When does the protein profile in milk normalize after antibiotic treatment against clinical mastitis?

Concentration of protein in bovine milk is one of the most significant milk quality parameters, to a large extent determining the price for milk to the producer. Mastitis is a common disease among dairy cows, negatively affecting not only milk yield but also milk protein composition. Milk from mastitic cows tends to have lower cheese yield, negatively affected processability properties and sensory quality, due to changed protein quality and composition. Poorer milk protein quality would have an economically negative impact on dairy industry. Only few studies have investigated the short term effects of mastitis on milk protein composition.

Undersökning av vissa beläggningars påverkan på antenners effektivitet i tågmiljö

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

Avrundar företag sina resultat - En studie av Cosmetic Earnings Management i Sverige

The aim of this thesis is to examine the occurrence of Cosmetic Earnings Management (CEM) among Swedish companies. CEM refers to the small upward rounding of reported net income to reach cognitive reference points. Important cognitive reference points are multiples of ten (N*10^x) of reported net income and rounding towards these has been documented in other markets around the world over the last 20 years. The occurrence of CEM on the Swedish market is studied using digital analysis, frequency testing and Benford's law. Firstly, reported net income of publicly traded companies between 1996 and 2010 is examined.

Evaluation of preanalytic methods in order to shorten the processing time before identification of fungal microorganisms by the MALDI-TOF MS

Identification of fungi is based on macroscopic observations of morphology and microscopic characteristics. These conventional methods are time-consuming and requires expert knowledge. For the past years Matrix-assisted laser desorption ionization-time of flight mass spectrometry has been used for routine bacterial identification in clinical laboratories but not yet in the same extension for fungi. In this study three preanalytic preparation methods for fungi were evaluated in order to shorten the processing time in routine laboratory performance.Clinically relevant strains (n=18) of molds and dermatophytes were cultivated on agar plates and prepared according to the different preparation methods for protein extraction. Each strain was analyzed in quadruplicate by the MALDI Biotyper and the database Filamentous Fungi Library 1.0.The results showed that the genus and species identification rates of the least time-consuming direct extraction method were 33% and 11% respectively.

"Syns man så finns man": illustratörers och bilders "synlighet" i Bibliotekstjänsts sambindninghäften 2001

The aim of this bachelor thesis is to see how illustrators and illustrations are treated in Bibliotekstjänst?s binding booklets compared to how authors and texts are treated, i.e. the picture versus the printed word. My aim is to try and find out if librarians have the aids to acquire information about picture-book illustrators and illustrations in their selective work and reference work. In order to find out about this I need to examine the most common aid in this work, i.e.

Research in computer graphics has since 1970 had as a main goal to achieve photorealism. When working on 3D-production for film, animation is a part of the process. This part aims to give life to digital characters, among other things.

Kapitalstrukturens effekt på lönsamhet : En studie av svenska företag

In this paper the effect of capital structure on profitability has been investigated among Swedish companies. The essay intends to examine how the relationship between debt and profitability appear among Swedish companies and if the relationship differs between industries. The purpose is to find out how debt affects the profitability of Swedish companies.A quantitative approach has been applied. The selection was made among companies listed on Nasdaq OMX Stockholm, which resulted in a sample of 207 companies. Several regression analyzes has been formed, based on the independent variable debt-ratio and the dependent variables profit margin, pre-tax profit margin, operating margin, return on assets and return on equity.

Undersökning av genuttrycket av homeoboxen HOX A6 vid pyometra samt försök att bygga upp en in vitro-modell för pyometra

This study had two different aims. The main aim was to investigate the dynamics and impact of African swine fever (ASF) on a farm in Uganda during a recent outbreak through a case study. The second aim was to estimate the presence of two important differential diagnoses of ASF: Classical swine fever (CSF) and Porcine Reproduction and Respiratory syndrome (PRRS).The field and laboratory based case study of the farm level dynamics of ASF virus during a recent outbreak (October-December 2010) on a farm in the district of Mityana, Uganda, was conducted, using interviews, ELISA and RT-PCR. The financial impact on the farm was also estimated. The impact of the outbreak was profound.

Modebloggarnas dolda budskap?

The accounting scandals that have attracted attention in recent years have led to internal control becoming a more central part of business activity. Doubts about what firms actually do have increased, all caused by the attention of accounting scandals. To counter this, frameworks and laws evolved and gained a significant role in the organization and its surroundings. The aim of the present study is to find out how four companies in the Kristianstad region are working to ensure its internal control and how they work to minimize risk and reduce uncertainty. We have used a qualitative method and interviewed a person in a senior position in each company.

Sänkta sjöars inverkan på ytvatten i Västerbottens kustland : Samband mellan sänkningsnivåer och vattenkemi i sjöar på sulfidrika sedimentjordar

Lake lowering in sulphide-rich areas is currently a major environmental impact for surface water. This study focuses on whether there is a relationship between a gradient of lake lowering and surface water impacts in areas of sulphide-rich sediments, in order to better understand their contribution of heavy metals and sulfuric acid. Also, is it a reasonable method to use the reduced lake area in order to quantify the gradient? The survey was conducted by collecting water samples from reference lakes and lowered lakes from south to north in coastal areas within the county of Västerbotten. Water samples were then analyzed for TOC, pH, conductivity, anions, base cations, alkalinity, acidity, sulfate, Al, Cd, Fe, Mn, Cu, Zn and Pb.

Fälttest av en ny metod att med objektiva mätmetoder karaktärisera egenskaperna hos ridunderlag- en pilotstudie. :

Background Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses. The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.

Effekten av kvävegödsling på gasproduktionen vintertid i boreala sjöar

To investigate effects of nitrogen on in-lake CO2 and CH4 production during winter, three pair of lakes was subject for a fertilizing experiment in which one lake in each pair was fertilized with nitric acid (HNO3) directly into the water column in the summer of 2012. The lakes in each pair are assumed to be morphologically, hydrologically and biologically similar, that is, the non-fertilized lakes are considered references. The pairs do differ in one major way by being progressively less humic, going from around 25 mg/l to 10 mg/l DOC. Sampling and analysis was carried out at the end of the frozen period in 2013. Results show a significantly higher concentration of both CO2 (p<0,001) and CH4 (?=0,1, p=0,053) between impact and reference sites in the two less humic pairs.

Tro, Hopp och Tveksamhet : En studie om profil, image och kommunikation för Svenska kyrkan Västerås

What does the Swedish church Västerås stand for today according to the employees and how do they want to profile themselves to the target group? What image and what expectations does the target group have of the Swedish church Västerås? How can the Swedish church Västerås communicate uniform, with the intent to create mutual value with the target group?The purpose of the study is to make recommendations to the Swedish church Västerås for their prospective communication plan by examining their profile and target group's image and expectations of the organization. The study also aims to examine how the Swedish church Västerås can communicate their brand uniform.The study applies a qualitative research with deductive approach. Data were collected through semi-structured interviews with a sample of the employees and focus groups with a sample of the target group.Better match between profile and image means that SkVs employees better understand the organization and can communicate more uniform which leads to a stronger brand identity. If SkV understands what is relevant for their target group, they can reduce the total cost of customer delivered value and thus increase the total value.

Utvärdering av solcellsanläggningen på Universeum

The main aim of this master thesis was to see the process of an interactive online reference service from idea to final product. The reference service we have studied is developed and used by the Library of the National Institute for Working Life in Stockholm, Sweden and goes by the name phibi. Our goal was to review the whole realization process from the reasons why a service like this was created, how the service was introduced and implemented inside the organisation and finally what the result and consequences were for both the library staff and for the users of the service. Phibi is designed to be a tool that fosters communication between the library staff and the remote users where the users get the opportunity to be helped with their questions by the library staff although they are not physically present in the library. To understand the process we conducted a case study with 11 interviews of the library staff, the superior and the initiator to phibi.

Koldioxidutsläpp vid vägbyggnad - en fallstudie med jämförelse av alternativa byggnadssätt

Abstract This degree project examines how much carbon dioxide that emits during the construction phase of a road project. This is to make it possible to compare how the amount of carbon dioxide differentiates between traditional road construction and Swepave construction, which is PEAB?s alternative way to design roads. To make the comparison a calculation tool has been produced. To compare the amount of carbon dioxide emissions a reference project was needed.
