Middle Jurassic within-plate granites in West Antarctica and their bearing on the break-up of Gondwanaland

first_imgFive post-tectonic granitic plutons isolated within the central Ellsworth-Whitmore mountains crustal block in West Antarctica form a distinctive geochemical suite. All have some characteristics of S-type granites and are atypical of active continental margins. They range in composition from a within-plate granite (WPG) end member, with the lowest 87Sr/86Sr initial ratio (0.707), to granites with a much more marked crustal signature and high initial ratios (0.722). The granitic suite was emplaced over a restricted Middle Jurassic time interval at the same time as the extensive Ferrar-Karoo-Tasman mafic suite and just prior to the disintegration of the supercontinent Gondwanaland. Petrogenetic modelling suggests that the WPG end member could have been derived entirely by differentiation of the enriched mantle-derived Ferrar magma, and the end member with the highest initial ratio by partial melting of a crustal source. Low initial 143Nd/144Nd ratios and Proterozoic model ages are compatible with a Precambrian crustal component but may alternatively, as in the case of Ferrar Supergroup magmas, reflect partial inheritance from enriched lithospheric mantle geochemically coupled to the lower crust since Precambrian differentiation. Data from these granites are consistent with large-scale underplating of mafic magma and crustal melting in response to a thermal disturbance in the Gondwanaland lithosphere related in some way to break-up of the supercontinent.last_img read more

Pizza the action

first_imgWhether they’re going posh in Pizza Express or casual in Pizza Hut, having it delivered, taking it away, buying it from the freezer or chiller of a shop or even making their own, seven out of 10 people in the UK are eating pizza, according to research company Mintel.The world of pizza is clearly a world of opportunities and options for the consumer, before you even start discussing bases and toppings. So is it a saturated market that bakers would do well to avoid?Well no, Mintel suggests that there is also room to increase frequency of consumption in pizza. When it compiled its last report in 2008, half of adults who ate pizza only did so once a month at most.And rival research company Euromonitor argues there is still significant mileage for foodservice operators and independents, including bakers, to cash in, taking sales away from the established brands and the supermarkets. But you have to pitch it right and the growth in the market is coming from premium offers, says the company.Look for example at Gondola Holdings, which operates the upmarket PizzaExpress, ASK and Zizzi brands. It has seen sales rise steadily over the last five years as demand increases for its pizzas despite the economic gloom.The group favours fresh ingredients and a thin crust base, offering something close to the traditional authentic Italian pizza experience, rather than the American pizza experience.Rival and more “value” operator Pizza Hut, owned by Yum! Brands, says it has recently introduced thinner crust Tuscani pizzas, in a change of direction from its promotions-orientated approach, although Chicken Supreme, Pepperoni Feast, and Vegetable Supreme remain its best selling pizzas.Meanwhile, the key takeaway operator is Domino’s Pizza, which has 571 UK outlets. It says it is focused on consumer convenience such as online and mobile phone ordering. The goal is to make its offer more convenient for the consumer than putting a packaged pizza in the oven. Sales were up 10.5% for the first quarter of 2010. Its best selling topping is Pepperoni Passion.Jason Bull sales director of supplier Eurostar Commodities comments: “I feel the pizza market as a whole is still in growth, due to the demand for higher quality and authentic ingredients such as genuine 00 Italian flours for pizza bases. Manufacturers are getting much more creative in this very tough environment, to set themselves apart from others and provide a competitive edge.”He says he hopes to spawn a new age of pizzas that are good for your health with two products due to launch this month. These are Gran Fibre, a high fibre, low fat cereal flour mix, and Pane Rustici.Unique selling pointIn a crowded marketplace it is harder for operators to find a unique selling point and make their pizza offering stand out, comments Warren MacFarlane, marketing manager at dairy group Lactalis McLelland.”One way to achieve this is to make your pizza taste as authentic as possible. Here the use of genuine Italian toppings and ingredients is a must, such as our range of Galbani Italian cheeses.”Operators looking to add a touch of class to their menu should consider tasting our PDO (Protected Designation of Origin) cheeses,” he suggests. “With customers’ perception of quality versus value for money being higher than ever, operators need to offer premium products. Using PDO Italian cheese on menus will clearly illustrate their point of difference in a crowded market. Why not advertise the fact your menu contains cheeses that come from a particular region in Italy, and add real gravitas?”Bakers have another advantage when it comes to gravitas. A skilled baker should easily be able to make a decent pizza base.And for the bakery operator, pizzas can in fact be an extremely cost effective sideline. Pizza dough is relatively cheap and simple to make – even if you are using top quality grains. What’s new? Sunspice Oils What are Sunspice Oils?A collection of oils flavoured with herbs and spices, including garlic, onion, oregano and basil. Sunspice Collection oils are intense and offer an easy way to bring the character of fried herbs and spices to pizza bases, toppings and breads. They are heat-stable, simple to use and a natural means of giving dishes an authentic flavour profile.What’s so special about them?The Sunspice flavours enable the full, cooked flavour of fried herbs and spices to be integrated into a dish, without the need for high heating of other ingredients. This preserves nutrients and significantly boost the impression of freshness in the finished product.Why should manufacturers buy this?The Sunspice Collection can help manufacturers create products with premium and gourmet positionings, focusing on the quality and provenance of ingredients without the storage and food safety issues associated with fresh or frozen herbs and spices.So explain the techie stuff.Manufactured by Symrise, Sunspice is created by frying the culinary ingredients in vegetable oil. They are free of added flavour enhancers, dyes, and GM ingredients and can be declared either as natural flavours or as the individual herb or spice.Bottom line, what’s the benefit to the manufacturer?The oils are simple to use, mix and meter, and offer an easy way to flavour food compared to fresh herbs and spices no frying necessary.Questions posed to Alie Coppolella, technical manager, S Black Product Update Touch pad controlLincoln Countertop Impinger ovens from Manitowoc Foodservice UK now come with a digital touch pad as a standard feature on the front of the oven.The new push-button control panel gives operators the ability to quickly and easily set conveyor direction, speed, and temperature. The new controls also feature four preset menu buttons with digital time and temperature display. The oven incorporates a 16-inch wide conveyor belt and 20-inch baking chamber and can be stacked up to two high. In most applications ventilation is not required.The updated model now includes a more robust conveyor motor, a broader range of oven temperatures from 32ºC to 315ºC and a wider range of conveyor speeds.Take it to the topping Rectory Foods, global supplier of quality poultry and food ingredients, has launched a new range of frozen chicken products for the bakery sector under its Hot Chicken Company (HCC) brand. The company says that chicken is a good value source of protein for bakers and baked goods manufacturers to create a variety of pizza toppings that customers know and love, from the traditional to more inventive products. Nick Bowyer, MD at Rectory Foods, comments: “Chicken toppings are not only filling for hungry customers, but are often viewed as healthier than red meat or pepperoni alternatives.”The HCC range features frozen, steam-cooked, roast or flavoured premium chicken breast pieces. These are available in strips (10/12mm), slices (5mm) and cubes (10/12mm) and are ideal for bakers to add to a range of dishes, from fresh pizzas, sandwiches, baguettes, paninis, bagels, wraps and croissants, as well as pies. Keeping a lid on sauce Decorating lines providing a wide range of options for both edge-free and total coverage pizzas are a speciality of the Tromp group. Edge-free decorating systems ensure that sauce and toppings are contained within a specific area of the base, says the Shrewsbury-based company. They feature automatic positioning of pizza bases on foam or cardboard discs, and a servo-driven sauce depositor designed so that herbs and pieces can be included. An equalizer spreads out the sauce before a target applicator adds cheese, meat, fish and vegetables. A continuous line for total coverage of the pizza base is modular to allow for extension. A waterfall enrober applies a constant, controlled layer of sauce, then a continuous strewing system adds a full selection of toppings onto any pizza shape, with a re-circulating system minimising waste.These sophisticated systems feature a sensor driven pizza tracking system. All parameters can be adjusted on a single touch-screen, and saved for recall on the next production run.last_img read more

Grateful Dead Played Their Final Show At The Fillmore East On This Day In 1971 [Listen]

first_img48 glorious years ago today, the Grateful Dead took the stage at New York City’s Fillmore East for the final time.The Dead were no strangers to creating magical moments at the Fillmore East, which at that time was being booked and operated by Bill Graham. Just two nights prior on April 27th, the Dead welcomed members of The Beach Boys to the stage to help play on a mix of songs during the second set. On this night, the Dead needed no special guests to get the intimate venue rocking with two sets of music filled with songs from their then-new studio albums, 1970’s Workingman’s Dead and American Beauty.The band started their lengthy performance with high-energy renditions of “Truckin’” and “Bertha”, followed by “It Hurts Me Too”. The first set would go on to be filled with early-Dead live favorites, including “Cumberland Blues”, “Me and My Uncle”, a 12-minute “Bird Song”, “Playing In The Band”, and “Casey Jones”. The highlight of the first set was the band’s nearly eight-minute performance of “Ripple”.The second half of the show was filled with just as many fan-favorites from the band’s live catalog, including “Morning Dew”, “Sugar Magnolia”, and a cover of “I Second That Emotion”, which they’d played during a handful of shows in April of that year. Other songs that made it into the second half of the show included “Alligator”, “Cold Rain And Snow”, “China Cat Sunflower” into “I Know You Rider”, “Greatest Story Ever Told” (a Bob Weir solo tune which would appear on his debut studio album the following year), and the band’s cover of Chuck Berry‘s “Johnny B. Goode”. The three-song encore consisted of “Uncle John’s Band”, finally closing with “And We Bid You Goodnight”.Fans can relive the band’s 1971 performance via the audio player below. If fans listen closely, they’ll hear Bill Graham making a few surprise trips to the microphone throughout the show.Grateful Dead – The Fillmore East – 4/29/1971[Audio: Jonathan Aizen]Some of the songs recorded throughout the night were included on the band’s 2000 compilation, Ladies and Gentlemen… the Grateful Dead, which featured a mix of recordings captured during the band’s final Filmore East run on April 25th-29th, 1971.Setlist: Grateful Dead | The Fillmore East | New York, NY | 4/29/71Set One: Truckin’, Bertha, It Hurts Me Too (Traditional cover), Cumberland Blues > Me and My Uncle (The Mamas and the Papas cover), Bird Song, Playing In The Band, Loser, Dark Hollow (Bill Browning cover), Hard To Handle, Ripple, Me And Bobby McGee, Casey JonesSet Two: Morning Dew (Bonnie Dobson cover), New Minglewood Blues (Noah Lewis cover), Sugar Magnolia, Black Peter, Beat It On Down The Line (Jesse Fuller cover), I Second That Emotion (The Miracles cover), Alligator > Drums > Alligator > Goin’ Down The Road Feeling Bad (Traditional cover) > Cold Rain And Snow (Traditional cover) > China Cat Sunflower > I Know You Rider (Traditional cover), Greatest Story Ever Told > Johnny B.

Professor reflects on Chavez’s death

first_imgThe death of Venezuela’s President Hugo Chavez on Tuesday leaves a number of questions for the South American nation, which now adds a presidential election to the list of complex challenges it already faces. Professor Michael Coppedge, a political science professor specializing in Latin-American politics and global democratization, said the future of the regime – at least in the short term – will be determined by Interim President and Chavez’s chosen successor, Nicolas Maduro. “A lot of it depends on what Maduro will do now that he’s not in Chavez’s shadow, because he’s been very loyal to Chavez and has hidden his own tendencies to demonstrate absolute loyalty,” Coppedge said. “Now that he doesn’t have to do that, we’ll see what kind of person he is. I expect he’s not a liberal democrat, but whether he’ll be more open [to opposition] … remains to be seen.” Coppedge said Maduro’s initial statements after the president’s death suggest he intends to keep a short leash on opposition, at least in the weeks leading up to the election. “There was a subtext that the opposition better behave itself, that this is not a time to cheer or call for radical change, it’s a time to remember our fallen leader,” Coppedge said. “I think there’s a fear the opposition will try to capitalize on the moment.” The Venezuelan government announced an election will be called within 30 days, and Coppedge said he believes Maduro, the candidate for Chavez’s socialist party, will likely be the winner. “If I were to place a bet right now, I’d say Maduro will probably win, in part with the election coming so close after the death, he’ll get the vote,” Coppedge said. “A lot of Chavistas are out to prove their movement will not fall apart. … I think they’ll be motivated to campaign hard and win.” While Maduro is the likely victor, Coppedge believes the opposition could have a substantial presence in the election. “There are a lot of things for people to be unhappy about, and without Chavez to hold his group together, some of these complaints may lead to divisions,” he said. “Purchasing power has been declining, public services have been declining. … People are not happy with the extremely high crime rate.” Although the opposition stands to benefit from economic conditions, its most prominent leader does not appear to be mounting a power grab. “The opposition will probably be behind Henrique Capriles Radonski, but he has exercised some calming leadership,” Coppedge said. “He hasn’t been a polarizing leader and after Chavez’s death he expressed solidarity with Chavez’s family.” While much is uncertain for the political future of Venezuela, Coppedge said the change in leadership could present new opportunities for the country’s relationship with the United States, which was strained under the Chavez regime. “The Obama administration can act as though this can be a new opportunity to do things differently,” he said. “Obama’s statement was expressing hope for better democracy and stability in Venezuela, so I think the [United States] is going to be happy to talk and send out feelers to see whether relations can be better.” The supply of oil from Venezuela to the United States is unlikely to be disrupted during the transition, Coppedge said. “Venezuela is not in a good economic situation,” he said. “It can’t afford to stop selling oil to the [United States]. It makes economic sense to sell to us because we’re so close and have established relationships.” If Maduro wins the election, Coppedge said he is doubtful relations will improve. “I think it depends on whether Maduro, or whoever the president [will be], is going to use the same tactics as Chavez, which is to demonize the [United States] to build support at home,” he said. “I think Maduro is cut from that mold.”last_img read more

WSJ: ‘The Climate for Coal Just Got Even Chillier’

first_img FacebookTwitterLinkedInEmailPrint分享Wall Street Journal:It’s been a pretty good 18 months for the coal industry following the disastrous price crash of 2015, but on Tuesday miners got a big lump in their stockings.BHP, the world’s largest mining company, announced it is reconsidering it’s membership in the U.S. Chamber of Congress, a skeptic on the latest global climate deal brokered in Paris, and may quit the World Coal Association, the industry’s lobby group. BHP cited the WCA’s support for abandoning Australia’s proposed Clean Energy Target as one reason for its preliminary decision to bow out.BHP’s action is largely symbolic but it still smarts coming from one of the grande dames of the mining world. It also comes as Rio Tinto, BHP’s big rival down under, is rapidly selling down its coal assets.The move is, of course, partly about public relations. But big companies like BHP and Rio ultimately make their decisions based on the bottom line, and BHP’s latest move is another sign that the business case for coal as a power-generation fuel is rapidly weakening—despite efforts by the Trump and Turnbull administrations to prop it up.Nearly 20% of BHP’s earnings before interest, taxes, depreciation and amortization (Ebitda) in fiscal year 2017 came from coal, and return on capital employed was a healthy 23%, higher than for all its other major commodities except iron ore. But most of that juice comes from metallurgical coal—used to make steel—and not thermal coal for power generation. BHP estimates that every $1 change in met coal prices will move its 2018 Ebitda by $43 million, compared with $18 million for every equal change in thermal coal price.Both types of coal, like most commodities, have done well in the past two years—roughly doubling in price since the end of 2015. But their outlooks are radically different. Large quantities of met coal will be needed for the foreseeable future for steel production, and good alternatives are lacking. Thermal coal, on the other hand, must compete for power-sector market share in a world awash in cheap natural gas and ever cheaper renewables.More ($): The Climate for Coal Just Got Even Chillier WSJ: ‘The Climate for Coal Just Got Even Chillier’last_img read more

Helping Children Who Flee Venezuela to Stay in School

first_imgBy Share America October 02, 2019 Enrollment in kindergarten through 12th grade in Venezuela fell by 2 million children between 2016 and 2018. Some children dropped out of school because of electricity blackouts or food shortages. Many left Venezuela. More than 4 million Venezuelans, including 1 million children, have left for neighboring countries as a result of the Nicolás Maduro regime’s disastrous policies.That is why the U.S. has provided more than $376 million in funding for the Venezuelan regional crisis response including nearly $334 million in humanitarian aid and $43 million in economic and development assistance since the start of fiscal year 2017.Venezuelan children who have left their country face many hardships. Some face obstacles to attending schools in their host countries. The U.S. supports their access to safe education.Education Cannot Wait, an international nongovernmental organization that received $21 million from the U.S., announced in June an initiative to reach 84,500 out-of-school children and adolescents in Brazil, Colombia, Ecuador, and Peru. The program will benefit both Venezuelan and host-country children.Disrupting children’s education brings steep and long-term costs. Research shows that severe and prolonged suffering harms brain development and predicts higher drop-out rates and lower literacy rates. The U.S. humanitarian response through its partners limits the chance that the Venezuelan crisis will create a lost generation of youth unprepared to contribute to society.In addition to providing funding to help children learn, the U.S. has deployed U.S. Navy Hospital Ship USNS Comfort on a five-month mission to Central American, South American, and Caribbean countries to support health care systems accommodating displaced Venezuelans.last_img read more

‘An awful lot of preventable deaths happening right now’ in the Upper Midwest

first_imgIowa Gov. Kim Reynolds has finally given in and required masks under some circumstances, even as both Noem and Burgum refuse. Burgum encourages mask-wearing, saying “You don’t have to believe in covid, you don’t have to believe in a certain political party or not, you don’t have to believe whether masks work or not. You can just do it because you know that one thing is very real. And that’s that 100 percent of our capacity is now being used.” But require the thing he knows is one of the most important measures available to fight the coronavirus? Nope.”There’s an awful lot of preventable deaths happening right now,” the University of Utah School of Medicine’s Andrew Pavia told reporters on Wednesday. At this rate, they’re not only going to keep happening, they’re going to get worse. Meanwhile, over in Minnesota, beds are a limiting factor—just 22 ICU beds are left in the Twin Cities, and the state as a whole is over 90% ICU capacity. That’s with coronavirus rates rising quickly, hospitalizations following along, and a rise in deaths presumably following those—especially if hospitals get overwhelmed.The Upper Midwest, in other words, is a disaster area, and the disaster is the natural one of the pandemic and the one created by Donald Trump and the Republican governors and legislatures of so many of these states barring meaningful public health responses to the pandemic. – Advertisement – – Advertisement –last_img read more

A unique attraction opened in Croatia: Skywalk

first_imgThe lookout point can be reached by the Biokovo road, which leads from the entrance reception of the Biokovo Nature Park, approximately 6 km east of Makarska, to the highest Biokovo peak, Sv. It runs at an altitude of 1762 meters, which makes it the highest paved road in Croatia. The total value of this project is approximately HRK 31 million, of which grants from the European Structural and Investment Funds amount to around HRK 27 million. The rest is financed by the Fund for Environmental Protection and Energy Efficiency and own funds of users and partners – Makarska Development Agency MARA and the Croatian Mountain Rescue Service – HGSS. Landscaping of the Skywalk Biokovo is part of the project ‘New Adrion – Promoting sustainable use of natural heritage PP Biokovo, which is funded by the European Regional Development Fund under the Operational Program Competitiveness and Cohesion 2014-2020, and is the largest and most demanding financially project in the history of the Public Institution “Biokovo Nature Park”. From the Heavenly Promenade, the view is of Tučepi, Podgora and Makarska, the Dalmatian islands of Hvar, Brač, Vis, Korčula, Pelješac, and in particularly nice weather, after the famous Biokovo bora clears the horizon, the view reaches Cape Monte Gargano in Italy. The lookout is located at an altitude of 1228 meters above sea level, on the 13th kilometer of the Biokovo road, next to the info – center. It is a horseshoe-shaped lookout, with a glass base for walking, which in the most convex point in the length of 12 meters covers the cliffs of Ravna Vlaška. The most impressive and complex part of this EU project is the construction of a horseshoe-shaped belvedere outside the cliff with a glass surface for walking called the Skywalk Biokovo. Approximately eight million kuna was invested in the construction of this building and the reconstruction of the existing lookout. The lookout is open to all visitors from Thursday, July 02nd.center_img Photo: For Biokovo Nature Park Plamenko Cvitić Photo: For Biokovo Nature Park – Plamenko Cvitić As part of the lookout, a geological pillar was built – a three-dimensional view of the cross-section of the rocks that formed the area of ​​Biokovo from its inception until today with a geological table of time and a description of the age and type of rocks. The Skywalk, a unique visitor attraction in Croatia, opened in the Biokovo Nature Park.
