Share Facebook Twitter Google + LinkedIn Pinterest The title of this article is also the theme for the 2015 National Farm Safety and Health Week, observed September 20-26. The theme reminds local and rural communities that agriculture is one of the most dangerous industries in the U.S. This industry, which includes farming, forestry and fishing, accounts for nearly 500 fatalities each year (according to the U.S. Department of Labor, 2013).As the theme suggests, practicing safety is something we should do, not something we merely say. While it is great to profess our attitude for safety, it is better for us to practice it everyday in our daily actions. When safety is a part of our workplace routine, it becomes a way of life. Employees and employers work together to create a culture for safety.Having this culture for safety, brings to consideration an ancient proverb that safety professionals have adapted over time. It questions whether Safety is an end of a means, or a means to an end. Safety is an end of a meansIn other words, working all of our lives to be safe when we retire, is working towards a goal. This practice can also be noticed when companies post, rather prominently outside of their entrances, the number of work days with no recordable injuries. These companies may be working towards a specific goal where there is a bonus or incentive for workers to reach the end of a week, month, or year with no injuries. These are two examples where safety is viewed as the end of a means. Safety is a means to an endOn the other hand, when safety is a means to an end, it is simply a way we get to the endpoint. In this manner, Safety is likely a lifestyle. It is a method we use along the way. It is a practice we do every day, and in every season.The year 2015 marks the 71st year for the U.S. to observe National Safety and Health Week. In 1944, President Franklin D. Roosevelt set aside the third week of September as a time to celebrate the farmer and remind agricultural workers of safety practices needed to get them through another harvest season, and another year.The Ohio State University Agricultural Safety and Health Program promotes this commemorative week, but also has materials available throughout the year. A variety of outreach resources are developed for different farm operations, large or small, and a wide range of workforce ages, including safety messages for children or visitors who may not work on the farm. Many of these resources are provided at no cost on the website. Training programs are also available for agricultural groups and businesses looking for specific workplace issues. A monthly newsletter is published each month called Ag S.T.A.T. This online publication shares short announcements of upcoming safety events, as well as delivers short safety messages for that particular time of year.All of these materials are available through the OSU Ag Safety Program website: www.agsafety.osu.edu or Facebook at OSU Ag Safety and Health. The OSU staff will also be at Farm Science Review conducting grain safety demonstrations in OSU Central during Farm Safety Week. Stop by and visit their team to answer your specific questions. Farming is a lifestyle, and so is workplace safety. The goal is to help every farm worker and farm family member get to the end of the year in the safest manner possible.
Second seed Rafael Nadal beat Juan Martin del Potro 7-5 6-7 4-6 6-4 6-4 in the quarters of Wimbledon to set-up a high-octane clash with world No. 21 Novak Djokovic in the semi-finals on Friday.Just 90 minutes after defending champion Roger Federer was sensationally knocked out by South African Kevin Anderson on Wednesday, it seemed as if the grasscourt major would lose its top two seeds as Argentine Del Potro took a two-sets-to-one lead.It was not as if Nadal was playing badly as he had lost only nine points on serve before heading into the ninth game of the second set.But just before that game started, Federer’s shock demise was flashed up on the giant on-court scoreboard and it was as if that threw the Spaniard off his stride and he fluffed his lines to drop his serve.After Nadal squandered four set points in the third set tiebreak, with a double fault on one of them, Del Potro made him pay as he pounced on his first chance to raise the prospect of another astonishing upset on day nine of the championships.But the second seed stayed alive by taking the fourth set before the gripping drama continued in an electrifying deciding set in which both players were left diving after volleys and slipping over as they chased after blinding winners.Nadal ended the four hour and 48 minute thriller with a backhand volley winner past a lunging Del Potro who ended the contest lying flat on his stomach.advertisementDJOKOVIC EASES PAST NISHIKORIEarlier, Djokovic shrugged off a second-set slump to reach a Grand Slam semifinal for the first time since 2016 by beating Kei Nishikori 6-3, 3-6, 6-2, 6-2.Djokovic wrested back the momentum for good after coming from 0-40 down at 2-2 in the third set to hold serve, and then breaking his Japanese opponent in the next game.The three-time Wimbledon champion was broken in the opening game of the fourth set, but won the next four games and broke again to clinch victory.Djokovic looked in control in the first set. But he grew frustrated after failing to capitalize on three straight break points in the third game of the second set and was given a code violation after slamming his racket into the ground.When Nishikori then bounced his own racket against the court in the fourth set without being given a warning, Djokovic yelled out “double standards” toward the umpire’s chair drawing boos from the Centre Court crowd.That didn’t seem to affect his focus, though, and neither did a time violation he was given when serving at 4-2, 30-30 in the fourth set.Djokovic secured that game with a forehand winner, then saved two game points on Nishikori’s serve before converting his first match point with a forehand down the line.He next faces two-time champion Rafael Nadal or fifth-seeded Juan Martin del Potro in his first Grand Slam semifinal since the 2016 U.S. Open.(With inputs from agencies)

Last year the city agreed to pay Fifth Avenue 33 million dollars for the lease, if the voters approved a hotel tax increase that was to happen in 2018.The city was to make three payments this year, the first being 9.4 million, but the vote was delayed until 2020.The land is owned by the port and was leased to 5th avenue in 2010. Five years later, the city wanted to buy the lease from 5th Avenue for 14 million dollars, but defaulted on the payment and the lease reverted back to 5th avenue.The 14 million dollars it would have cost the taxpayers to get the lease in 2015, is now 33 million in 2019.

Wanted felon holes up in SUV, prompting police standoff SAN DIEGO (KUSI) – A wanted felon believed to be armed with a gun holed up Thursday inside an SUV outside a motel near Imperial Beach when officers tried to arrest him, prompting an hours-long standoff.National City police requested backup from their counterparts in the city of San Diego about 10:15 a.m. while trying to get the suspect into custody in the 1000 block of Outer Road in Palm City, near Hollister Street and just east of Interstate 5, SDPD Sgt. Michael Stirk said.The man, whose identity was not immediately available, also apparently had been involved in a hit-and-run traffic accident, the sergeant said. Where and when that crash occurred was unclear.Officers with pistols and rifles drawn surrounded the SUV in which the suspect — who reportedly at some point had made a comment about committing “suicide by cop” — was barricaded as negotiators tried to persuade him to surrender peaceably.The stalemate was ongoing in the early afternoon, Stirk said.

The content is provided for information purposes only. Three teams find a way to measure frequencies with far better precision than previous techniques As Rechtsman notes, optical sensors are used in a variety of applications that involve very slight mechanical vibrations or changes in temperature. They are also used when working with nanoparticles or in the analysis of biomolecules. All such sensors have a single problem, however—their performance is limited by the strength of the perturbations under study. In this new effort, both research teams sought to overcome this limitation by coupling modes of light, allowing them to coalesce—this occurs in places called “exceptional points,” and they only arise in what are known as Hermitian systems. In such systems, prior research has shown, photon loss is a main feature, as opposed to conventional systems in which the opposite is true. In either case, the result is increased sensitivity, which, of course, translates to more precision.In the first effort, the researchers connected three ring-shaped sensors together and then added gold heating elements beneath them to fine tune the sensors and to emulate perturbations. In the second effort, the researchers used just one ring-shaped sensor but sent light around it in both directions (both clockwise and counterclockwise) at the same time to cause coalescence. Then, they used a fiber tip to fine tune the sensor and a second tip to cause perturbations.Both techniques come with a trade-off, Rechtsman notes, between fine-tuning and sensitivity, and there remains the question of whether either or both can be modified to achieve even higher sensitivities. Citation: Two ways to improve optical sensing using different resonator techniques (2017, August 10) retrieved 18 August 2019 from https://phys.org/news/2017-08-ways-optical-resonator-techniques.html Structures called optical resonators trap light at certain frequencies. When the environment of such a resonator is perturbed, these frequencies shift, which allows optical resonators to be used as sensors. a, Hodaei et al. report a sensor that consists of three ring-shaped resonators that are coupled (red arrows). The authors use gold heating elements both to precisely tune the sensor and to emulate perturbations. b, By contrast, Chen et al. use a single toroidal resonator, and couple light that travels in clockwise (blue arrow) and anticlockwise (yellow arrow) directions. The authors use two fibre tips to tune the sensor and another type of tip to introduce perturbations. c, In conventional sensors, the shift in frequency caused by a perturbation is directly proportional to the strength of the perturbation (grey line). Hodaei et al. and Chen et al. demonstrate that the frequency shift in their sensing devices scales with the cube root (red line) or square root (blue line) of the perturbation strength, respectively. This leads to a dramatic improvement in the scaling of sensitivity of such sensors in comparison to conventional devices. Credit: Mikael C. Rechtsman, Nature 548, 161–162 (10 August 2017) doi:10.1038/548161a (Phys.org)—Two independent teams working on research aimed at improving optical sensing have used techniques that involve coupling two or more modes of light such that their modes and their corresponding frequencies coalesce, resulting in more sensitivity. In the first effort, a team from Washington University in St. Lois and Otto-von-Guericke University Magdeburg, in Germany, connected three traditional sensors for more precise tuning. In the second effort, a team from the University of Central Florida and Michigan Technological University used just one resonator but coupled light traveling in both directions around it. Both teams have published papers describing their efforts and results in the journal Nature. Mikael Rechtsman with the Pennsylvania State University offers a News & Views piece outlining optical sensing techniques and the work done by the two teams in the same journal issue. Journal information: Nature © 2017 Phys.org More information: 1. Weijian Chen et al. Exceptional points enhance sensing in an optical microcavity, Nature (2017). DOI: 10.1038/nature23281AbstractSensors play an important part in many aspects of daily life such as infrared sensors in home security systems, particle sensors for environmental monitoring and motion sensors in mobile phones. High-quality optical microcavities are prime candidates for sensing applications because of their ability to enhance light–matter interactions in a very confined volume. Examples of such devices include mechanical transducers, magnetometers, single-particle absorption spectrometers3, and microcavity sensors for sizing single particles and detecting nanometre-scale objects such as single nanoparticles and atomic ions. Traditionally, a very small perturbation near an optical microcavity introduces either a change in the linewidth or a frequency shift or splitting of a resonance that is proportional to the strength of the perturbation. Here we demonstrate an alternative sensing scheme, by which the sensitivity of microcavities can be enhanced when operated at non-Hermitian spectral degeneracies known as exceptional points. In our experiments, we use two nanoscale scatterers to tune a whispering-gallery-mode micro-toroid cavity, in which light propagates along a concave surface by continuous total internal reflection, in a precise and controlled manner to exceptional points. A target nanoscale object that subsequently enters the evanescent field of the cavity perturbs the system from its exceptional point, leading to frequency splitting. Owing to the complex-square-root topology near an exceptional point, this frequency splitting scales as the square root of the perturbation strength and is therefore larger (for sufficiently small perturbations) than the splitting observed in traditional non-exceptional-point sensing schemes. Our demonstration of exceptional-point-enhanced sensitivity paves the way for sensors with unprecedented sensitivity.2. Hossein Hodaei et al. Enhanced sensitivity at higher-order exceptional points, Nature (2017). DOI: 10.1038/nature23280AbstractNon-Hermitian degeneracies, also known as exceptional points, have recently emerged as a new way to engineer the response of open physical systems, that is, those that interact with the environment. They correspond to points in parameter space at which the eigenvalues of the underlying system and the corresponding eigenvectors simultaneously coalesce1, 2, 3. In optics, the abrupt nature of the phase transitions that are encountered around exceptional points has been shown to lead to many intriguing phenomena, such as loss-induced transparency4, unidirectional invisibility5, 6, band merging7, 8, topological chirality9, 10 and laser mode selectivity11, 12. Recently, it has been shown that the bifurcation properties of second-order non-Hermitian degeneracies can provide a means of enhancing the sensitivity (frequency shifts) of resonant optical structures to external perturbations13. Of particular interest is the use of even higher-order exceptional points (greater than second order), which in principle could further amplify the effect of perturbations, leading to even greater sensitivity. Although a growing number of theoretical studies have been devoted to such higher-order degeneracies14, 15, 16, their experimental demonstration in the optical domain has so far remained elusive. Here we report the observation of higher-order exceptional points in a coupled cavity arrangement—specifically, a ternary, parity–time-symmetric photonic laser molecule—with a carefully tailored gain–loss distribution. We study the system in the spectral domain and find that the frequency response associated with this system follows a cube-root dependence on induced perturbations in the refractive index. Our work paves the way for utilizing non-Hermitian degeneracies in fields including photonics, optomechanics10, microwaves9 and atomic physics17, 18. Explore further
