Droppbevattningens inverkan på kvalitet och kvantitet hos Solanum tuberosum L i jämförelse med konventionell spridarebevattning :

A literature study and a field trial have been carried out in order to investigate the physiological response of potato plants to different soil moisture levels. Higher yield, quality and number of tubers can according to the literature be obtained if constant high soil moisture is kept during major parts of the growing season. A field trial was set up where drip irrigation was used as an alternative to conventional irrigation techniques to maintain high and constant soil moisture. The application of water in the drip irrigated area was monitored and adjusted on a daily basis so that the soil moisture stayed as close as possible to the recommended level. The sprinkle irrigated area was irrigated according to traditional practices with approximately 35 mm every 7th to 10th day depending on the whether.

Kassationer på ett livsmedelslager - Effektivisering och kvalitetssäkring av processen för intern kassation i enlighet med Lean Production

Today's fierce competition means that companies constantly must develop their business and internal processes. Focus on processes and continuous improvement is something that characterizes Lean Production which ICA logistics are applying with their concept Leading Logistics. Standardized routines for handling damaged gods were insufficient at the ICA distribution center in Kungälv. Handling and registration of damaged gods were not performed uniformly, resulting in problems with controlling and monitoring the process.The purpose of this thesis was to analyze and make recommendations how the process of internal handling of damaged gods could be improved. Therefore a comprehensive understanding was needed of the entire material flow through the warehouse and important quality aspects such as product safety and delivery reliability.The methods used are literature reviews, interviews and observations to produce a comprehensive process mapping of the current situation at the distribution center.

TOC and TQM Utilized in a Mass Customization Production Environment

Background: Mass customization has been identified as a competitive business strategy by both companies and academics because of its ability to incorporate the voice of the customer into companies? products and services. Although mass customization may sound appealing, the strategic concept is still developing and firms adopting this business strategy face several challenges. Production concerns are of high relevance since mass customization implies a high level of customer involvement in the product design. Since the areas are closely linked it is reasonable to ask how a mass customization strategy affects production concerns.

Effekterna av att signalera hög annonskostnad för ett välgörenhetsföretag - ett undantag från tidigare forskning om signalteori

In today's fast-paced, intense and complex media environment, it is hard for non-profit charity organizations to reach out and get their messages heard.In this study we examine whether the theories of advertising signaling also applies for charities. Past studies of the signaling theories indicates that higher perceived advertising expense leads to more positive effects on purchase behavior and brand perceptions. However, we believe that this does not apply for a charity organization. We argue that since charitable organizations have a fundamentally different mission than commercial companies, they will need different ways to signal quality and credibility, and therefore the common signal-theories will not hold for these organizations.To test our hypotheses, we conducted two surveys where the respondents saw one of five versions of the same ad for a well-known Swedish charity organization, or one of two ads for a commercial corporation. The ads had been manipulated to simulate different levels of perceived cost.Our results shows that perceived ad cost only affects attitude towards the ad if a charity was the sender, whereas perceived ad cost affects intentions, attitudes and credibility if a commercial corporation was the sender.

Det fria ordets makt: En kvantitativ studie om effekten av kommentarer i anslutning till artiklar på nyhetssajter. Vad händer när elektronisk w-o-m blandas med traditionell pr?

This thesis treats the topic of user-generated comments connected with news stories on news sites, meaning electronic word-of-mouth combined with PR. The writers have examined how different types of comments affect consumers' perception of the article and also what communication effects these comments generate in terms of attitudes, purchase intent and word-of-mouth intent. The results interesting to the news site owners, is that lots of comments and negative comments generate a negative effect by making the actual article less credible, attractive and worth reading (relative to the subsequent comments). On the positive side, serious comments imply that the news story is perceived as more interesting, than a news story followed by non-serious comments. From a brand equity perspective, the interesting results show that few comments compared to lots of comments, generate a better attitude to the brand, even though there is no difference in how positive or negative the comments are.

Kvalitetsprocesser och mätning av pinnfräsar : ? Empirisk studie av produktionsmätutrustning vid frästillverkning

This master thesis investigates quality procedures and measuring of solid carbide end mills, with the main focus on measuring equipment. The thesis has been written in collaboration with a special production department for solid carbide end mills at Sandvik Coromant in Gimo. The department?s needs and constraints have been the foundation of the project and the main research question is: how to measure end mills in order to ensure good quality of the produced end mills. The project has contained both a theoretical study consisting of a literature review and practical studies in the workshop with the objective to identify an end mill?s main parameters and the relationship between an end mill?s geometry and the manufacturing processes.

Att organisera för lärande : En studie av samband mellan gruppens ålderssammansättning och förutsättningar för barns lärande i förskolan

Syftet med denna studie är att undersöka om det finns några mönster och samband i hur förskolepedagoger upplever förutsättningar för barns lärande beroende på ålderssammansättningen i gruppen. Studien är kvantitativ med webbenkät som metod för insamling av data från pedagoger. Undersökningen omfattar alla förskolor inom en kommun i Värmland, totalt 55 kommunala avdelningar och 144 pedagoger. Följande ålderssammansättningar ingår i studien: åldersindelade grupper, småbarnsavdelningar (1-3), avdelningar för äldre barn (3-5) och syskonavdelningar (1-5).Studien har sin utgångspunkt i interaktionistiska teorier, vilket innebär att förskolans verksamhet studeras utifrån olika samspelade aspekter, faktorer och nivåer. I studien ses förutsättningar för barns lärande i förhållande till förskolans kvalitet, vilken i sin tur tolkas som ett komplext fenomen som skapas i samspel mellan olika faktorer på struktur-, process- och resultatnivåer.

Potatisens specifika vikt och kokegenskaper med hänsyn till odlingsplats och sort :

The boiling properties are an important quality issue of the potato. In order to obtain adequate boiling properties the growth of the potato needs to be controlled and interrupted at the right time. However, it is difficult to determine when to stop the growth. Specific gravity can easily be measured and can sometimes be used as a tool for estimating the boiling properties. This report discusses different aspects of the specific gravity of the potato and how it can be used as a tool to determine the appropriate time for vine killing.

Planteringsförbandets inverkan på bestånd av contortatall (Pinus contorta var. latifolia) med avseende på volymtillväxt och virkesegenskaper

At the beginning of the 1970´s forestry feared an imbalance in the future wood supply. Because of this anticipated "timber slump" forest companies undertook a variety of measures to counter this. One of these measures was the introduction of exotic tree species. The choice finally ended up with lodgepole pines which were considered a fast growing tree species compared to our native tree species. Theambition for the new lodgepole pine stands were to run these with rotation periods of between 40-60 years, thus smoothing out the ?timber slump? that was anticipated.
