Introduction

There are numerous descriptions of drowning that are available and actually, all of them bear some weight. According to Lunette, G., et.al death by drowning is the consequence of a obstruction of respiration by impediment of mouth and nose by a liquid medium which is more often than not water (2004). Actually, there are many other drowning definitions wherein all have some accuracy. In regards to true drowning, there are relatively no considerable disagreements, since there is a general conduit, which involves the water inhalation, which could eventually pass through the alveolo-capillary membrane thus eventually reaching the general circulation ultimately. Characteristically, a difference ...

Introduction:

Clean non-polluted water is a major basic requirement for all the living things. Nowadays, its availability becomes a major problem in the ecosystem. This problem is expected to increase in the future due to population growth and industrialization processes. The processes discharge of domestic, industrial and agricultural wastes contribute largely to the contamination of existing natural waters in the environment. Therefore, at the present moment, it is important that the pathogens and pollutants are completely removed from the waste water to cater for the needs of domestic use, industrial use, and irrigation purposes. This paper discusses two processes of oxidation and ...

Abstract

Herbivores exclusively feed on plants while carnivores feed on meat. These food preferences mean that there are differences in the oral cavities, the stomach, the small intestines and the entire digestive tract mechanisms of the two types of animals. While carnivores such as lions have short digestive tracts with stronger and more acidic digestive juices because meat is easier to digest, herbivores such as zebras have long digestive tracts that are alkaline to increase the rate of digestion and absorption of plant materials.
The basic difference between carnivores and herbivores is that they exclusively feed on meat and plants ...

Introduction

Dietary fiber is a combined term for a diversity of plant matters that are resistant to digestion by human gastrointestinal enzymes. Dietary fibers can be categorized into two major groups according to their solubility in water. In humans, natural gel-forming fibers (gums, pectins, mucilage, and the remains of the hemicelluloses) are soluble. Whereas the matrix fibers or the structural (lignins, some hemicelluloses, and cellulose,) are insoluble, Dietary fiber and whole grains are among the best sources of nutrients including minerals, a slowly digestive energy and vitamins. (Byrne, 2011). They also contain phytochemicals such as carotenoids, lignans, inulin, beta-glucan and phenolic. These chemicals ...
