Jämförelsestudier av Takkonstruktioner med Stora Spännvidder
The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.
Konstruktion av maskin för Tillverkning av sågblad
The saw blade producer, Håkansson Sågblad AB, patented in the U.S. a new blade profiledesigned specially to cut fish and meat. The most important advantage of that blade is that its teethare not set, therefore the material lost when cutting is really smaller. The special geometry of thatprofile made that nobody had found a proper way to produce it before.The goal of the outlined work is to develop a machine to produce these new blades in afeasible way.The research approach of the project can roughly be divided into three phases:1.- Invention and development of a proper distribution of blades to produce a big amount ofthem at the same time.2.- Research of the best production process to produce the blades.3.- Main design of the machine to produce the blades.In the Thesis these three points are carefully developed and studied in the form of the startpoint of a really bigger project. Some tests had been done in order to prove all the analytical ideasand the results obtained had been satisfactory enough to give Håkansson the start point of a bigbusiness.
Erfarenhetsåterföring :
This thesis has been done in collaboration with Peab Stockholm Building 3, which is a region within the Peab Sverige AB. The report is based on a survey and studies of Peab business management systems and production literature. For general information gathering has literature from well-known sources collected in libraries and through the Internet. It shows through the work that Peab has routines for experience feedback in the construction process, but that these procedures work in a small scale and the practical work experience feedback does not work at all. This is also something the construction industry in general also perceived as problematic. The questions in the report are of a wide scale and concerns construction errors cost, how the employees perceive that the company takes advantage of the skills and the mental stress in production line. The goal is to find how Peab Stockholm Building 3 will work on the experience feedback to allow for better productivity. In conclusion, the report author tries to demonstrate what can lead to increased productivity and improved work experience..
Risk för spridning av ogräsfrö med rötrester : en litteraturstudie
With an increasing production of biogas follows an increased amount of digestate. This could potentially be a valuable source of fertiliser with the destruction of weed seeds as a possible advantage. However, there have been some concerns regarding the product still containing viable seeds of weed.
In this Bsc thesis the results of previous research on the fate of weed seeds in biogas production is summarized. It is also a comparison of research on the effect of similar processes such as silage, compost or animal passage on seeds. The purpose of this is to evaluate risks of spreading viable seeds, potentially problematic species and perhaps to find out how to eliminate the risks.
The literature review revealed that previous research mainly indicates low risks regarding many of the tested weed species, but not all studies show the same result, therefore extended research on the subject is desirable.
?Nej, men jag söker väl tills jag hittar?: En studie av discoveryverktyget Summon utifrån ett användarperspektiv.
The purpose of this bachelor?s thesis is to examine how students at Högskolan i Borås experience the web-scale discovery service Summon, based on the theoretical model of ?The Five Dimensions of Usability?, defined by Whitney Quesenbery. The study aims to answer the following research questions: How do the students execute search assignments in the Summon interface? How intuitive and easy to navigate is the system from a user perspective? What are the students? opinions about Summon, regarding usability?Five students with varying information seeking skills are asked to perform search assignments during controlled observation, followed by semi-structured interviews. Our findings are presented in the context of previous research and show correspondence with the results of related studies.
Indexeringskonsistens: En litteraturgenomgång och en undersökning i LIBRIS
The aim of this thesis is to investigate indexing consistency in LIBRIS, a Swedish national union catalogue, where searches can be carried out among almost five million titles. To calculate consistency, indexing terms of translations and indexing terms of documents in their original language have been compared. I have used a total of 100 such pairs in the study. There is a lot of different methods that can be used when consistency is calculated, in this study Hoopers and Rollings methods have been used since they are two of the most commonly methods used and also have the advantage of being fairly simple to use and understand. In the thesis, differences in consistency between indexing terms consisting of names and general indexing terms and differences in consistency between controlled indexing terms and uncontrolled indexing terms are also compared.
Hund som komparativ modell för autoimmuna sjukdomar :
In this essay dog as a compatible model were put against human. The major histocompatibility complex (MHC) genes were compared between dogs, human, cat and mouse. To evaluate dog as a model and study similarities and differences was the aim with this review.
Dog as a model contributes to understand mechanisms behind autoimmune diseases and showed clearly histological similarities between human and dogs concerning the skin disease mucous membrane pemphigoid (MMP)/cicatricial pemphgioid (CP). Further genetic evidence motivated the choice of using dog as a comprehensive model when the MHC-complex correlated with hypothyroiditis in Doberman dog as it does in human. Physiological similarities with low levels of thyroid hormones (T3 and T4) together with high level of thyroid releasing hormone (TSH) were found in the same way as in human.
Kvinnliga avdelningschefers erfrenheter av sitt ledarskap inom vården

The aim of this study was to describe female head nurses? experience of their leadership in healthcare. The collection of data has been carried out from interviews.
Maktspel i gaturummet : Cyklisternas säkerhet i Stockholms innerstad
The purpose of this study was to investigate whether social counselling via chat conversations could meet the criteria for a professional conversation, and how the six social workers who were interviewed felt that it had affected the profession and the clients who are seeking their help.Communication, professionality, power, roles and regions are the key topics of this study. A hermeneutic approach has not only influenced the interviews but also the content analysis that was used to encode the results.The interviews revealed that the chat conversations was a successful tool but not entirely without difficulties. The initial contact making between the client and the social worker favours the client, since she/he remains anonymous and that was the main advantage of the method. The biggest concern however was that in the anonymity it is not possible to report cases that the social worker are obligated to. The changing of forum does not necessarily affect the professionality but due to the faceless chat conversation an entire dimension of communication disappears because the loss of body language.
Innovate or Evaporate : -En kvalitativ studie av idéhantering på IKEA AB
The thesis focus on how organizations can improve the ability of absorbing coworkers ideas in purpose of gaining long term competitive advantage through innovations. The study was conducted at IKEA AB where a campaign to collect coworkers ideas was a big success given the quantity of ideas collected. This fact allows a comparative analysis of idea management in the shape of campaigns and in comparison, idea management in the everyday line-organization.The analysis show that fundamental factors for innovative environments such as organizational climate, culture and leadership perceives auspiciously by the respondents. However, lack of infrastructure such as systems and processes hinders coworkers ambitions to contribute with ideas.An important issue in idea management is the treatment of incentives for innovation. Results of the study show that the ?soft? incentives ?feedback, encouragement and attention have a higher impact in coworkers willingness to the contribution of ideas than for instance monetary rewards..

Farmers? main reason for crossbreeding dairy cows is that they have seen a decline in functional traits, especially in the Holstein breed. Throughout crossbreeding, the farmers can combine functional and production traits of different dairy breeds and utilize the heterosis effects which emerge when two or more breeds are crossed. Results from different studies with Holstein crossed with Jersey, Brown Swiss, Normande and Scandinavian Red have shown that the crosses had higher fertility, longer productive life, had fewer stillborn calves and had easier calvings than purebred Holstein. The Holstein crosses have shown very good results and sometimes even better than the purebred Holstein for fat production, which gave higher amount of energy corrected milk (ECM) and higher income for the farmers.
Konstruktion och utvärdering av diplexer
The report descripbs how a diplexer for a hybrid analog/digital filterbank has been constructed and tested. A diplexer divides the frequency band into two different bands that do not who doesn't overlapp each other. The sampling rate for the two ADC:s is 80 Msps, and therefore it is advantage to have zero at 80 MHz. The reason for this is that a proposed class of hybrid filterbanks with very good quality requires a zero at or close the sampling frequency to work well. The diplexer was made in three versions.
Uppmärksamma behov genom att uppmärksamma alla : en studie om förebyggande arbete på familjecentraler
Purpose: To examine how a tour operator works to implement sustainability in the development of the business, as well as what significance it has to consumers in selecting a tour operator. Furthermore, the purpose is to provide recommendations on how tour operators should work to communicate their commitments.Methodology: The research strategy applied is a case study which follows an abductive approach. Qualitative and quantitative methods were applied to complement each other. A semi-structured interview with a tour operator and a consumer survey constitute the empirical foundation.Conclusion: The conclusion of the study is that consumers show a positive attitude towards CSR, but do not see it as a determinant when choosing a tour operator. Thus, CSR does not constitute a competitive advantage against competitors.
Digital Materia
Med tankar från pedagogen Montessori och filosoferna Platon och Baudrillard har detta arbete behandlat frågor om datorn och dess betydelse för en grafiker. Frågeställningen formulerades efter hand och lydde tillslut: ?Hur kan materia te sig i digital form?? Forskningen resulterade i en hypotes för hur digital materia skulle födas i datorn: genom att blanda två uppsättningar av data, såsom två genuppsättningar tillsammans skapar en ny organism. Under produktionen utvecklades därmed en metod för hur en grafiker ska kunna skapa tillsammans med en dator. Syftet är att ge andra grafiker ett nytt sätt att se på digital grafik.
Ekonomin i syrning av spannmål till mjölkkor :
In this dissertation I have tried to figure out if it possible to make any money on acid grain to feed cows through a case study. The method is a case study combined with a documentary research. At present the farm sell all grain in connection with harvest and buy it back continuously in the neighbourhood, I have compared that with an alternative where I invest in a construction for to store acid grain on the current farm.
I have delimit me to only have a look on acid grain because I think that is one of the cheapest way too store grain in smaller aplenty. Before beginning with acid grain is it important to be versed in how everything works and the risk to keep on with acid grain.
One disadvantage is that the acid grain is not possible to store more than 12 months with out acid it once again. It is also easy to get mould in the pasture if it is not acid enough.
