A team of scientists at Leeds University (UK) led by well-known design scientist Andy McIntosh has won an award for innovative design inspired by nature. “The team’s work has received the outstanding contribution to innovation and technology title at the Times Higher Education awards in London,” reported the BBC News. By studying and imitating the Bombardier Beetle (a long-standing creationist icon), McIntosh and team built an environmentally-friendly sprayer that uses heating and flash evaporation “to propel a variety of liquids up to 4m (13ft).” The team worked on this project for five years from concept to prototype. The device “may lead to improvements in the automotive and health industries…. it could inspire new types of nebulisers, needle-free injections, fire extinguishers and powerful fuel injection systems.” To what does McIntosh owe his award-winning success? “Nobody had studied the beetle from a physics and engineering perspective as we did, and we didn’t appreciate how much we would learn from it.”Compare this story with the one above it.

Share Facebook Twitter Google + LinkedIn Pinterest Hay growers always battle against the weather and through early July in 2015, the weather was clearly winning the battle. By July 5, only 67% of the first cutting alfalfa hay in Ohio was done and only 47% of the first cutting of other hay had been made, according the U.S. Department of Agriculture. Second cutting was also lagging far behind.Making hay has been tough going this year in northeast Ohio.“I have been hearing a lot of grumbling about this rainy weather pattern and comments about how difficult or impossible it is to get any hay put up,” said Rory Lewandowski Wayne County Extension educator, Agriculture and Natural Resources. “There has not been much dry hay that has been baled. If it was dry baled, it most likely had some rain on it. There was a brief window late last week through Monday of this week that allowed some hay to get baled without rain, but the quality was low because it was so mature. And that’s the other comment I am hearing — quality is low. This is going to have a ripple effect from now until next spring as this forage is fed.”Chopping has been the only way to get hay made in some cases.“For dairy producers, quite a bit of second cutting alfalfa was cut and harvested the second half of the week of June 22 to 26 and then again last part of last week. All of this is either wet wrapped baleage or ensiled as haylage in bunkers. First cutting on most of those acres was the week of May 18, so the timing for second cut meant lower quality with a lot of that alfalfa cut the second time at 50% to 75% bloom or greater in some cases,” Lewandowski said. “I was talking with a dairy producer yesterday and he mentioned that they got second cutting made, but only because they chop it and harvest as haylage. However, the quality is low and that is the feed source they have now. This will impact milk production and/or the cost to supplement that lower quality.”Decisions about moving forward will have to be carefully considered.“Part of the issue is also how much damage do you want to do to the field and those plants. You have to balance out field compaction, damage to plants, ruts, etc., which are longer-term issues with this shorter-term condition. We need one or two days of sun just to dry the fields out enough to get on them, and that is on the well-drained fields. There are other fields that need more time,” Lewandowski said. “Going forward I’m reluctant to say pray for sun and dry weather because I’m afraid that’s what we might get. With seven to 10 days of 90 degrees and sunshine, we’ll be looking for rain. So far this has definitely been a year that if you could wrap hay or chop hay for ensiling you are a little better off than those folks who need dried hay. But again, quality is going to come back to haunt us somewhat in terms of livestock performance and cost of possible needed supplementation later.”It was a similar story for hay in central Ohio and further south.“There’s a lot of first cutting hay yet to make in Fairfield County and also much of the state, some second cutting ready to make now also, and no weather to allow it to happen. Unless a person was in the lower half of the county that didn’t get as much rain the first week or so of June, wet wrapped it, or were just plain lucky, very little dry hay has been made to this point that appears to have much quality,” said Stan Smith, with Fairfield County Extension. “I haven’t seen any forage analysis yet, but once plants begin to mature their digestibility declines quickly. At this point in July, anything that’s not yet been made the first time is comparable to small tree twigs in most cases.“Locally we’re suggesting producers stay away from fields until they are dry enough to handle equipment without doing permanent damage to the field and the hay stand. At this point, the quality can’t decline too much more anyway, so waiting it out until soil conditions are acceptable costs little more. Even though we know the quality will be poor, producers need to make plans to have the forages tested and then decide what needs to be done to efficiently utilize it.”Smith suggests trying to improve the digestibility of low quality hay by finding a way to process it into smaller pieces.“Find a way to process it into smaller pieces as opposed to feeding it a long stem,” Smith said.With more rain in the forecast, it appears that hay struggles may continue in this soggy 2015 growing season.

This article is only available to GBA Prime Members Is solar electricity cheap or expensive? There are two parallel stories circulating these days. One version of the story — the older of the two — is that electricity from a photovoltaic (PV) array is more expensive than grid power, and that adding batteries makes PV even more expensive.The newer tale, oft-repeated on GBA, is that PV is cheap and getting cheaper, and that any utility that tries to limit PV installations is doomed to failure — because homeowners who are disgruntled by a PV-hostile utility will choose to install batteries, cutting the cord to the grid.Cutting the cord, a move called “grid defection,” is a key element of utility executives’ nightmares. The worry is that increasing instances of grid defection will cause utility revenues to drop, precipitating a “death spiral” for utilities.So, which version is closer to the truth? In some states, PV electricity is cheap Here’s my summary: right now, if available tax credits and rebates are taken into account, PV electricity is cheaper than grid power in many areas of the country with generous PV rebates — but only for grid-connected customers.If tax credits and rebates are ignored, PV electricity may still be cheaper than grid power for grid-connected customers — but only in areas of the country with high electricity rates or favorable net-metering agreements.In areas of the country where grid power is cheap, rebates are stingy, or utilities don’t offer net metering, PV electricity probably isn’t yet cost-competitive.In almost every location in the U.S., the cost of electricity produced by a PV system with enough batteries to permit “grid defection” is significantly higher than the cost of grid power.

A leader raises standards.The leader raises the bar for everyone. She sees what is possible for an organization and for the individuals that make it up–even when they do not. She believes that her vision can be made real even when no one else yet believes.By raising the standard, a leader insists that her people do better. She insists that they perform at a higher level, often a level that they don’t believe possible. She inspires, pokes, prods, coaxes, demands, and insists that they raise the bar. She forces them to use one of the greatest of all human attributes–resourcefulness–to find new ways to do the things necessary to moving towards her vision.And she leads. She holds herself accountable for doing the toughest jobs, making the toughest decisions, and changing herself and the organization to become what it is capable of becoming.The people who follow this leader will describe them as the person who did the most to help them become what they became, to realize their potential. But they won’t say that this leader made it easy for them. They’ll say this leader stretched them, starting with their vision.A leader raises the bar.Leadership is not a job. It isn’t a title you find on an organization chart. There are some people with titles that indicate they are supposed to be leaders, but their behavior betrays the fact that they aren’t.The non-leader lowers the bar or leaves it where they find it. They accept the organization and the people that make it up right where they are, never imagining more, never demanding more. Their lack of vision, their unwillingness to raise the standard, and their unwillingness to demand more wastes the potential locked up in the people who make up the organization they lead.If you lead others, raise the standard. No matter your position or role, you always lead yourself; raise your standard. Essential Reading!

(Facebook photo dated June 24, 2013)By Jorge Barrera APTN National NewsSenator Patrick Brazeau had a romantic relationship with the female owner of the house where Gatineau police said they conducted an “intervention” early Tuesday morning, according to photos posted online.APTN National News contacted the woman who refused to provide details about what transpired, saying only that Brazeau did not hurt her. She asked the reporter calling if they knew Brazeau.The woman recently posted photos on her Facebook page of Brazeau. Several photos show the woman and Brazeau in various poses embracing. One of the photos, posted on Sept. 24, has the letters “xoxo” typed across the top. The first photo showing the pair was dated June 24.Local radio station 104.7 FM reported Tuesday that a woman told authorities that Brazeau was in a state of “psychological distress” in a Gatineau, Que., home.The report said police detained Brazeau for his own health. The report said he resisted their intervention, leading police to use pepper spray. The report also revealed the location of the incident.Gatineau police issued a statement Tuesday evening confirming an incident occurred at the reported address.The statement said no one was charged with any crime and no information would be released about the incident. Police described the incident as “a possible intervention.”“This type of information is confidential and we will not answer any questions,” said the statement.Brazeau’s office issued an emailed statement Wednesday saying Brazeau was not arrested during the incident.His assistant described the incident as “health-related” in the email.“Canadians reasonably expect some measure of privacy regarding their personal health-related information and we would humbly ask the media to respect that privacy,” said the statement.Gatineau sits across the Ottawa River from Canada’s capital city.Neighbours described a chaotic scene that unfolded in the early morning hours Tuesday.One neighbour said she was woken just before 4 a.m. by flashing police lights across the street.The neighbour said she saw about four police cars and an ambulance. She said one individual, who appeared to be male, was put into an ambulance, while another man was put into the back of the police car.Another neighbour said one of the police officers was washing out his eyes out with water as a result of pepper spray.The neighbour said police remained at the house for until at least 4 p.m. on Tuesday and they saw officers in white jump suits, “like in CSI,” entering the house.Neighbours said the house is owned by a woman who is originally from Maniwaki, Que., which is Brazeau’s home town.Neighbours said the woman was renting out a basement apartment and that she left with family during the day.One neighbour said they saw the woman walking with a bandaged knee during the day Tuesday.Another neighbour said they saw a man with tattoos moving out of the house during the day.No one answered the door at the house Tuesday evening.Brazeau has a court date next Wednesday stemming from charges of assault and sexual assault against another woman he was once living with at a different house in Gatineau which he was renting. Brazeau no longer lives at that address. The current residents say they have been living there since September.Brazeau was appointed by Prime Minister Stephen Harper to the Senate in 2008.
