Linkedin NewsHealthLifestyleHigh blood pressure affects one in four Irish adultsBy Liam Togher – May 30, 2013 1049 Walk in Covid testing available in Limerick from Saturday 10th April Twitter Facebook Hospital bosses deny claims of manipulating trolley figures WhatsApp ONE quarter of the adult population in Ireland is affected by hypertension, the medical term for high blood pressure.That’s according to Dr Liam Glynn, who was speaking during the Irish Heart Foundation’s (IHF) recent campaign for World Hypertension Day which included free blood pressure checks across the country, with the busiest stop being the Crescent Shopping Centre in Dooradoyle, where more than 120 people availed of the facility.Sign up for the weekly Limerick Post newsletter Sign Up Dr Glynn explained that the condition, despite affecting a quarter of the adult population, can be very difficult to diagnose and that adequate treatment is essential.“It is symptomless so we won’t know if people have it and it is very dangerous because it is a significant cause of heart attacks and strokes, which we are trying to prevent due to their implications.”Dr Glynn stated that only one in three adults with hypertension are diagnosed with the condition, and that only 33 per cent of those diagnosed are treated to an adequate level.He stressed the importance of going for a blood pressure check, as hypertension is difficult to spot but very preventable.“The best way to spot hypertension is to get your blood pressure checked. That’s the big message we’re trying to get across that no matter how stressed, fit or overweight a person is, they could have high blood pressure.As blood pressure increases with age, Dr Glynn recommends that any person over the age of 50 should get a blood pressure check every six months, and the same for any person who has been diagnosed with hypertension.He added that lifestyle changes such as regular exercise, weight loss and a low fat diet can help to ease people’s blood pressure.“I recommend exercising for 20 minutes a day, five days a week and weight loss also helps as there is a direct relationship between weight and high blood pressure. Reduce your salt intake and stick to a low fat diet, and if you are diagnosed, it’s important that you are on the right treatment and that you take your medication every day.”
Many marine predators migrate between breeding and non-breeding areas to target resources that are seasonal but spatio-temporally predictable, and so are vulnerable to climate-induced changes in prey phenology and abundance. In the Southern Ocean, small petrels are major consumers, but perturbations in the ecosystem through ocean warming are altering food-web structure and have been linked to poleward shifts in the distribution of their cold-water zooplankton prey. In this study, we focused on 2 small congeneric petrels: the broad-billed prion Pachyptila vittata and the Antarctic prion P. desolata. Both are planktivorous, but the broad-billed prion specialises in feeding on large copepods. We investigated historical trends in non-breeding distribution by analysing feather stable isotope ratios from a time-series dating back to 1926, and examined contemporary non-breeding distributions of broad-billed prions tracked using miniaturised geolocation-immersion loggers. After controlling temporally for the Suess effect, we found that the δ13C signatures of Antarctic prions, but not broad-billed prions, declined during the study period. This suggests a southward shift in Antarctic prion non-breeding distribution over the last century. Both species exhibited significant declines in δ15N during the same period, indicative of long-term decreases in marine productivity in their moulting areas, or changes in the trophic structure of prey communities. Tracked broad-billed prions migrated ca. 1000 km to an area east of the breeding colony where the Louisville seamount chain bisects the subtropical front. Topographically driven upwellings are stable and predictable features and may be crucial in aggregating plankton. Targeting seamounts could therefore mitigate the impact of climate-induced prey shifts by providing refugia for the broad-billed prion.
John E. Murdoch, one of the world’s top scholars of ancient and medieval science, died Thursday (Sept. 16) at age 83. He had been a member of the Harvard faculty since 1963, and professor of the history of science since 1967. He also taught at Harvard Extension School for six decades, and was a member of the School’s administrative board for more than 30 years.Murdoch was a renowned scholar of ancient Greek and medieval Latin science and philosophy, with a particular interest in the concepts of infinity and continuity throughout early science. He was the author of “Album of Science: Antiquity and the Middle Ages” (1984) and co-editor of “The Cultural Context of Medieval Learning” (1973). He also penned more than 60 scholarly essays on ancient and medieval science.Last year, Murdoch received his field’s highest honor when he was awarded the Sarton Medal by the History of Science Society, honoring lifetime scholarly achievement.“John took a hard-headed approach to the study of the hard sciences in the Middle Ages, always looking closely at what the texts said,” said longtime colleague Everett I. Mendelsohn, professor of the history of science emeritus at Harvard. “He took things seriously and took nothing for granted.”“John was also known for his very close work with his graduate students,” Mendelsohn added. “He pushed them hard, but was with them all the time.”A native of Milwaukee, Murdoch received his Ph.D. at the University of Wisconsin in philosophy, with a minor field in the history of science, in 1957. He taught at Harvard from 1957 to 1960 and, after teaching three years at Princeton University, returned as associate professor of the history of science in 1963. He served as chair of Harvard’s Department of the History of Science from 1966 to 1971 and 1974 to 1975.
The Spring Thaw is part of a three-event series that continues on March 21 at Fountainhead Regional Park and April 11 back at Willowsford. For more information regarding the event, contact [email protected] It’s been a long winter. Time to dust off the mountain bike, pump some air in the tires, and get ready to roll. The Rev# Spring Thaw Trail Series offers rides on moderatley challenging, purpose-built singletrack at Willowsford Conservancy lands near Ashburn, Va. Rides for all ages and abilities kick off at 12:30. Bikers pass through open fields and dense forests on the rolling course. Experts ride three loops (20.8 miles); weekend warriors can choose two loops (13.8 miles); newbies ride a single 6.8-mile loop.If you prefer two feet over two wheels, the Spring Thaw 10K and 5K trail runs will keep you on your toes. Runners can expect to be mud-splattered and wet-footed after the recent rains. The trail races start at 10 a.m.
Ferry operator Scandlines has signed an agreement with Norsepower to install the auxiliary wind propulsion system Rotor Sail Solution onboard the M/V Copenhagen, a hybrid passenger ferry.Operating between Rostock in Germany and Gedser in Denmark, the M/V Copenhagen combines diesel and battery power.With the addition of Norsepower’s technology, the ferry will further reduce its emissions.As informed, preparations for the retrofit will take place in November 2019 with the installation scheduled for Q2 2020. M/V Copenhagen is set to be retrofitted with one large-sized Norsepower Rotor Sail unit that is 30 meters in height and 5 meters in diameter.The Norsepower Rotor Sail Solution is a modernised version of the Flettner rotor – a spinning cylinder that uses the Magnus effect to harness wind power to thrust a ship. It is the first data-verified and commercially operational auxiliary wind propulsion technology for the global maritime industry.When wind conditions are favorable, it enables the electric propulsion thrusters and center propel to be throttled back, reducing emissions – while providing the power needed to maintain speed and voyage time. Because it generates supplementary thrust from wind, the solution is compatible with all other emissions saving technologies.The route between Gedser to the north and Rostock to the south is almost perpendicular to the prevailing wind from the west, giving Scandlines favorable conditions for using Rotor Sails on the ferry crossing.“By installing a Rotor Sail, we can reduce CO2 emissions on the Rostock-Gedser route by four to five per cent,” Søren Poulsgaard Jensen, Scandlines CEO, commented.German Nature and Biodiversity Conservation Union (NABU) welcomed Scandlines’ decision to further reduce CO2 emissions.“NABU welcomes Scandlines’ various efforts towards sustainable shipping. With rotors besides hybrid drives, the company sets new standards in terms of integrating different technical solutions to mitigate especially climate and air pollution emissions. To reach the Paris climate goals, more corporate responsibility by other shipping companies is needed,” Malte Siegert, Head of Environmental Policy at NABU, said.Commenting on the deal, Tuomas Riski, CEO of Norsepower said: “We are proud to be partnering with Scandlines as we work towards a modern era of auxiliary wind propulsion for the global maritime fleet, while supporting shipping’s transition to a low-carbon future.”Since 2013, Scandlines has invested more than EUR 300 million (about USD 335 million) in building and retrofitting ferries from conventional diesel-driven to hybrid ferries. With more than 43,000 departures on eight ferries, Scandlines transported 7.4 million passengers, 1.8 million cars and more than 700,000 freight units and 36,000 busses on the routes Puttgarden-Rødby and Rostock-Gedser in 2018.
