With two outs on the scoreboard and the bases loaded Brian Orr hit a walk-off 2RBI single in the bottom of the ninth inning to cement a mammoth comeback and the Humboldt B52s stunned the visiting Fresno A’s 11-10, Saturday night at Bomber Field.Orr’s walk-off was the culminating act of a game-long comeback by the B52s, who fell behind 8-0 after the top of the first inning after a less-than-ideal season-opening performance from starting pitcher Craig Broadman, who gave up six earned runs in his …
f=”crev03.htm#amazing11″>03/27/2001), we reported on the discovery of prestin, a motor protein that acts as an amplifier in the inner ear. One of the fastest-acting molecular motors known (02/21/2002), prestin works by stiffening the rod-shaped cell body with its cilia. Somehow, the action of this motor protein amplifies hearing in mammalian ears by several orders of magnitude (09/19/2002). In the intervening years, cell biologists and physiologists studying prestin have debated its role in amplification. Some have thought that the cilia were the main players in amplifying the sound, as in non-mammals. Now, according to an article in Science Daily, prestin’s role is to affect the sensitivity of the entire cell, not just the cilia. Researchers at St. Jude Children’s Research Hospital bred mice with mutated prestin that extends the cilia instead of pulling them in. If cilia were the key agents of amplification, they should have shown more gain – but they did not. Somehow, prestin assists the entire cell to “bounce” more effectively in response to the sound ripples in the cochlear fluid. This whole-cell response is called somatic motility. “The researchers concluded that somatic motility was not simply a way to make cilia do their job better; rather, there is no connection between the hair cell contractions and how the cilia do their job,” the article explained. “Instead, somatic motility, generated by prestin, is the key to the superior hearing of mammals.” The presence of these prestin-assisted outer hair cells in mammals increases sound sensitivity a hundredfold, the article said. “The finding could explain why dogs, cats, humans and other mammals have such sensitive hearing and the ability to discriminate among frequencies.”Motors in your ears that amplify sound. What more could be said? He who has ears to hear, let him hear.(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0
As part of the programme, old coaches are also being refurbished, as well as revamping and modernising stations and signalling. A request for proposals was put out by Prasa in April for local companies to outline the design of a new train. Montana believed the country had to use this investment to revitalise its local industry, and a condition in the request for proposals stated that 65% of components must be manufactured in South Africa.‘Revitalising local industry’ Montana said he expected that this would create about 75 000 jobs, as well as boost the number of artisan skills in the country. A black economic empowerment (BEE) programme for the building of the new coaches would be announced shortly and Montana assured the committee that there would be a “huge stake for black businesses” – up to 40%. “Workers, disabled people and women must also be involved,” he said. Prasa is also refurbishing hundreds of coaches a year and about 15% of all train sets had been refurbished so far, he said, at a cost of about R7-million per coach. This financial year will see the overhauling of 530 coaches, at a cost of R2-billion, up from 200 coaches a year a few years ago. Added to this, Prasa would invest R7-billion into a modern signalling system and Siemens had already been appointed to carry out some of the work. In the long-term, onboard train protection – an electronic system which takes over from the driver should the driver not take action or should he have a heart attack – would also be installed.Safer, cleaner stations Montana said Prasa would also carry out 98 station improvement projects this financial year to improve safety and cleanliness. At some stations community members have been trained and have been assisted to set up co-operatives to clean stations. Modern speed gates, to the value of R1.9-billion, would also be set up at various stations across the country ahead of the introduction of a single transport card for bus and train commuters. According to Montana, Prasa would extend rail lines and a number of projects would be developed, including a Johannesburg-Durban High Speed Rail link – to reduce travel time between the two cities to three hours. Other projects include the Moloto Rail Corridor and the Johannesburg-Queenstown- Mthatha Rail project, of which R450-million had been committed over the next three years, which included the construction of eight stations. Rail links to Cape Town International Airport and King Shaka International Airport had also been proposed. South Africa, he said, could no longer afford to fall behind the rest of the world, having already missed several “rail revolutions” – including the introduction of modern commuter trains and high-speed trains in other countries. Source: BuaNews 20 June 2012 Plans to give South Africa’s passenger rail services a complete overhaul are on track as a preferred bidder for the building of 7 224 new trains will be announced in November, Passenger Rail Agency of South Africa (Prasa) chief executive Lucky Montana says. Briefing the National Council of Provinces’ (NCOP) select committee on public services in Cape Town on Tuesday, Montana said that the first of the new trains manufactured as part of Prasa’s 20-year fleet renewal programme are expected to be running in 2014.
The Nelson Mandela Bridge, named after South Africa’s first democratic President, has won several awards. The bridge is situated in Johannesburg.The Nelson Mandela Bridge get a pink illumination every year since 2012 to raise awareness for breast cancer. (Image: South African Tourism)Brand South Africa reporterParis has its Eiffel Tower, New York its Statue of Liberty, Sydney its Harbour Bridge. And downtown Johannesburg has the iconic Nelson Mandela Bridge.Named after the man who led South Africa across the apartheid divide, the bridge was opened by Nelson Mandela in July 2003. Crossing no less than 46 operational railway lines, the 284-metre-long bridge is largest cable-stayed bridge in southern Africa.Designed by Dissing+Weitling Architecture, the bridge has won numerous awards, including the South African Institute of Civil Engineering Award for Most Outstanding Civil Engineering Project Achievement in Technical Excellence category.The bridge links the Braamfontein business area with the Newtown precinct. Taking two years to build, the bridge was at the heart of a inner city renewal project by Gauteng province’s economic development initiative, Blue IQ. (Blue IQ has since merged with the Gauteng Development Agency to become the Gauteng Growth and Development Agency).The rejuvenation project aimed to create a “cultural arc” – a crescent from Constitution Hill through Braamfontein and down to Newtown, which is now known as the city’s cultural precinct.The bridge links important civic and cultural institutions: the Constitutional Court, the Civic Theatre and Wits University in Braamfontein; Mary Fitzgerald Square, the Market Theatre and the 1913 Museum Africa in Newtown.Other attractions in the area are the Dance Factory, the Sci-Bono Discovery Centre and the SAB World of Beer. The square regularly hosts several big events, including the Joy of Jazz festival and Diwali.During 2011’s Joburg Fashion Week, South African designer David Tlale turned the bridge into the longest ramp in the history of South African fashion. Tlale’s Made In The City collection featured 92 models in celebration of 92 years of Nelson Mandela’s life.Watch:In 2012, the City of Johannesburg and a cosmetics company lit the bridge pink for a week in an effort raise awareness about breast cancer.Facts about the bridgeNelson Mandela Bridge carries two lanes of traffic and has two sidewalks for pedestrians as well as a cycle path, with a continuous toughened glass parapet to ensure pedestrian safety.According to Construction Weekly:The asymmetrical dual-pylon cable-stay bridge is made up of a 66-metre north back span, a 176-metre main span and a 42-metre south back span, giving a total length of 284 metres.The north pylon is 42-metres high and the south pylon 27-metres high, creating a delicate balance and an interesting visual appeal.The main span was built as light as possible, using structural steel with a concrete composite deck, while the heavier back spans were built from reinforced concrete to counterbalance the long main span.The bridge is supported on the largest pot bearings ever to be installed in South Africa. The 1.5-metre diameter bearings, which have a capacity of up to 27 Mn, are designed to accommodate the large temperature movements of the bridge.Approximately 4 000 cubic metres of concrete and 1 000 tons of structural steel were used to construct the bridge, with around 500 tons of reinforcing steel cast into the concrete.Sources: South African Tourism, Dissing+Weitling Architecture, Gauteng Growth and Development Agency, Construction Weekly, and the City of Johannesburg.Would you like to use this article in your publication or on your website?

By: Bari Sobelson, LMFTPixabay[Baby Father Hug by Froot, November 21, 2017, CC0]When people think of child abuse and neglect, they often picture a physically and/or psychologically injured child. What they may not immediately picture is that same child as an adult with risky health behaviors, chronic health conditions, low life potential, and early death. What do these have in common? As the number of Adverse Childhood Experiences increases, so does the risk for the potential adult outcomes.On August 17 at 11 am Eastern, Dr. Melissa Merrick from the Centers for Disease Control and Prevention will be providing a 90-minute webinar on the ACE Study and what it teaches us about maximizing health and well-being. Not only are we offering beneficial and important information, we will also be offering 1.5 CEUs for those licensed mental health professionals (Social Workers, Professional Counselors, and Family Therapists) seeking credits.If you are interested in learning more about the ACE Study, you can find information and resources at www.cdc.gov/violenceprevention/acestudy/index.html.We look forward to seeing you at the webinar!
