The person who signs the issue voucher takes responsibility for the care of the apparatus or equipment order assurans 20mg amex mens health flat stomach. Duplicate copies are given to the department (section) that receives the equipment. Controlling and Maintaining Equipment Expendable equipment needs to be controlled to avoid wastage. Convince staff: There is no easy way to convince staff of the need to clean equipment and keep it in good condition. The best way is for the supervisor (manager) to set a good example and to emphasize that equipment must be cared for: To prevent transmission of infection. Inspection Checklist Equipment in a department is inspected by seeing what is present and checking it against the inventory. How often equipment should be checked depends on whether it is consumable or long lasting and whether it is liable to bark down. Explain how to order, issue, store, and control laboratory chemicals and equipment. The need and importance of laboratory safety should be the real concern of the laboratory. Laboratory accidents and hazards are controlled by the use of: Simple precautions Foresight (prudence) Safety devices Above all a ‘real concern’ or a ‘built in concern’ or ‘safety mindedness’ for oneself and the other fellow working at the next bench is very essential. These include: Poorly designed laboratory Over crowding of materials Poor training Lack of concentration Noisy and untidy working environment Carelessness and neglect Overwork and fatigue Hot and humid climatic conditions Hurrying to finish work on time Emergency condition (especially during night hours) 7. Poorly Designed Laboratory Buildings Due attention should be given in the design of laboratories. The management, the laboratory personnel and the architecture should be involved in the standard design of the 83 Health Laboratory Management and Quality Assurance lab, (for more information, see chapter 3 under safe lab design). Burns Burns may be caused by: Flammable chemicals and stains, or by reagents catching alight. Spirit burners should not be used in direct sunlight because in bright light the flame can be difficult to see. Toxic harmful chemicals Inhaling fumes from toxic chemicals Ingesting toxic chemicals by mouth pipetting Skin contact B. Explosive chemicals Injury from explosions can be caused by: Incompatible chemical exploding Leaking gas C. Corrosive (strong acids & alkalis) Concentrated sulphuric acid Nitric acid Sodium hydroxide Potassium Hydroxide b.

This is an overview independent of the social cheap 20 mg assurans fast delivery prostate cancer causes, legal, economic and logistic issues of providing workers with access to food. Some readers may wish to skip this chapter and move on to the framework and case study chapters. We have provided a more extensive review of nutrition in appendices A and B to augment this chapter because, while the topic is important, we did not want to interrupt the flow of the publication with detailed nutrition information. The appendices expand on the notion of nutrient absorption, how certain diseases limit absorption, and how certain nutrients complement or conflict with each other. To reach as broad an audience as possible, a variety of foods are listed here and in the appendices as sources for specific nutrients. For example, beef, pork, lamb, goat, fowl and fish are all legitimate sources of high-quality protein; and vegetables, including soya beans, in the right combination can supply protein needs. Our planet provides a sizeable menu from which we can choose; and most traditional diets – barring restrictions due to war, famine or religious obligations – satisfy and often exceed the nutritional requirements of most individuals. Energy that is consumed as food and not used by the body will be stored and 25 Food at work: Workplace solutions for malnutrition, obesity and chronic diseases result in weight gain. Inadequate intake of food to meet energy requirements will result in weight loss and often the breakdown of body tissue. In both scenarios – obesity or undernourishment – the result is a decreased ability to work and to resist disease. Undernourishment, or insufficient dietary intake, plagues developing nations and stunts productivity. This is a result of either low iron (Haas and Brownlie, 2001), low amounts of other nutrients, or too few calories. Poorer nations are most likely to rely on manual labour, and workers there are mostly likely to be underfed. One study has shown that some cutters and stackers in South African sugar-cane fields lose 3 per cent of their body mass as a result of high energy expenditure and inadequate calorie intake (Lambert, Cheevers and Coopoo, 1994). Protein energy malnutrition is the main nutritional disorder associated with a diet poor in quality and quantity. Obesity is a growing concern in most developed countries and in many developing countries, as energy-dense foods, coupled with automation, serve to promote weight gain. Proper utilization of energy in terms of calories consumed and spent must be the foundation of any nutrition programme. Energy requirements and energy content in food are measured in calories or joules.
We begin with a general framework for thinking about the ethics of scientifc research in psychology buy cheap assurans 20 mg on line prostate 89. Then we look at some specifc ethical codes for biomedical and behavioral researchers—focusing on the Ethics Code of the American Psychological Association. Finally, we consider some practical tips for conducting ethical research in psychology. Describe a simple framework for thinking about ethical issues in psychological research. Give examples of several ethical issues that arise in psychological research—including ones that affect research participants, the scientific community, and society more generally. Ethics is the branch of philosophy that is concerned with morality—what it means to behave morally and how people can achieve that goal. It can also refer to a set of principles and practices that provide moral guidance in a particular feld. There is an ethics of business, medicine, teaching, and of course, scientifc research. As the opening example illustrates, many kinds of ethical issues can arise in scientifc 1. For this reason, it is useful to begin with a general framework for thinking through these issues. The idea is that a thorough consideration of the ethics of any research project must take into account how each of the four moral principles applies to each of the three groups of people. Scientific Moralprinciple Researchparticipants Society community Weighing risks against benefits Acting responsibly and with integrity Seeking justice Respecting people’s rights and dignity Table 3. Let us look more closely at each of the moral principles and how they can be applied to each of the three groups. Scientifc research in psychology can be ethical only if its risks are outweighed by its benefts. Among the risks to research participants are that a treatment might fail to help or even be harmful, a procedure might result in physical or psychological harm, and their right to privacy might be violated. Among the potential benefts are receiving a helpful treatment, learning about psychology, experiencing the satisfaction of contributing to scientifc knowledge, and receiving money or course credit for participating. Scientifc research can have risks and benefts to the scientifc 2 community and to society too (Rosenthal, 1994). A risk to science is that if a research question is uninteresting or a study is poorly designed, then the time, money, and efort spent on that research could have been spent on more productive research. A risk to society is that research results could be misunderstood or misapplied with harmful consequences. Of course, the benefts of scientifc research to science and society are that it advances scientifc knowledge and can contribute to the welfare of society. It is not necessarily easy to weigh the risks of research against its benefts because the risks and benefts may not be directly comparable. For example, it is common for the risks of a study to be primarily to the research participants but the benefts primarily for science or society.
Ifgeneia Riga (2012) a linear building process purchase assurans 20 mg overnight delivery mens health xp, design and constructon methods are studied through a taken into consideraton. Thus, a holistc design efectvely addressing environmental of materials and resources whose demand contnues to grow but availability is technical research and a research by design in order to understand the framework issues by closing the materials cycle is not approached, therefore causing the building becoming scarcer. The building industry most commonly and set the related strategies of a Closed Material Cycles architectural design. Engels A Closed Material Cycles design approach where materials remain in productve use the puzzle to be solved deals with three main challenges related to an architectural be used and fnally exit as waste. A linear design approach in architecture can lead afer their service lifespan as technical and/or biological nutrients is the technical design: to design solutons of systems which seldom comply with possibilites for perpetual Ir. Groenewold-Stengs topic, which gives specifc directons and outputs for the conducton of a hotel reusability and recyclability, not efectvely addressing the scarcity problem. Design frameworks aiming to setng Closed Material Cycles strategies and whole, are not viewed in a way that allows for a thorough plan of Background info: methodologies are examined as a frst stepping stone towards an architecture Closed Materials Cycle to be approached. Motivation which efectvely addresses environmental issues caused by the misuse of materials Having earned my Diploma as an Architect Engineer, I contnued to my Master through the design practce. Materials misuse in the context of highly consumerist further insight into the essental aspect of architectural “how”, studied by the strategies which allow for the recollecton of materials, the selecton of materials negatve impact on human and environmental health. My research interests under this scope and processes which have positve efects on humans and environmental health, and of extracted materials is used for emerging constructons, in an open product the selecton of materials and processes which allow for their perpetual reutlisaton → Materials and processes currently used for the realisaton of a building, design system. In the current architectural practce building sub-systems and their lied in studies related to environmental issues; existng and arising challenges of as technical or biological nutrients. However, dynamic approaches which would and “answered” by building technologies as a way towards the realizaton of an also include waste management, toxicity avoidance, recyclability and reutlisaton environmentally conscious architectural approach. The concept of closed life cycle material fows in architecture can provide a more holistc approach to the materials scarcity and Startng in November 2011 when the proposed research topic of Closing the related environmental occurring issues. By applying such strategies, one can talk University: Delf University of Technology, the Netherlands Materials Cycles was defned, by January 2012 the preliminary research had formed about a “viable” architecture, expanding the meaning of sustainability. Similarly, for the research by design part of the identfcaton of materials and processes which allow for the perpetual re-utlisaton thesis, these three conditons altogether acted as architectural criteria, exceeding of materials as technical or biological nutrients. The basic C2C concept which was utlised was “Waste=Food”, as the most important standardised design strategies which aim mainly to the recyclability or reuse of preconditon for a closed loop design. The frst part of systematsaton of the building aimed to the identfcaton of design is a design criteria which needs to be met in order for the materials to remain in criteria and tools which can allow for the design of the building systems through productve use for the natural and/or industrial environments. As far as the aspects Contnuing, in the part of materials’ and processes’ health for humans and the the effect of working with Cradle to Cradle of materials’ health and perpetual recovery are concerned, more challenges arise, environment, selecton criteria related to the materials’ life cycle impacts and health since a deep knowledge of other disciplines such as chemistry and industrial hazards were defned through relevant theoretcal studies and collected data based Throughout the research process, from the theoretcal to the design phase, aspects ecology is required for the maximum understanding of materials nature and fows on literature review and existng enquiries.
