Limitation of size by hypoxia in the fruit fly Drosophila melanogaster

first_imgThe size of an organism is of fundamental importance in all biological processes. It dictates many of the critical interactions and physical factors that delimit the envelope within which an organism can grow. We investigated the effects of reduced oxygen on size and development in the fruit fly Drosophila melanogaster, and showed that limiting the oxygen in the environment limits both whole animal and cell size. When oxygen levels were reduced from 20% in nitrogen to 15%, 10% and 7.5%, there was a linear decrease in both male and female mass. Both cell size and cell number decreased in low oxygen, but changes in cell size accounted for a larger proportion of the overall change in fly size. Cell numbers decreased by a maximum of 11% between flies reared in 20% oxygen and those reared in 7.5% oxygen, whereas cell surface area decreased by 17%. Low oxygen levels increased development time and mortality, but reduced fecundity. Reducing the level of oxygen available significantly slowed development times, with flies reared in 10% oxygen emerging on average 1.5 days later than those in 20% oxygen. The effect of oxygen on size is reversible during embryonic and larval development up to the pupal stage, when final size is set.last_img read more

HMCS Summerside Sets Sail for Arctic

first_img View post tag: Deployment Her Majesty’s Canadian Ship (HMCS) Summerside departed on July 29th from Halifax, N.S. for Canada’s arctic, where she will be joined later in August by HMCS Shawinigan. This deployment is a part of a 39-day mission north of the 60th parallel, marking the Royal Canadian Navy’s (RCN) longest uninterrupted arctic naval presence in recent years.During the deployment, HMCS Summerside and HMCS Shawiniganwill participate in Operations QIMMIQ and NANOOK, conducting surveillance and presence activities, as well as joint training scenarios, showcasing Canadian Armed Forces assistance to civil emergency management and law enforcement agencies during threats to public safety.“Overcoming the challenges associated with operating in Canada’s northern regions is an important area of focus for the Canadian Armed Forces. Accordingly, we will continue to play a key role in supporting Canada’s Northern Strategy,”said General Tom Lawson, Chief of the Defence Staff. “With these ship deployments the Royal Canadian Navy will, alongside other government departments, establish a visible and important federal presence in our northern communities during the next two months. The ships will also be pre-positioned to participate in our largest annual northern training and sovereignty activity, Operation NANOOK.”“The deployment of maritime coastal defence vessels in Canada’s northern waters serves as an example of how our Navy demonstrates sovereignty in the North and, when authorized, assist other government departments in enforcing national and international law,” said Vice Admiral Mark Norman, Commander of the RCN. “The experience will also help us prepare the stage for more extensive operations in the ice, to be conducted in the future by our Arctic and Offshore Patrol Ships, by ironing out some of the logistical and operating challenges generated by the sheer distances, remoteness, and generally harsher environmental conditions in the North.”Operation NANOOK, the most widely recognized of all the northern deployments, and Operation QIMMIQ, a year-round persistent surveillance and presence operation, are directed by Canadian Joint Operations Command. Other yearly Northern deployments include the springtime Operation NUNALIVUT in the high Arctic and the summertime Operation NUNAKPUT in the western Arctic.[mappress]Press Release, July 30, 2013; Image: Canadian DoD View post tag: Navy View post tag: HMCS View post tag: Defense View post tag: Canada View post tag: Summerside View post tag: Arctic July 30, 2013 Share this article View post tag: News by topiccenter_img View post tag: Naval View post tag: QIMMIQ View post tag: NANOOK View post tag: sets View post tag: sail View post tag: Defence View post tag: Shawinigan HMCS Summerside Sets Sail for Arctic Back to overview,Home naval-today HMCS Summerside Sets Sail for Arctic last_img read more

Warm May Weather Could Drive June Electric Bills Upward

first_imgFacebookTwitterCopy LinkEmailShare With summer temperatures arriving earlier than usual, Vectren is encouraging customers to consider the likely increase in bills received in the month of June, which reflect May consumption. During the month of May, temperatures were higher-than-normal for spring, which have caused customers to start utilizing their air conditioners and cooling fans earlier than usual.“May was significantly warmer than normal and has undoubtedly caused customers’ cooling systems to run earlier and more often than last spring,” said Brad Ellsworth, president of Vectren Energy Delivery-South. “The early start to summer is certainly driving energy usage and bills higher. We are encouraging customers that may find themselves with a higher than expected bill to reach out to us before they have an issue with paying their bill.”Bills received in June, which reflect May usage, are expected to be higher on average than bills received last month, which reflects a more seasonably appropriate month of April. Customers who may be challenged to pay or those who have received a disconnect notice should call Vectren at 1-800-227-1376 to see if they qualify for a payment arrangement, where the bill amount can be spread into smaller payments over a set period of time.Customers are reminded to consider ways to conserve energy, which will help reduce summer energy bills this season. Vectren offers a variety of energy-saving tips as well as information on additional energy efficiency programs for residential and business customers on its website.

Soda bread solution

first_imgThink of the most difficult-to-handle dough, batter or mix your bakery has to deal with on a daily basis. Flapjacks may spring to mind but, for many, soda bread tops the list.Combine cold, fresh Irish buttermilk, with extra coarse wholemeal flour, wheat flour, bread soda, salt and wheatgerm and the result is best described as being like porridge. Scale up to industrial quantities and you need plant and equipment that is up to the job.One of the main Irish producers of soda bread is McCambridge (Rathcoole, Co Dublin). Established in 1985, the company is a wholly Irish-owned food manufacturer that has history of food production going back to 1945. It started baking in 1994 and also still produces a variety of luxury cakes, puddings and ice cream, in addition to speciality breads.The recipe for its best-selling Irish Stoneground Wholewheat Brown Bread has been in the family for generations and it gives the product a distinctive nutty texture and taste. The product is yeast-free, low in fat, high in dietary fibre and has no added sugar. British consumers can now buy it over the internet in cases containing eight loaves at £15.60 per case.In April 2005, McCambridge bought Gills bakery and, following a strategic review of operations, decided to move all soda bread production to the Gills site, seeing great market opportunities for soda bread produced in a modern plant on purpose-built production lines. Managing director Michael McCambridge takes up the story: “We took a long hard look at the market and, with the help of a third party consultant, decided the time was right to invest in its future.”We had previously worked with European Process Plant (EPP) and purchased a small amount of packaging plant from them. After talking to a number of other suppliers we were very impressed, not only with the equipment EPP could supply and support, but with its overall approach to the project, particularly the partnership attitude employed.”McCambridge decided on an automated VMI double-spiral, three-bowl carousel mixing system. “This not only offered us the capacity but, perhaps more importantly, the mix consistency we were seeking,” explains McCambridge. “A very gentle mix is a prerequisite for a quality end product.”The machines have been designed by VMI to be robust as well as efficient, says EPP. Every carousel system is individually specified, including the mixer and tool type, as well as the number of ingredients’ feeding stations, mixers, bowls and bowl elevators. VMI systems can be full integrated with both the upstream – silos, small ingredients systems – and downstream equipment, including dividers and depositors, says the firm.Soda bread has very different production requirements to yeast plant bread and, for an installation of the size required by McCambridge, it was imperative that every detail was correct. Take, for example, the ovens. When baking soda bread there is no need for a turbulent air flow in the ovens and the product needs to be placed in heat as quickly as possible after mixing for the 10-12-minute bake. Get the baking profile wrong, and the loaf will burst open.RADIANT HEATEPP did its homework and liaised closely with engineers at Gouet, designer of the 18m-long Cyclothermic tunnel oven that is the centrepiece of the production line. The oven is easy to use and, importantly, easy to learn. It uses purely radiant heat to achieve the best possible quality. Even heat distribution is critical to achieving consistent product colour, shape and eating quality. The airflow through the heat exchangers, ducting and radiators in the oven is optimised to achieve this.The oven is divided into six zones and has two separate burners/heat exchangers to enable maximum adjustment of the baking temperature curve as the products travel through the baking chamber.EPP also supplied the tray conveyors to link everything up and an automatic tray stacker to store trays and to maintain a constant feed of trays through the plant. In consultation with EPP, a needle depanner was specified – perhaps to the surprise of some. The system was chosen in preference to a vacuum depanner, as it is quieter in operation, more energy-efficient and more reliable, with 100% of the product being depanned.LEAP OF FAITHMichael McCambridge admits that, in many ways, it required a great leap of faith on his part to put his trust – and money – in EPP and VMI and Gouet. But on the day the new oven was fired up in the Rathcoole Bakery, beyond the expectations of all involved in the project, the very first product put through the oven was 90% right and it was not long before what McCambridge describes as the “sweet spot” was found and full-scale production could begin in earnest.The order for the equipment was placed in November 2005 and, by the following July, soda bread was continually cooling on the newly installed spiral cooler before being placed in resealable Freshgard packaging, ready for despatch. The new plant has improved production efficiency in terms of the number of people required, as well as reducing energy consumption.McCambridge Group is also expanding in the UK. It now owns Husseys Bakery in Berkshire, Queen of Hearts cake supplier in Oxford as well as West of England Bakeries based in Plymouth. nlast_img read more

Bakers not government should decide how extra skills funding is spent

first_imgThe baking industry should be allowed to decide how new funding for skills, recently announced by government, should be spent, as the head of the UK’s food and drink sector skills council accused the government of “clinging onto the purse strings”.Improve chief executive Jack Matthews welcomed the government’s pledge of an additional £260 million, but criticised the ringfencing of the funding for only training under-25s, stating that funding for skills would only work if it was left to industries to decide where it should be deployed.Individual sectors including bakery were in “dire need” of direct assistance to help fund solutions to training and skills shortages, he added.Matthews also argued that “rapid-response” strategies were needed to retrain and relocate workers in areas where their skills were needed. “This can’t happen while the government clings onto the purse strings and attempts to micro-manage where funding is allocated,” he said.Justine Fosh, director of the National Skills Academy for bakery, said: “The funding available for training is tightening and often being redirected towards these kinds of generic initiatives [under-25s training]. The profile of the workforce is largely older in the bakery sector, so this initiative misses the target. There’s a need to ensure the bakery sector has a skilled workforce that will help drive it forward.”Matthews also urged the baking industry to train those older workers coming onto the labour market who had lost their jobs or who were seeking a career change, and not just young people.last_img read more

Mempho Shares “All-Stars” Audio Feat. Oteil Burbridge, Robert Randolph, Eric Krasno, & More

first_imgIn October 2017, Mempho Music Festival celebrated its inaugural year with the ultimate festival-closing set, comprised of a group of world-class musicians, dubbed the Mempho All-Stars. The late-night super jam was dedicated to three fallen Southern-rock greats who passed away earlier in the year: Allman Brothers Band founding members Gregg Allman and Butch Trucks, and celebrated “granddaddy of the jam band scene”, Col. Bruce Hampton.Led by decorated guitarist Eric Krasno (Soulive, Lettuce), the rotating cast of musicians included bassist Oteil Burbridge (Dead & Company, Allman Brothers Band), guitarist Steve Kimock (RatDog, Phil Lesh & Friends), harmonica player/vocalist John Popper (Blues Traveler, Frogwings), steel guitarist Robert Randolph (Robert Randolph & The Family Band), drummer/percussionist Jeff Sipe (Aquarium Rescue Unit), drummer/percussionist Wally Ingram (Timbuk 3), guitarist Papa Mali (7 Walkers), DJ Logic, banjo/vocalist Rev. Jeff Mosier (Aquarium Rescue Unit, Blueground Undergrass), guitarist Eric McFadden (P-Funk Allstars, Stockholm Syndrome, Anders Osborne), vocalist Leslie Mendelson, keyboardist Peter Levin (Gregg Allman Band), keyboardist JoJo Hermann (Widespread Panic), vocalist Lamar Williams Jr. (Les Brers), bassist Tad Kinchla (Blues Traveler), and bassist MonoNeon.The setlist featured staple numbers from the Allman Brothers Band, Col. Bruce Hampton, and Gregg Allman, as well as classic covers by Al Green and Otis Redding and, of course, a set-closing rendition of “Turn On Your Lovelight”, the cosmic curtain call from Col. Bruce’s stranger-than-fiction sendoff. The 2+ hour celebration was the perfect way to close the festival, and today, you can listen to the full show audio, mixed and mastered by the legendary Terry Manning (Stax/Ardent), whose resumé includes work with Led Zeppelin, Al Green, Otis Redding, Joe Cocker, Lenny Kravitz, Widespread Panic, and many more.The “Mempho All-Stars” late-night super jam was produced in benefit of Mempho Music Festival’s philanthropic program “Learn to Rock,” which aims to build bridges throughout the Memphis community by educating students about the city’s rich musical history. As part of the program’s outreach, Learn to Rock—sponsored by Orion Federal Credit Union—provided hundreds of free tickets to Shelby County Schools high school students, staff, and family members, as well as the Soulsville Foundation/Stax Academy and the Memphis Music Initiative.Mempho Music Festival, a two-day music, food, and camping experience, will return to Shelby Farms Park in Memphis, TN on October 6 & 7, 2018.

‘Inside/Out’

first_imgThe 1910 class notes for the all-woman Garland School of Homemaking in Boston were titled “Times Where We Need the Man.” The list of gendered chores now seems antiquarian: chop wood, sweep ashes, care for horses, and bring in coal.But one chore still sounds familiar. It reads: “wash windows (?)”That question mark, a sign of the longstanding tug-of-war over housework, survived the past century intact. But relations between American men and women have changed a great deal — and are still changing.One aspect of ever-shifting gender relations is being explored this semester at the Radcliffe Institute for Advanced Study: space, that wide realm of interiors and exteriors that marks the social commons — that is, everything outside our bodies. How are men and women negotiating access to space? And how have those negotiations changed over time?In mid-April, Radcliffe will sponsor “Inside/Out: Exploring Gender and Space in Life, Culture, and Art,” a two-day international conference of artists, architects, researchers, legal scholars, and sociologists. It’s part of an annual series of Radcliffe spring conferences on gender that have explored war, food, and other points of intersection between the sexes.The conferences are usually accompanied by an exhibit in the Arthur and Elizabeth Schlesinger Library on the History of Women in America, and “Inside/Out” is no exception. “Inside/Out: The Geography of Gendered Space,” by turns grave and whimsical, is on display through October.The exhibit is in four parts, each representing a realm within space: private, public, political, and artistic. The categories are derived from feminist scholar Kerstin Shands, who sees two types of gendered spaces. “Bracing” spaces represent resistance, and “embracing” spaces imply empowerment and safety.In the “private” section of “Inside/Out,” there are documents, magazines, books, and photographs that illustrate what for centuries was regarded as a woman’s exclusive purview, the household.The 1910 class notes are there, in looping old-fashioned handwriting. So are fragile issues of 19th century magazines, with titles such as Mrs. Mayfield’s Happy Home (1877) and The Mother at Home and Household Magazine (1864).On display in the same case are passages from books that express the exclusivity — and confinement — of a woman’s household dominion. In her 1875 novel “We and Our Neighbors,” Harriet Beecher Stowe, the author of “Uncle Tom’s Cabin,” offers up a passage that would make a modern-day Eliza flee across the ice to escape the slavery of gender: “Self begins to melt away into something lighter,” she wrote of women kept inside by social norms. “Her home is the new personification of herself.” A passage from “Art in the Home” (1879) goes further, by modern standards, declaring that a woman “should be herself the noblest ornament of her ornamental dwelling.”For 19th century women who were uncomfortable being ornaments, there was travel, or even living alone in cities, a set of spaces explored in the exhibit’s “public” section. In cities, women could take on nontraditional roles, said the exhibit notes. Lynn, Mass., entrepreneur Lydia E. Pinkham (1819-1883) did well, turning her home remedy for “female maladies” into the most popular patent medicine of the age.But urban spaces were also segregated by gender. An engraving from the July 21, 1875, Illustrated London News pictures a “ladies” window at a New York post office. “I just love the image of going to a post office and having their window be for me,” said Schlesinger executive director Marilyn Dunn, with a laugh. “It captures the idea of gendered space.”In the same display case is a note on the Women’s Hotel in New York City, which opened in 1878, offering a week’s board and lodging for $6. The Barbizon, a more contemporary women-only hotel, was profiled in a 1963 issue of the New York Evening Post. The headline was “Where the Boys Are Not.”Where the boys are not is also a theme in the “artistic” section of the “Inside/Out” exhibit. There’s a photo of Judy Chicago and Miriam Schapiro, co-founders of the California Institute of the Arts Feminist Art Program, at “Womenhouse.” The 1971 art installation, set up in a deserted Hollywood mansion, featured the work of only women, and men were banned from the opening.But the same section in the exhibit shows that the art world was often where the boys were and the women were not. On display is a 1985 banner from the Guerilla Girls, an anonymous group of feminist artists formed to protest a Metropolitan Museum of Modern Art show. Of the 169 artists represented, they complained, only 13 were women.The banner, a spoof on an odalisque-like nude, also claimed that while 5 percent of the artists were women, 85 percent of the nudes were. “Do women have to be naked,” the banner asked, “to get into the Met. Museum?”“Inside/Out” offers a glimpse at the feminist pioneers of the art world, including sculptor Harriet Hosmer (1830-1908), who was born in Watertown, Mass. She sculpted “The Sleeping Faun,” a male figure whose softened musculature rewrote the standards of masculine display. Hosmer’s plaster model of “Queen Isabella of Castile” — monumental and imperial — was intended to show that the queen was the equal of explorer Christopher Columbus, whose iconic journey she helped to sponsor.The sculptor “was very much interested in female heroism,” said Schlesinger operations manager Bruce Williams, who co-chaired the exhibit committee.An 1861 photograph shows Hosmer — elfin, pugnacious, and defiant — in the center of a group of rough male artisans in Italy. On the back, the inscription reads, “Hosmer and Her Men.”Then there is that sphere that is more familiar — or at least more dramatic — than the others: “political” space. This section looks at “sites of resistance,” said Williams, including the parades, protests, sit-ins, and other events that demanded expanded access for women in social and physical spaces.Protest is on display, in the video touch-screen portion of “Inside/Out,” including black-and-white footage from a stormy 1970 takeover of the New York offices of Ladies’ Home Journal by feminists. The magazine’s editorial policy, they said, kept women in the confining grooves of “children, kitchen, and church.”One joyful photograph, a line of women at the front of a protest march, is from the opening of the 1977 National Women’s Conference in Houston. Prominent in the picture are Betty Friedan, author of “The Feminine Mystique,” and Bella Abzug, a New York lawyer, activist, and congresswoman. Abzug is famous for her defiant pun: “This woman’s place is in the House — the House of Representatives.”“Inside/Out: Exploring Gender and Space in Life, Culture, and Art” will be held April 15-16, Radcliffe Gymnasium, 10 Garden St. Free and open to the public, registration is required. Deadline to register is April 5.Also in conjunction with “Inside/Out,” the Harvard University Graduate School of Design presents the exhibition “Inhabit” by independent artist and “Inside/Out” conference panelist Janine Antoni. “Inhabit” will be on display from March 22 to April 16 in Gund Hall, 48 Quincy St., Cambridge, Mass.last_img read more

Amid backlash, Harvard cancels class on policing strategy

first_imgCAMBRIDGE, Mass. (AP) — Harvard University’s engineering school has canceled a class that intended to evaluate a policing strategy based on U.S. military tactics after students raised concerns about the strategy’s impact on people of color. In a message to students on Monday, the school’s dean said the class had been withdrawn and officials plan to review the vetting process for proposed classes. A course description said it would ask students to analyze data on a policing strategy based on counterinsurgency tactics used by the U.S. military. A petition from students said it failed to consider the disproportionate impact of such policing on Black and brown communities.last_img read more

The Trial Gardens at UGA

first_imgOver the last three decades the Trial Gardens at UGA have introduced home gardeners and landscape designers to thousands of new plant varieties. The public will have the chance to get a first look at this year’s new varieties and some tried and true Georgia favorites at the gardens’ annual public house on July 12 from 9 a.m. to 1 p.m.Every year at the Trial Garden’s open house, visitors get an up close and personal look at a new class of vetted ornamentals — ranging from gorgeous flowers to hardy shrubs. Dozens of new perennials should be in bloom during this year’s open house, in addition to a show-stopping array of roses and the garden’s 2014 rotation of annuals, said UGA horticulturist John Ruter, director of the Trial Gardens. “The Trial Gardens at UGA are one the best kept secrets in northeast Georgia,” Ruter said. “Our annual open house is our chance to share one the most beautiful parts of the UGA campus with the community and share some of what we’ve learned over our last year gardening.” Located on the UGA campus in Athens, Ga., between the Snelling Dining Hall and the R. C. Wilson Pharmacy Building, the gardens display hundreds of annuals and perennials from plant breeders around the world. The open house will showcase some advanced selections from Ruter’s breeding programs as well as many less-known selections. The garden is always open to the public, but the open house gives visitors inside knowledge about this year’s most promising plant varieties. Ruter will give tours of the garden throughout the day focusing on some of the new additions to the garden. This year marks Ruter’s first at the Trial Gardens at UGA, and he looks forward to highlighting his first crop of test plants. “We have some petunias that have done fantastic this spring and a large selection of Madagascar periwinkles that should be in bloom for the open house,” Ruter saId. Plant nurseries and breeding companies send hundreds of new plants each year for evaluation in the garden. They need to know if their plants can survive the hot and rainfall-variable Southeast. The companies fund the garden by paying to have their plants evaluated by an unbiased source. That money pays for the gardens’ upkeep and a team of student workers who keep the garden running. The event will be held rain or shine, and the garden staff requests a $5 donation to help offset the cost of the event and support the garden. The Trial Gardens also serve as a teaching and research facility for the UGA Department of Horticulture and other academic departments. Parking is available in the South Campus Parking Deck, and the gardens are located at 220 W Green St., Athens, Ga., 30602.
