Biomass losses during short-term storage of bark and recovered wood
Storage of biomass is associated with problems like heat development, biomasslosses, and reduction of the fuel quality. Certain processes such as biological- andchemical degradation are responsible for these storage problems. This master?sthesis was carried out at Vattenfall Research and Development AB and is alignedtowards quantifying the biomass losses from Short-term storage (1-2 months) ofbark and recovered wood. The biomass was stored in outdoor piles during differentseasons, campaign 1 (summer) and campaign 2 (autumn).
Sex jourföräldrars upplevelser av sitt arbete - samspelet med socialförvaltningen, det placerade barnet/ungdomen samt de biologiska föräldrarna
Short-term-fostercare has a huge burden of work, hence they get harder and harder cases since placements in institutions decreases and short-term-forstercare increases. We wanted to study short-term-fosterparents experiences of their work, since they makes an important effort. The aim of the study was to describe the teamwork with them and the groups: the social care, the children/youth and the biological patents, from a short-term-fosterparent perspective. We´ve also been interviewing two fostercare-secretaries, hence we wanted to get an insight in the organization of short-term-fostercare. The study is a qualitative attempt and we´ve done six interviews with short-term-parents.
Kapitalstruktur i svenska små och medelstora företag
The purpose of this study is to investigate the determinants of capital structure in Swedish small and medium sized firms. The study includes 24.859 Swedish firms which are further analyzed with regards to their financial characteristics. These characteristics consist of short term debt, long term debt and total leverage. The study compares the relationship between these characteristics and six independent variables.The result shows that profitability is the greatest determinant for capital structure in Swedish small and medium sized firms with regards to total leverage. When profitability increases the total leverage of the firm decreases.
Kortsiktighet i näringslivet : En studie om förhållandet mellan VD, styrelsen, ersättning och avkastning
This study test the short-termism of companies listed on the market OMX Stockholm 30. We will use a deductive point of view where the purpose of this study is to investigate whether corporate short-term returns can be explained by the independent variables related to corporate governance and compensation practices. This is to investigate whether there is an intentional action on raising the short-term return in order to achieve a higher CEO compensation. In the study, theories dealing with corporate governance and agency theory have resulted in two hypotheses. Basic Hypothesis H1 is: if short-termism of Swedish industry due to the company's short-term returns can be explained by the independent variables related to the company's management and compensation. This hypothesis could not be verified through the quantitative study. Alternative Hypothesis H2 is: the compensation of a CEO can be explained by the independent variables related to company performance and size.

Lagring av kyla med horisontella markvärmeväxlare för kylning av koncepthus i Mellanöstern
Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.
Potatislagring :
The aim with the thesis is to get deeper knowledge in one of the subjects botany, livestock technology or economy. I have chosen to get deeper knowledge in how to store potatoes. How are you going to act to keep the quality on the potato during the storage, with a minimum of weight lost? My aim with this thesis is to get a view over how the potato act in storage space. The storage environment is very important in the storage space.
Inventering av värmelager för kraftvärmesystem
When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.
The Consumer as Barrier vs. The Consumer as Partner
First objective: To bring forward managers? perceptions of the underserved consumers in emerging markets. Second objective: To reveal what implications managers? perceptions of underserved consumers in emerging markets provide for branding in these markets. Our study indicates that managers? perceptions are still lacking consumer insights within five elements (value, loyalty, purchasing power, consumers and consumption).
Framtidens energilagring : en studie av befintliga samt potentiella metoder fo?r lagring av fo?rnybar el pa? ett ha?llbart sa?tt
In today?s society there is an increasing demand for renewable energy sources such as sun and wind power. These sources are intermittent, and energy storage is therefore needed to ensure a constant power supply. This report compares pumped hydro energy storage (PHES), compressed air energy storage (CAES), flywheels, batteries, super magnetic energy storage (SMES) and hydrogen energy storage.The opportunities for further development are limited for PHES and CAES in comparison with the other technologies. Lithium-ion batteries and hydrogen energy storage are considered to have the most potential in the future.
Seriell återgivning av två-röstslistor: ord organiseras inte efter röst
AbstractTitle: Serial recall of two-voice lists: Words are not perceptually organized by voice.The present study examined how voice affects the perceptual grouping of words in short-term memory that are auditory presented. Three different voice-lists were used: single-voice, alternating-voice and split-voice. In single-voice lists all words were presented in the same voice. In alternating-voice lists words were presented alternately in a male and a female voice. Finally, in split-voice lists words were presented grouped four and four in a male and a female voice.
Korttidsboendets mål - Chefers och personals syn på målen för verksamheten
The aim of this thesis is to see if there are differences in how managers and other staff looks at goals for short-term accommodation. The results show that there is a difference in views on the goals. This is manifested, among other things, in the form of managers have their focus concentrated on the financial framework for the business. Other staff have their focus directed at targets that are more about the work of the resident. The theory that the survey is based on is The sense of coherence and its three pillars: comprehensibility, manageability and meaningfulness..
Korttidssjukfrånvaron Vård och Omsorg Öster : vad kan den bero på och hur skulle den kunna minskas
The health care sector Öster has the highest average absence due to short-time sickness in Örebro. It is the short-term absence that has the highest costs for the organisation, not just in money, but also in quality disturbances and administrative work. Health care sector Öster is divided into four areas with a manager for each. We have chosen to conduct our research within the special housings in area one and four, since these two had the lowest and highest short-term absences.The purpose with the research is to examine short-term absences among the health care personnel in the health care sector Öster, see what the absences depend on, and what can be done to solve the issue. We will compare the absences in the area with the highest respectively lowest short-term absences in order to see if there are any prominent differences between the two.
Faktorer som påverkar sockerförlusten vid lagring av sockerbetor : inverkan av lagringstemperatur, lagringstid och vattentillgång
This thesis is a part of the project "Sustainable harvesting and storage of sugar beets, more sugar to practice". The work has included a large part of practical experimental work with weight measurement, graduation and storage planning. The aim of the project is to be able to see whether the cultivars react differently in different storage conditions. The project has included storage under controlled conditions to give as accurate results as possible. To be able to mimic the farmers own preconditions the samples was harvested with a conventional Holmer.This project has two parts, one concerning the nature, time and temperature on storage where a number of different cultivars where investigated during three different recording times, two different temperatures and controlled in a controlled environment.
Flygbesiktning av Luftledningar : Modellering av samband mellan besiktningsanmärkningar och systemtillförlitlighet
This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.
