Pros And Cons Of Over The Counter Whitening Products And Professional Teeth Whitening In Norwood

byadmin

If your teeth are stained or discolored, you may have wondered what you can do to whiten them. The most common ways to whiten teeth are by using over the counter whitening products or having a professional Teeth Whitening in Norwood done at your dentist’s office. What are the pros and cons of store-bought whitening products and professional whitening services?

Whitening toothpastes, gels, and strips

Many toothpastes claim to whiten teeth, but most of them do not contain any substances that actually whiten teeth. They remove recent surface stains, but are unable to penetrate long-standing stains. Whitening strips are adhesive bands that are placed onto the teeth in the front of the mouth. The strips contain small amounts of bleaching agents like peroxide. Whitening gels are placed into dental molds and worn in the mouth for 10 to 20 minutes. Gels also contains natural whitening substances or bleaching agents, but in a slightly higher concentration than those found in strips. These products are relatively inexpensive and are more effective for people who have minor discoloration or to help maintain the results of professional whitening. Those with more pronounced yellowing may not see a big difference in color after using these types of products.

Professional Teeth Whitening in Norwood

Any type of whitening agent can cause tooth sensitivity, or exacerbate an existing sensitivity. Some people may not be able to get professional whitening because of extreme sensitivities, so it is important to talk to your dentist about this before you consider any type of whitening product.

Copiapó, Chile mining accident: in depth

Wednesday, October 13, 2010

The rescue of the Chilean miners trapped in the San José Mine in Copiapó, codenamed Operación San Lorenzo (San Lorenzo Operation), began on Tuesday night, at around 20:00 local time (23:00 UTC).

Florencio Ávalos was the first miner to be rescued, at 00:12 local time (03:12 UTC) on Wednesday. He was wearing a shirt signed by all his fellow miners. “The first miner is already with us. We saw it all, him hugging his wife Monica and his son Byron,” said President Piñera shortly after the first rescue. “We still have a long journey.”

“This will be recorded on every single Chilean heart forever,” Piñera added. “I hope the miners’ hope stay with us, just like the [February] earthquake victims’ [hope] and what the earthquake took off. We know that the disasters unite us all.”

All the 33 miners were rescued. The last miner, Luis Urzúa, was rescued at 21:55 Chile time (00:55 UTC). “It is a pleasure to be Chilean, [I’m] proud,” said Luis Urzúa to President Piñera. “In honour of the miners, their families, the rescuers […] let’s sing our national anthem. Viva Chile Mierda!,” said Piñera. Urzúa thanked Mining Minister Golborne and the First Lady Cecilia Morel for “fighting for their lives.” “I’m proud of my fellow miners,” Urzúa added.

Six rescuers, including a miner and a paramedic, descended to the miners’ shelter using the Fénix 3 capsule which was specially constructed for the rescue. They performed check-ups and talk with the miners before taking them back to the surface. The rescuers still don’t leave the mine.

The Fénix 3 capsules are 3.95 metres in height and weigh about 460 kilograms. They have an armour, an oxygen tube and a microphone. The occupants helmets contain an intercom to keep them in contact with the rescue team on the surface.

President of Chile Piñera assisted to the rescue. Bolivian President Evo Morales could not attend Carlos Mamani’s rescue. Mamani is the only Bolivian miner in the group.

A mass for the miners was conducted at 18:00 local time (21:00 UTC). The rescue takes between 15 and 20 minutes for each miner.

On Tuesday, Mayor of Copiapó Maglio Cicardini announced that the municipal schools in the city will have no classes this Wednesday “to transform the rescue of the Atacama’s 33 in a familiar meeting,” Radio Cooperativa reported.

“The miners will be taken to the Copiapó Regional Hospital for medical checkup, where they will have to stay for 48 hours,” Health Minister Mañalich said to Televisión Nacional de Chile.

Celebrations are taking place in several Chilean cities. In Santiago de Chile, people gathered in one of the most important points of the city, Plaza Italia. In Pichilemu, tens of cars are passing over its most important streets. In Copiapó, people gathered in its main square to assist a massive concert.

On August 5, 33 miners were trapped more than 700 meters (2,300 ft) underground, in the San José copper–gold mine, located about 40 kilometers north of Copiapó, Chile.

The youngest trapped miner is 19 years old, and the oldest is 63. There were several rescue attempts before reaching the miners’ shelter on August 22. The National Emergencies Office of Chile (ONEMI) released a list of the trapped miners on August 6, which included Franklin Lobos Ramírez, a retired footballer.

Chile is the worlds top producer of copper, according to The Economist. The San José Mine is owned by the San Esteban Mining Company (Empresa Minera San Esteban). The mine was closed down in 2007, after relatives of a miner who had died sued the company executives, but the mine was re–opened in 2008.

It was originally estimated that “it would take three to four months to complete the rescue of the trapped miners”. There were three plans to reach the miners: “Plan A” using a Strata 950 drill, “Plan B” using a Schramm T130XD drill, and “Plan C” using a RIG-422 drill. The first to reach the miners was “Plan B”, early on Saturday 9.

The last step of their rescue, announced by Health Minister Jaime Mañalich, was originally due to begin on Tuesday. Laurence Golborne, Minery Minister said “If it is possible, and the cement sets before and we don’t have any impediments to doing it, it would be wonderful,” in a press conference on Monday. The men will be extracted in a steel rescue capsule 54 cm (21 inches) in diameter.

On September 4, Chilean filmmaker Rodrigo Ortúzar announced plans to film a movie about the accident, called “Los 33” (“The 33”). The film will be released in 2011.

One miner is Bolivian, and the other 32 are Chilean.

Raúl Bustos, 40 years old, is an hydraulics engineer. He left his job in Talcahuano after the February 27 earthquake to work in the mine.

Daniel Herrera, 27 years old, is a lorry driver. He has acted as paramedic assistant in the mine. He said to La Tercera “the miners were unhappy with the psychologist in the rescue team.”

African nations gather to support a ban on cluster bombs

African nations gather to support a ban on cluster bombs

Thursday, April 3, 2008

A 39-nation coalition in Africa passed a declaration on Tuesday to ban cluster bombs in a nearly unanimous vote. The gathering in Lukasa, Zambia was the first meeting of the Cluster Munition Coalition (CMC) in Africa.

“Africa is ready for Dublin,” summarised Zambian delegate Robert Mtonga, referring to the upcoming May 19-30 meeting in Ireland to discuss a global ban on the weapons. “Too often Africa’s voice is pushed to the margins in international decision-making. But in banning cluster bombs worldwide, a common African voice will speak volumes and win the day”.

Too often Africa’s voice is pushed to the margins in international decision-making. But in banning cluster bombs worldwide, a common African voice will speak volumes and win the day.

Mtonga was critical of South Africa, the lone voice against Monday’s decision and the continent’s largest producer and stockpiler of cluster bombs, and called on the country to destroy its munitions and join the coalition to outlaw their use. Egypt, the only other African nation to produce the controversial weapons, voiced support for the ban.

“Strong political will” was credited with the resolution, by CMC co-ordinator Thomas Nash in recognising the drive “to stop the proliferation of this outdated weapon”.

In a released statement the CMC said that 19 African countries, including South Africa, have endorsed the Wellington Declaration. The Wellington Declaration is the basis for the upcoming negotiations at the Dublin Diplomatic Conference in Ireland in May.

While countries such as Germany and the United Kingdom have tabled the idea of a “transition period” during which time cluster bombs would remain a legitimate weapon of war, the African delegation was resolutely against the idea, calling for an immediate ban.

Cluster munitions are dropped from aircraft, opening in mid-air and releasing a large number of smaller explosives over a wide area. Writer Theodora Williams stated that their use usually results in “…the death and maiming of thousands of innocent civilians”.

There are currently 13 African nations that possess cluster bombs although Uganda has recently announced they are destroying their stockpiles. The weapons have been used in eight African conflicts in the past 35 years. In addition to Ethiopia, Morocco, Nigeria and the Sudan, other nations known to have used the weapons are the former Yugoslavia, Eritrea, France, Israel, the Netherlands, Russia, Saudi Arabia, Sudan, Tajikistan, the United Kingdom and the United States.

According to the San Francisco Chronicle, the United States, China, Russia, and Israel have resisted any ban on cluster bombs, arguing that they can be used in self-defense. The San Francisco Chronicle reported that the United States has lobbied allies to create loopholes in the upcoming Oslo treaty, to allow for the use of cluster bombs. Reuters reported that a U.S. official had stated that cluster bombs should not be banned if they are used responsibly in state conflicts.

In October 2007, Uganda became the first African country to state it would destroy its cluster bomb stockpiles. Uganda has announced a pan-African meeting to take place after the Dublin meeting, which would seek to garner support for the signing of a treaty in Oslo set to take place in December 2008. The weapons have been used in eight African conflicts in the past 35 years.

The CMC is an international network composed of over 250 civil society organizations in 60 countries, with the stated aim of protecting civilians from cluster munitions. Members of the CMC have been working to complete an international treaty to ban cluster munitions by 2008.

At the February CMC committee meeting in New Zealand, only 82 of the 122 nations present endorsed a draft ban on the production, usage or storage of cluster bombs.

The Basics Of Automated Meter Reading

byadmin

Most municipal water companies in the United States have converted all analog types of water meters to fully automated smart meters. This is true for both urban areas as well as rural areas.

By automating the monthly or alternate monthly meter reading process, municipalities were able to save cost in labor, fuel, and vehicles. Additionally, with accurate readings each month rather than estimates on alternate months and the risk of human error in the reading process, they recovered the cost of the installation of smart meters.

Today, property owners and property managers can take advantage of the same technology. Smart meters installed as submeters on individual units in residential or commercial properties allow for automated meter reading by utility billing companies. As part of the service, these companies prepare and email bills to tenants and even manage payments, eliminating the need for the property owner or manager to handle this on a monthly basis.

The Installation Process

For apartments, townhomes, condos, manufactured home communities and other types of residential or commercial applications, a smart meter located on the main water line into the unit is required for automated meter reading services. This meter can be installed indoors or outdoors. It is small and compact and can be installed in existing plumbing systems or at the time of new construction.

The Meter Reading Process

Through the smart meter, the automated meter reading is completed through the transmission of data over a secure network, which is separate from any home WiFi or internet service. The transmission of data is controlled by ANSI standards and uses specific communication protocols developed by the IEC or International Electrotechnical Commission.

The utility billing company receives the transmission from the smart meter on a schedule. The meter only records and transmits the amount of water used by the unit; it cannot monitor use by individual appliances or fixtures.
