Human Bioscience From a study of registered nurses' conceptions of the physical science underlying their clinical practice, it was d that understanding of the physical sciences is inadequate. This inadequacy was in terms of the competencies required of them as nurses (Wilkesand Batts, 1998). The changing patterns of health care delivery have amplified the complexity in all practice environments. As a result, nurses are unable to forecast what activities make a difference in the outcomes and satisfaction levels of their patients. This failure to identify and control the processes, procedures, models, services, and responsibilities related to safe, compassionate care deliverance and better health outcomes does not promise professional practice of nursing. This paper explains with examples the importance of understanding of physical sciences (chemistry and physics) for the nursing practice.
Situation No. 1
Today's operating room is a complex environment. Nurses need to have complete knowledge about all the equipments present in the operation theater. Nurses need to have the basic sense of lighting equipments, the ventilators, the ECG, Laproscopes, etc. only with the basic knowledge of these equipment they can arrange the operation theater and also be prepared for any emergency situation. For an operation to be successful, multiple complex tasks must be carried out, both serially and in parallel, while care is exercised to ensure the safety of the patient. It is vital that the operation room be designed so as to permit patients, operation room personnel, and equipment to move and be moved as necessary without being unduly hindered by overcrowding or by obstruction from cables, wires, tubes, or ceiling-mounted devices. Before and during the operation, critical devices must be positioned so that they can readily be brought into use for monitoring and life support.
Situation No. 2
It is essential for a nurse to have a good knowledge of chemistry. For example in the operation room there are a number of chemicals that may present treat to all individuals in the operation room. Chemical hazards exist from the use of trace anesthetic gases, various detergents used to clean surgical equipments, flammable anesthetic agents and antimicrobial solutions, medicines, and latex products. It is important for the nurse to have complete knowledge of these harmful gases and the steps that need to be taken in case of exposure. Besides there are also other physical hazards such as electrical shock and burns, exposure to radiation from x-ray equipment, and injuries that may be caused by using lasers. In addition to causing injury directly, the use of lasers can expose operation room personnel to papillomavirus in smoke plumes. Here again it is very important to have a complete knowledge to safeguard patients, and all others in the operation room and of course themselves.
Situation No. 3
Chemistry for its part has been an important branch of science with numerous applications in the human arena especially for the nursing practice. If a nurse is equipped with the theory, knowledge and research of Chemistry, life becomes much easier. In fact they can serve the patients much better. If a nurse knows how to prepare various solutions at short notice, this can be tremendous help both for the doctors and patients. The through knowledge of concentration is a must for this. In case when the nurses have to look at the lab reports, it becomes very essential to know the normal range of chemicals that has to be present in the patient. With in increasing complexity of the nursing practice, the through understanding of physical sciences (physics and chemistry) is very essential. These subjects have equally important application in the nursing science as that of the clinical practice.

This paper seeks to address both good and bad factors that have arisen from organ donation.
The body organs that are usually considered for donation include hearts, kidneys, lungs, livers, and the pancreas. Body tissues that are donated include skin, corneas, connective tissues, bone, and blood vessels. According to (Tilney, 2003:137), “the donation of a liver, heart, pancreas, and lungs can only take place if the donor is brain dead. The donation of body tissues like skin, bone, and corneas, on the other hand, can take place in spite of age as well as with any fatal outcome.” In the last decade, there are some factors that have increased the number of organ transplant that have been successfully carried out. These include:<...

...HUMAN BIOSCIENCE Human Bioscience Introduction Maintenance of the pH of the blood is an important process which has to be regulated strictly by the human body. The normal blood pH ranges from 7.35 to 7.45 and deviations from the normal range can lead to hazardous outcomes as the functions of the body are very sensitive to the pH. A blood pH which is below 7.2 has serious consequences such as reduced growth, a decline in cardiac output, resistance to insulin; a lower than normal blood pressure and raised blood potassium levels (hyperkalemia). On the other hand, a pH above 7.6 leads to low calcium in the body causing tetany and abnormalities in the hearth rhythm. pH has a direct effect on the structure of proteins in the human body as pH...

The Humane Elements of Human Euthanasia

 Credibility material: As I watched my grandmother deteriorate into her senility, slowly forgetting everyone she knew as well as the logical explanation for the tremendous pain she suffered as a result of her cancer, it became increasingly important to me to find some way of reducing her pain and suffering. The only available answer, euthanasia, was not available legally, so my grandmother was forced to die a terrible death in confused terror among strangers.

The British Constitution vs The Human Rights Act 1998

This research essay analyses the above statement and arrives at a conclusion.
Integration of the provisions of ECHR into U.K’s domestic law by way of HRA 1998 can be regarded as revolutionary as it facilitates the majority of the ECHR rights provisions directly applicable in the U.K. Before that integration, a U.K Court has to presume that when there is a clash between U.K’s domestic law and ECHR rights provision, the ECHR rights provision will always prevail. This principle has been laid down in R v Secretary of Home Dept ex parte Brind1 and R v Secretary of Home Dept ex parte Thakrar. 2
Courts have now the power to declare any statue which they find incompatible with ECHR provisions and order for fine-tunin...

Issues Connected to Human Resources Management

Notably, management professionals would agree, HRM system is an integration of various management practices with ‘people’ at its prime focus (Jackson, Schuler & Werner, 2008); and, the common factor between business organisations and educational institutions is ‘people,’ although their goals differ. This could be one main reason for attempting to implement HRM in educational institutions, although it is customized to organisational benefit.
