En ödmjukt auktoritär rådgivning : Ethos och etik hos föräldrarådgivaren Petra Krantz Lindgren

Wermland was affected by the Spanish flu like the Swedish national average, about a half percentage of Wermlands population would lose their lives to the flu during the autumn 1918. The flu has for many fallen into oblivion. This oblivion is so wide spread that it´s possible to talk about a "collective forgetfulness". The society have selected to remember 1918 for "when the guns went quiet on the western front" and not for the millions who died from the treacherous Spanish flu. The world had already suffered enough from the four years of war that had been fought, thus the victims of the flu would be honored but would soon fade in to oblivion.  When you investigate deeper you get the picture that the national average don´t do Wermland and its cities or rural areas any justice when a large variations seems to occur within regional areas.

TOMO Hugglink

Tomo Hugglink (TOMO Skog) is an innovation for Harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

Analys av framtida potential för virkesköp från privata skogsägare i Västerbottens län : beslutsunderlag för virkesköpsstrategier

This study was conducted on behalf of SCA forest AB, Västerbottens forest administration. Timber procurement from non-industrial private forest owners has become an increasingly important part of SCA:s wood supply. The objectives of this study was to report the current forest conditions in the private forests in the county of Västerbotten, analyse the potential for procurement of wood from private forest owners, and provide a basis for decisions on future strategies for timber procurement from private owners.Material and data have been collected from different sources, mainly from Swedish National Forest Inventory and SKA-VB08. This material was the basis for the analysis and calculations performed with the Heureka application PlanWise. This study area was divided into six different analytical areas (Coastal south, Coastal middle, Lycksele, Inland south, Inland north, Skellefteå), where each area of analysis is represented by a number of municipalities.In this study, two scenarios were specified; one describing the current forest management with current Harvesting levels and the effects of these assumptions, the second to illuminate what potential there is for future timber Harvesting.

Skogsbränsledrivare i klen förstagallring med contorta

The aim for the study was to examine a harwarder´s (combined Harvester-forwarder) productivity when Harvesting forest fuel in first thinning stands that contains Lodgepole pine and calculate the economy of the Harvesting work and estimate the quality of the thinning . The field study area where located near Arvån, about 15 kilometres south ?east from the city of Lycksele. The field studies were taken place in three different stands. All tree stands had the same tree age, but the tree species combination and the density varied.

En ekonomisk hållbar växtodling i sörmländsk mellanbygd :

We have been looking at three different types of agriculture in Södermanland, in the middle east of Sweden. We call the different types for Intensive, Extensive and Mix. The purpose is to get an economic defensible plan for how to run different farm sizes. We also have been looking at the working hours and how many hours the different types will give. We have a farm called Taxinge Gods as our pilot farm. Taxinge Gods grow 407 ha land and is located 60 km southwest from Stockholm.

Tidsstudie av containerhuggbil

The fork lifter chipper truck is a concept which has been developed for Harvest and transport of bio fuel. The system consists of one fork lifter chipper truck and 1, 2 or 3 transport lorries, usually two, which serves the fork lifter chipper truck. The system is driven by the fork lifter chipper truck that produces chipped material into a container on the truck. When the container has been filled the truck drives to the landing site where it?s offloaded.

Proteinkvalitet och biogena aminer i ensilage ? effekt på mjölkkors hälsa & foderintag

The aim of this paper was to explain protein degradation in silage and protein quality and biogenic amines in silage and their effects on the health of the dairy cows. After Harvest-ing, the plant proteases degrade the proteins in the plant. The protein degrades to different fractions with different digestibilites in the rumen. Fraction A contains non- protein nitro-gen which is peptides, free amino acids and amines. True protein is in the fraction B and is further divided into three subfractions depending on their solubility.

Majs till mogen skörd :

Corn is an important food and feed crop in the world, in Sweden it?s up till now grown on limited acreages mainly for silage. But I think it can get more important if you can grow it also for grain, because it?s a good animal feed for example, for life stock-, pigsand poultry. On of corns advantage is that it can produce the same amount of dry matter as for example wheat, barley and rise but with 25% less water. I will examine if it possible to grow corn for grain production in the south of Sweden.

Försäljning av närvärme :

To provide our company a new business opportunity I have in this essay examined the economical possibilities to sell energy. I have chosen to do a case study on my own farm in this essay. The farm is focused to cropping and also have some properties for hire. The farm is situated in the village of Fjelie and that?s where the opportunity for selling heat are. Fjelie has about forty houses. The idea is to build a plant where straw is being used as fuel.

GROT uttag i Värmlands Län : Extraction of Harvest residues in the County of Värmland

På uppdrag av skogsstyrelsen skall beräkning av framtida potential för uttag av skogsbränsle (GROT) vid slutavverkning av skog göras. Skogsbränsle utgörs till stor del av GROT som är avverkningsrester i form av GRenar Och Toppar. Flera faktorer påverkar hur mycket skogsbränsle det blir vid uttag efter avverkning. Stora snabbväxande träd har en större gren- och barrmassa. I detta arbete har lämplig mark, beståndens ålder och sammansättning selekterats ut med hjälp av GIS för att erhålla största möjliga volym GROT.

Kylkedjan för snittblommor - en kartläggning av distributionen

Title:Chillchain for cut flowers ? how the distribution works.Author:Anna-Maja Svarén, student at Lund Institute of Technology, mechanical engineering.Supervisors:Annika Olsson, Department of Design Sciences.Bengt Sahlberg, Bioett AB.Problem:How does the distribution of cut flower works regarding temperature, losses, responsibility, complaints, packaging and weak points?Purpose:The purpose is to map the distribution of cut flowers, with focus on losses in the temperature, from farm to store. The goal is to identify weak points in the chillchain and to se how wrong temperatures affect the flowers. The results can be a help to secure the chillchain.Method:The work started with a problem; map the distribution of cut flowers with focus on temperature losses. Data was collected on the basis of this problem, then analysed, and finally conclusions were drawn.Conclusions:The affect handling and distribution has on a cut flower is very complex.

Frigörelse av kvicksilver och metylkvicksilver till bäckvatten under olika perioder efter skogsavverkning :

High levels of Hg in fish in Swedish lakes have been a problem along time in Sweden. The major concern is production and accumulation of the most toxic form of mercury; methyl mercury (MeHg). Consequently, in about half of our 83 000 lakes fish contain concentrations above the recommended limit for human consumption of 0,5 mg mercury per kg fresh weight (most of it in the form of MeHg). Consumption of fish containing too high levels of MeHg may cause problems for both humans and animals. Three major sources of MeHg in surface waters are: 1) runoff from terrestrial areas, 2) deposition from the atmosphere, and 3) internal production of MeHg in lakes and streams. The aim of this study was to investigate the effect of clear-cutting on the concentration of Hg and MeHg into draining streams.

The impacts on Indian farmers when converting to organic cotton production : an organisation theory perspective

Changes in the environment are affecting the world market, and pressures from several stakeholders? are forcing different enterprises to adjust to the current situation. Farmers? difficult working conditions and environmental impacts of the conventional cotton production in India have been highlighted. The small-scale production that is characterising India?s cotton farmers implies an insufficient competition power.

Potatis, marknad och konsumtion i dagens Malmö :

I want to find the meaning of food ?potato in today?s society. How about marketing and how does potato consumes? What can be done to achieve better competitiveness towards other products now and in the future? I will build this project on a statistic ground ?now and then? as well as a study to people outside various food- markets. The consumers answers will state my foundation in this project.

Bäddodling av matpotatis :

This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes. Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient. In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.
