Predatorinducerad fekunditet hos Daphnia pulex vid simulerade årstidsbundna temperaturvariationer

Female growth, number of eggs and egg growth of Daphnia pulex were studied at four temperatures, 12, 16, 18 and 20°C. I hypothesized that female growth and number of eggs would be lower and the size of the eggs larger in the presence of a predator (kairomones) than in its absence. This effect was expected to be more evident at lower temperatures. I could not find any effect of kairomones on female growth, number of eggs or egg size, although there was a weak tendency for an effect on number of eggs. There was, however, an effect of temperature, regardless of predator treatment (i.

Dekonversion och självuppfattning : En religionspsykologisk studie av dekonvertiters berättelser

This study focuses on aspects of cult experiences, given by deconverted formermembers of closed religious movements. Their testimonies were published inbooks or interviews. The aims of the study were to understand the interactionbetween the religious group and its members, living in high tension towardsmainstream society and their testimonies of altered self-esteem during attraction,membership, deconversion and defection. The purpose was to understand how aperson´s self-esteem is affected by inner mechanisms of closed religiousmovements and how these experiences affects a persons identity. Another aspectwas whether there might be differences in altered self-esteem, between those whoenlisted as adults, and those who were born into the closed religious contexts.Social Identity Theory, Sigmund Freud´s and Carl Rogers models of personal egowere used as models of interpretations.

Inverkan av den genetiska defekten Complex Vertebral Malformation på fruktsamheten hos SLB :

Complex Vertebral Malformation (CVM) is an autosomal recessive inherited defect in the Holstein breed. The defect has lead to structurally malformed calves and losses of pregnancies. To determine the effect of CVM on fertility in the Swedish Holstein Breed 375 Holstein bulls used in breeding by Svensk Avel and Skånesemin were assigned to this study. 228 bulls matched the criteria of birth year, 1995-1999, > 75 inseminations and a known CVM-status. Of the total 228 bulls 53 of them were CVM-carriers and 175 were non-carriers. The SAS-programme was used to determine the effects of CVM-status, the bull?s father and birth year on Non-return rates (NRR) for 28, 56 and 168 days.

Inverkan av foders växtöstrogener på fysiologiska processer hos produktions- och sällskapsdjur

Phytoestrogens are secondary metabolites produced by plants. Among the plants that make phytoestrogens are soya, red clover and some types of grass. The name phytoestrogen is a collective term for compounds such as genistein, daidzein, biochanin A and formononetin. These compounds are similar to oestradiol-17? in their chemical structure.

Indexeffekten : En studie gjord på Nasdaq OMXS30 och OMXH25

AbstractMaster thesis in Business Administration, School of Business and Economics at Linneaus UniversityAuthors: Patrik Larsson and Pontus GislénSupervisor: Håkan LockingExaminer: Sven-Olof CollinTitle: The index effect- a study on Nasdaq OMXS30 and OMXH25Introduction: A significant part of the financial literature is based on the Efficient Market Hypothesis which assumes that prices in the market reflects all available information. Anomalies, such as the index effect, indicate weaknesses in this theory as it has been proved that it is possible to outperform the market using public information. Hence, the index effect can be linked to market efficiency which makes it interesting to study from a theoretical perspective. The mapping of the index effect is also interesting from a practical perspective, as it leads to a better understanding of whether investors and firms should take this anomaly into account.Problem: Is there an index effect, how does it behave and what can explain this effect?Purpose: The aim of this study is to investigate the index effect.

Dexametasons effekt på trombocytaggregering och syreradikalproduktion

Platelets are important for the healing of damaged blood vessels since they have an importantpart to play in the coagulation process. At the same time, the blood must be kept fluid and notcoagulate at the wrong time. Therefore there are factors that effect the aggregation of plateletsin a positive or a negative way.Previous investigations have shown that platelets during stirring conditions produce reactiveoxygen species (ROS) that weaken the inhibiting effect of nitric oxides (NO) on platelets andthat the drug Dexamethasone (Dex) can reduce the ROS-production.The aim of this project was to investigate if glucocorticoids, in this case Dexamethasone,could restore the inhibiting effect of NO on platelets and if there was any decrease in ROS-production.The result of the ROS-measurements showed a great variance and it was difficult to draw anyconclusions from them, but a clear decrease in ROS, as previous reported, was not shown. In the aggregation experiments the inhibiting effect of NO was observed through the drug S-nitroso-N-acetylpenicillamine (SNAP), a NO-donator.From the aggregation experiments, the result seemed to be that SNAP during longerincubation time lost its inhibiting effect, probably because the cells become desensitized.With superoxid dismutase (SOD), the effect of SNAP increased, both in the experiment withlonger and shorter incubation times. Dex seemed to reinforce the aggregation in relation toboth SOD and SNAP.

Alkoholvanor inom det gymnasiala fordonsprogrammet

The consumption of alcohol in Sweden has increased considerably within recent years. Among youths there has been a tendency towards drinking more frequently and increased volumes. Alcohol habits among students on the high schools auto mechanic line has been given a questionnaire to examine their experience of the immediate after effect of alcohol and how et effects their situation in school. It has been proven that participating students are drinking alcohol more frequently than the average among Swedish high school students and girls more often than boys. The general experiences of alcohol after effect are predominantly negative both physically and psychologically, but the students are not concerned of their alcohol habits having an effect on their school work..

Valet av Renegade och Paragon i Mass Effect : Undersökning av möjliga aspekter på valet att spela som ond eller god med fokus på spelarens subjektiva upplevelse

The purpose of the study was to examine possible aspects concerning the choice to play as good or evil with a focus on the players´ subjective experience. A form was constructed and the material was interpreted according to Interpretative Phenomenological Analysis (IPA). The games Mass Effect I and II were used as an example of the choice to play as good or evil since the choice between Renegade (evil) and Paragon (good) is present. The sample consisted of individuals who had played Mass Effect I and/or Mass Effect II and were over 18 years old. The end result concerning who played a Renegade or a Paragon came to be very uneven (15 out of 16 participants played a Paragon) which means that the result mostly relates to possible aspects concerning the choice to play a Paragon.

Al Gore may have helped put global warming on the agenda. However, it is not a new subject. Neither is so called green marketing a new phenomenon within branding and communication.
