first_img Explore further Citation: Experiment to Clarify Ancient Physics Discovery Yields More Questions (2007, August 28) retrieved 18 August 2019 from https://phys.org/news/2007-08-ancient-physics-discovery-yields.html Scientists at Rutgers University have recently completed an experiment designed to help illuminate the phenomenon (known as the triboelectric effect) – but that initially left them scratching their heads instead.In the July 31, 2007, online edition of Physical Review Letters, they describe their experiment: separating a mixture of red and blue “art-sand” particles by pouring them into a positively charged acrylic cylinder using a miniature version of a “vibratory feeder,” a machine typically used to move dry goods from storage hoppers into processing machines. The scientists charged the cylinder triboelectrically by rubbing it with a nylon glove. Based on this initial condition, they expected to the grains to exhibit certain behaviors.As the grains traveled down the feeder, they became positively charged due to friction. When they reached the end and fell through the air, they cleanly separated into two streams – one red and one blue – and formed two piles on the bottom of the cylinder. The experiment is similar to one performed in the 19th century by British physicist Lord Kelvin, who noticed that a charged stream of water droplets induced a charge in a second water-droplet stream positioned next to it.Due to the slightly different chemical composition of the grains, the blue grains pick up slightly more positive charge than the red. The scientists assumed, based on the law of electrostatics, that each positively charged blue grain would induce a negative charge on the metal feeder. Accordingly, they reasoned that because the blue grains have more positive charge, they would feel a stronger pull toward the feeder than the red and fall as close to the feeder as possible.Oddly, the opposite behavior occurred: The red grains fell closer to the feeder.Upon examining the feeder, the group noticed that a small beard of red grains, perhaps five or 10 grains thick, had built up on the feeder lip. This was also odd, since the blue grains carry more positive charge and were more likely to stick. Further, no blue grains stuck to the beard, but rather, as the scientists write, a “paradoxical repulsion” took place. The blue grains glided over the red and over the edge.Thus, the two colors separated before they fell. It appears, therefore, that the positive charge on the cylinder did not influence the grains’ behavior.Fernando Muzzio, a scientist involved in the study, told PhysOrg.com that he and his colleagues had also subjected some “real-world” materials to the same experimental setup, including typical pharmaceutical powders, which have the potential to experience these triboelectric-induced issues during processing. The group observed essentially the same results.“I suspect that once we start looking, we will find similar unexpected behaviors in many places. It remains for future study to determine the extent to which these phenomena can be controlled to avoid quality problems, or even better, to develop new methods of processing,” Muzzio said.Citation: Amit Mehotra, Fernando J.

Computer Keyboard Hacking

first_img New computer attack mimics user’s keystroke characteristics and evades detection The researchers found that most modern keyboards generate electromagnetic emanations that can be used to decipher the keystrokes remotely. They used some basic instruments to “sniff” these electromagnetic emissions, which eventually helped them to decipher the keystrokes typed.By using a wireless aerial, keystrokes were sniffed from a computer located a meter away. Once the data is sniffed, it is converted into decipherable text with software developed by Vuagnoux.Another test revealed that keystrokes, from a computer in an adjacent room 20 to 30 feet away, could be deciphered by using a larger antenna. It has been conclude that wired computer keyboards, sold in stores, generate compromising emanations that make it not safe to transmit sensitive information.Electromagnetic eavesdropping dates back to as early as the mid 1980s, if not earlier. But Researchers say many of today´s keyboards have been adapted to prevent those attacks from working. Current research now shows that even these keyboards are vulnerable to electromagnetic sniffing.It can be seen that such attacks would be limited due to electromagnetic interference from other electrical devices. The other thing that makes the attack unfeasible is the amount of sophisticated equipment required. Given all the fuss and expense, why not just use a more conventional method.

Astronomers study the merging galaxy cluster Abell 3376 and its radio relics

first_img Explore further Using the Suzaku space telescope, astronomers have conducted an X-ray spectral study of the nearby merging galaxy cluster Abell 3376 and its two arc-shaped radio relics. The new research reveals more insights into the properties of the radio sources in this cluster. The findings are presented in a paper published June 20 on arXiv.org. This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Two radio relics discovered in the galaxy cluster Abell 168 © 2018 Phys.org Abell 3376 is a nearby bright and moderately massive merging galaxy cluster. It has two giant arc-shaped radio relics in its outskirts. Radio relics are diffuse, elongated radio sources of synchrotron origin, occurring usually in the form of spectacular single or double symmetric arcs at the peripheries of galaxy clusters.Merging galaxy clusters like Abell 3376 are excellent places to search for radio relics and study them, as such sources originate in acceleration and re-acceleration at merger shocks. However, given that the number of known radio relics associated with merger shocks is still small, astronomers are interested in more detailed studies of those sources already identified in merging systems.Abell 3376 with its radio sources has been a subject of a recent study conducted by a team of researchers led by Igone Urdampilleta of the SRON Netherlands Institute for Space Research in Utrecht, The Netherlands. They analyzed observational data collected by the X-ray Imaging Spectrometer (XIS) onboard NASA/JAXA Suzaku astronomy satellite, complemented by archival data provided by ESA’s XMM-Newton space telescope and NASA’s Chandra X-ray observatory.The analysis uncovered more details regarding the properties of Abell 3376’s radio relics and could contribute to better understanding of the process of galaxy merging.”We present an X-ray spectral analysis of the nearby double radio relic merging cluster Abell 3376 (z = 0.046), observed with the Suzaku XIS instrument. These deep (~360 ks) observations cover the entire double relic region in the outskirts of the cluster,” the astronomers wrote in the paper.As a result of the analysis, the researchers confirmed that Abell 3376 exhibits a stronger merger shock in the western direction (coincident with the radio relic in the West), a weaker shock in the East (possibly associated to the “notch” of eastern relic), and a cold front. The velocities of the western and eastern shocks were calculated to be about 1,630 and 1,450 km/s respectively.When it comes to the cold front, the astronomers found that it is located approximately 490,000 light years from the X-ray emission peak at the center and delimits a cool gas cloud moving with a velocity of approximately 1,300 km/s.Furthermore, assuming that the shock fronts are moving with constant velocity, Urdampilleta’s team found that the time since core passage is about 600 million years, which is in good agreement with previous simulations and with earlier multiwavelength analyses. The authors of the paper emphasize that their results confirm that Abell 3376 is still an evolving merging cluster.”Based on the shock speed calculated from the Mach numbers, we estimate that the dynamical age of the shock front is ~0.6 Gyr after core passage, indicating that Abell 3376 is still an evolving merging cluster and that the merger is taking place close to the plane of the sky,” the scientists concluded.

More information: X-ray study of the double radio relic Abell 3376 with Suzaku, arXiv:1806.07817 [astro-ph.GA] arxiv.org/abs/1806.07817AbstractWe present an X-ray spectral analysis of the nearby double radio relic merging cluster Abell 3376 (z = 0.046), observed with the Suzaku XIS instrument. These deep (∼360 ks) observations cover the entire double relic region in the outskirts of the cluster. These diffuse radio structures are amongst the largest and arc-shaped relics observed in combination with large-scale X-ray shocks in a merging cluster. We confirm the presence of a stronger shock (MW = 2.8 ± 0.4) in the western direction at r∼26′, derived from a temperature and surface brightness discontinuity across the radio relic. In the East, we detect a weaker shock (ME = 1.5 ± 0.1) at r∼8′, possibly associated to the ‘notch’ of eastern relic, and a cold front at r∼3′. Based on the shock speed calculated from the Mach numbers, we estimate that the dynamical age of the shock front is ∼0.6 Gyr after core passage, indicating that Abell 3376 is still an evolving merging cluster and that the merger is taking place close to the plane of the sky. These results are consistent with simulations and optical and weak lensing studies from the literature.last_img read more

Rhythmic oscillations detected in the blazar Markarian 501

first_img Blazars, classified as members of a larger group of active galaxies that host active galactic nuclei (AGN), are the most numerous extragalactic gamma-ray sources. Their characteristic features are relativistic jets pointed almost exactly toward the Earth. In general, blazars are perceived by astronomers as high-energy engines serving as natural laboratories to study particle acceleration, relativistic plasma processes, magnetic field dynamics and black hole physics.Located some 456 million light-years away, Markarian 501 (or Mrk 501 for short) is a blazar or a BL Lac source, with a spectrum extending to the highest energy gamma rays. It is one of the nearest blazars that shines bright in the X-ray and one of the earliest extragalactic sources detected in the TeV band.Within the last decade, Mrk 501 was observed by the Large Area Telescope (LAT) of NASA’s Fermi Gamma-ray Space Telescope. A group of astronomers led by Gopal Bhatta of the Astronomical Observatory of the Jagiellonian University in Kraków, Poland, has analyzed the observational data of Mrk 501 collected by LAT between August 2008 and June 2018. The study resulted in the detection of rhythmic oscillations in the blazar’s gamma-ray emission.”In this letter, we report the detection of transient rhythmic oscillations in the about 10-year long Fermi/LAT observations of the famous blazar Mrk 501,” the researchers wrote in the paper.According to the study, the astronomers found a strong signal of quasi-periodic oscillation (QPO) with a periodicity of around 332 days. They added that the gamma-ray flux modulations in this blazar gradually decayed in strength during the recent years.Furthermore, the researchers emphasized that the gamma-ray QPO in Mrk 501 persisted nearly seven cycles until it finally weakened. Given that not many gamma-ray QPOs have been found to show more than five cycles, the case of Mrk 501, according to the authors of the paper, might be one of the few examples in which astronomers witness a relatively high frequency with a period of less than a year.”What we have observed might be the first interesting event where we witness a transient gamma-ray periodic modulations in the high energy emission of the blazar that persist up to 7 cycles before they gradually fade away,” the paper reads.The study also presents several hypotheses about what could be the driving force behind such rhythmic oscillations in Mrk 501. The scientists suggest various scenarios, including supermassive binary black holes, jet precession and accretion disk precessing under gravitational torque. However, the researchers concluded that further analysis of Mrk 501 and discussion on the topic are needed in order to definitely determine the most plausible theory explaining the origin of the oscillations in this blazar.

Patent talk Newcar smell removal courting consumers in China

first_img Phoebe Wall Howard in Detroit Free Press reported that Ford filed a patent application for an odor-removal process that gets rid of new-car smells once the car is purchased. “The car would determine whether conditions are right to expel compounds, and the car would drive itself to a place in the sun and bake away the offensive odor.”This might make some American new-car hopefuls scratch their heads over what could be bad about the new-car smell, but there it is: consumer tastes in different parts of the world are not the same. “Consumers in China say they hate the new car smell,” said the Detroit Free Press. “Consumer feedback from Chinese buyers in recent years has been consistent. More than 10 percent of drivers complained about the issue according to the 2018 J.D. Power China Initial Quality Study,” said Howard.Yes, but that is just China. Ford has the rest of the world to delight, so why be so concerned? Detroit Free Press: “China is the largest car market in the world, so carmakers take notice.” [Smell testers pay attention to odors of every car item, from floor carpets to steering wheel. The goal is to reject any that may offend a buyer, Quartz noted.] J.D. Power’s Brent Gruber was quoted as saying that, in that market, unpleasant interior smell/odor remained the top industry problem. “To put that in context, it is nearly double the problem rate of the second most prevalent problem, excessive fuel consumption.”As for a new-car analysis of what constituents cause the smell, the finding was that it is a result of “volatile organic compounds given off by leather, plastic and vinyl,” said Howard. In addition, smell contributors may be the chemicals used to attach and seal car parts. The Verge named the source of “new car smell” as having to do with heating of materials such as wood and leather.

Love the smell of a new car!” How often have you heard from that from a starstruck passenger getting his or her first ride in your cruiser. Not so fast. One man’s new-car nirvana is another’s eeew. Evidently, Ford is thinking of not having to appease either side by keeping it simple stupid: bake out the smell altogether. Ford has an application for a patent that features a system to put an end to the smell. © 2018 Science X Network Video: Petrichor, the smell of raincenter_img This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. So, what does the patent talk about as a solution? Speed up the heating process. Bake it off. Quartz elaborated: “The baking process would be accompanied by opening at least one window, turning on the heater, turning on the fan, or running the engine. Ford’s proposed system would use sensors to determine if the intensity of the sunlight and the ambient temperature are high enough to trigger the off-gassing and to measure the level of VOCs.”Sean O’Kane, The Verge: “The patent application describes semi-autonomous or fully autonomous cars driving themselves to a nice, sunny spot (probably on some hot asphalt), parking, turning on the heat, slightly cracking the windows, and intermittently running the engine. In this scenario, the vehicle ‘bakes’ away the ‘new car smell.'”Beyond the process devised as a solution in the patent filing, the interesting outcome of this patent application is in the disclosure itself that was spotlighted, a smell perception divide between the U.S. and China. That disclosure is that the very same smell that delighted Americans turned off Chinese. Is smell that much of a cultural mystique?Actually, reader reactions and story comments on various sites offered interesting responses to explain divided opinions over whether a new car represented scent or stink.Americans, suggested one reaction, had positive smell associations, regarding a car as a new as a new addition in life—like walking into a new house, with all its smells of stray shavings, paint thinners and cleaning solvents.In China, consumers might be especially concerned over factory fallout versus public health. “As Quartz has reported in the past, Chinese consumers who are car shopping think the odor is a bigger problem than poor fuel economy and wind noise, as some worry the smell could be a health hazard.”Last year, a Journal of Environmental Sciences paper titled “Ambient volatile organic compounds pollution in China” said that “Owing to rapid economic and industrial development, China has been suffering from degraded air quality and visibility. Volatile organic compounds (VOCs) are important precursors to the formation of ground-level ozone and hence photochemical smog.” The authors stated that VOCs elicited not only public concern but also a new impetus to scientific interest.

Kolkatans scamper for warmth as city sees coldest day in 4 years

first_imgKolkata: The city experienced its coldest day in 4 years on Wednesday as the mercury dipped to 12 degree Celsius, two degrees below normal.The minimum temperature in the city and its adjoining areas may drop further in the next couple of days. The mercury may hover around 10 degree Celsius by the end of the year, predicted the Regional Meteorological Centre in Alipore. Earlier, the city’s temperature had dropped to 12.9 degree Celsius on 14 December this year. Also Read – Rain batters Kolkata, cripples normal lifeThe winter chill has been intensified due to the uninterrupted flow of the northwesterly wind, which brings the cold wave into the South Bengal districts. “The minimum temperature may hover around 10 degree Celsius in the next few days. It is unlikely to fall any further,” said a senior official of the Regional Meteorological Centre. According to the Met office, a cold wave condition may prevail in some districts. The winter chill has been more intense in North Bengal, with Darjeeling touching 3 degree Celsius. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedThe Met office also said that the visibility would be considerably reduced in several parts of the South Bengal districts, particularly during the morning hours, due to mist. The temperature has dropped because of a north-western cold wind and will remain a few degrees below normal for the next few days. The minimum temperature dipped to 8 degree Celsius in Sriniketan and 9 degree Celsius in Asansol. The mercury plummeted to around 10-11 degree Celsius in Bankura and West Midnapore, while Diamond Harbour in South 24-Parganas remained at 11 degree Celsius on Wednesday. According to a weather expert, for the past few days water vapour in the air was high in the city, which resulted in mist especially in the morning. As the vapour started evaporating, people started witnessing a cold spell. Pavement dwellers were seen warming themselves beside small fires in districts like West Burdwan, Birbhum, Purulia and Bankura, as the temperature plunged. A cold spell has been continuing in various North Bengal districts and some South Bengal districts as well. According to the weather official, it looks like the cold spell may continue for quite some time. The flow of cold wave had been interrupted in the state two weeks ago, following the formation of a low pressure trough over Bay-of-Bengal and a cyclonic circulation. After the low pressure trough cleared, the temperature started dipping across the state.last_img read more

CPIM heavyweights keen to join BJP Partha Chatterjee

first_imgKolkata: Trinamool Congress secretary general Partha Chatterjee said on Saturday that some heavyweight CPI(M) leaders are keen to join the BJP which has become clear with leaders like Khagen Murmu and Mahfuza Khatun joining the saffron party.”A number of ground-level and middle-level CPI(M) leaders have been constantly shifting to the BJP for the last few years. But now, we are witnessing that openly with some senior leaders of the party running after the BJP leaders. The cases of Khagen Murmu and Mahfuza Khatun shifting to the saffron party just before the elections is a clear pointer. The leadership lacks organisational strength and the CPI(M) should try to prevent this trend of their party people rubbing shoulders with the BJP,” Chatterjee said at ‘Meet the Press’ programme hosted by Calcutta Press Club. Chatterjee’s reactions came in reply to a poser when CPI(M) state secretary Surjya Kanta Mishra alleging that TMC and BJP are having a tacit understanding. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: Mamata”No other leader from the country has been fighting against the anti-people policies of the BJP government so strongly like our party supremo Mamata Banerjee. The people of the country are well aware of this,” he reiterated. It may be mentioned that Murmu, who was the former CPI(M) MLA from Habibpur in Malda, had already contested the Lok Sabha elections from Malda North with a BJP ticket. He had joined the BJP in March. Khatun, who was an elected CPI(M) MLA from Kumarganj Assembly constituency in 2001 and 2006, left the party to contest with a BJP ticket from Jangipur parliamentary constituency. Khatun had, however, lost to Trinamool Congress during the 2011 and 2016 Assembly elections. Chatterjee alleged that the BJP is trying to influence the functioning of the Election Commission to function in a partial manner. “I have never seen earlier in Bengal that seven officers at the Inspector level are being removed just before the polls. The BJP knows very well that they will not win a single seat and in frustration, they are trying to use the Commission to do such things,” he said.last_img read more

Blood test can help diagnose preeclampsia

first_imgA simple blood test can help diagnose a common but potentially fatal pregnancy complication – pre-eclampsia, finds a study published in The Lancet journal. During the study, by measuring the concentration of placental growth factor (PlGF) in a woman’s blood, doctors were able to diagnose pre-eclampsia two days sooner on average. “We knew monitoring PlGF was an accurate way to help detect the condition but were unsure whether making this tool available to clinicians would lead to better care for women. Now we know that it does,” said lead author Lucy Chappell from King’s College London. Also Read – Add new books to your shelfPre-eclampsia, a condition in pregnancy characterised by high blood pressure, sometimes with fluid retention and proteinuria, can cause damage to vital organs, fits and can be fatal for the woman and baby, if left untreated. Globally, 100 women die due to pre-eclampsia every day. “For the last hundred years, we have diagnosed pre-eclampsia by measuring blood pressure and checking for protein in a woman’s urine. These are relatively imprecise and often quite subjective,” Chappell noted. Also Read – Over 2 hours screen time daily will make your kids impulsiveFor the recenlty conducted study, the research team studied 1,035 women with suspected pre-eclampsia from 11 maternity units across the UK. They were randomly assigned to two groups — one had their PlGF test results made available to their clinical team, the other did not. The PlGF testing was shown to reduce the average time to diagnose pre-eclampsia from four to two days and serious complications before birth (such as eclampsia, stroke, and maternal death) to four per cent from five per cent. There was no change in the likelihood of complications for the baby, the age at which babies were delivered prematurely or whether they were admitted to a neonatal unit, the researchers said.last_img read more
