Abstract

Objective: To provide comprehensive literature survey of machining process in soda lime glass with reference to the conventional and non-conventional material removal process. Methods/Statistical Analysis: For more convenient understanding, the various processes, research and advanced progress in this field is presenting in table format. The ascending pyramid diagram shows progress of advanced researches on soda lime glass machining. The percent contribution of machining processes has been calculated and explained in a pie chart. Findings: There are totally eight machining processes used by various researchers to treat the soda lime glass. From which, Laser Machining Process and Electrochemical Discharge Machining Process showing highest contribution i.e. 22% are because of its advanced and wide range of applications in various fields. Whereas 6% contribution is observed for Abrasive Jet Machining process and micro grinding process, which is used at very low scale, it may be due to an extensive range of limitations. Application/Improvement: The present study is a first attempt towards the literature review on soda lime glass material. This review may be helpful to classify and select the most significant machining method to work with soda lime glass material.

Abstract

Stain removal is the process of removing a mark or spot left by one substance on a specific surface like fabric. The objective of present investigation is to formulate herbal stain removal for removing the stain from the fabrics. A solvent or detergent is generally used to conduct stain removal & many of these are available over another. In the present study stain removal was formulated by using herbal ingredients like Eucalyptus oil, Tween 80, Poloxomer, Citric acid, Carboxy methyl cellulose, Rose oil, Neem oil. The three different formulae were formulated viz. formula F1, formula F2 and formula F3. The six different samples of stain were used for observation of stain removal like tea, ketchup, ink, iodine, mud, blood. The action of prepared formulation was seen on these stained fabrics. All the formulations shows positive results and formula F3 was shows the best results than other formulations.

Keywords

Abstract

Objective. The purpose of this study was to investigate the stability of aqueous and oily ophthalmic solution of moxifloxacin fourth generation of fluoroquinolone. Method. The stability studies on the aqueous and oily ophthalmic formulations of moxifloxacin were carried out by exposing the formulations to accelerated (40° C and 75% RH) and room temperature storage conditions. During storage period, the formulations were periodically examined for pH and the remaining drug concentrations. Results. The accelerated and long term stability studies conducted on aqueous isotonic ophthalmic solutions of moxifloxacin indicate that moxifloxacin (0.5%, w/v) formulation of pH 7.2; containing, BAK (0.01%) and EDTA (0.01%) could provide a shelf life (t90) of 2 years, and the formulation appears promising from corneal permeation point of view. Among all the oily formulations, moxifloxacin (0.05%, w/v) ophthalmic solution in castor oil, with adequate overage, containing benzyl alcohol (0.5%, v/v) appears ideal from stability point of view. Conclusions. Presence of benzyl alcohol, however, appears necessary to maintain sterility of the formulation during use, as eye drops are normally dispensed in multi dose containers. The degradation of moxifloxacin was found to follow first order kinetics..
