I am sure that, through this, persons will now become more familiar with the work taking place.   A lot of times we do presentations, go to meetings and do the administrative part of it, but this is to actually get an appreciation of what is happening,” he said in an interview with JIS News.Wigton Windfarm Ltd, the largest wind energy facility in the English-speaking Caribbean, is located in Rose Hill, Manchester, and currently comprises three plants – the 20.7-megawatt Wigton I, which began operating in 2004; Wigton II, an 18-megawatt extension facility that was commissioned in 2010; and Wigton III, the 24-megawatt expansion, commissioned in 2016.    C-CAM, located in Salt River, Clarendon, was established in 1997 to promote coastal conservation in Jamaica.The tour will feature a resource centre developed in 2015, which includes a library and teaching area for persons interested in learning about the environment, Jamaica’s endemic species and national adaptation and conservation efforts.Mr. Alcock said budgeting officers from the Ministry’s Finance Department will also be included in the tour to help foster a greater appreciation for the work being done, in order to more adequately treat with certain accounting items relating to the environment.The tour will include presentations and discussions outlining the effectiveness and achievements of the facilities and how they contribute to conservation of the environment.   This is a follow-up to a recent workshop by the CCD with budgeting officers of the ministries, departments and agencies aimed at highlighting the importance of including climate change-related matters in their budgets and clearly identifying instances where it is included.Upcoming study tours will include a visit to WRB Energy, a solar farm facility in Content, Clarendon, as well as one of the country’s hydroelectric power plants.last_img read more

Volkswagen will let other companies use its MEB electriccar platform

Buggy is the electric dune buggy of our dreams Tags Electric Cars Car Industry 2020 BMW M340i review: A dash of M makes everything better See All reading • Volkswagen will let other companies use its MEB electric-car platform Enlarge ImageVW says that MEB would be ideal for low-volume specialty vehicles. Volkswagen Volkswagen’s plan to offer a wide range of electric cars — one the company has affectionately called a rollout of “electric cars for millions, not millionaires” — is all based around its new MEB modular EV chassis. At the Geneva Motor Show, VW announced it’ll open things up and let other companies use MEB to make their own EVs, too.The decision serves two purposes for Volkswagen. First, by selling more MEB chassis kits, it can amortize the cost of developing the new battery-electric technology. Second, it furthers the automaker’s stated goal of encouraging electric mobility in the fight against emissions.”The MEB is to establish itself as the standard for e-mobility. Based on the MEB, we will make individual mobility CO2-neutral, safe, comfortable and accessible to as many people as possible,” Herbert Deiss, Volkswagen AG CEO, said in a statement.The first such partner is Aachen, Germany-based e.Go Mobile, which will use MEB to make a new electric car. Neither company has said what the vehicle will be, but Volkswagen says that MEB is flexible enough that it can be used for small-volume, unconventional vehicles. Perhaps the best example of that is the I.D. Buggy concept shown at Geneva: Like the original Meyers Manx, VW hints the I.D. Buggy’s body could easily be separated from its mechanical chassis. Best of all, VW may even build an electric buggy inspired by the concept.Volkswagen says it expects a “first wave” of 15 million vehicles to be built on the MEB platform. That’ll include the I.D. family models under the VW brand as well as potential models from other brands, like Seat, Skoda and Audi.

Comcast is making an inhome health monitoring device

first_img Comcast Share your voice Comcast is working on a health tracking device. SOPA Images/Getty Images Comcast is developing an in-home health monitoring device.The company has been working on the product for over a year, according to a Tuesday CNBC report, and plans to start doing pilot tests later this year. A company representative confirmed the report and said there’s no role for the device beyond health.The device will use ambient sensors to monitor basic health metrics, and will be geared toward tracking whether someone goes to the bathroom too often or stays in bed longer than usual, according to CNBC. Comcast is also developing tools that can detect falls, according to the report.The company will reportedly offer the monitoring device to at-risk people such as seniors and people with disabilities, but there isn’t yet a set price or confirmed timing for the release. Pilots will start by the end of the year, and the device could be released commercially in 2020, the report says. The device will reportedly have a personality similar to that of Amazon’s Alexa and will make emergency calls, but it won’t be marketed as an assistant tool or carry out functions like web searches or turning off the lights. The Comcast representative emphasized that the device is built to be a sensor that detects motion, and is not a smart speaker.Comcast has reportedly been working with a handful of hospitals, including Rush in Chicago, to discuss using the device to keep patients from returning to the hospital after being discharged. Other major tech companies have also been eyeing the senior market. Nest is reportedly exploring integrating smart home devices into senior living facilities, Amazon is reportedly looking into making tech for older people and Apple added an FDA-cleared EKG feature in its Series 4 Watch that warns wearers about abnormal heart rhythms linked to atrial fibrillation.Originally published May 21, 2:37 p.m.Update, 3:07 p.m.: Adds confirmation from Comcast.

Nano this Nano that what the

first_imgMany of the processes we depend on, indeed, life itself, occur on the nanoscale. With the advent of nanotechnology, medical science has the potential ability to manipulate cells at the lowest level. Where they now use sledgehammer treatments – chemotherapy, for example, one day they may have a pair of needle-nosed pliers that could repair cells instead of just killing off the defective ones. As this article is being written, doctors are already using nanotech if the form of contrast agents for MRI scans. Gadolinium in DNA-sized carbon tubes boosts performance and reduces the metal’s high toxicity by containing the contrast agent and keeping it from affecting surrounding tissues.Not all nanotech is based on carbon atoms and molecules. A new inorganic fullerene-like nanostructure – IF for short – is a material produced by the Weizmann Group. Instead of carbon, it’s made of tungsten disulfide. Unlike carbon based organic Fullerenes, IF is easier and less expensive to produce, is chemically stable, less reactive and less flammable. Organic Fullerenes are highly toxic while IF materials have been fully tested and deemed safe. One of the most interesting new IF properties discovered is its extremely high degree of shock absorbing ability. The new Tungsten-based IF material has up to twice the strength of the best impact resistant materials currently used in protective armor such as boron carbide and silicon carbide. It’s over 5 times stronger than steel. Mixing IF with elastic materials could lead to new compounds which are both shock absorbing and flexible – perfect for ballistic armor.Another important area for nanotechnology is coatings. New nanocoated metals have high wear resistance and resilience, better thermal shock resistance, resist fatigue, and have enhanced anti-microbial activity.The list of potential uses is almost endless: In sports to make stiffer tennis racquets and sharper, more resistant snowboard edges, in lightweight nanometal foam helmets that provide up to 7 times the protection of conventional models. In medicine: nanocrystaline metals of silver and cobalt are effective antibacterial agents and can be used in air-conditioning systems to stop formation of bacterial slime. Nanocrystalline zinc oxide is used in sunscreens – zinc oxide and titanium oxide effectively absorb ultraviolet radiation. Industrial applications include: better lead acid batteries, a replacement for chrome, super lightweight parts and wear resistant coatings.Fabricators produce nanocrystalline metals – alloys and composites – using a patented electrosynthesis process. They are able to make crystal sizes 1000-times smaller than those found in normal materials. Nano has officially become the most misused word in the English language. Everything from the Ipod Nano to anything smaller than a Mac truck gets “nanoed” by clueless – or savvy, take your pick – marketing experts. It’s crept into everyday use as well: “I’ll be there in a nano.” Sure you will. For the scientists who work with nanotech this must be frustrating indeed. A definition of nano is definitely in order. Nano is 10 to the power of -9. How small is that? A nanometer is one billionth of a meter. Small, indeed – in fact, so small it’s difficult to compare it to anything, only adding frustration to the roll of scientists trying to explain nanotechnology in laymen’s terms.Let’s try anyway. A nanometer is 100,000 times smaller than the diameter of a human hair. There are as many nanometers in an inch as there are inches in 400 miles (25,344,000). About 3 to 6 atoms can fit inside a nanometer – depending on the atom size. Even when you see the comparisons, they mean nothing – it’s just too small – hence the attempt to make sense of it by tagging everything smaller than normal as “nano”.Nanotechnology is more than just a hot theoretical topic now. Computer chips are now made using a 15 nanometer lithography process. But how can something so small be useful? After all, you can’t even see it under most microscopes. The answer lies in large numbers. A Pentium 4 Extreme Edition, for example, has 178 million transistors, all on the nanoscale – defined as smaller than 100 nanometers in length. This minuscule size allows processors to be faster, generate less heat and run using less energy. At this scale, a material’s properties change—things like electrical conductivity and mechanical strength are not the same as they are at micro size. With the recently developed atomic force microscope, nanoscientists have begun to manipulate matter on an atomic level to take advantage of these exciting new properties.Their first attempts were childish – IBM made its name out of individual atoms, for example. But now nanotechnology is getting serious.Consider the carbon at the nanoscale. Arrange carbon atoms one way you get a diamond – arranged another way, you get graphite. Nanoscientists have learned to arrange carbon atoms in a new way: tiny tubes about two nanometers in width that can look like chicken wire and can grow to a length many times their diameter. It’s still the element carbon, but the carbon nanotube is a completely different material from either diamond or graphite – unlike any found in nature. These tubes may some day be the ultimate carbon fibers – theoretically, they are immensely strong. Explore further For scientists and engineers interested in exploring the properties of nanometals, they can be purchased on the Internet – get the research funding first because a 0.008” x 3” x 3” sample plate can set you back $2,000. Depending on the plate’s size and materials used, samples can cost as little as $115, however.Nanomachines are not just on the drawing board anymore, a few working models– like the gears above – are regularly produced. Integrating them into useful systems is still a ways off, but the potential benefits are staggering.Imagine submicroscopic machines that rove about the body and scrape plaque deposits from your artery walls, repair damage caused by trauma and attack cancer cells. Now that biotech is taking off as well, it should be interesting to see which approach – biotech or nanotech – offers the most benefit to medical science. In the end it may be a combination. Already a new field – Synthetic Biology – is exploring ways of duplicating biological processes with nanostructures. Some futurists predict the advent of self-replicating nanomachines. These nanobots will be able to build copies of themselves and perform some useful service to humanity – or not. No discussion of nanotechnology can leave out the famous “grey goo” that represents trillions of self-replicating nanobots that literally eat the Earth to make more copies of themselves. While this science fiction plot is not probable, it should be studied carefully before unleashing a horde of hungry nanocreatures into the wild.Closer to the truth are potential toxicity problems with fine nanomaterials. It’s not like you can filter them from the air – they are too small. Once escaped from the laboratory, they could become the Lilliputian Frankenstein of the future – forever blowing about in the wind forever changing anything they touch – like CFCs of steroids. All technologies have their problems and experts agree nanotechnology will be no exception.But with all the money flowing into nanotech research, safety concerns will like as not be pushed aside to advancement science – much as they have in the past. At what price progress? With all the potential benefits nanotechnology has to offer, it’s sure to be a bargain.by Philip Dunn, Copyright 2006 PhysOrg.com Nanotechnology is not new. In fact, for over a century, chemists have developed the ability to arrange small numbers of atoms inside molecules – at a scale of less than 1.5 nanometers – leading to revolutions in drug design, plastics, and other areas.

Astronomers discover a highly inflated subSaturn extrasolar planet

first_img More information: KELT-11b: A Highly Inflated Sub-Saturn Exoplanet Transiting the V=8 Subgiant HD 93396, arXiv:1607.01755 [astro-ph.EP] arxiv.org/abs/1607.01755AbstractWe report the discovery of a transiting exoplanet, KELT-11b, orbiting the bright (V=8.0) subgiant HD 93396. A global analysis of the system shows that the host star is an evolved subgiant star with Teff=5370±51 K, M∗=1.438+0.061−0.052M⊙, R∗=2.72+0.21−0.17R⊙, log g∗=3.727+0.040−0.046, and [Fe/H]=0.180±0.075. The planet is a low-mass gas giant in a P=4.736529±0.00006 day orbit, with MP=0.195±0.018MJ, RP=1.37+0.15−0.12RJ, ρP=0.093+0.028−0.024 g cm−3, surface gravity log gP=2.407+0.080−0.086, and equilibrium temperature Teq=1712+51−46 K. KELT-11 is the brightest known transiting exoplanet host in the southern hemisphere by more than a magnitude, and is the 6th brightest transit host to date. The planet is one of the most inflated planets known, with an exceptionally large atmospheric scale height (2763 km), and an associated size of the expected atmospheric transmission signal of 5.6%. These attributes make the KELT-11 system a valuable target for follow-up and atmospheric characterization, and it promises to become one of the benchmark systems for the study of inflated exoplanets. (Phys.org)—An international team of astronomers led by Joshua Pepper of the Lehigh University in Bethlehem, Pennsylvania, has detected an extremely inflated sub-Saturn exoplanet orbiting a bright subgiant star. The newly discovered alien world is one of the most inflated, least dense planets known to date. The findings were presented in a paper published July 6 on arXiv.org. Palomar AO image of KELT-11. The four spots oriented cardinally with the target are a result of the alignment procedure and are not astrophysical. Credit: Pepper et al., 2016. Citation: Astronomers discover a highly inflated sub-Saturn extrasolar planet (2016, July 13) retrieved 18 August 2019 from https://phys.org/news/2016-07-astronomers-highly-inflated-sub-saturn-extrasolar.html © 2016 Phys.org Explore further The team used the Kilodegree Extremely Little Telescope (KELT) to observe a bright subgiant star named HD 93396 (KELT-11), which is located some 320 light years away. They were looking for transit signals indicating the presence of a planet circling this distant star. KELT was chosen for this job as it can observe stars generally brighter than those observed by other ground-based surveys.”KELT is important specifically for the discovery of transiting giant planets orbiting bright stars. These are the best targets for developing the tools for measuring the atmospheric properties of planets. While KELT is not discovering large numbers of planets compared to other surveys, our discoveries are individually very valuable,” Pepper told Phys.org.KELT consists of two robotic telescopes, KELT-North and KELT-South, that are conducting a survey for transiting exoplanets. KELT-North is located in Arizona, while KELT-South is situated in South Africa.The transit signal detected by KELT was very weak and very long, lasting almost seven hours, due to the fact that HD 93396 is a subgiant. For these reasons, it was difficult for the researchers to get the whole transit in one night.”This discovery was very challenging. The original KELT observations of the star – its light curve – showed only a hint of the transit, just slightly above the threshold that led us to selected for follow-up. Because the transit is both shallow (a little under 0.3 percent change in brightness) and long, it was very difficult to obtain reliable, complete confirmation observations,” Pepper revealed.To confirm the planetary status of the detected object and obtain its characteristics, the team carried out follow-up observations employing a set of other telescopes worldwide.The planet, designated KELT-11b is a low-mass gas giant, larger in size than Jupiter with a radius of about 1.37 Jupiter radii, but having only approximately 20 percent of Jupiter’s mass. This makes KELT-11b the third-lowest density planet ever discovered with a precisely measured mass and radius.The newly discovered planet is also described by the researchers as extraordinarily inflated, due to the fact that its radius is much larger than expected. According to the study, its radius is about twice as large as predicted by the mass-radius-incident flux relation. However, as the cause of the inflation process is still being debated, KELT-11b could provide some answers on the nature of this mechanism.”We think that KELT-11b will be a great test case to help us understand the mechanism that causes inflated planets. It will also be a valuable target for developing the techniques for probing exoplanet atmospheres as we prepare for the capabilities of the James Webb Space Telescope. Furthermore, since the host star has evolved onto the subgiant branch and is reaching the end of its life, we hope that we can study the behavior of planetary systems at the end-stage of their star’s lifetime,” Pepper concluded.Pepper and his team plan further studies of this planet. They have already obtained some observations from the Spitzer Space Telescope to better measure the planet properties, and they are currently discussing observations with the Hubble Space Telescope and other observatories to star probing the planet’s atmosphere.
