Female growth, number of eggs and egg growth of Daphnia pulex were studied at four temperatures, 12, 16, 18 and 20°C. I hypothesized that female growth and number of eggs would be lower and the size of the eggs larger in the presence of a predator (kairomones) than in its absence. This effect was expected to be more evident at lower temperatures. I could not find any effect of kairomones on female growth, number of eggs or egg size, although there was a weak tendency for an effect on number of eggs. There was, however, an effect of temperature, regardless of predator treatment (i.

Lower energy use in buildings is a result of increasingly stringent energy requirements across Europe. When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain their economic viability the district heating companies? majorchallenge is to implement new solutions that minimize heat loss.

This paper aims to determine what is decisive for localisation of production units when a company engages in offshoring. By performing a case study on Electrolux and comparing the results with theoretical literature we discuss the implications for manufacturing companies in general. To facilitate a structured analysis we have developed a model dividing the localisation decision into five perspectives and four geographical levels. We have found that the determinants of localisation vary depending on the geographical level of the decision process. Since all geographical levels are interconnected, the analysis needed for a decision on all levels simultaneously is very comprehensive.

Allanblackia is a genus of trees that grows in the rainforests of West, Central and Eastern Africa. Its big fruits contain seeds very rich in oil which has been used by local communities for cooking and making soaps. The native stands are threatened by overexploitation and the demand for the oil is much greater than the supply. Domestication programs, aiming at introducing the trees to small holder agroforestry systems, have been started for some of the species. The main aim of this study was to investigate the soil requirements of Allanblackia stuhlmannii in terms of chemical and physical parameters, as revealed by the soil conditions in native stands. Another aim was to see if these varied along an altitudinal transect.

Purpose: To examine the hearing environment for tattoo artists regarding occupational noiseand to see whether tattoo artists are exposed to hazardous noise according to Swedish WorkEnvironment Authority regulations. Method: Using a dosimeter we measured a total ofseven sessions of approximately one hour on seven different subjects, located on five studiosin Gothenburg. As a complement we did also hand out surveys based on twelve questions toexamine habits, experienced sound environment and to see if there were any hearing relatedpatterns. Results:. Sound level measurements showed that the lower exposure action valueLpAeq,8h 80 dB(A) in one case was reached if applied to the average working time of sixhours.

The examination has been performed at Bjerking AB, which is an architectural and engineering company. Bjerking AB has the ambition to be a member of Green Building.The Green Building program developed in year 2005 by The European Commission, the program is an environmental system with the aim to improving energy efficiency within the sectors of non-residential buildings. The minimum requirements to participate the program are following: in new-built buildings the calculated energy consumption must be 25 % lower than the requirements in the BBR (Building regulations) and in refurbishment the reduction must be 25 % lower than before the optimization.The aim of this study has been to examine and review the company Bjerking AB's energy efficiency work in the project of building the school/kindergarten S:ta Maria Alsike, where the goal is to get this building Green Building classed. A description of requirements to become a member of the Green Building has also accomplished in the thesis.The methods performed in this study are literature review, searches on the Internet, studies on the project database for facts/values, calculation of energy consumption and interviews of members of the Green Building. The following issues have been dealt with in the report;-          Did the building in the project manage the requirement to achieve an   energy consumption that is 25% lower than the requirements in BBR?-          What technical measures/system was selected in the building?-          What kind of cooperation was the project based on?-          What is required for consultancy companies and real estate owners to become members of the Green Building?The study of the project and calculation of estimated energy consumption in the building, give the result 47 kWh/m2, year.

At present, the Swedish pig industry is in transition. Prices have been low, but feed prices have increased. Therefore, many pig producers have stopped their production. Producers that lack an integrated production may contract piglet?s producers, or may use the mediation services that slaughterhouses provide.

Polydaktyli är en medfödd missbildning där en individ får en eller flera falanger mer än vad som är normalt hos arten. Defekten uppkommer under den embryonala utvecklingen och är sporadiskt förekommande hos häst. Hos människa tillhör den däremot en av de vanligaste hand- och fot- relaterade missbildningarna. Idag är kunskapen begränsad rörande den genetiska bakgrunden till polydaktyli hos häst. Forskningen om de genetiska faktorer som orsakar polydaktyli hos andra djurslag som t.ex.

Trade is important for every country in the world. Commodities are transported between rich and poor countries everyday. Some of the trading partners are EU and Ethiopia, this because of less expensive commodities from EU than they are in Ethiopia. The most important agricultural commodity is wheat. Ethiopia is a poor country, whose inhabitants mostly are living on agriculture.

Most scientists believe that in the good times the peasant had the opportunity to follow fashion. Virestad parish does not follow fashion. My purpose is to try to understand something of the mechanism that made Virestad do so: that I will do by analyzing the results in relation to the concept of status. My main source is estate inventories. Here I examine the status markers and differences in what they invested in clothes and jewelry in relation to the estate's proceeds.The lower the balance, the more percentage they need to put on clothes.

This paper aims to describe the variation and develop a method to control the production for the product Metropol Kaktus from the snuff developer Fiedler & Lundgren. We are going to use the requirements from the product specifications as limits of the expected quality when we present methods to control the process. One method attempts to control during the process and the other attempts to maximize the number of products with strived quality before the process starts. Metropol Kaktus is a product produced with high quality, the mean weight is 20,023 gram and this is very close to the weight, 20 gram, which is reported in the product specifications. The variation in weight variable is less than what is reported in the specifications and the minimum weight is over the limit set by Livsmedelsverket.

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
