Obtaining high quality textile fibre from industrial hemp through organic cultivation

AbstractThe urgency to find alternative fabrics to conventionally produced cotton is increasing as vast amounts of agrochemicals are used and a lot of irrigation is required. In this literature survey the potential of organic cultivation practices to produce highly qualitative hemp fibre, suitable for the textile industry, was investigated. The definition of a fibre in the textile context as well as of the qualities that are essential for a textile fibre was necessary as a base for the discussion in this thesis. The quality parameters looked at were fineness, strength, length, friction, and colour. The impact of external growth factors and plant development on these quality properties are discussed.

Produktion av finfibrig ull genom avel och utfodring - inkorsning av merino i sveafårsbesättningar :

To produce fine fibre wool as a complement to lamb meat production, Merino and Svea sheep are currently being crossbred in the county of Jämtland. The aim of this study was to evaluate growth and wool quality of the first crossbred lambs. In addition, a literature study about nutritional effects on wool production has been carried out. The literature study showed that fine fibre wool should foremost be achieved through directed breeding. Nutritional requirements of the sheep at different stages of production should determine their feeding.

Flerskiktat papper : en sammanställning av historia, teknik och forskningsresultat

Until the beginning of the 1900:th century the paper making process was handicraft. The paper machines that have been developed since then are as impressing in size as fascinating when it comes to the technique. The process has always been improved to give a better paper for lower costs, with as short manufacture time as possible. Stratified forming has been a reality since 1830. From the beginning it was applied to board and paperboard.

Dietary fibre composition and sensory analysis of heat treated wheat and rye bran

When grains of wheat and rye are conventionally milled, large quantities of bran classified as by-products are left and are mainly used for animal feed. Bran is a complex material composed of the aleurone layer, nucellar epidermis, a seed coat, a fruit coat and a small proportion of the germ and endosperm depending on extraction rate. The bran fraction consists of approximately 40-50 % dietary fibre which can contribute to increase the nutritional quality of human cereal food. It would also be valuable for the food industry to convert by-products as bran to products with higher commercial values. The aim of this thesis was to analyse the content and composition of dietary fibre of heat treated wheat and rye bran according to the Uppsala method with some modifications in order to analyse soluble and insoluble dietary fibre separately. Half of the bran samples were precooked, dried and roasted and the other half dried and roasted (uncooked).

Whole grain wheat : effects of peeling and pearling on chemical composition, taste and colour

The EU-project HEALTHGRAIN has suggested a new definition for whole grain which allows a small part of the grain to be removed during processing. By removing the outer part or the grain the hygienic quality will increase but it is not clear how the taste and colour is affected. So therefore in this study three different debranning methods, peeling, pearling and polishing, which remove the outer parts of the grains have been used on common and durum wheat. The dietary fibre and ash content, as well as germination was analysed in untreated, peeled, pearled and polished grains. The decrease in dietary fibre and ash was higher in grains that had been pearled compared to those that had been peeled or polished.

Renen och nötkreaturet, en jämförelse mellan två olika typer av idisslare :

The aim of this literature review was to make a comparison between the feeding requirements of Swedish reindeer (Rangifer tarandus tarandus) and meat producing cattle (Bos taurus) within farming. Reindeer are an intermediate feeding type; they have the ability to adapt to short term seasonal changes in food. They avoid eating fibre as much as possible and display highly selective behaviour while foraging. Adaptation to harsh environments with a limited amount of food has made reindeer dependent upon easily digestible food and consequently their digestive systems are less capable of processing plants with high fibre content. Herding is an extensive system which requires a significant amount of land and labour and describes the reindeer industry.

Tritordeum : evaluation of a new food cereal

Tritordeum is the result of a cross between a wild barley (Hordeum chilense) and durum wheat (Triticum turgidum). Tritordeum have high viscosity and a nice yellow colour. The objective of this thesis was to evaluate Tritordeum lines HT 354, HT 361, HT 437, HT 2218 (JB3) and HT 1608 (JB1) for use as a new raw material within the food industry. Analyses made were on dietary fibre, fructan, ash, water content and colour. Compilation of data from analyses made for Agrasys an Agri-Food company in Barcelona having the commercial rights to Tritordeum, included Lutein and rheological properties.

Kvalitetschefens Roll och Kompetens Inom Svenska Organisationer och Företag

The role of the quality manager has evolved from being a quality controller to work with a more global business. Within many organizations in Sweden, however, the traditional role of the quality manager's remains and the tasks categorized as quality control still takes up most of the quality manager's time. The survey conducted as part of this master thesis shows that the quality manager in most businesses has multiple roles in addition to the role of quality manager, which can create a role conflict. One consequence of this is that each improvement is not given priority due to time constraints. Although the importance of a clear and committed leadership is the key for succeeding as the quality manager.

Effect of insoluble fibre enrichment on egg quality in laying hens

Studien var en del i ett större projekt som syftade till att undersöka hur värphöns påverkas beteendemässigt och nutritionellt av ökad konsumtion av olöslig fiber. I det nu aktuella projektet undersöktes hur ökat intag av olöslig fiber påverkar äggkvalitén. Fiberkällan utgjordes av halmpellets som antingen blandades i fodret med 3 % inblandning, alternativt utgjorde strömaterial för att undersöka strömaterialets betydelse som fiberkälla. Två olika hybrider ingick i försöket, 720 Lohmann Selected Leghorn (LSL) och 720 Lohmann Brown (LB), varav halva antalet av varje hybrid hölls i frigående system och andra hälften i inredda burar. Totalt insamlades och undersöktes 180 ägg från varje inhysningssystem då hönorna var 31-32 veckor gamla.

Vallfoder till slaktgrisar : effekter på tillväxt och social beteende vid utfodring

The aims with the project were to investigate how forage consumption affect production and pigs behaviour around the feeding. This degree project was designed to follow 48 growing/finishing Hampshire*Yorkshire pigs, from 30-110 kg live weight, fed diets with or without 20 % forage inclusion. The pigs were divided in three groups due to dietary treatment. In the first group the pigs were fed 20 % of the energy in the feed ration by long grass/clover silage (LE) and the remaining 80 % by a cereal concentrate. Group two was fed chopped grass/clover silage mixed with cereal concentrate (HE) in the same amounts as LE.

Var det värt det - Hur prisnivå påverkar uppfattad kvalitet, prisvärde och kundnöjdhet

The purpose of this paper is to examine the effect that price has on quality expectations and customer satisfaction and how price fits into a customer satisfaction model. An experiment in which participants are subject to scenarios of a high or low quality flight are used to test the hypotheses. The analysis shows that perceived quality has a bigger impact on satisfaction than price. Furthermore, price and quality do not affect customer satisfaction independently of each other. The importance of value compared to quality changes whether the actor is a high or low price actor.

En förstudie till kvalitetsutveckling på GD-tryck

The print- and mailroom at Gefle Dagblad (GD-tyck) is handling an increasing amount of commercial jobsalong with the newspaper production. Investments have above all been done in the mailroom to be able tooffer commercial costumers a higher degree of finishing and there are plans to expand further in the commercialmarket. GD-tryck is of the opinion that they need to secure the quality of their production to be ableto do such expansion, which is the reason why a quality system of some kind may be appropriate. Howeverthere are no plans to certify such a quality system according to ISO 9001:2000.In this exam report the present methods of working have been analysed from a quality perspective.Suggestions on how GD-tryck should be working with quality development is presented in the fields whereshortage of quality has been discovered. The suggestions taken together do not form a quality system butcan be looked at as ideas of approach to quality fields that have to be developed if a working quality systemshall be accomplished.Many of the quality fields that have been discussed do not have anything to do with technical qualitydirectly but are in some degree requirements for a working quality system.

Kvalitetssäkring av tjänsteinköp

Quality Assurance in Service Procurement --- Total Quality and Total Quality Management refer to popular management philosophies in organizations these days. The purchasing department has an important part in the strive for organizational quality as several studies show corporate spend is significant and increasing. In this master thesis I study the actions companies take to ensure quality in service procurement. I argue that managing quality when sourcing services is particularly tricky, because of the special characteristics that belong to services. The purpose of the study is to examine whether different actions are taken to ensure the quality of different kinds of services.

Att säkra farmor - En komparativ fallstudie av kvalitet och kvalitetssäkringsarbete inom äldreomsorgen

The care for the elderly in the municipalities has recently seen the need for a formalized system for quality assurance. Under increasing demands for monetary efficiency while bound by law to retain acceptable standards in health care, there is need for efficient and at the same time quality-assured management. The municipalities often solve this puzzle by introducing systems and standards influenced by theory-clusters such as NPM (New Public Management), TQM (Total Quality Management) or other quality management theories.This essay focuses on how the public administration in the municipalities defines quality and designs and implements system for formalized quality assurance. Our basic view of organizations is institutionalist and our theoretical framework includes theories about quality, NPM and TQM..
