Energy investments in new buildings are not longer a small part of the energy saving program. Long-term investment demands needs large knowledge and awareness about the energy topics that have recently grown in the municipal real estate companies.

Effect of Bacillus mediated priming on different natural genetic variants of Arabidopsis thaliana

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

Case Pöyry Sweden AB : Miljöprestandaindikatorer för ett tjänsteföretag

The world's natural resources are constantly being reduced, which increases the pressure on companies to actively engage themselves in environmental activities. Meanwhile, stakeholders focus is being broadened and it is now important not only to supply a particular product or service but also show that they are actively pursuing an environmental agenda. Companies can use various tools to aid in environmental efforts, but also to demonstrate to the world that the company is actively engaged in environmental activities. One such tool is the environmental standard ISO14001 which provides the company with guidance and support on how the business must manage its environmental efforts. To show a business' progress in environmental performance, it is advantageous to use environmental performance indicators as they enable stakeholders to easily understand how the business works with environmental issues.Authors in the field explain that the environmental management system propagation is limited in service organizations.

Marknaden för skogsvårdstjänster : en undersökning bland privata markägare inom en region i Värmland

This work broadly illuminates the conditions for increasing the commissions of forestry services within the whole, or parts of, the western regions of Stora Enso?s operating area. Through a questionnaire, a survey was made examining whether the owners of the forests themselves do the forestry on their woodlands. This foremost concerns the pre-commercial thinning, but also planting and soil scarification. The survey also shows who are buying the most part of their forestry services and who are carrying it out themselves.

Bostadssektorns koldioxidutsläpp

Energy is an important issue in the current world which significantly affects sustainability and development. Energy generation and use are major sources of CO2 emissions which is one of the most important driving factors in global climate changes. The amount of energy used in house hold section can lead to estimation of the amount of CO2 emitted within this section which subsequently would be a ground to better management and maintaining a sustainable society. This study which is a bachelor?s project in sustainable energy, deals with estimation of CO2 emission from different types of residential houses in Sweden. An extensive literature review on energy use in Sweden by different residential sectors has been conducted.

Strategisk analys av den svenska byggbranschen- En studie av JM, NCC, PEAB OCH SKANSKA

Background: The construction industry is Sweden?s single most important industry branch with a significant influence on Sweden?s wealth. The political restrictions that once controlled the industry are today almost gone. This combined with an unbalanced supply and demand situation on the Swedish constructions market, caused by urbanisation, has led to increased pressure on the Swedish construction companies who now are forced to find new methods in their struggle to contain or increase their competitive advantage. Purpose: The purpose of this thesis is to survey: which strategic variables are of great importance in today?s Swedish construction industry with focus on the four main actors, JM, NCC, PEAB and Skanska.

Luftvärnets utveckling sedan millennieskiftet : En studie av de bakomliggande faktorerna

Uppsatsen tar sin utgångspunkt i antagandet att det svenska luftvärnet under 2000- talet har haft en begränsad utveckling och att truppslaget inte har följt den internationella trenden med mer högpresterande system. Syftet med uppsatsen är att försöka förklara vad som har drivit det svenska luftvärnets utveckling och vilka faktorer som lett till att luftvärnet idag ser ut som det gör.Graham Allison klassiska verk Essence of Decision har utgjort den teoretiska referensramen som legat till grund för undersökningen. Luftvärnets utveckling har studerats utifrån perspektiven om Rationellt beslutsfattande och Maktutövat beslutsfattande.Resultatet av undersökningen visar att Allisons teorier är gynnsamma för att studera drivkrafter och förklara luftvärnets utveckling. Det maktutövade beslutsfattandet kan till stor del klargöra utvecklingen men har visat sig sakna fullständig förklaringskraft. Perspektivet kan därför med fördel nyttjas för att ge en alternativ bild av utvecklingen men inte ensamt förklara drivkrafterna bakom.

Grazemore DSS för att prediktera beteskvalitet för mjölkkor :

The aim of this study was to examine if the predictions of the herbage quality in the software Grazemore Decision Support System (DSS) gives a reliable ground for milk production in the north of Scandinavia. Pasture samples from one research farm (Umeå) and one organic farm (Nordingrå) was analysed on crude protein and organic matter digestibility. The results were statistically compared to the predicted values. Measured and predicted herbage mass was compared and a control if the predictions of milk production improved if the predicted input were replaced by the values from the analysis, was made. The concentration of crude protein was underestimated by the model on both farms and the relationship between actual and predicted values was poor. Mean Prediction Error (MPE) was 24% and 31% respectively.

KOGNITIV PROBLEMLÖSNING UNDER STRESS : PÅVERKAR FYSIOLOGISK AROUSAL PRESTATIONEN?

Förmågan att prestera under akut eller kraftig stress är en förutsättning för en del yrken. Forskningsresultaten gällande hur stress påverkar prestation pekar åt olika håll. Denna studie undersökte sambandet mellan fysiologisk arousal och kognitiv problemlösningsförmåga under stress. Trettiotvå polisstudenter testades på Ravens test av flytande intelligens APM set II både före och efter att antingen ha sprungit i tjugo minuter eller haft en självskyddslektion på ca fyrtio minuter. Resultaten från en mixed ANOVA för beroende mätningar visade på en signifikant interaktionseffekt (F (30) = 6,547, p < 0,05) ? en ökning i prestationen hos självskyddsgruppen med arton procent och en minskning med femton procent hos löpningsgruppen.

Vad innebär planeringstid? : En kvalitativ studie om fyra förskollärares syn på den pedagogiska planeringen i förskolan

The running of a Swedish pre-school is not just about taking care of children but involves incorporating educational activities that follow curriculum guidelines. In addition, time must be allocated for planning, discussion, evaluation and reflection. Many pre-school teachers feel that there is insufficient planning time which is needed to follow the established curriculum guidelines for kindergarten. Due to the rising numbers of children per class, and the obligation to document and evaluate everything, pressure and lack of time has become a significant issue.The purpose of this study is to investigate four pre-school teachers´ views on pedagogical planning and reflection time. Questions to be answered include:1.

Miljö i fokus - En studie av de bakomliggande drivkrafterna för den ökade miljömedvetenheten inom svensk kemiindustri

BACKGROUND & During the last century, the Swedish chemical industry has developedPROBLEM: considerably in regard to respecting the environment. Following various discharges and pollutions during the first half of the 20th century, environmental concepts such as CSR, Responsible Care and REACH have developed in order to improve the situation. Today, environmental issues play a central role in the society, but what are the reasons behind this increased environmental commitment? PURPOSE & The purpose of this thesis paper is to study the driving forces behindDELIMITATIONS: the increased environmental awareness in companies. Is this mainly due to stricter legislations, or do factors like pressure from the general public, the industry or customers play a more vital role? Furthermore, do economic incentives exist, that make it interesting for companies to invest in environmental awareness? Since the chemical industry spans over a wide spectrum in regard to environmental issues, this paper will focus on a specific area of the industry.

Analys och utveckling av boggi till ramstyrd dumper

Volvo Construction Equipment is one of the worlds largest manufacturer of heavymachinery. In Braås, Sweden, they develop and manufacture articulated haulers inseveral sizes. The biggest, the A40, is capable of loading almost 40 metric tonnes.These haulers have a bogie to distribute the forces of the load evenly onto the two axlesand there wheels. The bogie is constructed using a rigid balance beam on each side ofthe frame connecting the axles or an independent solution using hydropneumatics.An analysis has been made in order to establish the forces created during corneringand through the theory, an estimation of the extensive tyre wear and extra fuelconsumption has been made. All due to the effects of the tyres not being inline with thecornering radius.

Vikten av gemensamt avslut vid datorförmedlad kommunikation i en lärandemiljö : En studie om att reducera det sociotekniska glappet vid flexibel undervisning via videokonferens

I rapporten undersöks problemställningen ?Hur kan teorin om Gemensam grund och specifikt ?gemensamt avslut? bidra till en ökad förståelse för betydelsen av social interaktion i flexibel undervisning via datorförmedlad kommunikation?? i en fallstudie med fokus på videokonferenssystem vilka används i lärandemiljöer. Resultaten som framkom tydliggjorde att då ett sociotekniskt glapp uppstår tvingas studenterna att skapa alternativa strategier för att kunna uppnå just det här gemensamma avslutet. Därmed uppvisar också resultaten att drivkraften att uppnå gemensamt avslut inte endast är stark vid kommunikation som sker ansikte mot ansikte utan även vid datorförmedlad kommunikation. Fallstudiens resultat kan därmed ses som ett bidrag till grundforskningen i det att betydelsen av att uppnå gemensamt avslut vid datorförmedlad kommunikation uppvisas, vilket också förstärker betydelsen av Clarks (1996) teori om gemensam grund.
