Vänner med förmåner : positiva effekter av interaktion mellan människa-hund

The aim of this review was to examine scientific literature to determine what kind of physiological and psychological benefits derive from human-dog interaction, as well as attempt to uncover a possible mechanism behind these benefits and whether or not they are mutually beneficial. A growing body of research indicates there are physiological and psychological benefits associated with human-dog interaction. Significant cardiovascular benefits have been linked with human-dog interaction, as have lowered blood pressure, cortisol and heart rate. Interaction with dogs is often associated with a feeling of social support and well-being, and dogs also seem to facilitate social interaction between people. Dogs? ability to buffer and reduce stress is also well documented. A strong indication was found regarding a relationship between physical contact and benefits associated with human-dog interaction.

Marktäckande, lågväxt vegetation på ställverksmark : en biologisk bekämpningsmetod mot ogräs

Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation. Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.

Uppbyggnad och reglering av en pumpstation till ett injektionssystem

I was assigned to the thesis as part of a project GMA AB (Ground Machinery Applications AB) is running. The project aims to develop a new method for injection of drilled holes in rock walls. Currently, the injections usually involve cement but the basic idea of the project is to replace cement with a supplement called Silica sol.Silica sol is known as a gelling liquid. The gel time is controlled by a mixing of saline. Depending on the amount saline that gets mixed in, the gel time varies.

High Cereal Prices : An analysis of the causes behind the increase in the world market price of corn, rice and wheat.

The purpose of this study is to examine which factors played an important role in the food price crisis of 2007-2008. Theories used are Microeconomic theory, explaining changes in supply and demand, and Macroeconomic theory, explaining the impact of changes in exchange rate on prices. A theory regarding speculation is also used to explain the impact of speculative activities effects on price. The method used is multiple regression analysis in order to determine the effects which ethanol production, oil price and dollar exchange rate had on the surge in the price of corn, rice and wheat.The data used is in monthly observations during the period 2005-2008. However, other factors are taken into consideration during the study, such as production quantity, stock size, economic growth, speculative activity and population growth.

SYNS VI I SVERIGE? : En rättssäkerhetsstudie om barn i migrationsprocessen

The current thesis is on the rule of law and how the principles of the rule of law are met in thenew Swedish migration process. The migration process has been subjected to criticism duringseveral years and on different occasions. The migrations process is viewed through a ?rightsof the child? perspective, foremost to seek if the rights of the child are met. The children are avulnerable group, not the least in the process of migration.

Indirekt blodtrycksmätning hos hund och katt :

The objective of this study was to study the agreement between two methods of indirect bloodpressure measurement in dogs and cats and to establish the within-method variation for the methods. The utility and practicality in the clinical setting were also evaluated for the both methods. The techniques evaluated were the oscillometric method and the Doppler ultrasonographic method. Thirtytwo dogs and 26 cats were used in the study and seven dogs and five cats out of these animals had diseases that may effect the bloodpressure. Bloodpressure was measured in both anesthetized and in conscious animals.

Design av utomhusträdgård i Dubai :

To plan and build a garden in Dubai has other conditions and challenges than what you experience in Sweden. The heat, wind and lack of water makes the need for durable plants, a good design and landscaping important if you want to have the opportunity to use your garden during most of the year. The soil is poor of nutrients, alkaline and sometimes saline, witch makes supplying the soil with organic material and various fertilizers necessary if you want to be able to plant a bigger range of plant material in your garden. Another important part is to provide your garden with a good irrigation system that should be put into the ground before planting so that the plants are given a more even irrigation. It?s relatively green scenery you meet and to me it?s in a way surprising since the country with its climate is rather harsh for the purpose of supporting plant life.

Ammoniakförluster vid flytgödselhantering : myllning och surgörning som metoder för att minska avgång vid spridning

The ammonia emissions are an environmental issue since they contribute to eutrophication. By far the largest source of ammonia emissions is manure from agriculture and should therefore be reduced. Loss of ammonia is not only negative for the environment but also to the farmer who loses nitrogen that could have been used by the crop. The focus of this study has been emissions from spreading slurry where the loss can vary widely depending on slurry-, soil-, and weather conditions. There are mainly two different ways to reduce the emissions. One is to inject or mix the slurry into the ground to avoid air contact. The other way is to use acid to reduce the pH in the slurry to a level between 5 and 6 where the equilibrium is so strongly pushed to NH4+ that hardly any NH3 can be lost.

Alkoholmissbruk på arbetsplatsen -När är det grund för uppsägning?

Abuse of alcohol is one of the biggest problems that society faces today. There are between three and four hundred thousand abusers in Sweden. In addition there are about three hundred thousand over consumers. The government bill proposed in 1977 gave the labour market most of the responsibility to solve the problem. They thought a meaningful job and a spirit of community were the most important factors to decrease abuse of alcohol and social rejection.

Folkligt deltagande & regional utveckling

The residential yard at Kvarteret Landsfiskalen 1, in the area Herrgården in Rosengård, Malmö was built in 1971 and has since then been reconstructed twice, in 1984 and 2008. The yard is found in an area which was built during the years 1965 ? 1974, a period in which the swedish goverment approved a decision to build one million homes, and much of the events in this particular yard is also typical for the process in many other areas built during the same period.At the original construction the design of the yard was entirely incused by the pressure in time and finance, one was under at that time, in order to over- come the housing shortage. The design it has nevertheless been given, reflects the esthetic ideals of that time well.The building of the area was barely finished when the swedish authori- ties started handing out grants in order to support the rearmament of the outdoor environment in the areas built during the so called ?million program?.

Normativa data för samband mellan subglottalt tryck och ljudtrycksnivå

Syftet med föreliggande studie var att undersöka sambandet mellan subglottalt tryck och ljudtrycksnivå, och undersöka inverkan av kön och tonhöjd. Röststyrkan är starkt beroende av subglottalt tryck och sambandet har analyserats i ett flertal studier, som alla visar på ett linjärt förhållande mellan logaritmen av subglottala trycket och ljudtrycksnivån (SPL). Schutte (1980) analyserade sambandet för 21 kvinnor och  24 män som producerade ett stort antal mätdata med olika SPL och tonhöjd. Tryck mättes med ballong i esofagus. Tanaka & Gould (1982) analyserade 4 kvinnor och 6 män på tre ljudnivåer på bekväm tonhöjd; svag, normal och stark ljudstyrka.

Working Veterinary Nurses and Veterinarians have been surveyed to find out what they think the responsibilities and education of the Registred Veterinary Nurse should be..

Vedlevande lavar på döda grenar på levande träd i produktionsskog

Saproxylic lichens in managed forests have less substrate available than in unmanaged forests due to the shortage of dead wood. However, a suitable substrate for these lichens could be dead branches on living trees. To this date, there has not been any systematically collected data about theabundance of dead branches on living trees and the lichens growing on these branches in managed forests. The aim of this study was to see where dead branches were located on living trees of Pinus sylvestris and Picea abies, how large the surface area of these branches was and what lichens grewof wood on these branches. The study was made in Finspång, Sweden, where 11 forest stands of P.sylvestris and P.

A systematic review.Author: Josefine Lindqvist, Robin Järnmark, Mathilde OhlinSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2014-04-09BackgroundResearch indicates that dairy products seems to have a protective impact on the incidence of cardiovascular disease regardless fat content. Paradoxically the Nordic nutrition recommendations recommend an exchange of full fat dairy product to low-fat dairy products.ObjectiveThe aim of this review is to investigate whether the variation in fat content of dairy products have any bearing on the onset of cardiovascular disease. With regard to common risk markers for cardiovascular disease the outcome measures hypertension, hyperlipidemia and weight gain is examined.Search strategyThe searches were made in the databases Medline (23/1-14) and Scopus (6/2-14).Selection criteriaRestrictions: Human Studies, Adults, Randomized Controlled Trials, English.Data collection and analysisTwo RCTs were included. Validation of the separate studies was performed with SBU's review template for individual studies and GRADE was used for summarizing the evidence of outcome measuresMain resultsThe two included studies examined the outcome measures blood pressure, weight and blood lipids.

Framtagandet av ett företags visuella produktidentitet

Aqeri has since the past year a new profile with name and logotype, which has createda need for an updated visual product identity. The company is a leading developer,producer and distributer of IT products suitable for extreme environments in industry,defense and vehicles. This new profile with the different segments has together with aproduct identity from two companies resulted in that they have no clear designidentity on their products. From this background the aim of this research is todetermine how a development of a design identity is done to implement it to Aqeri.The design identity can be defined as a product?s identity visualized through its formor appearance which defines what the product is.
