Artificial neural network for gender determination using mandibular morphometric parameters: A comparative retrospective study

Abstract Gender determination is of paramount importance in order to identify the diseased in cases of mass disasters and accidents and to resolve all medico-legal issues in cases of violence. Skeletal bones are the strongest bones in the body and they play a crucial role in identifying a person’s gender. ANN is a relatively new technology, is fast emerging as a better prediction model for gender when used with skeletal bones like the femur. Prior studies have extensively used discriminant analysis, logistic regression and other similar statistical tools to understand the role of the mandible and its efficacy in gender determination. This study uses Artificial Neural Networks (ANN) for gender determination and compares results thus obtained with logistic regression and discriminant analysis using mandibular parameters as inputs. Digital panoramic radiographs were used to measure the mandible of 509 individuals. Six linear parameters and one angular parameter of each individual were obtained. Logistic Regression, Discriminant Analysis, and ANN analysis were performed on these parameters. The discriminant analysis had an overall accuracy of 69.1%, logistic regression showed an accuracy of 69.9% and ANN exhibited a higher accuracy of 75%. The results revealed that ANN is a good gender prediction tool that can be applied in the field of forensic sciences for near accurate results. Its application is promising as it automates and eases the method of identifying unknown gender or age with minimal errors.
Thermal Softening and Cell Wall Chemistry of Plantation-Grown Palasan (Calamus merrillii Becc) Canes

Softening temperature of plantation-grown palasan (Calamus merrillii Becc.) cane was measured. The chemical constituents of its cell wall were likewise determined using standard procedures used in wood. Softening temperature was about 84.44°C to 86.37°C which is within the range of wild palasan canes and it was unaffected by the origin of the sample. Holocellulose content was about 64.54% 75.38%, in which 37.08% 48.08% is cellulose and 23.09 % 36.43% is hemicellulose. Lignin constitutes approximately 22.16% 32.10% of the wall. Relationship between the chemical constituents and softening temperature was not detected. The fabricated thermomechanical analyzer was limited to the detection of macrostrains occurring in the sample and could not detect deflection down to the microstrain level where these individual chemical constituents normally move. Nonetheless, the device was able to prove that plantation-grown palasan canes have the same softening temperature as that of wild palasan canes. This material could be converted into furniture of the same quality as that of wild rattan canes. This confirms the utility of plantation-grown palasan canes to the rattan furniture Industry.

The Effect of Spinach Powder and Egg-Shell Powder on Physicochemical and Edible Qualities of Gluten-Free Cake

ORIGINAL ARTICLE Background: Replacement of the gluten is one of the challenging issues in the food industry, since producing nutritious and functionally acceptable glutenfree foods is difficult. The cake is a cereal-based product that attracts the consumers due to its various flavors, long shelf-life, and relatively low cost. Considering the competition in markets and the increased demand for functional and natural products, efforts have been made to improve nutritional and functional properties of the cakes by modifying their nutritional composition. Methods: In this research, the effect of spinach powder (0-30 %) and egg-shell powder (0-7%) was evaluated on physical characteristics (density, porosity, color, texture properties) and functional properties (Total phenol, DPPH, Ash, moisture content, crude fiber, Mineral content) of gluten free-cake. Results: The results indicated that increasing spinach powder reduced L * value, a * value, porosity, and hardness, while it increased the moisture content, density, ash, mineral content, total phenol, antioxidant activity, total fiber, and overall acceptance. Increase of the egg-shell powder increased moisture content, a * value, total phenol and was decreased overall acceptance. On desirability function method, gluten-free cakes formulated with 11.78% of spinach powder and 4% of egg-shell powder had the most and desired physicochemical quality. Conclusion: Overall, the results indicated that spinach powder and eggshell powder could offer promising sources for improving the functional properties and acceptability of gluten-free cakes.
Strains of Spodoptera frugiperda (J.E.Smith) (Noctuidae) in the states of Paraná and São Paulo, Brazil

Two strains of Spodoptera frugiperda (J.E. Smith) were first described in the United States; in Brazil, in the states of Rio Grande do Sul, Mato Grosso, and western Parana they have also been reported. This study was aimed at identifying these strains in Norte Pioneiro and Campos Gerais, in the states of Parana and southwestern Sao Paulo. Larvae of S. frugiperda were collected in the cities of Ponta Grossa, Tibagi, Arapoti, and Wenceslau Braz in Parana, and in the city of Itabera, in Sao Paulo. PCR-RFLP genotyping of the COI gene was carried out using sixty-six specimens. Based on their electrophoretic pattern, 51 individuals were identified as corn strain, five as rice strain, and 10 as hybrids (Rice in MspI and Maize in SacI). Our findings indicate that both S. frugiperda strains are present the study areas.
Development of nano-crosslinked polyacrylonitrile ions exchanger particles for dye removal: kinetic, isotherm, and thermodynamic studies

Poly(acrylonitrile-co-divinylbenzene) nanoparticles (PAN) based adsorbents developed for the adsorption of methylene blue (MB) from contaminated water. Essential factors affecting the adsorption process such as MB concentration, adsorption time and adsorption temperatures have studied. A linear increment of the adsorption capacity recognized with the increase of the dye concentration up to 7 ppm, then leveling off was noticed. The adsorption capacity of both adsorbents increased linearly with adsorption time, and the equilibrium almost reached after 5 h. A negative impact of the adsorption temperature observed upon the adsorption capacity. Fitting the adsorption results with different kinetic models revealed that the adsorption of MB met with the pseudo-second-order kinetic model having higher R2 values; 0.9971 and 0.9945 for PAN and amidoxime modified polyacrylonitrile. Testing the diffusion mechanism of the MB adsorption process indicates that the film diffusion governs the rate-limiting process. The Freundlich isotherm model was found more favorable for the adsorption of MB. The thermodynamic parameters indicate the exothermic nature of the adsorption process. The best performance recognized at low temperatures.
Effect of post-etching cleaning methods on surface micromorphology and shear bond strength of composite resin cement to feldspathic ceramic blocks

Statement of the problem: Silica-based ceramics, such as feldspathic porcelain are widely introduced as laminate veneers and inlays/onlays due to their excellent esthetic properties. The success in achieving the right bonding protocol is the challenge which contributes to the restorations longevity.Objectives: This study aimed to evaluate the effect of post etching surface cleaning protocol on the surface micromorphology and shear bond strength of resin cement composite to feldspathic ceramic blocks.Materials and Methods: A total of sixty discs (fifty for the mechanical test and 5 for each scanning microscopic method) of feldspathic ceramic blocks (VITA MARKII) were prepared and etched with 9.5% hydrofluoric acid for 90 seconds the discs then randomly divided into five groups (N=10) HF not subjected to any cleaning step after HFl etching. The HHU group 37% phosphoric acid postetched for 30 seconds then immersed in ultrasonic bath for 5 minutes, the HHV group was postetched with 37% phosphoric acid for 30 seconds then vacuum dried, HV group was vacuum dried only. The HHUV group was postetched with 37% phosphoric acid for 30 seconds then immersed in ultrasonic bath for 5 minutes then vacuum dried. The surface of each disc was scanned for examination of the surface topography before and after surface treatments. Two different imaging techniques were used: scanning electron microscopy and laser confocal microscopy. Adhesive resin cement (NEXUS 3) was directly bonded to each ceramic disc using a special device providing the same thickness of the cement layer. All the samples were then subjected to shear bond strength tests. Statistical significances between groups were analyzed using one-way ANOVA and (SNK) multiple comparison tests.Results: The results of the shear bond strength showed that there is significant difference between (HF) group and both HV or HHV groups, while showed no significant differences with any other groups where the ultrasonic bath was used. Laser confocal microcopy 3D data analysis showed significant difference in the surface roughness depth between the groups what is subjected to Ultrasonic bath (HHUV and HHU) and the other three groups. the analysis shows significant difference as well between (HF group) and (HV and HHV groups). While was no significant difference between (HV and HHV) groups.Clinical implication Finding an exact protocol of post etching cleaning is of a big importance nowadays with the increased shifting towards the conservatism and esthetic dentistry and laminate veneers solutions which success depends mainly on the long term bonding strength.
The Proportion and Prognostic Significance of T-Regulatory Cells in Patients with Gynecological Cancers: A Systematic Review and Meta-Analysis

Objective: Multiple reports have described the proportion of T-regulatory cells (Tregs) in peripheral blood (PB) and tissues in patients with gynecological cancers (GCs) with controversial results. Thus, the aim of this study was to investigate the proportion of Tregs and its prognostic survival role in GCs patients. Methods: We performed a comprehensive search from database inception for all studies presenting changes of Tregs in GCs patients versus controls to evaluate the pooled standardized mean differences (SMD) with 95% confidence intervals (95% CI). And hazard ratios (HRs) with 95% CI were recorded if available to determine the prognostic significance of Tregs. Results: Totally, 22 studies were included. Compared with controls, GCs patients had a higher proportion of Tregs in PB (SMD = 2.32, 95% CI = 1.47 to 3.17, P = 0.000) as well as in tissues (SMD = 3.47, 95% CI = 0.77 to 6.18, P = 0.012). Furthermore, more significant elevated frequency of Tregs was observed in GCs patients with advanced stage than those in the early stage in both PB and tissues. However, no association was found between Tregs and survival of GCs patients with an HR of 1.34 (95% CI = 0.96 to 1.88, P = 0.09). Conclusions: Compared to controls, proportion of Tregs in PB and tissues was both higher among GCs patients, and it can be considered as a clinical biomarker for screening and prediction of clinical characteristics of GCs patients. But larger researches with rigorous design should be carried to explore the deep mechanisms of Tregs in GCs.

The Validity and Instructional Value of a Rubric for Evaluating Online Course Quality: An Empirical Study

This study investigated the validity and instructional value of a rubric developed to evaluate the quality of online courses offered at a midsized public university. This rubric was adapted from an online course quality rubric widely used in higher education, the Quality Matters rubric. We first examined the reliability and preliminary construct validity of the rubric using quality ratings for 202 online courses and eliminated twelve problematic items. We then examined the instructional value of the rubric by investigating causal relationships between 1) course quality scores, 2) online interactions between students, instructors, and content, and 3) student course performance (course passing rates). A path analysis model, using data from 121 online courses enrolling 5,240 students, showed that only rubric items related to learner engagement and interaction had a significant and positive effect on online interactions, while only student-content interaction significantly and positively influenced course passing rates.
Impact of Cinnamon and Cloves Extracts Incorporated in Fluoride Varnish Containing CPP-ACP on Microhardness and Color of Enamel

Objective: The current study aimed to evaluate the effects of methanolic extracts of Cinnamon and Cloves mixed with Fluoride Varnish Containing CPP-ACP (MI Varnish™) treatments on the enamel microhardness and color. Material and Methods: Forty enamel specimens obtained from twenty human impacted third molars were randomly divided into four groups (n = 10) according to surface treatment: (G1) MI Varnish™ mixed with methanolic extract of Cinnamon; (G2) MI Varnish™ mixed with methanolic extract of Cloves; (G3) MI Varnish™ mixed with methanolic extracts of Cinnamon and Cloves meanwhile (G4) MI Varnish™ alone. Specimens were subjected to pH cycling. Color (ΔE) and surface microhardness were measured for each specimen at base line, after demineralization and post treatment. Results: The highest microhardness values presented in MI Varnish alone (G4) and MI Varnish™ mixed with methanolic extracts of Cinnamon and Cloves (G3) without any significant difference between them, followed by MI Varnish™ mixed with methanolic extract of Cinnamon (G1), while the lowest hardness values were found in MI Varnish™ mixed with methanolic extract of Cloves (G2). There was an increase in ΔE3 values for all groups. Conclusions: Under the limitations of the current study, application of Cinnamon and Clove as herbal antibacterial medicaments does not affect enamel microhardness negatively when added with the MI paste at certain ratio. Meanwhile, unacceptable color changes of enamel surface are expected.
An investigation into translation students ' English reading comprehension skills and strategies : a cross-sectional study

The present study aimed at investigating different reading comprehension strategies applied by Iranian B.A students of translation while translating a text from English to Persian. In doing so, thirty-two students (sixteen sophomores and sixteen seniors) were given a text with a nearly high level of difficulty to be translated. This level of difficulty was doublechecked by two professors in advance. Each and every step taken during the process of translation was then tape-recorded and further placed in the classes of ‘general’ vs. ‘local’ reading comprehension strategies pointed out by Block (1992), which is based on thinkaloud protocols. The results of the Chi-Square tests indicated that there were statistically significant differences in terms of the frequencies of local strategies among the ‘higher’ vs. the ‘lower’ level of students. The findings also revealed that there were no statistically significant differences in using the general strategies among such students. © 2014 Elixir All rights reserved ARTICLE INF O Article h istory: Received: 28 June 2014; Received in revised form: 25 July 2014; Accepted: 6 August 2014;
The Affectively Extended Self

In this paper we suggest an understanding of the self within the conceptual framework of situated affectivity, proposing the notion of an affectively extended self and arguing that the construction, diachronic re-shaping and maintenance of the self is mediated first by affective interactions. We initially consider the different variations on the conception of the extended self that have been already proposed in the literature (Clark & Chalmers 1998; Heersmink 2017, 2018; Krueger 2018; Wilson, Lenart 2015). We then propose our alternative, contextualising it within the current debate on situated affectivity. While the idea that we exploit the external environment in order to manage our affective life is now rather widespread among philosophers (e.g. Colombetti & Krueger 2015, Piredda 2019), its potential consequences for and connections with the debate on the self remain underexplored. Drawing on James’ intuition of the “material self”, which clearly connects the self and the emotions in agency, and broadly envisioning an extension of the self beyond its organismic boundaries, we propose our pragmatist conception of the self: an affectively extended self that relies on affective artifacts and practices to construct its identity extended beyond skin and skull.
Massive MIMO-NOMA Networks With Imperfect SIC: Design and Fairness Enhancement

This paper addresses multi-user multi-cluster massive multiple-input-multiple-output (MIMO) systems with non-orthogonal multiple access (NOMA). Assuming the downlink mode, and taking into consideration the impact of imperfect successive interference cancellation (SIC), an in-depth analytical analysis is carried out, in which closed-form expressions for the outage probability and ergodic rates are derived. Subsequently, the power allocation coefficients of users within each sub-group are optimized to maximize fairness. The considered power optimization is simplified to a convex problem, which makes it possible to obtain the optimal solution via Karush-Kuhn-Tucker (KKT) conditions. Based on the achieved solution, we propose an iterative algorithm to provide fairness also among different sub-groups. Simulation results alongside with insightful discussions are provided to investigate the impact of imperfect SIC and demonstrate the fairness superiority of the proposed dynamic power allocation policies. For example, our results show that if the residual error propagation levels are high, the employment of orthogonal multiple access (OMA) is always preferable than NOMA. It is also shown that the proposed power allocation outperforms conventional massive MIMO-NOMA setups operating with fixed power allocation strategies in terms of outage probability.
Household-level drivers of dietary diversity in transitioning agricultural systems_ Evidence from the Greater Mekong Subregion

Over the past four decades, agricultural systems in the Greater Mekong Subregion (GMS) have largely evolved from a subsistence orientation toward commercial production, but the multi-faceted changes behind this evolution vary in substance and degree. Despite connoting economic progress, effects of these changes on household welfare indicators such as dietary diversity have been unclear. By taking a comprehensive view of the farm household, this study discerns the drivers of household dietary diversity in this transitional context by linking the Household Dietary Diversity Score (HDDS), as an indicator of dietary diversity, to key household characteristics, livelihood strategies and indicators of farm performance in three study sites in Cambodia, Laos and Vietnam. The Rural Household Multi-Indicator Survey (RHoMIS) tool, a combined survey and analysis platform, was employed to collect data from over 1300 farm households. HDDS is found to increase among the sites in a way that is roughly associated with their state of agricultural transition, though differing combinations of market orientation, specialisation, and intensification traits that describe such a transition suggest that the pathway to commercialisation, and dietary diversity, is not a linear one. Drivers of dietary diversity vary markedly between the sites. In the Laos site, HDDS is most closely correlated to a set of variables closely linked with agricultural transition, while in the Cambodia site it is associated more with other farm and household characteristics. In the Vietnam site, dietary diversity is correlated to the overall value of crop production. Findings point to the need to contextualise site-specific knowledge of linkages between dietary diversity and ongoing agricultural transition in the GMS, as well as policy and interventions seeking to improve dietary diversity in the face of such transition.
Evaluation of silver and copper oxide NANOPARTICLES release from different prosthetic materials incorporated with nanoparticles

The purpose of this study was to evaluate the amount of released of silver and copper oxide nanoparticles when they were incorporated in heat cured acrylic resin denture, chemical cured soft liner, and cream type adhesive.Material and methods: A total number of 240 samples were prepared, 80 denture base samples, 80 liner, and 80 adhesives, and 10 samples from each material were free from nanoparticles that act as a control. The remaining samples were divided into two groups: (Group I) contained denture base, liner and adhesive samples modified with copper-oxide nanoparticles concentration by (0.1%, 0.3%, and 0.5%, 10 sample each), and (Group II) has the same number of samples but modified with same silver nanoparticles concentrations. The samples were placed in distilled water for one week and the amount of release was measured by spectrophotometer. The recordings data were analyzed using Two-way repeated measures Analysis of Variance (ANOVA) to compare between the three groups as well as to study the effect of time within each group. Bonferroni’s post-hoc test was used for pair-wise comparisons. P< 0.05 was considered.Results: Release was higher in denture adhesive followed by denture liner and denture base respectively in the two groups. The amount of release increased with increasing nanoparticles concentration in denture base and adhesive but not in denture liner. There was no significant difference between Group I, and Group II.Conclusion: Nanoparticle release was affected by the type of prosthetic material, nanoparticle concentration, but not nanoparticles type.
The Effects of Anesthesiologist on Anxiety Level in Patients Undergoing In-Vitro-Fertilization Therapy

Background: In Vitro Fertilization (IVF) treatment is an assisted reproductive technique applied in infertile couples. According to World Health Organization reports, infertility affects 50 to 80 million women worldwide. The hopelessness of patients treated with IVF determines the severity of anxiety. Although anxiety is functional up to a certain level, higher preoperative anxiety levels have been associated with increased anesthetic requirement. In order to reduce the level of anxiety, patients should be prepared psychologically and pharmacologically for surgery. The aim of this study was to investigate the awareness of anesthesiologists about perioperative anxiety of patients undergoing surgery for IVF.
