We investigate the local regularity of pointed spacetimes, that is, timeoriented Lorentzian manifolds in which a point and a future-oriented, unit timelike vector (an observer) are selected. Our main result covers the class of Einstein vacuum spacetimes. Under curvature and injectivity bounds only, we establish the existence of a local coordinate chart defined in a ball with definite size in wh...

in order to study of genetic diversity and similarity among four native olive cultivars including ‘mari’, ‘zard’, ‘shengeh’ and ‘rowghani’, these cultivars were evaluated in five regions including ali abad, gilvan, tarom, manjil and jamal abad at 2012-2013. there was a significant difference among studied individuals. the correlation coefficient analysis among studied traits showed that there w...

Broadband communications lie at the heart of the developing information society. Employing a logistic diffusion model, we analyze the factors that influence the diffusion of fixed and mobile broadband. For fixed broadband diffusion, we find that local loop unbundling, income, population density, education, and price are significant factors of fixed broadband diffusion. For mobile broadband, mul...

We study the empirical consistency of survey based (micro level) indicators of social capital and local government performance on the one, and municipality based (aggregate level) measures of these two concepts on the other hand. Knowledge about the behavior of these indicators is helpful for evaluating the value of studies carried out in isolated contexts, that is, with access to data on eithe...

The use of local anaesthetic techniques varies with the anaesthetist's working conditions, direction of interest, and hence geographically. Thus they are mainly used in certain centres in America and Canada, and in the Scandinavian countries. Interest in, and use of, local anaesthesia has increased during the last decade. There are many reasons for this. The use of these techniques enables the ...
