Relation between EBS of Some Syrian Clay Minerals and Atterberg Limits

The demand of clay as a raw material for many industries has increased in recent years due to their physical–chemical and plastic properties. The main property that distinguish the clay is its plasticity therefore; several attempts have been made to achieve a numerical index to emphasize the relationship between mineralogy and plasticity. (EBS) Equivalent Basal Spacing maybe is the most recent contribution for this purpose. In this paper, we analyze different types of Syrian clay samples, from five locations, by measuring their Atterberg limits and their mineralogical composition, in order to check the validity of the EBS method. As consequence, we find a positive connection between Atterberg limits and the relative amount of phyllosilicates present in samples. The EBS factor provides a good relationship between mineralogy and plasticity of the samples, by giving an easy and reliable correlation based on the direct determination of the liquid limit and plasticity index based on the mineralogical composition of the studied clays. We recommend for further researches to study the relations between EBS and Atterberg limits for other types of clay around Syria in order to validate EBS parameters in most applications.
Structural and Electrical Characterization of La and Mn Co-Substituted Bismuth Ferrite Thin Films

Bismuth ferrite thin films with 10% La and 5% Mn (BLFMO) have been deposited using Pulsed laser deposition. It is found that oxygen pressure has pronounced effect on the structural and electrical properties of BLFMO thin films. The leakage current density increases with the oxygen pressure. At 0.007 mbar, the leakage current density is found to be in the order of 10−7A/cm2 at 200 kV/cm. The remnant polarization is 73 μC/cm2 at 200 kV/cm. Fatigue endurance has been studied for optimized film and found that films are almost fatigue free after 108 pulses. There is only 3% change in the polarization up to 106 seconds as revealed by retention test.
Quantum Affine Wreath Algebras

To each symmetric algebra we associate a family of algebras that we call quantum affine wreath algebras. These can be viewed both as symmetric algebra deformations of affine Hecke algebras of type $A$ and as quantum deformations of affine wreath algebras. We study the structure theory of these new algebras and their natural cyclotomic quotients.

High-momenta estimates for the Klein−Gordon equation: long-range magnetic potentials and time-dependent inverse scattering

The study of obstacle scattering for the Klein−Gordon equation in the presence of long-range magnetic potentials is addressed. Previous results of the authors are extended to the long-range case and the results the authors previously proved for high-momenta long-range scattering for the Schrödinger equation are brought to the relativistic scenario. It is shown that there are important differences between relativistic and non-relativistic scattering concerning the long range. In particular, it is proven that the electric potential can be recovered without assuming the knowledge of the long-range part of the magnetic potential, which has to be supposed in the non-relativistic case. The electric potential and the magnetic field are recovered from the high-momenta limit of the scattering operator, as well as fluxes modulo 2 π ? > around the handles of the obstacle. Moreover, it is proven that for every v ˆ ∈ S 2 ? > , A ∞ ( v ˆ ) + A ∞ ( − v ˆ ) ? > can be reconstructed, where A ∞ ? > is the long-range part of the magnetic potential. A simple formula for the high-momenta limit of the scattering operator is given in terms of magnetic fluxes over handles of the obstacle and long-range magnetic fluxes at infinity, that are introduced in this paper. The appearance of these long-range magnetic fluxes is a new effect in scattering theory.
Effects of Subtoxic Concentrations of Atrazine, Cypermethrin, and Vinclozolin on microRNA-Mediated PI3K/Akt/mTOR Signaling in SH-SY5Y Cells

Endocrine-disrupting chemicals (EDCs) are different natural and synthetic chemicals that may interfere with several mechanisms of the endocrine system producing adverse developmental, metabolic, reproductive, and neurological effects in both human beings and wildlife. Among pesticides, numerous chemicals have been identified as EDCs. MicroRNAs (miRNAs) can regulate gene expression, making fine adjustments in mRNA abundance and regulating proteostasis. We hypothesized that exposure to low doses of atrazine, cypermethrin, and vinclozolin may lead to effects on miRNA expression in SH-SY5Y cells. In particular, the exposure of SH-SY5Y cells to subtoxic concentrations of vinclozolin is able to downregulate miR-29b-3p expression leading to the increase in the related gene expression of ADAM12 and CDK6, which may promote a pro-oncogenic response through the activation of the PI3K/Akt/mTOR pathway and counteracting p53 activity. A better understanding of the molecular mechanisms of EDCs could provide important insight into their role in human disease.
Experimental and modeling study of hydrophobic associative polyacrylamide for enhanced oil recovery in carbonate reservoir

In this study, hydrophobic associative polyacrylamide (HAPAM) was used in conjunction with the chemical flooding technique in a low-permeability carbonates reservoir. To test the efficacy of the proposed method, both a model and an experiment were created. Experiments were run to compare the relative permeability (Kr) curves, oil recovery rates, and rheological, physical, aging time, and petrophysical features of brine water and polymer flooding in a core. The purpose of these tests was to show how HAPAM can be used to boost oil recovery. Computer Modelling Group (CMG), a simulator, was then used. An oil-and-brine (or HAPAM solution) grid in three dimensions (3D) was developed. The validity of the suggested simulator was established by comparing its results to those obtained from commercial software and from most of the brine or polymer flooding experiments. The developed simulator was used to undertake additional research into the non-Newtonian flow of brine or polymer solution in porous media. The experimental consequences indicated that the polymer solution has a shear thinning viscosity curve and flow behavior index. Shear thinning, viscosity, shear resistance, aging time, density, surface tension, and interfacial tension, and the water wet relative permeability curve are all improved by the adding 1500 ppm HAPAM to brine water. was about 80%. There was a strong agreement between the results of the modeling study and the experiments. (CMG).
Population‑based prostate‑specific antigen screening for prostate cancer may have an indirect effect on early detection through opportunistic testing in Kusatsu City, Shiga, Japan

Prostate cancer is the most common genitourinary cancer in men. Population-based serum prostate-specific antigen (PSA) testing is used to screen men for the early detection of asymptomatic prostate cancer. The present study compared the features of patients with prostate cancer in Kusatsu City, the only municipality in Shiga Prefecture of Japan to implement organized PSA screening, with those in other municipalities. The target population for organized PSA screening by mail invitation was men ≥50 years. Patients were pathologically diagnosed via prostate biopsy because of elevated serum PSA. This multicenter observational study was subsequently conducted in 14 hospitals. The following information was extracted from patient records: age, reason for PSA testing, initial PSA level, Gleason score, clinical stage, and place of residence. Risk classification was defined as low, intermediate, high, and advanced. Each patient was stratified according to their city/town. A total of 984 patients diagnosed with prostate cancer in Shiga in 2012 and 2017 were analyzed, of which 955 (97%) were opportunistically tested, with the remaining 29 (3%) assessed by organized screening. In Kusatsu, 93 patients were diagnosed, of whom 26 (28%) were detected by organized screening. By contrast, only three of 891 patients (0.3%) were detected by organized screening in other municipalities. Of patients in Kusatsu, cases identified by opportunistic testing had a higher initial PSA value (P=0.010) than those identified by organized screening. However, patients detected through opportunistic testing in Kusatsu City were younger (P=0.034), had a lower PSA value (P=0.001), and improved risk classification (P<0.001) than those in other municipalities. It was concluded that more patients were diagnosed with early-stage cancer by organized PSA screening. Furthermore, population-based PSA screening in Kusatsu City may have indirectly affected early detection, even by opportunistic testing.
Irreversible transfer processes of thermoelectric generators

We discuss a novel tool based on heat flow diagrams for analyzing irreversible processes associated with thermoelectric devices and discuss some ambiguous descriptions and errors in related investigations. We consider thermoelectric generators as a paradigm of a heat engine cycle and determine the heat flow distribution by treating the one-dimensional heat transfer differential equation. Representative heat flow diagrams are used to study the influence of internal and external irreversible processes of heat conduction and Joule heat generation.

Discovery of 5-Methylthiazole-Thiazolidinone Conjugates as Potential Anti-Inflammatory Agents: Molecular Target Identification and In Silico Studies

A series of previously synthesized 5-benzyliden-2-(5-methylthiazole-2-ylimino)thiazoli- din-4-one were evaluated for their anti-inflammatory activity on the basis of PASS predictive outcomes. The predictive compounds were found to demonstrate moderate to good anti-inflammatory activity, and some of them displayed better activity than indomethacin used as the reference drug. Structure–activity relationships revealed that the activity of compounds depends not only on the nature of the substituent but also on its position in the benzene ring. The most active compounds were selected to investigate their possible mechanism of action. COX and LOX activity were determined and found that the title compounds were active only to COX-1 enzymes with an inhibitory effect superior to the reference drug naproxen. As for LOX inhibitory activity, the derivatives failed to show remarkable LOX inhibition. Therefore, COX-1 has been identified as the main molecular target for the anti-inflammatory activity of our compounds. The docking study against COX-1 active site revealed that the residue Arg 120 was found to be responsible for activity. In summary, the 5-thiazol-based thiazolidinone derivatives have been identified as a novel class of selective COX-1 inhibitors.
Diagnosis of fibromyalgia: diagnostic feasibility and accuracy of thermography

Introduction: Studies have suggested using thermography as a resource to diagnose fibromyalgia, although there has been no evidence confirming this hypothesis so far. Objective: To evaluate the sensitivity and specificity of computerized infrared thermography as an auxiliary method for diagnosing fibromyalgia. Methods: It is a diagnostic accuracy studywith cross-sectional design. One hundred and three individuals were evaluated for global pain using the Visual Analogue Scale. The measurement of pain at tender points was assessed by algometry, and skin temperature was assessed by thermography. To evaluate sensitivity and specificity, the analysis was performed using the Receiver Operating Characteristic Curve, measured by the area under the curve with their respective confidence intervals. Results: Thermography has not been very sensitive or specific for pain (tender points) and diagnosis of fibromyalgia, according to the evaluation of the Receiver Operating Characteristic Curve, with an area under the curve equal to or lower than 0.75. Conclusion: In this study the thermography was not sensitive and specific as a tool for diagnosing the fibromyalgia syndrome. This study highlights important clinical implications concerning the current methods for diagnosing it, which, despite all efforts, are still subjective and poorly reproducible.
Effects of Nutritional Practices and Production Systems on Small Ruminants’ Health in Rural Households in Ekiti State, Nigeria

The study assessed the effect of nutritional practices and production systems on the health of small ruminant animals reared among rural households in Ekiti State. A total number of 120 rural households were interviewed using a multi-stage random sampling procedure to elicit information from them. About 78.32 percent were within their active age range, 50.00 percent were married with minimum household size of 5 persons, had least educational qualification and 41.66 percent reared sheep and goats. Disease outbreak (50.00%), accident (33.33%) and stillbirth (16.66%) are the common factors responsible for mortality experienced by the farmers, while diarrhea is the prevalent disease experienced by them. More than half (58.13%) of the respondents practices self-medication by purchasing antibiotics meant for humans from medicine stores and very few of them (18.33%) received intervention from the government in terms of medication. Only 33.00% of them offer supplementary feeding to their animals during the dry season. Chi-square analysis revealed a significant relationship (p=0.05) between nutritional practices and the health system of the small ruminants. Also, the Pearson Moment Product Correlation also revealed that a significant correlation (rcal= 0.927) exists between production systems and the health of small ruminants in the study area which is significant at 0.05 level of probability. The study, concludes that if animals are poorly managed and fed, they could be predisposed to diseases and injuries.
C1,1 regularity for degenerate complex Monge–Ampère equations and geodesic rays

ABSTRACT We prove a C1,1 estimate for solutions of complex Monge–Ampère equations on compact Kähler manifolds with possibly nonempty boundary, in a degenerate cohomology class. This strengthens previous estimates of Phong–Sturm. As applications we deduce the local C1,1 regularity of geodesic rays in the space of Kähler metrics associated to a test configuration, as well as the local C1,1 regularity of quasi-psh envelopes in nef and big classes away from the non-Kähler locus.
Dynamic Type Matching

Problem definition: We consider an intermediary’s problem of dynamically matching demand and supply of heterogeneous types in a periodic-review fashion. Specifically, there are two disjoint sets of demand and supply types, and a reward for each possible matching of a demand type and a supply type. In each period, demand and supply of various types arrive in random quantities. The platform decides on the optimal matching policy to maximize the expected total discounted rewards, given that unmatched demand and supply may incur waiting or holding costs, and will be fully or partially carried over to the next period. Academic/practical relevance: The problem is crucial to many intermediaries who manage matchings centrally in a sharing economy. Methodology: We formulate the problem as a dynamic program. We explore the structural properties of the optimal policy and propose heuristic policies. Results: We provide sufficient conditions on matching rewards such that the optimal matching policy follows a priority hierarchy among possible matching pairs. We show that those conditions are satisfied by vertically and unidirectionally horizontally differentiated types, for which quality and distance determine priority, respectively. Managerial implications: The priority property simplifies the matching decision within a period, and the trade-off reduces to a choice between matching in the current period and that in the future. Then the optimal matching policy has a match-down-to structure when considering a specific pair of demand and supply types in the priority hierarchy.
Schmidt games and non-dense forward orbits of certain partially hyperbolic systems

Let $f:M\rightarrow M$ be a partially hyperbolic diffeomorphism with conformality on unstable manifolds. Consider a set of points with non-dense forward orbit: $E(f,y):=\{z\in M:y\notin \overline{\{f^{k}(z),k\in \mathbb{N}\}}\}$ for some $y\in M$ . Define $E_{x}(f,y):=E(f,y)\cap W^{u}(x)$ for any $x\in M$ . Following a method of Broderick, Fishman and Kleinbock [Schmidt’s game, fractals, and orbits of toral endomorphisms. Ergod. Th. & Dynam. Sys. 31 (2011), 1095–1107], we show that $E_{x}(f,y)$ is a winning set for Schmidt games played on $W^{u}(x)$ which implies that $E_{x}(f,y)$ has Hausdorff dimension equal to $\dim W^{u}(x)$ . Furthermore, we show that for any non-empty open set $V\subset M$ , $E(f,y)\cap V$ has full Hausdorff dimension equal to $\dim M$ , by constructing measures supported on $E(f,y)\cap V$ with lower pointwise dimension converging to $\dim M$ and with conditional measures supported on $E_{x}(f,y)\cap V$ . The results can be extended to the set of points with forward orbit staying away from a countable subset of $M$ .
A RELAÇÃO ENTRE LUCRO BRUTO, LUCRO OPERACIONAL E LUCRO LÍQUIDO E OS RETORNOS FUTUROS NO BRASIL

Objetivo: O objetivo desse trabalho foi verificar qual das definições de lucro (lucro bruto, lucro operacional ou lucro líquido) tem melhor desempenho em explicar o comportamento futuro dos retornos no mercado brasileiro, e se esses resultados se mantêm ao se formar carteiras combinando a rentabilidade, índices book-to-market e BrF_Score. Método: Para tal, são utilizadas as regressões de dois estágios de Fama e MacBeth, o teste T2 de Hotelling e o modelo de três fatores de Fama e French, além da análise do excesso de retorno das carteiras construídas. A periodicidade do estudo é mensal, abrangendo o período de janeiro de 2010 até junho de 2019, totalizando 15.577 observações de 200 empresas. Resultados: Os resultados demonstram que o lucro líquido e o lucro operacional produzem as métricas de rentabilidade com os maiores poderes explicativos para o retorno de um mês à frente, além de produzirem as carteiras com maiores excessos de retorno, se comparadas às métricas de rentabilidade baseadas no lucro bruto. Contribuições: Portanto, a contribuição do trabalho foi demonstrar que o lucro líquido explica melhor o retorno futuro no mercado brasileiro, enquanto no mercado americano, existem evidências de que o lucro bruto desempenha este papel, e essas diferenças se dão pelas diferentes influências macroeconômicas sofridas por tais mercados.
Immunohistochemical evaluation of the cleft-affected scar tissue three decades post-corrective surgery: A rare case report

Abstract Cleft lip and palate are the most common congenital malformations which require early primary cleft surgery in all infants. The surgical treatment of cleft lip and palate deformities results in the formation of scar tissue. However, the scarred tissue has sparsely been immunohistochemically evaluated to date. Herein, we report the differences in the cellular expression of various proteins in the scar and nearby healthy tissue of a 35-year-old patient who underwent cleft correction surgery during infancy. The scar tissue showed basal cell proliferation, prominent cysts, and fibrotic connective tissue. An increased expression of both interleukin 1α (IL-1α) and IL-10 in the scar tissue was noted, although the balance favored an anti-inflammatory environment. No differences in the expression of matrix metallopeptidase-2 (MMP-2) and TIMP-2 were found whilst an increased expression of PAX-9 and MSX-1 was observed in the scar tissue, which co-localized with RYK expression. Temporal studies like the present one can aid in advancing our understanding of the longitudinal processes governing wound healing morpho-pathogenesis in cleft-affected patients.
Yellow Pigment from Fast-growing Marine Soil Bacteria Citricoccus sp. for Dyeing Cotton Fabrics

Aims: The study’s objective is to isolate, characterize pigment-producing bacteria from marine soil and to optimize culture parameters such as pH, temperature, carbon, nitrogen sources to enhance the pigment production. The obtained pigment was used to dye cotton fabrics and woollen thread. Place and Duration of Study: The samples were collected from the Marina beach, Chennai, Tamil Nadu and the study was carried out at the Department of Animal Biotechnology, Madras Veterinary College, Chennai, between January 2021- April 2021. Methodology: From the soil sample fast-growing yellow pigmented bacteria was isolated and the morphological characteristics were observed. Gram staining, biochemical test, sugar fermentation test, motility test was performed and 16S rDNA sequencing was done. Pigment was extracted through solvent extraction method, characterized through UV-Spec and FTIR. The phytochemicals test was done and the culture conditions were optimized to bring out maximum pigment yield. The pigment was then used to dye cotton fabrics and woollen threads. Results: The isolated yellow-pigmented bacteria was identified as Citricoccus sp. and the pigment is confirmed as carotenoid compound and through optimizing the culture conditions, the pigment production was increased significantly. The woollen thread and cotton fabrics were dyed effectively and uniformly with the use of copper sulphate(CuSO4) as mordant. Conclusion: The result of this study reveals that Citricoccus sp. is a fast-growing bacterium capable of producing a higher amount of pigment in 24-hour period. Since it is confirmed to be a carotenoid compound, it is safe to be used as a dye. The extraction process is cost-effective and economical, this study can be expanded to explore the potential applications of the pigment in the textile and dyeing industries.
Further remarks on liftings of crossed modules

In this paper we define the notion of pullback lifting of a lifting crossed module over a crossed module morphism and interpret this notion in the category of group-groupoid actions as pullback action. Moreover, we give a criterion for the lifting of homotopic crossed module morphisms to be homotopic, which will be called homotopy lifting property for crossed module morphisms. Finally, we investigate some properties of derivations of lifting crossed modules according to base crossed module derivations.
