Execution time is an important issue in the field of numerical analysis. Simulations are getting more and more complex and the execution times are rapidly increasing. In the scope of this thesis a time integration library is used to solve initial value problems. The aim of the thesis is to implement and investigate two different approaches to decrease the execution time for the library. The main f

During evolution the human brain has increased drastically in size compared to that of other primates. However, little is known about primate brain development as it is difficult to study human and primate brains in the laboratory due to the scarcity of tissues. Yet, it is essential to study primate brains and understand the molecular features leading to the human brain’s unique cognitive function

By the end of the 1960s there was a growing environmental concern all around the globe. As a part of an answer to this challenge the need was recognized for a reorientation of the education processes towards developing knowledge, attitudes and skills for resolving the issues. This was the birth of the concept of Environmental Education (EE). However, this notion is far from being static as it went

Positive aspects of fathers’ involvement in parenting are broadly recognized, but challenges faced by fathers are often neglected and postpartum depression (PPD) is still mainly considered as a problem of mothers. Yet, new evidence suggests a similar prevalence of about 10 % in fathers and mothers. The present study investigated paternal PPD, its character and its links to attachment styles, paren

The use of a label for locally produced products is seen as a good way of promoting these products in Söderslätt and, thereby, promoting regional development. The only common meaning of the concept ?local? is the reference to a geographical area, even though the size of the area differs. Local products are associated with characteristics such as environment, ethics, health, quality and support of

This master thesis presents a qualitative model for performing a due diligence analysis of non- financial risks and their management, the DANFiRM model. The model includes a thinking process and a working procedure for identifying and evaluating the current non-financial risk exposure at the target enterprise and further required measures for altering risk exposure and risk management activities t

Metals play a key role as a cornerstone of our modern society; they are part of the most basic elements of our daily life and have been part of our lifestyles for millennia. Current trends of metal production point out that developing countries in order to attain a developed-countries consumption level will require 3-9 times the present metal stock per capita, yet their mining practices are far fr

Countries around the world are employing renewable energy policies to increase renewable electricity in their electricity mix. Trinidad and Tobago (T&T), located in the Caribbean, has endogenous sources of oil and natural gas and has not yet capitalised on sources of renewable energy. The country‟s electricity is currently dominantly generated from natural gas however the natural gas reserves

Det här examensarbetet ger en översikt över organiskt material (kerogen) i Jordens yngre lagrade berggrund och hur detta material omvandlats till olja och naturgas genom olika geologiska processer. De viktigaste är tryck, temperatur och tid. Med fortskridande sedimentpålagring förs det organiskt rika sedimenten successivt ned på större djup, där de genomgår en så kallad mognadsprocess till följd aThe origin, composition and maturity of kerogen, and its conversion to petroleum is reviewed. Various methods for estimating the maximum temperature to which kerogen and potential source rocks were subjected are also reviewed. Several kerogen maturation parameters can be distinguished and grouped into two categories: chemical paleothermometres and biological paleothermometres. Biological paleother

The aim of the present study was to take a closer look into the evidence for a theory of prehistoric string manufacture, formulated by the British archaeologist Karen Hardy in the article Prehistoric string theory. How twisted fibers helped to shape the world (Hardy, 2008). A problem with the article, with the relevance and validity of the presented evidence as substance for the theory, was the mi

Recent trends of permafrost thawing in the subarctic are expected to cause increased release of dissolved organic carbon (DOC) to inland waters, which might have cascading effects on downstream aquatic ecosystems and release of CO2 to the atmosphere. This study therefore aimed at evaluating the applicability of an empirical band ratio algorithm for estimating chromophoric dissolved organic matter

Public procurement and the purchasing of goods, services and works comprises about 14% of the European gross domestic product (GDP). Procurement initiatives, guidance and tools therefore can have significant influence to leverage demands for more sustainable and circular products and services. This study explores the current circular public procurement (CPP) landscape, looking at barriers and oppo

Uppsatsen är baserad på två hovrättsdomar angående internetavstängningar i Indien med en systematisk innehållsanalys av rättsliga yttranden och en teori om yttrandefrihet i informationssamhället. Syftet med studien är att förstå resonemangen från domarna kring implementeringen av lagarna, både i de två utvalda domsluten och domarnas tolkning av yttrandefriheten och rätten till personlig frihet. De

The thesis explores online knowledge production around a subject that has been considered taboo and inappropriate through history – sexual, reproductive and genital health for people with female genitals. Therefore, it also examines the political potential of coming together to openly discuss such “delicate issues”. The focus of the study is the Swedish Facebook-group “Fittlife – underliv och häls

Som en följd av EU-beslutet om ett nettonollutsläppsmål till 2050 har flera industrier utvecklat färdplaner för hur dessa utsläppsminskningar ska uppnås. Det här examensarbetet undersöker kemiindustrins färdplaner i syfte att bedöma hur de ser på sin roll i att nå EU:s utsläppsmål. Teknikerna och strategierna som används i färdplanerna för att nå utsläppsminskningar varierar stort. Ofta antas att Following the decision set by the EU of a net-zero greenhouse gas emission target for 2050, several industries have made roadmaps for how these reductions will be achieved. This thesis investigates the chemical industry roadmaps in order to assess how they envision their role in reaching the EU target. The technologies and strategies used in the roadmaps to reach the reduction targets vary widely,
