Fluid flows shaping organism morphology

A dynamic self-organized morphology is the hallmark of network-shaped organisms like slime moulds and fungi. Organisms continuously re-organize their flexible, undifferentiated body plans to forage for food. Among these organisms the slime mould Physarum polycephalum has emerged as a model to investigate how organism can self-organize their extensive networks and act as a coordinated whole. Cytoplasmic fluid flows flowing through the tubular networks have been identified as key driver of morphological dynamics. Inquiring how fluid flows can shape living matter from small to large scales opens up many new avenues for research.Comment: 5 pages, 2 figures, perspectiv

Polynomial Rings and Topological Strings

An overview is given of the construction of a differential polynomial ring of functions on the moduli space of Calabi-Yau threefolds. These rings coincide with the rings of quasi modular forms for geometries with duality groups for which these are known. They provide a generalization thereof otherwise. Higher genus topological string amplitudes can be expressed in terms of the generators of this ring giving them a global description in the moduli space. An action of a duality exchanging large volume and conifold loci in moduli space is discussed. The connection to quasi modular forms is illustrated by the local P^2 geometry and its mirror, the generalization is extended to several compact geometries with one-dimensional moduli spaces.Comment: 10 pages, 2 figures, contribution to the proceedings of the String-Math 2013 conferenc

Exact Invariant Solutions for Generalized Invicid Burgers' Equation with Damping

In this work we study the Lie group analysis of a generalized invicid Burgers' equations with damping. Seven inequivalent classes of this generalized equation were classified and many exact and transformed solutions were obtained for each class.Comment: 16 page

How Should Translation Competence Be Taught: a Quest for a Better Approach in Translation Class

It is widely agreed that the main aim of translation education is to develop students' translation competence, therefore most researches in translation education contexts focus on identifying the components of transla-tion competence and appropriate curriculum models that integrate these components with suitable teaching strategies. Since translation competence consists of many sub-competences, developing these sub-competences therefore should be the main consideration in translation education. This article is aimed at discussing translation competence in general and how this competence should be de-veloped in a translation class context. Understanding these sort of things is important in formulating the best approach in translation teaching and learning in order to avoid the possible overlap between ‘translation teaching' and ‘language teaching', due to the fact that in some cases what the students get in translation class is not ‘how to be a good translator' but ‘how to be a good language learner'. Further, understanding the nature of students' translation competence and how this should be developed can give an important conceptual framework in formulating a better translation curriculum which considers all aspects the students need to build their translation competence.

Impact of Prenatal Checkups of Mothers and Immunization of Children on the Health Status of Children (0-3 years) - A Study in Rural areas of Aligarh District, Uttar Pradesh.

Background and objectives: A survey based study on rural areas of Aligarh District was conducted to assess the prenatal checkups pregnant women and its effects on health status of children between the age of (0-3 years), and immunization received by children and its effects on their health status. Methods: Five hundred children from five villages of rural areas of Aligarh District were randomly selected. For the purpose of the study, a self prepared structured interview schedule was used. To get the qualitative information of the study anthropometric measures include height weight were used for assessing growth pattern of the child. The stepwise analysis of two variables height for age and weight for age was done on the basis of Water low’s and Gomez’ classification. To examine the relationship between Health Status of the child and selected variable that affects Health Status of children, Chi-square test was employed. Results: Based on Gomez’ classification out of 88% mothers who did not go for prenatal ups majority 80% of children were underweight, and 80% of children who did not receive immunization majority 60% were underweight. Based on Waterlow’s classification majority 68% of children were stunted whose mother did not go for prenatal checkups and 50% of their children were stunted who did not receive immunization. Conclusion: Majority of children were stunted whose mother did not go for prenatal checkup and the children who did not receive immunization
