year 2005‚ thus we can know that accidents rate in Malaysia is actually increasing with a scary speed (Chua‚ 2006). Although road accidents in Malaysia have escalated in the past few years‚ it is still unsure as to who is to be blamed for this increasing rate of accidents. When the accident rate is increasing‚ many people tend to blame the government‚ but actually‚ beside government‚ there are also other factors that partly responsible for the increasing rate of accidents in Malaysia. The purpose

Practical: The Effect of Concentration on Reaction Rate Aim: To use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Independent Variable: Concentration of hydrochloric acid (%) Dependent Variable: Time taken for chemical reaction to take place (sec) Hypothesis: My prediction is that the increased concentration of the thiosulfate will in turn lead to an increase in the rate of reaction. This

INCREASING CRIMES/SUICIDES AMONG THE YOUTH OF INDIA. INCREASING CRIME RATES AMONG THE YOUTH IN INDIA. Introduction: Open any newspaper or tune into any news channel and you can be pretty sure to stumble upon crimes of all sorts ranging from petty thefts to dacoity‚ murder‚ terrorism‚ sexual crimes and the like. The statistics show that the miscreants have been found quite focused and determined at their jobs. In India for instance‚ as per the National Crime Records Bureau‚ incidences of crime

Aim:The aim of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise‚ we measure the breathing rate before physical activity by counting the number of breaths

THE EFFECTS OF EXCHANGE RATE IN INFLATION OUTPUT AND THE CURRENT ACCOUNT ABSTRACT The empirical studies on the effects of changes in exchange rates on inflation and real activity can be broadly divided into four categories: Single-equation econometric methods‚ Vector autoregressive (VAR) models‚ Structural macro econometric models and DSGE models - Dynamic stochastic general equilibrium. Methodologies: First‚ most participants use single-equation econometric methods that estimate

Assessing Blood Pressure Anatomy of the Heart The heart is located in the thoracic cavity between the lungs within the mediastinum. It is a hollow‚ cone-shaped‚ muscular organ about the size of a fist. Functions of the Heart keeps O2-poor blood separate from O2-rich blood; keeps the blood flowing in one direction—blood flows away from and then back to the heart in each circuit; creates blood pressure‚ which moves the blood through the circuits; Regulates the blood supply based on

THE EFFECTS OF COLD ON BLOOD PRESSURE AND PULSE Abstract The ability known as thermoregulation is a feature of an organism that help to keep the body temperature within certain thresholds‚ thus independently from external conditions. A dynamic state of thermal balance of human body between its internal environment and the territory is a model example of precise control of organism heat. In the case where such stability would be disturbed the immediate response would appear as well. In accordance
