Comparison of Two Massively Parallel Sequencing Platforms using 83 Single Nucleotide Polymorphisms for Human Identification.

Abstract: The potential of Massively Parallel Sequencing (MPS) technology to vastly expand the capabilities of human identification led to the emergence of different MPS platforms that use forensically relevant genetic markers. Two of the MPS platforms that are currently available are the MiSeq® FGx™ Forensic Genomics System (Illumina) and the HID-Ion Personal Genome Machine (PGM)™ (Thermo Fisher Scientific). These are coupled with the ForenSeq™ DNA Signature Prep kit (Illumina) and the HID-Ion AmpliSeq™ Identity Panel (Thermo Fisher Scientific), respectively. In this study, we compared the genotyping performance of the two MPS systems based on 83 SNP markers that are present in both MPS marker panels. Results show that MiSeq® FGx™ has greater sample-to-sample variation than the HID-Ion PGM™ in terms of read counts for all the 83 SNP markers. Allele coverage ratio (ACR) values show generally balanced heterozygous reads for both platforms. Two and four SNP markers from the MiSeq® FGx™ and HID-Ion PGM™, respectively, have average ACR values lower than the recommended value of 0.67. Comparison of genotype calls showed 99.7% concordance between the two platforms.

Aperture synthesis in phase retrieval using a volume-speckle field

Abstract: The resolution of the reconstructed wave by a phase-retrieval method using a volume-speckle field depends on the aperture defined by the size of the CCD array. The use of a larger aperture is introduced by measuring the speckle field at two different positions in the transverse plane and stitching the measurements together. Improvements in the quality of reconstructions are demonstrated experimentally and by computer simulations. Undesirable effects of camera tilt on the quality of reconstructions from synthetic aperture intensity measurements are experimentally observed and corrected.

Biosorption and desorption studies of chromium(III) by free and immobilised rhizobium (BJVr 12) cells

Abstract: Chromium is a silver-white metal, hard, brittle and rarely found in the free state in nature. The principal source of Cr(III) is the mineral chromite (MgFe)O(Cr, Al, Fe)2O3. Cr and its compounds are widely used in the manufacture of steel, as electroplated coating for corrosion control, mordant in the textile industries and anti-corrosive agents in the tanning industry; and in the manufacture of catalysts, pigments, paints, fungicides and wood preservatives, and in anoding aluminium in the aircraft industry [1]. Hexavalent Cr (CrO 4 −2 , CrO 7 −2 ) are strong oxidising agents.

Consumer preference and properties of raw and cooked milled rice

Abstract: Consumer preference tests for raw and cooked rices were run on representative consumers 16 years and older in a selected Philippine village. For four sets of samples, major criteria for selecting raw milled rice were grain whiteness and hardness, and aroma and flavor for boiled rice. Actual preference ranks suggested partiality to white raw rice and low-amylose, intermediate-amylose and high-amylose boiled rice in order of decreasing preference. Soft texture due to low amylose content probably contributed to better flavor of boiled rice. Selection criteria for one set of waxy rices were aroma and whole, big grains for raw rice, and aroma and cohesiveness for rice cake suman sa antala. Properties disliked in suman were flakiness, and coarse, hard, and soft textures. Among five low-gelatinization temperature, waxy milled rices, the traditional, aromatic, coarse-grained Malagkit Sungsong was preferred over newer rices with less aroma and with longer grains in both raw and suman forms.
