(PhysOrg.com) — China tested a 500 kilometers per hour (311 mph) train over the weekend. Government officials call the record-breaking speedster a “useful reference” for China’s current high speed railway operations. The test train’s speed, according to a Monday report in China Daily, exceeds the world speed record of 300 kilometers per hour held by the Beijing Shanghai High Speed Railway. China’s latest high-speed train has a maximum tractive power of 22,800 kilowatts, compared with the 9,600 kilowatts for China Railways High-Speed (CRH) trains in service on the Beijing-Shanghai High Speed line. China denies safety lax on high-speed rail link Explore further © 2011 PhysOrg.com The train tested over the weekend is made of plastic materials reinforced with carbon fiber.The design concept is inspired by China’s ancient swords. The train’s designer and manufacturer is Sifang Locomotive, a subsidiary of China’s largest rail-vehicle maker, CSR Corp Ltd., based in Qingdao in eastern Shandong province. Last year, Technology Review carried details of the WuGuang line trains, variants of Japan’s Shinkansen and Germany’s InterCity Express high-speed trains. That line clocked impressive speeds. A rail expert at the New Jersey Institute of Technology in Newark at the time noted that high-speed rail technology implemented in China was not entirely different from the world’s TGV, ICE, and Shinkansen systems. What was notable about China’s high-speed lines was that the system was designed from the ground up for very high-speed operation over hundreds of kilometers. China has the largest network of bullet-train track in the world. The push for a massive buildout began in 2006 and continues, with the help of government stimulus funds. Miles of line are planned to the tune of billions to accommodate a future vision of over 16,000 kilometers of dedicated high-speed rail lines connecting all of China’s major cities by 2020. China’s engineering triumphs, however, have been hindered by troubles, highly publicized in the world press. The Chinese Railways Ministry Chief, Liu Zhijun, in charge of the construction of the high-speed railway massive network, was arrested for corruption. Then came reports that corruption had sacrificed safety concerns in a haste to roll out the high-speed rails. There were stories of substandard materials used to cut costs. The New York Times reported that the concrete bases for the tracks were made with insufficient hardening agents. The tracks could possibly warp, according to the report. Safety concerns, however, seem to be top of mind in the government after the July incident where 40 people died when two bullet trains crashed into each other in Zhejiang province.Officials felt it necessary to lower operating speeds on its bullet trains whereas trains with top speeds of 350 kh would be lowered to 300 kilometers peer hour, and trains designed for 250 would instead run at 200 kilometers per hour.Similarly, Chinese officials in the latest announcement are careful to point out that future Chinese trains will not necessarily run at such high speeds as that demonstrated in the newly tested superfast train. The CSR chair Zhao Xiaogang told the Beijing Morning News that “We aim to ensure the safety of train operations.” Citation: China tests 500 kilometers per hour train (2011, December 27) retrieved 18 August 2019 from https://phys.org/news/2011-12-china-kilometers-hour.html This document is subject to copyright.

(Phys.org) —A combined team of researchers from Newcastle University and the University of Glasgow, both in the U.K. has found that stress in young starlings can lead to shortened telomeres—which prior research has suggested leads to faster aging and development and behavioral problems later on in life. In their paper published in Proceedings of the Royal Society B, the team describes how they stressed young starlings and then tested them to see what it might have done to them. More information: Developmental telomere attrition predicts impulsive decision making in adult starlings, Proceedings of the Royal Society B: rspb.royalsocietypublishing.or … .1098/rspb.2014.2140Press release Prior research has found that telomeres—the caps on the ends of chromosomes—become shorter each time cells divide. Scientists have also found that it’s this shortening that causes aging in humans and other animals—and aging related illnesses such as diabetes, artery disease, some cancers and premature death. Other research has shown that shortening of telomeres doesn’t happen at the same pace in every species or even in the same species, which explains why some animals seem to age faster or slower than others of their kind. In this new effort, the researchers found that the process can be speeded up by stress—at least in young starlings.The researchers removed starling chicks from their nests and placed them in other nests, some with more hatchlings, others with less. Living with more hatchlings has been found to be more stressful for chicks as they have to compete more hardily for scarce resources from the mother. In testing the chicks 14 months later, the researchers found that those that had been placed in the more stressful nests had shorter telomeres. They also tested them for impulsiveness using delayed feeding techniques. Those raised in the more stressful nest, turned out to be more impulsive—they tended to go for immediate small meal rewards rather than wait a little longer for a much bigger reward.The team suggests their findings may be transferable to humans, as telomere length in people has been linked to both aging and impulsiveness as well. They believe that it’s likely that stress while young (due to a harsh or unpredictable home environment) can lead to premature aging and impulsiveness as a young adult, and likely age related illnesses later on in life.

A team of researchers with the Broad Institute of Harvard and MIT has found evidence showing that using base editors can lead to unexpected RNA cellular edits. In their paper published in the journal Science Advances, the group describes their study of the CRISPR type of adenine base editor (ABE), and what they found. ABEs convert one DNA base pair into another, allowing for the repair of mutations in some cell types without generating undesired editing effects. It is believed that ABEs also have the potential to correct almost half of all known genetic abnormalities that lead to medical disorders. The science underlying ABEs has become increasingly important to the medical community. Unfortunately, some very recent studies have found indications that ABEs might also be engaging in unexpected editing. This past March, a team found that the cytosine base editor 3 induced single-nucleotide variants at a higher-than-normal rate. And last month, another team discovered that cytosine base editors and ABEs result in off-target editing in RNA. In this new effort, the researchers sought to further test for off-target edits when using ABEs and to find a solution if it was confirmed.In their work, the researchers analyzed the newest version ABE called ABEmax in a way that included all cellular RNA transcripts in a human cell line—and they did it with more sensitive tools than others had used. They report that they did find low levels of undesired edits in RNA samples. To get around the problem, the team developed new variant ABEs (based on inactivated wild-type Escherichia coli) that retained their ability to make the desired base edits but caused less RNA editing. They further report that the new variants were created in a way that decoupled the RNA and DNA editing process, which minimized off-target editing in both DNA and RNA. The researchers conclude by noting that because of low levels of RNA editing and the short half-life of RNA, the degree of interference in future endeavors will likely depend on the specific applications in which they are used. They recommend that researchers seeking to minimize RNA editing use the new variant they created—they have called it ABEmaxQW. © 2019 Science X Network Explore further CRISPR base editors can induce wide-ranging off-target RNA edits More information: Holly A.

Kolkata: Academicians, historians and film lovers have approached the West Bengal Heritage Commission to include Nimtita Rajbari in Murshidabad where film Jalsaghar, one of Satyajit Roy’s award-winning iconic films was shot.A letter containing the signatures of more than 100 people has been submitted to the state Heritage Commission requesting it to enlist the building and save it from destruction.The Nimtita Rajbari was set up over 150 years ago and is situated on the banks of River Bhagirathi where massive erosion is taking place. Many structures situated close to the house have already been washed away. The locals said unless steps are not taken now, the building will have a similar fate. Also Read – Heavy rain hits traffic, flightsThe Rajbari, a classic example of British architecture, is in shambles. A major portion of the roof has collapsed and the dancing floor on the first floor is in real bad shape. Bushes and trees have grown all over the house. A senior architect who visited the house a few years ago said the building has tilted towards the river. To repair the roof, a lot of money will be required.But the state Heritage Commission does not have money to repair and restore the huge structure. “The building has enormous historical value and should be preserved,” said a member of the state Heritage Commission.

Many foreigners, who are fans of Satyajit Ray come to see the building,” said Sudip Basu, a local resident.Satyajit Ray’s famous film Jalsaghar was shot in this building. Based on a story by Tarashankar Bandyopadhyay, the cast included Chabi Biswas, Padma Devi, Tulsi Lahiri, Gangapada Basu among others. The music was done by Ustad Vilayat Khan while two of India’s greatest vocalists — Ustad Waheed Khan and Begam Akhtar — lent their voices to two immortal songs in the film.
British engine maker Rolls-Royce will axe another 400 jobs at its marine division, it said on Monday, as slumping oil prices weighs on demand for vessels. Rolls announced in a statement that it will reduce its number of employees by 400 by the end of next year, on top of 600 job cuts already unveiled in May.”After many years of strong performance through to 2013, led by good growth in the oil and gas sector, our order book and profitability have been adversely impacted by the sharp and subsequently prolonged drop in the price of oil,” said Mikael Makinen, President of Marine at Rolls-Royce. “Reducing our workforce is never an easy decision, but the continued weak oil price, and the need to become more competitive, means it is necessary, if we are to build a strong base from which we can successfully grow this business in the future.” Also Read – Punjab & Sind Bank cuts MCLR by up to 20 basis pointsThe latest cutbacks are forecast to generate full-year savings of $61 million.

He then decided to name the place after the flower, and thus the name, Pushkar. The city of Pushkar is home to the only temple dedicated to Lord Brahma in the whole world. Hindus consider a journey to Pushkar to be the ultimate pilgrimage that must be undertaken to attain salvation.PUSHKAR LAKEAccording to Hindu scriptures, the sacred Pushkar Lake is described as ‘Tirtha Raj’, the king of all pilgrimage sites. No pilgrimage is considered to be complete without a dip in the holy Pushkar Lake. Semi-circular in shape and about 8-10 metres deep, Pushkar Lake is surrounded by 52 bathing ghats and over 400 temples and is truly a magnificent sight to behold. BRAHMA TEMPLENestled in the picturesque Pushkar valley beyond the Nangaparvat and Anasagar Lake, the Brahma temple holds a special place in the hearts of Indians. It is the only temple in the world dedicated to Lord Brahma. Built with marble and decorated with silver coins, this temple can be identified by its red spire and the image of a swan (considered sacred to Lord Brahma). The chaturmukhi (four faced) idol of Lord Brahma is housed in the inner sanctum. A marble statue of the sun god stands sentinel at the temple. Interestingly, while all the gods are shown bare footed, Surya is shown wearing ancient warrior’s boots.GURUDWARA SINGH SABHAGurudwara Singh Sabha, situated in the eastern part of Pushkar, was built in the beginning of the 19th century to commemorate the visits of the first and the tenth gurus- Guru Nanak Dev and Guru Govind Singhji.VARAHA TEMPLEVaraha temple is the largest and the most ancient temple of Pushkar. Constructed by the 12th century ruler, King Anaji Chauhan, this temple is dedicated to the third incarnation of Lord Vishnu as a wild boar. Legend has it that Varaha rescued the earth from depth of the primeval water, where it was dragged down by a demon (Hirnayaksh). It is one of the most visited temples in Pushkar.SAVITRI TEMPLEDedicated to Lord Brahma’s first wife, Goddess Savitri, this temple is situated on a hillock right behind the Brahma temple. While climbing the long series of steps leading to the temple, one can catch a panoramic view of the lake, surrounding temples and sand dunes. The presence of the only Brahma Temple in Pushkar is the outcome of Savitri’s curse to Brahma for marrying another Goddess, Gayatri, while starting his yagna in Pushkar.RANGJI TEMPLEThe gracious and conspicuous Rangji Temple is another popular shrine that witnesses thousands of pilgrims and tourists every year. The temple is dedicated to Lord Rangji, believed to be an incarnation of Lord Vishnu. The influence of South Indian style, Rajput style and Mughal style in the temple’s architecture is highly noticeable. The high-rising ‘Gopuram’, prevalent mainly in the temples present in South India is another feature of the temple that attracts visitors.PAP MOCHINI TEMPLEPresided by the deity Ekadashi Mata, the Pap Mochini temple is believed to provide respite to followers from their cardinal sins. Located in the northern section of Pushkar, the temple is like a pearl in the crown of Pushkar. Having a great spiritual importance as well as boasting a splendid architecture, the Pap Mochini temple is one of the most popular temples in Rajasthan.SRI PANCHKUND SHIVA TEMPLESri Panchkund Shiva Temple is said to have been built by the five Pandavas. Located on the eastern edge of the town, this temple is around 2-3 kilometres from the lake.ATMATESHWAR TEMPLEThis beautiful 12th century temple is dedicated to Lord Shiva and has an underground component. The intricate Hemadpanti architectural style carvings give this temple a magnificent appearance. Thousands of devotees flock here to pay their respects during the auspicious time of Shivaratri, when Lord Shiva is ritually respected.MAN MAHALThe Man Mahal is one of the greatest palaces of Pushkar. Built as a guest house of Raja Man Singh I, this palace is one of the most attractive spots to visit in Pushkar. It was built to serve as a royal guest house for Raja Man Singh I. The Rajasthani architecture from the royal era that adorns the palace makes it a visual treat. It has now been converted into a heritage hotel, called the RTDC Hotel Sarovar, and allows tourists to not only enjoy the beauty of the palace but also the breathtaking view of the lakes and temples around the lake.HOW TO REACH HERESanganer Airport in Jaipur is the nearest, at a distance of 146 kilometres.Pushkar is well connected to the national highways of Rajasthan. Regular buses ply from Pushkar to the major cities of Jaipur, Jodhpur and Ajmer from the Ajmer bus stand.Pushkar Terminus Railway station which is operational since 2012, is connected to Ajmer railway station located at a distance of 11 kilometres.
