Sensors, Vol. 19, Pages 4651: An Internet of Things (IoT) Application on Volcano Monitoring Sensors doi: 10.3390/s19214651 Authors: Shadia Awadallah David Moure Pedro Torres-González In the last few years, there has been a huge interest in the Internet of Things (hereinafter IoT) field. Among the large number of IoT technologies, the low-power wide-area network (hereinafter LPWAN) has emerged providing low power, low data-rate communication over long distances, enabling battery-operated devices to operate for long time periods. This paper introduces an application of long-range (hereinafter LoRa) technology, one of the most popular LPWANs, to volcanic surveillance. The first low-power and low-cost wireless network based on LoRa to monitor the soil temperature in thermal anomaly zones in volcanic areas has been developed. A total of eight thermometers (end devices) have been deployed on a Teide volcano in Tenerife (Canary Islands). In addition, a repeater device was developed to extend the network range when the gateway did not have a line of sight connection with the thermometers. Combining LoRa communication capabilities with microchip microcontrollers (end devices and repeater) and a Raspberry Pi board (gateway), three main milestones have been achieved: (i) extreme low-power consumption, (ii) real-time and proper temperature acquisition, and (iii) a reliable network operation. The first results are shown. These results provide enough quality for a proper...

In this work, novel hierarchical CoFe-LDH/NiCo2O4/Ni foam (CoFe-LDH/NCO/NF) core-shell nanowire arrays have been fabricated via a facile two-step strategy. The as-obtained nanocomposites were characterized by multiple methods, and their electrocata...

Diego ZuluagaYesterday, Joe Nocera penned an extraordinarycolumn expressing his bafflement at the Trump administration ’sdrive to release Fannie Mae and Freddie Mac, two firms that purchase and guarantee around half of single-family mortgages in the United States, from government conservatorship. Nocera argues against such a move, writing that “if it ain’t broke, don’t fix it . . . Fannie Mae and Freddie Mac ain’t broke.”The piece is disconcerting from start to finish. Nocera writes that Fannie and Freddie make the 30-year fixed-rate mortgage, a product common only in the U.S., possible ...

By SAURABH JHA, MD Slumdog TB No one knows who gave Rahul Roy tuberculosis. Roy’s charmed life as a successful trader involved traveling in his Mercedes C class between his apartment on the plush Nepean Sea Road in South Mumbai and offices in Bombay Stock Exchange. He cared little for Mumbai’s weather. He seldom rolled down his car windows – his ambient atmosphere, optimized for his comfort, rarely changed. Historically TB, or “consumption” as it was known, was a Bohemian malady; the chronic suffering produced a rhapsody which produced fine art. TB was fashionable in Victorian Britain...

(University of Maryland) New research reveals how a week in the dark rewires brain cell networks and changes hearing sensitivity in adult mice long after the optimal window for auditory learning has passed. With further study, cross-modal learning -- the manipulation of one sense to induce change in another sense -- could be used to help people with disabilities. For example, temporary sight deprivation might be used to help deaf and hearing-impaired people adapt to cochlear implants and hearing aids.

am AJ Abstract Acute angle closure is an emergent ophthalmic condition that develops as a result of an obstructed outflow of aqueous humour between the anterior and posterior chambers of the eye, leading to a sudden rise in intraocular pressure and secondary optic neuropathy if left untreated. The most common primary cause is a pupillary block in patients with pre-existing narrow angles, such as those who are long-sighted. However, awareness should be raised to identify secondary causes of angle closure, including the use of commonly prescribed medications. A detailed interrogation is essential to exclude other po...

Eyes are a worry aren’t they? I use mine a lot…but I have all these little floater things bobbing about, I see them when I use my PC, when I’m on the phone, when I’m outside on a sunny day, sitting reading, watching TV, playing guitar, taking photos, singing. All the time, actually. They’re always there. I was getting worried. Couple that to the need to find my glasses to read anything at all or look at an object any smaller than an inch across, and it’s all a bit worrying. So, nice to have an eye test where nothing truly untoward is revealed, just a slight and inevitably sliding into ...

By Pape Amadou Gaye, President and Chief Executive OfficerNovember 27, 2019Just 20 years ago, we could hardly imagine an AIDS-free generation. And the idea that poor countries would no longer rely on foreign aid to care for their people was inconceivable.But today, I believe both are in sight.The entire field of global health and development is shifting. Major funders, such as the U.S. government, are pushing ahead with an approach called localization, wherein countries manage their own foreign aid, mobilize their own public and private revenues, and eventually become self-reliant.This is what so many of us in nongo...

The sun is streaming through the curtains of a room that you have never seen before. You squint and rub your bloodshot eyes, as your hand reaches out to feel the prone body of the snoring person who a few hours earlier was a stranger. You notice your own naked body and wonder how the two of you spent the interceding time. You look at the floor next to the bed and see your clothes, strewn across the carpet, wine bottles and glasses, a few joints, and a line of cocaine on the dresser across the room. You slide out of bed, gather your belongings, hightail it to the bathroom and quickly get yourself street ready. Wondering ho...
