Solvent Extraction Separation Study of Fe(III) from Sulphate Medium by CYANEX 272 in kerosene

The extraction of Fe(III) with Bis(2,4,4-trimethylpentyl) phosphinic acid, commonly known as CYANEX 272, in kerosene from aqueous sulphate medium was investigated. The extraction was found to increase with extractant and Fe(III) concentration while it decreases with hydrogen ion and sulphate concentration in the aqueous phase. The stoichiometry of the extracted metal species was found to be Fe(HSO4)A2.2(H2A2). The equilibrium constant and thermodynamic functions of Fe(III) extraction were calculated. Stripping investigations indicated that H2SO4 of concentration (0.5-5 M) is effective for stripping Fe(III). The experimental obtained capacity of CYANEX 272 was found to be 0. 2 M Fe(III) per mole extractant after four stages. Results of the effect of temperature indicate that the Fe(III) extraction in the investigated system is endothermic.
Ontology Reusing: A Review

Building ontologies from scratch is a process that requires many resources as time, knowledge about the domain, among others. Sometimes ontologies are developed in the same domain with similar designs and the same propose causing a repetitive work. Ontology reusing allows us to build models with lower resources. There are several techniques for ontology reusing as: mapping, alignment, fusion, ontology integration, ontology networks, among others. In this paper, we analyze three techniques oriented to ontology reusing from the use of entire ontologies (no modularization).
An MINLP process synthesizer for a sequential modular simulator

This paper deals with the development of a mixed integer nonlinear programming (MINLP) synthesizer for sequential modular simulators. Firstly, a variant of the outer approximation/equality relaxation/augmented penalty (OA/ER/AP) algorithm for MINLP problems is presented that makes use of Benders cuts in previous or subsequent iterations. An automatic process synthesis environment is then described for the public version of the ASPEN simulator using this algorithm, with the decomposition strategy by Kocis and Grossmann. The application of this new capability is demonstrated with several examples including the structural optimization of the hydrodealkylation of toluene process.

A Validated UV Spectrophotometric Method for the Estimation of Olopatadine and Ketorolac Tromethamine in Ophthalmic Dosage Form

To develop simple and economical UV spectrophotometric method for the estimation of Olopatadine and Ketorolac tromethamine in the combined ophthalmic dosage form available in the market for conjunctivitis. Two drugs Olopatadine and Ketorolac tromethamine are present in the ratio of 4:1. The two drugs were simultaneously estimated by first order derivative. From the overlain first order derivative spectra wavelength 340nm (ZCP for Olopatadine) and 229nm (ZCP for Ketorolac) were selected for the quantification of Olopatadine and Ketorolac. The method was validated as per the ICH guidelines and the results were statistically validated. Linearity was observed in concentration range of 8.2-45µg/ml for Olopatadine and 2.5-50µg/ml for Ketorolac. The accuracy of the method was evaluated by recovery studies and good recovery results were obtained between 98% to 100% and the relative standard deviation was found to be below 2% . A simple, accurate, sensitive and economical UV-spectrophotometric method for the estimation of Olopatadine and Ketorolac in combined dosage form has been developed which can be employed in the industry for the routine analysis.
Synthesis of cross-linked amides and esters as thin film composite membrane materials yields permeable and selective material for water vapor/gas separation

In this work, 3,5-diaminobenzoic acid (BA) was selected to synthesize polyamide as a selective layer because it is considered desirable to fabricate hydrophilic thin film composite (TFC) membranes for water vapor separation. Cross-linked chains of TFC membranes by interfacial polymerization were suggested, confirmed and discussed by using the compiled results of characterization, such as ATR-FTIR, XPS, FE-SEM, BET surface area, TGA and water contact angle. As a result, the BA-1-10 membrane (1.0 wt% of BA, 0.2 wt% of TMC and 10 min of reaction time) showed the best permeance and separation factor as 2160 GPU and 23, respectively, compared with other TFC membranes prepared under different conditions. It was shown that with a higher concentration of BA containing carboxylic acid a faster diffusion, greater reactivity and the formation of hydrophobic esters are possible. Moreover, the acyl chloride group (–COCl) of TMC was hydrolyzed to COOH and improved the hydrophilicity for a better sorption of water vapor. However, the hydrophobic esters were generated on a selective layer due to the excessive reaction time over 10 min. It was found that the reaction time should be the same as the immersion time of the aqueous monomer to give adequate high performances.

Simultaneous determination of organic acids in wine samples by capillary electrophoresis and uv detection: optimization with five different background electrolytes

A simple technique is described for the routine capillary electrophoretic determination of organic acids in wine samples. Several aromatic and non-aromatic compounds, including phthalic acid, benzoic acid, sorbic acid, boric acid, and phosphate, were evaluated as background electrolytes in order to obtain the highest resolution and detection sensivity. Factors that affect capillary electrophoretic separation such as the concentration and pH of the background electrolyte (BGE), the concentration of the electroosmotic flow modifier (EOF), and methanol addition to the electrolyte were investigated systematically. Tartaric, malic, succinic, acetic, and lactic acids were determined simultaneously in approximately six minutes using an electrolyte containing 3 mM phosphate and 0.5 mM myristyltrimethylammonium bromide (MTAB) as electroosmotic flow modifier at pH 6.5. This method is quantitative, with recoveries in the 90-102% range and linear up to 50 mg L -1 . The precision is better than 1% and the procedure shows the appropriate sensibility, with detection limits between 0.015 and 0.054 mg L -1 . The proposed method was successfully employed for the determination of organic acids in wine samples by direct sample injection after appropriate dilution and filtration.
Eriodictyol attenuates spinal cord injury by activating Nrf2/HO-1 pathway and inhibiting NF-κB pathway

Purpose: To investigate the effect of eriodictyol on spinal cord injury (SCI) and its underlying mechanism of action.Methods: Thirty Sprague-Dawley rats were assigned to sham, SCI, and eriodictyol-treated groups (SCI + Eri; 10, 20, and 50 mg/kg). Moderate spinal cord contusion injury was induced to model SCI. Locomotor recovery was assessed based on Basso, Beattie, and Bresnahan (BBB) score. Pain wasevaluated by paw withdrawal threshold (PWT) and latency (PWL), and spinal cord water content was measured. Tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and interleukin-6 (IL-6) expression were determined by enzyme-linked immunosorbent assay (ELISA) and reverse transcriptase quantitative polymerase chain reaction (RT-qPCR). Immunoassay was used to determine malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), and glutathione peroxidase (GSH-PX) levels while Western blotting was employed to evaluate nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), nuclear factor-kappa B (NF-κB), and phosphorylated NF-κB (p-NF-κB) levels.Results: Eriodictyol elevated BBB score, PWT, and PWL in SCI rats but reduced spinal cord water content (p < 0.05). Eriodictyol treatment down-regulated TNF-α, IL-1β, IL-6, and MDA, whereas SOD, GSH, and GSH-PX levels were elevated (p < 0.05). Eriodictyol administration increased Nrf2 and HO-1 levels but reduced p-NF-κB/NF-κB. Conclusion: This study provides a potential therapy to promote long-term functional recovery following SCI. Keywords: Spinal cord injury, Eriodictyol, Nrf2/HO-1 pathway, NF-κB signaling pathway, Polymerase chain reaction, Basso, Beattie and Bresnahan score
Performance analysis of axial‐flow mixing impellers

Theoretical formulations for impeller performance were evaluated based on a blade-element theory. These enable the calculation of the head and power vs. flow-rate curves of axial-flow impellers. The technique uses the lift and drag coefficients of the blade section of an impeller to calculate the spanwise swirl-velocity distribution. Using the angular-momentum equation, it is possible to calculate the corresponding spanwise distribution of the energy head of the impeller. Integration of these distributions of head and torque gives the impeller's performance. Parameters including the flow number, the power number, the thrust force number, and the swirl velocity can be found at the impeller operating point, determined using the head curve and an experimentally calibrated resistance curve. A laser Doppler velocimetry (LDV) system was used to measure the velocity distribution for different axial flow impellers in mixing tanks. Calculated flow and power numbers agreed well with the experimental results. Using the blade's spanwise head distribution and a set of calibrated flow-resistance data, it is also possible to estimate an impeller's outlet axial-velocity distribution. Predictions compared well with LDV experimental data. The effect of impeller-blade angle, number of blades, blade camber, and blade thickness on the performance of axial-flow impellers was investigated using the Agitator software.
Geological Characteristics of Close Geographical Related Vineyards Influence Microbiomes of Two Soil Depth Profiles With Potential Impacts on Wine Quality

Background The role of soil microbiomes in agriculture is now becoming more and more important, leading to definition of plants as complex organisms formed by the plant itself plus the microbes inhabiting its tissues, the surface of every organ and the ones living adhered or in proximity of the roots. In this context it is important to define the factors able to influence the composition of such microbial communities. In addition, as already demonstrated, the microbial community associated to a specific soil is able to predetermine the health status of the crops in the future. For this reason, we decided to investigate how the soil geological characteristics can influence the microbial community associated to the close geographical related vineyard.Results We decided to analyse a calcarenitic and a marly-limestone soil which are both typical of the viticulture in the Menfi area (Sicily, Italy). Moreover, since vineyard is a semi-anthropic environment we decided to investigate both the top (10-20 cm) and deep (120 cm) soil layers as anthropic influenced and almost-undisturbed soil respectively. Interestingly we observed that, despite the close geographical proximity, the soil microbiomes were slightly different and that in addition, the soil geological characteristics are able to influence the root distribution and the accumulation of both pathogen- and symbiont-related genera. Furthermore, sensory profiles of the Grillo wines obtained from the two different soils confirmed the tight link between soil origin and wine traits.Conclusions In contrast to what observed in other works we pointed out that the geological characteristics of soils can have an important influence on soil microbial composition and assemblage in close geographical related vineyards, with a potential effect on wine features. Furthermore, defining the microbial composition of agricultural soils it’s a crucial step to achieve a more sustainable agriculture and viticulture. In this optic, the observed link between the geological characteristics and the microbiome profiles need to be taken into account when considering a soil for the successful establishment low chemical input agriculture practices.The SRA accession numbers of the NGS reported in this paper are deposited in NCBI under the BioProject PRJNA655455; BioSample SAMN15735114 and SAMN15735115; SRA accession SRR12436974 and SRR12436973
Tight junctions and their regulation by non-coding RNAs

Tight junction (TJ) is a “zippering up” junction structure located at the uppermost portion of adjacent epithelial/endothelial cells in organs and tissues. TJs maintain the relative stability of intracellular substances and functions by closing or opening intercellular pathways, coordinating the entry and exit of molecules of different sizes and charges, and regulating the permeability of paracellular barrier. TJs also prevent microbial invasion, maintain epithelial/endothelial cell polarity, and regulate cell proliferation. TJs are widely present in the skin and mucosal epithelial barriers, intestinal epithelial barrier, glomerular filtration barrier, bladder epithelial barrier, blood-brain barrier, brain-blood tumor barrier, and blood-testis barrier. TJ dysfunction in different organs can lead to a variety of diseases. In addition to signal pathways, transcription factors, DNA methylation, histone modification, TJ proteins can also be regulated by a variety of non-coding RNAs, such as micro-RNAs, long-noncoding RNAs, and circular RNAs, directly or indirectly. This review summarizes the structure of TJs and introduces the functions and regulatory mechanisms of TJs in different organs and tissues. The roles and mechanisms of non-coding RNAs in the regulation of TJs are also highlighted in this review.
Calorimetric Studies of the Crystallization Growth Process in Glassy Se70Te30-xAgx Alloys

Dierential Scanning Calorimetry (DSC) is performed at dierent heating rates under non-isothermal conditions to study the crystallization kinetics of Se:70Te:26Ag:04 and Se:70Te:24Ag:06 chalcogenide glasses in terms of the activation energy of nucleation and growth process. To understand the nucleation and growth process, the values of the growth morphology parameter n and the numerical factor m of crystallization mechanism have been evaluated using dierent non{isothermal methods. The values of n and m have been found to be nearly equal, indicating that the present glasses have sucient nuclei before DSC experiment and the activation energy for nucleation process EN is zero. Hence, the eective activation energy for overall crystallization Ec is equal to the activation energy for growth process EG.
Dual antiplatelet therapy in patients with coronary artery disease after percutaneous coronary intervention with drug-eluting stents: A systematic review and network meta-analysis

Background: This network meta-analysis was committed to evaluating the efficacy and safety of different dual antiplatelet therapies (DAPTs) after percutaneous coronary intervention (PCI) with drug-eluting stents (DESs). Methods: Randomized controlled trials (RCTs) comparing two of the following DAPT strategies: long-term (>12 months) DAPT (L-DAPT), 12-months DAPT (DAPT 12Mo), short-term (≤6 months) DAPT followed by aspirin monotherapy (S-DAPT+ASA), short-term DAPT followed by a P2Y12 receptor inhibitor monotherapy (S-DAPT+P2Y12) were searched. Primary outcomes were all-cause mortality, cardiac death, myocardial infarction (MI), stroke, major bleeding, any bleeding, definite or probable stent thrombosis (ST). This Bayesian network meta-analysis was performed with the random-effects model.Results: Twenty-four RCTs (n=81,376) were included. L-DAPT increased the risk of major bleeding (OR 2.37, 95%CI 1.32-5.03 compared with S-DAPT+P2Y12) and any bleeding (OR 2.95, 95%CI 1.91-4.34 compared with S-DAPT+P2Y12). When compared with L-DAPT, DAPT 12Mo (OR 1.54, 95%CI 1.13-2.02) and DAPT+ASA (OR 1.67, 95%CI 1.22-2.19) were associated with higher rates of MI, but S-DAPT+P2Y12 obtained no statistical difference. The sensitivity analysis revealed that the risks of major bleeding and any bleeding further increased for ≥18 months of DAPT. In the subgroup analysis, short-term DAPT (S-DAPT) presented similar efficacy and safety to DAPT 12Mo for patients with the acute coronary syndrome (ACS), and lower risks of major bleeding and all-cause mortality were observed in S-DAPT+P2Y12 among patients with newer-generation DES.Conclusions: S-DAPT+P2Y12 presented superiority in patients with all clinical presentations, for a lower risk of bleeding and not associated with increased ischemic harm. Besides, prospective research between aspirin monotherapy and P2Y12 monotherapy was required.
Revealing the biodiversity of Chilean birds through the COI barcode approach

Abstract The mitochondrial cytochrome c oxidase subunit I (COI) gene is an effective molecular tool for the estimation of genetic variation and the identification of bird species. This molecular marker is used to differentiate among Chilean bird species by analyzing barcodes for 76 species (197 individuals), comprising 28 species with no previous barcode data and 48 species with sequences retrieved from the BOLD and GenBank databases. The DNA barcodes correctly identified 94.7% of the species analyzed (72 of 76 species). Mean intraspecific K2P distance was 0.3% (range 0–8.7%). Within the intraspecific divergence range, three species, Phrygilus gayi, Sephanoides sephanoides and Curaeus curaeus, showed relatively high intraspecific divergence (1.5–8.7%), possibly due to the presence of a species complex or geographic isolation of sub-populations. Mean interspecific K2P distance was 24.7% (range 1.3–43.5%). Consequently, the intraspecific K2P distance showed limited overlap with interspecific K2P distance. The mean intraspecific divergence in our study was similar to that found in temperate regions of South America (0.24%). However, it was approximately one order of magnitude lower than values reported for bird species in tropical regions of northern South America (1.8–2.13%). This result suggests that bird species from Chile show low levels of genetic structure and divergence. The small overlap between intra- and inter-specific distances implies that COI barcodes could be used as an effective tool to identify nearly all the Chilean bird species analyzed.

The long-run effects of streamed primary education on socio-political participation PRELIMINARY DRAFT PLEASE, DO NOT QUOTE!

Until ‘60s British primary school widely applied streaming, i.e. the practice of assigning pupils to classes on the basis of an overall assessment of their general ability. This paper investigates the lasting impact of attending streamed primary school on socio-political participation during adulthood. By using NCDS data and 2SLS models to account for endogeneity, first, we find that cohort-members enrolled in primary school adopting streaming, would be less likely involved in socio-political activities during adulthood. Second, by focusing on sub-sample of cohort-members enrolled in streamed primary school, we find that those assigned to high-ability classes would be more likely involved in adult socio-political activities than those assigned to low-ability classes. In sum, our findings suggest that school organization would be relevant when shaping social behavior and social capital formation.
The PhenObs initiative: A standardised protocol for monitoring phenological responses to climate change using herbaceous plant species in botanical gardens

1. Changes in phenology induced by climate change occur across the globe with important implications for ecosystem functioning and services, species performance and trophic interactions. Much of the work on phenology, especially leaf out and flowering, has been conducted on woody plant species. Less is known about the responses in phenology of herbaceous species induced by global change even though they represent a large and important part of biodiversity worldwide. A globally co-ordinated research effort is needed in order to understand the drivers and implications of such changes and to predict effects of global change on plant species phenology and related ecosystem processes. 2. Here, we present the rationale of the PhenObs initiative botanical gardens as a global phenological observation network. The initiative aims to collect data on plant phenology in A cc ep te d A rt ic le
