Proton Cars – Getting Savvy

Thursday, August 4th, 2011

Appius, in partnership with Marketing Matters, have been selected to promote the Proton’s new citycar – the Proton Savvy. The car hasn’t been officially launched yet but Appius have added a teaser promotion to the homepage. The teaser promotion allows website visitors to register their interest in the Savvy.This is just the latest installment of Appius’ website work for the Marketing Matters client; which includes, A Web Communications Audit to inform Proton’s online strategy Search Engine Optimisation Multimedia work on animated Flash headers for each Proton model and a 360 exterior view of the GEN-2 eMedia development work for the whole of the Visitor Interaction work to integrate the Proton Dealer Finder Systems Integration to pass data from the enquiry forms to the Proton call centre.

Most elements have between two and six stable isotopes. On the other hand, a few elements such as technetium have no stable isotopes. Twenty elements, inclusive of gold, fluorine, sodium, aluminum, and phosphorus, have only one stable isotope each. The element with the most stable isotopes is easy to remember because its name is almost the same as its number of stable isotopes such as tin, with 10. As for unstable isotopes, there are over 1,000, some of which exist in nature, but most of which have been created synthetically in laboratories. This number is not fixed; in any case, it is not necessarily important, because many of these highly radioactive isotopes last only for fractions of a second before decaying to form a stable isotope. Yet radioisotopes in general have so many uses, in comparison to stable isotopes, that they are often referred to simply as “isotopes.”

Volkswagen Ag May Share Technology With Proton

Thursday, August 4th, 2011

On a report that Volkswagen AG may have agreed to share technology with Proton Holdings Bhd., and to acquire a stake in its manufacturing unit, shares of the unprofitable Malaysian automaker rose. After the Edge magazine said that Volkswagen may pay several hundred million ringgit and supply vehicle platforms as part of an agreement, the stocks of Proton jumped as high as 5.2 percent. The report also said that the biggest carmaker in Europe, Volkswagen, will own 51 percent of a new company that will own Proton’s manufacturing division.

Analyst Mohd Hanafi said that the agreement seems to be just waiting for a formal decision. The analyst at Alliance Research Sdn. in Kuala Lumpur, with a “buy” rating on Proton stock, added that any kind of new positive development would surely have an impact on the share price. Based on the estimates of Hwang-DBS Vickers Research Sdn., the control of Proton’s car making division may cost 900 million ringgit (3 million). The state-owned automaker needs an ally to help roll out new models and turn out increasing sales.

Khazanah Nasional Bhd. spokesman Mohd Asuki Abas refused to comment on the report. Khazanah, a Malaysian government investment unit, holds 43 percent of Proton. Proton Spokeswoman Faridah Idris said that she was not able to comment immediately. Proton shares jumped as high as 30 sen to 6.10 ringgit. The stock has dropped 11 percent this year as compared with a 26 percent increase by the Kuala Lumpur Composite Index. The Magazine said that according to the agreement, Proton will control domestic vehicle distribution and Volkswagen will monitor international sales. Azman Mokhtar, the Managing Director of Khazanah, said in June 26 that he plans to look for a partner for Proton before the end of this year. The Edge also states that collaboration between Proton and U.S.

What is ucla proton prostate cancer treatment?

Thursday, August 4th, 2011

What is ucla proton prostate cancer treatment? We’ll talk about this prostate cancer treatment as belows,which is a very pupular,we need to know more about it. Traditional radiation therapy, three-dimensional conformal and intensity-modulated radiation therapy-based treatment is X-ray radiation to send ionizing radiation. In addition to the x-line, the electrons, protons and neutrons and other particles such as atoms can also be used for radiotherapy. Proton-line external beam radiation therapy Radiation therapy is a form of it, rather than using a proton x ray transfer ionizing radiation.

Proton line can be set to achieve a particular depth of the organization, as well to achieve this pre-set depth, the ionization level increased rapidly, Line by adjusting the proton energy, the ionization energy can be enveloping the entire tumor volume, resulting in tumor cell DNA damage, while maximizing protection of the surrounding normal tissues.

This is also the advantages of proton line, which could be better carried out three-dimensional tumor proper type with adjusting the proton linear energy. In addition, the proton line differs from traditional radiation, so that normal cells have the ability damaged white line repair, and tumor cells succumbed to irreversible damage beyond repair. Currently used proton line treatment for prostate cancer, with few clinical reports in the United States, only a few centers is carrying out this project. Preliminary results indicate that without recurrence rate of PEA is average 80.2%. Foci within the prostate smaller, the greater the probability of exposure, the greater the likelihood of a cure. Proton-line treatment for long-term effect remains to be seen. Before proceeding with a discussion of isotopes and their uses, it is necessary to address a point raised very often, when it is stated that some atoms do have the same numbers of neutrons and protons. In fact, nuclear stability is in part a function of neutron-to-proton ratio. Stable nuclei with low atomic numbers (up to about 20) have approximately the same number of neutrons and protons.

Wonders of Unstable Isotopes

Two atoms may have the same number of protons, and thus be of the same element, yet differ in their number of neutrons. Such atoms are called isotopes, atoms of the same element having different masses. Thus isotopes are atoms of the same element that have different masses due to differences in the number of neutrons they contain. The name comes from the Greek phrase ‘isos topos’, meaning “same place”: because they have the same atomic number, isotopes of the same element occupy the same position on the periodic table. Because the atomic number of any element is established, sometimes isotopes are represented simply with the mass number, thus: 93Ag. They may also be designated with a subscript notation indicating the number of neutrons, so that this information can be obtained at a glance without having to do the arithmetic. For the silver isotope shown here, this is written as Isotopes can also be indicated by simple nomenclature: for instance, carbon-12 or carbon-13.

Many isotopes are stable, meaning that they are not subject to radioactive decay, but many more are radioactive. The latter, also known as radioisotopes, play a significant role in modern life. Carbon-14, for instance, is used for estimating the age of objects within a relatively recent span of time—up to about 5,000 years—whereas geologists and other scientists use uranium-238 to date minerals of an age on a scale with that of the Earth. Concerns over nuclear power and nuclear weapons testing in the atmosphere have heightened awareness of the dangers posed by certain kinds of radioactive isotopes, which can indeed be hazardous to human life. However, the reality is that people are subjected to considerably more radiation from non-nuclear sources. Radioactivity is a term used to describe a phenomenon whereby certain materials are subject to a form of decay brought about by the emission of high-energy particles or radiation.
