For centuries, herbal drugs have been the only accessible resource for treatment of pain and passions. Today, despite remarkable progress and development of synthetic drugs, medicinal plants and their derived drugs are used massively. So that, in some countries medicinal plants is inseparable from drugs and treatment systems. More ever, their marketing and economical aspects are more flourishin...

in this paper, the present state of knowledge about axial mixing in gasliquid reactors is reviewed. a brief outline of the methods for measuring residence time distribution(rtd)of various phases in a multiphase reactor is presented. this is followed by a short description of differential and stage-wise models for characterizing back mixing from rtd measurments. backmixing characteristics of som...

lead is a relatively ubiquitous heavy metal with particular features such as resistance to corrosion, high malleability and wide variety of industrial applications. in medicine, however, it is considered as a slow-acting toxic substance affecting multiple body systems, specifically functioning as a potent neurotoxin in the central nervous system. lead poisoning may be acute or chronic and can b...

Storing and manipulating Big Data relies on various data structures, algorithms and technologies. Some of these are new, while others have existed for quite a while (the Bloom filter was presented in 1970) and are now making their way into mainstream software engineering. We present those algorithms and technologies briefly, and provide citations for further reading. This paper is organized as ...

Traditional data envelopment analysis (DEA) models deal with measurement of relative efficiency of decision making units (DMUs) in which multiple-inputs consumed to produce multiple-outputs. One of the drawbacks of these models is neglecting internal processes of each system, which may have intermediate products and/or independent inputs and/or outputs. In this paper some methods which are usab...

Recent years have witnessed increasing awareness and interest in rare earth elements (REE). These several, usually unfamiliar elements, are key components of countless products used our daily lives. Because their use many modern technologies, including those important for national security, the demand REE grows, so does production, need to find new sources improve extraction. This article provi...

Glycation, the non-enzymatic binding of glucose to free amino groups of an amino acid, yields irreversible heterogeneous compounds known as advanced glycation end products. Those products play a significant role in diabetic complications. In the present article we briefly discuss the contribution of advanced glycation end products to the pathogenesis of diabetic complications, such as atheroscl...

are free will and causal determinism compatible with each other? this is one of the most important questions central to discussions relating to free will. the problem is that causal determinism makes us encounter challenging dilemmas, either way leading us to deny free will: (1) causal determinism is either true or not true; (2) if causal determinism is true, we do not have free will; since all...
