In this work the intermetallic systems formed by transition-metals from group 5 to 9 with Ga, In and Zn have been experimentally and theoretically studied in detail. Syntheses, compositional analyses, X-ray and neutron diffraction (single crystal as well as powder) and measurements of physical properties, e.g. magnetic susceptibility and resistivity has been made for all compounds. Electronic-stru

In this dissertation, we discuss how buyers practice purchasing strategies in an asymmetric power situation favoring suppliers, and how their purchasing strategies practiced impact their purchasing power and buyer-supplier relationships. Organizations enter exchange relationships to access required resources not produced internally, and are exposed to uncertainty from not being able to fully contr

This study documents the advancement of laying dates in three species of tits (Paridae) in southernmost Sweden during recent decades, and the absence of a similar response in the pied flycatcher Ficedula hypoleuca. It is based on several different nestbox studies; the oldest one starting in 1969. During 1969 to 2012, mean spring temperatures in the study area increased by between 0.06 and 0.08 °C This study documents the advancement of laying dates in three species of tits (Paridae) in southernmost Sweden during recent decades, and the absence of a similar response in the pied flycatcher Ficedula hypoleuca.

Many studies have over the years utilized gravity models derived from trade theories to investigate how various factors affect trade in agricultural goods. Although technological improvements could be considered in such models, few studies have considered this topic in depth, leaving a void to fill. To partly fill this void, this study has chosen the silk sector to analyze the impact of technologi

In the recent years, cryptocurrencies have gained popularity and have experienced high price volatility. This essay pretends to examine how the multivariate GARCH models predict the volatility of these digital currencies and what implications exist if we consider the correlations among them to forecast their volatility. Using a bivariate Diagonal VECH and bivariate Diagonal BEKK this thesis checks

This paper examines if competition between internet service providers using city networks leads to lower prices. The research tests the theory of the circular city that in which the price depends on the marginal cost as well as the number of competitors in the market. Based on this theory the cost of a 100 Mbits connection should move towards marginal cost if there are more internet service provid

This thesis examines customer satisfaction within IKEA's support services in Sweden and Great Britain by analyzing customer feedback data. It explores the intersection of anthropology and computational social science, contributing to the growing field of computational anthropology. The study identifies recurring themes in customer comments by employing a mixed-methods approach that combines co

Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related mortality and can occur with any type of transfusion. TRALI is thought to be primarily mediated by donor antibodies activating recipient neutrophils resulting in pulmonary endothelial damage. Nonetheless, details regarding the interactions between donor antibodies and recipient factors are unknown. A murine a
