Cars that Run on Cow Power

first_img(PhysOrg.com) — Race cars have long provided a testing ground for driving technology that we eventually see in passenger cars on the road. To this end, an engineering team in Lancashire, England, is hoping to give cow power a place in mass-produced consumer automobiles by creating a race car that runs on cow manure. Yep, there are hopes that by processing cow waste and using it to fuel cars, it can reduce the impact of two things that contribute to global warming. Using cow power to win a rally championship may seem like a tall order, but these engineers are up to the challenge. Gas 2.0 offers this on the process of getting a race car to run on cow waste:The process, which has been gaining attention worldwide, uses fermented cow poop and anaerobic digesters to provide natural gas fuel. Rally racing is an intense form of motorsports that pushes car on-and-off road, and racers quickly figure out what does or doesn’t work. Oacktec has already developed hybrid-electric motors for Honda, so they plan on using a Honda Civic Hybrid to compete within a year.In the end, there are hopes that using hybrids on the race track could provide an advantage. Electric motors offer lots of torque that could send cars out of corners faster, providing an advantage of seconds — which are precious to race car drivers. Using a hybrid car that runs partially on cow manure may provide an interesting alternative to current gasoline-electric hybrids. But we’ll first have to see how cow power performs on the racetrack.© 2009 PhysOrg.com Mercedes to Produce a Fully Electric Gullwing Explore furthercenter_img Citation: Cars that Run on Cow Power?

Dyson patent shows washdry of hands from same fixture

first_img © 2012 Phys.org More information: appft.uspto.gov/netacgi/nph-Pa … 95&RS=DN/20120291195 Explore further Dyson alleges Bosch employed mole to steal secrets Citation: Dyson patent shows wash-dry of hands from same fixture (2012, December 4) retrieved 18 August 2019 from https://phys.org/news/2012-12-dyson-patent-wash-dry-fixture.htmlcenter_img Sensors play a role in this invention, releasing water to clean your hands and recognizing when you place open palms under ducts that they are ready for a blast of air for drying. The patent filing proposes a “dual-purpose fixture for a sink or wash basin, incorporating both a water tap and a hand dryer. The water tap has a spout arranged to project over the basin of the sink, and the hand dryer incorporates two or more hand-dryer nozzles—at least one for each of a user’s hands. The left-hand nozzle is located on the left-hand side of the spout and the right-hand nozzle is located on the right-hand side of the spout, specifically so that the spout acts as a dividing partition between the two hand-dryer nozzles. This encourages correct usage of the hand-dryer. The fixture may be fitted to a sink or wall-mounted above the sink.”Patent filings such as this quickly catch buzz because the Dyson name is associated with inventiveness and good engineering; James Dyson, after graduating from London’s Royal College of Art, began designing gadgets and machines with an early milestone becoming the bagless vacuum cleaner that eventually became a UK best-seller. Dyson machines are in the permanent collections of the Museum of Modern Art and London’s Victoria and Albert Museum, among other places. As for drying machinery, Dyson engineers have been brainstorming better designs and technologies for hand drying, with their Airblade hand dryer. Energy efficiency and good hygiene are some of the promotion points driving the product. Dyson engineers, according to the company, and scientists spent three years developing, testing and refining the Airblade for drying hands. They quoted a study that said that paper towels and warm air hand dryers generate 70 percent or more carbon emissions than the Dyson Airblade hand dryer. Rather than warm air, the Dyson Airblade hand dryer uses sheets of cool cleaned air to scrape water from hands. Air is forced through two apertures described as the width of an eyelash, creating sheets of air travelling at 400 mph. Water is scraped from hands in twelve seconds. (Phys.org)—Dyson, the British design and manufacturing company known for its vacuum cleaners, fans, and hand dryers, has yet another innovative cleaning design on the burner. This time Dyson has come up with the idea of providing a tap that washes and dries your hands from one and the same device. There would be no need to move away from the sink and use a hand towel if at home or to stand in line to wait for a free hand dryer at a public restroom. The idea is that a single faucet on the sink can behave as air blower and water spout for cleansing hands. Dyson, a British company, filed the patent in the U.S. on May 17.

Best of Last Week – Sun may determine lifespan superinsulated clothing and

first_img(Phys.org)—It was a good start to the New Year, particularly for space exploration. Researchers studying images taken by NASA’s Curiosity rover noted potential signs of ancient life on Mars—sedimentary rock on the Red Planet looked strikingly like structures made here on Earth by microbes. Meanwhile another team of astronomers announced that eight new planets were found in the “Goldilocks” zone—doubling the number of known small planets to exist in the habitable zone of their parent stars. Also, another team in Norway found that the Sun may determine lifespan at birth—they found a connection between the amount of solar activity occurring when people are born and how long they live. And in somewhat related news, a pair of scientists tackled the mystery of an ancient astronomical device—James Evans and Christian Carman reported on an analysis of a dial on the Antikythera Mechanism believed to have been used to calculate lunar and solar eclipses, and why they believe it sets the date for creation of the machine at around 205 B.C.

Aguilar/CfA It was a good week for technological innovation as well as. A team at Stanford outlined their work with textiles that have been dip-coated in a silver nanowire which they suggest could lead to super-insulated clothing that could eliminate the need for indoor heating. And another team in Korea announced a perovskite solar cell that reached record efficiency—they found a new formula for mixing such structures that allows for creation of cells that are on a par with those made from silicon.In unrelated news, a team of researchers has found additional evidence that rotating night shift work can be hazardous to your health—their study of female nurses showed a higher incidence from all causes of mortality for those that worked rotating shifts over long periods of time. Also, it was noted that adding a leap second this year is expected to cause Internet problems—users may want to avoid such sites as Foursquare, Reddit, Linkedln and Yelp on June 30 at midnight.And finally, if you are one of the millions of people struggling to maintain a healthy weight level, help may soon be on the way as a team of researchers has reported on their efforts to create a more effective diet pill—an “imaginary meal” compound that tricks the body into losing weight. Instead of dissolving into the blood, the pill (fexaramine) remains in the digestive tract, fooling the body into thinking it has a large meal to digest. More testing needs to be done, but so far, they report that the pill does stop weigh gain. This document is subject to copyright.

Multiple stellar populations detected in the cluster Hodge 6

first_imgCN vs CH for all member stars in Hodge 6. A spread of ∼0.7 mag in N is much larger than the negligible spread in C. Purple points indicate the enriched stars, more than 1σ from the median of the population. The blue points are non-enriched stars. Image credit: Hollyhead et al., 2019. Observations show that almost all globular clusters (GCs) exhibit star-to-star abundance variations of light elements such as helium (He), oxygen (O), nitrogen (N), carbon (C) and calcium (Na). This indicates self-enrichment in GCs and suggests that star clusters are comprised of at least two stellar populations. Recent studies have found that multiple stellar populations are also present outside GCs, including intermediate age massive star clusters (between 2 and 8 billion years old). With an age of about 2 billion years, Hodge 6, located in the Large Magellanic Cloud (LMC), is an example of such cluster. A team of astronomers led by Kathie Hollyhead of Stockholm University, Sweden, now reports that Hodge 6 also hosts at least two populations of stars.The astronomers employed VLT’s FORS2 instrument to conduct spectroscopic analysis of Hodge 6. They obtained low-resolution spectroscopy of lower red giant branch (RGB) stars in the cluster in order to look for signatures of multiple populations in CN and CH band strengths that trace nitrogen and carbon.”We report the spectroscopic discovery of abundance spreads (i.e. multiple populations) in the ≈2 Gyr old cluster in the LMC, Hodge 6. We used low-resolution VLT FORS2 spectra of 15 member stars in the cluster to measure their CN and CH band strengths at ~3883 and 4300 ̊A, respectively, as well as [C/Fe] and [N/Fe] abundances,” the researchers wrote in the paper.FORS2 spectra allowed the team to detect a sub-population of two stars enriched in nitrogen, which, according to the study, is indicative of multiple populations in Hodge 6. The researchers add that these stars showcase spread in CN, which traces nitrogen, with negligible spread in CH, which traces carbon.Furthermore, given that Hodge 6 exhibits no extended main-sequence turn-offs (eMSTOs), features commonly found in the color-magnitude diagrams of young and intermediate-age massive star clusters, the scientists suspect a possible correlation between this phenomenon and the presence of multiple populations. However, more studies are needed in order to determine whether these two phenomena are related.”The apparent coincidence of the lack of eMSTOs and the beginning of MPs [multiple populations] could well be just that—a coincidence. Relatively few clusters have been studied at this exact age limit, so there is not a statistical consensus to indicate that these two phenomena are related, though studies so far do point to an age dependence on the onset of MPs,” the paper reads.The researchers note that Hodge 6 turns out to be the second cluster with an age of around 2 billion years and that hosts multiple populations, after NGC 1978 in LMC. Their study also marks the first spectroscopic detection of multiple populations in a cluster of this age. This document is subject to copyright.

first_imgMy younger sister is mixing with the wrong kind of friends. She’s 19 and we are terribly worried. Please advise.Rajeev Shaw, NagpurJust sit down and have a discussion with her. Explain and express your concern and worry. This explanation should be more like a friend and not like a guardian. Help her understand life and help her fix her dreams. Remember, Always treat her like an adult and be a friend to her.I feel my husband is into a relationship. I asked him many times, but he has pointedly refused. I’m not convinced but don’t know how to find the truth. Also Read – ‘Playing Jojo was emotionally exhausting’Name withheld, New DelhiIt’s quite natural that if your husband is guilty he will not own up. You have two options. One, don’t stop asking questions till he tells the truth. Second, hire a private investigation company who would charge you a sum and would hand over the complete day-to-day schedule of your partner along with relevant photographs and evidence. I suggest, don’t linger in this shadow of suspicion for too long. Decide and delve into the situation tofind the solution. Once you have enough proof, face him and sort it out soon. All the best!

Unraveling art and history

first_imgBe ready to be walk through the walls of Indian history this Summer as the Pran Sabharwal Foundation (PSF) is organizing an exhibition displaying around 300 artworks on lithographs, wood engravings, steel plate engravings and other canvases, from colonial Indian times by artists such as William and Thomas Daniell, Solvyn, Mortimer Menpes and Dottor Ferrario at 1AQ on Mehrauli Road in the Capital from April 25 to May 17.The Foundation, which strives to utilize art as a medium to highlight social issues, has yet again brought forth an exhibition capturing the close ties that art, history, culture and tradition. It will certainly be difficult to find out if man’s quest for great art helped in digging out history or if man’s interest in knowing his past helped in discovering great art. Since time immemorial, art and history have been woven together like silk and gold, coexisting and bringing beauty and meaning to one another.   Also Read – ‘Playing Jojo was emotionally exhausting’Works of art till date help in understanding the culture and lives of people of the time that they originate from and what we know of history helps us understand the significance of a particular piece of art, based on its times.William and Thomas Daniell, Solvyn, Mortimer Menpes, Dottor Ferrario and many other artists accurately captured various Indian elements such as monuments, gods and goddesses, ways of worship, their observations of traditions and culture, glimpses from daily colonial life, various flora and fauna, starting from early nineteenth century, on lithographs, hand-colored lithographs, wood engravings and steel plate engravings. Also Read – Leslie doing new comedy special with NetflixIt is interesting to note that the tradition and culture of India depicted in these works of art, more or less remain the same even after about 200 years. The monuments that are seen in these works are also very close to the original monuments that are present till date, telling us volumes about the effort that has gone into preserving them over a couple of centuries or even more.These works, which were mainly done by British artists, represent India from a colonial point of view. The work of the common  people, or a day-to-day setting depicts the colony that India was all those years ago and it helps in understanding the traditions colonialism has given birth to and how they’ve been carried forward. Through its dedication to promote art and highlight issues, Pran Sabharwal Foundation, is making a change in the lives of the underprivileged and disadvantaged- specially women. It had earlier hosted a play Ji Jaisi Aapki Marzi, by Nadira Babbar, which focused on the plight of women in India. The play covered issues such as female foeticide, discrimination and gender inequality. PSF also partnered with National Commission for Women (NCW) and Amar Ujala Foundation to host the first-ever national symposium on empowerment of acid attack survivors, inaugurated by the Home Minister of India Rajnath Singh, in February 2015.There could not have be a better place to organize this prestigious exhibition of art, history and culture than Delhi’s very own creatively inspiring space 1AQ.
