There are four major effects of stress associated with the stressed state, viz. emotional, physiological, cognitive, and behavioural.

Emotional Effects : Those who suffer from stress are far more likely to experience mood swings, and show erratic behaviour that may alienate them from family and friends. In some cases this can start a vicious circle of decreasing confidence, leading to more serious emotional problems. Some examples are feelings of anxiety and depression, increased physical tension, increased psychological tension and mood swings. 

Physiological Effects : When the human body is placed under physical or psychological stress, it increases the production of certain hormones, such as adrenaline and cortisol. These hormones produce marked changes in heart rate, blood pressure levels, metabolism and physical activity. Although, this physical reaction will help us to function more effectively when we are under pressure for short periods of time, it can be extremely damaging to the body in the long-term effects. Examples of physiological effects are release of epinephrine and norepinephrine, slowing down of the digestive system, expansion of air passages in the lungs, increased heart rate, and constriction of blood vessels.

Cognitive Effects : If pressures due to stress continue, one may suffer from mental overload. This suffering from high level of stress can rapidly cause individuals to lose their ability to make sound decisions. Faulty decisions made at home, in career, or at workplace may lead to arguments, failure, financial loss or even loss of job. Cognitive effects of stress are poor concentration, and reduced shortterm memory capacity.

Behavioural Effects : Stress affects our behaviour in the form of eating less nutritional food, increasing intake of stimulants such as caffeine, excessive consumption of cigarettes, alcohol and other drugs such as tranquillisers etc. Tranquillisers can be addictive and have side effects such as loss of concentration, poor coordination, and dizziness. Some of the typical behavioural effects of stress seen are disrupted sleep patterns, increased absenteeism, and reduced work performance.

Gauss’s Law

According to Gauss’s law, the total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The total electric flux through a closed surface is zero if no charge is enclosed by the surface.

• Gauss’s law is true for any closed surface, no matter what its shape or size.
• The term q on the right side of Gauss’s lawincludes the sum of all charges enclosed by the surface. The charges may be located anywhere inside the surface.
• In the situation when the surface is so chosen that there are some charges inside and some outside, the electric field [whose flux appears on the left side of Eq. (1.31)] is due to all the charges, both inside and outside S. The term q on the right side of Gauss’s law, however, represents only the total charge inside S.
• The surface that we choose for the application of Gauss’s law is called the Gaussian surface. The Gaussian surface can pass through a continuous charge distribution.
• Gauss’s law is useful for the calculation of the electrostatic field for a symmetric system.
• Gauss’s law is based on the inverse square dependence on distance contained in the Coulomb’s law. Any violation of Gauss’s law will indicate departure from the inverse square law.

It was in the Lahore session of 1929 when the president of Congress party-Nehru declared 26th January ,1930 as the date when India will get complete freedom or "Purna Swaraj".It was decided that 26th January would be celebrated as Independence Day,but unfortunately we got our actual freedom on 15th august,1947.Hence this session was of great importance in India's history of freedom struggle.

The Salt March was notable for at least three reasons.

First, it was this event that first brought Mahatma Gandhi to world attention. The march was widely covered by the European and American press.

Second, it was the first nationalist activity in which women participated in large numbers. The socialist activist Kamaladevi Chattopadhyay had persuaded Gandhiji not to restrict the protests to men alone. Kamaladevi was herself one of numerous women who courted arrest by breaking the salt or liquor laws.

Third, and perhaps most significant, it was the Salt March which forced upon the British the realisation that their Raj would not last forever, and that they would have to devolve some power to the Indians.

potassium sulphate

Urea and glucose do not dissociate in solution. Sodium chloride gives two ions and potassium sulphate gives three ions per formula unit.
Therefore, the effective number of particles is maximum in potassium sulphate , and it shows the maximum depression in freezing point.

The coleorhiza is a protective sheath that envelops the radicle in certain plants that is penetrated by the root in germination. It helps in protecting the radicle.

“Management is the process by which a co-operative group directs actions of others toward common goals.” Management is defined as the process of planning, organising and controlling an organisation's operations in order to achieve the target efficiently and effectively. It is essential for all organisations.
