Vaktelproduktion för ägg och kött

The aim of this study is to review the commercial quail production for eggs and meat in the world. Another aim is to review the potential for increased production. Globally the quail production is very small, except in China where it is the second largest poultry industry. The production globally is small despite the quail's rapid growth, early sexual maturity and its high feed efficiency. The quail is also used as a laboratory animal and can be reared to be released in hunting areas.

Utvärdering av substrat för biogasproduktion

The purpose of this study was to evaluate the different substrates that enter the digestion on Sundet wastewater treatment plant for production of biogas.This work have done an analysis of data about the biogasproduction from January 2012 to feburari 2013, this showed that the food substrates has a greater gas production than internal sludge.Through laboratory test the VS, TS and COD values for all the substrates used in the biogas production could be determinded. But the COD-method was less optimal for analysis of fat and food, therefore it optimized the method for fat but due to time constraints, this could not be done on the food substrates..

Opera i Stockholm : Stadsgårdskajen

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

Ståndortsanpassning och produktionspotential för björk i Gävleborgs län

Large amounts of birch-timber are imported to Sweden, from particularly the Baltic States, since the domestic production can?t support the pulp industry. The goal of this study was to show the potential of birch and the area?s most suitable for birch production. The study was limited to Gävleborg County. Using site characteristics, site index (SI) for birch was estimated on all National Forest Inventory plots in Gävleborg County.

Hur mår svensk filmmusik? : En kvalitativ studie av svenska filmkomposito?rers fo?rutsa?ttningar i det nutida produktionsklimatet

This thesis examines Swedish composers' modes of work and production within the Swedish film industry. It starts off with a historical overview treating live music in early silent film, the conversion to sound and the Swedish production climate until present time. The analysis consists of contemporary empirical studies; interviews with people writing music for film, TV and commercials. The musician's perspective is in focus but directors and other film workers are heard as well. The situation for female composers in a male-dominated industry is also discussed.

Storskalig mikroförökning av Malus domestica, Solanum tuberosum och Rubus idaeus i bioreaktorer

The importance of micropropagation has increased to provide the increasing fields with true to type and healthy plants. Traditional plants are growing on solid agar-based medium but lately liquid medium has become a new opportunity. This study has focused on a new bioreactor, developed on large scale micropropagation. Potato (Solanum tuberosum L. ?Semlo?), raspberry (Rubus idaeus L.

Adaptive Capacity through Complex Adaptive System

Problem: The corrugated board industry is highly affected by customer uncertainty, various demands and short delivery times. In combination with a complex multi-step production process managers have to be able to identify bottle-necks and gain knowledge and understanding of how different changes in process will affect the production output. <br/><br/>Purpose: The purpose of this master thesis is twofold, (1) to examine applicability of complexity theory through agent-based modelling on a production process (2) to identify improvement areas in order to increase the production output at SKS production site in Eslöv, by modelling and simulating the production process through an agent-based model. <br/><br/>Method: The chosen method of this study is a combination of a case study and a complex system approach. The empirical data was collected through interviews, observation and document studies which were analysed through an agent-based simulation model.

Utvärdering av skördetidsprognoser i vall :

Sammanfattning Ensilerat vallfoder är ett av de absolut viktigaste fodermedlen för att förmå korna att producera en stor mängd högkvalitativ mjölk. En hake är dock att ensilaget ska vara av god kvalitet och med bästa möjliga näringsvärde, samtidigt som man även vill ha volymmängder. För att få detta gäller det att skörda vid rätt tidpunkt, vilket kan vara svårt att veta när det infaller. Till detta finns ett hjälpmedel som kallas skördetidsprognos. Detta går ut på att man klipper prover i vallen upp till tre gånger innan första skörden för att analysera gräset och därigenom kunna avgöra när bästa tiden är för att skörda för att få den mest optimala kombinationen av mängd och näringsvärde. Syftet med detta arbete är att undersöka hur bra hjälpmedel jordbrukare i norra Sverige tycker att skördetidsprognosen är för att få en ökad kvalitet på ensilaget, samt att jämföra variationen i näringsvärde och mängd biomassa inom och mellan olika fält.

Miljödifferentierad fastighetsskatt

It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.

Påverkad strukturerad produktion produktiviteten? : Analys av mätningar från byggbranschen

The cost of construction projects have increased during the past few years. Different actors in the construction industry work together to advocate various measures to mitigate these cost increases. One of these measures is to try to improve the efficiency in the phase of production. By striving for a kind of standardization with a constant quest for improvement, the productivity can increase while the costs of production fall.For this thesis has a case study been conducted at the construction company JM AB which is seeking this. They call the approach structured production and have implemented various measures to achieve a more productive output.Based on information from reconciliations, the cost and the spent hours of craftsmen have been analyzed at the company where the case study took place.

Regionaliseringens effekter pa? svensk filmmusik : En kvalitativ studie av nutida filmskapares produktionsma?ssiga fo?rutsa?ttningar

This thesis examines Swedish filmmakers' modes of work and production within the Swedish film landscape. An introductory historical overview treats the Swedish regionalization since the mid 1990's. Political and economical aspects of producing films in various regions serve as a background for understanding the new generation of decentralised Swedish filmmaking, and the use of sound and music in contemporary film. The analysis consists of empirical studies; interviews with directors and producers, working with music for film and TV. Although the filmmaking perspective is in focus, composers and film scholars are heard as well.

Forsmark 3 ?Ett Framtida Biobränslekraftverk?

Recent turmoil surrounding nuclear power as an energy source, especially since the accidentat Fukushima, has largely contributed to the debate of whether or not nuclear power should beused as an energy source. This study has examined the economic feasibility of replacingForsmark?s 3rd nuclear reactor with a bio fueled power plant, and find out how this could bedone.The power generation that has to be replaced is equal to 1170 MWe. To replace this, 6 largescaleCFB-boilers, each providing over 200 MWe, were necessary. In addition to this, eachboiler required their respective turbine sets, comprising one high-pressure-, and one lowpressureturbine with intermediate reheating capacities.Based on this, a rankine-cycle was modeled using the software EES, to be able to calculatethe total heat required in the power plant.

Effekten av klimatförändringar påkontrollbehovet av åkerogräs

With a changing climate, we can expect higher temperatures and more precipitation in Sweden.As the temperature increases, new weed species are expected to migrate in from more southerlylatitudes, resulting in requests for new techniques for weed control. In addition, we might see agreater number of weed species and higher Biomass production due to increased concentrationof CO2 in the atmosphere.Increased understanding of the biology of specific weed species will become more importantin future weed control. This will help to control the weeds more efficiently. Higher prices onpesticides and a public demand for reduced use of pesticides make growers more inclined to usemechanical weed control on a larger scale and to a greater extent prevent weed establishmentbefore sowing. A well-planned crop rotation is the most important preventive measure, whichmight also include delayed sowing, and dark harrowing and sowing.Research takes place on many levels within the weed area and several alternative methodsare being developed.

Utveckling av förpackningssystem för torra insatsvaror i livsmedel

This project includes development of new packaging for dry spices and an investigation of how to automate the production line. The preliminary investigations show needs of an environmental friendly packaging possible to re-close. After screening for suitable materials three concepts were developed, a stand-up pouch, a plastic jar and a metal can. The pouch was excluded in a concept choosing process. In this process it was also decided to further develop the metal can concept.

Svensk plantskoleproduktion 2003 :

This work consists of two studies. One is based on an inquiery to nurseries with production of woody plants, and the other on visits to gardencenters, primarily in Skåne but also in Stockholm. Inquieries where sent to 87 nurseries, 48 of them replied. The purpous of the inquiery was to make a thorough investigation of the ligneous production at the Swedish nurseries, what is produced and in what quantities. Within the inquiery was also a thorough look at the fruit tree production. This to be able to conclude what cultivars that are produced and how large part of that production that is certified according to the Swedish Board of Agriculture (SJV).
