A recommendation for stand treatment of lodgepole pine (Pinus contorta) is, in a scientific point of view, lacking when it comes to harvesting for biomass energy. Within the next decades it is expected that 280 000 hectares of lodgepole pine will have reached thinning age on the domains of Svenska Cellulosa Aktiebolaget (SCA). Due to this the interest has grown rapidly for studying the possibilities of harvesting biofuel assortments already in the first thinning. In this study the distribution of the biomass within lodgepole pine trees has been studied and taken into account for estimating the proportions of harvested assortments when using different methods of thinning. The methods studied were conventional biofuel-harvesting (with delimbed branches gathered separately from the round wood) and thinning with cutting of round wood and long tops (incl.

Sheep breeding contributes not only with wool, hides, meat and milk but also with openlandscapes. The sheep?s wool is a good raw material thanks to a lot of different qualities as itis water rejecting and easy to form. The wool production today is concentrated to specificplaces in the world which leads to environmental problems and a distorted market. InJämtland, a province in Sweden, there is right now a staking going on for local production andrefining of wool in a project called Ullforum.

Denna uppsats behandlar problem med regelstyrd penningpolitik då hänsyn tas till osäkerhet kring kapacitetsutnyttjandet i ekonomin. Uppsatsen baseras på Taylors teorier kring ränteregler som säger att centralbanker bör sätta räntan utifrån förändringarna i BNP-gapet och inflationen. Sådana ränteregler har visat sig avspegla den historiska utvecklingen i räntan tämligen väl och har också använts som en referens vid utvärderingar för hur effektiv den förda penningpolitiken har varit genom kontrafaktiska simuleringar. Ett problem med dessa simuleringar och utvärderingar är att de oftast har använt slutgiltiga data för BNP-gap och inflation. Detta är dock inte helt rättvisande eftersom detta inte speglar den information som finns tillgänglig för beslutsfattare.

In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the fields, this is primarily used as feed for livestock. To get a good seed, you need to handle the crop carefully from planting to delivery. The part that I have been interested in, is how to dry the harvested seed with out destroying the growth in the small seed. This is very easily done if you aren?t careful during the drying period.

Background: The global responsibility for multinational companies is a current matter of subject. Now when the world increasingly is getting globalized, Economic growth is created, which brings a bigger demand of responsibility on companies. The leading companies from every industry is often becoming the frame for how the production process works and is therefore exposed to outer pressure which, for example, is coming from consumers and the media. Since consumers at present are more aware of what they are buying and where it comes from, it is important that the companies take social responsibility. We have therefore studied three big companies within the clothing industry to see in witch way they are taking their social responsibility.Purpose: Our purpose was to explore how companies within the clothing industry describe their work with Corporate Social Responsibility, code of conducts and where the incentive behind this work is coming from.Method: We have, through a qualitative study, examined how three large companies work with Corporate Social Responsibility.

There are records of lowering of the water level in a lot of the Swedish lakes from the middleof the 1700th century. The aim was gaining more areable land to meet the needs of more foodto support the expanding population. In areas with top soil which contents of clay or loam asin the southwest of Scania in southern Sweden this was proven to be a successful wayexpanding the total outcome of the harvest.The studied area in the northeast of Scania, though, consists of morain with a lot of mires -much less nutritious conditions. When the water level is lowered the atmosphere gets accessto the peat. The dissolving of the organic matter that has been suppressed by the lack ofoxygene below water level continues.

Livestock of pastoralists provide meat, milk, blood, dung and are useful for transportation purposes. In semi-arid and arid areas with very low precipitation the herder must often walk far distances to feed the livestock. This affects the animals? production, especially of milk. Previous studies have investigated how to improve milk production in terms of milking strategies in cattle.

All over the world the waste from human society is causing problems. In developing countries, large cities are polluted through huge amounts of wastes and people are forced to live very close to open deposits. Lima, capital of Peru, is no exception. The countryside in Peru has also a great challenge to face concerning the waste issue. Children and adults suffer from infectious diseases and contamination of the nature occurs as well. One solution to handle organic waste is to compost, which means a controlled decomposition of organic waste under aerobic conditions at certain temperatures.

The work aims to problemize and increase the understanding for the new labour market's flexible organising. By using Elias and Scotson's theory, the new organisational form of hiring doctors in healthcare will exemplify the developments taking place with many temporary jobs and how it affects the intrinsic structure of a work to be studied. The essay will focus on examining how the interaction affected between established nurses and new temporary doctors given the new form. How the interaction of the recently established group possesses a higher social-, economic- and cultural capital than the already established working group? The method is a qualitative study with three long and deep semi-structured interviews.

Ethanol for automotive purposes is an issue much debated and researchers disagree about the benefits of bioethanol. Converting energy-rich crops into ethanol suitable as motor fuel is a complex process and continuous development and improvements of processes and material used are important steps in the work of developing environmental friendly fuels. Grain is usually preserved by drying which consumes a lot of energy. Alternative storage of high-moisture grain in airtight storage systems reduce the energy required to produce bioethanol and studies have also shown that ethanol yields are increased more than 10% in ethanol fermentations of moist grain compared to dry. Airtight storage is often not perfectly airtight so biocontrol agents are necessary in order to preserve the grain.

Kenya is a country of 35 million people and is situated in Eastern Africa. 70% of thepopulation works within the agricultural sector and for many of them food insecurity is amajor problem. Maize and beans are today the staple food for many households. Goodfarming conditions enable two harvests per year and a potential maize yield of 4-5 tons perhectare.A major problem for many farmers in this area is the increase of the weed striga. The weedcauses severe yield losses, and has a major economic impact on smallholders.

This study attempts a literature based reconstruction of the impact of globalisation and modernisation on the gender identities in Vietnam. Recognising the explanatory albeit normative capacity of critical theory ? specifically the feminist and globalisation critical approach ? this thesis argues that in spite of the economic benefits of modernisation, it enhances existing unequal structures. By focusing on women in the labour sector, simultaneously Vietnam's comparative advantage and one of its economically marginalised groups, a contradictory movement can be discovered. Notwithstanding the economic development, a regression in terms of women's possibilities to self-empowerment seems to cancel the benefits for the individual.

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

The purpose of this study was to examine the threats from climate change coverage in the media. The climate threats start to appear more frequently in the media and because of that it is important to examine what the media conveys to the viewers and readers since it may effect how people act when it comes to climate threats. In this study newspaper has been examined, more specifically daily press and evening press. The papers chosen was Aftonbladet and Expressen, which represented evening press, and Dagens Nyheter represented daily press.The method applied was both a quantitative and qualitative text analysis. With the quantitative method variables were formed and tested against the material.

When the competition is getting stronger and companies must work harder to find new markets, new products and create new needs to reach growth, it appears strange that they overlook an obvious target segment right in front of their eyes. For some years ago, marketers of fashion brands feared that older women would wear their clothes, because it gave bad promotion for the young economically viable target group. Today, older women have difficulties finding clothes with right fit, style and personal taste. They would gratefully accept a brand, they felt were aimed for them. The purpose of this study is to give new ideas to companies in the fashion industry, how to reach this target group, but also be a contributing reason for older women to see the market opening for them.
