The Neoproterozoic Bhander Group in the Son Valley, central India conformably overlying the Rewa Group, is the uppermost subdivision of the Vindhyan Supergroup dominantly composed of arenites, carbonates and shales. In Maihar-Nagod area, a thick pile of unmetamorphosed clastic sedimentary rocks of Bhander Group is exposed, which provides a unique opportunity to study Neoproterozoic basin development through provenance and tectonic interpretations. The provenance discrimination and tectonic setting interpretations are based on modal analysis and whole rock geochemistry. The average framework composition of the detrital sediments composed of quartz and sedimentary lithic fragments are classified as quartz arenite to sublitharenite. The sandstone geochemically reflects high SiO 2 , moderate Al 2 O 3 and low CaO and Na 2 O type arenite. The high concentration of HFSE such as Zr, Hf, and Th/Sc, Th/U ratios in these sandstones indicate a mixed provenance. The chondrite normalized REE pattern shows moderate to strong negative Eu anomaly which suggests that major part of the sediments were derived from the granitic source area. The sandstone tectonic discrimination diagrams and various geochemical plots suggest that the provenance of the lower and upper Bhander sandstone formations was continental interior to recycled orogen.

The notion of S-metric space was introduced by Sedghi et al. In this paper we study the ideas of I and I * -Cauchy sequences in S-metric spaces and investigate their relation following the same approach as done by Das and Ghosal. We then study the ideas of I and I * -divergent sequences in S-metric spaces and examine their relation under certain general assumption.

In this paper we have studied the idea of ideal completeness of function spaces Y X with respect to pointwise uniformity and uniformity of uniform convergence. Further involving topological structure on X we have obtained relationships between the uniformity of uniform convergence on compacta on Y X and uniformity of uniform convergence on Y X in terms of I-Cauchy condition and I-convergence of a net. Also using the notion of a k-space we have given a sufficient condition for C(X, Y ) to be ideal complete with respect to the uniformity of uniform convergence on compacta.

Polyhydroxyalkanoates (PHAs) are a family of linear biodegradable thermoplastic polyesters that are synthesized in nature by bacterial fermentation. Their formation is triggered by a deficiency of nutrients and an excess supply of carbon sources. Despite the high yield of PHAs via bacterial fermentation, it is not an economically viable route. To reduce the cost, photoautotrophic production is thought to be a desired route. Cyanobacteria are one of the only prokaryotic species that naturally produces PHAs (under stress conditions) by photosynthesis. The current study describes the mixotrophic biosynthesis of poly(3-hydroxybutyrate) (PHB) in cyanobacteria (blue green algae) Nostoc muscorum followed by polymer extraction. The extracted polymers (in the fiber/yarn form) may have uses in various textile-related medical applications such as tissue scaffolds, sutures threads, and surgical meshes.

Proso millet (Panicum miliaceum) is an economically important crop in the United States for low-end uses such as birdseed and livestock feed. The current study is directed at using starch extracted from proso millet for higher value-added applications, such as a thickener in textile printing. The paper describes a method of extracting starch from proso millet followed by physiochemical characterization of the extracted starch using standard methods. Characterized starch was incorporated as a thickener in a vat dye print formulation and printed on a 100% cotton fabric. Results showed starch from proso millet possessed desirable thickener properties such as excellent paste clarity, viscosity, solubility, shear stability, and crystallinity. Proso starch printed fabric demonstrated good color value, flexibility, crockfastness, and washfastness.
