Iqra University‚ Karachi INTRODUCTION Job stress can be defined as the harmful physical and emotional responses that occur when the requirements of the job do not match the capabilities‚ resources‚ or needs of the worker. Job stress can lead to poor health (mental and physical). "25% of employees view their jobs as the number one stressor in their lives." --Northwestern National Life. "75% of employees believe the worker has more on-the-job stress than a generation ago." --Princeton Survey Research

Heat engine lab Intro: when an engine runs‚ it pumps pistons that move up and down and provide energy to the engine to it to go. These pistons move because of pressure and heat. This work done on the system is not only mechanical but its also thermodynamic. When a piston undergoes one full cycle its displacement is zero because it comes back to its resting place. This means that its net thermodynamic work to be done should also be zero‚ as well as its total internal energy. In order to test this

can help to reduce levels of stress? Why or why not? Stress is a negative feeling induced by a wide range of stressors which brings forth changes to our body physically and mentally. Intense and prolonged pressure would make us stressful and lead to the warning signal of our body showing that we are more vulnerable to stress-related disorders such as heart disease and depression (Kemeny‚ 2003). Therefore‚ when human beings encounter stress‚ they would adopt various methods to cope with it trying

SEWAGE TREATMENT Sewage is a mixture of domestic and industrial wastes. It is more than 99% water‚ but the remainder contains some ions‚ suspended solids and harmful bacteria that must be removed before the water is released into the sea. The treatment of wastewater is divided into three phases: pretreatment‚ primary treatment and secondary treatment. Pretreatment Large solids (i.e. those with a diameter of more than 2cm) and grit (heavy solids) are removed by screening. These are disposed of in

was formed. One of the many uses for music therapy is stress management. Throughout the course of a day people experience many stressors‚ school‚ work and family‚ just to name a few. Music has a unique ability to lower levels of anxiety and tension when listened to under the proper conditions. There are many correlations between the types of music listened to and the amount of decreased stress. To explain how some music lowers levels of stress and others don’t‚ one should know how sound is processed

Heat of Neutralization Lab Objective: The objective of this lab was to measure‚ using a calorimeter‚ the energy changes accompanying neutralization reactions. Background: Chemical changes are always accompanied by a change in energy‚ typically as heat. If the reaction releases heat (ΔH < 0) then the reaction is exothermic. If the reaction absorbs heat (ΔH > 0) then the reaction is endothermic. The quantity of heat is measured experimentally by having the reaction take place in an insulated container called a

ABSTRACT The effect of different levels of radiation was determined using four set-ups-10kR‚ 30kR‚ 50 kR‚ and the control (no radiation). The four set-ups were observed for nine weeks and growth (in cm)‚ germination‚ and survival rate was measured. Results showed that at the right level of radiation level (10 kR)‚ radiation have a positive effect on the plant growth and has the same germination and survival rate from the control set up. The 30 kR set up and 50 kR set up are relatively smaller

money and consequently‚ social classes. From 1947 to 1991‚ the Cold War saw the division of the world into two categories‚ eastern communism or western capitalism. Because of the United States’ previous encounters with communism‚ it wasn’t hard for American citizens to support the war against communism. The United States abandoned its isolationist standing to help Western Europe and other struggling nations thwart communist parties. The Cold War resulted in the dissolution of the Soviet Union and the
