Broiler production in Zambia - management, growth, diseases and welfare
Successful broiler production in hot climates requires knowledge of how birds are affected by heat stress. It is important with access to water and good ventilation to facilitate coping with the heat. It may be useful to reduce the consumption of feed during the hottest hours of the days, which together with a few hours of extra light available could improve both productivity and animal welfare.
The vision in birds is superior to that of humans and most other mammals. Continuous light and light with low intensity can cause eye injuries, affect the eye development in young chicken negatively, as well as provide increased incidence of foot pad lesions. Access to light affects the production but also the welfare of birds.
Anstaltspersonals erfarenheter och påverkan av hot och våld på arbetet : en kvalitativ studie
The aim of this paper was to describe the phenomenon of threats and violence within a Swedish penal institution. The study was thematized according to the three main research questions. These were as follows; The threats and violence prison staff have experienced in their workplace (I) how these experiences affected them in their work performances (II) and in their private life (III). By a qualitative design, in-depth interviews were carried out with four persons who are, or formerly have been, gainfully employed at a penal institution. Concepts from the theory of symbolic interactionism and a theory of human action have been used in the analysing process of this paper.
Samband mellan en längre tillväxtsäsong och en ökad smoltstorlek i Vänerområdet
AbstractThe purpose of this study was to see if there is a connection between smolt length from Brattfors salmon cultivation and temperature. Climate changes are expected to give a higher temperature that could result in a longer growing season for the fish.Cultivated smolt is today bigger than it was before, it is also bigger than the wild salmon. The growth season of salmonids depend on the water temperature, salmonids need 6-80C to grow. Water temperature has been surveyd since the late 50´s in Brattfors. The result shows that it?s now considerable more days per year with higher temperature.
Den rådande tolkningen av samma eller likartad verksamhet : Konsekvenser vid generationsskiften i fåmansföretag
On the 26th of January 2010, the Supreme Administrative Court in Sweden gave five rulings which greatly affect the possibility to keep a close company within a family by transferring the ownership of the company to the next generation. The five rulings concern the interpretation of the prerequisite, same or similar activity, which can be found in section 57, clause 4 of the Swedish Income Tax Act. The prerequisite is fulfilled when an entire or parts of a business is transferred to another close company and the receiving company?s business activity is within the framework of the transferring company?s business activity or when the companies have a similar connection. Depending on which shares that are being evaluated, the prerequisite can refer to both the shares in the receiving or the transferring company. When the prerequisite is fulfilled, a standardized amount of the business income will be taxed as capital gains and the surplus will be taxed as earned income.
Vacuumassisterad sa?rbehandling pa? en ka?rlkirurgisk va?rdavdelning ? Utva?rdering av behandlingsresultat pa? olika sa?rtyper och hur patienter skattar sin sma?rta i samband med byte av VAC-svamp : En journalgranskningsstudie
Background: Vacuum assisted closure, VAC, is a method which can benefit wound closure. There are not many reliable studies about the effects of VAC in different types of wounds. Previous studies have shown that patients have experienced pain during dressing changes.Aim: The aim of the study was to survey in what kind of wounds the vascular surgery ward have been using VAC, to study the treatment process of VAC and how it has been documented and also to investigate if patients with VAC experienced pain during dressing changes.Method: The patients were chosen from a ledger, which contained 77 patients that had been treated with VAC on the vascular surgery ward. Data were collected with a journal survey protocol.Results: The result is based on 67 patients with a total of 79 wounds. VAC was shown to have a good effect on wound healing and infected surgical wounds were the most commonly wound category undergoing treatment with VAC.

AbstractDegree thesis Solid content in Lime Mud By Andre Flodin Process operator program ? Umeå University 17/6 ? 2014 Pages: 21A thesis was made on Billerudkorsnäs production unit in Karlsborg where lime kiln in the causticising department of chemical recovery plant does not meet the required production. Causticising department is the final step in the chemical recycling unit. There, the filtered green liquor is mixed with lime to recover the cooking chemicals used in the pulp factory. The cooking liquid is called white liquor.
Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements
The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive.
The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of
association analyses.
Får man skriva så här? : En feministisk undersökning av mottagandet i recensioner i svensk dagspress av fyra romaner med bekännelsekaraktär
The purpose with this thesis is to examine how four novels with a trait of confession written between 1996 and 2001 have been received in the Swedish daily press. This is done from a feministic perspective. The study is based on 36 reviews and the method which is used consists of a close-reading of the reviews, where the following questions are asked to the texts: Are there examples of reception in sexual analogies?; Are the novels ascribed a status of universality or are they considered to be something private?; How does the reviewers comment the exposure of the authors themselves and persons close to them?; What does the positive versus negative criticism concentrate on?; How does the reviewers comment the sexual element in the novels? The theoretical framework focuses on how womens literature has been treated in literary criticism and the treatment of the confession novels in the 1970s. The analysis of the reviews has, among many other things, showed that the novels mostly are regarded as something private; that the reviewers for different reasons question the publishing of the novels and that there are things concerning women and sexuality that is not accepted to write about.
Att leva med kroniskt obstruktiv lungsjukdom : En litteraturöversikt över patienters upplevelser
Background: A health damage that has been specifically related to nursing is pressure ulcers. Pressure ulcers are a complication caused by disease, care and treatment and can result in great suffering for the patient. Pressure ulcers can affect people both physically and psychosocially and is experienced, by most patients, as a serious and unnecessary complication of care. Today there are hundreds of identified risk factors for pressure ulcers described that can be divided into patient and care-related risk factors. A successful pressure ulcer prevention and treatment is to reduce or eliminate the underlying causes for the development of pressure ulcers, prevent deterioration and to treat existing ulcers.
Flavour improvement of water solutions comprising bitter amino acids
The aim of this project was to improve taste of a liquid food product, comprising extremelybitter and unpalatable amino acids and one unrevealed ingredient. The amino acids were Lleucine,L-isoleucine, L-valine, L-threonine and L-lysine monohydrochloride. Experimentaldesign was set up as a screening of water solutions comprising these ingredients (called BCAAsolutions) and added ingredients with potential to improve flavour. BCAA solution withingredients that were potential bitterness suppressors were evaluated in flavour, bitternessand/or palatability. Solutions of separate amino acids were also studied.
Det växer ju inte i magen men det växer i hjärtat : En kvalitativ studie om adoptivföräldrars erfarenheter av adoption
To investigate adoptions are part of the social worker's duties. The aim of our study was to examine some adoptive parents, to internationally adopted children, experience of adopting, the time before the adoption, the adoption process, and the time after the adoption. The study is based on qualitative interviews with seven adoptive parents. Theoretical frameworks that have been used are a phenomenological perspective, the dramaturgical perspective of Goffman and the theory of rites of passage.The result of our study shows that the adoptive parents have tried ?everything? to be-come parents in a biological way before they came to the decision to adopt.
Induktion av persisterande gulkropp hos sto : en framtida metod för att dämpa brunstrelaterade störningar?
This article starts with a review of the literature regarding the normal reproductive physiology of the mare, normal luteolysis, different causes of prolonged luteal phase and theories behind these. The article also presents a study where it was examined if treatment with human choriongonadotropic hormone (hCG) during the luteal phase induces prolonged luteal phase in mares, thus preventing estrus. The study consisted of two parts: one intensive study of eight mares at the former Department of Obstetrics and Gynaecology at SLU, Uppsala, Sweden and one field study of seven mares at a stud farm 70 km north of Uppsala. The mares in the intensive study were divided in two groups: one with four mares that were injected with hCG in luteal phase when they had a follicle of minimum 30 mm and a second group with four mares that were injected with sodium chloride at the same time. These mares were examined with ultrasonography and blood samples.
Rekonditionering av IBC
This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. Structures subjected to resonance can risk great damage and destruction, why resonance is something that is important to take into account when designing structures. Alternative ways to counteract resonance is to supply damping in the system. Damping means that the resonance decreases instead of letting the amplitude increase.The report discusses some examples on constructions that have experienced the effect of resonance.
Trä som fasadmaterial ? behandling och beständighet
Since prehistoric time man has used wood to build their environment. The material?s availabilitycombined with its good mechanical properties has often made it the material of choice. Like allmaterials exposed to natures degradative processes the properties of wood decreases over time.Rot, UV radiation and attacks by insects and pests damage wood if not protected. Since we wantwhat we build to consist, optimizing our building materials durability is of great interest.Techniques and methods for increasing the endurance of wood have been developed in severaldifferent places and for a long time.
Solel och solvärme ur LCC-perspektiv för ett passiv-flerbostadshus
This master?s degree project concerns the combination of a multi dwelling passive house with solar energy for the generation of electricity and domestic hot water (DHW). Different alternatives with either solar thermal systems or photovoltaic (PV) systems are compared with two reference alternatives producing DHW from electricity or district heating. The economical comparison uses a life cycle cost (LCC) perspective based on the present value of expenditures for investment, energy and annual operating and maintenance.The energy yields from the solar energy systems were calculated by hand and with simulation software. Calculation and dimensioning of PV systems were carried out with a software called PVSYST.
