A dentist is a medical practitioner who checks, diagnoses and treats issues and diseases commonly associated with the oral cavity and some of the areas around it. He or she goes to dentistry school to undergo four to six years of education and training. Among the many skills that the prospective oral health care practitioner should learn is how to use the various tools that come with the practice.

Tools for Examination The mirror is one of the most important instruments that a dentist can use during his or her examination of the patient. The mirror is actually a small circular shape that is attached to a metal rod. This allows the dentist to look at the teeth at various angles, especially the set of upper teeth and the backs and sides of some that are difficult to view without it. It guides the dental practitioner to see and assess the state of the teeth and gums of the patient. Probes are also used to assess the oral cavity. The dental explorer probes the crevices and niches of each tooth to seek out cavities and other imperfections. The periodontal probe is used o check out the patient\’s gums while the straight probe is used for various ways in seeking out imperfections that both the dental explorer and the periodontal probe cannot reach. Drills The drill is used to make cavities easier to access and treat. Some cavities have jagged edges that may not be easy to treat and cover with composite. The dental drill makes the edges as well as the sides of the cavities smooth to make it easier for the composite to bond with it and seal it. The dentist also uses the drill to sculpt and arrange the composite in such a way that it conforms to the corresponding tooth beside, below or above it. The sizes of the drill bits differ and they are used in accordance to the preferences and skill of the dental practitioner. Excavators These are instruments used to remove various substances and tissues from cavities in the mouth and its many aspects. A spoon excavator is used to decay which is soft and carious from the teeth. Another excavator is called the half hollenbach which is used to test for flash or overhangs in the tooth. Chisels are used by the dentist to bevel the maxillary. There are several different classes of these used in accordance to the preferences of the dental practitioner. Surgical Instruments are used for surgery and extraction of a tooth. Extraction and surgery is often performed by a dentist who is trained and skilled in surgery. Those who focus on cosmetic dentistry or orthodontics usually do not do surgery. These are just a few of the instruments and tools that a dentist can and will use to perform the various operations and treatments that he is trained to do. Other dental practitioners who have specialized in other fields of dentistry may have specialized tools as well. These may be developed by the dentist himself or developed by manufacturers to provide the needs of the practitioners.

Wikinews interviews Sue Gardner on Wikipedia blackout

Wednesday, January 18, 2012

This article mentions the Wikimedia Foundation, one of its projects, or people related to it. Wikinews is a project of the Wikimedia Foundation.

Today, the English version of Wikipedia is taking part in a 24-hour ‘blackout’ to protest two proposed U.S. anti-piracy laws, the Stop Online Piracy Act and the PROTECT IP Act. The protest mirrors similar actions from other websites including Reddit and Boing Boing. The White House stated on Saturday that they “will not support legislation that reduces freedom of expression, increases cybersecurity risk, or undermines the dynamic, innovative global internet”.

In the midst of the Wikipedia blackout, executive director of the Wikimedia Foundation Sue Gardner answered some questions posed by Wikinews’ Tom Morris about the effectiveness of, and background to, the blackout.

((Tom Morris)) Do you think the blackout is going to actually be effective?

((Sue Gardner)) Yes. In my opinion, the blackout has two main goals—to raise awareness about the dangers of SOPA and PIPA, and to encourage readers to contact their elected representatives and give their views. The first has already been accomplished: there are already more than 4,000 stories in Google News about the blackout, and it was a trending topic on Twitter almost immediately. So we know we’ve been effective in raising awareness. What remains to be seen how many people will contact their elected officials.

((TM)) What do you say to people who have decided to leave the editing community as a result of the blackout?

((Gardner)) I hope nobody stops editing Wikipedia because of the blackout. I watched the community decision-making process unfold on the English Wikipedia, and I thought it was a good one. People first started talking about SOPA more than a month ago. Jimmy started the straw poll in mid-December. Over 1,800 English Wikipedians from many different countries participated in the discussion over the last three days. As the admins who closed it noted, this is by far the largest-ever number of participants in a community discussion on English Wikipedia, and the overwhelming majority of them supported action. So I would hope that anybody who opposes the blackout would also agree that the decision-making process was a good one, and would therefore be okay to accept it, however reluctantly.

((TM)) How much technical planning went into the blackout before the community consensus was decided on Monday night?

((Gardner)) Last Thursday Geoff Brigham [Ed: Wikimedia’s legal counsel] asked engineering to do an internal assessment of the technical implementation requirements, because the community discussions at that point were suggesting there would likely be some kind of action. Engineering did an initial assessment based on e.g. the Italian blackout, implications for search engines, etc., and then a lot of work happened over the weekend. The bulk of initial development and testing happened on a sprint on Martin Luther King Day, a public holiday in the United States, and the final launch development and testing sprint happened on Tuesday.

((TM)) Does the fact that this is affecting only English Wikipedia and not the sister projects and other language projects concern the Foundation?

((Gardner)) No. My understanding is that the English Wikipedia is the only project and language-version enacting a blackout, but that several other projects and language versions are putting up supportive banners, with the Italian Wkipedians doing a clickthrough informational interstitial. The German Wikipedia decided to put up banners even before consensus was reached on the English Wikipedia, and the Arabic Wikipedia, Italian Wikipedia and Commons later made the same decision. (There may be others, that I don’t know about.) I think that’s fine: each project and each language has different circumstances that argue for different types of action, or for no action. There is no one right answer that fits everybody.

((TM)) Some have said that the lack of participation by opponents of SOPA in the commercial sector (sites of the size of Twitter, Facebook, Google etc.) is going to hamper the effectiveness of the blackout – is this a concern?

((Gardner)) No. I don’t think anybody ever expected the big commercial sites to black out: most aren’t in a position to participate in something like this even if they wanted to. For example, they might have shareholders to answer to, participation might cost them significant revenue, or it could break contractual agreements (such as a commitment to maintain a certain level of uptime, or some other service delivery). Most sites are constrained by various commercial considerations: that makes Wikipedia’s participation particularly powerful and important.

((TM)) Given both the Italian shutdown and the SOPA blackout, is the Foundation going to come up with a policy or set of conditions which limit when these kind of things happen? There are plenty in the community who support the SOPA actions but are concerned that this will set a bad precedent.

((Gardner)) Yeah, I empathize with those people and to a certain extent I share that concern. The Wikimedia movement does not have a lot of experience with advocacy, and probably mistakes will get made. At this time the Wikimedia Foundation doesn’t have any plans to develop policy governing protests or advocacy work. But, I think it probably does make sense for the Foundation to create venues for these discussions so people can share thinking and expertise. So for example, we may create a mailing list dedicated to advocacy/lobbying. And there is some good thinking starting to happen [on the project-wide protests page on Meta].

Black boxes from Air France Flight 447 localized

Thursday, May 6, 2010

The flight data recorder and cockpit voice recorder, or “black boxes”, from an Air France plane that crashed on June 1 last year in the Atlantic Ocean, have been localized to within about 2 square miles (5 square kilometers), a French official said on Thursday.

The French government and military officials have urged caution, saying there is no guarantee the flight recorders will be found. French navy spokesman Hugues du Plessis d’Argentre commented to AFP, “[I]t’s like trying to find a shoe box in an area the size of Paris, at a depth of 3,000m (9,800ft) and in a terrain as rugged as the Alps.”

The aircraft, an Airbus A330-200, carrying 216 passengers and 12 crew members, for a total of 228 people on board, crashed in the Atlantic Ocean after flying in bad weather. The pitot tubes, which measure airspeed, are considered likely to have been a contributing factor to the crash. However, the actual cause has yet to be determined.

The search is now in its third phase, which started on March 30 – April 1, 2010 and was originally announced to last 30 days. However, on May 4, the search was extended to May 25.

Tips On Choosing New Windows Arlington

byadmin

One of the most important elements on a home is the Windows Arlington. Most people will notice the windows of a home when they are first viewing the home’s exterior. Because of this, it is important to make sure the windows look good and are enhancing the look of the home. This will often cause people to see the remainder of the home in a favorable way.

When choosing replacement windows there are generally many different options a homeowner can consider. To help with this process it is important for the homeowner to have a good idea of the style of their home and the image they are hoping it projects.

Many people want a home to look natural and welcoming. Others may prefer a more modern looking home that looks stylish. Understanding these types of matters can help a homeowner in deciding on a particular style of window, the material it is made from, and the color it is finished in.

Very often people today who are looking for new Windows in Arlington will be striving to find windows that are energy efficient. This can be important for those who want to help conserve energy. It is also a good option for anyone who is hoping to find ways to decrease their heating and cooling costs.

When looking for windows that are energy efficient the material the window frames are made of can have significant impact. While wood frames do provide some insulation, generally, it cannot compare with the energy efficiency vinyl or fiberglass frames can offer. Not only are these materials resistant to the transfer of heat but these frames often have a hollow area behind the frame where extra foam insulation can be added. This can make the windows even more efficient.

Windowpanes are also important to consider. Rather than using single pane windows, it is generally best to purchase windows with two or more panes. This slows the transfer of heat coming through the windows and this can help in reducing the use of heating and cooling systems. In addition, many times an inert gas, such as Argon can be used to fill the gap between the panes. This further enhances their efficiency.

Choosing new windows for home is important. By choosing the right windows, the home’s appearance will be enhanced while energy usage decreases. For more information, please contact Aaa-glass.com.

Australian Maritime Safety Authority directs owner of APL England to search for, and recover, 50 cargo containers lost at sea off New South Wales

Saturday, June 13, 2020

This Monday, Australian Maritime Safety Authority (AMSA) has issued a direction ordering the owner of APL England, a Singaporian cargo ship, to search for, and recover, 50 cargo containers that were lost from their vessel off New South Wales, Australia last month; Australian Transport Safety Bureau (ATSB) has classified it as a “serious incident”. AMSA has identified a priority search area of about 1000km2 stretching between the Illawarra and Sydney’s southern suburbs. Drift modelling and analysis of container sightings following the incident indicates that missing containers could be in this area at water depth of up to 200m. Containers within the search area pose the most immediate environmental threat and may present a safety hazard for commercial fishers.

AMSA General Manager Response Mark Morrow said 15 containers had been recovered from the shoreline or towed in after being spotted floating off the coast, but 35 containers were still missing. The 50 cargo containers were spilled from the ship on May 24 as rough weather at the waters has been reported, which caused the vessel’s main engine to trip; resulting in loss of propulsion for a short time and the ship rolling heavily, up to 25°. Further investigations, according to a statement from AMSA, showed “inadequate lashing for cargo and heavily corroded securing points for containers on the deck”, which were the shipmaster’s responsibility.

Of the 50 spilt cargo containers, 26 were empty, according to reports. Further, another 75 containers were damaged but stayed onboard, according to a report from ABC. Some commenters had remarked this incident could have been avoided if the ship was loaded with the cargo more appropriately, such as with a lesser amount.

The AMSA surveyors conducted a seaworthiness inspection on May 26, with the ship docked at the Port of Brisbane anchorage (off Port Cartwright), to check the structural and operational condition of the ship following the collapse of container stacks on the deck. AMSA General Manager of Operations Allan Schwartz said the seaworthiness inspection would help inform if, and how, the ship might be brought safely into the Port of Brisbane.

On May 27, the ship was found to be fit to be brought safely into the Port of Brisbane by Maritime Safety Queensland and the Brisbane Harbour Master. The vessel was escorted into Moreton bay by two harbour tugs, one container salvage response vessel, two Queensland water police vessels and a Maritime Safety Queensland pollution response vessel. It arrived safely in port at midday, and was detained by AMSA on Wednesday night after its investigators discovered the cargo stowage deficiencies including inadequate lashing arrangements for cargo and heavily corroded securing points for containers on deck.

AMSA said in a statement that the ship will not be released until the issues are corrected. “These inspection findings are a clear breach of requirements under the International Convention for the Safety of Life at Sea (SOLAS). This is a now matter for the ship’s owner, American President Lines (APL), and the operator to rectify.” AMSA and Australian Transport Safety Bureau are conducting investigation into the incident; the final report is anticipated by the end of 2021 . AMSA continues to provide drift modeling and work with NSW Maritime, the lead agency responding to the incident’s shoreline impacts.

The ship master, 42-years-old Mohamad Zulkhaili Bin Alias, appeared at Wynnum Magistrates Court on May 29, 2020. According to the statement by AMSA, the offences filed against the shipmaster related to pollution and/or damage of the Australian marine environment as a result of poor cargo loading. Specifically the two charges that have been laid, as reported by ASMA, were

  1. “Section 26F of the Protection of the Sea (Prevention of Pollution from Ships) Act 1983 – Discharging of garbage into the sea contrary to the Act
  2. Section 141 of the Navigation Act 2012 – Master did not ensure that the vessel was operated in a manner that did not cause
    • pollution to the marine environment in the coastal sea of Australia or the exclusive economic zone of Australia and
    • damage to the marine environment in the coastal sea of Australia or the exclusive economic zone of Australia”

The orders also included the ship insurer company to pay $22 million as per the Protection of the Seas Act, before the ship can be released from detention at the Port of Brisbane.

This Friday, on June 12, the Brisbane Magistrates Court in Queensland, Australia has changed the bail conditions for shipmaster – he was now allowed to travel abroad. The ship continued to remain detained in Brisbane where Australian Maritime Safety Authority (AMSA) was investigating.

The new bail conditions allowed the ship master to leave the ship and travel abroad to Malaysia to resume his work, required him to appear in court in person when requested, and required that he would pay AUD60,000 of deposit to the court before his passport could be released to him.

On May 26, reports were received of face masks washing up in NSW between Magenta Beach and The Entrance. By May 27, the floating containers and their contents started polluting the beaches in Sydney, Australia. The AMSA released a statement in which it said the containers likely contained “medical supplies, household appliances and building materials”.

The Malabar Beach, Coogee Beach, Maroubra Beach, Bronte Beach and Bondi Beach were affected. Malabar beach was reportedly affected the most. The beaches were closed on Wednesday, May 27, and Council staff –rangers– as well as residents, including volunteers from Australian Seabird Rescue (ASR), cleaned-up what washed up on shore.

On Sunday May 31, a 12-meter container devoid of its shipment of “medical supplies, household appliances and building materials” washed up on rocks near South Maroubra Beach, in New South Wales, Australia.

The ASR branch coordinator commented on the environmental impact of the debris, by saying “It’s not going to biodegrade, it’s going to stay there for such a long time. These animals out in the ocean are going to choose to eat a lot of it as food. They don’t realise that what the ocean is providing isn’t good for them.”

The beaches were re-opened for swimming by 1st of June. After the beaches re-opened, visitors were advised to not pick up any debris (pictured). Some of the spilled cargo has also reached as far as the Central Coast, according to a report from ABC.

AMSA General Manager Response Mark Morrow said AMSA expected the owner and operator to respond to the direction with a detailed search plan in the coming days. “Failure to comply with this direction constitutes an offence under Australian law”.

The court matter was adjourned until July 24, to be mentioned at Brisbane Magistrates Court on the day.

Parents prosecuted after homeopathic treatment leads to daughter’s death

Friday, May 8, 2009

Thomas Sam, 42, and his wife Manju Sam, 36, from Sydney, Australia, are undergoing trial for manslaughter by gross negligence for the death of their nine-month-old child, Gloria. She died from infection caused by severe eczema after they shunned effective conventional medical treatments for homeopathy, a form of alternative medicine that has been described as pseudoscience. Articles in peer-reviewed academic journals including Social Science & Medicine have characterized homeopathy as a form of quackery.

Gloria developed severe eczema at the age of four months and the parents were advised to send the child to a skin specialist. Thomas Sam, a practising homeopath, instead decided to treat his daughter himself. His daughter’s condition deteriorated, to the point that the baby spent all her energy battling the infections caused by the constant breaking of the skin, leading to severe malnutrition and, eventually, her death. By the end, Gloria’s eczema was so severe that her skin broke every time her parents changed her clothes or nappy, and in the words of the Crown prosecutor, Mark Tedeschi, QC, “Gloria spent a lot of the last five months of her life crying, irritable, scratching and the only thing that gave her solace was to suck on her mother’s breast.” Gloria also became unable to move her legs.

Mr. Tedeschi also told the court that, over the last five months of her life, “Gloria’s eczema played a devastating role in her overall health and it is asserted by the Crown that both her parents knew this and discussed it with each other.” However, despite their child’s severe illness, and her lack of improvement, the Sams continued to shun conventional medical treatment, instead seeking help from other homeopaths and naturopaths. Gloria temporarily improved during the rare times they used conventional treatments, but they soon dropped them in favour of homeopathy, and she consistently worsened.

Allegedly, Thomas’ sister pleaded with him to send Gloria to a conventional medical doctor, but he replied “I am not able to do that”. The parents are also accused of putting their social life ahead of their child, taking her on a trip to India and leaving her to servants while embarking on a busy social schedule, and giving her homeopathic drops instead of using the prescription creams they had been given.

Gloria was finally taken to the emergency department shortly before her death. By this time, “her skin was weeping, her body malnourished and her corneas melting”, according to the Sydney Morning Herald.

Speaking in the parents’ defense, Tom Molomby, SC, said that, as the parents came from India, where homeopathy is in common use, they should be declared not guilty due to cultural differences.

Homeopathy is a form of alternative medicine which treats patients with massively diluted forms of substances that, if given to a healthy person undiluted, would cause symptoms similar to the disease. Typical treatments take the dilutions, with ritualised shaking between each step of the dilution, past the level where any molecules of the original substance are likely to remain; for homeopathic treatments to work, basic well-understood concepts in chemistry and physics would have to be wrong. There is no evidence that homeopathy is more effective than placebo for any condition.

Why You Need An Ice Dispenser For Entertainment Reasons

byAlma Abell

Ice beverage dispenser appliances come in many shapes and sizes. Many people opt for ice buckets over ice dispensers because they are much more affordable. The problem with ice buckets however is that the ice melts over time and this can really set you back in terms of budget. You would have to purchase enough ice to last you throughout the day, and this is not very practical. Ice dispensers keep the ice frozen at all times, so you do not have to keep refilling it as the ice melts and you can always have ice on hand. This is great for those who host summer parties and social gatherings, not to mention it is a very affordable appliance to run.

Why Purchase An Ice Dispenser?

Not many people have the time to make ice in preparation for a summer gathering. It’s time consuming and it also takes a lot of effort. Not to mention the water also takes hours to freeze. By purchasing an ice dispenser and filling it with bagged ice, you can remove all this hassle. Your guests will be able to grab the ice whenever they want, and the appliance itself is very easy to maintain. Simply hook it up to the nearest plug socket and your well on your way.

Consistently Good Ice Every time

Another great thing about having an ice dispenser is that you get the right amount of ice, every time. The dispenser releases the same amount of ice with every application, so you don’t need to worry about ice going all over the floor and melting. Simply place your glass under the nozzle, push the button and watch as the ice falls directly into the glass. Your guests don’t need to continually visit the freezer, and your dispenser can be place wherever you want for ease of access. This makes things a lot easier for both yourself, and your guests.

Affordability

Ice dispensers are relatively affordable to purchase. Some come with light up signs whereas others just come with the basics. Whatever you need, you can be sure to find one that suits your every need by visiting your local supplier.

Delta II launches GPS IIR-19 satellite

Saturday, March 15, 2008

A Delta II rocket launched at 06:10 GMT this morning, with the GPS IIR-19 navigation satellite. The spacecraft, which forms part of the US Air Force’s NAVSTAR Global Positioning System, has been successfully delivered into a Medium Earth orbit.

The rocket flew in the 7925-9.5 configuration, with 9 GEM-40 solid-rocket boosters, an Extra Extended Long Tank Thor first stage, a Delta-K second stage, a Star 48B third stage, and a 9.5 ft (2.9m) diameter payload fairing. Launch was conducted by United Launch Alliance (ULA).

GPS IIR-19, also known as IIM-6 and SVN-48, will be placed in plane A, slot 4, replacing the GPS IIA-15 satellite. IIA-15 was launched in September 1992, and has been operating for over twice its design life. This was the 135th launch of the Delta II, and the twelfth orbital launch of 2008.
