Vem vinner: fackboken eller den skönlitterära boken? : en studie över lånevanor i en 3:e klass i en mindre by i norra Sverige

The purpose of this thesis is to investigate the habits of borrowing books among third-grade pupils. My aim is also to study what significance their teacher and the librarian have on the pupils? borrowing habits. Based on the results from an experiment, two observations, interviews and by compiling a list of short summaries of literature relevant to my thesis. I wanted to compare earlier research with my own results and also reflect on remarks made by librarians and teachers concerning the children?s reading and use of the library.

Kända Varumärke - Större, Starkare, Säkrare

In todays high-technological society where the Internet plays a central role in our day-to-day life, many e-retailers are not able to attract customers to complete a transaction on their website. In order to succeed, many e-commerce sites must improve several safety aspects regarding online payment, in order to be perceived as a reliable and secured retailer. The purpose of this paper is to investigate if increment in various combinations and aspects in online payment will in fact improve the customer's perception of the e-retailer and result in completed transactions. In order to investigate this aspect, an experiment was conducted to be able to compare eight independent groups, that each had been exposed to a different security scenario on the online payment website of either a known or unknown retailer. Our results clearly prove that perceived security of the retailer's payment website increases willingness to purchase from the retailer.

Beräkningsprogram för gasfjädrar

This master thesis work was done by two students at Machine Design at KTH for Lesjöfors Stockholmsfjäder AB. The task was to develop a calculation program for gas springs. The program is going to ease the selection of gas springs for a given case of a lid that should be opened. The program is going to be used internal by sales people at Lesjöfors AB in Sweden and internationally. The program is therefore written in English.The program was developed in Microsoft Visual C# 2008 Express Edition.

Predation som selektiv kraft bakom differentiering av populationer av sötvattensgråsugga, Asellus aquaticus

Predation is a strong dective force on invertebrate prey. Asellus aquaticus differs in pigmentation reed and submerged vegetation habitats in lakes. Light pigmented individuals al vegetation dominated by Chara sp. while dark pigmented individuals dominate in the reeds. These differences have been hypothesized to result from background matching.

Från ax till möbel : förnyelsebara material som möbler

Förnyelsebara och/eller miljövänliga plaster som t.ex. biokompositer är ett eftersatt område inom möbelindustrin, där utvecklingen hittills ofta har inriktats på återvunna material. Jag har koncentrerat mitt projekt till detta område med inriktning på det förnyelsebara materialet veteglutenkomposit(VG) i samarbete med forskningsföretaget STFI-Packforsk och gjort ett flertal experiment i materialet. Det slutgiltiga resultatet har blivit en komposterbar stol i VG och ett flertal urnor samt materialprover. En av de stora fördelarna med materialet är att det är komposterbart och redan efter några veckor bryts ner vid kompostering, vilket bidrar till att dess miljöpåverkan blir så liten som möjligt.Vetegluten är en restprodukt från produktionen av etanol och kan när det blandas med glycerol och pressas under högt tryck och värme bilda materialet VG.

SiLu : Riktlinjer för spelmotor

Spelmotor är benämningen på den komponent som hanterar en del av mekaniken i ett datorspel. Förutom funktioner för grafik, fysik etc. finns också funktioner för rörelser, interaktion med världen etc. I detta examensarbete går vi in på hur en spelmotor för morgondagens mobiltelefon kan se ut, samt vad dagens mobiltelefoners hårdvara och mjukvara saknar för att dagens PC-spel ska kunna portas till dem. Stödet för att spela avancerade spel på mobiltelefoner växer ständigt och inom några år bör hårdvaran vara ungefär densamma som på PC.

Faderskapsanalys av tallfrö från Västerhus fröplantage : Skillnad i pollenkontaminering mellan öppen pollinering och pollinering inom ett avgränsat system

In this study, pollen contamination (measured by the number of seeds pollinated by pollen not belonging to any of the clones on the seed orchard) is compared between open pollination and isolated pollination environments in a Scots pine (Pinus sylvestris) seed orchard called Västerhus, located outside Önsköldsvik. In this seed orchard a tent experiment is taking place. Skogforsk has built six large tents covering 12-14 trees with each tent. Fertilization patterns were compared between one tree in a tent with a supplementation of pollen from five clones not represented in the tent and another tree of the same clone subject to open pollination outside the tents. By using DNA markers the paternity was determined for 48 seeds from each tree.

Teoretisk och experimentell utvärdering av Lättelement AB:s takinfästning

Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.

Våga Vara Annorlunda?: En uppsats om hur produktengagemang och motivation påverkar inkongruent marknadskommunikation

To be seen is essential. Presently, the marketing of different well-known brands within the same product category is done with little variation. To marketing professionals, this creates an opportunity to market products in an unexpected way. The use of incongruent market communication and by creating a discrepancy between a well-known brand?s advertisement and brand scheme, which is already established in customers? minds, is one way to be different.

Effekten av kvävegödsling på gasproduktionen vintertid i boreala sjöar

To investigate effects of nitrogen on in-lake CO2 and CH4 production during winter, three pair of lakes was subject for a fertilizing experiment in which one lake in each pair was fertilized with nitric acid (HNO3) directly into the water column in the summer of 2012. The lakes in each pair are assumed to be morphologically, hydrologically and biologically similar, that is, the non-fertilized lakes are considered references. The pairs do differ in one major way by being progressively less humic, going from around 25 mg/l to 10 mg/l DOC. Sampling and analysis was carried out at the end of the frozen period in 2013. Results show a significantly higher concentration of both CO2 (p<0,001) and CH4 (?=0,1, p=0,053) between impact and reference sites in the two less humic pairs.

Datainsamling med Web Usage Mining : Lagringsstrategier för loggning av serverdata

Webbapplikationers komplexitet och mängden avancerade tjänster ökar. Loggning av aktiviteter kan öka förståelsen över användares beteenden och behov, men används i för stor mängd utan relevant information. Mer avancerade system medför ökade krav för prestandan och loggning blir än mer krävande för systemen. Det finns behov av smartare system, utveckling inom tekniker för prestandaförbättringar och tekniker för datainsamling. Arbetet kommer undersöka hur svarstider påverkas vid loggning av serverdata, enligt datainsamlingsfasen i web usage mining, beroende på lagringsstrategier.

Flås, svett och inkongruens - En studie om effekterna av träning och tematisk inkongruens på annonser

Previous research about contextual effects on advertising has mainly focused on the editorial context, while advertisements' broader context has been overlooked. This paper aims to take a broader perspective on advertisement context. Its purpose is to get an understanding on how physical exercise influence the effectiveness of print advertisements, and furthermore to look at the effects of thematic incongruence between ad and the physical environment. We hypothesize that physical exercise increase ad effectiveness through affective priming and that thematic incongruence is beneficial for ads' effectiveness, especially after training when awareness about the environment is higher. A 2×2 experiment was conducted in a gym, where each respondent was exposed to either an incongruent or less incongruent ad, before or after physical exercise.

Spansk skogssnigel (Arion lusitanicus) i ensilerat vallfoder : betydelse för fodrets näringsinnehåll och hygieniska kvalitet

This work is about silage contaminated with slugs (Arion lusitanicus). The hypothesis was: Do slugs affect the nutritional value and hygiene quality of silage? During the winter season 2007/2008 silages were discarded in big amounts due to the contamination of slugs. Both the Swedish Farmer Association (LRF) and the National Veterinary Institute (SVA) received phone calls from farmers and animal owners about contaminated silage. The Swedish University of Agricultural Sciences (SLU) and SVA decided to initiate this project as a master thesis.

Varning! Effekter av varningar i printreklam.: Effekter av varningar i printreklam

The purpose of warning labels used by governments is to decrease consumption. In Sweden, the mandatory warning labels are designed according to statutory guidelines, and not according to research on attention-grabbing graphic elements. This results in a belief that the attention toward the warning labels is poor. An extensive experiment underlies this study, which has the purpose of providing insights to the effects that warnings, warning design, and warning content has on attention, attitudes and behavior in print ads. The study shows that, even though the standard design and content has lost much of its potential to communicate the warning, it gains more attention compared to a warning label with new design and content.
