PHOENIX — With each bullpen session he throws, injured starter Johnny Cueto is moving closer to rejoining the San Francisco Giants pitching staff.With each day Cueto spends at the Giants’ minor league complex in Scottsdale, the veteran pitcher is helping to change an important part of the organization’s culture.Cueto, 33, left the Scottsdale complex Saturday to throw a 40-pitch bullpen in front of Giants coaches …
Science Daily asked, “Could salt crusts be key ingredient in cooking up prebiotic molecules?” What if the answer is “No”? Just asking the question must be newsworthy. It invokes the power of suggestion. Stefan Fox told members of the European Planetary Science Congress last week that his team cooked up a new idea about the origin of life. First, they imagined what the ocean chemistry might have been like 3.8 billion years ago. Then they added salt to their imagined seawater recipe. After performing experiments “evaporating solutions of artificial primordial seawater and then baking the salty residue in an atmosphere of nitrogen and carbon dioxide to volcanic temperatures of 350 degrees Celsius,” they found pyrrholes – molecules that can be found in heme and chlorophyll. The salt crusts bind to amino acids and stabilize them against evaporation, they said. So what? These molecules are not alive in any sense of the word. “Our aim is to identify types of small molecules that might have participated in a hypothetical next step of chemical evolution,” they said. So far they got some simple amino acids, peptides and pyrrholes. (Presumably the amino acids came from Miller-style lightning discharges or from comets, and were in very small concentrations – but Fox said there were hundreds of thousands of years in which they could have accumulated.) The astrobiologists at the conference were probably happy to hear about a new way to keep amino acids from being rapidly destroyed. “A clear chemical pathway for the development of the raw materials of life would add support to the theory of life evolving beyond Earth,” the article ended.Allowing storytellers into the science lab (12/22/2003 commentary) was a crime against humanity. It permitted all kinds of mischief to be tolerated in the name of science. Fox (who should stop following in the footsteps of the previous Fox, Sidney Fox, in mythmaking, but should watch Fox News instead), is apparently unaware that salt is the last thing you want around to cook up life (06/25/2009). But in the new Darwin Storytelling Contest view of science, anything that lends itself to bottom-up thinking (hydrogen to people) is considered progress. No matter the illogic and contradictions, these liars will take their amino acids with toxic salt if they have to. They need those building blocks of lie (03/19/2008).(Visited 5 times, 1 visits today)FacebookTwitterPinterestSave分享0
30 April 2014The sixth edition of the Bridge Cape Pioneer Trek international mountain bike stage race is set to be the best yet in the history of the event, which has been accorded UCI status by world cycling’s governing body.The event’s elevated status means it will attract more big-name professionals when it takes place from 12 to 18 October. As a UCI-graded race, standards relating to the racing end of the field, including the amount of prize money amount and depth, as well the awarding of UCI rankings points to top finishers, is assured.DistanceCovering 550 kilometres in seven days and taking in three different eco-regions of South Africa’s Western Cape province – the Great Karoo, the Klein Karoo and the Garden Route – the event includes the richest single stage in all of mountain bike racing.Although the route for the 2014 edition of the race is set to be announced by the end of next month only, it will still include the event’s trademark mountaintop finish of stage two, the Queen Stage, which will see the riders ascend the formidable, majestic Swartberg Pass.Equal prize moneyThis will be the first year that the first women’s team to the summit finish will receive the same prize money as the men.Bridge, the event’s title sponsor, has committed a total of R250 000 (about $25 000) to the stage, with the first men’s and women’s teams each receiving R125 000 (about $12 500).‘Absolutely delighted’“I’m absolutely delighted about the news of the equal prize money on the big mountain-top finish stage,” said Swiss marathon champion, Ariane Kleinhans, who, with RECM teammate Anika Langvad, won the event’s Queen Stage and the women’s race overall in 2013, said in a statement.“It is a demonstration of the organisers’ respect towards us ladies’ performances and their motivation to increase female participation in our great sport. Equal prize money will attract more top riders to the race and push us to a higher level. Us ladies will definitely do our best to make it an exciting race,” she added.‘Even more rider-focusedCarel Herholdt of Dryland Event Management, the company that founded and manages the event, commented: “Each year we fine-tune the Bridge Cape Pioneer Trek to be even more rider-focused,” said Carel Herholdt of Dryland Event Management, the company that founded and manages the event.“At the Bridge Cape Pioneer Trek, our focus is on quality, not quantity. Our stages aren’t long just for the sake it. They’re designed to offer as much reward as they offer challenges. They’re real mountain-biking routes that include some of the Karoo and Klein Karoo’s greatest natural spectacles.”SAinfo reporter
Share Facebook Twitter Google + LinkedIn Pinterest Many farmers who have experienced large grain harvests in recent seasons now realize they need more grain storage capacity as they look ahead to anticipated production for 2017.Installing a completely new grain storage system is a good long-term solution for expanding capacity and improving efficiency. However, for farmers who may be facing budget or time constraints this season, another option is an interim expansion strategy to help meet 2017 grain storage needs, according to GSI (Grain Systems, Inc.).Gary Woodruff, GSI conditioning applications manager, said there are cost-effective strategies to add more capacity for this season in a way that also enables new grain handling/storage equipment to be incorporated into a future new system on adjacent land.“A short-term, interim expansion this year can meet anticipated grain storage needs for 2017 more quickly and at a significantly lower cost than planning and installing a completely new grain storage system, yet still provide the components of a future new system,” Woodruff said.With careful planning and strategic choices in grain handling equipment, Woodruff says a storage or drying expansion now may become part of a later, larger system next to today’s outdated installation.Noting there are products that lend themselves to this type of expansion, following are Woodruff’s recommendations to meet 2017 storage needs:More bin capacity — If the site allows, farmers can add one or more storage bins next to their existing storage operation and later those new bins and a new driveway on the other side can be the start to a new, more efficient storage system. The extra storage will also allow the capture of extra income from the basis and carry by holding grain until spring or late summer. Generally, a single larger bin has a lower cost per bushel than multiple smaller bins. However, smaller bins might be required if different crops need to be stored separately.Grain handling — A new conveyor system may be needed to move grain into the new bin or bins. Conventional augers have the lowest cost, but are low capacity and higher in maintenance. Chain drag conveyor systems are a great option, but they are the most expensive. In comparison, a much lower-cost, more versatile alternative is a tube chain conveyor, such as GSI’s VersaLoop, which can span large distances without a support structure, doesn’t require a catwalk, offers high grain-moving capacity and efficiency and is easily expanded later. In some cases, a pneumatic air system can be used to move grain past the reach of the existing grain leg and be moved and utilized in the future system.New dryer — A stackable portable dryer may be a good option because it can increase drying capacity today and be expanded by 30% to 85% or more in the future with additional modules.Woodruff notes that the cost of an interim expansion project will vary by farm, depending on current and future capacity needs.“However, this two-step approach provides a much lower upfront cost, and is an investment that will support a future new system,” he said.For more information, farmers can contact their GSI dealer or visit www.grainsystems.com.
This theater trailer by the LA Times is a retro throwback showcasing the cutting edge video production technology of 1993!Oh you won’t want to miss this one – cheesy 90’s music, leather jackets with turtlenecks and Van Damme with a mullet!This video produced for the LA Times highlights what was leading technology of the early 90’s. LA cinematographer Paul Raimondi, who shot the video, recently pulled it ‘outta the vault’ and shared on Vimeo.It’s pretty amazing to see how far camera tech has come over the last 20 years. This equipment required hands-on control, whereas now many of these shots are created with wireless or computer controlled devices. Even the Steadicam featured in the video looks like a relic compared to the more advanced motion stabilization systems we have today.Really makes you wonder where we’ll be in the next 20 years! Thanks to Paul Raimondi, for sharing this one with the ‘net.
