The research work aims to develop a bioanalytical method using liquid chromatography and validated for the determination of canagliflozin by using an internal standard. Department of Pharmaceutical Chemistry, Smt. Kishoritai Bhoyar College of Pharmacy, New Kamptee, Nagpur (MS). Isocratic chromatography separation was achieved on an LC system with PDA detector on an ACE C18 (150mm× 4.6mm × 5µm) column using a mobile phase composition of acetonitrile: ammonium acetate buffer in the ration of 50:50 v/v (pH 4.5), orthophosphoric acid is used to adjust pH of mobile phase and the flow rate at 1.0ml/ min. and estimation was carried out at 291 nm. The retention time of a drug was 4.633 minutes. The method was validated for several parameters (specificity, linearity, precision, and accuracy) and also successfully applied for the pharmacokinetic in female rats. Calibration plot was linear (r2 > 0.9973) over the concentration range of 5-30 µg/ml for canagliflozin. The high recovery and low relative standard deviation (%RSD) confirm the suitability of the method. The result of Limit of Detection (LOD) and Limit of Quantitation (LOQ) were found to be 0.1099 μg/ml and 0.3331 μg/ml, respectively. The new RP-HPLC method can be conveniently adapted for examining canagliflozin concentration in rat plasma after oral administration.

To generate realistic test data is a challenging for software testers. Realistic test data generation for certain input type is hard to automate and therefore laborious. So in this paper, string inputs will be used from the internet by performing web queries based on the key identifiers appearing in the source code of the program under test. The resultant URLs will be generated, tokenised and the collected regular expressions are matched with the text and get valid string values.

Normal cash has developed and appears numerous downsides such as inaccessibility. It is inclined to burglary and is intensely directed by government offices. Cryptocurrencies have risen as a egotistic money related framework. They depend upon secure disseminated ledger data structure. Mining plays a critical portion in this framework [1]. Basically, our cryptocurrency could be a conveyed database that keeps up tamper-proof information structure pieces containing his bunches of person exchanges. Blockchain innovation can be a widely emerging approach to data innovations. Bitcoin as a cryptocurrency has made several considerations since it was one of its earliest implementations. They discuss the key elements driving the development of sophisticated cryptocurrencies alongside Ethereum, a blockchain implementation with a focus on informed contracts [1]. In its most basic form, our cryptocurrency may be thought of as a distributed database that keeps track of tamper-proof data structure blocks comprising batchesof individual transactions [1].
