Four houses sank into the 20-foot-deep fissure, while tons of dirt carrying fully grown pines and eucalyptus shoved a wall of road asphalt and broken curb into two houses on the next street below. Seven houses were so severely damaged residents can’t even get inside, and 22 more are off-limits except with safety escorts. Residents who live near the slide zone criticized the city for not warning that a slide was possible after concerns about water main leaks, sinking curbside meters and creeping gaps in the sidewalk first cropped up in July. “We are helpless,” said Joseph Tsai, a retired engineer who moved to Mount Soledad 12 years ago. “It depends on the city to address the problems.” City officials have said they were considering new vehicle weight limits and other stopgap measures early in the week but didn’t realize a collapse was imminent until shortly before it happened around 9 a.m. on Wednesday. Residents of the four houses directly atop the collapse were advised late Tuesday not to sleep in their houses, but they weren’t forcibly evacuated that night; homeowners whose properties were buried said they had no warning that the mountain was crumbling. “There was no indication they were at risk,” said Bill Harris, a city spokesman. Harris said the city is conducting a comprehensive investigation of the events leading up to the collapse. But he said no decision has been made about how to make sure the hillside remains in place, and the city currently has no plan to broaden testing beyond the immediate slip zone to determine whether other parts of the neighborhood are threatened. Experts said the likelihood of a second collapse on a similar scale is low, but smaller slides may be possible as the earth settles in its new, lower, resting place. Meanwhile, pavement has been cracking on streets in another nearby Mount Soledad neighborhoods, and residents have hired geologists in an attempt to determine whether a similar slide is imminent there. “I’m worried that this hill is going to collapse,” Cindy Goodman, who lives in a $2 million home in the area, told the San Diego Union-Tribune.160Want local news?Sign up for the Localist and stay informed Something went wrong.

SAN DIEGO – Jeanne Plante didn’t pay much attention this summer as city engineers worked to figure out why the busy road up the hill from her house was ominously cracking apart. When the ground below the road suddenly collapsed this week, taking four houses with it and burying two others, Plante was caught off guard. Now, she and her neighbors want to know why it took so long for the city to recognize a major landslide risk was imminent, and what officials plan to do to prevent similar failures in the neighborhood. “If it happened to them, what’s to stop it from happening to us?” she said shortly after she was allowed to return to the $1.7 million gray-stone property, which sits about 100 feet downslope from the toe of Wednesday’s landslide. “And if they don’t cover what happened up there, could we get hit twice?”
Hayes & Yeading United have re-signed defender Yassin Moutaouakil on the eve of their Southern League campaign.The French full-back first joined United in August 2011, when they were in the Conference Premier.He had been without a club for more than a year, following his release by Charlton Athletic, and went on to make 28 appearances for Hayes & Yeading.In January 2013, he left for Portsmouth and played 32 times for them in League One and Two.Now 30, Moutaouakil – who has also played for Motherwell – could play for United in their opening game at Frome Town on Saturday.See also:Defender leaves United to join PompeyStones sign former Watford wingerUnited youngster having trial with BladesWhere you can support Non-League Day this weekendFollow West London Sport on TwitterFind us on Facebook

Scientists continue to make headway understanding the detailed workings of molecular motors. The two most famous rotary motors yielded additional secrets recently:ATP Synthase: “Making ATP” was the short title of a paper in PNAS this week.1 Xing, Liao and Oster came up with a model that linked the rotation of the gamma subunit (the camshaft) to the beta subunits in the F1 hexamer, where ATP synthesis occurs. They identified two “bumps” in the potential curve that prevent back-slippage of the rotor. The shaft is tightly coupled to the lobes, to produce a kind of “zipping” effect of hydrogen bonds as the beta subunits bend along a hinge during the catalytic function. The eta part of the stator is apparently also essential in preventing slippage, in order to couple the energy to the synthesis function. Mutations were shown to flatten the “energy bumps” on the potential curve, making slippage more likely. They also noted that in ATP hydrolysis mode (the reverse cycle) ADP tends to get stuck in the mechanism; “this is hardly surprising,” they said, “because F1 evolved to synthesize, and only under laboratory conditions does the eukaryotic F1 operate in hydrolysis mode.” The bacterial ATPase and vacuolar ion pump do operate in hydrolysis mode in vivo and presumably do not have this inhibition problem. Their lingo on this point mixes design and evolution: “The V1 motor of the vacuolar ATPase, being designed for ion pumping, may have avoided ADP inhibition by the evolution of additional subunits” (emphasis added in both quotes).Bacterial Flagellum: A Japanese and UK team publishing in Nature2 found stepping behavior in the flagellar rotor by direct observation. The torque generation by the ion flux may be responsible for the rotation taking place in measurable steps. Their observations “indicate a small change in free energy per step, similar to that of a single ion transit.” They mentioned that this had been seen in ATP synthase, but never before in the bacterial flagellum. They measured about 26 discrete steps per revolution. There was no mention of evolution in the paper.Type III Secretion System (TTSS): The TTSS, a kind of molecular syringe embedded in the membrane of some bacteria that allows them to inject toxins in nearby hosts, was also described more fully in the same issue of Nature by two Yale scientists.3 They found that the protein ordnance is too large, so there are special chaperones on hand to unfold them before loading them into the barrel. 1Xing, Liao and Oster, “Making ATP,” Proceedings of the National Academy of Sciences USA, published online before print October 10, 2005, 10.1073/pnas.0507207102.2Sowa et al., “Direct observation of steps in rotation of the bacterial flagellar motor,” Nature 437, 916-919 (6 October 2005) | doi: 10.1038/nature04003.3Akeda and Galan, “Chaperone release and unfolding of substrates in type III secretion,” Nature 437, 911-915 (6 October 2005) | doi: 10.1038/nature03992. See also the News and Views section by Blaylock and Schneewind, “Microbiology: Loading the type III cannon,” Nature 437, 821 (6 October 2005) | doi: 10.1038/437821a.Some evolutionists have identified similarities between the TTSS and the bacterial flagellum, and suggested that the flagellum evolved from the TTSS by co-option. There are many problems with this suggestion, not the least of which is that most of the protein structural parts of the flagellum are unique. The authors of the TTSS paper did not mention this suggestion or anything about evolution. In fact, evolutionary theory was useless for all three papers. Describing the machines in terms of their design was perfectly appropriate, illustrating again the utility of scientific research from a design perspective. The two brief mentions of evolution in the ATP synthase paper were useless appendages, like vestigial organs of a less-evolved philosophy (sarcasm intended).(Visited 5 times, 1 visits today)FacebookTwitterPinterestSave分享0
5 May 2014The Independent Electoral Commission (IEC) has released three mobile phone applications (apps) ahead of Wednesday’s general election.Using the first set of apps, voters can get the election results in real time as they are captured, from the first result to the last, including the final seat calculation and allocation.“Voters will be able join us and all our stakeholders in the journey of monitoring the correctness of what is captured and calculate the final results with us,” IEC chief information officer Libisi Maphanga said on Friday.The apps also provide information on voter registration status, voting station locations, candidates lists, frequently asked questions, contacts and more. They can be downloaded free from all major app stores on Android, BlackBerry, Apple, Windows 8 and Symbian platforms.Links to the downloadsThe second app, the “IXSA” app, is a 3D digital game which introduces first-time voters to the voting process in a fun, interactive way. The game can be downloaded free from Android and Apple app stores and is also available to play on Facebook.The game allows users to pick an avatar and then follow this character on Election Day, facing a number of challenges along the way. Players earn points for how election-savvy they are and can complete against other South Africans by posting their scores on social media and challenging their friends to beat their score.The IEC’s deputy chief electoral officer for outreach, Nomsa Masuku, said the game was about making the voting process accessible to young people in a format they were familiar with.“Learning is best achieved when people are having fun and don’t feel like they are being taught,” Masuku said. “The digital gaming world is the perfect place to combine education and entertainment.”The third set of apps are APIs (application programming interfaces), designed to give the media, political parties and other interested stakeholders automated real-time access to election data using their own apps on any online platform of their choice.Source: SAnews.gov
Share Facebook Twitter Google + LinkedIn Pinterest By Doug Tenney, Leist MercantileHarvest progress continues to be disappointing for many across Ohio. For the most part it is not disappointment in the harvest to date but rather for what yet remains for corn and soybeans to be harvested across the state. The last half of October, like much of the growing season, provided bountiful rains for Ohio.The Nov. 8 USDA Monthly Supply and Demand Report lowered corn ending stocks and increased soybean ending stocks. Those changes were expected but the ways they got there were not similar. U.S. corn ending stocks for the 2018-19 marketing year were 1.736 billion bushels, down 77 million bushels from October. The biggest change for corn came with U.S. production at 14.626 billion bushels. The October production estimate put corn at 14.778 billion bushels. Traders and producers alike were expecting the corn yield to be reduced as it was estimated at 178.9 bushels per acre, down 1.8 bushels from the October estimate.Corn open interest (total number of outstanding contracts) early in November reached its highest level since August 23. The first two trading days of November saw corn open interest climb over 39,000 contracts. Some are suggesting this activity could indicate that commodity fund traders have been active buyers and they see a longer term “story” of higher prices yet to come. This activity comes just days ahead of the Nov. 8 report that revealed China’s corn stocks could be much higher than earlier expected. Corn prices on that report day did close down one cent, but did not fall out of bed on the higher stocks number.The market has feared for decades what the actual China corn stocks number could be. Traders are not expecting increases in corn exports out of China. USDA did not increase at all their projections of China corn exports in spite of higher production and ending stocks in comparison to October numbers. It is a well-known fact that China is investing heavily into corn ethanol production with dozens of plants expected to be up and running in the next two years. Weekly corn auctions in China have been taking place for months with little traded at times. In addition, their corn inventory is thought to be of poor quality as well as not logistically in position to be exported. Also, China’s corn consumption is expected to increase 5% in the next year as they expand the starch and sweetener industries.U.S. soybean ending stocks continue to be on the increase as USDA pegged ending stocks at 955 million bushels, a jump of 70 million bushels. This increase comes on the heels of USDA lowering U.S. soybean exports to 1.9 billion bushels, a decline of 160 million bushels in just one month. This export decline was not a surprise with the U.S./China trade issues, which have been plaguing U.S. producers since May. U.S. President Trump and China President Xi are expected to be meeting late this year at a G20 meeting in South America to talk trade and other issues. There are indications of China acknowledging that both the U.S. and China have been hurt from the ongoing trade issues.Basis levels for both corn and soybeans have seen improvement in recent weeks as harvest has been winding down. However, those basis gains are changing at different rates across the state. For example, mid-November, Cincinnati is seeing only a flat price gain of 4 cents on soybeans from November to December. Other parts of Ohio are seeing that flat price gain of 10 cents to just over 20 cents. Likewise corn in Cincinnati is seeing a 6-cent gain for that same time period. Other parts of Ohio we seeing a flat price gain of 20 to 30 cents for that same November to December period.It is no surprise that this was a very difficult harvest season across Ohio. Producers with storage and drying capabilities were rewarded with the ability to keep harvesting as the weather permitted. Those without home storage were most frustrated as numerous elevators for much of October limited soybean moisture to 14% to 15%. Cloudy days with daily highs below 50 degrees provided little drying of soybeans still standing in fields.
