The performance requirements of modern lithium-ion batteries (LIBs) necessitate the use a number scarce and strategically sensitive metals such as lithium cobalt. Recycling end-of-life LIBs reduces demand on primary sources these helps reduce environmental impact LIB waste. Citric acid has proven to be an effective environmentally friendly sustainable lixiviant; however, formation metal citrate...

A matching in a graph G is a set M = {e1, e2, . . . , ek} of edges such that each vertex v ∈ V (G) appears in at most one edge of M . That is, ei ∩ ej = ∅ for all i, j. The size of a matching is the number of edges that appear in the matching. A perfect matching in a graph G is a matching in which every vertex of G appears exactly once, that is, a matching of size exactly n/2. Note that a perfe...

Cat-301 and VC1.1 are monoclonal antibodies that recognize surface-associated molecules on subsets of mammalian CNS neurons. Earlier work demonstrated that Cat-301 recognizes a 680-kDa chondroitin sulfate proteoglycan (PG). VC1.1 has been shown to recognize 3 polypeptide bands on Western blot analysis; a major band at 95-105 kDa and additional bands at 145 kDa and 170 kDa. In the present report...

Amino-functionalized SBA-15 mesoporous silica was prepared, characterized, and used as an adsorbent for heavy metal ions. The organic–inorganic hybrid material was obtained by a grafting procedure using SBA-15 silica with 3-aminopropyl-triethoxysilane and bis(2,4,4-trimethylpentyl) phosphinic acid (Cyanex 272), respectively. The structure and physicochemical properties of the materials were cha...

Seams are very important for the quality of woolen garments. garment must be durable and smooth. Seam performance is an factor determining durability a garment. The tensile characteristics seamed fabric changes with change bias angle, stitch seam types. In this study, three wool fabrics different properties were chosen. Fabrics have been cut in angles 0°, 30°, 45°, 60° 90° then sewn six types (...

Chagas disease is a parasitic pathology that affects millions of people in Latin America, currently being found the territory Peru as serious public health problem. As an objective, study on spatial distribution and cluster analysis 2015-2020 was carried out. The research retrospective descriptive during period 2015-2020. data collection instrument, secondary database notification sheets Minist...

Introduction: Several lunar highland meteorites were found in the Dhofar region of Oman. Here we report the first data on the petrography and mineralogy of four new lunar stones, Dhofar 304, 305, 306 and 307. Dh-304 was found close to Dh-025 and 301, whereas Dh-305, 306 and 307 were recovered nearby Dh-081, 280, 302 and 303. The new meteorites are moderately weathered, impact-melt breccias. No ...
