OAKLAND — A return to the Coliseum may have been all Mike Fiers needed to get back on track.Starting his second Opening Day in nearly the span of a week, Fiers made up for the poor first one in Japan by looking more like the pitcher who piloted the A’s 2018 playoff run in Thursday’s 4-0 win over the Los Angeles Angels.Command was an issue for Fiers in his first start and still somewhat of a problem against the Angels — he walked three batters and hit another. But leaving the Tokyo Dome, where …
Something strange happened in the E ring of Saturn last January. The incident is forcing scientists to conclude the ring cannot be very old. The E ring is the broad, extended ring that extends from Mimas to Rhea (click here for diagram), over three times as broad as the main ring system but much more diffuse. It reaches its maximum density at the orbit of Enceladus. This fact leads Cassini scientists to anticipate finding ice geysers on the moon when Cassini flies by it at close range next March. Dr. Don Shemansky reported at a news conference today that the Cassini UVIS instrument (ultraviolet imaging spectrograph) measured a surge in atomic oxygen coming from the E ring. Measurements beginning in December showed a sudden rise in oxygen in late January that dissipated by April. Apparently a collision in the ring ionized water molecules among the icy particles. Electrons in the plasma sheet around Enceladus quickly recombine with these ions, forming neutral atoms which are swept into the vacuum, eating away the ring. With evident surprise, he told the press that this one incident resulted in a mass loss equal to the total mass of micron-sized particles in the entire E ring. Extrapolating backward, assuming this event was not atypical, he calculated an upper limit of 100 million years for the lifetime of the ring. Dr. Larry Esposito said later in private conversation that the incident may have been caused by two large bodies colliding within the ring. He estimates such an event could occur once every 4 to 10 years; if so, it was a fortuitous circumstance for Cassini, at the start of its 4 year tour, to witness the event. Whatever happened, it was abrupt, severe, and short-lived. In the press conference Q&A, Dr. Shemansky, noting the bland expressions in the audience, said he must have understated the “spectacular nature” of this discovery. So he repeated it, with emphasis: the mass quantity lost in the event was equal to the total mass of all the micron-size particles in the entire E ring – in just four months. A press release and image can be found at the Cassini website.Update 07/11/2006: the source of the oxygen is the moon Enceladus, which is erupting water out of its south pole. See the 07/11/2006 and 11/28/2005 reports.This discovery adds to others that have led most ring scientists to conclude that planetary rings must be young. A hundred million years sounds like a long time, but is a mere blink of an eye compared to the assumed age of the solar system (about one fiftieth of 4.5 billion years). Notice that they did not say the ring is 100 million years old, but that it could not be older than that. To believe it is much younger is reasonable in light of the evidence; it would seem a stretch to imagine an E ring many orders of magnitude thicker millions of years ago. Today the E ring is tenuous and mostly composed of fine particles. A much more massive E ring would seem to correspond to an epoch with more impactors flying around, resulting in exponentially faster erosion. This age limit is not a problem for those who believe the solar system was created recently. It is only a difficulty, an anomaly, a surprise, a puzzle for those locked into a mindset that the earth, and life, evolved slowly over vast periods of time.(Visited 13 times, 1 visits today)FacebookTwitterPinterestSave分享0
South Africa’s economy was built on its mineral wealth. Now mining houses are re-investing in the communities that have grown up around their operations. (Image: Brand SA) • Focus on African resources at Mining Indaba • Machel, Blair head to South Africa for Mining Indaba • Working towards sustainable mining • Robots that can save miners’ lives • Johannesburg – from mining camp to big city Sulaiman PhilipMining – and its unparalleled influence on the South African economy – began with the discovery of the Eureka Diamond in 1867. But it was the discovery of a rich seam of gold in 1886 on the Rand that turned the South African economy from largely agricultural to the richest gold mining area in the world within a decade.Fortunes were made and lost on the golden Rand. For the majority of the large pool of labour that travelled to the mining camps that became towns and then cities, however, the mines were just a means to an end. The poorer end of the white labour market saw the riches of the mines as a way to supplement income from farming or to pay tax bills. For African men, labouring on the mines was the fastest way to earn enough to pay lobola and buy a piece of land to farm.Mining is the foundation on which the South African economy was built. Between 1860 and 1910 as a mining-centred economy evolved and old farming and trading traditions died, mining houses used their wealth and political power to create a migrant labour force through the need to pay new taxes or the appropriation of land.Then, in the 1970s Anglo American, through its Urban Foundation, began upgrading education and infrastructure in the townships. And American companies operating in South Africa during apartheid were subject to the Sullivan Code. Devised in 1977, it was a set of principles that compelled American companies to run their South African operations using American human rights and social justice principles.By 1994, as the old political and economic system died, working conditions on the mines for the migrant labour put mining houses in the harsh glare of the resurgent, politically powerful union movement. To the unions, these philanthropic acts were window dressing that did little to change the conditions on mines or alleviate the suffering of communities once operations stopped. Dark villageNaledi Trust is a village of 34 households close to Kroonstad in Free State. Since 2009, the community has been without electricity because it owes Eskom R47 000 – an insignificant amount to the big mining houses, but it might as well be R4-billion as far as the community is concerned.Mohapeloa Komane, the principal of Lovedale Primary School in Naledi, grumbled that lack of electricity made it difficult for her charges to study. “For instance, some homework to do with weather forecasts was difficult to do because they needed to have watched the forecasts on television. But because they had no electricity, they could not get to watch television,” she told the Weekly newspaper.Now, thanks to a world-first project led by Anglo American and its partner, Ballard Power Systems, the lights are on in Naledi. The mining house and the Canadian company are testing a power cell that converts fuel into electricity.Part Anglo corporate social investment (CSI) project and part pilot project, the fuel cells in Naledi use platinum, methanol and hydrogen to generate 15kW of power used for cooking, lighting, televisions and to run the fridges donated by Anglo American Platinum.There are business advantages for Anglo – a cheap, constant power supply not dependent on Eskom – but the Naledi test is also a major programme in the mining house’s CSI unit. If the 12-month test is successful, Anglo will begin to roll out the technology to the 600 000 South African households that Eskom does not reach.For Anglo, if the test phase is successful, the project could lead to the development of a high-tech manufacturing business. A new rural electrification industry means jobs in manufacturing, design and installation maintenance which will support and sustain Anglo mining jobs.But none of this matters to Doko Petrus Mvundle, a 90-year-old resident of Naledi, who simply sees a brighter future for his community: “This electricity will change our lives. I have always hoped that one day the lives of our children and grandchildren will be better than ours.”A 2014 report measuring the performance of listed companies when it came to their spending on CSI found that the mining industry spent the most on CSI programmes. In total, the industry invested R3.9-billion a year on programmes, most of it in communities around their operations. Next Generation’s Reanna Rossouw, a management consultancy, says that companies have started to look at CSI as an investment rather than as a hand-out. “The days of ‘feel good’ programmes are over. Boards want to know how CSI will benefit business.”Tough economic times and the regulatory environment mean companies are looking to measure the effect of their programmes not just in terms of return on investment for shareholders but also in terms of effect on beneficiary communities. Sustainable businessThe mining industry has embraced a new way of doing business. “Organisations have entered a new era of doing business in communities to whom products and services are sold and on whom mining companies depend for future sustainability and profitability. CSI forms an integral part of the sustainable organisation of the future.”Across the group, including its Chairman’s Fund, Anglo American spent R643-million on CSI projects, part of the R50-billion the private sector spends on CSI programmes a year, in 2014. Like other mining houses, the money was invested in projects in education, business development, health, community development, art and culture, and sports development.For Norman Mbazima, the chairman of the fund, the company is investing in the future of the country and the company by helping to build dynamic, enabled communities. By harnessing the company’s strengths and the country’s resources, Anglo American is helping South Africans take control of their lives. “We’re committed to not only being a good corporate citizen but to making a genuine difference in the communities surrounding our operations, and in South African society as a whole. In all our efforts as a company, we work towards delivering sustainable value that makes a real difference now and for the future.”We commit ourselves to building a humane, equitable and caring global society, cognisant of the need for human dignity for all.The South African government enacted legislation after 1994 requiring CSI-linked support for socio-economic development. Legislation like 2002’s Mineral and Petroleum Resources Development Act changed the environment in which mines operate. It vested ownership of the nation’s mineral wealth in the state an introduced obligations for mining companies that sought prospecting rights or mining licences.After the 2002 World Summit on Sustainable Development in Johannesburg, a framework was developed to strengthen the partnership between the government and the private sector. The JPOI (Johannesburg Plan of Implementation) called on industry to contribute towards sustainable development. For mining houses this meant that sustainable development influenced all aspects of their operations, from prospecting to post-closure.After 2002, the International Council on Mining and Metals’ stated objective became a “need to contribute first and foremost towards improvement of the quality of life of the communities in which [mines] operate”.
The only reason they’re not already used on every stick-built house is inertia. “We’ve been doing it this way for 30 years and it’s never been a problem.” If you’re a builder and worried about trying something new, check out Matt Risinger’s video about standard framing versus advanced framing.The exterior walls in a typical house are 25% framing. Wood has an R-value of about 1 per inch. Most insulation is close to 4 per inch. Using these advanced framing techniques will reduce the amount of wood in those walls and increase the insulation.It’s time to get over the inertia. These things are easy, easy, easy. Your house won’t fall down. Instead, your house will be better. Allison Bailes of Decatur, Georgia, is a speaker, writer, building science consultant, and the author of the Energy Vanguard Blog. You can follow him on Twitter at @EnergyVanguard. Most new homes in North America are built with sticks. The early home builders used bigger pieces of wood — timbers — and when the smaller dimensional lumber that we use so much today hit the market, they scoffed at those new-fangled little woody things, calling them sticks. Now our home construction industry is full of people who do stick building and the home you live is most likely stick-built. And sadly, many of the techniques used to build many of those homes are the same used before we started insulating them.Before insulation became widespread, it didn’t matter if you put extra wood in your walls. In fact, many builders still think more wood is better. But when your insulation goes into the cavities between framing members, every extra bit of wood means less insulation. That means more heat loss in winter and more heat gain in summer because wood has an R-value less than a third that of most insulation. (Putting all the insulation on the outside is better, but that’s more expensive and not likely to happen on a wide scale in the residential market.)The good news is there are some simple ways to improve the framing and get more insulation without compromising the structural stability of the home. Here are three I think ought to be used on every stick-built home.Ladder T-wallsThis one is a no-brainer. When an interior wall intersects an exterior wall, the standard practice is to use three studs to complete the T-wall. The photo above shows what that looks like.[Image credit: U.S. Department of Energy]The oriented strand board (OSB) sheathing you see in the photo above will get covered with insulation. The space between those two studs in the exterior wall, however, won’t get any insulation. There’s no way to get it there. (Well, you could drill holes and try to spray foam in there, but spraying foam in a closed cavity risks blowing out the wall or leaving voids. Plus, few builders would take the time to do that.)One easy solution is the ladder T-wall. The diagram at right shows what it looks like.Rather than vertical studs, you take some of your scrap wood and run it across horizontally. You put the wide side against the T-wall stud so you have space in the back to insulate that cavity. It’s beautiful! You save wood and get a better-insulated house, too.The photo above is from the North Central Georgia affiliate of Habitat for Humanity. We work with them and are always impressed with their ability to implement stuff like this.Here’s what it looks like in real life (right).It’s got 1-by deadwood for drywall and what is essentially fireblocking through the cavity.Of course, there are variations of advanced framing at T-walls. Here’s one that a client of ours used a few years ago (right). RELATED ARTICLESThe Pros and Cons of Advanced FramingGBA Encyclopedia: Efficient Framing Fine Homebuilding: ”The Future of Framing Is Here” by Joseph Lstiburek The advanced framing alternative is to use three studs but leaves an opening to get insulation back into the corner, like this (right).It’s usually called a California corner here in the Southeast. I’m not sure what it’s called in California. Maybe just a corner? That DOE fact sheet I mentioned above also shows how to do a two-stud corner. Here’s the diagram (right).It uses less wood and gives you even more space for insulation. Check out the fact sheet for more details on that. The natural solution here is to throw some insulation in the gap. You can do it easily with rigid foam board. If you don’t like foam, you can use mineral wool or something else. Just get some insulation in there. Otherwise, you’ve got a thermal bridge that wastes your heating and cooling dollars and could create other problems, like making your mean radiant temperature uncomfortably cold in winter or hot in summer.The image at right (from the same U.S. Dept. of Energy document on advanced framing as the ladder T-wall image) illustrates how it works.Going a step further, you can get more reduction of thermal bridging at headers by sizing them properly or not using them at all. A lot of framers will use the same size header in every opening of the house. But different openings have different loads to transmit. And some have no load. In those cases, you can make the header smaller or eliminate it, leaving room for even more insulation.Too easy not to useThese three advanced framing techniques for walls in stick-built homes are too easy not to use. In fact, some people will look at these and dispute their being called “advanced framing” at all. But in the Southeastern U.S. and some other regions, plenty of builders still haven’t adopted these three techniques. California corners and two-stud cornersThis is similar to the T-wall problem. The standard practice uses three studs and blocks off the corner so you can’t insulate it. Here’s what it looks like (right). Insulated headersHeaders abound in stick-built homes. They carry the load when you can’t put in studs at the regular spacing, as is the case where you have doors and windows. They’re often made with two pieces of bigger wood, like 2x10s, but they have a gap. In a 2×4 wall, two 2x10s on edge are 3″ thick. The wall is 3.5″ thick. In a typical home, that extra half inch is wasted. In a 2×6 wall, you’re wasting 2.5”.

Many of us have experienced adventure on our way to a Touch Football tournament…a flat tyre while taking that “shortcut” your mates suggested was a good idea…the after-effects of a dodgy chiko roll at a late night roadhouse…or having your luggage end up on the other side of the country. Next time you face a hurdle or two in getting to your next game, spare a thought for the Ramingining team that competed at the recent Northern Territory Touch Football Titles. For those that don’t know, Ramingining is about 530km east of Darwin in East Arnhem Land, and if you want to drive to the NT capital, the best you’ll do is seven or eight hours dodging potholes all the way to the city. Two teachers from the Ramingining School – Cam Adams and Joseph Smith – came up with the idea to get a team together from the Indigenous community, and prepare them to compete at the NT Titles. The fact none of the boys had ever played the game before (except Cam, a former Barbarians, WA and Cook Islands representative player) did nothing to curb the enthusiasm that Cam and Joseph had for the task of competing. The plan eventually went before another teacher – Geoff Guymer – who helped draft a letter to the East Arnhem Shire and the office of Malindirri McCarthy (MP for Arnhem Land). The Shire granted support, while Ms McCarthy contributed some of her own money to help the team. The NT Touch budget also assisted, and from there, Cam, Joseph and the team never looked back. Ever had trouble getting players committed to training? It wasn’t a problem with these boys, so long as they had a way to get there for the daily 4pm sessions. “Joseph and I literally had to drive around the community in our cars to pick up the boys for training”, said Cam. “A lot of people get used to having an oval to train on – you know – a flat surface, good grass cover. For us, it was just an open space – the surface wasn’t level, and we had anthills, potholes and tree stumps to watch out for.” Training didn’t always go well, as Smith explains. “We had a public holiday the other week (in late April). The shop was shut, so it meant most of the boys hadn’t had their usual sugar fix, so they were flat and didn’t have much energy for training.” No doubt plenty of coaches would love the commitment to attend training that this team shared. Tribal law isn’t what it once was, but missing “ceremony”, which often meant a funeral with associated dance, is still very much an issue to the elders. “We were really impressed with the commitment of the boys to their training. Missing ceremony in the old days meant a spear through the leg! These days, the elders yell at them, but it’s punishment they were prepared to wear for the good of the team”, said Smith. Now think back to that “horror” trip you might have done to get to a Touch Football event, and spare a thought for the Ramingining boys, who at the start, had a pretty straight forward plan to take the bumpy road into Darwin for their first taste of Touch Football competition. “We got word about a week out that the road from Ramingining to Maningrida was impassable because of flooding, so it meant a change of plans – drive 40km, then a boat across a river – followed by a further 60km by road into Maningrida”, said Adams. “Joseph got his boat sorted – a small tinnie with a 30 horsepower motor on the back. We loaded up all the boys & luggage, and had to move fast with a tropical storm coming in. We hit a mud flat and had to lift the engine with everyone out to drag the boat to deeper water. Getting wet wasn’t the problem – but we all know there are plenty of big crocs in the river!” The team eventually got across the river…and without anyone getting taken by one of the local crocodiles. But with no car meeting them on the other side, and Smith having little luck using the local language to get help, it was looking like they might not get to their flight. Help eventually arrived, and for most of the boys, it was a nervous first flying experience. They didn’t know much about taking to the air, but knew a plane had crashed in the Territory only a few weeks earlier. The Ramingining Men’s Open enjoyed fine dining at 30,000 feet – snacking on sandwiches and dipping biscuits in orange juice!! And they touched down in Darwin at 6:10m….plenty of time for their first match at 6:50pm. Heading into that first game, only Cam Adams had been on a touch field before. By the end of the weekend, the Ramingining boys had had a great time – the highlight a seven-all draw with Alice Springs. “The boys thought that was the grand final….in fact I think they still think they’ve won”, said Adams. Cam Adams was not only impressed with the commitment of the team to the game, but also how quickly the community had come to accept him since his move from Western Australia last year. “It usually takes a long time to get the trust of the community. The fact as a new teacher I was trusted to get the boys onto this trip meant a lot to me”, said Adams. Kings of the NT Titles…Kings of Ramingining….at least for one weekend! And they’re already planning to do it all again next year….with the help of a bigger boat.Story taken from the Northern Territory Website.
