background: families with disabled children need more psycho-social considerations. motherhood care of the children with multiple disabilities is difficult. due to its importance, the aim of this study was to investigate the causal factors affecting loving care of mothers of children with multiple disabilities. methods: the study used a cross-sectional method in which 75 mothers of exceptional ...

in western countries we assist at the paradox that fertility is socially discouraged by a mindset that depicts fertility as a resource to exploit as late as possible. so, couples have high expectative about the advantages of delayed parenthood, but they are scarcely informed about its risks. scientific data suggests to anticipate the first pregnancy, but social pressures impose to wait, though ...

BACKGROUND There are multiple models of mental illness that inform professional and lay understanding. Few studies have formally investigated psychiatrists' attitudes. We aimed to measure how a group of trainee psychiatrists understand familiar mental illnesses in terms of propositions drawn from different models. METHOD We used a questionnaire study of a sample of trainees from South London ...

Periodic crystal diffraction is described using a three-dimensional (3D) unit cell and 3D space-group symmetry. Incommensurately modulated crystals are a subset of aperiodic crystals that need four to six dimensions to describe the observed diffraction pattern, and they have characteristic satellite reflections that are offset from the main reflections. These satellites have a non-integral rela...

We give necessary conditions for the existence of perturbative heterotic and common sector type II string warped compactifications preserving four and eight supersymmetries to four spacetime dimensions, respectively. In particular, we find that the only compactifications of heterotic string with the spin connection embedded in the gauge connection and type II strings are those on Calabi-Yau man...

BACKGROUND The majority of adolescents in Africa experience pregnancy, childbirth and enter motherhood without adequate information about maternal health issues. Information about these issues could help them reduce their pregnancy related health risks. Existing studies have concentrated on adolescents' knowledge of other areas of reproductive health, but little is known about their awareness a...

We investigate the nonlinear realization of spontaneously broken N = 2 superconformal symmetry in 4 dimensions. We particularly study NambuGoldstone degrees of freedom for the partial breaking of N = 2 superconformal symmetry down to N = 1 super-Poincaré symmetry, where we get the chiral NG multiplet of dilaton and the vector NG multiplet of NG fermion of broken Q-supersymmetry. Evaluating the ...

We construct infinite families of topologically isotopic, but smoothly distinct knotted spheres, in many simply connected 4-manifolds that become smoothly isotopic after stabilizing by connected summing with S2×S2, and as a consequence, analogous families of diffeomorphisms and metrics of positive scalar curvature for such 4-manifolds. We also construct families of smoothly distinct links, all ...

Topological models involving matter couplings to Donaldson-Witten theory are presented. The construction is carried using both, the topological algebra and its central extension, which arise from the twisting of N = 2 supersymmetry in four dimensions. The framework in which the construction is based is constituted by the superspace associated to these algebras. The models show new features of t...
