Adsorption of iron and manganese from acid mine drainage by zalacca (Salacca zalacca) peel- activated carbon
Authors: Anifah Eka , Ariani Ismi Khairunnissa , Tindaon Janet Tio Panny , Basransyah
Published: May 2024

The low pH and high metal concentration in acid mine drainage cause environmental problems and affect human health. Adsorption not only removes the pollutants but also increases pH levels. Natural adsorbents have gained attention because of their widespread availability, low cost, and effectiveness. Zalacca peel waste is among the biomass materials showing promise as activated carbon for removing contaminants from acid mine drainage. This study aims to investigate the adsorption capacity of activated carbon from zalacca peel for removing iron and manganese from acid mine drainage. Adsorption studies were conducted in batch experiments using various dosages and contact times. Optimal results were achieved with a dosage of 0.8 grams per 100 mL and contact time of 60 minutes, resulting in 80% removal efficiency for iron and 24% for manganese. The neutralization process occurred post-adsorption, bringing the final pH close to neutral levels, suitable for environmentally safe discharge. Experiment data were fitted to the Freundlich isotherm and pseudo-second order kinetics. FTIR analysis revealed functional groups including C-H, C-O, and C=C was found in the adsorbent. Furthermore, surface area and pore volume experienced slight increases following activation with KOH.
A semi-automated workflow for DIA-based global discovery to pathway-driven PRM analysis
Authors: Guergues Jennifer , Wohlfahrt Jessica , Koomen John , Krieger Jonathan , Varma Sameer , Jr. Stanley Stevens,
Published: May 2024

Targeted proteomics, which includes parallel reaction monitoring (PRM),
is typically utilized for more precise detection and quantitation of key
proteins and/or pathways derived from complex discovery proteomics
datasets. Initial discovery-based analysis using data independent
acquisition (DIA) can obtain deep proteome coverage with low data
missingness while targeted PRM assays can provide additional benefits in
further eliminating missing data and optimizing measurement precision.
However, PRM method development from bioinformatic predictions can be
tedious and time-consuming because of the DIA output complexity. We
address this limitation with a Python script that rapidly generates a
PRM method for the TIMS-TOF platform using DIA data and a user-defined
target list. To evaluate the script, DIA data generated from HeLa cell
lysate (200 ng, 45-minute gradient method) as well as canonical pathway
information from Ingenuity Pathway Analysis was utilized to generated a
pathway-driven PRM method. Subsequent PRM analysis of targets within the
example pathway, regulation of apoptosis, resulted in improved
chromatographic data and enhanced quantitation precision (100% peptides
below 10% CV with a median CV of 2.9%, n=3 technical replicates). The
script is freely available at
https://github.com/StevensOmicsLab/PRM-script and provides a framework
that can be adapted to multiple DDA/DIA data outputs and
instrument-specific PRM method types.
Potential of Raman-reflectance combination to quantify liver steatosis and fat droplet size: evidence from Monte Carlo simulations and phantom studies
Authors: Guo Hao , Zions Vanessa S. , Law Brent A. , Hewitt Kevin
Published: May 2024

This study explores a combined strategy of Raman and reflectance
spectroscopy for quantifying liver fat content and fat droplet size,
crucial in assessing donor livers. By using Monte Carlo simulations and
experimental setups with oil-in-water phantoms, our findings indicate
that Raman scattering can solely differentiate between varying fat
contents, while reflectance intensity is influenced by both fat content
and oil droplet size, with a more pronounced sensitivity to fat droplet
size. This study demonstrates the efficacy of combined Raman and
reflectance spectroscopy in assessing liver steatosis and fat droplet
size, potentially aiding in assessing donor livers for transplantation.
On some topological aspects in neutrosophic-2- normed spaces
Authors: Kumar Vijay , Murtaza Sajid , Sharma Archana
Published: May 2024

In present paper, we introduce the concepts of neutrosophic boundedness,
neutrosophic compactness in neutrosophic 2-normed spaces and analyze some of
their topological properties. We show that if the space is finite
dimensional then any two neutrosophic 2-norms are equivalent. Finally, we
defined neutrosophic boundedness and neutrosophic continuity of linear
operators and study some of their properties.

Published: May 2024

Background and purpose: Few studies report on long-term levels of physical activity after THA compared with a control population. This case-control study aimed to find the long-term habitual level of leisure-time physical activity after THA and compare it with a large control group.Patients and methods: A randomized sample of 856 patients, treated with primary THA, were identified from the Norwegian Arthroplasty Register. 429 (50%) responded to a questionnaire with a mean follow-up time of 9.6 years. We compared them with a control group of 29,272 (64%) from a population-based health study. Physical activity was measured with a questionnaire and categorized into groups according to the general recommendations for physical activity.Results: 245 (63%) of the THA cases reported a level of leisure-time physical activity meeting the general recommendations, compared with 10,803 (39%) in the control group. The difference persisted at all ages (50–90 years). In sex, age, and BMI-adjusted regression models the chance of meeting the physical activity recommendations was higher in the THA group than in the control group (OR 2.9, 95% confidence interval 2.4–3.6).Conclusion: The majority of the patients with THA reported a level of leisure-time physical activity meeting the general recommendations for physical activity. THA patients were more physically active in their leisure time than a control group representing a normal population.

Authors: Biebricher Christine , Feick Diana , Knorr Petra
Published: May 2024

In the discussion of international student mobility, virtual exchange(s) (VE) become increasingly important. Similar to on-site exchanges, VEs aim to provide students with an international experience and transcend geographical, social, and cultural boundaries. While students’ experiences with VEs have been presented repeatedly, this paper focuses on an aspect that features less prominently in the literature: the perceptions of a VE from the perspective of the facilitating team. We report on our experiences, interactions and reflections as supporting teacher educators in a VE project between German and New Zealand pre-service English teachers and New Zealand students of German. We employ the collaborative research approach of duoethnography to critically reflect on our experiences and practices with the VE as well as to portray our reflections on duoethnography as our chosen research approach. Our findings are based on continuous individual and collaborative written reflections throughout the project.

Le Castia-gilos, entre sérieux et comique (et pour un possible intertexte ovidien de Ramon Vidal)
Authors: Menichetti Caterina
Published: May 2024

L’articolo propone una nuova lettura della breve narrazione occitana in distici di ottosillabi nota come Castia-gilos, composta dal trovatore Ramon Vidal verosimilmente tra la fine del XII secolo e l'inizio del XIII sec. L'analisi presta particolare attenzione alle situazioni e agli sviluppi narrativi del triangolo amoroso tra Amfos de Barbastre, sua moglie Alvira e il cavaliere Bascol de Cotanda, e mostra come questi elementi trovino significative corrispondenze nelle narrazioni tragiche di età medievale. L'antecedente diretto della scena chiave dei Castia-gilos, la trappola di Amfos per Alvira e la caccia al marito, è riconosciuto d’altra parte nell'episodio tragico di Procri e Cefalo delle Metamorfosi di Ovidio (VII, v. 685-862). L'articolo ha come obiettivo ultimo quello di spiegare il significato di queste risonanze tragiche – provenienti tanto dalla narrativa volgare del Medioevo quanto dalla letteratura classica – in una storia dal tono fortemente comico.

Published: May 2024

La utilización de los recursos TIC tiene el potencial de mejorar la enseñanza y el aprendizaje, según la literatura. Para determinar la posible influencia de los libros electrónicos en el rendimiento de los estudiantes en física, no se ha realizado ninguna investigación empírica en Nigeria. De ahí la necesidad de este estudio. Utilizando un diseño de investigación simple de medidas repetidas, este estudio fue impulsado por una metodología de investigación cuantitativa. El estudio incluyó a 58 estudiantes de física de secundaria superior dos (2) que fueron seleccionados al azar de escuelas secundarias en la zona educativa de Nsukka. Para recopilar los datos se utilizó el Physics Achievement Test (PAT), que ha sido probado y validado de cara y contenido. La confiabilidad de consistencia interna para los componentes PAT fue .76. Se utilizó el análisis de varianza de medidas repetidas para analizar los datos recopilados. Se descubrió que el acceso de los alumnos a los libros electrónicos tuvo un impacto significativo (p < .05) en su desempeño en Física. Este hallazgo de investigación tiene implicaciones para el asesoramiento en el sentido de que los maestros y sus escuelas deben recibir orientación educativa y asesoramiento por parte del bibliotecario-consejero sobre las implicaciones legales y éticas del uso de recursos de TIC como libros electrónicos para impartir instrucciones de física en las escuelas.
The radiographic appearance of the canine femoral nutrient foramen for dogs undergoing total hip replacement is consistent, with some variations
Authors: Scott Peter , Paran Emilie , Bradley Kate
Published: May 2024

OBJECTIVE

This study aimed to document the radiographic appearance of the femoral nutrient foramina and the variation of this in dogs undergoing total hip replacement (THR). Our hypothesis was that the radiographic appearance of the foramen would be consistent with the previously described anatomy, with some variations.

ANIMALS

89 client-owned dogs.

METHODS

Preoperative radiographs were retrospectively analyzed for dogs undergoing THR at a single referral center. The signalment of all dogs was recorded. Radiographs were retrospectively examined to describe the number, direction, appearance, and foraminal index of the femoral nutrient foramen.

RESULTS

Radiographs of 89 dogs and 102 femurs were examined. In 73 cases, a single foramen was seen; in 19 cases, no foramen was visible; and in 10 cases, 2 foramina were visible. The median foraminal index was 33.1% (range, 26% to 55.3%). On the mediolateral view, 72 were of proximocaudal-to-distocranial orientation, 19 were proximocranial to distocaudal, and 1 was atypical. On the craniocaudal or ventrodorsal views, the foramen was seen as a focal round radiolucency in 65 cases, was curved or atypical in 13 cases, and was not visible in 14.

CLINICAL RELEVANCE

Radiolucent lines across the cortices that do not fit these criteria should raise suspicion of a femoral fissure, particularly within the context of THR.
Exploring Asymmetric GARCH Models for Predicting Indian Base Metal Price Volatility
Authors: Kumar Arya , Sahoo Jyotirmayee , Sahoo Jyotsnarani , Nanda Subhashree , Debyani Devi
Published: May 2024

Research background

Many studies have been done in the field of predicting the Volatility of Commodities; however, very little or no analysis has been conducted on any sector, industry, or indices to identify which model is best to understand the asset’s characteristics, as there is a hypothesis that all financial time series can be interpreted by implementing the same model.

Purpose

The primary objective is to identify different tools developed by the researchers in estimating impulsive clustering and leverage effects. A comparison will be made among the available tools of the GARCH family models to suggest the best tool to forecast and calculate volatility with the least error.

Research methodology

The data used are historical time series data of Indian base metal indices, i.e., Aluminum (AL), Copper (CO), Lead (LE), Nickel (NI), and Zinc (ZI) from NSE for a period from 1st June 2012 to 31st August 2022 from the official website of NSE of India. The study compared and attempted to identify which GARCH family model is suitable to measure the volatility clustering and leverage effect in Indian base metal indices by reducing the chances of error.

Results

The study has revealed that the GRACH asymmetric models, while approximating and predicting the financial time series, can enhance the model’s output when it has a high frequency. Here, the asymmetric GARCH models (TARCH, CGARCH, EGARCH, and PARCH) better predict volatility than classic models.

Novelty

This study is original in its approach, as a previous study stated the presence of volatility or leverage effect by implementing any one tool. However, this study will compare available tools to suggest which is appropriate for which sector. This analysis will support future researchers and practitioners in evaluating volatility clustering and the effect of leverage by implementing the appropriate GARCH family model without believing in a hypothesis that a single model is good enough to predict volatility.
Impact of Trade Openness on Government Expenditure in South Africa: an ARDL Approach
Authors: Maluleke Glenda
Published: May 2024

Research background

Numerous studies have been conducted on the relationship between trade openness and government expenditure in several developing countries including African countries, however, the studies are limited in South Africa. Therefore, South Africa does not have adequate empirical studies regarding the impact of trade openness on government expenditure, which could assist in developing their trade policies.

Purpose

The study examines the relationship between trade openness and government expenditure in South Africa for the period 1980 to 2021.

Research methodology

The study uses the autoregressive distributed lag (ARDL) bounds testing approach to cointegration for estimation of the three Models in the study.

Results

The estimation results of all of the three models found that in the short run trade openness has a positive and significant impact on government expenditure in South Africa. The results also suggest that the increase in government expenditure seems to be as a result of trade openness, urbanisation and dependency ratio in the short run while inflation also leads to an increase but only in the long run.

Novelty

The study uses three proxies of trade openness which are total trade, ratio of exports, and ratio of imports as a percentage of GDP. To the best of our knowledge, the study may be the first of its kind to empirically examine the impact of trade openness on government expenditure in South Africa using three proxies in a single study.

Authors: Maddi Abdelghani , Silva Jaime A. Teixeira da
Published: May 2024

Purpose

This study aims to evaluate the accuracy of authorship attributions in scientific publications, focusing on the fairness and precision of individual contributions within academic works.

Design/methodology/approach

The study analyzes 81,823 publications from the journal PLOS ONE, covering the period from January 2018 to June 2023. It examines the authorship attributions within these publications to try and determine the prevalence of inappropriate authorship. It also investigates the demographic and professional profiles of affected authors, exploring trends and potential factors contributing to inaccuracies in authorship.

Findings

Surprisingly, 9.14% of articles feature at least one author with inappropriate authorship, affecting over 14,000 individuals (2.56% of the sample). Inappropriate authorship is more concentrated in Asia, Africa, and specific European countries like Italy. Established researchers with significant publication records and those affiliated with companies or nonprofits show higher instances of potential monetary authorship.

Research limitations

Our findings are based on contributions as declared by the authors, which implies a degree of trust in their transparency. However, this reliance on self-reporting may introduce biases or inaccuracies into the dataset. Further research could employ additional verification methods to enhance the reliability of the findings.

Practical implications

These findings have significant implications for journal publishers, highlighting the necessity for robust control mechanisms to ensure the integrity of authorship attributions. Moreover, researchers must exercise discernment in determining when to acknowledge a contributor and when to include them in the author list. Addressing these issues is crucial for maintaining the credibility and fairness of academic publications.

Originality/value

This study contributes to an understanding of critical issues within academic authorship, shedding light on the prevalence and impact of inappropriate authorship attributions. By calling for a nuanced approach to ensure accurate credit is given where it is due, the study underscores the importance of upholding ethical standards in scholarly publishing.

Authors: LETYAGINA Elena N. , PEROVA Valentina I.
Published: May 2024

Subject. The article examines the condition of regional innovation ecosystems of the Russian Federation for sustainable development and technological sovereignty of the country under import substitution due to high external challenges.
Objectives. The aim is to solve the multifactorial task of analyzing the development of innovative ecosystems in Russia’s regions. The task is characterized by complex formalization, and it is in line with modern concepts of competitive potential, through the proposed productive method, i.e. neural network cluster data analysis.
Methods. We employ the cluster analysis based on neural networks that formed an essential component of artificial intelligence. The functionality of artificial neural networks – Kohonen self-organizing maps, involved in this work, has no model prohibitions. The method of neural network cluster analysis enables to visualize clustering results of the multidimensional source data space.
Results. The neural network cluster analysis of a set of heterogeneous data helped get the integration of Russian regions across seven clusters. We obtained a significant variety of placement of Russian regions by cluster: the number of regions in clusters varies from one to thirty-one.

Severe Hydrocarbon Pneumonitis, A Fatal Complication of Petroleum Aspiration: A Case Report
Authors: Francis Neema , Asapu Phalguni , Husain Mansoor , Jaiganesh Thiagarajan
Published: May 2024

This case report outlines a patient who ingested and aspirated petroleum, leading to acute respiratory distress syndrome (ARDS), chemical pneumonitis, and subsequent complications. Despite rigorous interventions, the patient's condition worsened, resulting in his death. This report highlights the challenges in managing such cases and underscores the importance of early recognition, aggressive treatment, and multidisciplinary care.
Introduction:
Severe hydrocarbon pneumonitis from petroleum ingestion is rare, with an incidence of less than 2%. Children are particularly vulnerable due to accidental ingestion of household items containing hydrocarbons. Occupational exposure and fuel siphoning, especially in developing countries, are other common risk factors. Hydrocarbon pneumonitis occurs when hydrocarbons are inhaled or ingested, disrupting lung surfactant function, leading to decreased pulmonary compliance, bronchial edema, and lung tissue damage.
Case Presentation:
This report presents a 28-year-old male who developed hydrocarbon pneumonitis after accidentally ingesting and aspirating petroleum while siphoning fuel. The patient experienced violent coughing and a significant drop in oxygen saturation. Upon arrival at the hospital, he was in severe respiratory distress and required urgent intubation and intensive care. Imaging revealed extensive lung damage, confirming severe hydrocarbon pneumonitis. Transfer to a facility with extracorporeal membrane oxygenation (ECMO) capabilities was hindered by his critical condition. The patient was managed symptomatically, with continuous monitoring and interventions such as chest tube insertions. Despite these efforts, his condition deteriorated further, leading to bilateral lung injury, multi-organ failure, and death.
Conclusion:
Supportive care is essential in managing hydrocarbon pneumonitis, with about 80% of cases resolving with symptomatic treatment. Early recognition and intervention are crucial to prevent severe complications like pneumothorax and ARDS, which occur in 10-15% of cases. Advanced therapies such as ECMO are considered for severe cases, required by 5-10% of patients with unresponsive respiratory distress. Generally, the prognosis is favorable, though severe complications can lead to a 10-30% mortality rate. Further research is needed to refine treatment strategies and preventive measures.
Enhancing Customer Retention through Deep Learning and Imbalanced Data Techniques

Published: May 2024

Accurately predicting customer churn is considered crucial by businesses in order to take proactive measures to retain their customers and avoid financial losses. In this paper, a customer churn prediction model is proposed that incorporates deep neural networks and imbalanced data techniques. The approach involves applying oversampling and undersampling methods to address class imbalances in the dataset. The model's performance is evaluated using various evaluation metrics and compared to other methods. The results demonstrate that superior performance in predicting customer churn is achieved by the proposed model compared to traditional statistical methods and deep neural networks without imbalanced data techniques. Important implications for businesses seeking to reduce customer churn and improve customer retention are provided by our findings. By using the suggested model, customers can be retained, and financial losses can be avoided proactively.
They Broke Bread with Sincere Hearts
Authors: Ellerbe Briana
Published: May 2024

This article discusses everyday acts of resistance through two stories of bread in competitive gymnastics through the lens of infrapolitics and hidden transcripts. The author discusses how the culture of elite competitive gymnastics sometimes makes it difficult to distinguish between appropriate and inappropriate methods of coaching and care—often giving rise to infrapolitical acts. Furthermore, the article centers Larry Nassar’s cooptation of gymnasts’ hidden transcripts—particularly around food—as a strategy to further his abuse of hundreds of athletes. Finally, through the concept of the civic imagination, the author encourages the gymnastics community to begin to engage in open discussions over meals toward change in gymnastics cultures.
The Role of the Royal Family in Transforming the Institution of Traditional Leadership in South Africa
Authors: Ntlama-Makhanya Nomthandazo
Published: May 2024

This article focuses on the institutional role of the royal family in the promotion of the transformative aspirations of the new dawn of democracy, particularly the right to gender equality within the institution of traditional leadership. The article argues that the royal family is foundational to the regulation of traditional authority regarding the pursuit of the principles of non-discrimination to ensure the preservation of the identity of the institution of traditional leadership. The argument is limited to the institution that follows the patriarchal system of governance with ascension to the throne that is restricted to males only and not on matrilineal systems, regency, or any other leadership position that is available within the institution. The focus is triggered by the constitutionalised status of customary law that has subjected the institution of traditional leadership under intense constitutional scrutiny for its compliance with the transformative ideals of the constitutional dispensation. Such scrutiny is grounded by the Constitution, 1996 which is contextualised by the adoption of the Traditional Leadership and Khoisan Act 3 of 2019 (National Act), which gave the institution affirmative responsibilities to promote principles of equality and non-discrimination. This role is of keen interest, particularly with the judicial developments that have opened opportunities for women within royal households to ascend to the throne. These opportunities then raise a question regarding the preservation of the institutional identity of the traditional community.
Successful endonasal transsphenoidal surgery to treat acute internal carotid artery occlusion caused by pituitary apoplexy: Usefulness of arterial spin labeling imaging for emergency decision
Authors: Aoki Takuma , Furuno Yuichi , Fuji Keisuke , Kuwayama Kazuyuki , Matsumoto Keigo
Published: May 2024

Background:

Pituitary apoplexy (PA) is a rare clinical condition presenting with acute headache, visual disturbance, and disorientation. PA can cause strokes due to acute internal cervical artery occlusion (ICO), which is an extremely rare condition. Arterial spin labeling (ASL) on magnetic resonance imaging (MRI) is a popular technique, which is a quantitative perfusion imaging useful for the diagnosis of ischemia. We report a treatment with acute pseudo-ICO in which ASL on MRI was useful for the decision of surgery timing.

Case Description:

A 50-year-old male presented with a sudden headache and nausea. MRI and magnetic resonance angiography revealed a large pituitary tumor and left ICO. However, the left middle cerebral and anterior cerebral arteries were depicted due to a cross-flow through the anterior communicating artery. ASL on MRI showed decreased perfusion of the left hemisphere, suggesting acute ICO. As he had no neurological deficit, we treated him conservatively, following the guidelines. Two days after admission, he presented with sensory aphasia and incomplete right paralysis. Emergency head computed tomography revealed a low-density area in his left temporal lobe. We decided on emergency tumor decompression surgery to prevent ischemic progression. We performed endonasal transsphenoidal surgery. Postoperative MRI showed recanalization of the left internal carotid artery (ICA). His incomplete right paralysis improved immediately after surgery but remains mild sensory aphasia.

Conclusion:

ICO-related PA is a very rare occasion but there are few similar reports. Some cases of successful ICO treatment due to PA have been reported, but the question of whether emergency or elective surgery is better remains unanswered. Our case may have been no neurological deficit if we had decided to have surgery on admission. Hypoperfusion of the ICA area due to PA may be an adaptation of emergency surgery. Perfusion images like ASL could be a useful technique to decide on surgery or conservative treatment.
