The lack of fresh and clean water today causes severe problems, mostly in developing countries. Waterborne diseases like typhoid, cholera, amoebic dysentery and diarrhea create health problems and deaths among people. There is a need for low cost interventions like household-based water treatment and safe storage (HWTS). Solvatten AB is a Swedish company based in Stockholm. Their product, Solvatten, is a household water treatment unit that can treat water containing viruses, parasites and bacteria.

Syftet med uppsatsen är att ta reda på vilka faktorer som ligger till grund för bankers riskklassificering av fonder. För att få svar på frågan sökte vi kontakt med de fyra storbankerna, varav tre kunde ställa upp på intervju (Handelsbanken, Nordea och Swedbank). Dessa banker intervjuades via telefon då detta var den bästa metoden enligt vår synvinkel. För att få mer klarhet i ämnet har svaren från intervjupersonerna kompletterats med publicerat material på respektive banks hemsida.Det som framkom efter insamlingen av allt material från bankerna var att samtliga banker använder sig av skalor för att presentera risk på fonder. Skalformatet samt färgsättning varierar dock mellan bankerna.

SammanfattningDen finansiella marknaden har under de senaste decennierna till stor del präglats av både stark ekonomisk tillväxt och stora kriser, detta har lett till att risken relaterad till sparande och investeringar har blivit allt viktigare att kontrollera och undersöka. Samtidigt visar statistik från SCB att de svenska hushållen investerar allt mindre i aktier vilket kan skapa problem, både för den finansiella branschen i sig och det framtida välståndet. Dagens pensionssystem riskerar att inte klara framtidens ökande utbetalningsnivåer som krävs för att underhålla en allt större, äldre befolkning, som även lever allt längre. Detta är ett problem som gäller för hela EU och därför blir det allt viktigare med ett privat sparande, och därigenom att investera rätt.För att hjälpa privatpersoner att investera rätt, genom att utnyttja sin nivå av risktolerans, samtidigt som man gör det lättare för kreditgivare och rådgivare att kunna erbjuda korrekta produkter och investeringsstrategier, syftar denna studie huvudsakligen till att undersöka om det finns samband mellan olika demografiska och socioekonomiska variabler och nivåer av risktolerans. Med hjälp av tidigare studier valdes följande variabler att undersökas: kön, ålder, utbildningsnivå, relationsstatus, sysselsättning och inkomstnivå.

Ground work like blasting, piling and excavation has always had a great influence during the planning phase of a construction project since it can cause damages on adjacent buildings and have severe economic consequences. This thesis deals with how vibrations caused by ground work influence near-by buildings and what methods geotechnicians and construction entrepreneurs use to handle these risks.The purpose of this thesis is to explain risk management in relation to ground work. In order to achieve this I have used a qualitative method by interviewing a geotechnician and a ground work contractor who possess knowledge and experience useful to this thesis. The result shows that vibrations from ground work spread through the ground as seismic waves that cause displacements and packing in the ground visible in adjacent buildings as cracks and subsidence damages. Geotechnicians study ground work vibrations by means of ground investigations and experience from previous projects in order to produce a risk analysis that entrepreneurs can use to reduce damages.

Syftet med studien var att undersöka hur människor upplever och hanterar risken att bli utsatt för hot och våld från klienter i arbetet. En kvalitativ ansats valdes vilket innebär att fokus har lagts på subjektiva upplevelser och erfarenheter av studieområdet. Studien genomfördes gentemot Socialtjänsten från två kommuner och urvalet bestod av intervjuer med elva socialsekreterare vars arbete innehåller myndighetsutövning och kontakt med klienter. Analys av data gjordes enligt induktiv tematisk analys. Resultaten visade att det föreligger en risk att bli utsatt för hot och våld av klienter men den upplevs vara liten.

This paper will discuss the proposed reintroducing of a final degree in upper secondary school. In a public government inquiry that was released in March 2008 a proposal about reintroducing a final degree in upper secondary school was presented. A final degree has not been a part of the upper secondary school science 1968. Why was the system with a final degree abounded and why do the government want to reintroduce it?Research in pedagogy has through the years presented numbers of theories about assessment.

ITT Flygt is a world leading company that mainly manufactures submersible pumps. A problem of ITT Flygt is that product development projects rarely manage to hold the estimated project time. It shows that something unexpected occurs in projects quite often, which results in delays. The delays can both be due to an optimistic time plan of projects and risks in product development projects which are not discovered at an early stage. This added with unforeseen delays makes it difficult for ITT Flygt to estimate the duration of their projects.The goal with the Master thesis is to examine a suitable method for simulation of project time.

ABSTRACTObjectiveThe aim of this study was to determine if and what kind of scientific evidence there is for the advice that breast-feeding can reduce the risk of sudden infant death syndrome (SIDS). The aim was to investigate research on the subject published in the last 15 years.MethodA systematic review without meta-analysis with relevant original articles published in the last 15 years.Main resultsAfter searching for articles 26 relevant articles were used for this study and two were excluded because of poor quality. Mixed results were shown on breast feeding and the risk of SIDS. Breast-feeding seems to have some protective effect but can?t be separated from known risk factors of SIDS.Plain language summaryBreast feeding can be regarded as a preventive measure against SIDS.

Syftet med uppsatsen är att undersöka hur svenska pensionsfonder presterat under perioden 2005-01-01 till 2009-12-07. Detta vill vi undersöka då det sker stora förflyttningar av pensionskapital i stundande tid inom det svenska pensionssystemet. Undersökningen innehåller ett urval på 25 svenska pensionsfonder hos sju av de stora svenska pensionsförvaltarna. Fyra fondtyper har använts i undersökningen: En aktiefond, en blandfond och två olika räntefonder. Utifrån historisk data har vi tagit fram avkastning och risk för aktuell tidsperiod hos fonderna.

The aim of the study was to test whether or not menstruating women?s levels of haemoglobin changed after three weeks consumption of Blutsaft. Previous studies on nutrition supplements including iron have shown increased haemoglobin levels. On Blutsaft, however, there are no studies carried out and published. The participants in this pilot study were menstruating women, with haemoglobin levels between 105 and 125 g/l at the initial part of the study.

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

The aim of this thesis is to examine the archivist's professional role in public authorities and discuss if, and in what way, the profession is effected by the new swedish process oriented archival description system. The study focuses on swedish authorities and does not make any international comparisons with other institutions. Neither does it investigate archivists workingin the private sector, but centers on public institutions.The survey is performed in five swedish public authorities, using interviews and observations. Grounded theory is used as a method initially in the purpose of keeping an open mark towards the object of study. The initial results led on to questions about how well the archivists perceived that communication within the authorities served, and how this in turn prepossessed their work situation and the professional roles in which they found themselves.

An efficient market implies that the use of fundamental analysis should not result in excess return, and that any return exceeding the market average can be explained by compensation for risk, accord-ing to The Capital Asset Pricing Model (CAPM). The focus of this study is to test whether the suc-cessful investment strategy developed by Piotroski (2000) generates excess return on American data, after risk adjustment by using Fama & French?s (1993) 3-factor and Carhart?s (1997) 4-factor CAPM. Initially we form stock portfolios based on companies characterized by high book-to-market values, additionally, we divide them into different performance classes by ranking them with Piotroski?s (2000) measure of financial performance, F_SCORE.

Människans näringar och kulturer har orsakat landskapsförändringar som på många håll i världen lett till flera ekologiska konsekvenser som erosion liksom övergödning av vattendrag och hav. Skogsbruk såväl som jordbruk har därutöver resulterat i stora utarmningar av den biologiska mångfalden på jorden. Sedan en tid har jordbrukets negativa konsekvenser fått alltmer uppmärksamhet inom bland annat politik, forskning och näringsliv, varav somliga människor aktivt försökt stoppa det negativa händelseförloppet som manifesterat många av världens odlingslandskap. Diskussioner som innefattar ekosystemet och dess så kallade tjänster för människans såväl som andra organismers överlevnad och välbefinnande erhåller därutöver mer och mer fokus i strävan mot miljövänligare alternativ för storskalig odling. I sökandet efter mer ekologiskt sunda odlingssystem har intresset igen väckts för agroforestrysystem, som kombinerar vedartade växter med vanligt förekommande grödor. Etableringen av lähäckar på respektive intill odlingarealer i Skåne kan bidra med flertalet ekosysystemtjänster vilka bevisats stoppa ex.
