What do astronauts do on International Space Station?


 to read online news all bangla newspaper

Italy's first female space explorer, Samantha Cristoforetti, is spending just about six months on the International Space Station.


The European Space Agency space explorer touched base at the circling space lab on Monday, alongwith two crewmates from Russia and America. 



Yet, what precisely will she be doing amid her time in space?
The ISS allows to do logical investigations that is impossible on Earth, as the station offers a domain of microgravity.
Here we gone through a couple of cases of the trials on Samantha's schedule...
Electromagnetic levitator
Samantha will work a device called an electromagnetic levitator, which can warm metals to 2,000°C and after that cool them rapidly.
This will be an opportunity to perceive what happens to various metals when they go from fluid to strong, without the impact of the Earth's gravity.
It's trusted the outcomes will uncover more about the material science of the metals and how they function.
Testing innovation
Samantha will test new machine innovation and how well they function in space, for example, this space explorer joystick.

Utilizing a joystick in space may feel altogether different in space contrasted with on Earth.So these tests will perceive how being in space may influence how well a space traveler can control a space robot or space hardware.


Something else is that hardware may should be appended to the space explorer so it doesn't glide away. The testing will likewise observe what affect this has.
Restorative research
Samantha will do bunches of trials to perceive how being in space influences her body.
For instance, she will encounter 16 dawns and dusks each day on the International Space Station and be tried to perceive how this influences her body clock.
Another imperative subject is sustenance and vitality. Examinations to perceive how much sustenance a space traveler would requirement for a long mission will be completed. Samantha will record what she eats and her vitality levels over a timeframe.


Different things that will be taken a gander at incorporate how space influences skin and why numerous space travelers get cerebral pains.

Natalie St. Clair is a travel agent for women seeking an abortion



 NATALIE St. Clair's employment isn't a simple one. Since at 24-years of age, the youthful Texan is the operations director of the Fund Texas Choice — a non-benefit that helps and masterminds travel prerequisites and assets for ladies looking for a premature birth. St. Clair, who alludes to herself as a fulltime 'fetus removal travel operator' — arranged more than 300 premature birth trips over her state in 2016 alone — a number that she says, as indicated by Refinery 29, tripled since 2014. Joining the association three years prior as a volunteer, St. Clair's part is the one-quit arranging place for

everything a lady may require. On the off chance that they require a transport, or an inn — a Uber or whatever other type of support — St. Clair is there at all times. "I'm all the more a truly irritating travel mate who you can be in contact with while you get your fetus removal," she said. St. Clair, who says the part is brimming with "messaging and faxing" said arranging a fetus removal in her home condition of Texas is "thoroughly overpowering". In 2013, the state shut more than 40 fetus removal facilities when legislators started pushing for new limitations. From meeting doctor's facility like norms, (for example, least size rooms and entryways) to pipelines for anesthesia, centers started to close their entryways when they were not able meet the predetermined necessities of the House Bill 2 law. Texas, which has more than 5.4 million ladies of conceptive age, was left with only 19 facilities over the 695,662 km² state. A review, distributed in the American Journal of Public Health, dissected study reactions from almost 400 ladies who had premature births at 10 Texas centers amongst May and August of 2014. Ladies whose closest facility shut after House Bill 2 needed to travel a normal of 135 kms one-approach to look for a fetus removal. Under the watchful eye of the law was actualized, the closest facility for these ladies was found just 27km away by and large. As indicated by the review, a quarter lived more than 223km from the closest supplier and 10 for every penny lived more than 214km away. While the U.S. Preeminent Court dropped the limitations contained in the law, House Bill 2, last June, the facilities have neglected to revive. "A few people call us having no clue where they can get a premature birth," St. Clair disclosed to Refinery 29. "A great deal of times, somebody has an arrangement in a town that is not the nearest one to them. We'll say, 'Really one's 200 miles nearer. "You'll need to travel way less and it will be a considerable measure less demanding.' Once they've made their arrangement, we book the travel." A week ago, US
 President Donald Trump marked a request that could limit ladies over the world access to safe fetus removal. The new President reestablished the Mexico City arrangement as one of his first moves in the White House, days after the initiation. The arrangement authorizes a prohibition on giving government cash to universal gatherings that perform premature births or advance the alternative.That implies any US governmentally supported guide amass or other non-government 

association can't help with, prescribe, give counsel or give any data with regards to the crisis end strategy. The arrangement likewise precludes citizen subsidizing for gatherings that anteroom to sanction fetus removal or advance it as a family arranging technique. These progressions have made St Clair's work all the more fundamental, and expanding sought after. St. Clair said the principal thing she will do when drew closer by a lady is see if she knows how to achieve a center. In the event that the appropriate response is no, St. Clair gives her hands something to do.

"I generally check the transport first," St. Clair said. "In any case, a ton of times, [the bus] isn't a sensible choice, in light of the fact that there are three exchanges and it will take 9 hours. "So if there's nothing there, then I say 'Hello, do you know whether you could have a companion you could drive with in the event that we paid them to drive you?'" St. Clair said that the truth of ladies looking for a fetus removal in Texas is a terrifying, and regularly desolate experience — that frequently observes ladies resting in their auto overnight after the system. "I never need someone getting a fetus removal and afterward dozing in their auto a short time later," she said. "That is not alright. Furthermore, that is an immense hazard to wellbeing and wellbeing in general." St. Clair, who said she is dependably available to come back to work for every one of the ladies who utilize their administration, began with the non-benefit when she was only 21-years of age and says she has never met one of the ladies she has helped face to face. "Everyone expresses gratitude toward me," St. Clair said. "'This made everything go a lot more easily,' is something I hear a considerable measure. Some will inquire as to whether the inn is pet-accommodating on the grounds that they have a pooch that they can't leave at home, so we'll discuss our pets. "One individual and I really traded photographs of our felines. [At the finish of the day,] you're simply having a discussion with someone." St. Clair said that their administrations basically provide food for individuals who might need to surrender, and dread of the impediments they lie ahead. "We are here to ensure they can get the premature birth on the off chance that they need the fetus removal, and to help them traverse each of those means," she said. online redio all bangla newspapers

Best Veterans History

The main auto in central europe was created by czech organization
Best veteran era
The main generation of vehicles was by Karl Benz in 1888 in Germany and, under permit from Benz, in France by Emile Roger. There were various others, including tricycle developers Rudolf Egg, Edward Butler, and Léon Bollée., utilizing a 650 cc (40 cu in) motor of his own outline, empowered his driver, Jamin, to normal 45 kilometers for each hour (28.0 mph) in the 1897 Paris-Tourville rally. By 1900, large scale manufacturing of autos had started in France and the United States.Read the newspaper all bangla newspaper

The main engine auto in Central Europe was created by Czech organization Nesselsdorfer Wagenbau (later renamed to Tatra) in 1897, the Präsident automobil. The principal organization framed solely to manufacture vehicles was Panhard et Levassor in France, which likewise presented the initial four-chamber motor. Framed in 1889, Panhard was immediately trailed by Peugeot two years after the fact. By the begin of the twentieth century, the vehicle business was starting to take off in Western Europe, particularly in France, where 30,204 were delivered in 1903, speaking to 48.8% of world car generation that year.In the United States, siblings Charles and Frank Duryea established the Duryea Motor Wagon Company in 1893, turning into the primary American vehicle fabricating organization. The Autocar Company, established in 1897, built up various advancements still in use and remains the most seasoned working engine vehicle maker in the United States However, it was Ransom E. Olds and his Olds Motor Vehicle Company (later known as Oldsmobile) who might command this time of car generation. Its creation line was running in 1901. The Thomas B. Jeffery Company built up the world's second mass-delivered car, and 1,500 Ramblers were constructed and sold in its first year, speaking to one-6th of every current motorcar in the United States at the time. Within a year, Cadillac (framed from the Henry Ford Company), Winton, and Ford were additionally creating autos in the thousands.

Inside a couple of years, a confounding variety of advancements were being created by several makers everywhere throughout the western world. Steam, power, and petrol/fuel controlled autos went after decades, with petrol/gas inside ignition motors accomplishing predominance in the 1910s. Double and even quad-motor autos were outlined, and motor relocation extended to more than twelve liters. Numerous present day propels, including gas/electric half breeds, multi-valve motors, overhead camshafts, and four-wheel drive, were endeavored, and disposed of as of now.

In 1898, Louis Renault had a De Dion-Bouton changed, with altered drive shaft and differential, making "maybe the primary speedster ever" and bringing Renault and his siblings into the auto industry.[24] Innovation was fast and widespread, with no reasonable benchmarks for fundamental vehicle designs, body styles, development materials, or controls. Numerous veteran autos utilize a tiller, instead of a wheel for guiding. Amid 1903, Rambler institutionalized on the controlling wheel and moved the driver's position to one side hand side of the vehicle. Most autos were worked at a solitary speed. Chain drive was overwhelming over the drive shaft, and shut bodies were to a great degree uncommon. Drum brakes were presented by Renault in 1902. The following year, Dutch creator Jacobus Spijker constructed the initial four-wheel drive hustling car; it never contended and it would be 1965 and the Jensen FF before four-wheel drive was utilized on a generation auto.Read news  all bangla news paper
Development was not restricted to the vehicles themselves, either. Expanding quantities of autos pushed the development of the petroleum industry, and also the advancement of innovation to create fuel supplanting lamp fuel and coal oil and of changes in warmth tolerant mineral oil greases supplanting vegetable and creature oils.

There were social impacts, too. Music would be made about autos, for example, "In My Merry Oldsmobile" (a convention that proceeds) while, in 1896, William Jennings Bryan would be the principal presidential contender to battle in an auto (a gave Mueller), in Decatur, Illinois. Three years after the fact, Jacob German would begin a custom for New York City cabdrivers when he sped down Lexington Avenue, at the "rash" speed of 12 mph (19 km/h). Also in 1899, Akron, Ohio, received the main self-moved paddy wagon.By 1900, the early focuses of national car industry created in numerous nations, including Belgium (home to Vincke, which duplicated Benz; Germain, a pseudo-Panhard; and Linon and Nagant, both in view of the Gobron-Brillié) Switzerland (drove by Fritz Henriod, Rudolf Egg, Saurer, Johann Weber, and Lorenz Popp) Vagnfabrik AB in Sweden, Hammel (by A. F. Hammel and H. U. Johansen at Copenhagen, in Denmark, which just constructed one auto, ca. 1886, Irgens (beginning in Bergen, Norway, in 1883, yet without success),[7]:p.25–26 Italy (where FIAT began in 1899), and as far abroad as Australia (where Pioneer set up shop in 1898, with an officially old paraffin-fuelled focus rotate guided wagon).[7] Meanwhile, the fare exchange had started, with Koch sending out autos and trucks from Paris to Tunisia, Egypt, Iran, and the Dutch East Indies.

On 5 November 1895, George B. Selden was conceded a United States patent for a two-stroke car motor (U.S. Patent 549,160). This patent accomplished more to frustrate than energize advancement of automobiles in the United States Selden authorized his patent to most significant American automakers, gathering an expense on each auto they created. The Studebaker siblings, having turned into the world's driving makers of steed drawn vehicles, made a move to electric cars in 1902, and fuel motors in 1904, additionally kept on building horse-drawn vehicles until 1919.[34]:p.90 In 1908, the primary South American car was implicit Peru, the Grieve.[35] Motor autos were likewise sent out ahead of schedule to British settlements and the principal engine auto was traded to India in 1897.

All through the veteran auto period, be that as it may, the vehicle was considered more to be a curiosity than as a really valuable gadget. Breakdowns were visit, fuel was hard to acquire, streets appropriate for voyaging were rare, and fast advancement implied that a year-old auto was about useless. Significant achievements in demonstrating the value of the car accompanied the noteworthy long-remove drive of Bertha Benz in 1888, when she voyaged more than 80 kilometers (50 mi) from Mannheim to Pforzheim, to make individuals mindful of the capability of the vehicles her better half, Karl Benz, produced, and after Horatio Nelson Jackson's fruitful cross-country drive over the United States in 1903.

The 1908 New York to Paris Race was the primary circumnavigation of the world via vehicle. German, French, Italian and American groups started in New York City February 12, 1908 with three of the contenders at last achieving Paris. The US constructed Thomas Flyer with George Schuster (driver) won the race covering 22,000 miles in 169 days. While different automakers furnished drivers with tire repair packs, Rambler was first in 1909 to outfit its autos with an extra tire that was mounted on a fifth wheel. Click on bangla news papers

best history


Read the newspaper all Bangla Newspaper. Early endeavors at making and utilizing inner burning motors were hampered by the absence of reasonable fills, especially fluids, along these lines the soonest motors utilized gas blends.

Early experimenters utilized gasses. In 1806, Swiss architect François Isaac de Rivaz manufactured a motor controlled by interior ignition of a hydrogen and oxygen blend. In 1826, Englishman Samuel Brown tried his hydrogen-fuelled inward burning motor by utilizing it to drive a vehicle up Shooter's Hill in south-east London. Belgian-conceived Etienne Lenoir's Hippomobile with a hydrogen-gas-fuelled one-chamber inside ignition motor made a test drive from Paris to Joinville-le-Pont in 1860, covering somewhere in the range of nine kilometers in around three hours. A later form was pushed by coal gas. A Delamare-Deboutteville vehicle was protected and trialed in 1884.

Around 1870, in Vienna, Austria (then the Austro-Hungarian Empire), creator Siegfried Marcus put a fluid fuelled inside ignition motor on a straightforward pushcart which made him the main man to drive a vehicle by method for gas. Today, this auto is known as "the main Marcus auto". In 1883, Marcus secured a German patent for a low-voltage start arrangement of the magneto sort; this was his exclusive car patent. This outline was utilized for every single further motor, and the four-situate "second Marcus auto" of 1888/89. This start, in conjunction with the "turning brush carburetor", made the second auto's outline extremely creative. Read news all bangla newspapers.

It is for the most part acknowledged[according to whom?] that the primary truly down to earth autos with petrol/gas controlled inside burning motors were finished all the while by a few German innovators working autonomously: Karl Benz assembled his first vehicle in 1885 in Mannheim. Benz was conceded a patent for his vehicle on 29 January 1886, and started the primary creation of cars in 1888, after Bertha Benz, his significant other, had demonstrated – with the principal long-remove trip in August 1888, from Mannheim to Pforzheim and back – that the horseless mentor was totally appropriate for day by day utilize. Since 2008 a Bertha Benz Memorial Route remembers this event.[citation needed]

Before long, Gottlieb Daimler and Wilhelm Maybach in Stuttgart in 1889 outlined a vehicle starting with no outside help to be a car, as opposed to a steed drawn carriage fitted with a motor. They likewise are normally credited with innovation of the main cruiser in 1886, yet Italy's Enrico Bernardi of the University of Padua, in 1882, protected a 0.024 drive (17.9 W) 122 cc (7.4 cu in) one-barrel petrol engine, fitting it into his child's tricycle, making it no less than a possibility for the primary vehicle, and first bike; Bernardi broadened the tricycle in 1892 to convey two grown-ups.

One of the initial four-wheeled petrol-driven autos in Britain was implicit Birmingham in 1895 by Frederick William Lanchester, who additionally licensed the circle brake; and the primary electric starter was introduced on an Arnold, an adjustment of the Benz Velo, worked somewhere around 1895 and 1898.

George F. Foss of Sherbrooke, Quebec manufactured a solitary barrel fuel auto in 1896 which he drove for a long time, disregarding city authorities' notices of capture for his "frantic shenanigans."

In all the turmoil, numerous early pioneers are about overlooked. In 1891, John William Lambert fabricated a three-wheeler in Ohio City, Ohio, which was decimated in a fire that year, while Henry Nadig built a four-wheeler in Allentown, Pennsylvania.

TRANSPORTATION AND GLOBAL WARMING

 TRANSPORTATION AND GLOBAL WARMING
Due to its close aggregate reliance on petroleum energizes, the U.S. transportation area is in charge of about 33% of our nation's atmosphere evolving emanations. All around, around 15 percent of artificial carbon dioxide originates from autos, trucks, planes, ships and different vehicles.Read the newspaper all bangla newspaper.

Diminishing transportation emanations is a standout amongst the most essential strides in battling an unnatural weather change — and answers for the transportation issue are as of now accessible. Our country needs to move far from fossil fuel-controlled vehicle reliance and the rural sprawl that goes with it — and toward option fills, option and open transportation, and better land-utilize examples to start decreasing our nation's aggregate vehicle miles voyaged every year. The Center is taking a shot at all parts of the transportation issue, from pushing for expanded mileage gauges to testing new sprawl advancements, utilizing existing laws and working for new controls to limit vehicle discharges and exploit elective fills innovation for the advantage of the planet.

Managing GREENHOUSE GAS EMISSIONS FROM VEHICLES AND RAISING NATIONAL FUEL ECONOMY STANDARDS

Autos, trucks and game utility vehicles driven by U.S. natives are at fault for around 66% of nursery gas emanations from the U.S. transportation part. As more traveler vehicles hit the streets, this contamination will increment significantly unless strict emanations decrease and efficiency arrangements are set up.Read news all bangla newspapers.

We're working for more grounded direction of both nursery contamination from autos through the Clean Air Act and higher efficiency gauges as per the Energy Policy and Conservation Act, two incompletely covering and complimentary statutory plans. As an individual from the vast offended party gather in Massachusetts v. EPA, we praised the Supreme Court's April 2007 choice announcing CO2 a contamination under the Clean Air Act and requesting the Environmental Protection Agency to step toward control by making what's known as the "danger discovering" — an organization assurance that a toxin "jeopardizes general wellbeing and welfare," driving specifically to controls on that poison. In spite of the Supreme Court's choice, the Bush organization oversaw through a progression of slow down strategies to put off any control of CO2 from vehicles until the following organization. In September 2009, the Obama organization reported the primary national arrangement to direct nursery gasses under the Clean Air Act for autos, light trucks and SUVs, and in December the EPA at last made it official that nursery gas discharges from autos and different sources imperil general wellbeing and welfare. TRANSPORTATION AND GLOBAL WARMING

We effectively tested the Bush organization's refusal to give California a chance to actualize its own, stricter-than-national tailpipe outflows constrains under the Clean Air Act, and in June 2009 the EPA issued a waiver to give California a chance to implement its own vehicle discharges rules, which likewise permitted twelve different states to authorize similar standards.

Mileage measures for cars, set by the Department of Transportation in accordance with the Energy Policy and Conservation Act, likewise affect the measure of CO2 radiated by vehicles. After real advances in the late 1970s, mileage stagnated and even relapsed for a very long while, in spite of the law's order to set efficiency guidelines at the "most extreme plausible level." Thankfully, in November 2007 the Center won a noteworthy claim against the Department of Transportation for neglecting to legitimately represent nursery gas emanations when it set nonsensically low national efficiency principles for pickup trucks and game utility vehicles. In December 2007, Congress ordered an expansion in efficiency to 35 miles for every gallon for all traveler vehicles by 2020. In September 2009, the Department of Transportation and Environmental Protection Agency proposed a control to build national gas-mileage measures for autos, trucks and SUVs by around 5 percent for every year.

After President Barack Obama took office, the organization shockingly reported that its own efficiency models would be about a mile for every gallon lower than Bush's. Not exactly a week later, the Center recorded suit to upset them, and in 2010 the organization reported its purpose to build mileage norms, with the most aggressive proposition raising them to around 37 miles for each gallon by 2017. Watch the video game. Click here bd news.

In August 2012, measures werefinalized that ordered achieving greatest gas mileage of 54.5 miles for each gallon by 2025. Be that as it may, once different credits and "adaptabilities" are represented, the assessed mileage drops to around 47 miles for each gallon. Autos are industrially accessible today that meet and surpass this standard.

There have been improvements, however they're sufficiently bad. The advancements as of now exist to significantly build our fuel effectiveness today to as high as 45 miles for every gallon — and we should exploit these advances so as to decrease environmental nursery gas focuses to 350 sections for each million and avoid atmosphere calamity. We earnestly need to move to half and half, module mixture and electric vehicles fueled by renewable vitality.

Decreasing EMISSIONS FROM VEHICLES OF AIR AND SEA

Autos aren't the main vehicles that contaminate — planes and marine vessels deliver an expansive part of the world's nursery gas emanations, and this commitment must be relied upon to increment. Airplane not just emanate 12 percent of CO2 outflows from U.S. transportation sources — they likewise transmit nitrogen oxides other than nitrous oxide, bringing on warming when radiated at high height. What's more, boats, other than discharging just about 3 percent of the world's CO2 (about as much as all of Canada emanates), are additionally a principle wellspring of nitrous oxide and dark carbon (ash).

In July 2008, after the Bush organization declined to react to our 2007 petitions to lessen discharges from planes and ships, the Center joined a coalition of preservation gatherings and state lawyers in documenting a notice of purpose to sue unless the Environmental Protection Agency addresses an unnatural weather change contamination from these sources.

Conveying GOVERNMENT FLEETS UP TO DATE

The U.S. central government has well over a large portion of a million vehicles, making up the biggest armada in the country. The objective of the Energy Policy Act of 1992 was to supplant 30 percent of U.S. transportation-related petroleum utilization with option fuel vehicles by 2010, and the Act requires that no less than 75 percent of vehicles obtained every year by government offices in significant metropolitan zones be elective fuel vehicles. Shockingly, government organizations have a background marked by disregarding this necessity.

In November 2005, the Center and Bluewater Network won a settlement of a claim against four government organizations for their inability to make the required buys of option fuel vehicles, in which the Department of Commerce, Department of Labor, Department of Transportation and Veterans Administration conceded their infringement of the Energy Policy Act and consented to follow the law. In 2006, a government judge dismisses a Department of Energy finding that elected organizations couldn't make a move to decrease fuel utilize in light of the fact that petroleum lessening objectives commanded by the Act were unachievable.

PUTTING OFF-ROAD VEHICLES ON THE AGENDA

Rough terrain vehicles have little, wasteful two-and four-stroke motors that discharge a lot of contamination, including carbon dioxide. In California alone, rough terrain vehicles retch out more than 230,000 metric huge amounts of carbon dioxide every year, equivalent to the outflows made by smoldering around 500,000 barrels of oil.Watch the video game. Click here  bangladesh newspaper.

The Center has been dynamic in getting the condition of California to address these emanations alongside those of different sources under the Global Warming Solutions Act, and we've distributed a report specifying the issue and its answers.
