Övervakning vid allmän anestesi och stående ingrepp på häst

The purpose of this literature study was to describe techniques for monitoring general anesthesia and standing chemical restraint in the horse. A number of various techniques and devices related to e.g. blood pressure measurement, blood gas analysis and pulse oximetry are defined, and finally their clinical relevance and reliability are discussed. The equine patient is generally far more exposed to anesthesia-related risks than other smaller species. Complications such as hypotension and hypercapnia are commonly seen during general anesthesia. Thus, close monitoring is essentially performed by the veterinary nurse, whom is responsible for monitoring the anesthetized patient.

Analys av konsignationslager : inom tillverkande industri

In this composition, a study of consignment inventory on basis of the factors which are important for implementation and application of consignment inventory are made. Logistics chain from subcontractor to end customer is becoming more complex when the volume of items constantly increases to satisfy the needs of the market. From that perspective, companies had large inventories but today it is a lot of different solutions to streamline inventory management. One way that recently becomes increasingly common is to let the subcontractor fill up the customers stock using different approaches such as VMI (Vendor Managed Inventory). A further step in the evolution can be to make use of consignment inventory where the vendor owns the stock of the customer.

Hur skall skogen skötas? ? en analys av skogsfastigheten Fagerdal 2:10 i Jämtland

The forest property Fagerdal 2:10 was donated to the Swedish University of Agriculture in 1995 by Erik Rönnberg. The dominating species is Norwegian spruce (Picea Abies) and the average age is high due to selective cutting. The aim of this study has been to analyze how the forest on the property should be managed and demonstrate how a better estimated forest data affects the future management. The impact of the management on the carbon stock of the property was also examined. A forestry plan established in 2009 by Skogssällskapet was used as a basis for the analyses.

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.

Begomovirus prevalence and diversity in the TYLCV resistant tomato cultivar Shanty in Nicaragua

Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive yield losses are followed by large economical losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve yields. Still, begomovirus infection is a large threat to the tomato production. Therefore, ongoing work in Nicaragua is focusing on finding new, better, begomovirus tolerant or resistant tomato cultivars.

A literature study on Methicillin-resistant Staphylococcus pseudintermedius (MRSP) : classification, resistance mechanisms, risk factors and clonal distribution

The increased frequency of reported Methicillin-resistant Staphylococcus pseudintermedius (MRSP) is of great concern to small animal healthcare due to limited options of antimicrobial therapy. The aim of this literature study is to investigate 1) characteristics and classification of S. pseudintermedius, 2) resistance mechanisms and emergence of MRSP, 3) risk factors for selection of MRSP, and 4) clonal distribution around the world. S. pseudintermedius is a skin and mucosal commensal in healthy dogs and cats, but can cause infections, including pyoderma. Beta-lactam antibiotics inhibit bacterial growth by binding to the penicillin binding protein (PBP), a vital enzyme in the synthesis of the bacterial cell wall.

Metodjämförelse mellan instrumenten Vitros 5,1 FS och QuikRead CRP för analysen P-CRP

In studies of serum, in the early 1930s, from patients with pneumonia, a factor was found. It could agglutinate certain pneumococcal species. This factor, which later became known as C-reactive protein (CRP), increased sharply during the early and middle stages of the disease. CRP was identified as an acute phase protein and found especially in bacterial infections. CRP is synthesized in the liver by stimulation of interleukin 6 (IL-6), which is produced by the monocytes, and consists of five non-covalently bound subunits.The aim of this study was to compare two different analytical instruments (Vitros 5.1 FS Ortho-Clinical Diagnostics and QuikRead CRP Orion Diagnostica) for CRP analysis.

Akut mikrocystinförgiftning hos däggdjur

Förgiftningar hos däggdjur som druckit vatten kontaminerat med cyanotoxiner har observerats världen över, och riskerar att öka i takt med tilltagande övergödning och klimatförändringar. Denna litteraturstudie inriktar sig på mikrocystin (MC) som är det vanligaste och mest studerade cyanotoxinet. Studien avgränsar sig till akut intoxikation hos däggdjur och fokuserar på grundläggande mekanismer hos toxinet, såsom absorption, distribution, metabolism och elimination. Vidare beskrivs de toxiska mekanismerna och de akuta toxiska effekterna. MC orsakar utbredda nekroser och blödningar i levern. Den specifika distributionen till levern anses bero på det höga uttrycket av organiska anjontransportörer (OATP).

Selection of habitat and resources during migration by a large mammal : a case study of moose in northern Sweden

Migration is a worldwide phenomenon that has occurred for thousands of years in a vast variety of species. The general knowledge of migrating animals is poor even though billions of animals from a range of different groups migrate every year. The human impact on migrating ungulates is high and many populations are declining globally due to direct and indirect causes. Hence it becomes vital to study the migration phase and the habitat and resources selected during migration. The objective with this study was to identify the habitat characteristics and resource selection of moose during migration and compare the selection between different seasons and utilization distribution (relative frequency distribution for the points of location of an animal over a period of time) categories.

Den globala uppvärmningen : vad kommer att hända med morgondagens värld?

Mankind faces a serious threat. Its activities, for example the burning of fossil fuels, have led to an enhancement of the greenhouse effect - something that has given rise to a global warming. The climate is becoming warmer, a change that has important effects on the nature as well as for humans and their society. Sea level rising, extreme temperatures are becoming more common, glaciers and other ice caps melt and storms becomes more intense when they appear. The main cause is the emission of greenhouse gases into the atmosphere - carbon dioxide in particular.

Nitrogen fixation among boreal feather mosses along a clear-cut chronosequence

The Swedish boreal forests are limited by nitrogen (N) availability. While biological N2 fixation by cyanobacteria hosted by pleurocarpous feather mosses are important sources of N input to natural boreal forest ecosystems, little is known about the patterns of N2 fixation in silvicultural systems. This study investigates the biological N2 fixation rates of two boreal feather moss species (Pleurozium schreberi and Hylocomium splendens) along a chronosequence from clear-cut to mature forest, as well as the vegetation characteristics along the chronosequence. Measurements and samples were collected from 32 forest sites that were classified into four age classes (clear-cut, pre-commercially thinned, thinned and mature forest). The sites were located near the city of Arvidsjaur in northern Sweden.

Francisella tularensis subspecies holarctica : the curious case of a water- and mosquito associated bacterium in Sweden

Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.

Skillnader i kungsörnens (Aquila chrysaetos) flyttningsmönster beroende på ålder och klimatfaktorer : En studie för skyddet av kungsörn

This study examines the factors that influence the seasonal movements of Golden Eagles (Aquila chrysaetos), and can thus provide important information that helps to improve the protection of the species. There were two main purposes of this study. First, I wanted to analyze the difference between preferences of juvenile and adult Golden Eagles in their choice of southern or northern hibernation areas. Do younger eagles prefer moving longer distance to southern areas of Sweden? Second, I wanted to investigate how the climate influenced the choice of date of migration in the fall.

Handelshinder som policy. Exportkontrollens effektivitet och påverkan på Sveriges handel med krigsmateriel 1984-2010 kopplat till policyutveckling.

The purpose of this thesis is to analyze the regulatory power, efficiency and impact of export control on Swedish arms export from the 1980s onwards, linked to the delegation of authority of permit license to the Inspectorate of Strategic Products in 1997. An increase in the administrative sector, based on a collective decision making process and established criteria and guidelines, aimed to strengthen the control of arms export to non-democratic and problematic states. In short, the aim of the study is to investigate and analyze whether there was a decrease in the arms export to problematic states or not. On one hand, it is reasonable to assume that the introduction of the new regulation entailed a more strict arms export policy. However, previous research has showed that regulations are sometimes not effective since incentives to breach these may be present.The study begins by examining the Swedish case and situation in terms of arms manufacturing and export, as well as the delegation of authority and legislation applied to the field over time.

Grafisk skärpa : ett arbete om gaturummet

The streetscape is a complex environment with a lot of different parts and users. If you look at the streetscapes main parts you have floor, walls, roof and furniture. The floor in the streetscape, the street, consists of the ground and the paving. It can be made of a lot of different materials with both architectonic and practical functions. The walls usually consist of the houses. They have a big influence on the streetscape depending on architecture, heights and widths.
