Planering & produktionsstyrning : Lean filosofin vid produktion av asfalt

Lean is a production philosophy which is about increased resource use while meeting customer requirements. The foundation of lean comes from Toyota and their production philosophy The Toyota Way. Professor Jeffrey k. Liker has worked with Toyota's production philosophy and Lean for a long time and has created a 4 P model and 14 principles that characterize the Toyota production system (TPS), which many sources refer to.The aim of my work is to study the working procedure of asphalt projects from sales to the laid asphalt with a focus on planning and production management. The goal is to examine how the lean philosophy can be applied in planning and production to simplify the flow of asphalt projects based on Likers model and principles.

Teknik för egen foderberedning :

There is an uncertainty in the market for grain forcing the meat/milk producers to review alternative feeds to a larger extent, in order to get control over the feed costs. This has led to that the meat/milk producers need to have a good knowledge regarding how the different feeds influences the animals and which technical equipment to use for handling. For those that produce their own feedmix, there is a need to put interest in new crops and their characteristics to be able to get the knowledge of what is required for their own production. It is beneficial to keep an open dialogue with advisors to be updated in new crops and new technology for feeding. When mixing feed at farm level, the legislation is not very clear since it the target group is large scale mixing plants. We have brought up the most important rules and regulations from the EU parliament Council as well as the ones from the Swedish Board of Agriculture (SJV), regarding feed mixing on farm and factory level. We have studied beans and pea at two different moisture levels, in order to evaluate how the moisture level affects the distribution of particles when milling with a plaitmill and a hammermill.

Kombinerad produktion av biogas och biodiesel på gårdsnivå : en investeringsbedömning ur ett ekonomiskt och miljömässigt perspektiv

Syftet med detta examensarbete är att göra en investeringsbedömning av en anläggning för kombinerad produktion av biogas och biodiesel åt lantbruksföretaget Lindhs Djur & Natur AB. Utgångspunkt är det koncept för kombinerad produktion av biogas och biodiesel på gårdsnivå som Ageratec AB utvecklat. Konceptet utgår från att glycerolfasen som bildas vid biodieselproduktion är ett värdefullt substrat vid biogasproduktion. Scandinavian Biogas Fuel AB har därför på uppdrag från Ageratec AB utvecklat och optimerat en biogasprocess för samrötning av glycerol och gödsel.För att kunna göra en relevant investeringsbedömning så granskas investeringen både ur ett ekonomisk och miljömässigt perspektiv. Den ekonomiska analysen består av en investeringskalkyl för två olika amorteringstider där teorier för nuvärdesanalys tillämpas.

Vetlandas gatuträd : analys av trädens upplevelsekvalitéer

Street trees have had a prominent role in Vetlandas history from the turn of the century up to present day. Many trees have unfortunately been taken away through the ages, but most of them luckily remains and most of the streets in central Vetlanda are still tree lined. The comprehensive inventory that has been made shows that lime is the dominant species in Vetlanda with no less than 62 %. The age division is quite even with one peak at the turn of the century, one during the ?60s and another during the ?90s.

Alternativ till obedövad kastrering av smågrisar : - Ur ett ekonomiskt och djurhälsomässigt perspektiv

This degree project aims to evaluate alternative methods to the unanaesthetized castration of piglets. Castration of piglets is performed to prevent the development of boar taint. Boar taint can cause great financial losses for the pig manufacturer. Unanaesthetized castration of piglets is not regarded to be satisfactory from an animal welfare perspective and the procedure will for that reason be outlawed in the near future.Several alternative methods are used in countries all over the world with promising result. The purpose of this study is to evaluate if this methods could be applied in Swedish pig production.A literature study has been combined with interviews; field studies, questionnaires and a small study on male pig production.To be applicable to and applied in Swedish pig production the alternative method must be financially accepted by the manufacturers but also accepted from an animal welfare perspective.Castration is the only way to guarantee a meat free of boar taint.

Local poultry production in rural Zambia and the effect of light on poultry performance

Zambia is a country in Southern Africa where poverty is widespread and the traditional keeping of local poultry therefore plays a crucial role in improving nutrition. Meat and eggs from poultry are important sources of protein but also of income. Improving the poultry production is thereby a method to fight poverty. For poultry, the access to light is an important factor for both growth and egg production. In this paper, the focus is on the traditional village chickens used for both egg and meat production, how they are kept, their health and welfare and if the use of a solar lamp will influence their behaviour, growth and egg production. Three studies were conducted in Chibombo and Choma Districts in Zambia were 17 farmers were interviewed regarding the village chicken management of which six farmers participated in a solar lamp experiment.

Värmebehandlat trä ? att inhämta synpunkter i produktutvecklingens tidiga fas :

This study is a part of a Swedish research and development project that is about heat-treated wood and is led by the Swedish University of Agricultural Sciences and Luleå University of Technology. Products that are heat-treated already exists on the market, foremost the Finnish brand ThermoWood®, bur the project group want to find out if it would be possible to start a Swedish production with somewhat different applications than what is common today. The heat-treated wood has many attributes that have changed in the heating process. It becomes more biologically durable, it gains stability in form and dimensions and it becomes darker and looses several unwanted extractives such as resin. Disadvantages that can be mentioned are that the wood becomes fragile and the strength properties changes. My main purpose with this study is to look into customer involvement in the early phase of product development. I also want to find out if the customers I interview think that the product is worth working with, which means start a Swedish production.

Miljöpåverkansbedömning vid tillverkning av etanol från cellulosabaserade råvaror : ekologisk gård självförsörjande med drivmedel

Fuel produced from renewable resources is of big interest. In this project the difference between a few different renewable materials are compared on the matter of environmental load when ethanol is produced. The renewable materials that are compared are Salix, straw and reed canary-grass (rörflen). The cellulose in the material is cut down to small pieces and then hydrolysed so that the sugar from the cellulose can be fermented into ethanol. Tha amount of ethanols that is studied in this work is the smount of ethanol needed to cultivate 1000 ha. The functional unit in the report is 1000 ha.

Prevalens och genetisk karaktärisering av afrikansk svinpestvirus i vektorer och tamsvin i Uganda

African swine fever, ASF, was first described 1921, in Kenya. The virus has thereafter spread through many African countries as well as in Europe, Asia, South- and Central America. The virus is spread via three different cycles, of which one is sylvatic and includes warthogs and soft ticks. The other two are between domestic pigs and the one most common one is caused by humans, who not always realize the seriousness of precautions. The infection manifests as hemorrhagic fever, but can also be more or less unnoticed. The aim of this study was to use molecular tools to detect and partly genetically characterize ASFV both in soft ticks and in serum from domestic pigs in Uganda. Comparing viruses detected in ticks with those detected in domestic pigs I also wanted to investigate possible links between the sylvatic and domestic cycle.

Biogaspotential hos rejektfraktionen från biogasanläggningen Kungsängens gård

Den totala biogasproduktionen i Sverige 2009 var 1,4 TWh och 22 % av biogasen producerades i samrötningsanläggningar. Sedan 2005 är det förbjudet att deponera organiskt avfall, vilket har gjort att produktionen från samrötningsanläggningar har ökat de senaste åren. Den totala biogaspotentialen i Sverige är ungefär 15 TWh och där står lantbruket för över 70 %. Avloppsslam, avfall från livsmedelsindustrin och matavfall står för den resterande delen. Det är även dessa tre råvarugrupper som har störst lönsamhet med dagens teknik.

Fossilfria godstransporter : En undersökning av alternativ till diesel som drivmedel för lastbilar

Our modern society is in many ways built with and dependent on fossil fuels, which are used for energy production as well as for transporting humans and goods. Without the oil, many of the things we take for granted would not be possible. During the last century, the use of oil has increased steadily and will probably keep increasing as the world population and the economic well-being for many people increase. Since the oil is a finite resource, we will have to find other fuels that can replace it if we want to keep the same rate of development in the future as the availability of petrol fuels will decrease with rising prices as a result. Furthermore, fossil fuels have the disadvantage that they produce harmful emissions when combusted and thus affect the climate and air quality locally and globally.
