Abstract:: Formic acid (HCOOH) as an inexpensive and versatile reagent has attracted broad attention in the field of green synthesis and chemical industry. Formic acid acts not only as a convenient and less toxic CO surrogate, but also as an excel-lent formylative reagent, C1 source and hydrogen donor in organic reactions. Over the past decades, many exciting contribu-tions have been made which have helped chemists to understand the mechanisms of these reactions. The review will exam-ine recent advances in the utilization of formic acid as economical, practical and multipurpose reactant in synthetic trans-formations.

Heterocyclic compounds are indispensable organic structures because of their promising potential applications in medicinal, pharmaceutical and other related fields of chemistry. Exploring these heterocyclic compounds by evaluating metal nanoparticles as efficient nanocatalysts have attracted the researchers over the past decades, due to their stability, recyclability, reusability rather than conventional catalysts. Most of the nano-catalyzed organic reactions are taking place in benign and under green conditions. In this mini-review, we have documented synthesis of some of the recent N-containing heterocyclic compounds by utilizing advanced nanoparticles as effective catalysts. It has been concluded that exercising these nanocatalysts for the synthesis of N-containing heterocyclic compounds not only enhanced the yield of the product but has extensively increased the selectivity of the desired products via greener approach.

Nitrogen-containing heterocycles are one of the most common structural motifs in approximately 80% of the marketed drugs. Of these, benzimidazoles analogues are known to elicit a wide spectrum of pharmaceutical activities such as anticancer, antibacterial, antiparasitic, antiviral, antifungal as well as chemosensor effect. Based on the benzimidazole core fused heterocyclic compounds, crescent-shaped bisbenzimidazoles were developed which provided an early breakthrough in the sequence-specific DNA recognition. Over the years, a number of functional variations in the bisbenzimidazole core have led to the emergence of their unique properties and established them as versatile ligands against several classes of pathogens. The present review provides an overview of diverse pharmacological activities of the bisbenzimidazole analogues in the past decade with a brief account of its development through the years.

Storage Processes

The theory of storage processes, originally formulated by Moran [1] in 1954, has developed in the past fourteen years into a minor subfield of Applied Probability, closely allied to queueing theory. While dam models with discrete inputs are analogous to queueing processes, the essentially continuous nature of water inflows has distinguished generalized storage processes from queues. Indeed, some of the most complex of storage problems have arisen in the case of continuous flows.

In recent years, visible-light-mediated copper photocatalysis have emerged as an attractive strategy for the diverse constructions of basic bonds in an ecologically benign and cost-effective fashion. The intense activity and increasing work of these areas stimulated the exploit of the distinctive properties of copper photocatalysis and the rapid development and expansion of their applications. In this review, we focus on introducing a series of significant achievements in copper complexes as standalone photocatalysis in organic reactions to make an attempt to exhibit their potential capabilities and high flexibilities in synthetic chemistry.

It does not seem possible we are beginning year IV of PREP. Those who have been with us since the beginning will recall that the Pediatrics Review in Education Program, PREP, is designed as a six-year cycle. Each year objectives are developed by panels of pediatricians drawn from practice and teaching for two areas: Recent Advances of importance to the general pediatrician and Topics for Annual Review. Recent Advances cover the entire field of pediatrics, but are limited to information developed in the past six years; Topics are limited to a cluster area with no time limitation. For the 1982/83 Year, the Topics for Annual Review include community health, school health, accidents, poisoning and trauma, athletics and physical fitness, learning disabilities and school adjustment problems, adolescent medicine, delinquency, and drug abuse.
