An article in The Economist suggests that dark matter and dark energy may not be necessary to understand the structure of the universe. It refers to two recent papers that explain the cosmic background radiation and galaxy clusters with ordinary matter, without a need for either of the other two unknown quantities. Are dark matter and dark energy like the fudge factors called epicycles that Ptolemy used to keep his outdated cosmology working? The article allows that, at this point, either side of the controversy could be wrong, but “On the other hand, a universe that requires three completely different sorts of stuff to explain its essence does have a whiff of epicycles about it. … one cannot help but wonder whether Ptolemy might soon have some company in the annals of convoluted, discarded theories.”Dark energy is the big fad these days. Leading cosmologists are certain they have proved its existence in this era of “precision cosmology” (see 06/20/03). A model that doesn’t rely on 96% unknown entities would seem to have a built-in advantage. Let’s watch to see who eats crow a few years from now.(Visited 95 times, 1 visits today)FacebookTwitterPinterestSave分享0
We’re into those hot days of summer–really hot–with temperatures predicted in the mid- to upper-90s, even in Vermont, this week. In this column I’ll provide some simple tips for keeping (reasonably) cool in hot weather or, if you use air conditioning, operating that air conditioning equipment most efficiently.Keep the sun outShading windows is the easiest way to keep your house cool or keep your air conditioning bills down. Pulling down interior window blinds will help (the more reflective the outer surface of the blinds the better), but shading is even more effective if you can block the sunlight on the outside of your windows. In Europe, exterior roller blinds are often used, and these are beginning to catch on here, but they’re not yet widely available. I’ve improvised exterior shading on a wide patio door facing west by propping up a tarp on the outside of the door, and that makes a huge difference. Climbing vines on a trellis, nearby trees, large potted plants that can be rolled in front of doors or windows, and awnings can also help a lot. If there’s no way to block that sunlight on the outside of windows and patio doors, install and use interior blinds.Keep hot air outClosing windows on hot days seems counterintuitive to some (don’t we want open windows for breezes?), but it makes sense. I have a digital indoor-outdoor thermometer on the north side of our house, and I use that to gauge when to open and close windows. When it’s hotter outside than inside, I close the windows, and when it’s cooler outside than inside, I open them. That’s pretty simple–but it does require paying attention and opening and closing windows fairly often. In hot weather, I often open up the house at night and close it up during the day.Minimize interior heat loadsTry to avoid generating a lot of heat and humidity in your house in hot weather. Consider meals that don’t require much cooking. Turn off lights when not needed (and replace incandescent light bulbs with CFLs). Make sure televisions and stereo systems are turned of when not in use (putting them on power strips allows you to turn them totally off to eliminate the “phantom loads”). Only run your dishwasher when totally full, and operate it in the middle of the night if possible. Wash clothes in cold water and hang outside to dry rather than using the dryer.Use a fan to circulate air when you’re in a roomAll other things being equal, a breeze will keep you a lot cooler. If you’re normally comfortable at, say, 72 degrees, using a ceiling fan or oscillating desk fan may enable you to be just about as comfortable with an air temperature of 75 to 80 degrees–because the moving air evaporates moisture from your skin. Note that fans don’t actually cool the air (in fact, they increase air temperature slightly from the motor’s waste heat), so turn them off when you leave the room.Wear lighter clothingThis is common sense, but bears repeating. Shorts, and loose-fitting shirts, blouses, and dresses allow more air circulation next to your skin and will keep you cooler. At the office, convince your manager to relax the dress code during hot weather.Control your air conditioner wiselyTo save energy, raise the temperature setting on your air conditioner’s thermostat when you’re not home. Keep windows closed when using an air conditioner–not only to keep hot air out, but also to keep down indoor humidity.These strategies can help you save money and maintain greater comfort during hot weather. They can also be lifesaving for vulnerable people (the elderly or ill) in the event of a power outage–as can happen in very hot weather when electricity demand is the highest. In late June, rolling brownouts affected over 100,000 customers in Brooklyn, New York; a more extended blackout could be deadly if it were to occur during very hot weather. If you lose power and don’t have air conditioning, simple passive measures will be critically important.In addition to this Energy Solutions blog, Alex writes the weekly blog on BuildingGreen.com: “Alex’s Cool Product of the Week,” which profiles an interesting new green building product each week.

For many, the next idea is going to be better than the one that came before it. They believe the next evolution of the sales process is going to be more effective than the existing process, the next new methodology better than the last. The next digital offering is going to revolutionize sales like nothing seen before, turning the industry on its head, and changing sales forever. The next new research report is going to provide a greater depth of understanding of how you should sell and what your clients need from you.Looking for “next” is chasing, and chasing is how one avoids doing the work necessary for producing better results. Also, there is something you can easily recognize in those who chase: they rarely ever execute the fundamentals consistently enough to produce results, being too busy looking for something better, something easier, and something new.If you are going to chase, chase impeccable execution of the fundamentals.You Know What You Need to DoThe execution of opportunity creation requires a few different activities. It starts with targeting your dream clients, those prospective clients who will perceive your value proposition as strategic, worth changing providers to obtain, and worth paying more for the better results you produce. Creating an opportunity means capturing mindshare by nurturing those relationships and executing a persistent, professional pursuit plan. You create opportunities by prospecting and scheduling meetings with your dream clients and prospects.The time you spend trying to avoid, over-automate, or over-optimize these activities, the worse your execution.In addition to executing against the activities that create opportunities, you need to execute opportunity capture, i.e., winning those opportunities. In most cases, this means face-to-face, or video face to video face, or ear-to-ear conversations with your dream clients. The execution of those meetings require you to plan your sales call, have a theory about what creates enough value for your dream client to continue to engage in the sales conversation, and gaining the commitment to take the next step. It also requires that you know how to control the process and, in complex sales, how to manage the many and varied stakeholders who are going to weigh in on any decision to change.The execution of a sales process includes good discovery work, proper development of solutions, and excellent presentation and proposal skills. All of this work now requires you have the business acumen and the relationship to create a preference to work with you, your company, and your solution.Everything outside of these two major outcomes, opportunity creation, and opportunity capture, is commentary, even when it is vital to good sales hygiene.All of this is to remind you that the difference in your future result isn’t likely to found in anything “new,” unless what is new is your commitment to impeccable execution.

Investigation teams in Indonesia and Ethiopia are focusing on faulty sensors and a flight control system designed to push the nose down in the air. Boeing says it has completed the necessary update for review by the FAA. But as of now, the agency has not said when that will happen.”We at Boeing are sorry for the tragic loss of lives in both of these accidents and these lives lost will continue to weigh heavily on our hearts and on our minds for years to come,” said Dennis Muilenburg, Boeing CEO, in a statement. “The families and loved ones of those on board have our deepest sympathies, and we hope this initial outreach can help bring them comfort.” Boeing Tour a B-17 and other aircraft at the Palm Springs Air Museum Boeing’s 737 Max 8 is grounded after two crashes that killed 346 people. Boeing Boeing will spend $100 million in the coming years to aid the families affected by two 737 Max 8 plane crashes. The planes have been grounded since March following the crashes, which left 346 people dead. The company said the funds will address “family and community needs” and support “education, hardship and living expenses for impacted families, community programs and economic development in impacted communities.” Boeing will work with local governments and non-profit organizations to carry out the aid. The first 737 Max 8 crash occured Oct. 29, when Lion Air flight 610 crashed in the Java Sea 13 minutes after takeoff from Jakarta, Indonesia, killing 189 people. Then, on March 10, Ethiopian Airlines flight 302 departed Addis Ababa Bole International Airport bound for Nairobi, Kenya. Just after takeoff, the pilot radioed a distress call and was given immediate clearance to return and land. But before the crew could make it back, the aircraft crashed 40 miles from the airport at 8:44 a.m., six minutes after it left the runway. 0 Tech Industry null Tags
Fish farming using bamboo and net fencing continues unabated in a four-kilometer area of the Ichhamati river in Nawabganj, Dhaka. Local residents suffer. The photo was taken recently. Hasan RajaA local chairman has been fish farming on the Ichhamati river in Shikaripara union of Nawabganj in Dhaka, hampering the river’s natural flow.This has caused local residents a lot of suffering.Chairman of Shikaripara union Alimor Rahman Khan erected a bamboo fence around a four-kilometre area on the Ichhamati river about five years ago and started fish farming.As a result, residents cannot freely use the river for bathing, fishing, or travelling. The life of aquatic animals is also in danger and river traffic cannot move.Residents say they have complained to the district administration.Under the authority of mobile courts, the Bangladesh Inland Water Transport Authority (BIWTA) has had the fence removed a number of times, but the chairman and his associates put up a new fence and start fish farming again.The residents allege this fish cultivation has been going on for the last five years. Around 600 fishermen from seven villages used to fish in the river. Now the chairman’s henchmen do not allow them to fish. They also prevent villagers from bathing in the river. When, The chairman’s men snatch away stray ducks from the river that belong to local residents.There are also allegations of local residents being beaten up and residents on both banks of the river are leading troubled lives.There is a large bridge over the Ichhamati river in front of a bazar in Shikaripara union of Nawabganj. Under the bridge, bamboo and net fencing form clusters of fisheries. Such operations can be found in other sections of the river including Mahespur, Garibpur, and Hagradi bazar.During a recent visit, this correspondent, on Sunday, found a bamboo and net fence stretching some 300 metres wide on the river near the Kashiakhali dyke.Local residents say such fences are there at about eight different places on the river.Speaking to Prothom Alo, a number of fishermen, including Amar Haldar, a fisherman from Daudpur, and Maron Barmon from Ananda Nagar, said they were not allowed to fish in the river for five years. Earlier, fishing on the river was their livelihood.Ali Hossain, Shikaripara bazar trader says there was a time when they travelled by launch on the river. Now, not even a boat can move on it. Because of a dyke built at Dasher Kandi, where the river originates, sand builds up in the area.Speaking to Prothom Alo, Awami League president of Shikaripara union, Mozammel Hoque, said the chairman is grabbing the river and water bodies of the locality using a “pocket” committee.According to chairman Alimor Khan at his home, the river flow is falling due to an embankment at Kashiakhali and water dries out during the lean season. Following these circumstances, the Directorate of Fisheries launched a project in 2017 to cultivate fish by dredging seven kilometers of the river. He said a 104-member committee comprising of fishermen, freedom fighters and their beneficiaries, are running the project. Alimor, who heads the committee, said Tk 1M is invested in the fish farming enterprise and the profits are distributed to the aforementioned beneficiaries.Asked whether it is fair to cultivate fish by obstructing the river, Alimore said, “The directorate of fisheries is not concerned about the flow of the river. The organisation focuses on fish production in the country.”About the allegations of local residents, chairman Alimor Khan said, “We do not torture anybody. Out of jealousy, some people spread false propaganda’.When contacted about the project, Iqbal Azim, deputy director of fisheries, , in charge of Dhaka division, said a project of dredging rivers and ponds across the country to cultivate fish was indeed undertaken.by. He also said the local administration leased out the water bodies to various beneficiaries. The department of fisheries provides the scientific and technical support, said Iqbqal Azim, adding that they provided technical assistance for the fish farming project on the Ichhamati river.He said the local administration attends to matters like grabbing, , and any hardships of local people.Upazila Nirbahi Officer (UNO) of Nawabganj-Dohar, AKM Al Amin, said he would investigate the allegations and take action.Prothom Alo Nawabganj Corresondent cooperated to file this report. * This report, originally published in Prothom Alo print edition, has been rewritten in English by Rabiul Islam.

Share Gregory Bull/APFlu patient Donnie Cardenas, right, waits in an emergency room hallway with roommate Torrey Jewett at the Palomar Medical Center in Escondido, Calif., on Jan. 10.The United States appears to be in the midst of an unusually severe flu season, officials at the federal Centers for Disease Control and Prevention said Friday.The flu season started early, which is never a good sign, and the flu is already widespread throughout the country, the CDC’s latest report shows. Half of states are reporting especially intense flu activity.“We are currently in the midst of a very active flu season with much of the nation experiencing widespread and intense activity,” CDC Director Brenda Fitzgerald told reporters during a briefing.Based on the latest available data, the United States could be experiencing one of the most severe flu seasons in years, possibly similar to the severe 2014-2015 flu season, officials say.“Flu is everywhere in the U.S. right now. There’s lots of flu in lots of places,” says Dan Jernigan, director of CDC’s influenza division.CDCActivity levels are based on the percent of outpatient visits in a state due to influenza-like illness (ILI) and are compared with the average percent of ILI visits that occur during weeks with little or no influenza virus circulation.Officials cautioned, however, that the flu is very unpredictable. So there’s a chance the season could slow down quickly or end early, making it a more normal flu season.But the most recent data show that the proportion of people rushing to their doctors to get treated for the flu has already hit 5.8 percent, which is as high as that number gets during the peak of a really bad flu season, the CDC says.In addition, the rate at which Americans are being hospitalized for the flu almost doubled in the last week, to 22.7 for every 100,000 hospitalizations, according to the CDC.Those are two of the key ways the CDC monitors the severity of a flu season.So far, 20 children have died from the flu, compared with a total of 101 last season.During the 2014-2015 flu season, 40 million Americans got the flu, 19 million people went to the doctor to get treated for the flu, and 970,000 people were hospitalized.Officials, cautioned, however, that the hospitalization rate for the flu so far this year is slightly below the 2014-2015 rate.The main reason the flu appears to be so severe is that it’s a strain known as H3N2. That strain tends to make more people sick, and the people who get the flu tend to get sicker. It’s especially dangerous for children and the elderly.“When H3N2 is prominent, we tend to have a season with far more hospitalizations and deaths,” Fitzgerald says.To make matters worse, the vaccine may only be about 30 percent effective against that strain. That is better than the 10 percent effectiveness reported in Australia, which has its flu season before the United States does and often predicts what will happen in this country.Nevertheless, health officials are urging people to get vaccinated. Any protection is better than none. And the vaccine may end up being more effective, especially if other strains of the flu become more common. The vaccine is more effective against those other strains. The vaccine can also lessen the severity of illness in people who get sick.The flu season may be peaking in this country, but it could continue for many more weeks. So even though it takes two weeks for the vaccine to start protecting people after they get vaccinated, it’s still worthwhile to get vaccinated, they say.“While our flu vaccine is far from perfect, it is still the best defense we have,” Fitzgerald says.Officials are also encouraging doctors to treat some flu patients with antiviral drugs quickly, including children, the elderly, people who get severely ill and those suffering from other health problems. While there are spot shortages of antiviral drugs, the overall supply is plentiful.Copyright 2018 NPR. To see more, visit http://www.npr.org/.
