Poultry producers? perceptions of changing market conditions : a field study of the poultry production in Khartoum state of Sudan

Sudan has always showed great potential in the poultry industry, but it has not been until now that this potential has blossomed and is growing quickly. As large agribusinesses1are taking over the market shares within the urban areas, smallholders2 have been put out of business. They are not able to compete with mass production and lack financial assets to improve their production techniques. Contract farming is defined as initiatives from agro industrial companies to secure access to smallholder produce and has in developing countries become a way of allowing the poor to participate in a larger market (Farrington, 1999). The aim with this study was to investigate the suitability of implementing the contract farming concept within the poultry industry in Sudan today. The study is a qualitative field study and the authors have conducted qualitative interviews with respondents involved in the poultry industry in Sudan.

Ståndort och växtval på takterrasser

In the country of Jordan, egg production is very important economically, but several bacte-ria are involved in food borne diseases transmitted from eggs or other poultry products. The most important are Salmonella spp., Campylobacter jejuni and Escherichia coli. In Jordan two different housing systems are used for hens in large scale egg production; con-ventional cages and litter floor systems. Eggs from four different farms were analysed and compared to see if a difference could be found regarding the presence of pathogenic bacte-ria on the egg surfaces between these two systems. Total number of aerobic bacteria was analysed, the presence of Salmonella spp., C.

Anläggning av traditionellt VA-schakt : En fallstudie i logistik och byggstyrning

A growing issue in the construction industry is how production can become moreefficient by using logistical solutions. Companies can minimize the cost of a project byreducing the time to perform the work.The purpose of this report was to examine the logistics related to pipe trenches forSIAAB. The report's focus has been on solving problems and planning that wouldfacilitate the work of the project Vaksala-Lunda Etapp 3.The case study consists of interviews with SIAAB's employees and an observationwhere the progress of a traditional pipe trench has been documented using checklists.Questions to the report?s case study come from the theoretical part, which is basedon literature on construction management and logistics in general. The observationlasted five weeks and the biggest time-consuming events that affected the pipe trenchduring this time, has received most attention.

Industrialisering av konsumentprodukt : Från inkommande material till färdigvarulager

This report examines the industrialization of a newly developed household machine on behalf of Technogarden Engineering Resources in Karlstad, Sweden. The report is a part of the final course in the Bachelor Program in Mechanical Engineering at Karlstad University and takes place in spring 2014.An innovator, an investor and a engineering consultant firm have through collaboration developed a new type of gruel machine. The product is in its final stage of construction and is planned to be manufactured in a production located in Sweden, autumn of 2014.To compete against today?s trend in outsourcing manufacturing to low cost countries for better profitability, the industrialization of the gruel machine must be done with a minimum amount of resources in order to become successful, which also describes the problem of this study. Using pre-study material in form of Lean production literature, visiting a successful production site and gathering data from involved engineers a specification was developed which describes what this industrialization must achieve and which requests can be accomplished.

Balansering av vindkraft och vattenkraft i norra Sverige

This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.

En Samtida Opera. En empirisk studie av Giuseppe Verdis "Don Carlos" utifrån två fältstudier.

This research looks into the modern revival of opera based on the study of two recent productions of Giuseppe Verdi?s Don Carlo; the first is the 2010 production at the Gothenburg Opera in Gothenburg, Sweden and the second is the 2013 production at Großes Festspielhaus in Salzburg, Austria. The goal is to discover what aspects a contemporary audience can relate to and identify with and why opera is still relevant today. This has been done partly through a semiotic analysis of the visual image (e.g. set, costume and lightning) and partly through a hermeneutical analysis of the themes in Don Carlo.

Export of wood pellets from British Columbia : a study about the production environment and international competitiveness of wood pellets from British Columbia

The global wood pellet market has seen a rapid growth after the adoption of the Kyoto protocol and the renewable energy incentives created within the European Union. The global consumption of wood pellets reached 13,5 million tonnes in 2010 and several experts estimate the consumption to be between 35-50 million tonnes by 2020. These forescasts raise the questions which regions that can supply this vast amount of wood pellets and what the conditions are for producing it. This study evaluates the conditions for wood pellet production and export from British Columbia, on Canada?s west coast, focusing on existing industry structure, raw material supply and the distribution chain.

Analys av det nordiska kraftnätets påverkan på det svenska elspotpriset.

During the last few years, there has been a lot of debate regarding the price ofelectricity on the Swedish market. According to a recent survey from Sifo, anon-bias governmental institute for consumer research and testing, the priceof electricity is what worries Swedish households the most. An investigationof the eciency of the Nordic power grids inuence on the Swedish spotprice is therefore both relevant and valuable. Three quarters of all electricityproduced in the Nordic region is traded at the Nord Pool Spot power market.This survey examines how much of the variation of the swedish spot pricecan be descried by the variation of the nordic system price and how much iscaused because of ineciencies in the power grid. Primarily, linear regressionwith adjustments for endogeneity and heteroskedasticity has been used in orderto analyze data obtained mainly from Nord Pool Spot and Vattenfall AB.The results show that the variation of the system price can account for all butabout 40% of the variation in the Swedish spot price.

Arbetsprestation, samarbete och sammanhållning i påfrestande arbetsmiljöer: en fallstudie inom beroendevård

Stress is commonly found in society today. This paper aims to examine how work performance, cooperation and team spirit are maintained in demanding work environments. By studying two departments in a public hospital that practises addiction care, our findings suggest the following: If the experienced stress is mainly connected to challenge stressors, it has a positive effect on work performance. By organising work through mechanistic and organic structure, the handling of qualitative and quantitative stress is facilitated. As a consequence, first and foremost cooperation can be maintained, but also work performance and team spirit.

Industriella metoder för platsgjutna vindkraftverksfundament

Bakgrunden till denna rapport är det stora antal vindkraftverk som det idag finns planer på att bygga i Sverige. I Jokkmokksliden utanför Malå i Västerbotten påbörjades byggnationen av en vindkraftverkspark under 2010 vilken kommer att bestå av 18 vindkraftverk ritade av en tysk konstruktör. Fundamenten för vindkraftverken är massiva gravitationsfundament där armeringen är särskilt komplicerad att montera och kräver en stor arbetsinsatts. Syftet med denna rapport är att undersöka om och hur man genom att tillämpa nya metoder och planeringsverktyg kan öka produktiviteten och därmed minska arbetsinsatsen. För att uppnå detta har en djupstudie inom Lean Production utförts.

Kvävemineralisering från stallgödsel beroende på olika grad av inblandning i mark

The impact of the distribution in the soil volume of two farm manures on the net mineralization and immobilization processes of nitrogen were studied in an incubation experiment. Cattle slurry and broiler litter were placed in the soil with three procedures for incorporation including placement on top of the soil (TOP), in the middle of the soil (MID) and mixed homogenously with the soil (MIX). During the two weeks of incubation, few significant differences in net mineralization were seen between TOP, MID and MIX. However, there was a tendency that MIX led to a larger net immobilization of N than placement at one point (TOP and MID). This is also the result in the literature.

Förändring i färdigvarulager och utlastningen av foder efter införande av en ny produktmix : En fallstudie på Lantmännen Agroetanol

This Master thesis was written for Lantmännen Agroetanol in Norrköping concerning the layout of their finished goods inventory and unloading of feed after introducing a new product mix. Lantmännen Agroetanol has two production lines which produces feed. Both lines lead to six silos, used as inventory of finished goods. The feed from the two production lines differ in terms of quality, where as Lantmännen Agroetanol wants to separate their finished inventory in order to charge a higher price, by selling the better product as a premium. With two different feed products the yearly revenue is expected to increase which motivates a research about the current capabilities and necessary changes to be made in the factory.

Materialhantering i en produkt- och volymmässigt varierad verksamhet: En fallstudie vid GE Healthcare Umeå

I den konkurrensutsatta tillverkningsindustrin är det viktigt att ha effektiva processer för att kunna hålla nere kostnader och samtidigt hålla en hög kvalitet för att kunna erbjuda attraktiva produkter till konkurrenskraftiga priser. Lean Production är en produktionsfilosofi vars fokus är att eliminera alla former av slöseri som inte skapar värde för kunden. Ursprunget till Lean Production kan härledas till fordonsindustrin och det japanska Toyota Production System. Systemets tanke byggde på en effektiv produktion för att kunna möta konkurrensen från större amerikanska konkurrenter som kunde dra nytta av storskalsfördelar i sin massproduktion. Ett av inslagen i Toyota Production Systems var att lagra material i nära anslutning till produktionen i så kallade supermarkets.
