Sistem Bedah Robotik Bantu Dokter Bedah Mengoperasi Jantung Manusia Yang Masih Berdetak

Jantung adalah salah satu organ penting bagi kehidupan manusia. Ketika jantung berhenti berdetak, artinya seorang manusia telah lepas dari kehidupannya. Tapi tak jarang pula di dunia kesehatan, ditemui banyak keluhan mengenai penyakit jantung yang diakibatkan oleh berbagai hal, salah satunya bisa jadi karena pola makan kita.

Tentu untuk bisa mengobati penyakit jantung adalah hal yang sangat sulit, bahkan untuk seorang ahli bedah sekalipun, mengoperasi jantung yang sedang berdetak sama artinya berjudi dengan nyawa seseorang. Hal tersebut bahkan bisa menyebabkan kematian.

Tapi tampaknya resiko tersebut mungkin suatu hari nanti akan dapat diminimalisir dengan adanya sistem bedah robotik yang kini masih terus dikembangkan oleh sejumlah peneliti di Montpellier Laboratory of Informatics, Robotics and Microelectronics di Perancis. Sistem robotik ini dipadukan dengan sistem 3D modelling yang mana dapat melacak gerakan jantung seperti detak jantung.

Bahkan nantinya sistem ini ditargetkan untuk dapat menyesuaikan hal-hal seperti gerakan dinding dada pasien ketika bernafas dan memprediksi gerakan dalam satu langkah saja. Ketika nantinya jantung dipasangkan dengan lengan robot ini, sistem akan beroperasi secara efektif membiarkan dokter bedah melakukan pekerjaannya untuk mengoperasi jantung. Tentu dengan adanya sistem operasi jantung ini nantinya akan sangat membantu di dunia kesehatan. Wah, semoga saja ya sistem robotik ini dapat segera diselesaikan oleh para peneliti, supaya nantinya para dokter dapat lebih mudah melakukan pekerjaannya dan kemungkinan sembuh bagi para pasien penyakit jantung pun akan meningkat.

Windows 7 RC to Have Shutdowns on March 1 '10

Last week the news made the rounds of the Windows 7 RC having a longer than average trial period. Stated clearly by Microsoft is that the Release Candidate install will remain valid until June 1, 2010.

What wasn’t so clearly publicized is the small detail that starting March 1, 2010 there will be bihourly shut downs of any installs of Windows 7 RC.

As Microsoft details on its partner site regarding the shutdown schedules for the beta and RC:

To avoid interruption, it’s recommended that you and your customers rebuild test machines by using a valid Windows operating system before Windows 7 Beta and Windows 7 RC expire. Windows will automatically notify you that the expiration process is about to begin. Two weeks later, your PC will shut down every two hours. For Windows 7 Beta, the bihourly shutdowns will begin July 1, 2009. The software will expire August 1, 2009. For Windows 7 RC, the bihourly shutdowns will begin March 1, 2010. The software will expire June 1, 2010.

So there you have it. While Windows 7 RC will be useful for 13 months as we all thought last week, it’ll be more useful for the first 10 months.

If there’s any confusion regarding what bihourly means – if it’ll be shutdowns every 30 minutes or 2 hours – it’s the longer of the two options, though probably still annoying enough to make one want to upgrade to the final version.

Windows 7 RC is set for a public launch tomorrow. Look forward to it! (Unless you’ve already downloaded it.)

Prophylactic Thunderstorms

Electricity is one form of energy. Many events occur in the power of nature all this, including lightning / thunder. Flash / lightning spark the high-voltage electricity that occurs in the earth's atmosphere is actually the electrical energy exemption. Ordinary lightning storms occur when rain accompanied by thunder and sometimes in the snow storm, dust storms, volcanic eruptions, and at the nuclear explosion.

Flash that occurs when rain storms come from the electrical loads that arise from the flow of air in the cloud. Perbadaan hoarding loads kilatan generate electricity in the lightning cloud, cumulus that between one another or between a cloud with the earth. Lightning usually occurs in the height of about 10 km and rise to five to ten kilatan in a minute, but most are not visible because it occurs in the cloud.

Sometimes lightning reaches the earth and can cause fire, injury or cause death to humans. One of the nature of the electricity load is a mutual attraction between positive and negative loads. Nature of this prophylactic tool is used to attract lightning and thunder to their land before the lightning strike the building. There are several kinds of lightning prophylactic tools are usually used, namely:

Franklin Rod, the tool is a copper cone with the form of protection with cone angle peak of the imaginary 112O. In order for the protection of, Franklin rod is placed on the iron pipe (with 1-3 meters high). The Franklin rod away from the weak protection in the protection of these areas. Franklin rod can be seen as pillars in the building rooftop.
Faraday Cage, To overcome the weakness because of the Franklin Rod areas that are not protected and the protection of the weak when the distance away from the Franklin Rod is then made Faraday Cage system. Faraday Cage have a system such as the nature and Franklin Rod, but the whole installation in the roof surface with a high pole lower.
Corona Ionization this system is interesting for lightning to strike his head with the ion-ion emit into the air. Ion density has a greater distance if close to the head. The ion generator can use electricity or Battery backup (generated ionization) or natural (natural ionization). Area protection system in the form of a ball with radius at approximately 120 meters radius, and this will decline in line with the increasing age. This system can be identified from his head, surrounded by a strip of 3 different voltage and high-mounted on the pole.
Radioactive although lightning is the best carrier system, but its use has been prohibited because radiation can disrupt the dipancarkannya human health. In addition, this system will be reduced radius pengamanannya with time according to the radioactive nature.

Thunderstorms are drawn and then channeled into the ground. Various conductor that can be used to drain off energy to the ground and lightning characteristics of the main frame is steel (prone to dropping out / failed connection that causes lightning vault cash and the induction currents in the lightning round), bare copper (no induction currents in the lightning round flow ), and coaxial cable ( induction currents in the cable).

While for the grounding terminal, can be a copper rod, copper plates or copper cone, the wide surface of the terminal and the lower the custody of land, then the better system grounding.
