Jason Morgan, who set a new national record in the discus in 2015, is looking forward to being even better in 2016 and perhaps even win an Olympic medal in Rio this summer.He has reason to be optimistic. Training has been going well, he is working with a team of coaches, and best of all, he has a shoe contract with apparel manufacturer Puma that is expected to run until the end of his career.In other words, things are looking up for the 33-year-old 2014 Commonwealth Games bronze medallist, who in June last year set a national record of 68.19 metres in Pearl, Mississippi.It was the second best throw in the world for 2015.”I am working a part-time job while I train and at this moment, training is going hard and well. I have a set workout plan and different cycles for the season. I also have a couple of great coaches that will assist me on the road to the Rio Olympic Games,” he said. “I have great support and a management team, and it’s a blessing to have Puma as my sponsor.”training in preparationFor the past few years, Morgan has endured great financial difficulty while training in preparation to represent Jamaica. Earnings from his job, plus some financial support from the Jamaica Athletic Administrative Association (JAAA), were not enough to allow him to take care of his family, train, cover medical expenses and travelling to competition.He believes his work ethic and affable personality helped land him the Puma contract, revealing that officials there have told him that they have always admired his will power and hard work, as well as his character.The deal he signed with Puma last December now allows him greater freedom to focus on his preparation for what could be his last Olympic Games.”It’s like a dream come true,” said Morgan of the shoe contract. “They have supported Jamaica’s track and field and the world’s best athletes. They will assist me on the rest of my journey. It’s a blessing to be able to be part of a pioneer brand, and I will continue to inspire and break down barriers, and give young and old people hope to believe in themselves, no matter what the journey.”
Charles Boyle and Pat O’Donnell before they set off on their long sojourn to witness Donegal defeating Dublin in the All-Ireland semi-final.COUNTDOWN TO CROKER: Donegal ‘Superfan’ Charles Boyle is in a race against time to secure a coveted ticket to the All-Ireland final against Kerry.Charles travelled a staggering 16,738km from Australia for the semi-final clash with Dublin.And when Jim McGuinness’ men toppled the Dubs, the Carrickfin man vowed to stay on for the final on September 21st. Charles outside Croke Park before the All-Ireland semi-final victory with Dublin.But now the 26 years old, who is an electrician based in Perth, is finding it impossible to nail down a golden pass for the ticket.His decision to extend his stay for the All-Ireland final also means Charles has sacrificed spending Christmas with his family here in Donegal, but it could all be in vain.Charles told Donegal Daily, “I’m in the same boat as many other Donegal supporters regarding tickets, but it’s looking very unlikely I’ll be able to get a ticket for the match now.“I’m not a club member because I’m living in Australia, and obviously the club membership has increased and the demand for tickets is even greater than two years ago. “My cousin got me a ticket for the All-Ireland final two years ago, but even he’s having trouble getting one for himself this time around.”Charles revealed it was a difficult decision to sacrifice Christmas with his family, but said All-Irelands don’t come around too often and you don’t know when they’ll be in another one.“I’ll be gutted if I can’t get one, as I’ve sacrificed spending Christmas with my family in order to extend my stay in Ireland.“It was a difficult decision, but I couldn’t bare the thought of returning to Australia with Donegal in the All-Ireland final.“You never know when Donegal will be in another All-Ireland final, and you can’t take it for granted they’ll be there every couple of years. “Hopefully someone somewhere will be able to help me get a ticket, but I appreciate there are other Donegal supporters in the same boat as me.His commitment to Donegal can’t be questioned, Charles flew back from a family wedding in Spain on the Saturday night before the All-Ireland final with Mayo.Charles was also very critical of the ticket allocation awarded to Donegal for the match, and criticized the GAA hierarchy for their ticket distribution process.“The amount of tickets given to Donegal and Kerry is a joke, it’s a disgrace that genuine supporters of both counties are overlooked in order to ensure the corporate side of things are looked after. “Donegal and Kerry should be given 35,000 tickets each, and the other 12,000 should be distributed amongst the other counties and corporate entities thereafter, it shouldn’t be the other way about,” he fumed.SUPERFAN CHARLES’ RACE AGAINST TIME FOR ALL-IRELAND FINAL TICKET was last modified: September 11th, 2014 by StephenShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window)Tags:AustraliaCharles BoyledonegalGAAJim McGuinnesssuperfan
OAKLAND — No criminal charges will be filed against Toronto Raptor’s president of basketball operations Masai Ujiri, who was accused of pushing and striking an Alameda County sheriff’s deputy after Game 6 of the NBA Finals in June, an Alameda District Attorney spokeswoman said Tuesday.“The District Attorney’s Office has determined that no criminal charges will be filed in the matter,” said spokeswoman Teresa Drenick. “However, Mr. Ujiri attended a meeting with the District Attorney’s Office …
(Visited 311 times, 1 visits today)FacebookTwitterPinterestSave分享0 There’s 100 times less of a radioactive element on the ocean floor than expected.According to commonly accepted theory, heavy elements are cooked inside stars and distributed via supernova explosions. One particular unstable isotope, Plutonium-244 with a half-life of 81 million years, should be a good tracer of supernova explosions in the earth’s vicinity. Since the earth is believed to have formed 4.5 billion years ago, any primordial Pu-244 should be long gone. New Pu-244 should have come from supernovae since earth’s birth. But there’s a problem. PhysOrg starts an article with the rumble of a paradigm shaking:Scientists plumbing the depths of the ocean have made a surprise finding that could change the way we understand supernovae, exploding stars way beyond our solar system.What happened? Dr. Anton Wallner of Australian National University and 12 colleagues went looking for Pu-244 on the ocean floor, thinking there should be some specks from supernova explosions during the past 100 million years. Earth should receive a sprinkling of this isotope because, according to theory, abundances of heavy elements should reach a steady state in interstellar dust.“We’ve analysed galactic dust from the last 25 million years that has settled on the ocean and found there is much less of the heavy elements such as plutonium and uranium than we expected.“The findings are at odds with current theories of supernovae, in which some of the materials essential for human life, such as iron, potassium and iodine are created and distributed throughout space….“We found 100 times less plutonium-244 than we expected,” Dr Wallner said.Scratching his head, Wallner wondered if theories of nucleosynthesis of heavy elements are wrong. Maybe it takes the collision of neutron stars to form this isotope. Where do large radioisotopes come from?The fact that these heavy elements like plutonium were present, and uranium and thorium are still present on earth suggests that such an explosive event must have happened close to the earth around the time it formed, said Dr Wallner.“Radioactive elements in our planet such as uranium and thorium provide much of the heat that drives continental movement, perhaps other planets don’t have the same heat engine inside them,” he said.His findings not only question nucleosynthesis, therefore, but add an additional constraint on habitability. Without the radiogenic heat to drive plate tectonics, it is unlikely a planet would be suitable for complex life. Wallner et al.‘s study is published in Nature Communications.We offer this astro-geo-physical tidbit to individuals who may wish to explore the implications. One possibility Wallner did not think to consider was whether the earth is younger than he assumes.
Editor’s Note: This is one of a series of blog posts by David Goodyear describing the construction of his new home in Flatrock, Newfoundland, the first in the province built to the Passive House standard. You’ll find his complete blog here. It is now May. The weather is shaping up, and after a long, cold winter the ground is starting to thaw. Old Man Winter did give me one thing this year: a lot of time to think. I have been thinking mainly about food security and accessing more locally grown food. We had a successful harvest last year and a cellar to store all of our garden goodies to eat during the winter. It’s hard to believe that we are still eating crisp and sweet Newfoundland carrots that were pulled from the earth last November!RELATED ARTICLESA Farmstead of the Future in GeorgiaA Vision of the Future Takes Shape in ParisAdopting a Green LifestyleA Slow Living Summit in Brattleboro, Vermont The wonders of having a root cellar have really amazed me. Did you know that you can store a cabbage (with its roots attached) in an underground root cellar for a really long time? I didn’t. The last cabbage that I pulled out of our underground lair was 3 1/2 months old (see the photo below). A few leaves had dried a bit and formed a protective layer around the cabbage. After peeling, it emerged as a perfectly clean, crisp garden-grown cabbage waiting for the perfect slaw on a pulled pork sandwich! This cabbage has been in a root cellar for 3 1/2 months, but thanks to low temperatures and high humidity it’s in perfect condition. Photo: David Goodyear Storage in the cellar at high humidity and low temperature (but above freezing) is really about creating a space where vegetables can stay barely alive by passively using energy from the massive heat sink of the earth. After the last harvest I realized that I now have the infrastructure in place to grow and store even more than I previously thought. It would be great if I could grow more–more varieties of cold climate vegetables that have good storage characteristics, short season vegetables that lend themselves well to canning, and greens–lots and lots of greens! So, greens are a problem. We have a short growing season. The growing season can be extended by using conventional greenhouses and cold frames. However, green vegetables are hard to store for long periods of time. They won’t last in a root cellar. However, plants like radicchio and Belgian endive (chicory family) grow as a root, similar to a carrot, which can be harvested, stored in a cellar, and then forced to grow tightly packed heads months later. Cabbages are easy and versatile and a regular part of traditional Newfoundland cooking. These are great options, and nutritious ones, but not really that green. To obtain greens you need a longer growing season, or some way to extend it. A root cellar effectively extends growing to four seasons by keeping subterranean vegetables alive, but greens need light. So the answer is obvious: A greenhouse is in order. Insulation is the key to performance A greenhouse can have have many forms depending on how it will be used and where it is located. A simple polyethylene hoop house could extend the season here for a few weeks in spring and fall. However, I want to minimize the gap in our growing seasons significantly. Glazings and air leakage are where most heat is lost here. So a structure with decent glazing R-values (for a greenhouse) and good air tightness is a must. The structure needs thermal mass in order to cruise through significant temperature swings in both winter and summer. Passive solar greenhouse design is just using a lot of common sense. Insulate where the sun is not able to enter. Insulation is key to performance. North, east, and west walls all should be highly insulated. To Passive House standards? Obviously not. This article was compact and informative and provided some basic design criteria for an extended season greenhouse. The sweet spot appears to be somewhere around R-20 walls and R-2 glazings. R-2 glazings are expensive, so I would opt for locally available R-1.5 double-panes but use a homemade insulated curtain (R-1) at night to increase energy savings. I am looking at about 220 square feet of glazing. A couple of quick calculations can easily show that going beyond R-20 and decreasing thermal bridging is a waste of time and money. Sinking money into a heat source is probably a better investment. Since this kind of greenhouse really only needs to keep vegetables alive through the cold months, a low-grade heat source such as a climate battery (ground source heat exchanger), or a point source heater, such as a compost pile could produce all the energy necessary to maintain temperatures above 0ºC, or freezing. Location: A south-facing hillside The location for our greenhouse is absolutely perfect–a south-facing hillside. This will allow us to put a foundation into the hill and use the natural shape to berm the north wall to between 4 and 5 feet. The east wall will be mostly bermed while the west and south walls will only be partially buried. This works out great because I can build a knee wall on the south side with anywhere from 2 to 4 feet of vertical glazing and also have glazing on the roof. Vertical glazing works well in the winter because the sun is low in the sky (about 20º above the horizon). A variety of glazing angles could work but ideally one would try to set the glazing angle to be perpendicular to the incident sunlight in the winter. Of course, this is also a matter of design, aesthetics, and whether it can be easily built. Our frost depth here is about 30 inches, so the foundation will need some insulation. There is no doubt about that, but with the earth-bermed walls, R-8 may be enough. Ideally it would be best if our design was easily constructed so I could do most of the work without needing too much help. This is a major driving factor here. Making headway is much easier when you can be self sufficient. Each design under consideration has been modeled in HOT2000 and is showing anywhere from 700 to 1000 kWh to heat during the winter in order to maintain 5ºC. It is less than 500 kWh if I just want to keep it above freezing. All of this being said, the foundation for each design is the same. Onwards and upwards! Extending the growing season Placing a greenhouse on top of the ground is like changing the climate above the ground where it sits, which in turn affects the average yearly ground temperature at the greenhouse location. I seem to recall reading somewhere that the length of the growing season in an uninsulated greenhouse is similar to the length of the outdoor growing season one climate zone south. For us, the length of our growing season in Climate Zone 6a in a greenhouse would be about the same as the length of the outdoor growing season in Climate Zone 5. The effect is a combination of things. First, the temperature of the greenhouse will typically be greater than outside, and second, some of the heat collected by the greenhouse is conducted into the ground inside the greenhouse, providing thermal mass that resists freezing. Below grade, R-8 wing insulation will extend out from the structure about 8 feet all the way around. The thermal resistance of the ground is highly variable and dependent on its many individual components. In our case, R-8 insulation will be equivalent to about 2 1/2 feet of earth. Once the earth is bermed on the north side, the bottom of the greenhouse will effectively be at about 8 feet. The south side will effectively be at between 4 and 5 feet, so the thermal mass below the greenhouse is definitely protected from the winter frost and will provide a huge thermal mass for cruising through the winter months. As a protective measure, a vapor barrier around the foundation will run out to the perimeter drain like an umbrella, preventing water from stripping away heat from the thermal mass. Making an underground heat battery Storing heat for use at a later time is not easy. Heat moves–always from hot to cold. But this can be used to our advantage. The greenhouse is really just a large solar collector. Most people who own a greenhouse know that it can get so hot that plants will die, so the heat must be vented. Although our greenhouse will have vents for use as needed, I want to increase the sphere of influence of the underground thermal bubble by charging the ground like a climate battery. A climate battery is really just a system of ducts below ground. You use a fan to push hot air from the peak of the greenhouse underground. The air loses heat to the ground and cools before it exits back into the greenhouse. My plan is to insulate the ground partially above the battery so that the heat conducts mainly downwards into the cool earth rather than back into the greenhouse. As the greenhouse begins to cool in the winter, it becomes a heat sink and heat from the ground will move towards it and keep it from freezing inside. This idea is not new and has many names: climate battery, GAHT, SHCS, etc. These are a little different than what people call annualized geo-solar. Once the system is up and running it will behave like a combination of a climate battery and an annualized geo-solar system. After a lot of back-breaking work, the site for the greenhouse was ready for construction. Photo: David Goodyear Site work was a grueling task. I spent my spare time in April clearing trees, windfall, stumps, twigs, and brush, and then chipping all the piles of debris. Luckily I have several cubic meters of wood chips that I can use for composting later. So the hard work paid off with a clear site and lots of chips. Components of the underground thermal storage system are in place. Photo: David Goodyear Once the site was ready I marked out the foundation, perimeter drain, and the location of the climate battery. It took about a day to install all the components (see the photo above), and another day to tamp the area for the concrete footing. Ready for footings!
