?Developing a crucial business plan template targeted to Swedish Venture Capitalists?

Objective To study if the Swedish venture capitalists consider business plans in their screening process, and in such case, what aspects they evaluate in order to develop a targeted template for Swedish entrepreneurs. A secondary objective is to describe what other factors Swedish venture capitalists evaluate as a part of their assessment. Methodology The method, which has been used in order to test the objective, has been carried out through extensive literature and article studies, interviews, and distribution of a short and comprehensive questionnaire to a multiplicity of venture capitalists throughout Sweden. Conclusion Generally, the findings of this thesis suggest that a business plan should include elements such as a summary of important elements, a thorough market analysis, financial information, exit strategy, and the risks associated with the project. The empirical material also reveals that venture capitalists also evaluate factors such as ownership influence, the entrepreneur?s industry knowledge, product knowledge and the personal Chemistry in their evaluation process.

"Jag vill vara inspiratör, katalysator" : En studie om kemi i förskolan

Syftet med denna studie var att identifiera hur förskollärarna arbetar med ämnet kemi i förskolan. För att kunna granska detta har kvalitativa intervjuer använts som undersökningsmetod. Undersökningen grundar sig i fem förskollärares berättelser av hur de arbetar med detta ämne. Resultatet visar, efter genomförd analys av intervjuerna, att förskolläraren strävar efter att kemiaktiviteterna bör ske i samspel med andra aktörer i förskolan. Det konkreta arbetet utförs med konkreta verktyg och samtal kring fenomen som förekommer i vardagen.

pH-sensitivity in boreal streams ? the influence of landscape characteristics

The goal of the society to increase the proportion of renewable energy has led to an increased demand of bioenergy e.g. forest biomass. However, there are concerns that removal of biomass will lead to decreased base cation concentrations in the soils and acidification of streams. In order to find in which types of landscape removal of branches and tops could have such negative effects, this study aims to analyse the relations between pH-sensitivity and landscape variables in the Bothnia Bay water district. GIS and digital geographical data were used to analyse the landscape in subcatchments.

Sol, jord och vatten. : Barns tankar om den ekologiska processen

Studies show that the interest and knowledge about science among teenagers is decreasing. They also reveal the difficulties to explain the ecological processes and that the ideas about the nature are collected from everyday life and early school years.The intention of this investigation was to find out more about children?s ideas and knowledge about the ecological processes and to compare these results with the curriculum.The method was a questionnaire and interviews with children in school year 1 ? 6. The aim of the studies was also to find out if any progress connected to age could be found, concerning understanding of the ecological processes.The results showed difficulties in achieving the predestined goals for biology and Chemistry concerning ecology cycles and they differed a lot between the children. Often the learning process showed very little progress.

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.

?Vi är bra på språk och matematik, det nästa är naturvetenskap!? : En studie om arbetet med kemi i förskolan.

Syftet med denna studie är att få större kunskap om NT-projektet, vilket är en kommunalsatsning på naturvetenskap och teknik, och om denna satsning gjort någon skillnad när det kommer till pedagogernas arbete med kemi i kommunens förskolor. Vidare kommer det också undersökas om de som arbetar med NT-projektet har någon särskild utbildning. Detta då det finns intresse att utvärdera NT-projektet och deras ?NT-lådor? samt införskaffa kunskap inom detta område inför framtida arbete inom kommunen ifråga. Kvalitativ- och kvantitativforskningsmetod har använts för att nå fram till frågeställningen.

Sänkta sjöars inverkan på ytvatten i Västerbottens kustland : Samband mellan sänkningsnivåer och vattenkemi i sjöar på sulfidrika sedimentjordar

Lake lowering in sulphide-rich areas is currently a major environmental impact for surface water. This study focuses on whether there is a relationship between a gradient of lake lowering and surface water impacts in areas of sulphide-rich sediments, in order to better understand their contribution of heavy metals and sulfuric acid. Also, is it a reasonable method to use the reduced lake area in order to quantify the gradient? The survey was conducted by collecting water samples from reference lakes and lowered lakes from south to north in coastal areas within the county of Västerbotten. Water samples were then analyzed for TOC, pH, conductivity, anions, base cations, alkalinity, acidity, sulfate, Al, Cd, Fe, Mn, Cu, Zn and Pb.

Nationella prov i NO : Verktyg för likvärdig bedömning eller dolda svenskaprov som diskriminerar?

This study is focusing on students at compulsory level and their performance in national exam tests when the students first language is taken into account. Students in Swedish schools with non-Swedish speaking parents commonly follow language classes for limited Swedish proficient students. How does this affect their results when tested in other subjects as physics,biology and Chemistry? A general claim is that national tests can provide data for balancedand fair grades. This view is challenged in this paper, through Principal Component Analysisof test results that shows a difference between schools when the schools social position and share of limited Swedish proficient students are measured.

Lillån : Statusbedömning enligt EU:s ramdirektiv för vatten

In Sweden, the County Administration board is responsible for improving the water quality in lakes and watercourses according to the European Union Water Framework Directive. In Västmanland county, where river Lillån is situated, the County Administration of Västmanland have the main responsibility for the aquatic environment in that area. The knowledge about the different watercourses in the chatchment of river Lillån is today limited. The aim with this study was to evaluate the ecological quality of River Lillån based on water Chemistry analyses and benthic fauna investigations. The aim was also for the benthic fauna to compere different samplingsites and sampling methods with each other in order to see how the species composition changes in the river, and to see the advantages and disadvantages with different sampling tecniques.

Några aspekter på kemilärares tysta kunskap

Undersökningar visar att lärare, till skillnad från många andra professionella yrkesgrupper, sällan refererar till teorier när de anger vilka motiv deras praktiska verksamhet har. Den kollegiala diskussionen bland lärare är sällan av teoretisk karaktär utan handlar ofta om praktiska förhållanden . En stor del av lärarkunskapen verkar vara ?tyst?.? Tyst kunskap ska här förstås som erfarenhetsbaserad kunskap som uppnås genom praktiserande verksamhet, en typ av förtrogenhetskunskap som kräver överblick över situationen man befinner sig i. I det här arbetet studerar jag relationen mellan lärarens reflektioner om sin egen praktik i relation till lärarens syn på elevernas progression under kemilaborationer.

Kvantfysikens grunder i Gy2011 : En tolkning av kursplaner för fysik 1 och 2

AbstractThe beginning of the 20th century gave birth to quantum physics. Within years it revolutionized material science and converted the theoretical foundations of modern Chemistry, and to some extent even biology, to physics? new branch, molecular physics. Merger of relativistic and quantum physics soon led to the development of quantum field theory and a deeper understanding of the elementary constituents of matter. Part of this development found its way into high school textbooks as early as in the 1950s.

Hur kan intresse utvecklas för fysik och kemi i grundskolans tidigare år : - En analys av tidigare forskning

I den senaste PISA undersökningen från 2012 testades elevernas kunskaper i matematik, läsning och naturvetenskap hos femtonåringar runt om i landet. Sverige var det land som försämrat sina resultat mest av alla deltagande länder inom samtliga områden. Detta tyder på att något måste göras. Vi har studerat hur man kan väcka intresse för ämnena fysik och kemi inom naturvetenskapen. Detta för att öka de naturvetenskapliga kunskaperna hos eleverna i skolan.

Tillverkning av mikronålar för medicinsk tillämpning

Transdermal drug delivery, besides painfulinjections with syringes, has long been associatedwith small size particle pharmaceuticals, which candiffuse through the skin. This method of drugadministration has only been applicable on a smallnumber of drugs, where active molecules are smalland delivery time should or can be long.Other drug delivery options are oral administrationand injection with hypodermic needles (ordinaryhospital syringes). In oral administration thestomach and liver tend to dissolve the drug and theeffect becomes more difficult to anticipate, anddrug delivery rates difficult to control. Hypodermicneedles are used as a mean of drug injectiondirectly into the bloodstream. This method ispainful and risks infection due to tissue damageand skin penetration.One way to get a painless non-damaging techniquewith high delivery rate that still can delivery largemolecules is to manufacture an array of microscopichollow needles and equip them with a pumping unitthat delivers the correct amount of drugs.This thesis shows the technique and possibility ofmanufacture micromachined needles using low costtechniques of Ion Track Technology (radiation ofheavy ions creates porous materials), electrolessdeposition (non-current activated wet Chemistrymethod of depositing metal) and electroplating.

Vad efterfrågas av den : En jämförande studie mellan Socialförvaltningen, Försäkringskassan och Arbetsförmedlingen

ABSTRACTThe purpose of this c-level essay shall try to illustrate how a good leader is formed. We have investigated what influences leadership style, personal characteristics or individual competence have when recruiting a new manager. This study has been carried out with comparative applications because we wanted to study the similarities and differences between the Unemployment Office, the Social Insurance Office and the Social Welfare Administration.We have used a qualitative method in interviews both with employers as well as the from the trade union representative?s perspective. Part of our results indicates that the trade union representatives and the employers are not always unanimous and do not request equivalent characteristics and knowledge at recruitment.
