Timmersorteringens inverkan på sågverksekonomin :

Modern sawmills are using the raw-material and the production-capacity more efficiently today, due to rising raw-material prices and higher production costs. Log sweepness has a negative effect on the sawn yield, for sawmills with straight-sawing. It is desirable that these logs could be sorted based on more criteria, if it increases value-yield and consequently the utilization of raw-material. Bow-heights over 1 cm have a negative effect on sawn yield, since the surface of the mantle cuts down in the sawn pattern. Some of these small bow-heights reduce the logs yield of value which affects the production planning negatively. Nearly half of all the Swedish logs have a bow-height over 1 cm.

Flanksnitt som alternativ till linea-albasnitt vid ovariohysterektomi av tik :

In Sweden, the most common way to castrate a bitch is by midline approach. In this study, flank and midline approaches are compared in order to evaluate incision by the flank as an alternative technique for ovariohysterectomy in the bitch. The study was performed on straydogs in the central part of Thailand under field conditions. 32 bitches were included in the study. The castration technique was by flank and midline approach, alternating with every other bitch.

Hör träbränslena hemma i växthusen? :

With the elevated oil prices of today it is necessary to look for other heating alternatives. If the oil price continues to develop in the same way it has done the last years it will soon be impossible for many producing garden companies to survive. The purpose of this diploma work is to compare three different fuel options in order to find the most economic one considering the conditions of Katrinebergs Handelsträdgård AB. In relation to oil it is profitable to change to any of the three alternatives: wood chips, wood pellets and grain. The most profitable option is to change to wood chips. This alternative has a payoff time less than three years and after that the annual saving compared to the oil is relatively high. The annual cost is 65 % of the cost of the oil alternative.

Småskaligt vattenkraftverk i Nyköpingsån

Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.

Fermentation of lignocellulosic material by the alternative industrial ethanol yeast Dekkera bruxellensis

Bioethanol is one alternative energy fuel that can be produced from different types of biomass. Second generation bioethanol comes from fermentation of lignocellulosic material and can be seen as a more environmental friendly alternative as e.g. forest residues and agricultural by-products are used. To be able to use lignocellulosic biomass in ethanol production, it has to be subjected to different treatments first. In this study, aspen sawdust was used as lignocellulosic material.

Skolkod och pedagogisk förändring

Meeting the pupils at work it is important to endeavor an adjustment of the education with the purpose of developing the individual person. To make this possible it requires, except for the intentions of teaching with an individual adjustment, the teacher to make oneself acquainted with the schools work and liability. This is especially important in the work with students with difficulties. for this group of students perhaps an alternative form of education would be to prefer.As method of investigation I used a qualitative case study with a teacher who uses, what I would call, an alternative way of teaching. as a teacher you should pay attention to, and be aware of, how you effect your pupils and with this as a starting point conduct oneself.

Managementperspektiv på grisproduktion i Lojsta :

At the farm Fride, in Lojsta at the Southern part of Gotland, my family runs a pig production with 80 part-integrated sows in a ?Familybox-system?. The main parts of the facilities are from the early 90´s and have done their job. The production results have the last years decreased because of new infections so we have to do something before shifting ownership! This degree thesis is meant to answer the question about which the optimal extension would be today. By studying literature, use my own experience and make lots of calculations, I try to find out different opportunities.

Förortens paradox : En kritisk analys av mediala representationer

There are several typical ideas about the suburb. The suburb is often associated with criminality and other social problems such as segregation. The purpose of this essay is to study the picture of how the suburb is constructed in a media context. The method used to answer the purpose of this study is critical discourse analysis, based on the thoughts of Norman Fairclough. The central theoretical ideas for this study are representation, stereotypes and racialization.

Lönsam mjölkproduktion : en fallstudie

Ravelsmarks gård have now reached the stage when there are few options for the future. The options are either a construction of completely new farm buildings or a winding up of the milk production. Present on the farm today there is 65 dairy cows plus recruitment. 44 cows stand in long-stalls and 20 cows stand in short-stalls. The objective of this study was to examine the profitability of a completely new cowshed. In order to get costs for investments different milking systems and equipment for feedstuff have been compared. The systems in the investment budget have been chosen on recommendations from advisers, salesmen and on the basis on what is suitable for the farm. One system where a so-called mix feeder wagon is used for the roughage seemed to be best suited for Ravelsmark. The different prices obtained for the manure well show that there are possibilities to decrease the investment costs.

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.

Delat ansvar för ett enat Sri Lanka: asymmetriska relationers påverkan på fredsprocessen

Since 1983 the people of Sri Lanka has endured an ongoing Civil war, however the intencity has varied over the years. The aim of this theses is to examine what influence the asymmetric relationship between the Sri Lankan goverment and the Liberation Tigers of Tamil Eelam (LTTE) has on the process of negotiating a solution to the civil war. I am also examining whether the asymmetical relationship has changed over time and if these changes have had any effect on the process.To analyze the asymmetries I divide them into material and non-material. I measure the material asymmetries in economic and military resourses, and to measure the non-material I use indicators such as commitment, alternative, controll and legitimacy.The results show that the asymmetrical relations between the parties in Sri Lanka have changed since the 1990s. Factors like 9/11 and the recurrent suicide bombings by the LTTE has had a great influence on the singalese-tamil relationsship.
