Recent phylogeographic work on Taricha torosa has revealed that the subspecific lineages, T. t. torosa and T. t. sierrae, are distinct evolutionary lineages that form a secondary contact zone in the southern Sierra Nevada of California. I examined the dynamics of this contact zone using two allozyme markers, mitochondrial DNA, morphometrics (head shape), and head color pattern. The subspecific lin

Background Acetabular cementation during total hip arthroplasty is considered difficult mainly due to the appearance and anatomy of the acetabulum. Improved cementation technique has been shown to improve the longevity of acetabular components. Method We designed a ceramic model to investigate the effect of varying the initial cement pressurization and cup introduction times on the depth of cemen

A new sub-micron beamline for high-resolution nuclear microprobe applications has been constructed at the Lund nuclear microprobe facility. The design and construction of the main experimental chamber.. sample viewing system and computer controlled precision sample stage movement is presented in this paper. The chamber is especially designed for using a large area annular HPGe detector. The advant

In this paper we discuss the possibility of a general paradigm for cell-biomaterial and cell-nanoparticle interactions. The basis of the paradigm is that the nature of the biomaterial or nanoparticle surface is not the important parameter, but rather the nature of the outermost layer of adsorbed proteins as well as long-lived misfolded proteins shed from the surfaces. If the adsorbed protein is ir

This thesis investigates the role states play in promoting and directing a country’s development. More specifically, it is examined, which factors determine differences in state performance and why different types of states form. This is done through a comparative case study of Botswana and Zambia, two southern African countries that after a similar start into independence developed very different

In this thesis, a theory testing research of two comparative cases has been conducted. By applying the Rational Choice inspired theory by Adam Przeworski, upon the two cases of the negotiations revolving around the civil war in Bosnia-Herzegovina and the war between Serbia and Kosovo, it has been examined whether the theory can be used to explain the difference in outcome. The essence of the theor

Where debtors seek to open insolvency proceedings in a Member State that have the most favourable insolvency regime it is referred to as "forum shopping". According to Article 3 (1) in conjunction with Article 4 of the European Insolvency Regulation the appropriate jurisdiction and the applicable law are determined by the core element of the Regulation the debtor´s "centre of main i

This paper investigates whether the information from a number of different economic variables have the ability to predict stock returns on the OMXS30. The estimated forecast models are evaluated with a number of standard metrics to find the best performing models. These models are then used in combination with two portfolio strategies and tested over different time periods and forecast horizons, t

Advance pricing arrangement (“APA”) becomes a common tool to attract foreign investors to carry out their business in the Member States’ territory. The advantage of APA which providing legitimate expectations to the taxpayers is one of the reasons of why the companies file an APA request to the tax authorities. However, APAs are not free from issues or problems arose, especially in relation to t

The “Substitution Principle” gives the direction to substitute hazardous substances to less dangerous ones when possible. The idea of substituting substances to less dangerous alternatives is currently of concern and the “Substitution Principle” is one of the tools used to do so. This has come into focus since polluted lakes, air and/or land areas has ended up as consequences of chemical emissions

The aim of this study is to examine the determinants of capital structure via a cross-country comparison between the U.S.A. and Sweden. With the consideration of firm specific factors, the main focus is on researching country effect and macroeconomic impacts on firms’ financing policy. Including both country and macroeconomic factors in the research allows for having a new approach on the topic. T

This study investigated the quality and availability of environmental education (EE) in Dhading Besi, Nepal. Focus was placed on the cultivation of students’ agency and their participation in environmental actions. Interviews were conducted jointly at two local high schools with students and teachers, and with climate science researchers and local environmental NGOs. The study found that current e

This research tries to prescribe Chinese trade impact on Africa by analyzing the underlying link between trade openness and growth. We invoke trade openness theoretical and methodological tools to instrument our explanatory variable and control for causation, allowing us to measure the relationship between geographical component of trade and the level of income. We find no significant relationship

Abstract A radar study was performed to compare flight parameters between sparrowhawks and common buzzards during autumn migration at the Falsterbo peninsula, Sweden. Common buzzards had higher flight altitudes and were more selective for wind, yet their air - and cross-country speeds were lower than those of sparrowhawks. Furthermore, common buzzards had higher glide ratio, but lower airspeed w

The fall of the Berlin Wall in 1990 signified a new era in European history. Most of the former socialist countries started a process of transition from centrally planned to the market economy already in 1990. Many studies have been undertaken with the aim of analyzing the effects of privatization and transition in former Soviet countries, but there is significantly less literature about privatiza

The purpose of this study was to analyze selected passages of the short story The South Wind by the Iraqi writer Abd el-Malik Nuri, which was done in order to find out how the description of characters, setting, and events, are related to class. The main research questions dealt with how the use of word choice and imagery are used in connection to the setting and characterization, but also how the
