Carol of the Birds

first_imgCan birds make you happy?  Some scientists think so, but why?There seems to be a connection between seeing birds in their natural habitat and a person’s sense of well-being, reported Science Daily. Whether that is true may be a function of the setting and species of bird (buzzards, ostriches probably not rating as high as cardinals in the snow), but Natalie Clark of the University of Reading is convinced:Most of us say we enjoy seeing wild birds in our local environments every day, be that the friendly robin visiting our garden each Christmas or ducks swimming in the local pond. But we have little idea of how much we value their presence and how they’re contributing to our overall well-being.The idea is reinforced by the number of people who place bird baths or hummingbird feeders in their gardens, beyond the avid bird watchers themselves.  Without the sweet songs of birds, their visible beauty and their amazing powers of flight, the world would be an impoverished place.There have been several Christmas songs titled “Carol of the Birds.”  The oldest and best known is probably this traditional Catalonian carol whose lyrics are reproduced at HymnsAndCarolsOfChristmas.com.  Its hauntingly beautiful melody can be heard on YouTube sung by Victoria de Los Angeles, accompanied by cellist Luis Claret, as performed at the closing ceremony of the 1992 Barcelona Olympics.A little bird tweeted a tip that Illustra Media is working on a full-length documentary on birds, to be released in Spring 2013.  If it’s anything like their latest film Metamorphosis about butterflies, you know it will be a keeper.

When Do I Need to Perform a Load Calculation?

first_imgIn my last three blogs, I discussed the basics of heat-loss and cooling load calculations. The unfortunate truth about these calculations is that fast methods aren’t particularly accurate, and accurate methods require making measurements, checking specifications, and entering data into a computer program — in other words, a significant investment of time.So how should builders go about making these calculations? There are several ways:There are at least two reasons why we need to perform load calculations: to size heating and cooling equipment (ideally, using ACCA Manual S), and to design heating and cooling distribution systems (using ACCA Manual D). Neither Manual S nor Manual D can be used unless Manual J calculations are performed first.These are valid reasons, so a room-by-room Manual J load calculation makes a lot of sense. If you perform such a calculation, you may save money on your heating and cooling equipment (because it is less likely to be oversized), and there will be a lower chance that the homeowners will have comfort complaints arising from a poorly designed heat-distribution system.In most areas of the country, a room-by-room Manual J load calculation is required by code. If you don’t have the software yourself, you’ll have to hire an energy rater or engineer to perform the calculations. Very few HVAC contractors are capable of performing an accurate load assessment, so I’d be wary of leaving this task to your furnace guy.As long as there is no code requirement in your jurisdiction for a Manual J calculation for the type of work you are contemplating, you may not need a Manual J calculation. To understand why, we need to examine two myths that have long been promulgated by energy experts. The first myth is that rules of thumb are inappropriate;… Start Free Trial Already a member?

Indian shuttlers happy after BWF defers mandatory skirt rule

first_imgIndian shuttlers and officials on Monday welcomed the Badminton World Federation’s decision to defer the controversial mandatory skirt rule till December and hoped that the body would come up with a better regulation after fresh deliberations.Shuttler Jwala Gutta has welcomed BWF’s decision to suspend the mandatory skirt rule. AgenciesThe BWF Council in its meeting in Qingdao, China decided not to introduce the regulations regarding the mandatory use of skirts and to “further investigate the new clothing regulations after accepting a recommendation from the Women in Badminton Committee.”The mandatory ruling was initially supposed to be implemented on May 1 but after feedback from various quarters, was deferred by one a month to June 1.The rule had been fiercely opposed by India and some other Asian nations.India’s top doubles player Jwala Gutta said the BWF has done the right thing by going back to the drawing board to look for a more viable regulation.”It is a very good decision by the BWF. They couldn’t have gone ahead with the mandatory skirt ruling anyways. It can never be a compulsion on the players and it is good that they are rethinking about the decision,” Jwala said.Badminton Association of India Vice President TPS Puri also welcomed the decision of the governing body.”This is the right approach by the BWF. If it would have been made compulsory then many players would have become uncomfortable. A lot of nations, including India objected to the mandatory nature of the ruling and we welcome this decision of the governing body,” Puri said.advertisementThe decision to defer the implementation of the ruling was made after receiving feedback from the Athletes Commission, which represents the players’ interests in the BWF Council with full voting rights.”There have been various feedbacks from many quarters and after taking into account all these comments, especially those from the Athletes’ Commission, it is our recommendation to Council to do further study before implementing new clothing regulations,” former world champion Nora Perry, who heads the Women In Badminton Committee, said.”It is still our intention to focus on a better presentation of the game, but we would like to broaden the scope to include both men and women, and the feedback will also include views from various stakeholders such as the clothing manufacturers,” said Perry.”The Committee is also pleased that the BWF Council has accepted our recommendation and we would continue to work closely with the Athletes Commission, clothing manufacturers and other stakeholders to prepare a new proposal with a broader scope to Council in December,” she added. .Jwala said it is good that the committee has decided to bring apparel manufacturers on board.”It is nice that they are working closely with the cloth manufacturers. Hopefully they can come out with designer on-court outfits which will help raise the glamour quotient and the profile of women in badminton,” she said.Former shuttler Madhumita Bisht, who became the national sub-junior champion in 1977 and went on to become an eight-time national singles champion and nine-time doubles winner, said the number of times the ruling has been deferred indicates that the BWF is taking time to come out with the right regulation.”First they made it May 1, then June 1 and now December, it only shows they are on the right track and taking enough time to come out with the right decision,” she said.”Countries such as India, China, Indonesia and some European countries also objected to it and they can’t make it mandatory. Now I hope they will go through it properly and talk with all the associations and come out with a right approach.”It should always be the players’ prerogative to decide what they would wear and what makes them comfortable. If the ruling is restrictive in nature, it will hamper their performance. The BWF will definitely look into it now,” she added.- With PTI inputslast_img read more
