The purpose of this study is to examine the optimal hedge ratio for the currency exposure of foreign investments. The optimal hedge ratio is determined after evaluating our portfolios from the three perspectives; ex-ante, ex-post and profit/loss. The ex-ante perspective is examined by the usage of historical simulation to calculate VaR on 11 portfolio pairs. Each pair consists of a portfolio with
This thesis sets out to examine which tax consequences might arise when moving a closely held company abroad, according to Internal Law, European Community Law (EC Law) and Double Taxation Treaties. To be able to illustrate the tax consequences I have chosen to look at a specific case where a shareholder undertakes a sale of shares of his Swedish company to a foreign company also owned by him. The
A combination of acoustic trapping and impedance spectroscopy for micrometer-sized objects is here presented for the first time. Acoustic trapping has proven to be a well-functioning method for non-contact immobilization and positioning of particles or cells in microfluidic channels. The combination with impedance spectroscopy allows for simultaneous electrical measurements on the trapped objects.
Swedish law only permits termination due to breach of contract when the committed breach is fundamental. To assess the fundamentality of a breach of contract is no easy mission. The main purpose of this study is to clarify the legal meaning of the concept of fundamental breach as a prerequisite in Swedish law for terminating a commercial contract. This study thoroughly focuses on the assessments o
Sodium ion batteries have been considered as promising alternatives to lithium ion batteries for large-scale renewable energy and smart grids applications due to their low cost and rich resources. However, critical drawbacks such as low energy density and poor stability are hindering their development and application. In this work, a stable symmetric sodium ion cell using sodium vanadium pyrophosp
Background and aims: Animal studies have suggested that high salt intake might increase the risk of metabolic dysfunction-associated steatotic liver disease (MASLD), but results from populations are mixed, in part due to inadequate salt intake measurement. Salty taste preference is the primary factor leading to salt choice and can reflect habitual salt intake. However, no study has investigated
Objective: Failure to rescue (FTR), defined as mortality due to failure in responding to in-hospital complications, is an important quality indicator. This study aimed to assess incidence and predictors for FTR among centers performing fenestrated-branched endovascular aortic repair (FB-EVAR) of thoracoabdominal aortic aneurysms (TAAA). Methods: Consecutive patients treated by FB-EVAR for TAAAs be
Introduction: Haemophilia A care has changed with the introduction of emicizumab. Experience on the youngest children is still scarce and clinical practice varies between haemophilia treatment centres. Aim: We aimed to assess the current clinical practice on emicizumab prophylaxis within PedNet, a collaborative research platform for paediatricians treating children with haemophilia. Methods: An el
Waterborne diseases lead to over 6 billion diarrheal episodes per year, with most of the burden on children in low-income countries. We employ hydrological engineering principles to construct a novel measure of stagnant water, crucial to the spread of these diseases. Using a difference-in-differences approach, we estimate the causal effect of stagnant water on the health and cognitive skills of Ta
Background Cutaneous leishmaniasis (CL) is frequent in travellers and can involve oro-nasal mucosae. Clinical presentation impacts therapeutic management. Methodology Demographic and clinical data from 459 travellers infected in 47 different countries were collected by members of the European LeishMan consortium. The infecting Leishmania species was identified in 198 patients. Principal findings C
The continuous fabrication via membrane emulsification of stable microcapsules using renewable, biodegradable biopolymer wall materials keratin and chitosan is reported here for the first time. Microcapsule formation was based on opposite charge interactions between keratin and chitosan, which formed polyelectrolyte complexes when solutions were mixed at pH 5.5. Interfacial complexation was induce
Macroalgae are important habitats which can be found almost all over the world. An alteration has been observed from perennial species to annual filamentous algae during the last decades. This change has affected the abundance, diversity and composition of the invertebrate fauna living in these habitats. This study observes how the increasing amounts of epiphytic, filamentous algae growing on the
Tidigare forskning på diverse olika sporter har visat att mått på visuell kontroll, exempelvis tidig och lång sista blickfixering på målobjektet (Quiet Eye Onset och Quiet Eye Duration) innan en kritisk fas av kinetisk aktivitet hänger ihop med positivt utfall på precisionsuppgifter. Mått på kinetisk aktivitet har också studerats och visat att exempelvis maxhastighet i rörelsen är lägre på träffarPrevious research on various sports has shown that aspects of visual control, namely an earlier onset and longer duration of the final fixation on the target (Quiet Eye Onset and Quiet Eye Duration) before a critical movement is associated with successful outcome on a precision task. Measurements on kinetic activity have also been studied and shown that hits are associated with lower max velocity
Background and objectives Baonaise is a novel plant-based savoury sauce. Baonaise sauce base (BSB) is produced from baobab fruit pulp. Creaming and phase separation were observed in Baonasie from previous studies at the company. In this study, concentration, temperature and type of oil, speed and time of mixing were studied to investigate the factors influencing the physical stability of baobab p

Denna uppsats handlade om antisocialt beteende kopplat till (upplevd) självförmåga (selfefficacy) och självkänsla (self-esteem). Syftet var att undersöka ifall det finns en korrelation mellan grad av antisocialt beteende och grad av självförmåga och självkänsla. Hypotesen är att ju högre grad av antisocialt beteende desto högre grad av självförmåga och lägre grad av självkänsla. Metoden som använd
Two reactors, initially operated at 14 and 23 +/- 1 degrees C (RA and RB, respectively), were inoculated with a bacterial consortium enriched and acclimatized to the respective temperatures over 4 months. The biofilms, formed in the reactors, were studied using scanning electron microscopy, cultivation of the biofilm microflora, and physiological analysis of the isolates. Two bacteria able to mine
