Chemical Composition and Lactic Microflora of Adjuevan, A Traditional Ivorian Fermented Fish Condiment

Adjuevan, a traditional Ivorian naturally fermented fish prepared from the Atlantic bumper Chloroscombrus chrysurus, was assessed for its proximate and lactic acid microflora compositions in order to establish its nutritive and technological usefulness. Significant differences were observed between the fresh and the fermented fish for all the chemical substance analyzed except for the lipid content. Adjuevan contained between 69.65 and 71.25% moisture, 12.16 and 12.36% lipid, 21.21 and 26.81% protein. The mean value for the ash, Ca, P, Na and K content of the adjuevan were 10.5%, 4.16 mg/g, 3.82 mg/g, 0.72 mg/g and 0.67 mg/g respectively. There were no significant differences between samples from the different processors. The genera and species of lactic acid bacteria isolated and identified from the fresh fish and the adjeuvan samples were Leuconostoc lactis, Lactobacillus fermentum, Pediococcus sp. , Streptococcus sp. The highest load was obtained with Lactobacillus fermentum, 9.4x10 to 3.7x10 cfu/g. The fermentation 3 4 does not adversely affect the composition of Chloroscombrus chrysurus. Lactic acid bacteria found could participate in the technological processing and contribute to keeping the quality of the adjuevan.

The evaluation of cellular uptake efficiency and tumor-targeting ability of MPEG–PDLLA micelles: effect of particle size

In this study, we successfully prepared MPEG–PDLLA polymer micelles with two different particle sizes, A and B. DLS and TEM assays demonstrated that the particle sizes of the polymer micelles A and polymer micelles B were about 25 nm and 150 nm respectively. The stability of the MPEG–PDLLA polymer micelles in vitro revealed that the free Cy5.5 dye had been successfully loaded into the polymer micelles as a fluorescence marker and the fluorescence wasn’t quenched until 72 h. The cellular uptake of the polymer micelles was time-dependent and micelles A (particle size 25 nm) showed a higher efficiency to be internalized into the cytoplasm of MCF-7 cells than micelles B (particle size 150 nm). Furthermore, in vivo and in vitro biodistribution and tumor-targeting of polymer micelles MPEG–PDLLA were investigated in female MCF-7 tumor-bearing balb/cA-nu mice with an IVIS imaging system. The results showed that polymer micelles A (particle size 25 nm) had a time dependent biodistribution and tumor site accumulation in mice bearing MCF-7 tumors. Meanwhile, the NIR fluorescence intensity of polymer micelles B (particle size 150 nm) in tumor sites showed a pattern of a rise, a peak and then a decline. What’s more, the distribution of the polymer micelles in the tissue slices demonstrated the same results. Consequently, the results indicated that the micelles with a smaller particle size (25 nm) could be more efficiently internalized into cells and increase the enhanced permeation and retention (EPR) effect in tumor tissue. Therefore, a reasonable small size of micelles may be a key factor for a high-performance anti-cancer drug delivery system.
Prediction of the Influence of Liquid Loading on Wellhead Parameters

Liquid loading is a common issue for gas wells. Obviously better predictions of liquid loading will help operators in reducing costs less shutdowns and improve revenue more production. The authors present an artificial neural network model for predicting the minimum flow rate for continuous removal of liquids from the wellbore. The model is developed using field data from different gas wells used to train a neural network model. The model was tested against actual field data that were not used in training phase. The results show that the developed model provides better predictions and higher accuracy than the published models.
Plasmonic Coupling Effect on Spectral Response of Silver Nanoparticles Immobilized on an Optical Fiber Sensor

The localized surface plasmon resonance (LSPR) of silver nanoparticles during immobilization on the U-bent sensor fiber probe has been studied. The gradual wavelength shift of the peak resonance due to the increment of the number of nanoparticles on the fiber surface has been attributed to the plasmonic coupling effect. Since the immobilization is random, the shift of the resonance as well as the broadening of the absorption spectrum depends on the distribution of the nanoparticles. To get the insight of the cause of this spectral behavior, we have incorporated the two-particle coupling approximation and assumed that the particles form pairs with its nearest neighbors. The distribution of pairs was obtained from the microdimensional images of fiber surfaces. The collective response from the contributions of these pairs was calculated using the theoretical framework of discrete dipole approximation (DDA). The shifts of the resonance as well as the broadening of the calculated spectra were found to be in ex.
Solid-State Structures of Base-Free Lithium and Sodium Tetraphenylborates at Room and Low Temperature: Comparison with the Higher Homologues MB(C6H5)4 (M = K, Rb, Cs)

Lithium and sodium tetraphenylborate were subjected to an X-ray diffraction analysis to elucidate the solid-state structures at room (RT) and low temperature (LT). As in the potassium, rubidium, and cesium tetraphenylborates the lithium tetraphenylborate forms polymeric columns consisting of alternating Li+ and [B(C6H5)4]− ions. The lithium cations are coordinated by four η1-bonded phenyl rings of two tetraphenylborate anions. Each polymeric column is surrounded by six adjacent columns. The RT structure of sodium tetraphenylborate is almost identical with those of the heavier salts KB(C6H5)4, RbB(C6H5)4, and CsB(C6H5)4 (columns of alternating M+ and [B(C6H5)4]− ions; each column is surrounded by four adjacent columns). The LT structure of NaB(C6H5)4 is different and resembles the solid-state structure of the lithium salt. In addition, single-crystal structures of RbB(C6H5)4 (LT) and CsB(C6H5)4 (RT) have been determined for the first time at the temperature specified.

Abstract Rh/γ-Al2O3 nanocatalysts with different metal loading were synthesized by two different techniques i. e. microemulsion and microwave irradiated solvothermal technique. Synthesized nanocatalysts were then successfully implemented for the hydrogenation of 4’,4”(5”)-di-tert-butyldibenzo-18-crown-6 ether (DTBuB18C6) at 70 bar, 353–393 K temperature and 5 h. It was observed that 3 wt% nanocatalyst obtained by microemulsion technique exhibited higher catalytic activity and resulted 40 % conversion with high selectivity towards cis-syn-cis di-tert-dicyclohexano-18-crown-6ether (CSC DTBuCH18C6).
Physical Activity, Sedentary Behavior, and Time in Bed Among Finnish Adults Measured 24/7 by Triaxial Accelerometry

Background: Studies measuring physical activity (PA) and sedentary behavior on a 24/7 basis are scarce. The present study assessed the feasibility of using an accelerometer at the hip while awake and at the wrist while sleeping to describe 24/7 patterns of physical behavior in working-aged adults by age, sex, and fitness. Methods: The study was based on the FinFit 2017 study where the physical behavior of 20- to 69-year-old Finns was assessed 24/7 by triaxial accelerometer (UKKRM42; UKK Terveyspalvelut Oy, Tampere, Finland). During waking hours, the accelerometer was kept at the right hip and, during time in bed, at the nondominant wrist. PA variables were based on 1-min exponential moving average of mean amplitude deviation of the resultant acceleration signal analyzed in 6-s epochs. The angle for the posture estimation algorithm was used to identify sedentary behavior and standing. Evaluation of time in bed was based on the wrist movement. Fitness was estimated by the 6-min walk test. Results: A total of 2,256 eligible participants (mean age 49.5 years, SD = 13.5, 59% women) wore the accelerometer at the hip 15.7 hr/day (SD = 1.4) and at the wrist 8.3 hr/day (SD = 1.4). Sedentary behavior covered 9 hr 18 min/day (SD = 1.8 hr/day), standing nearly 2 hr/day (SD = 0.9), light PA 3.7 hr/day (SD = 1.3), and moderate to vigorous PA 46 min/day (SD = 26). Participants took 7,451 steps per day (SD = 2,962) on average. Men were most active around noon, while women had activity peaks at noon and at early evening. The low-fit tertile took 1,186 and 1,747 fewer steps per day than the mid- and high-fit tertiles (both p < .001). Conclusions: One triaxial accelerometer with a two wear-site approach provides a feasible method to characterize hour-by-hour patterns of physical behavior among working-aged adults.
Sorbed Anthracene Degradation by Sophorolipid Producing Yeasts

The organic pollutan adsorption/desorption process by microbial degradation had been less studied than metal ones. The sorption assays alone did not predict desorption, due to hysteresis, irreversibility, fixed compounds in different sites, with diverse desorption rates. Most of the studies dealt with bacteria rather than filamentous fungi and yeasts. So, our aims were to isolate yeasts from polluted sediments, to quantify its potential to uptake anthracene (An) and to evaluate the bioavailability by a desorption model. Yeasts were isolated from hydrocarbon-polluted samples, 40-isolates grew in anthracene-plates. Molecular characterization was achieved by sequence analysis of the ITS1-5.8S rRNA-ITS4 and 26S rRNA regions; morphological and physiological determination were also done. Candida parasilopsis , Pichia anomala and Rhodothorula mucilaginosa were the prevalent yeasts. An-degradation was assessed in soil-systems with 0, 50, 100, 150, 200 and 250 I¼g An/l, 3 differentes sorbens types, organic carbon, organic nitrogen, PAHs, sand:silt:clay, pH and cation exchange capacity. Sophorolipids excretion were confirmed by HPLC, UV-detector with active fraction at 9.669 min (RT 9.646 min = sophorolipid-standard). A desorption model with equilibrium, nonequilibrium and nondesorption areas, was applied to explain the experimental data, An-transformation was greater in the organic liquid-phase than in the soil-sorbed ones; the desorption-coefficients and soil components were negatively correlated with the kinetic parameters. The An-release depended on the sophorolipid excretion, soil matrix and particles sizes. Desorption parameters significantly fitted the yeast uptake, with R 2 = 0.97, R 2 = 0.90 and R 2 = 0.97 for C. parasilopsis , P. anomala and R. mucilaginosa, respectively.
A structural, spectroscopic and theoretical study of an o-vanillin Schiff base derivative involved in enol-imine and keto-amine tautomerism

The potassium salt of the Schiff base obtained by condensation of 2-hydroxy-3-methoxybenzaldehyde (o-vanillin) and 2-aminoethanesulfonic acid (taurine) in a methanol potassium hydroxide solution was characterized by crystallographic, spectroscopic and DFT methods. The compound crystallizes in the monoclinic C2/c space group with a = 37.539(4), b = 5.9129(4), c = 26.321(5) A, β = 121.10(2)° and Z = 8 molecules per unit cell. The crystallographic data reveal that two different anionic molecules, which constitute a tautomeric pair, coexist in the crystal. This finding is supported by FTIR, Raman and electronic measurements in methanol solution. The main crystallographic differences between the bonding structures occur along the shortest chemical path linking the oxygen and the nitrogen atom of the OH and CN group. Both tautomeric forms are stabilized by strong O–H⋯N and N–H⋯O intramolecular hydrogen bonds. Optimized geometrical parameters and calculated spectroscopic features obtained by DFT calculations show a very good agreement with the experimental data. Moreover, 1H NMR, 13C NMR and electronic measurements in DMSO solution show the prevalence of the enol-imine tautomer in this solvent.
Long-range attractive forces extending from the alumina’s nanolayer surface in aqueous solutions

Aluminum oxide-hydroxide nanolayer with a thickness of approximately 1.2 nm is electroadhesively deposited onto silicious support material with large surface area of about 50 m2/g, forming a highly electropositive composite of boehmite nanolayer in the form of monocrystalline oxide/hydroxide (α-Al2O3·H2O) on the second electronegative solid. The composite can be viewed as a sphere with a rough surface and charge density of approximately 0.08 C/m2. This creates a significant electric field with negligible screening (ka ≪ 1) in the region close to the surface of the nanocomposite. This field attracts nano- and micron-sized particles from as far as 200 μm in a few seconds, many orders of magnitude greater than conventional Derjaguin–Landau–Verwey–Overbeek (DLVO) theory, which predicts only nanometer-scale effects arising from the presence of the surface. The strong electric field on the surface is then able to retain small particles such as viruses, atomically thin sheets of graphene oxide, RNA, DNA, proteins, dyes as well as heavy metals such as cobalt, arsenic, and lead. Alumina’s nanolayer surface can be further functionalized by adding other sub-micron or nano-sized particles to target a specific contaminant. An example is shown where alumina nanolayer is coated with nano-sized iron monohydrate to yield an arsenic sorbent that shows high sorption capacity.

A Scope of Qualitative and Quantitative About Representation of Social, Economic, Psychological and Health Conditions of Indirex Female Sex Worker Reproduction During the Covid-19

The Outbreack of Coronavirus disease 2019 (Covid-19) in 2019 with the consequent global spread (World Health Organization, necessitated the WHO to declare the disease as a pandemic of Public Health Emergency of International Concern (PHEIC). Since then, the pandemic has resulted in massive global health challenges that require significant behavior change with its resultant psychological and social burdens on individuals and their livelihoods as many nations resorted to the directives of the WHO by imposing various restrictions such as restriction of movement closures of business, quarantine of suspected cases and isolation of the sick for treatment among others. The representation of Life quality, in this case social, economic, psycological conditions, and reproductive health of Indirex Female Sex Workers Post- Pub Café Closing was poor, so that the government’s contribution was required to help deal with the effect of post Pub Café Closing During Pandemic Covid 19.
Magnetic Activated Carbon Derived from Biomass Waste by Concurrent Synthesis: Efficient Adsorbent for Toxic Dyes

The development of advanced carbon nanomaterials that can efficiently extract pollutants from solutions is of great interest for environmental remediation and human safety. Herein we report the synthesis of magnetic activated carbons via simultaneous activation and magnetization processes using carbonized biomass waste from coconut shells (Cb’s) and FeCl3·6H2O as precursor. We also show the ability of the materials to efficiently extract toxic organic dyes from solutions and their ease of separation and recovery from the solutions using a simple bar magnet. Textural characterization shows that the materials are microporous. Further analyses of the deconvoluted XPS spectra and X-ray diffraction patterns reveal that the materials possess magnetite, maghemite and hematite. SEM and TEM images show that an increase in the ratio of FeCl3·6H2O:Cb leads to an increase in the material’s magnetic properties. The point of zero charge (pHpzc) indicates that the materials have acidic characteristics. Adsorption kineti.
Particle size effects on transformation kinetics and phase stability in nanocrystalline TiO2

Abstract Kinetic studies conducted primarily between 465 and 525 ℃ demonstrate that the rate of the polymorphic anatase to rutile transformation increases dramatically when the reacting anatase is very finely crystalline. Coarsening of the reactant anatase and product rutile crystallites occurs simultaneously with the transformation. Kinetic behavior and quantification of transformation rate as a function of average crystallite size indicate that the increase in favorable nucleation sites is a likely cause of increase in transformation rate at small crystallite sizes. Additionally, experimental evidence supports the reversal of stabilities of anatase and rutile at small crystallite sizes. It is proposed that the reversal of stabilities is the result of rutile having a higher surface energy than the anatase phase. Data for coarsening kinetics of anatase and rutile supports the prediction that the surface energy of rutile is significantly larger than that of anatase. Thermodynamic data and theoretical estimates are used to show that a 15% greater surface energy for rutile causes the total free energy of rutile to be greater (less negative) than anatase at crystallite diameters in the few nanometer range. Given the fact that anatase and rutile structures have no polymerized octahedral fragments in common, this may be significant in determining the nature of the nucleated phase.
Mass Coupling by Means of Lagrange Polynomials in the CFD Simulation of High-Velocity Dense Sprays

This investigation is a continuation of a previous study by these authors in which a Lagrange polynomial interpola tion method was developed to evaluate spray source terms and also to distribute the source terms onto the gas mesh; the method was applied to the liquid gas momentum exchange. For this investigation, the method has been extended to the mass exchange between the liquid and gas phases due to evaporation. The Lagrange polynomial interpolation and source term distribution methods are applied to the liquid gas mass and momentum exchange and are evaluated for evapo rating sprays using KIVA3 as a modeling platform. These methods are compared with the standard "nearest neigh bor" method of KIVA3, and experimental data are used to establish their validity. The evaluation criteria used include the liquid and vapor spray penetration, gas veloc ities and the computational stability. It has been found that the application of this method to mass coupling for evaporating sprays leads to improved mesh indepen dence of the liquid spray penetrations and an increased stability of the numerical solver.

Characterization and optimization of SAPO-34 catalysts synthesized by mixed templates in MTO reaction

The effects of templating on the catalytic performance of SAPO-34 catalyst have been investigated in conversion of methanol to olefins. SAPO-34 catalysts were synthesized using a different combination of morphine, tetraethyl ammonium hydroxide (TEAOH) and triethylamine (TEA) as structure-directing agents during synthesis of gel with nominal composition as 1Al2O3:1P2O5:0.4SiO2:2yTEAOH:2xTEA:2(1-(x+y))morpholine:70H2O. The different SAPO-34 samples were characterized by XRD, SEM, FTIR, BET, EDX and TPD techniques. Increasing TEAOH in synthesis gel led to decreasing mean crystal size. The catalytic performance of the synthesized catalysts was tested in MTO reaction at 410C and a feed WHSV of 6.5 1/h. The catalyst synthesized by combination of tri-templates exhibited highest light olefins yield in 100% methanol conversion. The optimum values (X=0.17, Y=0.34) were obtained by central composite design and response surface contour plots.
