Popular science Temporal variation of soil respiration at Skyttorp Soil respiration (Rs) is a major component of carbon fluxes from terrestrial biosphere to the atmosphere with contributing 30-80% of annual total ecosystem respiration in forests. Rs, refers to the production of CO2 from soil by respiration of root and microorganisms, is normally demonstrated by soil CO2 flux in the unit of μmol m
Problem/Background: Sweden was organised against contraceptives through the contraceptive law between 1910 to 1938, causing many women to perform unsafe abortions. Towards the end of the period Sweden became more accepting of contraceptives. Purpose: To further investigate the specific law “lex hinke” and the discourse or discourses that could indicate change towards a more contraceptive friendly
Internal migration has become debatable issue in China, since there are more and more migrant workers after social economic reform. Those migrant workers, attracted by better job opportunities in cities, have made great contribution for urban areas; but at the meantime they are suffering from restrictions caused by household system. In this thesis the main purpose is to figure out the links betwee
This essay provides an analysis of the relation between the value added tax (VAT) and the size of the informal sector in Africa. The proposed hypothesis is that due to incentive mechanisms provided by VAT, tax evasion, and hence the size of the informal sector, should decrease when VAT replaces other standard consumption taxes, primarily the retail sales tax (RST) and the turnover tax (TOT). The
Syfte: Detta arbete har som syfte att undersöka den eventuella förekomsten av skillnader i riskjusterad avkastning mellan aktieportföljer bestående av bolag verksamma inom oljeproduktion respektive servicebolag inom oljesektorn Metod: För att undersöka om skillnader i riskjusterad avkastning föreligger har vi skapat två olika portföljer innehållande femton bolag ur respektive sektor. För dessa por
Wide bandwidth time-of-flight spectrometer (TOFS) developed in the Group of Biophotonics,Lund University, is a unique tool which is capable to deliver continues absorption/scattering spectra of turbid samples in a singularly broad wavelength range from 600nm up to 1400nm. The main focus of this thesis work is to calibrate and optimize the performance of the instrumental setup of this system for bi
Phosphorus-filter with reactive filter material has shown good potential to reduce P in wastewater from single households. In 2006 the Swedish EPA updated the restrictions for wastewater treatment for single households(NFS 2006:7) according to the environmental code. Apart from minimizing nutrient loss the new restrictions also suggests that phosphorus(P) in the filter should be recycled back to a
Today's food production contributes to many different kinds of environmental problems such as greenhouse gas emissions, eutrophication, discharge of toxic substances and deforestation. Because of this, various types of environmental labels have been introduced to assist consumers in choosing products that have a lesser environmental impact than others. Svenskt Sigill and KRAV have developed a
Manganese is a heavy metal that acts an essential micronutrient for plants and animals, as well as it is toxic in great amounts. Mn2+ is the form of manganese that is biologically available for plants and micro organisms living in soil. How much manganese a plant needs and tolerates varies greatly among different species. The amount of available manganese in soil also varies among different soil t
If Europe is to meet its Kyoto commitments and avert further environ- ental damage and climate change, urban car traffic has to decline drastically. Yet, no efforts to master the challenge have succeeded. Planners need new demand side tools to help facilitate more sustaina-ble travel patterns and increase use of public transport. This thesis is a literary contribution to the EU SUNSET and Swedish
Nyckelord: Hållbar utveckling, hållbar mat, ekologisk produktion, jordbruk, LCA, miljö- och klimatsmart mat, Sveriges miljömål Problem: Den globala livsmedelsproduktionen ansvarar för en relativt stor del av världens totala miljöpåverkan. En hållbar utveckling behövs och inte minst en hållbar produktion och konsumtion av mat. Studien tar ett grepp genom att med fokus på hållbar utveckling, tolka bProblem: The environmental impact from food production accounts for a relatively high percentage of the world’s environmental impacts. We need a sustainable development, not least a sustainable production and consumption of food. The study focuses on the concept of sustainable food through a comprehensive approach. Furthermore, the study embraces different impacts food creates on the climate and e
Within the scope of this project, investigations were made into the possibility of replacing Electron Beam Lithography (EBL) with NanoImprint Lithography (NIL) for creating arrays of gold dots on substrates, with the aim of nanowire growth. The attempted nano wires grown were aimed to be of use in the field of biotechnology. The main focus and aim of this project has been to perfect a fabrication
The aim of this thesis is to present experiences and lessons learned from the initial implementation process of the rating system STARS at Washington University in St. Louis: mainly the strengths/opportunities can be used to overcome the weaknesses/threats that the STARS implementation may entail. Strengths and opportunities such as increased student involvement in processes such as assessing sust
A cost-benefit analysis is performed following inevitable renovation requirements for the public outdoor swimming facilities situated in Ljungbyhed and Östra Ljungby. The purpose of the thesis is to evaluate whether or not it is economically acceptable to perform the necessary investments to keep the facilities operating. The benefits are estimated using observed data regarding the number of visi
This sociolinguistic bachelor thesis concerns the attitudes towards youth language and language changes in the Swedish language. A lot of sociolingustic research has been done on the field of both youth language and language changes, but there are no previous Swedish research concerning the same questions as in this study. This is an apparent-time study with a synchronous perspective and only one
This study examines the underlying patterns of savings and investments in China for the period 1978 – 2008. The institutional changes that occurred as a result of the 1978 economic reforms programme brought about profound changes to the characteristics of savings and investments in China. The paper finds that household savings while high, do not explain China’s high savings rate as a whole. High s
