En analys av sa?ljklimatet i komplexa business-to-business relationer : En utredande nula?gesanalys i kontrast till Insight Selling
The thesis aims to describe the current sales climate in the context of complex sales in business-to-business. The purpose is to increase the clients knowledge of sales and test the clients hypothesis that the sales climate is changing from Solution Selling to Insight Selling, further the thesis aims to contribute to the scientific debate of sales. Solution Selling is characterized, as the name suggest, by selling of solution to the customers needs. With Insight Selling the seller has a provocative approach towards the customer and the seller is searching for customers in the need of change. This is a qualitative study conducted with eight interviews and one focus group.
Stöldskydd
To save energy it?s popular to build houses with low energy loss. In these houses the walls are keeping a lower temperature in the external side which leads to a higher relative humidity. In addition more material, such as wood studs, are used which means that there is more moisture to dry. More moisture in combination with higher relative humidity may pose a higher risk of microbial growth.
Medarbetares uppfattning av säkerhetsklimatet: Skillnader utifrån anställningsår och anställningsform avseende ledningens och arbetsgruppens säkerhetsarbete
Syftet med föreliggande studie var att undersöka om det fanns någon skillnad mellan de som varit anställd få respektive många år samt mellan de som arbetade dagtid och de som arbetade skift gällande uppfattningen av säkerhetsklimatet avseende både ledningen säkerhetsarbete och arbetsgruppens säkerhetsarbete på ett bruk inom massa- och pappersindustrin. Totalt deltog 92 medarbetarna i studien och dessa fick besvara frågeformuläret, Nordic Safety Climate Questionnaire (NOSACQ-50). Resultatet visade att de som arbetat många år uppfattade både ledningens och arbetsgruppens säkerhetsarbete som bättre än de som arbetat få år. Det visade sig även att de som arbetade dagtid uppfattade, om än bara i närheten till signifikant, ledningens säkerhetsarbete bättre än de som arbetade skift. Att ha en förståelse kring att det finns skillnader i uppfattningen av säkerhetsklimatet och vad dessa kan bero på kan vara av vikt för att skapa ett bättre säkerhetsarbete på företaget, något som diskuteras i uppsatsen..
Miljöeffekter av alternativa system för behandling av hushållsavfall i Santiago, Chile : en jämförelse mellan deponering och förbränning med energiutvinning
This report was written by Lisa Bengtson and Hanna Paradis and describes the
degree thesis "Environmental impacts of solid waste treatment in the Metropolitan
Region, Santiago, Chile ? a comparison between current system and incineration
with energy recovery". The purpose of this thesis was to investigate if incineration
with energy recovery could be motivated through an environmental perspective as
an alternative to landfilling of solid waste in Santiago, Chile. The study was
performed with Life Cycle Analysis as a theoretical base.
In Santiago, situated in the thirteenth region of Chile, Región Metropolitana, lives
6,5 million inhabitants. The major part of the solid waste produced in the region is
landfilled on three different sanitary controlled landfills situated outside the city
center.
Insatser och åtgärder för främjandet av laddelbilar i Sverige
To achieve the goal of fossil independency in the Swedish vehicle fleet in 2030, it would be important to substantially increase the proportion of electric vehicles, both BEV:s (Battery Electric Vehicles) and PHEV:s (Plug-in Hybrid Electric Vehicles). The Swedish Energy Agency has funded numerous research and development projects about electric vehicles in recent years. An important task for the Swedish Energy Agency is to allocate state funds to those projects with the greatest potential to contribute to increased establishment of electric vehicles in society.
The purpose of this work is mainly to understand the efforts and measures that can make the market for electric vehicles to grow. The report can contribute to a better understanding of how far the research on electric vehicles has come and what has to be done in the future to promote the establishment of electric vehicles. Another aim for this report is that it should serve as a basis for future decisions by the Swedish Energy Agency on which projects that will be funded with state funds.
Rhododendron och dess skadegörare
Swedish energy policy aims to increase the use of energy from renewable sources and this should be done in a safe, environmentally and sustainable manner. According to the Energy Agency the use bio-fuel increased by 73% between 1990 - 2006. Stands with high share of slash are often located on areas with high productivity which often are located on soils with poor bearing capacity. This will increase traffic on susceptible soil leading to increased ground damage. To reduce the risk of ground damage at slash-forwarding, ground protection is needed.
Rening av lakvatten vid deponin Degermyran i Skellefteå kommun : Utvärdering av nuvarande reningseffekt och simulering av mängden bildat lakvatten under 2000-talets klimatförändringar
At Degermyran landfill, situated in the municipal Skellefteå, a leachate treatment system was installed in 2005. One of the aims of this study was to investigate how well the treatment system works by using data from chemical measurements made on the leachate before and after treatment. Further this study had the purpose of investigating how the predicted climate changes of the 21st century will affect the amount of leachate generated at Degermyran by using a modified version of Thornthwaites water balance model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come.
Viktoptimering av ett kompositchassi till en multimodal lättviktsfarkost
This report describes the master thesis project ?Weight Optimization of a Composite Chassis for a Multimodal Lightweight Vehicle? which is a part of the Master program in Naval Architecture and a part of a research project at the Centre for Naval Architecture, KTH. Demands on smart and energy efficient transport solutions are continuously increasing. In the Stockholm region the citizens are expected to increase with 25% and the road vehicles with 80% until 2030, putting high demands on the traffic system. Using a small multimodal vehicle deals with this problem and uses both the land and waterways for transportation.
Hot och risker med dricksvattenförsörjning : Förutsättningari tid och rum för bevarande av Sundsvalls och Timrås dricksvattenförsörjning
This study describes what impact activity within Wifstas, Matfors,Grönstas and Nolbys water protection areas have on the quality of the drinkingwater. It considers the use of the area, environmentally dangerous activitiesin the past and present, the geology?s part, what harm hydroelectric power damsmay cause if they break and how climate change might affect the area in thefuture. It also takes into consideration activities outside the waterprotection areas which might have a suspected impact on the water quality. Theresults of the study are that pollution from infrastructure such as roads, orwastewater from treatment plants may cause occasional contamination of thedrinking water, foremost due to flooding.

Användarvänlighet i blötutfodring : enkätstudie för smågrisproducenter
It is possible to affect the feed costs in different ways. By steeping or fermentation the digestibility of the feed is improved for the animals with a natural process in the wet feeding system Steeping means that the feed is soaked some hours before feeding. This process activatesenzymes and improves the digestibility of for example phosphorus in the feed and make it more accessible to the animal. Wet feeding can be fermented or not. Fermentationmeans that the feed has been soaked for a certain length of time so that a biological process is started.

Computer Modelling of the Influence of Surface Topography on Water Repellency and a Study on Hydrophobic Paper Surfaces with Partly Controlled Roughness
A computer model based on minimization of the free energy, capable to predict contact angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..
Fuktsäkert byggande : Sjönära bostäder i Östra Hamnen i Västerås
Housing construction very close to the lake Mälaren has become very popular today. One potential problem with these houses is the influence of the sea climate. Unprotected buildings are affected by strong winds and precipitation. So for that reason, it is very important to make an accurate climate investigation and use it for decision-making during the planning of the new settlement.It is very important with a good moisture protection regarding pelting rain, that is the combination of wind and rain. This is more important for buildings close to a lake, as this location normally means a higher exposure to wind.
OTEC-Ett energialternativ för enhållbar ö
Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.
