Toothpaste fills cavities without drilling

Thursday, February 24, 2005

A paste containing synthetic tooth enamel can seal small cavities without drilling. Kazue Yamagishi and colleagues at the FAP Dental Institute in Tokyo say that the paste can repair small cavities in 15 minutes.

Currently, fillers don’t stick to such small cavities so dentists must drill bigger holes. Hydroxyapatite crystals, of which natural enamel is made, bond with teeth to repair tiny areas of damage.

Yamagishi and colleagues have tested their paste on a lower premolar tooth that showed early signs of decay. They found that the synthetic enamel merged with the natural enamel. The synthetic enamel also appears to make teeth stronger which will improve resistance to future decay. As with drilling, however, there is still the potential for pain: The paste is strongly acidic to encourage crystal growth and causes inflammation if it touches the gums.

The paste is reported in the journal Nature.

National Parties

In the lead-up to the 2008 Canadian federal elections much speculation was made about environmental issues and initiative, with various parties maneuvering to claim some portion of the green mantle. But it was the Liberal party which first brought a full-blown policy to the public.

In the months since the Green Shift initiative was brought forth, the political pundits and activists have both talked about this year as the first election where the environment would be a major issue on the minds of voters, and possibly a decisive one for the electorate.

It’s indeed true the environment ranks very high in minds of voters across the country, particularly among young voters. One national survey of Canadians between 18 and 25 finds the environment is the top issue. A poll of all voters found it to be the third most important single issue over all, behind the economy and health care, but the poll suggested that no one issue has really caught the attention of the electorate with many issues gaining similar attention.

The parties themselves seem indecisive, trying to claim a focus on environmental issues but rarely making specific proposals or promises, with the notable exception of the Liberals whose platform has been targeted by opponents and commentators as “wildly experimental” and “doesn’t go deep enough” by turns.

Examining the platforms of the New Democratic Party regarding air pollution and global warming as available on their website, one is struck by a lack of substance. Reference is made to C-377, the Climate Change Accountability Act, which the NDP calls “Layton’s Kyoto-Plus Bill”, which was passed in 2006. The party believes Canada can achieve its Kyoto requirements by 2012, though no mention is made of how a Layton government would do so.

In June of 2008 the Liberals tabled a plan, the Green Shift, which they claim would reduce Canada’s greenhouse gas emissions 20% under 1990 emissions – well below the 6% required by Canadian law when Canada ratified the Kyoto Accord – by 2020, which is rather after the 2008-2012 phase-in period required by that same law. The method of performing this reduction would be to shift the Canadian tax system, reducing income and revenue taxes by replacing them with taxes on greenhouse gas emissions. The plan generated considerable discussion and opposition, and the party has back-pedaled in some portions and added on in others, as well as announcing a couple of separate initiatives to soften the effects for farmers, homeowners, and fishermen among others.

A more diverse approach than solely a “Carbon Tax” is proposed in the Green Party’s platform, which presents an almost holistic approach of adherence to the Kyoto obligations, “Cap and trade” of carbon emissions, industry development with both green technology R&D and regulation as well as consumer subsidies, and their own version of a carbon tax. Alone of the parties they specifically mention the role of international diplomacy/trade as a part of their approach.

Such an approach appears to be anathema to the Conservatives, whose mantra since their election has been that Kyoto cannot be complied with without forcing an economic recession on the country, and used the Throne Speech of 2007 to reiterate that position. They have opposed cap-and-trade schemes in the past, but their platform for this election states their plan to reduce greenhouse gas emissions includes emissions caps for “four air pollutants commonly associated with smog and acid rain,” as well as “tough emission reduction targets”.

In contrast to the laundry-list of unconnected initiatives on the Conservative’s website, the clean platform pamphlet created by the Bloc Québécois makes a simple and apparently heartfelt statement on the environment:

La lutte aux changements climatiques est devenue un enjeu fondamental pour l’humanité et le Québec est déterminé à apporter sa contribution, à sa façon. À Ottawa, c’est le Bloc Québécois qui mène la lutte en faveur de l’application du protocole de Kyoto dans le respect des choix du Québec.
Tackling climate change has become a fundamental issue for all of humanity and Québec is determined to make its contribution, in its own way. In Ottawa, the Bloc Québécois, respecting Québec’s choices, is leading the fight to enforce the Kyoto Protocol.

Just how they plan to enforce the Kyoto obligations is not stated, though they do discuss a carbon market, and tax incentives for home heating upgrade and transportation.

There seems to be a wide if somewhat shallow interest in the electorate as to just what each party is offering on the environmental file. But with sketchy platforms regarding environmental issues, it’s no wonder some of the parties have turned to the subject of economics in recent days.

China overtakes Germany as world’s biggest exporter

Sunday, January 10, 2010

Chinese officials have said that their country’s exports surged last December to edge out Germany as the world’s biggest exporter.

The official Xinhua news agency reported today that figures from the General Administration for Customs showed that exports jumped 17.7% in December from a year earlier. Over the whole of 2009 total Chinese exports reached US$1.2 trillion, above Germany’s forecast $1.17 trillion.

Huang Guohua, a statistics official with the customs administration, said the December exports rebound was an important turning point for China’s export sector. He commented that the jump was an indication that exporters have emerged from their downslide.

“We can say that China’s export enterprises have completely emerged from their all-time low in exports,” he said.

However, although China overtook Germany in exports, China’s total foreign trade — both exports and imports — fell 13.9% last year.

Adele and David Bowie each win five Grammys

Wednesday, February 15, 2017

On Sunday, British singer Adele won five Grammy Awards at the 59th Grammy Awards event in Los Angeles. David Bowie posthumously won five Grammys.

Adele won Song of the Year, Best Pop Solo and Record of the Year for her song Hello, and Album of the Year for her album 25, becoming the first singer to win the Song of the Year, Record of the Year, and Album of the Year twice.

David Bowie was nominated in five categories — three for his album Blackstar in Best Alternative Music Album, Best Engineered Album, Non-Classical, and Best Rock Performance; and two for his song Blackstar, Best Rock Song and Best Rock Performance. Days after releasing his 25th album, Blackstar, Bowie passed away in January 2016, due to cancer. Before Blackstar, Bowie won a Grammy for his music video Jazzin’ for Blue Jean, and Lifetime Achievement Award in 2006, never winning the award in a major category before.

In the event, singer Bruno Mars paid tribute to music icon Prince, replicating style, costumes, and guitar of Prince’s. Minneapolis-based funk band The Time, who had performed with Prince, paid tribute to the singer who passed away in April at the age of 57. Adele, in her performance, paid tribute to George Michael. While performing, Adele stopped, swore, and restarted. She later apologised, saying “I am sorry for swearing and I am sorry for starting again, I can’t mess this up for him[…] I am sorry, I can’t.” British pop singer George Michael died on Christmas Day of heart failure at the age of 53.

Adele was in tears while receiving Grammy for the Album of the Year. In her acceptance speech, she said, “But I can’t possibly accept this award. And I’m very humbled and I’m very grateful and gracious. But my artist of my life is Beyoncé. And this album to me, the ‘Lemonade’ album, is just so monumental. Beyoncé, it’s so monumental. And so well thought out, and so beautiful and soul-baring and we all got to see another side to you that you don’t always let us see. And we appreciate that. And all us artists here, we fucking adore you. You are our light. And the way that you make me and my friends feel, the way you make my black friends feel, is empowering. And you make them stand up for themselves. And I love you.” Other albums in the pool, besides 25 and Lemonade, were Justin Bieber’s Purpose, Drake’s Views, and A Sailor’s Guide To Earth by Sturgill Simpson.

Earlier, while receiving award for the Record of the Year, Adele said, “My dream and my idol is Queen Bee [Beyoncé], and I adore you and you move my soul every single day and you have done for nearly seventeen years”. Other songs nominated in the category were Beyoncé’s Formation, Work by Rihanna, 7 Years by Lukas Graham, and Stressed Out by TWENTY ØNE PILØTS.

Beyoncé received the largest number of nominations for the event — nine — but she won only two. Her album Lemonade won Best Urban Contemporary Album and her song Formation won Best Music Video.

Chance The Rapper won Best New Artist, and claimed Best Rap Performance for No Problem and Best Rap Album for Coloring Book. Chance’s songs were never sold, and were available for free on streaming services.

The new host James Corden took a pratfall on the stairs while entering. The duo TWENTY ØNE PILØTS won Best Pop Duo/Group Performance for their song Stressed Out. Upon announcement, they removed their pants to accept the award. Sharing an incident of watching Grammys before the duo was famous, Tyler Joseph said Josh Dun proposed if they were to receive a Grammy, they would receive it in their underpants as they were in underpants watching the award ceremony at the time. In his acceptance speech, he said, “I want everyone who’s watching at home to know that you could be next. So watch out, because anyone from anywhere can do anything.”

Locating A Cell Phone With Gps?

By Vladimir Petrov

Recent developments in GPS technologies have incorporated GPS capabilities in the latest models of cell phones. Following the same complex algorithm that GPS devices use to locate points within a given map, smart phone owners can now detect their phone’s location based on the signals received from local transmission powers.

Since these mobile devices are enabled to send text messages, make calls, send e-mails and surf the internet, they can now enjoy the benefits of GPS functions particularly during emergency situations. This new set of functionality is true to both CDMA and GSM-based cell phones.

There are many ways in which a cell phone can be located using mobile phone-based GPS functionalities. Using the same satellite network and repeater triangulation algorithm, the system provides GPS-based locator services for various networks.

YouTube Preview Image

When cell phone features vary depending on its brand, GPS mobile phone functionalities vary depending on the service features offered by the network provider. This is because the system will locate your phone using the signals coming from the network’s transmission towers.

To perform a triangulation system of tracking, it would take about two or more transmission signal readings before a GPS-enabled phone will be located. From such feeds, the system will calculate the distance from where the signal may be coming from and work out the triangle that will fit signal strengths. This way, the third point, which is the actual location of the phone, will be determined.

With some phones, GPS transmissions will be sent when the person who has the phone has made an emergency call. This way, it will guide the police as well as the rescue people to immediately get to that location and administer aid. The accuracy of locating a cell phone via network GPS services is dependent on the strength of signals received, which could be a problem in areas like deserts, wastelands or un-populated countryside where the number radio masts is very limited.

Cell phones may also be tracked using web-based GPS applications. They also follow the same mechanisms used by their networks. To gain access to GPS technology, you need to register your phone to the website that supports, activates and runs on your phone’s platform. Fill out its agreement box and choose the download box that corresponds to your brand and model.

Later models of phones are now equipped with GPS chips. Plug in your phone to your computer and start the upload process. Set your preferences. After that, you can run a test on your phone’s GPS functions using the website’s supported electronic map format, such as Google maps.

Activating your phone’s GPS functions via web-based applications gives you the convenience of tracking your phone’s location based on the website’s up-to-date maps and points of interests.

In addition to civilians, companies are not using cell-phone GPS functions to enjoy practical solutions in enhancing the security of their employees, tracking their location especially when working in remote locations on their own. For concerned parents, this feature allowed them to keep track of their children’s location. Aside from locating phones, the additional perks of using GPS-enabled cell phones include convenience and ease in locating new restaurants, shops and other nearby points of interests

Dove ad viewed more than 3 million times on YouTube

Saturday, November 4, 2006

An advertisement for Dove beauty products has been viewed by well over three million people, without ever being on television. A copywriter from Ogilvy Toronto, the advertising agency that created a spot named “evolution”, uploaded the advertisement to video sharing website YouTube.

While the official upload of the ad itself has been viewed 1,119,262 times, there are dozens of copies of the ad on YouTube, adding to a minimum of 3,059,546 views. The official copy of the video is the website’s 12th most viewed this month, 53rd of all time.

Unofficial uploads have each received high levels of viewership, with 449595, 445322, 207906, 201670, 195265, 116501, and 102634 plays.

The agency did not originally intend to upload the video to YouTube, only display it on the company’s homepage. Staff member Tim Piper uploaded it to his account on October 6, about a week before it first got media coverage on Good Morning America.

The ad begins with a woman walking into a photo shoot. From there, she is primped and plucked by hair and makeup artists, then tweaked on a Photoshop-like program. The photo-manipulation is then posted on a billboard for the fictional “Easel Foundation Makeup” brand. Two young, teenage girls walk past, glancing at the board. “No wonder our perception of beauty is distorted” ends the ad in text, “Every girl deserves to feel beautiful just the way she is.”

The creative team for the ad included Tim Piper, Mike Kirkland, Janet Kestin, Nancy Vonk, directors T Piper (treatment and post production) and Yael Staav (live action) from Reginald Pike, Soho post production, Rogue editing, Vapor music, Gabor Jurina and Make-up: Diana Carreiro, and Reginald Pike.

The official French copy of the ad has only received 132 views, although it was only uploaded on November 2, 2006.

University of Southern California spit test predicts cavities

Monday, February 21, 2005

Los Angeles, California —A simple saliva test can predict whether children will get cavities, how many cavities they will get and which teeth are most vulnerable.

Developed by researchers at the University of Southern California in Los Angeles, the test quantifies the genetic component of tooth decay, spotting the risk when something can be done about it.

“When we apply this to young children, it allows us to predict what might be their future caries history—the number of cavities that they’ll get by, say, their late 20s or early 30s,” says researcher Paul Denny.

Called the Caries Assessment and Risk Evaluation (CARE) test, the test measures the relative proportions in saliva of different types of sugar chains called oligosaccharides. The same sugar chains are present on tooth surfaces.

The effect of sugar chains on teeth’s resistance to disease is analogous to the effect of “good” and “bad” cholesterol on blood vessels. “Good” sugar chains tend to repel bacteria that cause cavities while “bad” allow bacteria to bond to teeth and start the decay process. Unlike cholesterol, however, sugar chain makeup in humans is 100% genetically determined.

Denny and colleagues have found that the sugar chain makeup in saliva can predict a child’s future cavity history to plus or minus one cavity with greater than 98% confidence.

The findings suggest that in developed areas of the modern era genes play a more significant role in tooth decay than in former times or third world nations where gross malnutrition and negligent oral hygiene held the greatest impact on dental health.

Vestas protesters sacked with immediate effect

Thursday, July 30, 2009

Eleven of the 25 workers at the Vestas factory in Newport, Isle of Wight, England who have been carrying out a sit-in since Monday July 20 have been sacked with immediate effect.

According to one of the protesters known as “Mike”, the occupiers were given their dismissal notices concealed under slices of their evening meal of pizza. The company said that the protesters have had ample opportunity to air their point of view, and had no choice but to sack eleven of the twenty five workers that they had positively identified; and that given that the fact that the action constituted a “fundamental breach” of trust, that the eleven would not be entitled to redundancy packages. A press release from the company said that Vestas “saw no other choice than to dismiss the 11 employees, who the company has positively identified as the employees currently participating in the occupation of the factory.”

The protesters remained upbeat, vowing to continue their occupation and have called upon the UK government to save the 625 jobs and to nationalise the Danish owned factory. Occupier Ian Terry told the BBC that if the occupiers are forced out, they plan to leave the building “peacefully”.

Vestas management were dealt a setback today in ending the occupation as Newport County Court ruled that the papers accusing the occupiers of aggravate trespass and requiring they surrender the office they occupy by July 29 were improperly served. The case has been adjourned until Tuesday August 4. In court, Judge Graham White said he was “distinctly uncomfortable” with what he perceived as Vestas’ effort to “get around the rules” in retaking the factory from the occupiers.

Legal representation for the Vestas workers had been offered by Bob Crow, secretary of the RMT trade union. Crow has pledged the “full solidarity” of the RMT and seven other unions with the workers occupying the plant.

Vestas management has also been providing the occupiers with hot meals in an apparent response to Crow’s announcement, made on July 24, that the RMT was planning on airlifting food into the factory by helicopter. Crow is meeting today with Ed Miliband, the Environment Minister.

Earlier in the week, Miliband pledged £6 million in funding to an expansion of Vestas’ Isle of Wight research and development centre, which currently employs 110 workers and could, said the Minister, be expanded to employ 40 more.

Rallies continued throughout the week in support of the Vestas occupiers. Since the occupation began, the Vestas workers have received declarations of support and solidarity from a wide swathe of the British left, including but not limited to: political parties Green Party, Respect, the Socialist Party, the Socialist Workers Party, the Alliance for Workers Liberty, and the Communist Party of Britain; the TUCG group, which brings together the BFAWU, FBU, NAPO, NUJ, PCS, POA, RMT, and URTU; and environmental groups Greenpeace, the Campaign against Climate Change, Climate Camp, and Workers’ Climate Action, who claims credit for initiating the campaign to occupy the factory. Attendees of the Big Green Gathering, a large annual environmentalist rally which was due to take place starting today but was suddenly canceled on Sunday, are being encouraged to go to the Isle of Wight and take part in support rallies for Vestas instead.

Speaking to Wikinews about the “redgreen” coalition supporting the occupation, a spokesman for the Alliance for Workers’ Liberty said: “We think this struggle is important on at least three grounds — it is central to the struggle for jobs, it is central to the struggle for the environment, and it is central to the struggle for rebuilding the labour movement.”

Photographs shared with Wikinews by the occupiers show the occupiers, mostly young men, talking, carrying out everyday tasks, and keeping in touch with the outside world via mobile phones. The use of mobile telephones in the Vestas occupation has given the press remarkable access to the occupiers and provided an effective platform for relaying their demands and feelings to the media. In contrast, Vestas’s designated media contact for the United Kingdom is on vacation. Attempts to reach Vestas Newport factory manager Patrick Weir, whom a Vestas representative at the company’s Danish headquarters stated was handling press inquiries regarding the occupation, received no reply.

Vestas plans to close the factory on July 31, citing the difficulties of obtaining planning permission for wind farms in the United Kingdom. All blades manufactured at Vestas’ Newport plant are sent to the United States. 1900 employees of the company in Northern Europe face job losses, 625 of them in Vestas’s plants in the south of England.

Commercial Insurance, Understanding The Need &Amp; The Coverage

Submitted by: A.Noton

Commercial insurance is one of the most imperative investments that a business owner will ever make. This is the coverage that will protect assets, investments, and the very heart of the company. Below is some information on commercial insurance which you may find useful.

What is commercial insurance?

Business insurance is designed to protect the assets of businesses, and commercial establishments. There are commercial policies which are appropriate for all size companies. As well, policies may be tailored to meet the needs of the individual company itself.

What types of events does the business insurance protect against?

YouTube Preview Image

There are different policy options depending on need. However, most policies offer coverage against such things as, theft, fire, property damage, and general liability.

Does a small business need commercial insurance?

Though all businesses need such coverage, it may be especially important to the small business owner. If a company is not incorporated, owners may be at even greater risk in the event of unforeseen circumstances. Small business owners could lose not only business related capital, but more importantly, they could suffer a loss of personal assets should potential loss or law suits occur. This means assets such as the family home, vehicles, etc. could be in jeopardy. Business insurance will prevent this type of stress and hardship.

Does business insurance include workers compensation coverage?

Some enterprises may opt to purchase workers compensation policies through a different company than the one which provides them with fire, theft, and general liability coverage. However, often the same insurance company will provide for all commercial insurance needs. Many times it is less expensive to purchase all coverage from the same company. There often will be a package rate available. Which even you choose, be certain to purchase adequate workers compensation coverage. Workers compensation is the coverage that will pay for medical expenses of employees, should they become injured on the job. It is of the utmost importance to have this protection.

How to choose the best insurance company for your business

When searching for a commercial insurance company, the key is to find one that is reputable. They should be able to meet all coverage needs of the business, provide comparable rates, and have a reputation of providing excellent customer service, ease of claims, and prompt settlements. If you are considering purchasing insurance from a company check with the better business bureau. See what type of rating they have, and how many complaints have been filed against them. This will give you an idea of how reliable the firm is.

Before purchasing a commercial insurance policy compare rates, and offered coverage from multiple companies. Find agents who will take the time to address all your questions and concerns. This is imperative. A good agent will be willing to invest the time it takes to make certain that all aspects of coverage have been thoroughly explained. Once you have notes on several of the best insurance providers, narrow your choices down to the one that best meets the needs of you company.
