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.

    Colleges offering admission to displaced New Orleans students/AL-KY
    See the discussion page for instructions on adding schools to this list and for an alphabetically arranged listing of schools.

    Due to the damage by Hurricane Katrina and subsequent flooding, a number of colleges and universities in the New Orleans metropolitan area will not be able to hold classes for the fall 2005 semester. It is estimated that 75,000 to 100,000 students have been displaced. [1]. In response, institutions across the United States and Canada are offering late registration for displaced students so that their academic progress is not unduly delayed. Some are offering free or reduced admission to displaced students. At some universities, especially state universities, this offer is limited to residents of the area.

    French workers use threats in compensation demand

    French workers use threats in compensation demand
    Posted in Uncategorized | July 2nd, 2020

    Friday, July 17, 2009Following similar threats by workers at New Fabris and Nortel, workers at JLG in Tonneins, France, threatened to blow up several platform cranes. The JLG factory announced in April 2009 that it will fire 53 of its 163 workers by the end of 2009, while the remaining 110 jobs will not be secure over the next 2 years.

    JLG Tonneins was acquired in 2006 with its parent JLG Industries, a maker of aerial work platforms, by the U.S.-based Oshkosh Corporation. Despite being hugely profitable in the past, production has been much reduced since 2008 with the contraction of the construction industry and lower demand for its products. Despite excellent past results the new American management demanded sweeping cuts at the company.

    In the view of locals, “the company’s actions are a disgrace given the expensive perks, such as official cars, for its corporate fat cats, compared to the sacrifice, silence, and dignity demanded by the company of those it has made redundant.”

    The management offered severance pay of 3,000 (US $4,200), however the workers demanded a severance package commensurate with “the wealth that their labor has generated.” Worker’s delegates requested a “supra-legal” payment of € 30,000, on Thursday 16 of July the management responded with a counter offer of € 16,000. On Thursday night the worker’s actions secured the € 30,000 settlement initially demanded.

    Darling announces UK budget for 2009
    Posted in Uncategorized | June 26th, 2020

    Thursday, April 23, 2009

    The United Kingdom Chancellor of the Exchequer, Alistair Darling, yesterday announced the 2009 budget. The budget is an annual audit of the nation’s finances, and decides what should be done with taxpayers’ money.

    The chancellor fell under scorn for his GDP growth forecasts, which are considered to be too optimistic in predicting that Britain will bounce back from its weakest economic performance since the end of the second world war. Darling forecast GDP growth of 3.5% in 2011, even after he was made to downgrade his predictions. He expects a record expansion of 1.25% next year, but chief UK economist Howard Archer disagrees, calling Darling’s predictions “mildly optimistic in the near term and much more optimistic in the long term.”

    HAVE YOUR SAY
    Was the increase in the ISA limit “too little, too late”?
    Add or view comments

    His plans for savers and pensioners, however, were commended by many, though was also criticised by a large portion of the populace. In the budget, Darling increased the amount that savers can put into an Individual Savings Account (ISA) from £7,200 to £10,200, of which £5,100 can be saved in cash. These increased limits will be available only to people aged over 50 from 6 October this year, and will not be available to everyone until 6 April next year. A number of financial experts described the move as being “too little, too late”, and Rumina Hassam, of price comparison website uSwitch.com, said: “The government’s decision to increase the cash ISA limit by £1,500 to £5,100 for the over 50’s is a just another kick in the teeth for the majority of savers as they will have to wait even longer to benefit. There is no doubt that savers have been sacrificed as a result of the plummeting base rate, bringing savings rates to an all time low.”

    Can You Get Hard To Find Ammo At A Pawn Shop In Saint Joseph, Mo?

    Posted in Construction Equipment | June 24th, 2020

    byAlma Abell

    If you have a firearm that requires some kind of ammunition that is not easy to find or if you are looking for a specific type of ammunition that serves a particular purpose, you need to look somewhere that specializes in that sort of thing. You might not think it, but a pawn shop is a great place to find hard-to-find ammunition. It is a great place because people often take their old firearms and ammunition to sell when they don’t need them anymore. Furthermore, some firearms stores liquidate their assets that way when they need to restructure.

    Rare Calibers

    There are two types of hard-to-find ammunition; there are rare calibers and there are rare types of ammunition. A rare caliber is usually one that is an old type of rifle or handgun. Some of them have come back into favor as of late; the .45-70 government is an example. It is not nearly as difficult to find as it used to be. You can still get a better deal on .45-70 at a pawn shop in Saint Joseph, MO than you would at a store. The ammunition that they sell is often a little bit older and thus less expensive.

    You can find other rare calibers at American Gold Mine Pawn. For example, you can sometimes find the original .52 caliber rounds for a Sharps rifle. Many reproductions have been chambered for .45-70, but the authentic versions still use the .52 caliber round.

    Specific Ammunition

    You can also find some specific types of ammunition at a pawn shop. For example, if you have an older firearm, you might need a black powder round instead of the smokeless powder round. These rounds pack less pressure and thus put less stress on your firearm. These are just a few of the types of rounds that you can find at such a shop.

    Wikinews interviews Stephen Murphy about the upcoming by-election in the Higgins electorate of the Australian parliament

    Wikinews interviews Stephen Murphy about the upcoming by-election in the Higgins electorate of the Australian parliament
    Posted in Uncategorized | June 23rd, 2020

    Tuesday, December 1, 2009

    With two by-elections coming up in Australia, many minor parties and independents will be looking to gain a seat in the House of Representatives. Stephen Murphy is one of the independents.

    Mr Murphy is a computer programmer from the Melbourne suburb of Brunswick.

    “After growing up in South-East Melbourne I studied Science at Monash with first class Honours, worked in Europe for 10 years and have recently returned to Australia. I work in finance as a computer programmer and speak five languages,” Mr Murphy said.

    Wikinews reporter Patrick Gillett held an exclusive email interview with Mr Murphy, candidate for the Division of Higgins.

    ((WN)) Why do you want to get into parliament?

    Stephen Murphy: I am standing up for what I believe is the correct course of action on the biggest issue in Australian politics in 100 years – Kevin Rudd’s flawed emissions trading scheme (ETS).

    ((WN)) What would the three main policies you are taking into this by-election be?

    SM: I will oppose the emissions trading scheme, ensure that all government policy is based on accurate scientific evidence and return common sense to Canberra

    ((WN)) How would you address these policies?

    SM: By asking for a Royal Commission into climate change so that the facts (such as that global warming stopped in 2001 and the emissions trading scheme will not change the climate one bit) are openly presented to the Australian people.

    ((WN)) Sending asylum seekers to Indonesia: good or bad?

    SM: Any government policy that does not properly consider all implications (be it emissions trading, or any other issue) is a bad one.

    ((WN)) Is the Australian dollar’s near parity with the US dollar a sign that the Australian economy is healthy, the US economy in chaos or both?

    SM: It’s a sign of both. Many countries around the world look with envy at how well (relatively) Australia is doing, to our credit! It is of concern that the American economy is in such bad shape and that their levels of debt seem unsustainable.

    ((WN)) How do you rate the governments economic stimulus package?

    SM: The economic stimulus package was poorly targeted and poorly carried out. When we could have been building roads, dams, railways and hospitals yet instead we were paying for tattoos, PlayStations and overseas holidays.

    ((WN)) Should it be wound back?

    SM: The question about levels of stimulus spending is a complicated one and requires expertise in economics, however one could say in general terms that all government spending should be well targeted and spent in the most efficient way.

    ((WN)) Is Kevin Rudd a better Prime Minister than John Howard?’

    SM: Australian voters are the best judge of that and we will know in 2019 🙂

    ((WN)) Is the Carbon Pollution Reduction Scheme an effective solution to climate change? Why?

    SM: Absolutely not. The CPRS will not change the climate by any amount that we can measure – it’s just a new tax that will hurt Australians and drive businesses and jobs overseas. Since 2003 there has been mountains of new scientific data which contradicts the popular theory that human carbon dioxide emissions are causing significant global warming. Recently, many of the scientists who wrote the IPCC report (on which the ETS / CPRS is based) have been reported as manipulating scientific data to create scary global warming scenarios. The science is definitely not settled

    ((WN)) Is there a better solution?

    SM: We can very easily refocus the momentum and goodwill that has been generated on climate change and channel this energy into other worthwhile environmental projects in Australia that will make a difference.

    ((WN)) Why should the electorate vote for you?

    SM: I will oppose the ETS and support responsible environmental policies instead of radical environmental policies that could end up costing every Australian taxpayer $4550 per year in new taxes.

    In pictures: Japan earthquake and tsunami
    Posted in Uncategorized | June 23rd, 2020

    Friday, March 18, 2011

    A week ago today, at 2:46 pm JST, a magnitude 9.0 earthquake struck off the coast of the T?hoku region in Japan. The earthquake created an extremely destructive tsunami that spawned 10 metre (33 ft) high waves just moments later. The tsunami travelled 10 km (6 mi) inland causing massive destruction in the country’s northeast, including crippling a nuclear plant.

    The earthquake and resulting tsunami have left 5,692 dead and over 9,506 missing, with nearly 450,000 homeless. The death toll is expected to rise.

    In this special photoessay, Wikinews looks at the earthquake and tsunami, the destruction that resulted and efforts to bring aid to the Japanese people.
