A disaster could be a natural or artificial (or technological) hazard leading to an occurrence of considerable extent inflicting important physical harm or destruction, loss of life, or forceful modification to the atmosphere. A disaster may be extensively outlined as any tragic event stemming from events like earthquakes, floods, harmful accidents, fires, or explosions. Researchers are learning disasters for quite a century, and for quite forty years disaster analysis for the better understanding of the events restricted to disaster science and related areas. Man-made disasters are the consequence of technological or human hazards. Examples embody stampedes, fires, transport oil spills and nuclear radiation. War and deliberate attacks might also be place during this class. Like natural hazards, artificial hazards are events that haven't happened, for example terrorist act. Artificial disasters are samples of specific cases wherever artificial hazards became reality in an occurrence.
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
