of the specified correctional centres; if not, what is the position in this regard; if so, what are the relevant details?
1. Yes, the DCS centres have been affected by water shortages.
1.1 The following are the centres under OR Tambo District Municipality
- Mqanduli; and
The major challenge is the capacity of water treatment plants that cannot cope with the demand. However, the Department has bought water tankers for those centres to augment when there is no municipal supply.
1.2 In addition, the following centres under Chris Hani District Municipality:
- Lady Frere;
- Engcobo; and
The biggest challenge in this District is the high demand versus the capacity of the plant and ageing municipal infrastructure.
1.3 Furthermore, the following are the centres under Amathole District Municipality
The biggest challenge is drought (drying up of dams which causes silting). DCS has also bought water tankers for those centres to augment when there is no municipal supply.
1.4 The following are centres under Nelson Mandela Metro:
- St Albans Medium A;
- St Albans Medium B; and
- St Albans Maximum;
The main challenges are lack of rainfall and this started beginning of this year. DCS is procuring Jojo tanks and 3 water tankers and is in talks with the municipality for alternative ways of supply.
(a) The immediate intervention undertaken by the Department is procurement of storage tanks and water tankers for various areas;
(b) Medium to long term plans are to survey ground water availability in order to drill boreholes. The process of surveying has started at St Albans.
Municipalities, as water services authorities, need to upgrade their water treatment plants to be in line with the population demand and maintenance of plants thereof.
Offenders were addressed regarding the problem of water in the Nelson Mandela Bay Metropolitan (NMBM), and how this problem will affect the normal running of the activities in the Correctional centre. They were also alerted of attempts that were being made to mitigate the risk of no water. The briefing made offenders not to revolt or be aggressive as they see that even though there is no running water is provided for drinking and bathing.
Water shortages in centres compromises security and the entire operations of a centre due to the following reasons:
- No steam to prepare food for offenders;
- No hot water generation for bathing;
- The hygiene of offenders is severely compromised. The security of the centres is also at risk.

A mix of two pesticides had greater toxic effects on exposed salmon than would be expected from one separately, adding to concerns that health risks from pesticides are underestimated.
Risk assessment tests determine how dangerous chemicals are and if they should be regulated. They are usually done one compound at a time. However, most pesticide exposures in the natural world involve multiple chemicals that interact with each other and with living things.
In this study, scientists in Washington state looked at the effects of organophosphate and carbamate pesticides on juvenile coho salmon.
The fish were treated with several different combinations of the two pesticides. The activity of a brain enzyme called acetylcholine esterase (AChE) was measured to assess the total toxic effect. Pesticides target this enzyme to cause neurological damage.
Many of the combinations caused greater toxicity than was predicted mathematically using data generated from individual chemical exposure tests. Results like these with phthalates have just led the National Resesarch Council to recommend to the EPA that it change its risk assessment methods to reflect cumulative exposure to chemicals.
Agencies that develop regulations for pesticide use generally rely on data from studies using single chemicals. The new data provide more evidence that standards that rely on results from single chemical tests may greatly underestimate the actual risk of exposure to multiple pesticide pollutants.

Generally, there are many reasons for overheating of bearings in automatic wire crimping machines. Among them, there are several common reasons. The wire crimping machine manufacturer introduce several reasons as below:
Because the axis of the axle and the axis of the mechanical equipment driven by the terminal machine are not on the same line, or because of the inaccurate processing, the inner circle of the bearing cap is eccentric, so that the bearing cap and the axle are friction with each other. Light bearings heat, serious smoke, large high-speed motors will soon rub red. At this time, the machine should be stopped immediately, otherwise the automatic terminal machine will be burnt down.
3. The unbalance of inner and outer rings of steel ball bearings is one of the causes of heating.
The unbalance of inner and outer rings of terminal machine may be caused by machining. Because the seat and cover of automatic terminal machine are processed separately, sometimes the bearing holes on the two end caps are not coaxial (that is, the center line is not on one line). In addition, poor assembly, uneven tightness of the screw on the end cover, dust and dirt on the stop, etc., may also make the inner and outer rings unbalanced. If the inner and outer rings of the bearing are unbalanced, the steel beads and the inner and outer rings will be scraped, and the friction will increase and heat up. If there is no other reason, wipe the nose clean and reinstall, screw tighten one by one in diagonal order. A small amount of errors in processing can be improved by gradual automatic adjustment.
4. Too much or too little lubricating oil is also the cause of heating.
Bearing is used for a long time, the internal lubricant gradually reduces, resulting in insufficient lubrication, increased friction loss, so that the bearing heating, long-term oil shortage operation will cause bearing damage. Too much oil or too thick oil can also cause bearing overheating. In addition, if the lubricating oil is mixed with hard impurities, the bearings are not cleaned, or the bearings are cleaned with dirty oil, so that there are sand particles and iron chips in the bearings, the mechanical friction of the bearings will be increased and the bearings will be heated, and the bearings will be easily damaged due to the role of impurities.

The Independent review of deaths and serious incidents in police custody by Dame Elish Angiolini has been published by the Home Office today. It is the first and only review of policing practises and related processes following police related deaths.
The report offers the government a blueprint for change to urgently implement in the face of numerous recent concerning deaths.
It makes over 100 evidence based recommendations, which are intended to be a pragmatic way forward. These include important recommendations on:
- Access to justice for families, including through non-means tested legal representation for bereaved families from the earliest point following the death.
- Strengthening systems and structures of accountability, holding the police to account at an individual and corporate level.
- National Oversight and learning from deaths, such as through an 'Office for Article 2 Compliance' which would monitor and report on recommendations arising from deaths.
- Improved investigation, including through the phasing out of Ex-police officers as lead investigators within the IPCC.
- Tackling discrimination, through recognition of the disproportionate number of deaths of BAME people following restraint and the role of institutional racism, both within IPCC investigations and police training.
- Better treatment of vulnerable people, including through proper resourcing of national healthcare facilities to accommodate and respond to vulnerable people in urgent physical or mental health need coming into contact with the police.
- An end to delay, in which Article 2 related cases should be dealt with in the same time scales as a civilian homicide case.

The National Institute of Advanced Studies recently evaluated its experience with a programme driven approach to its research and other activities. The Committee set up for the purpose felt that the programme approach had yielded positive results based on the topicality of the research, clear statement of objectives, time-bound nature of activities, and deliverables. It was however also felt that there was inadequate tapping of potential synergies between programmes. This was largely believed to be the result of a weak link between programmes and schools. It was therefore decided to reorganize the schools in a way that generated the required synergies and enabled the programmes to function more effectively.
In keeping with this approach the schools were reorganized. The four schools that now function in NIAS are: School of Social Sciences, School of Humanities, School of Life Sciences and Engineering, and the School of Conflict and Security Studies. The schools consist of a group of programmes in a domain. The Schools are expected to be 'Programme driven' and have a research agenda aiding the programmes in them, as well as promoting trans-disciplinary research within and outside the school. The new organization of schools is expected to build synergy within and across disciplines and promote such interaction more vigorously. The schools are also expected to carry out activities related to the NIAS Courses and outreach activities. PhD scholars are expected to be affiliated to a programme within a school.

I ran across Picard categories in a totally different area of mathematics, but maybe it helps.
In short, a Picard category is a group object in the category of groupoids.
Picard categories come up when you study Picard stacks. Roughly, a Picard stack is a sheaf of Picard categories. The classical example is taking a two-term (perfect??) complex of sheaves, and asssociating to such a complex the Groupoid quotient of the one term by the other. This is important when you want to produce a geomteric object from such a complex. This is an important tool in defining virtual fundamental classes as in _URL_
Before I tell you to many things that are not true, here are the references I know of:
Lecture notes of Martin Olsson at _URL_ Lecture 5. You can even watch that on video: _URL_
The definitive reference is Expos'e XVIII of SGA 4. You used to be able to get that at the Grothendieck circle. Now its still availabe on all the usual Russian sites.
And finally there are very friendly and down to earth lectures of Barbara Fanechi Fantechi at _URL_ I think lecture 3 or lecture 4 is about Picard categories.

Uganda boasts a number of wetlands that have been listed as Wetlands of International Importance under the Ramsar convention. All these sites are recognized by BirdLife International as Important Bird Areas as well as providing a vital habitat for other threatened plants and animals.
Two of these wetlands are found within Uganda's national parks:
Lake Mburo-Nakivali Wetland System, Lake Mburo National Park
This unique habitat lies at the convergence of two biological zones, giving it very high biodiversity. It supports globally threatened species of birds such as the Papyrus Yellow Warbler and Shoebill, and two of the endangered cichlid fish species which have become extinct in the main lakes. It is the only area in Uganda in which the impala is found.
Murchison Falls-Albert Delta Wetland System, Murchison Falls National Park
The site stretches from the top of Murchison Falls to the delta at its confluence with Lake Albert. The delta forms a shallow area that is important for water birds, especially the shoebill, pelicans, darters and various heron species. It is also an important spawning and breeding ground for Lake Albert fisheries, containing indigenous fish species, and it forms a feeding and watering refuge for wildlife during dry seasons.

Uncle Bob's Bowling Game Kata
August 11, 2009
Someone mentioned Uncle Bob's Bowling Game Kata to me a few days ago; it is apparently famous as a tutorial on object-oriented programming and test-driven development, though I had never heard of either Uncle Bob or his Bowling Game Kata.
A game of tenpins bowling lasts ten frames, in each of which the bowler makes one or two attempts to knock down ten pins arranged in a triangle. If the bowler knocks down all ten pins on the first attempt (that's called a "strike"), he scores ten pins plus the number of pins knocked down on his next two rolls. If the bowler knocks down all ten pins after two attempts (that's called a "spare"), he scores ten pins plus the number of pins knocked down on his next roll. If the bowler fails to knock down all ten pins (that's called an "open frame"), he scores the number of pins he knocked down. The scores accumulate through all ten frames. At the last frame, if necessary, the pins are reset for one or two additional rolls to count the final bonus. The sample scoresheet below shows how the calculations work:
For instance, the score in the second frame is 9, the sum of the two balls in the open frame. The score in the third frame is 15, which is 10 for the spare plus 5 on the next ball. The score in the ninth frame is 20, which is 10 for the strike plus 10 for the spare on the first two balls of the tenth frame. The score in the tenth frame is 16, which is 10 for the spare plus 6 for the extra ball, which is a bonus ball not really part of any frame (the two balls of the tenth frame have already been rolled).
Your task is to write a function that calculates the score of a tenpins bowling game. When you are finished, you are welcome to read or run a suggested solution, or to post your solution or discuss the exercise in the comments below.

Aerokinesis is defined as ones natural ability to manifest energy and control air using the Mind.
Aerokinesis tech 1 So go outside and meditate for an hour, this only takes a small amount of concentration. Now, think how that wind would feel hitting you from the direction of your choice.Then, once you feel the wind start to kick up, try to make it as strong as you can.
Aerokinesis tech 2 Imagine strings of psi stretching off of your finger toward the winds. Pull not jerk, you hand where you want the wind to blow.This takes a while to master and eventually you will be able to bring strong winds.
Practicing Aerokinesis (Indoors) Hold your hands about four inches away from your face. Keep them about three inches apart from each other. Blow air in between your two hands. Choose one hand to move the air with. Make sure the other hand cannot feel the wind being blown past it. With the hand you've chosen, try to push the wind towards the other hand until you can feel it against your skin.
Medium tornado: To start off you need to meditate for at least an hour and after that you have to feel the wind and connect with the wind feel it rage form that rage in circles going up in the air.
Hand tornadoes: First you need to meditate for an hour, imagine strings of energy connecting you to the wind now that you can feel the attachment to the wind, control the wind, and let it blow in the two directions to know what it feels like. Now imagine that tornadoes are forming around your hands and feel the wind getting stronger around your hand and blowing in your face with a lot of power, now let all your bad emotions go in the tornado around your hand and let it rage with power. When you have done it the wind is suppose to be blowing like a tornado is in front of you.
Air balls: First, call a wind summon. Next gather air energy in your hands. Form it into a ball-like shape. Gather until there is nowhere for the energy to go but out. Release all air energy in a form of a ball. Air Blade Basically use your ablility to sharpen the air. Condense the air into a blade; this may help you visualize a sword or a knife. After it's condensed, focus on sharpening the blade, just keep sharpening until you feel that it's razor sharp, then either swing it,, or launch it in a wave.
Air Jump: First, concentrate on controlling the air around you. Then jump into the air. Then, when you reach the peak of your jump, focus and condense the air underneath your foot to become as hard as stone. Vacuum Speed Control the air in front of your leg, and in the path of the leg and move it somewhere else to create a vacuum. The lesser air pressure means lesser air resistance, and you will kick faster.
Resistance shield: Visualize the molecules in the air being drawn to you, and compacting tightly as a shield around your body, visualize the shield being a sphere over your body bonded by the air molecules and time you breathe, more molecules compacting on the sphere, keep visualizing the sphere becoming denser.
Air Pressure Wave: Visualize air molecules being drawn to your palms, and visualize those atoms stacking up as a wall of tightly bonding air atoms in front of you. Visualize your hands being filled with the substance of air within it. Feel it flowing through your body. And visualize it building up in your palms. Now put your palms on the wall of pressured air and visualize your air ki blasting out at the wall and push it.
WHIRLWIND ATTACK: Highly dangerous First do a wind summon and after that spin around making the air go around spinning faster and make the air lift you above the ground and move the whirlwind around the area like a tornado and pick up stuff and make it hit something.
Flying: First you power-up using any method(s) that feel right for you. Now levitate now while levitating use your ki from your chakra point and have your ki come out of your body and push you into the direction in which you want to go.

BACKGROUND: Implicit negative attitudes towards other races are important in certain kinds of prejudicial social behaviour. Emotional mechanisms are thought to be involved in mediating implicit "outgroup" bias but there is little evidence concerning the underlying neurobiology. The aim of the present study was to examine the role of noradrenergic mechanisms in the generation of implicit racial attitudes. METHODS: Healthy volunteers (n = 36) of white ethnic origin, received a single oral dose of the β-adrenoceptor antagonist, propranolol (40 mg), in a randomised, double-blind, parallel group, placebo-controlled, design. Participants completed an explicit measure of prejudice and the racial implicit association test (IAT), 1-2 h after propranolol administration. RESULTS: Relative to placebo, propranolol significantly lowered heart rate and abolished implicit racial bias, without affecting the measure of explicit racial prejudice. Propranolol did not affect subjective mood. CONCLUSIONS: Our results indicate that β-adrenoceptors play a role in the expression of implicit racial attitudes suggesting that noradrenaline-related emotional mechanisms may mediate negative racial bias. Our findings may also have practical importance given that propranolol is a widely used drug. However, further studies will be needed to examine whether a similar effect can be demonstrated in the course of clinical treatment.

Controlled alternate partial root-zone irrigation (CAPRI), also called partial root-zone drying (PRD) in other literature, is a new irrigation technique and may improve the water use efficiency of crop production without significant yield reduction. It involves part of the root system being exposed to drying soil while the remaining part is irrigated normally. The wetted and dried sides of the root system are alternated with a frequency according to soil drying rate and crop water requirement. The irrigation system is developed on the basis of two theoretical backgrounds. (i) Fully irrigated plants usually have widely opened stomata. A small narrowing of the stomatal opening may reduce water loss substantially with little effect on photosynthesis. (ii) Part of the root system in drying soil can respond to the drying by sending a root-sourced signal to the shoots where stomata may be inhibited so that water loss is reduced. In the field, however, the prediction that reduced stomatal opening may reduce water consumption may not materialize because stomatal control only constitutes part of the total transpirational resistance. The boundary resistance from the leaf surface to the outside of the canopy may be so substantial that reduction in stomatal conductance is small and may be partially compensated by the increase in leaf temperature. It is likely that densely populated field crops, such as wheat and maize, may have a different stomatal control over transpiration from that of fruit trees which are more sparsely separated. It was discussed how long the stomata can keep 'partially' closed when a prolonged and repeated 'partial' soil drying is applied and what role the rewatering-stimulated new root growth may play in sensing the repeated soil drying. The physiological and morphological alternation of plants under partial root-zone irrigation may bring more benefits to crops than improved water use efficiency where carbon redistribution among organs is crucial to the determination of the quantity and quality of the products.

Why controlled alternate partial root-zone irrigation (CAPRI)?
The effective use of irrigation water has become a key component in the production of field crops and high-quality fruit crops in arid and semi-arid areas. Irrigation has been the major driving force for agricultural development in these areas for some time. Efficient water use has become an important issue in recent years because the lack of available water resources in some areas is increasingly becoming a serious problem. Much effort has been spent on developing techniques such as RDI (regulated deficit irrigation) and CAPRI [controlled alternate partial root-zone irrigation or partial root-zone drying (PRD in the literature)] to improve field and fruit crop water use efficiency (WUE) (Goodwin et al., 1992; Boland et al., 1993; Kang et al., 1997, 1998, 2000a, b, 2001a, b, 2002a, b, 2003; ZS Liang et al., 1997, 1998; Loveys et al., 1997, 1998; Dry and Loveys, 1998, 1999, 2000a, b; Gu et al., 2000; Shi and Kang, 2000; Stoll et al., 2000; Han and Kang, 2002; Kang and Cai, 2002).
CAPRI is a new irrigation technique which requires that approximately half of the root system is always exposed to drying soil while the remaining half is irrigated as in full irrigation. The wetted and dried sides of the root system are alternated in a frequency according to crops, growing stages and soil water balance. This technique has the potential to reduce field-crop and fruit-tree water use significantly, increase canopy vigour, and maintain yields when compared with normal irrigation methods. This technique has two theoretical assumptions. (i) Fully irrigated plants usually have widely opened stomata. A small narrowing of the stomatal opening may reduce water loss substantially with little effect on photosynthesis (Jones, 1992). (ii) Part of the root system in drying soil can respond to drying by sending a root-sourced signal to the shoots where stomata may be closed to reduce water loss (Davies and Zhang, 1991).
Plants open their stomata for CO2 uptake and at the same time lose their internal water. Mathematical modelling of these two opposite diffusion processes has predicted that plants generally should have the capability to optimize their water use in the short term and to maximize their chance of survival over a drought in the longer term. In the short term, for example, during a day, their carbon gained is maximized with only a limited amount of water lost (Cowan, 1977, 1982; Farquhar and Sharkey, 1982). In the longer term, for example, over a season, their water loss should be regulated according to the amount of water available in the soil (Jones, 1980; Cowan, 1982, 1986). In a world where rainfall is unpredictable, the long-term regulation means that plants must be able to 'detect' the soil drying and then 'respond' to it by regulating their water consumption. Such a mechanism may be termed as a feed-forward mechanism, since such regulation, for example, reduced stomatal opening, may take place well before all the water available in the soil is completely depleted.
Early work from this laboratory (Zhang et al., 1987; Zhang and Davies, 1989a, b, 1990a, b; Davies and Zhang, 1991; J Liang et al., 1996a, 1997) has revealed that such a feed-forward mechanism may work through abscisic acid (ABA), and could act as a plant growth substance, as a signal of soil drying. ABA can be produced in the roots in the drying soil and transported through the transpiration stream to the shoots where the shoot physiology (mainly leaf expansion rate and stomatal opening) is regulated. This root-sourced signal may substantially reduce the water loss through stomata at a time when no water deficit is detectable in the shoots, and may be described as the first line of defence against a possible drought. With prolonged soil drying, a second line of defence may operate through a progressive wilting starting from the lower and older leaves. Massive amounts of ABA will be produced in these wilted leaves and be sent to the upper younger leaves and buds where water loss will be cut down further (Zhang and Davies, 1989b). Understandably, it is essential for the plants to maintain some turgor in their growing points for survival, even under a prolonged drought. With the decreasing availability of water in the soil, signals from the first and second lines of defence will increase in strength and stomata will close further. Therefore, it may be concluded that stomata do work in a responsive pattern.
Can this kind of responding mechanism be used to increase plant WUE? Typically, plant photosynthetic rate shows a saturation response as stomata open, while transpiration rate shows a more linear response. It would be expected that narrowing fully opened stomatal apertures would substantially reduce water loss but would have little effect on the rate of photosynthesis. If this can be achieved, then WUE, if calculated as the carbon gained per unit of water lost, will be improved at little expense of CO2 uptake.
Are stomata opened at maximum most of the day? Even well supplied with water, stomatal opening is also a function of the atmospheric conditions, i.e. the evaporation demand. Cowan (1977) and Farquhar and Sharkey (1982) suggested that stomata might tend to function in such a way that the diurnal course of conductance allows maximal carbon gain for a given amount of water lost. Their models suggested that this would be achieved if stomatal movement is such that it would hold the gain ratio G (G = E/A, where E is the rate of transpiration and A is the rate of carbon assimilation) constant over the course of the day. Cowan (1982) attributed this stomatal movement as a short-term optimal stomatal regulation. From this modelling, it can be seen that a 'midday depression' becomes more substantial when evaporation demand gets higher at midday, i.e. the increase of temperature that leads to a higher vapour pressure gradient between the inside and the outside of the leaves.
It has long been known that plants growing in dry land with periodic soil drying have a higher WUE (Bacon, 2004). Apparently the increased WUE should be an integrated result of both short-term, as a function of atmosphere condition, and long-term, as a function of soil water availability, regulation of water loss. Improved WUE with a responsive stomatal behaviour is indeed predicted by Cowan (1982) from an analysis of the optimization

Renewable energy installations like wind turbines and solar farms are usually tasked with preventing changes to the environment, but According to a study published in the journal Science, building wind and solar farms in the Sahara desert can increase rainfall and make more plants grow.they may cause some environmental change of their own.
Governments and energy providers around the world are increasingly turning to wind and solar power to generate electricity and to replace climate change-causing fossil fuels. But one group of researchers wondered how these power sources would affect the environment as they become more common. After all, filling the sky with turbine blades and covering the ground with solar panels is likely to changing things—at least a little bit.
To test the idea, the team used the Sahara desert as a testbed as its been the site of large renewable plants in the past. For this study the authors looked at what the desert would look like if it was covered substantially with wind turbines and solar panels. The researchers simulated the effects of around 79 terawatts of solar panels and 3 terawatts of wind turbines.
To put that number in perspective, the total amount of solar power added by all the world's nations in 2017 was slightly less than a tenth of a terawatt, so this research isn't immediately relevant for today's renewable installations. But it's a number not completely unconceivable in the far future.
They found that with enough solar panels and wind turbines, the atmosphere around the installations will heat up, both from wind turbines churning the air and from solar panels absorbing more sunlight. That increased ground temperature, combined with slower wind speeds thanks to the turbines. These conditions would then promote more rainfall.
According to the simulations, the net effect is that the Sahara could see twice as much rainfall with those renewable installations as it does now. While on average is a small increase, researchers believe those rains would fall in concentrated places, creating up to 20 inches more rain per year—a huge change with vast ecological ramifications.
In effect, humanity could terraform one of the most extreme climates on Earth just by harnessing the energy of the sun's rays and the world's winds.

According to folklore, you can predict the weather with a persimmon seed. Here's how to do it:
Cut open a persimmon seed. (Find persimmon fruit in your supermarket. It should be locally-grown to reflect your weather.)
Look at the shape of the kernel inside.
- If the kernel is spoon-shaped, lots of heavy, wet snow will fall. Spoon = shovel!
- If it is fork-shaped, you can expect powdery, light snow and a mild winter.
- If the kernel is knife-shaped, expect to be "cut" by icy, cutting winds.
It's best to use ripe seeds.
That's it! Now, what did you see?

Consider a finite group G. For any integer $m \geq 1$ set $\gamma(m) = \gamma_G(m)$ to be the number of elements $g \in G$ such that ord($g$) = $m$. We say that $m$ is a "possible order" for G if $\gamma(m) \geq 1$, that is, if there is at least one element $g \in G$ such that ord(g) = m.
Consider the cyclic group $G = C_{6} \times C_6$. List all possible orders for G, and for each $m \geq 1$ of them calculate the value of $\gamma_G(m)$.
From my other question, I thought that I would do this:
lcm(6,6) = 6
Integers dividing 6 = 1, 2, 3, 6. I therefore use the Euler function on these numbers to get the number of elements in each order, but thats wrong. The correct answer is:
$$\begin{matrix} m: & 1 & 2 & 3 & 6 \\ \varphi(m): & 1 & 3 & 8 & 24 \end{matrix} $$
Why is this?
EDIT: I found a theorem: G and H are groups. For any $g \in G$, ord(g) = m. $h \in H$, ord(h) = k. Then
$$ ord(g, h) = lcm(m,k) = \frac{m \cdot k}{(m, k)} $$
What does the comma bit mean at the bottom of the fraction?
Is this theorem useful?

Well, what made you use Euler's totient function for this? It is true that there is a specific case where that gives the answer, but this is not such a case. – Tobias Kildetoft Dec 12 '12 at 18:39
I thought that was how you calculate the number of elements in the order. How else do you do it? – Kaish Dec 12 '12 at 18:46
Euler's totient function gives you the number of elements of the given order in a cyclic group. This is not quite a cyclic group, but we can still use something like this, since we can see what the order of an element $(a,b)$ will be given the orders of $a$ and $b$. – Tobias Kildetoft Dec 12 '12 at 18:48
So how would I calculate those orders then? – Kaish Dec 12 '12 at 19:05
Yes, the theorem you found is very useful for this. The comma bit at the denominator should have been $(m,k)$ which means $\rm{gcd}(m,k)$, ie their greatest common divisor. – Tobias Kildetoft Dec 12 '12 at 19:19

A blood culture is a test to detect germs such as bacteria or fungi in the blood. One may be ordered when a child has symptoms of an infection — such as a high fever or chills — and the doctor suspects germs have spread into the blood. The culture can show what type of germ is causing the infection, which will determine how it is treated.
To do the test, the doctor will take a blood sample and send it to a lab for testing. Results are ready in a few days.
If a child is severely ill, the doctor may start treatment before the results are complete, basing treatment on the most likely cause of the infection. This can be changed to be specific for the microbe found when the culture is completed and the antibiotic sensitivity of the bacteria or fungi has been determined.
Why Do a Blood Culture?
During some illnesses, certain infection-causing bacteria and fungi can invade the bloodstream and spread into other parts of the body, away from the original infection site. Their presence in the blood usually means that a child has a serious infection. Such infections usually cause a more rapid heart rate, high fever, and an increase in the white blood cell count.
A blood culture can reveal a number of infections or problems, such as endocarditis, a severe and potentially life-threatening problem that occurs when bacteria in the bloodstream stick to the heart valves.
A blood culture might also detect the organism causing other infections like osteomyelitis, a bone infection often caused by Staphylococcus aureus, and cellulitis, a skin infection that involves areas of tissue just below the skin's surface.
How Is a Blood Culture Done?
The blood culture is done with a simple blood draw performed after the skin is cleansed with an alcohol pad and a special antibacterial solution. This careful skin sterilization is important because it prevents contamination of the blood that's being drawn. It kills bacteria that may be on the surface of the skin so that they don't appear in the blood culture and interfere with identification of the germ causing the infection.
Sometimes it seems like a lot of blood is drawn for the test, but it's important that enough be drawn for the culture to be accurate. This may be less than a teaspoon (5 milliliters) in babies and 1-2 teaspoons (5-10 milliliters) in older children, depending on their size. The amount of blood drawn is tiny compared with the amount of blood in the body, and it's quickly replenished (within 24-48 hours).
After the blood is sent to the lab, results usually are available in 1-2 days. If you have any questions about the test, be sure to speak with your doctor.


Learning Credal Sum-Product Networks
Amelie LevrayVaishak Belle.
learning tractable models for imprecise probabilities
Probabilistic representations, such as Bayesian and Markov networks, are fundamental to much of statistical machine learning. Thus, learning probabilistic representations directly from data is a deep challenge, the main computational bottleneck being inference that is intractable. Tractable learning is a powerful new paradigm that attempts to learn distributions that support efficient probabilistic querying. By leveraging local structure, representations such as sum-product networks (SPNs) can capture high tree-width models with many hidden layers, essentially a deep architecture, while still admitting a range of probabilistic queries to be computable in time polynomial in the network size. While the progress is impressive, numerous data sources are incomplete, and in the presence of missing data, structure learning methods nonetheless revert to single distributions without characterizing the loss in confidence. In recent work, credal sum-product networks, an imprecise extension of sum-product networks, were proposed to capture this robustness angle. In this work, we are interested in how such representations can be learnt and thus study how the computational machinery underlying tractable learning and inference can be generalized for imprecise probabilities.

Targets not preserved in saved games
When the game is saved in any Doom engine game, monster and missile targets are not registered in the save game file, so any monsters which were active at the time of saving the game become dormant upon loading the game again. However, their location and angle when the game was saved is preserved.
Demonstrating the effect
Here is one way to see the anomalous behavior:
- Start a new game of Doom II (MAP01) on I'm too young to die.
- When the program loads, you will be looking at two troopers with their backs to you. Ignore them for now; instead, walk west along the short corridor until you reach the balcony.
- Fire a bullet. Two grunting sounds will now indicate that you have attracted the troopers' attention.
- Save the game.
- Load the game you just saved.
- (Optional) Stand still for a minute or two and listen. One would expect to hear the breathing noise made by zombies as they walk around, but all is quiet.
- Carefully move back along the corridor to the starting point, keeping your eye on the opening to the north. As you move into each trooper's line of sight, one of two things will happen:
- If he is facing you, he will become active and start moving again.
- If he is not facing you, you will see him standing still.
So, even though the troopers woke up in step 3, they "fell asleep" during step 5.
Some distinguishable effects become evident because of the bug. The target of an incomplete arch-vile attack, for example, is not preserved in a saved game because of the bug. This means loading a saved game that includes such a situation will render the arch-vile attack harmless apart from the flame animation on the arch-vile's ex-target, which is displayed all the way through (as the corresponding flame thing had been spawned there as an effect of the attack). Similarly, the target of a revenant's missile is not stored in the save game data. Therefore, the missiles will no longer follow anything after it is restored.
The cause of this effect can be found in the Doom source code in p_saveg.c, in the functions P_ArchiveThinkers and P_UnarchiveThinkers.
In the Doom source code, the mobj_t structure is used to represent game objects such as monsters. Monster targets are stored in these structures as a field named target, which is a pointer to another mobj_t that the monster is currently targeting.
The Doom engine saves games by directly writing the raw structures used in memory to disk. When reloading saved games, pointers such as the target field are no longer valid (as the layout of structures within memory is different). When loading a game, the P_UnarchiveThinkers function deliberately sets target on all map objects to NULL in order to avoid crashes due to accessing invalid areas of memory. A null target indicates that a monster has no current target, causing active monsters to return to sleep.
A number of source ports have fixed the save game exploit, producing save game files with monsters that will continue to hound their previous target upon reloading the saved game. It is also possible to reconstruct infighting targets from standard Doom savegames by treating the stored mobj_t pointers as unique identifiers and analyzing their mutual relationships to determine which monster used to be which thinker. Mocha Doom uses this approach to reconstruct full target relationships from standard Doom savegames.

Returns a string representation of the key attribute(s) that is suitable for use in an HTML DOM id. This can be overwritten to customize the default generated string representation if desired. If you need to read back a key from a dom_id in order to query for the underlying database record, you should write a helper like 'person_record_from_dom_id' that will extract the key either based on the default implementation (which just joins all key attributes with '-') or on your own overwritten version of the method. By default, this implementation passes the key string through a method that replaces all characters that are invalid inside DOM ids, with valid ones. You need to make sure yourself that your dom ids are valid, in case you overwrite this method.

How an Absent Mother Affects Children
Discover why a maternal figure is so important in children's mental and emotional development.
When it comes to child development, an absent mother is not a trivial matter. In this article, we'll take an in-depth look at what can happen in this situation.
From the very beginning of a child's life, the mother is the most important figure of attachment. When a mother is not present in the life of her children, this can bring major consequences for their development.
A child's overall development is shaped by different aspects, from their physical needs to their emotional life. The relationship between a child and their mother or father is a vital part of their mental and emotional development.
A parent may be absent due to many different circumstances, some of them tragic. Not all children are lucky enough to grow up with a mother.
In other cases, although the mother is present, she is not able to spend enough time with her children, whether due to work commitments, relationship breakdown or other factors.
The absence of a mother figure can have a significant impact on the development of the child. However, the extent of the harm will depend on their environment and how the situation is managed.
What a mother gives her child
When we think about motherhood, the first word that comes to mind is protection. And with good reason.
A mother is the person who brings us into this world, and who nourishes and cares for us from the very beginning. This bond is an indispensable part of human existence.
As we grow older, our mother is there to comfort us whenever we feel down. She is there to soothe, calm and encourage us and chase away our fears. When we are nervous, scared, angry or in pain, she is the person we look to for unconditional support.
Feeling loved and valued by their mother will help a child to develop healthy self-esteem and build self-confidence.
An absent mother, therefore, can lead to deep insecurity in children. This is especially true when other adults in the child's life do not take action to address the situation.
This is one case where the support of a professional counsellor is indispensable.
Consequences of an absent mother
From the very start of a child's life, their mother is their most important figure of attachment. The lack of a mother figure can have major consequences.
Here are some of the main ones:
- Negative feelings. The child may experience feelings of loneliness or worthlessness, given that they don't receive the care and affection they need. This, in turn, can lead to anger or frustration.
- Poor behavior. This includes not responding to instructions, making unreasonable demands or hurting themselves or others. In more general terms, the child may seem to be constantly in a bad mood. These are common responses to the absence or loss of a parent or similar figure. Patience and affection are vital when it comes to helping children go through this phase.
- Problems with social relationships. Along the same lines, the child's other social relationships may also suffer. Whether due to lack of trust or because they have not learnt the necessary social skills, children with an absent mother figure tend to have trouble connecting with others. They may also develop a dependency on the people who are there for them.
- Emotional imbalances. This means irritability, low self-esteem, depression, anxiety, lack of motivation and more.
- Health issues. Faced with the loss or absence of their mother, some children may lose their appetite. Coupled with the emotional issues described above, this can lead to problems with the child's physical health. This should be addressed immediately by a professional.
How to help a child cope with an absent mother
Despite all of the above, there are ways to help a little one cope with the loss or absence of their mother and its after-effects.
Here are some tips for parents or guardians:
- Be their mother figure. Although this is far from easy, a father or any other guardian can fulfill the role of mom and dad. Tact, understanding and affection are critical, but this can be a good solution for all those involved. This way, you will fill the gap in their lives, at least partly.
- Find a substitute. With the help of aunts, grandmothers or any other close family member, you may be able to find someone to take on the role of a maternal figure. As in the previous case, it is important not to force the relationship. The bond will need to form gradually, on a basis of trust and love.
- Explain the situation to them. The truth will always find its way out. Tell your little one why it is that their mother is not in their life. Sooner or later, they will need to know.
If the child's mother is not completely absent, but, for example, works long hours away from home, the situation may be much easier to resolve.
Many studies have shown that the quality of shared time is far more important than the amount of time spent together.
It is important to give your child your full attention when you can. Remember that these moments help considerably.
What you do together is less important: play, take a walk or help with their homework. Just spending time with your child will help them to feel valued and supported.
Children understand when their mother takes an interest in them, loves them and supports them. It is this day-to-day presence that is critical for their development.

Mechatronics is the scientific word for the reverse engineering and/or copying of biological functions of an organism used in various appliances that today dot the landscape of living human beings.
Artificial intelligence is one such example, where instead of following repeated iterations of a particular code, the system taps into another source, and then tries to perform a different iteration; this is based on fuzzy logic. Fuzzy logic is something that humans have. We perform differently at different times on the same topic we are working on.
We get input from our skin, our five senses, and also from the subconscious part of the brain, where our previous history of what we observed, learned and unlearned is stored in vast numbers, and it is triggered by a part of the brain which controls these memory banks. Similar experiments have been used in robots to see whether they can themselves use repositories of information stored, and whether the software for them can pick up random sequences of information, and work on them. It has succeeded to some extent, but a lot more needs to be done.
Within the field of Mechatronics, lies the field of Biomechatronics, which is more concerned with the reverse engineering of the molecules and biological structures to help those in distress such as those with severed limbs, pathological loss of hearing, sight, and so on.
For those with severed limbs, often surgical intervention has helped to restore the limb back to near normal use. Here's where the biological science, the medical science and the informatics disciplines merge. The incorporation of a microprocessor within the severed and reattached limb enables the person to get a near full use of that severed limb. All this has been possible due to the interaction between the three disciplines. More such research is leading to newer developments.
For instance, artificial hearts are now being considered and are being tried out in research in 'dry labs' where only simulation is being done, to see whether that artificial heart can really function or not.
A more successful example of biomechatronics is the use of the cochlear implant which enables a nearly deaf person or even a blind person to get signals which can be used to restore part of the hearing or give enough signals which enable them to hear sounds, and signals that help them avoid colliding with object in their way.

I will be writing my bachelor thesis this semester (WS2020/2021).
Based on previous results of the iOS app ARPen, the thesis aims to expand upon the modeling techniques for free-hand 3D modeling. My supervisor is Philipp Wacker!
ARPen "in the Wild" - Expansion and Evaluation of an In-Situ 3D Modeling Application
The use of Augmented Reality (AR) has recently seen an increase in various areas of research. Still, 'handheld AR with a mid-air pen' is very much a niche research field. The ARPen System belongs to this field. It allows users to perform free-hand three-dimensional (3D) modeling directly in the real world by using a mobile pen. This Bachelor's thesis investigates how usable, functional, and effective the ARPen system is for 3D modeling. For that purpose, we conducted a user study. After providing each study participant a week-long experimenting phase with the application, we conducted semi-structured interviews. We analyzed the content by adapting grounded theory to identify the major themes of the interviews.Results showcase the system's strengths, such as the freedom it offers to create objects by sketching lines, the creation of primitives, the undo/redo feature, and the concept of the system. Moreover, they describe the system's shortcomings, such as perception problems of the 3D scene through the smartphone, precision problems of pen input, and system ergonomics. As some of these obstacles tie to the broader category of 'handheld AR with a midair pen', we provide design considerations for developing such a system.

. They can require rigorous maintenance, patching, and monitoring at multiple layers of the application topology.
Web Application Firewall (WAF), a feature of Azure Application Gateway, helps make security management much simpler, and helps application administrators guard against threats or intrusions. You can react to security threats faster, by patching known vulnerabilities at a central location, instead of securing individual web applications. You can easily convert existing application gateways to Application Gateway that is enabled for Web Application Firewall.
Here are some more notes about WAF:
- WAF provides centralized protection of your web applications from common exploits and vulnerabilities.
- You don't need to modify your code to make use of WAF.
- It can protect multiple web apps at the same time, behind Application Gateway.
- WAF is integrated with Microsoft Defender for Cloud.
- You can customize WAF rules and rule groups to suit your application requirements.
- As a best practice, you should use a WAF in front of any web-facing application, including applications on Azure VMs or in Azure App Service.
Best practice: Implement Network Watcher
Network Watcher provides tools to monitor resources and communications in an Azure virtual network. For example, you can monitor communications between a VM and an endpoint, such as another VM or FQDN. You can also view resources and resource relationships in a virtual network, or diagnose network traffic issues.
Figure 12: Network Watcher.
Here are a few more details:
- With Network Watcher, you can monitor and diagnose networking issues without signing in to VMs.
- You can trigger packet capture by setting alerts, and gain access to real-time performance information at the packet level. When you see an issue, you can investigate it in detail.
- As a best practice, use Network Watcher to review NSG flow logs.
- NSG flow logs in Network Watcher allow you to view information about ingress and egress IP traffic through an NSG.
- Flow logs are written in JSON format.
- Flow logs show outbound and inbound flows on a per-rule basis, and the network interface (NIC) to which the flow applies. They also show five-tuple information about the flow, and whether the traffic was allowed or denied.
Use partner tools in Azure Marketplace
For more complex network topologies, you might use security products from Microsoft partners, in particular network virtual appliances (NVAs).
- An NVA is a VM that does a network function, such as a firewall, WAN optimization, or other network function.
- NVAs bolster virtual network security and network functions. They can be deployed for:
- Highly available firewalls
- Intrusion prevention
- Intrusion detection
- WAN optimization
- Load balancing
- Certificate management
- Active Directory
- Multifactor authentication
- NVAs are available from many vendors in Azure Marketplace.
Best practice: Implement firewalls and NVAs in hub networks
In the hub, you normally manage the perimeter network (with access to the internet) through Azure Firewall, a firewall farm, or a WAF. The following table provides comparisons of these firewall options.
|WAFs||Web applications are common, and tend to suffer from vulnerabilities and potential exploits. WAFs are designed to detect attacks against web applications (HTTP/HTTPS). Compared with traditional firewall technology, WAFs have a set of specific features that protect internal web servers from threats.|
|Azure Firewall||Like NVA firewall farms, Azure Firewall uses a common administration mechanism and a set of security rules to protect workloads hosted in spoke networks. Azure Firewall also helps control access to on-premises networks. Azure Firewall has built-in scalability.|
|NVA firewalls||Like Azure Firewall, NVA firewall farms have a common administration mechanism and a set of security rules to protect workloads hosted in spoke networks. NVA firewalls also help control access to on-premises networks. NVA firewalls can be manually scaled behind a load balancer.
Though an NVA firewall has less specialized software than a WAF, it has broader application scope to filter and inspect any type of traffic in egress and ingress.
We recommend using one set of Azure firewalls (or NVAs) for traffic originating on the internet, and another for traffic originating on-premises. Using only one set of firewalls for both is a security risk, as it provides no security perimeter between the two sets of network traffic. Using separate firewall layers reduces the complexity of checking security rules, and it's clear which rules correspond to which incoming network request.

Israeli medical researchers say they have developed a new technique for blasting cancer tumours from the inside out which reduces the risk of the disease returning after treatment.Something new to put on the list of items for BDSers to boycott.
Tel Aviv University professors Yona Keisari and Itzhak Kelson are about to start clinical trials of a pin-sized radioactive implant that beams short-range alpha radiation from within the tumour.
Unlike conventional radiation therapy, which bombards the body with gamma rays from outside, the alpha particles "diffuse inside the tumour, spreading further and further before disintegrating," a university statement quoted Keisari as saying.
"It's like a cluster bomb -- instead of detonating at one point, the atoms continuously disperse and emit alpha particles at increasing distances."
The university said that the process takes about 10 days and leaves behind only non-radioactive and non-toxic amounts of lead.
"Not only are cancerous cells more reliably destroyed, but in the majority of cases the body develops immunity against the return of the tumour," the statement said.
The wire implant, inserted into the tumour by hypodermic needle, "decays harmlessly in the body," it added.
It went on to say that in pre-clinical trials on mice, one group had tumours removed surgically while another was treated with the radioactive wire.
"When cells from the tumour were reinjected into the subject, 100 percent of those treated surgically redeveloped their tumour, compared to only 50 percent of those treated with the radioactive wire," it said.
"The researchers have had excellent results with many types of cancer models, including lung, pancreatic, colon, breast, and brain tumours."
It added that the procedure would begin clinical trials at Beilinson hospital, near Tel Aviv, "soon."

Curving Ergo Crosswalk
Can tweaking the design of a common pedestrian crossing result in fewer accidents?
One of the shortlisted entries in the Seoul International Design Competition 2010 that stood out was the 'Ergo Crosswalk' by Korean designer Jae Min Lim. In his project, Jae tweaks the traditional shapes of Zebra crossing into curves to reflect how people jaywalk on roads.
He believes that by carving out a wider road area, there will be fewer accidents involving pedestrians. Moreover, the Zebra stripes will have built-in LEDs that glow red or green to indicate when it is safe for people to cross. The designer says:
"When people cross roads, they tend to take the fastest shortcut. they sometimes do it intentionally, but mostly it is an unconscious act. this kind of action violates the traffic regulations and sometimes threatens the safety of the pedestrians. The 'ergo crosswalk' is a design that makes people follow the law, as well as consider their habits or
unconscious actions. it will encourage pedestrians to follow the lines of the cross walk and protect them
from any potential danger. If regulations cannot force people to follow the law, wouldn't it be more reasonable to
change the law and fulfill the main purpose of keeping the safety and convenience of the pedestrian…"

Why Teachers In India Can't Be A Goal For Your SON, But More Profs & Educationists Are Men
More school teachers in India are women, but there are more men in higher education ranks - professors and educationists. Why this gender gap?
More school teachers in India are women, but there are more men in higher education ranks – professors and educationists. Why this gender gap?
The position of teachers in India is held sacred in the hearts of the people in our country. Today, September 5th, is celebrated as Teacher's Day or shikshak divas across the country to commemorate the birthday of Dr. Sarvepalli Radhakrishnan, the country's former president, scholar, and philosopher.
But that is not the topic of this article. I'd like to talk about something else. In this article, I'd like to talk about how society views this profession for both men and women.
For a dynamic and critical profession like teaching, it is always observed that there is a significant gender gap among teachers in the Indian education system.
We all understand the critical role that teachers play in the development of children and students, as well as the development of the country, but no one wants their child to become a teacher. And the parents who want their child to pursue this profession only see it as a career for their daughters because it is considered a career for ambitious women who can manage home and work at the same time. And for males, this job is always a no-no since it involves 'nurturing', and how can a guy nurture a child on this planet? Right?
This is why female teachers in India outnumber their male counterparts, although this tendency is only evident in pre-primary, primary, secondary schools, and the gap is nearly twice in contractual or tutoring positions. As we move up the ladder, though, we find the reverse pattern: males tend to occupy more jobs as professors, associate professors, and directors of educational institutions.
Here are some of the reasons why there is a dearth of female representation in higher-level positions in educational institutions.
Fewer women enrol for higher education after college or PG
Better education is required for higher positions, but many women do not pursue it owing to a lack of parental interest in investing in girls' education and saving money for girls' dowry, rather than spending it on their education.
Never miss a story from India's real women.
Register Now
In more marginalised and poorer communities, girls often drop out much earlier, due to domestic responsibilities and other duties such as caring for younger siblings.
Even in certain metropolitan regions, parents do not allow their daughters to travel to faraway places for education. Families provide less encouragement to girls and women for spending time at home on learning activities or finishing home assignments. There is almost certainly inadequate assistance from a spouse or from the in-laws for pursuing further education or work after marriage.
As a result, women who want to teach do not pursue further education and instead work as school teachers.
Women's poor NET (National Eligibility Test) performance
The National Eligibility Test (NET) is administered on behalf of the University Grants Commission (UGC) to determine an applicant's eligibility for Assistant Professorships, Junior Research Fellowships, or both, in Indian Universities and Colleges.
Despite the fact that more women apply for the exam, the number of women who pass the NET exam is consistently lower than the number of men who pass. This is explained by the fact that the age range of candidates allowed to take this test is 25-32, which is considered marriageable age for women in India, and as a result, women usually face a lack of support and a lack of a study environment.
Fewer departmental promotions for women
The belief that 'leadership jobs are masculine' is one of the reasons why fewer women hold higher-level positions. Another reason is many private institutes run by families want their male successors to take control.
All these factors favor men's advancement in Indian higher education institutions.
Hidden biases in the hiring process
Sexist questions at job interviews are not uncommon for women all around the world. When it comes to higher-level posts or permanent professors, the recruiting managers often prefer men over women. This is due to the fact that they assume that women will commit less time and will not be available at odd hours. Furthermore, a regular faculty member, especially one higher up the ladder, would have greater perks, such as maternity leave, and hiring managers may find this unpalatable.
Women also miss out on promotions because of their spouse's transferable work, family and children's obligations, a lack of confidence, a lack of female role models, and so on.
These are some of the key issues that contribute to a lack of female professors and institute leaders. However, this is not the only difference; the gender gap is also bigger on the other side. Male representation is lacking in the pre-primary and elementary sections of schools.
Let us now try to figure out what is causing fewer men to become teachers in India, especially in the pre-primary or primary sections.
Pay, prestige, preconceived notions, and pressure from society
Teaching in the lower grades is seen as 'low prestige'. It is widely assumed that teaching from KG to class 5 requires minimal intellect and is more like babysitting. As a result of these preconceived notions, these responsibilities are left to women.
Furthermore, money plays a role; the chances of promotion and increases are thinner in the early childhood area, therefore male teachers choose to go where the opportunities are greater.
One cause for the underrepresentation of male teachers in early childhood /elementary education is considered to be societal views. Men are believed to be 'less capable' with young children than women, and as a result, they (male teachers) have grown to think this and act accordingly. Male teachers are also frequently perceived to be less warm and loving than female counterparts.
Men outnumber women in administration, which might be because, after a few years in the classroom, men teachers may feel obliged to transfer out of the classroom and into administrative roles owing to cultural pressures.
Male teachers in India and suspicions of pedophilia
For various people, the phrase "male teacher in early childhood education" raises very different concerns. Some may perceive men dealing with young children negatively and wonder, "What are his hidden motives? What's the matter with him? Was he unable to secure other job offers?"
This is the most upsetting and disheartening reason why men prefer not to teach at elementary school level. With so many molestation trials against male perpetrators, many parents are concerned that the motivations of men teaching in elementary school classrooms are perverted.
Many misconceptions surround males who can exhibit guardianship for children, which is directly related to how 'caring' is regarded a feminine personality attribute. Parents may feel that a male teacher 'being nice' must be some type of deception, hiding a repulsive deed. Physical touch to a child hence raises questions, because far too many men (read fathers) are never trained to share these caring, personal moments with their own children, and find them suspect. The fact that every now and then cases against male teachers come to light does not help matters.
A mindset change about teachers in India is necessary
Society's perception of teaching and teachers must be altered. Female teachers outnumber male teachers in pre primary, primary, secondary classes because this job is seen as more 'convenient' for women because they can balance work and family life, and women are sometimes forced to choose this profession.
Men, on the other hand, are underrepresented because they are perceived as uncaring, unloving, and un-nurturing, and teaching also does not have good pay scales in a vicious circle, being perceived as work of women.
Change will happen, even if slowly
There is a significant gender disparity among teachers at the higher levels of education, as mentioned earlier. According to official data, the percentage of female teachers in higher education has been increasing in recent years. This indicates a positive growing trend toward closing the gender gap in higher education as a result of women-friendly government schemes and women-empowerment initiatives to increase female enrollment in higher education and provide them with employment opportunities.
However, continuous efforts from society and the government are required to completely eliminate the gender gaps in enrollment and employment that exist at various levels of education.
We must recognize that such under and over representation of teachers of a particular gender (both in elementary and high educational institutions) creates a sexist environment in the classroom. It also strengthens cultural beliefs about gender roles. Let's think differently.
