Concept of Weight - Essay Example Weight can be described and defined in a physical as well as social context. It is referred to as mass in law, in colloquial uses and in commerce. However, I would wish to describe and define it on a medical perspective. Weight is one of the most important issues as far as quality health care is concerned. It can be defined as the body mass index of an individual, or the heaviness of an object, or simply mass. It is a very essential issue when examining health matters on individuals because it is known medically to be a major contributor and cause of various conditions. The health of any individually changes significantly by change of BMI. The weight of a person keeps increasing, if little concern is considered, to a point where their lives start changing for the worse. Too much weight is capable of causing illnesses, which would never have been encountered had the weight been checked constantly. Weight, therefore, plays a big role in the health-care sector and is always recommended as one of the weapons used in health-care to assist clients maintain a healthy body. According to medical experts, including nurses and doctors, it is advisable to always keep low BMI’s so that even when sicknesses strike, it is easier to treat and get rid of them. A high body mass is dangerous to an individuals health (Alters & Schiff, 2011). As a medication caution, the first test for persons in hospitals is weight checking. These weights are used to determine whether the patient’s body mass is capable of posing danger to their health and whether it is the reason for the condition of the patient if sick. There are various ways used by the health-care providers to assist patients and clients to maintain or change their body weight. Hospitals and other health-care institutions encourage safe body mass and weight, and they provide ways of managing it. Health-care sector is commonly

Petroleum extraction process - Term Paper Example However, to start drilling the reservoir containing the sufficient amount of oil should be found. The researches on oilfield exploration started in 19th century. They were aimed on studying features of bedrocks. The main purpose was to find the rocks that were suitable rock as reservoir of oil (Speight 100). In the beginning of the 20th century surface rock with suitable characteristics were studied. New techniques developed in 1960s provided the possibility of exploration below the surface of earth (Speight 101). New geophysical technologies are based on studying gravitational, magnetic, seismic, electric, electromagnetic and radioactive properties of the bedrocks. The methods are subdivided on techniques without depth control and techniques with depth control. The first group utilize spontaneous responses from local and distant sources that are controlled by the observer. The second group foresees introduction of energy (electric or seismic) into the ground, analyze and interpretation of transmissibility (Speight 101). Gravitational methods are connected with studies of gravitational field which is affected by differences in density of geological bodies. Therefore, the gravimeter detects differences in density, and the detected variations permit to make a conclusion about the presence of rock formations (particularly oil). Magnetic methods are based on detection of the magnetic properties of the rocks. Detected difference provide the possibility to suggest the presence of desired materials. Seismic methods are based on creation artificial shock and detection the time necessary for the vibration impulse to get to the seismic detector. Depending on the obtained results, the conclusion about presence of oil can be made. Electric and radioactive methods are based on the measurement of conductivity and radioactivity (respectively) of the studied
