BACKGROUND Cardiopulmonary resuscitation (CPR) training has traditionally involved classroom-based courses or, more recently, home-based video self-instruction. These methods typically require preparation and purchase fee; which can dissuade many potential bystanders from receiving training. This study aimed to evaluate the effectiveness of teaching compression-only CPR to previously untrained ...

cumin (cuminum cyminum) is an annual suitable for the dry and semi-dry areas of iran. recently, farmers have chosen to plant cumin because it requires less water and growth time. however, at harvest time, the resistance of cumin seed to shatter is low and, if careful attention is not paid to this fact, a major portion of the crop can be lost. when the connection force of the seed decreases, see...

Visual search is the act of looking for—and hopefully finding—something that important or you need. You probably do this every day, like when must find your backpack before heading off to school. Sometimes can what are for just by using eyes, but other times also have use hands, a pencil in cluttered drawer. This called “interactive search” because it involves interacting with environment movin...

BACKGROUND High-resolution ultrasonography (HRUS) has been used to diagnose carpal tunnel syndrome (CTS) in recent years. However, the best diagnostic criterion and optimal cut-off value for HRUS remain controversial. METHODS This study enrolled 37 patients with idiopathic CTS (61 CTS hands) and 20 healthy subjects (40 normal hands). The subjects underwent nerve conduction studies along with ...

We investigate the real effects of mandatory climate-related disclosure by financial institutions on funding carbon-intensive industries. Our impact metric is amount invested into securities, bonds and stocks, issued fossil fuel companies. A French law, which came force in January 2016 aftermath Paris Agreement climate change, provides us with a quasi-natural experiment. The new regulation, uni...

We analyze “Bill-and-Keep” peering between two providers, where no money exchanges hands. We assume that each provider incurs costs from its traffic traversing its as well as the peer’s links, and compute the traffic levels in Nash equilibrium. We show that Nash strategies are not blind, i.e., they are neither pure hot-potato nor pure cold-potato strategies. Rather, the Nash strategies involve ...

Many problems that compilers want to solve are NP-Hard to solve optimally. Therefore, compilers authors typically use fast ad-hoc methods that strike a trade-off between good code quality and fast compile time. We investigated taking the decision on the trade-off out of the compiler author’s hands: based on profile information or static estimates, the compiler will tilt the balance in favour of...
