Fredningseffekter och rekryteringsproblem hos abborre (Perca fluviatilis) i Stockholms skärgård
Effects of fishery closure on perch was detected as female perch was on average 5 cm longer in closed areas compared to non-closed areas. This could be a result of larger individuals surviving as an effect of reduced fishing. No effect was detected on the reproduction rate of YOY (young of the year) perch.A zooplankton survey revealed less amounts of the most important plankton groups for YOY perch in areas with failed reproduction, though the difference was statistically insignificant.The distribution of YOY perch and YOY/adult stickleback differed completely in this study with no area where the two species are both present. It is sketchy to draw any conclusions from this data but it remains a field for further investigation.The reproduction problem is concentrated to the outer parts of the archipelago which confirms previous studies of the geographic extension..
Effects of koccidiae- and nematode infections in first-year grazing calves :
Twenty-four calves, which had not grazed previously, were divided into four groups. They were subsequently inoculated orally with either E. alabamensis oocysts, O.ostertagi/C. oncophora larvae, or both. One group remained uninfected and was used as a control.
Kreativ produktexponering inom e-handeln
This study investigates whether creative online product exposure within the clothing industry has a positive effect on the behaviour and attitude of today's consumers. Product exposure is the most important stimulus in the online marketing universe, yet few studies exist on this topic. Thus, this study pioneers in this specific research field. Through empirical analysis this study reveals that product exposure has a significant and direct effect on the perceived corporate ability and consumer involvement. Moreover creative product exposure indirectly increases the perceived product quality, intention to buy and the overall attitude towards the brand.
Vägen till produktionsanpassade arbetsinstruktioner
The purpose of this thesis was to investigate the need of working instructions in Derome Träteknik ?s industrial house-building factories. Furthermore we wanted to determine an appropriate way for developing working instructions adapted to the conditions in a certain production environment. In the construction industry today prefabricated building elements are frequently used. With this come repetitive work tasks that need to be carefully planned.
Kontokortsbaserade betalningssystem på Internet
Internationally most Internet trade related payments are performed with the use of a credit card based payment system on the Internet. Payment against invoice is still most common when trading over the Internet in Sweden. The security development, comfort and timesaving indicate that credit card based payment systems on the Internet soon will have a breakthrough in Sweden as well. The Swedish legislation concerning payment is neither especially extensive nor suited to electronic payments but to payments performed with notes and coins. When the legal effects, of a payment performed with a credit card based payment system on the Internet, set in is not fixed.

Marknadsanpassning : hot eller möjlighet?
Making the work in the public sector more efficient is something that has been seen as necessary during the later years. One way to do this on municipal level has been to apply solutions former used mostly by private companies. The organisational parts have also been adjusted to existing conditions in this work of change. For example more and more municipalities have come to use the purchaser-supplier model since the beginning of the 1990's. Norrköping, Linköping and Motala have been chosen in this essay for a closer study of the effects of the changes of the 90's, from an efficiency point of view.
Förstå kundens bruksvärde
Abstract?Understand the customers value in use ? A multiple case study of three industrial companies? or ?Förstå kundens bruksvärde ? En multipel fallstudie av tre industriella företag? brings out the problem that it is easy to assume, what the value is for the customer.The questions asked for this thesis are:? How does the companies in focus, gather information about what effects the customers value in use?? How do the companies use this information in their business?The purpose is to examine how some industrial companies gather information about the customer?s value in use, on the bases from the five activities from Porter and how they can use this information.Three semi structured interviews were made for this investigation, with representatives from Atlas Copco Rock Drills, IL Recycling and Johnson Pump.The conclusions are that to gather information about the customers value in use, the company must work close with the customer. This information helps the company to improve their products, services and their relationships..
Direkta effekter av insekticiden deltametrin på zooplankton och bottenfauna : en fältstudie av bieffekter av insekticidinducerad eliminering av signalkräfta på Gotland
Direct effects of the insecticide deltamethrin on zooplankton and benthic invertebrates werestudied during an attempt to eradicate signal crayfish. In accordance with earlier studies theresults of this investigation showed that deltamethrin is highly toxic for arthropods, whileRotifera, Oligochaeta and Mollusca have a higher tolerance. This study concludes thatRotifera in treated ponds coped with the actual concentration of deltamethrin used during theeradication attempt but that they probably got a different abundance and changed compositiondue to a new situation in competition and predation. Crustacean zooplankton totallydisappeared, but approximately a month after the treatment they began to recolonise. All thetaxonomical groups of arthropods drastically decreased in abundance, with total eliminationof the most sensitive groups.
Kan omega-3 lindra hudsymtom hos psoriatiker?
Sahlgrenska Academyat University of GothenburgDepartment of internal medicine and clinical nutritionAbstractTitle: Does omega-3 mitigate skin symptoms in psoriatic patients? ? A systematic review about the effects of supplementationAuthor: Anita Borgmästars and Sara LinderSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 22, 2012Background: Psoriasis is an inflammatory skin disease with high prevalency. Its treatment is time-consuming and associated with many side effects. Therefore alternative forms of treatment, among them omega-3 supplementation, have been investigated. Omega-3 is a family of polyunsaturated fatty acids whose metabolites participate in the regulation of inflammatory reactions in tissues and may therefore have a positive effect on skin symptoms in patients with psoriasis.Objective: To determine if omega-3 supplementation has a beneficial effect on skin symptoms in psoriasis compared to omega-6 supplementation by rating the evidence quality in available studies.Search strategy: The literature search was conducted in the databases PubMed, Scopus and Amed.

Demonstrationsprojektets roll i framväxten av ny teknik: Fallstudier av två vindkraftprojekt
This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.
Kan kombinationsbehandling med liotyronin och levotyroxin ge positiva effekter hos patienter med hypotyreos?
Bakgrund: Sköldkörteln är en endokrin körtel som tillverkar två viktiga hormon som påverkar många olika organ, tyroxin (T4) och trijodtyronin (T3) som är det mest aktiva. Det tillstånd då det bildas för lite sköldkörtelhormon jämfört med vad kroppen kräver kallas hypotyreos och hypotyreos kan vara svår att känna igen på grund av en skiftande symptombild. Syntetiskt T4, levotyroxin, är förstahandsval vid behandling. Trots tillräcklig dosering av levotyroxin, har patienter visats ha minskat psykologisk välbefinnande och minskad neurokognitiv funktion. I enstaka fall, när patienten inte mår bra trots att proverna ser bra ut, kan tillägg av L-T3 prövas.
Vilka faktorer påverkar företags kassahållning?: En studie av svenska börsbolag 1999 - 2009
This paper investigates the determinants of corporate cash holdings for a broad sample of Swedish non-financial firms in the 1999 - 2009 period. Using a fixed effect regression model, we find that firms with riskier cash flow hold relatively high ratios of cash to total assets. This is in line with both the precautionary motive and agency motive for cash holdings. Net working capital is found to be negatively related to corporate cash holdings. A result commonly interpreted as support for a negative substitution effect between net working capital and cash.
Att styra eller leda - En studie av rollfördelningen mellan styrelse och VD i strategiutvecklingen i svenska börsnoterade företag
Who has the ownership of a company´s long-term strategy, and who should have it? Is it the board of directors or the senior management? Swedish law and regulations seemingly point in one direction, whereas the findings of studying the relationship between CEO and chairman of the board in eleven Swedish listed large- and mid-cap companies, point the other way. In a majority of the companies the senior management have the ownership of the long term strategy whilst the board of directors merely hold a control function. The possible effects on the companies managed as well as the rules and regulations they are managed according to, are analyzed..
