A palynologial study of the Ordovician-Silurian boundary (Katian–Rhuddanian) succession in the Röstånga-1 drillcore, southern Sweden, has been performed. The lithology is dominated by mudstone and graptolitic shale, with subordinate limestone, formed in the deeper marine halo of southern Baltica. The palynological assemblages are dominated by marine microfossils, mainly chitinozoans and acritarchs

We present a method to fabricate nanometer scale gaps within InAs nanowires by selectively etching InAs/InP heterostructure nanowires. We used vapor-liquid-solid grown InAs nanowires with embedded InP segments of 10-60 nm length and developed an etching recipe to selectively remove the InP segment. A photo-assisted wet etching process in a mixture of acetic acid and hydrobromic acid gave high sele

This article analyses and discusses standardisation in human service organisations and its implications for professionals and for professionalism in social work. The theoretical framework derives from neo-institutional theory and theories regarding professionalism. By highlighting the role of professionals within a field influenced by organisational demands and market endeavour, this article contr

Various differential cross-sections are measured in top-quark pair (t (t) over bar) events produced in proton-proton collisions at a centre-of-mass energy of root s = 7 TeV at the LHC with the ATLAS detector. These differential cross-sections are presented in a data set corresponding to an integrated luminosity of 4.6 fb(-1). The differential cross-sections are presented in terms of kinematic vari

To elucidate the molecular requirements for cancer cell internalization of the extracellular cysteine protease inhibitor cystatin C, 12 variants of the protein were produced and used for uptake experiments in MCF-7 cells. Variants with alterations in the cysteine cathepsin binding region ((Δ1-10)-, K5A-, R8G-, (R8G,L9G,V10G)-, (R8G,L9G,V10G, W106G)-, and W106G-cystatin C) were internalized to a ve

The evolution of surfaces exposed to an aggressive environment and mechanical load is studied. This is a process of stress corrosion that leads to pitting, crack initiation and growing cracks. In conventional fracture analyses a known or a postulated crack is required. A serious complication is that a large part of the lifetime of a crack or a surface flaw is spent during the initiation of the cra

Copper, zinc superoxide dismutase 1 (SOD1) is a ubiquitous homodimeric enzyme, whose misfolding and aggregation play a potentially key role in the neurodegenerative disease amyotrophic lateral sclerosis (ALS). SOD1 aggregation is thought to be preceded by dimer dissociation and metal loss, but the mechanisms by which the metal-free monomer aggregates remain incompletely understood. Here we use imp

Purpose - The purpose of this paper is to find out the applicability of the many-body dissipative particle dynamics (MDPD) method for various real fluids by specifically focusing on the effects of the MDPD parameters on the MDPD fluid properties. Design/methodology/approach - In this study, the MDPD method based on van der Waals (vdw) equation of state is employed. The simulations are conducted by

The present paper investigates and discusses the ability of the Hartmann test with a 4-aperture differential image motion monitor (DIMM) to measure the atmospheric primary aberrations which, in turn, can be used for the calculation of the atmospheric coherence time. Through performing numerical simulations, we show that the 4-aperture DIMM is able to measure the defocus and astigmatism terms corre

Previous studies have identified a close relationship between the monospecific Masonhalea richardsonii and Tuckermannopsis inermis. However, formal taxonomic changes were postponed until existing sequence data could be confirmed. Here we validate these data and discuss the transfer of T. inermis to Masonhalea (made by Lumbsch et al. in Thell & Moberg 2011), consider the morphological, anatomic

A major goal in evolutionary biology is to determine how phenotypic variation arises and is maintained in natural populations. Recent studies examining the morphological, physiological and behavioural differences among discrete colour morphotypes (morphs) have revealed several mechanisms that maintain discrete variation within populations, including frequency-dependence, density-dependence and cor

Different methods of preparing lipases for use in organic media are critically reviewed. Solid lipase preparations can be made by typical immobilisation methods such as adsorption, entrapment, covalent coupling or cross-linking. Immobilisation is especially attractive for lipases because, in addition to the normal benefits of enzyme immobilisation, it can also lead to a considerable increase in ca

We have synthesized and investigated the anisotropic growth of interesting silver nanorice. Its growth is kinetically controlled at 100 degrees C, and both oriented attachment and Ostwald ripening are involved, with the former growth mode dominating the anisotropic growth of the nanorice along the < 111 > direction. This one-directional growth is initiated by an indispensable seed-selection proces

The core of evidence-based practice (EBP) as advocated for within the practice arms of the health and social sciences is to promote the routine incorporation of the best available research evidence into practice efforts. This requires discipline-specific education that is not only grounded in professional practice but also prepares would-be scientists in the application of the sophisticated techni

The oomycete Phytophthora infestans is the causal agent of late blight in potato and tomato. Since the underlying processes that govern pathogenicity and development in P. infestans are largely unknown, we have performed a large-scale phosphoproteomics study of six different P. infestans life stages. We have obtained quantitative data for 2922 phosphopeptides and compared their abundance. Life-sta
