Evaluation of lithium-heparintube analyses performance
Today, some kind of laboratory results is required for around 70% of the diagnostics and follow-ups for diseases. In many of the cases the time from sampling to a result is very critical. Therefore the discussion of how to improve this situation has begun. For many analyses serum has been the routine choice for a long time but now it is disputed. After blood collection in a serum tube it is essential to wait 30-60 minutes before centrifugation and analysis of the sample, a long time for someone in an acute state.
Hästavmaskningsmedels påverkan på miljö och välfärd
Healthy, natural pastures is very valuable for biodiversity in the form of both plants and animals. An efficient use of pastures helps to preserve biodiversity, but grazing animals needs to be de-wormed to keep them healthy and to prevent harmful parasites spread on the pasture. The awareness about the environmental impact of the frequent use of deworming agents is low among the public. Some people are unaware that the absorption in horses of anthelmintics is incomplete, which make the circumstances about enviromental effect important to investigate further. The scientific evidence in this area is limited and more studies and trials are needed to deepen the knowledge about the effects of anthelmintics in the environment.
Hästunderstödd terapi : En kvalitativ studie om professionellas syn på Hästunderstödd terapi
Historically, the horse has in many ways been important to human beings. Today, Equine Assisted Therapy is a form of treatment in which the horse is used as a tool from the treatment of the client. Supported Equine therapy has a therapeutic purpose and may vary depending on the patient's needs and the professionals work competence. Various studies show that animals have a positive impact on people. The aim of our study was to explore how Equine Assisted Therapy is used within the practical fields of social work in Sweden.
Reagera och agera: Styrka och snabbhet i den manuella responsen för emotionella stimuli
In this study I investigated whether the strength in the manual response for emotional and neutral stimulus search arrays can explain some of the difference in reaction times (RT:s) for emotional stimuli, or not. Earlier, perceptual, cognitive and attentional processes has mostly been used to explain the variance in RT:s. Thirtythree individuals were asked to, as fast as possible, detect a target picture among distractor pictures in 3 rows x 4 columns arranged search arrays. The pictures were categorized in fear relevant animals (snake, spider) and neutral animals (cat). The results showed, more correct responses for cat target.
Hur påverkas dvärghamstrar av att vistas i hamsterbollar?
Lately the popularity to keep different species of dwarf hamsters has increased in Sweden.
The requirements of the Swedish legislation to keep hamsters as pets are low which could be a reason for the increasing popularity. Hamsters are in nature generally nocturnal and can travel far distances to find food sources during their active part of the day. Their eyesight is poor, but is compensated by their well-developed hearing and olfaction. ?Run about balls? are made of plastic and the hamster is placed inside it where after the ball is placed on the floor and the hamster can then run protected outside the cage.
"Ibland hjälper han mig mer än vad alla ni i personalen gör." : Hur djur i vården påverkar välbefinnandet hos personer med långvarig ohälsa - en litteraturstudie
Background: Animals have been shown to have a positive effect on people. The nursing science approach says that a person can experience well-being despite illness. The positive attributes of animals can be used in health care to help ill people experience well-being. An animal-assisted intervention can be a form of activity or therapy involving pets (AAA / AAT) or horses (EAT).Aim: The purpose of this study was to elucidate how animals in health care promote well-being for people with long-term illness.Methods: Literature review based on fourteen original scientific articles, with both qualitative and quantitative approach.Results: The compilation of the results led to four main categories with two subcategories respectively. These were: Physical aspects with subcategories Physical well-being and Bodily functions; Psychic aspects with subcategories Psychic well-being and Reduced psychiatric symptoms; Existential aspects with subcategories Quality of Life and Safety; Social Aspects with subcategories Social behavior and Relationships.Discussions: Review and discussion of the selected method.
Smärta hos djur :
We have made a litterature study about pain in animals. In this studie we have brought up
areas like sign of pains in animals, pain relief and the care perspective.
Pain is perceived when body tissue is damaged or nearly damaged by stimuli. Nociceptors,
which are receptors placed at nerve endings, responds to a provocation of pain and
transmit an impulse along the nerve to the brain via the spinal cord. Pain is urgent or
chronic, and can be divided into nociceptive pain (somatic pain and visceral pain) and
neuropathic pain. Different pain mechanisms can arise, such as referred pain, which is
when signals of pain are referred to other parts of the body.
Salmonellosis in Peruvian guinea pig production : a study to evaluate the prevalence of salmonella spp and importance of the disease
In Peru guinea pigs are raised for meat production and salmonellosis is considered as a major problem. Studies have detected salmonella in animals with enteritis and pneumonia. Salmonellosis exists both in an acute and a chronic form. In the rural areas the diagnosis is made according to clinical signs and macro pathological findings at autopsy.
The major systems applied for the guinea pig production are often classified as family, family-commercial and commercial. These systems differ in number of animals and how industrialised they are.
Majsensilage i Sverige
Maize for silage has been used as fodder in different parts of the world for a long time and has recently become more common also in Sweden. Our cold climate has been a problem as maize is very sensitive to low temperatures and frost. With new varieties and better techniques for cultivation it is now possible to grow maize in the southern and middle parts of Sweden. As for the north of Sweden the length of the cultivation season is a limiting factor as there are too few days with temperatures of over +10 ºC. Maize is well suited for silage making but oxygen-free conditions are required.
Matematiksvårigheter : En studie om fyra pedagogers erfarenheter kring matematiksvårigheter med exempel på pedagogiskt arbetssätt
For many years, I have tried to understand why students end up in difficulties in mathematics. As a future teacher, it is extremely important to have knowledge of the various factors that leads to difficulties in mathematics. As a teacher it is obvious to meet the students who find mathematics a difficult subject, and, therefore it is necessary to have a broader knowledge of how to respond and support these students. According to Ahlberg, number of students with mathematics difficulties is increasing every year, therefore, it is important to help students and organize a supporting school environment that promotes and encourages learning (Ahlberg 2001, p. 104-105).
Flockning och förtjockning i High-Rate-förtjockare ? en jämförelse med konventionell förtjockarteknik och lamellsedimentering.
In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.
Nötkreaturens val av betesvegetation på naturliga betesmarker :
This study concerns the type of vegetation selected by cattle grazing on semi-natural pastures, and whether the selection depends on the nutrient content of the vegetation or on other factors.
The study was carried out in three different semi-natural pastures in the Uppsala area during June, July and August in 2006. The three pastures were first surveyed, mapped out and divided into sub-areas with regard to the type of dominating vegetation. The vegetation types identified were: wet, mesic, dry, wooded, pasture with signs of former cultivation (arable). Within each vegetation type three 1x1 m sampling plots were laid out.
The grazing behaviour of the cows was recorded in a behaviour study.
When and what determines the death of an animal? A study investigating the heart activity during slaughter of farm animals
Slaughter of animals should consist of two steps in order to be considered humane. The first step of the slaughter process is stunning, with the purpose of inducing unconsciousness and insensibility in the animal. The second step is exsanguination, which causes bleeding and eventually death. What death really means in these situations has been discussed intensively, but still no agreed definition has been accepted. Nonetheless, it is conceded that animals are declared dead when consciousness is irreversibly lost, and absence of respiration and blood circulation are observed.
Exercise pens as an environmental enrichment for laboratory rabbits
This thesis analyzes the effects of different fertilization strategies on forest management at Holmen Skog in Umeå district. Harvesting volumes, net present values and fertilization intensity are presented for each fertilization scenario. The planning reserve (percentage area older than minimum final felling age) was also analyzed in this study.The thesis covers the analysis of five different fertilization scenarios, varying in fertilization intensity, from no fertilization at all, to fertilization at every harvesting operation (thinning or final felling). A sub-study was also carried out so the reader in detail can see how the different fertilization scenarios affect individual forest stands of different nature. The analysis has been done with the planning tool PlanWise, which is an application of the Heureka analysis and planning system.
Impact of EU-regulation on pigs? welfare during transport
Each year 225 million pigs are transported within the European Union (EU) for slaughter, fattening and breeding. This results in poor animal welfare due to the fact that animals are exposed to several numbers of stress factors in the vehicle during loading, transit and unloading. Animal welfare can be defined as how well the animal attempts to cope with its environment and during transport there is often severe difficulty for the pigs to cope properly. There is a growing societal concern for animal welfare. This resulted in that the European Union enacted a law called the EU-regulation with certain directives of how to improve the welfare of the animals during transport.
