Finite element modelling of inter-ply delamination and intra-yarn cracking in textile laminates

The aim of the current study is to demonstrate the effect of inter-ply delamination on stiffness degradation of multi-ply woven composites. Such a demonstration becomes possible due to new technique of modelling textile laminates. It is based on set of boundary value problems for unit cell of a single ply, where boundary conditions imitate interaction with the other plies. Once these problems are solved, local stress distribution and stiffness of the laminate are determined analytically as function of number of the plies and local stress/strain fields obtained in these problems. Hence, it opens the road for an efficient modelling of delamination, which is described as gradual reduction of plies in the laminate

Analysis of the Literary Text's Conceptosphere in the Process of Teaching Literary Translation

AbstractThe paper is devoted to the problem of the concept “painting” realization in the “Moon and sixpence” by S. Maugham. It is argued that application of cognitive discourse analysis and analysis of the conceptosphere of the literary text is helpful in overcoming difficulties in interpretation of the original literary text. Various methods of studying literary text existing in modern methodology are shown. The contribution of Russian and foreign science in determining approaches to the analysis of communicative and cognitive components of the text and application of interdisciplinary approaches and consideration of cultural aspects of literary texts of the target language are emphasized. The need for incorporating development of important translational competences into the process of carrying out cognitive-discourse analysis of the literary text is demonstrate

On Homoclinic Solutions of a Semilinear -Laplacian Difference Equation with Periodic Coefficients

We study the existence of homoclinic solutions for semilinear -Laplacian difference equations with periodic coefficients. The proof of the main result is based on Brezis-Nirenberg's Mountain Pass Theorem. Several examples and remarks are givenA.

Impulsive aggressiveness of pregnant women affects the development of the fetal heart

Mounting evidence indicates that the development of the fetus is heavily influenced by the intra-uterine milieu during pregnancy, and that such influence may have life-long consequences for the individual. The intra- uterine milieu is not only influenced by nutritional factors, but also by maternal endocrine and autonomic activity. Such activity is prone to be affected by an individual's personality, but only little is known about influences of maternal personality on the development of the fetus. We tested pregnant women for their propensity for impulsive, uncontrollable outbursts of temper (referred to here as moderate Intermittent Explosive Disorder, mIED). After the women gave birth, we measured electrocardiograms (ECGs) from their newborn infants to compare ECGs between newborns of women with and without mIED. The data show that infants of women with mIED have larger QRS complexes in the electrocardiogram, and lower heart rate variability, compared to infants of women without mIED. These results reveal effects of maternal mIED on the fetal heart development. These effects may predispose the individual to increased risk for later cardio-vascular disease. The findings open perspectives for better risk prevention models for the unborn child
