in the past decades, environmental pollution caused by plastic packing materials, restrictions of petroleum resources and their high price attracted many researchers to produce biodegradable packaging materials. poor mechanic properties and high water vapor permeability are two main defects of biodegradable polymers. nanotechnology is a modification method in this case. in the current study, th...

in this study 93 hirsute females (ferryman and gallway score > 8) referred to institute of endocrinology & metabolism and office were assessed. baseline testosterone (tes), dehydroepiandrosterane sulfate (dhea-so4). follicular stimulating hormone (fsh). leuteinizing hormone (lh), prolactin (prl), thyroid stimulating hormone (tsh), baseline 17 hydroxyprogesterone (17 ohp) and in some cases acth ...

This article aims to present with more details, the multicriteria decision aid SAPEVO-M-NC (Simple Aggregation of Preferences Expressed by Ordinal Vectors - Non-Compensatory Multi Decision Makers). It is a new version SAPEVO-M method, an ordinal, non-compensatory nature and possibility acting multiple makers. As result, method provides information on partial weights, indicating relative importa...

A technique is presented by which NC and RNC algorithms for some problems can be extended into NC and RNC algorithms, respectively, that solve more general parametric problems. The technique is demonstrated on explicit bounded degree circuits. Applications include parametric extensions of the shortest-path and spanning-tree problems and, in particular, the minimum-ratio-cycle problem, showing a...
