Optimering av skumdämpande additiver För användning i en lufttorkande vattenburen rostskyddsprimer
The development of defoaming additives is steadily progressing and there are therefore always new and improved additives on the market. Some modern additives provide the desired defoaming effects by themselves, in contrasts to previous additives that needed to be used in combination with other additives. The task of this bachelors thesis was to evaluate the possibility of using these improved defoaming additives, with the aim to find alternatives that give the system better defoaming attributes while, at the same time, using less of the primary products. The tests were carried out in the coating type Teknocryl Aqua Combi 2780. The coating is a waterborne air drying acrylat-latex/alkyd based coating that can be used for both single coat painting and primer.

Hjärtans god Choklad - Flavanols påverkan på blodtrycket
Kardiovaskulära sjukdomar och hypertoni blir allt mer vanligt i västvärlden. Trots livsstilsrekommendationer ökar antalet insjuknanden i hjärt-kärlsjukdomar, vilket har blivit en av de vanligaste dödsorsakerna i Sverige. Syftet med litteraturstudien var att undersöka om flavanol i kosten kan användas blodtryckssänkande samt att klargöra om flavanol påverkar den kardiovaskulära ohälsan. Metoden som användes var en litteraturstudie av redan publicerade vetenskapliga artiklar inom ämnet. Flertalet studier visar på att flavanol har en blodtryckssänkande likväl som andra positiva effekter.
Elektromagnetisk och mekanisk design av en 20MW turbogenerator
At the Division of Electricity at UppsalaUniversitythere are ongoing researches, including a research concerning turbo generators.Turbo generators produce a large share of electricity in the world; however they are costly mainly due to the fact that the cooling and ventilation that are needed to eliminate the excess heat from the generators are expensive. Turbo generators work with high efficiency and in this project, the main task is to simulate a generator while taking into account that the generator must be designed against self-oscillation, centrifugal force, exhaustion and heat. The turbo generator must be simulated without being too expensive and complicated.In this project, the dimensions of the turbo generator depend on the efficiency of it, and where the losses are in the generator. Furthermore, the optimum values need to be chosen with the help of the ACE simulation program. The report begins with an introduction describing the project followed by a task description that is dealing with the project.
"Än så länge går vi på känsla" : En studie av bibliotekariers hantering av kontroversiella medier
The purpose of this bachelor's thesis is to investigate how working librariansmanage controversial media. It builds on three debates in the media about libraries and booksthat have taken place during the years of 2012 and 2013. The questiones asked were: How dolibrarians manage racist media? How do librarians manage media that instructs on how tocommit crimes? How do librarians manage sexually explicit media? And lastly, how dolibrarians manage pressure from outside of the library? The theoretical framework consists ofRobert Hauptmans division of the two kinds of ethical strands of librarianship, in this thesiscalled ?Free information? and ?Information responsibly?. The method used to collectempirical material was qualitative interviews.
Lyftredskap för KL-trä - Hantering av horisontella och vertikala element i massivträ
A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Likabehandlingsprincipen i uthyrningslagen - om lön för arbetare inom bemanningsbranschen
In Sweden has the temporary agency work industry settled in an explosive way since the deregulation of the unemployment agency monopole in 1993. The demand of civil right for the employer that is rented out confronts the entire labour law regulation with new challenges.The purpose with this paper is an investigation of the principle of equal treatment in The Swedish temporary agency work act and also to create a deeper understanding of the effects of labour and employment relationship. An investigation of relevant collective agreements will be done to highlight the difficulties the principal of equal treatment is exposed to. Further on is there a will to gain understanding for the wage concept and what possible can be included in the wage concept in relation to the principal of equal treatment in The temporary agency work directive. By using the dogmatic method, an approach to descriptive identifying relevant sources of law and clarify the legal situation in the area.In the conclusions it will be determined that the principle of equal treatment in The Swedish temporary agency work act have different effects depending on if the temporary agency or if the client corporation is tied to an collective agreement alternative if a collective agreement is completely missing.
IMPLEMENTERING AV ARBETSMILJÖLAGENS ÄNDRINGAR, GÄLLANDE FRÅN 090101, PÅ BYGGARBETSPLATSER
In the EU there are EC Directives that Member States of EU should follow. Sweden has undertaken to transpose EC Directives regarding the working environment to Swedish Provisions. In 4 April 2006, the European Commission had some criticism against the Swedish implementation of the Construction Sites Directive. The Swedish Work Environment Authority has in response to this criticism reworked the Work Environment Act and related provision about building and civil engineering work. The changes came into force 1 January 2009.These changes have resulted in some working methods and even new responsibility subjects must be reviewed. The purpose of this exam project was to investigate if contractors and clients in the construction sector, had have time to update themselves on this front and adapt to these changes.
Lönekartläggning och handlingsplan : - en undersökning om det aktiva arbetet för jämställda löner

The purpose of this studyis therefore to contribute to a greater understanding of the regulation regarding postedworkers, their work environment and the consequences of it.
Or?ttvist flexibelt? En studie om hybridarbetets betydelse f?r r?ttvisa och v?lm?ende inom en organisation
The purpose of this study is to explore how hybrid work affects the experience of organizational justice and psychological well-being within an organization where working conditions differ between professional groups. Using a combination of semi-structured interviews and a quantitative survey, the study offers a nuanced understanding of how various work arrangements are perceived and interpreted by employees. The findings show that justice is not primarily about having equal conditions, but rather about how these conditions are understood and communicated within the organization. Many employees accept differences in work arrangements when they are perceived as logically justified and clearly communicated. However, when these differences lack explanation or are associated with injustices, frustration can arise even if employees understand the reasons behind them.
Självgående renslastare till sockerbetor :
Our greatest interest within crop farming is to grow sugarbeets, that?s why we want to
write about something new in this sector. We heard that a new concept had come to
Sweden so we wanted to find out everything about this machine.
This new technique was a self-propelled cleaning loader for sugarbeets. This machine is
supposed to replace a loader and a cleaning machine when the sugarbeets is going to be
loaded, cleaned and delivered to the sugerbeet factory. The cleaning loader picks up the
sugarbeets with rollers from the pile, which is placed close to the road.
"Fenomenalt" eller "De borde kunna mer om datorer" : En undersökning om datorhjälpen på högskolebibliotek
"Outstanding" or "They ought to know more about computers" : A study on computer support at university libraries.The main purpose of this study is to investigate the support computer users are given at university libraries. Further, the aim is to find out if the users thought they received the support that they needed. The study is carried out at two different university libraries. The data is obtained through interviews with the librarians, observations of the daily work at the information counters and questionnaires handled out to the users.The study indicates that variables such as knowledge, time and equipment play a central role in making the computer support successive. To a great extent the computer support is synonymous with information search, but it also deals with word processing and technical support connected with computer errors.
Komprimering av testdata för SOC : -En implementation av metoden vector repeat
Sammanfattning:De ökande testdatavolymerna som krävs för att testa moderna System-On-Chip (SOC) bidrar i hög grad till den ökande produktionskostnaden. De stora testdatavolymerna kräver stora och dyra Automatic Test Equipment-minnen (ATE-minnen). För att minska behovet av dessa minnen så har olika komprimeringsmetoder utvecklats.Denna rapport beskriver arbetet med att implementera en given komprimeringsmetod för testdata till SOC. Den metod som används heter vector repeat och den implementeras genom skapandet av ett för ändamålet avsett dataprogrogram. För att vector repeat ska fungera effektivt så förutsätts det att in- och utgångarna på den ATE som används kan delas in i olika portar.
Skarven : ? Produktutveckling av en oljedimavskiljare
This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.
