Utvärdering av Central Tire Inflation på Medelpads skogsförvaltning, SCA Skog AB
CTI- Central Tire Inflation är ett styr- och reglersystem som möjliggör att justera lufttrycket i däcken under färd på virkeslastbilar för att anpassa det till aktuell last och hastighet. Genom att köra med ett lägre däcktryck på virkesfordon är det möjligt att minska kostnaden för skogsbilvägar.
SCA Skog vill skapa en CTI-strategi som ska innehålla handlingsplaner för hela kedjan från planering till transport. År 2009 minskade investeringsanslagen för vägar inom SCA Skog och Medelpads skogsförvaltning började bygga vägar som trafikeras av CTI-utrustade fordon. Syftet med arbetet är att utvärdera användningen av CTI åt SCA skog vid Medelpads skogsförvaltning.
Datainsamlingen utgjordes av intervjuer med personer vid SCA som har arbetat med CTI någon gång sedan införandet. Totalt intervjuades elva personer.
Ett arbetssätt för CTI identifierades.
Projektering av ett småhus samt ekonomisk jämförelse av värmesystem
Design of a house requires knowledge of both technology and economics. Heating and ventilation shall be designed, costs are calculated and estimated and requirements must be fulfilled. Which heating system is to be elected is also a difficult choice, especially with rising energy prices as a factor.The choice of energy system is not always given, because it depends on several factors. Below is a comparison between district heating, geothermal heat pump and electric boiler from an economic standpoint. In a previous report appears district heating and geothermal heat pump as the best options.
Vad påverkar beslutet av missbruksvård? : Faktorer som kan påverka val av insats
Title:What influences the assessment of addiction treatment? - Factors that may affect thechoice of interventionsThere are few studies on trauma and the importance of religion for the professional handlingof abuse clients in a Swedish context. It is therefore appropriate to examine the role of suchfactors. This study examines whether experienced trauma in childhood or religious beliefsinfluence the assessment and selection of input in fictitious cases. To examine this created sixvignettes.
Deltidsarbete bland kvinnor i Sverige - vad påverkar val av arbetstid?
English title: Part-time work among women in Sweden ? what influences choice of working hours? In the 1960s and 70s a large growth in part-time work amongst women in the Swedish labour market took place. A net inflow of workers into the labour market has been suggested as the main source. However, part-time work is still a common phenomenon among Swedish women; in 2004 almost 40% of all women worked part-time, and women are clearly dominating the part-time sector. A gradual changeover from house work to market work is hardly a valid explanation anymore.
Gips : Miljöproblem eller resurs?
Avfall i stort har fått en annan innebörd i dag jämfört med tidigare decennier i och med att det nu går att återanvända, återvinna och utvinna energi ur det. Gips är ett avfall som förekommer som brandskydd i stor omfattning och förut gick majoriteten på deponi. Nya alternativ har dykt upp det är dock fortfarande mycket som går på deponi och det medför miljöproblem, främst i form av läckage av svavel.Syftet med studien var att genom telefonintervjuer se hur hanteringen av gipsavfall uppfattas av aktörer inom byggbranschen, hantering och transport av avfall och olika återvinningscentraler. Men även att se vilka miljörisker de olika aktörerna anser att gipsavfall kan leda till. De aktörer som intervjuades var inom området bygg; NCC, inom området hantering och transport av avfall; Sita och Ragn-Sells, inom området återvinningscentraler; en återvinningscentral från Uppsala och en från Malmö.Slutsatsen blev att aktörerna först och främst försöker återvinna gipset, går inte det är det deponering som är det sätt varpå gipsavfall hanteras.
Comparison between different freezing and thawing methods for human spermatozoa
Preservation of cells and tissues by freezing at temperatures below 70°C has led to new possibilities for the storage of germ cells for fertility preservation. During the freezing process problems might occur, the greatest being ice crystallization which can cause membrane destruction and thus cell death. To minimize this risk, solutions that reduce the freezing point can be added to reduce crystallization and increase survival rates. These solutions are called cryoprotectants. The best method for freezing is still not known.The aim of this study was to analyze the effect of various parameters on the survival rate of human semen frozen with liquid nitrogen.
Fältskiktsarter i naturlika planteringar : vilka råd kan ekologer ge?
This paper appeals to professionals working with green questions. It intends to create a discussion about which plant species that can be established in a fieldlayer of a naturelike planting on fertile agricultural land. To initiate the essay, a studie of which values that can be connected with an establishment of a fieldlayer was performed . A part of Tor Nitzelius Park in Alnarp, a so called naturlike planting on fertile agricultural land, was used as a model for the choice of species. With the aid of soil values, photos and a list of current species, interviews with four ecologists were performed.
E-tjänstutveckling ur ett medborgarperspektiv : Att skapa beslutsunderlag baserat på medborgarärendens lämplighet för olika kommunikationskanaler
Citizens? interaction with governments is an area with unique implications for channel management. Governments need to take the citizens perspective into further consideration in order to be successful in delivering high-quality e-services. This paper aims to determine if a categorization of citizen-initiated contacts from a citizen-centric perspective can be a valuable basis for decisions regarding e-service development. The study consisted of three steps.
A Chicken and Egg Question : En jämförelsestudie mellan Stockholms skärgård och de grekiska Kykladernas infrastrukturella utveckling, ur ett turismperspektiv
Denna uppsats avser att jämföra den infrastrukturella utvecklingen mellan Stockholms skärgård och de grekiska Kykladerna. Syftet är att undersöka hur viktig infrastrukturen, med fokus på transport, är för en destinations utveckling. Uppsatsen grundas på idén om att Stockholms skärgård inte lyckats utvecklats till en lika självklar destination som Kykladerna, trots den liknande geografiska strukturen. Vi satte oss in i ämnet genom att dels studera tidigare forskning och dels genom att utföra ett antal ?elitintervjuer?.
?Jag är inte kurator, psykolog eller pappa till alla barn, jag är inte bilmekaniker heller? : En studie om idrottslärares yrkesetiska dilemman
AimThe compulsory school attendance in Sweden means that all children are obligated to go to school. This makes great demands on those who work in the school, especially the teachers. Schools are complex units. In school, teachers face all kinds of ethical dilemmas on a daily basis. The aim of the study is to enlighten how different teachers would act differently, if they were facing the same dilemma in the PE-lessons and why this knowledge is important to our profession.MethodThe data was collected through interviews to make a qualitative research.
Cryopreservation of Oocytes : Comparison between the Cryoloop and the Cryopette vitrification techniques
Crypreservation of oocytes is recently being considered to be a valid choice in infertility treatments.Low survival and fertilization rates due to inefficient slow freeze protocols have been the outcome ofmany previous studies done in the field. However, introduction of the vitrification technique and itsapplication in reproductive medicine and to some extent new improved slow freeze protocols haveshown that oocytes can be cryopreserved with successful outcome.In this project the survival rate of oocytes after vitrification with MediCult Vitrification andWarming Media has been studied. Also, a comparison of the carriers Cryoloop (an open system) andCryopette (a closed system) has been performed.A total of 43 oocytes were vitrified and warmed according to MediCult's protocol, of which 21oocytes with Cryoloop and 22 with Cryopette. The cells were post-thaw incubated in a physiologicalenvironment for 24h. During that time the morphology and viability were observed and noted after 2h,over night and after 24h.

Jämställdhet i förskolans verksamhet : En observationsstudie om hur pedagoger förhåller sig till flickor och pojkar ur ett könsperspektiv
The purpose of this study is to look into if the pedagogues who participate in this study treat children differently depending on their sex. The purpose was then divided in three research questions which were: Attention: How much verbal attention and eye contact with the pedagogue are girls/boys getting? Choice of words: Are there any differences in the choice of words the pedagogues are using against girls/boys? Address: How does the pedagogue address girls/boys, are there any differences? The tone of the voice and how the pedagogue address girls/boys belongs in this category. The study was observed with video camera in four different circle time situations, two circle times for each preschool. Data were then analyzed with an observation schedule based on the three research questions.
Socialtjänstens arbete med pojkar som begått sexuella övergrepp
The aim of this study is to examine how one can understand the experiences that social workers within the social service's have of children who have committed sexual assault against other children, and the social workers? thoughts about the choice of actions and the family involvement in those actions. The study has a qualitative character. Information was obtained through interviews with social workers within two Swedish counties, and the analysis of the results was based on earlier research findings as well as theoretical aspects, such as systemic theory and salutogenesis.Regarding the actions taken for the target group, the social workers have, in many ways, a systemic perspective as they emphasize elements within the child as well as within the family. It is also shown that the collaboration with other authorities affects the choice of actions, and that it is important to involve the entire family in any interventions, so that the effect of those interventions may last over time.
