Improvement in the Flux Uniformity of the Solar Dish Concentrator System through a Concave Quartz Window

A nonuniform and high-strength heat flux load would reduce the working efficiency, safety, and in-service life of a cavity receiver. Four types of concave quartz windows, including conical, spherical, sinusoidal, and hyperbolic tangent, were proposed to be used in the cylindrical cavity receiver of a solar dish concentrator system, which can improve the flux uniformity and reduce the peak concentration ratio of the receiver. For each concave quartz window, 36 structural schemes were offered. Based on the Monte Carlo ray-tracing method, the results showed that the nonuniformity coefficient of the receiver was 0.68 and the peak concentration ratio was 1320.21 by using a plane quartz window. At the same time, when the receiver is in the best optical performance, it is the receiver with sinusoidal, conical, spherical, and hyperbolic tangent quartz windows, respectively. The optical efficiency of the receiver with the above four types of quartz windows was basically the same as that of the receiver with the plane quartz window, but their nonuniformity coefficients were reduced to 0.31, 0.35, 0.36, and 0.39, respectively, and the peak concentration ratio was reduced to 806.82, 841.31, 853.23, and 875.89, respectively. Obviously, the concave quartz window was better than the plane quartz window in improving the flux uniformity. Finally, a further study on the sinusoidal quartz window scheme of all of the above optimal parameter schemes showed that when the installation position of the receiver relative to the dish concentrator was changed, the flux uniformity of the receiver could continue to improve. When the surface absorptivity of the receiver was reduced, the optical efficiency would be reduced. For the parabolic dish concentrator with different focal distance, the concave quartz window can also improve the uniformity of the flux distribution of the cylindrical cavity receiver.
Fungal contamination in rainbow trout eggs in Kermanshah province propagations with emphasis on Saprolegniaceae

Fungal infection in the eggs of freshwater fish is well known as a problematic disease. The aim of the present study was to isolate and identify parasitic and saprophytic fungi from affected eggs of rainbow trout at two fish hatchery in Kermanshah province. The sample were inoculated in culture media (SDA,CMA,GPA and stilled water with cotton seed culture) at room temperature (18-24°C). 17 species of fungi isolated from the fungal eggs. Five fungi species that isolated in this study were belonged to the saprolegniaceae family including Saprolegnia paraitica, Saprolegnia lapponica ,Saprolegnia ferax, Saprolegnia hypogyna and Saprolegnia diclina . Another fungi that isolated in this study were, Fusarium oxyparum , Fusarium npoa , Fusarium sp. , Penicilium citrinium, Penicillium expansum, Aspergillus treuse, Aspergillus clavatus, Cladosporium sp. , Alternaria sp. , Helmintosporium sp. , Pscilomyces sp. , Mocur . It seems that Saprolegnia parasitica with 26.8 percent of isolation was the most important fungal infestation of egg in kermanshah trout hatcheries. Mocur with 19.6% had the most frequency after S. parasitic and Fusarium, Aspergillus and Pescillomyces with 2.45% had the lowest frequency. In this study S. ferax , S. hypogyna and S. diclina are reported from Iran for the first time.
Relationship between Surgery under General Anesthesia and the Development of Dementia: A Systematic Review and Meta-Analysis

Objective To investigate the association between exposure to general anesthesia and the development of Alzheimer's disease (AD) and dementia by reviewing and integrating the evidence from epidemiological studies published to date. Methods We searched MEDLINE, EMBASE, and Google Scholar to identify all relevant articles up to April 2018 reporting the risk of AD/dementia following exposure to general anesthesia and finally updated in February 2020. We included patients older than 60 or 65 years who had not been diagnosed with dementia or AD before the study period. The overall pooled effect size (ES) was evaluated with a random-effect model. Subgroup analyses were conducted and possibility of publication bias was assessed. Results A total of 23 studies with 412253 patients were included in our analysis. A statistically significant positive association between exposure to general anesthesia and the occurrence of AD was detected in the overall analysis (pooled ES = 1.11, 95%confidence interval = 1.07–1.15), but with substantial heterogeneity (pχ2 < 0.001, I2 = 79.4). Although the overall analysis revealed a significant association, the results of the subgroup analyses were inconsistent, and the possibility of publication bias was detected. Conclusion s. This meta-analysis demonstrated a significant positive association between general anesthesia and AD. However, considering other results, our meta-analysis must be interpreted with caution. Particularly, it should be considered that it was nearly impossible to discriminate the influence of general anesthesia from the effect of surgery itself on the development of AD. Further, large-scale studies devised to reduce the risk of bias are needed to elucidate the evidence of association between general anesthesia and AD. Trial registration.

Short Communication: Species diversity, habitat and abundance of Culicid mosquitoes in Bushehr Province, South of Iran

Khoobdel M, Keshavarzi D, Sobat H, Akbari M. 2020. Short Communication: Species diversity, habitat and abundance of Culicid mosquitoes in Bushehr Province, South of Iran. Biodiversitas 21: 1401-1406. Culicid-borne diseases are causes of substantial illness worldwide. Effective culicid control depends on up-to-date knowledge of ecology and dispersal of species. Hence, this entomological study was conducted from January December 2017 to provide baseline data on the distribution and ecology of mosquitoes in the Southwest of Iran. In total, 2530 specimens belonging to 14 different species were collected and identified, as follows: Culex hortensis, Cx. laticinctus, Cx. mimeticus, Cx. perexiguus, Cx. pipiens, Cx. modestus, Cx. sinaiticus, Cx. theileri, Cx. torrentium, Cx. tritaeniorhynchus, Anopheles stephensi, An. superpictus, An.dthali, and An.subpictus. Diversity analysis indicated higher species richness for uninhabited areas (Margalef 1/86). The average of Shannon diversity index ranged from 1.98 to 2.10. Differences between urban and uninhabited areas were significant according to the diversity t-test (P = 0.024, t = 2.26). The analysis of beta biodiversity showed that rural and uninhabited areas were the closest environments in their specific composition (Whittaker index = 0.130). These findings could be useful in vector control program.

SNMM most frequently occurs in the nasal cavity (70%) and maxillary sinus (14%), typically as black patches. Overall, SNMM harbors a very poor prognosis; 5-year survival is less than 30%. Nasal cavity tumors confer a better prognosis than sinus melanoma. The primary management for SNMM is surgery, when feasible, followed by adjuvant radiotherapy. Recent studies suggest that immunotherapy may confer survival benefit to patients with advanced disease. The multidisciplinary team approach has been shown to optimize treatment, reduce costs, and minimize adverse events, while maximizing the chances for cure.
Estimation of GPS L2 Signal Observables Using Multilayer Perceptron Artificial Neural Networks for Positional Accuracy Improvement

En las ultimas decadas, debido a la creciente movilidad de personas y bienes, el rapido crecimiento de los usuarios de dispositivos moviles con servicios basados en la ubicacion ha aumentado la necesidad de informacion geoespacial. En este contexto, el posicionamiento utilizando los datos recopilados por los Sistemas Globales de Satelite de Navegacion (multi-GNSS) ha ganado mas importancia en el campo de la geomatica. La calidad de las soluciones esta relacionada, entre otros factores, con el tipo de receptor utilizado en el trabajo. Para mejorar el posicionamiento con dispositivos de bajo costo y evitar gastos adicionales del usuario, este trabajo tiene como objetivo proponer la implementacion de una Red Neural Artificial (ANN) para estimar los observables del operador GPS L2. Para esto, se selecciono un modelo de red a traves de la tecnica de validacion cruzada (CV), se estimaron las observaciones y se analizo la precision de las soluciones. La tecnica CV demostro que un Perceptron multicapa con cuatro capas intermedias y uno con una capa intermedia son las configuraciones mas apropiadas para este problema. El procesamiento RINEX de doble frecuencia (con datos artificiales) revelo mejoras significativas. Para algunas pruebas, fue posible cumplir con las regulaciones de georreferenciacion de propiedad rural del Instituto Nacional de Colonizacion y Reforma Agraria (INCRA). Los resultados indican, por lo tanto, que la propuesta metodologica de la presente investigacion es muy prometedora para aproximar la calidad de posicionamiento accesible utilizando un receptor de doble frecuencia.
The Effect of Different Remineralizing Agents on Laser Bleached Enamel

One of the most required esthetic measures for patients with teeth discoloration or those who strive to have a beautiful smile and appearance is bleaching. The objective of this study is to analyze enamel morphological changes, chemical composition and microhardness following the application of 35% hydrogen peroxide, utilizing two various protocols for laser activation and the application of 4 different remineralizing agents. Materials and methods: In this study, 40 extracted human lateral and central incisors were chosen where the researcher categorized teeth into 2 groups consisting of 20 incisors, using two different laser-activated bleaching protocols. The researcher then subdivided each group into 4 subsets consisting each of 5 incisors where 4 remineralizing agents were applied to each bleached subset. Enamel surface morphology was studied by ESEM. Calcium and Phosphorus content were measured by EDAX and microhardness Vicker’s test was performed to study the alteration in enamel hardness. Pre- and post-demineralization (bleaching) investigations were conducted and then they were repeated following remineralization. Results: ESEM revealed the improvement of enamel surface morphology in the remineralized groups except in (HD) and (LD) groups. After remineralization, all groups had a higher weight percent of calcium (Ca) and phosphorus (P) levels than its levels after demineralization except in groups (HD) and Vicker’s hardness number in all groups showed significant increase except (HD) and (LD). Conclusion: The use of remineralizing agents containing casein phosphopeptide-amorphous calcium phosphate, fluoride or hydroxyapatite nanoparticles could improve the enamel morphology, microhardness and chemical composition of laser bleached enamel.
Faraday pilot-wave dynamics in a circular corral

A millimetric droplet of silicone oil may bounce and self-propel on the free surface of a vertically vibrating fluid bath due to the droplet’s interaction with its accompanying Faraday wave field. This hydrodynamic pilot-wave system exhibits many dynamics that were previously thought to be peculiar to the quantum realm. When the droplet is confined to a circular cavity, referred to as a ‘corral’, a range of dynamics may occur depending on the details of the geometry and the decay time of the subcritical Faraday waves. We herein present a theoretical investigation into the behaviour of subcritical Faraday waves in this geometry and explore the accompanying pilot-wave dynamics. By computing the Dirichlet-to-Neumann map for the velocity potential in the corral geometry, we can evolve the quasi-potential flow between successive droplet impacts, which, when coupled with a simplified model for the droplet’s vertical motion, allows us to derive and implement a highly efficient discrete-time iterative map for the pilot-wave system. We study the onset of the Faraday instability, the emergence and quantisation of circular orbits and simulate the exotic dynamics that arises in smaller corrals.
Assessment of Fluoride Intake from Rice Consumption by Using Tap Water Containing Fluoride for Rice Soaking Water

The people in Thailand generally soak sticky rice in water for 12–24 h before steaming and rinse jasmine rice before cooking. This study aimed at estimating fluoride intake from rice by the measuring rice consumption and examining factors affecting fluoride adsorption on jasmine rice and sticky rice in Buak Khang Subdistict, Chiang Mai Province, Thailand. It was found that 65.7% of 35 households still use tap water containing fluoride at 5.94 ± 0.29 mg/L of fluoride for rice soaking and rinsing. The amount of jasmine rice and sticky rice consumption was 0.096 ± 0.05 kg/meal and 0.114 ± 0.06 kg/ meal, respectively. The fluoride taken up into rice exhibited a positive correlation with the initial fluoride in water, the duration and water volume for rice soaking. The fluoride intake from jasmine rice and sticky rice based on the field survey was 0.004 ± 0.007 mg/kg-bw/day and 0.025 ± 0.024 mg/ kg-bw/day, respectively. The results of this study indicated that eating rice can significantly contribute to the total amount of fluoride intake; thus, it is recommended to use fluoride-free water or reducing time duration for rice soaking in areas using fluoride-containing groundwaters.

Method: In order to determine how well the identified model of the shortened version of the ZTPI (five subscales with 15 items) fits the Turkish adaptation, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed to understand the factor structure of ZTPI. Results: The results of the initial CFA suggested that the original factor structure of the ZPTI shortened version with 15 items fit the data for adolescents’ ratings of time perspective on the measures. The EFA revealed a five-factor structure for ZPTI with a shortened scale. CFA using competing models strategy also supported the five-factor structure. Convergent validity study yielded moderate correlations with other mental health indicators. Conclusion: The findings of the current study provided a good starting point for further ZTPI developments in Turkish culture. It is proposed that a proper balance between past, present, and future are now considered preconditions for success, mental health, and personal happiness. Considering the findings of the current study, time perspective may be useful for evaluating the personality concerns and well-being of clients in counseling and therapy.
Development of Multifunctional Coatings for Protecting Stones and Lime Mortars of the Architectural Heritage

ABSTRACT Unique multifunctional coatings, comprising a 3D superhydrophobic agent and two nanostructured photocatalysts (solar-light sensitive 50/50 and 10/90 TiO2-ZnO nano-heterostructures), compatible with the inorganic substrates of the Built Heritage, have been designed. The synthesized nanoparticles showed an enhanced photocatalytic activity (tested by NO degradation) as compared with the raw TiO2 and ZnO materials. Dispersing agents were used to optimize the coatings, avoiding agglomeration of the photocatalytic nanoparticles and increasing the stability of the suspensions. Four distinct dispersions were optimized and applied as coatings onto stony materials used in the Built Heritage, such as sandstone, lime mortar, granite and limestone. Their effectiveness was assessed by assessing hydrophobicity of the surfaces (static water contact angle), photocatalytic activity and self-cleaning as well as water vapour permeability of the treated specimens. These transparent coatings demonstrated high compatibility with the construction materials of the Architectural Heritage and showed a synergistic effect rendering a minimized water absorption, self-cleaning ability evidenced by the reduced adsorption of soiling deposits and a reasonable degradation of any trace that might be adsorbed, as well as a protecting hydrophobic environment for the photocatalyst.
Trypsin-hydrolyzed Corn Silk Proteins: Antioxidant Activities, in vitro Gastrointestinal and Thermal Stability, and Hematoprotective Effects

Corn Silk (CS), the silky hair-like structures protruding from the tip of the ear of corn, is essentially the elongated stigma of the female flower of corn. Although often discarded as an agricultural waste or by-product of corn cultivation, CS has also been used as traditional remedies in different parts of the world for the treatment of kidney stones, diuretic, prostate disorders, urinary infections and obesity [1,2]. Much research has attributed the bioactivities and health-promoting potential of CS to its phenolic compounds, in particular flavonoids and terpenoids. Various CS-based teas and other commercial products with claimed health-promoting benefits are available in the market [1]. CS contains 9–22% protein content on a dry mass basis, depending on its stage of maturity and corn variety [3,4]. Thus CS may be a promising source of food proteins for the discovery of bioactive peptides.
Numerical model of beam-to-column composite connection between slim floor system and composite column

The slim floor system has been used mainly due to the structural and constructive advantages of it, such as the capacity to overcome large spans with the low height of the composite floor system. There is a lack of finite element modelling researches of composite connections between the slim floor system and columns, especially with the concrete infilled steel tube columns. This paper presents the numerical approach based on the solid modelling, for the simulation of the nonlinear structural behavior of composite connection between partially encased composite beam and concrete infilled steel tube column; in this model, the composite beam represents the slim floor. The ABAQUS finite element code was used to investigate the behavior of composite connection that consists of a shear steel plate and negative reinforcement of the composite slab. In this paper, the authors discusses the procedures to the numerical model construction including finite elements and boundary conditions. Besides, the influence of stress-strain relationships for concrete and steel and the parameters that defines each model are presented and discussed, as well as the different steel to concrete interface conditions. Based on the results obtained, the effectiveness of the numerical model developed was verified against experimental results showing a good agreement response for the Moment vs. Rotation response, as well as the moment resistance of the composite connection.
