Utvärdering av AOT för ett pilotskaligt, recikulerat akvakultursystem för fiskodling

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

Energianalys av Svensk Växtkrafts biogasanläggning i Västerås

Svensk Växtkraft is the owner of the biogas plant in Västerås. The company is planning to increase their treatment capacity at their biogas plant. In connection to this work it is also possible to make some energy saving changes to the biogas plant. The objective of this study was therefore to make an electricity and heat survey of the biogas plant, a detailed study of the heat consumption in the sanitation step and also a comparison of energy consumption with the present sanitation method and an alternative strategy where the waste is treated in 55 °C during 10 hours (the current method is heating to 70 °C during 1 hour). The energy survey was conducted in close collaboration with staff at the biogas plant. The current during normal operation was measured, power was calculated and multiplied by the time of usage to obtain the energy consumed.

Carbon Critical Masterplanning tool : klimatpåverkan från samhällsplaneringsprojekt

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area. The results show that use of locally installed renewable energy sources can reduce the total climate impact when life cycle perspective is applied.

Energy analysis of a fruit drying plant in Adeiso, Ghana

The purpose of the project has been to work out recommendations that reduce the energy-related costs and environmental impact of HPW Fresh & Dry Ltd., a fruit drying factory in Ghana. The factory produces electricity with diesel and biogas but also purchases electricity from the national electricity company. Heat for the drying process is produced from biogas, kerosene and solar panels. In the project the energy system was analyzed by measuring production and consumption of heat and electricity. The project results show that the factory can become self-sufficient on heat if the available energy is used more efficient. The production units for both electricity and heat have low efficiencies.

L?ggning av ett kils?gat br?dgolv

This bachelor thesis contains the findings of an investigation into the laying of wedge sawn wood flooring. The advantage of wedge sawn wood flooring is the usage of more material from each board reducing waste. The boards follow the natural profile of the tree where the root part of the board is wider, and the top part is narrower. The technique involves placing boards side by side with adjacent boards in opposite directions. The thick base of one board is neighbored by the narrow top of another, this creates a pattern of wedges in alternating directions, known as a ?root and top? system. Existing literature into this type of flooring is sparce.

Strängluftning av vallfoder : Inverkan på ensilagets torkningförlopp, spill och smörsyratillväxt

When harvesting ley you hope to get a fast drying and a faster harvest. If there is a system with round bales, you need to have a dry matter close to 45 %. To make this as fast as possible, there is made a machine which pick up the grass with an pick-up. It turn the grass over and put it behind the machine (figure 2 and 4). There are few tests to prove the efficiency of this machine.

Underkambriska böljeslagsmärkens bildningsmiljö : Ett försök att fastställa fossila ripplars avsättningsmiljö med hjälp av recenta sandbottnar

ABSTRACTThe fauna of the Lower Cambrian is far from fully understood, as is the environment of that epoch. Some of the most crucial moments in the history of evolution takes place during this epoch; the Cambrian explosion and the appearance of ecosystems as we know them. That makes it an important period to investigate. Doing so, the Lower Cambrian offers a lot of problems, one of which is that body fossils are seldom preserved. That has often left us with trace fossils to create an image of the Lower Cambrian life, but also some bedrock features such as ripple marks.The main purpose of this work has been to investigate the possibilities of relating the wave lengths and forms of recent wave-generated ripples to fossil ones, and also to evaluate the methods for that kind of comparison.

Bäst före 2014 : En studie om matsvinn i livsmedelsbutiker

SyfteVårt syfte är att ge en djupare förståelse för det matsvinn som uppstår i livsmedelsbutiker genom att analysera och utreda servicelandskapets, personalens och kundens påverkan på matsvinn.

Insamlingen av material har skett genom primära och sekundära källor där det empiriska materialet skett genom semistrukturerade intervjuer.SlutsatserI vår arbetsprocess har vi kunnat urskilja att servicelandskapet, personalen och kunden är de faktorer som påverkar matsvinnet inom dagligvaruhandeln.

Hinderbanan - en studie om jämställdhetsarbete och kvinnors förutsättningar inom professionella tjänsteföretag

Although women express a desire to be managers and although they constitute the majority of Sweden's newly graduated academics, they are still heavily underrepresented on senior management level in the Swedish private sector, where men hold as much as 95 % of the top positions. Considering the massive waste of resources that this implies, this thesis sets out to investigate the underlying reasons for the skewed gender distribution on senior management level in two Swedish professional services companies - an industry where the described problem has been palpable. Additionally, the thesis explores the effects of actively working for increased gender equality. With a basis in gender and organization theory, a broad theoretical framework has been compiled and applied to a qualitative case study design. The thesis reveals seven distinct impediments, which together create a parable of an obstacles course, that prevent women from advancing the corporate ladder in the same manner as their male colleagues.

Stadsmöbler för ungdomar :

The title Urban furniture for young people reveals that this paper handles two central phenomenon in landscape architecture; the form and content of the urban spaces, respectively the users and their need for an appropriate outdoor environment in the city. In this paper youth is referred to as 15-18 year olds and the paper is based on theories of their physical use of the city?s outdoor environment. Urban furniture refers to equipment and components in the public room which becomes furniture when people takes them in to claim and gives them a meaning and a function that is useful for the moment. The starting point is that the users, in this case youths, defi nes urban furniture as something signifi cantly more than traditional park furniture, bicycle racks and waste baskets. This paper aims to investigate how the city?s furniture can be developed to meet the youths need to see each other, move and make their marks in the public room. The theories about how youths uses the city are presented in the Theory chapter.

Svensk tjänstehundsavel : en återblick och nutidsbeskrivning samt förslag inför framtiden

In 1936 a governmental breeding project was started with aim on military use. The police later came to use dogs from this project as well. In order to utilize dogs that could fit for other purposes training and education of dogs for search of different substances and of guide dogs for blind persons was performed. A political decision to privatize the whole dog programme was taken in 1992. During most part of the time one had serious economical issues since too few of the dogs that were bred could be considered to fulfil the basic demands for service. To satisfy the need of service dogs private bred dogs were bought as well.

Reducering av ledtid genom en värdeflödesanalys En fallstudie på Lammhults Möbel AB

The purpose of this study is to increase the understanding of activities, flows and waste in a company's production process. By performing a value stream analysis, non-value adding activities are identified in a production process and then the suggested improvements that can reduce lead times will be stated. The value-stream mapping identifies the flow of information and the flow of material in a production process and this provides the basis for the identification of non-value adding activities.We conducted the study at Lammhults Möbel AB in Lammhult Sweden, where the production flow of Spira-21 has been investigated. This to identify any non-value adding activities that affect the flow negative and consumes time and money in a non-value adding way.A reasonable approach for the project was taken by studying the methodologies and theories. We conducted interviews and site surveys at Lammhults Möbel AB where the flow of information and material in the production process were investigated.
