The implementation of research activities in this paper is intended to provide an analysis related to the ability of students to reason mathematically in terms of self-regulated learning using qualitative methods and descriptive approaches. Data collection techniques will be obtained through filling out 6 test questions, 28 questionnaire statements, and interview activities. The subjects to be observed were carried out through a technique called purposive sampling so that 6 students were obtained which were divided into two students in each category. The datta will be arranged sequentially using data analysis technique consisting of data reduction, data presentation, and drawing conclusions. The results of the data found identify that students in the high self-regulated learning category have mathematical reasoning abilities as well. Furthermore, students in the medium categori have the ability to do moderate mathematical reasoning. Finally, students who are in the low category have low mathematical reasoning abilities. So based on the data above, it can be concluded that the higher the level of self-regulated learning. The less likely it is to make mistakes in solving problem related to the ability to do mathematical reasoning. The gives an indication that the better the level of intelligence and critical thinking that a person has, the mathematical reasoning ability will follow in the same.

Authors: López Herrera Luis Gabriel 
Published: November 2022

Se midieron seis rasgos funcionales del tallo y hoja de especies que tuvieran diámetros basales mayores o iguales a 5 cm, en ocho parcelas permanentes con coberturas arbustivas sucesionales, en la Cordillera Oriental de Colombia, para describir sus comportamientos funcionales. Para cada rasgo se obtuvieron frecuencias de distribución y correlaciones que permitieron determinar estrategias de tipo adquisitivo y conservativo. La mayoría de las 45 especies registradas tenían hojas pequeñas, área foliar específica baja, asimilación fotosintética máxima baja y altura máxima baja; la densidad de madera más frecuente estaba centrada en la mediana de la distribución. No hubo correlación entre los rasgos foliares y la densidad de madera o la altura máxima. Nueve especies tenían rasgos adquisitivos, con altas tasas de asimilación fotosintética máxima, alta área foliar específica, bajo contenido foliar de materia seca y baja densidad de madera. Por el contrario, 36 especies con rasgos conservativos mostraron bajas tasas de asimilación fotosintética máxima, baja área foliar específica, alto contenido foliar de materia seca y densidad de madera media.

Abstract
Landfills have been identified as one of the main threats to wildlife, such as amphibians, since landfills as they contaminate the aquatic and terrestrial habitat and act as stressors, negatively affecting the development and morphology of amphibians. However, few studies have been realized to know the morphological variation of anurans under environmental disturbances. In this study, we compared the morphological patterns of Rhinella marina in contrasting habitats: a temperate forest and a landfill, in the San Martín de las Cañas dam, Jalisco, Mexico. We analyzed morphology, body traits size and allometric patterns. The Body shape of the landfill toads was more elongated and thinner than that of the forest toads. We found that toads from the forest had greater sizes in most of the morphological traits in comparison to toads from the landfill. Allometric patterns showed that most of the morphological characters had a negative allometric patterns in many traits in toads from both conditions. Rhinella marina has showed affinity for disturbed areas or sites around human settlements, and persists in habitats altered by urbanization. However, our results showed an increase in stress levels in toads that inhabit landfills.

Published: November 2022

Abstract
Culex mosquitoes pose a significant threat to humans and other species due to their ability to carry deadly viruses such as the West Nile and Zika. Washington D.C., in particular, has a humid subtropical climate that makes it ideal as a habitat for mosquito breeding. Thus, tracking mosquitoes’ habitats and breeding patterns in Washington D.C. is crucial for addressing local public health concerns. Although fieldwork techniques have improved over the years, monitoring and analyzing mosquitoes is still difficult, dangerous, and time-consuming. In this work, we propose a solution by creating a Culex mosquito abundance predictor using machine learning techniques to determine under which conditions Culex mosquitoes thrive and reproduce. We used four environmental variables to conduct this experiment: precipitation, specific humidity, enhanced vegetation index (EVI), and surface skin temperature. We obtained sample data of these variables in the Washington D.C. areas from the NASA Giovanni Earth Science Data system, as well as mosquito abundance data collected by the D.C. government. Using these data, we created and compared four machine learning regression models: Random Forest, Decision Tree, Support Vector Machine, and Multi-Layer Perceptron. We searched for the optimal configurations for each model to get the best fitting possible. Random Forest Regressor produced the most accurate prediction of mosquito abundance in an area with the four environment variables, achieving a mean average error of 3.3. EVI was the most significant factor in determining mosquito abundance. Models and findings from this research can be utilized by public health programs for mosquito-related disease observations and predictions.

Abstract
Existing climate change mitigation scenarios for attaining the 1.5°C goal generally phase out hydrocarbon use through decarbonization of the energy system to eliminate fossil fuel usage. However, they require rapid changes in energy-demand technologies and human behaviors or extensive reliance on bioenergy for carbon dioxide removal (CDR). Carbon capture and utilization (CCU) presumably could support to alter such energy systems, considering recent technological advancements in direct air capture (DAC) and renewable-based hydrogen. Here, we developed a CCU-based scenario under the 1.5°C climate goal using a global energy system model. In the scenario where CCU is mainly introduced by limiting demand-side electrification, bioenergy, and CDR, CCU-based synthetic fuel reaches 30% of global energy demand to achieve net-zero emissions by 2050. In contrast to existing 1.5°C scenarios, this CCU scenario is characterized by greater availability of hydrocarbons in energy demand, reaching 280 EJ in 2050, whereas fossil fuel and bioenergy supplies decrease to 60 EJ and 100 EJ, respectively. Despite moderate demand-side electrification, this scenario involves rapid upscaling of renewable energy and DAC, which reach 600 EJ and 10 Gt-CO2 per year by 2050, respectively. While the CCU-based scenario involves multiple challenges on energy supply transformation and associated energy investments, it provides an alternative mitigation option that considers the difficulties in rapid demand-side changes and the risks of bioenergy and CDR.

Abstract
Background: Students' internship year is critical for dental interns to develop the skills and knowledge to perform complete denture rehabilitation (CDR). Online learning is recommended because students can't go to the clinic with the outbreak of COVID-19. This study aims to assess students' intentions toward online learning to improve teaching quality and ensure students master the CDR.
Methods: A questionnaire-based online survey was conducted to evaluate internship students’ background and attitudes to online learning of CDR. The questionnaire consists of three parts and 20 structured questions regarding students’ experience with online learning, students’ knowledge background about CDR, and students’ attitude about online learning CDR. 63 dental interns, including 19 male and 44 female undergraduate dental students, participated in this survey.
Results: 93.65% of the 63 students have participated in online learning, 76.19% believe it is necessary to provide online instruction, and 80.95 % plan to join in the future. 71.42% of the students think they are ready for online learning on CDR. Then, we evaluated students’ knowledge background about CDR. Survey results indicate most students believe they are unprepared to perform CDR in the clinic and only a small percentage of students are familiar with the diagnosis, treatment process, and operation of CDR. Fortunately, interns are incredibly optimistic about the prospect of learning complete dentures online. According to our survey, 60.90% of students enjoy learning online, 71.43% are motivated to continue online learning, and 82.54% believe online learning of CDR is helpful.
Conclusion: According to the survey results, adopting online learning may be a practical solution to guarantee students' quality of oral clinical placements and address the growing shortage of clinical placement opportunities worldwide. Furthermore, the effectiveness and efficiency of online learning need to be further evaluated to ensure they can enhance dental interns’ knowledge level and practical ability of CDR.
Purna River Pirated by a Lineament and Converted its Path into Paleochannel

Published: November 2022

Abstract
A paleochannel of the Purna River basins in the basaltic terrain in the proximity of the village- Daher, and Uga, in Subir Taluka, in the Dang district of Gujarat was discovered by the first author. The discovery of paleochannel is based on a study of satellite imagery, the presence of perennial water springs, and the presence of dense trees with green leaves during summer close to the Purna River. With the help of satellite imagery and ground check, a lineament wasdiscovered near the Purna River paleochannel, which was later renamed as village Girmal- Pipalpada lineament, after the village in which it was found. The total length of this lineament is approximately 22km and the Purna River flows through this lineament for about 1.4km,the Purna River is pirated by this lineament. Due to this piracy of the Purna River, its crescent-shaped old path with the passage of time was converted into a paleochannel. The paleo course of the river is clearly visible in the satellite imagery. This paleo river channel is a good site for sustainable groundwater sources. Presently two open wells are dug in this paleochannel supplying water to four villages. Surprisingly,there is very less depletion of pumping water level (PWL) in the well because of the continuous charging of open wells by this paleochannel.

Published: November 2022

Abstract
Background
Mild hyponatremia is frequently encountered in the pediatric emergency department (PED). Although it is usually of little clinical concern, its prognostic meaning as a possible marker of more severe disease is not well established.
Methods
We retrospectively analyzed data from children and adolescents who performed a blood sample with plasmatic sodium measurement on admission to PED of IRCCS "Burlo Garofolo" Pediatric Hospital in Trieste, Italy, in 2019. We compared the clinical and laboratory characteristics of patients with hyponatremia to those with normal sodium.
Results
Among 807 subjects, hyponatremia (sodium < 135 mEq/L) was present in 17.6%, being mild (134 − 130 mEq/L) in 16.5%. Hyponatremic patients were younger, more frequently males, with an infection diagnosis, mainly of the respiratory tract and of viral aetiology. They presented higher C-reactive protein (CRP) levels and erythrocyte sedimentation rates (ESR). Compared to normonatremic individuals, hyponatremic patients presented a higher risk of an underlying infection (aOR 2.02; 95%CI 1.33–3.08), higher risk of hospital admission (aOR 1.72; 95%CI 1.06–2.48), and a longer hospital stay (aOR 1.99; 95%CI 1.03–3.85). When considering only subjects with mild hyponatremia, we found similar results.
Conclusion
Hyponatremia and mild hyponatremia in the PED are associated with an increased admission rate and longer hospital stay. Mild hyponatremia should be considered a warning sign for a possibly more relevant condition.

Abstract

Background Human immunodeficiency Virus (HIV) and consequently the acquired immune deficiency syndrome (AIDS) remain a significant public health problem, having claimed 36.3 million lives so far. In 2020, approximately 680,000 people died from AIDS-related illnesses worldwide. Despite increased access to antiretroviral treatment (ART), the burden of mortality and morbidity due to advanced HIV disease (AHD) has not significantly changed over the years. AHD individuals are more prone to opportunistic infections– includingMycobacterium tuberculosis(MTB) andCryptococcal meningitis(CM). CM has been reported as a significant cause of mortality among people living with HIV (PLHIV), accounting for 15% of the global AIDS-related deaths in 2019. To keep track of the global commitments made by governments to end the AIDS epidemic as a public health threat by 2030, knowledge of the burden of AHD and its risk factors are essential. Methods A hospital-based cross-sectional study was conducted from February 2020 to February 2021. HIV-infected individuals on ART at the Buea Regional Hospital were screened for AHD using World Health Organization (WHO) consolidated guidelines. A pre-tested semi-structured questionnaire was administered to the consented participants, and blood, sputum, and urine samples were collected. Acid fast bacilli microscopy detection and TB culture were carried out following standard microbiological procedures. Cryptococcus antigen lateral flow tests were performed using sera. Chi-square and regression analysis were carried out on SPSS at a p < 0.05 significance level. Results From a total of 3,229 PLHIV adults on care in the study period, 327 (10.1%) were suspected of having AHD, and were enrolled in the study. Most of the enrolled individuals were women (62.4%) and the mean age of the participants was 40.5 ± 24.7 years. A total of 130 (39.8%, [95% CI, 34.41–45.29]) participants presented with AHD and 41 (35.7%, [95% CI, 26.94–45.12]) and 7 (6.7%, [95% CI, 2.72–13.25) had TB and Cryptococcal infections, respectively. AHD was associated with male gender (aOR; 3.9, 95% CI; 1.40–11.70), and being on ART for more than 12 months was protective (aOR; 0.1, 95% CI; 0.01–0.35). Conclusion Even when ART uptake has dramatically improved in Cameroon, AHD (35.7%) is far beyond the UNAIDS reduction target of 10% by 2020 and thus, improvement in the management of PLHIV is warranted.
