Determination of Low-Level sulfur compounds in Natural gas and Petrochemicals by Gas Chromatography and Pulsed flamed photometric Detector

The natural gas and petrochemical industries are just some areas in which the analysis of sulfur containing compounds in process streams is a critical quality control step. Not being able to right away detect and accurately assess or quantify these compounds can lead to contaminated products, damaged equipment, poisoned catalysts and process downtime. This article presents a fast, reliable and robust method for the determination of individual volatile sulfur containing compounds in gaseous fuels by gas chromatography coupled with pulsed flame photometric detection

Insilico Proteome Screening to Identify Prospective Drug Targets in Bacillus anthracis

Various Insilico based genome screening methods helped us in identifying the key drug targets for  a pathogen. The accuracy of the predictions are systematically based on the benchmarks at different stages of methodology and the kind of dataset which is considered for the study. In the current study, we made an effort to screen the entire proteome of Bacillus anthracis for identification of putative drug targets. B. anthracis is the causautive agent for anthrax disease. Instead of genome sequence, the metabolically classified proteome of B. anthracis from JCVI-CMR database was considered for the present study. The entire proteome is been categorized into 25 different metabolisms and in each sub-categorised metabolisms respective protein sequences were retrieved and subjected to screening against Database of Essential Genes (DEG) and Human-Basic Local Alignment Search Tool (H-BLAST) databases. In total 136 essential genes/proteins were obtained from the DEGp (protein) screening whereas 145 Non-Human Homologs (NHHs) were predicted. The identified 145 NHHs are further subjected to criteria based selection to identify the most suitable, functional, putative drug targets. The 8 common hits of both DEG and H-BLAST were considered to be better potential targets as they justify the criteria of being an essential gene/protein, non-human homolog, availability of the 3D structure in PDB and having a significant functional role in the cellular biochemical processes. 

Tribological characteristics of pet track etching membranes after dry friction

The article shows the research of dry friction of PET track membrane according to the pin-on-disk scheme. The results had showed that the friction coefficient increased marginally by increasing the duration of the test. The raise of tests speed more than 5 mm/s contributed to the friction coefficient increasing. The friction coefficient values were comparable in the (1,5 - 5) mm/s range. The load increasing contributed to friction coefficient increasing

The study analyzes the tax revenues arriving from the Tomsk region to different units of the budget system over a 3-year period, moreover, the industry specifics of the region is revealed. Author also pays attention to the problem of tax deduction large share credited to the federal budget that is a consequence of the fiscal policy of the federal center. Moreover, the paper considers the implementation of the planned appointments, the structure, as well as the dynamics of the revenue receipts of the Tomsk region consolidated budget

Enantioselective synthesis of alkenyl aziridine carboxylates and 4-phenylsulfenyl prolines

Chiral cyclic and acyclic allyl aminosulfoxonium ylides have been generated from aminosulfoxonium-substituted gamma,delta-unsaturated alpha-amino acids (method A) and 1-alkenyl aminosulfoxonium salts (method B) upon treatment with DBU. Their application to the asymmetric aziridination of N-tert-butyl-sulfonyl imino ester, generated either in situ (method A) or externally added (method B), gave the corresponding alkenyl aziridine carboxylates with medium to high diastereoselectivity and enantioselectivity. A highly stereoselective Pd(0)-catalyzed isomerization of an E,trans-configured alkenyl aziridine methanol derivative to its E-cis-isomer is described, which proceeded with retention of the double bond configuration. The Michael addition of thiophenol to aminosulfoxonium-substituted gamma,delta-unsaturated alpha-amino acids favours from Re-face. The resulted sulfides were applied to synthesize 4-phenylsulfenyl proline derivatives in overall good yields

Phosphorus Fraction Distribution in Soils of three Rice-Growing Blocks of Mayurbhanj District in Odisha State, India

In the month of June in three distinct blocks of the Mayurbhanj district, the twenty-seven soil samples were collected from nine different rice-growing areas at three depths and analyzed. In accordance to the findings, the soils were found to have low to medium levels of organic carbon and to be moderately acidic to slightly acidic in nature. All the soil samples were under Non-saline condition of Electrical Conductivity and suitable for crops. The study found that soil pH was the main factor influencing different Phosphorus fractions, with Reductant soluble-P being the mostpredominant fraction, followed by Al-P, Fe-P, Ca-P, and Saloid-P. Al-P, Fe-P, and Ca-P were positively correlated with available Phosphorus, indicating their contribution to the soil's available Phosphorus pool. The study also found that Reductant-soluble phosphate (RS-P) was the dominant fraction that fixed and released P from the soil, proving the fixation of Phosphorus by sesquioxide in lateritic soil of Mayurbhanj district in Odisha
