first_imgNew Delhi : Murali Vijay and KL Rahul were dropped while Ravindra Jadeja returned to the squad as the Board of Control for Cricket in India (BCCI) on Tuesday announced the playing XI for the Boxing Day Test against Australia in Melbourne. Young Mayank Agarwal, who received his maiden Test call-up after Prithvi Shaw ruled out of the series due to injury, will make his debut. ODI specialist Rohit Sharma has also returned to the team after recovering from injury. The four-Test series is currently level at 1-1 and both teams would look to take an unassailable lead when they lock horns in the Boxing Day Test at Melbourne Cricket Ground.In the second Test, India paid the price of top-order failure. Both Vijay and Rahul have just scored 95 runs in their combined eight innings of the first two Tests in Adelaide and Perth. The duo, who literally failed to contribute decently, paid the price.Also Read | BCCI announces T20s, ODIs squads for New Zealand, Australia series, MS Dhoni makes returnDebutant Mayank Agarwal and Hanuma Vihari are expected to open the innings in the absence of regular opener Vijay and Rahul.

first_imgKiley said she believes overprescribing is a catalyst for the opioid crisis and hopes increased regulating efforts will be made. “To me, that’s like treating an addiction to vodka with one beer a day,” Kiley said in a Jan. 29 interview with The Two River Times. Updated totals published Jan. 30 by the Prosecutor’s Office revealed that in 2018 there were 215 recorded drug-related overdose deaths in the county, of which 183 deaths were related to heroin opiates – making last year the deadliest on record since the organization began tracking these incidences in 2012. “The opioid epidemic continues to devastate families and communities across our state,” Murphy said in a media release. “As we combat this crisis, it is critical that we use data-driven, evidence-based strategies to support individuals suffering from addiction and help them get on the path to recovery.” In July Murphy announced that New Jersey’s Medical Marijuana Program had grown by 10,000 patients since his administration took office at the start of 2018. These totals are a significant increase over the previous highs, recorded in 2016, of 164 drug-related overdose deaths, 150 of which were related to heroin opiates. • Supporting individuals on their path to and maintenance of recovery “Addiction is addiction. If you have an addictive personality it doesn’t really matter what the substance or activity is. Treating opioid addiction with marijuana might save a life, but I believe the individual will continue to be addicted. And if that marijuana high isn’t enough, they’ll eventually go back to opioids,” Kiley added. Additionally, Murphy announced four strategies for combatting the epidemic: Further, Medicaid will be building “Centers of Excellence” for opioid treatment at Rutgers New Jersey Medical School and Cooper Medical School of Rowan University. According to Carole Johnson, State Human Services commissioner, these centers will be used to support community-based clinicians in providing opioid addiction treatment. The dramatic increase was due to the six new additions to the program’s medical conditions list, including anxiety, migraines, Tourette’s syndrome, chronic pain related to musculoskeletal disorders and chronic visceral pain. One week after New Jersey Gov. Phil Murphy unveiled a series of initiatives he hopes will stem the troubling tide of the opioid epidemic, the Monmouth County Prosecutor’s Office (MCPO) offered a snapshot of a deadly 2018. • Increasing access to evidence-based prevention and treatment programs One of the Murphy administration’s efforts includes the addition of opioid addiction to the list of medical conditions covered by New Jersey’s expanding Medical Marijuana Program. Medicaid is also planning to launch a series of efforts to advance accessibility to MAT, including initiating the Office Based Addiction Treatment (OBAT) program, which will create new Medicaid reimbursement incentives for primary care providers to offer MAT for opioid addiction. Newly elected Monmouth County Freeholder Susan M. Kiley said treating opioid addiction with marijuana is something she opposes. “I’m angry about it because I believe a huge percentage of those suffering in this opioid crisis started because they went to see a physician,” Kiley said. “They go in to be treated for an illness or an injur y and get overprescribed. We’re talking about young kids all the way up to seniors. It has to stop, and stronger regulations and better tracking of prescriptions is a way to start.” Use disorder is linked to dependence, in which a user may feel symptoms of withdrawal when coming of f a particular substance. These efforts are part of a developing plan to battle the opioid epidemic and Murphy has already advanced $100 million from his 2019 budget to put toward the fight. To help advance these initiatives, Murphy said Medicaid will remove the requirement for prior authorization for Medication Assisted Treatment (MAT), which so often serves as an administrative barrier to life-saving treatment. • Building sound data systems and strengthening system-wide infrastructure for the addicted population Kiley, the Freeholder Board’s liaison to the County Health and Human Services Department, said she believes addiction is not always contingent on the product, but a user’s personality. • Delivering robust law enforcement to stem the supply of illicit drugs, while also supporting diversion programs Courtesy: Monmouth County Prosecutor’s Office Kiley said she disagrees with the commonly accepted sentiment that marijuana is not an addictive substance and, though it may not contain addictive properties, the National Institute on Drug Abuse indicates that marijuana use can lead to the development of use disorder.last_img read more

first_imgLike many other events this year, Raid the North Extreme was impacted by the heavy snowfall and late spring.“With 150% snowfall this year and the late melt, we had to make some last minute changes to the course just to deal with trails that were still under snow and check points along the water that were 100 meters off where they should be because the water’s so much higher,” said Race Director Geoff Langford. Even with course alterations, teams struggled with the terrain.“There was so much more water and snow than anticipated that it really slowed a lot of teams down. Because of all the moisture, bush has grown in heavier, there’s more deadfall that hasn’t been cleared yet…it slowed a lot of teams down for sure.”The NewZealand/Canadian team WildernessTraverse.com was awarded first place, while second went to Canadian team Wild Rose, and American team DART-Nuun-SportMulti placed third.Local team Kootenay Kaos did not finish the course on time.“The finish rate was a little lower than usual. We usually get half the teams finishing, and this year it was about a third.”Overall, the feedback from racers has been really positive, and for many teams, the terrain was more than they anticipated.“They love the area. Most of them were a little surprised at how rugged it was. They got to enjoy over 100 000 feet of elevation gained and lost throughout the week. Most teams weren’t really prepared for it. It surprised them and challenged them, and blew them away.” Geoff Langford, Race Director and Course Designer, has organized the race since its inauguration in 1999 and mixed business with pleasure in order to focus on the 2011 race. “I was moving personally to somewhere that I wanted to live, and I wanted to put on this race wherever that was. From past visits to the area and knowing the region, I decided this was the best place in Canada to put on a race and into live. I love it here.” Previous versions of the race have been held from Newfoundland to the Yukon. The Kootenays presented its own set of unique challenges.  “The biggest challenge was actually selecting what to include in the race course. There was just so many challenging areas, so many highlights, so many cool things I wanted to include that it was more work to pick out what I wanted to use. Usually I’m just trying to find enough!” Typically friendly locals were reluctant to help with course design while guarding their secret wilderness hideouts and mountain sweet spots. “It was an interesting process putting it together.Asking locals ‘what are the great spots, what are the hidden gems, what are the secret, cool spots…’ People aren’t that keen to share that stuff. I had to discover a lot of it for myself.”Langford persevered with the course design and chose landmarks and locations that were highlights for all the teams from start to finish.They started on Meadow Mountain and “when you’re standing in that meadow up there you get a 270 degree view of snow-capped mountains. It’s breathtaking, and I think it really set the pace for what they expected for the rest of the race.”“They got to bike the Seven Summits, which I think was a real highlight for most of them.  Trekking through Valhalla Park was definitely the highlight for everyone. Not a lot of locals even manage to get there.” Although Raid the North is the marquee event for Frontier Adventure Sports & Training, the company offers eight, 12, and 36 hour adventure races throughout the country. The next race is 12 hours through the Muskoka wilderness in Ontario.Langford plans to continue to take advantage of the Kootenay wilderness by offering an annual 36 hour race.“Over the next month or two we’ll be working with sponsors and see if we can pull it off. I’m pretty optimistic.”For more details on race coverage and Raid the North,visit the organization’s site.last_img read more

first_img(Visited 491 times, 1 visits today)FacebookTwitterPinterestSave分享0 To know the vast improbabilities, and yet to leap over them with imaginary stories – that’s deceiving the public.Suppose an unlucky soul has to win a thousand powerball lotteries to pay his debts, but tells his creditors, “Well, it could happen.” Does a person like that deserve credit? And yet our federal space agency, NASA, fully aware of the difficulties of getting life to ’emerge’ by chance, talks like that. Let’s see what an entry in NASA’s Astrobiology Magazine admits about the difficulties they face:Life relies on the intricately folded amino acid chains known as proteins for practically every chemical task. Proteins catalyze chemical reactions throughout the cell, stitch RNA strands together, transport molecules around the cell and control what enters and leaves through the membrane. A modern cell cannot be a cell without them.However, proteins pose a problem for scientists who study the beginnings of life. Present-day proteins have had the benefit of billions of years of evolution. They are highly specialized and, compared to most molecules, they are enormous. The odds of such lengthy amino acid chains forming “out of the blue” in life’s primordial soup are beyond astronomical.“Beyond astronomical.” Think of it: astronomical odds are hard enough, but ‘beyond astronomical’ is, for all practical purposes, miraculous. It’s nice of NASA to admit that, but the admission doesn’t go far enough. One must visualize analogies like “The Amoeba’s Journey” from Illustra Media’s film Origin to even begin to grasp just how ‘beyond astronomical’ this ‘problem’ is. Illustra’s animation is only for a 150-amino-acid protein, much smaller than the average length of proteins in living cells. Can anyone think of a phrase for “beyond ‘beyond astronomical’”? That’s the challenge for those who insist on limiting their scientific explanations to chance and natural law.Our unlucky soul, before being tossed out the creditor’s office door (or window), might try some fast talking. “Actually, I can imagine some scenarios where I might actually win a thousand powerballs, but I would have to start simple. I can show this in a computer simulation. In my simulation, after I win the first one, I could use my winnings to buy more tickets for the second one. The second winning ticket might be naturally selected to win the third, and the fourth, and so on. Eventually I could get to my goal step by step. Looking back after billions of years of lottery evolution, it would look like a miracle, but it was really very natural. If you just will loan me more money, I can demonstrate this with my computer simulation.” This is exactly how NASA leaps over ‘beyond astronomical’ in a single bound.To help answer these questions, Andrew Pohorille, senior astrobiologist at the NASA Ames Research Center, and his colleagues have been running computer simulations of hypothetical ancient proteins. In a paper published in the journal Life in June 2017, they detailed two unconventional protein structures that could have been useful in primordial cells.While most modern proteins are rigid, specialist molecules with complex structures, these hypothetical early proteins would have been more flexible, but less efficient and precise, Pohorille argues.“These were the handymen of proteins,” Pohorille says. “In the beginning evolution did not require the high level of precision that we have now.”Can anyone doubt that the allusion to Genesis, “in the beginning,” represents a religious speculation equivalent to a miracle? There are numerous problems with this fast-talking excuse:Do “computer simulations” substitute for physical reality? No.Do “hypothetical ancient proteins” substitute for empirical evidence in the lab? No.Do “unconventional protein structures that could have been useful” substitute for real protein structures? No.Do speculations about proteins being more flexible amount to laboratory evidence? No.Do “flexible, but less efficient and precise” proteins escape error catastrophe? No.Do any proteins we know of get built without ribosomes? No.Do naturally-produced amino acids come in single-handed forms? No.Did evolution ever not require a high level of precision? No.Does calling a protein a “handyman” endow it with powers to create handy things? No.The storyteller deserves to be tossed out onto the curb before he opens his mouth, but NASA lets him talk. Pohorille endows his “strange, new protein” that is “very unlike proteins seen in modern cells” with seemingly magical powers. Like the Cat-in-the-Hat, his magical protein cleans up all the problems just as the parents walk in the door.This strange, new protein could do an important job and remain functional despite mutations, and it was small enough that something like it could have plausibly formed on the early Earth without billions of years of evolutionary fine-tuning.Pohorille continues, talking about how ‘short’ proteins can do all kinds of wonderful things. He fails to acknowledge, though, that it can only do these wonderful things in cells with thousands of other large proteins. The most basic ‘primordial’ cell must have genetic codes, machinery to read them and convert those codes into proteins, and machines to capture nutrients and convert substances into energy. That energy must be directed for metabolism and many other functional requirements. See the basic needs of a ‘simple’ cell in Illustra’s animation, “How to Build a Cell.” His perhapsimaybecouldness index skyrocketing, Pohorille chatters on:To form a stable tunnel through the membrane, these proteins have to form a stable tunnel through the membrane that can be opened and closed to molecular traffic. The cell membrane is 18 to 20 amino acids wide; anything smaller won’t span the entire barrier. However, when Pohorille and his colleagues simulated the structures of channels formed by a 16-amino-acid-long protein called antiamoebin, which is presumably too small to span the cell membrane, they found that clusters of these short proteins could form channels of a different nature. These channels were unstable, constantly shifting, and would sometimes close and then reopen, but they were large enough to let potassium and chloride ions through, as well as water molecules.This speculation fails to recognize the role of transport proteins: to control what goes in and out.  An unguided pore through a membrane is likely to swamp the cell with useless or toxic substances, by the laws of osmosis. It would have no ‘selectivity filter’ to go against the concentration gradient. Nor would it have energy from ATP, requiring the complex ATP synthase motors, to power the channels. As a result, potassium and chloride ions and water would go the wrong way through the membrane, and the ‘primordial’ cell would quickly die. But even in his wildest imagination, envisioning short proteins with “candidate structures” able to perform a few tasks, Pohorille knows better. He knows he wouldn’t have life.“Many people think of the origin of life as a problem in organic chemistry: how to make this or how to make that,” says Pohorille. “I could give you all these molecules, and you will still not be able to make life. The essence of life is that you have a number of functions, and these functions are capable of working in concert.”This is like the debtor admitting in the end that there’s no way he can pay. And yet NASA willingly shells out more dough for him. We learn in the last sentence, “Pohorille’s work was supported by NASA Astrobiology through the Exobiology & Evolutionary Biology Program and performed at the NASA Ames Research Center and the Pittsburgh Supercomputer Center.”That’s your taxpayer dollars at work, folks. Are you angry yet? It is ‘beyond astronomical’ to imagine why anyone would give this program a penny. These storytellers deserve something far worse: shame and reproach by the scientists who respect real empirical evidence for things. Maybe even jail time for promoting fake science with taxpayer funds.last_img read more

first_imgOnce the system is complete, a total of 10 new baggage reclaim carousels will be in operation, four of which are 90-metre baggage carousels specifically designed for the massive new generation aircraft such as the Airbus A380. SAinfo reporter ‘On track for 2010’ “Members of the public collecting incoming international passengers should take heed of the new signage in order to orientate themselves,” OR Tambo GM Chris Hlekane said in a statement by Airports Company South Africa (Acsa) this week. Once arriving passengers have been processed through customs, they are received into a new international arrivals public concourse, which is two-and-a-half times larger than the previous international arrivals hall. Acsa will also open the central terminal building’s retail facility, which is designed to link directly into the domestic terminal’s retail level, next month. “The opening of the 18 000 square meter space will also boast some retail facilities including a post office, cellular phone shops and foreign exchange services, with various eateries expected to open by December this year,” the statement read. The rail line will be elevated above the airport precinct, over the upper roadway system, and will be directly connected to the central terminal building. The project will be fully complete in December next year following the complete installation of the new baggage management system at international arrivals. Further, the construction of the airport’s Gautrain Station has been completed and the shell has been handed over to Bombela for final finishing, making the station the first to be completed. The mezzanine levels of the central terminal building will offer retail facilities and basements will be in use for services and baggage handling.center_img The new R2.3-billion central terminal building at OR Tambo International airport outside Johannesburg opened this week, with passengers now being processed through new international arrivals facilities, which including a more user-friendly customs control process. Fully-linked terminals The international and domestic terminals at the OR Tambo airport will be fully linked by April 2009, when the central terminal building’s departures facility becomes operational. The new departures hall will contain 75 new check-in counters, effectively linking the airport’s international and domestic check-in facilities. “Passengers and meeters and greeters will also be assisted by Acsa’s new i-Help Agents – identifiable by their orange waist coasts – located along the new route for any other queries.” At this point, passengers will be able to enjoy a fully complete multi-level terminal building located between the international and domestic terminals. In line with existing airport flow, departures activity will predominantly be on the upper level with arrivals activity on the ground level. 4 September 2008 “[The] opening is an important milestone as it marks the start of the completion of the final piece in our massive infrastructure development programme in the run-up to 2010,” Hlekane said. “It gives me great pleasure to declare that OR Tambo is on track for 2010 and beyond.” Would you like to use this article in your publication or on your website?

first_imgRelated Posts Apple just announced some major additions to its iBooks e-reader application. Most importantly, iBooks users can now read their PDF files in iBooks. PDF documents will get their own bookshelf in the application. In addition, iBooks users will now be able to write notes within the app and create bookmarks with a single click instead of having to highlight a word to create a bookmark. These new features will be available later this year. Obviously, most of this feature – and especially notes – should have been in the original iBooks app. It’s good to see that Apple is finally adding this functionality, which is already available in almost every other e-reader application on the market today.2.5 eBooks Per iPadWith regards to eBooks on the iPad, Steve Jobs also announced that Apple has sold about 2.5 books per iPad since the launch. That, of course, is far behind Apple’s numbers for iPad apps (users have installed about 17 apps per device) – though 2.5 books is not a bad number, especially given that most books are retailing for at least $10. Sadly, Apple did not disclose how many of these books were paid downloads. In total, iPad owners downloaded 5 million books so far. Jobs also stressed that publishers are telling Apple that iBooks now accounts for 22% of their e-book sales. frederic lardinois Why Tech Companies Need Simpler Terms of Servic… A Web Developer’s New Best Friend is the AI Wai… Top Reasons to Go With Managed WordPress Hosting Tags:#Apple#web Image credit: gdgt 8 Best WordPress Hosting Solutions on the Marketlast_img read more

first_imgHe always starts by talking about how no one wanted to buy the delectable fish that was called Patagonian toothfish. But when they changed the name to Chilean Sea Bass, it became a big hit. Words matter.So, zero energy homes it is. I’m OK with that, even if it’s a bit inaccurate (because all homes use energy).The definitionIn the introduction of the DOE report, they write, “A zero energy building (ZEB) produces enough renewable energy to meet its own annual energy consumption requirements, thereby reducing the use of non-renewable energy in the building sector.” As I wrote in my article on the 4 possible definitions, things get a little squirrelly when you start talking about how you’d measure the energy produced and consumed. And a couple of the definitions aren’t actually based on energy; one uses energy costs and the other uses emissions.The two big contenders, though, are whether you base the definition on site energy or source energy. First, let’s just define what these two things are.Site energy – This is the energy used on-site, as measured at the meter. For electricity, just look at the kilowatt-hours you get billed for; for gas, the therms or BTUs.Source energy – This is the energy used on-site plus the energy that went into getting that energy onto the site. For electricity, it’s the kilowatt-hours you get billed for plus the kilowatt-hours of energy that are “consumed in the extraction, processing and transport of primary fuels such as coal, oil and natural gas; energy losses in thermal combustion in power generation plants; and energy losses in transmission and distribution to the building site.” That quote is from the DOE report, A Common Definition for Zero Energy Buildings, released this month.Now, how do you qualify a zero energy building? Using the site energy definition, every kilowatt-hour (kWh) of electricity you import to the site has to be offset by an equal number of kilowatt-hours produced on-site and exported to the grid. Likewise, if you burn natural gas on-site for heat, for example, all the BTUs you burn would have to be offset with an equivalent number of BTUs produced in the renewable energy production system on-site.Using the source energy definition, you have to account for the energy used at the source and in transmission and distribution. Doing the calculations for source energy is a bit less straightforward when the home uses fuels other than electricity.In the new DOE report, they came down on the side of source energy. Here’s their fleshed out definition:An energy-efficient building where, on a source energy basis, the actual annual delivered energy is less than or equal to the on-site renewable exported energy.They also put forth an expanded definition of source energy:Source Energy: Site energy plus the energy consumed in the extraction, processing and transport of primary fuels such as coal, oil and natural gas; energy losses in thermal combustion in power generation plants; and energy losses in transmission and distribution to the building site.I say it’s expanded because they’re including the embodied energy of the fuel burned at the power plant.In addition to this definition, they also define something new called Renewable Energy Certificates (RECs), which they define as “tradable instruments that can be used to meet voluntary renewable energy targets.”If you want to learn more about all this, go to the DOE page on this new Zero Energy Building definition and download the 22 page pdf. They show how to do the calculations, qualify zero energy buildings, and use Renewable Energy Certificates.One of the best things about this paper is this qualifying factor from page 10:The designation Zero Energy Building (ZEB) should be used only for buildings that have demonstrated through actual annual measurements that the delivered energy is less than or equal to the on-site renewable exported energy.It doesn’t matter how it models. What matters is how it actually performs. That’s not exactly a common way of thinking in Washington, D.C., where saying one thing and doing another is a way of life.Calculating the zero energy balanceOf course, you have to define the site boundary, which could be the perimeter of the building or the property line. Any energy that crosses the boundary is counted as delivered or exported site energy.I wrote about these calculations a little bit in my article on the four definitions of zero energy use, but it wasn’t as clear as it could have been. This time I think you’ll get it.The DOE is going with source energy as the basis for zero energy buildings, so let’s see how that works. The first thing you need to know is how to go from site energy to source energy. For that, all you do is multiply by the appropriate conversion factor. The table shown in Image #3 (at the bottom of the page) is given in that latest DOE document on zero energy buildings and come originally from ASHRAE standard 105.What confuses a lot of people is that second line. For example, if a home uses 10,000 kWh per year of electricity delivered to the home, it takes 31,500 kWh of source energy to make that happen. So you might think that if you put photovoltaic modules on your roof, you’d need to export 31,500 kWh of electricity to the grid to offset the source energy of the electricity delivered.Not true! Every kWh that you send to the grid really offsets 3.15 kWh of source energy because that kWh can be delivered to another home instead of the electricity from the power plant, with its 3.15 kWh of source energy. Hence the second line in the table above. Imported and exported electricity both get multiplied by the same conversion factor.Using a fuel like natural gas on-site can be confusing, too, but if you just use the table above, it’s pretty easy. Let’s put some numbers in an example:Imported energy A few weeks ago, I wrote about whether homes that produce as much energy as they use should be called net zero energy or zero net energy homes. Several readers offered up another choice: zero energy homes.I’ve also written in the past about four different ways to define net zero energy (the term I’ve preferred). Now, the U.S. Department of Energy (DOE) has weighed in on both of these debates. Do you know what they decided?The nameThe name of the DOE report is called A Common Definition for Zero Energy Buildings. That gives away their name preference, which they’ve actually been using for a while. They dropped the “net” altogether and assume people will be able to figure out what it means. I’m OK with that. The scientist and grammarian in me wants a more precise term, but I get it.Sam Rashkin, the Chief Architect in the DOE’s Building Technologies Office, has been presenting on clearing up our language in the energy efficiency community for the past couple of years. I just heard him again recently in Chicago, where he gave the closing keynote speech at the 10th annual North American Passive House Conference. Electricity6,000 kWh3.1518,900 kWh TypeSite EnergyFactorSource Energy To qualify as a zero energy building, this home would have to offset 20,177 kWh of source energy. Because exported electricity gets multiplied by the 3.15 conversion factor for electricity, that gives us:E x 3.15 = 20,177 kWhE = 20,177 kWh ÷ 3.15 = 6,406 kWhWhat that means is that you’ve got to produce 6,000 kWh of electricity on-site (renewable only – diesel generators don’t count) to offset the imported electricity and another 406 kWh to offset the natural gas use.Make sense?If you’ve got other energy types or fuels in the mix, you do the same thing. Just pick the appropriate source energy conversion factors from the table and calculate the imported and exported energy numbers.

They had an excellent win against the Serbian pair of Nenad Zimonjic and Anna Ivanovic to book a place in the quarterfinal.India’s campaign in men’s singles and doubles and women’s singles also didn’t last long.Wild card entrant Somdev Devvarman, India sole representative in the singles, suffered a first round exit to Finland’s Jarko Nieminen in a rain-affected encounter.The second to go out was the women’s doubles pair of Sania and Rushmi Chakarvarthi, who were knocked out by Chia-Jung Chuang and Su-Wei Hsieh of Chinese Taipei in the opening round.The men’s doubles pair of Mahesh Bhupathi and Rohan Bopanna, who had revolted against the All India Tennis Association (AITA) for asking them to pair with Paes, went down tamely 3-6, 4-6 to Frenchman Richard Gasquet and Julien Benneteau in the second round.But Paes, playing with a young partner Vishnu Vardhan, held his head high after they lost to the second seeded French pair of Jo-Wilfried Tsonga and Michael Llodra in an evenly fought second round match.advertisementlast_img read more
