Murata Seiko-Chan is a Robotic Female Kindergartener

Back in 2005, a liitle robot boy riding a bicycle called "Murata Seisaku-kun" made its debut at CEATEC Japan. This year at the same event, its developer Murata Manufacturing Co.Ltd. presents a unicycle-riding robot girl called "Murata Seiko-chan". At 20 inches in height and 11 pounds in weight, this little robot has a fictional story of its own. According to Murata, Seiko-chan was born on September 23 and is Seisaku-kun's paternal younger cousin. She's an "active but very shy" kindergartner whose dream is to go round the world cycling together with Seisaku-kun.

Seiko-chan's story was probably drafted in order to engage children, as that isMurata's aim in the first place. Seiko-chan was made for visiting class presentation to show kids that sciences and technology are fun. The robot that has a speed of 5cm per second uses a pair of gyro sensors for balance, ultrasonic sensors to detect obstacles, bluetooth module for wireless controlling, and in its chest is a rotating flywheel that helps it turn left or right.

Discovery HIV Vaccine

Result study experiment vaccine along 16.000 denizen Thailand contribute new hopefullnes for intercept AIDS epidemy, this vaccine become establish remissive be infected HIV risk. Over 25 years variously defise HIV/AIDS vaccine be over disappointed, the HIV/AIDS cases as though descry stymie.This research confederate canary pox vaccine ALVAC and AIDSVAX, this vaccine be based HIV strain B and E that dominant in Thailand.

Research previously two vaccine that effectless if severally, result study latest adduce that vaccine 31,2% effective remissive be infected HIV risk. This is the first demonstration HIV vaccine be able provide protection for this infect, this is progress science importantly. This study contribute hopefulness making vaccine that effective in global, said Colonel Jerome Kim, US Military HIV Research Program. Experimentation with in quantities in the world that enforceable by US Army and Public Health Departement Of Thailand. Since 2003 vaccine given to man and woman with age 18-30 years and not infected HIV, be located two province of Thailand, have level high risk to infected HIV. Partly volunteer received vaccine and other received placebo (not vaccine), 51 guys from 8.197 volunteer that received vaccine be infected HIV, while placebo group 74 guys from 8.198 to be infected HIV. This result study be accepted enthusiastic by Precident and CEO International AIDS Vaccine Initiative Dr. Seth Berkley give expression, so far as AIDS vaccine just be used to animal specimen but this research HIV vaccine be used to human that is to say protection effect vaccine for HIV to human. HIV vaccine researchist from Imperial College London, Dr. Adriano Boasso with effectiveness have to get up to along 70%.
World Health Organitation (WHO) in the communique profess this research is significant but problematical get permission medicament production licence, if have a basis on the result study mentioned, as yet be required study more what that vaccine have same effect to other hemisphere. In Point of fact over 50 candidate vaccine already be tested just two get away to next examination and achievement dissatisfy, adn extant along 30 vaccine queue to be examined.

COROT-7b

Corot-7b, previously named Corot-Exo-7b is a reported exoplanet orbiting around the star Corot-7. It was detected by the French led Corot mission in 2009. It is the smallest exoplanet to have its diameter measured, at 1.7 times that of the Earth. The mass of Corot-7b is about 5 Earth masses. Together with the observed radius, it is possible to exclude that the planet is made purely of iron, but other compositions, including a predominantly rocky one, are possible. it orbits very close to its star with an orbital period of 20 hours. the star, in the constellation monoceros, is 150 parsecs away and is slightly smaller than the Sun.

The planet has a high surface temperature, between 1000 to 1500 °C or 3600 °F. Due to the high temperature, it may be covered in lava or water vapor. The composition and density of the planet are still being examined, wih one possibility being that it is rocky like earth. It may also belong to a class of planets that are thought to be made up of water vapor and rock in almost equal amounts.

The scientists are unsure whether it is an ocean planet, a kind of planet whose existence has yet to be proven so far. In theory such planets would initially be covered partially in ice and they would later drift towards their star, with the ice melting to cover it in liquid.

A Single Firewall and Multiple Subnets

One way to segment the network without introducing another firewall is to use multiple interfaces on the firewall to create several subnets. A design base on this principle is presented in figure, in which the firewall splits the network into three subnets, each dedicated to hosting a particular tier of the application. The firewall is multi homed, which allows administrators to assign a different security policy to each interface.

In this configuration, internet users can directly access only presentation servers, which have access only to middleware servers, which can access only data servers. Juxtapose this design against the architecture of a multitiered application. At the same time, the firewall's rulesbase used to implement access restrictions in this scenario is more complicated than one in which all servers lived ont same subnet. this increases the likelihood that the firewall will be misconfigured, introducing its own risks into this design.

Hosting each tier of an application on a dedicated subnet is a powrful technique because it allows network designers to configure the network in a way that closely matches the application's security requirements, albeit at an added cost of maintaning a more complex firewall rulebase and managing servers located on different subnets. this approach, evident in several design presented in this article, mimics the design of a large ship split into multiple watertight compartments to resist flooding. If one of the sections is compromised, other areas retain a high chance of maintaning their integrity.
Using a single firewall to segment the network is one of the most affordable ways of separating application tiers, but it is now without limitations. A single logical firewall, even if redundant in hardware, present a single point of failure for the design, especilally when it enforces security policy for subnets that host servers of different risk levels. if the firewall is compromised or miconfigured, an intruder could obtain access to all subnets, including the most sensitive segment that hosts data servers. moreover, the firewall may become a performance bottleneck because it needs to examine traffic passing between all subnets. Let's take a look at an alternative design that uses multiple firewalls to eliminate some of these deficiencies.
