nostrils. The mucosa lining the nasal cavity‚ called the respiratory mucosa‚ warms the air as it flows pa Respiratory physiology The major function of the respiratory system is to supply the body with oxygen and to dispose of carbon dioxide. To do this‚ at least four distinct events‚ collectively called respiration‚ must occur: 1. Pulmonary ventilation Air must move into and out of the lungs so that the gases in the air sacs (alveoli) of the lungs are continuously changed and

Distributed File System Abstract A method of storing and accessing files based in a Client/Server Architecture. In a distributed file system‚ one or more central servers store files that can be accessed‚ with proper authorization rights‚ by any number of remote clients in the network. Much like an operating system organizes files in a hierarchical file management system‚ the distributed system uses a uniform naming convention and a mapping scheme to keep track of where files are located. When

This paper is by Anupam Basu The term ‘failure’ here will be discussed in the context of replacement decisions. There are two types of failure: (1) Gradual failure‚ and (2) Sudden failure. Gradual Failure Gradual failure is progressive in nature. That is‚ as the life of an item increases‚ its operational efficiency also deteriorates resulting in Increased running (maintenance and operating) costs. Decrease in its productivity. Decrease in the resale or salvage value. Mechanical

Genetic Variation are the differences within individuals in a population. They are what make us genetically different from one another. Genetic variation occur because of mutations in our DNA and recombination. There are multiple types of mutation such as point mutations or chromosome mutations. Point mutations are the most common where only a single DNA nucleotide is affected. Within point mutations are frameshift and substitution. Frameshift mutations are when a base is either added or deleted
