Pedagogiska miljöer : Barns och pedagogers uppfattningar om den pedagogiska miljöns erbjudande utifrån ett genusperspektiv

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.

Utbildning i våld i nära relationer. En kvantitativ studie om betydelsen av personalutbildning för att främja det preventiva arbetet.

Background: Intimate partner violence (IPV) is a large public health problem that foremost affects both women and children, nationally and globally. Several accessible reports about IPV and education for staff that in their occupation can meet battered people shows the importance of increased education for several occupational groups to decrease the large number of unrecorded cases.Purpose: The study explored how six occupational groups, in the municipality of Kungälv, related to IPV in their professions, were influenced by whether they had education in IPV or not.Method: We chose a quantitative approach, a cross sectional study. A questionnaire was constructed and handed out to 156 participations. The occupational groups were a section in a hospital, the police, the home care services, an elementary school, a pre-school and the public dental care. The answer frequency was 86 %.

Utvärdering av koldioxidmätaren Vaisala GMP343 samt sambandet mellan grundvattennivå och koldioxidavgång från torvjordar

The research group Soil and Water Management at the department of Soil and Environment at theSwedish University of Agricultural Sciences in Uppsala are studying greenhouse gas emissions fromcultivated peat soils. To measure carbon dioxide emissions from peat soils in the field the researchgroup are now using two portable carbon dioxide meters (Vaisala GMP343). For practical reasons,they plan to acquire a new type of automated field meter. The aim of this study is to evaluate thepresent meters to see how environmental conditions and instrument settings affect the results,which is meant to facilitate the introduction of the new field meter when the meters needs to becompared. As a part of the study the relationship between groundwater level and carbon dioxideemissions from peat soils will be investigated.The evaluation of the two carbon dioxide meters was made by connecting them to one single airtightsystem, with the aim of creating identical measurement environments.

Tillväxtreaktion hos skärmträd i högskärm av gran i Medelpad :

Different methods for shelterwood cutting have been used in differ-ent parts of Europe since the middle ages. The use of shelter wood cutting in Norway spruce (Picea abies (L.) Karst.) forests in Sweden met a revival in the early 1990s as an alternative for the dominating clear-cutting system when silvicultural costs increased dramatically for the latter. Shelterwood cutting systems involve some possible problems but also a lot of positive effects. Among the problems are increased risk of wind throw and damage of the remaining shelter trees caused by the cutting operation. Positive effects are for example a valuable growth in the remaining trees and increased biological di-versity. This study is based on a total of 79 trees from 4 different treatments in a spruce shelterwood, cut in 1994, in the middle of Sweden (62,4º N).

Tillväxt och potentiell sågtimmerkvalitet i gallringsmogna jämförelseplanteringar med Pinus contorta och P. sylvestris :

The Swedish Cellulosa Companiy, SCA, has today 280 000 ha planted with lodgepole pine (Pinus contorta var. latifolia) (?C?) which is equivalent to 14 % of its total forest area. Exotic lodgepole pine has in previous experimental stands shown a superior growth than the native Scots pine (Pinus sylvestris L.) (?S?).But also the comparison could be questioned because stand histories were was unknown and also differences in age between C and S existed.

Deep Green i oceana strömmar - en konceptstudie

With growing economies and better living standards in many parts of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer.The company Minesto has developed a technology that is called Deep Green. It is designed to gain electricity from tidal currents. Deep Green works in a similar way as a kite that is attached to the seafloor with a moving wire. It contains of a wing that moves due to the water current.

Rituellt, traditionellt eller funktionellt : en osteologisk analys och jämförelse av två förromerska gravfält från Skogome i Bohuslän och Smörkullen i Östergötland

This paper concerns a comparative analysis between two pre-Roman burial ground and the cremated individuals buried there, Skogome cemetery in Bohuslän and Smörkullen cemetery in Östergötland. The comparative analysis consists of several parts that concern both cemeteries inner and outer burial customs, and the osteological analysis of a total of 18 cremated invidvidulas. By studying the different parts separately, it has been possible to identify similarities and differences between the two contemporary cemeteries. There are great similarities between the cemeteries, differences were mainly observed in the osteological material relating to the amount of bone in each burial. The smaller amounts of bone in the graves of Skogome also holds a higher degree of fragmentation, but can not be explained by a higher combustion rate than the skeletal material from Smörkullen.

Konvertering från direktverkande el i kommersiella lokaler : Ekonomisk och hållbar utveckling

Buildings worldwide account for 40 % of the total energy use. Climate change is of increasing importance, but few are willing to reduce their standard of living or get a higher cost for the change. Energy efficiency of existing buildings gives the greatest benefit economically and environmentally. The real estate company Klövern AB manages 46 properties in Karlstad. Heating is the major cost of the total operating costs of real estate. Rising energy prices increase the need for Klövern AB to improve energy efficiency and to investigate alternative sources of heat.

Finansiella instrument för svenska lantbruksföretag : riskhantering och finansiella instrument för lantbruksföretag i Sverige

The survey describes a number of risks that Swedish farming companies are exposed to. The risk areas covered by the survey are currency risks, price risks and financial risks. The survey further describes why these risks have a great impact on the future development of the farming companies. The survey highlights the interrelation between the risks and the measures which can be used to minimize the risks, so-called financial instruments. The aim of the survey is to put focus on above mentioned risks and describe how these risks can be reduced to prevent the Swedish farming industry from stagnating in the future. The survey is a secondary survey whereby existing knowledge about risks and risk management is applied to farming companies. The written information on price risks and hedging is primarily derived from foreign sources.

Inventering av bergborrade brunnar för dricksvatten i område med risk för salt grundvatten : en utredning av grundvattensituationen i Vreta-Ytternäs i Uppsala kommun

The city of Uppsala and its surroundings are a very expansive area. A prerequisite for a sustainable development of the area is well-functioning supply of drinking water. In Uppsala municipality, the Uppsala esker and Vattholma esker are the groundwater storages for drinking water. Besides the eskers, other sources of qualitative groundwater in the Uppsala municipality are relatively poor and more than half of the area consists of ground conditions with a risk of saline groundwater. The neighbourhood of Vreta-Ytternäs is situated 10 km south of Uppsala, in the area with risk of saline groundwater but outside the municipal water supply.

Landskapskaraktärsanalys som verktyg för hållbar byutveckling - exemplet Flädie

There are numerous questions to be asked when your task is to plan a small community?s future development. Is it possible to suggest something new and modern? What considerations should be taken concerning the existing situation? What is an appropriate size for the new development? Where is it possible to build and what is the most appropriate method to use?In this master´s thesis I have tried to develop and describe a working-process where I execute a complete landscape character analysis for the whole community in question to get the answers to where and how it would be most appropriate to develop a village like Flädie without destroying its current character.Flädie is a typical small village in the countryside of Skåne, Sweden. It is strongly effected by the expansive and urban region it?s located in but is still rural in character.

Punktmolnshantering i anläggningsprojekt : Utvärdering av programvaror för framtagande av markmodell

An increased number of participants in the construction industry is asking for accompanying terrain models to the project in order to get a better understanding of the field. When the desire to create buildings that fit together nicely with the surrounding area is increasing, it becomes more and more important to have a broad base of knowledge about the ground on which the building is to be erected. Terrain models are also very useful in the planning of logistics, documentation for landscape architecture projects, and billings for mass calculations.Surveys for creating terrain models can be performed with laser scanning. The advantage of laser scanning is the time-effective surveying, the detailed information as well as the ability of application in complex environments resulting in a cost-efficient project. With this in mind our thesis was defined in collaboration with the company Bjerking AB in Uppsala in order to investigate if there were any softwares suitable for terrain modeling.
