The bean bruchid, Acanthoscelides obtectus is a major threat to bean production. In Ethiopia, where this study was performed, the damage by bruchids on stored beans has been reported to reach up to 38%. To use the isolates Beauveria bassiana and Metarhizium anisopliae in the management of A. obtectus can be an environmentally safe alternative for controlling the pest. In the present work the aim was to examine if the four chosen fungal isolates, B.

The purpose of the study was to investigate the use and losses of energy in an existing older building. Another purpose was also to look through various options for heating systems with renewable energy in the building. The aim was to reduce the use and losses of energy. The first step was to study the related electricity bills of the building and also perform measurements and calculations of the building envelope and ventilation. The next step was to find out the possible actions for energy saving by performing measurements and calculations.

In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water. In order to further understand if this technology would bring a positive impact in the developing countries, the company contacted the Swedish University of Agriculture for a socio-economic study of the Airwaterwells? potential. The authors elected Cost benefit analysis as the appropriate method for conducting the study and India became the study region because of its many problems with water related issues such as diseases as well as insufficient water supply for households. The regions that this study is based on are Gujarat, Haryana and Uttar Pradesh given their differences in income, health situation and poverty rate.

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.

Uppsatsen beskriver arbetet och undersökning för hur deduplicering i filsystemet ZFS påverkar effektförbrukningen. En större mängd redundant data förekommer i centraliserade lagringssystem som förser virtualiserade servrar med lagringsutrymme. Deduplicering kan för den typen av lagringsmiljö eliminera redundant data och ger en stor besparing av lagringsutrymme. Frågan som undersökningen avsåg att besvara var hur ett lagringssystem påverkas av det extra arbete som det innebär att deduplicera data i realtid.Metoden för att undersöka problemet var att utföra fem experiment med olika typer av scenarion. Varje scenario innebar att filer kopierades till ett lagringssystem med eller utan deduplicering för att senare kunna analysera skillnaden.

Given that the oil prices have risen and the environmental regulations has become more stringent, the interest in operating efficiency has increased. The project has investigated the possibility of producing electricity from waste heat generated in the diesel process. One technique to utilize and convert energy into electricity is the ORC (Organic Rankine Cycle). This process is based on the Rankine process (the steam process), the difference from the traditional Rankine process is that instead of water as a working medium, an organic substance is used. The main component used in the process is a evaporator, a turbine, a condenser and a pump.

This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.

Kärnkraftverk är högteknologiska system med hög komplexitet och utan att hantera den här komplexiteten kan små olyckor få katastrofala följder. Närvaron av komplexitet försämrar förmågan att förstå situationer, minskar kontroll samt ökar risken för incidenter. Stabsarbete inom kärnkraftsdomänen kräver ett agilt beteende för att hantera den höga närvaron av komplexitet. Agilitet är förmågan hos en enhet att framgångsrikt genomföra, hantera och/eller utnyttja förändrade omständigheter. Syftet med arbetet är att utveckla ett mätverktyg för att identifiera indikatorer på agilt beteende i stabsverksamhet inom kärnkraftsdomänen.

Today every organization is committed to some kind of environmental scanning in order to get necessary knowledge of the world around them. The acquisition, organization and storage of information in combination with a strategic use, is today an important factor for a successful organisation in any sector of our society.In this Master thesis I have studied how an organisation such as The Confederation of Swedish Enterprise (Svenskt Näringsliv) handles its information resources. I have also looked at the flow of information within the organization. The Confederation of Swedish Enterprise is Sweden?s largest business federation representing 50 member organizations and 55 000 member companies.

One of the most common ways to produce heat and electricity in Europe today is by the incineration of waste or combustion of coal. These materials can be very sulfurous and during combustion sulfur dioxide is produced. This is an environmental and health related toxic substance which is why power plants have strict regulations on removing it from the flue gas. Sulfur dioxide is removed from the flue gas by adding a limestone reagent. The sulfur dioxide reacts with the limestone and the synthetic product obtained is ?Flue Gas Desulfurization gypsum?.

In contemporary encryption the vast amount of text subject to cracking has brought about the demand for methods distinguish files more likely to be encrypted. The encryption software Truecrypt can encrypt files that are not possible to identify with a file signature. To solve the detection problem, an algorithm sensitive to the absence of structure in the very code of files was developed. The program was written in the programming language EnScript which is built into the forensic software suite EnCase. The essential part of the algorithm therefore deployes the statistic of a chi-square test for deviance from a uniform distribution to distinguish files with contents that appear to be random.

En fallstudie tillämpades för att undersöka de inbyggda apparna, Internet Explorer 10, den nya utforskaren File Explorer och reparationsverktyget ?Återställ datorn utan att ta bort filer? i Windows 8. Analysen visade att apparna E-post, Kontakter och Meddelanden sparade större delar av användarens Facebook-profil lokalt på datorns hårddisk. När bildfiler öppnades upp med appen Foton sparades miniatyrbilder av originalet på hårddisken. När videofiler spelades upp med appen Video sparades filnamnet i filer.

Efficient energy use in the housing sector is crucial for achieving a sustainable society. The expansion of this sector only represents a fraction of the existing houses, hence it?s within the existing houses the potential for energy savings lie. This potential has been analyzed in order to determine if it?s possible to cut the current energy demand in half.

Processing information in complex everyday life recruites different abilities than limited storage capacity. Working memory, the central executive and inhibition are constructs that have been used to describe this ability of adaptation. This paper investigates the connection between working memory capacity and performances in tasks closely associated to real life situations, i. e. verbal fluency tasks.
