Three simple, accurate and economical methods have been developed for the estimation of norfloxacin and ornidazole in tablet dosage form. First method is based on the simultaneous equations, wavelengths selected for analysis were 273.0 nm (λmax of norfloxacin) and 318.5 nm (λmax of ornidazole), respectively, in 0.1N NaOH. Second method is Q-analysis method, based on absorbance ratio at two selected wavelengths 297.0 nm (iso-absorptive point) and 318.5 nm (λmax of ornidazole). Third method is first order derivative spectroscopy using 297.5 nm (zero cross for norfloxacin) and 264.0 nm (zero cross for ornidazole). The linearity was obtained in the concentration range of 4-20 μg/ml and 5-25 μg/ml for norfloxacin and ornidazole, respectively. The results of the analysis have been validated statistically and by recovery studies.

Cloud computing gives an adaptable and helpful route for information sharing, which brings different advantages for both the general public and people. However, there exists a characteristic resistance for clients to straightforwardly outsource the mutual information to the cloud server since the information frequently contain significant data. In this manner, it is important to put cryptographically upgraded get to control on the mutual information. Personality based encryption is a promising cryptographical primitive to manufacture a pragmatic information sharing framework. Be that as it may, get to control is not static. That is, the point at which some client's approval is lapsed, there ought to be a component that can evacuate him/her from the system. Thusly, the disavowed client can't get to both the beforehand and along these lines shared information. To this end, we propose an idea called revocable-capacity character based encryption (RS-IBE), which can give the forward/in reverse security of ciphertext by presenting the functionalities of client disavowal and ciphertext redesign at the same time. Moreover, we display a solid development of RS-IBE, and demonstrate its security in the characterized security show. The execution examinations demonstrate that the proposed RS-IBE scheme has points of interest as far as usefulness and proficiency, and in this manner is achievable for a reasonable and savvy information sharing framework. At last, we give usage aftereffects of the proposed plan to exhibit its practicability.

Objective: Todevelop a new high-performance thin-layer chromatography (HPTLC) method for the quantification of berberine in herbal extract and pharmaceutical dosage form. Materials and Methods: The HPTLC was performed on aluminium foil plates coated with 200 µm silica gel 60F₂₅₄. Linear ascending development with toluene:ethyl acetate:formic acid:methanol 9:9:3:1 (v/v/v/v) was performed at room temperature (25 ± 2°C) in a twin-trough glass chamber saturated with mobile-phase vapour. Compact bands (R_F 0.58 ± 0.02) were obtained for berberine. Spectrodensitometric scanning was performed in fluorescence mode at 350 nm. The method was validated for precision, recovery, robustness, specificity, and detection and quantification limits, in accordance with International Conference on Harmonization guidelines. Results: Linear regression analysis of the calibration plots showed a good linear relationship (r² = 0.9996 ± 0.0001) between peak area and concentration in the range 10–100 ng/band, respectively. The limits of detection and quantification were 2.8 and 9.3 ng/band. The recovery of the method was 98.5–100.6%. Conclusion: The above method was a rapid and cost-effective quality-control tool for routine analysis of berberine in herbal extracts and in pharmaceutical dosage form.

In recent years there has been ascension in cloud computing and social networking technologies. Cloud computing shifts the computing resources to a 3rd party, eliminating the requirement to buy, set up and maintain those resources. With the inducement of down operational prices in code, hardware and human effort, several firms area unit considering the utilization of cloud services. Likewise, social networks have seen huge growth, with innumerable web users actively collaborating across varied social networking websites. Even firms have begun victimization social networks as a method to promote and reach their customers. This paper can survey the present problems in cloud computing and social networks and the way these technologies area unit getting used along.
