Dendritic macromolecules’ have attracted much attention as organic examples of well-defined nanostructures. These molecules are ideal model systems for studying how physical properties depend on molecular size and architecture. In this paper using a simple result, some GAP programs are prepared to compute Wiener and hyper Wiener indices of dendrimers.

Nowadays, the products/systems project has demanded the inclusion of maintainability characteristics in order to facilitate support activities, and, so, to reduce the time of intervention used for repair, life cycle cost, and improvement of availability and operational regularity. This work develops a scale evaluation model of the maintainability indexes, using value functions acquired with the...

As serial femtosecond crystallography expands towards a variety of delivery methods, including chip-based methods, and smaller collected data sets, the requirement to optimize the data analysis to produce maximum structure quality is becoming increasingly pressing. Here cppxfel, a software package primarily written in C++, which showcases several data analysis techniques, is released. This soft...

BACKGROUND Anemia affects a high proportion of pregnant women in the developing countries. Factors associated with it vary in context. This study aimed to determine the prevalence and predictors of anemia among pregnant women in the rural eastern Ethiopia. METHODS A community-based cross-sectional study was done on 1678 pregnant women who were selected by a cluster random sampling technique. ...
