Species diversity and geographical distribution of Fusarium species on winter wheat in two regions in Sweden

Various Fusarium species causes some of the most common cereal diseases worldwide. Besides the yield losses that can be a result of these diseases, strains from several Fusarium species can produce mycotoxins, some very toxic. The aim of this study was to investigate which Fusarium species and how many that occurred in winter wheat grains from Mälardalen and Kalmar län, if there was any difference in the distribution of Fusarium fungi between the regions and the potential within species to produce mycotoxins belonging to the group trichothecenes. Winter wheat grains collected in 2009 from ten fields (unsprayed plots) in the two regions were analysed for Fusarium species. PCR was used to amplify the TEF region where after the samples were sequenced.

Sortimentsinriktad avverkning

Forest enterprises have always searched for ways to improve efficiency. For the past few years there has been an emphasis on stock-keeping levels. Increased demand for fresh round timber and the need to decrease the amount of tied-up capital has made the forest industry reduce its inventory levels. This has brought on a higher demand on the timber supply from the forest management districts concerning both delivery in time and assortment output. As a result, the flow of timber has fluctuated a lot with serious consequence for the timber supply during 1994.

Fördröjning och bortfall av nätverkskorrektioner : osäkerhetskällor för nätverks-RTK

Network RTK is a real-time technique for accurate positioning with Global Navigation Satellite Systems (GNSS). The technology means the use of correction data from a network of GNSS receivers with known positions (reference stations) to reduce the uncertainty in position for the user´s GNSS receiver (rover). However, this requires that the correction data can be transferred seamlessly to the user in real time. Commonly the corrections are transferred via mobile phones. The Swedish National Land Survey operates a nationwide Network RTK service, where users can receive correction data via GSM or mobile Internet (GPRS).

Laborationsmätning av vindtäthetens betydelse för en väggs U-värde

To fulfill the climate target that EU and the Swedish government have decided to apply, it becomes increasingly important that the energy efficiency of existing buildings and making new buildings energy efficient as possible. Of Sweden?s total energy consumption in 2011 was 40% used by residential and service. Of the 40% of the energy consumption was 60% used for heating and domestic hot water. A report from year 2012 shows that one reason why the heating volume is so great could be due to underestimating on the energy consumption for the heating in the planning of the building.

Storbankernas kreditprocess efter finansiella kriser : En undersökning av åtgärderna som gjorts i storbankernas kreditprocesser efter en finanskris

Bakgrund och problemdiskussion: Bankkrisen under 1990-talet och den globala krisen mellan 2007 -2009 har kommit som en kalldusch för de svenska storbankerna, Handelsbanken, Nordea, SEB och Swedbank, vilket har lett till betydande kreditförluster. Kreditförluster är den vanligaste orsaken till bankernas ekonomiska problem vid en finansiell kris då återbetalningsförmågan hos kredittagare försämras, samtidigt som det talar för att finansiella kriser är ett återkommande fenomen idag.Syfte: Syftet med detta examensarbete är att se vilka åtgärder i kreditprocessen som gjorts efter finanskriserna i de fyra svenska storbankerna samt även se hur tidigare gjorda åtgärder stod sig under den senaste krisen. Vår ambition med uppsatsen är att de resultat vi får fram ska kunna användas av bankerna i kreditprocessen så att de påverkas mindre vid framtida eventuella kriser.Metod: Uppsatsen grundar sig på en kvalitativ metod med respondenter med gedigen erfarenhet och ansvarspositioner inom storbankernas kreditprocesser och praktisk kunnighet gällande storbankernas påverkan av finansiella kriser.Slutsats: De svenska storbankernas kreditprocesser stod sig bra under den senaste globala krisen i jämförelse med bankkrisen under 1990-talet, orsaken till det är de åtgärder som gjordes i kreditprocessen efter bankkrisen inom banken. Kreditprocessen har under de senaste 20 åren gått från en delvis oprövad och snabb kreditprocess till att idag vara en mer sofistikerad och tungarbetad kreditprocess som ställer högre och strängare krav på kredittagarna. För att få kreditprocessen helt vaccinerad mot finanskriser anser vi att det behövs mer mod och integritet hos kredithandläggare för att på bästa sätt kunna förmedla den rådande situationen på ett korrekt och snabbt sätt..

Bergkyla och bergvärmeutredning för industrilokalen Rödbergsmyran 5 i Umeå, Västerbotten.

Grubbe Ventilation AB is a sheet metal and ventilation company who provides design, installation, service, and repair of ventilation. The company is expanding their business by building a new facility in Umeå, Västerbotten. The property is designed to be used for both office and industrial work.Grubbe Ventelation AB has not yet decided upon wish system which is to be established to provide the building with heating and cooling. The consulting firm Umeå Projekt Team has therefore been asked to investigate the possibilities to invest in geothermal- heating and cooling.If the investigation of a geothermal heating- and cooling system would provide favorable results it would be a very appropriate alternative that provides energy at low costs and are an environmentally friendly option as the energy comes from stored solar energy in the ground is provided by stored solar energy in the ground.The facility ´s heating and cooling consumptions are calculated in the program BV2 and the result indicate a heating demand of 185 000 kWh per year due to thermal transmittance, transmission losses, heating of warm water and a cooling requirement of 5500 kWh.Three different systems of geothermal heating and cooling were tested in the computer program Energy Earth Design. The results show no difference in the dimensioning of the drill hole if merely heating were to be used or both heating and cooling were to be established.

Soil fertility status and Striga hermonthica infestation relationship due to management practices in Western Kenya

Striga hermonthica, a parasitic weed, has long been believed to be correlated with the declining soil fertility status. However scientists have recently come to question this statement since some recent studies have shown contradictive results. To investigate whether soil fertility status and infestation of Striga hermonthica were correlated and the impact of it were caused by farmer management, 120 farmers in Western Kenya, where Striga hermonthica infestation is prone, participated in this study. In three districts with two sub-locations each, farmers answered a structural questionnaire and identified two fields, one with high and one with low soil fertility. These fields later came to be the basis for this study and soil were therefore also sampled from them.

Bedömning av fallrisk hos patienter som vårdas inneliggande på sjukhus och inom kommunal vård : Med hjälp av Downton Fall Risk Index

Background: Fall injuries are a costly problem for society, with costs ranging up to 14 billion a year. In addition to economic loss accidental falls also creates human value losses and reduced quality of life for its victims. In order to prevent the occurrence of injury related to accidental falls healthcare providers utilize various scientifically developed risk assessment tools, one of them being Downton Fall Risk Index. Method: Empirical, quantitative cross-sectional study. Objective: The purpose of the extended essay was to describe the categories in Downton Fall Risk Index that have a bearing on patients' risk of falling while in hospital and in municipal care, and to illustrate how nurses can use the fall risk assessment tool.

En undersökning av specialpedagogiska perspektiv inom ridterapi

Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

Femtio Nyanser av Co-branding - En kvantitativ studie om effekterna av co-branding på konsumenters varumärkes- och produktutvärdering beroende av kvalitetssegment och hedoniska shoppingmotivationer

The retailing industry has an extremely high density of brands. In order to differentiate its offer, both retailers and suppliers, are constantly forced to come up with new ways to launch their products. A collaborative strategy between two brands is called co-branding, which means that both the private label and the supplier's brand are displayed on the new product packaging. Several studies have shown that a co-branding strategy is successful, but many operators are still reluctant to use co-branding in fear of long-term losses due to potentially damaged business relations. The objective of this study is to explain how the product- and brand related value for customers, retailers and suppliers is affected by co-branding between private labels and national brands.

Utvärdering och optimering av sidoströmshydrolysen vid Duvbackens reningsverk

I Sverige förekommer strikta krav på fosforrening av avloppsvatten och detta har bidragit till att kemisk fällning har kommit att dominera som reningsmetod för fosfor vid svenska avloppsreningsverk. Fällningskemikalier är dyrt för reningsverken att köpa in och ger negativ påverkan på miljön vid tillverkning och transport. Strängare reningskrav har ökat behovet av nya reningsmetoder som på ett effektivt och miljövänligt sätt kan rena avloppsvatten från näringsämnen utan att kostnaderna för reningen blir för stora. Biologisk fosforavskiljning (bio-P) utnyttjar mikroorganismer som naturligt kan ackumulera fosfor i sina celler. En kritisk faktor för en väl fungerande biologisk fosforavskiljning är tillgången till kolkälla i form av flyktiga fettsyror (VFA).

Metoder för lastprioritering i fjärrvärmecentraler

A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.

Spillningsinventering för bestämning av älgbetesbelastning på ungskog

In the 1980?s the moose population in Sweden grew explosively due to big changes in the silviculture with clear cuttings instead of single-tree selection. Clear cuttings brought big areas of young forest and therefore a lot of fodder in one place. Since this change, the discussion about how to manage the moose population has grown into a very big problem. Forest owners think that the population needs to be strongly reduced because of all the damage that is done to the young forest when the moose seeks its food, and the economic losses because of that.

Papper åt alla! En diskussion om post- och transnationalitet i dialog med den spanska sociala rörelsen för papperslösa migranters rättigheter.

The aim of this paper is to expand the debate on globalization and its consequences from a theoretical perspective emphasizing social processes of exclusion and inclusion. I explore these social processes in dialogue with the Spanish social movement for the rights of irregular immigrants. The paper also aims to explore new forms of resistance in the context of globalization."The declinist thesis" argues that globalization has lead to a declining importance of the nation-state and the national citizenship as guarantees of rights. "The anti-declinist thesis" oppose to this picture arguing that rights still depend on national policies. I also discuss the functions of exclusion and inclusion inherited in the concepts of citizenship and nation-state.I outline the historical and political context of the movement and explore the ideas and organizational dimensions of the movement's "knowledge praxis".I conclude that national citizenship - in a broader sense as a description of the relationship between the individual and the state - seems to play a crucial role in the life situation and the possibilities of irregular migrants to organize and protest.
