Authors: Barrios Sandoval Smith , Medina Mariño Ana Cecilia 
Published: November 2021

Este artículo da a conocer el avance de una investigación en el aula con enfoque cualitativo, que tiene como propósito desarrollar el razonamiento estadístico en niños de grado tercero de Educación Básica Primaria, mediante la estrategia de aprendizaje basado en proyectos (ABPr), a partir de un problema del contexto. En la revisión teórica y construcción de los antecedentes se reconoce la necesidad de los datos como base de la investigación estadística para comprender situaciones de la vida real. Se presenta a manera de reflexión, los resultados de la fase diagnóstica orientada a identificar los niveles iniciales de razonamiento estadístico que muestran los niños, con relación a la lectura e interpretación de tablas y gráficas estadísticas. La información analizada proviene de la aplicación de una prueba basada en una situación del contexto, un cuestionario utilizado por Ríos (2014) y una entrevista a docentes de la institución. Se encontró que los niños se ubican en los niveles de razonamiento estadístico idiosincrático y verbal según Garfield, Del Mas y Chance (1999). También se infieren algunos factores que inciden en este hallazgo, y al reconocerlos se corrobora que la estrategia planteada puede contribuir a mejorar el pensamiento aleatorio.

Published: November 2021

Abstract
This study aims the effects of land use changes on the carbon storage capacity and some soil properties of The Sultan Marshes was partially drained during the middle of the last century and converted to other land uses. Undisturbed soil sampling was performed in different land use types (rangelands, shrubs, marsh, agriculture, and dried lake area) in the wetland area at depths of 0-50 cm, and soil organic carbon (SOC), bulk density, and carbon stocks of soils for each land use type were calculated at 10 cm soil depth levels. Furthermore, disturbed soil samples were taken at two soil depths (0-20 cm and 20-40 cm), and the particle size distribution, pH, electrical conductivity (EC), aggregate stability and dispersion ratio (DR) properties of the soils were analyzed. Data were processed using ANOVA, Duncan’s test, and Pearson’s correlation analysis. The soil properties affected by land use change were SOC, carbon stock, pH, EC, aggregate stability, clay, silt, sand contents, and bulk density. SOC and carbon stocks were high in rangeland, marsh, and shrub land, while they were low in agriculture and drained lake areas. As the soil depth increased, SOC and carbon stock decreased. The organic carbon content of the soils exhibited positive relationships with aggregate stability, clay, and carbon stock, while it showed a negative correlation with bulk density, pH, and DR. The results showed that the drainage and conversion of the wetland caused a significant decrease in the carbon contents of the soils.

Published: November 2021

Abstract
This work includes the exploitation of laboratory-assembled SPR technique for the application of gas sensor at room temperature. The refractive index change at the interface of ZnO/Polypyrrole with adsorption of gases (NO2 and NH3) is the basis of SPR gas sensor. The theoretical simulations were done to find out the optimum thickness of ZnO and Polypyrrole composite films for sharp SPR reflectance values. Theoretical SPR curves obtained by changing the value of thickness of Gold nanoparticles film and incident wavelength are also presented in the manuscript. Experimental studies were done to validate the theoretical studies and discussion were done about the interaction of NH3 gas with prism/Au/ZnO/Polypyrrole system. Here, ZnO/Polypyrrole multilayer structure is the sensing layer to develop highly efficient SPR based NH3 gas sensor. The outcome of these results validate the significance of SPR technique for application of interaction of surface adsorbed analytes, with the interface of dielectrics and sensing material.

Abstract
Background

Malnutrition is considered to be a major public health challenge, which is associated with a range of health issues, including childhood stunting. Stunting is a reliable and well-recognized indicator of chronic childhood malnutrition. The objective of this study is to determine the effects of parental education and wealth on different specification of stunting among 17490 children below five years of age in Bangladesh.
Methods

Correlates of child stunting were examined using data generated by a cross-sectional cluster survey conducted in Bangladesh in 2019. The data includes a total of 17490 children (aged < 5 years) from 64400 households. Multiple logistic regressions were used to determine the risk factors associated with child stunting and severe stunting.
Results

The prevalence of stunting and severe stunting for children was 25.96% and 7.97%, respectively. Children aged 24 to <36 months [Odds Ratio (OR) = 2.65, 95% CI: 2.30, 3.05] and aged 36 to <48 months [OR = 2.33, 95% CI: 2.02, 2.69] had more risk of stunting compared to the children aged <6 months. Children from Sylhet division had the greatest risk of stunting of all the eight divisions [OR = 1.26, 95% CI: 1.09, 1.46]. Children of secondary complete or higher educated mothers were less likely to develop stunting [OR = 0.66, 95% CI: 0.56, 0.79] compared with children of mothers having no education at all. Similarly, children of secondary complete or higher educated father [OR = 0.74, 95% CI: 0.63, 0.87] were found to have lower risk of stunting compared with children whose father hadn’t any education. Substantially lower risk of stunting was observed among children whose mother and father both completed secondary education or above [OR = 0.59, 95% CI: 0.52, 0.69]. Children from richest households [OR = 0.49, 95% CI: 0.41, 0.58] had 51 % smaller odds on stunting compared to children from poorest families.
Conclusions

After controlling for socioeconomic and demographic factors, parental education and household position in wealth index were found as to be the most important determinants of child stunting in Bangladesh.
Stable C and N isotope analysis of human dental remains retrieved from an ancient well at Ajnala (Punjab, India): Assessment of Dietary status and geographic affiliations

Published: November 2021

Abstract
Stable isotope analysis of biogenic tissues like tooth and bone has become a widely recognized and increasingly important method for provenance of human remains, particularly in bio-archaeological and forensic investigations. Establishing the dietary status and identity of unknown human skeletal remains retrieved from forensic anthropological contexts is a challenging task. Thousands of unknown human osseous remains along with the personalized contextual items, reportedly belonging to 282 Indian soldiers killed in 1857, were excavated non-scientifically from an abandoned well at Ajnala (Amritsar, India). In present study, the isotopic concentrations of carbon (C) and nitrogen (N) were estimated from the dentine collagen extracted from 21 first molars to provide information about the geographic affinity and dietary status of the individuals killed in Ajnala. As diagenesis affects bone more severely than enamel or dentine due to increased porosity of the former, so teeth were preferred to bones for stable isotope analysis in present study. The literature supported C: N range of 2.8-3.6 was considered as cut-off for the well-preserved collagen and the samples with values outside this range were considered to be altered or contaminated with non-collagenous materials. The interpretation of the obtained isotope values from Ajnala teeth samples indicated the consumption of C3/C4 mixed diet (though some samples showing marine diet) by the victims which supported the previous observations about the dietary status of Ajnala victims estimated from prevalence of various dental pathologies. Though C and N isotopes are generally not the best indicators of geographic origin, they can be used to for the purpose only if they show different dietary inputs of C3 and C4 plants. Present study results provided scientific confirmation to the written historical accounts that Ajnala skeletal remains belonged to the individuals belonging to the Indian states of Awadh (north-eastern Uttar Pradesh), Bihar and Bengal and some norteastern states.

Abstract
A zero-knowledge decision making (ZKDM) method is proposed, and checked for correctness. For a certainkind of decision event, the decision maker does not know the internal mechanism and knowledge informationof the decision event. By defining the feature points and feature sets of the selection branches of the decisionevent, the characteristic moments of the system are constructed and the correct branch is obtained. It is observedthat the cases of arriving at the correct choice based on the ZKDM method have a certain universality. Theeffective mechanism of the ZKDM method may be related to the fact that the designers of decision events usuallydetermine the correct selection branch first, before changing it to design other branches. A questionnaire surveyof 279 respondents revealed that more than half of them adopted such a design idea. Furthermore, a separatequestionnaire survey of 465 decision-makers, reveal that 19.14% of the respondents clearly adopted ZKDM.

Abstract
Freeze-thaw cycles (FTCs) are an important element of mid and high latitude ecosystems, and significantly influence soil physicochemical properties and microbial activities in the soil active layers. With the global warming, the effects of FTCs on the dissolved organic carbon (DOC) concentration and soil enzyme activity of different types of soil were still uncertain. In this study, soil of undisturbed Deyeuxia angustifolia wetland (UDAW), disturbed Deyeuxia angustifolia wetland (DDAW) and rice paddy field (RP) from three soil layers of (0–10, 10–20 and 20–30 cm) in Sanjiang Plain, Northeast China, were collected, and then subjected to various FTCs with a large (10 to -10℃) and a small (5 to -5℃) amplitudes, respectively. The results indicated that FTCs increased the soil DOC concentration but reduced the concentration of MBC and activities of cellulase, invertase and catalase. Increase in the freeze-thaw frequency, resulted in the DOC concentration increasing initially and then decreasing, and the MBC concentration and soil enzyme activities were opposite. The DOC concentration increment resulting from the freeze-thaw effects was different across different layers and soil type: as the soil depth increased, the average DOC increments decreased, and the average DOC increments varied across different soil types: UDAW > DDAW > RP. The average MBC concentration and soil enzyme activity decreased from 0-10 cm > 10-20 cm > 20-30 cm soil depth; MBC concentration and soil enzyme activities varied across the different soil types: UDAW > DDAW > RP. The freeze-thaw amplitude and soil moisture content interaction had an effect on soil active organic carbon fractions and enzymatic activity. Small amplitude FTCs and higher water content had the greatest effect on DOC concentration, while larger amplitude and higher water content had the greatest effect on MBC concentration and enzymatic activity. In wetland soil, the significant correlations between active organic carbon fractions and enzyme activities indicate that the increased DOC by FTCs plays an important role in soil microbes and enzyme activities. However, active organic carbon fractions and enzyme activities had little correlation in RP, indicating that FTCs has more influence on wetland than farmland.

Published: November 2021

Abstract
Background: Fatty acid composition and content affect rapeseed oil quality. Fatty acid synthesis-related genes in rapeseed have been studied globally by researchers. Nevertheless, rapeseed oil is mainly composed of seven different fatty acids, and each fatty acid was regulated by different genes, furthermore different fatty acid contents affect each other, which needs continuous and in-depth research to obtain more clear results.Results: In this paper, broad-scale miRNA expression profiles were constructed and 21 differentially expressed miRNAs were detected. GO enrichment analysis showed that most up-regulated proteins were involved in transcription factor activity and catalytic activity. KEGG pathway enrichment analysis indicated that 20 pathways involving 36 target genes were enriched, of which the bna00592 pathway may be involved in fatty acid metabolism. The results were verified using a Quantitative Real-time PCR (RT-PCR) analysis, and it was found that the target gene of bna-miR156b>c>g was the OPR (12-oxo-phytodienoic acid reductase). Four copies of OPR gene were found, and the over-expression vectors (pCAMBIA1300-35s-OPR and pCAMBIA1300-RNAi-OPR) were constructed to verify their functions. In T1 and T2 plants, OPR-OE (OPR Over-Expression strain) significantly increased linoleic acid content (T1 12.56%, T2 7.185%) and OPRi (OPRi RNA-interference strain) decreased linoleic acid content (T1 5.98%, T2 0.86%).Conclusions: This is the first study to provide four copies of the OPR gene that regulates LA metabolism, can be used for the molecular mechanism of LA and optimizing fatty acid profiles in oilseed for breeding programs.

Published: November 2021

Abstract
Background: Whether it is possible to perform morphological evaluation of functional tricuspid regurgitation (FTR) on contrast-enhanced computed tomography (CT) was examined by evaluating the relationships between the parameters measured by contrast-enhanced CT and TR severity on transthoracic echocardiography.Methods: Fifty patients underwent contrast-enhanced CT. Tricuspid annulus area (TAA), tricuspid annulus circumference (TAC), right ventricular volume (RVV), and the distances between the tips and bases of the papillary muscles were measured on contrast-enhanced CT in diastole and systole. Fifty cases were divided into 34 in the TR ≤ mild group (none TR: 3 cases, trivial TR: 24 cases, mild TR: 7 cases), and 16 in the TR ≥ moderate group (moderate TR: 8 cases, severe TR: 8 cases) using the TR grade measured by transthoracic echocardiography, and then differences between the groups were examined.Results: Significant differences were found in TAA, TAC, and RVV (p<0.01) and the distances between the tips of the anterior and posterior papillary muscles (p<0.05) in both diastole and systole. Since the septal papillary muscle could not be identified in 18 cases (36.0%), only the distance between the anterior and posterior papillary muscles was measurable in all cases. On subgroup analysis, risk factors for FTR ≥ moderate were evaluated by multiple logistic regression analysis. The risk factors identified in the multivariable risk factor analysis were diastolic RVV (odds ratio 1.083 [95% confidence interval 1.029-1.139]) and systolic RVV (odds ratio 0.951 [95% confidence interval 0.906-0.997 ]).Conclusions: TAA, TAC, RVV, and the distance between the tips of the anterior and posterior papillary muscles measured on contrast-enhanced CT were shown to be significantly increased in the TR ≥ moderate group. Detailed morphological assessment of FTR is possible by contrast-enhanced CT.
