The systems AeAl2-xMgx (Ae = Ca, Sr, Ba) display electron concentration induced Laves phase structural changes. However, the complete sequence MgCu2 → MgNi2 → MgZn 2 with increasing x (decreasing electron count) is only observed for Ae = Ca. Compounds SrAl2-xMgx (0 < x ≤ 2) and BaAl2-xMgx (x = 0.85 and 2.0) were synthesized and structurally characterized by X-ray diffraction experiments. For the S
This paper begins with describing a case study of using the standard Web Map Services (WMS; from Open Geospatial Consortium) for mobile applications. There are two experiences from this case study that are interesting for the generalisation community: the amount of map information on the screen and the map file size. In this paper a usability study of the amount of map information is presented. Th
Pneumococci isolated from the ear exudate in 245 children under 10 years of age afflicted with acute otitis media were typed. Types 3, 6, 14, 18, 19 and 23 were found in 80% of the cases. In the remaining cases, 15 other types were found. Five strains were not typable with the antisera used. Types 14 and 23 were found twice as often in the age group 0-3 years as in the higher age groups, whereas t
Recently, there has been a rise of contributions in innovation and economic geography studies on how firms from specific industries and regional innovation systems (RISs) rely on international networks to innovate. So far, the focus has been on single cases, firms located in well-known RISs and international linkages, without really distinguishing those with geographically close partners from thos
Two dolerite dyke swarms are recognized along and paralleling the Ural Mountains, Russia. The Uralian swarm is 1400-km long (2300-km long if traced from its inferred plume centre). Further north, the Pay-Khoy swarm can be traced through the Pay-Khoy–Novaya Zemlya fold belt for a distance of c. 250 km (800-km long if traced from its inferred plume centre). An Upper Devonian age for volcanism associ
Myriad debates in electoral politics have drawn attention to the importance of and risks to genuine democracy brought about by factors such as campaign spending, incumbency, political party affiliation and political dynasties. However, only a few studies utilize integrative and multivariate approaches to understanding the contribution of these factors, and this is even rarer for studies on the Phi
Airborne wear particles originating from disc brakes are one important contributor to the concentration of airborne particles in urban environments. It is therefore of interest to improve the knowledge of these particles. The purpose of this article is to investigate the concentration and size distribution of the airborne wear particles generated from the contact between a low-metallic pad materia
Focal non-convulsive status epilepticus (fNCSE) is a neurological condition characterized by a prolonged seizure that may lead to the development of epilepsy. Emerging experimental evidence implicates neuronal death, microglial activation and alterations in the excitatory and inhibitory synaptic balance as key features in the pathophysiology following fNCSE. We have previously reported alterations
Little is known about the contribution of the private health sector in managing malaria cases and contributing to malaria prevention and control efforts in Ethiopia. We assessed 102 private health facilities and 92 drug outlets in 20 districts of Oromia Regional State, Ethiopia, for their provision of malaria-specific services. Of the assessed health facilities 86% provided such services. Diagnosi
The COVID-19 pandemic has wreaked havoc in every country in the world, with serious health-related, economic, and social consequences. Since its outbreak in March 2020, many researchers from different fields have joined forces to provide a wide range of solutions, and the support for this work from artificial intelligence (AI) and other emerging concepts linked to intelligent data analysis has bee
Global aging has raised increasing concerns on the health and well-being of older adults. Public transport is a viable option to improve the mobility and quality of life among older adults. However, policies that promote the public transport use among older adults are rare. This study utilizes the eXtreme Gradient Boosting (XGBoost) decision tree to explore the non-linear associations of the built
The COVID-19 pandemic has led to enhanced hygiene procedures and use of personal protective equipment, but also to increased attention to occupational skin disease in healthcare workers. The occurrence of hand and facial skin disease in > 5,000 Swedish healthcare workers was investigated in a questionnaire survey. Levels of skin exposure related to hygiene procedures and personal protective equipm
The three-dimensional structure of a 42-residue fragment containing the N-terminal EGF-like module of blood coagulation factor X was determined by means of 2D NMR spectroscopy and computer simulation. The spectroscopic data consisted of 370 NOE distances and 27 dihedral angle constraints. These were used to generate peptide conformations by molecular dynamics simulation. The simulations used a nov
While general trends in Central European postglacial recolonisation dynamics are relatively well known, we often lack studies on intermediate (meta-population, landscape) scales. Such studies are needed to increase our understanding of, for example, the location of refugia; emergence of endemism, rates and trajectories of postglacial migrations; and anthropogenic landscape changes. Here, we focuse
Background: Studies on sensitization to metals in the general population are scarce. Objectives: To determine the prevalence of sensitization to metals in the general population, and factors associated with nickel sensitization. Methods: In 5 European countries (The Netherlands, Germany, Italy, Portugal and Sweden), a random sample (N =3119) from the general population (aged 18-74years) was patch
Larks constitute an avian family of exceptional cryptic diversity and striking examples of convergent evolution. Therefore, traditional morphology-based taxonomy has recurrently failed to reflect evolutionary relationships. While taxonomy ideally should integrate morphology, vocalizations, behaviour, ecology, and genetics, this can be challenging for groups that span several continents including a
The photocatalytic performance of two-dimensional materials is largely limited by the fast recombination of photogenerated charges. Herein, we design and fabricate a novel g-C3N4/BO0.2N0.8 van der Waals heterostructure to realize oriented charge flow in-plane and separation within the interface. On one hand, a B-C bond forms within the g-C3N4/BO0.2N0.8 interface after the introduction of O atoms.
Differential cross-sections are measured for top-quark pair production in the all-hadronic decay mode, using proton-proton collision events collected by the ATLAS experiment in which all six decay jets are separately resolved. Absolute and normalised single- and double-differential cross-sections are measured at particle and parton level as a function of various kinematic variables. Emphasis is pl
