Satellite homes in Germany grew by 100,000 in the first half of this year to reach 17.6 million, despite analogue switch-off in April, according to figures compiled by satellite operator SES.According to SES’s Satellite Monitor, compiled by TNS Infratest, cable households fell by 300,000 to 17 million in the same period, while digital-terrestrial TV homes, boosted by switchover, reached two million by the mid-year point. IPTV homes reached 1.4 million, up 100,000 on the year-end figure.HD homes numbered 7.2 million, with 41% of satellite homes watching HD content.Ferdinand Kayser, chief commercial officer of SES, said: “These are outstanding results, especially for the transition of the analogue switch-off. Satellite is more popular than ever in Germany. The reason for our growth is simply that consumers value the benefits of linear satellite TV, combining unique picture quality with a large variety of channels. With new product initiatives like Sat IP, we will enable the reception of satellite TV on IP-based devices and thereby contribute to developing even further the capabilities of satellite, the most popular reception mode, for the benefit of all its current and future users.”
TV is on track to succeed the PC as the top platform for watching online video in the US, with TV viewing habits increasing as PC viewership declines, according to new research by Parks Associates.The research firm claims that in the first quarter of this year, US broadband users watched roughly three hours per week of online video on TV sets and PCs. However, for TV this was up from 2.3 hours per week in Q1 2013, while online viewing on PC is in “steady decline.”Parks’ report said that 81% of US broadband households watch video on TV, while 60% watch content on a computer, 31% on a smartphone and 28% on a tablet.The PC was the only platform to show “any significant decline in video viewing in the past year,” according to Parks.“Ultimately, consumers can more easily access online video options on a television than ever before,” said Brett Sappington, director of research, Parks Associates.“In addition to smart TVs, Blu-ray players, and game consoles, consumers are also buying streaming media players and devices such as Google’s Chromecast. Pay-TV providers are making a strong push to extend TV Everywhere to a variety of devices. These trends are converging to displace computer-based video consumption.”
Reviewed by Kate Anderton, B.Sc. (Editor)Dec 25 2018Galanin-like peptide (GALP) is a short peptide made up of 60 amino acid residues. This sequence is homologous across several species. The hypothalamic arcuate nucleus is the place where GALP is produced. GALP has diverse physiological effects such as the regulation of feeding, energy metabolism, and reproductive behavior. Neurons that contain GALP also express leptin receptors; at the same time these neurons form a network in the hypothalamus and these contain various amounts of peptides that regulate their feeding behavior.Related StoriesDiet and physical exercise do not reduce risk of gestational diabetesNew protein target for deadly ovarian cancerMetabolic enzyme tied to obesity and fatty liver diseaseNew research has shown that, GALP consists of anti-obesity action when it comes to its role in consumption of food and nutrition. After the administration of GALP into the lateral ventricle a decline in the respiratory quotient was also found. It is inferred that because of GALP, lipid metabolism could be accelerated. This is a recently discovered physiological action for this peptide.In this review, recent research about how GALP regulates feeding and energy metabolism has been summarized. Attention on the regulation mechanism of lipid metabolism that takes place in peripheral tissues through the autonomic nervous system is also given. The effectiveness of the nasal administration of GALP is also presented from a perspective of basic research and clinical application.Source: https://benthamscience.com/
May 9 2019Results from a new survey are the first to report a large discrepancy in patient’s knowledge of their cardiac implantable electronic device (CIED). The study reviewed patients’ overall knowledge of data from their devices as well as their perceptions on what is most important. Participants in this study have a strong desire to better understand their device and its data, with more guidance on battery life as the most important aspect for patients. The study is scheduled to be presented on Wednesday, May 8 at Heart Rhythm 2019, the Heart Rhythm Society’s 40th Annual Scientific Sessions.In the United States, cardiac arrhythmias impact an estimated 14.4 million patients (AHA). Today, CIEDs have evolved to be a prevalent treatment option for these patients, with more than 300,000 individuals receiving new CIED implants every year in the U.S. alone (Journal of American College of Cardiology). As new technology innovations emerge, patients have greater or unprecedented access to real-time data and information about their health from their devices. With advancing technology and increasing use of CIEDs, there is a need to better understand patients’ knowledge of their devices and their perceptions of what data elements are most important.The study initially screened 400 patients between July and December 2018 who attended an in-person device evaluation at the Cleveland Clinic outpatient clinic. The mean patient age was 62.9±12.8 years and 64 percent were male. Patients received a one-page questionnaire asking multiple choice questions in seven basic categories: type of CIED, original indication, functionality, manufacturer, number of active leads, estimated battery life, and number of shocks. Their answers were then compared to their interrogation report to assess accuracy. Patients were also asked to share what data would be most important to them as the device user. The importance of collaboration between clinicians, patients, industry and medical societies and how to manage access to data will be discussed during the inaugural Digital Summit on Wednesday, May 8.The Heart Rhythm Society’s 40th Annual Scientific Sessions convenes the finest clinicians, scientists, researchers, and innovators in the field of cardiac pacing and electrophysiology. More than 700 of the world’s most notable experts in cardiac rhythm management serve as faculty for over 250 educational sessions while more than 150 exhibitors showcase innovative products and services. Attendees can anticipate an enhanced experience with advanced learning formats and new opportunities for networking.

From this group, 62 percent agreed or strongly agreed that they were knowledgeable about their device, however, 84 percent missed at least one question. 48 percent of survey participants missed at least two questions about their device. Patients agreed or strongly agreed that they had a desire to have more information regarding each of the following: battery life (81 percent), activity level (76 percent), heart rate trend (73 percent) and ventricular arrhythmias (71 percent). The results of this study show a discrepancy in patients’ knowledge regarding their CIEDs and their wish to better understand the device. Our research uncovered a discrepancy between patients’ perception of their own knowledge of their devices and their actual knowledge about their device. While some patients have lived with these devices for years, our results show that there is still a general lack of knowledge. As digital health evolves, patients are able to access their own health data in real-time. By equipping device users to be active participants in their health, we hope they will be able to utilize their own data and be empowered to be more engaged in their care and live a healthier life.”Lead Author Divyang Patel, MD, Cleveland Clinic Despite the advancement in remote monitoring of CIEDs, up until recently it has been a process between clinicians and manufacturers, with patients on the receiving end. Now that patients have access to data in real-time, especially with the advancement of digital health technologies and increased use of smart devices, we need to help guide patients, clinicians, and manufacturers on how to make the most out of their information to help advance patient care and lead to positive outcomes. Our study is one of the first to give insight into the voice of the patient and what they desire to know. Now, the physician community along with device manufacturers and medical societies need to work together on a plan for optimal education and success.”Senior Author Khaldoun Tarakji, MD, MPH, FHRS, Cleveland Clinic Source:https://www.hrsonline.org/
As part of this exercise, AEMO forecasts the expected unserved energy in each region over the coming decade. Importantly, the base forecast only assumes “existing and committed projects.” Committed projects are essentially new generation assets that are fully financed. It also doesn’t include the temporary diesel generators installed in SA last summer, or the efforts to procure emergency reserves through the “Reliability and Emergency Reserve Trader”. These measures further reduce the likelihood of involuntary load shedding. Simply put, the statement forecasts the expected unserved energy over the next decade, if there is no further investment and the market operator fails to procure emergency reserves. Granted, this year’s report does shows an increased risk of unserved energy, compared with last year. In Victoria, this is primarily due to an increase in the forced outage rate assumptions for ageing brown coal plants.But the report also notes that AEMO expects the reliability standard to be maintained in NSW, Victoria and SA every year for the next decade, in the neutral scenario of its “Integrated System Plan” (ISP).The level of unserved energy in Victoria is forecast to fall to within the reliability standard. AEMO says this is due to the substantial volume of additional new intermittent generation developed in Victoria to meet the state’s renewable energy target, and additional interconnection called for within the ISP scenarios.What about blackouts?The media and politicians have seized on the “one-in-three chance of a blackout.” And it’s true: AEMO did indeed report a one-in-three chance of unserved energy in Victoria this summer.

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. Let’s have a look at what the reliability requirements actually are, and what AEMO’s Electricity Statement of Opportunities does and doesn’t say about the situation.Leaving aside the majority of blackouts due to faults or incidents, there are also some relatively rare times when there is simply not enough generation or transmission capacity to meet demand. This leads to “involuntary load shedding,” which is where certain customers’ energy demands go unmet – which they would experience as a blackout. This unmet energy demand is referred to as “unserved energy.”In the National Electricity Market, we have a reliability standard which specifies that expected unserved energy should not exceed 0.002% of total energy consumption in any region in any financial year. In other words, the system is expected to deliver at least 99.998% of the energy demanded by consumers. Historically, our grid has generally passed this standard with flying colours. Anyone who’s ever suffered the frustration of a power cut might ask why the reliability standard isn’t 100.000%. But building an infallible system – to the extent that it is even possible – would be hugely expensive. To do it, we would need enough capacity to supply every conceivable power demand scenario, no matter how outlandish. What does AEMO’s statement say?The annual Electricity Statement of Opportunities is intended to inform the market about when and where new generation is expected to be needed. This allows project developers to sharpen their pencils, develop and commit to new power projects. As the title of the report suggestions, it reveals opportunities for new investment. Provided by The Conversation Musk’s record-breaking battery officially launches in Australia But this figure is misleading when taken out of context. While there is a fair chance that some energy demand will go unserved, AEMO’s report also predicts that it will be below 0.002%, thus meeting the reliability standard.There is actually always a chance of some unserved energy. As discussed above, the aim isn’t to have no power cuts at all, but to keep them to an economically acceptable level. The fevered commentary misses this crucial nuance. But if it sells a few more newspapers, what’s the harm, right?Well, here’s the harm. Beating up the likelihood and significance of blackouts has real cost implications, as we have seen over the past decade through the gold-plating of “poles and wires.” Last month the Australian Competition and Consumer Commission released a report that specifically said “large cost increases in NSW and Queensland were due to the imposition of high network reliability standards on distributors in those states.” These high reliability standards were imposed after a series of minor blackouts in 2004-05.The Productivity Commission also addressed this issue in its 2013 review of network regulation, which blamed rising power bills on “political responses to isolated major blackouts, rather than systemic problems.” At a time when electricity prices are front-page news, unfounded hysteria about the risk of blackouts risks subjecting customers to yet more gold-plating. The community deserves to know the actual costs of improving our already highly reliable electricity system, rather than being fed fearful stories about the lights going out. This article was originally published on The Conversation. Read the original article. The Sydney Morning Herald reported “a one in three chance of power failure in Victoria unless immediate action is taken,” a prospect described by Victoria’s opposition energy spokesman David Southwick as “completely unacceptable”. In Adelaide, The Advertiser reported that South Australia faces a one-in-ten chance of forced blackouts this summer.Unfortunately, the commentary around AEMO’s annual statement has become increasingly misleading and irresponsible over time. The media reporting and public comments are tacitly or even explicitly advocating for the generation system to be “gold-plated,” which would come at great expense to consumers. Reliability and “unserved energy”Reliability, as defined in the National Electricity Market, is a measure of the ability of the grid and its associated electricity generation infrastructure to meet consumers’ demand.But the vast majority of power outages experienced by customers do not fall under this definition. Some 97% of blackouts are caused by faults or other incidents on the network, rather than a failure to install enough capacity to meet reliability standards. The blackouts that hit customers in New South Wales and Victoria over the weekend were perhaps inevitably described in parts of the media as a “dramatic reminder” to new Prime Minister Scott Morrison of the importance of addressing energy policy. But of course it is hard to legislate against lightning, which in this case triggered two interstate interconnector cables to trip and cause blackouts.
