The panel will enable the projectors to produce a bright image of 4096 x 2160 pixels resolution (2160p), which is four times the resolution of a top range high definition television or Blu-Ray Disc. Epson’s panel is a 4K compatible HTPS (high temperature polysilicon) TFT (thin film transistor) liquid crystal panel for 3LCD projectors. The panel measures only 1.64 inches (4.2 cm) along the diagonal. The images have outstanding contrast and brightness, and rich vibrant colors.The panel uses a C2 Fine LCD, which is a technology invented by Epson that combines an inorganic liquid crystal alignment layer with a vertical alignment layer.3LCD projectors have three separate LCD panels: one each for red, green and blue light. The single color light passes through the LCD panel that creates shades of the color. The single color images are then combined by a prism to create a full color image that is projected onto the screen via the projector lens. Because the 3LCD technology has no moving parts in the light control system the projected image is smooth, sharply detailed, and there is no break-up in the motion or color.The new panels may mean 3LCD projectors will find application in replacing the large, expensive projectors used for digitally projecting film in cinemas, for industrial and corporate presentations, and in schools and at big events. They will also be ideal for applications such as industrial and architectural design and simulations requiring high resolutions. The 4K panels can also be used to project four full HD images simultaneously.A prototype of a projector using the 4K panel will be exhibited at the International Broadcast Equipment Exhibition at Makuhari Messe, Chiba, in Japan from 18 to 20 November, 2009. It is not known when the panel will be released to the market.More information: Seiko Epson Press Release (Japanese)© 2009 PhysOrg.comlast_img read more

Ecological burial involves freezedrying composting the corpse

first_img © 2010 PhysOrg.com (PhysOrg.com) — Ever since the 12th century, the most common way to bury the dead has been to lay the corpse in a casket and then bury the casket several feet underground. Since then, we have learned that casket burials cause environmental and health problems due to the fact that the corpses do not receive enough oxygen to quickly decompose into compost. Instead, the corpses undergo a slow rotting process by bacteria that feed on sulfur, and remaining products can harm the nearby drinking water. More information: www.promessa.org.uk and Promessa’s Facebook pagevia: io9 Promessa founder Susanne Wiigh-Mäsak has developed an ecological burial process that allows the body to be restored to the earth as naturally as possible. Image credit: Promessa, Niklas Johansson. Citation: Ecological burial involves freeze-drying, composting the corpse (2011, March 8) retrieved 18 August 2019 from https://phys.org/news/2011-03-ecological-burial-involves-freeze-drying-composting.html A Swedish company called Promessa Organic AB thinks there is a better way to lay the dead to rest. The company’s founder, biologist Susanne Wiigh-Mäsak, has developed an ecological form of burial in which the corpse is transformed into compost in about 6-12 months. The organic burial process avoids embalming fluids and greatly reduces the environmental impact on the air, water, and soil.The first part of the ecological burial method involves removing the water that makes up 70% of the human body. To do this, the company freeze-dries the corpse in liquid nitrogen within a week and a half after death. The corpse is first frozen to -18°C (0°F) and then submerged in liquid nitrogen. Next, sound waves at a specific amplitude vibrate the brittle corpse, transforming it into an organic white powder. The powder is sent through a vacuum chamber that evaporates the water, greatly decreasing the corpse’s mass. If the person had metal surgical implants, a metal separator can remove these parts from the dry powder. If required, the powder can also be disinfected.At this point, the organic powder is hygienic and odorless, and the remains can either be cremated or buried. Since the powder will not decompose if kept dry, there is no hurry for a burial. At the time of burial, the remains are laid in a coffin made of a biodegradable material such as corn starch and placed in a shallow grave. Depending on the wishes of the next of kin, a bush or tree can be planted above the coffin. Within 6-12 months, both the coffin and its contents will become loam, a high-nutrient soil that nourishes the plant growing above. As Promessa’s website notes, this process “can instill greater insight in and respect for the ecological cycle, of which every living thing is a part. The plant stands as a symbol of the person, and we understand where the body went.”Wiigh-Mäsak, who owns a greenhouse and grows 15,000 organic plants, had been thinking about the idea of an ecological burial for many years until she finally decided to develop the idea into a reality.“The calm hours spent in my greenhouse gave me peace of mind, and it suddenly become obvious to me how human beings could also be fully integrated with the natural ecological cycle that we are an inherent part of,” she writes on Promessa’s website.Promessa has won awards from the Green Organisation as well as received recognition from UNESCO for the environmental benefits of the Promession process.Currently, the company is building its first facility to offer ecological burial as an alternative to casket burial. The first Promatorium in Sweden should open in the spring of 2011, with additional facilities to follow in the UK and South Korea.

Physicist creates scale model of LHC ATLAS experiment of out LEGO blocks

first_img(PhysOrg.com) — The Large Hadron Collider at the European Organization for Nuclear Research (CERN) in Switzerland has generated a lot of news of late, e.g. the announcement that a team had found what it believes to be a particle that traveled faster than he speed of light, an actual new particle, and of course the seemingly never-ending storyline associated with the hopeful discovery of the elusive Higgs Boson, now a physicist not associated with the project, has built a scale model replica of the ATLAS experiment; a particle detector that will likely serve as ground zero should the so-called “god particle” ever be observed. The Large Hadron Collider is a type of cyclotron, or particle accelerator. It’s hollow and circular, sort of like a giant hula-hoop and sits underground where particles are made to run faster and faster inside of it using very powerful magnets. The ATLAS experiment sits at one point on the circle and allows researchers the ability to watch as particles go whizzing by. The hope is that in observing particles moving at high speeds or when they collide, that new discoveries about the nature of the universe will be made.The real ATLAS project is 44 meters long and 22 meters wide and weighs 7000 tonnes. Mehlhase’s model, at approximately 1:50 scale is approximately 1 meter long by a half meter wide. And while the real deal has millions of parts, the model has 9500 pieces, mostly LEGO blocks. Mehlhase first tried to model the ATLAS on computer, but then apparently found the undertaking untenable. Abandoning that approach, he set to work replicating the ATLAS by simply mimicking what it looked like. His wife and some students helped sort the blocks, but he alone assembled the model, which he says he tried to model as closely as one could using simple plastic bricks. To give some perspective, he modeled some tiny physicists as well.Mehlhase says he’s contacted LEGO (a Danish company) in hopes of having his model included as one of the model kits sold by the company, though he hasn’t yet made a manual. He’d like to see similar models constructed in schools all over the world.The finished product, an obvious labor of love, is now on display at the Institute.

The point of building the replica, he says, is to incite interest in physics. Plus, no doubt, it was sort of fun. © 2011 PhysOrg.com Explore further This document is subject to copyright.

New magnetic cataclysmic variable star discovered

first_img Citation: New magnetic cataclysmic variable star discovered (2016, October 3) retrieved 18 August 2019 from https://phys.org/news/2016-10-magnetic-cataclysmic-variable-star.html (Phys.org)—A new magnetic cataclysmic variable (CV) star has been detected by astronomers in the constellation of Draco. The newly found object, designated DDE 32, exhibits a large amplitude variability with one of the shortest orbital periods – about 100.5 minutes. The findings are reported in a paper published Sept. 27 on the arXiv pre-print server. CVs are binary star systems consisting of a white dwarf and a normal star companion. They irregularly increase in brightness by a large factor, then drop back down to a quiescent state. One subclass of CVs, called polars, comprises cataclysmic variables with strong magnetic fields. DDE 32 was found to be such a polar, with the accretion mode changing from one pole to two poles.DDE 32, first identified by the ROSAT space observatory as an X-ray source in December 2007, was initially designated 1RXS J161935.7+524630. At the moment of its detection, the nature of this source was unclear and it was considered to be too red for a cataclysmic variable. Therefore, its re-classification was neglected for nearly four years.Now, Denis Denisenko of the Moscow State University in Russia and Fabio Martinelli of the Lajatico Astronomical Centre in Pisa, Italy, have re-designated 1RXS J161935.7+524630 to DDE 32, revealing its magnetic cataclysmic variable behavior. Their conclusion was based on the follow-up observations conducted since 2011 and on the analysis of the data collected by the Sloan Digital Sky Survey (SDSS).”Despite the 10-years-long experience in identifying X-ray sources and finding cataclysmic variables by many different methods, this one has deceived me at first and escaped the correct identification for several years,” Denisenko told Phys.org.The researchers revealed that DDE 32 is a new polar with an orbital period of nearly 0.07 days (100.5 minutes) and changing geometry of accretion. The object experiences a large amplitude (nearly 2 magnitudes) variability and its accretion mode changed from one pole before 2014 to two poles in 2015.”Every cataclysmic variable has its own ‘cataclysms’ and its own unique way of changing behavior with time. Of course, DDE 32 is not the first CV known to change accretion regime from one pole to the other, or to both poles at once. But it is one of the systems like that with the shortest period, and it’s changing the shape of light curve on rather short time scales. It is those quick changes that make it very useful in understanding the processes in cataclysmic binaries,” Denisenko noted.However, many parameters of DDE 32 are yet to be determined, especially when it comes to the system’s white dwarf. At the moment, the scientists don’t know its mass, magnetic field, and even rotation period.Moreover, DDE 32 needs to be assigned to one of several polar subtypes: AM Her (“classical” polars), BY Cam (asynchronous polars) and DQ Her (intermediate polars). Further studies are required to measure the rotation period of the polar’s white dwarf in order to verify its classification.”I have made some hypotheses that proved to be wrong with time and with more data becoming available. Since I have limited access to the state-of-art astronomical equipment, especially to the spectroscopic one, I encourage the more detailed study of those objects that stand out from the general CV population. Even if those studies will ultimately prove I was wrong,” Denisenko concluded. © 2016 Phys.org The mysterious cataclysmic variable star Mu Centauri (Update) This document is subject to copyright.

More information: 1RXS J161935.7+524630: New Polar with the Varying Accretion Modes on two Magnetic Poles, arXiv:1609.08511 [astro-ph.SR] arxiv.org/abs/1609.08511AbstractWe report the discovery of a new cataclysmic variable DDE 32 identified with the ROSAT X-ray source 1RXS J161935.7+524630 in Draco. The variability was originally found by D. Denisenko on the digitized Palomar plates centered at the position of X-ray source. The photometric observations by F. Martinelli at Lajatico Astronomical Center in June 2015 have shown the large amplitude (nearly 2 magnitudes) variability with a period about 100.5 minutes. Using the publicly available Catalina Sky Survey data from 2005 to 2013 we have improved the value of period to 0.0697944 days. Comparison of the archival CRTS data with more recent observations from Lajatico shows the dramatic changes in the light curve shape. Instead of a single peak present in Catalina data before 2014, there were two peaks of nearly the same height during 2015. SDSS spectrum taken in June 2009 shows prominent Helium emission lines between the bright Balmer series. He II 4686 AA line has more than 30% effective width compared to H_beta line. All those features allow us to interpret 1RXS J161935.7+524630 as a magnetic cataclysmic variable (polar) with the accretion mode changing from one pole before 2014 to two poles in 2015.

Chief Minister Mamata Banerjee has ordered the police to immediately arrest Arabul, in connection with the incident. State Election Commissioner A K Singh has sought an immediate report from the police in this connection.During an interview in a television channel, Banerjee, while responding to a poser on the Bhangar incident, said, “Some Maoists have been camping in the area and causing unrest. The police administration has been directed to take steps,” she said. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedA large police force, led by the Superintendent of Baruipur Police District, rushed to the spot and conducted raids at various places to nab the assailants.The independent candidate whose rally was attacked, was backed by Jomi Jibika Rokkha Bahini (Land and Livelihood Protection Force), leading to a stir against a power grid station at Bhangar. Bhangar has often been on the boil since January 2017, with Arabul Islam and his supporters clashing repeatedly with the villagers participating in the agitation against land-acquisition for the power grid. Police suspect that the agitation has the support of ultra-Left group Red Star. Many of its members were arrested under UAPA.Nine independents from Bhangar had filed their Panchayat nomination via WhatsApp, as they had claimed that they could not go to nomination centres due to fear of attacks.last_img read more

Transport dept sees revenue generation climb north

first_imgKolkata: The state Transport department has witnessed a rise in revenue generation in the first four months of thecurrent fiscal, as a result ofsustained drives to collect arrears.The drives have been taken up to ensure that car owners follow the motor vehicle rules strictly. This has resulted in the hike in revenue generation as well.According to the sources in the state Transport department, the revenue generation against motor vehicle tax and others including vehicle registration fees, driving licence fees, fine against overloading, etc. was Rs 2,292 crore in the 2017-18 financial year. Also Read – Rain batters Kolkata, cripples normal lifeIt shows that the average collection per month in the last fiscal was Rs 191 crore. “The same has further gone up in the first four months of the current financial year and the average revenue generation now is Rs 210 crore per month. There has been a revenue generation of Rs 840 crore in the first four months of the 2018-19 fiscal,” said a senior official of the department.It may be mentioned that the revenue generation during the Left Front regime in the 2011-12 fiscal was Rs 960 crore. With several drives taken up by the state Transport department, the same has gone up to Rs 2,292 crore in the 2017-18 fiscal. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedAccording to the officials of the state Transport department, steps have been taken up to ensure compliance of the motor vehicle rules. Notices are being sent urging to clear the arrears and subsequent moves are also being made in case the same is not cleared despite sending notices. “It is expected that the revenue generation would touch Rs 2,500 crore by the end of the 2018-19 financial year,” said an official.Stringent measures have been taken against overloading of goods and the motor vehicle inspectors (MVIs) maintain a vigil to check the same. Around 200 MVIs will join the existing strength in September. With the increase in revenue generation, the state Transport department has taken several measures and improved infrastructure in the state’s Transport sector.Besides adding 1,200 new buses in the past seven years, the department has extended financial support to the police in creating necessary infrastructure to check road accidents as a part of the Safe Drive Save Life campaign.Around 2,500 state-run buses used to ply in the state in 2011. The number has gone up to 3,200, despite around 100 buses that plied for more than 15 years or 8 lakh kilomtres, being scrapped. Moreover, e-buses and CNG buses have also been introduced.Interestingly, the erstwhile Left Front government used to take loan to buy buses that had led to a debt of Rs 132 crore. Now, the state Transport department procures the buses from its planned budget.last_img read more
