INVESTIGATIONS ON THE DRUG-PROTEIN IN TERAC TION OF CERTAIN NEW POTENTIAL LOCAL ANAESTHETICS

Generally, plasma proteins owe their binding capacity to the presence of aminoacid units which enter into intra- and intermolecular hydrophobic bonding with a diverse range of endo- and exogenous chemical substances. The intermolecular interactions between the hydrophobic areas of drug molecules and those of plasma proteins play an important role in drug-macromolecular complex formation and...

Comparison of graphical and statistical methods in determining the number of sampling units in vegetation studies of desert ecosystems of South Khorasan

Background and objectives: Determining the minimum number of samples and the minimum parameters to be measured that provide acceptable results is one of the most basic decisions that rangeland scientists need to make. Methods for determining the number of samples in rangeland vegetation measurements are different. graphical methods and statistical characteristics are the most common methods by...

Local Unimodal Sampling

One of the simplest ways of optimizing a problem without knowledge of its gradient, is to iteratively and randomly pick a sequence of candidate solutions that improve on the fitness. This paper shows mathematically that to exhaust the optimum of a problem, the search-range from which the candidate solutions are picked, must be decreased during an optimization run. A simple technique for doing t...

Diversity of Plants and Animals in Mountain Ecosystems in Tajikistan

Tajikistan is a hotspot of plant and animal species diversity and endemism andis important for the conservation of biodiversity on a global scale. The country is located ata biological crossroads. Species from Central and Northern Europe, Central Asia, theMiddle East, and North Africa mingle here with endemics found nowhere else. Therichness of Tajikistan‘s biodiversity shows up at the genetic,...
