Press Association And after helping his side to a 1-0 victory in the game at Old Trafford, the 25-year-old Holland international told MUTV: “I’ve said many times before that I just want to play. “If you see what everyone can add to the team, then it’s a real battle for places and everyone had to fight for a position. “I got a chance on this occasion and I tried my best. Of course, people always say I don’t have the height or the power but I think I’m clever enough and smart enough. “I think we did well at the back, together with Chris (Smalling), Luke (Shaw) and Matteo (Darmian), and we got a clean sheet so I was happy.” Manchester United’s Daley Blind has hit back at those questioning the decision to play him at centre-back, insisting he is “clever enough and smart enough” for the position. Blind, seen more regularly in midfield or at left-back in his first campaign with United last term, was used as a central defender in the Red Devils’ 2015-16 Barclays Premier League opener against Tottenham on Saturday. There has been plenty of debate about his suitability for the role.
There were many emotional moments at the Donegal Half Marathon on Sunday as Mary Larkin completed the race in honour of her late husband, Dessie.Mary crossed the finish line with a fantastic 2:15:52 time.And Dessie’s angel wings carried her around the course, she said. Dessie Larkin, the Chairman of the Donegal Half Marathon, sadly passed away five months ago. He was in the hearts and minds of many people on Sunday and his legacy was celebrated in many thoughtful ways.Speaking after the race, Mary Larkin expressed her pride and gratitude to the Donegal Half Marathon committee for their work and their fitting tribute to Dessie.Video via @donegalhalfmarathon“It’s an honour to be here representing Dessie today, and I know that he’ll be looking down very proud and very humble,” Mary said. “Dessie will always be a part of this event. He was here today. His angel wings took me over the line today and one of his favourite sayings was ‘It’s not the size of the dog in the fight, it’s the size of the fight in the dog’. That came definitely came true today.”Mary presented the Dessie Larkin Perpetual Shield to the Donegal Half Marathon winner Ciaran McMonagle of Letterkenny AC.‘Dessie’s angel wings took me over the line’ – Mary Larkin completes Donegal Half Marathon was last modified: August 19th, 2019 by Staff WriterShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:Dessie LarkinDonegal Half-Marathonmary larkin
Science April 29 had three articles on the ATP synthase rotary motors that inhabit all living cells.1,2,3 Using creative techniques of extreme microscopy and crystallography, research teams are beginning to get more focused images of the carousel-like rotating engines of both F-type and V-type motors. (V-type enzymes pump ions into the cell to regulate acidity; see 2/24/2003 entry. F-type ATP synthase enzymes produce ATP, the energy currency of the cell; see 09/18/2003 entry.) The rotors look like elegant circular rings of helical units arranged at angles to the axis. From the side, they look like “concave barrel with a pronounced waist in the middle, and an inner septum that is probably filled with and electrically sealed by membrane lipids in vivo.” Scientists are still trying to figure out how the ions get into the active-site pockets in the subunits of the ring, and how they create torque to make the carousel go round. It may result from harnessing Brownian motion in a ratcheting manner that only allows rotation in one direction. All the researchers seem surprised that the gear ratio is not an integer, but rather 10:3 in some species, and 11:3 or 14:3 in others; it may be necessary that these motors have a non-integer ratio between the bottom carousel and the top catalytic engine for torque generation and catalytic activity (see 08/10/2004 entry). They are also beginning to understand the nature of the camshaft attached to the carousel that induces ATP production in the top. Whatever their mechanism, these little engines, only 12 nanometers tall, are effective. The review by Junge and Nelson says these motors can generate an acidity of pH 2 in lemons and 250 millivolts of electricity in insect guts. We humans also run on electricity. The constant action of quadrillions of these tiny generators running day and night in our bodies keeps all our energy systems humming at about 116 watts (see 02/05/2003 story). In another molecular-motor story, Current Biology4 reported about how actin and myosin work during cell division to pinch the two daughter cells apart. David R. Burgess in a review5 states, “Myosin II is the motor for cytokinesis, an event at the end of cell division during which the animal cell uses a contractile ring to pinch itself in half. New and surprising research shows that myosin, either through light chain phosphorylation or through its ATPase activity, also plays an important role in both the assembly and disassembly of the actin contractile ring.”1Wolfgang Junge and Nathan Nelson, “Structural Biology: Nature’s Rotary Electromotors,” Science Vol 308, Issue 5722, 642-644 , 29 April 2005, [DOI: 10.1126/science.1112617].2Murata et al., “Structure of the Rotor of the V-Type Na+-ATPase from Enterococcus hirae,” Science, Vol 308, Issue 5722, 654-659, 29 April 2005, [DOI: 10.1126/science.1110064].3Meier et al., “Structure of the Rotor Ring of F-Type Na+-ATPase from Ilyobacter tartaricus,” Science, Vol 308, Issue 5722, 659-662 , 29 April 2005, [DOI: 10.1126/science.1111199].4E. D. Salmon, “Microtubules: A Ring for the Depolymerization Motor,” Current Biology, Volume 15, Issue 8, 26 April 2005, Pages R299-R302, doi:10.1016/j.cub.2005.04.005.5David R. Burgess, “Cytokinesis: New roles for myosin,” Current Biology, Volume 15, Issue 8, 26 April 2005, Pages R310-R311, doi:10.1016/j.cub.2005.04.008.None of these five papers mention evolution once, nor make any attempt to explain how the motors of life could have arisen by an unguided process of chance or natural law. Murata’s paper says “Eukaryotic V-ATPases contain 13 different polypeptides.” Since getting just one usable polypeptide (protein) is astronomically improbable (see online book), it is utterly out of the question to assume that the complete set of these specialized functional molecules could have arisen by chance. Even getting a few of them would be useless; all of them have to be in the same place, at the same time, in the same arrangement, together simultaneously for the system to work. ATP synthase is a classic example of an irreducibly complex system that defies evolutionary explanation. Since even the simplest organisms depend on these motors for life, and since Charlie’s magic wand of natural selection cannot be used at this stage (see online book), we have here a convincing case for intelligent design. Similarly, since the actin/myosin operation is essential for cell division (e.g., replication, an essential prerequisite for natural selection), evolutionists have only chance as an explanation for the origin of these exquisite molecular machines. To any thinking person, that would be absurd. The Kansas school board (see 04/29/2005 entry) should hold up the pictures of ATP synthase from these papers and challenge the Darwinists to explain how such complex systems at the beginning of life could ever have arisen by chance.(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0
Share Facebook Twitter Google + LinkedIn Pinterest I hear the neighbor’s combine running and the semi rolling past the house so it’s a good night to harvest late. Hopefully as everyone harvested their soybeans they were observing what weeds are out there. We did have an open canopy for an extended period into the year due to the cool, wet growing conditions. This often leads to an increased number of weeds. Our county educators have been observing soybean fields across the state this fall to see what is out there for our annual fall soybean weed survey. See table 1 for our results.Table 1. The table below show the number of fields observed in each region, the percent of fields without weeds and weeds observed ranked by appearance.Region of OhioNumber of fields observed% of fields without weedsAppearance by weed; ranked in orderNortheast29626Marestail; grasses; Common lambsquarters; Volunteer corn; and pigweedsEast central7135Marestail; Giant ragweed; Common ragweed; and Redroot pigweedCentral20645Giant ragweed; MarestailNorthwest75546Marestail; Giant ragweed; Common ragweed; grasses; pigweedsWest central71622Giant ragweed; Marestail; Tall waterhemp; Volunteer corn; grassesSouthwest27033Marestail; Giant ragweed; Volunteer corn; common ragweed; pigweeds We do have a number of fields across the state that are weed free – a rough estimate from these number is about one third. So that means that we can manage our weed problems in soybeans, but it takes paying attention and being a good manager.No area is without some weed resistant to our major herbicide program – Roundup Ready technology. We have seen for a number of years now that Marestail is a major concern almost everywhere in the state. Few growers today can get away with ignoring this weed. Giant ragweed in some areas is now the dominant weed in soybean fields, and volunteer corn still is a problem – even though there are easy solutions for control of this lingering glyphosate tolerant volunteer. The pigweeds also appear in the surveys almost everywhere in the state – with a big appearance in west central Ohio. We must manage the pigweeds in general, and Waterhemp in particular much better than we do now.So who conducts the Fall Soybean Weed Survey by driving 80 miles on the road in each county? In Table 2, is a listing of the counties in the survey, the Extension educator, the number of fields and the acres they checked on.Table 2.

You can see in the list we had a significant number of counties and fields surveyed by our county Extension folks. Enough that we have a good idea of what is happening in each region of the state. They will report on local results by weed as we have our winter programs. What works?As I toured Ohio soybean growing areas over the summer, I checked with growers on what worked well for them. They reported the efforts they have gone to that reduced their weed problems in soybeans. Many found good yielding Liberty varieties and are happy they went all LibertyLink. And many of the OSU weed survey folks noted RRXtend signs on fields that had no weeds. This is the list that works — and sounds an awful lot like the recommendations of Mark Loux our Ohio State University Weeds Specialist.Apply a fall burndown that includes 2,4-D.. plus dicamba, plus glyphosate, or whatever – just don’t spend the money now on a residual. Especially for Marestail control.Increase use of metribuzin. Always a residual in the spring, even on worked ground.A switch to LibertyLink varieties, and due diligence on these other suggestions.Use of full rate of pre-emergent herbicide at planting in the spring. Even on worked ground.I add number 5 for 2018. Consider dicamba resistant soybean varieties.But a couple of items have come up on this option – the formulations labeled for soybeans are now restricted use herbicides. Because we had some movement of this herbicide.This means you need to have a pesticide applicators license, and take continuing education classes on managing drift, volatility and the environment.And your likely target weeds – Marestail and Giant ragweed have already shown a great genetic capacity for evading control.To learn more about managing weeds in Ohio. Attend your local county Ohio State University plant health recertification program – it was the Pesticide Recertification program but now includes fertilizer as part of the updates so I am calling it plant health recertification. Also recertification is now a four-hour program, up from three hours we had in the past.
Ace Indian shuttler Saina Nehwal stands just a win away from clinching her second title of the year after she stunned world number two and top seed Chinese Shixian Wang in a gruelling three-game semifinal contest of the USD 750,000 Star Australian Super Series in Sydney on Tuesday.Saina NehwalSixth-seeded Saina prevailed 21-19 16-21 21-15 in a marathon match, which lasted an hour and 16 minutes.”Beat world number 2 wang shixian in a tough 3 game match. Through to the final of the Australian Open super series!” tweeted the Indian after recording her fifth overall win against the Chinese nemesis, which took their head-to-head record to 5-3.Saina, who had ended up on the losing side in their previous two encounters — the most recent being the All England Championships, showed tremendous grit to outsmart the top-seeded Wang.As expected, it was evenly-contested battle between the two players, who are pretty familiar with each others tactics.In the opening game, it went neck and neck till 19-19 before Saina broke away to seal the issue in her favour.Not the one to give up easily, Wang roared back in the second game. The two players were even till the 16th point but Wang broke off from that point to draw level with Saina.However, Saina proved in the final battle of attrition and won the deciding third game rather comprehensively to enter the final.Saina had earlier this year won the India Open Grand Prix Gold in Delhi.
