Upprepad administrering av trimetoprim/sulfadiazin till neonatala föl : plasmaproteinbindning och effekt på serumbilirubinkoncentrationen

Today most dosages used in horse medicine are based on studies in adult horses. Since there are differences between adult and neonatal horses with respect to different pharmacological parameters this can cause problems when administring drugs to neonatal foals. Neonatal sepsis is a common cause of morbidity and mortality in foals and aggressive antibiotic treatment is needed immediately when sepsis is suspected. In Sweden the combination of trimethoprim/sulphadiazine and bensylpenicillin is often used as the initial treatment. When administering drugs, interactions can occur between the drugs and endogenous substances.

Passage Retrieval en studie av index

The aim with this thesis came out of a strong interest for Passage Retrieval. Our intention has not been to evaluate an IR-system. Instead our goal has been to analyze the result of indexing documents and their passages. We have been studying the weights of the different terms in the different indices, in comparison with other parameters like frequency, normalized frequency and the inversed document frequency. Further more we have been looking at how the weights are spread using for instance the standard deviation.

Adaptiv temperaturreglering av bostadshus

The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.

Utvärdering av röstträning på logopedprogrammet i Göteborg

The purpose of this study was to examine if there were anychanges in quality in the voices of speech and language pathology studentsafter four years of study at the University of Gothenburg. Recordings oftwenty student voices from the first and eight semesters were evaluatedperceptually by six speech-language pathologists. The parameters judgedwere: vocal fry, glottal attacks, strain, breathiness and resonant voice, usinga scale from 0 to 10. Acoustical measures were made of F0 mean andmedian to detect possible differences between the two recordings. Theresults show a significant decrease in vocal fry, glottal attacks and strain aswell as an increase in resonant voice and a significant decrease in F0 meanand median.

EN MILJ?STUDIE OM DE GEOKEMISKA F?RH?LLANDENA I SK?RHAMN, SVENSKA V?STKUSTEN

The following study aims to investigate the environmental conditions of the harbor of Sk?rhamn, a small fishing community on the west coast of Sweden. The interest to do so rose as a newly built apartment residence failed to connect the sewage pipes of 18 apartments, causing the untreated sewage running into the sea. The parameters accounted for are the C/N ratio, total organic carbon (TOC) as well as total nitrogen present (TN) and ?13C in the top ten centimeters of a sediment core retrieved in the Sk?rhamn harbour.

Havsöringens (Salmo trutta) lekvandring i Själsöån, Gotland.

In this study, the sea trout (Salmo trutta) spawning migration was studied in the river Själsöån, Gotland, to assess the main external factors determining upstream migration and seasonal changes in fish parameters. Additionally population trends were studied by examination of old data. The most important external factors for upstream migration were the air pressure, air temperature and wind direction. No significant difference was found between when males and females migrated upstream. Larger females in better condition started migration earlier than the smaller females in poorer condition.

Quartzene i gips : Densitet och hållfasthet

A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

Lakvattenrening och kontroll vid deponier : granskning och sammanställning

If not purified leachate from landfills would cause damages on the environment. At most landfills in Sweden local treatment of leachate is achieved, at the rest the leachate is transported to sewertreatment. While no comprehensive legal provisions for discharge exist in Sweden there is a difference in discharges between the installations for landfill. If no comprehensive legal provisions is produced guidance must improve.Treatment of leachate and self monitoring system at fifteen installations in Sweden has been studied and compared. A study of literature about different treatment solutions has also been performed.

Allanblackia stuhlmannii ? a tree under current domestication: what are the soil requirements?

Allanblackia is a genus of trees that grows in the rainforests of West, Central and Eastern Africa. Its big fruits contain seeds very rich in oil which has been used by local communities for cooking and making soaps. The native stands are threatened by overexploitation and the demand for the oil is much greater than the supply. Domestication programs, aiming at introducing the trees to small holder agroforestry systems, have been started for some of the species. The main aim of this study was to investigate the soil requirements of Allanblackia stuhlmannii in terms of chemical and physical parameters, as revealed by the soil conditions in native stands. Another aim was to see if these varied along an altitudinal transect.

Förebyggande av anestesirelaterad atelektasbildning.

Atelektaser uppsta?r inom tio minuter hos 90 % av alla patienter som so?vs och leder till fo?rsa?mrad syresa?ttning men kan a?ven leda till postoperativa lungkomplikationer. Syftet med studien var att beskriva hur anestesisjuksko?terskan med olika ventilationsstrategier kan fo?rebygga atelektasbildning under generell anestesi. Studien genomfo?rdes som en litteraturstudie da?r 19 vetenskapliga artiklar granskades och analyserades.

Riskpremien, vad ska man tro? : En studie med facit i hand

The market risk premium is one of the most important parameters in finance. Its value and the ways to calculate a risk premium for the market is a widely debated subject. This thesis examines numerous ways of calculating a risk premium for the Swedish market with regard to how good an estimation they make of a real risk premium. Estimations based on historical periods ranging from 20 to 85 years is calculated as well as a premium based on forward-looking estimates. The real risk premium is solved out for a selection of companies and an index with the help of CAPM.

Inflytande i teori och praktik : En kvalitativ maktanalys över arbetet med individuella planer enligt LSS

People with certain types of disabilities have the legal right to ask for an individual plan. The idea is that the plan should be a tool for the disabled to get more power and influence over the planned actions that involves their lives. The aim of this thesis was to study the individual circumstances of interpersonal power and influence in the work of individual plans. The study was done with a qualitative approach, where three executing officers and three individuals were interviewed. The results show that the conditions for the individual?s influence are far more complicated than at first glance.
