Google Scholar eller Scirus för vetenskapligt material på webben? En utvärdering och jämförelse av återvinningseffektivitet.
This thesis evaluates and compares the retrieval effectiveness of the two search engines Google Scholar and Scirus, which both specialises in indexing scholarly material on the web as well as journal articles. Thirty search queries are used and the first twenty retrieved documents for each query are examined for topical relevance and scholarly content. The search queries are based on legitimate information needs taken from a scientific questionbox on the web. Queries are expressed with advanced search operators and are the same for both search engines. Precise relevance criteria are set up and a binary scale is used when judging.
Brandskyddsindex Visby innerstad
The aim for the project was to develop a risk analyse tool for measuring the fire safety level in Cultural Heritage buildings of Visby, Gotland. In 1995 Visby were taken into the Unesco:s World Heritage List with the explanation ?Visby is an outstanding example of a Northern European walled Hanseatic town which has in a unique way preserved its townscape and its extremely valuable buildings? One of the demands for the tool was that it should be easy to use and result into a Ranking level in examined buildings. The user of the tool is recommended to be personnel in the fire department. To develop the tool a Multi Attribute Decision Making (MADM) method was used.
Optimering av driftläggningar i Fortums nät
Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a Ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

Kan ät- och liggbås påverka kornas välbefinnande?
The purpose of this literature review was from dairy cows? behaviour and welfare point ofview describe how feed bunk and cubicles in a loose house system should be designed. Todaydairy cows in Sweden and in the world have high demands because of a high milk production,stress and higher risk of being afflicted with diseases. Through selection in breeding the bestquality can be performed, but high demands of the environment for the dairy cow is above allalso important for a good welfare and for a good milk production. Feed bunks and cubiclesare just some parts to be designed in the best way for a good animal welfare.
"Öppna jämförelser"- morot eller piska? : En fallstudie av hur förändrad styrning av sjukvården påverkar läkare i deras yrkesutövning
The governance and control of healthcare organizations has traditionally been run byprofessions inside the organization (Fölster et al., 2003). During the last decades Swedishhealthcare has undergone an institutional transformation where the governance has changedfrom professional governance to a more market like one (Sahlin-Andersson, 2006). Governingof healthcare can however be problematic as professional work is characterized by a highlevel of autonomy and tacit knowledge (cf. Tsoukas, 1997, Freidson, 2001). An expression ofthe new kind of governance is the annually published report ?Öppna jämförelser av hälso- ochsjukvårdens kvalitet och effektivitet?.
Prissättningen av bostadsrätter: Vilka faktorer påverkar priserna, vad är riktpriset för en lägenhet?: - En mikrostudie av Södermalm i Stockholm
Those who have invested in apartments, i.e. tenant-ownership, within the city centre of Stockholm have gained a higher than expected return on investment due to a buoyant real estate market. During the latest twelve-month period, the prices have risen more than 20 per cent in the city of Stockholm, resulting in an increased wealth together with a higher debt burden among investors. The aim of this thesis is to investigate which factors determine the prices from a micro perspective, and to what extent. An attempt is particularly made to estimate the degree of capitalization of the monthly fees; a factor which has turned out to be important according to other studies; but also to construct pricing models in order to set target prices for apartments.
Inhysningssystem för växande ungtjurar
The purpose of this study was, if possible, to find a housing system for growing bulls that was as optimal as possible for the animal welfare. In order to select housing systems you must take into account the size of the group, body weight and the type of floor. Seven of the international most common housing systems were compared, straw bedding, deep straw bedding, sliding straw bedding, concrete slatted floor, rubber coated slatted floor, cubicles and feeding cubicles. Studies that have examined the proportion of tail, claw and leg injuries and the presence of unnatural behavior in the different systems. In summary, all studies showed that soft underlay were beneficial for the animals in terms of the proportion of bone lesions and swellings.
Marknadsinträde i Kina? : de svåraste inträdesbarriärerna för svenska företag vid marknadsinträde i Kina
China is considered as one of the world?s fastest growing economies and the future of China looks promising. Even though the Chinese market attracts many new foreign companies to enter the market there are entry barriers which companies may encounter as obstacles, which will aggravate the market entry in China. As a result companies loose business opportunities and therefore it is of great importance for Swedish companies, which are planning a Chinese market entry, to identify which entry barriers that are considered to be the most difficult obstacles to overcome.The purpose of the thesis is to examine which entry barriers that are generally considered to be the most difficult obstacles for Swedish companies to overcome when entering Chinese markets and to rank the five most difficult entry barriers to overcome.Information about these entry barriers have been gathered from Swedish companies, which have carried out successful market entries in the Chinese markets, through an e-mail questionnaire.The result generally shows that the most difficult entry barriers to overcome in China were: bureaucracy, property laws, language, cultural differences and difficulties finding local partners. The Ranking of the entry barriers? result shows that bureaucracy is the most difficult obstacle to overcome, followed by cultural differences, language, relations and access to distribution channels.We conclude that companies experience different difficulties overcoming these entry barriers, which depends on the companies? size, years in China, markets and if the entry barriers were considered controllable or uncontrollable.
Som en schackpjäs : om socialsekreterares upplevelser av sin yrkesstatus vid handläggning av försörjningsstöd
The purpose of this essay has been to answer the question of whether or not administrators of economic support perceive that their professional status is ranked lower than that of their coworkers in other fields of the social services. We set out to study whether or not their comparative status differed depending on their use of standardized assessment instruments and if their experience with regards to professional status differed depending on the size of the municipality they worked in. We also wanted to determine in what way (if any) the comparative status manifests itself and what factors influences it.We?ve utilized method triangulation in order to answer the questions posed in our purpose. The quantitative study was conducted using a questionnaire and the qualitative with three interviews.
Kliniskt datainsamlingssystem med beslutsstöd - Användarutredning och gränssnitt för Sahlgrenskas akutintag
Extra high requirements are made on all systems in health care that they are functional and usable,´something, however, that is not always the case. At Emergency Admissions at Sahlgrenska University´Hospital many systems are in use at the same time and it happens that much overhead is caused by having to fill in the same information in different places. In addition, data that is gathered is to a large extent saved in free text format, which means that it cannot be used in a larger context such as research, quality control or for decision support. Data is saved in the patient file only for the treatment process of the individual patient.A data collecting system with decision support functionality could be a first step towards reducing Emergency Admissions? costs and patients? waiting times by providing a structured method of data collection.
Mozzarella : En djupdykning i ostmassan
Worldwide consumption of cheese has increased over the years. The average Swede consumes somewhere around 20 kilograms of cheese per year, which is an increase of a 100 % over the past 50 years. One of the most popular kinds of cheese during the past decades is mozzarella, due to its? use as pizza cheese. Flavor and consistency differ between the traditional kind, made out of buffalo?s milk, and the industrially made kind, made out of cow?s milk.
Hur står det till med jämställdheten? : En kvalitativ studie om arbetet med jämställdhet på grundskolor i Kronobergs län
This study is an assignment from the council of Södra Småland county to investigate how equality between boys and girls progresses at compulsory schools in Kronoberg county. The study was undertaken to find suggestions on how work with equality could best be stimulated.The key question was to elaborate how a decentralized rule and structural context of an organisation can affect an implementation of political decisions. The methodological approach adopted can be defined as inductive, it was analysed how the respondents from some selected schools in Kronoberg county themselves relate to the concept of equality between men and women and their experience and understanding of how the concept of equality between sex is understood in their work at school.School-legislation today demands that active measures are undertaken to promote equality between boys and girls and in general almost all the respondents of my study describe equality as an utterly important question. My findings although, at the same time, indicate a gap between rhetoric and practice. The findings of my study suggest that structural relations and a decentralised organisation can constitute a hindrance for implementing equality between men and women in schools.
Application of Design for Safer Urban Roads and Junctions: Selected Countermeasures
Road design with focus to safety has been extensively developed in last decades in Nordic and some other EU countries with the main aim to achieve a decrease in a number of accidents and fatalities on the roads. These countries gained many valuable experiences, but they had to sacrifice great effort, expenses, and time to reach the present art-of-state. The purpose of the Master?s Thesis is to review some design approaches with focus to safety and discuss the general way that they may be applied. The Master?s Thesis studies safety in three levels: (i) general - design standards, national safety policies and road hierarchy; (ii) local authority and road administrator; and (iii) three specific safety countermeasures - junctions, pedestrian crossings and traffic calming.
Utvärdering av Språklig Snabbedömning för barn i åldrarna 2:6-3:6 och 4-6 år
Bakgrund: Språklig Snabbedömning (SB) är ett språkligt bedömningsmaterial framtaget för att på kort tid (< 1 h) kunna bedöma ett flertal språkliga förmågor. Användningen är utbredd i Västerbottens läns landsting men den praktiska användningen av bedömningsmaterialet har inte undersökts systematiskt.Frågeställning: Är resultaten av Språklig snabbedömning jämförbara med resultaten från bedömningar gjorda med normerade språkliga bedömningsmaterial?Metod: Data samlades in från arkiverade testmaterial för att kunna göra jämförelser mellan SB och kompletterande test. Totalt ingick 62 barn i undersökningen. Analysen genomfördes kvantitativt och kvalitativt genom att undersöka Rankingen i olika material samt detaljgranska skillnader och likheter i upptäckta språkliga fel.Resultat: Den kvalitativa utvärderingen av SB visar att materialet ger resultat som ligger i linje med normerade test.
