Vakuumisolering ? Ekonomiskt försvarbart för småhus?
The number of people in the world and the urbanization increases. This leads to a bigger need of space for the built environment, space that soon doesn?t exist. A large portion of humanity?s energy disposal is used for heating of buildings.
Analys av internt produktflöde för ökad kapacitet
This master thesis was carried out at ELFA, one of the largest catalogue distributors of electronics in northern Europe. ELFA offers a wide selection of products such as measuring instruments, fuses and screwdrivers. The master thesis handles the possibilities of an increase in the internal flow of products. The background to this problem is ELFA?s acquisition of two new companies, which brought the product range in the warehouse from 55 000 to 80 000 products.
Effects of Driver, Vehicle, and Environment Characteristics on Collision Warning System Design
The purpose of the present study was to examine effects of driver, vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ?risk? and ?safety margin? respectively. Rear-end collision had a stronger focus in the present study.
Geografiska informationssystem för studier av polyaromatiska kolväten (PAH) : undersökning av djupvariation i BO01-området, Västra hamnen, Malmö, samt utveckling av en matematisk formel för beräkning av PAH-koncentrationer från ett kontinuerligt utsläpp
At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofcarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.
Allanblackia stuhlmannii ? a tree under current domestication: what are the soil requirements?
Allanblackia is a genus of trees that grows in the rainforests of West, Central and Eastern Africa. Its big fruits contain seeds very rich in oil which has been used by
local communities for cooking and making soaps. The native stands are threatened by overexploitation and the demand for the oil is much greater than the supply.
Domestication programs, aiming at introducing the trees to small holder agroforestry systems, have been started for some of the species. The main aim of this study was to investigate the soil requirements of Allanblackia
stuhlmannii in terms of chemical and physical parameters, as revealed by the soil conditions in native stands. Another aim was to see if these varied along an altitudinal transect.
En studie av sedimenttransport, död ved och kantzoner längs två vattendrag i Kilsbergen - från skog till slätt :
Headwater streams are affected by anthropogenic impacts at multiple scales.
One aspect of human impact is sediment transport associated to the
abundance of stream structures as large woody debris and the composition
of the riparian zone from forest to agricultural landscapes.
Riparian buffer zones and stream structures like dead wood are considered
as generally important structures for protection against an increasing
amount of sediment particles in the water. Hence, in this study these
structures were quantified in thirty different stream segments on land and in
the water.
To measure the transport of sediment Whitlock-Vibert boxes were used in
three different types of landscapes; forest, transition and fields. The boxes
were left in the stream segments for three months, the taken up and dried
and weighed. The results showed that the transition-land in Frösvidalsån
had the highest sediment transport. The second highest transport of
sediment was in Blackstaån at the fields.
Ett gårdsbesök : ger besöket någon kunskap om mjölkproduktion?
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations Higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Rabies awareness, incidence and vaccination coverage in Lilongwe, Malawi
Rabies kills about 55 000 people every year and more than 90% of infected humans are considered getting the disease from dog-bites. To control the disease and eventually eliminate human rabies, the most efficient and economic method is to keep the dog population vaccinated. The objective of this thesis was to evaluate the situation of canine rabies in two urban areas in Lilongwe, Malawi, where canine rabies is enzootic. In each area 200 household-interviews were conducted in September and October 2013. Focal points were awareness of the disease, human incidence as well as vaccination coverage in the dog population.
Normativa värden för läppkraft hos barn mellan fem och tio år : Relaterat till bilabial stavelseproduktion
Lip force has been found to affect the ability to achieve satisfying speech production and swallowing. A normative value for lip force in adults has been measured to 15 Newton (N). Corresponding value for children measured with Lip Force Meter 100 (LF100) does not exist. In the current study lip force was measured in children between the ages of five and ten years. The aim of the study was to obtain normative values for children with typical development in separate age groups.
Evaluation and Comparison of Ecological Models Simulating Nitrogen Processes in Treatment Wetlands,Implemented in Modelica
Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).
Impact of hygiene training on dairy cows in northeast India : en hygientränings påverkan på mjölkkor i nordöstra Indien
Mastitis in dairy cows is an emerging and challenging disease in the tropics, including India. Nation-wide reports suggest that the incidence of clinical mastitis varies from 3.94% to 23.25%, and for subclinical mastitis from 15.78% to 81.60%. In Assam, a northeastern province of India, dairy is an essential part of the mixed farming system that exists in the state, but the milk yield is far below domestic standards. In 2009-2010, International Livestock Research Institute (ILRI) and local associates started to develop a training program for local farmers in Assam, in order to enhance the informal bovine dairy sector in and around Guwahati, India. The project continued until mid-2013.

Comparison of bird communities in stands of introduced lodgepole pine and native Scots pine in Sweden
The introduced lodgepole pine (Pinus contorta) occupies more than 650 000 hectares in Sweden. There are some differences between lodgepole pine and Scots pine (Pinus sylvestris) forests which could affect bird assemblages, for example differences in canopy density and ground vegetation. Birds were surveyed in 14 localities in northern Sweden, each characterized by one middle-aged stand of lodgepole pine next to a stand of Scots pine. The two paired stands in each locality were planted by the forestry company SCA at the same time and in similar environment to evaluate the potential of lodgepole pine in Sweden. In those 14 localities, one to three point count stations were established in both the lodgepole pine and the Scots pine stand, depending on the size of the area.
Vad påverkar en aktieanalystillförlitlighet? : En kvantitativ studie om relationen mellan tillförlitligheteni en aktieanalys och dess innehåll.
A debate in finance is whether a random investment gives the same return as carefully choose and valuing an amount of shares to invest in. Stock valuating Stock valuation is often done by fundamental valuation models, based on the company's underlying character, which tries to put a correct price on the stock. Today there are several different valuation models that can be used for this purpose. Since valuation models are only mathematical, equity research is underpinned by more subjective assessments about the company and its future.The purpose with this thesis is to describe which valuation models that are used by professional stock analysts, but also to see if the reliability on the equity research is affected by the used model to valuing the company. Furthermore, we want to see if the job that?s been done to understand the company, measured by the equity research quality, impact the reliability on the equity research.In this thesis, we have, to achieve our purpose, conducted a quantitative content analysis of 164 equity research done by professional analysts at firms listed on the Stockholm Stock Exchange. With basis in previous research, we have developed a method for determining the valuation model that is used in the equity research, the reliability on the equity research and a framework for assessing the quality of the equity research.In the theoretical framework the valuation models involved in our study are described, previous research on the reliability on the equity research and their practical use.
Utbildningens betydelse för våld i nära relationer. En litteraturbaserad studie om associationen mellan kvinnors utbildningsnivå och våld i nära relationer i låg- och medelinkomstländer.
Introduction: Intimate partner violence (IPV) is a great public health issue that can cause serious physical, psychological and psychosomatic injuries to the woman. Education is one out of many important protective factors against IPV. Aim: This study aimed to investigate the association between women?s educational level and IPV in low- and middle-income countries, the interaction between the education of the woman and the man and IPV, how education on different levels (individual-, family- and community-level) influences IPV and how gender is connected to education and IPV. Method: A literature-based study with 12 selected scientific articles as the foundation for the analysis was performed.
