Quantifying Dispersion in Graphene Oxide/Reactive Benzoxazine Monomer Nanocomposites

Two structurally different bisbenzoxazine monomers (tBP-oda and tBP-jeff(148)) are synthesized and reinforced with graphene oxide (GO) at concentrations ranging from 0.25 to 3 wt %. Successful synthesis of the benzoxazine monomer and conversion from graphite to GO are verified by proton nuclear magnetic resonance spectroscopy (H-1 NMR), Fourier transform infrared spectroscopy (FT-IR), and X-ray di

Nailfold capillaroscopy in systemic sclerosis: Data from the EULAR scleroderma trials and research (EUSTAR) database

Objective: The aims of this study were to obtain cross-sectional data on capillaroscopy in an international multi-center cohort of Systemic Sclerosis (SSc) and to investigate the frequency of the capillaroscopic patterns and their disease-phenotype associations. Methods: Data collected between June 2004 and October 2011 in the EULAR Scleroderma Trials and Research (EUSTAR) registry were examined.

The Ycf54 protein is part of the membrane component of Mg-protoporphyrin IX monomethyl ester cyclase from barley (Hordeum vulgare L.)

The biosynthesis of chlorophyll has been demonstrated to require an extensive set of enzymes, the initial stages of which are shared with the synthesis of heme. Of these enzymes, the most enigmatic is the Mg-protoporphyrin IX monomethyl ester cyclase (EC 1.14.13.81). This enzyme requires components found associated with the plastid membrane and the plastid soluble fraction. One of the components,

Old Wine in New Bottles? The Legitimation and Delegitimation of UN Public-Private Partnerships for Sustainable Development from the Johannesburg Summit to the Rio+20 Summit

Global public-private partnerships for sustainable development have been framed as new instruments that can increase the democratic credentials and effectiveness of global governance. This article revisits 10 years of scholarship and practice of the 348 Johannesburg partnerships, adopted at the 2002 World Summit on Sustainable Development and reaffirmed at the UN Rio+20 summit in 2012. The article

Comparative analysis of quantum cascade laser modeling based on density matrices and non-equilibrium Green's functions

We study the operation of an 8.5 mu m quantum cascade laser based on GaInAs/AlInAs lattice matched to InP using three different simulation models based on density matrix (DM) and non-equilibrium Green's function (NEGF) formulations. The latter advanced scheme serves as a validation for the simpler DM schemes and, at the same time, provides additional insight, such as the temperatures of the sub-ba

Parameter estimation for compact binary coalescence signals with the first generation gravitational-wave detector network

Compact binary systems with neutron stars or black holes are one of the most promising sources for ground-based gravitational-wave detectors. Gravitational radiation encodes rich information about source physics; thus parameter estimation and model selection are crucial analysis steps for any detection candidate events. Detailed models of the anticipated waveforms enable inference on several param

The TFPI-2 Derived Peptide EDC34 Improves Outcome of Gram-Negative Sepsis.

Sepsis is characterized by a dysregulated host-pathogen response, leading to high cytokine levels, excessive coagulation and failure to eradicate invasive bacteria. Novel therapeutic strategies that address crucial pathogenetic steps during infection are urgently needed. Here, we describe novel bioactive roles and therapeutic anti-infective potential of the peptide EDC34, derived from the C-termin

The dual regulator Sufu integrates Hedgehog and Wnt signals in the early Xenopus embryo

Hedgehog (Hh) and Wnt proteins are important signals implicated in several aspects of embryonic development, including the early development of the central nervous system. We found that Xenopus Suppressor-of-fused (XSufu) affects neural induction and patterning by regulating the Hh/Gli and Wnt/beta-catenin pathways. Microinjection of XSufu mRNA induced expansion of the epidermis at the expense of

Toxicity-Reducing Potential of Extracorporeal Affinity Adsorption Treatment in Combination With the Auristatin-Conjugated Monoclonal Antibody BR96 in a Syngeneic Rat Tumor Model

BACKGROUND: Antibody-drug conjugates, comprising monoclonal antibodies (MoAbs) that bind to tumor-associated antigens, display different toxicity profiles compared with radiolabeled MoAbs. Dose-limiting toxicities may include damage to the liver and myelotoxicity. The drug component is the antimitotic agent auristatin, which is 1001000 times more potent than doxorubicin. Consequently, auristatin a

The hunt for the Milky Way's accreted disc

The Milky Way is expected to host an accreted disc of stars and dark matter. This forms as massive greater than or similar to 1 : 10 mergers are preferentially dragged towards the disc plane by dynamical friction and then tidally shredded. The accreted disc likely contributes only a tiny fraction of the MilkyWay's thin and thick stellar disc. However, it is interesting because (i) its associated '

Type- and age-specific distribution of human papillomavirus in women attending cervical cancer screening in Finland

Background: Large-scale data on type-specific HPV prevalences and disease burden are needed to monitor the impact of HPV vaccination and to plan for HPV-based cervical screening. Methods: 33 043 women (aged 25-65) were screened for HPV by a Hybrid Capture 2 (HC2) in a population-based programme. HPV-positive women (n = 2574) were triaged by cytology and HPV genotyped using PCR-Luminex. Type-specif

Local levers for change: Mainstreaming ecosystem-based adaptation into municipal planning to foster sustainability transitions

Unprecedented global challenges demand wide-reaching societal modification to ensure life support functions and human well-being. In the absence of adequate international responses to climate change and the need for place-based adaptation, local governments have a pivotal role in fostering sustainability transitions. In this context, the importance of ecosystem-based adaptation is increasingly rec

Perfectionism and sense of coherence among patients with eating disorders.

Background: There is a substantial body of research on eating disorders and perfectionism. Also there are several studies on eating disorders and sense of coherence (SOC), but studies regarding all three subjects are sparse. Perfectionism and the degree of SOC are considered central and aggravating aspects of psychiatric conditions, not least in relation to eating disorders. Aims: The present stud

Biobreeding rat islets exhibit reduced antioxidative defense and N-acetyl cysteine treatment delays type 1 diabetes

Islet-level oxidative stress has been proposed as a trigger for type 1 diabetes (T1D), and release of cytokines by infiltrating immune cells further elevates reactive oxygen species (ROS), exacerbating beta cell duress. To identify genes/mechanisms involved with diabeto-genesis at the beta cell level, gene expression profiling and targeted follow-up studies were used to investigate islet activity

Mortality, attempted suicide, re-hospitalisation and prescription refill for clozapine and other antipsychotics in Sweden-a register-based study

PurposeThe aim of this study was to analyse prescription refill, re-hospitalisation, total mortality, mortality because of suicide and attempted suicide among patients who were taking various types of antipsychotics. MethodsA population-based cohort study analysed all patients (n=26046) in Sweden who had been treated for schizophrenia from 2006 to 2009 with regard to re-hospitalisation and prescri

Spreading Dynamics of a Functionalized Polymer Latex.

Functionalized polymer nanoparticles are used as binders for inorganic materials in everyday technologies such as paper and coatings. However, the functionalization can give rise to two opposing effects: It can promote adhesion via specific interactions to the substrate, but a high degree of functionalization can also hamper spreading on substrates. Here, we studied the spreading kinetics of indiv

D-A(1)-D-A(2) Copolymers with Extended Donor Segments for Efficient Polymer Solar Cells

Typically a donor-acceptor (D-A) design strategy is used for engineering the bandgap of polymers for solar cells. However, in this work, a series of alternating D-A(1-)D-A(2) copolymers PnTQTI(F) were synthesized and characterized with oligothiophenes (nT, n = 1, 2, 3) as the donor and two electron-deficient moieties, quinoxaline and isoindigo, as the acceptors in the repeating unit. We have studi

Operational Improvements for Startup Time Reduction in Solar Steam Turbines

Solar steam turbines are subject to high thermal stresses as a result of temperature gradients during transient operation, which occurs more frequently due to the variability of the solar resource. In order to increase the flexibility of the turbines while preserving lifting requirements, several operational modifications for maintaining turbine temperatures during offline periods are proposed and
