NON-DESTRUCTIVE RAMAN SPECTROSCOPIC METHOD FOR ESTIMATION OF MONTELUKAST FROM TABLET DOSAGES FORM

Objective: A rapid, non-destructive and non-solvent raman spectroscopic method for estimation of Montelukast from tablet dosages form Methods: Quantification was carried out by measuring the intensity of analyte peak at 1440 cm-1. Each Raman spectrum corresponded to an accumulation of 4 scans with an exposure time of 5 sec for each scan with a total integration time of 20 sec.Results: The method exhibited linearity between 2 mg-24 mg show well resolve quantification From MON. The linearity equation was calculated as y = 13.036x+70.819 and the correlation coefficient was found to be 0.997 for MON. LOD (limit of detection) and LOQ(limit of quantification) values were calculated using the calibration curve slope and standard deviation of the response. The LOD (limit of detection) and LOQ (limit of quantification) values were found to be 1.71 mg and 5.13 mg respectively.Conclusion: The developed method was successfully applied for assay of montelukast in the intact formulation. The method was validated according to an international conference on harmonisation guidelines. A recent study, montelukast sodium had been analysed by the raman method, but, looking into the tremendous potential of raman spectroscopic method; it can be extended as a process analysis and technology tool in various quality checks during manufacturing of pharmaceutical products

Emerging technologies to sustainability: A comprehensive study on solar desalination for sustainable development

ABSTRACT: Due to global warming and the salinity of drinkable natural resources, water scarcity has become a significant impediment to the development of many regions of the world, prompting the development of novel desalination techniques for brackish and seawater. The only way to satisfy society's freshwater demands is to transform abundant seawater into potable water by desalination. Numerous research efforts have been effective in establishing large desalination plants. However, significantly fewer attempts are made for dry regions where low-cost, maintenance-free, and low-operational-cost approaches are required. Both rapidly developing and underdeveloped nations struggle to provide their populations with pure drinking water. In the desalination sector, CO2 emissions and significant ecological problems have increased. The desalination sector may be sustainable by integrating renewable energy and using proper brine disposal techniques. In this review, various desalination systems that incorporate renewable energy sources, with an emphasis on solar energy, are examined. The main objective of this paper is to explain what solar desalination is, why it is performed, and what techniques can be used to make desalination more structured and cost-effective. In addition, this study provides a comprehensive review of all the solar desalination systems, indirect and direct, along with plant-specific technical data. In addition, the efforts that have been made to evaluate the economic viability of each desalination technology and the elements that determine its cost are discussed

Gujarati Character Identification: A Survey

Abstract: English Character Recognition techniques have been studied extensively in the last two decades and it gain unbelievable high progress and success ratio. But for regional languages these are still emerging and their success ratio is very poor. In Gujarat, there are thousands of people who can speak, write and understand only Gujarati language. Rapid growing computation may increase Indian CR methodology. Today the whole world is digitized. And heavy demand of digital documentation in any field like postal services, publishing house, automation, data entry, text entry and communication technology. Gujarati is mother tongue of Gujarat, spoken by thousands of people. There is less development in this area due to complexity in script. In this paper, we are presents different technique through which GOCR (Gujarati Optical Character Recognition) is possible

An Anatomized study on the progress and prospects of CO2 utilization technology

Significant CO2 concentration increases are predicted to contribute greatly to long-term global warming and related climatic instability, resulting in unforeseeable natural disasters, glacier melting, and extreme weather patterns. These difficulties may be solved by successfully collecting CO2 in order to achieve a cost-effective and environmentally sustainable balance between CO2 emissions and utilization. Due to the absence of a current evaluation of state-of-the-art advances in projected carbon utilization methods, it is vital to present an accurate and timely explanation that demonstrates a thorough comprehension of such sophisticated techniques. Given the critical role of carbon consumption in carbon management, it is necessary to analyse the overall picture. To overcome this gap, our study will investigate the benefits of CO2 recycling in a number of industrial processes, including enhanced oil recovery (EOR), fuel and chemical conversion, mineralization, and biological conversion. The objective of this study is to integrate current research in carbon management through analysis of its application in areas and methodologies such as increased petroleum recovery, CO2 conversion to value-added fuels and chemicals, mineralization and biological conversion to value-added products
