Numerical analysis of the electromechanical behavior of high-field REBCO coils in all-superconducting magnets

Despite the excellent improvements in high fields resulting from the adoption of REBa2Cu3O x (REBCO)-coated conductors (CCs), the resulting stress and strain due to winding tension, cooling stress, and the screening-current-induced Lorentz force may lead to severe plastic deformation and degradation of superconductivity. Therefore, it is essential to understand the comprehensive electromechanical behavior and deformation mechanism of high-field REBCO magnets. In this paper, multistep finite element analysis is designed to simulate the electromechanical behavior of REBCO coils after the winding, coolingdown, and charging processes. All major constituent materials including the mandrel, CCs, cowinding reinforcement, and over-banding are considered in the mechanical models to emulate contact–separation behavior between them. In addition to contact nonlinearity, an intrinsic elastoplastic property is introduced to predict the plastic deformation observed in experiments. To reveal the screening-current effect, the distributions of the screening current and the magnetic field are analyzed by solving the T-A formulation of Maxwell’s equations using a homogeneous technique. Then, with the electromagnetic load acting as a body force, the electromagnetic stress and strain are computed and experimentally validated for a pancake coil, including the transport current and external field. Finally, the electromechanical behavior under a Lorentz load is investigated by considering the accumulation of stress and strain due to winding tension and cooling down. The simulation results reveal that the winding tension and thermal stress affect the final stressstates in the fully charged state and therefore the electromechanical properties. Both plastic deformation and possible degradation are more likely to occur in the outermost tape of several pancakes due to the influence of screening-current-induced stress and strain. In addition, this work further analyzes the effect of the current sweep reversal method, which could be favorable in reducing the screening-current-induced high stress and strain in the steady state.
Effective Microporosity for Enhanced Adsorption Capacity of Cr (VI) from Dilute Aqueous Solution: Isotherm and Kinetics

The adsorbent pore structure significant to enhanced adsorption capacity of Cr (VI) from dilute aqueous solution is evaluated. As reference, low-cost micro-mesoporous activated carbon (AC) of high basicity, mesoporosity centred about 2.4 nm, and effective microporosity centred about 0.9 nm was tested for removal of Cr (VI) from dilute aqueous solution in batch mode. At pH 2 the low-cost AC exhibited highly improved Langmuir Cr (VI) capacity of 115 mg/g which was competitive to high performance commercial AC. A Comparison with treated characterization results of literature adsorbents/ACs showed that moderate to high effective micropore volume of average pore-size Original Research Article Mukosha et al.; CSIJ, 19(4): 1-12, 2017; Article no.CSIJ. 34082 2 about 0.9 ± 0.1 nm is critical for increased adsorption capacity of Cr (VI) from dilute aqueous solutions. The mesostructure of the tested low-cost AC was associated with rapid kinetics that was fitted by the Pseudo-second kinetics model. While Biot numbers suggested slight significant contribution of intraparticle diffusion. It is hoped that this study may be a useful contribution to development of effective adsorbents for the efficient abatement of toxic Cr (VI) from wastewater and water.
A link between surface air temperature and extreme precipitation over Russia from station and reanalysis data

Precipitation extremes are widely thought to intensify with global warming due to an exponential growth following the Clausius–Clapeyron (C–C) equation which links the atmosphere water vapor saturation pressure with air temperature. However, a number of recent studies based on station and reanalyzes data for the contemporary period showed that scaling rates between extreme precipitation and temperature strongly depend on temperature range, moisture availability, and a region of interest. Being performed for some regions, such estimates, however, lack for Northern Eurasia, where prominent temperature changes and rapid shift from large-scale to convective precipitation are observed. Here, we examine the scaling between daily precipitation extremes and surface air temperature (SAT) over Russia for 1966–2017 using meteorological station data and for 1979–2020 using ERA5 reanalysis. The precipitation-temperature relation is examined for total precipitation and, separately, for convective and large-scale precipitation types. In winter, we reveal a general increase in extreme precipitation of all precipitation types according to the C–C relationship. For the Russian Far East region, the stratiform precipitation extremes scale with SAT following even super C–C rates, about two times as fast as C–C. However, in summer we find a peak-like structure of the precipitation-temperature scaling, especially for the convective precipitation in the southern regions. Extreme precipitation reaches their peak values at the temperature range between 15 °C and 20 °C. At higher temperatures, the negative scaling prevails. Analyzed data show a pronounced decrease in relative humidity with increasing surface temperatures beyond the 15 °C–20 °C threshold. This indicates that moisture availability is the major factor for the peak-shaped relationship between extreme precipitation and temperature revealed by our analysis.
Comprehensive Chemistry of HeH+ in the Early Universe

The recent detection of the helium hydride ion (HeH+) in the planetary nebula NGC 7027 has inspired studies revisiting the dominant processes for its formation and destruction. Because radiative association is the primary formation mechanism for the helium hydride ion at all redshifts, and many early universe chemistry models rely on accurate results for calculations of destruction rates, we explicitly computed rovibrationally distinguished partial cross sections and rate coefficients of helium hydride formation via radiative association, and modeled the abundance of HeH+ in the early universe using recently available rate coefficients for all relevant formation and destruction reactions. The rate coefficients for the radiative association formation reaction of HeH+ and radiative charge transfer in He+ + H collisions were obtained using two distinct methods. Our newly calculated rate coefficients along with other recently reported He chemistry reactions and updated cosmological parameters were incorporated into a new calculation of the abundance of HeH+ for redshifts between z = 10 and 4000. We find that the abundance of the helium hydride ion is at least three orders of magnitude larger than previous predictions for redshifts near z = 20. Rovibrationally distinguished radiative association rate coefficients are given as a function of temperature, and the significance of stimulated radiative association for redshifts z > 400 is also shown.
BuildingNet: Learning to Label 3D Buildings

We introduce BuildingNet: (a) a large-scale dataset of 3D building models whose exteriors are consistently labeled, and (b) a graph neural network that labels building meshes by analyzing spatial and structural relations of their geometric primitives. To create our dataset, we used crowdsourcing combined with expert guidance, resulting in 513K annotated mesh primitives, grouped into 292K semantic part components across 2K building models. The dataset covers several building categories, such as houses, churches, skyscrapers, town halls, libraries, and castles. We include a benchmark for evaluating mesh and point cloud labeling. Buildings have more challenging structural complexity compared to objects in existing benchmarks (e.g., ShapeNet, PartNet), thus, we hope that our dataset can nurture the development of algorithms that are able to cope with such large-scale geometric data for both vision and graphics tasks e.g., 3D semantic segmentation, part-based generative models, correspondences, texturing, and analysis of point cloud data acquired from real-world buildings. Finally, we show that our mesh-based graph neural network significantly improves performance over several baselines for labeling 3D meshes. Our project page www.buildingnet. org includes our dataset and code.
The Role Of Cd56 And Ck19 Immunohistochemical Staining In The Diagnosis Of Papillary Carcinoma In Thyroid Lesions Among Iraqi Patients

Background: The differentiation between papillary, follicular and other form of thyroid cancer relies mainly of histological feature; however, significant overlap in these features exists and it sometime very difficult, based on sole morphological features, to identify specific histological pattern. Thus, the role of immunohistochemistry has been proposed to aid in the diagnosis of papillary carcinoma of thyroid gland and both CD56 and CK19 gain wide acceptance among pathologists worldwide. Aim of study: To evaluate the immunohistochemical expression of CD56 and CK 19 in thyroid tissues obtained from patients with papillary thyroid carcinoma. Patients and methods: 45 patients with papillary carcinoma of the thyroid gland with an age range of 26 to 50 years. immunohistochemical staining using two markers, CK19 and CD56. Were used. The streptavidin –biotin method staining protocol were used. The presence of brown reaction product of more than 10% of tumor cells at the site of the target antigen is indicative of positive reactivity. The extent of staining by CK-19, were calculated according to the percentage of positive cells as: No staining: 0; < 25% stained cells: 1+; 25% to 75% stained cells: 2+; > 75% stained cells: 3+, whereas the intensity of staining by CK-19 was evaluated as no staining: 0; faint: 1+; and strong: 2+. Results: Positive CD56 expression was detected in 48.9 % of cases and distributed as following: weak staining pattern was seen in 13 (28.9 %), 4 (100.0 %) of males and 9 (22.0 %) of females, being more significantly encountered in men (p = 0.012); moderate staining pattern was never seen and strong staining pattern was seen in a total of 9 (20.0 %) and was significantly restricted to women (p < 0.001). Positive CK19 expression was reported in a total of 42 (93.3 %) of cases and it was distributed as following: weak staining pattern was restricted to women accounting for 3 (7.3 %), moderate staining pattern was also restricted to women accounting for 3 (7.3 %) and strong staining pattern was more frequently associated with male patients in comparison with female patients, 4 (100.0 %) versus 29 (70.7 %), respectively, but the difference was statistically insignificant (p = 1.000). Conclusion: combining the immunohistochemical findings of CD56 and CK19 with conventional histopathological evaluation of thyroid lesions greatly increase the accuracy of diagnosing papillary carcinoma.
Food ecology of Hassar affinis (Actinopterygii: Doradidae) in two lakes of a wet zone of international importance in Northeast Brazil

The study aimed to describe the aspects of trophic ecology and feeding strategy of the Hassar affinis species in two lakes in the Baixada Maranhense region a wetland of international ecological interest (Site Ramsar). Individuals were collected monthly for one year. 372 stomachs were analyzed, of which 246 were from Lake Cajari and 126 from Lake Viana. The diet composition of the species was analyzed using the Frequency of Occurrence, Volumetric and Food Importance Index method. The result indicated that 49.1% of stomachs had content Lake Cajari. For Lake Viana, the number of stomachs analyzed indicated that 65.8% were full. The most consumed food itens by the species in Cajari were Mollusk of the species Benthonella tenella, Insect larvae of the order Coleoptera, Odonata, Diptera and Ephemeroptera. In Lake Viana, the same items were present. During the dry and rainy season in Lake Cajari there were differences in diet (item/prey) where the species consumed in greater percentage the item Mollusc in the dry period and in the rainy season Insect larvae, however for Viana lake the species did not show significant variation in feeding concerning seasonality. Regarding ontogenetic, H. affinis showed differences in feeding, both in sex and in the maturation stage. Thus, according to the analysis of stomach contents, it was confirmed that the species H. affinis has an omnivorous benthic feeding habit with a generalist strategy, evidencing the importance of the ecosystem for the food chain in both lakes.

Seed priming improves Salvia hispanica L. seed performance under salt stress

Salvia hispanica L. is an alternative crop cultivated by farmers who want to diversify their production. However, this species is sensitive to salinity, which affects its germination negatively. Seed priming with different attenuators is a technique with potential to mitigate the effects of salt stress. Thus, the objective of this study was to evaluate the effect of seed priming with the use of different attenuators on the germination, growth, and organic solute accumulation of S. hispanica seedlings under salt stress. The experimental design was completely randomized, with treatments distributed in a 4 × 5 factorial scheme, corresponding to four seed priming treatments and five osmotic potentials, with four replicates of 50 seeds in each treatment. The seed treatments consisted of presoaking seeds for 4h in salicylic acid, gibberellic acid, and distilled water and the control treatment, which did not involve soaking. These seeds were germinated at osmotic potentials of 0.0, -0.1, -0.2, -0.3, and -0.4 MPa, using NaCl as an osmotic agent to simulate the different salinity levels. Among all the treatments implemented, S. hispanica seed priming with salicylic acid was the most efficient in mitigating the salt stress effects.
Mental Health during COVID-19 Pandemic

In the 21st century, any pandemic, especially, SARS-CoV-2 is a global burden due to high incidence, mortality, and mutation rate. Although several techniques have already been identified to control the pandemic or treat patients and causes of adverse impact on mental health, relatively only, fewer researchers have little concern about finding effective mitigation strategies to improve mental health. Therefore, this study aimed to find some common and unique approaches to manage mental health during a pandemic. Some strategies for the better management of mental health induced by SARS-CoV-2 infections are required for all classes of peoples. Early management is vital, and those must be associated with frontline workers and people staying at home, particularly in isolation centers and already identified as active cases. Experts have pointed out the need to pay specific attention to proper daily life. To manage abnormal mental conditions, such as anxiety, mood, personality, and psychotic disorder during the pandemic; social media, meditation, and psychological motivation with adequate diet, exercise, and sleep have significant roles in regulating some biological mechanism, incredibly immune, hormonal, and neural process. Management of mental health is mandatory for all at the time of the SARS-CoV-2 pandemic. We can consider all of the strategies mentioned above to treat mental health during and after the COVID19 pandemic
circRNA_PTPRA functions as a sponge of miR-582-3p to regulate hepatocellular carcinoma cell proliferation, migration, invasion and apoptosis

Hepatocellular carcinoma (HCC) is a lethal disease and one of the most common types of cancer. HCC is associated with exponentially increasing morbidity and mortality rates. Accumulating evidence has identified circular RNAs (circRNAs) to be regulators of cancer progression. However, to the best of our knowledge, the potential effect of circRNA protein tyrosine phosphatase receptor type A (circRNA_PTPRA) in HCC and its mechanism remain unknown. The present study aimed to assess the effects and underlying mechanism of circRNA_PTPRA in a HCC Huh-7 cells model. The sites of interaction between circRNA_PTPRA and microRNA (miR)-582-3p were predicted using the StarBase software and verified using dual luciferase reporter and RNA immunoprecipitation (RIP) assays in Huh-7 cells. HCC cell viability, apoptosis, migration and invasion were measured using MTT, ﬂow cytometry and Transwell assays, respectively. The expression levels of circRNA_PTPRA, miR-582-3p, cyclin D1, MMP-9, Bcl-2 and Bax were analyzed using reverse transcription-quantitative PCR and western blotting. The results of the dual luciferase reporter and RIP assays demonstrated that miR-582-3p directly targeted circRNA_PTPRA. Compared with the human normal hepatocyte cell line, THLE-2, the expression levels of circRNA_PTPRA were upregulated, which were found to be inversely correlated with those of miR-582-3p expression in Huh-7 and HCCLM3 cells. miR-582-3p overexpression using mimics suppressed cell proliferation, migration and invasion, whilst downregulating cyclin D1 and MMP-9 expression in Huh-7 cells. In addition, transfection of HCC cells with the miR-582-3p mimic promoted apoptosis by downregulating Bcl-2 expression and upregulating Bax expression in Huh-7 cells. Knocking down circRNA_PTPRA expression using small interfering RNA (siRNA) markedly downregulated circRNA_PTPRA expression levels and upregulated miR-582-3p expression, but was reversed by co-transfection with the miR-582-3p inhibitor. Furthermore, reduced HCC cell proliferation, migration and invasion, increased levels of cell apoptosis, upregulated Bax expression and downregulated cyclin D1, MMP-9 and Bcl-2 expression were all observed after knocking down circRNA_PTPRA. All these effects aforementioned were reversed by co-transfection with the miR-582-3p inhibitor. In conclusion, findings from the present study suggested that circRNA_PTPRA may regulate HCC cell proliferation, invasion, apoptosis and migration by sponging miR-582-3p. This indicates that the circRNA_PTPRA/miR-582-3p axis may represent a potential target for HCC diagnosis and treatment.
PHYSICO-CHEMICAL PROPERTIES OF CERIUM- AND FERRIC-DOPED TITANIUM HYDROXIDES SYNTHESIZED BY TWO METHODS

Two types of materials on the base of titanium hydroxides are synthesized by co-precipitation and sol–gel method using pure and technical precursors. The ratio of metals in the samples after thermal treatment is determined by XRF analysis. Morphology of the composites obtained is characterized by low-temperature nitrogen adsorption/desorption technique. Adsorption of phosphate ions which are considered to be serious water pollutants has been studied onto the individual titania samples and titania, doped by ceria and ferric oxides. The samples have been obtained by two methods and were studied in the wide region of pH. All the investigated samples have demonstrated the high removal ability for phosphate anions at pH = 2. The sample of titania, doped by cerium and ferric, obtained by sol-gel method exhibits the highest adsorption capacity towards the adsorbed ions of 3.6 mmol/g. The adsorption isotherms have been fitted to the Langmuir, Freundlich and Temkin models. The equilibrium data of non-cerium-doped samples agreed satisfactory with the Langmuir isotherm model. Temkin model of isotherm describes well the experimental data regardless the method used for synthesis with the highest values of the coefficient of determination.

Empirical Analysis of the Relationship between Poverty and Growth in Ethiopia: Micro-Panel Data Evidence from Amhara Region

Reduction of poverty is still a vital concern and main challenge for Ethiopia, the second most populous country after Nigeria, in the SSA. With the government’s consistent implementation of its Poverty-Reduction-Strategy (PRS) Ethiopian households experienced a decade of remarkable progress in wellbeing. Poverty in Ethiopia declined at an annual average of 2.32 percentage points since 1995. Besides, Ethiopia, having registered high economic growth since 2005 at an average of 10.8 percent per annum, stands out as one of the fastest growing economies in the world. Despite all this, Ethiopia is amongst the poorest countries in the world, with a very low human-development ranking, or 174 th out of 188 countries according to the UNDP’s human development report 2015. According to the estimation of the WB, UNDER PEER REVIEW
