GC-FID and HPLC-DAD were developed for determination of menadione (MN) and menadione sodium bisulphite (MSB). By means of each method, quantitative analysis of MSB in commercial pharmaceutical was performed in both direct analysis of MSB and analysis of MN by converting MSB to MN with sodium carbonate. GC-FID method was carried out on the HP-5 capillary column using nitrogen gas. HPLC-DAD metho...

The SHA-256 hash function has started getting attention recently by the cryptanalysis community due to the various weaknesses found in its predecessors such as MD4, MD5, SHA-0 and SHA-1. We make two contributions in this work. First we describe message modification techniques and use them to obtain an algorithm to generate message pairs which collide for the actual SHA-256 reduced to 18 steps. ...

We present a combined theoretical and experimental study of the ferromagnetic semiconductor (Ga,Mn)As which explains the remarkably large changes observed on low-temperature annealing. Careful control of the annealing conditions allows us to obtain samples with ferromagnetic transition temperatures up to 159 K. Ab initio calculations, in situ Auger spectroscopy, and resistivity measurements dur...

Intel recently documented its AVX2 instruction set extension that introduces support for 256-bit wide single-instruction multiple-data (SIMD) integer arithmetic over double (32-bit) and quad (64-bit) words. This will enable Intel’s future processors—starting with the Haswell architecture, to be released in 2013—to fully support 4-way SIMD com­ putation of 64-bit ARX algorithms (32-bit is alread...

To meet the demands of emerging electrification technologies, polymers that are capable withstanding high electric fields at temperatures needed. Given staggeringly large search space polymers, traditional, intuition- and experience-based Edisonian approaches too slow discovering new can these demands. In this work, a genetic algorithm was combined with five machine learning-based property pred...

background: the purpose of this paper is to establish an easy and reliable biodosimeter protocol to evaluate the biological effects of proton beams. materials and methods: human peripheral blood lymphocytes were irradiated using proton beams (let: 34.6 kev μm−1), and the chromosome aberrations induced were analyzed using cytokinesis-blocked (cb) micronucleus (mn) assay. to determine the efficie...

In order to study the effect of different levels of the manure and foliar application of Zn and Mn fertilizers on the quantitative and qualitative yield of soybeans (var. Williams), a factorial experiment was conducted in a randomized complete block design with three replications in 2012. Treatments involved three levels of fertilizer: manure (zero as control; six and 12 t/ha), two lev...
