The responses to step and pulse transients with reactants have been simulated for conventional step-transient conditions at atmospheric pressure and pulsing under vacuum using a temporal analysis of products (TAP) reactor, respectively. Propene oxidation over an oxide catalyst with the participation of lattice oxygen was chosen as a model reaction. The mechanism comprises adsorption of the reactan

Using two epochs of HST/WFPC2 images of the metal-rich globular clusterNGC 6528 we derive the proper motions of the stars and use them toseparate the stars belonging to NGC 6528 from those of the Galacticbulge. The stellar sequences in the resulting colour-magnitude diagramfor the cluster are significantly better determined than in previouslypublished data. From comparison of the colour-magnitude

Background: Several studies have found correlations between diabetes and an increased prevalence of periodontitis. Objective: To analyse, in a group of subjects with type 2 diabetes (T2D), (i) the association between medical characteristics and severe periodontal disease and (ii) dental care habits and knowledge of oral health. Methods: One hundred and ninety-one subjects with T2D were examined. B

The determination of elemental abundances plays an important role inunderstanding the atmospheric processes that lead to anomalies inspectra of chemically peculiar stars. Ongoing study of the HgMn star χ Lupi has defined much of the elemental abundance distribution but progress is dependent upon the availability and accuracy of the atomic data. Here we present experimentally determined wavelengths

Inversion recovery (T-1) and microwave power saturation studies have been performed, between 4 and 25 K, on the EPR signal from the stable tyrosyl radical, Y-D(.), in photosystem II core complex preparations from higher plants. Measurements are reported from the dark stable S-1 and first turnover S-2 states of the photosystem catalytic Mn cluster and in two cryoprotectant regimes; sucrose and ethy

This paper describes a pre-screening procedure that was carried out with a number of candidate Human-Machine-Interaction solutions in three different modes (visual, auditory and haptic) for the concepts of “safe speed and safe distance” (referred to as SASPENCE) of an Advanced Driver Assistance System (termed as ADAS). This procedure was performed simultaneously in two European countries, Sweden a

This article presents a mechanical cutting force model for multi-tooth cutting processes, where initial position errors in radial and axial direction, eccentricity and edge wear are taken into account. The cutting forces are presented for each individual cutting edge, and in a system of coordinates where one axis is parallel to the cutting speed vector at any instant. The process parameter cutting

Antibody inhibition and alpha6beta1 ligand binding experiments indicate that the egg integrin alpha6beta1 functions as a receptor for sperm during gamete fusion; yet, eggs null for the alpha6 integrin exhibit normal fertilization. Alternative integrins may be involved in sperm-egg binding and fusion and could compensate for the absence of alpha6beta1. Various beta1 integrins and alphav integrins a

Suitable conditions for separating cells using a chromatographic procedure were evaluated in parallel chromatography on minicolumns. A 96-hole minicolumn plate filled with cryogel monoliths (18.8 mm x 7.1 mm O) with immobilized concanavalin A was used. Chromatographic columns (113 mm x 7.1 mm O) were used for chromatographic resolution of a mixture of Saccharomyces cerevisiae and Escherichia coli

Background and aim Scandinavian Quality Register for Thyroid and Parathyroid Surgery is an on-line web-based database with the aim to improve the quality of thyroid and parathyroid surgery. Preliminary data from surgery for primary hyperparathyroidism are reported here. Materials and methods Fifteen departments registered 806 operations, with 639 women (79.7%) and 167 men. The median age of the pa

In a changing world order, emerging middle powers from the global South may seek new positions in international societies. Using the United Nations as an international society, this thesis aims to investigate what roles the emerging middle powers, Brazil and South Africa, enact in pursuing permanent seats at the Security Council. This research conducts a qualitative text analysis using official da

Motivation: Large-scale phylogenetic analyses rely on orthology inference to curate sets of sequences related by speciation rather than gene duplication. Graph-based ‘orthology’ inference approaches cluster sequences together based on an all-versus-all BLAST, followed by filtering by hit fraction, Markov clustering, or both, but the output of such approaches often contains paralogous sequences. Tr

The student group is an emerging target with high potential for both the service industry and municipalities. However, previous studies scrutinizing this segment have been limited despite its significance. The aim of this study is to provide a deeper understanding of how domestic and international students perceive Helsingborg city and to offer insight into the key factors influencing students’ pe

The museum world is in a time of great change, many of the changes focus on the accessibility of museums. In Sweden these changes are becoming more apparent as the new museum law that has been passed advocates for equal museum experience for all visitors whether they have any for of impairment or not. To encourage this change a few older law and regulations that Swedish museums are also subject to

The symbolic elite discourse on the safety and viability of using the insecticide DDT for combating malaria in Africa is marked by extreme dissonance. While some positions within the debate on using DDT for malaria prevention are quite nuanced, others are more extreme if not one-dimensional. The ones who tend to hold more nuanced or centrist positions on using DDT for controlling malaria are often

Multi and many core platforms are increasingly employed today to cope with the demands of modern multimedia, networking and other similar streaming applications. Selecting the best architecture for a set of such applications is complex, and without coding for each specific system, the choice is made based on designer experience. In this paper we use CAL, a dataflow language for specifying streamin

In light of the growing “coherence” between humanitarianism and political actions in today’s world, does aid remain conducive to socio-economic improvement, or does it inhibit the ushering of much needed change? In the context of this study, the besieged population of Gaza organized large weekly demonstrations known as the Great Return March (2018-2020) to demand their basic political, economic an
