Hydrogen Sorption in the LiH-LiF-MgB2 System

A composite material in the LiH-LiF-MgB2 system has been synthesized by high-energy ball milling. Some peaks in addition to that of the binary 2LiH-MgB2 and 2LiF-MgB2 systems are observed for the composite material by high-pressure differential scanning calorimetry (HP-DSC), indicating the formation of intermediate phases. In situ synchrotron radiation powder X-ray diffraction (SR-PXD) performed a

Monoamine theories of depression: historical impact on biomedical research

Monoamine theories associate depression with reduced brain monoamine levels. These theories achieved broad popularity in the mid-1960s. The present article reviews the historical development of monoamine theories and their subsequent impact on biomedical research. Alleged divisions between West European and U.S. researchers over competing versions of the theories are investigated using bibliometri

Why, when and how did yeast evolve alcoholic fermentation?

The origin of modern fruits brought to microbial communities an abundant source of rich food based on simple sugars. Yeasts, especially Saccharomyces cerevisiae, usually become the predominant group in these niches. One of the most prominent and unique features and likely a winning trait of these yeasts is their ability to rapidly convert sugars to ethanol at both anaerobic and aerobic conditions.

Body mass index is associated with biological CSF markers of core brain pathology of Alzheimer's disease

Weight changes are common in aging and Alzheimer's disease (AD) and postmortem findings suggest a relation between lower body mass index (BMI) and increased AD brain pathology. In the current multicenter study, we tested whether lower BMI is associated with higher core AD brain pathology as assessed by cerebrospinal fluid (CSF)-based biological markers of AD in 751 living subjects: 308 patients wi

IgG glycan hydrolysis by endoglycosidase S diminishes the proinflammatory properties of immune complexes from patients with systemic lupus erythematosus: A possible new treatment?

Objective Systemic lupus erythematosus (SLE) is an autoimmune disease with chronic or episodic inflammation in several organ systems, related to the presence of circulating and tissue-deposited immune complexes (ICs) that stimulate leukocytes through Fc? receptors (Fc?R) with subsequent inflammation. Treatment with endoglycosidase S (EndoS), an IgG glycanhydrolyzing bacterial enzyme from Streptoco

Mechanical aspects of installation of integrated magnets at Solaris synchrotron storage ring

Solaris synchrotron storage ring which has been assembled at the beginning of the 2015, consist of twelve integrated magnets blocks performing the part of double bend achromat. Both magnets as well as the whole ring as concept is a replica of Max IV 1.5 GeV ring and utilize pioneering integrated magnets approach. Solaris ring assembly forewent that of its Swedish twin. It is a successful proof of

Premedication for intubation with morphine causes prolonged depression of electrocortical background activity in preterm infants.

Background:Sedative and analgesic medications are used in critically ill newborns, but little is known about their effects on electrocortical activity in preterm infants. We hypothesized that morphine might induce prolonged neurodepression, independent of blood pressure, compared with rapid sequence induction/intubation (RSI).Methods:Of 34 infants enrolled into a randomized controlled trial (RCT)

Subdecoherence Time Generation and Detection of Orbital Entanglement in Quantum Dots

Recent experiments have demonstrated subdecoherence time control of individual single-electron orbital qubits. Here we propose a quantum-dot-based scheme for generation and detection of pairs of orbitally entangled electrons on a time scale much shorter than the decoherence time. The electrons are entangled, via two-particle interference, and transferred to the detectors during a single cotunnelin

Contribution of Subregions of Human Frontal Cortex to Novelty Processing

Abstract in UndeterminedNovelty processing was studied in patients with lesions centered in either OFC or lateral pFC (LPFC). An auditory novelty oddball ERP paradigm was applied with environmental sounds serving as task irrelevant novel stimuli. Lesions to the LPFC as well as the OFC resulted in a reduction of the frontal Novelty P3 response, supporting a key role of both frontal subdivisions in

Arsenic adsorption by iron-aluminium hydroxide coated onto macroporous supports: Insights from X-ray absorption spectroscopy and comparison with granular ferric hydroxides.

This paper evaluates the arsenic adsorption characteristics of a macroporous polymer coated with coprecipitated iron-aluminium hydroxides (MHCMP). The MHCMP adsorbent-composite fits best with a pseudo-second order model for As(III) and a pseudo-first order kinetic model for As(V). The MHCMP shows a maximum adsorption capacity of 82.3 and 49.6mgAs/g adsorbent for As(III) and As(V) ions respectively

Formation of macroporous self-assembled hydrogels through cryogelation of Fmoc-Phe-Phe.

In this study, it was found that macroporous hydrogels were formed when self-assembly of fluorenyl-9-methoxycarbonyl (Fmoc)-diphenylalanine (Phe-Phe) peptides was induced using glucono-δ-lactone (GdL) in apparently frozen samples. Formed cryogels exhibited a heterogeneous structure with pore walls of densely packed fibres of assembled dipeptides and pores in the range 10-100μm. Hydrogels formed fr

Children's experiences of acute hospitalisation to a paediatric emergency and assessment unit--a qualitative study.

Short-stay treatment has become a popular form of care as a strategy to cope with increased demands on health care. There is little research that considers children's experiences of acute hospitalisation to a short-stay care facility such as a Paediatric Emergency and Assessment Unit (PEAU). This study explored the experiences of eight children aged 8-10 years. Semi-structured interviews were carr

Formalisation and flexibilisation in organisations - Dynamic and selective approaches in corporate innovation processes

A classic problem in organising corporate innovation projects is the tension between formalisation and flexibilisation. Connecting this discussion to the younger debate on ambidexterity, this paper asks how organisations balance informal and formal, flexible and inflexible ways of working in their innovation projects. It derives a way to break down formalisation and flexibilisation into the dimens

Fiscal Incentives, Public Spending, and Productivity – County-Level Evidence from a Chinese Province

This article develops a new empirical approach to analyze the potential link between fiscal decentralization and economic efficiency based on a stochastic frontier model with spatial error correction. Fiscal decentralization is not considered to be a source of growth in itself but an incentive scheme that impacts local governments’ spending as a means to improve investment conditions. Panel data f

Tropospheric Photolysis Rates of the Acetaldehyde Isotopologues CD3CHO and CD3CDO Relative to CH3CHO Measured at the European Photoreactor Facility.

Acetaldehyde is a hazardous pollutant found in indoor and ambient air. Acetaldehyde photolysis is pressure- and wavelength-dependent with three distinct product channels. In this study, the photolysis rates of CH3CHO, CD3CDO, and CD3CHO are studied in natural tropospheric conditions using long path FTIR spectroscopy, at the European Photoreactor Facility (EUPHORE) in Valencia, Spain. The average r

Search for Dilepton Resonances in pp Collisions at root s 7 TeV with the ATLAS Detector

This Letter reports on a search for narrow high-mass resonances decaying into dilepton final states. The data were recorded by the ATLAS experiment in pp collisions at root s = 7 TeV at the Large Hadron Collider and correspond to a total integrated luminosity of 1.08 (1.21) fb(-1) in the e(+)e(-) (mu(+)mu(-)) channel. No statistically significant excess above the standard model expectation is obse
