The HT-S350 comes with a wireless subwoofer. Sony Sony has detailed pricing on one of the sound bars announced at CES 2019 — the HT-S350 — while the Dolby Atmos X8500 is yet to receive a release date.The $280 HT-S350 sound bar lacks any smart features (such as a voice assistant) but includes a wireless subwoofer and a claimed 320 watts of power. Unlike competitors that now use DTS Virtual:X, the HT-S350 uses Sony’s proprietary S-Force Pro Front Surround technology. The sound bar also uses an HDMI ARC connection and carries Bluetooth.Meanwhile, the X8500 is a 2.1-channel single sound bar with dual built-in “subwoofers” and the ability to simulate Atmos effects with its Vertical Surround Engine. The sound bar also includes other sound options including Cinema Mode, Game Mode and vocal enhancement. Connectivity includes HDMI eARC support for compatible televisions such as the 2019 Sony range in addition to Bluetooth. Sony Sony didn’t announce any “smart” audio products at the show, unlike LG and Klipsch with their smart sound bars.The HT-S350 will be available at the end of April, but the company hasn’t announced pricing or availability for the X8500.

Yemeni pro-government forces stand next to a pickup truck carrying anti-aircraft guns along they way to al-Durayhimi district, about nine kilometres south of Hodeidah international airport on 13 June 2018. Photo: AFPYemeni forces backed by a Saudi-led coalition launched an offensive Wednesday to retake the rebel-held port city of Hodeida, a key aid hub, sparking calls from the international community for restraint.Pro-government troops began the assault despite mounting international fears about the humanitarian fallout, pressing toward Hodeida airport south of the city after receiving a “green light” from the coalition.By Wednesday night, the offensive remained on the outskirts of the rebel-held airport.The Red Sea port, controlled by the Iran-backed Huthi rebels who hail from northern Yemen, serves as the entry point for 70 per cent of the impoverished country’s imports as it teeters on the brink of famine.The official United Arab Emirates news agency WAM confirmed that the operation was ongoing “with the participation and the support, through land and sea and air, of the Emirati armed forces”.It added that the attacking forces managed to “liberate areas… in the surroundings of the airport” and captured and killed “dozens of Huthi” rebels.The UN Security Council will meet on Thursday for urgent talks on the offensive, diplomats said, after a request from Britain. The closed-door meeting will be the second this week on the Yemen crisis.The request came after the UN envoy for Yemen, Martin Griffiths, said he was still holding negotiations on keeping the key port open to aid deliveries.”We are in constant contact with all the parties involved to negotiate arrangements for Hodeida that would address political, humanitarian, security concerns of all concerned parties,” he said.The European Union’s foreign policy chief warned of the “devastating” impact the assault would have.”The latest developments will only lead to further escalation and instability in Yemen,” Federica Mogherini said in a statement.The coalition insisted its humanitarian aid response would go in parallel with military operations.- Huthis fan out -Two Saudi and UAE aid ships were in the waters off Hodeida, coalition spokesman Turki al-Maliki told Saudi state media.The two countries also said they would operate a dedicated shipping lane to Hodeida from Abu Dhabi and the southern Saudi city of Jizan to deliver food and medical supplies.In Hodeida, people waited anxiously for the fighting to reach their neighbourhoods. Those contacted by AFP said Huthi fighters had fanned out across the city.Coalition sources said the alliance carried out 18 air strikes on Huthi positions on the outskirts of Hodeida on Wednesday.According to medical sources in the province, 22 Huthi fighters were killed by coalition raids, while three pro-government fighters were killed in a rebel ambush south of Hodeida.A bulldozer clears the way for a column of Yemeni pro-government forces arriving in al-Durayhimi district, about nine kilometres south of Hodeidah international airport on 13 June 2018. Photo: AFPThe UAE armed forces said on Wednesday night that four Emirati soldiers were killed in Yemen, without specifying when and where.The city of Hodeida, home to 600,000 people, was captured by the insurgents in 2014 along with the capital Sanaa.Saudi Arabia, the United Arab Emirates and a bloc of other countries intervened in Yemen the following year with the goal of restoring the government to power.The coalition accuses the Huthis of using the port to secure Iranian arms, notably ballistic missiles the militants have increasingly fired into Saudi territory.Yemen’s government said Tuesday that negotiations had failed to force the rebels from Hodeida, and that a grace period for UN-led peace efforts was over.- Children in the crossfire -Emirati diplomats have insisted that similar large-scale offensives had improved the lives of Yemenis elsewhere.Hassan Taher, the official Hodeida governor based outside the city, said Wednesday that Yemen’s government would ensure aid deliveries throughout the offensive.”We want a rapid war, but it won’t be finished in two days,” Taher told AFP.The International Committee of the Red Cross said any battle for Hodeida would exacerbate the suffering of the population.”Life-saving items cannot be given to those in need while fighting is ongoing,” ICRC Middle East director Robert Mardini said in a statement.The UN children’s fund, UNICEF, has raised alarm over the plight of Hodeida’s 300,000 children and the risk that drinking water supplies will be disrupted.”UNICEF has pre-prepositioned supplies in Hodeida: over 20,000 basic hygiene kits… We hope we don’t need to use them,” its Yemen representative Meritxell Relano said on Twitter.The Huthi leadership on Tuesday called on the international community to “pressure a halt to the escalation”, warning an assault on Hodeida would put Red Sea navigation at risk.On Wednesday, the Huthis said they targeted a coalition warship off the coast of Hodeida with two missiles, with rebel outlet Al-Masirah claiming a direct hit.As the offensive got under way, Saudi Arabia’s ambassador to Yemen was defiant.”Hodeida will be liberated, and the Yemeni people will gain back a major artery of life,” he tweeted.

It found students in Texas public colleges have just a 40% chance of earning a degree within six years.Hiler says “dropout factories” is a term that’s long been applied to high schools, but colleges deserve the same critical scrutiny.“When a high school in this country is not graduating more than two-thirds of its student body,” says Hiler, “the federal government actually says that a state or a district has to intervene in that high school and put in place a support plan or an intervention plan to make sure that a school is paying attention in getting that graduation rate up. Yet, at the college level, no such comparable bar exists.”The study found that the University of Houston-Downtown had the lowest graduation rate in Texas – just 13 percent of U-H-Downtown students earn a degree within six years.But the school’s Interim President, Dr. Michael Olivas, says those numbers are misleading and don’t reveal the complete story.He says that almost half of the students at UHD are the first in their families to go to college and about two-thirds of its students end up transferring from other campuses or community colleges to UHD.Dr. Olivas says compared to where he’s employed, Texas’ top universities get a disproportionate share of resources.“When flagship schools in College Station and in Austin just as examples, are 50,000 students, “ UHD’s leader says, “who take mostly advantaged students and who are subsidized heavily by research grants as well as endowments that are long-established by law, the Permanent University Funds, I don’t think that everybody is going to have the same opportunities that they do.”Indeed, the report does show that the schools in Texas with the highest completion rates are Texas A&M in College Station followed by the University of Texas at Austin.Dr. Olivas adds that UHD charges the fifth lowest tuition in the state and students who do graduate from the school, finish with less debt.Hiler does acknowledge that the report only shows data for first-time, full-time students – not transfers or those students who are part-time.“The purpose of the study,” its co-author says, “is to shift conversations away from just cost, in a year when political candidates have been promising ‘free college tuition,’ but instead to a conversation of value – making sure we’re bringing value to students’ lives when they decide to enroll in a school and take out loans and sort of expect to have college be their ticket to the middle class.”The report also showed that Texas Southern University has the eighth-lowest completion rate of any four-year college in the nation and charges students more than the national average.TSU officials did not respond to a request for comment on the study.

Magnesium + Oxygen + Water + Salt + Additive = Direct Current Credit: MagPower Systems, Inc The MAFC (magnesium-air fuel cell) has the electrolyte versatility of using a common saline (salt) solution or ocean water. The performance capabilities of the MAFC can be enhanced through the addition of MagPower’s hydrogen inhibitors.According to MagPower Systems, by using hydrogen inhibitors the MAFC has increased power efficiency, lower cell resistance, and the reduction or elimination of pressure and/or volume increase due to hydrogen gassing resulting in smaller metal-air fuel cells, and batteries.Magnesium is highly reactive and stores a lot of energy. Researchers are now devising ways to extract energy from magnesium in a more controlled method. (PhysOrg.com) — There is enough magnesium to meet the world’s energy needs for the next 300,000 years, says Dr. Takashi Yabe of the Tokyo Institute of Technology. Citation: Magnesium: Alternative Power Source (2010, April 23) retrieved 18 August 2019 from https://phys.org/news/2010-04-magnesium-alternative-power-source.html Magnesium is abundant in the world; however the production of magnesium is neither cheap or clean. There are various ways of extracting magnesium, ranging from an electrolytic process to high temperature method called the Pidgeon process.Dr. Yabe has devised a high temperature solution by concentrating solar collectors and a solar-pump laser to reach a temperature of 3,700 degrees centigrade. This high heat method is used to burn magnesium oxide extracted from seawater. The solar-pumped laser is necessary to help obtain this high temperature because concentrated solar energy alone would not be enough to generate 3,700 degrees C. Engineers at MagPower have developed a metal-air cell that uses water and ambient air to react with a magnesium anode, to generate electricity. A magnesium based version of the lithium-ion rechargeable cell has been created by Dr. Doron Aurbach at Bar-Ilan University in Israel. © 2010 PhysOrg.com
Citation: Study suggests a big increase in Arctic precipitation over the coming century, much of it rain (2017, March 16) retrieved 18 August 2019 from https://phys.org/news/2017-03-big-arctic-precipitation-century.html Journal information: Nature Climate Change © 2017 Phys.org Mosaic of images of the Arctic by MODIS. Credit: NASA Humans to blame for bulk of Arctic sea ice loss: study Explore further (Phys.org)—A pair of researchers with the University of Groningen in the Netherlands has found via climate modeling that it appears likely that the Arctic is likely to see substantially more precipitation over the next century, much of it in the form of rain. In their paper published in the journal Nature Climate Change, Richard Bintanja and Olivier Andry describe their results when running 37 climate models programed to describe Arctic conditions over the years 2091 to 2100. More information: R. Bintanja et al. Towards a rain-dominated Arctic, Nature Climate Change (2017). DOI: 10.1038/nclimate3240AbstractClimate models project a strong increase in Arctic precipitation over the coming century, which has been attributed primarily to enhanced surface evaporation associated with sea-ice retreat. Since the Arctic is still quite cold, especially in winter, it is often (implicitly) assumed that the additional precipitation will fall mostly as snow. However, little is known about future changes in the distributions of rainfall and snowfall in the Arctic. Here we use 37 state-of-the-art climate models in standardized twenty-first-century (2006–2100) simulations to show a decrease in average annual Arctic snowfall (70°–90° N), despite the strong precipitation increase. Rain is projected to become the dominant form of precipitation in the Arctic region (2091–2100), as atmospheric warming causes a greater fraction of snowfall to melt before it reaches the surface, in particular over the North Atlantic and the Barents Sea. The reduction in Arctic snowfall is most pronounced during summer and autumn when temperatures are close to the melting point, but also winter rainfall is found to intensify considerably. Projected (seasonal) trends in rainfall and snowfall will heavily impact Arctic hydrology (for example, river discharge, permafrost melt), climatology (for example, snow, sea-ice albedo and melt)8, 9 and ecology (for example, water and food availability). Over the past several years, climate scientists have been running various models in different ways trying to understand why Arctic sea ice continues to melt faster than models predict. In this new effort, the researchers took a closer look at the impact caused by changes in the amount of precipitation. They combined data from a variety of sources and used it to run 37 climate models, finding that the Arctic is likely to see an increase in precipitation by as much as 4 percent, which is double that for the rest of the planet. They note that retreating ice leaves more open water, which leads to more evaporation and more snow and rainfall. The models suggested the rainy season in the Arctic will likely last longer in the future and reach farther north. They also theorize that sometime in the next century, it will be possible to navigate a ship to the North Pole because all of the sea ice will be gone.In another study, an international team of researchers ran models of their own and concluded that almost half of the ice that has melted in the Arctic over the past century and a half may be attributed to natural changes such as variations in wind and water currents. They have also published their results in Nature Climate Change. They suggest that the reason so many climate models have failed to accurately predict how much ice would melt in the Arctic and when is because they fail to account for natural climate variations. They believe the Arctic is currently experiencing a natural warm spell, which, when combined with human-caused global warming, is causing ice to melt at very fast rate.
