Något händer när ny teknik gör intåg i klassrummet där undervisning, studier och lärande i olika ämnen står på schemat. I nästan varje elevs ficka finns idag en populär artefakt, mobiltelefonen. Att telefonen påverkar skolkulturen är förståeligt. Men hur anser lärarna att elevernas användning, kommunikationsrutiner och strategier för studier och lärande påverkar undervisningen och attityderna till skolarbetet? I skolan har man traditionellt alltid använt artefakter som myndigheterna har tillhandahållit, exempelvis böcker, penna och papper.

In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats. This study was divided in two parts. In the first part, it was examined if there were any differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.

The escalating usage of pyrethroids has resulted in an increased awareness about resistance towards pyrethroids in insects. Pyrethroids inhibit voltage-sensitive sodium channels (VSSC) in nerve cell membranes and are composed of synthetic molecules based on pyrethrins present in pyrethrum extracts from Chrysanthemum species. VSSC are transmembrane proteins that are important for electric signalling over the membrane in insects. Mutations in the gene encoding the sodium channel have proved to be a common reason for resistance against pyrethroids. Pyrethroid resistance among pollen beetles is spread all over Sweden and also abroad and is increasing.

Sjukvårdsrådgivning via telefon har blivit allt vanligare i västvärlden. Tekniska lösningar har utarbetas som underlättar för de döva att själva kontakta sjukvården via telefon. Sjuksköterskor inom primärvården kommunicerar då med de döva via text- eller bildtelefoni. Studiens syfte var att beskriva döva och sjuksköterskors erfarenheter och upplevelser av sjukvårdsrådgivning via telefon. Sex sjuksköterskor och fem döva intervjuades med öppna frågor.

Varför ökar antalet besök på folkbiblioteken medan antalet lån minskar? Syftet med den här undersökningen är att studera vad besökarna gör på Luleå folkbiblioteks huvudbibliotek och hur de betraktar sitt bibliotek. Frågeställningarna är: ? Vad gör besökarna på biblioteket förutom att låna böcker, tidningar och AV-medier? ? Hur betraktar besökarna på Luleå folkbibliotek sitt bibliotek? ? Vilka är det som besöker biblioteket? ? Hur är miljön på biblioteket och vilken inverkan har den på biblioteksbesökarna? ? Är biblioteket också en plats som lockar till sig andra besökare än de som söker det som förknippas med biblioteksverksamhet? För att kunna besvara frågeställningarna har en observationsundersökning och en enkätundersökning gjorts. I analysen har några begrepp från Bourdieu använts.

AimThe aim with this essay has been to investigate how preschools profiling in motor activity training, work to stimulate motor development of children. In order to study this, the main focus for the research has been on the following queries:What characterize motor activity training at the preschools studied?What is the purpose with the motor activity training of preschools which were studied?How do the preschools describe the affect that motor activity training has on children?How do the preschools look at the need for motor activity training?MethodFour in-depth interviews were conducted with representatives of the chosen preschools profiling in motor activity. My selection was based on a strategic sample and this was made by an internet mapping of preschool activities in the districts of Stockholm, and information from the service guide of the town of Stockholm. Then e-mail was sent to ten contact persons at preschool units, and ten preschools were contacted directly by phone.

In recent years e-commerce has experienced a big increase in usage. Internet however, cannot offer the same level of personal contact as traditional shops can.E-commerce is characterized by impersonal and standardized web shops that do not stimulate any emotional connection between the customer and the company. Without this personal contact with the customer the possibilities for the company to stimulate loyalty decreases. Loyalty however, is as important in e-commerce as it is in traditional commerce. The authors of this paper chose the following problem for the study:What marketing strategies are fortunate for e-commerce companies to use to create loyal customers?To research this subject the authors saw it fit to combine qualitative and quantitative research methods.

Product development is a risky business; many products never yield profit, but it is also ne-cessary for a company?s survival in a competitive business where the costumers change their requests constantly. Consumer-led product development is developed from the wish to fill the consumer?s needs and expectations and thereby be more likely to succeed. Lindell?s Gårdsslakteri AB is a local slaughter and meat processor in Västergötland.

Kroppens organ består av många miljoner celler, som har sin uppgift i det organ de befinner sig i. När en cell dör ersätts den med en ny som har samma uppgift. Cellerna samarbetar och kommunicerar via olika signaler, vilket är en förutsättning för att kroppen ska fungera. Cancercellerna delar på sig snabbt vilket leder till celltillväxt. cancer är den vanligaste dödsorsaken i Sverige, efter hjärt- och kärlsjukdomar.

The work covered in this report includes a literature study of the diesel dual fuel technology(hereinafter referred to as DDF). The literature study covers earlier work that has been doneregarding the use of compressed natural gas (CNG) and diesel in a DDF system. Moreover a onecylinder research diesel engine was fitted with a CNG fuel system for experimental testing. Theinstallation of the engine and the test cell is described. Results from the tests are presentedcovering emissions, heat release and pressure traces from the DDF-concept.During the literature study it was found that most research was related to heavy duty dieselengines.

The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens. Microorganisms have been extensively mined for their biosynthetic abilities to produce biologically active compounds. To date, more than 23 000 microbial natural products have been discovered. The Actinomycetales are ubiquitous bacteria that have been used for antibiotic discovery for more than half a century, and over 10 000 natural products have been identified from the order.

Begreppet ekosystemtjänster kan användas för att tydliggöra värdet av landskapets funktioner och därmed underlätta kommunikation mellan markanvändare då olika intressen konkurrerar. Emellertid finns det få studier som inkluderar en kvantitativ eller kvalitativ värdering av ekosystemtjänster på landskapsnivå. I detta arbete har markanvändning och ekosystemtjänster studerats i ett landskapsperspektiv, med Vilhelmina Model Forest (VMF) som studieområde. Den övergripande frågan i VMF är hur rennäring kan kombineras med andra markanvändningsintressen, huvudsakligen skogsbruk. Syftet med studien var att göra en kvantitativ värdering av markanvändningsintressen och ekosystemtjänster.

The most dominating channel for communication, connecting companies and customers, during the 1900 century was those who included either physical contact or phone contact. However, when Internet started to make its way as a channel for communication, a whole new opportunity opened up for the companies. Since then Internet has grown to be an important part for any company that wants to gain market shares. One of those markets is the market of travelling.This paper discusses the Swedish industry of travelling, and different travel organizers use of Internet as a mediate for long-term relationships. The paper is built on a comparison between three companies that all distributes journeys, this is to examine the Internet communications effect on the electronic relationship (e-relation) with customers.Three travel organizers with similar visions and objectives are compared in this paper, these are Apollo, Fritidsresor and Ving.
