A membrane roofing system is a popular choice for a commercial roof; it is designed to reduce the possibility of pooling and to reduce the incidence of leaks which are often associated with other roofing systems. This type of roof is rapidly becoming the favorite type of commercial roof, replacing the old traditional roofs that were used in the past. Membranes roofs are used on flat roofs or roofs which are only slightly sloped. The roofing system is available in three types; thermo-set, thermoplastic and modified bitumen.

A thermo-set roof consists of rubber sheets which are laid on the roof surface, the rubber sheets overlap at the edges. The overlapped seams are heated which causes the rubber to melt, resulting in the series of sheets to become one large continuous membrane. The rubber that is used in manufacturing the sheets is designed to form a chemical bond when heated; the seal becomes as strong as the sheet.

A commercial roof using a thermoplastic membrane is quite similar to a thermo-set roofing system but the material is PVC rather than rubber. The sheets of PVC do not form a chemical bond but they do form a tight seal when heated but the seal is effective on keeping out water. A thermoplastic membrane roof is somewhat less expensive than a thermo-set roof but it will need a little more maintenance.

Of the three systems, modified bitumen is the least expensive and the most common. The bitumen comprises rubber compounds and certain modifiers which are added to normal asphalt roofing compound. The modified bitumen is heated so that when it installed on the roof it forms a tight seal. There are new variation’s of this material; the new material does not need heat for application, it is produced in sheets in the factory; the sheets are lapped and held in place by self-adhesive strips, the seams, which overlap form a watertight seal.

A classic membrane roof system is prone to leaks because of the way it is constructed; this is not the case when a membrane is used as the commercial roof. In the case of traditional membrane roofs the seams are not sealed tightly, this is not the case with modern membrane roofs. Another advantage is that there is no need to place a gravel overlay which is normally the case with an asphalt roof. Because membrane roofing sheets are fastened directly to the roof, there is no need for gravel to hold them in place.

A flat or low slope commercial roof is constructed using one of the three different membrane roofing systems. For complete details on membrane roofs you are invited to contact StormForce of Jacksonville.

Chicago requires blind students to take driver’s education

Monday, March 13, 2006

Mayra Ramirez, a 16 year old Chicago, USA student is blind. In order to graduate, she and dozens of other visually impaired students in Chicago schools are required to pass a written rules-of-the-road exam. “In other classes, you don’t really feel different because you can do the work other people do,” Ramirez said. “But in driver’s ed, it does give us the feeling we’re different. In a way, it brought me down, because it reminds me of something I can’t do.”

Michael Vaughn, a spokesman for Chicago schools said, “I can’t explain why up to this point no one has raised the issue and suggested a better way for visually impaired students to opt out of driver’s ed.”

Blind students are typically told that they must take the class to graduate; although, by law, any parent can request a change in a disabled student’s education plan. This law is rarely, if ever, disclosed to the students, according to the Chicago Tribune.

New Zealand dog saves five children; receives international attention

Saturday, May 5, 2007

A small, “nicely trained” Jack Russell Terrier gave his life to help save a group of five children from two aggressive pitbulls last Sunday in Manaia, Taranaki, New Zealand.

The dog named George is being described as a hero, gathering a huge amount of international media interest in the process.

The dog suffered massive injuries that the vet had never seen to that extent before, which resulted in 69-year-old Alan Gay, the dog’s owner, allowing George to be put down. He now regrets this decision.

The two pitbulls rushed at the group of children that George was following to the dairy, including a four-year-old. George then started barking loudly at the pair of dogs, and put himself between the dogs and the children. Mr Gay told Fox News, “If it wasn’t for George, those kids would have copped it.”

Despite having received offers of new dogs, Mr Gay has said that he will wait a while before getting another Jack Russell Terrier, as he is afraid it could happen again.

It is also believed that the two attacking dogs, which have been destroyed, were bred to be aggressive, including being fed the drug methamphetamine, commonly referred to as “P” in New Zealand.

Mr Gay has said that Manaia has had a problem with stray dogs before, but he never expected that George would become a victim.

One story ran in USA Today, which prompted over 120 comments, and one reader to personally call Alan Gay expressing their condolences.

Responding to the huge amount of media interest, Mr Gay said, “This really surprises me, and it’s marvellous. I never expected this … I’m surprised it got around the world as it did.” He says he has been getting a huge amount of phone calls from the media and the public. “The phone has been going since about half past seven this morning. Every time I hang up it rings again. It’s worn out; I might have to get a new one.”

Czech woman wins the first Sudoku world championship

Sunday, March 12, 2006

Jana Tylova, a 31-year-old Czech woman, came from behind to win the inaugural Sudoku world championships to become the top sudoku player in the world. Tylova works as an accountant for a construction company in the Czech city of Most, and she beat 85 players from 22 countries.

A graduate student from Harvard University, Thomas Snyder, who had been leading, came in second and Wei-Ha Huang, a 30-year-old Google software engineer in California, came third.

Tylova, the only woman in the top 18, finished only ninth after the first round before passing all the men to claim the championship. She is already being called “Queen Jana of Sudoku”.

“There is no difference between men and women, and I tried to prove that even in logic, men and women are on the same level”, said Tylova as people cheered loudly. Jana smiled shyly while accepting her trophy from Wayne Gould who came upon Sudoku in Japan and popularised the game worldwide.

Jana told reporters: “I find it very difficult to give advice at all, but I can advise people to practice every day and to follow websites where there are a lot of games available.” Tylova revealed that before competitions she played sudoku two hours per day. “It will probably be more now”, she said. She showjumps with her horse Impulse during the rest of her spare time.

Austria, Belgium, Britain, Czech Republic, Croatia, Denmark, France, Germany, Poland, Hungary, the Netherlands, India, Italy, Japan, Venezuela, Switzerland, the United States, the Philippines, Estonia, Slovakia and Turkey were the countries represented in the championship contest.

When you hear about General Positioning System (GPS) system, you should first consider the GPS receiver. It is the part of the device responsible of processing the signal sent by the satellite in the space to find out your actual location. The receiver is usually placed on the dashboard of your car or underneath it. It renders on a dedicated output device your screen your destination.

The entire GPS is a constellation of about 27 satellites rolling around the center of the Earth at a steady speed. Amongst these satellites, 24 of them are responsible of processing signals emitted by the receiver and the remaining satellites are used for storage purposes on case of an unplanned event. The GPS receiver is responsible of hooking up with satellites used for storage purposes and working out its position from that satellite by computing their distance. The mathematical tenet used for this purpose is named trilateration.

Trilateration can be achieved in two dimensions and also in three dimensions. The rationale of this mathematical principle is to work out a triangle where you are located at the center of it. As soon as the GPS receiver emits its position and makes a connection with other satellites, it immediately works out three nearest points and computes your position.

[youtube]http://www.youtube.com/watch?v=FdcJVuylmsM[/youtube]

Three types of GPS receivers can be noticed: those which can be installed in a car, lightweight and mobile GPS receivers and tracking GPS receivers. It is obvious that portable receivers are a huge boon for outdoor activities.

Finally, it is good to know that the actual process of GPS receivers is a little bit more intricate than what was described in previous sections. However, throughout this article, although the main objective was to give a broad overview how they work in theory the next paragraph will delve into advanced details about GPS computations.

From previous sections, we learnt that the GPS receiver computes its distance to the nearest available satellites in space by noticing the time spent by the emission of a given signal from the receiver to the satellite. There are another category of GPS receivers that you have not mentioned throughout this article. In order to overcome the lack of precision of the traditional GPS receiver, differential GPS receivers were born. Their rationale is to estimate the level of GPS errors at a stationary receiver station with a location that was already computed before. Since the Differential GPS hardware at the station is already aware of its own location, it can work out its receiver’s level of errors in a straightforward way. The station then broadcasts a radio signal to all Differential GPS-equipped receivers in the nearby area, providing signal correction information for that area. In general, accessing this correction information makes Differential GPS receivers much more correct and precise than traditional GPS receivers.

The most essential function of a GPS receiver is to pick up the transmissions of at least four available satellites and combine the information in those transmissions with information in an electronic almanac, all in order to figure out the receiver’s position on Earth.

City to sue owner of partially collapsed 19th century livery in Buffalo, New York

Tuesday, June 24, 2008

Buffalo, New York —Two weeks after a 19th century stable and livery on Jersey Street partially collapsed and caused 15 homes to be evacuated in Buffalo, New York, residents still do not have answers from the city despite a court order to work with them and come to an agreement on a way to save some or all of the building, Wikinews has learned. Despite the frustration from residents, the city is planning on suing the building’s owner. A rally was held at the stable’s site where residents are hoping to bring more awareness to the situation and gain more support to save the building.

On June 11, a significant portion of the stable’s right side wall collapsed into the yard of a resident’s home. Authorities, including the Buffalo Fire Department were called to the scene to evaluate the collapse and evacuate 15 homes of residents surrounding the stable as a precautionary measure. The following day, the city ordered an emergency demolition on the building, which was stopped by a restraining order residents with Save The Livery (www.savethelivery.com) won on June 14. Two weeks later, five homes are still evacuated and residents don’t know when they will be able to return.

On June 19, Judge Justice Christopher Burns of the New York State Supreme Court ordered a halt to the emergency demolition and ordered the city and residents to come to an agreement to save the building, or at least a significant portion of it. Despite a court date today, no agreement has yet been reached between the two parties.

“It is in the interest of the city to have a safe environment–but also important to maintain a sense of historical preservation,” stated Burns in his June 19th ruling. The court ruled that a limited demolition could take place and that the city was only allowed to remove material in immediate danger to residents and pedestrians, but stated that the demolition could only be performed with “hand tools.” The court also ordered that any rubble which had fallen into neighboring yards when the building collapsed, to be removed. Since then, most of not all the significantly damaged portions of the building or portions in immediate danger of falling have been demolished. The roof has also been removed to put less stress on the stable’s walls.

“Its been over three years since we have been having problems with part of the livery falling down. There was an implosion two weeks ago and suddenly the city wanted to have an emergency demolition,” said Catherine Herrick who lives on Summer Street immediately behind the stable and is the main plaintiff in the lawsuit against the city. Many homes on Summer are small cottages which were used as servants quarters when the stable was in operation, many of which were built in the 1820’s. At least seven homes on Summer border the stable’s back walls. Residents in those homes have significant gardens which have been planted against the building and growing for decades.

“Both parties are to continue to work together to see how we can meet everybody’s needs. This is the third time we have been in that courtroom, and that is what we were basically told to do,” added Herrick who said the rally was held today because this “is Buffalo’s history. Buffalo is a wonderful place to live because of its history and this is a historical, beautiful building and we need to keep those beautiful buildings.”

Herrick states that the city is working with residents, but also believes that its “slow moving” and they are allowing the owner to get away with neglect on the property.

“I believe right now that they are letting the owner get off. The owner was negligent for 20 years, and hasn’t done anything to it despite what he has claimed to say. Now that this is an emergency situation, the city has a lot to say about it,” added Herrick.

Currently the building is owned by Bob Freudenheim who has several building violations against him because its poor condition. He has received at least five violations in three months and residents who live near the building state that Freudenheim should be “100% responsible” for his actions.

Freudenheim gave the city permission to demolish the building on June 12 during an emergency Preservation Board meeting, because he would not be “rehabilitating the building anytime soon.” Freudenheim, along with his wife Nina, were part-owners of the Hotel Lenox at 140 North Street in Buffalo and were advocates to stop the Elmwood Village Hotel from being built on the Southeast corner of Forest and Elmwood Avenues. They also financially supported a lawsuit in an attempt to stop the hotel from being built. Though it is not known exactly how long Freudenheim has owned the stable, Wikinews has learned that he was the owner while fighting to stop the hotel from being built. Residents say that he has been the owner for at least 22 years. Attorneys for Freudenheim confirm that the city is starting proceedings against him for his violations beginning as early as Wednesday June 25. Freudenheim has not released a statement and could not be reached for comment.

Many residents want the building preserved and Herrick states that their engineer can have it stable in “four days” as opposed to the 14-30 days it would take to demolish the building and “at a lesser cost than what it costs to demolish it.”

It will cost the city nearly US$300,000 to demolish the building which is paid for with tax money collected from residents in the city. The Buffalo News reports that fees are approaching $700,000. Though reports say there is a potential buyer of the stable, Wikinews cannot independently confirm those reports.

Residents say the stable was designed by Richard A. Waite, a 19th century architect, and was first owned by a company called White Bros., used as a stable and housed at least 30 horses at any given time. It also stored “coaches, coupes, broughams, Victorias and everything in the line of light livery,” stated an article from the West Side Topics dated 1906. According to the article, The company first opened in 1881 on Thirteenth Street, now Normal Avenue, and later moved into the Jersey building in 1892. The Buffalo Fire Department believes the building was built around 1814, while the city property database states it was built in 1870. It is believed to be only one of three stables of this kind still standing in the country.

At about 1950, the stable was converted into an automobile body shop and gasoline station.A property record search showed that in 1950 at least four fuel storage tanks were installed on the property. Two are listed as 550 square feet while the other two are 2,000 square feet. All of the tanks are designated as a TK4, which New York State says is used for “below ground horizontal bulk fuel storage.” The cost of installing a tank of that nature according to the state, at that time, included the tank itself, “excavation and backfill,” but did not include “the piping, ballast, or hold-down slab orring.” It is not known if the tanks are still on the property, but residents are concerned the city was not taking the precautions to find out.

Wikinews has called the city along with the Mayor’s office several times, but both have yet to return our calls. There are conflicting reports as to the date of the next hearing. According to Herrick, the next hearing is July 1, 2008 though the Buffalo News states the next hearing is July 8. The News also states that Burns will make a final ruling on the stable at this time.

Largest mass extinction in 65 million years underway, scientists say

Largest mass extinction in 65 million years underway, scientists say
Posted by , No Comments

Wednesday, March 8, 2006

Environmental scientists say they have concrete evidence that the planet is undergoing the “largest mass extinction in 65 million years”. Leading environmental scientist Professor Norman Myers says the Earth is experiencing its “Sixth Extinction.”

Scientists forecast that up to five million species will be lost this century. “We are well into the opening phase of a mass extinction of species. There are about 10 million species on earth. If we carry on as we are, we could lose half of all those 10 million species,” Myers said.

If we do not do more, Myers says, the planet will continue to lose around 50 species per day compared to the natural extinction rate of one species every five years. He projected this rate in the late 1980s to much criticism, but the figure is now widely accepted by scientists. “The whole thing is taking place in what you might call a flickering of an evolutionary eye,” said Myers. “It’s hard to keep up with unless we damp down on some of the causes of the evolution.”

Oklahoma trooper on leave after altercation with ambulance personnel

Oklahoma trooper on leave after altercation with ambulance personnel
Posted by , No Comments

Tuesday, June 16, 2009

An Oklahoma police officer is on paid administrative leave, following an altercation with ambulance personnel while they were transporting a patient to the hospital. Trooper Daniel Martin, a member of the Oklahoma Highway Patrol (OHP), was caught on video by his police vehicle’s dashboard-camera in a physical struggle with paramedic Maurice White, Jr. after Martin pulled the ambulance over. Martin had previously passed the ambulance while en route to another call, but came back and pulled over the ambulance. The incident occurred on May 24, and footage from the police dash-cam was released following a tort claim filed by paramedic White.

It has also been suggested that the previous call had in-fact been to pick up his wife from a police station who was then present in the car during the incident between Martin and the ambulance.

Footage by the OHP released Friday shows the ambulance personnel repeatedly informing Trooper Martin that they have a patient in the back of the ambulance that they are in the midst of transporting to the hospital. Martin yells at the ambulance driver for making what he claims was an obscene gesture – the ambulance driver asserts he raised both hands signalling confusion at the police officer’s actions. Trooper Martin can be heard telling the ambulance driver “I’m going to give you a ticket for failure to yield, and when I go by you saying ‘What’s going on?’ you don’t need to give me no hand gestures now, I ain’t going to put up with that [expletive], do you understand me?”

The video from the police dash-cam is eight minutes long, and paramedic White can be seen twice being pushed up against his ambulance by Trooper Martin. In one instance, Martin shoves White up against the ambulance while gripping his neck tightly with his other hand. In a written statement, paramedic White described the hold placed on him by the Trooper, stating “he engaged my trachea in a claw-like grip digging his nail into my neck while partially shutting off my air supply.”

[Paramedic Maurice White, Jr.] never once became aggressive to that trooper.

The sister of the patient in the ambulance, Clara Harper, was following the ambulance and witnessed the incident. Harper later viewed the footage from the police dash-cam, and she stated to Tulsa World paramedic White “never once became aggressive to that trooper.” She asserted that “He did nothing wrong.” After the ambulance was allowed to continue transporting the patient to the hospital, Harper got into the ambulance to be with her sister. “She was scared, and I was trying to calm her down and telling her everything was going to be all right,” said Harper.

My biggest concern was for the patient. If there’s any nightmare from this, it’s because of what that mother, that patient, had to go through.

Paramedic White was interviewed by KOKI-TV, and recounted his thoughts as the incident was taking place. He stated his main concern was for his ambulance patient: “It was surrealistic because I’ve never had such an experience. My biggest concern was for the patient. If there’s any nightmare from this, it’s because of what that mother, that patient, had to go through.” White’s attorney told KOKI-TV that if White deemed the arrest to be unlawful, he had the right to resist it. White is a paramedic for Creek Nation Emergency Medical Services in Oklahoma. He told FOX News he was surprised at the actions of the police trooper. “He’s taken an oath, just as I have, to protect and serve. I could not believe that this was happening,” said White.

The Oklahoma Department of Public Safety decided to release the police dash-cam video publicly after amateur video of the incident was posted to the video-sharing website YouTube. Captain Chris West, spokesman for the OHP, explained why the video was not released earlier. “We’ve been well aware of the fact that this incident has drawn enormous attention, but made the decision to protect the integrity of the investigation, any and all relevant evidence, as well as the rights of the department employees,” said West. Prior to the release of the dash-cam video, a relative of the patient had posted video of the incident to YouTube. The son of the ambulance patient can be seen in a video stating to the camera “Highway patrolman pulled over my mom’s ambulance because he’s mad we didn’t pull over, and he tried to arrest … the EMT from taking my mother to the hospital.”

One man is there protecting a patient and one man is there abusing his authority and throwing his weight around.

Richard O’Carroll, the lawyer for paramedic White, said that Trooper Martin abused his authority as a police officer. “Everything on this needs to relate back to why are we here? One man is there protecting a patient and one man is there abusing his authority and throwing his weight around,” said O’Carroll. White’s attorney filed a tort claim on behalf of his client in order to get the video of the police vehicle’s dash-cam released. Trooper Martin’s lawyer says he did not realize a patient was in the ambulance at the time of the incident.

O’Carroll explained the decision of paramedic White not to use sirens while transporting his patient to the hospital: “There was a reason he wasn’t running sirens. There was a suggestion of chest pains and a heart condition and sirens aggravate these conditions by increasing the blood pressure.” However the attorney for Trooper Martin, Gary James, said that the ambulance was not exempt from regulations because it did not have its sirens on. “If they’re not running their sirens or lights, they don’t get afforded any emergency vehicle exemptions,” said James. The OHP chief is handling an internal review into the incident. As of June 1, Trooper Martin has been on paid administrative leave.
