(PhysOrg.com) — Concrete accounts for about 5% of all human-related CO2 emissions. The fact that we use so much cement in building could mean that the issue becomes even more pronounced in the future. But what if there was a way to make concrete that was more environmentally friendly? A team of researchers in Texas things there might be — by adding rice to concrete.

By mixing rice husk ash into the cement, there is the possibility of greener concrete. Discovery News offers this on the process of creating carbon neutral rice ash:Now, Rajan Vempati of ChK Group, Inc. in Plano, Texas, and a team of researchers have figured out a way to make nearly carbon-free rice husk ash. Heating husks to 800 degrees centigrade (1,472 degrees Fahrenheit) in a furnace drives off carbon, leaving fine particles of nearly pure silica behind.”The process emits some CO2, but it’s carbon neutral. Any that we emit goes back annually into the rice paddies,” Vempati said.Concrete is a favorite repository of unwanted waste materials, from steel slag to silica fume, since it can provide a useful way of recycling products that are hard to get rid of without filling landfills. Ash from rice husks, while not completely neutralizing the pollution that comes from making cement, could reduce it. On top of that, this ash provides protection against corrosion and strengthens the concrete.The process has yet to be refined and tested in real-world conditions, so the idea is still mostly in its initial stages. However, when one considers that up and coming economic powers, such as India and (especially) China, will be likely ramping up production of concrete for use in buildings and roads, the prospect of reducing carbon emissions and pollution through the use of risk husk ash in concrete becomes even more interesting.© 2009 PhysOrg.com This document is subject to copyright.

The system takes a string of words, in Japanese obviously, and converts them into the gestures that make up sign language. The goal of the project is to create more effective sign language broadcasts for deaf television viewers. The system could be used to allow for more effective communications in the event of a state of emergency or important breaking news, though it does have the potential to be used in entertainment capacity as well. While there is a current form of communication in place, subtitles, they are not always an effective way of communicating with those who were born deaf, as research has shown that they may have more difficulty understanding the subtitles than they would seeing the message signed. This system can enhance the level of comprehension in the event of a disaster.The system takes the text, and translates it to signing. The system can also convert the existing words directly to signing and replacing the words that do not have a direct translation with a synonym in order to get the word across. The system then shows the signing done by a virtual avatar that is dressed like a reporter. Current testing of the system shows that the hearing impaired were able to get a basic message from the system, through the whole message may not be a fluid as a live translator would be in the same situation. The system will still have a built-in manual system where a human can go in and fix the translations for enhanced accuracy.

The present study aims to decipher ephemeral channel networks, which are common landscape features in the surroundings of the necropolis, from landforms that were subject to human influence. The analysis was carried out on the basis of surface geometry as derived from a digital elevation model (DEM). The hypothesis is tested that the natural fractal patterns of channel networks lead to fractal surface topography, when fluvial processes are the main factors for relief evolution. Therefore, the estimated fractal dimension of channel networks is correlated with the fractal dimension of surface topography to determine the mutual functional relationship. A high degree of functional relationship within some areas of the DEM shows that channel networks are self-similar branching trees that imprint their geometry on to surface topography in a scale range of ∼15 to ∼190 m. A low correlation of fractal patterns of channel network and surface topography in the vicinity of the pyramid district of the necropolis is interpreted as channel beds modified or induced by human impact, either due to the usage of the channel beds as transport ways for building material leading to an acceleration of processes like soil erosion or due to direct activities like mining or landscape architecture.via Newscientist (Phys.org) — A team of Earth scientists from Germany has turned to fractal pattern recognition analysis to study a part of the ground that makes up a river delta, and has found evidence of pyramid building practice by the father of the man believed to be responsible for building the Great Pyramid of Giza.

Egypt to open inner chambers of ‘bent’ pyramid Explore further © 2012 Phys.org Citation: Earth scientists use fractal analysis to uncover ancient Egyptian pyramid practice site (2012, July 23) retrieved 18 August 2019 from https://phys.org/news/2012-07-earth-scientists-fractal-analysis-uncover.html Fractals are natural or artificially created geometric patterns that form designs that appear to repeat themselves when magnified, over and over again. In nature, deltas created where rivers meet the ocean quite often display fractal properties, and because of this, the research team used fractal analysis to determine the extent of the Dahshur royal necropolis near Cairo, a site believed to have been used by King Sneferu to develop pyramid building skills. Sneferu’s son, Khufu, is believed to be responsible for building the Great Pyramid of Giza, one of the great man-made wonders of the world.Since the time of Sneferu, some 4500 years ago, nature has worked to wash away virtually all evidence of human endeavors, and in fact, surveying the region with the naked eye reveals very little evidence of the ancient Egyptians activities. It was for this reason that the team turned to fractals. Their reasoning was that man made changes to the landscape would differ from natural fractal patterns as seen from far above, and that those changes would take significantly longer to wash away. And that’s exactly what the team found. After taking pictures of the site from an airplane and then running them through digital fractal analysis, they found distinct differences between land that developed naturally and land that was disturbed by the ancient civilization still learning how to build the monuments that have become their legacy.The team was surprised to learn of the large area size involved – six square kilometers that differ so markedly from the surrounding terrain after digital alterations, that the early plain is clearly visible. So clear were the images produced, the researchers were able to discern some geographical properties of the land, which they identified as broad terraces that they surmise were used to increase the impressiveness of the pyramids themselves.Because the effort proved largely successful, it’s likely other teams will employ it as well on other land areas, possibly uncovering other features that have until now, remained hidden in plain sight.

DOI: 10.1016/j.enconman.2016.06.007 (Phys.org)—Last year, researchers at George Washington University proposed a method for transforming CO2 emissions into carbon nanotubes (CNTs). When applied to power plants, the technology could completely eliminate the power plants’ CO2 emissions while simultaneously producing a valuable product that is used for a variety of applications, including batteries, consumer electronics, airplanes, and athletic equipment. Citation: Researchers assess power plants that convert all of their CO2 emissions into carbon nanotubes (2016, June 20) retrieved 18 August 2019 from https://phys.org/news/2016-06-power-co2-emissions-carbon-nanotubes.html In other words, the small decrease in power output is more than compensated for by the highly valuable carbon nanofibers and nanotubes that could be produced. This is mainly because industrial-grade carbon nanotubes are such an expensive commodity, which currently cost about $300,000/ton ($130/pound) to produce using methods available today. Using the new method, the researchers estimate that it would cost just $2,000/ton to produce CNTs—less than 1% of current production costs. The researchers hope that this large profit potential will make the technology seem like an obvious choice. Since CNTs are about 10,000 times more valuable than carbon tax credits (which are roughly $30/ton), the researchers predict that CNT production will offer a greater incentive for the energy industry to reduce carbon emissions than carbon tax credits offer. Even though the value of CNTs would likely decrease in the future since they can be produced much more easily and cheaply using this new method, that would simply spread part of the economic benefit to other industries. Lower CNT prices would spur CNT market growth and positively impact the many industries that use them, including the automobile, airline, and wind turbine industries.The researchers’ assessment also shows that the CC CNF plants make sense from a thermodynamic perspective when compared to conventional CC plants with and without carbon sequestration, as well as conventional coal plants. Even though the CC CNF plants would produce somewhat less electricity than the other types of plants, they would do so at a higher efficiency. The improved efficiency is due to heat energy gained in several areas that could be recycled back into the steam turbines. The heat energy comes, for instance, from the energy produced from chemical reactions with lithium oxide; the energy gained from cooling the carbon and oxygen products; the energy gained from burning the natural gas with a mix of pure oxygen and air (splitting the CO2 releases pure oxygen as well CNTs); the energy saved from preventing CO2 emissions; and the energy gained by capturing CO2 at a much higher temperature than the temperatures at which CC plants with carbon sequestration operate. And unlike carbon capture technologies, energy is not need to store the CO2 as a waste material, since instead it is converted to a valuable product. Currently, the researchers are working to build and implement the technology as quickly as possible.”We are quickly scaling up the process, which is the challenge to rapid deployment and substantial CO2 reduction,” Licht said. CO2, captured either directly from the atmosphere or from a combined cycle (CC) natural gas power plant, can be electrolyzed to produce oxygen gas and carbon nanofibers, which can then be used to make a variety of valuable products. Credit: Lau et al. ©2016 Elsevier Ltd Explore further ExxonMobil launches venture for low-cost carbon capture © 2016 Phys.org The technology can work with almost any kind of power plant, but the researchers specifically investigated its application for combined cycle (CC) natural gas power plants, which are the most efficient kind of electrical power plant yet still emit massive amounts of CO2. The idea is to add a molten lithium carbonate electrolyzer to a conventional CC plant, creating a CC carbon nanofiber (CC CNF) plant. Using electrolysis—the same technology that splits water to produce hydrogen—the system applies a voltage to split CO2 into oxygen gas and solid carbon nanofibers. Adding in small quantities of nickel causes the carbon nanofibers to be hollow, forming CNTs.To make sure that the idea isn’t too good to be true, in a new study the same researchers have performed a thermodynamic assessment of the proposed CC CNF plant. They found that the concept is economically feasible and even improves the power plants’ energy efficiency. “The technology incentivizes carbon dioxide removal by transforming this greenhouse gas into a valuable product to ameliorate the impact of climate change,” Stuart Licht, a chemistry professor at George Washington University and leader of the study, told Phys.org. “The production of CNTs will actually be more profitable for fossils fuel power plants than making power, and this should incentivize the transition to a renewable, sustainable society. CNTs have over twenty times the strength of steel or aluminum and are lower weight, and we hope that the CNTs will provide a complete replacement for the trillion-dollar steel and aluminum market. CNTs are also useful in nanoelectronics and new medicine delivery systems, and are already being used in textiles [such as bullet-proof clothing].”The researchers’ assessment shows that, for every metric ton of methane fuel consumed, a conventional CC power plant produces $909 of electricity and emits 2.74 tons of CO2. In contrast, the proposed CC CNF plant would produce about $835 of electricity, which is about 8% less than the CC plant. But the CC CNF plant would also produce about 0.75 tons of CNTs, which is worth an estimated $225,000, and emits no CO2. This document is subject to copyright.

(Phys.org)—A pair of researchers with the Physical Research Laboratory in India studying data sent back from NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) probe has found possible evidence of the development of rings around the planet. In their paper published in the journal Icarus, Jayesh Pabari and P. J. Bhalodi describe the data, what the probe has measured, and the likelihood that some of the dust that surrounds Mars may one day accumulate into a set of rings encircling the planet. © 2017 Phys.org Scientists have speculated for many years that one day (20 to 70 million years from now), Mars will have rings around its equator similar to those seen around Saturn today—this is because the material that makes up its two biggest moons is unstable and likely to result in the moons tearing apart as they are drawn closer to the planet by its gravity. But now, it appears that the process might already have begun. In this new effort, the researchers found evidence in data from MAVEN that suggests at least some of the dust encircling the planet came from one or both of its biggest moons, Phobos and Deimos.Data from MAVEN had already shown that there was a cloud of dust surrounding Mars, but it is still not clear how big the particles are. Space scientists believe that most of the dust that is thrown into the atmosphere when the planet and its moons are struck by asteroids is composed of particles so tiny that they are carried away by the solar wind. The new analysis by Pabari and Bhalodi, which compared dust and rock particles found in the Martian upper atmosphere with those predicted by models, showed that most of the dust in the cloud was interplanetary. But there was also a small component (approximately 0.6 percent) that appeared likely to have come from one of the two moons.The researchers are quick to point out that spotting moon particles in an outer atmospheric cloud is not evidence of proto-ring development, but suggest it is possible. They note it will not be possible to determine if such activity is truly occurring until a probe is sent to Mars that is capable of fully analyzing material in the dust cloud.

DOI: 10.1016/j.icarus.2017.01.023AbstractRecently, MAVEN observed dust around Mars from ∼150 km to ∼1000 km and it is a puzzling question to the space scientists about the presence of dust at orbital altitudes and about its source.A continuous supply of dust from various sources could cause existence of dust around Mars and it is expected that the dust could mainly be from either the interplanetary source or the Phobos/Deimos. We have studied incident projectiles or micrometeorites at Mars using the existing model, in this article. Comparison of results with the MAVEN results gives a new value of the population index S, which is reported here. The index S has been referred in a power law model used to describe the number of impacting particles on Mars.In addition, the secondary ejecta from natural satellites of Mars can cause a dust ring or torus around Mars and remain present for its lifetime. The dust particles whose paths are altered by the solar wind over its lifetime, could present a second plausible source of dust around Mars. We have investigated escaping particles from natural satellites of Mars and compared with the interplanetary dust flux estimation. It has been found that flux rate at Mars is dominated (∼2 orders of magnitude higher) by interplanetary particles in comparison with the satellite originated dust. It is inferred that the dust at high altitudes of Mars could be interplanetary in nature and our expectation is in agreement with the MAVEN observation. As a corollary, the mass loss from Martian natural satellites is computed based on the surface erosion by incident projectiles.
John W. Poole by NPR News Selena Simmons-Duffin 8.23.19 1:08pm Lost in all the brouhaha about President Trump’s scuttled plan to buy Greenland from Denmark has been this: What do the Greenlandic people think about the whole thing?In the small capital city of Nuuk, “everybody is talking about it,” says Alexander Montgomery-Andersen, a 30-year-old Greenlandic dancer and choreographer. “It’s a little comical.”Greenlander Lasse Norregaard suggested on Facebook that Trump trade Hawaii to Greenland in exchange “for an area of the same approximate size on the Greenland ice cap.” The area, he said, “will be the perfect geopolitical stronghold for you to do whatever you wish.” Others joked that maybe all this talk would improve tourism, which is a fairly young industry.But many Greenlanders were angered and upset by Trump’s comments, which they consider a threat to their sovereignty and human rights.”It’s dead serious for Greenland,” says Aqqaluk Lynge, a former president of the Inuit Circumpolar Council.”To talk about buying a whole nation and the people is, I think, extremely imperialistic and should not be something that we hear world leaders say in 2019,” says Sara Olsvig, a former Greenlandic politician who now works in human rights. “It shows that we are still living in a world where indigenous peoples, or self-governing nations even within states, are seen as something that can be bought and sold.”The relationship between Greenland and Denmark is long and complicated. While Greenland was once a colony, it hasn’t been one for decades. The prime minister of Denmark, Mette Frederiksen, visited Nuuk last weekend and told reporters, “Greenland is not Danish. Greenland is Greenlandic.”So what is Greenland’s political status? It is a bit complicated. Today, Greenland is still part of the Danish Kingdom — but it is not owned by Denmark, and it is not a Danish colony. Greenland has its own parliament and government — though some issues, like defense and security, are handled in Copenhagen. In recent decades, there’s been a move by Greenlanders toward autonomy and, perhaps ultimately, full independence.Currently the island’s population is only 58,000 people though the country is enormous — three times the size of Texas. Most Greenlanders have indigenous roots. “The history of Inuit people in Greenland goes 4,500 years back,” Olsvig explains. “Our people — the Inuit people — have been living in the Arctic, moving back and forth across the Arctic between Russia and Greenland, for many, many thousands of years.”Over those thousands of years, Inuit people hunted and fished in the harsh, icy environment — around 80% of the island is covered by a gigantic ice sheet. “Traditionally, Inuit people are a nomadic people — we would travel to wherever we could hunt and live different places on the land during summer and during winter,” she says.Some of the first qallunaaq, or white people, to arrive in Greenland were the Vikings around 980. “That was Erik the Red, and he was the guy who named Greenland ‘Greenland.’ ” Olsvig adds, “South Greenland is quite green, actually, but if you look at the world map you will see that Greenland is quite white because we have the ice cap.”The Viking settlers apparently didn’t make it through the little ice age that began in the 1300s. “In 1721, a Christian missionary from Norway came to Greenland, and he didn’t find any of the Norse people, but he found Inuit,” Olsvig says. His name was Hans Egede — at the time, Norway was part of the Danish Kingdom. “That, we see as the beginning of the colonization.”After the missionaries started to arrive, Greenlanders began to settle in towns and give up the nomadic life. Danish and Greenlandic people have intermarried over generations — many people who identify as indigenous Greenlandic people have Danish names; many also have blue eyes. Around 95% of Greenlanders are Protestant, although many people also practice spiritual rituals that predate the Nordic missionaries.”In spite of colonization, we kept our language and many of our traditions,” Olsvig says. School instruction is in Kalaallisut or Greenlandic, there’s a national Greenlandic radio station, and newspapers are written in Greenlandic as well as Danish. There’s even a Greenlandic translation of Harry Potter. Olsvig does say some cultural traditions, like throat singing and drum dancing, which have endured among the Inuit in Canada and Alaska, were lost for a long time in Greenland, though they are starting to make a comeback.So what is life like in Greenland now? Montgomery-Andersen’s mother is American, and he spent his sophomore year of high school in Austin, Texas, so he’s had plenty of experience explaining to clueless Americans what life is like in Greenland. “I tricked people a lot,” he laughs. “I would say ‘Sure, we have polar bears and seals as pets,’ ” or “‘Yes, we live in igloos!’ ” (In fact, Greenlanders live in houses and apartments.)Greenlanders interviewed for this story credit the Scandinavian relationship for their democratic system of government and the provision of free education and free health care. High-speed Internet is available, Montgomery-Andersen says, even in a tiny, isolated town of 300 people that he visited.There are challenges to living in a country that is so huge and covered in so much ice. The only inhabitable parts are out on the edges, mostly in the south, furthest from the Arctic Circle. “Because each town is far from each other and there’s so few people in each town, there’s no roads or train tracks,” Montgomery-Andersen says. “You can’t take a bus from one town to another; you have to sail by boat or take an airplane, which makes each place very isolated.”The Greenlandic relationship with Denmark has been mostly peaceful, though not without pain and conflict. As NPR’s Rebecca Hersher has reported, Denmark has shut down small isolated towns, moving people into bigger towns, which mental health experts say has contributed to Greenland’s extremely high suicide rate. Olsvig also points out that Denmark would classify Greenlandic children as “legally fatherless” if they were born out of wedlock until as recently as 2014. “We still see the consequences of having been colonized.”The colonial status of Greenland lasted from the 1700s until after World War II, when its political standing began to change. In 1979, Greenland voted in a referendum for Home Rule, which led to the establishment of Greenland’s parliament. Then in 2009, the “Act on Greenland Self-Government” went into effect, which gives Greenland the right to hold a vote on declaring independence from Denmark. “With the self-government agreement with Denmark, all people that live in Greenland are recognized as a people pursuant to international law,” Olsvig says. “We are also part of an indigenous people, and we live with these two different political categories today.”This complex history is what President Trump waded into when he said he wanted to buy Greenland from Denmark.”I hope from all of the attention that this has been given, more world leaders will learn about the rights of indigenous peoples and of all of the many different kinds of political constructions we have in the world, where people actually have the right to self-determination,” Olsvig says. She believes that would be one good thing to come out of “all this fuss.”Copyright 2019 NPR. To see more, visit NPR. What Do Greenlanders Think Of Trump’s Interest In…
