The Verwey transition in Fe3O4 is the first metal-insulator transition caused by charge ordering. However, the physical mechanism and influence factors of Verwey transition are still debated. Herewith, the strain effects on the electronic structure of low-temperature phase (LTP) Fe3O4 with P2/c and Cc symmetries are investigated by first-principles calculations. LTP Fe3O4 with each space group ...

This Part II continues our paper [BGI], but we have made it as independent of that paper as possible. The reader familiar with the self-contained essay on finitary sheaves and finitary maps which is §4 of [BGI] can read this second paper with occasional references back to [BGI] for some details and analogies. A full outline of the present paper is found in §10 below. Let G be a group, let M be ...

The purpose of the study was to investigate into flow Russian scientific publications on basis various information systems and statistical data determine if they can be used for forecasting science devеlopment, specify its place in global space knowledge. definitions several discussable concepts are suggested. Sources methods . bibliometrical assessment publication flows namely: Science Citatio...

Chylothorax is a relatively uncommon condition defined as an abnormal collection of lymphatic fluid within the pleural space. Morbidity of congenital chylothorax (CC) is high, and prognosis is very poor if CC is associated with hydrops fetalis. Although the optimal treatment of CC has not been determined, conservative treatment and surgical intervention are employed. However, there is still lit...

Distributed sources are included in the Einstein equations. Such modification of the general relativity provides a simple description of the accelerated expansion of the Universe with a dynamical scaling. Distributed sources can also be applied to more local cosmological phenomena, which defy conventional explanation. A possibility of superluminary effects is indicated. The Einstein equations f...

The growth rate and albumin concentration of interstitial fluid cuffs were measured in isolated rabbit lungs inflated with albumin solution (3 g/dl) to constant airway (Paw) and vascular pressures for up to 10 h. Cuff size was measured from images of frozen lung sections, and cuff albumin concentration (Cc) was measured from the fluorescence of Evans blue labeled albumin that entered the cuffs ...

Calcium (Ca) and phosphorus (P) dynamics in Shaver White hens (19-63 wk of age) were compared between enriched (EC) and conventional cage (CC) systems. Calcium and P intake and their levels in egg components and excreta were considered. Using commercial levels of production (4,836 hens), 10 test cages/system (24 hens/test cage) were used as replicate units. Enriched cages provided a nesting are...

The aim of this study was to assess the influence of the handgrip test (HGT) on: (1) pial artery pulsation (cc-TQ), (2) subarachnoid space (SAS) width (sas-TQ) and (3) the relationship between peripheral blood pressure (BP), heart rate (HR), cerebral blood flow velocity (CBFV), resistive index (RI), cc-TQ and sas-TQ. The study was performed on 29 healthy volunteers (11 men and 18 women) with a ...

Small peptides are model molecules for the amino acid residues that are the constituents of proteins. In any bottom-up approach to understand the properties of these macromolecules essential in the functioning of every living being, to correctly describe the conformational behaviour of small peptides constitutes an unavoidable first step. In this work, we present an study of several potential e...

OBJECTIVE To describe the results of different statistical ways of addressing radiographic outcome affected by missing data--multiple imputation technique, inverse probability weights and complete case analysis--using data from an observational study. METHODS A random sample of 96 RA patients was selected for a follow-up study in which radiographs of hands and feet were scored. Radiographic p...
