At the event Google will have several software-based announcements like every year. This year’s I/O is different as alongside the software-based announcements for the first time there will be some hardware announcements too. Google will be launching cheaper Pixels at I/O 2019 aka the Pixel 3a and the Pixel 3a XL. Ahead of the official release almost everything about the two new Pixels has been leaked. A new leak now outs the full specs sheet of the Pixel 3a.The leak comes from popular leakster Roland Quandt. The specs sheet reveals each and every detail about the cheaper Pixel 3a. According to the specs sheet the Pixel 3a will come packed with a 5.6-inch Full HD+ display with 1080p screen resolution and a 18:9 aspect ratio. The leak further suggests that the Pixel 3a will come with OLED display, now with that it will be safe to say that the new Pixel will offer great multimedia experience to the users out there.The specs sheet further reveals that the Google Pixel 3a will be powered by Qualcomm Snapdragon 670 processor paired with up to 4GB of RAM. The specs sheet doesn’t reveal the storage details of the phone. The Pixel 3a is said to come packed with a 3000mAh battery setup and will have a polycarbonate build – this is understandable considering the price of the phone is expected to be much cheaper than the regular Pixels.advertisementCamera has always been the biggest highlight of the Google Pixel phones. The same is expected of the cheaper Pixel 3a series. The new leak suggests that the Pixel 3a will include single sensor on the back as well as on the front. On the rear panel the phone is tipped to come with a 12.2 MP sensor with dual pixel autofocus with an f/1.8 aperture – similar to what the Pixel 3 offers. On the front the Pixel 3a is expected to sport an 8MP sensor with f/2.0 aperture.The leaked specs sheet also suggests that the Pixel 3a will have Active Edge embedded into the body. This feature will allow users to launch Google Assistant just by squeezing the phone from the sides. The Pixel 3a is said to come with a USB-Power Delivery 2.0 for 18W quick charge. It will also include support for 3.5mm headphone jack, 5GHz Wi-Fi ac support, Bluetooth 5.0, and NFC.Ahead of the launch, the price of the Pixel 3a has also been leaked. The Pixel 3a is expected to have a starting price at $399. The Pixel 3a XL will be slightly expensive because of the better specs it is going to offer.ALSO READ | Dark Mode in iOS, iPad apps on macOS and more expected at Apple’s WWDC 2019ALSO READ | Google IO 2019: Expect Pixel 3a phones launch, Android Q and here is how you can watch it liveALSO READ | Google Pixel 3a, Pixel 3a XL phones to launch in India today, expect top class camera at cheaper priceGet real-time alerts and all the news on your phone with the all-new India Today app. Download from Post your comment Do You Like This Story?

The sixty-sixth United Nations Department of Public Information/Non-Governmental Organizations Conference kicked off today in Gyeongju, Republic of Korea, with Secretary-General Ban Ki-moon highlighting the vital role that NGOs, academia and youth play in achieving the Sustainable Development Goals (SDGs).“We need governments, the private sector and civil society,” Mr. Ban told the more than 2,000 people gathered for the opening session. “Without the participation of non-governmental organizations (NGOs) and civil society groups, no initiative, however visionary, can be fully achieved,” he added.From 30 May to 1 June, a series of roundtable discussions, workshops and youth caucuses with civil society representatives and groups will focus on education as an entry point towards realizing the SDGs.“Education is critical to nurture global citizens who can rise to the challenges of the 21st century,” continued Mr. Ban, encouraging young people everywhere to be global citizens and for governments and NGOs to boost the participation of and with their national youth groups.“Let us work together to foster education for global citizenship – education that empowers people to contribute to our common future,” he underscored.“NGOs are on the vanguard of international action,” asserted the UN chief, adding that “throughout history, when governments reach a stalemate, NGOs work to break it.”Recalling that just four days ago, at the Jeju Forum for Peace and Prosperity, in Seoul, he had denounced the shrinking democratic space, and urged freedom for civil society organizations, NGOs and human rights defenders, the Secretary-General noted that unfortunately, such freedom is under threat, “including at the last place this should happen: at the United Nations.”“I am deeply disappointed that the Member States on [the UN Economic and Social Council] ECOSOC NGO Committee recently denied the Committee to Protect Journalists consultative status,” he told the Conference, adding that he was also opposed to the exclusion of LGBT organizations from the upcoming High-Level Meeting on Ending AIDS. “These NGOs are close to communities affected by the epidemic and they must be part of the response,” he stated. Calling on UN Member States to stop constricting NGO engagement, the Secretary-General said: “The United Nations should have a big tent under which everybody can have […] freedom of movement.” Indeed, such an approach had helped for the landmark 2030 Agenda for Sustainable Development and the Paris Agreementon climate change. “And NGOs are crucial to their success.”“When we implement these two [accords], I am sure that by the end of this century we will be able to live, regardless of where we may live, in a much better, healthier and more prosperous world,” said Mr. Ban.Sharing the podium, Prime Minister of the Republic of Korea, Mr. Kyo-ahn Hwang reaffirmed his country’s commitment to fostering global citizenship.“We worked very hard so that global citizenship was reflected in the SDGs,” he said. “Global citizens need to fulfill the basic values of humanity. They need to be proactively involved in solving global issues. This conference, under the theme of ‘Education for Global Citizenship: Achieving the Sustainable Development Goals Together’ will encourage people to become involved.”Participants at the conference will examine the three pillars of formal education; informal education and training; and advocacy and public Information, as means to eliminate inequalities that create or perpetuate marginalization and disenfranchisement.Crosscutting themes, such as gender equality and climate change, will be tabled and learning will be examined from the perspective of marginalized and vulnerable groups, including indigenous peoples, and lesbian, gay, bisexual and transgender persons (LGBT).The event will culminate in an action agenda for NGOs and academia to harmonize and catalyze efforts for the successful implementation of the 2030 Agenda for Sustainable Development.Conference co-chairs, Dr. Scott Carlin, Associate Professor of Geography at Long Island University and Dr. YuKang Choi, NGO Representative to the U for Dream Touch for All, flagged the conference as an important opportunity to raise awareness and mobilize civil society around the SDGs.“The NGO/DPI Conference will bring the civil society voice to the United Nations, and foster NGO support for implementation of the 2030 Agenda,” said Dr. Carlin.Dr. Choi pointed out, “This is the first time the conference is being hosted in Asia,” calling it “an opportunity for NGOs in the region to tap into networks and to lobby governments for commitment to SDG implementation.”The Conference is being organized in cooperation with the NGO/DPI Executive Committee, the NGO community, the Government of the Republic of Korea and the National Organizing Committee of Korea.To watch the Conference proceedings live, visit http://outreach.un.org/ngorelations/conference. read more

first_imgMillions of kilometres of tunnels criss-cross the ground under old mining communities across the US and other countries. Abandoned, falling apart and choked with water, the tunnels are often viewed as a dangerous legacy. But the water in these mines could actually be a major geothermal resource. Student researchers at Michigan Technological University have put together the first comprehensive guidebook communities can use to explore the feasibility of using mine water for geothermal energy to heat and cool buildings. While there is great potential for this resource, there are less than 30 active mine water geothermal systems in the world. One is at Michigan Tech’s Keweenaw Research Center just north of Houghton, Michigan.The research team worked with the University’s Keweenaw Research Center and community leaders in Calumet to understand the local potential. In fact, the idea for this project came from community members in Calumet, and especially Elmore Reese at Main Street Calumet.This week, the team will present its work in Washington, D.C., for the National Sustainable Design Expo, a student design competition supported by the Environmental Protection Agency (EPA). The project is funded by a People, Prosperity and Planet (P3) grant through the EPA. The researchers will find out about a second round of funding at the expo.Michigan Tech graduate student Edward Louie spearheaded the project as part of his master’s degree work in energy policy. “With mine water, you can draw lots of heat from it without it cooling down,” Louie says, explaining that the mine water in the Keweenaw stays around 53 to 55oF year-round. These temperatures can then be used to heat or cool buildings using simple technology: mostly pipes, heat exchangers and heat pumps.“A heat pump is simply a device that can move and concentrate heat with relatively little energy input,” Louie says, adding the equipment has been around since the 1970s. “The efficiency of heat pumps has gotten better; their reliability has gotten better, but the technology itself is not from Star Trek.”Louie compares a geothermal heat pump to a refrigerator, which acts as a heat pump. The refrigerator compressor uses a little electricity to move a lot of heat, he explains. It concentrates the heat, moving it out the back, and puts the cold inside. “That’s why the back of your fridge is warm ,and that’s why your freezer is freezing cold.”In a geothermal heating system, the heat pump concentrates a relatively small amount of heat from the mine water, which remains much warmer than the winter outside air, into comfortable temperatures for heating a building. “It’s like the back of the fridge is placed in your house,” Louie says. “So, it’s dumping the heat in a warmer form into your house.”For cooling, the heat pump works in reverse, dumping cooler air into the building. And for every unit of energy used to power the heat pump to do this exchange, the pump can move four — sometimes more — units of heat.Geothermal systems are inherently flexible, depending on location and the quality of the mine water. In the Keweenaw, where pure copper was mined, the mine water is relatively clean. In other areas, mine water laden with heavy metals and acid corrodes equipment. For this reason, Louie and his team outline several open and closed loop systems in the mine water geothermal guidebook.Closed loop systems help protect equipment from corrosive mine water by exchanging heat outside a loop of corrosion resistant pipes placed inside the mineshaft. The mine water itself is never pumped. In open loop systems, the mine water is pumped and makes contact with a metal heat exchanger. The advantage is increased efficiency and less piping, but the mine water has to be clean enough.At the Keweenaw Research Center (KRC), mine water is piped up from about 100 m below surface. Through a big heat exchanger, the mine water cools or heats a closed loop system within the building.“It’s just like the radiator in your car,” says Jay Meldrum, director of the Keweenaw Research Center. “The water always stays inside the pipes and is mixed with glycol so it doesn’t freeze.”The water-glycol mix circulates and runs through 18 heat pumps throughout the center’s main building. Meldrum says he hopes to expand geothermal on the site and is planning a new, smaller system in a separate building. “We hope to use geothermal as an educational resource,” he says. “It’s also an area we want to continue doing research in.”With so few active systems, the KRC is a unique resource for people living in the region. Tapping into the mine water is also a tribute to the area’s history, says Richelle Winkler, a sociology and demography researcher at Michigan Tech who works with Louie and Meldrum.“Using the mine water for geothermal energy creates an opportunity to recast community identity,” Winkler says, “which both celebrates the mining heritage and promotes progress forward in an environmentally sustainable way.”With so much room for expansion, the Keweenaw could become a hub for mine water geothermal. And through the guidebook, Louie, Winkler and their collaborators could help shape a widespread environmental problem into a solution and resource.Picture courtesy of www.undergroundminers.comlast_img read more
