What is the significance of three-dimensional structural similarity? This fundamental question still remains unanswered in spite of advances in automatic structure comparison methods that have been made in the last few years. The answer to this question will give us a much deeper insight into the principles of protein architecture.

Previous research has demonstrated that hemispheric asymmetries for conscious visual perception do not lead to asymmetries for unconscious visual perception. These studies utilized emotionally neutral items as stimuli. The current research utilized both emotionally negative and neutral stimuli to assess hemispheric differences for conscious and unconscious visual perception. Conscious perceptio...

This structural shift is concurrent with a greater emphasis on population health and the broad determinants of health. In parallel, there is a movement toward more intersectoral collaboration (i.e., collaboration between diverse segments of the health system, a...

We examined exposure to Internet pornography before the age of 18, as reported by college students (n = 563), via an online survey. Ninety-three percent of boys and 62% of girls were exposed to online pornography during adolescence. Exposure prior to age 13 was relatively uncommon. Boys were more likely to be exposed at an earlier age, to see more images, to see more extreme images (e.g., rape,...

In India, 70-80% population of the country depends directly or indirectly to farming. So this field is very much important for research and the concept of contract farming is more important for farmers and other persons who are joined with this. There are so many models of contract farming and many of them are explained by authors in this paper. Many advantages and issues related to contract fa...

This paper is motivated by R. H. Bruck’s paper[3], in which he proved that the existence of cyclic projective plane of order n ≡ 1 (mod 3) implies that of a non-planar difference set of the same order by proving that such a cyclic projective plane admits a regular non-Abelian automorphism group using n as a multiplier. In this paper we will discuss in detail the possibility of using multipliers...
