Våga ta steget!: En studie om de attraktiva produktkategorierna

This paper studies patterns of consumption within a product category. Using make-up as a base for the study, we applied the Mokken Scale to examine if consumers follow a hierarchical pattern when buying items within the product category. Based on a survey of 250 female respondents, we establish a hierarchic scale for consumption. Assuming generally accepted attributes for determining physical attractiveness, the results of the Mokken Scale study were cross referenced with a survey among 200 male and female respondents. Students were asked to evaluate pictures of a model using different combinations of make-up, i.e.

När förmänniskan blev den moderna människan

The subject of this bachelor-level thesis in archaeology in the transition from archaic sapiens to anatomically modern humans, and what might have caused this transition. A part of the study aims to prove or disprove whether an increased consumption of shellfish might have caused this development. Another part of the essay deals with the connection of said evolution and the suggested emergence of cultural and ritual practices in South Africa circa 100 000 BP and an evaluation of the arguments concerning the aquatic ape hypothesis, and their usefulness for the subject.The result of investigation of the theory about the increased consumption of marine resources as a probable cause of the last biological step of creating our species points to the conclusion that it is a probable explanation. There is even some evidence that there could be a connection between consumption of marine resources and the "Out of Africa 2"-theory. It is harder to find a proven connection between the suggested emergence of cultural and ritual practices, even some evidence seems to strengthen the idea.

OTEC för Tarawa

Ocean Thermal Energy Conversion, OTEC, a technology using the temperature difference between cold deep seawater and warm surface water, can extract the work in the form of electricity. OTEC gives also synergies of drinkable fresh water. The temperature difference has an impact on the efficiency of the technology, which means that the feasibility of OTEC is geographically limited. The project intends to explore the possibility of replacing the atoll Tarawa?s present electricity generation with an OTEC plant and to explore synergies. In the present situation all of Tarawa?s electricity is generated by fossil fuels.

Glava glasbruk : En undersökning av föroreningar i mark- och vatten samt ansvaret för dessa enligt miljöbalken

The Swedish industrial society has left several areas with contaminated soil and water which today is of danger for the environment and human health. One of these areas with contaminated soil and water is the region where the former Glava glassworks operated during 1859 to 1939. The main object in this study has been to study the responsibility for the contaminations according to the Environmental Code. The method used is a qualitative content analysis of relevant literature to answer the following questions:What types of contaminations can be found in the area of Glava glasswork and what health issues can these cause?What kind of activity has been conducted in the area that have caused the contaminations in soil and water?According to law, what are the responsibilities for the contaminations in soil and water at Glava glassworks?The contamination in the region has been confirmed to originate from the glasswork due to the environmental engineering survey made in the area in 2009.

Lersten i skånsk byggnadstradition

The use of earth bricks in Scanian building traditionThe present work is concerned with the manufacturing and use of earth bricks inbuilt heritage in the south Swedish province of Scania. The first part of the studyprovides a thorough description of the traditional use and manufacturing of earthbricks based on relevant literature, archive material as well as interviews withinformants. This forms a basis for the second part of the study in which practicalexperiments on and tests with earth bricks where carried out. This involved themaking of traditional earth bricks of different composition. The new handmadebricks were compared with industrially produced bricks (extrusion bricks) and oldhandmade bricks.

Campus ? en dimmig verklighet : -

Alcohol consumption and student life have been connected through many years. Many people establish their drinking habits during their years as a student and drinking habits among students are therefore an extremely important topic. The aim of this study was to examine the drinking habits of students at Växjö University. The study included 98 respondents who answered a survey concerning sex, age, living status, social relations, social desirability and drinking habits. The result indicated that male students consumed more alcohol than female students.

Metod för inventering av underhållsbehov för skogsdiken

Large areas have been ditched in Sweden during the past 100 years to improve the forest production. Ditching and also maintenance of old ditches are operations having mainly negative effects on water quality, flora and fauna and changing characteristics of soil. The purpose of this study was to suggest a method for inventory of the need for ditching maintenance in old forest ditches that takes biodiversity, water protection and forest production into consideration. Inventory methods from five Swedish and Finnish forest companies, agencies and organisations were compared. Their employees were interviewed about their handling with ditches, forest production and nature conservation.

Energieffektivisering av Åhlénshuset i Umeå : Utredning av åtgärder för ventilation, värme och kyla

Sweden is a country that has made some progress in developing energy efficient solutions. The problem in Sweden is that many houses and apartment buildings are old and have inefficient ventilation- and heating systems. This energy is lost when systems are inefficient, which then results in huge economic costs. Luckily, more and more people are becoming aware of this, which means that Sweden is on track to become even better within energy efficiency.Energy use for the housing- and service sector amounts to 166 TWh of total use at 616 TWh. Without distribution and conversion losses, these figures show that the housing- and service sector accounts for almost 40 % of the country's total energy consumption.

Nautikerns möjlighet att reducera bunkerförbrukningen

The work aims to clarify what nautical officers onboard in today's merchant can do to help reduce bunker consumption during the voyage? The question we have asked ourselves during the autumn term in 2008 much was said about the premium bunker prices, and how the future could affect our daily lives as nautical officer. We felt here that the school had relatively little knowledge of the subject and therefore felt that it would be interesting to identify how it really looks like onboard the ships today. To collect information we contacted 7 Swedish companies that operate with different types of vessels, in order to get a broad picture of the whole industry. For shipping companies we asked questions about how actively they were working on the issue and what methods they used.

Konvertering från direktverkande el i kommersiella lokaler : Ekonomisk och hållbar utveckling

Buildings worldwide account for 40 % of the total energy use. Climate change is of increasing importance, but few are willing to reduce their standard of living or get a higher cost for the change. Energy efficiency of existing buildings gives the greatest benefit economically and environmentally. The real estate company Klövern AB manages 46 properties in Karlstad. Heating is the major cost of the total operating costs of real estate. Rising energy prices increase the need for Klövern AB to improve energy efficiency and to investigate alternative sources of heat.

Älgarås avloppsreningsverk- studie och metodisk felsökning av en biobädds BOD-rening

Wastewater contains biodegradable materials, which are often measured as BOD7.Trickling filters are sometimes used as a purification step for BOD-reduction. Atrickling filter is a tower, which is filled with a carrier material. Microorganisms growon the carrier material in the form of a biofilm. This biofilm consists mostly of bacteriathat purify water from BOD.In Älgarås? wastewater treatment plant the water is purified by a trickling filter.However the treatment plant has difficulties reaching the emission requirements forBOD.

Validering av metoder för analys av Cu, Fe och Na i processvatten med AAS-grafitugn

Södra Cell Mörrum is one of the five paper pulp plants that are included in Södra Cell, and the paper pulp that is produced here is not only sold to Swedish paper mills. Most of the paper pulp is exported to different countries in Europe. In the manufacturing process the plant needs different kind of process water and there are guideline values for how much copper, iron and sodium this water is allowed to contain. Analyzes of this water is in the current situation done with an atomic absorption spectrometric instrument (AAS-instrument) with a flame. Measurements done with flame-AAS of samples that have concentrations near the guideline values for copper, iron and sodium, are not reliable. The reason for not being reliable is that the quantitation limits of these metals are higher than the limit values.

ZigBee-teknikens möjligheter att trådlöst överföra EKG-signaler

In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power.
