Scaling of basal metabolic rate with body mass and temperature in mammals

first_img1. We present a statistical analysis of the scaling of resting (basal) metabolic rate, BMR, with body mass, Bm and body temperature, Tb, in mammals. 2. Whilst the majority of the variance in ln BMR is explained by ln Bm, the Tb term is statistically significant. The best fit model was quadratic, indicating that the scaling of ln BMR with ln Bm varies with body size; the value of any scaling exponent estimated for a sample of mammals will therefore depend on the size distribution of species in the study. This effect can account for much of the variation in scaling exponents reported in the literature for mammals. 3. In all models, inclusion of Tb reduced the strength of scaling with ln Bm. The model including Tb suggests that birds and mammals have a similar underlying thermal dependence of BMR, equivalent to a Q10 of 2·9 across the range of Tb values 32–42 °C. 4. There was significant heterogeneity in both the mass scaling exponent and mean BMR across mammalian orders, with a tendency for orders dominated by larger taxa to have steeper scaling exponents. This heterogeneity was particularly marked across orders with smaller mean Bm and the taxonomic composition of the sample will thus also affect the observed scaling exponent. After correcting for the effects of ln Bm and Tb, Soricomorpha, Didelphimorphia and Artiodactyla had the highest BMR of those orders represented by more than 10 species in the data set. 5. Inclusion of Tb in the model removed the effect of diet category evident from a model in ln Bm alone and widely reported in the literature; this was caused by a strong interaction between diet category and Tb in mammals. 6. Inclusion of mean ambient temperature, Ta, in the model indicated a significant inverse relationship between ln BMR and Ta, complicated by an interaction between Ta and Tb. All other things being equal, a polar mammal living at −10 °C has a body temperature ∼2·7 °C warmer and a BMR higher by ∼40% than a tropical mammal of similar size living at 25 °C.last_img read more

RBR Student Remembered with Vigil

first_imgBy John BurtonRED BANK – With the sudden death of an 18-year-old Red Bank Regional High School senior, the leader of a local community organization felt it was appropriate to honor the girl’s memory by way of a public vigil.Linda Clark, who founded the Count The Children Move­ment in the borough, organized the candlelight vigil for Sept. 14, in response to the death of Riyadhna Farrow.“We looked at it as something where we could come out and support the family and to let her friends share their love,” Clark said.According to Clark, the vigil brought about 200 people to Montgomery Terrace, where the student lived with her family.Capt. Darren McConnell, a Red Bank police spokesman, said Farrow’s death “appears to have been from natural causes,” but additional tests have been conducted. “I can tell you we ruled out any kind of foul play,” he said.“She deserved to be remembered for who she was,” said Clark, a lifelong resident.Among the roughly 200 who gathered at the Ever­green Public Housing development were fellow students, high school administration representatives, local clergy, Mayor Pasquale Menna and the six borough council members, according to Clark.Councilwoman Sharon Lee noted that similar events in the recent past have been set into motion by violent acts or to make a political statement, such as one held in the aftermath of the Trayvon Martin shooting in Florida.The gathering for Farrow wasn’t for a political reason and was attended by many fellow students. “It was grief,” she said. “It was sorrow over the loss of one of their peers.”Farrow, Lee said, was a good student, excelling in math and science, working part time at Foodtown, Broad Street.“She had focus and direction and a lot of young people don’t have that today,” Lee said. “She was a role model.”What also struck Lee was how the young people depended on each other for support. “They needed to come together and hug each other,” she said. “That’s one of the things I noticed, the prolonged hugs.“It was very comforting to the family to see so many young people come to her home and express their concern,” Lee said.The gathering provided a chance for an impromptu fundraising effort, to assist the family with funeral costs, collecting $1,150, Clark said.Farrow’s funeral service was held Tuesday evening, Sept. 18, at Pilgrim Baptist Church, 172 Shrewsbury Ave. She is survived by her parents, six brothers and four sisters.last_img read more

Sports, life hard to predict

first_img AD Quality Auto 360p 720p 1080p Top articles1/5READ MOREThe top 10 theme park moments of 2019 But it did Saturday evening to Thomas Herrion in the 49ers’ dressing room at Invesco Field at Mile High, as he suddenly collapsed and never regained consciousness. Such a death on a stage as high profile as the NFL results, inevitably, in widespread scrutiny, for not only its sheer implausibility but also for its discomforting reminder of the numbing fragility of life. When any human being expires prematurely, it always is accompanied by much hand-wringing, soul-searching, head-shaking and philosophical-rationalizing. On ESPN’s Sunday morning Sports Reporters, the participants brought up the training camp death of Minnesota’s 340-pound Korey Stringer a few years ago, and were critical of the trend in recent years in the NFL as well as college and even high school of so many monstrous, 300-pound linemen. The intimation was that Herrion’s weight contributed to his death, and that he might never have died had he only kept it below 300. But how, then, does one explain other deaths that happen in sports where athletes have normal physiques? Thomas Herrion’s passing is yet another frightening reminder that there are no guarantees for anyone in this world in which we all arrive involuntarily and seldom depart voluntarily. Why certain people with great promise and kind hearts depart young and others with no redeeming qualities whatsoever live into old age is one for theologians, medical scientists and philosophers to figure out, and far beyond my limited comprehension. In a more uplifting scenario Sunday, a former left handed pitcher for the Long Beach State 49ers, Jason Vargas, dispensed an extraordinary effort against the Los Angeles Dodgers, limiting them to six hits and striking out seven in nine innings for his fourth victory with the Marlins since being called up last month against a mere one loss. Who during the 2004 college baseball season ever would have envisioned Jason Vargas making a dramatic impact in the big leagues in 2005, while his more celebrated teammate, Jered Weaver, still would be stuck in the minor leagues? After all, Jered Weaver was the National Player of the Year for the 49ers, going 15-1 with a 1.62 ERA and 213 strikeouts in 164 innings. He was selected in the first round by the Angels, and there were those who thought he’d wind up pitching in Anaheim by late last season. Alas, he and his agent, the notorious Scott Boras, got into a serious contract dispute with the Angels, and Weaver didn’t sign with them until this past June hours before he would have gone back into the amateur draft. Meantime, Vargas, who had a far less appealing 7-6 record with the Dirtbags with a 4.14 ERA and, 90 strikeouts in 110 innings, was taken in the second round by the Marlins. “Troy Buckley (Dirtbags pitching coach) and I spoke to Jason Sunday night, and congratulated him on his tremendous performance against the Dodgers,’ related Mike Weathers, coach of the Dirtbags. Obviously, he’s pretty pumped up. I’m not amazed at all by what he’s done because we knew all along that one day he would be in the majors.’ But in 2005 and before Jered Weaver reached such a plateau? Who could have foreseen such a surprising development? But there was Jason Vargas, who also was a DH for the Dirtbags and led the team in batting with a .354 average with 33 RBI and five home runs, receiving hugs and handshakes from the likes of Dontrelle Willis and A.J. Burnett and Miguel Cabrera and Carlos Delgado and Josh Beckett after his terrific outing Sunday. And where was Jered Weaver? He was immersed in obscurity in Little Rock, where his Arkansas Travelers were hosting the Frisco Roughriders. Weaver has posted a 2-1 record with a 4.91 ERA with the Travelers after going 4-1 with a 3.82 ERA with the Cucamonga Quakes. In retrospect, Jered Weaver and Scott Boras made a terrible miscalculation in trying to squeeze the Angels for more money, which they failed to do, for it needlessly kept Weaver sidelined for more than 400 days. In the meantime, Jason Vargas signed quickly with the Marlins, honed his skills in the minor leagues last summer and now finds himself in the middle of an interesting National League wild card race with the Marlins. He also is receiving major league wages, and now has a year credit in his major league pension. Jason Vargas upstaging Jered Weaver? At least for the moment, he is. It always has been my most hallowed theory that one never knows what lurks around the corner for any of us, and the weekend destinies of Thomas Herrion and Jason Vargas are vivid proof. 160Want local news?Sign up for the Localist and stay informed Something went wrong.

It has been repeated so often that it’s become trite to say that athletics, with its maddening uncertainties, is a graphic reflection of life, although it happens to be true. Two weekend events in different sports that occurred far apart could serve as classic examples, with one, the Thomas Herrion death, having tragic overtones and the other, the Jason Vargas complete game pitching victory for the Florida Marlins, rivaling a storybook saga. center_img Death is not a condition one normally would associate with a 23-year-old, 310-pound football player who had performed in just one series of an exhibition game that his team, the San Francisco 49ers, had played against the Denver Broncos. Death for someone that age normally occurs from an automobile accident, or a drive-by shooting, or a drug overdose, or even from suicide, but it isn’t supposed to strike a hulking, healthy man trying to earn employment as a guard with the 49ers. last_img read more

Charmaine Mrwebi, dreaming and writing in Setswana

first_imgUnable to find books written in her mother tongue, telling stories that related to her life, Charmaine Mrwebi wrote her own – and set up a distribution platform for her own and other writers’ books.Charmaine Mrwebi uses her love of the performing arts to help kids in the Free State learn about their world. (Image: Charmaine Mrwebi)Sulaiman PhilipEveryone should read says Charmaine Mrwebi. The published author, librarian and founder of the Charmza Literary Club says: “Our people should visit our libraries and become friends of books. Remember, any person who reads books on a daily basis, develops listening skills. Reading helps learners and students to perform better at school.”Charmza Literary Club visits schools around Thaba ‘Nchu, her hometown, where she shares her love of reading and its importance through poetry readings and puppet shows. She wants to empower communities to be able to tell their stories in their own language. “We also teach adults the necessary writing steps on how to write their books, edit and publish them in their language.”Mrwebi uses her monthly school visits to identify young writers to mentor, to encourage them and let them know they are not working in isolation. Once they have been identified, Mrwebi will, “…donate books to these writers after they have formed their book clubs, poetry groups and reading clubs”.She says that these visits bring her the greatest joy, especially if she gets to tell stories in her mother tongue. “I love that the children can get to teach me new songs. Or tell me a story their grandmothers told them. The more books we read together or stories we tell the more they open up and feel safe sharing their experiences.”As an author and poet, she feels blessed to belong to a community that passes on lore, history and culture from one generation to the next. The world is blessed, she says, by having writers who share their love of words. “When each one teaches the other, eventually we are going to have a community of writers telling stories and contributing towards solutions in our country. I feel that I have to keep pushing and investing in the seed of literature continuously even in the midst of challenges.”Charmza Literary Club gives children the opportunity to tell stories in their mother tongue. (Image: Charmaine Mrwebi)Among her first published books was Mantlwane… Ga re Tshamekeng (Mantlwane Let Us Play) based on a game she played as a child. “Mantlwane was a game I played as a child. It helps to build your imagination, it moulded who I am today. Children have so many distractions today that we are losing that ability to build whole worlds.”Travel while standing stillGrowing up in Thaba ‘Nchu, Mrwebi was a voracious reader. She has often spoken about how reading allowed her to travel the world without leaving her home. “There was one library in Thaba ‘Nchu and no mall. The first time I even heard about this thing called a mall was in a book. That is an important lesson I share. It does not matter where you come from, the world does not need to be a mystery. Or strange.”But she yearned to find books written in Setswana, her mother tongue, about her own experiences. She believes it’s important to read, and write, your own literature. Writers, she says, think and dream in their mother tongue and something is lost when it is translated. Desperate to share her culture with the world, she has self-published four books in her mother tongue. “In the mother tongue a writer’s message is clear. In translation, something is lost.”The desire to get more mother tongue books into print was the acorn that grew into Charmza Literary Club, her publishing business. Charmza is, as she explains, one house with many rooms that include publishing, her storytelling school visits, her poetry workshops and the work she does with the Performing Arts Council of the Free State.“When I published my first book I thought book stores and distributors would jump to stock it. When that did not happen, I needed to create a platform to distribute my book so I created Charmza. I’ve got my books and the authors we publish out because we needed to learn how to be persistent and innovative.”She is hopeful that, like her, there is a young Setswana writer who will be inspired to tell their own story. And who is Mrwebi inspired by? There is her grandmother of course, Ellen Kuzwayo, author of Call Me Woman.Without missing a beat, however, she says Buchi Emecheta, the Nigerian author of The Bride Price and The Joys of Motherhood. “Despite all her challenges – a single woman in a foreign country; raising four kids. Unemployed. She rose above it all. Her writing, her love of books lifted her up.”Would you like to use this article in your publication or on your website?

Proposals such as bringing out textbooks in two volumes, following a flexible timetable and starting a pilot project to provide tablets in classrooms is being considered by the government.Final decision awaitedAs per HT report, the official said, “A number of suggestions were given to reduce the burden of schools bags, which is also a long-standing demand of parents and students. All the suggestions will be considered by the ministry and a final decision will be taken soon.”Sources further said the move will impact government as well as private schools.(Read: CBSE will scrap marks moderation policy for Class 12 only if state boards agree)”The minister is quite concerned about the issue and a number of suggestions were also given by Central Board of Secondary Education (CBSE) such as asking schools to follow a flexible timetable, installing RO for water so that students do not have to carry water bottles and allowing students to wear sports shoes to school as they have to carry it separately for games period,” he said. “This plan is at a preliminary stage and requires more discussion. All stakeholders will be consulted before a decision is taken regarding books,” the official added.On the basis of a report which the National Council of Educational Research and Training (NCERT) will prepare, a final decision on the ones to be adopted will be taken by the ministry.advertisementCirculars are being issued to schools on a regular basis by the CBSE in which they are asked to make sure that students up to class 2 are not required to bring school bags.

When asked if he would allow Davies to move in the New Year, Silva replied: “No way. Impossible. No way. Tom is part of our squad. He is an important player for me and an important player for us as a club. He is the present and the future of our club.”I know Tom is not playing the last few games but that is not his fault. It is because the players in that position are playing very well. When I changed to start with Andre (Gomes) for the first time against Crystal Palace, Tom’s performances were improving.”He did very well in the game before at Leicester but I took the decision to change – not because of Tom’s performance but because of how I expected Crystal Palace to play, and they did play that way.

Procurement Regulations Passed in Senate

first_img Leader of Government Business in the Senate, Hon. Kamina Johnson Smith, said a third, the Public Procurement (Registration and Classification of Suppliers) Regulations, 2018, is expected to be tabled at a later date. Story Highlights The Public Procurement Regulations 2018 and the Public Procurement (Reconsideration and Review) Regulations were approved by members of the Senate on July 13. The regulations are linked to the Public Procurement (Amendment) Act, which was passed by both Houses of Parliament earlier this year. The Act seeks to regulate the procurement of goods, works and services by entities of government. The Public Procurement Regulations 2018 and the Public Procurement (Reconsideration and Review) Regulations were approved by members of the Senate on July 13.Leader of Government Business in the Senate, Hon. Kamina Johnson Smith, said a third, the Public Procurement (Registration and Classification of Suppliers) Regulations, 2018, is expected to be tabled at a later date.The regulations are linked to the Public Procurement (Amendment) Act, which was passed by both Houses of Parliament earlier this year. The Act seeks to regulate the procurement of goods, works and services by entities of government.“The third requires the establishment of the new Commission, and that will only happen after these regulations are passed and the Act comes into force,” she said.Senator Johnson Smith said both regulations are formulated pursuant to section 60 of the Act and intend to prescribe provisions, procedures, standards and criteria for the various methods and subject matter of procurement; the establishment, management and operation of an electronic procurement system; overall bidding proceedings; and an appeal mechanism.“The ones not yet before us are those that will consider issues which are often of concern to suppliers, so those are the concerns related to the forms, the fees and procedures for the registration or classification of suppliers, the evaluation criteria for qualifications required for the registration and classification of suppliers, and the circumstances under which registration under the Act may be modified, suspended, cancelled, approved or withdrawn by the new Public Procurement Commission,” she explained.Senator Johnson Smith said in addition to codifying the rules, the regulations seek to build institutional capacity to ensure continuity in the levels of practice of modern procurement.She added that the regulations also outline the procedures for refusals and reviews of procurement applications.last_img read more
