ocean currents and their impacts on marine life and coastal environment

Image
Its physical characteristics like temperature, salinity, density and the external forces like the sun, the moon and the winds influence the movement of ocean water. Ocean currents are the continuous flow of huge amount of water in a definite direction. Water moves ahead from one place to another place through ocean currents. Ocean currents have direct impact on the climate and economy of the region.  Ocean currents and water masses differ in their impacts on marine life and the coastal environment in different ways:  • Impact on biodiversity:  The physical parameters of water masses are essential because they structure the water masses and determine the various habitats that provide the environmental conditions required for marine life.  These conditions influence the production and the growth of plankton and fish species. The dispersion and dwelling of larvae for many benthic and pelagic species depend on hydro-graphical factors. They also play an important role for...

INSAT-4CR Satellite, ISRO

Image
GSLV-F04 is the fifth flight of India's Geosynchronous Satellite launch Vehicle (GSLV), launched INSAT-4CR satellite, into a Geosynchronous Transfer Orbit (GTO) of 170 km perigee and 35,975 km apogee with an orbital inclination of 21.7 degree with respect to equator on September 2, 2007. Subsequently, the satellite was manoeuvred into geostationary orbit using its own propulsion system. The 49 m tall GSLV, with a lift-off mass of 415 tonne, is a three-stage vehicle with solid, liquid and cryogenic stages. The first stage of GSLV, one of the largest in the world, uses Hydroxyl Terminated Polybutadiene (HTPB) based propellant. The second stage and the four strap-on motors surrounding the first stage use liquid propellant 'Vikas' engine burning UH25 and Nitrogen Tetraoxide. The third stage is a cryogenic stage using liquid Hydrogen as fuel and liquid Oxygen as oxidiser. GSLV employs S-band telemetry and C-band transponders for enabling vehicle performance monitoring, tracking,...

CARTOSAT – 2A, ISRO Satellite

Image
  PSLV-C9 is the thirteenth flight of ISRO's Polar Satellite Launch Vehicle (PSLV) and the third flight of its 'Core Alone' version as well. In this flight, PSLV launched ten payloads - India's 690 kg CARTOSAT-2A and 83 kg Indian Mini Satellite (IMS-1) as well as eight nanosatellites from abroad together weighing about 50 kg into a 635 km high polar Sun Synchronous Orbit (SSO) inclined at an angle of 97.94 deg to the equator.   With much lighter payloads compared to the ones placed into orbit by its standard version, PSLV-C9 is configured without the six solid propellant strap-on motors of the first stage. The previous two launches of PSLV were also such 'Core Alone' versions. The Core Alone PSLV-C9 had a lift-off mass of 230 tonne.     PSLV has emerged as the workhorse launch vehicle of ISRO with eleven consecutively successful flights so far. Since its first successful launch in 1994, PSLV has launched eight Indian remote sensing satellites, HAMSAT - an amateu...

Values and Ethics

Values are the individual principle or beliefs that guide judgement and behavior of a person or a group. Values are like an anchor in a ship. Values flow from the highest of our own self which are in inbuilt mechanism which distinguish the right from the wrong, the Do’s and Don’ts of any action even when no one is looking.  The word ethics has been derived from the Greek word ‘ethos’ meaning ‘character’. Ethics is a branch of philosophy that refers to a study of rightness or wrongness of human action in the context of a good human life. Professional competence is always evaluated within the boundary of ethics and norms associated with the profession.  A person can be professionally competent and expert but if the practices certain immoral acts, it will be refereed as unethical which will in turn hamper the transparency, efficiency, effectiveness, public trust etc. And thus these unethical conducts will erode the roots of the profession itself, harming the stakeholders.

The bill for reservation women is still pending in the parliament.  • Economic participation: Women are not able to reach the topmost positions in the corporations, private or public except a few. Also, women are imparted roles which are regarded as specifically for women like Pink color Jobs, Health sector, etc.  • Education: They are still considered as burden in the villages of many states, though the situation has ...
