Multivariate statistical analysis to assess the surface water quality of a snow and glacier-fed river: A case from Alaknanda River basin
Authors: Rautela Kuldeep Singh , Kumar Dilip , Khati Bhishm Singh , Rawat Amit , Dubey Amit Kumar
Published: November 2023

The water quality of Himalayan rivers has declined due to human activities, untreated effluent discharge, and poor sewage and drainage systems. The current study aimed to assess the water quality of these rivers using multivariate statistical analysis throughout four seasons. The analyses of 44 surface water samples taken during the monsoon, winter, spring, and summer seasons are well within the ranges acceptable for drinking and domestic use after the sedimentation. The suspended soils and turbidity are highly correlated and affect the water quality index (WQI). The WQI of headwater streams is good during low water flow seasons and poor during high water flow seasons. This is due to the number of melting glaciers and suspended solids/turbidity. Principal component analysis shows that in all the seasons, human activities such as road-cutting projects across the river and natural causes such as intense rainfall and melting of moraine-filled glaciers both impact the WQI. The findings of this study provide important information for future research and policy decisions aimed at improving the water quality of the Himalayan rivers.

Published: November 2023

Introduction:

Enterococcus faecalis (E. faecalis) has been reported as one of the most important causes of failed endodontic treatments. Various antibacterial agents have been suggested to remove E. faecalis from the root canal. We aimed to investigate and compare the antibacterial efficacy of silver diamine fluoride (SDF), Sodium hypochlorite (NaOCl) and ozone gel on E. faecalis in the root canal.

Materials and Methods:

This study involved 60 extracted roots of molar teeth with a single root canal to generate a 6-week-old biofilm for evaluating antibacterial effects. After teeth decorating and removing the smear layer using sodium hypochlorite (2.5%) and EDTA (17%), roots were sterilized by autoclave. Under sterile conditions, 1 ml of the suspension containing E. faecalis bacteria was transferred to each of the microtubes containing teeth. The samples were divided into four groups: exposed to NaOCl (2.5%) as a positive control, exposed to liquid ozone (25 ppm), exposed to SDF (3.8%), and exposed to normal saline as a negative control group. Then, the colony forming unit (CFU) was counted in the studied groups. Kruskal-Wallis test and Dunn-Bonferroni post-hoc analysis were carried out for comparison of CFU in the studied groups.

Results:

The mean of CFU were 17846, 920, 234, and 336 for saline, ozone, NaOCl, and SDF, respectively. There were significant differences in CFU in the comparison of (NaOCl-Ozone), (NaOCl-saline), (SDF-saline), and (ozone-saline) (P< 0.05). However, there was no significant difference for CFU in the comparison of NaOCl-SDF (P= 0.570).

Conclusion:

The study findings showed that NaOCl (2.5%) and SDF (3.8%) were more effective against the 6-week-old E. faecalis biofilms than ozone and saline.

Authors: Sritas Sutisa , Kositamongkol Sudatip , Nukaw Sonthaya , Phetkate Pratya
Published: November 2023

Background:

Less breast milk, breast pain, and engorgement are issues that the majority of postpartum mothers have to confront and overcome.

Objective:

This study examined the efficacy of Manual Lymphatic Drainage (MLD), Thai Traditional Massage (TTM), and standard post-partum nursing care on breast milk volume, breast pain, and engorgement in post-cesarean mothers of preterm infants.

Methods:

Thirty-two participants were randomly divided into 2 groups: an intervention group receiving MLD, TTM, and standard post-partum nursing care (n=16), and a control group receiving standard post-partum nursing care alone (n=16). Outcomes were assessed through breast milk volume, breast pain and engorgement scores, and participant satisfaction.

Results:

The study showed that the group receiving MLD, TTM, and standard post-partum nursing care had a safe and equivalent level of breast milk production compared to the control group. Additionally, there were no significant differences between groups regarding daily milk expression frequency, breast pain, and engorgement over seven days (p>0.05). However, the experimental group expressed a high level of satisfaction with the MLD, TTM, and standard post-partum nursing care interventions.

Conclusion:

The combination of MLD, TTM, and standard post-partum nursing care could be a viable alternative for managing post-cesarean care in mothers with preterm infants.

Immunoinformatics Approach for the Design of Chimeric Vaccine Against Whitmore Disease
Authors: Maurya Shalini , Akhtar Salman , Khan Mohammad Kalim Ahmad
Published: November 2023

Purpose:

Multidrug-resistant Burkholderia pseudomallei is associated with significant morbidity and mortality. Hence, there is a requirement for a vaccine for this pathogen. Using subtractive proteomics and reverse vaccinology approaches, we have designed a chimeric multiepitope vaccine against the pathogen in the present study.

Methods:

Twenty-one non-redundant pathogen proteomes were mined using a subtractive proteomics strategy. Out of these, by various analyses, we found proteins that were non-homologous to humans, essential, and virulent. BLASTp against the PDB database and Pocket druggability analysis yielded nine proteins whose 3D structure is available and are druggable. Four proteins that could be candidates for vaccines were identified by subcellular localization and antigenicity prediction, and they could be used in reverse vaccinology methods to create a chimeric multiepitope vaccine.

Results:

Using online resources and servers, MHC class I, II, and B cell epitopes were identified. The predicted epitopes were selected based on analysis of toxicity, solubility, allergenicity, and hydrophilicity. These predicted epitopes, which were immunogenic, were used for the construction of a multivalent chimeric vaccine. The epitopes, adjuvants, linkers, and PADRE amino acid sequences were employed to create the vaccine. Shortlisted vaccine constructs also interact with the HLA allele and TLR4, as evident from docking and molecular dynamics simulation. Thus, vaccine construct V1 can elicit an immune response against Burkholderia pseudomallei.

Conclusion:

The availability of the proteome of B. pseudomallei has made this study possible through the usage of various in silico approaches. We could shortlist vaccine targets using subtractive proteomics and then construct chimeric vaccines using reverse vaccinology and immunoinformatics approaches.

Authors: Aprilia Dini , Sumiyani Ririn , Tripuspitasari Niniek , Pambudi Ade MWD , Avanti Christina
Published: November 2023

Background:

Lidocaine injection with 2% HCl as an anesthetic drug must guarantee its sterility to avoid microbial contamination. In efforts to maintain the sterile preparation of Lidocaine HCl 2% before use in hospitals, some anesthesiologists opt for re-sterilization.

Objective:

This study aimed to evaluate the impact of plasma sterilization using hydrogen peroxide on Lidocaine HCl levels employing a validated Ultra Performance Liquid Chromatography (UPLC) assay.

Methods:

The 2% Lidocaine HCl samples were separated into two groups, one undergoing re-sterilization with hydrogen peroxide and the other handled only with aseptic techniques. The chromatographic assay was performed using a Waters Corp Acquity UPLC® H-Class system and a Waters Corp Acquity UPLC® BEH C18 column, with a mobile phase of 20% Acetonitrile and 80% Acetate Buffer pH 3.4, flow rate of 0.3 mL/min, and total duration of 4.5 minutes.

Results:

The results showed a decrease in Lidocaine HCl levels to 1.88% after re-sterilization and 2.01% without re-sterilization.

Conclusion:

These findings suggest that re-sterilization with hydrogen peroxide plasma sterilization leads to a significant decrease in Lidocaine HCl levels, causing non-compliance with pharmacopoeia standards.

Published: November 2023

Computer self-efficacy is a pivotal factor in the modern workplace, intertwined with the capacity of the workforce to function effectively and achieve organizational objectives. This study aims to introduce and apply an established computer self-efficacy scale in a novel cultural milieu, seeking to discern the levels of computer self-efficacy among employees while exploring its associations with various control variables, with a specific emphasis on gender. Data collection was accomplished through the distribution of a 12-item scale administered online, which garnered responses from 320 participants. Contrary to prior investigations, the present study revealed no significant disparities in computer self-efficacy between male and female employees. Furthermore, no substantial variations were detected among other control variables, including age, job position, salary, and educational background. This research distinguishes itself through the translation and adaptation of the questionnaire to the Albanian language within a workplace context, setting it apart from previous studies that predominantly focused on student or trainee samples. However, it is worth noting that this research is constrained by its exclusive consideration of computer self-efficacy as a continuous variable, without addressing antecedent and consequent variables.

Authors: Satria Wilia , Riasetiawan Mardhani
Published: November 2023

Automated essay scoring (AES) is used to evaluate and assessment student essays are written based on the questions given. However, there are difficulties in conducting automatic assessments carried out by the system, these difficulties occur due to typing errors (typos), the use of regional languages , or incorrect punctuation. These errors make the assessment less consistent and accurate. Based on the dataset analysis that has been carried out, there is an imbalance between the number of right and wrong answers, so a technique is needed to overcome the data imbalance. Based on the literature, to overcome these problems, the Random Forest and AdaBoost classification algorithms can be used to improve the consistency of classification accuracy and the SMOTE method to overcome data imbalances.The Random Forest method using SMOTE can achieve an F1 measure of 99%, which means that the hybrid method can overcome the problem of imbalanced datasets that are limited to AES. The AdaBoost model with SMOTE produces the highest F1 measure reaching 99% of the entire dataset. The structure of the dataset is something that also affects the performance of the model. So the best model obtained in this study is the Random Forest model with SMOTE.

emplazamiento del antiguo Palacio de Cortés. ¿Una fortaleza medieval en Cuernavaca?
Authors: Cuevas Olascoaga Miguel Ángel
Published: November 2023

A más de 500 años de la conquista de la capital mexica a manos de un reducido grupo de españoles al mando de Hernán Cortés, se ha escrito relativamente poco sobre el papel que jugó la zona geográfica de la antigua Cuauhnáhuac, al sur de la Ciudad de México, a pocas leguas de la capital. A través de una lectura de la cartografía histórica y actual (Cuevas Olascoaga 2022), y una comprensión del asedio que se desarrolló en los pueblos cercanos a Tenochtitlan, podemos entender mejor cómo se concibió la conquista española de este imperio y el papel que jugó dicho lugar de Cuauhnáhuac en la caída de Tenochtitlan.
En aquel entonces, Cortés se encontró con una ciudad situada en un terreno montañoso que él describió como inexpugnable, defendida por el grupo prehispánico de los tlahuicas, quienes ocupaban el territorio de la antigua Cuauhnáhuac. Tras una serie de enfrentamientos y la posterior caída de este pueblo, Cortés aseguró su retaguardia y obtuvo el apoyo de los grupos locales en los últimos días del asedio y la conquista de la gran capital.
 
Después de la conquista, Cortés construyó un edificio en este territorio, hasta cierto punto fortificado gracias a las barreras naturales. En este ensayo, exploraremos criterios importantes que nos permitirán analizar y reflexionar sobre la verdadera naturaleza de este antiguo “Palacio de Cortés”. Nos preguntaremos si dicha edificación tenía un propósito más allá de servir como residencia para la producción de azúcar y otros recursos agrícolas y animales, o si es posible que en todo momento Cortés la consideró como una edificación fortificada para el caso de una probable defensa de sí mismo, de su familia y de su patrimonio. A lo largo de este ensayo, desglosaremos elementos clave que permitirán al lector formar su propia opinión en respuesta a este intrigante cuestionamiento.

The Effects of Industry 4.0 on Indias Economy Industry: A Comprehensive Analysis
Authors: Gaur Dr. Priyanka
Published: November 2023

Abstract: Countries like Germany, Japan, the USA, and Singapore have all embraced Industry 4.0 to increase their economic competitiveness. India has fallen behind its global rivals in its embrace of Industry 4.0. But it has started using these technologies in production, and that's led to a lot of good things happening. Since urbanization began, people have been preoccupied with improving their physical and mental prowess. At first, simple tools were made out of wood or stone, but as time went on, humans experimented with metals, plastics, and even glass for various purposes. Humans have developed a wide range of practical mechanical devices. The advent of new machinery prompted the first industrial revolution. Many people called it a revolution since it also brought about major changes in society and the economy. The new ideas formed during the French Revolution, such as equality, liberty, and fraternity, were infused into the first industrial revolution, which happened a few years after the revolution. This suggests that the global economy and our culture as a whole are profoundly impacted by industrial revolutions. In light of this, the purpose of this research was to demonstrate the potential effects of Industry 4.0 on India's manufacturing industry.

EFL students’ emotional responses to oral feedback: The case of Indonesia
Authors: Purwandari Junita Duwi
Published: November 2023

Feedback, a crucial component in supporting student learning, has been subject to extensive research in the field of English as a Foreign Language (EFL). Although some studies have explored students' emotional reactions to written feedback provided by teachers, there is a scarcity of research on emotional responses to oral feedback. Thus, this case study seeks to enhance the existing literature by investigating how students emotionally react to oral feedback. The study argues that the manner in which oral feedback is delivered can elicit unexpected emotional responses from students. This study was conducted in three senior high schools in Jakarta, Indonesia, with six participants from each school. Each student participated in a semi-structured interview, resulting in a total of 18 interview data. Thematic analysis was employed to analyze the data. The findings revealed that students expressed both positive and negative emotions in response to teacher oral feedback, with a tendency towards the latter outweighing the former, resembling an imbalanced scale. This study contributes to a deeper understanding of students' reactions to oral feedback and encourages teachers to reflect on their feedback practices.

Timely positive feedback to students pursuing a Ph.D. program motivates completion.  Drawing upon Skinner's Reinforcement theory and Lakoff and Johnson's Conceptual Metaphor Theory (CMT), this study aimed at uncovering metaphors employed in feedback practices by exploring the linguistic expressions of supervisors and peers, which encouraged students to complete their Ph.D. studies in Australia. The methodology employed the use of a semi-structured interview to delve into the lived experiences of two Indonesian Ph.D. students (currently EFL lecturers) during their studies in Australia. The results that the use of positive expressions from supervisors and peers strongly motivated the students to complete their Ph.D. programs. The four types of expressions used served to praise, give hope, give direction as feedback to support completion, and reminders to keep the student on track. The following expressions were commonly used to motivate completion: "Do not worry, mate, you will get there," and "Wow, it's great work! I understand it is not easy to write academically in such good English, but you did." These expressions metaphorically imply that:  "PhD study is a journey," and "Work speaks louder than words." These findings suggest that positive verbal feedback from supervisors' and peers' can motivate PhD students' completion.

Published: November 2023

Esta obra está centrada principalmente en el análisis de los sistemas eléctricos de potencia (SEP) a partir de la solución del problema de Flujo de Carga (FC) considerando una amplia variedad de modelos y representaciones de los diferentes componentes eléctricos de la red. La representación matricial de la red es un aspecto esencial en este texto, de forma que facilite la implementación computacional de métodos de solución de sistemas de gran tamaño. También este aspecto es fundamental para el análisis de sistemas con estructuras matemáticas de gran complejidad. Generalmente, una obra con el alcance que aquí se expone es presentada en único tomo. Sin embargo, por restricciones editoriales referentes al número máximo de páginas por publicación, se ha optado por presentar el contenido completo de la obra en dos tomos. El primero aborda aspectos sobre el modelamiento del problema de FC tradicional. El segundo tomo aborda el problema de FC óptimo, el cual proporciona al estudiante algunas herramientas básicas de optimización matemática aplicables al planeamiento y operación del SEP.
Suppression and facilitation of motion perception in humans with single motion stimulus
Authors: Tzvetanov Tzvetomir
Published: November 2023

Research groups use the single motion stimulus design of Dr. D.Tadin
​(Tadin, Lappin, Gilroy & Blake, 2003) that allows to putatively assess
spatio-contrast excitatory and inhibitory effects from duration
threshold data of motion perception. The present work presents the
correct neurocomputational model for this experimental design and
analyses issues related to data and model comparisons, among which: (1)
once the full computational model that predicts the psychophysical
results is properly defined, it is shown that two low-level models of
how inhibition acts on neuronal activity, i.e. “divisive inhibition”
and “subtractive inhibition”, predict exactly the same thresholds and
cannot arguably be claimed that one is better than another one, (2) it
is excitatory and inhibitory processes that are the mechanisms shaping
threshold changes, i.e. perceptual “facilitation” and “suppression”
in the behavioural domain, (3) that this experimental design allows a
quantitative comparison and usage of such “contrast–size tuning”
data, (4) that such studies must be carefully designed once the model is
correctly understood and applied, because of the rather large parameter
space (~10-12 variables) necessary to explain the
behavioural measures even in such simple experiments.
Using acoustic survey data to improve eBird-based species distribution models for tropical rainforest birds
Authors: Rumelt Reid , Searcy Christopher
Published: November 2023

A key goal in ecology is to develop more effective ways to understand
species’ distributions in order to facilitate both their study and
conservation. Many species distribution modeling analyses have been
performed to date, using either structured survey data or unstructured
citizen science data; these two pools of data have tradeoffs in terms of
data density, spatiotemporal coverage, and accuracy. Recent studies have
shown that combining structured and unstructured survey data can greatly
improve the accuracy of species distribution models for birds, but most
of this work has focused on north temperate bird species and uses bird
atlas data that is much more common in the temperate zone than
elsewhere. We sought to adapt a data pooling approach from the
literature on north temperate bird biology to create distribution models
for a selection of secretive suboscine bird species that occur in a
highly diverse region of the southwestern Amazon.
Echolocation source levels and detection distances of bat assemblages in biomes of South Africa: A test of the Acoustic Adaptation Hypothesis
Authors: Wechuli David , Holderied Marc , Jacobs David
Published: November 2023

Echolocating bats use and adapt ultrasound pulses that vary in several
parameters, one of them being the pulse’s source level, which is a
measure of the emitted sound amplitude. This is a vital ecological
parameter as it directly impacts the maximum distance over which bats
can perceive targets in their environment, most importantly their prey.
Different habitats present different sensing challenges for echolocation
systems, and the quality and content of information derived from
echolocation pulses reflect these environmental challenges. As such,
echolocation pulses within or between species may vary from one habitat
to the next due to variable selection pressure, resulting in local
adaptation. Habitat is, therefore, a key component in shaping the
evolution of echolocation. The Acoustic Adaptation Hypothesis (AAH)
proposes that acoustic properties of the environment influence sound
propagation and therefore the evolution of echolocation pulses. Here, we
tested the AAH using multiple microphone arrays to measure the source
levels of echolocation pulses of 14 bat species in bat assemblages
across sites in six biomes in South Africa. Contrary to the AAH, our
results revealed that bats in the same assemblage used different
echolocation pulse source levels, frequencies, and duration resulting in
different detection distances, which differ among bat assemblages
occupying different sites. Furthermore, detection distance was
species-specific and remained similar within species between
assemblages; suggesting that species is a better predictor of detection
distances compared to habitat as indicated by Miniopterus natalensis
across all seven sites. KEYWORDS: adaptation, bat assemblages, detection
distances, microphone arrays, selection pressure, source levels

This paper presents an empirical analysis of using deep learning
features with an Extreme Learning Machine (ELM) for automatic modulation
classification in wireless communication. The study utilizes advanced
pre-deep learning models like VGG 16, Resnet 50, and Inception V3 to
extract features, which are then fed to an ELM for classification. The
ELM’s performance is enhanced by the moth flame optimization method
(MFOP-ELM). To measure the efficacy of the proposed model, it is tested
on two standard datasets - RADIOML2016.10A and RADIOML 2018.01A. The
paper also compares the proposed model with other classifiers such as
SVM, K-NN, and BPNN. Results show that the proposed model using
Inception V3 features with the MFOP-ELM classifier outperforms other
state-of-the-art models.
