Off-Shore Blackboxing & Global Software Development : En studie av utmaningar och möjligheter med distribuerad systemförvaltning
Global Software Development (GSD) is based on a geographical distance where teams are spread throughout the world. The related research have for a long time addressed the challenges presented by geographical distances. GSD is basically a necessity for many businesses to use in order to reduce development costs, reduce production time and to maintain high quality. The study aims to investigate the relationship between the reality of a specific maintenance project. Thus, our research question: How do distributed maintenance teams experience temporal, geographical and socio-cultural distances? To achieve the purpose of the study, we chose to perform a case study of a global consulting company which recently started a new system maintenance project.
Följsamhet till riktlinjer för handhygien hos hälso och sjukvårdspersonal : en litteraturstudie
Introduction: Good hand hygiene practice is the single most important measure to reduce the spread of bacteria and viruses in healthcare. For nurses, this has become more important as the spread of multidrug-resistant bacteria in hospitals is increasingObjective: To identify factors that are important for adherence to hand hygiene among health care workers with patient contact.Method: Systematic literature review. Original articles were searched in PubMed and Cinahl.Results: Factors of importance for compliance was profession, lack of time, knowledge/education, physical work environment, attitudes toward hand hygiene, and dry hands.Conclusion: More education, less workload and more visible placement of hand disinfectant containers are examples of actions that could lead to the improvement of staff hand hygiene and reduce the incidence of healthcare associated infections. Due to the fact that health care workers around the world have different training and approaches, the result of this study may be difficult to use. To increase adherence to hand hygiene, a similar study limited to a specific country, such as Sweden, would therefore be interesting to carry through.Keywords: hand hygiene, Infection Control, Compliance..
Antibiotikaresistensgener: förekomst och spridning i akvatisk miljö
Antibiotikaresistens hos bakterier har de senaste årtionden ökat drastiskt och är idag en av de största medicinska utmaningarna samhället står inför. Resistensutvecklingen har ökat i takt med den oförsiktiga användning av antibiotika som präglat både sjukvård och djuruppfödning
i många år. Via akvatisk miljö har antibiotikaresistensgener stora möjligheter att spridas och
är svårkontrollerbara. Den här litteratursammanställningen undersöker vilka ursprung antibiotikaresistensgener i akvatisk miljö kan ha och om det kan ske en horisontell
genöverföring mellan bakterier. Vidare undersöks olika risker med antibiotikaresistensgener i akvatisk miljö, vilken möjlig roll de kan ha i resistensutvecklingen och hur de kan spridas tillbaka till människor och landlevande djur.
Antibiotikaresistensgener i akvatisk miljö kommer ifrån utsläpp av resistenta bakterier från djuruppfödningar, akvakultur, sjukhus och bostäder.

Det medeltida Visby : en kritisk studie av disskusionen om stadens etablering
Visby is a city that at first glance is of medieval origins. The popular image of scientists today is that the city was formed in the Middle Ages. According to some of the researchers Visby was formed during the Viking Age, it is based on the basis that the area has been used for a long period. Urban development in the Nordic countries is complex and there are different opinions as to why the Nordic cities emerge. It is important to shed light on the underlying process on why cities are emerging to provide clarity as to why Visby city is emerging.
Energikartläggning av Försäkringskassans lokaler : rekommendationer för ett fortsatt energieffektiviseringsarbete
With new energy directives in place, the Swedish Social Service (SSS) stands beforethe challenge how to reduce the energy demand in its locales. It is a complex matter,as the locales are rented from various property owners and it becomes a question ofhow to reduce the operational electricity and influence the property owners to workmore with energy efficiency. This thesis takes a balanced research approach in threeparts. Firstly a qualitative part in form of interviews with personnel at the SSS and itsproperty owners, secondly a quantitative part of descriptive nature in form of energystatistics and thirdly a literature review of Energy Management (EM) Supply ChainManagement(SCM), Green Supply Chain Management(GSCM) and EnviromentalPerformance Indicators (EPI). This in order to be able to give normativerecommendations of how the SSS should act to reduce its energy consumption in itslocales and provide new insights on how EM, SCM, GSCM and EPI can be applied ineffect.
Värmeöverföring i bergvärmesystem : En numerisk analys av den ringformade koaxiala borrhålsvärmeväxlaren
The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.
Vanans makt : En kritisk granskning av Pierre Bourdieus bidrag till aktör-strukturdebatten genom George Herbert Meads tänkande
The purpose of this essay is to critically review Pierre Bourdieus contribution to agency ? structure debate. I will do this with help from the thinking of George Herbert Mead. My aim is to show that Mead can provide valuable knowledge to Bourdieus theory.Pierre Bourdieus notion of habitus is his solution to the dilemma between agency and structure. It is in the habitus that the objective structures meet the inner, subjective structures and this results in various actions.
MATSVINN FÖRSVINN - En kvantitativ studie om hur ett CSR-argument kan involvera konsumenten i kampen mot matsvinn i butik
Every year 67000 tons of food is wasted by Swedish retail stores. The waste implies financial losses for the retailer and it has a huge impact on the global environment. Reducing in-store food waste is thus a win-win situation for both retailers and society. The most effective way to reduce waste is primarily by optimizing the logistics of supply, but customers expect a store with a wide range of products and stuffed shelves. Thus there will always be products about to expire.
Viskleken : Ett gestaltande arbete från text till upplevelse
In my project, Cups on the run, I have studied the relationship between ceramic utility objects and different environments, when moving them off the table. My background as a potter has been the starting point. From there, I wanted to see if I could expand my craft to the space beyond. With the cup, which for most people has a clear function and a relation to us human, in repetitive structure I explored the spatiality and architecture in various environments. Life fascinates me through how everything is made up of tiny parts that together create the tangible and intangible.
Förstudie till våtmark i Rimbo : Design för optimal hydrologi och kväverening
The euthropthication of the Baltic Sea is a threat that is beginning to be taken seriously by the governments concerned. In Sweden, regulations concerning the allowed nitrogen (N) concentration in the effluent water from wastewater treatment plants are being tightened up. The Rimbo wastewater treatment plant has been imposed to reduce the annual mean concentration of total N in the effluent water to levels below 15 mg l-1. A more and more common way to reduce the nitrogen level in wastewater is to let the water pass through a wetland. This study investigates the possibility to build this kind of wetland at the outlet of the Rimbo wastewater treatment plant.A prestudy of the topography, soil characteristics and groundwater flow indicates that the land area in question is well suited for the construction of a wetland.

Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.
How Venture Capitalists can use their Network in order to reduce the Information Asymmetries between themselves and the Venture Management Team
The purpose of this study is to increase the understanding of how venture capitalists can use their network in order to reduce information asymmetries between themselves and the venture management team. A qualitative approach with semi-structured interviews, consisting of open questions, have been used to receive gradate information in order to reach our explorative purpose. Our theoretical framework consists of relevant studies made on the dynamics of networks and the problems that can arise in the complex relationship between a principal and an agent. We have been interviewing two venture capital firms and therepresentatives from two business angel networks. We also made an additional interview with an influential financial actor in order to try to verify our conclusions Our conclusions are that an extensive network can be used by venture capitalists in order to; verify ventures? technologies, complement the competences in the venture management team, and arrange co-investments, resulting in reduced information asymmetries between themselves and the venture management team.
