This thesis has been carried out at Diac Metal AB at Torsvik outside of Jönköping. The company produces parts for, amongst others, office furniture and store equipment. The essay will be concentrated on one detail which is included in many of their products.Today the company uses an ordering quantity based on experience which is rarely updated. Furthermore the operations are performed in both the company?s own engineering workshop but also an external workshop.The purpose with the report has been to check whether an updating of today?s batch shaping and ordering system can mean simpler storage control and possibly cost reduction.

Conducting research on allergy isproblematic since it has genetic, as well as enviromental, determinants.ObjectiveThis thesis attempts to conclude and evaluate research on a connection betweensupplementation of omega-3 during pregnancy and allergic outcomes in infants and children.Search strategyThe literature search was conducted in the databases PubMed and Scopus. Among thekeywords chosen were omega 3, supplement, pregnancy and allergy.Selection criteriaHuman RCT, that measured allergy, where the intervention consisted of supplementation withomega-3 for at least ten weeks during pregnancy and ceased at birth.Data collection and analysisThree articles were chosen for this thesis. The articles were examined using templates fromSBU and the quality of evidence was evaluated according to GRADE.Main resultsNone of the articles showed a protective effect on allergic outcome but in one of the studiesthere was significant reduction in eggallergy and another showed significant lower occurrenceof severe eczema.ConclusionsSupplementation with omega-3 during pregnancy does not occur to have an protective effecton allergic outcome in infants and childen but the evidence for this is considered to bemoderate.

Introduction: A complex interaction between muscles, tendons, bones, joints and nerves are required for optimal function of the human hand. It is known that an individual?s grip strength is vital for performance of physical demanding tasks such as strength training with free weights. Strength training including a thicker grip around the bar may enhance the strength of the grip in the athlete without other special routines for grip strength development. The purpose of this investigation was to examine the difference in performance in multiple repetitions in two strength training exercises using two different sizes on the bar, to look for correlations between grip strength of the subjects hand and the amount of repetitions executed with two different size of the bar and finally the correlation of hand size and the amount of repetitions executed with two different size of the bar.Method: 15 strength training men (23,9 ± 4,1 years), underwent measurements of hand size, maximum grip strength, 1 repetition maximum (1RM), a 80 % of 1RM weight strength test with two different  bar sizes.Results: The results from the present investigation indicates a 21,1 % reduction of 80 % of 1 RM weight performance in repetitions executed in the bench press with the thicker diameter of the bar and a 66,2 % reduction in repetitions executed with a 80 % of 1 RM weight in the lying bench row with the thicker diameter of the bar.

Product development is essential for all companies that want to survive in competitive markets regardless of the characteristics of the product that the company sells. Companies that sell products within product categories which can be seen as bad, also need to develop their products in order to remain competitive. If these bad products add a positive attribute, for example that they get organic, a contradiction within the product arises and they get incongruent. This thesis investigates which effects that follow a launch of an incongruent product. The thesis also examines if these effects are affected by the strength of the brand under which the product is launched.A total of 240 respondents participated in an experimental study where product incongruity was manipulated for two different product categories, where one well known brand and one unknown brand were examined in each category.

Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.

The idea of using algae in different areas and exploring its possibilities is nothing new. Already in the early 1950s microalgae was explored as a possible food resource because of its high protein content. Lately there has been an increased interest in its potential for industrial use. Wastewater treatment is a possible use of algae since the algae grow well on the nutrients present in the water. This offers the possibility to grow algae for nutrient reduction and use the biomass for energy or animal feed since many alga species has a good nutritional value. Approximately 800-1000 m3 water is applied per 1000 m2 of greenhouse area during one season in a tomato production.

The aim of this study is to find information about what to do when riding arena footings are worn-out. Especially, the surface layer of riding arena footings is very interesting because of its importance of giving grip in every step for the horse, as well as shock ab-sorption. Generally, surface layers are containing several different parts in order to achieve desirable properties. These different parts can consist of organic material or in-organic material (mostly gravel). Gravel and many other materials in the top-layer are environmental friendly, and therefore, easy to get rid of.

Syfte: Att analysera hur dagligvaruhandeln använder sig av Grön Marknadsföring internt och externt för att positionera sig som ett miljövänligt företag på marknaden.Metod: En deskriptiv undersökning med primärdata i form av personliga intervjuer från de tre största aktörerna inom svenska dagligvaruhandeln.Teori: ?Green Marketing Activities at the Three Levels? har används som modell för att ta reda på hur de olika företagen arbetar med Grön Marknadsföring. Modellen är uppdelad i åtta områden och tre nivåer för Grön Marknadsföring.Slutsats: Samtliga företag vill ta ett miljöansvar, men två av tre ser sig även ha ett ansvar att informera och hjälpa kunder till ett bättre handlande. Två av de tre undersökta företagen är mer inriktade på att bygga ett ekologiskt varumärke medan det tredje företaget är mer inriktad på att upplysa om ekologi. Undersökningen visar dock att alla aktörer har undermåligt arbete med marknadsföringen i butik för att fånga upp kunders ekologiska intresse.

The poultry red mite, Dermanyssus gallinae, is a common problem in poultry facilities, causing great discomfort for the hens and effecting the production economically. Few efficient acaricides are available and there is a need for new control methods since resistance has become a problem in some cases. The aim of this study was to evaluate the efficiency of the new liquid silica control agent Ectopar, on the poultry red mite. An initial in vitro test of Ectopar and its two components individually was performed, where live mites were sealed in together with filter paper impregnated with one of the three solutions prepared. The survival of the mites was thereafter recorded repeatedly during a period of 120 hours and compared to a control. For the field study, two poultry farms with different housing systems were used, one with furnished cages (farm 1) and one with a single tier floor system (farm 2).

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Does low fat dairy products reduce blood pressure?Author: Emma Bergman and Naman LimaniSupervisor: Lena HulthénExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 26, 2014Background: It is estimated that at least a third of the population in Sweden have a high blood pressure with genetics, unhealthy diet and physical inactivity as the main contributing causes. High blood pressure is one of the greatest risk factors to develop cardiovascular diseases, which is the leading cause of death worldwide. Milk is a nutritional food product and previous research suggests that low fat dairy products may have blood pressure lowering effect.Objective: The aim was to examine the scientific basis of how low fat dairy products affect blood pressure.Search strategy: Twelve searches were conducted on PubMed and Scopus, where the chosen search terms were combined to produce a broad search as possible in the particular area. The search terms used were dairy, dairy products, milk, blood pressure and hypertension.Selection criteria: Studies on normotensive or hypertensive individuals who received low fat dairy products were included.

Kommunalt avloppsvatten innehåller stora mängder föroreningar bland annat organiskt material som påverkar organismerna i naturen. Reningsverken runtom i Sverige arbetar ständigt för att minimera utsläppen av föroreningar. Det är viktigt att kontinuerligt analysera vattnets kvalité för att kontrollera reningsverkets funktion. Total Organic Carbon (TOC) och Chemical Oxygen Demand (COD) är två analysmetoder som används för att mäta organisk halt i avloppsvatten. Från COD-analysen uppkommer farligt avfall som innehåller kvicksilver varför analysmetoden enligt EU-direktiv ska fasas ut.

Ground construction has to a large extent been dominated by traditional meth-ods during the last 50 years. Although the construction has been changed meanwhile innovations are not accepted. In collaboration with NCC Ltd Region South, I have examined a modern con-struction methodology that has been developed by NCC for future large pro-jects. The method is divided into two central phases. Phase 1 is? Single Pro-duction? which is a preliminary period for ground constructions to come.

It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).

The popularity of vegetated, or green roofs, has grown over the past years due to their potential function of maintaining urban environment quality. The aim of this study was to investigate if substrates with different organic material, peat and charcoal, with two contents (3 or 6 weight%) influenced the growth of the cuttings during the first critical period of the establishment. Biochar is used as amendment to agricultural soils and has, theoretically, many of the properties suitable as organic content in green roof-substrates. Peat is one of the materials that is commercially used in green roof industry. The substrate has been treated with different amounts of water.

This paper is to identify and analyze a new trend which we believehas taken off, based on qualitative interviews and analysis of three productions which we have been involved in during a practiceperiod of two months with a production company in Stockholm. This essay intends to define this trend as an organic formation of digital material and to identify the key characteristics which form the basis of how to create a production of this nature..
