Evolutionists in Utah are claiming to have run the evolutionary tape in reverse, says the BBC News: “US researchers have taken a mouse back in time some 500 million years by reversing the process of evolution.” How can this be? By engineering its genetic blueprint, they have rebuilt a gene that was present in primitive animals. The ancient gene later mutated and split, giving rise to a pair of genes that play a key role in brain development in modern mammals.But isn’t engineering a form of intelligent design? Not if the engineer is Mother Nature, according to Petr Tvrdik, who wins Stupid Evolution Quote of the Week for this concoction of personification and mixed metaphors: “It illuminates the mechanisms and processes that evolution uses, and tells us more about how Mother Nature engineers life.”No commentary necessary. The baloney smell tells all. A question, though: do the BBC science editors lack noses? Without a sneeze, they held up another fetid chunk from a co-researcher at the end of their report and in a prominent callout box: “It gives a real example of how evolution works because we can reverse it.” Phew.(Visited 8 times, 1 visits today)FacebookTwitterPinterestSave分享0
4 August 2011 China plans to set up a cultural centre in South Africa to promote artistic and cultural exchanges between the two countries, visiting Chinese Vice Minister of Culture Zhao Shaohua said this week. Shaohua made the announcement shortly before signing a programme of cooperation with acting Arts and Culture Minister Tokyo Sexwale in Pretoria on Tuesday. “The cultural relations between South Africa and China are flourishing,” Shaohua said. “Culture knows no boundaries, and I was impressed by the dance of South African cultural groups during our Shanghai World Expo last year. “To further cement our cultural relations, we will be establishing the Chinese Cultural Centre in South Africa very soon make the public aware of Chinese culture, as well as making greater contributions to China-South Africa cultural relations. “We both have a very long history and we believe that through this Cultural Centre, we exchange our cultural diversity.” Shaohua, who was speaking via a translator, also pledged 300 000 Chinese Yuan to develop cultural activities in South Africa.Artistic, cultural exchanges Sexwale said the agreement also looked at the possibilities of translation of Chinese books into South African languages and South African works into Chinese. “This agreement will go a long way in extended our cultural relations in arts, film, books, language and culture as well as exhibition of our cultural dancers together,” Sexwale said. “Through my observation, I’ve learnt that most foreign countries, including Germany and France, have language institutes in South Africa, so I want to propose that you set up your Chinese language institute as well.” The Human Settlements Minister, noting that China was the second-biggest economic powerhouse in the world, said that through the agreement, the two countries would encourage their artists to visit each other.Trade reaches new highs Bilateral relations between South Africa and the People’s Republic of China reached a new high point in 2009/10. By the end of 2009, the Department of Trade and Industry announced that China had become South Africa’s largest trading partner, with total trade amounting to approximately R120-billion. During the state visit by President Jacob Zuma to China last year, companies and organisations from China and South Africa signed over a dozen cooperative documents at a business forum, involving projects in areas such as solar power, mining, telecommunications, insurance and finance. A €240-million (about US$300-million) loan agreement between South African mobile phone operator Cell C and China Development Bank was included in the deals. The announcements also included the acquisition by South Africa’s Discovery Health of a stake in Ping An Health Insurance, a subsidiary of China’s second-largest Insurer, the Ping An Insurance Group. December 2007 marked 10 years since the official establishment of diplomatic relations between South Africa and China. Source: BuaNews

Professor Straube mentioned that he’s been talking with HVAC equipment manufacturers about this for about a decade, and they just don’t get it. Carrier and Trane, he said, have told him they don’t sell low capacity equipment because no one’s buying it. They failed to see that if the equipment is not available, no one can buy it so of course they’re not buying it because it’s not available. Evidently those discussions haven’t turned the corner yet.Specifying low-capacity equipment won’t save you any moneyStraube covered a lot of ground in his presentation. After introducing the need for low-capacity mechanical systems and the lack of conventional equipment, he dove into the details of the different systems available, how they work, what some of the limitations are, and how difficult it is to do it right.One of the big obstacles is cost. “We’re beyond talking about saving money on equipment for low-load houses,” he said, because you won’t. If you’re a spray foam contractor, for example, trying to get builders to bite on the higher cost of foam because of savings they’ll see from smaller mechanical systems, it’s not gonna happen.You can get a 46 kBTU/hr 95 AFUE furnace for $697. If you want something with less capacity, you could go for a boiler, tankless water heater, or minisplit heat pump, all of which are significantly higher in cost.The same is true of air conditioners. When you go from a 2-ton system to a 1.5-ton system, it costs more and is less efficient, too. So if you want a low-load building to have a low-capacity mechanical system, get used to higher cost.Returning water temperature affects efficiencyIn the first half of the day, Straube went through some of the basics of efficiency ratings (SEER, EER, and COP), details about condensing boilers and furnaces, and combo systems (using one system to provide heat and domestic hot water). He talked about some of the problems with condensing systems and the temperature of the entering water or air.If you think you have a boiler that’s 95% efficient, for example, you may not be getting that if the water returning in the hydronic distribution system comes back too warm. Condensing boilers and furnaces work by extracting the latent heat from the water vapor in the exhaust gases. They’re able to do so as long as the heat exchanger is below the dew point. If the returning water (or air in an air distribution system) is above the dew point, the water vapor doesn’t condense, the boiler/furnace doesn’t extract as much heat, and the efficiency goes down. The graph of condensation efficiency shows how the efficiency changes with returning water temperature.Desuperheaters? Thumbs downAfter lunch, the discussion turned to heat pumps, both conventional, ground source, and minisplits. He blasted the idea of using desuperheaters on ground-source heat pumps to get hot water because they’re usually not cost-effective and don’t give you much hot water. Ground-source heat pumps work well in school-sized buildings, he said, but not so well for low-load buildings or really big buildings. He also said that he has not seen any third party data on GSHP efficiency showing a COP higher than about 3. Since the industry doesn’t include pump or blower energy in their COP calculations, Straube said, their COP numbers are higher but don’t give the complete picture.The topic was mechanical systems, so there was also talk about water heating. Combo systems give you both heat and hot water, and some people use water heaters just for space heating, too. Straube mentioned that HVAC and DHW need to come together.Looking back over my notes now, I still can’t believe how much material he covered. It really was a tsunami of information. He also spoke briefly about using CO2 as a refrigerant in air-to-water heat pumps, which allows true hot water production because they can get higher temperatures than the standard refrigerants; electric resistance heat, which is OK in some cases for low-load buildings; Legionnaire’s disease, which can be a problem if the DHW temperature is too low; heat pump water heaters; distribution of thermal energy (air, water, radiant); and more.The wit of Professor StraubeAs I mentioned at the beginning, Professor Straube is not only incredibly knowledgeable, he’s also a walking quote machine. Here are a few of the many witticisms we were treated to yesterday:Caveat emptor is Latin for “you’re gonna get screwed.”Cats are IAQ problems and you’d have to pass them through the HRV to solve that problem. But they’re not really a cat anymore after that.Recirculating range hoods don’t solve the IAQ problem. It’s like a recirculating toilet. The stuff just goes round and round and never leaves.In San Francisco, it never gets really hot or really cold. Buildings are there mainly to keep people away from your stuff.It’s taken America 10 years to realize that tankless water heaters work better with tanks.If you ever get a chance to go to one of his talks, I guarantee you won’t have any trouble staying awake and engaged.A great reason to be a GBA Pro!Not everyone can take the time to go off to New England for two days to attend a session like this. The good news is that many people watched the whole thing from their home or office because Green Building Advisor ran a livecast of the sessions.Anyone could have signed up through Building Science Corporation for the regular fee of $395 per day. GBA Pro members, however, got access to the livecast as part of their membership. What a deal! GBA Pro members will also get to watch some of the recorded videos from the Building Science Experts’ Session once they’re posted.

His topic, a good one for GBA readers, was mechanical systems for low-load buildings.You know that expression about how the information comes at you so fast in some classes that it’s like drinking from a firehose? With Professor Straube, it’s like trying to drink from a tsunami! The guy has not only a phenomenal knowledge but he’s also a fantastic teacher and incredibly witty.Giving you a good overview of everything Straube talked about would be quite a challenge (and result in an article longer than anything Martin Holladay has written here!), because he really covered the whole gamut of this topic. So, I’ll throw out a few highlights of the day here and encourage you to attend one of his workshops if you ever get the chance.You may also get the opportunity some day to buy his book on this topic. As we were talking on the last night, Joe Lstiburek and others strongly encouraged Straube to get this knowledge into a book, and I hope he does.It’s hard to find a furnace rated at less than 40,000 Btu/hBuilding enclosures have improved dramatically in the past two decades. We have more insulation, better windows, and sealed air barriers. Many homes have peak heating loads of 15 to 30 thousand BTU per hour (kBTU/hr) — even in cold climates. This applies to large houses and buildings, too, because high performance enclosures result in zones with low loads. The problem is that most conventional heating equipment available doesn’t go that low in capacity. About the smallest furnace you can get is 40 kBTU/hr.
PARIS – Defending the French language does not mean refusing to speak other languages, French President Emmanuel Macron said Monday, alongside Quebec Premier Philippe Couillard.The two leaders met for the first time since Macron’s election in May 2017, at the Elysee Palace, the president’s official residence in Paris.Macron, who has been criticized in the past for speaking English in public, was asked by a reporter whether he was doing enough to defend the status of the French language around the world.The president said he was inspired by what he called the “North American example.”“I never hesitate to express myself at times in French or in the language of the host country or equally in English while on the international scene or in front of business groups because I think that reinforces the francophonie,” he said.Macron added he wants to show that French is not an isolated language, but an integral part of multilingualism.Couillard said most Quebecers agreed with Macron’s statement. They want to defend French, he said, but Quebecers also want to learn other languages.The premier announced Macron would address the provincial legislature in Quebec City in June when the French leader in the province for the G7 meeting.Couillard also discussed the controversy surrounding the office of Michaelle Jean, the former Governor General of Canada who is head of the Organisation internationale de la Francophonie, the body that represents the world’s French-speaking countries.Jean has lead the organization since 2015.The Quebecor media company reported last year Jean spent $500,000 in public funds to renovate the official residence she rents in Paris, and that she spent $20,000 to buy a piano.Couillard said he was proud to see a Quebecer at the head of the francophone organization and that he wanted her mandate to be successful, but he called for better accounting and transparency in the use of public money.The premier visited Jean at her office Monday and met with personnel.Journalists covering Couillard’s trip asked for a meeting with Jean, but a spokesperson said she was busy.One of the main themes of Couillard’s trip is aerospace and on Tuesday, Couillard is scheduled to tour the Airbus factory in Toulouse and meet with management.Last October, the European aircraft manufacturer acquired a majority stake in the C Series, the flagship aircraft of Bombardier.
