 HOW TO EXTEND LITHIUM-ION BATTERY LIFESPAN Many of the recommended practices are terkait to the three main variables that impact baterai health: temperature, state of charge, and current. slot game online terpercaya di indonesia Here are some general guidelines from the researchers to maximize lithium-ion baterai lifetime, along with a few specific recommendations from manufacturers: Avoid temperature extremes, both high and low, when using or storing lithium-ion batteries. Elevated temperatures can accelerate degradation of almost every baterai component and can lead to significant safety risks, including fire or explosion. If a netbook or cellphone is noticeably hot while it's charging, unplug it. Minimize exposure to low temperatures, especially when charging. For electric vehicles, nearly all manufacturers include warnings about high temperatures in their owner manuals. Some of them advise parking in the shade and keeping the vehicle socketged in during hot weather, thereby al

 Reopening university and college campuses with primarily in-person classes is associated with a significant increase in cases of COVID-19 in the counties where the schools are located, according to a new study. slot game online terpercaya di indonesia "THE TOTAL SPIKE ATTRIBUTED TO FACE-TO-FACE CAMPUS REOPENINGS ACCOUNTS FOR NEARLY 6% TO 7% OF ALL CASES IN THE US DURING THIS TIME." "Consequently, we are able to predict between 1,000 and 5,000 additional cases per day due to colleges reopening for face-to-face instruction, with our best estimate being somewhere around 3,000 cases per day or around 21,000 cases per week," says coauthor Anirban Basu, professor of health economics and director of the CHOICE Institute at the University of Washington School of Pharmacy. IN-PERSON CLASS AND COVID SPIKES More specifically, campuses with mostly in-person instruction contributed to increases in COVID-19 cases in their county by 0.024 cases per 1,000 residents. And, when stud

 The findings also raise doubts about the traditional cost-benefit analyses used by states that have, or are, implementing cellphone-driving bans as a way to promote safety. slot game online terpercaya di indonesia "Using a cellphone while driving may be distracting, but it does not lead to higher jatuh risk in the seting we examined," says Saurabh Bhargava, assistant professor of social and decision sciences at Carnegie Mellon University. "While our findings may strike many as counterintuitive, our results are precise enough to statistically call into question the effects typically found in the academic literature. Our study differs from most prior work in that it leverages a naturally occurring experiment in a real-world context." Do cellphone bans work? For the study, Bhargava and the London School of Economics and Political Science's Vikram S. Pathania examined calling and jatuh data from 2002 to 2005, a period when most cellphone carriers offered pricing pl

 A crystal that can form a paper-like sheet just three atoms thick could potentially create electronics that would be as light and flexible as fibers. This could lead to flexible electronic materials and perhaps make it possible to weave cellphones or GPS, for example, into a shirt. slot game online terpercaya di indonesia Computer simulations show that this crystalline lattice has the remarkable ability to behave like a switch: it can be mechanically pulled and pushed, back and forth, between two different atomic structures—one that conducts electricity well, the other that does not. "Think of it like flicking a light switch on and off," says Karel-Alexander Duerloo, a Stanford University engineering graduate student and first author of an article in Nature Communications. So far this discovery only exists as a computer simulation. But coauthor and tim leader Evan Reed, an assistant professor of materials science and engineering, hopes the work will inspire experimental scie

 Choosing smart phone situations and personalizing phones with appeals and designs may expose a great deal about a person's society, as well as increase accessory to devices. slot game online terpercaya di indonesia In a research study on society and smart phone personalization, scientists found that individuals from Eastern societies have the tendency to be more motivated to change the appearance and sound of their smart phones compared to individuals in Western nations, says S. Shyam Sundar. "Individuals that live in collectivist societies are often more other-directed," says Sundar, a teacher of interactions at Penn Specify. "They wish to know how others might appearance at them as well as appearance to others as a way of affecting their own habits." AMERICANS AND SOUTH KOREANS The scientists gave American and Southern Oriental trainees studies on how they personalized their smart phones and asked them how they perceived their social identification and initia
