Osmotic coefficients measured by vapor pressure osmometry are reported for aqueous polyethylene-glycol (PEG-400, PEG-1000, and PEG-4000) solutions. The derived properties such as activity and activity coefficients have been studied as a function of solute concentration. These data along with the partial molar volume data have been analyzed with the help of molecular theories such as Flory-Huggins, McMillan-Mayer, and Kirkwood-Buff. The application of these theories enabled us to obtain second virial coefficients of PEG's, the number of binding sites, χ12 (Flory-Huggins interaction parameter), and the Kirkwood-Buff (KB) integrals, defined by the equation: Gij = ∫ 0. © 2013 Elsevier B.V.

Here we reported the synthesis of MgCuZn ferrite (Mg0.48Cu 0.12Zn0.40Fe2O4) by ceramic and self-sustaining auto-combustion (sucrose) methods. Required oxides in powder form were processed (hand mill=3 h, pre-sinter=600 °C for 180 min and final sinter=910 °C for 9 h) to obtain the ferrite sample through the ceramic methods. Whereas, aqueous metal nitrates along with the sucrose as fuel were processed (at 200 °C, final sinter=600 °C for 180 min) to obtain ferrite product via the auto-combustion route. As-synthesized ferrite samples were then subjected to crystallographic, structural and magnetic investigations by techniques viz. X-ray diffraction, IR spectroscopy and B-H measurements. Purity and phase formation were confirmed by XRD examinations. Cation redistribution was also suggested by XRD analyses which supplement the variation of magnetic properties. IR absorption bands were found to be in the expected high frequency range (574.95 cm-1 and 582.39 cm-1) and low frequency range (≈431 cm-1) which fortifies the spinel phase formation. Boost in magnetic performance of sucrose methods' yield was observed owing to reduced porosity and increased surface area. Thus, MgCuZn ferrite prepared via the self-sustaining auto-combustion route has superior magnetic properties at relatively low sintering temperature and can be employed in multi-layer chip application readily. © 2012 Elsevier Ltd and Techna Group S.r.l.

In all, 200 antifungal Bacillus spp. (AFB) were isolated from aerial surfaces of pomegranate plant and 50 inhibited the growth of major fruit rot pathogens viz., Phomopsis varsoniana, Aspergillus flavus, A. clavatus, Beltraniella humicola, Fusarium graminearum and Rhizopus stolonifer. The AFB isolates exhibited maximum antifungal activity at pH 7 to 9 at 30°C and 40°C in malt extract broth. The most potent isolate AFB22 was identified as B. subtilis by 16S rDNA sequencing. Crude antifungal compound was recovered from isolate, after 80% saturation by ammonium sulphate, dialysis and freeze drying, was heat stable but sensitive to proteolytic enzymes and low pH. This isolate also demonstrated plant growth promoting traits like phosphate solubilization and production of indole acetic acid, siderophore and chitinase. Cells and cell free supernatant (CFS) of the AFB22 prevented rotting in pomegranates when challenged with spores of P. varsoniana. According to Kaplan-Meier procedure of survival analysis and Tarone-Ware statistics test, the incidence of rot was significantly lower (P < 0.05) in pomegranates treated with cells and CFS, when compared with fruits inoculated with pathogen only. Mean survival time of pomegranates was 6.74, 6.68 and 4.33 days in treatments of cells, CFS and fungal pathogen, respectively. This study demonstrates the bio-protection of pomegranates by B. subtilis AFB22 from the fungal fruit rot pathogens, an alternative to synthetic fungicides. Source

Globalization and technical revolution are raising several challenges to the software development sector. Over the past 50 years, software has evolved as a specialized problem-solving and information analysis tool to an industry, but now it is facing multiple challenges. The objective of this study is to landscape current knowledge, in terms of productivity and find out its impact on the software development. To resolve such problems, “Software Development Practitioner” needs to find out a flexible way (Jugaad) for development. “Jugaad” is the Indian common man’s philosophy to achieve the dream goal within the available resources. The researcher has made earnest attempts to study the steps to be undertaken to make the flexible module. The goal of this paper is to rectify the present hurdles and hassles in development approaches by representing “Selection of Software Development Methodologies Advisory System” on the basis of reference of fuzzy expert system. © Springer India 2016.

Diagnosis according to Ayurveda is to find the root cause of a disease. Out of the eight different kinds of examinations Nadi-Pariksha (pulse examination) is important. Nadi-pariksha is done at the root of the thumb by examining the radial artery using three fingers. The features associated with the pulse pressure signals are important from diagnostic point of view. Ancient Ayurveda identifies the health status by observing the wrist pulses in terms of 'Vata', 'Pitta' and 'Kapha', collectively called as tridosha, as the basic elements of human body and in their combinations. © 2012 IEEE.
