An ab initio effective solid-state photoluminescence by frequency constraint of cluster calculation

Measuring the photoluminescence of defects in crystals is a common experimental technique for analysis and identification. However, current theoretical simulations typically require the simulation of a large number of atoms to eliminate finite-size effects, which discourages computationally expensive excited state methods. We show how to extract the room-temperature photoluminescence spectra of defect centers in bulk from an ab initio simulation of a defect in small clusters. The finite-size effect of small clusters manifests as strong coupling to low frequency vibrational modes. We find that removing vibrations below a cutoff frequency determined by constrained optimization returns the main features of the solid-state photoluminescence spectrum. This strategy is illustrated for the negatively charged nitrogen vacancy defect in diamond (NV −) presenting a connection between defects in solid state and clusters; the first vibrationally resolved ab initio photoluminescence spectrum of an NV − defect in a nanodiamond; and an alternative technique for simulating photoluminescence for solid-state defects utilizing more accurate excited state methods.
Macromolecule-like Aspects for a Colloidal Suspension of an Exfoliated Titanate. Pairwise Association of Nanosheets and Dynamic Reassembling Process Initiated from It

A layered protonic titanate of lepidocrocite-type, HxTi2-x/4□x/4O4·H2O (x ∼ 0.7; □, vacancy), has been exfoliated on the action of an aqueous solution of tetrabutylammonium (hereafter TBA) hydroxide, which resulted in a stable colloidal suspension. A colloidal aggregate centrifuged from the suspension was examined by an in situ X-ray diffraction technique under conditions where drying speed was controlled. The diffraction immediately after separation from the liquid phase was principally amorphous except for a series of sharp reflections detected in a small angle scattering region. On the basis of the line profile analysis, the latter diffraction feature was accounted for by the fundamental intersheet interference of a spacing >10 nm, which demonstrates the existence of a novel associated pair of the titanate nanosheets accommodating a large volume of water cluster between them. These XRD data provide persuasive evidence for delamination into single layers. Upon drying, the amorphous halo disappeared and .
A Slip-Link Model of Branch-Point Motion in Entangled Polymers

In melts of asymmetric three-arm star polymers in which a short arm is attached to two long, equal-length arms, the existing “tube” theory fails to predict how rapidly the motion of the branch-point becomes quenched when the length of the third, short, arm grows from zero length, for which the two other arms form a reptating linear chain, to a length equal to the other two arms, for which reptation is quenched. We use a simulation method that represents entanglements between two chains as “slip-links” that allow local relaxation of both chains when an end of either chain passes through the slip-link. We include an extreme form of branch-point motion in this algorithm and find that it can explain the anomalously rapid quenching of the branch-point if we assume that the time scale of the branch-point motion is set by the time required for the short arm to escape all entanglements, including those newly created while others are destroyed. The algorithm successfully predicts the linear viscoelasticity of H-po.
Analysis of Chiral and Achiral Medium Based Coplanar Waveguide Using Improved Full Generalized Exponential Matrix Technique

In this work, an analytical study of the electromagnetic propagation in a complex medium-based suspended three-layer coplanar waveguide (CPW) is carried out. The study aims at a numerical calculation of the dominant hybrid mode complex propagation constant in the CPW printed on a bianisotropic substrate. The herein considered bianisotropy is characterized by full 3×3 tensors of permittivity, permeability and magnetoelectric parameters. The study is based on the numerical derivation of the Green's functions of such a complex medium in the spectral domain. The study is carried out using the Full Generalized Exponential Matrix Technique based on matrix-shaped compact mathematical formulations. The Spectral Method of Moments (SMoM) and the Galerkin's procedure are used to solve the resulting homogeneous system of equations. The effect of the chiral and achiral bianisotropy on the complex propagation constant is particularly investigated. Good agreements with available data for an anisotropic-medium-based suspended CPW structure are achieved. Various cases of chiral and achiral bianisotropy have been investigated, and particularly, the effect on the dispersion characteristics is presented and compared with cases of isotropic and bianisotropic Tellegen media.
Synthesis of NaY Zeolite Molecular Sieves from Calcined Diatomite

NaY zeolite molecular sieves have been synthesized using diatomite as a main starting material via a hydrothermal method. In this approach, the mixture of diatomite and Na2CO3 in mass ratio of 1.0/1.46 was first calcined at temperature of 830 °C for about 1.5 h. The calcined materials were then dissolved in water to obtain a solution and the composition is 15.1 Na2O : 1 Al2O3 : 11.5 SiO2 : 832 H2O. The solution was used to synthesize NaY zeolite by the crystals seeds (27.76Na2O·1.00Al2O3·25.07SiO2·305.66H2O) via hydrothermal treatment. The hydrothermal temperature is 100 °C and the percentage of added crystal seeds is 10% (volume) relative to calcined materials. The obtained zeolite was identified by X-ray diffraction (XRD), and was characterized by scanning electron microscope (SEM), transmission electron microscope (TEM) and nitrogen sorption analysis, which showed that a high yield of NaY type with a high crystalinity was obtained.
Effects of high molecular mass anionic polymers on paper sheet formation

The effects on the formation of paper produced by dissolving trace amounts of high molecular mass, anionic polymers in suspensions of papermaking fibers have been examined in the laboratory and on a pilot paper machine. The addition of trace quantities of high molecular mass anionic polymers were found to result in significant improvements in the small-scale uniformity of handsheets and machine-made sheets. The anionic polymers have minimal tendency to become associated with fibers and colloidal particles. Trace quantities of high molecular mass polymers in solution are known to markedly increase the elongational viscosity of the solution with little or no measurable increase in shear viscosity. A mechanism is proposed t o explain the improvements in formation based upon the way in which the increased extensional viscosity of the suspending medium reduces the intensity of turbulence and the interactions between fibers. The increased elongational viscosity resulting from the large dissolved polymers also reduces dewatering rates during drainage and pressing. All else being equal, these reductions in dewatering rates will restrict the application of these materials to situations where production is not limited by drainage.
A method with inertial extrapolation step for split monotone inclusion problems

ABSTRACT The purpose of this paper is to study the convergence analysis of an iterative algorithm with inertial extrapolation step for finding an approximate solution of split monotone inclusion problem in real Hilbert spaces. Weak convergence of the sequence of iterates generated from the proposed method is obtained under some mild assumptions. Some special cases of the general problem are given and we give some numerical implementations to support the theoretical analysis and give justification for the addition of the extrapolation step in the proposed method.

The Basic Body Awareness Therapy attempts to achieve the quality of body movement through muscular motor patterns free of pressure and tension with the aim of promoting body awareness and optimizing the person’s body scheme. The aim of this narrative review of the literature is to determine the benefits that Basic Body Awareness Therapy can provide as a treatment for Eating Disorders. The studies including in this review of the literature supported the efficacy of Basic Body Awareness Therapy as an adjunctive therapy of Eating Disorders, but many studies have important limitations regarding their methodology. The role of the Physiotherapist is gaining prominence in the treatment of patients with Eating Disorders, as physiotherapeutic technics such as Basic Body Awareness Therapy provide significant improvement in the quality of life, psychiatric symptoms, and physical health of the affected patients.
Initial Assessment of the COSMIC-2/FORMOSAT-7 Neutral Atmosphere Data Quality in NESDIS/STAR Using In Situ and Satellite Data

A COSMIC-1/FORMOSAT-3 (Constellation Observing System for Meteorology, Ionosphere, and Climate-1 and Formosa Satellite Mission 3) follow-on mission, COSMIC-2/FORMOSAT-7, had been successfully launched into low-inclination orbits on 25 June 2019. COSMIC-2 has a significantly increased Signal-to-Noise ratio (SNR) compared to other Radio Occultation (RO) missions. This study summarized the initial assessment of COSMIC-2 data quality conducted by the NOAA (National Oceanic and Atmospheric Administration) Center for Satellite Applications and Research (STAR). We use validated data from other RO missions to quantify the stability of COSMIC-2. In addition, we use the Vaisala RS41 radiosonde observations to assess the accuracy and uncertainty of the COSMIC-2 neutral atmospheric profiles. RS41 is currently the most accurate radiosonde observation system. The COSMIC-2 SNR ranges from 200 v/v to about 2800 v/v. To see if the high SNR COSMIC-2 signals lead to better retrieval results, we separate the COSMIC-2–RS41 comparisons into different SNR groups (i.e., 0–500 v/v group, 500–1000 v/v group, 1000–1500 v/v group, 1500–2000 v/v group, and >2000 v/v group). In general, the COSMIC-2 data quality in terms of stability, precision, accuracy, and uncertainty of the accuracy is very compatible with those from COSMIC-1. Results show that the mean COSMIC-2–RS41 water vapor difference from surface to 5 km altitude for each SNR groups are equal to −1.34 g/kg (0–500 v/v), −1.17 g/kg (500–1000 v/v), −1.33 g/kg (1000–1500 v/v), −0.93 g/kg (1500–2000 v/v), and −1.52 g/kg (>2000 v/v). Except for the >2000 v/v group, the high SNR measurements from COSMIC-2 seem to improve the mean water vapor difference for the higher SNR group slightly (especially for the 1500–2000 v/v group) comparing with those from lower SNR groups.
The Psychosocial Effects of Having a Sibling with Autism Spectrum Disorder

Siblings play an important role in one another’s overall development; thus, the sibling relationship is an important subsystem within the family unit. However, in families where one child has an autism spectrum disorder diagnosis, the dynamics between siblings may be different than in families with typically developing children due to the associated deficits in communication. Therefore, this mixed-method study examined the perceptions of six typically developing children regarding their relationship with a sibling with autism. Parents were heterosexual couples, and families were white and mostly middle class. Semi-structured interviews and questionnaires regarding the sibling relationship were administered to the typically developing child. Identification of major themes followed by focused coding was conducted to capture the essence of what was said and to categorize the most frequent themes. Overall, typically developing children highlighted both positive and negative features of their relationships, for example play, feeling proud, embarrassment, and anger. Additionally, children seemed to be at a loss for coping strategies they considered helpful, perhaps due to their own poor and/or developing emotional regulation skills. The findings emphasize the need to support typically developing children and their personal and social development.
Study on Dynamic Stall Control of Rotor Airfoil Based on Coflow Jet

In this study, a dynamic stall control strategy, called the co-flow jet (CFJ), is applied to the rotor airfoil. The effect of the CFJ on the unsteady dynamic stall characteristics of the rotor airfoil is numerically investigated via numerical simulations of the unsteady Reynolds-averaged Navier-Stokes (URANS) equations coupled with the Spalart-Allmaras (S-A) turbulence model. The numerical methods are validated by a NACA0012 pitching airfoil case and a NACA6415 airfoil case based on the CFJ, and good agreement with experiments is found. Via the study of the typical conditions of CFJ control to suppress the dynamic stall of the OA212 rotor airfoil, it is verified that this method has a good effect on dynamic stall suppression. The diffusion and blending of the turbulent shear layer between the CFJ injection jet and the main flow excite the main flow and enhance its ability to resist the reverse pressure gradient; this suppresses the generation and development of the separation vortex, thereby enhancing the aerodynamic characteristics, improving the hysteresis effect, and increasing the system stability. On this basis, the control parameters of the CFJ are further studied, including the influences of the jet momentum coefficient and the positions and sizes of the injection and suction slots on suppressing the dynamic stall of the rotor airfoil. It is found that there is a jet momentum coefficient that optimizes the suppression effect of the dynamic stall of the rotor airfoil. Moreover, the position of the injection slot is found to have a greater effect on the dynamic stall suppression, while the size of the injection slot and the position and size of the suction slot have little effect.
The role of regional value chains in fostering regional integration in Southern Africa

ABSTRACT Regional integration is making steady progress in Africa and a key objective is to improve the prospects for industrialisation by expanding the regional market. The paper draws on a combination of trade data analysis and industry case studies to better understand the links and synergies between regional value chains and regional integration. The trade data and case studies of two diverse sectors (garments and food retailing) demonstrate the expansion and diversity of regional trade and regional value chains in Ssouthern Africa. This increasingly diverse composition of regional exports is suggestive of an opportunity to further enhance industrial development through intra-regional trade. From a political economy perspective, the long term sustainability of Southern African regionalism will require that the benefits are widely spread. In turn this requires the recognition of the importance of regional industrial policy, which takes account of the dynamics driving global and regional value chains and facilitates regional linkages.
Effect of Differentiated Nitrogen Fertilization on the Enzymatic Activity of the Soil for Sweet Potato (Ipomoea batatas L. [Lam.]) Cultivation

The experiment was conducted between 2015–2017 in the Research Station for Cultivar Testing in Uhnin (51°34′ N, 23°02′ E), in Luvisols developed from sandy loam soils. Soil samples for the tests of enzymatic activity were collected after the crop was harvested. The measurements included: the content of dehydrogenases, phosphatases, urease and protease, as well as total organic carbon, total nitrogen and mineral nitrogen in soil, based on standard methods. The research results point to changes in the enzymatic activity of light soil under the influence of varied nitrogen fertilization. In objects fertilized with this ingredient, the activity of the analysed enzymes was significantly higher than in the control soil, except for combinations fertilised with 150 kg ha−1 N characterised by the highest accumulation of N-NO3− in soil. The activity of dehydrogenases, phosphatases and urease changed as the nitrogen dose increased. The polynomial regression analysis enabled a better understanding of those dependences. In the case of dehydrogenases, phosphatases and urease, a third-degree curvilinear relation of enzymatic activity to nitrogen fertilisation was observed (a fourth-degree relation was found, with a coefficient R2 in those equations amounting to =0.958, 0.977, 0.979, respectively) and in the case of protease activity, a fourth-degree relation, with coefficient R2 = 0.989. However, soil acidity did not have a significant influence on either the enzymatic activity or physico-chemical characteristics of soil under the cultivation of sweet potatoes. The C:N ratio turned out to be significantly negatively related to the content of the enzymes dehydrogenase (Adh), phosphatase (AF), urease (AU) and protease (AP) as well as the content of total nitrogen, especially its ammonium form (N-NH4). The obtained results indicate the usefulness of research on enzymatic activity as an indicator of soil reaction to nitrogen fertilization and will enable maintenance of the optimal biological balance of cultivated soils.
Impact of Trona-Based SO2 Control on the Elemental Leaching Behavior of Fly Ash

Trona (Na3HCO3CO3·2H2O) injection has been used to control SO2 emissions in coal-fired power plants. This study evaluated the impact of trona injection on fly ash physical and chemical characteristics, especially the leaching characteristics. One set of paired coal fly ash samples, collected from a full-scale power plant with and without trona injection for SO2 control, was used. The results showed that trona injection introduced significant amounts of soluble sodium compounds into the fly ash, elevated the fly ash pH, reduced the ash surface area, and changed the fly ash morphology. A comparison of 30 constituents in leachates from both ashes demonstrated that trona ash leached significantly greater amounts of Na, sulfate, chloride, fluoride, total inorganic carbon (TIC), and oxyanions, especially As and Se. Effects of the liquid/solid (L/S) ratio, pH, dry storage time, and leaching time on As and Se leaching and speciation were examined. AsV, SeIV, and SeVI were the As and Se species in trona ash leacha.

The Effect of Extract of Canarian Nuts on Reduction of Total Cholesterol Levels of Hyperglicemic Rat

This study aims to determine the effect of walnut extract (Canarium indica) on the total cholesterol levels of hyperglycemic Wistar rats (Rattus norvegicus L). Experimental research with pre-post-test control design. The samples in this study were 28 rats induced by alloxan to become hyperglycemic. The test animals were divided into four groups, each consisting of seven: negative control (Na CMC 1%), positive control (metformin 150 mg / Kg BW), walnut extract group 300 mg / Kg BW (0.06g / 200gr BW), and extract 600 mg / Kg BW (0.12 / 200g BW). The intervention was given walnut extract for 21 days. Total cholesterol levels were measured by the Easytouch Multi-Monitoring System. This study used SPSS with paired t-test and ANOVA test. The results showed a significant reduction in cholesterol levels in all groups after treatment (p <0.05). There was a significant difference in the reduction of total cholesterol levels between groups with a value of p = 0.037. The results of the posthoc test showed a difference in the reduction in total cholesterol levels between the 300 extract group, 1% Na CMC, and metformin and the 600 extract group with 1% Na CMC p-value <0.05, there was no difference between the 600 extract group and the metformin group. p> 0.05. Walnut extract was effective in reducing alloxan-induced fasting blood sugar levels of mice. Total cholesterol levels in hyperglycemic rats experienced a significant decrease after 21 days of intervention with walnut extract 300 and 600 mg/kg BW, but only walnut extract at a dose of 600 mg/kg BW had the same effectiveness as metformin.

Nutritional literacy status and its related factors in students of Yasuj University of Medical Sciences.

Introduction: it is necessary to evaluate the level of nutritional literacy before performing any educational measure-ment related to nutrition. As a matter of fact, an effective education is the result of proportional education level with the level of understanding the target group. This study is aimed to determine nutritional literacy status. Objectives: In this study, students of Yasuj University of Medical Sciences were considered as research sample set. Then, factors affecting the nutritional literacy status were de-signed and implemented for the study. Methods: A total of 397 students were selected for this descriptive-analytical study. A systematic sampling method was developed and nutritional literacy status was assessed through a localized questionnaire based on the Evaluation Instrument of Nutrition literacy on Adults (EINLA). SPSS Statistics 23 software package was employed for statistical analysis. Results: In this study, students participated in 11 disciplines with the mean and standard deviation of 22.04 ± 2.33 years. The results showed that the mean score of students’ nutritional literacy was 24.9 out of 35. According to the results, 1% of students were dealt with the problem of inadequate nutritional literacy and 50.9% and 48.12% of students had borderline nutritional literacy and adequate nutritional literacy, respectively. In addition, the results revealed that higher semester students had more nutritional literacy than other students. Furthermore, nutritional literacy was signifi-cantly correlated with the semester, field of study, students’ residence and body mass index (P<0.05). Conclusion: The results demonstrated that most of the students had borderline and sufficient nutritional literacy, but they had a significant weakness in determining their nutritional units.
