Why some electrons quickly kick into high gear has been debated for more than a decade, with two theories considered the most viable. Now, physicists from Los Alamos National Laboratory (LANL) have verified one of these theories using data collected from several satellites. The research, published in the September issue of Nature Physics, may lead to better space-weather models, which may help scientists predict when ultrahigh-energy electrons are abundant and, therefore, most dangerous.“These ‘killer’ electrons can harm astronauts and even passengers on regular airline flights that go through Earth’s polar regions,” the paper’s lead author, LANL physicist Yue Chen, said to PhysOrg.com. “Therefore, people need to know the source of the these electrons so as to develop the ability to predict when they’ll be most numerous. Our paper finally settles the argument.”The group’s work may also eventually help improve the design and operation of satellites, which are very susceptible to radiation effects and very expensive to repair or replace when damaged. Killer electrons can penetrate satellite radiation shields and cause malfunctions in the electronics on board.The LANL group shows that the electrons’ acceleration is mainly due to “gyro-resonant wave acceleration,” the end result of a complex domino effect that begins when particles from the solar wind and Earth’s ionosphere (the layer of the atmosphere that is about 50-400 kilometers above the surface and contains molecules that are ionized by solar radiation) are sporadically injected into the radiation belt. This influx, bearing an unstable distribution of particles, excites many electromagnetic waves. The relative motion of waves and particles along the belt’s magnetic field lines induces a Doppler shift of the wave frequency. Next, a resonant interaction occurs between the Doppler-shifted waves and electrons in the belt that are gyrating (moving in a circle around the field lines) at the same frequency as the waves – an effect known as gyro-resonance.Most of the electrons injected into the belt follow trajectories that are nearly parallel with the magnetic field lines, and they soon lose energy. But for electrons that were initially injected at angles more perpendicular to the field lines – those with larger “pitch angles” – gyro-resonance has the opposite effect: a serious energy boost.The losing theory, which was the accepted explanation until satellite data cast it into doubt in the mid 1990s, is “radial diffusion.” It states that fluctuations in the magnetosphere’s electric and magnetic fields send electrons diffusing down into the belt from Earth’s plasma sheet, a region of relatively low-energy energetic particles that extends behind Earth, away from the Sun. As the electrons descend into the stronger magnetic fields closer to Earth, they accelerate.Chen and his colleagues used several instruments to collect the electron data that ultimately led them to verify that the gyro-resonant wave-particle interaction is the dominant acceleration mechanism. These included the Los Alamos energetic particle sensor, which sits on-board a global positioning system (GPS) satellite; the lab’s GEO Synchronous Orbit Particle Analysis instruments, and a set of instruments mounted on NASA’s Polar satellite, collectively known as the Comprehensive Energetic Particle and Pitch Angle Distribution experiment.Citation: Chen, Y., Reeves, G.

Electrons trapped in the outer Van Allen radiation belt, a doughnut-shaped region of high-energy particles that surrounds Earth, kept in place by our planet’s magnetic field, can have velocities approaching the speed of light. But the number of these “killer” electrons varies wildly: a few one day, many more the next. The cause has puzzled scientists – until now.

The effect can be explained because (1) the speed of light is a constant (independent of how fast a light source is moving toward or away from an observer) and (2) the universe is expanding at an accelerating rate, which causes light from distant objects to redshift (i.e. the wavelengths to become longer) in relation to how far away the objects are from observers on Earth. In other words, as space expands, the interval between light pulses also lengthens. Since expansion occurs throughout the universe, it seems that time dilation should be a property of the universe that holds true everywhere, regardless of the specific object or event being observed. However, a new study has found that this doesn’t seem to be the case – quasars, it seems, give off light pulses at the same rate no matter their distance from the Earth, without a hint of time dilation.Astronomer Mike Hawkins from the Royal Observatory in Edinburgh came to this conclusion after looking at nearly 900 quasars over periods of up to 28 years. When comparing the light patterns of quasars located about 6 billion light years from us and those located 10 billion light years away, he was surprised to find that the light signatures of the two samples were exactly the same. If these quasars were like the previously observed supernovae, an observer would expect to see longer, “stretched” timescales for the distant, “stretched” high-redshift quasars. But even though the distant quasars were more strongly redshifted than the closer quasars, there was no difference in the time it took the light to reach Earth.This quasar conundrum doesn’t seem to have an obvious explanation, although Hawkins has a few ideas. For some background, quasars are extreme objects in many ways: they are the most luminous and energetic objects known in the universe, and also one of the most distant (and thus, oldest) known objects. Officially called “quasi-stellar radio sources,” quasars are dense regions surrounding the central supermassive black holes in the centers of massive galaxies. They feed off an accretion disc that surrounds each black hole, which powers the quasars’ extreme luminosity and makes them visible to Earth.One of Hawkins’ possible explanations for quasars’ lack of time dilation is that light from the quasars is being bent by black holes scattered throughout the universe. These black holes, which may have formed shortly after the big bang, would have a gravitational distortion that affects the time dilation of distant quasars. However, this idea of “gravitational microlensing” is a controversial suggestion, as it requires that there be enough black holes to account for all of the universe’s dark matter. As Hawkins explains, most physicists predict that dark matter consists of undiscovered subatomic particles rather than primordial black holes.There’s also a possibility that the explanation could be even more far-reaching, such as that the universe is not expanding and that the big bang theory is wrong. Or, quasars may not be located at the distances indicated by their redshifts, although this suggestion has previously been discredited. Although these explanations are controversial, Hawkins plans to continue investigating the quasar mystery, and maybe solve a few other problems along the way.Hawkins’ paper will be published in an upcoming issue of the Monthly Notices of the Royal Astronomical Society. (PhysOrg.com) — The phenomenon of time dilation is a strange yet experimentally confirmed effect of relativity theory. One of its implications is that events occurring in distant parts of the universe should appear to occur more slowly than events located closer to us. For example, when observing supernovae, scientists have found that distant explosions seem to fade more slowly than the quickly-fading nearby supernovae. © 2010 PhysOrg.com This X-ray image shows the quasar PKS 1127-145, a highly luminous source of X-rays and visible light located about 10 billion light years from Earth.

We may all be Martians: New research supports theory that life started on Mars (Phys.org) —A trio of researchers at the University of Nevada has found that phosphate found in minerals on Mars, is far more soluble than it is in natural Earth minerals. In their paper published in the journal Nature Geoscience, the researchers describe how they synthesized mineral types found on Mars and then tested how well they dissolved in water releasing phosphate as compared to samples from natural Earth minerals. © 2013 Phys.org Journal information: Nature Geoscience More information: Readily available phosphate from minerals in early aqueous environments on Mars, Nature Geoscience (2013) DOI: 10.1038/ngeo1923AbstractIf the chemistry essential to life was present in water-containing environments on Mars, the processes that led to life on Earth may have also occurred on the red planet1. Phosphate is one of the chemical nutrients thought to be essential for life and is also considered critical to reactions that may have led to life on Earth2, 3. However, low prebiotic availability of phosphate may have been a complicating factor in terrestrial abiogenesis2, 4, suggesting that a similar hurdle may have confronted the development of life on Mars. Phosphate available for biological reactions can be introduced into aqueous environments through dissolution of primary phosphate minerals during water–rock interactions, but little is known about the dissolution of the dominant phosphate minerals found in martian meteorites and presumably on Mars5, 6, 7, 8. Here we present dissolution rates, phosphate release rates and solubilities of phosphate minerals found in martian rocks as determined from laboratory measurements. Our experimental findings predict phosphate release rates during water–rock interactions on Mars that are as much as 45 times higher than on Earth and phosphate concentrations of early wet martian environments more than twice those of Earth. We suggest that available phosphate may have mitigated one of the hurdles to abiogenesis on Mars.

If life ever arose on Mars, merrillite may have been a major source of biologically required phosphate. Largest crystal are ~1mm. Credit: C. T. Adcock / University of Nevada Las Vegas Most scientists agree that phosphate is a key ingredient for life. Put another way, they believe that life couldn’t have evolved without it. For that reason, scientists have been studying ways in which minerals that contain phosphate could have broken down to allow the phosphate to escape. Such studies have thus far found that minerals that hold phosphate on Earth are not very soluble—they don’t break down easily when soaked in sea water. That has led to what Earth scientists call “the phosphate problem.” How did life get started on Earth if there wasn’t enough phosphate around when life was first beginning? Some have suggested the answer is that it didn’t, instead, it started on another planet, such as Mars, and made its way here via meteorites. Prior research has already shown that Mars has much more phosphate than does Earth. In this new effort, the team in Nevada looked at minerals that exist on Mars to see if they might be more soluble in water as well.Lacking samples from Mars to test, the researchers synthesized chlorapatite and merrillite in their lab—two common phosphate bearing minerals found on the Red Planet. They then soaked samples in several tubs, each with a different pH level for varying amounts of time. As they did so, they measured how much phosphate made its way into the water and how long it took. In analyzing their results, the researchers found that more phosphate made its way into the water with both types of minerals and they did so at a faster rate than minerals that contain phosphate found naturally on Earth. In some cases, they report that the Mars rocks released phosphate up to 45 percent faster than Earth rocks.The findings by the team don’t prove that life began on Mars and migrated to Earth—after all, scientists have yet to prove life ever existed Mars. But it does add some credence to the argument that perhaps life did start somewhere other than our home planet, which if true, might mean it’s still out there waiting for us to discover it.

Amid Backdrop Of Hong Kong Protests, China Conducts ‘… Yuan Junmin by NPR News Scott Neuman 8.29.19 2:47am An annual rotation of Chinese troops in Hong Kong normally seen as a routine maneuver is taking on a more ominous tone this year amid warnings from Beijing of a possible crackdown on pro-democracy protests.Although the movement of People’s Liberation Army troops and vehicles in and out of Hong Kong is an annual exercise, China’s Xinhua news agency took the unusual step on Thursday of reporting the predawn deployment in real time instead of waiting until it was complete, as in previous years.The news agency published photos of armored personnel carriers passing through Huanggang Port, a land border crossing that separates Hong Kong from the city of Shenzhen in mainland China.In reporting the 22nd annual maneuver, which it described as “a normal routine annual rotation,” the news agency said PLA troops “have grasped the ability to defend Hong Kong.””[The troops] are determined to resolutely protect national sovereignty, security and development interests. They will effectively carry out the duty of defending Hong Kong, and perform more new contributions to maintaining the prosperity and stability of Hong Kong,” Xinhua said, echoing comments made earlier this month by Chen Daoxiang, the commander of the PLA garrison in Hong Kong.The troop rotation also serves as a show of strength after more than 11 weeks of sometimes violent protests that have rocked Hong Kong and severely challenged Beijing’s ability to administer the former British colony.Although Xinhua did not say how many troops were involved, the Hong Kong garrison is believed to number between 6,000 and 10,000. They are divided between bases in mainland China and former British army barracks in Hong Kong.In recent weeks, Chinese state media have shown video of troops of the PLA and the Chinese People’s Armed Police conducting anti-riot drills.While part of China, Hong Kong is a semi-autonomous region governed by a Beijing-appointed chief executive and a legislature weighted in Beijing’s favor.In early June, demonstrations began peacefully with the aim of opposing a proposed law to allow some in Hong Kong accused of crimes to be sent to mainland China for trial.However, demands of demonstrators have grown and the protests themselves have become more violent, prompting officials in Beijing to issue stark warnings of a possible crackdown. Earlier this month, a spokesman for China’s Hong Kong affairs office warned protesters not to “take restraint for weakness” and admonished that “those who play with fire will perish by it.”Hong Kong chief executive Carrie Lam, who has cautioned that the city could be pushed “into the abyss,” has not ruled out the possibility of invoking emergency powers to quell the unrest.Copyright 2019 NPR.

Bhel’s Heavy Electrical Equipment Plant (HEEP) at Haridwar, one the technology giant’s major manufacturing units, has become the first company in India to indigenously manufacture supercritical thermal sets of up to 800 mw rating. During financial year 2014-15, HEEP successfully manufactured India’s first 800 mw turbo generator and first 800 mw supercritical HP Turbine module for the Yeramarus power project in Karnataka; and the first 700 mw nuclear turbo generator for the Kalpakkam Atomic power plant. The 660-mw super critical thermal set manufactured at HEEP for the Barh power project in Bihar was also successfully synchronised with the grid and achieved full load. Despite last fiscal’s difficult business environment, HEEP achieved a turnover of Rs 3,541 crore and a profit before tax (PBT) of Rs 385 crore. With respect to physical performance, it manufactured 41 turbine modules totaling 5,113 MW, nine turbo generators of different ratings worth 5,865 mw and six condensers during fiscal 2014-15. In spite of stiff global competition and tough conditions in the power sector, HEEP has orders worth Rs 12,361 crore in hand for execution. As part of its technology upgradation programme, HEEP has achieved full capability to manufacture all types of modules of supercritical turbines of rating 660 mw and above. Also, for transporting 660 mw turbo generators through railways, HEEP has designed a new rail wagon jointly with RDSO-Lucknow, which will be manufactured by Bhel-Jhansi. The turbo generator for the Prayagraj Bara project has been dispatched using this wagon.During the year 2014-15, the Bhel unit at Haridwar spent a record Rs 89 crore for research & development (R&D) on new products and processes. HEEP developed and manufactured, for the first time, hydrogen coolers for 800 mw and 660 mw thermal sets for the Yeramarus and Mauda power projects respectively.
Kolkata: In a major move, the state Transport department has directed the district administration to remove the permanent ladders from private buses as part of the Safe Drive Save Life programme.The District Magistrates and Superintendents of Police have been asked to conduct special drives to remove the ladders. Temporary wooden ladders will be used to keep luggage on the roofs.The step has been taken as many buses that ply in the districts carry passengers on the rooftops which are solely meant for luggage. Also Read – Rain batters Kolkata, cripples normal lifeFlouting the norms, many buses that ply in the districts install permanent iron ladders after the registration of the buses are done and allow passengers to travel on the rooftops.The passengers sit on the rooftops and this is a common practice in districts including East and West Midnapore, Bankura and Murshidabad. In Howrah and Hooghly districts, the jeeps that ferry passengers in the rural areas carry commuters on the rooftops.Senior Transport department officials said it is risky to carry passengers in that manner particularly during the monsoon season when the roads are slippery. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedThe Transport department has also instructed the district administration to check tyres of the buses to avoid accidents.The decision has created a mixed response in the districts.While the majority of the commuters have welcomed the move, they maintained that the number of buses connecting rural areas with the city should be increased.The bus owners said as there is practically no space inside the buses to keep luggage, permanent ladders had to be installed.They admitted that commuters travel on the rooftops as the number of buses is not enough in number.
Exercises that improve coordination of muscles that support and control the spine offer a strategy to reduce pain and disability caused by lower back pain, finds a new study.Lower-back pain is one of the most common health conditions worldwide. It can have substantial health and economic costs as people experience disability and general ill health, leading them to need time off work.“Targeting the strength and coordination of muscles that support the spine through motor control exercise offers an alternative approach to treating lower back pain,” said lead author Bruno Saragiotto from The University of Sydney, Australia.Motor control exercise is a popular form of exercise that aims to improve coordination of the muscles that control and support the spine. Also Read – ‘Playing Jojo was emotionally exhausting’Patients are initially guided by a therapist to practise normal use of the muscles with simple tasks. As the patient’s skill increases the exercises become more complex and include the functional tasks that the person needs to perform during work and leisure activities. The study gathered together data from 29 randomised trials involving a total of 2,431 men and women, aged between 22 and 55 years old. The trials investigated the impact of using motor control exercises as a treatment for lower back pain compared with other forms of exercise or doing nothing.The researchers found that people who used motor control exercises experienced improvements, especially in pain and disability compared with minimal intervention.
Kolkata: Two trains came to a halt within a gap of almost 100 meters head on. This incident happened on Wednesday night around 10:30 pm near Patipukur.Sources informed that Down Haldibari Superfast Express halted at Patipukur due to a red signal since 9:30 pm. Meanwhile, the Up Jasidih passenger left Kolkata station around 10:25 pm. Sources informed that as some problems related to the signaling system had occurred on Wednesday night. The Jasidih passenger was supposed to avail the third track. But as per the signal, it started moving on the track used for circular rail movement. While advancing towards Dum Dum Junction, the pilot of Down Haldibari Superfast Express noticed a train is coming towards him on the same track. He immediately signaled the pilot of Up Jasidih passenger. Upon receiving the signal, the pilot of Jasidih passenger immediately applied emergency brake and succeeded in stopping the train within a short span as the speed was not high enough. Immediately, railway officials were informed. Almost 35 minutes later the problem got solved. The Jasidih passenger moved backwards and then changed the track. Due to this, the station master of Kolkata station has been suspended. An internal enquiry has been ordered.

Women should avoid eating too much vegetable oil and potato chips during pregnancy as such a diet may result in an increased risk of pregnancy complications and poor development of the babies, warns a study. Foods such as potato chips and vegetable oil contain omega 6 fats, particularly linoleic acid, and the research suggests that overconsumption of this nutrient can promote inflammation and may be associated with an increased risk of heart disease. Also Read – Add new books to your shelf”It is important for pregnant women to consider their diet, and our research is yet another example that potentially consuming too much of a certain type of nutrient can have a negative impact on the growing baby,” said study lead author Deanne Skelly, Professor at Griffith University in Australia. The finding, published in The Journal of Physiology, found that eating a diet with three times the recommended daily intake of linoleic acid might be harmful in pregnancy. Also Read – Over 2 hours screen time daily will make your kids impulsiveFor the study, the researchers picked rats for the experiment and they found three changes in rat mothers who ate a high linoleic acid diet: their liver had altered concentrations of inflammatory proteins, their circulating concentrations of a protein that can cause contraction of the uterus during pregnancy were increased, and a hormone that can regulate growth and development was decreased. If the effects of high linoleic acid are the same in rats and humans, this would suggest that women of child-bearing age should consider reducing the amount of linoleic acid in their diet. During the study, the research team fed rats for 10 weeks on a diet with high linoleic acid, mated them and then investigated the effects of the diet on their pregnancy and developing babies. Rats typically give birth to multiple babies in each pregnancy. Rat mothers who ate a high linoleic acid diet had a reduced number of male babies, said the study. It is important to note that when humans eat a diet rich in linoleic acid, the diet also tends to be high in fat, sugar, and salt. However, in the study, the only change in the diet was higher linoleic acid, but no changes in fat, sugar or salt.
Despite the fact that Antarctica was discovered, or at least spotted, in 1820, the first time man set foot on the continent proper wasn’t until Alexander von Tunzelmann in 1895, according to the New Zealand government’s website, New Zealand History. That same year, the Sixth International Geographical Congress met in London and adopted a resolution to the effect that the Antarctic was the greatest piece of geographical exploration that had yet to be taken on, and the Heroic Age of Antarctic Exploration began. From 1895 until about 1917, when Shackleton’s expedition on the Endurance went awry, there were a number of expeditions to that region, all aimed at exploration and scientific research.Dogs watching Endurance in the final stages of its drift, shortly before it sank to the bottom of the Weddell SeaAlong with the two-footed explorers and adventurers, there were also travelers of the four-footed variety who provided not only a means of transportation for men heading into the interior but also a source of companionship.The name “husky” is often used to describe a number of breeds of northern-hemisphere snow dogs. The dogs originated in Labrador and Greenland and have thick, double-layered coats that make them especially well-suited to the sorts of extreme weather conditions found in environments like the Antarctic.Photograph of the Weddell Sea Party on board the EnduranceAccording to Cool Antarctica, the first Huskies to be used in the Antarctic were brought to the continent by the British Antarctic Expedition. Shortly after the expedition arrived at Cape Adare in February 1889, a four-day blizzard blew in and caused seven of the men to be stranded on shore. Those men survived the bitter conditions by erecting a large tent they had with them and bringing all 75 of their dogs into it with them to keep warm. It was a strong and vivid first encounter demonstrating how crucial the canines were to man’s survival on the continent.In April, one of the team’s dogs got stranded on an ice floe and was blown out to sea. The team thought the dog was a goner, but it returned about two and half months later, and in good condition, showing how well-suited huskies are to the climate.Roald Amundsen’s Antarctic expedition.The dogs were used to pull sleds during treks around the continent; sledges were the only viable method of transportation before mechanical transports.When motorized vehicle transport became an option, which happened much later in Antarctica than elsewhere in the world, dogs and sledges remained popular, as they were more reliable in the harsh weather. Also, they were better company.Husky dogs in sled at Rovaniemi forest, in winter Finland, LaplandAccording to the website of the Australian Antarctic Division, the Australians built Mawson Station in 1954 as part of the country’s Antarctic program. When the station was established, they brought in a number of huskies for transport and companionship purposes, and dogs remained a working part of base operations for the next 40 years.Bases operated by other nations also continued to use sled dogs through the 1960s and into the ‘70s, as the animals were quick, agile, and not put off by the lack of established trails, let alone roads.Celebrated sled dog Balto with Gunnar Kaasen. Norwegian immigrant Gunnar Kaasen was the musher on the last dog team that successfully delivered diphtheria antitoxin to Nome, Alaska in 1925. Balto was the lead dog for that final leg of 53 miles of the total 674-mile trip.Slowly, snowmobiles began to become more common and the use of dog sleds started to diminish, although a number of bases kept some dogs anyway, as a backup to mechanized transport or for the sheer fun of it.That continued until 1991, when the members of the Antarctic Treaty began implementing the Protocol on Environmental Protection. One of the items the protocol required was the banning of all non-indigenous species except humans. This was due to fears of disease outbreaks occurring which could easily have devastating effects across Antarctica.Photo by Nasjonalbiblioteket CC BY 2.0The iconic Huskies had to go. The following year, the last half-dozen remaining sled dogs at Mawson station left Antarctica for good. It was an end of an era. The older dogs were retired to Australia, where they could live out the rest of their years in comfort, and the younger animals were taken to Minnesota to be trained as working dogs.Even though the era of the Antarctic sled dog is long over, the furry explorers haven’t been forgotten. A bronze sculpture of a husky sled dog was erected in front of the British Antarctic Survey headquarters in Cambridge, England in 2009. The funds for the sculpture were raised by three of the men who lived and worked with the dogs in Antarctica.Read another story from us: Europe’s Most Beautiful Christmas MarketsIn Antarctica itself, many of Mawson’s Huskies were remembered when their names were given to 26 landmarks in Antarctica in 2017, including various reefs, rocks, and islands. Those memorials are a lasting legacy to remember the creatures that proved to be such an integral part of the continent’s exploration.
True heroes are men and women who go about their jobs with little fanfare and even less personal reward, even though those jobs may cost them their lives. Fire fighters, police officers, and others in similar professions who put their lives on the line each and every day deserve to be saluted as heroes; even if they are never personally in jeopardy, they make a promise to lay down their lives if the circumstances arise.They protect society — that is the fundamental promise each one makes when they take on the mantle of public servant.Duga radar station, ChernobylThere is no better, or unusual, example of everyday heroes than the men who waded into the unknown blackness of a basement in Chernobyl after the accident that is considered the worst nuclear disaster in history, in April 1986. The three men are known collectively as the “suicide squad” because they thought first of national safety and put their own lives at risk to stop the disaster from worsening.Without their actions, Chernobyl would have been an even worse event, spreading radiation poisoning across most of Europe and making an enormous area virtually unlivable.Cold War Duma Radar Station, ChernobylWhen one of the nuclear reactors exploded, a combination of human failings and design problems was blamed. But thanks to the actions of three volunteers, a terrible situation was prevented from becoming completely untenable.A pool of water sat beneath a second reactor, and the flow of molten, radioactive metal was rapidly approaching it. If the two made contact, an explosion would ensue that would have led to mass evacuations and radiation sickness; some suggest it may have wiped out half of Europe.View of the horizon from inside the abandoned gym in Prypyat ghost town, ChernobylAndrew Leatherbarrow is the author of 1:23:40: The Incredible True Story of the Chernobyl Nuclear Disaster. In late April, he told Business Insider that, “if that had happened (contact) it would have triggered a second steam explosion that would have done unimaginable damage and destroyed the entire power station, including the three other nuclear reactors.” To stop that from happening, workers had to drain the water that was sitting beneath the reactor.But the basement had flooded, and accessing the pipes and taps was difficult and dangerous.Aerial panorama view of Chernobyl exclusion zone with ruins of abandoned Pripyat cityEnter the “suicide squad,” as popular lore has nicknamed the men who bravely stepped forward to accept the risk. They were told that, should anything happen to them, the state would look after their families as a symbol of gratitude.Although the story of what they did has taken on almost mythic proportions, they did indeed act selflessly and in an extraordinary way that would give the average individual pause.Because the basement was highly radioactive, the men donned wetsuits, and, according to urban legend, all three died shortly thereafter of Acute Radiation Syndrome (ARS). The truth is somewhat less dramatic, Leatherbarrow explained. None of the men died of ARS, and, in fact, one continued working in the industry.Abandoned machinery inside the Chernobyl Nuclear Power Plant Zone of AlienationFirefighters had drained some of the water from beneath the reactor and so, while it was knee-deep, at least the men were able to navigate the hallway. One of them, engineer Alexei Ananenko, told Leatherbarrow that they used a flashlight to find their way to the shut off valves. “When the search light fell on a pipe, we were joyous,” he explained, “because the pipe led to the valves.”In the book, which Leatherbarrow spent five years researching and writing, he acknowledges that “the basement entry, while dangerous, wasn’t quite as dramatic as modern myth would have you believe.” But, he insists, in no way does that diminish the heroic actions of the men. “They still went down into a pitch black, damaged basement beneath a molten reactor core that was slowly burning its way down to them.”“Chernobyl Nuclear Power Plant Zone of Alienation is an exclusion zone around the site of the Chernobyl nuclear reactor established by the USSR soon after the disaster in 1986”Alexei Ananenko, Valeri Bezpalov, and Boris Baranov volunteered for a task that could very well have meant the end of their lives. Without their courageous act, millions more would have died because of Chernobyl, not just in the immediate vicinity, but throughout Europe.Read another story from us: The People who Live in Chernobyl’s Radioactive Disaster ZoneThese three “everyday heroes,” just doing their job, are hardly “everyday.” They acted without thought of their own welfare, and for no personal gain. True heroes, indeed.
Unrealistic expectations caused the Tennessee coaching disasterSince yanking the rug out from under Greg Schiano in reaction to an angry fan base, Tennessee has been rejected by a number of coaches, and the search has turned turned into a dumpster fire.Colin thinks Vols fans had unrealistic expectations about landing Jon Gruden have led to the discontent among fans, who are unwilling to readily accept a lower profile coach. With their treatment of Schiano, the fan base has now made this job toxic for any big name, and it’s hard to have sympathy for them. Eli Manning’s consecutive games streak isn’t a reason to keep starting himAfter his benching by the Giants, many defenders of Eli Manning argued that his 210 consecutive starts should have been taken into account as a representation of his dedication to the franchise.Colin disagrees, and thinks that Manning’s consistency in playing every week doesn’t outweigh the reality that he’s been playing poorly for years. Even though Eli was consistent in showing up every week, his play has been inconsistent. Benching him was the right move for the organization, even if it was unpopular with some.Guests:Stephen Jackson – NBA Analyst and NBa Champion is in-studio discussing the Thunder’s struggles; why he respects LeBron; and why he was impressed with Lonzo against the Warriors.Greg Cosell – Films Senior Producer joins the show to look at the film on Dak Prescott’s struggles; why Alvin Kamara may be the best dual threat running back in the NFL right now;Mark Schlereth – FS1 Analyst and Fox NFL Commentator is in-studio talking about a potential Aaron Rodgers return; why Aaron Rodgers injury shows how much he carries the franchise;Bucky Brooks – NFL Analyst and former NFL scout is in-studio to discuss if the Redskins should re-sign Kirk Cousins; and thoughts on Eli’s benching in New York.
Advertisement Minor league umpires are used to getting booed for making bad calls, but fans of the Triple-A Las Vegas Aviators found a new reason to give an ump the business for his treatment of the team’s beloved bat dog.The unusual booing occurred after the home plate umpire tossed a bat to the on-deck circle instead of letting Finn the Bat Dog perform his sacred duty of fetching the bat and bringing it to the dugout. The crowd shaming was swift and fierce, in the form of a sound booing.Umps just can’t win.Might be the loudest boo in the history of umpire’s. I still love you guys though!! @MiLB @SportsCenter @MLB @AviatorsLV @LVBallpark @notthefakeSVP #umpire pic.twitter.com/ACsm88seKi— Finn The Bat Dog (@finnthebatdog) April 10, 2019
Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. min read What it is: Rocket Lawyer is a legal resource that attempts to create and manage legal documents. It is based on a series of free, interactive legal templates that can be adapted to your company’s specific legal needs. Rocket Lawyer also lets users draft, save and share legal documents using the service.For more advanced legal conundrums — such as translating lengthy insurance contracts into plain English or penning multi-vendor outsourcing agreements — there is a subscription fee. Once you’ve signed up for the subscription service, you can submit documents for review by Rocket Lawyer-affiliated attorneys and get access to free phone consultations, discounted hourly fees and flat rates for legal filings such as name changes or corporate restructuring.Discounted subscriptions start at $9.99 per month for a year-long personal legal plan and $24.99 per month for a business legal plan.Why you might like it: Rocket Lawyer is jam-packed with legal tools and features that make drafting sophisticated legal documents a cinch, without much professional legal help. And overall, the new On Call feature provides added value. We found that it referred us to what appeared to be reasonably qualified attorneys much more efficiently than the previous methods for brokering that relationship.More importantly, Rocket lawyer documents have not led to any disputes at my firm in the more than two years I’ve used the service. And I don’t expect that to change.Why you might not like it: The service has a subtle but powerful limitation: It is not clear who employs the lawyer Rocket Lawyer refers you to. Yes, you and your clients or business partners can create sophisticated, legally binding documents. But when the virtually summoned lawyer appears, so does an eerie question: From what perspective is this virtual lawyer offering advice? The business owner? The employee? The client? As Rocket Lawyer’s real lawyers may have varied allegiances, utilizing their services may turn out to be less valuable than you might expect. Moreover, I found that documents I created on my own from the free service to be perfectly serviceable — making the paid service not all that useful.What to do: By all means, if you are looking to save a ton of money on legal services, use Rocket Lawyer. You will find it fast, easy and vastly cheaper than dealing with traditional legal services. Just don’t be surprised if you start using Rocket Lawyer’s free documents directly and stop paying for the full service entirely.Have you found Rocket Lawyer or other online legal-form providers helpful for running your business? If so, let us know how in the comments section. Unless you’re something of a legal eagle — or married to one — you’re probably going to need some advice from a lawyer at some point. The trouble is, paying a pricey attorney may not be in the budget.
