Science & Technology Current Affairs February 4th Week 2016

1) ISRO successfully test cryogenic engine of GSLV Mark 3 rocket.

  • Indian Space Research Organisation’s (ISRO) bid to acquire the capability to launch heavier satellites into orbit received a boost with the successful hotbed test of the cryogenic engine for the upper stage of the GSLV Mark 3 rocket.
  • The long-duration test at the ISRO Propulsion Research Centre at Mahendragiri ,Tamilnadu lasted 640 seconds.
  • It was conducted with Mixture Ratio Controller (MRC) in a closed loop mode.
  • The CE20 uses Liquid Hydrogen at - 253 degrees C and Liquid Oxygen at - 193 degrees C as propellants and generates power of approximately 2 MW.
  • Developed at the Liquid Propulsion System centre (LPSC), the engine had already undergone two short-duration tests for engine ignition and steady state performance.

2) Facebook Telecom Infra Project launched to help boost internet connectivity.

  • Facebook has announced a new Telecom Infra Project as part of its overall Internet.org mission.
  • The Telecom Infra Project(TIP), which will look at developing new and alternative technologies to build and deploy telecom infrastructure, with partners including Aricent, HCL Technologies, Intel, Nokia and T- Mobile.
  • The Project is working on providing currently unserved rural communities with wireless network efforts.
  • A pilot 4G network is already underway in the Philippines, and Facebook has a project in planning for the Scottish Highlands.
  • TIP will focus on open designs for three areas of telecommunications hardware and software access points, the backhaul network to connect them, and network core and management systems.
  • The new technologies developed and tested with different partners of the TIP project will be shared with the rest of the community. 

3) US Air Force Test-Launches Minuteman Missile From California.

4) NASA working on crunching a Mars trip to three days.

  • NASA researchers are working on a technology that could harness the power of light and may be the key to cutting down travel time to Mars from months to as little as three days.
  • Philip Lubin, from the University of California, Santa Barbara, is developing the ‘photonic propulsion’ system where lasers can propel spacecraft with giant sails to the Red Planet.
  • The system relies on the momentum of photons - particles of light - to move forward. However, instead of photons from the Sun’s rays.
  • Prof. Lubin’s design would be given a push by giant Earth-based lasers.
  • The current technology, it is estimated it will take humans around five months to reach Mars. 

5) CGPDTM issues revised patent guidelines for Computer Related Inventions.

  • Controller General of Patents, Designs and Trademarks (CGPDT) has issued an order excluding software patents in its revised guidelines for Computer Related Inventions (CRIs).
  • The new order clearly mentions that, mere computer programmes those not in conjunction with a novel hardware will not be granted patent in India.
  • CGPDT’s stay on the revised guidelines issued in 2015 which have allowed the patenting of software which demonstrated technical advancement and did not clarify it.
  • CGPDTM had agreed with a Parliamentary Panel which had observed that computer programmes as such are not intended to be granted patent as per Patents Act, 1970.
  • The sub-section 3(k) of Act mentions that mathematical methods or business methods or computer programme or algorithms are not patentable.

  • The (RMAb), has been developed by Pune-based Serum Institute of India (SII) and US-based Mass Biologics of the University of Massachusetts Medical School.
  • RMAb drug is a human IgG1 monoclonal antibody that instantly deactivates rabies virus by specifically binding to a conformational epitope of G glycoprotein of the virus.
  • It is 25% cheaper compared to the existing expensive human rabies immunoglobulin (hRIG) treatment.
  • It has advantage of automatically precluding the chances of transmitting blood-borne infections that are present in rabies immunoglobulin vaccines.
  • The drug has been manufactured using recombinant DNA technology that includes inserting DNA encoding antigen (such as a bacterial surface protein) to the microbial DNA of cells in the body to stimulate immune response.
 
8) India`s first nuke submarine INS Arihant passes deep sea tests.
  • India’s first indigenously built nuclear armed submarine INS Arihant has successfully passed several deep sea diving drills as well as weapons launch tests.

  • The move to set up additional radar assumes significance as it will help authorities in taking timely action against cyclones prone to the eastern coast and also help better forecast.
About Doppler radar:
  1. It is an observational tool for monitoring and predicting severe weather events such as hailstorms, thunder storms, cyclones and tornados within a radius of 300 km.
  2. It uses the Doppler effect by bouncing a microwave signal off a desired target to produce velocity data.
  3. This data inturn helps in analyzing object’s motion by altered the frequency of the returned signal.
