The purpose of this study was to describe perceived psychosocial work environment and musculoskeletal complaints among baggage handlers, and to evaluate whether there is any linear relationship between them. The study is a questionnaire based cross-sectional study, and part of an ongoing larger project. Therefore, the number of forms has been limited to those that were collected in the project by 2010-11-25 (N=117). The questions analyzed in the study come from the Copenhagen Psychosocial Questionnaire and ?Nordiska Ministerrådets formulär om besvär i rörelseorganen?, respectively.

The horse was domesticated about 6000 years ago. Since then humans have used the horse for different purposes, such as work force and in sports. Horses are social, group living animals that spend around 16-17 hours a day on grazing. Horses are often kept stabled in single boxes with a limited feeding time. The forage usually contains grain-based concentrates and roughage.

The Angola black-and-white colobus (Colobus angolensis palliatus) is a subspecies of Colobus angolensis inhabiting fragmented forests in coastal Kenya and Tanzania. C. angolensis is regarded as Least Concern in the red list of IUCN because its populations are abundant. However, the populations of C. a.

Each year, Heterobasidion spp. is a major cause of economic losses to forestry in the northernhemisphere, including Sweden. New results indicate that pre?commercial thinnings could be at riskfor Heterobasidion spp. infections.

The purpose of this study was to find out if motion movements, e.g. number of lying bouts and lying time with a registered activity monitoring sensor can detect an impending calving and thereby be used as a measure and an indicator for an upcoming calving. For this, automatically step sensors were used and were attached to one of the cows? hind leg. The sensor registered the individual step and movement activity of the cow.

Genom konstruktion och tillverkning av prototyper samt med hjälp av ljud- och flödesmätningar av dessa, tillsammans med standardmodellen, har vi lyckats förbättra flödet genom ventilen Al-db 450, producerad av Fresh AB i Gemla. För ljudmätningar har en testrigg konstruerats och tillverkats..

The aim of the study was to investigate whether the sedation method had an effect on the screening result for hip dysplasia (HD). Another aspect considered was if the dog?s weight had an impact on the results. This study was a follow up on the results from an earlier study of sedation routines in Swedish dogs. The breeds included in this study were the same as in the earlier one; German shepherd, Bernese mountain dog, Boxer, Newfoundland, Rottweiler, Saint Bernard, Golden and Labrador Retriever.

Kundrelationerna i svenska B2C-företag är inte lika goda som de var för 60 år sedan och de är inte lika goda som företagen skulle önska att de var. Forskningsfrågan och syftet med uppsatsen var därför att förklara vad som påverkar svenska B2C-företags beslut att utnyttja Radio Frequency Identification (RFID) som identifieringsteknik för att personliggöra kundrelationer inom sina lojalitetsprogram. Studien utfördes som en fallstudie då vi undersökte hur två stora svenska B2C-företag, IKEA Family och ICA, arbetade med lojalitetsprogram, identifieringstekniker och hur de ställde sig till alternativa identifieringstekniker gestaltat genom RFID. Studien utfördes med deduktiv ansats genom inledande teoriinsamling och därefter genom intervjuer med en intervjuperson på vardera företag. De slutsatser som sedermera kunde dras var att tillräcklig kunskap saknas kring RFID och dess potential, att det är en ekonomisk fråga och en stor investering för företag som inte brukar vara först att ta till sig ny teknik som dessutom inte är standardiserad samt att det skulle kunna kränka kundernas integritet och därmed ha motsatt effekt till lojalitetsprogrammens syfte..

The goal of this thesis work is to enable an existing UHF radar to operate in the VHF band instead. In order to achieve this, new coherent local oscillators are required. Different options are suggested and one of them is implemented and analyzed..

ABSTRACTThe principal aim of the study was to compare the feeding behaviour of cattle, sheep and goats on pasture and explain any differences between speices. Furthermore, I compared foraging behaviour between dry season and the beginning of the rainy season, in order to see any relationships between weather and behaviour.The study was carried out in Shompole in southern Kenya. Behavioural data were collected by observing herds of cattle, sheep and goats on pasture. The livestock were herded on pasture during the days and kept in bomas, where people live, during the nights. The weather in Shompole is characterized by high ambient temperature and low, bimodal rainfall.

The purpose with the study was to find a pattern in the behaviour of dairy cows which could be related to their social rank. A behavioural study was conducted at the University Cattle Research Centre (Kungsängen) in Uppsala, Sweden. The study included 12 lactating dairy cows, 6 high ranked and 6 low ranked. The cows were housed in a loose housing barn with an automatic milking system (AMS) to which they had access 24 hours a day. During the experiment the total number of cows in the barn was 46.

Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.

The top selection of Swedish beef bulls are evaluated yearly by Svensk Köttrasprövning AB at Gismestad. The bulls are selected from six different breeds; Angus, Blonde d´Aquitaine, Charolais, Hereford, Limousin and Simmental, and are kept on straw bedding apart from a concrete alley in front of the feeding area during the six months of evaluation period. The bulls are evaluated according to their fertility scores, growth, exterior and temperament and the exterior, body posture and claw conformation reflect important qualities for their longevity. In spite of good values for fertility, it has been noticed in the last years that the fertility results and longevity have been unsatisfactory and claw and/or bone disorders have been suspected as a contributory cause. Persson et al. (2007) studied breeding bulls from Gismestad and other places, which had been slaughtered due to poor fertility (no pregnancies in the herd during their last year in service).

Hydroware Elevation Technology AB sells control and regulation equipment for hydraulic elevators. The company now wants to investigate the possibility of changing their present softstarters to frequency inverters to supply power to their pump engines. They also want to investigate the possibility of future use in so called ?intelligent? houses.The purpose of this report is to investigate these possibilities..

This thesis examines and measures differences in effciency between L1- and L2 language use for solving referential problems. Quantitative measures used in the study were time and error frequency. Qualitative measures, such as how the tasks and the participants own performance were experienced, were measured by an post interview and two questionaires. Two different tasks, a sorting task and a construction task, in which each informant was given the role as a constructor or instructor, were used for data gathering. A total of 20 dyads, divided in two language groups (English and Swedish) participated in the study.
