Abstract
The ion-pair extraction equilibria of the iron(II) and iron(III) chelates of 4-(2-pyridylazo)resorcinol (PAR, H2L) are described. The anionic chelates were extracted into chloroform with benzyldimethyltetradecylammonium chloride (QC1) as counter-ion. The extraction constants were estimated to be Kex1Fe(II) = [Q≫{FeII(HL)L≫}]0/[Q+][≫{FeII(HL)L≫}-] = 108.59 ± 0.11, Kex2Fe(II) = [Q2≫{FeIIL2≫}]o/ [Q+]2[≫{FeIIL2≫}2-] = 1012.17 ± 0.10 and Kex1Fe(III) = [Q≫{Fe(III)L2≫}]o/(Q+][≫{FeIIIL2≫}-] = 106.78 ± 0.15 at I = 0.10 and 20°, where [ ]o is concentration in the chloroform phase. Aggregation of Q≫{FeIIIL2≫} in chloroform was observed and the dimerization constant (Kd = [Q2≫{FeIIIL2≫}2]o/[Q≫{FeIIIL2≫}]o2) was evaluated as log Kd = 4.3 ± 0.3 at 20°. The neutral chelates of ≫{FeII(HL)2≫} and ≫{FeIII(HL)L≫}, and the ion-pair of the cationic chelate, ≫{FeIII(HL)2≫}ClO4, were also extracted into chloroform or nitrobenzene. The relationship between the forms and extraction properties of the iron(II) and iron(III) PAR chelates are discussed in connection with those of the nickel(II) and cobalt(III) complexes. Correlation between the extraction equilibrium data and the elution behaviour of some PAR chelates in ion-pair reversed-phase partition chromatography is also discussed.

I'm wondering about the pros and cons of storing summed values in a field vs. performing a sum() operation on a separate table. An example would be retrieving a list of items along with the number of purchases for each item. In this case, one could have an Items table and Purchases table whose purchases would need to be summed.
The pros of a summed value:
 - Simpler, faster SQL statements (no JOINs necessary, e.g., Items.item_id=Purchases.item_id)
The pros of sum():
 - Don't have to maintain 2 ways to obtain the values which could get out of sync because they require both an UPDATE and INSERT statements to change them (e.g., an INSERT of the purchase in the Purchases table and an UPDATE of the purchase_count field of Items.

THere is no right answer to such a question. The answer depends entirely on how the data is being used.
Two extremes. If you are rarely querying the data and there are lots of changes to historical data, then your system could spend a lot of effort keeping the sums consistent, when they are not needed.
On the other hand, if the data is "insert-only", and every record is repeatedly retrieved with the sum, then having the sums saves effort.
In general, the tendency is to favor the more normalized approach -- that is, doing the sum() at query time rather than maintaining it as a business rule. One clear advantage is that the values are consistent over time.
A second advantage is that the analytics can vary. Maybe today you need count of items. Maybe next week, you need the count of units. And the count of dollars. Or the net price difference. These change over time. Trying to capture them all up-front is challenging. The solution here is the break the problem into two pieces. Store the normalized data (with no magical sums) in one "database". Store summaries in "data marts" that can be modified to meet end-user goals. The data marts would be updated periodically -- once per day or once per week.
Normalized base data with period summaries is a strong architecture that meets many needs. But, there may be some cases where it is really a better idea to do the calculations on insert/update/delete rather than on select. Because such a solution often involves much more complexity (multiple triggers for instane), it has to justify itself strongly over a more normalized solution.

It depends on the application nature and usage.
You should make a calculation or review the usage(for an existing application) about which of the queries are more often. DML types of queries:
 - Summed value approach: suitable for more SELECT queries for browsing items and displaying information regarding the items - for example regular e-shops.
 - Using sum() approach: suitable for more UPDATE/INSERT queries - for example heavy store application that mainly consist of managing the store inventory.

PC zealots force Oxford University to rip down plaque honouring 19th century imperialist Cecil Rhodes after students branded him 'racist'
- Oxford college to remove plaque dedicated to imperialist Cecil Rhodes
- Students says it's racist as the college benefactor believed in colonialism
- Oriel College will also consider demands to tear down a statue of Rhodes
- Meanwhile British Nobel Prize winner Sir Tim Hunt is to leave the UK
An Oxford college is to remove a plaque dedicated to the 19th century imperialist Cecil Rhodes after students said it was 'racist'.
The monument, on a building owned by Oriel College, was erected in 1906 in recognition of the vast sums of money the mining magnate left to the university.
But campaigners claim that forcing ethnic minority students to walk past it on their way to lectures amounts to 'violence' because the college benefactor believed in colonialism.
Campaigners say forcing ethnic minority students to walk past the statue of Rhodes amounts to 'violence' because the Oriel College, Oxford, benefactor believed in colonialism
The university has also said it will consider demands to tear down a statue of Rhodes that stands at the entrance to the college.
A statement from Oriel said: 'The College does not share Cecil Rhodes's values or condone his racist views or actions. We commit to ensuring that acknowledgement of the historical fact of Rhodes's bequest to the College does not suggest celebration of his unacceptable views and actions, and we commit to placing any recognition of his bequest in a clear historical context.
'We are starting the process of consultation with Oxford City Council this week in advance of submitting a formal application for consent to remove the Rhodes plaque.
Its wording is a political tribute, and the College believes its continuing display on Oriel property is inconsistent with our principles.'
Rhodes, an advocate of colonial power in Africa, has been accused of helping to pave the way for apartheid. A diamond miner, he was an ardent expansionist of British influence and was the founder of Rhodesia (now Zimbabwe and Zambia).
As an Oxford graduate, he left money to the university. Many overseas students – including former US president Bill Clinton, the Australian PM Malcolm Turnbull and the singer Kris Kristofferson – have studied there on Rhodes Scholarships.
The campaign to remove the Oxford statue follows a similar university protest in South Africa and has been led by a group called Rhodes Must Fall. At the University of Cape Town, a statue of Rhodes was attacked and eventually taken down.
The university has also said it will consider demands to tear down a statue of Rhodes that stands at the entrance to the college
The Oxford campaigners argue that the views of the politician are incompatible with an 'inclusive culture' at the university.
A spokesman said: 'We note with excitement that the pressure mounted on Oriel College this past term by Rhodes Must Fall Oxford has led the college to a decision that it will immediately remove a plaque of racist and murderous colonialist – Cecil Rhodes – from a college building.'
While the plaque is not listed, the college needs the council's permission to remove it because it sits in a conservation area. The college said it would now begin a six-month consultation about the statue. But as the building has listed status, it may be that nothing can be changed.
'In the short term, we have put up a temporary notice in the window of the High Street building, below the statue, clarifying its historical context and the college's position on Rhodes,' the college said.
Annie Teriba, a Rhodes Must Fall campaigner, said earlier this year: 'There's a violence to having to walk past the statue every day on the way to your lectures, there's a violence to having to sit with paintings of former slave holders whilst writing your exams.'
ECCENTRIC PIONEER WHO BUILT AN AFRICAN EMPIRE
With his eccentric habits and rambling speeches, Cecil Rhodes was an unlikely figure to deliver swathes of Africa to the Empire.
A vicar's son from Bishop's Stortford, Hertfordshire, he became a famed imperialist, with Rhodesia, now split into Zimbabwe and Zambia, named after him.
However he remains controversial as many believe his policies helped to pave the way for apartheid.
Born in 1853, Rhodes attended a local grammar school as weak lungs prevented him being sent away. After going to work on a cotton farm in South Africa at 17, he moved into the diamond industry before belatedly obtaining a degree at Oxford, where students were intrigued by his colourful manner and monologues on the Empire.
By the age of 30, he had formed the De Beers Mining Company, which came to own 90 per cent of the world's diamond production and remains a major player to this day.
Despite being an unimpressive speaker, he earned respect for his original views and befriended many Boer politicians.
In 1881, Rhodes was elected to the parliament of the Cape Colony, in present-day South Africa and Namibia. One of his major aims was to open up the northern territories of what is now Zimbabwe, for mineral wealth, communications, and, eventually, white settlement.
Queen Victoria found his imperialism attractive, and he flattered her by saying: 'How could I dislike a sex to which your Majesty belongs?'
In 1889, he obtained a royal charter to start mining in what is now Botswana. From there, his pioneers began their hazardous march north, where they named the new territories Rhodesia in his honour.
But it was after he became prime minister of the Cape Colony that he introduced policies credited with laying the foundations for apartheid.
In 1892 he restricted the African vote to those with wealth and qualifications, and in 1894 he assigned an area for exclusively African development – effectively a native reserve.
Rhodes described it as 'a Bill for Africa'. In reality, it served to enforce segregation of native Africans.
His last years were soured by an unfortunate relationship with a Polish aristocratic adventuress, Princess Caroline Radziwill, who sought to manipulate Rhodes to promote her ideas of the British Empire.
He never married – pleading 'I have too much work on my hands' – and died of heart disease in 1902.
NOBEL PRIZE WINNER IN SEXISM FURORE TO QUIT UK
By Colin Fernandez
The Nobel Prize-winning scientist forced to resign after making light-hearted remarks about women is now planning to leave the country.
Sir Tim Hunt faced a storm of criticism after he suggested the problem with female scientists was that men 'fall in love with them'.
He claimed women should have separate laboratories and that they cry when criticised – in comments meant as a joke.
But such was the vilification from feminist scientists and students, University College London contacted Sir Tim's wife insisting he resign from his honorary post there or face the sack.
The father of two obliged and emailed in his resignation during the debacle in June.
Sir Tim Hunt faced a storm of criticism after he suggested the problem with female scientists was that men 'fall in love with them' (He is pictured with his wife Mary Collins at their home in Hertfordshire)
Now Sir Tim, 72 – who won the Nobel Prize for breakthroughs in cancer research – is leaving Britain to live in Japan, according to friends.
He will accompany his wife, Mary Collins, who is to leave her own professorship at UCL to take up a job at a Japanese University with a five-year tenure.
The couple are said to be hoping to put the row behind them.
Confirming the move yesterday, Professor Collins told the Daily Mail: 'This is a job I applied for before the Tim Hunt incident and is a very positive career move for me.'
But a friend of the couple, who live near Potters Bar, Hertfordshire, said the move would not be happening were it not for the witch-hunt that was triggered by the scientist's comments. The friend, who did not wish to be named, said Sir Tim continued to be upset by the false accusations of sexism, adding: 'It's very sad, it's quite clear it's based on their exhaustion.

'I've kept in touch with Tim over the past six months. They have been up and down, even quite recently. They have been emotionally affected by it. They have had a lot of criticism, he's had invitations to talk at conferences withdrawn on the grounds he's not a suitable person, or if he appeared it might produce a reaction, backlash or protest.'
The friend said the 'paradox' of the sexism row was the impact it has had on one of Britain's most senior female scientists. 'It's resulted in a very eminent female senior scientist having to leave the country. It's just craziness. I hope it puts some pressure on UCL.'
Sir Tim was speaking at a meeting of the World Conference of Science Journalists in Seoul, South Korea, when he made the controversial comments. He said: 'Let me tell you about my trouble with girls. Three things happen when they are in the lab. You fall in love with them, they fall in love with you, and when you criticise them, they cry.'
A lecturer in science journalism at City University in London, Connie St Louis, who attended the meeting, then posted an article mentioning his remarks on Twitter entitled 'Why are the British so embarrassing abroad?' This sparked the massive witch-hunt.
Mrs St Louis, a former BBC radio producer, said the event was 'utterly ruined' and asked: 'Really, does this Nobel laureate think we are still in Victorian times?'
The Mail later revealed she had falsified

Electromagnet for the Niryo Ned 6-Axis Robot Arm
Transform Ned into a high-precision robot arm by installing this electromagnet in place of its standard gripper.
What is an electromagnet?
An electromagnet is a device that produces a magnetic field when powered by an electric current. It works just like a traditional magnet, by attracting metal objects.
But an electromagnet offers the advantage of ceasing to be magnetic when the current is switched off. So it can be turned on and off like an electrical appliance.
Why equip the Niryo Ned robot arm with an electromagnet?
Thanks to its EasyConnect system, the Niryo Ned 6-axis educational robot arm can swap tools to handle various kinds of objects and exert a different action on them. For example you can install different-sized grippers, or a vacuum pump to pick up certain objects with suction and move them around.
This Niryo electromagnet is ideal for picking up very small metal objects, which is something that other accessories cannot necessarily do, even a precision gripper.
Technical specifications of the electromagnet for Niryo Ned
- Maximum operating width: 20 mm
- Picking surface: 20 mm
- Picking distance from end effector base: 22.5 mm
- Control interface: digital output
- Weight: 42 g
- Power supply: 5V
- Operating temperature: 5–45 °C

Why does groundwater move from where it has higher energy to where it has lower energy? Why doesn't it flow to where it has higher energy from where it has lower energy? What causes this to happen?
-- Willette jenkins (_EMAIL_), November 07, 2002
I'm not quite sure of your question. But as far as I know, groundwater moves from where it has high energy to where it has low energy. This is because of Hydraulic head. It depends on the groundwater's elevation and pressure. Because the pressure and elevation are higher at a particular place it intends to move towards where it is low.

Air transfer in submerged wheel
Air transfer in submerged wheel. A, in the cut, is a tank containing water, as shown. The hollow arms, B, communicate with a hollow shaft, C, and the bellows, E, screw valves, D, being employed to increase or diminish the area of the passages in the hollow arms B.
Each of the bellows, E, carries a weight, which, during a portion of the revolution, compresses the bellows and forces the air out of it through the hollow arms, B, and shaft, C, into bellows upon the opposite side of the wheel, which, being inverted, are expanded by the action of the weights, and, their buoyancy being thus increased on one side of the wheel, the latter is expected to turn constantly by virtue of the effort of the expanded bellows to rise to the surface.

What Is Sensory Adaptation?
Sensory adaptation allows people to acclimate to stark lighting, odd odors, or jarring sounds, like those often encountered at work.
People who have difficulty adjusting to changes in light may experience headaches and eye strain.

Sensory adaptation is a phenomenon in which sensory neurons change their level of sensitivity to a constant stimulus over time. This adaptation allows people to adapt to their environments while balancing the need to receive new sensory input. Neurons involved with smell, hearing, taste, touch, and sight can all exhibit this phenomenon. The only neurons which do not are nociceptors, the neurons involved in the sensation of pain. This is why the smell of a severe burn appears to dissipate quickly, while the pain lingers.
One of the best ways to illustrate sensory adaptation is by example. Many people are familiar with the adaptation of the eye to its environment. When someone emerges from a dark movie theater on a matinee day, the sunlight outside seems painfully bright. Within minutes, the eyes have adapted, and the light level feels comfortable and normal. The level of light has not changed. The receptors inside the eye have adjusted their sensitivity, recognizing that they need to be less sensitive to light to avoid damaging the retina. Conversely, someone walking into a movie theater will undergo the opposite, with the eyes increasing sensitivity to light to pick up all available visual information.

Likewise, many people have noticed that when they visit a stinky house, the first few minutes inside are often very uncomfortable. Over time, however, the smell seems to diminish. This is also a result of sensory adaptation. People may also note that if they pull the clothes worn in a strongly scented environment out of the hamper, the smell will still be evident, even if the clothes did not seem very smelly when they were thrown in the hamper. This is the result of the fact that while the clothes were worn, the receptors in the nose adapted so that the smell was not overwhelming, but when the clothes were taken off, the stimulus was no longer constant and as a result the nose is more sensitive to it.
Sensory adaptation can also be experienced with touch, in which hot water seems temperate after a few minutes, for example. Background noises are an excellent example of sensory adaptation in the case of hearing; these noises literally fade to the background because the ear is used to the constant stimulus. The tastebuds can also develop reduced sensitivity to intense stimuli, as people notice when strong flavors recede as they eat a dish.
Some people experience variances in sensory processing and perception, and sometimes this can result in a lack of sensory adaptation. For these individuals, for instance, a constant loud noise will always seem loud and it can result in high levels of stress. Likewise, people may have difficulty adapting to changes in light level, and sometimes this causes symptoms like headaches and eye strain.

I guess that's why, when I'm soaking in a hot tub, I prefer to be able to jump out and take a dip in a cold water pool for a while before getting back in.
After a while, just sitting in the hot water seems kind of boring, but when you've been in the cold it feels wonderful to get back in again.
The contrast to the adaptation is what makes it fun for me, otherwise it quickly gets old.

Post 3
I wonder if it would be a good idea to try and make it so that pain receptors had sensory adaption the way that other receptors do. I mean, not for everyone, because that could be dangerous (you could end up with the frog in the slowly heating water metaphor being true). But, for people who suffer from chronic pain in a particular area and there's no way to really control it.
I really find that very sad, because I know how much pain can affect your quality of life and make you feel tired and defeated. If there was a way of making it so that people with chronic pain would feel it less and less all the time, that would be pretty cool.

Prenatal Implications in A Robertsonian Translocation Silent Carrier Female- Fertility Science and Research
FSR
An engaging case report which highlights the development in fertility care, where genetic counselling and targeted prenatal diagnostic testing can help Robertsonian translocation (RT) carriers give birth to a normal baby. The study is published in Fertility Science and Research journal by Scientific Scholar.
Robertsonian translocation (RT) involves the end-to-end fusion of two acrocentric chromosomes. RT between chromosome 21 and any other acrocentric chromosome can lead to infertility, early pregnancy miscarriages or the birth of a Down syndrome (DS) baby in silent carriers.
DS is a genetic disorder characterised by distinct physical features and some degree of cognitive disability. Mainly there are three cytogenetic forms of DS – full trisomy 21, mosaic trisomy 21 and RT trisomy 21.
However, genetic counselling and targeted prenatal diagnostic testing can help RT carriers give birth to a normal baby.
Medical Dialogues team interacted with the lead author of the study, Dr Inder Mohan Singh Sandhu from the Department of Genetics, Sri Guru Ram Das Institute of Medical Sciences & Research, SGRDUHS, Amritsar, India
Dr Sandhu provided insights on the following-
1. What is Robertsonian Translocation and what is its clinical significance?
2. What are the different types of chromosomal abnormalities, specially Down Syndrome?
3. What role does genetic counselling plays in clinically handling such congenital abnormalities and what advice is given for expecting parents?
4. How was the experience in publishing with Fertility Science and Research and how has this journal contributing to your field of expertise?

Indirect taxes are among the most complex and controversial tax, which require a deep knowledge not only in legislation but also at the established business practice of the specific application. These taxes have a significant impact on cash flows. The share of VAT in total taxed revenue in the budget of Russian companies is very significant. In this regard, the tax authorities pay particular attention with tax audits.
Customs duties are the main expense for companies engaged in foreign economic activities. Administrative regulations on export-import operations also have a great influence on the activities to the tax payer.
Despite the fact that indirect taxes are present in the tax systems of many countries, the differences in calculating these taxes are considerable.
Thorough knowledge of indirect taxation both Russia and foreign countries West Union's employees manage to provide quality services in this area, which include:

hyperring
Contents
Contents
Idea
A hyperring is like a ring not with an underlying abelian group but an underlying canonical hypergroup.
It is a hypermonoid with additional ring-like structure and properties.
This means that in a hyperring RR addition is a multi-valued operation.
Definition
A hyperring is a non-empty set RR equipped with a hyper-addition +:R×RP *(R)+ : R\times R \to P^*(R) (where P *(R)P^*(R) is the set of non-empty subsets) and a multiplication :R×RR\cdot : R \times R \to R and with elements 0,1R0,1 \in R such that
 1. (R,+)(R,+) is a canonical hypergroup;
 2. (R,)(R,\cdot) is a monoid with identity element 11;
 3. r,sR:r(s+t)=rs+rt\forall r,s \in R : r(s+t) = r s + r t and (s+t)r=sr+tr(s + t) r = s r + t r;
 4. rR:r0=0r=0\forall r \in R : r \cdot 0 = 0 \cdot r = 0;
 5. 010 \neq 1.
We can form many examples of hyperrings by quotienting a ring RR by a subgroup GR ×G \subset R^{\times} of its multiplicative group.
A morphism of hyperrings is a map f:R 1R 2f : R_1 \to R_2 such that
 1. a,bR 1:f(a+b)f(a)+f(b)\forall a,b \in R_1 : f(a + b) \subset f(a) + f(b);
 2. a,bR 1:f(ab)=f(a)f(b)\forall a,b\in R_1 : f(a \cdot b) = f(a) \cdot f(b).
A hyperfield is a hyperring for which (R{0},)(R - \{0\}, \cdot) is a group.
Examples
Hyperfield extension of field with one element
The hyperfield extension of the field with one element is
K:=({0,1},+,) \mathbf{K} := (\{0,1\}, +, \cdot)
with additive neutral element 00 and the hyper-addition rule
1+1={0,1}. 1 + 1 = \{0,1\} \,.
This is to be thought of as the hyperring of integers modulo the relation "is 0 or not 0": think of 0K0 \in \mathbf{K} as being the integer 0 and of 1K1 \in \mathbf{K} as being any non-zero integer, then the addition rule says that 0 plus any non-zero integer is non-zero, and that the sum of a non-zero integer with another non-zero integer is either zero or non-zero.
The signature hyperfield S\mathbf{S}
Let S={0,1,1}\mathbf{S} = \{0,1,-1\} be the hyperfield with multiplication induced from \mathbb{Z} and with addition given by 0 being the additive unit and the laws
 - 1+1={1}1+1 = \{1\};
 - 1+1={1}-1 + -1 = \{-1\}
 - 1+1={1,0,1}1 + -1 = \{-1, 0, 1\}.
This we may think of as being the hyperring of integers modulo the relation "is positive or negative or 0": think of 11 as being any positive integer, 00 as being the integer 00 and 1-1 as being any negative integer. Then the hyper-addition law above encodes how the signature of integers behaves under addition.
Proposition
To each element, ϕ\phi, of Hom([X],S)Hom(\mathbb{Z}[X], \mathbf{S}) there corresponds an extended real number, Re(ϕ)[,]Re(\phi) \in [-\infty, \infty] given as a Dedekind cut. This is a surjective mapping. The inverse image of each real algebraic number contains three elements, while that of a nonalgebraic number is a singleton. For real algebraic α\alpha, the three homomorphisms from [X]\mathbb{Z}[X] to S\mathbf{S} are
P(T)limϵ0+signP(α+tϵ),t{1,0,1}. P(T) \mapsto \underset{\epsilon \to 0+} {lim} sign P(\alpha + t \epsilon), t \in \{-1, 0, 1\}.

On Feb. 7, the Cal Poly Black Academic Excellence Center hosted its annual "State of Blackness" event to celebrate Black History Month and discuss the experiences of Black students on campus.
To initiate the ceremony's opening, communications junior Jasmine Phipps recited an original poem titled, "Through the eyes of a POC," which described the challenges she faced as she acclimated to a predominantly white institution.
A piece of advice that Phipps would like to share with incoming students is to, "Keep remembering that you are black excellence, even if you aren't made to feel that way."
Following Phipps' poem, BAEC coordinator Christina Ortiz introduced the four panelists: English sophomore Kylynn Mireles, English junior Kendall Taylor, aerospace engineering senior Einstein Mwase and nutrition sophomore Nadja Braziel.
The students answered a series of questions concerning Cal Poly's efforts to foster an inclusive community as well as their experiences in and out of the classroom.
"Being able to see a lot of different people that didn't look like me was definitely shocking and being the only black person, I felt like I had to carry it all," Braziel shared about her freshman classes.
Along with discussions, the event included a social hour where students could choose a breakout group to attend. Breakout leaders included Black Student Union president Nailah DuBose, the Office of University Diversity and Inclusion's Vice President Dr. Isom, music educator Tracy Morgan and several others.

BBSRC plant scientists who 'could change the world' highlighted
5 December 2008
Two researchers who have received support from BBSRC and the Agricultural and Food Research Council (AFRC) – BBSRC's forerunner – have been highlighted in a News Feature in the journal Nature profiling five scientists working to improve global agricultural productivity.
With rising worldwide food prices and a growing global population, the world requires another 'green revolution', such as the one seen in the decades after the Second World War, to improve agricultural productivity. Zhang Jianhua, a plant physiologist who was supported by AFRC in the 1980s, and Julian Hibberd, a BBSRC-funded molecular biologist at the University of Cambridge, have been highlighted by Nature for the part they are playing in this.
Professor Doug Kell, Chief Executive of BBSRC, said: "The security of the world's food supply is going to be one of the defining issues of the next couple of decades. Zhang Jianhua, Julian Hibberd and other leading plant scientists are at the forefront of efforts to harness bioscience to help agricultural productivity cope with a changing climate and to keep pace with population growth. Many factors affect global food production, but the most fundamental are reflected in the ability of crops to produce the yield the world needs, and with the minimum level of inputs of water, energy and nutrients."
Zhang Jianhua, now at Hong Kong Baptist University, is a leading researcher and proponent of deficit irrigation. This irrigation technique utilises the knowledge that a plant suffering from drought stress can, at times, concentrate its resources on reproduction, rushing resources to the grains, believing that death is imminent. Zhang's research group is now examining the gene functions that are induced by water stress and the development of 'partial root drying', a technique that both keeps a plant alive and triggers the signals that gets it to send resources to the grain.
Zhang did the definitive work showing plant roots use the signalling hormone abscisic acid to communicate drought stress to the shoots, funded by an AFRC grant in Bill Davies's lab at Lancaster University. The impact of this research, and the work that Zhang continued in Hong Kong, is now being felt in rural China where he travels widely to promote deficit irrigation to farmers.
Julian Hibberd is a leader in research that seeks to understand the basic processes of photosynthesis. His work in the Department of Plant Sciences at the University of Cambridge has been supported by BBSRC over a number of years, and he is a former BBSRC David Phillips Fellow. Hibberd's research has taken him close to understanding the basis of a 'turbocharged' version of photosynthesis. This approach, which has evolved independently at least 45 times, allows plants (especially those in hotter climates) to fix carbon dioxide into a 4-carbon compound instead of the normal 3-carbon version, before feeding it into cells for further photosynthetic metabolism. This increases the local concentration of carbon dioxide and the overall efficiency of the process. Hibberd's work has shown how in the 'turbo' plants photosynthesis is separated into two main areas, and this requires both cellular specialisation and leaves that differ structurally from those in the commoner "3-carbon" plants.
Other researchers believe that if this approach can be incorporated into rice then yields could be increased by around 50 per cent from current levels. It may take several decades to achieve this but the fact that this form of photosynthesis has evolved independently on a number of occasion gives researchers cause for optimism.
Zhang Jianhua and Julian Hibberd are both featured in Nature, Vol 456, 4 December 2008, p.563-568. doi:10.1038/456563a

Genetic diversity and phylogenetic relationships among the annual Cicer species as revealed by isozyme polymorphism
Impact factor: 1.614 (Year: 1996)

Timeless limited access
M. Labdi, Larry D. Robertson, K. B Singh, A. Charrier. (1/1/1996). Genetic diversity and phylogenetic relationships among the annual Cicer species as revealed by isozyme polymorphism. Euphytica, 88, pp. 181-188.
There are few estimates of genetic variability within and among populations of the nine annual Cicer species and for the wild species this information is based on few accessions. The present study was undertaken to examine genetic variation within and between annual Cicer species. One hundred and thirty-nine accessions of nine annual Cicer species were used for electrophoretic analysis at ICARDA. High levels of polymorphism in all eight wild annual Cicer species was found. This is in contrast to earlier research which had shown high polymorphism only in C. reticulatum. Cicer reticulatum had the highest proportion of polymorphic loci. However, for the cultigen, among 14 loci assayed, only two were polymorphic, ADH and PGD2. The nine species formed four phylogenetic groups based on the neighbor-joining method. The first group comprised C. arietinum, C. Reticulatum and C. echinospermum, the second C. bijugum, C. judaicum and C. pinnatifidum, the third C. chorassanicum and C. yamashitae; and the fourth group consisted of one species, C. cuneatum. The phylogenetic tree developed from the neighbor-joining technique illustrated that C. reticulatum is the probable progenitor of C. arietinum and that C. echinospermum split off from a common ancestor at an earlier stage in the evolutionary history of Cicer. Genetic diversity data showed that the greatest diversity was within C. reticulatum and the lowest with the cultigen, C. arientinum. With the exception of C. reticulatum, genetic diversity increased with genetic distance from the cultigen. Little geographic variation in genetic diversity was found.

CANHÃO DA NAZARÉ
Nazaré Canyon is the biggest underwater ravine in Europe with about 200 km long, developing in the direction E-W and going to 5000 meters deep in the abyssal plain where it ends. The canyon headboard is less than 1 km from the coast to SW. This contiguity of the headboard to the shoreline harnesses singular oceanographically conditions that originate hydrodynamic and sedimentary transport processes, directly related to the presence of the canyon and its morphology.
The proximity of the canyon headboard to the coast affects the undulation characteristics in the less deep contiguous areas, as it is certified for the significant blistering of the wave, in the Praia do Norte, before the breaking zone in situations of West incidence. This phenomenon is due to the interaction of the undulation with the north edge of the headboard that results in a focalization or convergence of the wave for refraction and consequent blistering.
The increase of the wave height verified north of the canyon headboard doesn't happen south because, although the south edge promotes the focalization, the adjacent bay inverts the effect of the canyon, spreading the wave.
The modulation of the maritime disturbance carried through by the Hydrographic Institute, in the scope of "The North Canyon Show by Garret McNamara", suggests that this effect depends essentially on the course of the undulation incident. Results prove that the blistering in Praia do Norte is only verified in an expressive way in regimes of undulation around the direction of West incidence.
In the image is presented a typical situation that characterizes the phenomenon of blistering in Praia do Norte in a storm situation. The significant height in Praia do Norte is next to the eight meters, while in the south bay the waves have only a significant height of about four meters.

The Army Parachute Log Record, DA Form 3912, and AFTO 391
are history-type maintenance documents that accompany the
parachute canopy and pack tray assemblies through the period of
service of the individual assembly. The log record provides a means
of recording maintenance actions performed on a parachute canopy
assembly. Normally, a log record is initiated and attached to a right
rear riser upon receipt by a using unit. However, if the item is
subjected to alteration or modification by a maintenance activity
during the interim period from date of manufacture to receipt by a
using unit, the log record will be prepared by the activity performing
the maintenance function. Once initiated, a log record will be
attached to, and contained in, an affixed parachute log record/
inspection data pocket, until such time as the parachute canopy
assembly is destroyed or rendered unfit for further use or repair.
Additionally, should an item that requires a log record, be transferred
from one unit to another, the log record for the parachute assembly
will accompany the item in the transfer action.

Watch Pelle the Conqueror
- 2 hr 37 min
Pelle the Conqueror is a 1987 Danish-Swedish film directed by Bille August, based on an internationally acclaimed novel by Martin Andersen NexÃ¸. Set on the island of Bornholm, Denmark, in the early 20th century, the movie tells the story of a poor Swedish widower, Lasse (Max von Sydow), and his young son, Pelle (Pelle Hvenegaard), who move to Denmark in search of a better life. The film follows their struggles as they face poverty, discrimination, and social injustice, while striving to make a living and find a sense of belonging in a new country.
At the beginning of the film, Lasse and Pelle are seen in Sweden, living in a cramped and dark basement where they work as laborers in a farm. Lasse is old and weak, while Pelle is a curious and imaginative child who dreams of exploring the world around him. After Lasse loses his job, he decides to take a chance and go to Denmark, where he believes life is better. They arrive in a small Danish fishing village, where they are greeted with suspicion and hostility by the locals, who see them as unwanted outsiders.
Despite the challenges they face, Lasse and Pelle manage to find work at a farm owned by the wealthy farmer Kongstrup (Erik Paaske). However, they soon realize that their new employer is a brutal and exploitative man who treats his workers like slaves. They are forced to work long hours without rest and endure verbal and physical abuse. Pelle, who is sent to attend a school for poor children, also faces discrimination and bullying from his classmates, who ridicule him for his Swedish accent and poor clothes.
As the story progresses, Lasse becomes increasingly resentful of Kongstrup's abuse and decides to rebel against him in order to protect his rights and dignity. Meanwhile, Pelle becomes friends with a kind and intelligent girl, Anna, who helps him cope with his struggles and encourages him to pursue his dreams. Together, they explore the natural beauty of the island and learn about the world through books and stories.
The film's climax is a powerful and emotionally charged scene, where Lasse and Pelle confront Kongstrup and his gang, and demand their rights and freedom. The scene is a symbol of the struggle for justice and equality, and the power of hope and solidarity in the face of oppression.
Overall, Pelle the Conqueror is a captivating and poignant film that portrays the harsh realities of poverty and social inequality, as well as the resilience and courage of the human spirit. The performances of Max von Sydow and Pelle Hvenegaard are outstanding, conveying the depth and complexity of their characters with subtlety and sensitivity. The cinematography and music also add to the film's emotional impact, creating a vivid and immersive atmosphere that transports the viewers into the world of the story. Pelle the Conqueror won several awards, including the Palme d'Or at the Cannes Film Festival, and remains a timeless classic of Danish and Swedish cinema.
Pelle the Conqueror is a 1988 drama with a runtime of 2 hours and 37 minutes. It has received mostly positive reviews from critics and viewers, who have given it an IMDb score of 7.8.

they decided to found their own university < is it correct pls explain
I'm confused with this >> decided to
decided to found >> if to is to+inf >> it has to change like this [to+find] not [to+found] right?
decided to found >> decided +to >> if to is an prep. so it has to change like this [decided to finding]
or if you say in this case found is not participle of find so it means that in this sentence has 2 real verb. In grammatical it cannot has 2 real verb in the sentence without connector right?
I can see why you are confused. Sanjay is right. The infinitive "to" is always followed by a present tense verb.
He finds the treasure. He found the treasure. He decided to find the treasure.
But "decided to found the University" is correct in that it too uses the present tense verb. Why?
Because there are two different verbs that share "found". The verb "found" -- meaning to set up or establish -- and the verb "find" -- meaning to locate or discover.
I hope this helps.

World Association of Lesson Studies (WALS) International Conference 2018
23-26November 2018, Beijing Normal University, Beijing,People's Republic of China
LESSON STUDY AND TEACHER EDUCATION:
I. Invitation to Conference
The theme of the WALS 2018 is Lesson Study and Teacher Education: International Dialogue. It aims to provide a platform for an international and cross-cultural dialogue through which educators and researchers from different parts of the world can contribute to a broad vision for sharing their knowledge, understanding and experience of lesson study as a form of practice-based research.
Over the past decades, Lesson Study has contributed significantly to the quality enhancement of teaching and learning, teacher education, and development of schools as learning communities.
In China, which has the largest teaching force in the world, a long tradition of lesson study has been integrated into the professional lives of teachers. Since the 1950s, lesson study as a tool of professional learning facilitated the development of a culture of teaching among Chinese teachers. For the enhancement of their teaching and professional development, Chinese teachers are engaged in "teaching research", which is a form of lesson study organized along the disciplinary lines of school subjects and implemented by "teaching research groups" in schools. Indeed, lesson study is a commonly shared endeavor among Chinese teachers who are engaged in collective planning, studying and evaluating various kinds of lessons on a daily basis. Through time, the "teaching research group" has been developed into a system of "teaching research" that is unique to schooling in China.
In previous WALS annual conferences, educators and teachers from Asia, Australia, Europe, and North America came together to share their research findings and best practices in lesson study. This is the first time that WALS will hold its annual conference in Mainland China. WALS 2018 will provide a valuable opportunity for the exploration of ideas that will enrich the field of Lesson Study. We hope that participants from all over the world will come and share wisdom that is drawn from their own societal contexts and join us in an international dialogue that aims to achieve multi-cultural understanding of Lesson Study.
We cordially invite researchers, teachers and educators from all countries and regions to join us at the WALS 2018, which will be held on the campus of Beijing Normal University in Beijing, the capital of The People's Republic of China, during 23-26 November 2018.
Activities of the Conference will include keynote speeches, paper presentations,topical symposia, workshops, poster presentations, and school visits.
We are proud to announce that Professor Elaine Munthe of the University of Stavanger, Norway, Professor XudongZhu of Beijing Normal University, China, and Professor Jan Vermunt of the University of Cambridge, United Kingdom, have been invited to deliver keynote speeches at the Conference.
In addition to the keynote speeches, several plenary sessions will be organized for noteworthy scholars and practitioners in the field. These sessions will elucidate important topics that are relevant to teaching and learning in schools and universities as well as critical issues in special education, pre-school education, and large-scale educational development projects.
School visits in Beijing will be planned as a main activity on the final day of the conference.
II. Call for Proposals
1. Lesson study and teacher preparation
2. Lesson study and teacher professional development

2. Topical symposia (1.5 hours per session)
Interested participants may propose symposia for topics that are related to any of the aforesaid strands. 90 minutes will be allocated to each symposium. We anticipate 3 inter-related papers to be presented at a symposium. Symposium organizers should observe the deadline listed in the "Important Dates" below. They are also advised to appoint a chairperson and a discussant for each symposium session.
Examples of symposia
a. Researchers of common interests may wish to collaborate on a symposium that consists of 3 research papers covering inter-related topics.
b. A school may be interested to organize a symposium consisting of 3 presentations that draw professional insights from its school leaders and teachers.
c. Teachers serving in different schools may wish to present case studies of common interests.
3. Workshops (1.5 hours per session)
Workshops are informative, interesting and interactive sessions that are designed for general conference participants or for specific target-groups (e.g. teachers, school leaders, educators, researchers). Workshops may consist of hands-on activities, demonstration, and/or discussion. The topics of proposed workshops should be related to any of the aforementioned strands.
4. Poster presentation (1.5 hours per session)
Posters may include reports of ongoing research or case studies of professional practices. Research reports should clearly state the research topic, research question(s), and methods of data collection, data analysis and preliminary research findings. Posters of good practices should include such information as the background of school, context of case study, data analysis (where applicable), findings and recommendations. Presenters are advised to prudently use texts and graphics in the layout of their posters as space for display will be limited.

is the original IRC message hash like it is returned by parse_irc_msg.
error => $code, $message, $ircmsg
Emitted when any error occurs. $code is the 3 digit error id string from RFC 1459 or the string 'ERROR'. $message is a description of the error. $ircmsg is the complete error irc message.
You may use AnyEvent::IRC::Util::rfc_code_to_name to convert $code to the error name from the RFC 2812. eg.:
 rfc_code_to_name ('471') => 'ERR_CHANNELISFULL'
NOTE: This event is also emitted when a 'ERROR' message is received.
debug_send => $command, _USER_
Is emitted everytime some command is sent.
debug_recv => $ircmsg
Is emitted everytime some command was received.
$cl = AnyEvent::IRC::Client->new (%args)
This is the constructor of a AnyEvent::IRC::Client object, which stands logically for a client connected to ONE IRC server. You can reuse it and call connect once it disconnected.
NOTE: You are free to use the hash member heap to store any associated data with this object. For example retry timers or anything else.
%args may contain these options:
send_initial_whois => $bool
If this option is enabled an initial WHOIS command is sent to your own NICKNAME to determine your own ident. See also the method nick_ident. This is necessary to ensure that the information about your own nickname is available as early as possible for the send_long_message method.
$bool is false by default.
$cl->connect ($host, $port)
$cl->connect ($host, $port, $info)
This method does the same as the connect method of AnyEvent::Connection, but if the $info parameter is passed it will automatically register with the IRC server upon connect for you, and you won't have to call the register method yourself. If $info only contains the timeout value it will not automatically connect, this way you can pass a custom connect timeout value without having to register.
The keys of the hash reference you can pass in $info are:
 nick - the nickname you want to register as
 user - your username
 real - your realname
 password - the server password
 timeout - the TCP connect timeout
All keys, except nick are optional.
$cl->register ($nick, $user, $real, $server_pass)
Sends the IRC registration commands NICK and USER. If $server_pass is passed also a PASS command is generated.
NOTE: If you passed the nick, user, etc. already to the connect method you won't need to call this method, as AnyEvent::IRC::Client will do that for you.
$cl->set_nick_change_cb ($callback)
This method lets you modify the nickname renaming mechanism when registering the connection. $callback is called with the current nickname as first argument when a ERR_NICKNAMEINUSE or ERR_UNAVAILRESOURCE error occurs on login. The return value of $callback will then be used to change the nickname.
If $callback is not defined the default nick change callback will be used again.
The default callback appends '_' to the end of the nickname supplied in the register routine.
If the callback returns the same nickname that was given it the connection will be terminated.
$cl->nick ()
Returns the current nickname, under which this connection is registered at the IRC server. It might be different from the one that was passed to register as a nick-collision might happened on login.
$cl->is_my_nick ($string)
This returns true if $string is the nick of ourself.
$cl->registered ()
Returns a true value when the connection has been registered successful and you can send commands.
$cl->channel_list ()
$cl->channel_list ($channel)
Without $channel parameter: This returns a hash reference. The keys are the currently joined channels in lower case. The values are hash references which contain the joined nicks as key (NOT in lower case!) and the nick modes as values (as returned from nick_modes ()).
If the $channel parameter is given it returns the hash reference of the channel occupants or undef if the channel does not exist.
$cl->nick_modes ($channel, $nick)
This returns the mode map of the $nick on $channel. Returns undef if the channel isn't joined or the user is not on it. Returns a hash reference with the modes the user has as keys and 1's as values.
$cl->send_msg (...)
See also AnyEvent::IRC::Connection.
$cl->send_srv ($command, _USER_)
This function sends an IRC message that is constructed by mk_msg (undef, $command, _USER_) (see AnyEvent::IRC::Util). If the registered event has NOT yet been emitted the messages are queued until that event is emitted, and then sent to the server.
NOTE: If you stop the registered event (with stop_event, see Object::Event) in a callback registered to the before_registered event, the send_srv queue will NOT be flushed and NOT sent to the server!
This allows you to simply write this:
 my $cl = AnyEvent::IRC::Client->new;
 $cl->connect ('', 6667, { nick => 'testbot' });
 $cl->send_srv (PRIVMSG => 'elmex', 'Hi there!');
Instead of:
 $cl->reg_cb (
 registered => sub {
 $cl->send_msg (PRIVMSG => 'elmex', 'Hi there!');
$cl->clear_srv_queue ()
Clears the server send queue.
$cl->send_chan ($channel, $command, _USER_)
This function sends a message (constructed by mk_msg (undef, $command, _USER_) to the server, like send_srv only that it will queue the messages if it hasn't joined the channel $channel yet. The queued messages will be send once the connection successfully JOINed the $channel.
$channel will be lowercased so that any case that comes from the server matches. (Yes, IRC handles upper and lower case as equal :-(
Be careful with this, there are chances you might not join the channel you wanted to join. You may wanted to join _TAG_ and the server redirects that and sends you that you joined _TAG_. You may use clear_chan_queue to remove the queue after some timeout after joining, so that you don't end up with a memory leak.
$cl->clear_chan_queue ($channel)
Clears the channel queue of the channel $channel.
my (_USER_) = $cl->send_long_message ($encoding, $overhead, $cmd, _USER_, $msg)
As IRC only allows 512 byte blocks of messages and sometimes your messages might get longer, you have a problem. This method will solve your problem:
This method can be used to split up long messages into multiple commands.
$cmd and _USER_ are the IRC command and it's first parameters, except the last one: the $msg. $msg can be a Unicode string, which will be encoded in $encoding before sending.
If you want to send a CTCP message you can encode it in the $cmd by appending the CTCP command with a "\001". For example if you want to send a CTCP ACTION you have to give this $cmd:
 $cl->send_long_message (undef, 0, "PRIVMSG\001ACTION", "_TAG_", "rofls");
$encoding can be undef if you don't need any recoding of $msg. But in case you want to send Unicode it is necessary to determine where to split a message exactly, to not break the encoding.
Please also note that the nick_ident for your own nick is necessary to compute this. To ensure best performance as possible use the send_initial_whois option if you want to use this method.
But note that this method might not work 100% correct and you might still get at least partially chopped off lines if you use send_long_message before the WHOIS reply to send_initial_whois arrived.
To be on the safest side you might want to wait until that initial WHOIS reply arrived.
The return value of this method is the list of the actually sent lines (but without encoding applied).
$cl->enable_ping ($interval, $cb)
This method enables a periodical ping to the server with an interval of $interval seconds. If no PONG was received from the server until the next interval the connection will be terminated or the callback in $cb will be called.
($cb will have the connection object as it's first argument.)
Make sure you call this method after the connection has been established. (eg. in the callback for the registered event).
$cl->lower_case ($str)
Converts the given string to lowercase according to CASEMAPPING setting given by the IRC server. If none was sent, the default - rfc1459 - will be used.
$cl->eq_str ($str1, $str2)
This function compares two strings, whether they are describing the same IRC entity. They are lower cased by the networks case rules and compared then.
$cl->isupport ()
$cl->isupport ($key)
Provides access to the ISUPPORT variables sent by the IRC server. If $key is given this method will return its value only, otherwise a hashref with all values is returned
$cl->split_nick_mode ($prefixed_nick)
This method splits the $prefix_nick (eg. '+elmex') up into the mode of the user and the nickname.
This method returns 2 values: the mode map and the nickname.
The mode map

FRA, as the lead federal agency, will prepare an Environmental Impact Statement (EIS) to evaluate the potential impacts to the human and natural environment resulting from the Washington Union Station Expansion Project. FRA published the Notice of Intent (NOI) to prepare the EIS for the Project in the Federal Register on November 4, 2015.
The EIS will be developed in accordance with the Council on Environmental Quality (CEQ) regulations (40 CFR part 1500 et. seq.) implementing the National Environmental Policy Act (NEPA) of 1969 (42 U.S.C. 4321 et seq.) and FRA's Procedures for Considering Environmental Impacts (64 FR 28545, May 26, 1999). In addition to NEPA, the EIS will address other applicable statutes, regulations and executive orders, including the 1980 Clean Air Act Amendments, Section 404 of the Clean Water Act, the National Historic Preservation Act, Section 4(f) of the Department of Transportation Act, the Endangered Species Act and Executive Order 12898 on Environmental Justice. The EIS will provide the FRA, reviewing and cooperating agencies, and the public with information to assess alternatives that will meet the Project's purpose and need; evaluate the potential environmental impacts; and identify potential avoidance and mitigation measures.

Beowulf Theme of The Supernatural
The supernatural is definitely present in Beowulf, but it's oddly complicated. First, we have the two demons, Grendel and his mother, and the other assorted monsters of the epic – the dragon that Beowulf must fight, the serpentine creatures in the lake, and the sea monsters that Beowulf fought in the past. These are the stock monsters out of an epic fantasy tale. But Beowulf is also deeply conflicted about religion. The poet who composed the poem has a strongly Christian worldview, but also knows that the people he's telling a story about, who are from his distant past, would probably have been pagans. As a result, Beowulf fuses the supernatural together with a religious depiction of evil in a strange and interesting way – the monsters are the Biblical Cain's children.
Questions About The Supernatural
 1. Why are all the major antagonists in Beowulf depicted as supernatural creatures, demons, and monsters? How is the epic different with supernatural antagonists than it would be if the antagonists were human?
 2. How does your interpretation of Beowulf change if you interpret Grendel and his mother as human outcasts or members of a rival tribe, rather than as demonic monsters?
 3. The supernatural elements in Beowulf include demons, a dragon, and sea monsters. Is there a conflict between these fantasy elements and the theme of religion in the epic? To put it another way, can divine intervention and dragons co-exist easily in the same story?
 4. Does Beowulf himself seem to have any supernatural powers? (Hint: consider his exploits in the water, both in the swimming contest and in the lake where Grendel's mother lives.)
Chew on This
Instead of a conflict between straightforward good and evil, Beowulf depicts a conflict between demonic fantasy creatures and the power of fate wielded by a Christian God.
Because Beowulf himself seems to be stronger and have more stamina than a normal mortal man, he needs fantastic monsters as his opponents.

It's been another very quiet week on the Meadow. The main point of interest have been an increase in autumn birds with Meadow Pipits numbers noticeably up and Golden Plover now up to 75 birds, often to be seen wheeling around in the sky. There were also about half a dozen YELLOW WAGTAILS in amongst the cattle today. Lapwing are also regularly hanging out on the Meadow with up to fifty on some days. The warmer weather is offering a welcome reprieve for the summer insects after the cold snap and moth numbers in the trap are up again though for me it's been the same few species of late. The highlight of the week for me was finding a CLOUDED YELLOW in Burgess Field.

Chat with us, powered by LiveChat Judaism and Religious Beliefs Paper | acewriters
1. Discuss and briefly outline one way in which Judaism finds meaning. 2. Consider and explain what a few (at least two) of the other religious traditions we have discussed so far might say about the areas in which Judaism finds meaning. In particular, what do you think they would say about the relationship between the sacred and daily life (e.g., the Jewish Hallowing of Life)? Use examples and textual support from this Unit's readings and materials to help illustrate and support your ideas.3. Explain your own views concerning the meaning we can find in life. How does your view compare to that of Judaism's approach to meaning? How does it compare to the other religious traditions?

The following regex
var patt1=/[0-9a-z]+$/i;
extracts the file extension of strings such as
filename-jpg
filename#gif
filename.png
How to modify this regular expression to only return an extension when string really is a filename with one dot as separator ? (Obviously filename#gif is not a regular filename)
UPDATE Based on tvanofsson's comments I would like to clarify that when the JS function receives the string, the string will already contain a filename without spaces without the dots and other special characters (it will actually be handled a slug). The problem was not in parsing filenames but in incorrectly parsing slugs - the function was returning an extension of "jpg" when it was given "filename-jpg" when it should really return null or empty string and it is this behaviour that needed to be corrected.

 Does the regex have to determine if the filename is a legal filename? What defines a legal filename? What defines a legal filename extension? For example, is foo bar.zi_ a legal filename? How about foo.bar.zi_? – tvanfosson Jul 5 '11 at 12:06
 - The typical OS filename..your example with space in it cannot happen in our system and the answer provided by @stema seems to work with double extensions so it's good enough for me. – mare Jul 5 '11 at 12:11

 Both examples are legal file names in Unix and Windows. Your question could be improved by detailing exactly what you consider to be a legal filename. It will make the answers, esp. the accepted answer more meaningful to future readers who may be looking to solve the same or a similar problem. – tvanfosson Jul 5 '11 at 12:39

Just add a . to the regex
var patt1=/\.[0-9a-z]+$/i;
Because the dot is a special character in regex you need to escape it to match it literally: \..
Your pattern will now match any string that ends with a dot followed by at least one character from [0-9a-z].
Example:
[
 "foobar.a",
 "foobar.txt",
 "foobar.foobar1234"
].forEach( t =>
 console.log(
 t.match(/\.[0-9a-z]+$/i)[0]
 )
)
if you want to limit the extension to a certain amount of characters also, than you need to replace the +
var patt1=/\.[0-9a-z]{1,5}$/i;
would allow at least 1 and at most 5 characters after the dot.

 - what if I don't need the dot in my match and just the extension only? – user2727195 Sep 30 '16 at 22:38

 @user2727195 Without the dot, you're not matching an extension. If you mean... how do you use only the resulting text, then you could use substring, like so: ( ("file.ext").match(patt1) || '').substring(1); – Armstrongest Oct 5 '16 at 15:59
 - also fails for .tar.gz extension – Ravi Teja Feb 18 at 9:40
 - The code in the comment above didn't work for me. If you want just the extension, not the dot, do... const ext = ("file.ext".match(/\.[0-9a-z]{1,5}$/i) || [""])[0].substring(1) – chichilatte 21 hours ago

Try
var patt1 = /\.([0-9a-z]+)(?:[\?#]|$)/i;
This RegExp is useful for extracting file extensions from URLs - even ones that have ?foo=1 query strings and #hash endings.
It will also provide you with the extension as $1.
var m1 = ("filename-jpg").match(patt1);
alert(m1); // null
var m2 = ("filename#gif").match(patt1);
alert(m2); // null
var m3 = ("filename.png").match(patt1);
alert(m3); // [".png", "png"]
var m4 = ("filename.txt?foo=1").match(patt1);
alert(m4); // [".txt?", "txt"]
var m5 = ("filename.html#hash").match(patt1);
alert(m5); // [".html#", "html"]
P.S. +1 for @stema who offers pretty good advice on some of the RegExp syntax basics involved.

Example list:
var fileExtensionPattern = /\.([0-9a-z]+)(?=[?#])|(\.)(?:[\w]+)$/gmi
//regex flags -- Global, Multiline, Insensitive
var ma1 = 'css/global.css?v=1.2'.match(fileExtensionPattern)[0];
console.log(ma1);
// returns .css
var ma2 = 'index.html?a=param'.match(fileExtensionPattern)[0];
console.log(ma2);
// returns .html
var ma3 = 'default.aspx?'.match(fileExtensionPattern)[0];
console.log(ma3);
// returns .aspx
var ma4 = 'pages.jsp#firstTab'.match(fileExtensionPattern)[0];
console.log(ma4);
// returns .jsp
var ma5 = 'jquery.min.js'.match(fileExtensionPattern)[0];
console.log(ma5);

ONELINER:
let ext = (filename.match(/\.([^.]*?)(?=\?|#|$)/) || [])[1]
above solution include links. Egzamples (filename -> ext):
// "abcd.Ef1" -> "Ef1"
// "abcd.efg" -> "efg"
// "abcd.efg?aaa&a?a=b#cb" -> "efg"
// "abcd.efg#aaa__aa?bb" -> "efg"
// "abcd" -> undefined
// "abcdefg?aaa&aa=bb" -> undefined
// "abcdefg#aaa__bb" -> undefined
It takes everything between last dot and first "?" or "#" char or string end. To ignore "?" and "#" characters use /\.([^.]*)$/. To ignore only "#" use /\.([^.]*?)(?=\?|$)/.
