 Abstract

The concentration measurements of various solutions are of great interest in many of industrial processes as a mean of quality production control. In this paper the Fiber Bragg Grating is fabricated by phase mask technique on single mode Ge-B co-doped photosensitive fiber with KrF (248 nm) source. The grating region etched with HF (40%) to act as a concentration sensor, which affects the resonance wavelength with change in surrounding media (hydrogen peroxide) concentration. We have analyzed hydrogen peroxide for various low level concentrations in the range of 1-12 ppm level. The sensor acts effectively sensitive to small changes in hydrogen peroxide concentration.

 Abstract

In the last several decades, the application of nanomedicine for clinical purposes has received significant attention from academia, researchers, government, funding agencies, and regulatory bodies. Key issues related to the clinical development of nanoparticulate nanomedicines include biological challenges, biocompatibility and safety, large scale manufacturing, government regulations, intellectual property (IP), and overall cost-effectiveness in comparison to current therapies. This review focuses on the introduction of nanoparticles and various challenges face by these formulations, controversy associated with the basic concept related to the nano systems. Nanoparticles based formulations have ability to overcome biological barriers to effectively deliver them from biological sites, despite of their advantages only small number of nanoparticles-based formulations get approved for clinical use with numerous challenges and hurdle at different stages of development. The biocidal activity of Metal nanoparticles in general and silver nanoparticles (AgNPs) depends on several morphological and physicochemical characteristics of the particles. Many of the interactions of the AgNPs with the human body are still poorly understood; hence, the most desirable characteristics for the AgNPs are not yet well established. This shows that with the regulatory issues related to nanomedicines there are also several pharmacological and toxicological issues which have to consider during synthesis of nanomedicines. This review summarizes challenges likely to be encountered during the development and approval of nanoparticle-based therapeutics, and discusses potential strategies for drug developers and regulatory agencies to accelerate the growth of this important field.

 Abstract

Callistemon viminalis is commonly known as bottle brush plant belonging to family myrtaceae it a god great medicinal impoartance is ethnic trialcommunities which are still in practice the present study deals with the pharmacognostic studies including examination of morphological and microscopical characters. The essential volatile oil was extracted by hydrodistillation method from leaves of callistemon viminalis. The chemical composition of volatile oil was studied by performing its GC study and this project is review on the study of extracted essential volatile oil from leaves of Callistemon viminalis which acts as antibacterial, antifungal, haemolytic, antiviral properties.

 Abstract

The objective of this work is to review on ginger powder and oil of cloves herbal toothpaste. In current scenario in oral tending with use of herbal toothpaste containing natural ingredients are more acceptable publicly belief than chemical based synthetic use thanks to their safety and efficacy in reducing decay, and preventing other dental issues to which this generation is liable to. Cloves are the best medicinal value which are employed in Ayurveda. Oils, dried flower buds, leaves, and stems are wont to produce medication. Clove is that the most typically used on to the gums for toothaches , pain relief during dental work , and other dental concern . oil of cloves contains a chemical called eugenol that will help to decrease pain and fight infection. Zingiber officinale, belonging to the ginger family , may be a popular herb and it's been used as a spice and a drugs . Ginger is a vital plant with several medicinal and nutritional values in Asian and Chinese . Gingerol has long been use as an herbal medicine to treat various symptoms including pain in toothaches, and it's shown anti-inflammatory properties. a very important extension of this early work was the observation that ginger also suppresses leukotriene biosynthesis by inhibiting 5-lipoxygenase.

What shall we required of poetry? Delight, music subtlety of thought, a world of the heart's Desire, fidelity to comprehensible experience, a glimpse through magic casements profound wisdom? All these things all different, yet not all contradictory have been required of poetry. What shall we require of her? The answer comes it seems, as quick and as vague as the question. We require the highest
