New type of nuclear fission discovered

first_imgThe experimental apparatus with which Otto Hahn and Fritz Strassmann discovered nuclear fission in 1938. Image: Wikipedia. The nucleus of mercury-180 contains 80 protons and 100 neutrons, and symmetrical fission would result in two nuclei of zirconium-90, which contains 40 protons and 50 neutrons. This result was expected to be dominant especially because 50 and 40 are magic and semi-magic numbers respectively, meaning the levels in the nucleus would be completely filled with protons/neutrons.Andrei Andreyev, of the University of the West of Scotland in Paisley, and colleagues carried out the experiments at the ISOLDE facilities at CERN. These facilities enable physicists to work with pure beams of highly unstable heavy elements and collect their reaction products and analyze them. They began with a beam of the highly unstable thallium-180, which has 81 protons and 99 neutrons, and which decayed primarily by the capture of an electron to convert one of the protons into a neutron, giving the 80 protons and 100 neutrons of mercury-180. This should then theoretically split symmetrically.Instead, the mercury isotope split into ruthenium-100, with 44 protons and 56 neutrons, and krypton-80, with 36 protons and 44 neutrons. These are isotopes with incompletely filled energy levels. Asymmetric splitting has been seen previously in isotopes of uranium, which often split into the isotope tin-132 and a smaller fragment. The tin-132 has all energy levels in the nucleus filled, with 50 protons and 82 neutrons, and is an extremely stable isotope. This asymmetric fission was therefore easy to explain, but the new findings cannot be explained in this way, and this is the first time such unexplainable fission has been observed.The researchers then analyzed the energy requirements for different types of mercury-180 splitting, and found less energy was required for the asymmetric split found experimentally than for the symmetrical split predicted by the theory. Team member Piet Van Duppen of the Catholic University of Leuven in Belgium, said this may mean other isotopes in the same area of the periodic table may also split into asymmetric daughter fragments. Another isotope of mercury has now been tested, and it also split asymmetrically.The results of the experiments highlight the gap in the scientific knowledge of nuclear fission, which still cannot be fully described in detail some seven decades after the process was discovered. The gap may be filled in as new radioactive beam facilities become available in the next few years, including the Facility for Antiproton and Ion Research in Germany and the Facility for Rare Isotope Beams in the US.The experimental results of the experiments are published in Physical Review Letters. (PhysOrg.com) — Nuclear fission, or the splitting of a heavy nucleus, usually results in symmetrical fragments of the same mass. Physicists attribute the few known examples of fission that is asymmetric to the formation in the resultant fragments of “magic” nuclei, which are extremely stable nuclei with all energy levels filled. Now, experiments at the European particle physics laboratory at the Organization for Nuclear Research (CERN) near Geneva in Switzerland have found the isotope mercury-180 splits asymmetrically into ruthenium-100 and krypton-80 rather than the expected zirconium-90.

Researchers find trees worldwide more sensitive to drought than previously thought

first_imgImage: Wikipedia. Explore further More information: Global convergence in the vulnerability of forests to drought, Nature (2012) doi:10.1038/nature11688AbstractShifts in rainfall patterns and increasing temperatures associated with climate change are likely to cause widespread forest decline in regions where droughts are predicted to increase in duration and severity1. One primary cause of productivity loss and plant mortality during drought is hydraulic failure2, 3, 4. Drought stress creates trapped gas emboli in the water transport system, which reduces the ability of plants to supply water to leaves for photosynthetic gas exchange and can ultimately result in desiccation and mortality. At present we lack a clear picture of how thresholds to hydraulic failure vary across a broad range of species and environments, despite many individual experiments. Here we draw together published and unpublished data on the vulnerability of the transport system to drought-induced embolism for a large number of woody species, with a view to examining the likely consequences of climate change for forest biomes. We show that 70% of 226 forest species from 81 sites worldwide operate with narrow (<1 megapascal) hydraulic safety margins against injurious levels of drought stress and therefore potentially face long-term reductions in productivity and survival if temperature and aridity increase as predicted for many regions across the globe5, 6. Safety margins are largely independent of mean annual precipitation, showing that there is global convergence in the vulnerability of forests to drought, with all forest biomes equally vulnerable to hydraulic failure regardless of their current rainfall environment. These findings provide insight into why drought-induced forest decline is occurring not only in arid regions but also in wet forests not normally considered at drought risk7, 8.Press release (Phys.org)—A multinational team of researchers has found that trees worldwide are more sensitive to drought than scientists realized. By analyzing data on trees around the world, the teams has, as they write in their paper published in the journal Nature, found that even small changes in precipitation can lead to large numbers of tree deaths. In a perspective piece in the same journal, German researcher Bettina Engelbrecht says the teams' results indicate that trees of all regions could be in trouble as global temperatures rise, not just those in drier climates. Citation: Researchers find trees worldwide more sensitive to drought than previously thought (2012, November 22) retrieved 18 August 2019 from https://phys.org/news/2012-11-trees-worldwide-sensitive-drought-previously.html © 2012 Phys.orgcenter_img Journal information: Nature To find out how sensitive trees in general are to changes in precipitation amounts, the research team studied data from 226 trees located in 81 sites around the world. Specifically, they looked at the point at which trees begin suffering from what is known as hydraulic failure. Trees pull water from the soil by means of evaporation in their leaves. As water moves out of the leaves, a vacuum is created in the channels (xylem) that bring water up from the roots into the plant, which serves to pull water up into the tree from the soil. If less water is available than the plant needs, air bubbles begin to accumulate in the xylem, plugging them. If enough channels become plugged, the tree suffers hydraulic failure and dies.In analyzing the available data, the researchers discovered that approximately 70 percent of the trees they studied lived near the point of failure. This they say is because trees adapt to their surroundings by developing in such a way as to suck up just the right amount of water they need to survive, while at the same time, competing with other plants in the area for other resources such as sunlight. This means, Engelbrecht, writes, that even trees in wet regions are at risk of dying off if rainfall amounts change even a little bit.The researchers suggest that rainfall amounts worldwide are likely to change as the world heats up due to global warming. Some areas are expected to get more water, others less. This new research suggests that those places that get less, even just a little, are likely to see widespread tree die-offs.

A way to speed up reaction discoveries using automation

Journal information: Science More information: Snap deconvolution: An informatics approach to high-throughput discovery of catalytic reactions , Science  14 Jul 2017: Vol. 357, Issue 6347, pp. 175-181, DOI: 10.1126/science.aan1568 , http://science.sciencemag.org/content/357/6347/175AbstractWe present an approach to multidimensional high-throughput discovery of catalytic coupling reactions that integrates molecular design with automated analysis and interpretation of mass spectral data. We simultaneously assessed the reactivity of three pools of compounds that shared the same functional groups (halides, boronic acids, alkenes, and alkynes, among other groups) but carried inactive substituents having specifically designed differences in masses. The substituents were chosen such that the products from any class of reaction in multiple reaction sets would have unique differences in masses, thus allowing simultaneous identification of the products of all transformations in a set of reactants. In this way, we easily distinguished the products of new reactions from noise and known couplings. Using this method, we discovered an alkyne hydroallylation and a nickel-catalyzed variant of alkyne diarylation. Schematic representation of experimental design and analysis. Credit: Science  14 Jul 2017: Vol. 357, Issue 6347, pp. 175-181 © 2017 Phys.org Discovering new chemical reactions with useful applications is generally a laborious process. It typically involves combining large groups of reagents two at a time with a catalyst then studying the molecular makeup to see what might be useful—the more experiments conducted, the more likely chemists will find something new and useful. This situation is unfortunate, because the discovery of new reactions leads to the development of new products. This is why some chemists seek ways to automate at least some of the process. In this new effort, the researchers describe a technique that involves the use of a gas chromatography/mass spectrometry GC/MS device, a sealed 96-well plate, and a slew of spreadsheet macros.In general, the new technique involves loading up the wells with reactants, adding different amounts of ligand and metal combinations, and heating them to 100°C for 18 hours. That is followed up by using GC/MS to observe changes in each of the wells and analyzing the results using spreadsheet macros. More specifically, the technique involves starting with just three compounds divided into pools that belong to the same type of molecular function group. Before the reactions are induced, inert substitutes are added, each varying in mass. When the reactions occur, the unique mass of each allows for easy detection by GC/MS and subsequent analysis using the macros.The researchers report that their technique speeds up the process used for discovering useful new reactions by a factor of three by automating some of the time-consuming steps. They claim it works as advertised, noting that they used it to discover a three-component, nickel-catalyzed diarylation of alkynes.center_img (Phys.org)—A pair of researchers with the University of California and Lawrence Berkeley National Laboratory has found a way to automate reaction discoveries, thereby speeding up the process.

Charlottesville Victims Use PostSlavery KKK L

first_imgCharlottesville Victims Use Post-Slavery KKK Law To Go… Steve Helber by NPR News Hannah Allam 8.28.19 3:40pm Liz Sines happened to be near campus that night, so she was among the first to see the hundreds of young men who stormed the University of Virginia lawn. They marched in the darkness, tiki torches illuminating their faces as they chanted ugly slurs: “Jews will not replace us!”Sines said the chaos of that weekend in Charlottesville, Va., two years ago this month means that some memories are blurry. Others, she said, are so vivid she couldn’t forget them if she tried. There was the fiery arrival of the white nationalists that first night; violent clashes the next day, with activists opposing them; and then the horrifying sound of a car coming down a hill and into the crowd where Sines was standing.She realized it wasn’t an accident when she saw the driver back up to roll over more bodies.”That’s when it clicked,” Sines said. “It very much seemed like he was going to try and kill as many people as possible.”The Unite the Right rally in Charlottesville came to symbolize a turning point in the nation’s understanding of its racial extremism problem. Sines was a witness to that moment, and now she’s a plaintiff in an unusual lawsuit that seeks to hold the rally organizers accountable for the violence that culminated in the car attack that killed 32-year-old Heather Heyer and wounded 30 others.The driver of the car eventually got life in prison. But what about the extremists who organized the rally? Only a handful faced criminal charges; most went unpunished. Sines and nine others who experienced the violence that weekend are suing the two dozen extremists and hate groups they say orchestrated the rally.The plaintiffs suffered injuries, trauma, loss of work and other lingering problems from the ordeal. The defendants are leaders in the white nationalist movement, and the ultimate goal of the civil suit is to put them out of business.”The message is that if you conspire to attack innocent people, to attack innocent people of color, to attack Jewish people, then you will be held accountable,” Sines said.The lawsuit claims that the violence associated with the rally was not spontaneous — leaked messages show that events had been meticulously planned months in advance on the social media platform Discord.”They talked about everything, from what to wear, what to bring for lunch. For instance, they speculated on whether mayo would spoil in the sun,” said Amy Spitalnick, executive director of Integrity First for America, a nonprofit backing the lawsuit.And, she said, organizers made clear they expected violence.”They talked about which weapons to bring, cracking skulls and even whether they could claim self-defense if they drove cars into protesters, which is, of course, exactly what happened,” Spitalnick said.To make their case, the plaintiffs’ legal team is reaching back — way back — to invoke a law from 1871. It’s known as the Ku Klux Klan Act, a post-slavery attempt by Congress to protect newly emancipated black people from vigilante attacks by the KKK.”It’s not a frequently used statute in the sense that, frankly, 150 years after it was first passed, it’s stunning that we need to use it still,” Spitalnick said. “But it is exactly relevant here.”The approach is novel — and it’s a gamble.Jack Beermann, a law professor at Boston University who has written extensively about the KKK Act, agreed that what happened in Charlottesville is exactly the kind of racist violence that Congress wanted to prevent with the act. However, he said, the Charlottesville lawsuit faces an “uphill climb” because the Supreme Court historically has been averse to applying that law to racial violence carried out by private citizens.Still, Beermann said, the suit is important no matter the outcome because of the evidence it has uncovered about the workings of hate groups.”This lawsuit has served to show that what we have is a very organized, very cohesive and very dangerous group of white supremacist organizations in the United States,” he said.The plaintiffs’ legal team said there is “powerful” precedent for this application of the 1871 law. And so far the judge has agreed, rejecting motions to dismiss the suit and allowing it to proceed to trial based on “very persuasive guidance” from earlier cases involving similar 13th Amendment issues.”We are confident that the law is on our side and that the men and women we represent will obtain the justice they so clearly deserve,” said the plaintiffs’ attorney, Joshua Matz, who specializes in constitutional law.Apart from the legal questions, there are security and logistical concerns involved with going after violent neo-Nazis.Spitalnick said calling the extremists uncooperative is an understatement. One defendant made violent anti-Semitic threats against the legal team. Others have failed to comply with the court-ordered discovery process. Even some of the defendants’ lawyers appear to have had enough; in court papers, attorneys for two extremists asked for permission to drop their clients, saying they’d fallen out of touch or had engaged in “repugnant or imprudent” conduct.”The defendants have really gone to outrageous lengths to try to undermine this case,” Spitalnick said. “They have failed to turn over phones and computers and accounts. One even claimed that his phone fell in the toilet.”Attorneys for the defendants didn’t respond to NPR’s requests for comment. One defendant, Kyle Chapman, representing himself, responded via email. He denied involvement and called the lawsuit a miscarriage of justice by “verminous cretins.”Sines, the law student turned plaintiff, said the lawsuit shows a clear-cut conspiracy to sow racist violence, and she believes the judge will agree. She’s now 25, and she just graduated from law school. She’s starting a new life, in a new town she prefers not to name for security reasons.Sines said she’s still figuring out her place in the legal profession; her experience in Charlottesville has shown her the possibilities — and limitations — of trying to change society through the courts.”We’re using laws that are now over a century old to take down white nationalists,” she said. “Again.”Copyright 2019 NPR.

Appeasing one and all Impossible

first_imgIn a Sunday that brought a bouquet of films from different eras, the romance with cinema continued with flair at Siri Fort. The auditorium brimmed with energy for a workshop and panel discussion on We: the offended. The crux of the debate was to discuss the allegations, ranging from gender bias to stereotyping sects, posed at films from different fronts, pre and post release. As often is the case with these panel discussions, the auditorium seemed to be living the back-story of the cinema. There’s a lot more to what one sees on the silver screen: cuts, provocations, allegations, bans et al. The moot point for the day was offence. Also Read – ‘Playing Jojo was emotionally exhausting’Moderating the discussion, the Chief executive officer of CBFC Pankaja Thakur welcomed the panelists, directors- Rakeysh Omprakash Mehra, Ketan Mehta, Luv Ranjan, Rajendra Singh Babu, legal expert Amit Nayak and professor of Cinema studies at JNU, Ira Bhaskar. The afternoon session opened with Rakeysh Omprakash Mehra’s story of Dilli 6. How it got embroiled with the SC ST commission over the portrayal of a waste picker. As the discussion picked up, it was noted that films get stuck before release due to a lot more reasons than censor board’s obstructions. With a country of over a billion, it’s difficult to appease everyone, it seems. Mehra shared the quagmire Also Read – Leslie doing new comedy special with NetflixRang de Basanti found itself in, when the ministries found it uncomfortable to portray the crash of MiG 21. The audience was in splits listening to his ‘moment of shake’, when he said, ‘My legs were shaking when I screened it to ministers and chiefs of forces in Delhi, not because I was concerned about the ban on the film.  But who gets a chance to screen one’s movie to a gathering of that sort.’ Mehra was later honored at the 75 years of celebration of air force for his efforts. He confesses that one cannot cross the line under the garb of creativity. That was a one-off remark coming from a director of his stature. In the wake of restraining orders on movies like Vishwaroopam and the likes, from the legal front, Amit Nayak talked of constitutional provisions that do not allow pre censorship of a film before its exhibition after once it is certified by the censor board.Though the discussion didn’t allow for a fair share of interaction with the audience, in the last few minutes, questions were pointed towards lack of representation of SC/ST commission, animal welfare boards or any such bodies  on the panel that block the passage of films post certification. We also felt that their take could add another layer to the panel discussion. Luv Ranjan the director of Pyar ka Panchama gauged the sentiments and appropriately summed up that everything is bound to offend somebody or the other. The trouble accentuates when you do not want to discus the problem. For that one sentiment, at a small level, the panel discussions at Siri Fort are allowing for a responsible exchange of ideas on things unsaid and unheard about the movies. While filmmakers rued the role certain factions play in threatening and harassing their creativity; they also lauded the role of censor board that has moved on from being an autocratic censor board to a certifying authority, open to dialogue. The last question for the evening popped up a relevant take on Indian cinema while it celebrates its 100 years with a huge fanfare: When would Indian cinema go beyond its national issues to reflect upon a global theme? With an off the cuff, ‘Why not!’ Mehra wrapped up the discussion. Perhaps, the answer lies in the films that will probably be prompted by such discussions.last_img read more

State government mulls mat hub in Vidyasagar Industrial Park

first_imgKolkata: The state government is planning to come up with a mat (madur) hub at the Vidyasagar Industrial park in Kharagpur, to give a big boost to the industry. A portion of the land at the industrial park has already been earmarked for setting up the proposed hub.Sabang in West Midnapore, located at a distance of less than 40 kilometres from Kharagpur, is known for churning out mats of international quality, which are acclaimed all over the world. More than 55 percent of the total mat production in the country comes from the Sabang block, which has 13 gram panchayats under it.More than 90 percent of the population in Sabang earns a livelihood by manufacturing mats. A village haat (fair) held every Tuesday in Sabang witnesses people from all parts of the state, including the neighbouring states of Odisha and Jharkhand.”Chief Minister Mamata Banerjee is familiar with every nook and cranny of Sabang and she is patronising the development of the mat industry. The push given by the state government has ensured that the artisans involved in the manufacture of these mats face no difficulty in getting bank loan. There are 16 nationalised bank branches in Sabang block at present,” said Trinamool Congress MP Manas Bhuniya, who had been a six-time elected MLA from Sabang.When Bhuniya was the state Cottage and Small Scale Industries minister, the Bengal government in 2012 launched the “Natural Fibre Mission” and included the development of skill of artisans and supply of tools and equipment for rural people associated with making products from natural fibres like jute, bamboo, coir, mat, sabai grass, cotton and silk.Several rural haats were conceived and gradually the condition of the people involved with the industry improved. “The Centre has stopped funds for this progamme, but the initiative and interest of the Chief Minister has kept the ball rolling in the state,” he added.Bhuniya’s wife Gita Rani, who is an MLA from Sabang, is also in talks with some NGOs to boost the marketing of the mats. The state government will soon come up with two ‘Karmatirtha’ in Sabang, which will contribute to further development of the industry.The Bengal government had hosted the first edition of Madur (Mat) Mela, solely dedicated to mat weavers, on Digha sea beach in January.last_img read more

Private hospital in New Town faces power cut due to rain

first_imgKolkata: A private hospital meant for children in New Town witnessed power cut following heavy rainfall on Tuesday.According to sources, as the basement of the hospital got waterlogged, the metre room was flooded. Electricity had to be disconnected as it could have caused short-circuit, leading to an untoward incident.Since Tuesday evening, the power had gone off at the hospital. Later, it was restored only in some portions of the hospital. To ease the problem, the hospital authority shifted a good number of patients to their Park Street branch within a short period of time. Several guardians of the patients were agitated. Later, the hospital authority restored power in the portion where patients were staying with the help of a generator.

It happened to other major buildings in New Town as well on Tuesday.””Due to unnatural rain on Tuesday, the water went down to our basement. After being informed, the authority helped us. As a security measure, connection was cut off. Though it can be restored, we are not doing it before the basement area gets totally dry,” said Bijay Dwibedi, a high ranked official from the hospital authority on Wednesday.last_img read more

Theme of maya to shape pandal of North Kolkata Puja committee

first_imgKolkata: The theme of this year’s Durga Puja of Purba Kalikata Sarbojanin Durgotsab Committee of Narkeldanga in North Kolkata is maya, the central theme of Indian philosophy.Conceptualised by artist Swapan Sarkar, the lighting arrangement has been made by Saurabh Sanyal to implement the theme. The idol has been made by Sanatan Paul. Noted music director Kalyan Sen Barat has composed the theme music. Fishing net, poles of different sizes made by bamboo and human palms made of plaster of Paris symbolising invitation of people to the non-permanent virtual world will be put up as the theme’s design elements. Work is going on round the clock to complete the pandal. “Our only problem is the unpredictability of rain. We have covered the entire area where the artisans are giving final touches to the pandal and to meet the deadline, bright sunny days are needed,” said Subhrokanti Lodh, the spokesperson of the committee. The lights will create special effects and that will create an ambience of a virtual world. “We have selected the theme as only real knowledge can help us to get over violence and jealousy which have affected society. During Durga Puja we pray for peace and prosperity and an end of evil,” said Lodh. The community puja will enter its 72nd year in 2018. The main thoroughfare near the pandal was closed for many years due to the construction work of East-West Metro. The road has now been thrown open to traffic. The organisers feel that several people will visit the pandal and appreciate the theme and ambience. Maya is the most important concept in Indian philosophy. “The world is illusory because it is non-permanent. The world around is like a “snake-rope” illusion. People see a rope and take it to be a snake. They fail to see the non-permanence of the world because of ignorance, which is dispelled only when true knowledge comes. Because of ignorance there is shameless ego and people tend to differentiate on the basis on caste, creed, sex and religion. Real knowledge refines individuals and the Upanishads have asked people to follow the path of true knowledge,” are some of the tenets of the concept. Lodh said: “To save people from the destructive traits, the knowledge of the real world is needed and we will use the platform of Durga Puja to create awareness on this among the people.”last_img read more

Agriculture dept set to ramp up production of Tulaipanji rice in North

first_imgKolkata: The state Agriculture department is all set to cultivate Tulaipanji rice on a much larger scale in North Dinajpur district. The use of paddy transplanter machine on a pilot basis for sowing the seeds of the indigenous rice variety on a 3 acre land at Kalua in Hemtabad has resulted in 20 percent more production of the variety.”From next year, we will use the technology for large-scale cultivation of this rice variety in Chopra and Itahar. The process of identifying the areas for cultivation is on. The variety is suited to grow in places adjacent to the river, as the location is congenial for the aroma of the rice,” a senior official of the Agriculture department said. Also Read – Rain batters Kolkata, cripples normal lifeIt may be mentioned that the demand for rice varieties like Tulaipanji and Gobindobhog is high throughout the country. The use of the paddy transplanter technology was started in August this year and till November, the production has seen an increase of 20 percent. Tulaipanji is cultivated in the Raiganj, Kaliaganj, Hemtabad and Karandighi blocks of Uttar Dinajpur district and Kushmandi block of Dakshin Dinajpur district. However, the production is lesser than the demand, as a result of which the price is beyond what common people can afford. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killed”Chief Minister Mamata Banerjee has instructed us to take measures to ensure that aromatic varieties like Tulaipanji and Gobindobhog come within the reach of common people. For this, we have to increase production”, state Agriculture minister Asish Banerjee said. As per figures available with the district administration of North Dinajpur, Tulaipanji was cultivated on 6,700 hectares in 2017-18, compared to 5,400 hectares in 2016-17 and 4,600 hectares in 2015-16, registering a growth of 45 percent in three years. The production of Tulaipanji has also gradually gone up. From 10,120 million tonnes in 2015-16 to 14,740 million tonnes in 2017-18 in the district. “We are in constant touch with the North Bengal Agriculture University and seeking their opinion in boosting cultivation of Tulaipanji in North Bengal. We have already started the cultivation of both Tulaipanji and Gobindobhog in certain areas of Malda,” Banerjee said. Gobindabhog rice, which is primarily cultivated in East Burdwan’s Raina, is also being cultivated in Sagar and Patharpratima in South 24-Parganas and parts of Bankura district.last_img read more
