Experimental Set Up of Optical Tomography Probe and Visualization of Characteristics of a Taylor Bubble
Abstract: Abstract Conventional methods for the detection of bubbles uses probes which physically protrude into the flow field and thus may affect the flow dynamics, thereby tethering the formation, development and flow of bubbles. In thermal power plant, it is rather difficult to physically see which type of two phase flow is happening in the pipe. In such a case, an optical tomography sees its application. Depending upon the type of …

Introduction of New Flow Resistance Parameter for the Study Coefficients of Vertical Velocity Distribution
Abstract: Validity of log-law distribution of velocity in vertical section for alluvial channel under different localized bed and flow conditions is studied in this paper. In this study a new dimensionless parameter, Hari’s Number (Ph), whose value is to be taken as Q/νh, is proposed to relate the same with numerical coefficients of log-law distribution. It was found that the values of numerical coefficients could satisfactorily be correlated to the proposed …

Genetic Diversity and Characterization of Ocimum sanctum Collected from Anand, Central Gujarat Region, by PCR-based RAPD Markers
Abstract: Genetic relationships were examined among thirty germplasm accessions belonging to ten Ocimum species using RAPD markers. A very high degree of polymorphism (98.92%) was observed. UPGMA cluster analysis of genetic similarity indices grouped all the accessions into two major clusters corresponding to previously reported botanical sections. Intra-clustering within the two clusters precisely grouped the accessions belonging to one species in onesub-cluster as expected from their genetic background. Results of this …

Assessment of the effectiveness of PMTCT (Prevention of Mother to Child Transmission) to Children Born from HIV-1 positive Mothers
Abstract: Mother-to child transmission (MTCT) of HIV is one of the biggest challenges of the HIV/AIDS pandemic especially in resource constrained settings. Africa has the highest burden of the disease accounting for about 90% of pediatric HIV infections. Approximately 370,000 children became infected with HIV globally; most of these infections occurred through mother-to-child transmission. PMTCT (prevention of mother to child transmission) service reduces the risk of this transmission. In the absence …
