Mekanisk modell av människans huvud för simulering av skalltrauma och hjärnskada

In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

Förebyggande Brandskydd

The number of residential fires has not declined sufficiently since the smoke alarm entranced the Swedish homes, fires lead to devastating consequences in which possessions, homes and worst of all human lives are at stake. Every year, about 80 people get killed and more than 500 get´s injured in residential fires, often due to lack of safety equipment. The number of fires caused by electrical appliances has risen and taken over a period of ten years the fire caused by a forgotten stove has increased by 70 percent. Preventing the risk that a fire would start on the stove would saves money, worry and most importantly, lives..

HRM i Mikrotjänsteföretag

The purpose of this essay was to find out how leaders in micro service firms practice HRM and identify which HRM related problems they experience in their leadership. A case study consisting two cases was carried out. The study has shown that leaders in micro service firms use a highly personalised, informal management and involve their employees in the firm?s development. The findings were that leaders of micro service firms do not have any theoretical knowledge of HRM practises because of lack of education.

Inter-species embryo transfer in South American camelids

Embryotransfer är en metod där ett embryo i tidigt stadium flyttas från en donator till ett mottagardjur som sedan bär dräktigheten till förlossning. Det innebär att donatorhonan kan donera flera embryon under en säsong då den vanligtvis endast skulle kunna producera en avkomma. Embryo transfer är således en metod för att snabba på det genetiska urvalet i en grupp djur. Bland de mycket ekonomiskt värdefulla alpackorna i Peru, där många av herdarna saknar alternativa inkomstkällor kan embryo transfer bidra till ett mer effektivt avelsarbete och i förlängningen en bättre levnadsstandard för alpackaherdarna och deras familjer. Studien beskriver ett experiment där ett protokoll för embryo transfer från alpacka till lama utförs under fältmässiga omständigheter på en forskningsstation i de peruanska Anderna.

Hållbar utveckling och CSR inom foderindustrin för hund och katt : Med fokus på det ekologiska perspektivet

Pets like dogs and cats have a considerable importance for humans and research demonstrate a variety of positive economic and social effects in society due to our pet companions. The presences of pets are increasing on a global scale with correlation to economic development in low- and middle income countries. For example dogs have doubled in India over a five year period. The feed industry for dogs and cats is also the fastest growing sector in the food industry and certain pets have a significant animal protein intake which, depending on the choice of resources may provide a high ecological footprint. Examples of environmental effects with distribution and manufacturing of pet food are increased greenhouse gas emissions, waste, use of water and energy.

Evaluation of a selective media for the detection of gram-positive bacteria in leg ulcers and pressure wounds

Hard-to-heal ulcers are resource intensive due to the fact that they are difficult to treat and especially vulnerable to bacterial invasion. The bacterial culture contaminating these wounds often consist of several different bacterial organisms that originate from endogenous sources. Necrotic material in ischemic ulcers provide nutrition which support bacterial reproduction, increasing the risk of infection. Determining causative pathogen in infected ulcers proves to be difficult when culturing swab samples, however Staphylococcus aureus and hemolytic streptococci generally act as primary pathogens.    The aim of the study was to investigate if the detection rate increased for S. aureus and hemolytic streptococci when culturing swab samples from ulcers on Columbia CNA; a media selective for gram-positive bacteria.

Unesco, Malraux och ombildningens museum : Estetik och kosmopolitik i efterkrigstid

An inquiry into the post-war European aesthetic and political landscape should take the international organization Unesco?s colour reproductions and travelling exhibitions of paintings into consideration. In these, the organization implements André Malraux? idea of the ?imaginary museum? as a framework for a future cosmopolitical, aesthetic (and utopian) community. During the late 1940?s, the Swedish government also discusses the need for raising an ?aesthetic awareness? amongst their citizens as a consequence to a poor knowledge in the fine arts.

Synchronizing migration with birth: an exploration of migratory tactics in female moose

Migration and giving birth are crucial decisions for animals during their life cycle, which may have lasting consequences on their population demography and fitness. Migration can entail a variety of possible effects for an individual, such as access to high quality food and reduced risk for predation. The moose (Alces alces) in northern Sweden is partially migratory and moose females are known to give birth to one or two calves. The synchrony between time of calving and timing of migration has not been compared before, especially in terms of energy maximizing and time minimizing perspectives, which may provide vital cues for fitness benefits of migration. I investigated effect of timing of birth and individual life history on distance, timing, stopovers and duration of 190 individually marked female moose that have been tracked for multiple years in ten different areas in northern Sweden.

Is the Use of the Rubber as a Preventive Measure to the Spread of HIV/AIDS Morally Justifiable? Ethical Reflections on the Controversy

Since the Human Immunodeficiency Virus (HIV) that causes Acquired Immune Deficiency Syndrome (AIDS) was discovered in the 1980s, the condom has scientifically proven to be the only technological device that can prevent transmission of the virus during sexual intercourse. This technical approach to the HIV has strongly emphasized that prevention is only possible if the condom is properly used. However, as a technological artifact the condom has shown that its use is laden with values. The question of values on condoms has brought in a heated debate on the moral justifications of its use. In Malawi, just as in other African countries, the Faith Community has rejected the Governmentsplea to promote condoms as the preventive measure against the virus.The Faith Community has emphasized on abstinence and mutual faithfulness as the only reliable means to the prevention of HIV/AIDS.

Use of feline TK1 as a biomarker in disease monitoring

Serum thymidine kinase 1 (TK1) activity is used as a tumor marker in disease monitoring in veterinary and human medicine. TK1, an intracellular enzyme, is involved in a salvage pathway of DNA precursor synthesis. TK1 is used in DNA precursor production by catalyzing the transfer of the gamma-phosphate-group from a phosphate-donor to the 5?- hydroxyl-group of thymidine forming thymidine-monophosphate. Nucleoside monophosphosphates are finally converted into thymidine-triphosphates. TK1 activity significantly rises in the G1 and the S phase of the cell cycle.

By interviewing people who live in the countryside in the municipality of Hässleholm I?ve tried to get a picture of how the thoughts on development of countryside are. Trough these interviews I?ve also tried to find out how people on the countryside defines the concept of countryside.

Allt har förändrats men ändå ingenting

Everything has changed, yet everything is the sameUsually, there is no reason for people to think about death or illness, although it is a highlynatural part of life. Most people live in health without major problems. When something does happen, people assume it will be at the end of their life and then it will be a natural part ofgrowing old. Yet some will get the notice or the feeling that something is not the way it should be, it can be something they can live with or they may have to face death.The work concerns the body?s fragility and feelings about human vulnerability.

Ungdomar, religion & religiositet En undersökning om ungdomars syn på religion och religiositet

This is a study concern high school student?s view of religion and their religiosity. I dispensed a questionnaire to 124 high school students studying comparative religion in a large high school in Sweden, with the students from different socio-economic backgrounds. The result I came up with is that traditional religion activities have decreased, religion has not disappeared but taken other shapes than before. And I also came up to with the result that more than half of them who answered the survey likes the subject and there are tendencies by them who doesn?t like the high school subject religion that they live in a non-religious family.The study concerns following aspects: sociology, youth, human needs, religion, spirituality and individualization..

Optimering av fackverksmodellering : Ett makro för Tekla Structures

This project is the result of a cooperation between HalmstadUniversity and EABAB. The aim of the project was to create a macro that would help EABAB automate the process of designing steel trusses. When run in Microsoft Excel, the macro imports and processes coordinates from a calculator program. The data is then imported into the Building Information Modelling software Tekla Structures, which creates a 3D structural model of the steel truss.The macro saves much time in the project planning process and also helps minimize the risk of design flaws caused by human error. .
