A study shows that polystyrene – commonly found in packing peanuts, cups, and plates – can be dissolved in biodiesel to improve power output. As researchers Najeeb Kuzhiyil and Song-Charng Kong of Iowa State University explain in a recent study published in Energy and Fuels, polystyrene accounts for about 22% of all high-volume plastics, by weight. Finding a method to convert these waste plastics into energy could potentially alleviate the strain on landfills and generate electricity. The study, funded in part by the Department of Defense, began with the goal of searching for solutions to trash disposal and power generation under battlefield conditions, where recycling is not usually an option. Although for most materials, recycling is more efficient than converting them into energy, polystyrene is so lightweight and bulky that it’s uneconomical to ship to recycling plants, and may be a good candidate for fuel conversion.In their study, the researchers used biodiesel as a recycling agent, into which they dissolved different amounts of polystyrene packing peanuts and tested the blended fuel in a tractor engine. As Kong explained, a polystyrene cup dissolves almost instantly in biodiesel, “like a snowflake in water.” By testing the fuel in a tractor engine, the scientists found that power output increased as polystyrene concentrations increased up to 5%. At concentrations above 5%, power output dropped off. As the researchers explained, polystyrene increases the biodiesel’s viscosity, which initially creates greater pressure inside the generator’s fuel injector that causes earlier fuel injection and increases output. But when the fuel becomes too thick, it doesn’t completely combust, decreasing power output. At a polystyrene concentration of 15%, the fuel injection pump overheats. Dissolving polystyrene in biodiesel doesn’t eliminate the problem of harmful emissions, however. The scientists found that adding polystyrene increases the fuel’s emissions of carbon monoxide, soot, and nitrous oxides, which don’t burn completely in the engine. But the researchers hope to improve the engine’s fuel injection system to achieve a more complete burn with fewer emissions. If they can reduce the emissions, they hope that the technology could offer economic and environmental advantages for power generation.More information: Najeeb Kuzhiyil and Song-Charng Kong. “Energy Recovery from Waste Plastics by Using Blends of Biodiesel and Polystyrene in Diesel Engines.” Energy and Fuels.

Samsung’s new flash chips for mobile devices © 2010 PhysOrg.com Citation: Taiwanese group introduces new MorPACK, stacked chip (2011, May 5) retrieved 18 August 2019 from https://phys.org/news/2011-05-taiwanese-group-morpack-stacked-chip.html Explore further In a paper submitted to iMAPS, author Shih-Lun Chen, of CIC, describes the structure of the MorPACK (short for morphing package) as a “heterogeneous integrated platform” of integrated parts that are put together as sort of building blocks, which allows the chipsets to require a smaller footprint. He also notes that due to the close proximity of the chips to one another in the stacked configuration, special care had to be taken to deal with heat issues; clearly something other’s that wish to consider the chipset in their electronic devices will want to take a close look at as well.The MorPack is built from the ground up; first, at the bottom is the processor, the biggest heat generator, which will likely sit atop a heat sink; above that are layer chips (connected by bridges) to provide linkage to memory chips, and then another to provide the same for peripheral devices. And then on top, come the custom chips designed by the companies that buy the MorPACK for use in their equipment.Chiueh Tzi-dar, director general of the laboratory at CIC where the chip was designed, in interviews has stated that the MorPACK could be used for virtually any device that currently employs integrated chips; which of course would include all the consumer devices we’ve all grown used to; such as cell phones, cameras, etc. If this turns out to be true, all such devices could eventually be made even smaller than they are now due to the smaller footprint needed for the chipsets inside; though the current configuration of the MorPACK is 4 x 4 centimeters, project development leader Chun-ming Huang says he believes he and his team can reduce it to just a fourth that size, making it small enough to fit in devices as yet unimagined. (PhysOrg.com) — Taiwan’s National Chip Implementation Center (CIC) has announced a new chip bundling design that they claim can cut development costs in half while also reducing the time it takes to bring a new chipset to market for a particular product, by as much as two thirds. Named the MorPACK, the chipset design uses a stacked approach, whereby newly designed chips can be stacked on top of existing processors (with air flow between them), reducing the space required to hold them, and increasing speed communication times between components as they are brought closer together.last_img read more

Shrinking device makes objects appear smaller than they are

A unit cell is shown in the inset. Image credit: Jiang, et al. ©2011 American Institute of Physics The team of engineers, led by Wei Xiang Jiang and Tie Jun Cui from Southeast University in Nanjing, China, has published their study on their shrinking device in a recent issue of Applied Physics Letters.“The shrinking device can shrink the size of an object virtually, so we named it a ‘shrinking device,’” Cui told PhysOrg.com. “Such a device works at microwave frequencies and will confuse the radar or other electromagnetic detection equipment to make wrong decisions. Hence it may have potential applications in the military.”The researchers built the shrinking device out of metamaterials, which are best known for their role in invisibility cloaks. When used in the field of transformation optics, metamaterials can bend light and control its path in desired ways.Here, the researchers used metamaterials to build eight concentric rings that are each 12 mm high. They then placed an arbitrary object, such as a spoon, in the center of the rings. When light waves propagate through the shrinking device, the wave fronts begin to bend and their wavelengths get compressed. When the light reaches the inner circular region, the wavelengths become decompressed. To an observer on the outside of the shrinking device, the manipulated light creates the illusion of a smaller object with the same shape as the real object.“The device is designed by using transformation optics, which make the objects in the real space and virtual space look like the same,” said Cui. “In our design, the real object is a large one and the virtual object is a small one. With the help of shrinking device, the scattering field of the large object becomes the same as that of the small one.”As the researchers explained, the shrinking device works somewhat like the beginnings of an invisible cloak since both devices involve shrinking the radius of the inner circular region. For the shrinking device, the radius of this space is always positive. But as the radius approaches zero, the shrinking device becomes a perfect invisibility cloak.“An object can be made to appear arbitrarily small as desired,” said Cui.The researchers demonstrated the shrinking performance both numerically and experimentally, and found that the experimental results agreed very well with the simulations. The results showed that the device had an overall “good shrinking performance,” with the illusion looking like an exact smaller version of the original object.As the researchers noted, because some objects’ proportions depend on their sizes, the shrinking device could even generate virtual objects of small sizes that do not exist in nature.In addition, the methods used here to design the shrinking device could be extended to design and realize other illusion devices, such as devices that can change some of the other parameters of an object. (PhysOrg.com) — By controlling how light bends around an object, researchers have built a shrinking device that makes objects appear smaller than they actually are. Although the original object does not actually shrink, the illusion of the smaller object is convincing enough to confuse viewers since the real size of the object cannot be perceived.

Diamond coupled to carbon nanotube could be used for quantum information processing

first_img Tiny diamonds could enable huge advances in nanotechnology © 2016 Phys.org The researchers, Peng-Bo Li et al., have published a paper on the new hybrid quantum device in a recent issue of Physical Review Letters.Diamonds and carbon nanotubes, which are both carbon allotropes, each have their own unique properties that make building such a device possible. Diamond contains defects called nitrogen-vacancy centers that emit highly coherent bright red light. The defects’ optical properties can be well-controlled so that they occupy one of two distinct states, which enables the defects to act as qubits. Carbon nanotubes, for their part, are well-known for their highly advantageous mechanical and electrical properties. Both diamonds and carbon nanotubes have been widely studied as separate entities, but rarely together as an integrated device. Recently, related research has shown that the nitrogen-vacancy centers in diamond can be coupled to a mechanical resonator, such as a vibrating cantilever, so that the magnetic (spin) properties of the diamond are coupled to the mechanical motion of the resonator. However, the coupling strength in these devices has always been relatively weak. The new work expands upon this idea by coupling a nitrogen-vacancy center in diamond to a carbon nanotube, which can be made to resonate by sending a 60-µA electric current through it. The researchers explain that the coupling between the nanotube and diamond defect occurs for the same reason that an electric current creates a nearby magnetic field, but on the quantum scale.”This device corresponds to a quantum version of Oersted’s classical experiment: a current-carrying wire creates a magnetic field around it, which will produce a force acting on a magnetic needle,” Li, a physicist at RIKEN in Saitama, Japan, and Xi-an Jiaotong University in China, told Phys.org.Due to the exceptional properties of the two carbon allotropes, the resulting hybrid device exhibits a magnetic coupling strength that is three orders of magnitude stronger than previous related devices. The interaction between the two components can also be tuned by controlling the electric current through the nanotube.The researchers’ proposal also shows that the quantum states of the nitrogen-vacancy center and the nanotube can be transferred to one another when they are coupled, as well as to a distant diamond’s nitrogen-vacancy center that is coupled to the same vibration mode of the nanotube. In the future, the nitrogen-vacancy centers could be used as qubits, and the ability to quickly and efficiently control these qubits’ states could form the basis of quantum information processing systems, and also be used as nanoscale sensors.”This device could be used to mechanically address quantum logic gates based on electric spins and could serve as novel nanoscale sensors for detecting tiny pressure, temperature, electric, and magnetic-field changes in the physical and life sciences,” Li said.The researchers also found that this device behaves very similarly to cavity quantum electrodynamics (QED) devices, so that further improvements might be made by applying the wealth of knowledge on cavity QED to the new devices.

In their recent study, they have shown that the electrified nanotube’s mechanical vibrations couple to the magnetic (or spin) properties of defects in the diamond.

Calculations show close Ia supernova should be neutrino detectable offering possibility of

first_img More information: 1. Warren P. Wright et al. Neutrinos from type Ia supernovae: The gravitationally confined detonation scenario, Physical Review D (2017). DOI: 10.1103/PhysRevD.95.043006 , Arxiv: https://arxiv.org/abs/1609.07403AbstractDespite their use as cosmological distance indicators and their importance in the chemical evolution of Galaxies, the unequivocal identification of the progenitor systems and explosion mechanism of normal Type Ia supernova (SN Ia) remains elusive. The leading hypothesis is that such a supernova is a thermonuclear explosion of a carbon-oxygen white dwarf but the exact explosion mechanism is still a matter of debate. Observation of a Galactic SN Ia would be of immense value in answering the many open questions related to these events. One potentially useful source of information about the explosion mechanism and progenitor is the neutrino signal. In this paper we compute the expected neutrino signal from a Gravitationally Confined Detonation (GCD) explosion scenario for a SN~Ia and show how the flux at Earth contains features in time and energy unique to this scenario. We then calculate the expected event rates in the Super-K, Hyper-K, JUNO, DUNE, and IceCube detectors and find both Hyper-K and IceCube would see a few events for a GCD supernova at 1 kpc or closer, while Super-K, JUNO, and DUNE would see a events if the supernova were closer than ∼0.3 kpc. The distance and detector criteria needed to resolve the time and spectral features arising from the explosion mechanism, neutrino production, and neutrino oscillation processes are also discussed. The neutrino signal from the GCD is then compared with the signal from a Deflagration-to-Detonation Transition (DDT) explosion model computed previously. We find the overall event rate is the most discriminating feature between the two scenarios followed by the event rate time structure. Using the event rate in the Hyper-K detector alone, the DDT can be distinguished from the GCD at 2σ if the distance to the supernova is less than 2.3kpc for a normal mass ordering and 3.6kpc for an inverted ordering. 2. Warren P. Wright et al. Neutrinos from type Ia supernovae: The deflagration-to-detonation transition scenario, Physical Review D (2016). DOI: 10.1103/PhysRevD.94.025026 , Arxiv: https://arxiv.org/abs/1605.01408AbstractIt has long been recognized that the neutrinos detected from the next core-collapse supernova in the Galaxy have the potential to reveal important information about the dynamics of the explosion and the nucleosynthesis conditions as well as allowing us to probe the properties of the neutrino itself. The neutrinos emitted from thermonuclear – type Ia – supernovae also possess the same potential, although these supernovae are dimmer neutrino sources. For the first time, we calculate the time, energy, line of sight, and neutrino-flavor-dependent features of the neutrino signal expected from a three-dimensional delayed-detonation explosion simulation, where a deflagration-to-detonation transition triggers the complete disruption of a near-Chandrasekhar mass carbon-oxygen white dwarf. We also calculate the neutrino flavor evolution along eight lines of sight through the simulation as a function of time and energy using an exact three-flavor transformation code. We identify a characteristic spectral peak at ∼10 MeV as a signature of electron captures on copper. This peak is a potentially distinguishing feature of explosion models since it reflects the nucleosynthesis conditions early in the explosion. We simulate the event rates in the Super-K, Hyper-K, JUNO, and DUNE neutrino detectors with the SNOwGLoBES event rate calculation software and also compute the IceCube signal. Hyper-K will be able to detect neutrinos from our model out to a distance of ∼10 kpc. At 1 kpc, JUNO, Super-K, and DUNE would register a few events while IceCube and Hyper-K would register several tens of events. (Phys.org)—A team of researchers at North Carolina State University has found that current and future neutrino detectors placed around the world should be capable of detecting neutrinos emitted from a relatively close supernova. They also suggest that measuring such neutrinos would allow them to explain what goes on inside of a star during such an explosion—if the measurements match one of two models that the team has built to describe the inner workings of a supernova. Supernovae have been classified into different types depending on what causes them to occur—one type, called a la supernova, occurs when a white dwarf pulls in enough material from a companion, eventually triggering carbon fusion, which leads to a massive explosion. Researchers here on Earth can see evidence of a supernova by the light that is emitted. But astrophysicists would really like to know more about the companion and the actual process that occurs inside the white dwarf leading up to the explosion—and they believe that might be possible by studying the neutrinos that are emitted. In this new effort, a team led by Warren Wright calculated that neutrinos from a relatively nearby supernova should be detectable by current sensors already installed and working around the planet and by those that are in the works. Wright also headed two teams that have each written a paper describing one of two types of models that the team has built to describe the process that occurs in the white dwarf leading up to the explosion—both teams have published their work in the journal Physical Review Letters.The first model is called the deflagration-to-detonation transition; the second, the gravitationally confined detonation. Both are based on theory regarding interactions inside of the star and differ mostly in how spherically symmetric they are. The two types would also emit different kinds and amounts of neutrinos, which is why the team is hoping that the detectors capable of measuring them will begin to do so. That would allow the teams to compare their models against real measurable data, and in so doing, perhaps finally offer some real evidence of what occurs when stars explode.

New study uncovers insights about the nature of the ultravioletbright star Barnard

first_img Citation: New study uncovers insights about the nature of the ultraviolet-bright star Barnard 29 (2019, March 11) retrieved 18 August 2019 from https://phys.org/news/2019-03-uncovers-insights-nature-ultraviolet-bright-star.html GHRS spectrum of Barnard 29. Credit: Dixon et al., 2019. Analyzing data from spectroscopic instruments, astronomers have reported fundamental properties of Barnard 29, an ultraviolet-bright star in globular cluster Messier 13. Results of the analysis, presented in a paper published March 1 on arXiv.org, provide important insights into the nature of this star. More information: William V. Dixon et al. Observations of the Ultraviolet-Bright Star Barnard 29 in the Globular Cluster M13 (NGC 6205). arXiv:1903.00350 [astro-ph.SR]. arxiv.org/abs/1903.00350 © 2019 Science X Network Barnard 29 has intrigued astronomers for over a century. It was described in the earliest studies as the most striking example of a star shining with a much bluer light than the great majority of the cluster’s other stars. According to more recent observations, Barnard 29 is classified as an ultraviolet-bright, post-asymptotic giant branch (AGB) star.Although Barnard 29 has been a subject of numerous observations, still many questions about its evolution and chemical composition remain unanswered. So a team of astronomers led by William V. Dixon of Space Telescope Science Institute in Baltimore, Maryland, has combed through the available data from the Hubble Space Telescope’s FUSE, COS and GHRS spectroscopic instruments and from the HIRES echelle spectrograph on the Keck I telescope in Hawaii. Analysis of this dataset allowed the researchers to determine chemical abundances for more than dozen elements in this star.”The availability of high-resolution, high signal-to-noise FUV and optical spectra allow us to confirm the star’s iron abundance and determine the abundances of many additional species,” the astronomers wrote in the paper.The research revealed that Barnard 29 has chemical composition typical for first-generation stars in Messier 13. The object was found to be richer in oxygen and poorer in aluminum than second-generation stars in this cluster.However, the star exhibits an underabundance of carbon and an overabundance of nitrogen, which indicates that it experienced a non-convective mixing on the red-giant branch (RGB) and did not undergo third dredge-up. Moreover, chemical abundances of Barnard 29 appear to have changed little since it left the RGB.”The abundance pattern seen in Barnard 29—C depletion and N enhancement relative to the average value for first-generation stars on the RGB—suggests that the star experienced the full impact of deep mixing,” the paper reads.Furthermore, the researchers found that Barnard 29 has an effective temperature of approximately 21,400 K and a mass of about 0.5 solar masses. They also found that iron abundance of this star is -6.05, consistent with the mean value for Messier 13.According to the paper, results of the study suggest that Barnard 29 evolved from a zero-age horizontal-branch (ZAHB) star with a mass of around 0.5-0.55 solar masses, near the boundary between the extreme and blue horizontal branches.”In light of stellar-evolution models, it seems likely that Barnard 29 is a post-HB star evolving from a ZAHB star with MZAHB between 0.50 and 0.55 M, a range spanning the EHB/BHB boundary. A post-HB star would have fully ascended the RGB, consistent with our suggestion that Barnard 29 experienced the full effects of non-convective mixing on the RGB,” the scientists explained.

AX J194982534 is a supergiant fast Xray transient observations confirm

first_img SFXTs are a class of high-mass X-ray binaries (HMXBs) with supergiant companions. They showcase significant X-ray flaring activity, experiencing outbursts with very fast rise times and typical durations of a few hours that are associated with supergiant stars.Located most likely some 22,800 light years away from the Earth, AX J1949.8+2534 (AX J1949 for short) was discovered almost two decades ago by the ASCA Galactic Plane Survey. Previous X-ray observations of this source suggested that it is a high-mass X-ray binary (HMXB) with a Be spectral-type companion (BeHMXB) or an SFXT. However, studies published in 2017, which reported the detection of bright flares in AX J1949, favored the SFXT scenario.Now, a team of astronomers led by Jeremy Hare of University of California, Berkeley, have published the results of new observations of AX J1949 using NASA’s Swift, Chandra and NuSTAR space telescopes. The observational campaign allowed them to uncover more details about the properties of this source, which could be decisive in determining its true nature.”In this paper, we report on Neil Gehrels Swift-XRT, Chandra, and NuSTAR legacy observations of the SFXT candidate AX J1949,” the paper reads.The observations revealed that AX J1949 exhibits rapid X-ray variability on kilosecond timescales. The study emphasized that a large number of still unidentified sources observed by ESA’s INTEGRAL spacecraft that showcase such variability, have been classified as SFXTs.Moreover, the researchers found that the AX J1949 binary contains an early B-type supergiant of the Ia luminosity class, which, according to the paper, confirms the SFXT nature of the studied object.”We find that an early B-type Ia is the most likely spectral type and luminosity class of the star, making AX J1949 a new confirmed member of the SFXT class,” the astronomers concluded.They added that in general, early supergiant B-type stars, have been found so far in about 40 percent of the known SFXT systems.Additionally, the observations allowed the authors of the paper to make new calculations regarding the distance to AX J1949 and to estimate the reddening of the system. They found that the binary is located most likely between 22,800 and 26,000 light years away, while its reddening is at a level of about 8.5 to 9.5. © 2019 Science X Network Explore further More information: Jeremy Hare et al.

The sleuths are also checking if Abbas’s family members had any personal enmity with anyone. No one has been arrested in this case yet. ENDlast_img read more

Smokers notice health warnings more on plainpackaged cigarettes

first_imgHealth warnings on plain-packaged cigarettes affect smokers more than those marked on branded packs, finds a new study. Warnings used on standardised packs were novel and larger than those on fully-branded packs – and displayed pictorial images on both main display areas, the team said. “Consistent with the broad objectives of standardised packaging, our research found that it was associated with increased warning salience, and thoughts about risks and quitting,” said lead researcher Crawford Moodie from the University of Stirling in Scotland. Also Read – Add new books to your shelf”This study adds to the growing body of evidence that standardised packaging reduces the appeal of tobacco products,” said George Butterworth, Senior Policy Manager at Cancer Research, UK. The study showed that smokers who bought standardised packs were more likely to have noticed and read the warnings compared to those who had never used standardised packs. Those who bought standardised packs also thought about the health risks of smoking and quitting and were more likely to have noticed a stop smoking sign on packs. For the study, the team included 1,865 current smokers aged 16 and above.last_img read more

Heavy pot smokers may need higher sedation dosage

first_imgPeople who regularly use cannabis may require more than two times the usual level of sedation when undergoing medical procedures, warns a new study. “Some of the sedative medications have dose-dependent side effects, meaning the higher the dose, the greater likelihood for problems,” said lead researcher Mark Twardowski from Western Medical Associates in Colorado, US. For the study, the researchers in Colorado examined the medical records of 250 patients who received endoscopic procedures after 2012, when the state legalised recreational cannabis. Patients who smoked or ingested cannabis on a daily or weekly basis required 14 per cent more fentanyl, 20 per cent more midazolam, and 220 per cent more propofol to achieve optimum sedation for routine procedures, including colonoscopy, showed the findings published in The Journal of the American Osteopathic Association.last_img read more

Drinking linked to poor grades

first_imgIndulging in one negative behaviour such as heavy drinking can lead college students towards a vicious cycle of poor lifestyle choices, lack of sleep, mental distress and low grades, a study has warned. For the study by researchers from Binghamton University in the US, 558 students from different US colleges completed an anonymous survey on academic performance, daytime sleepiness, substance use and mental distress. “We used a robust data-mining technique to identify associations between mental distress in college students with substance abuse, sleep, social behaviors, academic attitude and behaviours, and GPA,” said Lina Begdache, assistant professor at Binghamton University. Also Read – Add new books to your shelf”Positive behaviours such as abstinence from substance use, studious attitudes and responsibility toward work and family are reflective of a brain chemistry profile that supports mood and maturation of the prefrontal cortex of the brain,” Begdache said in a statement. “We identified potential cyclic behaviours that associate with severe mental distress that are linked to a change in brain chemistry that supports substance abuse, poor academic attitude and performance, poor sleep patterns, and neglect of family and work,” Begdache said. Also Read – Over 2 hours screen time daily will make your kids impulsive”The novelty of these findings is that we are proposing, based on the neuroscience of these behaviours, that one action may be leading to another until a vicious cycle sets in,” she said. Low mental distress in college students was associated with no substance abuse, responsible attitude toward learning as well as good academic efforts, high GPA (of above 3.0) and limited daytime sleepiness. Mild mental distress correlated with borderline work neglect and with a marginal negative association with grade-point average. Severe mental distress correlated with substance abuse, extreme daytime sleepiness, poor academic attitude and low GPA. This change in the direction of associations may reflect the neuroanatomical and neurochemical changes triggered by these factors that eventually contribute to mental distress. The results demonstrate that manageable lifestyle factors contribute to mental health in college students, which become potentially cyclic events that may impact academic performance. “These factors that are associated with mental distress in college students are controllable factors, meaning that proper education of students may reduce risk of mental distress on college campuses, which is on the rise,” said Begdache. “It is important for young adults to recognise that one behaviour may lead to a domino effect,” said Begdache. For instance, using drugs recreationally, abusing alcohol or using “study” drugs not only affects brain chemistry but may affect diet and sleep, which may further alter brain function and brain maturity, researchers said. Reduced brain maturity increases impulsivity, reduces emotional control and cognitive functions as well as GPA, eventually increasing mental distress with a potential long-lasting effect,” said Begdache. The researchers also identified a ‘virtuous cycle’. When young adults follow a healthy lifestyle (diet, sleep and exercise), they are more likely to avoid drugs and alcohol, which supports a normal brain maturity, which is then reflected in a higher GPA and responsible attitudes toward learning, work and family.last_img read more

100 Years of Beauty Legends that Defined their Generations

first_imgIn addition to beauty being in the eye of the beholder, it is also a subject of trends and fashion. When it comes to female bodies especially, and the upheld image of what is beautiful it was always connected to the fashion industry and leading role models of the era. Common ideals of perfect proportions come and go almost as fast as fashion trends. From the pen-and-ink drawn Gibson girl in the 1910s to fuller-frame curvy bodies we adore today, the “most desirable” figure has rapidly changing. Every decade had its own standards and stars that were epitomizing the beauty ideal. 1910s Gibson GirlGibson Girls at the beachThe Gibson Girl was artist Charles Dana Gibson’s interpretation of the fashion industry’s “New Woman,” a response to the new freedoms for women won by the Suffrage Movement.Gibson girl model Camille Clifford, 1910.Her illustrations portraying a slender yet voluptuous, fragile yet independent female image first appeared in the 1890s and became a standard for beauty for the next 20 years. Two of the most famous Gibson girls — the personification of this perfect female body ideal — were the American-Belgian stage actress Camille Clifford and Evelyn Nesbit.1920s Flapper GirlLouise Brooks in her prime.The 1920s are characterized as the flapper girl epoch. The flapper was young and stylish; she had a much thinner frame than her predecessor as poverty was the defining feature of the era.Norma Talmedge 1910sMany women, unfortunately, did not even have to diet to keep their bodies thin. However, it is an epoch that brought dieting to the table. Beauty idol stars of the ’20s include silent screen actresses Olive Thomas and Alice Joyce.3) 1930s The SirenJean Harlow as Kitty Packard in ‘Dinner at Eight’.With the economic situation improving between the two great wars, many women had greater access to larger quantities of food. This fact alone brought curves back into the picture. Jean Harlow, the “Blond Bombshell,” was the curvy icon known for her “Laughing Vamp” movie persona. Her body became the next new perfect, and she also inspired a more daring and naked look that accentuated female sexuality.4) 1940s The Screen QueenKatharine HepburnThe 1940s women were on average an inch bigger than the flapper girls of the 1920s, and the slim-waisted curvy figure was making a comeback. It was in 1940 that the career of “natural beauty” Katharine Hepburn stepped up to the next level when she bought her own contract, along with the film rights to Philadelphia Story.Hepburn’s refusal to be molded into a sex symbol made her just that — she defied the norms of sexuality, among other strongly upheld progressive opinions. She brought strongly defined cheekbones and a confident air to the table. Women’s fashion of the day ranged from fitted suits to belted flowery dresses.5) 1950s The CurvesMarilyn MonroeWhen we think about the 1950s, beauty icons Marilyn Monroe and Elizabeth Taylor are sure to immediately come to mind. Contrary to the 1920s invention of the diet pill, the ’50s saw the promotion of weight gain and it was a decade where the weight gain pill was invented. Women were expected to be bigger — and bustier — in order to be considered feminine.6) 1960s The PetiteA drawing of Twiggy, by Flickr user Failuresque CC BY SA 2.0In stark contrast to the 1950s, without any smooth transition, the 1960s was the era of skinny the era of Audrey Hepburn. Imagine going from Marilyn Monroe to Twiggy in only a decade. Trying to emulate the child-like frame of Twiggy or Jean Shrimpton sent women the world over into dieting cycles. The mini-skirt was invented for girls to show off their thin legs.Audrey Hepburn7) 1970s The Pin UpPhoto of Farrah Fawcett from the television program Charlie’s Angels.The 1970s still promoted lean bodies, with wider shoulders and thinner hips. However, curves were also acceptable, but only when in right places. It was a time of dancing queen bodies, such as Farrah Fawcett.8) 1980s The SupermodelLinda Evangelista. Photo by jusez CC BY SA 2.0Elle MacPherson and Linda Evangelista, the “leggy” models set some high standards for women.

The grunge subculture emerged into the mainstream and influenced prevailing beauty ideals, promoting thin, androgynous bodies. Despite the controversy surrounding the emaciated look, pale skin, dark heavy eyes, and unhealthy thinness, it remained popular throughout much of the decade.10) 2000s The ToneGisele Bündchen in 2006. Photo by Tiago Chediak CC BY 2.0Christina Aguilera and Britney Spears, together with model Gisele Bundchen promoted a healthier and more toned look in comparison to the ’90s.

The Oldest DNA Ever Sequenced Came From a 700000yrold Horse

first_imgScientists who specialize in sequencing and analyzing ancient DNA have formidable obstacles to overcome; among them the deterioration and contamination that is to be expected in bones and teeth over thousands of years. It helps if the specimen is mummified and found in ice, such as Otzi the Iceman, who is estimated to have lived between 3400 and 3100 BC. But no DNA discovery has come close to the record set with the 2003 discovery of a frozen horse in the ancient permafrost of the Yukon in Canada, not far from the Alaska border.Using a new combination of techniques, scientists were able to sequence its genome and date the remains of the horse to 700,000 years ago. It took years of effort because the the DNA was heavily degraded and the bone itself had adopted some microbial residents with their own DNA.Reconstruction of Otzi the Iceman. Photo by Thilo Parg CC BY SA 3.0The scientists’ results were published in 2013 in the journal Nature.According to history.com, “The five-inch hind-toe bone fragment that the team used to decipher the ancient horse’s genetic code was unearthed in the Thistle Creek region of the Yukon’s Klondike gold mines. Because the fossil bone was preserved in permafrost, the horse’s DNA remained very cold and very dry, which slowed the disintegration process that usually begins immediately after death.”The main reason scientists took so long is that much of the fossil was contaminated by much more current bacteria: For every 200 DNA molecules sequenced, only one was actually from the Thistle Creek horse, according to researchers.Photo of reintroduced Przewalski’s horse taken at the “Seer” release site. Photo by Claudia Feh  CC BY-SA 4.0“We knew that sequencing ancient genomes as old as 70,000 to 80,000 years old was possible,” said Ludovic Orlando, an evolutionary geneticist with the Natural History Museum of Denmark at the University of Copenhagen, in an interview.” So we said, why not try even further back in time?”Orlando and colleagues were able to piece together the DNA from a horse they know was male. Their work helped them determine that the Equus lineage — which includes not only the modern horses but also zebras and donkeys — arose 4 to 4.5 million years ago, or about 2 million years earlier than previously thought, said National Geographic.A Przewalski’s horse in the Chernobyl Exclusion Zone. Photo by IAEA Imagebank CC BY SA 2.0The horse was found because another evolutionary biologist of the University of Copenhagen joined a team of geologists on a 2003 expedition to the Yukon. While exploring a site that contained ice and volcanic ash, the scientist spotted a piece of bone sticking out of the frozen ground and decided to take it back for sampling.Previous to the Thistle Creek horse analysis, the oldest genome ever sequenced was that of a 120,000-year-old polar bear. Scientists theorize that the 700,000-year-old horse was about the same size as a modern-day Arabian horse.Polar BearOtzi the Iceman is a comparative youngster to the Thistle Creek Horse. He was discovered by hikers on the Alps on the Austrian-Italian border in 1991. The find was at an elevation of 10,500 feet. At first the hikers thought they’d found the corpse of a lost mountain climber. Scientists eventually confirmed that Otzi perished thousands of years ago in the Late Neolithic era, at about the same time as the invention of the wheel.Read another story from us:  Ready to Flee the Volcano – Rare Harnessed Horse Found in Pompeii RuinsJurassic Park aside, studies of ancient DNA suggest that sequences older than 1.5 million years will be too short to be readable. Right now it seems impossible that DNA will be recovered from dinosaurs, since they disappeared 65 million years ago, except for the lineage that leads to modern birds.last_img read more

Local roller skater places third at national championship

first_imgBy Bonnie Adams, Managing EditorRegion – Ever since she was a little girl, Samantha Kiley of Berlin has loved to roller skate.“I started at age 7, going to a lot of parties that were held at the Hudson Roller Kingdom,” she recalled. “I also participated in an after school program. It was so much fun.”Now 25, Kiley is still enjoying the sport she loves. And, recently, her many years of hard work and dedication paid off when she placed third in the Classic Gold Women’s Single Dance at the 2019 National Roller Figure Championships held in Spokane, Wash.In the competition, skaters first perform a compulsory dance and then an original one which shows off their personality and creativity. Kiley first performed the “Emerald Cha Cha” for her compulsory dance and for her creative dance, a routine she named, “That’s Life.”In her dances, she is graceful and poised, demonstrating moves, footwork and edges that she makes look very easy, belying the technical expertise needed to execute them.Even when she was a college student at St. Anselm College in Manchester, N.H., studying math, she still found time for her passion.“It was difficult to find the time, but luckily Roller Kingdom’s sister rink, in Tyngsborough, which was not too far away, was nice enough to let me practice there,” she said.Now a software automation engineer, her schedule is even tighter. But she still finds the time to practice nearly every day.“It’s a little rough,” she admitted, “but I find the time at nights and on weekends.” Kiley has also taken up sewing as a way to help her coach Heidi Permatteo, who makes many of the skaters’ at the rinks’ outfits.“I just want to help her out because she does so much,” Kiley said.Permatteo has been Kiley’s coach since she started skating. She has on occasion also taken lessons with Jodee Viola, whose family has been one of roller skating’s iconic families for decades.Kiley also helps out at competitions, using her math skills to do tabulations which help determine placements. In doing so, she is following in the footsteps of her mother, Jane, who passed away in 2017.“She did tabulations for a long time,” Kiley said. “She was always at my competitions.”Her father, John, who lives in Berlin, and her grandmother, Lidia Kiley, who lives in Southborough, continue to cheer her on.“We’re really proud of her and her hard work paying off,” John said.Lidia was not able to travel to Spokane to watch the competition, but was able to enjoy it afterwards when her granddaughter showed her video clips of her performances.“She was just beautiful,” Lidia said.Going forth after the excitement of this year’s Nationals, Kiley is excited, she said, to continue improving.“Skating is something you can do forever,” she said. “I love it so much. I cannot see myself ever getting out of it.”last_img read more

Right on diva wide receivers Wrong on the South Beach boat trip

first_imgWhere Colin was WrongOdell Beckham set himself up for criticism with the boat trip – When the news of the South Beach boat trip broke, Colin said it wasn’t a big deal. Players have been getting away on their off days for years, and he’s fine with it. But, following the loss, whether it’s right or wrong, the boat trip was the central topic of discussion.Colin doesn’t blame Beckham for taking the trip, but he does blame him for posting the night out on social media, which gave his critics all the ammunition they needed to connect the loss and the trip. Distractions are distractions, and this clearly ended up being a huge one. Colin was wrong.Joe Buck and @TroyAikman talking about #Giants Odell Beckham’ struggles after the boat incident during #Packers game pic.twitter.com/7BpZghIOQc— Dov Kleiman (@NFL_DovKleiman) January 9, 2017 Where Colin was RightDerek Carr should be a top MVP candidate – Colin was among the first to get behind Derek Carr as an MVP candidate during the Raiders impressive season and first playoff appearance since 2002.Anyone who questioned how valuable Carr is to the Raiders just needed to watch how below-average Oakland was without him following his broken leg in Week 16. Yesterday, with Connor Cook under center, the Raiders were just 2 for 13 on third down and could barely move the ball. Carr was the driving force behind Oakland’s return to relevance. Colin was right.That should seal it. Connor Cook misses Amari Copper and it’s picked off by Corey Moore. #wearetexans #HOUvsOAK pic.twitter.com/vxxN5B5uc2— Chat Sports (@ChatSports) January 8, 2017 Clemson vs. Alabama national championship game – Colin had the Tide at #5 in his preseason college football poll because he didn’t know who they would play at quarterback. It became clear early on that they found the answer in freshman Jalen Hurts. Ever since Hurts took over signal calling duties against USC in the opener, the Tide have been dominant.Colin did have Clemson ranked #1 in his poll, but bailed on the Tigers at numerous points during the season because of inconsistent showings against inferior competition. He didn’t think there would be a rematch of last year’s championship game. Tonight, we have it. Colin was wrong. Advertisement Where Colin was WrongThe Blasé 4 – Colin picked all 4 Wild Card games ATS and went 1-3 – he hit on Pittsburgh -10. He was 4 for 4 picking winners, but that doesn’t get you paid in Vegas. He definitely wouldn’t have touched the Raiders/Texans game in a million years if he had a choice. Still, a losing week is a losing week. Colin was wrong.Where Colin was RightThe 49’ers organization was the problem, not Chip Kelly – The 49’ers gave Chip Kelly Blaine Gabbert and Colin Kaepernick as his quarterbacks, and still fired him after less than a year. No one could have won with either quarterback. GM’s are reportedly being told to steer clear of the Niners because of meddling winner Jed York. Everyone loves to blame the coach, but this mess isn’t Kelly’s fault. It’s an organizational grease fire.

In the 4 games this season where Beckham had over 100+ yards, the Giants were 1-3. Star wide receivers are the dessert for NFL teams, not the entrée.Colin has repeatedly said that games in the NFL are won and lost based on the coach, quarterback and offensive line.

NFL Wild Card weekend is in the books, and Colin misfired on his Blasé 4 playoff picks ATS, even though he picked all the winners. He thinks the playoffs have proved his theory that diva wide receivers don’t win games, but he underestimated the potential fallout from the Odell Beckham South Beach boat trip. And, after watching the Raiders struggle without Derek Carr against the Texans, he feels more strongly than ever that Carr should be at the top of any MVP list.Here’s the right and the wrong from the past week: Where Colin was RightThe Super-Warriors aren’t clear of chemistry issues – The Warriors have played an amazing brand of team basketball this year with Kevin Durant, but they still aren’t out of the woods yet in terms of team chemistry, yet.On Friday, Draymond Green was spotted shouting at Durant during a game in a tense late game exchange. Green is the only one of the Big 4 that has yet to find his role in the star alignment, and until he is happy, there exists the potential for him to be a disgruntled chemistry disruptor.

Three Issues to Consider Before Moving to the Cloud

first_imgNovember 28, 2011 Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now Opinions expressed by Entrepreneur contributors are their own. By letting a cloud services vendor store your company’s files and applications online, you can easily expand in-house storage capacity and processing muscle as your business grows. Let’s say you have a surge of new orders on your e-commerce system or you need to expand processing power for an application. Your vendor can boost your computing capabilities to satisfy those needs.But there can be some risks associated with moving to the cloud. What if your vendor goes bankrupt and closes? What if its technology fails, leaving you unable to access your sensitive business data?Migrating valuable business information to a technology vendor is a big move and can require a lot of consideration. Here, we look at three of the most important factors to consider when making the transition for your company.1. Research the vendors.Because it’s relatively easy to offer cloud services, your choices will range from larger, established companies to unknown startups. The small players may be competent, but be sure you feel comfortable being among the first to put them to the test.To assess vendors, ask for customer references, talk to other companies you trust and do some research online. The ideal vendor will have a strong track record for both performance and customer service.Related: How One Small Company Outsourced IT to a Cloud-Computing PlatformFor example, low latency — the delay in moving data from one point to another — is an important measure to check. Prompt and reliable service is critical because your cloud provider is essentially your new outside information technology department. If the vendor is slow to deal with your problems, your response time to customers also will likely suffer.2. Be aware of legal issues.Understand your potential legal liabilities and ensure that your cloud vendor abides by the same rules that govern your company.Your business may have internal audit rules that demand careful handling of sensitive information. If you’re in a regulated industry or do business with the government, you also may be subject to restrictions on handling data.Related: How to Move Your Business Data into the Cloud SafelyMake sure the vendor also understands the latest privacy laws affecting your business and that it states in writing its commitment to confidentiality and its methods for securing your data. “As your data is stored in the same storage space as your neighboring tenants, you need to know how your cloud vendor will ensure that your data isn’t illegally accessed,” says Ian Huynh, vice president of engineering at Hubspan, a cloud services integration company.3. Consider a back up to the cloud.Your data will likely be just fine in the servers of a cloud services vendor. I’ve been using online services for years and have never lost data. But if you would like an added measure of security, you might want to regularly back up data stored in the cloud.You could manually export your information from the cloud and back it up on-site. Or you could select a cloud backup service from such companies as Symantec, CloudBerry, KineticD and CTERA Networks, which typically allow users to keep copies of their cloud data on local servers or in other locations.Related: Still Foggy on Cloud Computing? Installing software on a server or local computer hard disk has been the traditional way of using computers for years. However, online software offers growing businesses a much faster, more productive and more cost effective way to create, manage and move information. Just be cautious about what software you can move securely to the cloud.
