Growing GaAs nanowires with well-defined crystal structures is a challenging task, but may be required for the fabrication of future devices. In terms of crystal phase selection, the connection between theory and experiment is limited, leaving experimentalists with a trial and error approach to achieve the desired crystal structures. In this work, we present a modeling approach designed to provide

The study and development of a decision support system for doctors and students is presented, aiming to ease the diagnosis of the cervix cancer through an automated smart system: using a web application, a medical expert can upload colposcopic images feeding an expert system that carries out a deep analysis by a processing system on images uploaded by doctors; results coming out of the processing

In situ X-ray absorption spectroscopy (XAS) investigations have been performed to provide insights into the reaction mechanism of a palladium(ii) catalyzed undirected C-H acetoxylation reaction in the presence of an oxidant. A Pd(ii) N-heterocyclic carbene complex π-stacked onto reduced graphene oxide (rGO) was used as the catalyst. The Pd speciation during the catalytic process was examined by XA

The ability of chyle chylomicrons to bind prothrombin has been studied. Rat chyle chylomicrons were incubated with human 125I-prothrombin and binding was examined by separating the chylomicrons from free 125-I-prothrombin by density-gradient ultracentrifugation, and by gel filtration on Sepharose CL-2B. A significant binding of prothrombin to chyle chylomicrons occurred. The complex formation was

The influence of solvents on enzymatic activity and stability was investigated. As a model reaction the α-chymotrypsin-catalyzed esterification of N-acetyl-l-phenylalanine with ethanol was used. The enzyme was adsorbed on porous glass beads and used in various solvents. Small amounts of water were added to increase the enzymatic activity. These enzyme preparations obeyed. Michaelis-Menten kinetics

This thesis describes an improvement of the glyoxylate ene reaction by using siamyl glyoxaylate and a development of the novel rearrangement of allyl benzyl ethers. The glyoxylate ene reaction was used as a key reaction in a 8-step synthesis of a Taxol A-ring building block. During the work with the ene reaction it was found that the ene component underwent a rearrangement to give arylbutanals in

Risk and vulnerability assessments (RVA) are vital components of the work conducted by public agencies at different levels, as part of the processes for governing and managing risks in the society. In Sweden, public agencies at all levels are required by legislation to perform risk and vulnerability assessments within their respective area of responsibility. The present paper presents a study of h

BACKGROUND: High reproducibility of test measurements is often considered an indication of high reliability of test results. The aim of the current study was to analyse the role of the traditional perimetric reliability indices, False Negative and False Positive responses, and Fixation Losses, as indicators of test reliability in comparison with threshold reproducibility in patients with suspect o

Increasing trends of natural organic matter (NOM) in surface water in Nordic countries may cause future problems for drinking water producers. Emerging membrane technology, such as ultrafiltration (UF) and nanofiltration (NF), has the potential to produce safe drinking water of good quality from sources with high organic concentrations. In the present pilot study, surface water from three sources

We propose a distributed learning algorithm for fair scheduling in common-pool games. Common-pool games are strategic-form games where multiple agents compete over utilizing a limited common resource. A characteristic example is the medium access control problem in wireless communications, where multiple users need to decide how to share a single communication channel so that there are no collisio

Stricter Swedish building regulations require a moisture-safety design process to be carried out before houses are built. In order to predict moisture-critical conditions, a properly verified, user-friendly and reliable calculation tool that could be used in this design phase, is required.This paper initially presents a blind method that could be used in order to verify heat and moisture calculati

Description of the paper – e.g. topic, research question, objective, purpose, value, conceptual or theoretical framework, state of the art: Adult learning is a subject of ever growing interest, as the population of persons 65 and older grows in industrialised countries. By 2010 the number of retired persons in the European Union will be almost twice as large as in 1995 (Ilmarinen & Costa, 2000

A model for foot skin temperature prediction was evaluated on the basis of an experiment on subjects at -10.7 °C (light seated manual work) with winter boots. Insulation of the footwear was measured on a thermal foot model. The predicted temperature stayed higher for the whole exposure period and the difference between the predicted and the measured foot skin temperatures grew proportionally with

Prediction of the spread of combustion gases from a fire is a major area of interest when analyzing buildings from a safety point of view. Hence programs with this aim are continuously being evaluated for the estimation of their validity. The purpose of this report was to produce and compare complementary results for an up to date version of the program Fire Dynamics Simulator (FDS) to what was pr

This study examines whether the new EU enlargement strategy has brought expected results and led to the changes that go beyond adoption of formal rules and institutions in Montenegro. It establishes whether improvement in the sphere of judicial independence occurred since the introduction of the new EU approach to enlargement, in the next most likely candidate, by analysing the impact of each comp

How to increase trade flows in today's globalized world is a relevant topic and the incentives to do so are exemplified by the WTO Trade Facilitation Agreement that came into force in 2017. Inefficient trade procedures have proven to aggravate and decrease trade. Inefficient trade procedures could be obtaining, preparing and submitting documents about the traded good to authorities, as well as

It is not uncommon that states repress and oppress its citizens by exerting violence upon them. Sometimes this violence leads to cases where states abuse their power. This abuse can lead to terrible consequences which several historical and contemporary cases shows. When analyzing state violence, it ought to be put in the context of violence from non-state actors, which often eclipse the violence

This paper explores discourses about European colonialism and particularly Sweden's colonial legacy in Swedish upper secondary school history textbooks. All three textbooks are currently in use and are based on the latest school curricula from 2011. The theoretical framework used to analyze the textbooks consists of post-colonial feminist theories combined with a post structuralist perspective

Ni-Ti systemet har en stor mängd tillämpningar, inom områden så spridda som biomedicin och robotteknik. Detta beror till stor del på den intermetalliska föreningen NiTi, vilken är en minnesmetall. Utöver denna egenskap är den intermetalliska föreningen dessutom biokompatibel, har bra mekaniska egenskaper och god resistans mot korrosion. Studier på NiTi har visat att temperaturerna kopplade till deThe Ni-Ti system has a broad range of applications, in areas as diverse as biomedicine and robotics. This is in large due to the NiTi intermetallic compound, which exhibits the shape memory effect. In addition to this property, the intermetallic compound is also biocompatible, has good mechanical properties and good corrosion resistance. Studies on NiTi has shown that the temperatures at which the
