the continuous addition of industrial, municipal, and agricultural effluents to the environment has led to a great increase of toxic pollutants. it is well known that these pollutants are hazardous to animals, plants, microorganisms, and other living organisms including humans. as a result, effective technologies should be developed to remove these contaminants. biological remediation, as an ec...

“When you are high, it is tremendous. Shyness goes, the right words and gestures are suddenly there, the power to seduce and captivate others a felt certainty. Feelings of ease, intensity, power, well-being, financial omnipotence and euphoria now pervade one’s marrow. But somehow, this changes. The fast ideas are far too fast and there are far too many, overwhelming confusion replaced by fear a...

Maxillectomy often leads to oralnasal or excessive oral-pharyngeal communication. The remaining teeth may need further preparation for various reasons, including crown or fixed dental prosthesis restoration. High-volume water is used in conjunction with highspeed tooth preparation to avoid the excessive heat generation that could endanger the health of the pulp. The water aerosol generated by t...

The photooxidation of thebaine (3) with a sun lamp affords two main products: hydrodibenzofuran 10 (major) and benzofuran 11 (minor). The latter compound becomes predominant if a Hg lamp is used instead of a sun lamp. The formation of 10 proceeds via an endoperoxide intermediate that undergoes oxidation at the nitrogen atom. Protection of the nitrogen either by protonation or quaternization pre...

in order to study the realationship between genetic diversity and different characteristics associated with grain yield in barley, 28 genotypes of barley cultivars contain seven cultivars and 21 hybrids were evaluated in randomized complete block (rcb) design with three replications. cultivars were valfajr, makuei, kavir, rayhan, gorgan, nusrat and nimroz. this study was carried out in research...

“Scrap Your Boilerplate” (SYB) is an established style of generic functional programming. The present paper reconstructs SYB within the Prolog language with the help of the univ operator and higher-order logic programming techniques. We pay attention to the particularities of Prolog. For instance, we deal with traversal of non-ground terms. We also develop an alternative model of SYB-like trave...

liposomes have attracted great interest as efficient carriers for nutrients, drugs and other bioactive agents as well as ideal models for biological membranes. this article intends to provide an overview of liposomes and nanoliposomes definition as well as their properties and preparation methods. also it elaborates on various applications of nanoliposomes in nanotherapy including diagnostics, ...
