    Abstract Friction surfacing was attempted with aluminum on a mild steel substrate. This paper focuses on the development of empirical relationship for the prediction of coating width, coating thickness of friction surfaced materials. Experimental part of the study is based on five level central composite designs of three process parameters. In order to investigate the effects of input parameters on coating width and coating thickness, an empirical relationship is constructed by multiple regression analysis. Optimization of the model is carried out to study the coating width and thickness using design-expert software. Deposit geometry measurements for all the specimens space carried out and compared with the relative impact of input parameters on coating width and thickness in order to verify the measurement errors on the values of the uncertainty in estimated parameters. The results obtained show that the developed empirical relationship can be applied to estimate the effectiveness of process parameters for a given coating width and thickness.

  5. Article: Molecular evolution of the EGF–CFC protein family

    Abstract The epidermal growth factor-Cripto-1/FRL-1/Cryptic (EGF–CFC) proteins, characterized by the highly conserved EGF and CFC domains, are extracellular membrane associated growth factor-like glycoproteins. These proteins are essential components of the Nodal signaling pathway during early vertebrate embryogenesis. Homologs of the EGF–CFC family have also been implicated in tumorigenesis in humans. Yet, little is known about the mode of molecular evolution in this family. Here we investigate the origin, extent of conservation and evolutionary relationships of EGF–CFC proteins across the metazoa. The results suggest that the first appearance of the EGF–CFC gene occurred in the ancestor of the deuterostomes. Phylogenetic analysis supports the classification of the family into distinct subfamilies that appear to have evolved through lineage-specific duplication and divergence. Site-specific analyses of evolutionary rate shifts between the two major mammalian paralogous subfamilies, Cripto and Cryptic, reveal critical amino acid sites that may account for the observed functional divergence. Furthermore, estimates of functional divergence suggest that rapid change of evolutionary rates at sites located mainly in the CFC domain may contribute towards distinct functional properties of the two paralogs.

    Abstract The adsorptive capability of rice-husk for the sorption of thorium ions from aqueous solutions in batch mode was studied. The key process variables (initial metal ion concentration, initial solution pH and S/L (solid-to-liquid ratio) were optimized for achieving maximum bioremoval efficiency (B%) by employing the Box-Behnken design (33) in response surface methodology (RSM). A quadratic model developed by fitting the experimental data predicted 93% of the responses and estimated the local maximum of B% as >99% for an initial ThIV concentration of 150  g/L, S/L ratio of 5, and an initial pH of 4, and the reported biosorption capacity (qe) is 15.95 mg/g for the same conditions.

    Abstract Genome wide microsatellite maps shall support Phytophthora systematics through the development of reliable markers, enabling species discrimination and variability analyses. Whole genome sequences of 17 Phytophthora accessions belonging to 14 species were retrieved from GenBank and the genome-wide microsatellites in each species were mined. A total of 51,200 microsatellites, including dinucleotide to decanucleotide motifs, have been identified across all the species and each one was characterized for uniqueness and repeat number. The P. infestans T30-4 genome had the highest (6873) and P. multivora 3378 had the lowest number of microsatellites (1802). Dinucleotide motifs (63.6%) followed by trinucleotide motifs (30.1%) were most abundant in all the genome. From 14 species, 250 microsatellites which are unique for the respective genomes are detailed along with their primer combinations and product sizes. P. sojae had the highest number of unique microsatellite motifs. Genome wide microsatellite maps for all the 14 Phytophthora species including the chromosome, position, motif, repeat number, forward and reverse primer sequences and expected PCR product size, for every microsatellite are presented. Markers based on the unique microsatellites could be used to identify each species, whereas the ones common to all species could be used to identify the genetic variability. Furthermore, to confirm the results, pure cultures of P. capsici, P. nicotianae and P. palmivora were procured from the Phytophthora Repository, DNA was isolated and the unique markers were screened across the species. The characteristic markers developed have confirmed the genome analysis results.

    Abstract This study was aimed to design and optimize primaquine phosphate (PQ) loaded nanostructured lipid carriers (NLCs) using response surface methodology. The optimized NLCs were evaluated for various physical and morphological characterizations. The in vitro studies for drug release showed that PQ loaded NLCs had a sustained release up to 72 h and the stability studies confirmed that the PQ-NLCs were stable for 90 d at 4 °C and 25 °C. In vitro erythrocyte toxicity revealed that PQ-NLCs were less toxic than the pure drug. In vitro parasite growth inhibition assay showed an IC
