Bioelectromagnetics for improved crop productivity : an introductory review with pilot study of pre-sowing treatment of tomato
Various electromagnetic (EM) treatments has been investigated for their potential in improving crop productivity over the past century. There is today an increasing amount of scientists advocating EM treatments as an organically compatible method for improving plant
growth and yield. However, failure to produce repeatable effects and defining causal mechanisms has made it a study of much controversy and debate. The subject requires indepth
interdisciplinary knowledge, making it inaccessible for the majority of biologists, horticulturists and growers. In this combined literature review and pilot study, these issues are addressed by providing a comprehensive introductory review of the topic plant
bioelectromagnetics and its potential horticultural usability.
Aktiv förvaltning för högre avkastning? : En jämförelse mellan aktivt förvaltade pensionsfonder och index
Den första januari år 1999 upprättades ett nytt statligt pensionssystem i Sverige. Det gamla systemet ATP ersattes av ett nytt system; den allmänna pensionen. En del av den allmänna pensionen blev premiepensionen. Den delen av den allmänna pensionen är ett fonderat system där pensionsspararen själv kan välja hur det inbetalade pensionskapitalet ska placeras. Idag finns det drygt 800 fonder för pensionsspararna att välja bland till sin premiepension.
Företagsförvärv : En studie om förvärvsmetodens betydelse för de uppköpande företagen
Denna uppsats utgörs av en jämförande studie vars mål var att utröna huruvida åtta stycken utvalda investmentbolag på Stockholmsbörsen hade varit ett konkurrenskraftigt alternativ som sparform eller inte med avseende på risk och avkastning. Detta jämfört med SIX Return Index och den riskfria räntan under en tidsperiod på tio år, 2001-01-01 till 2010-12-31.Syftet med undersökningen var att den i slutändan skulle mynna ut i generella slutsatser kring investmentbolag som sparform utifrån de data som hämtats in från de berörda investmentbolagens hemsidor.Författarna kunde efter avslutad undersökning dra slutsatsen att investmentbolagen historiskt sett hade klarat sig mycket bra och kunnat uppvisa resultat som varken marknaden eller den riskfria räntan var i närheten av. Även om vissa av investmentbolagen hade presterat sämre än jämförelsemåtten så var dock den samlade bilden att de som grupp hade varit ett mycket fördelaktigt investeringsalternativ. Detta med en genomsnittlig totalavkastning som överträffade index med drygt åtta procent. .
Är Socialstyrelsens verktyg för att identifiera ohälsosamma matvanor trubbigt och behöver vässas?
Socialstyrelsen har utformat ett index för ohälsosamma matvanor som är tänkt att användas nationellt inom hälso- och sjukvården. Kostindexet syftar till att identifiera vilka människor som har ohälsosamma matvanor och därför bör erbjudas kvalificerade rådgivande samtal för att få hjälp att förbättra sina matvanor. Studies syfte är att utifrån exempelvis ålder, kön och BMI kartlägga hur populationen inom slutenvården på ett akutsjukhus i södra Sverige besvarade Socialstyrelsens index för ohälsosamma matvanor under en specifik dag. Dessutom undersöks betydelsen av olika komponenter i indexet. Studiedeltagarna besvarade fyra olika enkäter, varav en utgjordes av Socialstyrelsens kostindex.

Hand Arm RiskbedömningsMetod (HARM) : Utvärdering av en metod för riskbedömning av biomekanisk belastning av övre extremiteten vid manuellt arbete samt dess lämplighet vid arbetsmiljötillsyn
AbstractIntroduction: Hand Arm Risk Assessment Method (HARM) is a tool to assess the risks of developing complaints of the arm, neck or shoulders during manual work. The method was developed in the Netherlands primarily for employers, but is also used as an aid to work environment inspectors. The purpose of this study was to evaluate the HARM-method for assessment of biomechanical exposure of the upper limbs when performing manual tasks as well as its suitability to be used within work environment inspection. Methods: Ten labour inspectors conducted assessments of five video-recorded work tasks. Assessments made with HARM were compared with those made with the Assessment of Repetitive Tasks (ART) tool and with ACGIH Hand Actvity Level (HAL) - both methods for assessment of biomechanical exposure of the upper limbs - and with the model for the assessment of repetitive work in the provisions of the Swedish Work Environment Authority on ergonomics for the prevention of musculoskeletal disorders, AFS 1998:1.
Mikrolitografi för rastrerade Gobos
Beacon AB has been producing Gobos for some time. A Gobo is a small round sheet used in projectors almost like a slide. It is used mostly in the commercial and entertainment business. Today these Gobos are created by using a film (also called mask). A digital exposure machine called LIOS has been developed to make it possible to create Gobos using direct exposure.
Hur påverkas aktiemarknaden av räntan, valuta- och obligationsmarknaden? : En empirisk studie under perioden 2005-2009
Introduction: Interplay between all the different subsystems of the financial markets is currently considered as an important internal force in the market. In a financially liberalized economy exchange rate stability is a basis for a wellbeing stock market. If these interactions between all the different subsystems of the financial markets are not detected, this means that there is information inefficiency in the markets.Problem: Can we find any correlation between changes in currency, interest rate and bonds with the stock market index? If so, how do these changes affect the Stockholm Stock Exchange?Purpose: The purpose of this study is to examine if there is any linkage between the interest rate, currency and bonds with the stock market. The researchers wanted to find out how these variables affect the stock market index OMX S30 which consists of the 30 largest companies on the Stockholm Stock Exchange.Method: This research has been based on a quantitative approach.

Mätegenskaper för fruktsamhet och modersegenskaper i fåraveln :
The aim of this literature review was to suggest suitable index traits to use in the Swedish Sheep Recording Scheme for fertility and maternal traits. Since fertility and some of the maternal traits are not normally distributed advanced methodology is needed to calculate genetic parameters. Breeding is a tool to improve the economy of the farm and for the selection of breeders estimated breeding values (EBV) for important traits are of high value. In sheep breeding both lambs born and lambs weaned should be taken into consideration as well as the ewe?s maternal ability, which includes lambing ease, lamb survival, ewe behaviour as mother and the early growth of the lambs.
HAVS ombord - en studie av hand- och armvibrationssyndrom och dess förebyggande åtgärder
On board ships different type of maintenance activities take place. Some of those require working with vibrating handheld tools. Traditionally there is a high awareness of the risks with different type of duties such as protecting the skin from oil or other chemicals, the eyes from splashes and hearing from high noise levels. The experience we have from our time as on-board cadets are that there is less information about vibration hazards available compared to the information concerning other hazards on board.There are threshold values that workers, by law, are not allowed to exceed when working with handheld vibrating tools. The purpose of this study is to investigate how common the use of this type of equipment that can cause damage by vibrations, to the hands and arm amongst the deck crew, and if the crew informed about the risks involved.
Försämras upplevd arbetsförmåga vid ökad ålder bland anställda vid Umeå Universitet
Umeå Universitet är en av Umeås största arbetsgivare med 4200 anställda. Sjuktalen totalt för Universitetet har varit och är fortfarande låga, runt tre procent. Den äldsta åldersklass har dom högsta sjuktalen, med stöd av den informationen beslutades om satsningar på äldre arbetstagare. Universitetshälsan (fhv) fick i uppdrag att erbjuda hälsokontroller, under tre år, till alla anställda som fyller 55 år.Vid hälsokontrollen mättes den upplevda arbetsförmågan med arbetsförmåge index (AFM-index) För att bedöma arbetsförmågan hos undersökta 55-åringar i relation till övriga åldersklasser vid universitetet skickades enkäter med post till tjugofem män och kvinnorfödda ?46, -56 samt ?61.Resultatet av undersökningen visade att upplevda arbetsförmågan låg högre för alla åldersklasser hos båda könen jämfört med den referens som AFM manualen innehåller för jämförbara yrken.
Hållbar utveckling i svensk planeringspraktik : en diskussion kring förtätning och andra ambitioner
If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.
