Chelsea have confirmed that promising midfielder Nathan will return to Vitesse for another loan next season.Chelsea landed the 20-year-old from Atletico Paranaense last July and sent him straight out on loan to the Dutch club.He made 18 Eredivisie appearances, scoring twice, and showed glimpses of why he is rated as one of the best young talents from Brazil.And now he will get the chance to secure more senior first-team football in Holland after Chelsea agreed to send him to Vitesse for the whole of the coming season too. Can Nathan ever make it at Chelsea? 1
A thin section of the rib of the 195 million year old dinosaur Lufengosaurus, cut along the length of the rib showing a vascular canal with dark hematite particles. These were probably derived from the iron rich blood cells of the living dinosaur, and would have provided the internal environment for the preservation of collagen. Lacunae, where adult bone cells would reside, are also preserved with dark hematite particles inside them. Credit: Robert ReiszLacunae are channels in bone that carry blood vessels and nerves. What the caption calls lacunae appear in the photo to be intact osteocytes (bone cells), complete with delicate filopodia. The article claims original non-mineralized protein is present.They found evidence of collagen proteins within tiny canals in the rib and concluded they were “probably remnants of the blood vessels that supplied blood to the bone cells in the living dinosaur.“New techniques with synchrotron radiation-based nano-transmission X-ray microscopy (SR-TXM) used by the researchers primarily from Taiwan, with Robert Reisz from Canada, allowed intact imaging without damage. This no longer requires dissolving away the bone, like UNC researchers (Mary Schweitzer and team) had done earlier.Most previous studies had extracted organic remains by dissolving away other parts of the fossil, the team said.With the synchrotron method, this is not necessary, and even older remains may be uncovered without damaging dinosaur bones in future.The article repeats the common assumption that “finding fossilized soft tissue is very rare indeed.” But with the synchrotron method, perhaps scientists will begin seeing more of it, now that they know what to look for. The dinosaur is a Lufengosaurus, a type of long-necked sauropod first discovered in China. Here’s what the open-access paper in Nature Communications says:Various skeletal elements of the sauropodomorph dinosaur Lufengosaurus from the Lower Jurassic (Early Jurassic, Sinemurian, 190–197 Mya) of Dawa, Lufeng County, Yunnan Province, China, were studied in detail; however, surprisingly, it is the rib materials that produced the most significant results (Fig. 1a–m). Adult compact bone (including ribs) is composed of osteons with central vascular canals (Fig. 1b–h) that contain blood vessels and nerves in the living organism and lacunae, or spaces for the adult osteocytes (Fig. 1m).[After describing the imaging techniques, they report:] The results indicate that native collagen was preserved within the osteonal central vascular canals, together with haematite particles that were likely derived, at least in part, from haemoglobin of the dinosaur.Schweitzer’s team had also reported original collagen, but their dinosaur was dated at less than half the age: 80 million years instead of 195 million years. If Schweitzer’s date for preservation was incredible, how much more this far “older” specimen? (Click here for list of articles on Schweitzer’s soft-tissue research.)Update 1/31/17: Not many science sites have reported this stunning find yet, but the BBC News did. Reporter Helen Briggs offered some responses to this “‘startling’ dinosaur protein discovery.” Paleontologist Robert Reisz confirms that they found original material: “We are actually looking at the preservation of the original materials that were in the living organism rather than an impression of the soft tissues that were there.” Scottish dinosaur-hunter Stephen Brusatte was shocked:Stephen Brusatte of the University of Edinburgh, who is not connected with the research, said the discovery was “a jaw-dropper“.“To find proteins in a 195-million-year-old dinosaur fossil is a startling discovery,” he told BBC News.“It almost sounds too good to be true, but this team has used every method at their disposal to verify their discovery, and it seems to hold up.”He did not call into question the date, however, preferring to remain a moyboy and change his assumptions about how long soft material might survive.The paper in Nature Communications suggests the following explanation: “We propose that haematite cementation may have played an important role in the preservation of these organic remains, isolated within the vascular canals by haemoglobin-derived haematite aggregations.” This was the explanation first suggested by the Schweitzer team. Mark Armitage, though, who has done independent studies of intact soft tissue in dinosaur bone, does not accept the idea that iron from hemoglobin can preserve the delicate details he has seen with his electron microscope.Update 2/02/17: The press release from Reisz’s institution, the University of Toronto, includes a photo of the skeleton as found in the ground in China, and also another micrograph of the soft tissue.Think about this: if scientists were already astonished at preservation for 80 million Darwin years, how much more for 195 million? Did the 115-million-year difference even exist? Wouldn’t it be far more credible to think all these dinosaurs lived and perished around the same time?We can’t let the DOPE peddlers get away with revisionism. They’re going to try three main talking points: (1) Protein actually can survive hundreds of millions of years, and these bones prove it, because they are 195 million years old (proof by assertion). (2) Iron from blood preserves original protein. (3) Now that we have dinosaur protein, we can learn more about evolution; isn’t that wonderful?This is what they are already saying. It’s time to turn up the heat on these fake-science peddlers. We know that they were shocked with utter disbelief that any original tissue could last even one million years, let alone 80 or 195 million. It’s not possible. It’s time to wage war on the moyboy myth, armed with this powerful empirical evidence. Who has the science on their side now?

By now, most conscientious builders know that window rough openings need to be carefully flashed before a window is installed. For residential builders, the most common way, by far, to flash window rough openings is with peel-and-stick flashing.However, an increasing number of builders are taking a closer look at something different: liquid-applied flashing.Liquid-applied flashing comes in various forms. Some products are dispensed from cartridges like caulk; others come in a pail and have the consistency of mayonnaise.If you are using liquid-applied flashing to flash a window rough opening, you squeeze or spread a generous amount on the surfaces that need flashing — generally the rough sill, the rough jambs, the head, and a 6 to 8 inch wide band of the wall sheathing around the perimeter of the rough opening — and then you spread the material out with a trowel or a plastic Bondo spreading tool. (Some products have a thinner consistency that can be applied with a brush or roller.) Most manufacturers advise adding enough material to make an opaque layer — one that you can’t see through.In addition to being useful for flashing window rough openings, liquid-applied flashings can be used to flash penetrations through wall sheathing — for example, vent pipes or plumbing pipes.Liquid-applied flashings are stick tenaciously to a wide variety of materials. Most manufacturers of liquid-applied flashing claim that their products stick to plywood, OSB, framing lumber, concrete, CMUs, brick, aluminum, painted steel, vinyl, rigid foam, glass, and EPDM. (Note, however, that some manufacturers warn that their products don’t stick to housewrap.)Most brands of liquid-applied flashing can bridge cracks up to 1/4 inch wide without the need for any caulk or reinforcing mesh. Once cured, these flashings form a rubbery layer that is vapor-permeable yet waterproof and airtight.This installation method is fairly… This article is only available to GBA Prime Members Start Free Trial Already a member?

Return to article. Long DescriptionHave you ever experienced a morning that leaves you frazzled and stretched-thin? Perhaps the alarm failed to ring on time, or a family member required a little extra care. Perhaps you failed to leave enough time for a heavy morning commute, or you found yourself unable to take a few minutes to eat breakfast or grab a drink before making a mad dash. Did you arrive at your destination feeling unsettled or disorganized?While no amount of planning can eliminate all morning challenges, for some, an overly-stressed morning routine is the rule, rather than the exception. Consistently hectic mornings that leave you physically and mentally depleted can negatively impact your health and mood, making it more difficult to achieve full productivity. Investing a few minutes each morning in activities that nourish your body, mind and spirit may provide benefits that last throughout the day and beyond.How important is morning wellbeing?According to research published in the Academy of Management Journal, employee mood at the start of the workday impacts how employees perceive work events and how they ultimately perform at work. The study found that employees arriving at work in a negative start-of-workday mood tended to perceive work events more negatively, experience more negative feelings about work, and demonstrate lower quality work performance. (Rothbard and Wilk 2011).While cognitive benefits associated with nourishing the body have been well documented, some have identified a number of performance-related benefits associated with taking time in the morning to eat a healthy breakfast. According to the Mayo Clinic:Adults who report regularly eating a healthy breakfast:Eat more vitamins and minerals.Control their weight. Research suggests that consuming most of your daily calories in the morning can aid weight loss.Control their blood sugar levels — which is important in preventing or controlling diabetes.Eat less fat and cholesterol.Perform better at work. Invest in a morning routine that enhances wellbeing. Planning time in the morning for self-care may represent one of the very best investments that you can make. Below are three strategies to help boost your morning routine in ten minutes or less.(1). Eat breakfastFor many busy adults, finding the time to prepare and eat breakfast can be daunting. The 5, on the Go Hearty, Heart Healthy Breakfast Ideas publication from the Cleveland Clinic provides excellent strategies for quick and nutritious breakfasts, with items that require no more than 10 minutes to prepare.(2). HydrateHydration is an extremely important component of overall health that can become overlooked when time is tight. Taking time to properly hydrate is one of the best things you can do for your body in the morning, and throughout the day. For easy hydration strategies, check out this Secrets of Self-Care Hydration Resource.(3). Boost your mood Let’s face it, sometimes we all just wake up on the wrong side of the bed! This nine-minute loving kindness meditation from the University of California can help establish a positive mood in the morning or any time.Do you have effective go-to morning strategies to share?

Pune: The kin of Rasila Raju O.P, the Infosys software engineer who was murdered last month, submitted a memorandum to Pune Commissioner of Police Rashmi Shukla on Thursday, urging a thorough probe in the murder.Ms. Raju (24) was found strangled to death inside the premises of the Infosys campus in the city’s Hinjewadi IT Park on January 29. A security guard of the campus, Bhaben Saikiya (26), has been arrested in connection with the case.Speaking to The Hindu, Rasila’s father Raju O.P. said the family has submitted a six-point memo to Ms. Shukla, in which they have urged the police to probe whether the murder was committed by more than one person.Evidence submitted Rajan Nair, of the Pune Malayalee Federation, said, “We have also submitted evidence that Rasila was under pressure three months before her death and have urged the police to probe accordingly. We have further requested that IT firms carry out thorough background checks of security personnel.”According to Mr. Nair, the Commissioner assured the kin that every evidence was being looked into and that ordinary ‘work pressure’ had to be distinguished from sinister circumstances, which may have contributed to the murder.Mr. Nair added, “We also seek the appointment of noted lawyer Ujjwal Nikam as Public Prosecutor in the case and demand capital punishment for the accused.” Earlier, the kin had submitted a Memorandum of Agreement to the human resource authorities at Infosys for seeking the dues and ex-gratia payment amounting to ₹1.25 crore. The kin said the authorities have responded positively.Ms. Raju, who hailed from Payimbra village in Kozhikode city, Kerala, had been working with Infosys since 2015.The prime suspect, Saikiya, a native of Assam, is in judicial custody till February 21. He purportedly used to stare at the victim in an improper manner, which caused her to warn him of a complaint. According to police, this is supposed to have triggered the crime.Saikiya, who fled after the murder, was nabbed from Mumbai’s Chhatrapati Shivaji Terminus (CST) by the Pune police in the wee hours of January 30. He was attempting to escape to his native village in Assam.Soon after the event, Ms. Shukla questioned the security measures at the Infosys campus.
Enter the CIADhondup was a member of the only modern insurgent group of Tibet, the Dhokham Chushi Gangdruk (DCG). The DCG was formed on June 16, 1958 in Tibet by a charismatic nobleman, Andrup Gonpo Tashi. For some time the group carried out ambushes against the Chinese forces as Beijing tried to consolidate its gains in Tibet. Dhondup, then in his twenties, was one of the early recruits in this movement and was trained in sabotage and the use of arms.“During the struggle, we used basic weapons like the old rifles that fired one bullet at a time,” he says, explaining that the movement expanded rapidly from the Kham region of Tibet despite shortage of weapons and ammunition.The DCG became known worldwide for being the secret force of the CIA, which sent trainers and equipment to Tibet to support the rebels. Dhondup recalls how the Americans sent high-flying cargo jets into the Tibetan airspace for his group that consisted of 600 volunteers. The war of 1971 was not the first Dhondup and his compatriots in Lama Camp experienced. Their war began 20 years earlier in the 1950s, when they fought a guerrilla battle against the Chinese forces in Tibet supported by weapons and trainers from the U.S. Central Intelligence Agency (CIA) which wanted to dislodge China from Tibet.As we catch up with Dhondup, he is soaking in the celebrations of Losar, the Tibetan New Year which began in the last week of February. Losar to the Tibetans means crushed corn which is sprinkled on guests and meant for auspicious occasions, good food, drinks and a time to recollect the past. His kitchen is stocked with savouries and drinks. This is the Year of the Firebird which, like the phoenix, stands for resurrection and the burning away of wasteful deeds. Keeping with the spirit of the new year, Dhondup wants to relive the war of his youth.“We had inadequate weapons and ammunition but we wanted to fight the Chinese who forced us to build roads and bridges,” he says in a mix of Hindi and Tibetan that was interpreted by his son Tsering. The guerrillas fought with .303 rifles of World War II vintage, receiving better weapons only in the later phase.Dhondup and five other veterans are the remaining few from the hundreds of unknown foot soldiers of a liberation war, unlamented and unsung. These former soldiers were of fighting age; in exile now, time is ticking away. Many have passed away. One of their comrades, who rose to run a movie theatre in the neighbourhood, passed away earlier this year. They were the pioneers of a resistance movement that took to violence before the Dalai Lama weaned them away to non-violent means.

Dhondup Palden and his wife Sonam at their residence in Lama Camp. One of the key assignments of the DCG was to guard the Dalai Lama as he planned to go into India. A little distance away from Dhondup’s Tezu home lives one of the former DCG fighters who accompanied the Dalai Lama during that momentous journey. “The journey of 1959 was arduous. Yaks and horses were used to cross the snowy mountain. We ensured safety for the Dalai Lama with one group travelling with him and another providing support at Lhasa,” says Zolpa Sibu, the ex-DCG fighter.Sibu is nostalgic about his DCG days. “We did not have the best of weapons to fight. Many of our comrades died in bombing and counter-insurgency operations carried out by the Chinese forces,” he says, recounting that even the force’s founder was brought to India with injuries he sustained in a blast. He remembers how grim the situation in Tibet had become. “We were evicted from our homes. Families broke up — the Chinese employed women and men separately for forced labour projects that would go on for months. Social and religious gatherings became impossible as the police questioned all such gatherings.”The DCG put up a strong resistance, but the end was inevitable. Sibu was arrested but released after months of detention. As was Dhondup. “I was kept in prison for two months and for weeks my hands were tied up,” he says, showing his permanently scarred hands.The DCG’s fighters decided to escape into India through the mountain passes in eastern Arunachal district of Upper Dibang Valley and the western district of Tawang via Bomdila. The journey was difficult; many perished but the likes of Dhondup, Sibu and their families survived the trek.The war for BangladeshSoon after coming into India, these fighters were asked to settle in Tezu but within a year they had to move as India-China hostilities intensified in the run-up to the 1962 war. As the border districts of the North East Frontier Agency, as Arunachal Pradesh was then known, were evacuated, the fighters were resettled in Dibrugarh and Guwahati in Assam. They returned to Tezu after the war ended, and soon found themselves recruited by Indian military officers who had by now realised their potential as trained guerrillas and intelligence-gatherers. “The military instructors tested our firing skills, asked us to take physical fitness tests. Most of us passed the test and joined the Indian military as we were eager to go back to Tibet and fight the Chinese forces again,” says Dhondup.The fighters boarded a train at Guwahati and were taken to Chakrata in Uttarakhand (then in Uttar Pradesh) where a rigorous training programme began to equip them for special military operations. “We were trained to handle mortar fire, automatic weapons, rocket launchers. I was specially recruited into a team of paratroopers in the SFF,” says Dhondup, explaining that the Tibetans were expected to go back into their country for special operations. As first-generation exiles, the men did not always understand the detailed discussions held among Indian military officers, but carried out the assigned duties nevertheless.Havildar Sangey was also among the ex-DCG SFF recruits. He counts himself as lucky, having been taken as part of a three-member group for a special training programme in Europe. “I even trained with some American officials abroad,” he says, reliving his days as a paratrooper.The hostility between India and Pakistan gave the SFF fighters a new chance to test their fighting skills. “During the 1971 war, many of our friends died fighting,” says Dhondup, recounting that the war had left him injured and he was admitted in the Armed Forces Medical College, Pune. “Generals and [Prime Minister] Indira Gandhi came to see us in hospital. We got a transistor radio as reward,” he adds, his eyes lighting up as he recounts the heady days.By the time the Bangladesh war ended, most of the soldiers had acquired family and had young kids at home. But newer assignments beckoned, including reconnaissance missions in Ladakh and in the high Himalayas. “We wanted to fight in Tibet because the SFF [training] taught us lot more than we knew in the DCG days, but that fight never came,” rues Sangey. “We had all the necessary advanced weapons. We would not have left Tibet if we had these weapons and training at that time.”Renewed rumble in the east The amphitheatre of much of the 1962 war, the epic face-offs of yesteryear still linger in the air of the Arunachal Himalayas, especially the mountains from Tezu to Anjaw district which were the scene of the bloodbath of Namti where an unknown number of Indian and Chinese soldiers died.Having spent their youth in the midst of guerrilla warfare and tectonic political churn, the elderly denizens of Lama Camp find themselves still engulfed by geopolitics thanks to the evolving importance of the Eastern Himalayas. In recent years, the U.S. and India have begun to work on salvaging the remains of aviators who crashed in the mountains near Tezu during World War II. The discovery of a Chinese citizen in the region in 2010 stirred up matters between India and China. Guang Liang spent months in a prison in Arunachal Pradesh before the Chinese reportedly took him back. In addition, barely a dozen kilometres from the neighbourhood of these former guerrillas is the brand-new easternmost airport of India at Tezu which can also host heavy bombers and cargo carriers. Recent reports about an impending visit by the Dalai Lama to Arunachal Pradesh have again stirred up the pioneers of DCG.While the region remains the locus of power games, the exploits of the octogenarians of Lama Camp slowly recedes into oblivion. In the sunset of their lives, they wish to bequeath their saga of resistance in Tibet to posterity. “Most of us did not get a chance to lead a normal life. We were deprived of the education that would have trained us to record and write our experience as soldiers,” says Sibu.The legacy and the futureIn recent years there have been some attempts to recognise their signal contribution. The Central Tibetan Administration has set up offices in Delhi and Dharamsala for addressing the needs of these senior community members. On the 50th anniversary of the founding of DCG in 2008, special commemorative events were organised by the Tibetan community in India to honour them and recognise the armed struggle that they executed against China.Young Tibetans also drop in once in a while to seek blessing of these elders. The Tibetan diaspora has also shown interest in chronicling the story of DCG and a number of websites provide information about the violent movement which faded out with the exile of Tibetans to India. However most of the literature focusses on the CIA’s role in fuelling the war in the Cold War period and is inadequate in recording the narratives of the men who fought the war not just for the CIA but also for India. “Our lives were disrupted. At the time of DCG, we did not foresee our exile and that is why we did not bother to photograph our homes and our struggles,” says Sibu, urging better documentation of the scattered photographs and other records of the movement in Tibet.Despite their advancing years, the DCG fighters do not receive any additional financial support from the Government of India — the SFF gave a comprehensive settlement package, a one-time lump-sum amount at the time of retirement.While the passage of time has dimmed Dhondup, Sibu and Sangay’s hopes of returning to their homeland, the fire still burns. “Even now I dream of fighting in the streets of Tibet with a gun,” says Dhondup. The DCG, incidentally, still exists in exile, espousing an independent Tibet. Dreams don’t die. On December 16, 1971, the India-Pakistan war ended with the liberation of Bangladesh. The war was short — it had raged for all of 13 days — but India had mobilised its entire land forces, including a secretive unit of soldiers from the Special Frontier Force (SFF), a group raised for trans-Himalayan combat. Some of the SFF recruits were not Indians. They were from Tibet and had come into India on forced exile, in waves and participated in the ground battles and the combing operations that followed with minimal knowledge of South Asian languages and the people they encountered. They had hoped that after the war India would send them home to fight the Chinese forces in Tibet as a reward — but that was not to be.Dhondup Palden, now in his 80s, a resident of Lama Camp in Tezu, Arunachal Pradesh, was one of the Tibetans who despite their Buddhist faith took up arms. Sitting at the porch of his home-on-stilts that is painted blue and decorated with Buddhist prayer flags, he reminisces about the war and how he had ventured into unfamiliar territory. “We killed many enemies in that war. For 15 days, we moved across the country rounding up Pakistani soldiers and pro-Pakistan agents.” The war stood out as it was the first time that the Tibetans, a mountain people, had to negotiate with the riverine landscape of Bangladesh. “We walked on muddy riverbeds, and went from village to village looking for enemies. The experience was unusual for us Tibetan soldiers,” he says. Zolpa Sibu Lama (left) and Adrouk with their certificates | Photo Credit: Ritu Raj Konwar
Tripura Assembly Speaker Ramendra Chandra Debnath, on Friday announced the disqualification of Ratan Lal Nath,MLA, under the anti-defection law. The former leader of opposition who won from Mohanpur assembly constituency five times in a row as a Congress nominee, had recently joined BJP. The state Congress President Birajit Sinha had lodged a complaint with the Speaker to disqualify Mr. Nath a day after the latter joined BJP on December 22 last. Hundreds of his supports also joined the party at a function attended by BJP General Secretary and party’s northeast in-charge Ram Madhav and Tripura poll in-charge as well as Assam Finance Minister Himanta Biswa Sarma.Following the Congress complaint, the Speaker had called him for an explanation but Mr. Ratan Lal had skipped the hearing convened by the Speaker citing health reason.
Three of the 22 students who died in the fire on Friday had appeared for the Class XII Board exams and cleared them comfortably, as per the results that were declared on Saturday.The students were identified as Yashvi Kevadiya, Mansi Varsani and Hasti Surani. “While Yashvi passed the exam with 67.75 percentile (C1 grade), Mansi received 52.03 percentile (C1 grade) and Hasti scored 69.39 percentile (B2 grade),” said Surat police spokesperson P.L. Chaudhari.
Shikhar Dhawan’s participation in the first Test against South Africa starting on January 5 looks to be doubtful.The Southpaw was seen limping while entering the Team India hotel in Mumbai.Dhawan has picked up an ankle injury and was seen with a heavily strapped left-ankle on Wednesday.He was accompanied by physio Patrick Farhart and has undergone for an MRI scan.”Shikhar Dhawans ankle is being assessed. The physio is yet to give any report to the national selectors. As of now, he is travelling with the team. However, it cant be ascertained whether he will be available for the first Test match or not,” a senior BCCI official told PTI on the condition of anonymity.Dhawan has been in good form after making his comeback to Test cricket in Sri Lanka and has hit 550 runs from eight innings, including two hundreds. He was expected to play the first Test alongside Murali Vijay. However, if he is rendered unfit for the first Test, then in-form KL Rahul is expected to open the batting with Vijay.As per the selection pattern of the Indian teams whenever there has been an injury concern, the fourth opener currently would be Tamil Nadu’s Abhinav Mukund, who had scored 82 in his last Test appearance in Sri Lanka.India will fly for South Africa soon and will play three Tests, six ODIs and three T20Is.(With inputs from PTI)
