Energianalys mellan programmen IES (Integrated Environmental Solutions) och Enorm

An increase interest of new methods and tools has begun to grow in the real estate business, this new trend causes an increase in new programs that aim to simplify processes of energy-efficiency and environmental issues.After consulting with Björn Alsmark from Bjerking AB, an architect and engineering company, we made a decision that the Degree Project is going to examine the program IES (Integrated Environmental Solutions) with some integrations from Revit Architecture application.To be able to examine IES, we got access to a completed project from Bjerking. The project is a nursery school in Uppsala. An application has been handed in from Bjerking to make this project to a Green Building-certificated project. According to Bjerking own calculations (with the energy-calculation program Enorm), the consumption of energy of the nursery school is 48 percent lesser than required by BBR.An evaluation of IES and Enorm has been made with an aim to compare these two programs and find out if IES is an appropriate program to replace Enorm. Does Enorm or IES come up to BBR´s recommendations?The Degree Project cover 15 ECT, that required several adjusting and delimitations, and the study sketch ended with a literature study.After finishing the study sketch the modeling of the nursery school began.

Förstudie till våtmark i Rimbo : Design för optimal hydrologi och kväverening

The euthropthication of the Baltic Sea is a threat that is beginning to be taken seriously by the governments concerned. In Sweden, regulations concerning the allowed nitrogen (N) concentration in the effluent water from wastewater treatment plants are being tightened up. The Rimbo wastewater treatment plant has been imposed to reduce the annual mean concentration of total N in the effluent water to levels below 15 mg l-1. A more and more common way to reduce the nitrogen level in wastewater is to let the water pass through a wetland. This study investigates the possibility to build this kind of wetland at the outlet of the Rimbo wastewater treatment plant.A prestudy of the topography, soil characteristics and groundwater flow indicates that the land area in question is well suited for the construction of a wetland.

Kaliumgödsling på torvmark - effekt på tillväxten hos planterade granar (Picea abies)

Peat  lands  are  a  great  potential  resource  for  increased  forest  growth  in  Sweden, there  are  approximately  6.5  million  hectares  of  peat  lands,  whereof  around  70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste  land.  There  are  over  200  000  hectares  of  peat  land  that  is  already  drained and  wooded,  and  that may  be  suitable  for  fertilization.  Forest  production  on  peat soils  usually  requires  drainage  and  fertilization.  Dewatering  requires  ditching  the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The  purpose  of  this  work  was  to examine  the effects  of  potassium  fertilization  on the  growth  of  spruces  that  were  planted  on  drained  peat  land  and  how  different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance  transport  in  the  tree.  Potassium  is  also  important  for  the  carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter  resistance  of  many  species.  Potassium  is  not  found  in  any  organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was  left  without  fertilization.  All  plots  that  were  fertilized  with  potassium  grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality  estimation  of  wetlands  after  ditching  (dikningsbonitering).  The  plot  with most  potassium  produced  after  fertilizationaproximately  in  level  with  theoretical estimations.  Key  words:  Peat  land,  Fertilization,  Ditching,  Growth,  site  quality..

Ingen Lag - Straff? Straffansvar och befogenheter för svensk militär personal i internationella insatser ur ett rättstillämparperspektiv.

INGEN LAG ? STRAFF? ABSTRACTThe thesis deals with a gap in the Swedish legislation concerning the criminal responsibility under which military personnel act in international peace operations. According to international treaties called Status of Forces Agreements, military personnel operating abroad within the territory of other states are exempted from the criminal law of the host states. In return, their home states apply its national criminal law upon the personnel instead. Thus, Swedish criminal law is applied in relation to actions taken by Swedish military forces in international operations.

Produktutveckling av koncept för isbanesystem

Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.

Lesbiska flyktingar i offentliga dokument

The means that the Swedish State has to legitimize and standardize different perspectives of women and their sexuality is significant. Persecution of gender and sexuality is today something that can grant refugee status according to the Swedish Aliens Act. By studying the documents that forestall the amendment of the laws is it possible to unveil the concept and ideas about women sexuality that the state manifests and reproduces through these laws and official documents.The aim of this essay is to look upon the sexual policy as it occurs in official the documents that deal with lesbian refugees. The study cover and maps present research on this group of women and gives an answer to how norms about women sexuality are expressed in these documents.Throughout the survey of the research field not much previous research was found, therefore even research that only partly covers the field is included and reviewed.As method a detailed reading of the official documents and a discourse analysis with it?s emphasize on theoretical themes like gender and sexuality, lesbianism and state feminism, was made.

Revisor idag, redovisningskonsult imorgon : Har revisionen spelat ut sin roll i mindre företag?

In 2010 mandatory audit was revoked for small and medium sized companies in Sweden. At the same time the authorization for accounting consultants was established with the aim of raising the knowledge and status of the profession. Even though The Swedish Companies Registration Office has discovered more errors in the accounting after the mandatory audit was eliminated, it especially concerns those companies who does not have neither an auditor or an accounting consultant. One of the reasons often mentioned to be audited is the auditors role when it comes to lending decisions. Our empirical studie show that the auditors most important function, being unbiased, is not what is of greatest importance for the credit institutions.Instead it was professional skills, and for small and medium enterprises (SME) it was consulting they requested the most.

Metodik för utmattningsberäkning av svets i vibrationsmiljö

In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.

Dimensionering av industrilager för biobränsle :

The aim of this study was to develop a simple model for calculating stock costs for bio fuel at Billerud Karlsborg and subsequently recommending a suitable stock level of bio fuel. The stock components considered in the model are GROT (branches and tops), bark, dry wood chips, raw wood chips from barking and sawdust. The calculations are based on a probability distribution of historical deviations between ordered and delivered volumes. The model presents two different ways to manage the supply in case of irregular deliveries. The first way is to stock enough volume to cover the deviations and the second way is to compensate with a quick purchase from the spot market (at extra high purchase prices).

Kommunfullmäktigeledamöters sociala representation -en fallstudie i tre svenska kommuner av kön, ålder och etnicitet

The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.

Girls just wanna have fun - Tjejers rätt till tjejgrupper

The purpose of this essay is to examine how girls groups, particularly in school, can help girls with feelings of stress and pressure they can experience in their everyday life. We also want to examine how girls groups can be used, and explain why they should be held in school and not only in other organizations. The information we?ve gathered comes from books and websites that cover the subject. In addition to this, we?ve also handed out surveys and implemented interviews with both younger girls with girls groups experience, a teacher and a youth recreation leader. The theoretical aspect of this essay stems from two different theories: Labeling theory and Strain theory.

Är kolrika jordar en källa till fosforläckage? : en sammanställning av data från 130 åkerjordar

Phosphorus (P) is an essential nutrient but a surplus could lead to eutrophication. Furthermore, the minerals used to produce the mineral phosphate is a non renewable resource. There are in other words several reasons to reduce the leakage of P and the agriculture is one important area to attend. The aim of this work has been to investigate if carbon-rich arable soils content contain more P than arable soils with low carbon content. Moreover it has been calculated if the carbon-rich soils could pose a risk of P leakage by comparing their delivery of P with the plant uptake. The work has consisted of compiling the results from former gathered and analysed soil samples of 130 Swedish arable soils. The fractions of P considered are water soluble P (Pw), ammonium lactate-extractable P (P-AL), hydrochloric acid-soluble P (P-HCl), organic ammonium lactate-extractable P (Porg-AL) and inorganic ammonium lactate-extractable P (Porg-HCl).

Prim, Stadsförnyelse i Barcelona

This final project discusses renewal and upgrading of the area of Prim. It is discussed how this industrial area can be an attractive neighborhood with a varied range of services and commercial trade. Prim is located 2km north-east of the center of Barcelona. The area boarders to a deep railway valley that historically has separated Prim from its neighboring districts. At present there is almost no housing, services or commercial trade within the area and the industry is discontinued or the existing industrial buildings are derelict. There is also a lack of green recreational areas.
