Bhagat Singh : True Face of FEARLESSNESS

Bhagat Singh was a prominent freedom fighter of India. The courage with which Bhagat Singh fought the mighty British government for the independence of the country is a great role model for the youth of today. He also refused to run away by throwing a bomb in the Central Parliament (Central Assembly). As a result of which he was hanged on 23 March 1931 along with his two other companions, Rajguru and Sukhdev. The whole country remembered his sacrifice very seriously. First the Saunders-Slaughter in Lahore and then the Explosion of the Central Assembly in Delhi with Chandrashekhar Azad and other members of the Party gave rise to an open rebellion against the British Empire. Bhagat Singh was interested in anarchist and Marxist ideology. Early Life: Bhagat Singh was born on 27 September 1907. His father's name was Sardar Kishan Singh and mother's name was Vidyavati Kaur. It was a Sikh family. The Jallianwala Bagh massacre that took place in Amritsar on April 13, 1919 had a profoun

BIO GEO CHEMICAL CYCLE

 

 BIO GEO CHEMICAL CYCLE

We live in the environment where there are both biotic and abiotic components. Abiotic components are the air, water, light and temperature. Biotic is the living components which include human beings. This kind of ecological complex is called as the ecosystem. It deals with the relationships between the organisms and ecology. Thus, the interaction is both dependent on the ecology.


WATER CYCLE

Water is the important source of all living beings. Oceans are the biggest storehouses of water as they evaporate for the formation of clouds. The evaporation process is also due by rivers, lakes and ponds. Condensation is a process in which the watervapour converts to rain. Now the rain water flows and fills all the water resources. 

A huge amount of water is recycled directly without the involvement of biotic components. The sun's heat and wind movement help to evaporate water from the exposed surface of the oceans. So, the rivers and lakes act as a reservoir here, which finally collects water to the oceans.


NITROGEN CYCLE

Living organism requires both proteins and nucleic acids for their survival. The atmosphere consists of 78 percent of ammonia and plants and animals can only use in the form of ammonia, nitrates or amino acids. This conversion is called the nitrogen cycle. 

The steps involve Nitrogen fixation, assimilation, Ammonification, Nitrification and Denitrification.

Nitrogen fixation is done by Nitrogen fixing bacteria and algae that converts ammonia into nitrates. Nitrogen Assimilation is done by Nitrates that are absorbed by plants are utilized for making organic matter such as proteins and nucleic acids. The process of urea, uric acid, which is released by amines and ammonia is released by the action of bacteria or fungi and it is called ammonification. Ammonia is then converted to nitrites, it is called as Nitrification and then denitrification occurs by reducing nitrate ions into gaseous nitrogen which returns to the atmosphere.


CARBON CYCLE

All living organisms are made up of carbon. The atmospheric carbon dioxide enters into the living world followed by photosynthesis and the carbon is passed. Carbon dioxide is returned back to the atmosphere through the decomposition of dead organic materials and volcanic activities.


OXYGEN CYCLE

Oxygen is important for respiration which contributes 20% of the air in the atmosphere. Enters into the living world through respiration and produces energy. 


Now-a-days we get climatic changes quickly due to the change in one of these cycles. Burning fossil fuels, using limestone for making concrete and more things. If any one of the cycle is disrupted it would be really difficult for the humans. It is purely our responsibility to save the nature!

Doctrine of Notional Extension under the Workmen Compensation Act, 1923

  There is no problem in detecting that the accident occurred in the course of employment when a workman is injured in the working place and in the working hour and doing his duty. The problem arises when these elements do not coincide together. But a workmen if injured just near the work premises or just before joining the work or in the way to work problem arises. To address this kind of problem and giving some kind of relief to the workmen the theory of notional extension evolved. “As a rule, the employment of a workman does not commence until he has reached the place of employment and does not continue when he has left the place of employment, the journey to and from the place of employment being excluded. It is now well-settled, however, that this is subject to the theory of notional extension of the employer’s premises so as to include an area which the workman passes and repasses in going to and in leaving the actual place of work. There may be some reasonable extension in bot

Peace - A Way Of Life

To be peaceful is the sign of a conqueror.  We have often heard people saying 'follow the path of peace and you will be happy', 'preach peace' and many other phrases emphasising on a way of living- Peace. But what is it really about?  With reference of the holy Bible, peace is defined with notions like  totality or completeness, success, fulfillment, wholeness, harmony, security and well being.  The definition of peace changes with mindsets of people. For one, it is a sense of accomplishment, non- violence for another, salvation to a few and a lot more to others. But what peace exactly is? And how can we attain it? Peace is acceptance. A vision of seeing things and extracting optimism out of it. Peace makes life easier. To be satisfied is what peace is. To be able to look back at your life and accept all its darks and jewels is what peace feels like. Peace is a state of mind where your soul feels calm, free from the dirt of hatred, negativity, criticism, inferiority and
