Caffeine is the most pervasively used psychoactive and widely used mood-altering drug in the world. The fact that caffeine is not regulated implies, this drug does not have severe effects. It is clear that the coffee, tea and other beverages that contain caffeine result in addictions.

The addiction arises from its ability to induce sleep, decrease pain, and fatigue, boost memory, and promote anxiety. Caffeine helps in sustaining duration, maximizes effort, and increases speed during endurance events. It has not been ...

The science of sleep cannot boast of its significant age. In essence, the research of the brainwork by scientists continues only the last hundred years. Have you ever tried to do without sleep for a week or a month? Clearly, it is almost impossible. After some time, our brain is tired. The body starts to ache. People without sleep become irritable, lose the ability to think clearly and cannot concentrate. They need sleep - time to recuperate and stockpile for the next activity.
People over 20 years out of 60 spends in a dream, and that is one third of all ...

Investigating how light intensity will affect the rate of photosynthesis, with the help of DCPIP, in Spinach leaves.

The aim of this experiment is to find out how the rate of change of light intensity affect the photosynthesis in spinach leaves.
Successful farming of food crops is very essential for both the nutritional and financial health of a nation. Governments of almost every nation invest land and labour to crop farming, as much as is possible, keeping in mind the other needs of a country. But, however, due to many reasons the maximum crop yield possible is not always achieved.
For the production of a healthy crop certain conditions are necessary. The primary among these conditions are ...

Influence of Coffee on Exercise

Caffeine is a pharmacologically active substance that is consumed extensively around the world today. Various dietary sources of caffeine include coffee, tea, chocolate, carbonated drinks and energy beverages (Goldstein et al., “International society” 2010). Among these dietary sources, coffee is the most significant and widely consumed source of caffeine around the world in the present times. Statistics from North America and Europe show that around 90% of the adults consider themselves as regular coffee drinkers and their average caffeine intake adds up to approximately 200mg per day (Pesta et al., 2013).
Chemically, caffeine is 1, 3, 7,-trimethylxanthine i.e. ...

In numerous ways, the human body can be regarded as chemical dispensation plant. In that, chemicals are ingested, processed via a variety of types of reactions, and then dispensed all over the body to be utilized instantaneously or accumulated for later utility. These chemicals utilized by the body can be separated into two wide groups: the macronutrients, those that we require frequently and in great quantities, and micronutrients, those that we require merely in small amounts. Among the macronutrients, there are three major classes necessary to living organisms: carbohydrates, fats, and proteins.

Introduction
Almost 90% of adults in the United States consume caffeine on a daily basis (Tasman, Kay, Lieberman, First, & Maj, 2011). Caffeine is the most popular mood-altering drug in the world (Tasman et al., 2011). Those who regularly consume caffeine typically drink coffee, tea, sodas or energy drinks as part of their routine. Many Americans depend on regular doses of trimethylxanthine(Nikić, Andrić, Stojimirović, Trbojevic-Stanković, & Bukumirić, 2014), the chemical name for a bitter white powder known as caffeine, to remain alert and fight off exhaustion to be productive throughout the day. Whether it's brewed from a K-Cup, sipped ...

Abstract—In this experiment, a hand dynamometer was used to measure the grip strength of a subject. The forearm muscles were engaged in an activity, and the grip recorded. The electromyogram (EMG) activity was related to the grip strength by making a graph of the maximum grip strength against area under the EMG activity’s absolute integral during the contraction of muscle. Data was recorded from the dominant and non-dominant forearms of the subject and the electrical activity of each forearm compared to its diameter. Prolonged grip strength was also recordings and forearm EMG activity made to determine fatigue rate in both ...

Introduction

Platelets comprise of a very important component in the blood. They prevent blood loss in the body. This is enhanced by formation of an entangled mesh made of fibrinogen which is activated by calcium ions and the von Willbrand factor. A complex physiology ensues within the first few minutes of exposure of the tissue underlying the epithelial tissue in the skin (Hoffman 2009, p.123). Platelets also play a very important role in ensuring the pathogenic organisms are prevented from entering the body through the exposed tissue on the skin. This paper comprise of various components which are intended to illustrate the ...
