Hundhållning i bil : situationen i Sverige och effekter av utetemperaturen. Enkätundersökning och experimentell studie

The aims of this project were to describe the circumstances around dogs being left alone in cars, to investigate owners? knowledge of the risks associated with leaving dogs in cars and the relevant legislation and, finally, to study how changes in the air temperature and air composition in the car affect the dog. The project consisted of a survey of the literature, a questionnaire part and an experimental part. An important conclusion is the importance of the level of knowledge of owners, since there are several ways in which an owner can prevent their dog from heat stroke and, in the case of an eventual accident, their action can have direct consequences in minimizing the long-term damage to the dog and even whether or not it survives. Fewer than half of the owners in the study knew that for a dog suffering heat stroke, the most important thing is to bring the body temperature down. Only a third of dog owners knew that if a dog is left in a warm car and showing signs of heat stress, then the police should be contacted and the dog quickly helped out of the car.

Minskande andelar kraftfoder i foderstaten under betesperioden : effekt på mjölkavkastning och betesbeteende hos mjölkkor

Feed costs constitute a large part of the expenses of dairy farmers. Pasture is a high quality feed with a low cost. However, feeding with concentrates has been shown to enhance milk yield (Leaver, 1985; Bargo et al., 2003; Stockdale, 2004). The purpose with this study was to investigate how milk yield and milk composition were affected as the concentrate proportion in the diet decreased. Pasture behaviour was examined to see if the different concentrate levels affected the time cows spent grazing and ruminating.

Word-of-Mouse-Effektens Mörka Sida : - En experimentell studie om hur negativ information i dagens sociala medier påverkar konsumentuppfattningar

The Dark Side of the Word-of-Mouse Effect- An experimental study of how negative information in today?s social media can influence consumer perception As a result of the electronic revolution of information dissemination, social media as a phenomenon has come to play an important part, both in society at large but also when it comes to business and marketing. Nowadays, knowledge and opinions about brands and products are spread by reputation through a wide range of social media platforms, a phenomenon which in the literature is referred to as word-of-mouse or electronic word-of-mouth (eWOM).The purpose of this paper is to investigate how people?s opinions towards a company and its product are affected by negative information in terms of eWOM. Or more precisely, whether or not there is a difference in this effect depending on information content, concerning company values on the one hand and product attributes on the other.This was done in an experimental setting where two groups of respondents were subjected to fictitious information of different types using established social media platforms.

Ny teknik för kombisådd :

The use of combi-drilling during spring tillage has become very common in southern Sweden in recent years. Combi-drilling leads to fewer passes on the field and better plant nutrient utilisation. An example of a combi-drill is the Väderstad Rapid, which is very widely used in spring tillage in southern Sweden. The Rapid has separate fertiliser and seed coulters, which means that the draught requirement is relatively high. It thus requires large, heavy tractors, which compact the soil and are comparatively expensive to buy and run. A few years ago the Finnish combi-drill Tume Nova Combi came onto the Swedish market.

Samband mellan arbetsgrad och kinesiofobi hos vuxna individer med långvarig smärta och förändring av dessa variabler efter fyra veckors smärtrehabilitering

ABSTRACTPurpose: The purpose of the study was threefold. Firstly, to investigate if a four week program in pain rehabilitation had any effect on how much individuals with persistent pain worked and their degree of kinesiophobia. Secondly, to study if there was a correlation between how much these individuals worked and their degree of kinesiophobia. Thirdly, to study if there was a correlation between the change in these variables.Method: 112 patients who had participated in a four week rehabilitation program took part in the study. The study had a retrospective design, which was based on a review on medical records and consisted of three minor parts.

Karaktärisering av höstvetets avkastningskomponenter

Wheat yield depends on the number of ears per m2, the number of kernels per ear and the kernel weight. By knowing the ability of different cultivars to compensate for the different yield components and knowing which yield component that is the most important for the final yield, the farmer can match the cultivar and management to the location. The objective of the study was to investigate how the yield components of winter wheat vary depending on genotype, environment, sowing density and date of sowing.Seven varieties were grown in four locations in Sweden with three different sowing densities and with an early and a late sowing date. On each experimental site, the surviving plants after winter were counted, as well as the number of shoots at early and late spring and the number of ears. Ten ears from each site were cut at three different occasions, starting from the time of blooming, with 200 day degrees between each cut.

Analys av off-design prestanda för ett absorptionskylsystem

This master thesis project at KTH is performed in the Mechanical and Aerospace Engineeringdepartment at University of Florida (UF). The thesis is a small part of a gas turbine researchproject where a vapour absorption refrigeration system (VARS) and a high pressure regenerativeturbine engine (HPRTE) are integrated together. The main objective is to build a computermodel of the VARS. The computer model is supposed to be used to analyse the off-designperformance of the VARS and should also be easy to integrate as a subroutine in a more complexsystem model. To model the VARS some knowledge of the absorbent/refrigerant mixture had tobe well known, in this case a mixture of ammonia and water.

Betydelsen av biologiska aktivitets- och experimentmaterial i förskolan

The purpose of this study was to gain greater knowledge of how preschool teachers and children using an experimental- and activity box in biology. To find this out, I have used the participant observation method and semi-structured interviews since my study is qualitative. The result of the work led to a greater understanding of the biologybox. It was shown that preschool teachers' involvement is very important for children and that the biologybox contained good and inspiring materials. Although educators desired that there was more material to choose from as well as the usage time of the biologybox should be longer than 3 weeks..

Effekter av gödsling i äldre tallbestånd på renbetesväxter i fält- och bottenskikt :

Reindeer husbandry and Forestry are both area related industries and will in big extent use the same lands. Conflicts often arise because of that the industries have different interests. Many of the activities done by the forestry influences the reindeer husbandry in an undesirable way, simultaneously as the reindeer husbandry activities can have negative consequences for the forestry. One such forestry activity is fertilization. It was during the 1960´s forest fertilization began to be practiced and the reason was that the increase in growth that the fertilization gave could be able to cover for the future shortage in wood many feared. During the 1970´s when the fertilizing activities were most intensive about 200 000 ha was fertilized annually.

En jämförande undersökning om förloppet vid terapeutiskt utförd KAT-töjning och statisk egentöjning: Single Subject Experimental Design

Bakgrund: En stram muskel kan orsaka ett försämrat rörelsemönster som i sin tur kan vara orsaken till skada, detta kan dock motverkas genom stretching (töjning). Syfte: Syftet med studien var att undersöka hur och om rörelseökning i hamstringsmuskulaturen skedde genom töjning med KAT-metoden respektive statisk töjning under en töjningsperiod på tre veckor. Metod: Förloppet kring stretching av hamstringsmuskulaturen undersöktes genom töjning varannan dag under 10 interventionstillfällen. Studien genomfördes som en Single-Subject Experimental Design (SSED). Baseline och withdrawalmätningar grundlades där inga töjningar utfördes.

Local poultry production in rural Zambia and the effect of light on poultry performance

Zambia is a country in Southern Africa where poverty is widespread and the traditional keeping of local poultry therefore plays a crucial role in improving nutrition. Meat and eggs from poultry are important sources of protein but also of income. Improving the poultry production is thereby a method to fight poverty. For poultry, the access to light is an important factor for both growth and egg production. In this paper, the focus is on the traditional village chickens used for both egg and meat production, how they are kept, their health and welfare and if the use of a solar lamp will influence their behaviour, growth and egg production. Three studies were conducted in Chibombo and Choma Districts in Zambia were 17 farmers were interviewed regarding the village chicken management of which six farmers participated in a solar lamp experiment.

Ventral Töjning Pectoralt (VTP) som behandlingsmetod vid ett avvikande hållningsmönster i nacke och axlar : Single Subject Experimental Design

De senaste årtiondenas explosionsartade teknologiska utveckling har gett oss möjlighet till en mer stillasittande och inaktiv livsstil framför skärmbundna aktiviteter som datorer, surfplattor och smartphones. Det leder till en avvikande hållning. En avvikande hållning i nacke och axlar definieras som ökat framskjutet huvud, ökad thorakal kyfos samt protraherade (framskjutna) axlar. Genom ökad aktiv eller passiv tension av pectoralis minor har forskare antytt att det kan påverka skuldrans kinematik för individer med nack- och skuldersmärta. Syftet med studien var att utvärdera om töjning av pectoralis minor med behandlingsmetoden Ventral Töjning Pectoralt (VTP) har någon inverkan på individens avvikande hållning genom korrigering av axlarnas och nackens position.
