Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala
The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.

The three standpoints within the security study that will be used are military security, environmental security and energy security.
Work-Life Balance : En kvantitativ studie av könsskillnader bland civilekonomstudenter
Work-Life Balance (WLB) is defined as the ability to manage both work-life and non-work life successfully. WLB can be evaluated by examining individual?s experience of Work-Family Conflict (WFC) and Family-Work Conflict (FWC), both of which can be assessed by a questionnaire developed by Netemeyer, Boles and McMurrian (1996). The aim of this study was to explore if responses to the questionnaire, the amount of time spent on studies, household chores and sick leave, were gender related or not, among civil-accountants students. The survey included 138 respondents (74 woman and 64 men).
Utvärdering av åtgärdskartor för bostadsrättsföreningar : ett verktyg för val energieffektiviseringsåtgärder
The municipality in Uppsala has set up goals for the future work concerning climate-and energy issues. As one way to achieve these goals the municipality started aproject called Uppsala climate protocol. During one of the project meetings anabatement map was presented. The map showed what savings in carbon dioxide andmarginal costs for different actions can be made. Statistics show that 40 % of thepopulation in Uppsala lives in a condominium.
Energieffektiv torkning av kläder : en studie av torktumlare med varm- respektive kallvattenanslutning
Tumble dryers and drying cabinets have to a large extent replaced the traditional way of drying clothes outdoors. They are faster, more convenient, require less space and can be operated regardless of weather conditions. This replacement has significantly increased residential energy consumption, due to the fact that tumbles dryers consume large amounts of electrical energy. In the USA 9 % of the households electric energy is consumed when drying clothes. Over 4 million tumble dryers are sold in Europe each year and 20 % of the residential electricity consumption in Sweden is used drying and washing clothes.
Skolrelaterad stress hos kvinnliga gymnasieelever : En jämförelse mellan yrkesförberedande och teoretiskt program
AbstractLoeva, J (2013). Schoolrelated stress in female students ? a comparison between vocational and theoretical program. The Academy for health and working life, University of Gavle.Purpose: To investigate and compare perceived stress and recovery among Swedish femalestudents (high school, third degree) in a vocational program versus a theoretical program.Method: A cross-sectional study was conducted on forty female students (vocationalprogram, n=20; theoretical, n=20) to give a cross section of the population in question. Datawas collected by questionnaries, which included questions on perceived stress and energylevels, demand, control and social support at school.
Effektivisering av energianvändningen i en förskola
This rapport contains an examination of the energy consumption of a kindergarten, which areas that have the largest impact on the energy consumption and what can be done to reduce those areas in ways that are relatively easy and profitable. It is also analyzed if it is possible to reduce the energy consumption from today?s consumption to a consumption that fulfils the demands placed on low energy houses by FEBY.The focus has been on reducing the energy consumption of the areas ventilation, heating system and hot water system, since those seemed to be the easiest ones to affect and since the building is quite recently built.There are different kinds of ventilation systems, at the moment the building have a CAV-system, which means that the ventilation is too high during large parts of the day. There are different ways to manage the ventilation system, for example presence detection, humidity sensors, CO2 sensors, temperature sensors and season adjustment. Many of those are in the end dependent on CO2 sensors to guarantee a good indoor climate, therefore the focus have been placed on this system.
Coreträning: finns det ett samband mellan bålmuskulatur och balans?
Coreträning består av statiska och dynamiska övningar för bålmuskulaturen. Syftet med studien var att ta reda på om det fanns ett samband mellan bålmuskulatur och balans samt om en träningsperiod med Coreträning kunde påverka balansen. En litteraturstudie har gjorts där åtta artiklar granskades. Dessutom bestod studien av en empirisk del där nio försökspersoner fick sin statiska och dynamiska balans testad före och efter en 4-veckors period med Coreträning. Som mätmetod användes unilateral stance test med NeuroCom® Balance Master® 8.03 och dynamic balance test med Biodex® Balance System.
Flexibel för ökad tillgänglighet : Sjuk- och undersköterskors perspektiv på work-life balance
Work-life balance är ett ämne som det har forskats mycket om de senaste åren. Denna undersökning har applicerat de befintliga teorier som finns inom work-life balance och relaterat dessa till yrkesgruppen sjuk- och undersköterskor. Denna yrkesgrupp är intressant då det för närvarande råder brist på sjuk- och undersköterskor på dagens svenska arbetsmarknad. På grund av denna brist ställs denna yrkesgrupp på höga krav både vad gäller flexibilitet och tillgänglighet. Denna undersökning har redogjort för de samlade teorier som finns inom work-life balance, flexibilitet och tillgänglighet.
Sensory studies of an energy dense drink for elderly people
The average length of life is increasing in the western world, hence the older population is growing. A common health problem among the elderly is malnutrition.
Malnutrition causes decreased body strength and is associated with an amplified risk of infections, depression, fractures and increased mortality. The health
care system is therefore faced with the challenge to prevent malnutrition among the growing population of elderly. This could be done by providing nutritious
foods developed to meet the specific needs of elderly. The overall objective of this project was to test a healthy energy dense drink based on oats targeted for the elderly
consumers as a strategy to prevent malnutrition among elderly.
Karriärist javisst! : En kvalitativ studie om fäders upplevelser kring vård av barn
Following is a study of fathers 'experiences of balance between work and home life. The method the researchers used was based on qualitative interviews aimed at describing father?s own experiences and values, which affects them. The researchers chose to specifically study situations where the fathers were faced with situations where their children needed to be cared for in the home because of a cold or similar illness since this is a situation that directly affects the time that was meant for work, but now risk being moved to areas of life that the researchers define as home life. This is to see whether the respondents felt that this situation affected the balance between work- and home life.
Rening av lakvatten vid deponin Degermyran i Skellefteå kommun : Utvärdering av nuvarande reningseffekt och simulering av mängden bildat lakvatten under 2000-talets klimatförändringar
At Degermyran landfill, situated in the municipal Skellefteå, a leachate treatment system was installed in 2005. One of the aims of this study was to investigate how well the treatment system works by using data from chemical measurements made on the leachate before and after treatment. Further this study had the purpose of investigating how the predicted climate changes of the 21st century will affect the amount of leachate generated at Degermyran by using a modified version of Thornthwaites water balance model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come.
Utsikten : Hållbara uppvärmningsalternativ för vandrarhemmet på Finnhamn
Finnhamn is a small group of islands in the Stockholm archipelago. At Stora Jolpan, the biggest island, there is a hostel. The main building was built in 1915 and is called Utsikten. The purpose of this project is to on behalf of the Archipelago Foundation (Skärgårdsstiftelsen) find alternative systems that can replace the existing heating system of Utsikten (an oil-fired boiler and electricity heaters) to a system with renewable energy. The alternative system that this project focuses on is a system of solar collectors combined with a wood chip boiler.
AVREGLERINGEN AV APOTEKSMONOPOLET. En studie av de enskilda aktörernas förutsättningar att verka på den svenska apoteksmarknaden
With the globalization, companies in the West chose to shift production to developing countries to cut down costs. This had a major impact when child labor and very poor working conditions in these factories were discovered and led many companies to take responsibility for their suppliers and the employees by adopting voluntary so-called Codes of Conduct.There is a subtle balance to enforce improvement of working conditions for employees at suppliers´ factories and to keep costs down. On the one hand, companies would like to conduct extensive audits at their suppliers to ensure code of conduct compliance and thus protect their legitimacy. On the other hand, audits are expensive so companies would like to minimize audits to keep costs down. Companies thus have to strike a delicate balance in relation to how many and what suppliers they choose to audit.
Uppvärmningssystem : Ekonomi, miljö och drift
This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating.
