Metoder för utvärdering av råmjölkskvalitet och passiv immunitet hos kalvar av mjölkras
För att säkerställa en god start i livet hos kalvar är råmjölken en viktig del. Upptag av antikroppar från råmjölk påverkas av många olika faktorer. En viktig faktor är kvaliteten hos den råmjölk som kalven utfodras med. Det finns olika sätt att kontrollera halten av antikroppar innan råmjölksgiva. Ett vanligt verktyg i svenska besättningar är kolostrometer som mäter densiteten i mjölken och utifrån denna kan ge en uppskattning av antikroppsinnehållet.
I detta examensarbete har en digital Brix-refraktometer och kolostrometern jämförts med infraröd spektroskopi.
Faktorer som relaterar till rökvanor bland svenska 11- och 15 åringar : en kvantitativ studie
Folkhälsa berör många samhällsområden och det är mycket viktigt att alla människor tar del av information och kunskap om hälsa. Rökning är en stor fara för folkhälsan som ständigt är aktuell och många projekt påbörjas just för att få en minskning av tobaksanvändning och förhindra ohälsa på grund av rökning. Särskilt viktigt är det att studera rökning bland unga. Syftet med den här uppsatsen är studera hur rökvanor ser ut och förändras bland ungdomar vid 11 och 15 års ålder och hur rökvanorna kan relateras till alkoholvanor, socioekonomi och fysisk aktivitet. Metoden innebar användning av enkätdata från Statens folkhälsoinstituts färdigställda enkäter.
Är ett framtida vaccin mot Alzheimers sjukdom möjligt?
Alzheimers sjukdom är en smygande neurodegenerativ demenssjukdom som främst drabbar äldre och som karakteriseras av uppkomsten av amyloidplack och neurofibriller i hjärnan. De vanligaste symptomen är demens, kognitiva problem, inbillningar och aggressivitet. Alzheimer förekommer i två olika former, presenil och senil alzheimer. Den fullständiga mekanismen bakom alzheimer är ännu okänd men två proteiner, beta-amyloid och tau, anses ligga bakom orsaken till alzheimer. Ett tredje inblandat protein som man funnit via genetisk analys är apolipoprotein E.
Lane Keeping Aid : ett förarstödjande system för bilar
Many traffic incidents are due to the driver?s lack of attention, resulting in dangerous lane departures, either sliding off theroad or into the oppose lane. These kinds of incidents often have serious outcomes, which has led to much effort being concentrated on preventing or lessening the damages when the incident is already a fact, for example by installing safety belts and air bags. These measures may be considered to be acts of so-called passive safety. Active safety on the other hand, means that the safety systems intervene before the incidents have occurred.
Ryttarens rotation av bäcken och överliv vid ridning i trav :
The aim of this study was to determine the basic movements of the riders? pelvis and upper body when riding in trot seated. The study was preformed at a treadmill with seven high level dressage horses and their riders. The movements of the horse and rider were captured with a motion analysis system (ProReflex®) and also recorded on video. The horses were ridden in collected trot, 3.0 m/s.
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.
Luftburna gifter som kemiskt stridsmedel : En jämförelse mellan moisternas rökkrigföring under de stridande staterna och tyskarnas klorutsläpp vid Ypres den 22 april 1915
Kemisk krigföring i form av luftburna gifter har förekommit i många historiska kontexter. Trots att luftburna gifter, som till exempel giftig rök och gas är likartade företeelser, har inte forskare kunnat enas om äldre former av denna krigföring är jämförbar med den moderna. Huvudorsaken är att deras analyser saknar teoretiska perspektiv som belyser hur respektive kontexts kemiska förutsättningar påverkar krigföringen.Syftet med den här undersökningen är att jämföra ett modernt nyttjande av luftburna gifter, tyskarnas första klorutsläpp vid Ypres 1915 med ett forntida exempel, den moistiska skolans användande av brandrök som gift under århundradena f. Kr. i Kina.
Kommunernas politisering : En studie av det politiska styret i Nyeds landskommun 1950-1962
This essay deals with the question of lines of development within the politics in the rural municipality of Nyed 1950-1962. The aim is to explore how local politics and policies were handled from two perspectives. Firstly the issue of conflict and consensus or majority rule and consensus. Here Arend Lijphard's theory of majority and consensus provides a theoretical base for the essay. Secondly the aim is to explore the actions of the local politicians with regards to leisure time policies to find out whether or not they ideologically belonged to the concept of ?folkhemmets kommun? by Ulla Ekström von Essen.The source material for this essay has been the minutes from the two major bodies of local politics in Nyed, kommunalfullmäktige and kommunalnämnden.
OneCore
The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.

Riskbilder och kontroll av ungas IKT-användning: En fallstudie
The use of Internet by children and teenagers has become a special field of interest. Certain risks are associated with young peoples use of this media and national and international measures have been taken to assess and counter these risks.Library and informationscience have approached the subject of risks by looking at different software´s, so called Internet filters, that is used to control and censor the access to Internet based resources. In the USA, where public services and institutions that provide Internet resources to children and youth have started to require censorship of the Internet, a debate has arisen concerning the use of so called Internet filters.The theoretical basis of this master´s thesis is related to the conception of risk, gender and childhood. The focus of the paper lies on young peoples use of information and communication technology (ICT) and how risks associated with young peoples use of the Internet is constructed by different parties involved in supplying Internet resources. By means of a case study at a primary school in Skåne and at the company Netscan in Malmö.
Aktiv förvaltning av fonder på Emerging Markets
The main purpose of this Master Thesis has been to evaluate whether active fund management is profitable on Emerging Markets. The material used to examine this consists of 106 actively managed funds, with varying length during the period 1988-2006 and who uses MSCI Emerging Markets (MSCI EM) as benchmark index. The thesis has been written under the supervision of the Asset Management Department of Länsförsäkringar AB (LFAB) and the Department of Production Economics, Linköping Institute of Technology. Apart from the main purpose, the methodology used is also meant to form a template for in-depth or similar studies, preferably by the assigner of this survey, LFAB.The results shows that the median manager underperforms the MSCI EM throughout the whole period, which leads to the conclusion is that active management on Emerging Markets is not profitable. A grouping of the funds based on tracking error still shows that a majority of the managers in all of the groups underperforms against the benchmark.
Om Lettlands utveckling som destination : en jämförelse av turismindustrin under landets självständighetsperioder
Latvia has been an independent state twice, the first time during the years 1918-1940 and the second time from the year 1991 and ahead. During these two periods Latvia has been a destination for tourists. The aim of this study is to describe how Latvia as a destination has developed during the years of independence. One further aim is to compare what Latvia?s tourism industry looked like during the same periods to descry similarities and differences.
Kvinnor, giv akt! En studie av uttryck f?r genusstrukturer och sk?tsamhetsideal i tidskriften Morgonbris under f?rsta v?rldskriget.
This thesis explores how the Swedish magazine Morgonbris depicted women's new roles in the workforce during World War I and whether these depictions challenged or upheld contemporary gender structures. The study addresses two main questions, how Morgonbris portrayed women's new roles in the workforce and how this portrayal challenged or upheld contemporary gender structures. And also how the magazine integrated the ideal of respectability to engage and mobilize female workers, analyzed through Ronny Ambj?rnsson's descriptions of respectability ideals.
Using Hirdman's gender system theory, which examines the maintenance of gender power structures through separation and hierarchy, and Ambj?rnsson's work on respectability ideals, the study employs a qualitative content analysis of articles from Morgonbris during the war years. By identifying and analyzing expressions of class and respectability ideals, the research uncovers strategies used to engage and mobilize female workers.
The results show that Morgonbris portrayed women's entry into traditionally male-dominated labor sectors as a significant shift that challenged established gender roles.
Automatisering av flexibel fixtur
This thesis was conducted at Linköping University and SAAB Aerostructures, Linköping, and focuses on the automation of flexible fixturing in machining applications. At Linköping University a project called "Koofix" is conducted with support from Strategiska stiftelsen and several manufacturing industries including SAAB Aerostructures. The purpose of this project is to develop a more cost-effective, flexible, technique for fixation of workpieces during processing and assembly.Fixtures are an important part during the machining process, especially if you process the parts with high accuracy. Today a large number of fixtures are used at SAAB and they would prefer to reduce the number of fixtures by using flexible fixtures instead. SAAB uses one fixture for each article and this result in a high fixture cost and it also takes time to design and construct a new fixture.There are several advantages with using a flexible fixture such as that you can process workpieces with different length, height and thickness in the same fixture.
