Recently, Maraj and Nadeem (E. N. Maraj, S. Nadeem, Z. Naturforsch. A 70, 513 (2015)) discussed the application of Rabinowitsch fluid model for the mathematical analysis of peristaltic flow in a curved channel. The mathematical analysis presented by these authors is scrutinised in detail and certain subtle details are pointed out which affect the final results. © 2017 Walter de Gruyter GmbH, Berlin/Boston.

Rule Based Systems belong to a well established branch of Artificial Intelligence. So far thousands of rule based systems and their related systems have been built and successfully used. Recently a Rule Based Engine has been successfully designed and developed using Structured Query Language, and applied in Medical Claim processing domain. The rule engine has been integrated with medical billing software to identify billing errors in medical claims at real-time. Performance of the engine has been good, giving promising results. To further improve the efficiency of the system and to utilize power of rule based systems' techniques, enhancements in the existing rule based engine are being proposed in this research paper. Besides explaining the design of new rule based engine, this paper also reviews the design of current engine, which is already in operation, and the overall architecture of the whole system. Enhanced rule engine being proposed here can be implemented in any domain which involves large number of knowledge oriented checks, and in which frequent modification or updating of these checks is required. This research work proposes a new frame work of rule based systems related to relational database environment (i.e. Structured Query Language), and can have great impact on business world where large amount of data is stored in relational format.

Machine learning is an emerging field of computer science concerned with the learning of knowledge from exploration of already stored data. However, effective utilization of extracted knowledge is an important issue. Extracted knowledge may be best utilized via feeding to knowledge based system. To this end, the work reported in this paper is based on a novel idea to enhance the productivity of the previously developed systems. This paper presents the proposed architecture of a Learning Apprentice System in Medical Billing system being developed for medical claim processing. A new dimension is added whereby, the process of extracting and utilization of knowledge are implemented in relational database environment for improved performance. It opens enormous application areas as most business data is in relational format managed by some relational database management server. The major components of the proposed system include knowledge base, rule engine, knowledge editor, and data mining module. Knowledge base consists of rules, meta rules and logical variables defined in the form of SQL queries stored in relational tables. Rule engine has been successfully developed and deployed in the form of SQL stored procedures. Knowledge editor and data mining modules are under development. Given architecture depicts over all business process of medical billing along with major components of the system. The proposed architecture effectively integrates all three pertinent components given by data mining (production rule discovery), rule based systems technology and database systems environment.

The development of new antimicrobial agents against multidrug resistant pathogens for the treatment of skin infections is of increasing interest. Therefore, the methanol, ethyl acetate chloroform and water extracts from different parts of Sonchus eruca were evaluated for antimicrobial activity against the most frequent skin pathogens. It was found that most plant extracts studied had antibacterial and antifungal activities. The antibacterial activities with the highest zone of inhibition 19 and 18 mm were significantly produced by the leaves extracts of Sonchus eruca against Klebsella. All other extracts of root, stem and leaves also showed significant results. Phytochemical anaylsis of Sonchus eruca confirmed the presence of Flavonoids, Saponins, Antraquinone, Terpenoids, Tannins, Reducing Sugar and Cardiac glycosides. Antimicrobial activities may be due to the flavoniods.

In the present study, the antioxidant potential of different crude extracts of Sonchus eruca, was evaluated. The extracts were investigated for its antioxidant activity using 2, 2-diphenyl-1-picryal-hydrazyl (DPPH) method. The crude fractions evaluated were n-hexane, chloroform, ethyl actate and water. The ethyl acetate extracts from S.eruca at 500μg/mL exhibited highest 79.11% DPPH activity fallowed by chloroform showing 67.19%. The other extracts of plants also showed significant antioxidant activity.

In order to identify and compare the effects of different concentrations of coatings (Carboxy Methyl Cellulose, CaCl2, Bee wax) and packaging (polyethylene sheet), on improving the keeping quality of mangoes its storage performance was evaluated. Mangoes after harvesting were given hot water treatment at 50±2°C for three minutes as quarantine measure against fungal attack. Then fruits were coated with three different concentrations of CMC and CaCl2 along with bee wax coating and polyethylene sheet packaging. All the treatments were applied in combination with KMnO4 soaked with sponge cubes used as ethylene absorbents. Fruits were kept at refrigerated temperature for 80 days and evaluated for physico-chemical and sensory changes at an interval of seven days. All coatings delayed fruit ripening and improved the keeping quality of the produce but best results were exhibited by Carboxy Methyl Cellulose (CMC) at 2% level. It extended storage life up to 77 days with appreciable retention of all the quality parameters. © Asian Network for Scientific Information, 2011.
