Neutral Sitting Posture

The principles of neutral sitting postures for computer operation are as
follows:

(i) Forearms straight and parallel to the floor;

(ii) Hands and wrists straight and should not bend up, down or to the side;

(iii) Shoulders relaxed and not elevated, raised or abducted;

(iv) Elbows bent approximately 90 degrees, close to the body and supported on an arm rest;

(v) Feet must be fully supported on the floor and should not hang;

(vi) Back fully supported on back rest or lumbar support. Should not lead forward and without support; and

(vii) Popliteal should have clearance to promote blood circulation in the leg and there should not be any compression to the popliteal by the seat pan.

Safety Culture and Safety Performance

Let us discuss what makes some companies prone to accidents, while others are accident-free. Numerous studies have been conducted to determine the factors that make a company prone to accidents. There is a growing body of empirical evidence concerning the impact of safety culture on safety performance. Numerous studies have investigated characteristics of companies with low accident rates, while generally comparing them with similar companies with higher-than-average accident rates. A fairly consistent result of these studies conducted in industrialised as well as in developing countries, emphasises the importance of senior managers' safety commitment and leadership for safety performance (Chew 1988; Hunt and Habeck 1993; Shannon et al. 1992; Smith et al. 1978). Moreover, most studies show that in companies with lower accident rates, the personal involvement of top managers in occupational safety is at least as important as their decisions in the structuring of the safety ma

Nuclear Biological and Chemical Terrorism-1

Introduction Terrorism is a criminal act that influences an audience beyond the immediate victim. The strategy of terrorists is to commit acts of violence that draws the attention of the local populace, the government and the world to their cause. The terrorists plan their attack to obtain the greatest publicity, choosing targets that symbolise what they oppose. The effectiveness of the terrorist act lies not in the act itself, but in the public's or government's reaction to the act. Terrorism has become a global threat and needs to be controlled from the root level to the international level. Governments throughout the world are realising that terrorism is a serious threat. The bombing of the World Trade Centre in 2001 was one of the deadliest terrorist episodes in the world. There are various types of terrorism nuclear, biological and chemical (NBC) terrorism. Different types of terrorism have been defined by lawmakers, security professionals and scholars. Types

Hazards of Radio Frequency from Mobile Towers and Phones

Cell phone radiation damages DNA, inflicts cellular damage and creates a broad spectrum of health problems and diseases, including DNA mutation and cancer in humans. A group of scientist published this in a scientific journal “Oxidants and Anti oxidants in Medical Science” in March 2014, in a study called “Low intensity radiofrequency radiation: a new oxidant for living cells”. 76 studies (or 92.5%) proved that cell phone radiation inflicts cellular damage. Cell phone radiation affects production of Reactive Oxygen Species (ROS); these are molecules that form in our bodies as byproduct during normal metabolism of oxygen. A healthy human body has balanced, non health-threatening amounts of ROS. However, microwaves cause overproduction of ROS and dramatically increase oxidative stress – body’s inability to detoxify itself and repair the damage. Too much of ROS damages lipids, proteins and DNA in cells, and disrupts all kinds of natural cellular interacting signals,
