Japanese researchers create smell sensor using genetically engineered frog eggs
Japanese researchers create smell sensor using genetically engineered frog eggs

Sunday, August 29, 2010

A University of Tokyo group of researchers, led by bioengineer Shoji Takeuchi, has made an electronic sensor capable of smelling gases. The sensor uses genetically engineered frog cells. Since previous sensors were not very accurate, the scientist decided to try a biological approach. The invention was revealed in a US scientific journal yesterday, and is supposed to be used to design better machines to detect polluting gases in the atmosphere.

Previous smell sensors were based on quartz rods, which vibrate when a substance binds to them. The gases are distinguished by their molar masses, which can be similar for molecules with different structure, thus relatively often triggering a false positive. Trying to find a more accurate solution, Takeuchi decided to follow an example from insect world. As he explained, “when you think about the mosquito, it is able to find people because of carbon dioxide from the human. So the mosquito has CO2 receptors. When we can (extract) DNA (from the mosquito) we can put this DNA into the frog eggs to detect CO2.”

Genes of several insects (the silk moth, diamondback moth and fruit fly), injected into African clawed frog Xenopus laevis eggs, allowed them to produce relatively inexpensive and useful sensors. The choice of the species was caused by their widely studied and well-understood protein expression mechanism.

The modified cells responded to three kinds of pheromones and one odourant, which have similar chemical properties. When a molecule of an odorous substance adhered to the receptor on the membrane protein, ion channels opened for a certain period of time, and a current was generated. Its magnitude was clearly different for all four tested substances, allowing to distinguish between them accurately.

The colleagues embedded the sensor into a mannequin, so that it could shake its head when a gas was detected. It was easier to observe. Pheromones and molecules with quite similar molecule structure produced clearly distinguishable reaction, with higher accuracy than other biological or human-made sensors. As the research group said, the detection sensitivity of the odor sensor is several tens of parts per billion (ppb), and it is as high as the sensitivity of an existing odor sensor that uses an oxide semiconductor. The distinctive feature of the new sensor is its capability to selectively detect some odorous substances, rather than its sensitivity. Very few false positives were possible due to the biological mechanism involved.

At normal temperature, the sensor lifetime is about 12 hours, which can be extended by putting it into a refrigerator before first use.

Shoji Takeuchi says has a great hope for research use in future, since the frog eggs are very practical for genetic engineering, and can be conveniently used to develop smell sensors for a wide range of gases. He said, “The X. laevis oocyte has high versatility for the development of chemical sensors for various odorants. We believe that a shared ability to smell might open a new relationship between man and robot. .. The research will have wide implications… If the sensor is embedded in a nursing robot, it will be able to identify certain mouth odors or body odors. Also, it can be used for detecting CO2, air pollution, water pollution and food. It’s very important for the environment.”

Twelve injured in Washington after ride at fair topples over

Sunday, April 19, 2009

At least twelve children have been injured after a swing ride at the Puyallup, Washington Spring Fair toppled over.

The ride is called a ‘LollySwing’, which is located in Kiddyland, where the riders sit in swings while the machine spins them around. It is owned by Funtastic Traveling Shows which has been a ride provider for the fair for over 50 years. The accident happened at around 6:30 p.m. (PDT).

Injuries are being described as mostly cuts and bruises, but one child was reported to have been in a neck brace and was taken to a local hospital. Five other children were also hospitalized.

According to one witness, “it just all of a sudden topped over.” The cause is under investigation. The ride has been at the fair for the past five years. Among the seven largest operators of fair rides in Washington, from 2001 to 2007 there were only seven reports of injuries related to mechanical failures.

Woman killed on amusement park ride in New York
Woman killed on amusement park ride in New York

Sunday, July 1, 2007

A young woman was killed Friday night after an accident occurred on a gyrating ride at the Playland amusement park in Rye, New York in the United States. The woman, Gabriela Garin, was a worker at the amusement park, and had worked there for the past seven years.

The accident occurred near the end of Garin’s shift; as she was loading riders onto the ride. The ride’s new operator, unaware of Garin’s presence, started the ride while Garin was still on it. The new operator then noticed Garin, and shut the ride down in 20 seconds, but Garin had already been ejected from the ride and killed, according to a park spokesperson.

The ride is an attraction that spins people around in two-seat cars, inside a darkened tent to flashing lights and music.

This incident is not the first in the ride’s history. In 2004, a seven-year-old from Connecticut managed to free herself from the ride’s restraining bars, and climb onto the front edge of her seat. She fell soon after the ride started. A safety precaution was put in place after this incident, however, the spokesperson acknowledged that it was not followed when Garin was killed.

The company which owns the ride shut it down, along with two other rides it owns at the park.

This is the fourth fatality in the park’s history. The park features more than 50 rides, a pool, and a beach. It attracts more than 1 million visitors annually.

Generally trucks with the load lifting capacity of more than 14,000 pounds, make use of a hook type forklift forks.

Pin Type forklift forks: These types of forklift forks are attached to the carriage of the forklifts with the help of a shaft or a pin and are therefore known as pin type forks. There is a small opening on the top of the fork through which a shaft slides in. It is through this pin that the fork is locked to the carriage of the forklifts. Generally the lift trucks that are expected to carry huge loads make use of pin type of forklift forks.

Forklift forks can be further classified on the basis of the blades of the forks

Forklift forks with the blunt end and tapered blades: These types of forks are very well suited for simple lifting as they can be very well inserted I to the pallets. Forklift forks with blunt or tapered ends are the ultimate option for handling merchandise which is likely to be punctured with the piercing ends of the forks. For instance, plastic bins and drums and so on,

Forklift forks with the stainless steel clad blades: These types of the forklift forks are very well suited for environments that need to be kept spark free. Commonly places where paints and chemicals are handled, tends to be explosive and are therefore required to be kept spark-free. Forklift forks with stainless-steel blades are also suitable for places where ultimate hygiene is required.

Forklift forks with ITA Class 2 and Class 3 Block blades: The lift trucks that make use of forks with these types of blades are more commonly used in lifting huge concrete blocks at one go. These forklift forks are used by people in the construction trade. It consists of a concave radius along with the longer tube that helps in the application on rough areas.

Forklifts with telescopic extending blades: Manutel G2 is the best option for telescopic extending blades. They belong to the pin type category as they fix in to the equipment with the help of a locking pin which can be comfortably removed. The extension lengths of these forks are within legal maximum length permitted. The lift trucks that make use of forks with these types of blades are perfect for indoor use.

California meat packing firm recalls 143M pounds of beef
California meat packing firm recalls 143M pounds of beef

Sunday, February 17, 2008

I am dismayed at the in-humane handling of cattle that has resulted in the violation of food safety regulations at the Hallmark/Westland Meat Packing Company.

In a press release today, California-based Hallmark/Westland Meat Packing Co. indicated that it has voluntarily recalled just over 143 million pounds (65 million kilograms) of raw and frozen beef products, which is considered to be the largest single recall of beef products in U.S. history. The move follows an investigation by the United States Department of Agriculture (USDA) into allegations of animal cruelty and mishandling of cattle destined for the human food chain.

The USDA’s Food Safety and Inspection Service (FSIS) had determined that beef products produced by the Chino, California company were unfit for human consumption as the cattle had not received “complete and proper inspection.”

The recall has been designated as Class II, which the USDA describes as “a health hazard situation where there is a remote probability of adverse health consequences from the use of the product.”

On Friday, Secretary of Agriculture Ed Schafer indicated that charges had been laid against employees of the plant alleged to have taken part in the mistreatment of cattle. “Today [Friday], the San Bernardino District Attorney filed felony animal cruelty charges against two employees who were terminated by Hallmark/Westland Meat Packing Company,” said Schafer. “It is regrettable that these animals were mistreated and I am encouraged and supportive of these actions by the San Bernardino District Attorney in response to this mistreatment.”

The USDA learned of the possible inhumane handling of non-ambulatory (disabled) cattle at the packing plant on January 30 and has since suspended activities at the plant. “We continue to conduct a thorough investigation into whether any violations of food safety or additional humane handling regulations have occurred,” said Secretary Schafer in a press release. “On February 8, our Office of the Inspector General took the lead on the investigation. At that time, USDA extended the administrative hold on Hallmark/Westland Meat Packing Company products for the National School Lunch Program, the Emergency Food Assistance Program and the Food Distribution Program on Indian Reservations while the investigation continues,” said Schafer.

The FSIS reported that Hallmark/Westland had not contacted the FSIS public health veterinarian, as required, when cattle became ill or disabled after undergoing ante-mortem (slaughter) inspection, putting the company out of compliance with FSIS regulations. “Because the cattle did not receive complete and proper inspection FSIS has determined them to be unfit for human food and the company is conducting a recall,” explained Secretary Schafer.

The cruelty charges stem from an undercover video that reportedly showed sick cattle being moved by crews using forklifts.

“Words cannot accurately express how shocked and horrified I was at the depictions contained on the video that was taken by an individual who worked at our facility from October 3 thru November 14, 2007,” said Steve Mendell, President, Westland Meat Co. and Hallmark Meat Packing. “We have taken swift action regarding the two employees identified on the video and have already implemented aggressive measures to ensure all employees follow our humane handling policies and procedures. We are also cooperating with the USDA investigators on the allegations of inhumane handling treatment which is a serious breech of our company’s policies and training.”

The USDA stressed that it is “extremely unlikely” that the cattle involved were at risk for Bovine spongiform encephalopathy (BSE) or mad-cow disease due to the employment of multiple safeguards. The USDA felt the recall was required, however, as the plant had allegedly violated USDA regulations.

The recall involves raw and frozen beef products produced on various dates from February 1, 2006 to February 2, 2008. For further information about the recall, consumers, media, and distributors are encouraged to contact Hallmark/Westland’s Plant Manager Stan Mendell or Food Safety Consultant Steve Sayer at (909) 590-3340 or the FSIS website, www.fsis.usda.gov.

Explicit Canadian workplace safety ads pulled from TV due to Christmas season
Explicit Canadian workplace safety ads pulled from TV due to Christmas season

Thursday, December 13, 2007

Controversial and explicit Canadian workplace safety ads have been pulled from television, and paper ads from some bus shelters for the Christmas season. However, the ads will return to air in January.

“It’s totally erroneous to suggest we’re pulling anything,” chairman of the Workplace Safety and Information Board of Ontario, Steve Mahoney said. “Our plan from Day 1 was to stop the ads around the middle of December when most of the advertising that’s in the media is focused on Christmas and purchasing gifts. We just didn’t want to be competing with all that stuff.”

In one of the TV ads a woman accidentally slips on grease on the floor and a large steaming pot falls onto her face, and she starts screaming to death. The ads end with the message “There really are no accidents”.

A paper ads shows a construction worker who is in a pool of blood with a forklift operation manual stuck in his chest. Another with a man who is slit by a “Danger” sign with his leg stuck in a machine. They show the messages: “Lack of training can kill” and the other “Ignoring safety procedures can kill”.

“The critics amount to about 25 per cent rating, and I’m delighted they’re upset about the ads because I wouldn’t want anyone to enjoy watching them.”

The videos have been viewed more than 70,000 times on the Board’s website and are gaining large amounts of views on YouTube.

The transit authorities of Hamilton and Mississauga will show modified advertisements. The transit authority of Guelph will show the ads in bus shelters, but the transit authority of Windsor will not because of the graphic nature.

“We’re not against workplace safety, but this is too graphic,” said Caroline Postma, chair of the Transit Windsor board.

Mississauga city councillour Carolyn Parrish said: “My son-in-law was telling me that they shouldn’t be on in prime time because when [my grandson] watches them he just about bursts into tear. Now he follows his mom around the kitchen to make sure she doesn’t spill grease. And he’s only four. There’s too much of a chance that … people are really badly affected by it, and can’t really do anything about it anyway.” She suggested the ads only be aired to workers with the jobs shown in the commercials.

Mahoney changed the earlier promise to air the ads only after 8:00pm to after 9:00pm at last nights meeting with Mississauga city council.

Mahoney said the commercials and paper ads are not “too graphic at all”. And they are “absolutely appropriate and they’re doing what they’re intended to do, they’re creating what I call a water cooler topic of conversation.”

Ninety-eight Canadian workers so far have been killed on the job this year.

Google starts prefetching top search results for Mozilla and Firefox browsers
Google starts prefetching top search results for Mozilla and Firefox browsers

Friday, April 1, 2005 Google engineer Reza Behforooz announced in a Google blog entry on March 30 that search engine Google has enabled “link prefetching” for some of their search results. The link prefetching has not been standardized, but it can enable faster page loading of Google search results in Mozilla and Firefox browsers that have the feature enabled.

When Google determines a user has a high likelihood of clicking on a search result, Google inserts a tag into the results they send out in response to a search. Some browsers can then preload that page, so in the event the user does select the page, it loads very quickly.

For example, a Google search for “wikipedia” today by Pingswept yielded an HTML page with this code included:

<link rel="prefetch" href="http://en.wikipedia.org/wiki/Main_Page">

While not a formal benchmark, in casual testing by Pingswept, Firefox 1.0.2 loaded the Wikipedia main page in about half the time when the page had been link prefetched, as opposed to when it had not been. The load times were approximately 1.5 seconds and 3 seconds respectively. Internet Explorer 6.0 loaded the same page in slightly less than 3 seconds.

Users who want to disable prefetching in Firefox can do the following:

  1. Type “about:config” in the address bar.
  2. Scroll down to the setting “network.prefetch-next”.
  3. Right-click on the value and click “Toggle”.

The Bright Side Of Todays Advancement Healthy Diet Recipe}

Submitted by: Steven Magill

There was a time when people really didnt take much notice of what they were eating. Especially in the 1800s when the west was just starting to be explored, when settlers began home steadying land, when a hard days work meant waking up at dawn, to plow the fields, herd cattle, or set up fences, men ate what they could eat and did not seem to gain weight. This is due to the fact that they had active lifestyles and they spent their days sweating it out and doing hard labor in order to survive and get by. Those days are gone and the modern mans work is not as tedious and laborious as those in the past.

We are more sedentary these days. Most of us toil seated in our own cubicle or office, staring at the computer or reading and analyzing data and information given to us. This is not necessary a bad thing as we have become such an efficient economy and people are really more productive in terms of producing goods and services. Advancements in technology have automated a lot of the processes that were once done manually. Take for example agriculture and farming. Machines have been invented to plow and cultivate the acres and acres of land so that what used to take 50 people to do is now being done by two or three persons. Surplus in agriculture has led to surplus in food supply as well. People know are eating more because there is more food and more choices. Groceries and supermarkets enable us to stock with as much food as we can possibly want. There is theoretically no limit with the amount of food we can purchase.

So we are a bit out of balance. Normally we eat heartily to sustain for the next day of hard toil and manual labor. This is not true anymore, as we dont work too much under the sun these days. Added to this, we have produced additives made to sustain the shelf life of food. As productive as we are, there is less and less time for other things like food preparation and the convenience of buying ready to eat food is more than tempting, it is downright practical. Eating out also has its drawbacks since servings have increased in size over the last two decades. With the value for money concept still en vogue, restaurants and fast foods cope with such by giving us large portions. To upsize things as some fast food chains push their products. These all affect the health of our nation and sad to say we have become a nation of obese people.

Still there is a bright side to this. Advancements in research on proper eating provide us with healthy diet recipes that can help us lose and maintain the weight loss as well. The healthy diet recipe may vary from program to program. There are different philosophies that all have creditability and legitimacy to their method in losing weight. The healthy diet recipe may come in the form of a recipe itself, strictly followed, or may come in ready to eat meals for those people on the go. This is one good outcome of our advancements through time. A healthy diet recipe is always available for you to utilize.
