Drip dilemma

first_imgBy Brad HaireUniversity of GeorgiaWith a little time, a bit of dye and a good eye, vegetable farmers can learn to grow their crops more efficiently and economically, says a University of Georgia scientist.Vegetable farmers in south Georgia and Florida can grow crops in all seasons because of the subtropical climate, said Alex Csinos, a plant pathologist with the UGA College of Agricultural and Environmental Sciences.A growing practiceOf the 200,000 acres of vegetables grown in Georgia, about 20 percent are grown in raised beds of soil wrapped in plastic, called polyethylene film mulch. And the percentage is growing.The practice allows the farmer to better control the environment for the crop and apply things like fertilizers, pesticides, fungicides and water in a more environment-friendly way.To do this, farmers run a thin hose with small emitters through the bed under the plastic. They then inject this “drip tape” with the materials, which drip out into the bed.Missing scienceBut a major blank in this new method needed to be filled.Because the drip tape was under the plastic and often under soil and emitting colorless materials, nobody could say for sure whether the drip tape got enough of the material to the plant or into the raised bed.How much material should run through the tape? For how long? At what pressure? Is the tape emitting enough materials to effectively cover the bed? The answers could mean the difference between a good crop and no crop at all.The instructions salesmen gave to farmers were “best guesses,” Csinos said. “At the time, there was no scientific data to back up what they were saying, or selling.”Simple science?So Csinos took some simple blue dye and injected it through some drip tape under plastic on a raised bed at the UGA Tifton, Ga., campus. He then sliced down through the bed in various places. The blue designs in the sliced pieces of the bed showed exactly where the material was being deposited.”Now we can say with much more certainty how effective the drip tape is in delivering materials to the bed under the plastic,” Csinos said.Sandy soils pose a problem to Georgia and Florida, said Johan Desaeger, a postdoctoral scientist working with Csinos. Fluids tend to drop straight through them. Georgia’s soil can be as much as 88 percent sand. Florida’s can be 98 percent sand.Most raised vegetable beds are about 32 inches wide. To control vegetables’ top two enemies, nut sedge and nematodes, the entire bed needs to be fumigated. Nematodes are microscopic worms that feed on plant roots. Nut sedge is a weed.Initial studies in sandy soils showed that in many cases the drip tape wasn’t delivering enough material to spread adequately over the entire bed.”And when you don’t treat the entire bed, those pathogens outside the range of the drip tape survive and just come straight back to that area once the material has leached through,” Csinos said.Science doesn’t have to be complicated. It just has to be effective. Csinos, Desaeger and other UGA researchers have put many different drip tapes through the blue-dye test. And many more scientists and farmers have used this method in Georgia, Florida and South Carolina.Pesticide manufacturers now use results from this simple scientific method to write better directions for drip tape usage on their labels.last_img read more

Powered by Firework You know him as the swashbuckler on the 22 yards, raining boundaries and overboundaries around the stadium. The fierce nightmare of the opposition bowlers. Mahendra Singh Dhoni is still on his ongoing hiatus from international cricket, but the former Team India captain is still a sweet, blushing husband for Sakshi Dhoni, as she recent showed in a video about her ‘Sweetie of the day’!Advertisement Image Courtesy: Instagram(@sakshisingh_r)Sakshi is never shy from showing her family time on social media, and the supporters are always happy to see the bond between the couple. A couple of days ago she uploaded a two videos on her official Instagram, where she was seen playfully teasing MS Dhoni at the lobby of Taj Palace, a luxury hotel in New Delhi.Sahski captioned the clips with:“#sweetieoftheday 🤣🤣🤣🤣🤗 a lil bit of embarrassment but worth watching him blush ❤️ #thatsmile stay tuned for more !” Check out the humorous yet heartening clips below-Advertisement In the first clip, Dhoni is seel handing over his luggage to a hotel staff, as Sakshi calls him “Hi sweetie! Atleast look at me, atleast look at me, you’re not looking at me, why is my sweetie not looking at me?” as her husband is seen walking to the reception desk.As Dhoni avoids to give out any reaction and heads to the reception desk for some paperwork, mrs Dhoni is then seen walking to him as she calls Dhoni “Sweetie of the day” and “Cutie of the day” and asks the staff “He’s so cute, no?” who nods with a smile.In the second video, Dhoni is wearing an embarrassing smile on his face as he walks to the group of people as Sakshi continues to poke him with “How cute are you looking! Are you blushing?” as a shy and reddened Mahi finally opens up with a humorous response: “Can you do something to throw her out?”While the fans enjoy the usual rib tickling interaction between their favourite couple, speculations are still around about the 38 year old’s possibility of returning to cricket. With even the New Zealand series on its way, its likely to be the 2020 IPL season for Dhoni to make a comeback.Also read-Ravi Shastri hints strong IPL showing only way back for MS Dhoni; suggests ODI career could be overSakshi Dhoni weighs in on the bromance between Hardik Pandya and MS!

More Body Wonders

first_imgHere are more facts you probably didn’t learn in anatomy or physiology class.Neurons in the human eye are organized for error correction (Science Daily): “Seeing is believing,” but only insofar as it is accurate. This article discusses “Cells that send visual signals to the brain act collectively to suppress noise and improve accuracy.”Understanding X-chromosome silencing in humans (Science Daily): If females didn’t silence one of their X-chromosomes, they would have an imbalance of gene expression. “X-chromosome silencing is essential for proper development,” this article begins. Researchers add another protein to Xist involved in this operation. It’s called Xact. Interestingly, it appears in humans but not in mice.Super-you: Your body is a nation of trillions (New Scientist): It’s enough to give you the creepy-crawlies all night, just looking at the photo of an alien-like dust mite, then hearing that thousands of these eight-legged arthropods live on your face and skin. Indeed, Daniel Cossins writes, “Legions of creatures inhabit the cracks, contours and crevices of your body — and they all contribute to who you are.” You can take some comfort that it’s not just your problem. According to one Stanford biologist, “Each of us is really a complex consortium of different organisms, one of which is human.” Now back to sleep.Your left hand knows what your right hand is doing (Science Daily): Experiments at Tel Aviv University showed that when “people practiced finger movements with their right hand while watching their left hand on 3D virtual reality headsets, they could use their left hand more efficiently after the exercise.” The opening of the article says that “the saying” goes, “your left hand doesn’t know what your right hand is doing.” If that was an off-hand reference to Jesus, the actual quote from the Sermon on the Mount does not make such a claim. He said, “when you give to the poor, do not let your left hand know what your right hand is doing, so that your giving will be in secret” – implying that both hands are in communication. The metaphor was not intended as a statement of science, but as a figure of speech to make a point about almsgiving.Why we walk on our heels instead of our toes (Science Daily): A barefoot runner at the University of Arizona wondered why humans land heel-first when walking instead of ball-first. His analysis showed that “Walking heel-to-toe gives humans the mechanical advantage of longer ‘virtual limbs’.” James Webber explains:“The extra ‘virtual limb’ length is longer than if we had just had them stand on their toes, so it seems humans have found a novel way of increasing our limb length and becoming more efficient walkers than just standing on our toes,” Webber said. “It still all comes down to limb length, but there’s more to it than how far our hip is from the ground. Our feet play an important role, and that’s often something that’s been overlooked.“Webber makes up a story about how humans evolved this heel-first habit based simply on the observation that barefoot runners tend to land on the middle or balls of their feet. But he acknowledges that the Laetoli footprints show the pattern of heel-first walking began early.Laetoli Footprint NewsSpeaking of the Laetoli footprints, a new trackway has been found. Reported in eLife, it shows a modern gait with basically modern human feet, according to New Scientist. The problem is there should not have been any modern humans around 3.66 million years ago, when evolutionists believe these prints were made in Tanzania. But instead of focusing on that problem, the news reports latched onto the scientists’ supposition, based on the print sizes, that a fairly large male (5’5″, large for a presumed Australopithecus) was accompanied by several smaller females. That’s all that popular news reporters needed to go ape:“Ancient human ancestor was one tall dude, his footprints say” (Phys.org)“Oldest early human footprints suggest males had several ‘wives’” (Collin Barras in New Scientist)‘Lucy’ Species May Have Been Polygynous (Charles Q. Choi in Live Science)From prints to polygamy; that’s one giant leap for mankind. One can only wonder what such reporters would concoct from footprints left by a teenage boy leading his younger sisters to the beach.For all Choi or Barras know, the prints were made by children walking to Sunday School. That’s the danger of letting Darwinians into the science business. Their speculation knows no bounds.Speculation drops the more you focus on details. Let these evolution-drunk reporters tell us about evolving a foot by mutation and natural selection. Let them tell us the specific accidents that yielded an efficient center of gravity below ground as they walk. Let them tell us what mistakes led cells to cooperate to improve accuracy of vision. Let them explain how two different proteins cooperated to silence an extra X-chromosome, or how a blind natural process figured out it needed to be done in the first place.The devil is not in the details; that’s where the angel is. The devil lurks in the blurry figures the imagination conjures up in Darwin’s crystal ball when the lights are turned low.(Visited 54 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

CBI closure report ‘bad in law’: Punjab AG

first_imgTerming the Central Bureau of Investigation’s closure report in the 2015 Bargari sacrilege case “bad in law”, Punjab Advocate General Atul Nanda on Thursday said the national agency had no jurisdiction in the matter after the State government withdrew the cases from it last year. “The CBI lost all authority and jurisdiction to continue with any investigation in the cases, much less to file a closure report, after the State government issued a formal notification to withdraw the cases from the agency in September 2018,” said Mr. Nanda. He said that instead of filing the closure report, the correct legal course for the CBI would have been to inform the court that it was no longer charged with the investigation. The CBI had on July 4 filed a closure report in the three Bargari sacrilege cases of 2015 in the special CBI court in Mohali. Mr. Nanda also expressed surprise at the CBI’s stand that the State of Punjab was a stranger to the events, and thus not entitled to a copy of the closure report. “This stand was absurd, considering that the agency itself had, in its closure report, cited the ‘reports’ and ‘inputs’ of the Punjab police,” he added. ‘Dubious role’Meanwhile, Punjab Ekta Party president Sukhpal Singh Khaira accused the Chief Minister of playing a “dubious role” in the cases of sacrilege and asking the CBI to reopen the cases . “The Chief Minister failed to implement the resolution passed by the Vidhan Sabha to take back the cases from the CBI. On one hand, he advocated that the cases be probed by the SIT of Punjab police, while on the other he is asking the CBI to reopen the cases. This raises serious questions about his intentions,” said Mr. Khaira.last_img read more

Betrayed Canadians could launch unprecedented protests over pipeline activist

first_imgVANCOUVER, B.C. – Outrage over the federal government’s announcement about buying the Trans Mountain pipeline to ensure it gets built could fuel unprecedented protests, says a prominent environmentalist who was at the forefront of British Columbia’s so-called War in the Woods in the 1990s.Tzeporah Berman said the fight against the pipeline expansion is even bigger than those over logging in Clayoquot Sound.Canadians are angry the government is shelling out $4.5 billion to purchase the Trans Mountain pipeline rather than investing in clean energy after Prime Minister Justin Trudeau’s climate-change promises during the 2015 election and his later commitment to the Paris climate accord, she said. “The protesters and the opposition, and the civil disobedience is probably going to increase,” Khelsilem said.“Our mandate from our people is to continue to defend our rights as a people and to protect our territory, not just for us but for future generations. We’re going to continue to stand with our allies that support our Indigenous rights and change the story of Canada, that Canada is no longer a country that disregards Indigenous rights.”(THE CANADIAN PRESS) “My experience is that people are motivated by betrayal, they’re motivated by a lack of fairness, they’re motivated by a sense of shared common purpose and outrage. In this case we have all of that,” said Berman, who was cleared of aiding and abetting protesters at the Clayoquot blockade and is now an adjunct professor of environmental studies at York University in Toronto.Berman said the Liberal government “made a very big mistake” by backing Kinder Morgan’s project and alienating voters to create “a perfect storm” that would prompt people to take action.“I think a lot of us who knocked on doors for the Trudeau government really believed them when they said they were going to bring evidence-based analysis and science and democratic process back to pipeline reviews.”Berman is a director of Stand.earth, one of the groups that organized an anti-pipeline protest in Vancouver on Tuesday after Finance Minister Bill Morneau announced the government’s plans for the pipeline between Edmonton and Burnaby, B.C. Another protest is planned in Victoria on Thursday.“My expectation is that the outrage is going to grow and we’re not just going it see it here in British Columbia but we’re going to see it nationally and internationally,” she said, adding social media makes it possible for activists to connect in ways that didn’t exist at the height of anti-logging protests in 1993.Chopper 9 hovered over a rally was organized by First Nations and environmentalists opposed to the Kinder Morgan project.

It was a remote location that took most people five to seven hours to get through. This is a pipeline project that runs through urban centres,” she said of Trans Mountain.Khelsilem, a Squamish Nation council member who goes by his first name, said the federal government’s decision to pursue completion of the pipeline expansion threatens Indigenous communities if there was a spill of bitumen from increased tanker traffic in B.C. waters.“Trudeau had promised during the election that he would create a new environmental process that would protect Indigenous rights and that the Kinder Morgan project would be included and sent back to be done through the new process, and on both those counts he’s failed completely,” he said.Along with multiple legal challenges involving the pipeline, the Squamish Nation and five other First Nations are involved in a Federal Court of Appeal case that targets Ottawa’s approval of the project.last_img read more
