Larvae of Lepidopteran Manduca sexta and Spodoptera littoralis are pests of economical importance in several horticultural and agricultural crops. Knowledge of insect feeding preferences and behavior is crucial in order to find economically and ecologically sustainable solutions to the problems caused by these herbivores. The aim of this thesis was to study the behavior and the induced feeding preferences in larvae of M. sexta and S. littoralis when reared on certain host plants. The hypothesis was that larvae of M. sexta would have an innate preference for plants of the Solanaceae family and therefore discriminate the previously experienced nonhost when faced with the choice between a true host and the previous food source.

The main objective of this study was to evaluate animal welfare situation in Ethiopia during slaughter and to investigate chain activities between animal markets and Kera abattoir in Addis Abeba. In total, 442 animals were observed within 52 groups of cattle; both ox and calves with different breeds. The study was divided into four different sets of data collection; behavioural observations, recording of slaughter process, observation during transport and interview. During the behavioural observations, an ethogram was used with 46 behaviours observed, categorised into 5 different groups. The data was calculated using Excel and SAS. The results indicated that a significant correlation (p-value.

VEP, visual evoked potential is an electrophysiologic test that can be used for evaluating the higher visual pathways. The aim of this study was to investigate if it is possible to adapt this method to horses. This method could have a clinical use in addition to the existing diagnostic methods that are available to evaluate vision in horses. Firstly, this study contains a summary of relevant studies done on animals and, secondly, an experimental part where the possibility of recording VEP in nonsedated and sedated horses is investigated and where to position the recording electrode to obtain the best results. Our results show that it is possible to record VEP in horses in a clinical setting. VEP was best recorded in the sedated horse to avoid movement artifacts and other disturbances.

As a pet owner you are likely to someday face the decision to euthanize your pet and as a veterinarian or veterinary technician you are the one to perform this euthanasia. The reason for euthanasia may be depending on the animal, for instance illness, age and behavioral problems or depending on the needs of the owner or the society, so called convenience euthanasia. Many different euthanasia methods can be used when putting an animal to sleep. The method preferred in animal hospitals is pharmacological euthanasia either by inhalation of anesthetics or by injection of a euthanasia agent. If the pet owner wishes to be present during the procedure it is important to prepare him for what will happen. Many animals are sedated before the euthanasia in order to reduce anxiety and to ensure a softer transition between life and death. The euthanasia agent can then be administrated for instance intravenously or intraperitonealy.

Today?s community requires an increase in food production. Animals are today bred so that they produce more than their ancestors did. Production has been the most important and breeds with the highest production levels have therefore become popular. Many of the old local breeds have become extinct or are about to become extinct because of this trend.

Oilseed rape crops are an important in southern Sweden because of the high intensity of wheat growing. Pollen beetles are the most important pest in oilseed rape and causes often economic losses. Therefore it?s of great importance that we can control the population density, e g by using insecticides if necessary, to avoid mayor yield losses. In year 2000 pollen beetles were numerous in the province of Östergötland. The farmers sprayed with insecticides several times, but with low effects on the beetles. Field trials and laboratory experiments showed that pollen beetles had developed resistance against pyrethroids.

This study was carried out at the Swedish University of Agricultural Sciences, Dept. of Agricultural Research for Northern Sweden. The aim of the study was to determine how plant species richness and diversity influence the nitrogen pools and nitrogen fluxes in the soil. Plant and soil samples from a biodiversity experiment in grasslands were used. Thirty plots with 12 grassland plant species (legumes, grasses, and non-legume herbs), combined from 1-12 species were investigated.

Web 2.0 represents the next generation of creating interactive applications on the Web. The purpose of this thesis was to develop a service tailored to Web 2.0 technology, where users can post ads for free. The platform is an advertising system specially designed for animals. Surveys and interviews have been done; the result is that today?s advertising services on the Internet are not interactive and user-friendly.The users have the possibility to adapt different part of the system to their needs, such as choice of themes.

This report presents a bachelor thesis by Erika Gustrén aimed to increase people?s interest for recycling and reusing by create new products of things that already exist in most people?s homes in the materials textile, plastic and paper. That would be a modern and innovative way to contribute to a better environment.The goal with this project was to create three cocktail dresses made of the same pattern and design and with the three chosen materials. The project did not have its base at a company, therefore an external mentor was chosen to help and support during the development of the project. My mentor was Kerstin Boulogner who is a fashion designer and one of the members of GKF (Gotländska Konsthantverkare och Formgivare) in Visby.The project began with an analysis of the chosen materials; textile, plastic and paper.

Halmstads kommun har sedan två år använt sig av den externa företagshälsovården Previa i beställningsarbetet gällande företagshälsovårdsinsatser och efterfrågar en undersökning av detta beställningsarbete. Syfte: Syftet med denna uppsats är att ur ett verksamhetsteoretiskt perspektiv undersöka beställare och leverantörers beskrivningar av beställarkompetensen av företagshälsovård och att skapa förutsättningar för ett expansivt lärande. Metod: Undersökningen genomfördes genom kvalitativ forskning där en egen metoddesign inspirerad av Change Laboratory och fokusgruppsdiskussioner användes. Två diskussionsträffar genomfördes tillsammans med beställare och leverantörer av företagshälsovård där bland annat motsättningar och positiva aspekter av beställningsarbetet diskuterades. Teoretisk referensram: Beställningsarbetet belystes genom hela studien ur ett CHAT-perspektiv där yttre faktorer ansågs ha betydelse för kvaliteten på beställningsarbetet.

The hybrid larch (Larix x eurolepis Henry) is a fast growing tree species and was introduced in Sweden for about 50 years ago. The high growth and expected resistance to diseases are probably the main reasons of introducing the tree species into the Swedish forests. The purpose of this thesis was to document the production of hybrid larch planted in the Snogeholm landscape laboratory and to compare the production in the pure hybrid larch stand with the mixture together with pedunculate oak (Quercus robur). The data collection in Snogeholm since the establishment has been carried out by the Swedish University of Agricultural Science (SLU). The fieldwork for the thesis was carried out in 3 stands, containing hybrid larch, pedunculate oak and a mixture of hybrid larch and pedunculate oak, in order to be able to compare the total stand production of the areas. The results show that the total production of hybrid larch in the mixed stand only is 35 % compared with the total production of hybrid larch in the pure stand. Therefore, the hypothesis that the total production of hybrid larch is equal to the planted mixture with pedunculate oak was rejected. The other hypothesis that the total production of a 2 hectare large stand containing a mixture of hybrid larch and pedunculate oak would be greater than the total production of two pure stands of 1 hectare containing hybrid larch and oak each was also rejected. In the studied case the total production was 45 % greater if hybrid larch and pedunculate oak was planted in pure stands. The results from the case-study only indicate that the total production of hybrid larch and oak under the investigated conditions can be higher when planting the two species in pure stands compared with a mixture of the two species.

Earlier studies of musculoskeletal problems with milkers working in milking parlour operators have shown that it is a physically demanding occupation. The extremities that are most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in present cases are fishbone and some tandem barns. There have been changes in the working environment during the past ten years. The mechanisation has been developed for the better with automatically removers of the milking units and vertically adjustable floors in almost every daily milking barn. In other hand the milk production are more industrialised and more related to stress today.

There are several different kinds of bacteria that has developed resistance against the antibiotic agents used in todays medicine. Most of them has evolved from the human health care but several of them has gone over to also cause problems in the animal health care. They often occur as nosocomial infections and the greatest risk of exposure to them is during health care. Since infections with a resistant bacterium can be difficult to treat, it is desirable to prevent this spread, especially since an animal treated in a hospital often is more susceptible to infection, due to their primary condition. In Sweden the current resistance situation is good and is yearly monitored by the Swedish Veterinary Antimicrobial Resistance Monitoring (SVARM) programme.

African elephants (Loxodonta Africana) are kept all over the world in different kinds of enclosures. The enclosures are however often unsuitable for the elephants. Research has shown that elephants are nocturnal animals. Therefore it is important to keep elephants occupied, for instance by using enrichments, also at the night. Five elephants were studied at Borås djurpark, four elephants in one room and one elephant, named Nyoka, in one room.

What is located on the bottom in the water outside of Birka? Remains of a water palisade or jetties and other constructions.Birka a Viking Age town that existed between AD 750 and 975 was located on the northwestern part of the small island of Björkö, in the Mälar archipelago of the Baltic Sea in Sweden. The Town was protected onshore by a hill fort and a town rampart. It is a widely spread assumption that Birka had a water palisade as a part of its defense. There are logs and other remnants on the bottom of the lake dating back to the Viking age.
