The paper can be tuned on and off. In the off position, the wallpaper is indistinguishable from any other wall covering surface. His work has been on display in Amsterdam at the Design Scoops during September, 2007. His next exhibit will be October 20-28 at Dutch Design Week in Eindhoven, Netherlands. Mr. Samson has received favorable reviews by Fengshangweekly dot com, and Trendhunter dot com.Jonas Samson explores the utility, art and craft of turning conventional items into a work of high tech design. In his other work he utilizes a process called Freestyle Blowmoulding to produce works of art and utility from standard industrial products. These products can be produced with speed and accuracy.The Freestyle Blowmoulding is achieved by pressing air into PVC tubes and pre-formed tubes that are from the halved soda bottles to create works of art and consumer products. The range of products include, trendy jug containers, vases and other home products. Each design that is created is unique, but may be massed produced. The art form is the result of the combined efforts of art, craft and commercial utility. The finished product is in part controlled by the production process that may involve a level of chance. This slight level of unpredictability creates the uniqueness of the objects of art.

Dust involved in sulfate production in clouds

first_img Journal information: Science Cirrus clouds form around mineral dust and metallic particles, study finds Citation: Dust involved in sulfate production in clouds (2013, May 10) retrieved 18 August 2019 from https://phys.org/news/2013-05-involved-sulfate-production-clouds.html Explore further The research team, led by Eliza Harris of the Max Planck Institute for Chemistry in Germany, determined that sulfates are formed within clouds by oxidation of sulfur dioxide on the surface of coarse mineral dust particles. The oxidation is catalyzed by metal ions within the dust particles.Mineral dust particles are released into the atmosphere by human activities such as intensive agricultural practices and deforestation, while metallic particles are released through industrial combustion processes, including the burning of fuels containing lead.It was previously thought that sulfates were primarily formed in clouds through the action of peroxide formed during photochemical reactions, but the new study shows that this is a less dominant process. The researchers were able to show this because the two oxidation routes favor different isotopes of sulfur, and by examining the ratio of isotopes in sulfur dioxide entering clouds and sulfates in the clouds, they were able to demonstrate that the mineral dust/metal ion route was the dominant one.The findings are important because sulfates in clouds are thought to increase cloud formation and light scattering by clouds, both of which have a cooling effect. Peroxides and mineral dusts have different distributions across the globe, and so assuming that peroxide was the dominant route led to incorrect assumptions about the production of sulfates in different regions. The findings that relatively large particles are involved also means the sulfates do not stay in the clouds as long as previously thought since they are formed on relatively large particles that easily drop out. This means the influence of sulfates and the cooling associated with them has been overestimated.A second study, led by atmospheric scientist Dan Cziczo of the Massachusetts Institute of Technology (MIT), studied ice formation in cirrus clouds, which typically form several kilometers above the ground, and found that ice nucleation had occurred around specks of mineral dust or metallic particles in the clouds. Dr. Harris, who is now also at MIT, said it was interesting that the two studies had been published at the same time, and both should help to refine the climate models, which currently do not adequately take into account the importance of mineral dust and its effects on the climate. © 2013 Phys.orgcenter_img More information: Harris, E. et al. Enhanced role of transition metal ion catalysis during in-cloud oxidation of SO2, Science Vol. 340, 727-730, doi: 10.1126/science.1230911 , Published May 10th, 2013.ABSTRACTGlobal sulfate production plays a key role in aerosol radiative forcing; more than half of this production occurs in clouds. We found that sulfur dioxide oxidation catalyzed by natural transition metal ions is the dominant in-cloud oxidation pathway. The pathway was observed to occur primarily on coarse mineral dust, so the sulfate produced will have a short lifetime and little direct or indirect climatic effect. Taking this into account will lead to large changes in estimates of the magnitude and spatial distribution of aerosol forcing. Therefore, this oxidation pathway—which is currently included in only one of the 12 major global climate models—will have a significant impact on assessments of current and future climate.Press release (Phys.org) —A new study from Germany has studied the tiny dust particles within clouds and their influence on the climate.

Holographic lens printing method could allow printing of telescope lenses in space

The content is provided for information purposes only. (Phys.org)—Researchers have developed a method for printing optical holographic lenses that could greatly simplify their fabrication. Because the method can be performed quickly and easily, it could potentially be used by astronauts to print lenses while in space for holographic lens telescopes. More information: Qiancheng Zhao, et al. “Printable Nanophotonic Devices via Holographic Laser Ablation.” ACS Nano. DOI: 10.1021/acsnano.5b03165 Group webpage: HB-Nanophotonic Group at the University of Birmingham Explore further The researchers, led by Dr. Haider Butt at the University of Birmingham in the UK, along with coauthors from there and the Harvard Medical School and Wellman Center for Photomedicine at Massachusetts General Hospital in the US, have published a paper on the new holographic lens printing method in a recent issue of ACS Nano.”Using the novel technique of holographic laser ablation, which we previously used for printing holograms, we have demonstrated the printing of optical lenses made of a variety of materials,” Butt told Phys.org. “A complete lens can be fabricated with a single nanosecond laser pulse. Hence the method is fast, flexible, and inexpensive.”While current holographic lens fabrication methods are often expensive, time-consuming, and labor-intensive, the new printing method can produce a lens in just a few seconds using only a single step. The method uses a nanosecond laser pulse to create interference patterns on a transparent substrate coated with light-absorbing materials. The laser is reflected off a concave mirror back onto itself, so that interference occurs between two laser beams traveling in opposite directions. The resulting interference pattern, consisting of circular fringes, is “printed” on a substrate between the two beams, storing the optical information as a holographic lens. The resulting flat, ultra-thin lenses consist of hundreds of nanoscale circular zones that contribute to focusing light.Using this new method, the researchers demonstrated that they could achieve mass production within a few minutes. The method should also work with a wide variety of materials on substrates that are semitransparent, with geometries that are flat, curved, or of other arbitrary form. Besides having niche applications like printing telescope lenses in space, the new printing method could also be used for security, data storage, and biosensors. Due to the flexibility of the fabrication method, lenses can be printed on certain materials that are not compatible with conventional fabrication techniques. In the future, the scientists plan to use the method to print lenses on thin films of semiconductors, with applications in applied optics and infrared imaging.

Hybridization generates a hopeful monster: a hermaphroditic selfing cichlid, Royal Society Open Science (2016). DOI: 10.1098/rsos.150684AbstractCompared with other phylogenetic groups, self-fertilization (selfing) is exceedingly rare in vertebrates and is known to occur only in one small clade of fishes. Here we report observing one F1-hybrid individual that developed into a functional hermaphrodite after crossing two closely-related sexually reproducing species of cichlids. Microsatellite alleles segregated consistent with selfing and Mendelian inheritance and we could rule out different modes of parthenogenesis including automixis. We discuss why selfing is not more commonly observed in vertebrates in nature, and the role of hybridization in the evolution of novel traits. The team reports that they were studying chichlid fish and at one point bred two different species of the fish, resulting in the birth of several offspring, only one of which later developed male reproductive organs. Such fish, they note reproduce by mixing sperm and egg sin the mouth. In this instance, it appeared that the hybrid ejected sperm into the water and then sucked it into its mouth where it fertilized the eggs that were waiting there. The fish shortly thereafter gave birth to several offspring. Also, the team reports, it was not a onetime occurrence, the fish self fertilized itself many times over the course of a year, giving birth to 42 offspring (both male and female) of which it was both the mother and father. The offspring all appeared normal and reproduced without any of them resorting to selfing. They did all suffer, however, from what scientists call inbreeding depression, where there is minimal genetic diversity, which can lead to birth defects in subsequent generations. Having two genders it is believed was an evolutionary development that came about to allow for genetic diversity, after all.Selfing is not unheard of in the animal kingdom, other species such as mangrove killifish engage in it as part of their normal reproductive habits—but in their case, it is one born of necessity when there are no potential mates around—it is also an adaption that came about out of necessity. The researchers believe the selfing observed in the cichlid female likely came about due to its parents having different sex-determining genes, and that it was almost certainly an oddity, and thus not likely to happen again anytime soon. They note also that it is not likely that this was the first occurrence of selfig in the species, such instances have likely gone underreported due to its rarity. (Phys.org)—A female cichlid hybrid fish has been observed to have grown male reproductive organs, impregnate itself and then to have offspring, a team of researchers in the U.K. are reporting in a paper published in the journal Royal Society Open Science. They call the process ‘selfing’ and suggest it is very rare in vertebrates. This document is subject to copyright.

Blind quantum computing for everyone

first_img(Phys.org)—For the first time, physicists have demonstrated that clients who possess only classical computers—and no quantum devices—can outsource computing tasks to quantum servers that perform blind quantum computing. “Blind” means the quantum servers do not have full information about the tasks they are computing, which ensures that the clients’ computing tasks are kept secure. Until now, all blind quantum computing demonstrations have required that clients have their own quantum devices in order to delegate tasks for blind quantum computing. The team of physicists, led by Jian-Wei Pan and Chao-Yang Lu at the University of Science and Technology of China, have published a paper on the demonstration of blind quantum computing for classical clients in a recent issue of Physical Review Letters.”We have demonstrated for the first time that a fully classical client can delegate a quantum computation to untrusted quantum servers while maintaining full privacy,” Lu told Phys.org.The idea behind blind quantum computing is that, while there are certain computing tasks that quantum computers can perform exponentially better than classical computers, quantum computing still involves expensive, complex hardware that will make it inaccessible for most clients. So instead of everyone owning their own quantum computing devices, blind quantum computing makes it possible for clients to outsource their computing tasks to quantum servers that do the job for them. Ensuring that the quantum computing is performed blindly is important, since many of the potential applications of quantum computing will likely require a high degree of security.Although several blind quantum computing protocols have been performed in the past few years, they have all required that the clients have the ability to perform certain quantum tasks, such as prepare or measure qubit states. Eliminating this requirement will provide greater access to blind quantum computing, since most clients only have classical computing systems. In the new study, the physicists experimentally demonstrated that a classical client can outsource a simple problem (factoring the number 15) to two quantum servers that do not fully know what problem they are solving. This is because each server completes part of the task, and it is physically impossible for the servers to communicate with each other. To ensure that the quantum servers are performing their tasks honestly, the client can give them “dummy tasks” that are indistinguishable from the real task to test their honesty and correctness. The researchers expect that the new method can be scaled up for realizing secure, outsourced quantum computing, which could one day be implemented on quantum cloud servers and make the power of quantum computing widely available.”Blind quantum computing protocol is an important privacy-preserving technique for future secure quantum cloud computing and secure quantum networks,” Lu said. “Applying our implemented blind quantum computing protocol, classical clients could delegate computation tasks to servers ‘in the cloud’ blindly and correctly without directly owning quantum devices. It saves resources and makes scalable quantum computing possible.”In the future, the physicists want to make blind quantum computing even easier for clients by further reducing the requirements.”We plan to study more robust blind quantum computing protocols with fewer required resources and fewer constraints theoretically and experimentally,” Lu said. “We will also explore blind quantum computing for more application scenarios, such as multi-user blind quantum computing, publicly verifiable quantum computing, and secure multi-party quantum computing.” This document is subject to copyright.

Credit: Rachel Golden Kroner Explore further For much of modern history, governments and national leaders have set aside land under their jurisdiction to prevent it from destruction by human activities. But as the researchers note, governments are also free to remove such restrictions if they so desire. In this new effort, the researchers studied the history of land protection and protected area downgrading, downsizing and degazettement, or PADDD, over the past two centuries.The researchers report that they found that approximately 2 million square feet of land around the world has been PADDDed, since 1892. Furthermore, they found that approximately 78 percent of that land downgrading has occurred over just the past 20 years. In their report, they focused most strongly on PADDDing in the U.S. and Amazonia. They found that approximately 90 percent of the land downgraded in the U.S. over the past two centuries happened over just the past 20 years. And sadly, approximately 99 percent of such land was downgraded so that it could be used for industrial purposes. More information: Rachel E. Golden Kroner et al.

Credit: Rachel Golden Kroner The researchers suggest that the trend of removing restrictions from protected lands could have an impact on other countries looking to shore up their economies, leading to removal of restrictions in other countries.More optimistically, Naughton-Treves and Buck Holland suggest that rather than look at downgraded land totals, environmentalists need to look at how land is being used. They note that while there is generally more biodiversity inside of protected areas than out, there are other factors at play as well. One such factor, they point out, is the impact that protecting wildlands has on people living in the area—especially poor people. In many areas, the result is great hardship. They also note that the degree of harm brought to downgraded areas depends very much on the types of industries that come in. Some, they note, such as extractive industries, are particularly damaging. They suggest that local entities should be the ones making land protection decisions rather than remote entities, allowing more thoughtful management of valuable land.

Observations reveal gas stripping and enhanced star formation in the galaxy JO206

first_imgThe VLA Hi column density contours overlaid on the V-band image of JO206 from WINGS (V-band image from Moretti et al. 2014). Credit: Ramatsoku et al., 2019. Explore further At about 85 billion solar masses, JO206 is a massive “jellyfish” galaxy hosting an active galactic nucleus (AGN) and a member of the IIZw108 galaxy cluster at a redshift of approximately 0.049. The so-called jellyfish galaxies have one-sided tails seemingly stripped from the galaxy’s main body.In the case of JO206, astronomers have assigned the highest jellyfish morphological classification of 5.0 as it showcases the most recognizable tail of debris material that is apparently stripped from the main body. The stripped tail of material is thought to be the result of ram-pressure stripping due to the intra-cluster medium (ICM) of IIZw108.Studies of jellyfish galaxies, in particular the examination of star formation activity during the process of gas stripping, could be crucial in improving the understanding of galactic evolution in general. One method of such studies is the investigation of neutral atomic hydrogen (HI) in these galaxies.Recently, a team of astronomers led by Mpati Ramatsoku of the Astronomical Observatory of Cagliari in Italy used this technique to study JO206. The research was focused on the galaxy’s long tail of ionized gas and how this feature affects the interstellar medium, as well as star formation activity. The observational campaign was carried out using the VLA telescope as part of the GAs Stripping Phenomena survey (GASP).”As part of the ESO MUSE GASP survey, we have studied the HI gas phase of the prototypical ‘jellyfish’ galaxy in the sample, namely, JO206,” the astronomers wrote in the paper.According to the study, the neutral atomic hydrogen distribution in JO206 is perturbed and exhibits a one-sided HI tail from the optical disc. The tail extends over 293,000 light years and has an HI mass of about 1.8 billion solar masses. This means that the tail’s neutral gas mass currently constitutes about 60 percent of the whole galaxy’s HI mass.The research found that JO206 is generally undergoing an enhanced star formation activity compared to similar galaxies with the same stellar mass. JO206’s HI depletion time was estimated to be 500 million years, which is shorter than that of ordinary spiral galaxies observed to date.Moreover, the astronomers detected a strong correlation between the observed cold gas and ionized emission in JO206, seen both in the galaxy main body and the tail. “This indicates a strong link between the presence of cold gas and the recent star formation across all of the galaxy,” the scientists concluded.In addition, the study also found that that the star formation efficiency in the disc of JO206 is on average about 10 times higher compared to the tail for a given HI surface density. The researchers noted that in general, the inner and outer parts of JO206 have relatively higher star formation efficiencies compared to other galaxies in the literature.Summing up the research, the authors of the paper concluded that JO206, at its current stripping stage, still has fuel to form new stars along its tail and disc. “Comparing this galaxy with others in the GASP sample in different environments will clarify whether the environment played a pivotal role in the enhanced observed star formation or whether other specific physical conditions are responsible,” the astronomers wrote. Using the Very Large Array (VLA), astronomers have conducted observations of neutral gas in the galaxy JO206. Results of these observations provide important information regarding gas stripping and enhanced star formation in this galaxy.

The Wandering art

first_imgVarious artists from all across the Indian subcontinent came together to showcase their works in Delhi and brought in forgotten flavours of South Asia.The show, curated by Batasha Mathur and Kiran Chaudhary at Experimental Art Gallery, was inaugurated with a special preview for the capital’s glitterati on Saturday. The main attraction of the show were the scintillating art works from India, Bhutan and Pakistan. About 20 artists contributed, including  K Ravi, Arun Pandit, Sanjay Bhattacharya, Karma, Imrana Tanveer, Vijay Kalyan, Gopi Gajwani, Mashkoor Raza, K Balamurli, to name a few. Works of Indian painter Vaikuntam and Pakistani artist Salman Farooqi were admired the most by the visitors, who were equally chramed by the scenic portraits by the former and the anguished women by the latter. Also Read – ‘Playing Jojo was emotionally exhausting’Farooqi’s work has been intensely inspired by a genre dealing with an intimate perception of landscapes and cityscapes. He has held many group and solo shows in different cities of Pakistan and the Middle East. In some of his works, we found images of dark interiors with old-style table, chairs and ornately carved head board set against bright sunlight coming in through open windows.  Juxtaposed with this were the various feminine expressions that invoked corresponding dark moods.Vaikuntam’s paintings capture simple lifestyle of villagers, the paddy fields, toddy pots on shoulders of men, the household chores, temple rituals depicting rural life of the country. Colour palette for some paintings were bold shades of red, blue, black whereas some had pastel shades of yellow, blue, saffron and more.last_img read more

Cranberry juice may protect against killer diseases

first_imgDrinking low calorie cranberry juice cocktail may help lower the risk of chronic diseases, including heart disease, diabetes and stroke, says a study.The World Health Organisation estimates the trio of diseases annually claim 15.6 million lives around the globe. Cranberries provide a rich source of protective compounds   called polyphenols that support our body’s natural defences and help us achieve a balanced lifestyle to improve health. Also Read – ‘Playing Jojo was emotionally exhausting’To find the effectiveness of polyphenol-rich cranberries, researchers from the United States Department of Agriculture (USDA) provided eight weeks’ worth of meals to 56 healthy adult volunteers (average 50 years of age).“At the start and end of the experiment, the researchers measured things like blood pressure, blood sugar levels, blood lipids, as well as C-reactive protein, a marker of inflammation,” said Christina Khoo, director of Research Sciences at Ocean Spray. One group drank a glass of low-calorie cranberry juice twice daily. The other group drank a placebo beverage with a similar colour and flavour. Also Read – Leslie doing new comedy special with NetflixIndividuals drinking two glasses of low-calorie cranberry juice a day improved across all these measures.

Take the stairs to slow brain ageing

first_imgClimbing the stairs can not only help you stay physically fit but also improve brain health, suggests new research.“There already exist many ‘Take the stairs’ campaigns in office environments and public transportation centres,” said lead researcher Jason Steffener from Concordia University in Montreal, Canada.“This study shows that these campaigns should also be expanded for older adults so that they can work to keep their brains young,” said Steffener. The researchers found that education also played a positive role in brain health. Also Read – ‘Playing Jojo was emotionally exhausting’The study, published in the journal Neurobiology of Aging, showed that the more flights of stairs a person climbs and the more years of school a person completes, the “younger” their brain physically appears.For the study, Steffener and his co-authors used magnetic resonance imaging (MRI) to non-invasively examine the brains of 331 healthy adults who were aged between 19 to 79. They measured the volume of grey matter found in participants’ brains because its decline, caused by neural shrinkage and neuronal loss, is a very visible part of the chronological aging process. Then, they compared brain volume to the participants’ reported number of flights of stairs climbed and years of schooling completed.“This is encouraging because it demonstrates that a simple thing like climbing stairs has great potential as an intervention tool to promote brain health,” Steffener said.last_img read more

Govt mulls mechanism to directly alert common people about lightning strikes

first_imgKolkata: The state government is taking initiatives to ensure that lightning alert reaches common people directly in the grassroot level.It may be mentioned that the state Disaster Management and Civil Defence department has introduced a state-of-the-art technology in early 2018 that predicts lightning and information gets disseminated 45 minutes before it strikes. But at present, the information gets disseminated only among concerned officials of all ranks, including the district authorities. In districts, representatives of Gram Panchayats also get the messages in this regard. Also Read – Rain batters Kolkata, cripples normal lifeNow, in a bid to make the system more effective, the necessity of a mechanism has been felt so that the lightning alert messages reach common people in the grassroot level as well and they can go to a safe place. Explaining the situation, a state government official said that the system that was developed in collaboration with an expert company from USA, can send out an alert 45 minutes before the possibility of lightning in a particular block. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedImmediately, the messages get disseminated among the concerned officials up to the Gram Panchayat level and then the officials in districts take initiative to pass the same to the masses. “But it will be more effective if the same message can reach common people directly in the form of SMS, etc.” the official said, adding that there was a meeting in this regard with concerned agencies a few days ago. The messages have to be sent specifically only to those who reside in the block where there is possibility of lightning and the matter has been discussed in the meeting to find a way out. There will be further meetings in this connection. It may be mentioned that 294 people were killed due to lightning in 2016-17. It may be mentioned that lightning has claimed lives in the last monsoon as well. But, introduction of the mechanism to generate alert message 45 minutes before lightning strikes a particular area, has helped to make many people aware of the same in the last monsoon, helping them get to safety in time.last_img read more

Politics inseparable from Street theatre

first_imgPolitics cannot be separated from street theatre as it is not just defined by its art but also by its intent, according to veteran thespians Sudhanva Deshpande and Moloyashree Hashmi.At the fourth edition of ‘Lila’s Prism lecture series’, the talk titled ‘Jan Natya Manch: Shaping a pocket (the resistance)’ was about introducing people to the nitty-gritties of street theatre group and how Janam made the medium as its own.Founded in 1973, Jana Natya Manch (People’s Theatre Front; Janam for short) is a New Delhi-based theatre company. Having done some 8,500 performances of nearly 100 plays, the group specialises in left-wing street theatre in Hindi. Also Read – Add new books to your shelf“Street theatre is about giving primacy to politics. Don’t do street theatre if you don’t have politics. We at Janam don’t define it just by its form, but also by its intent. Its biggest resource is imagination of audience,” said Deshpande, actor and director with Janam.But making sure that people don’t decipher his message wrong, he added, “Please remember it cannot be sloganeering alone too. Only sloganeering and attempting to run a message down people’s throat has neither worked before, nor will it work in future.”  Also Read – Over 2 hours screen time daily will make your kids impulsiveWhile distinguishing street play from other forms, he says that it is an exact opposite of a play which has Naseeruddin Shah acting, who everyone admires and loves. “You like Naseeruddin Shah and you want to watch him. In street plays it is just the opposite. You don’t know us, forget about liking. On the contrary, we interrupt your life by performing in the middle of the road. Also, here we want you to watch us. You vote by your foot in this case,” said Deshpande. The group is known for taking on capitalism, deep-rooted patriarchy, and communalism through plays like ‘Halla Bol’, ‘Machine’, ‘Woh Bol Uthi’, ‘Aurat’ and ‘Dil Maange more Guru ji’.“When people ask don’t you feel scared about the things you say so openly in your play, I tell them that we have our plays in bastis (villages), industrial areas and in the so called down-trodden areas. Police and people with power, they don’t come to such places. And hence we are safe,” said Moloyashree, veteran theatre artiste and President of Janam. The evening also saw both talking about Founder of Janam Safdar Hashmi and his vision that is reflected in all the plays made under the group’s banner. An actor, director and communist playwright Hashmi was murdered in 1989,while performing his famous street play ‘Halla Bol’.“Safdar was someone unique. Can you believe he and Rakesh Saxena wrote ‘Machine’ in a single day. He could see the future. He was always there to perform for workers and would do all that he could to support their movement,” said Moloyoshree, wife of Safdar who to her credit have had performed ‘Machine’ over 1000 times now.Deshpande, who is also author of the book ‘Theatre of the streets: The Jan Natya Manch Experience’ was very blunt in saying that “art can’t change the world, especially if it’s a Bollywood movie.” He emphasized on the definition of artist and said: “You should understand that an artist is no solitary genius. He is no creator. He is just an intermediary who gives what he takes from society. It’s just that the form is different.” When asked about pedagogy and how to make sure that an actor is politically sensitised, Deshpande said, “Make them witness the lives of people living in the margins by walking through the streets of villages.“This is what we do with our actors while we are in the process of making plays, and it works,” he added.The Lila Lecture series includes 13 seminal conversation spread across August to December 2016 featuring 30 trailblazing practitioners of alternative institution-building.last_img read more
