The Effectiveness of Virtual Reality in Mathematics for SPLDV Material

The lack of learning media and teacher creativity in implementing mathematics learning results in a lack of students' understanding and enthusiasm in learning mathematics. This research aims to analyze the design, feasibility, effectiveness and response of teachers and students in implementing virtual reality learning based on case-based learning in class VIII mathematics subjects. The research uses the Dick and Carey development model. The research subjects consisted of two content experts, one instructional design expert, one learning media expert, three individual test students, nine small group test students, and thirty-two field test students. The data collection methods used were interviews, questionnaires, tests and documentation. The data analysis techniques used are quantitative descriptive analysis, inferential statistical analysis (t-test), and N-Gain test. The content expert test results showed very high validity based on Gregory's validity. The expert test found, the score percentage is considered very good. Based on the t-test calculation, the significance value (Sig. 2-tailed) of 0.000 is smaller than 0.05 (p > 0.05), rejecting the null hypothesis (H0) and accepting the alternative hypothesis (Ha). So, it can be concluded that there is a significant difference in learning outcomes before and after using virtual reality based on case-based learning. The N-Gain calculation produces a score of 0.741, which indicates a high category so it can be concluded that the use of virtual reality learning based on case-based learning is effective in improving student learning outcomes in class VIII mathematics subjects.
Facilitators and barriers for retention of migrant students in Chile: experiences of four schools in Valparaíso

: The increase in the migrant population in Chilean schools has posed significant challenges for the education system. Although policies for promoting their integration have made progress, these students present a higher dropout rate than their local peers. This study aims to define the socioeducational facilitators and barriers involved in the completion of compulsory schooling by migrant students from the perspective of educational agents. For this purpose, using a qualitative methodology, 47 interviews were conducted with the management staff, support professionals and teachers from 4 schools in the Valparaíso region (Chile). The results indicate the existence of factors at the individual, social and family, and educational community levels that influence the retention of the migrant students from the Chilean schools studied. As a conclusion, despite several protective factors, this population is more vulnerable and prone to school dropout. Therefore, the design and
Efficacy of imazethapyr and other herbicides on weed growth and yield of kharif blackgram

A two year field experiment was conducted during the the kharif season of 2014 and 2015 at Agricultural Farm, Institute of Agriculture, Visva-Bharati, Sriniketan, West Bengal, with blackgram variety ‘WBU-108’ to study the effect of imazethapyr and other herbicides on weed growth, productivity and economics of kharif blackgram. The experiment was laid out in a randomized block design with three replications and eight treatments. From the investigation it revealed that Digitaria sanguinalis among the grasses; Cyperus iria among the sedges and Ludwigia parviflora and Croton bonplandianum among the broadleaved weeds were predominant throughout the cropping period. Higher doses of imazethapyr (75, 100 and 125 g ha-1) applied at 20 DAS effectively controlled the grasses, broadleaved and sedges in blackgram at 45 DAS. Yield reduction due to weed competition was to the extent of 26-29% in kharif blackgram. Lower values of weed density, total weed dry weight, weed index and higher values of weed control efficiency, seed yield, net return and return per rupee invested were registered with application of imazethapyr at 75 g ha-1 at 20 DAS which was at par with by imazethapyr at 100 g ha-1 at 20 DAS. These treatments may be recommended for managing complex weed flora and obtaining higher yield and net return of kharif blackgram in the lateritic belt of West Bengal, India.
Ebbulitive flux of early-diagenetic methane from recent freshwater sediments in lake Nowa Cerekiew (SW Poland)

Strumien ebulicji wczesnodiagenetycznego metanu ze wspolczesnych osadow slodkowodnych jeziora Nowa Cerekiew (SW Polska) Observations concerning ebullition of methane from freshwater lake sediments, at depths of 2.8 m and 4.2 m, and occasionally at of 4.5, 5.5 and 11 m have been carried out. A closed type, artificial lake Nowa Cerekiew (SW Poland) about 30 years old, with organic rich sediments 25 cm thick, was selected for this study. Collection of ebulliting gases has been carried out using bottom-situated funnel-shape collectors with connected flasks (exchanged by scubadiving). The observations have been carried out continuously between 1992 to 1996, including winters when the lake was covered by ice. Concentration of methane in ebullition varied from 9.06% (winter) to 76.82% (early summer). Ebullition (expressed as the mean diurnal production of carbon trapped into the collectors in the form of bubbles of methane naturally released from 1 m3 of the most productive 25 cm uppermost layer of the sediments (C-CH4 x day(-1) x m(-3)) varied from about 100 mg (C-CH4 x day(-1) x m(-3)) to near zero during winter. In contrast to the deeper sampling station (4.2 m), the ebullitive methane from the shallower depth (2.8 m) showed substantial seasonal variation in the δ13C(CH4) value, from -63.12‰ during winter to -52.46‰ during summer. The global freshwater lake ebullitive CH4 flux has been roughly estimated at about 5x10(8)g(C-CH4)xy(-1). The observed enhanced ebullitive CH4 flux during summer and the higher δ13C(CH4) value during early summer are apparently a result of: (i) efficient decomposition of the fresh organic matter, deposited into the anoxic zone on the sediment surface, and consequently a relatively more enhanced acetic acid pathway and, (ii) increased bacterial activity at higher temperature. The lower δ13C(CH4) value in the deeper sampling station during summer may be a result of: (i) longer time for the organic matter to sink to greater depth and consequently there is greater decomposition of easily degradable compounds which are the main precursors of acetate, (ii) perhaps an increase of bioavailable DIC, due to elevated pressures and lower temperatures at greater depths, enhancing the CO2 pathway, and (iii) limited diffusion of isotopically depleted carbon-bearing compounds from greater depths.
Bayesian Optimization Based Neural Architecture Search for Classification of Gases/Odors Mixtures

This work demonstrates the potential of the proposed Bayesian optimization (BO). It is based on neural architecture search (NAS) for the classification of gases/odors for datasets of diverse applications and complexities in terms of the number of analytes, features, and datapoints. NAS is an aspect of automated machine learning (AutoML), which explores and exploits a bounded search space of hyper-parameters to obtain optimal neural network (NN) architectures. Herein, Gaussian distribution has been used to model the search space as a probabilistic distribution and BO has been used as an acquisition function to guide the search process in the modeled search space. NAS has been implemented by iteratively minimizing the loss function i.e., categorical cross entropy (CE). Furthermore, the excellent classification accuracies obtained, in hazardous gas detection, beef quality examination, and vehicular exhaust monitoring are calculated to be 100%, 99.68%, and 99.46% respectively. The innovative approach establishes the robustness of the proposed BO-aided NAS in obtaining optimal gases/odors classification for diverse gaseous mixture datasets.
ENSO Precipitation and Temperature Forecasts in the North American Multimodel Ensemble: Composite Analysis and Validation

AbstractIn this study, precipitation and temperature forecasts during El Nino–Southern Oscillation (ENSO) events are examined in six models in the North American Multimodel Ensemble (NMME), including the CFSv2, CanCM3, CanCM4, the Forecast-Oriented Low Ocean Resolution (FLOR) version of GFDL CM2.5, GEOS-5, and CCSM4 models, by comparing the model-based ENSO composites to the observed. The composite analysis is conducted using the 1982–2010 hindcasts for each of the six models with selected ENSO episodes based on the seasonal oceanic Nino index just prior to the date the forecasts were initiated. Two types of composites are constructed over the North American continent: one based on mean precipitation and temperature anomalies and the other based on their probability of occurrence in a tercile-based system. The composites apply to monthly mean conditions in November, December, January, February, and March as well as to the 5-month aggregates representing the winter conditions. For anomaly composites, the a.
Cartographie De L’erosion Qualitative Des Sols Du Bassin Versant De L’aoudour (Rif-Maroc)

The Aoudour watershed located in the northwest of Morocco and spreads over an area of approximately 1000 km2, and occupying the northeastern part of the Ouergha basin contently experiencing the effects of severe water erosion caused by the interaction of several natural factors such as the amount and aggressiveness of rainfall, plenty of steep slopes, low vegetation density and also the dominance of friable land. The Aoudour watershed also undergoes a human action that makes it very vulnerable to environment erosion, the degradation of the vegetation cover in recent decades and also by poor farming techniques. PAP / RAC is a method of qualitative study of water erosion that can prioritize the surface of a watershed in separate units according to its vulnerability to erosion. The method consists of a descriptive and predictive mapping in relation to the identification; evaluation and integration of basic physical factors such as slope, lithology and / or soils and vegetation cover, with the aim of establish initial assumptions about the risk of erosion. The use of remote sensing and GIS tools enabled us creating and overlying of thematic maps, executing speedily the cartographic works and, processing of databases.
Plant Economy and Land Use in Middle Egypt during the Late Antique/Early Islamic Period: Archaeobotanical Analysis of Mud Bricks and Mud Plasters from the Area of Dayr al-Barshā

The current study presents the archaeobotanical analysis of mud bricks and plasters from the Coptic occupation (from ca 400 to ca 800 AD) from several localities in the vicinity of Dayr al-Barshā, Middle Egypt. The data set presented comes from three locations, i.e., Dayr Abū Hinnis (reused quarries), Dayr al-Barshā and al-Shaykh Sa‛īd (reused Pharaonic tombs) and consists mainly of desiccated plant material retrieved from 32 samples. The chaff and particularly rachis fragments of main cereal crops characteristic for the period of study, barley and free threshing wheat, dominate the archaeobotanical finds. Apart from these, there are rather numerous remains of radish, which are interpreted as by-products of oil-production. In most cases, one of these three species is the dominant tempering material found in the studied samples. The plant assemblages from mud bricks and plasters compared with those from settlement contexts in the same area show good potential for obtaining information on the principal crops for the study area. A wide variety of non-cultivated plants found helps to reconstruct the habitats exploited in the areas surrounding the site during the period studied. The botanical analysis of dung pellets found in some mud bricks permits an estimation of the contribution of animal dung to the variety of plant taxa identified.
Noisy condition and three-point shot performance in skilled basketball players: the limited effect of self-talk

In modern basketball, the three-point shot plays an important tactical role. Basketball players often face the distraction from audience and opponents, necessitating psychological skill to maintain their performance. The study examined the effects of self-talk interventions on the three-point shot performance under quiet and noisy conditions. It involved 42 national second-level basketball players and used a 2 (Condition: quiet condition, noisy condition) × 3 (Intervention: control group, motivational self-talk, instructional self-talk) mixed design to investigate the performance of the static and dynamic three-point shots tasks. The results revealed that the static three-point shot score was significantly lower in noisy condition compared to quiet condition (p = 0.016), while the main effect of Intervention and the interaction effect of Condition × Intervention were not significant. Post-hoc analysis indicated that only the control group showed significantly lower scores in the noisy condition (p = 0.043). For the dynamic three-point shots performance, there were no significant main effects of Intervention or Condition, nor any significant interaction effect between Condition and Intervention. In conclusion, noise distraction negatively affects the static three-point shots task, and although self-talk interventions can mitigate such negative effects, their effectiveness is limited for dynamic three-point shots task with high physical demands.
Sex Differences in the Relationship between Personal, Psychological and Biochemical Factors with Blood Pressure in a Healthy Adult Mexican Population: A Cross-Sectional Study

Hypertension is one of the main risk factors related to cardiovascular mortality, being the levels of blood pressure (BP) related to a variety of personal, anthropometric, biochemical and psychological variables; however, the study evaluating the association of all these factors in systolic blood pressure (SBP) and diastolic blood pressure (DBP) in a sample of relatively healthy subjects has not been performed. The aim of the study was to determine the main variables associated with SBP and DPB in a sample of relatively healthy subjects. A total of 171 participants were included, in which personal, anthropometric, positive and negative psychological variables and biochemical variables were measured. We observed that men showed higher levels of SBP and DBP than women, with more differences for SBP. Among the biochemical factors and SBP, we found that albumin and monocytes were positively correlated with it, while potassium, phosphorus and eosinophils were negatively correlated with it. Additionally, schooling was a constant variable negatively correlated with SBP in all samples (global, men and women). Among psychological variables, we observed that emotional perception was negatively correlated with SBP in men’s and women’s samples, while autonomy was positively correlated with SBP in the men’s sample; however, their association was less when compared with the personal and biochemical variables included in the multivariate model. With regard to DBP, we observed that the biochemical variables, hemoglobin, sodium, uric acid and glucose, were positively correlated with DBP in the global sample, while chloride and BUN were negatively correlated with it. In addition, many personal and behavioral variables, including BMI, age and smoking consumption frequency, also correlated with DBP in the global sample. In conclusion, BP is affected by different factors, and these affect each sex differently.

Purpose: To describe children with 22q11.2 deletion syndrome functioning from a biopsychosocial perspective, focusing on the impact of childrens health condition from domains to the International Classification of Functioning, Disability and Health (ICF). Methods: A descriptive, cross-sectional case series study with 22q11.2del children. A questionnaire with an ICF checklist for 22q11.2del was completed using a structured interview. The Test of Childhood Language ABFW was used to fill in vocabulary, fluency and language pragmatics questions. The Wechsler Abbreviated Scale of Intelligence (WASI) was used to determine Intelligence Quotient (IQ). Results: Seven participants from 7 to 12 years old, presented some level of IQ impairment. Observed that 22q11.2del children experience significant intellectual, cognitive and speech impairment across ICF Body Function domains. Impairment related to nose and pharynx were found in only one patient. The most relevant categories considered limitations in Activity and Participation component were pertained to producing nonverbal messages, communication, handling stress and social interaction. Family, health professionals and acquaintances were perceived as facilitators in the component Environmental Factors. Conclusion: Children with 22q11.2del have their functioning affected by aspects that go beyond medical diagnosis. A checklist base on ICF for functional profile can contribute to incorporate a biopsychosocial approach.
Volume Density Structure of the Central Molecular Zone NGC 253 through ALCHEMI Excitation Analysis

We present a spatially resolved excitation analysis for the central molecular zone (CMZ) of the starburst galaxy NGC 253 using the data from the Atacama Large Millimeter/submillimeter Array Comprehensive High-resolution Extragalactic Molecular Inventory, whereby we explore parameters distinguishing NGC 253 from the quiescent Milky Way’s Galactic center (GC). Non-LTE analyses employing a hierarchical Bayesian framework are applied to Band 3–7 transitions from nine molecular species to delineate the position–position–velocity distributions of column density ( NH2 ), volume density ( nH2 ), and temperature (T kin) at 27 pc resolution. Two distinct components are detected: a low-density component with (nH2,Tkin)∼(103.3cm−3,85K) and a high-density component with (nH2,Tkin)∼(104.4cm−3,110K) , separated at nH2∼103.8cm−3 . NGC 253 has ∼10 times the high-density gas mass and ∼3 times the dense-gas mass fraction of the GC. These properties are consistent with their HCN/CO ratio but cannot alone explain the factor of ∼30 difference in their star formation efficiencies (SFEs), contradicting the dense-gas mass to star formation rate scaling law. The nH2 histogram toward NGC 253 exhibits a shallow declining slope up to nH2∼106cm−3 , while that of the GC steeply drops in nH2≳104.5cm−3 and vanishes at 105 cm−3. Their dense-gas mass fraction ratio becomes consistent with their SFEs when the threshold nH2 for the dense gas is taken at ∼104.2−4.6 cm−3. The rich abundance of gas above this density range in the NGC 253 CMZ, or its scarcity in the GC, is likely to be the critical difference characterizing the contrasting star formation in the centers of the two galaxies.
Study on feasibility of CORS application in surface movement deformation monitoring in mining areas

CORS has been widely established in China and abroad, and can be used in geodetic measuring, coordinate system retaining and surveying and mapping of city. However, some issues (stability of base stations, influence of survey precision on horizontal and vertical extension, et al) are still unsolved in Surface Movement Deformation Monitoring in Mining Areas. Based on the CORS, a method and flow for data processing and stability analysis of deformation monitoring network was proposed. Using rank defect free network adjustment, a robust estimation with minimum of first order norm of displacement component was offered to determine displacement of relative stability. The strategy can resolve the confirmation of robust iterative weights and the effects of different reference models. Displacement significance was tested with the normality method. Finally, according to this method , datum of GPS deformation monitoring in Mining Areas in Datong were calculated and preliminarily proved that this method was feasible and effective, providing a new monitoring methodologies terrain monitoring in mining areas.
Study of sodium and potassium changes in term neonates receiving phototherapy

Background: Neonatal Hyperbilirubinemia (NH) is the commonest abnormal physical finding during the first week of life and also the most common cause for readmission during the early neonatal period is a cause of concern for the parents as well as for the Pediatricians. Hence appropriate management of Neonatal Hyperbilirubinemia is of paramount importance. Phototherapy plays a significant role in prevention and treatment of hyperbilirubinemia. However, this treatment modality may itself result in inherent complications. The present study was carried out with the objective of evaluating the sodium and potassium changes in neonates receiving phototherapy for neonatal hyperbilirubinemia.Methods: A prospective hospital based observational comparative study conducted on 96 eligible term neonates admitted in the neonatal intensive care unit receiving phototherapy at a teaching Hospital from October 1st to December 31st 2018. A predesigned proforma has aided the enrolment of new-borns into the study according to AAP guidelines. Serum bilirubin, sodium and potassium were determined before and after termination of phototherapy. The first samples were considered as controls. A comparative study was made between before and after phototherapy groups to determine the incidence of sodium and potassium changes.Results: The study group included 96 term neonates that were managed with phototherapy. Incidence of low birth weight babies was 21.9%. Mean birth weight and gestational age was 2.76±0.38 kg and of 38.34±0.88 weeks respectively. Mean duration of phototherapy was 38.48±09.34 hours. The incidence of Sodium and potassium changes were found to be statistically significant after phototherapy (p<0.01) but neonates didn’t develop any signs of hyponatremia and hypokalemia.Conclusions: The study shows that neonates undergoing phototherapy are at a higher risk of sodium and potassium changes. This risk is greater in LBW babies and hence this group of babies should be closely monitored for changes in sodium, potassium and should be managed accordingly.
Impact of occupational heat exposure on selected haematological parameters of bakery workers: A comprehensive study in Ilorin, Kwara State

The Occupational Health and Safety Administration has identified indoor industries at risk of experiencing heat-related illnesses due to the presence of heat-generating appliances; these include bakeries, kitchens, laundries, and furnaces. This study aimed to assess the effects of heat stress on haematological parameters and erythrocyte sedimentation rates (ESR) of bakery workers in Ilorin, Kwara State. It was a cross-sectional study, involving laboratory analysis, which lasted for 3 months. A total of 60 Male and female bakery workers aged between 18 and 65 years with 1 or more years of working experience were recruited for this study. Full blood count estimation was carried out using haematological analyzer (Sysmex-2000) and the ESR was carried out using the Westergren method in the Haematology unit, Kwara State University, Malete. Results were analyzed using SPSS version 20. This study found the bakery workers to have low ESR (2.13 ± 1.28) compared to (10.05 ± 4.95) of the control, the RBC was high (6.708 ± 2.08) compared to (5.46 ± 1.12) of the control group. TWBC was also found to be high (7.425 ± 1.74) compared to (6.95 ± 2.49) of the control population. Findings from this study concluded that working under high temperatures negatively affected the health of bakery workers with reports of heat stress-related symptoms and also affected ESR and haematological parameters. A comprehensive and effective national occupational health and safety program that includes relevant policies, decrees, and proper enforcement is needed to ensure the worker’s safety and health both in the formal and the fast-growing informal sectors.
