A case study on the recovery of unevenly embedded particle size in high-carbon chalcopyrite using an alkyne-based thioester collector: Flotation processing and adsorption mechanism
Authors: Qi Yuechao , Luo Yunbo , Qiu Xianyang , Wei Dezhou , Zhang Faming , Wang Chenghang
Published: April 2024

The difference in chalcopyrite's primary ore-hosting rocks (dolomite and carbonaceous slate) in the Democratic Republic of the Congo results in an extremely uneven grain size distribution. Additionally, the presence of 2.21% organic carbon in the gangue impacts flotation efficiency. To address these challenges, ore properties were analyzed using the Mineral Liberation Analyzer (MLA), X-Ray Diffractometer (XRD), and microscopy. Flotation process was modified to incorporate a "middlings regrinding" processing, utilizing PDEC (an alkyne-based thioester collector, prop-2-yn-1-yl diethylcarbamodithioate) as the collector for experimental studies. Density Functional Theory (DFT) calculations elucidated the interaction mechanism of PDEC on chalcopyrite's surface. The MLA analysis indicates that chalcopyrite is mainly found in medium to fine grains, with the presence of fine-grained copper minerals smaller than 0.04mm accounting for 16.29% of the sample. This implies that these minerals require fine grinding for effective separation. Despite interference from organic carbon, PDEC demonstrates remarkable selectivity and efficiency in chalcopyrite flotation. By employing the "middlings regrinding" flotation method, a concentrate with a Cu content of 26.79% and a recovery of 87.88% was achieved, representing an increase of 0.17% in Cu grade and 4.09% in recovery rate compared to the conventional flotation process. DFT analysis demonstrates that the S 3p orbitals in carbon-sulfur double bond of PDEC and the C 2p orbitals in its acetylene group significantly affect its collection efficiency, engaging in hybridization with the Fe 3d orbitals on the surface of chalcopyrite, thereby facilitating a robust bonding interaction.

Vector Fixed Point Approach to Control of Kolmogorov Differential Systems
Authors: Hofman Alexandru , Precup Radu
Published: April 2024

The paper presents a vector approach to control problems for systems of equations. The method is described in the case of Kolmogorov systems which arise frequently in the dynamics of populations. Three types of problems are discussed: problems with control of both per capita growth rates, problems with control parameters acting on the growth rates, and problems which combine the first two types. The controllability is obtained via a vector approach based on the Perov fixed point theorem and matrices which are convergent to zero. Four concrete illustrative examples are added.

As part of the newly designed operational R&D budget build methodology in 2022, this research develops a process to fill this void. This research presents a novel design for a decision support tool, that’s results will aid in the decision maker’s analysis of project prioritization and increase the overall value of R&D initiatives in context of MSC portfolios. The Scalable Weighted Operational R&D Decision (SWORD) Tool will build upon the current objectives outlined by ERDC in their Operational Research & Development Playbook v1.0 to ensure alignment to the new ERDC operational R&D process. Moreover, the ERDC validated SWORD Tool supports commensurate adjustments, ensuring future project portfolios continue to reflect command priorities.
Feeding the Needy through Feedback – A Systems Dynamics Analysis of New Jersey’s Supplemental Nutrition Assistance Program
Authors: Milian Natalya , Dabkowski Matthew , Mellon Jonathan
Published: April 2024

Social welfare initiatives in the United States strive to help as many people as possible with limited resources and within budgetary constraints. One such program is the Supplemental Nutrition Assistance Program (SNAP), colloquially known as food stamps, which provides income to people in need so they can purchase groceries. Although well-intended, critics of SNAP question not only its efficiency but also its efficacy due to its lack of access and inability to provide adequate benefits to its participants (Oliveira et al., 2018). This study models SNAP using systems dynamics, allowing us to examine these concerns and, when warranted, develop potential solutions. Specifically, we leverage the software Vensim to simulate New Jersey’s SNAP. Our findings suggest SNAP should focus its efforts on reaching the eligible population versus the program. These results are not merely academic; they are potentially actionable, as they can be used to reallocate existing funding.
Towards Digital Forensic Readiness: A Framework for Financial Service Providers
Authors: Odhiambo Georgina , Omollo Richard , Abuonji Paul
Published: April 2024

Digital Forensic Readiness has widely been referred to as an organization’s ability to proactively capture digital evidence and as a result, incur minimum costs of investigation in the event of incidents.  However, several organizations still underestimate the usefulness of setting up their environments to be forensically ready until an incident occurs, and this often results in huge losses and costly investigations. Global trends show that financial institutions are amongst the worst-hit companies by cybercriminals, and this is attributed to one of the key motivations for cybercrime, which is financial gain. Kenya’s cybercrime statistics over the past five years also show that financial services remain amongst the top hit sectors by cybercriminals. The aim of this study was to develop a Digital Forensic Readiness framework for Financial Services Providers. To achieve this, the study assessed the relevant existing frameworks to explore their strengths and gaps. Additionally, the study explored the current state of forensic readiness in Kenyan financial institutions by reviewing secondary data and analysing primary data collected from respondents in the financial services sector. The study adopted a descriptive research design with the main data collection tool being questionnaires, which were administered to respondents through an online survey. The collected data was analysed using the SPSS software 28.0.1 and a multiple regression analysis was performed to determine the influence of organizational factors, legal factors, technology, and policies on Digital Forensic Readiness. The outcome of the analysis indicated that these factors indeed had a significant effect on forensic readiness, with organizational factors and policies having more impact on the framework. The study recommended that organizations not only focus on complying with laws and implementing technological controls, but also prioritize improving forensic readiness awareness and culture, supporting forensic readiness activities, setting up training, and enforcing policies to ensure personnel compliance
Lipopeptide adjuvants for antibiotics and vaccines: the future step in the fight against multidrug-resistant and extensively drug-resistant pathogens
Authors: Sebilleau Chloé O. , Sucheck Steven J.
Published: April 2024

With the surge of antibiotic resistance in bacteria, the need for a larger arsenal of effective antibiotics and vaccines has drastically increased in the past decades. Antibiotics like vaccines can benefit from significant potentiation when used in combination with adjuvants. Antibiotic adjuvants can allow for gram-positive bacteria (GPB) specific treatments to be used against gram-negative bacteria (GNB) infections, with minimal antimicrobial resistance (AMR). In the case of vaccines, they allow for modulation and increase of the immune response. Lipopeptides are molecules of choice because of their ability to activate specific cell surface receptors, penetrate the outer membrane of GNB, safety and ease of synthesis. This review explores the recent developments in lipopeptide adjuvants for antibiotics and vaccines, providing a roadmap on how to develop adjuvants to efficiently combat AMR. After a brief overview of bacterial resistance, lipopeptide adjuvants for antibiotics and vaccines are discussed, providing insights into stability, sources, and delivery methods. Findings discussed in this review could be applied to the development of safer, more effective adjuvants, that could expand the use or repurpose current antibiotics or improve vaccination results in future clinical trials.
Subacute toxicity of isoliquiritigenin-zein phosphatidylcholine nanoparticles on biochemical, hematological, and histopathological parameters in Sprague-Dawley rats
Authors: Yang Ke , Ganesan Kumar , Gao Fei , Xie Chunguang , Chen Jianping
Published: April 2024

Aim: Isoliquiritigenin (ISL) is a natural flavonoid found in many natural plants, which exhibits numerous pharmacological properties including anti-inflammatory, antioxidant, antitumor, and antiviral activities. However, the low bioavailability and stability of ISL limit its application in clinical practice. To overcome these limitations, ISL-zein phosphatidylcholine hybrid nanoparticles (ISL@ZLH NPs) have been developed to improve the bioavailability and stability of ISL. The present study aimed to evaluate the acute and subacute toxicity of ISL@ZLH NPs in Sprague-Dawley (SD) rats.
Methods: The ISL@ZLH NPs were prepared by the solvent evaporation method. The acute toxicity was evaluated by administering a single dose of 110 mg/kg and 160 mg/kg of ISL@ZLH NPs extracted in distilled water via oral gavage in rats and mice, respectively. The subacute toxicity was evaluated by administering doses of 27.5 mg/(kg∙day), 55 mg/(kg∙day), and 110 mg/(kg∙day) of ISL@ZLH NPs for 30 days and 90 days. The biochemical, hematological, and histopathological parameters were analyzed in both studies.
Results: In the acute toxicity study, no mortality or significant changes in the biochemical and hematological parameters were observed in both Kunming (KM) mice and SD rats. In the subacute toxicity study, no toxic reactions were observed in both species at all doses tested. Moreover, no significant changes in the biochemical, hematological and histopathological parameters were observed in both species.
Conclusions: The results of this study suggest that ISL@ZLH NPs are safe and non-toxic in both KM mice and SD rats. The nanoparticles (NPs) did not induce any adverse effects on the biochemical, hematological, and histopathological parameters in both acute and subacute toxicity studies. These results indicate that ISL@ZLH NPs are safe for prolonged consumption. Further studies are needed to evaluate the long-term toxicity and efficacy of these NPs in vivo.
Chronic diarrhea secondary to intestinal spirochetosis, should we think about it?
Authors: Calvo Bernal MM , Rodriguez Mateu A , Gil Belmonte MJ
Published: April 2024

Human intestinal spirochetosis (HIS) is defined as a colonization of the apical membrane of the colonic mucosa and the appendix by spirochetes. It is a very rare finding, being more common in some populations (individuals living in villages and peri-urban environments in developing countries, recent immigrants from developing countries, men who have sex with other men and HIV positive patients), but the spirochete rarely is investigated as human enteric potential microorganism.

It is a slow-growing microorganism and has specialized growth requirements, which is why it is not detectable in human fecal samples using routine diagnostic methods. However, it has been histologically identified attached to the colon and rectum in patients with conditions such as chronic diarrhea, rectal bleeding, and/or nonspecific abdominal discomfort.

In this article we present the case of a patient with chronic diarrhea secondary to intestinal spirochetosis, highlighting the importance of considering this etiology in the differential diagnosis.

Suicide is a leading cause of mortality among young people in many countries, making it a serious global public health problem. It is estimated that around 20% of global suicides are due to pesticide poisoning. This study was conducted with an objective to find out the commonest suicidal poison and its demographic distribution. This study was designed on victims of suicidal poisoning brought for medicolegal autopsy at Silchar Medical College and Hospital, Silchar, Assam between 15th October 2017 and 14th October 2022. Required information for the study was gathered from inquest reports, autopsy reports, chemical examiner’s analysis report of viscera and available documents in the departmental records. The collected information was statistically analysed using Microsoft excel version 2019. Out of 64 cases, poison was detected in 33 Cases. Male victims surpassed females with highest number of victims from age group 21-30 years. Most common poisoning agent was organophosphorus compounds. Educational and awareness programs regarding usage and storage of pesticides can become an important step for the prevention of deaths due to poisoning. However more research is needed to better understand suicides involving pesticides in their cultural contexts
Funktionsstrukturierung als Grundlage effizienten Engineerings von Anlagen und Individualprodukten/Functional structuring as basis for efficient engineering of plants and individual products
Authors: Krüger Lorenz , Saske Bernhard , Paetzold-Byhain Kristin
Published: April 2024

Im Anlagenbau ist jedes Produkt ein kundenspezifisches Unikat. D. h., für jede Anlage muss der gesamte Entwicklungsprozess durchlaufen werden, obwohl es einen hohen Anteil Wiederholkomponenten gibt. Etablierte Methoden, sie beim Produktdatenmanagement (PDM) zu identifizieren, basieren auf der Auswertung von Baustrukturen und schlagen im Anlagenbau fehl, da gerade die Baustruktur einmalig ist und sich nie wiederholt. Dagegen sind Funktionsstrukturen wesentlich kundenunabhängiger und liefern dennoch eine vollständige wie detaillierte Produktbeschreibung. Dieser Beitrag unterbreitet einen Kernmodellvorschlag, um im PDM die Funktionsstrukturierung zur Teilewiederholung einzusetzen.

Stewards of Society: Preparedness and Perceptions Among the Unsung Heroes of Public Health Service Delivery
Authors: Camarillo Earlene , Barsky Christina
Published: April 2024

Front-line public health workers are essential to protecting the health of the public, particularly during widespread public health emergencies. Local public health workers were instrumental in mitigating the spread of the coronavirus pandemic through their efforts to contract trace, disseminate tests and vaccines, and educate the public about the dynamic state of the crisis. Yet, reports indicate that the public health workforce has been shrinking for some time. Recent studies indicate more than one-quarter of those serving in public health roles hope to leave the profession within one year because of factors such as stress and burnout. Few studies examine the perceptions of local health workers or the impacts that multi-level governmental responses have on their ability to do their jobs. Having a strong public health workforce is essential for a thriving society, so addressing this gap and identifying solutions are important steps towards identifying solutions for slowing the exodus of public health workers from the field. Through analysis of original survey data of front-line workers mid-pandemic in two western states, this project examines perceptions regarding factors which contribute to added stress and burnout. Findings indicate that workers felt relatively prepared to address a public health crisis, but institutional factors, such as changing job responsibilities, competing governmental directives, and limited resources, may contribute to ongoing feelings of burnout. To address these concerns, decision makers need to provide more resources and have a clear strategy of communication to mitigate conflicting governmental directives.

Published: April 2024

Este estudio examina la inclusión de la historia y cultura afroecuatoriana en el currículo de Estudios Sociales en las escuelas ecuatorianas, a través de un enfoque mixto que combina el análisis documental del currículo oficial, entrevistas a docentes y cuestionarios a estudiantes. Los resultados revelan una presencia limitada de estos temas en el currículo, con un enfoque predominantemente histórico-cultural y una menor atención a perspectivas críticas y reflexivas sobre las relaciones de poder y la discriminación. Los docentes manifiestan un conocimiento limitado y una falta de formación y recursos específicos para la enseñanza de la historia y cultura afroecuatoriana, mientras que los estudiantes muestran niveles variables de comprensión y valoración, con diferencias según el tipo de institución educativa. Se encuentra una correlación positiva entre la comprensión y valoración de estos temas y las actitudes hacia la diversidad cultural y las relaciones interculturales. Se concluye que, a pesar de los avances, existen desafíos y oportunidades para fortalecer la inclusión de la historia y cultura afroecuatoriana en el currículo, a través de una perspectiva más transversal, crítica y transformadora, que promueva el reconocimiento, el diálogo y la justicia social.

Penerapan Logika Fuzzy Sugeno Untuk Optimasi Kualitas Tempe Pada Proses Fermentasi
Authors: Rahman Sari Arfani , Sriani
Published: April 2024

Determining the amount of tempeh production can be done by industries or businesses that process soybeans into tempeh, which is a source of nutrition and food for the Indonesian people. Apart from being easy to get, tempeh is also one of the favorite foods among all groups. In producing tempeh, it is certain that the tempeh manufacturing industry also carries out a fermentation process every day to produce a lot of tempeh, apart from that, the process requires maximum manufacturing so that the quality of the tempeh is maintained until it reaches consumers. However, if it is not optimal, the quality of tempeh and the entrepreneur will lose profits. Therefore, tempeh quality was optimized. In order to reduce the impact of poor quality during the manufacturing process, it is necessary to calculate the prediction factors for the impact of poor quality, namely by using the Sugeno fuzzy logic method. Where fuzzy can be relative and can provide solutions to problems encountered in the production process. Optimizing the quality of tempeh from several variables can be determined by a MAPE value of 7.02% according to the predicted value table of 7.02% and this includes good research and is very efficient. Based on these problems, the author models an application system built with Matlab software.

Prediction system for the price of gold in Indonesia using a machine learning algorithm, namely the Gated Recurrent Unit (GRU), with influencing variables being the closing price of PT. Aneka Tambang's stock and the closing price of the US dollar exchange rate. The main objective of developing this system is to provide accurate and reliable information about the gold price trends for the next 7 days to the general public, investors, and other relevant parties. The dataset used consists of historical data for the closing prices of gold, the closing prices of PT. Aneka Tambang's stock, and the closing prices of the US dollar exchange rate, obtained from Yahoo Finance's website from January 2018 to October 2023. The dataset was pre-processed by extracting the dates from the three data sources used. In the results of training the GRU model for prediction, the best results were achieved with hyperparameters of 70% training data, 30% testing data, a timestep of 20, 50 epochs, and a batch size of 16, with an R-Squared value of 0.97, an MAE of 300.17, and an RMSE of 17.33. With the development of this system, it is expected to provide guidance for the general public, investors, and related parties in making timely decisions regarding gold purchases and to enhance their understanding of gold price movements in Indonesia.

Vehicles using fuel oil that is converted into mechanical energy were introduced in 1891 by John W. Lambert in America. But with this, the level of air pollution caused by exhaust emissions has become a problem today, until environmentally friendly engine innovations appear. The beginning of the development of these innovations was marked by hybrid technology cars. This technology has not completely abandoned the use of oil as fuel. In general, these vehicles are known as HEV or Hybrid Electic Vehicles. Then came a car that was entirely with an electric motor drive or EV or Electric Vehicle. Although the technology is considered environmentally friendly, on the other hand it does not make all elements of society accept any changes, especially in fuel oil engines to electric motors. With these changes, there are pros and cons that are the focus of researchers by utilizing sentiment analysis which is a Natural Language Processing (NLP) scientific family to analyze what aspects make society pro or con to the emergence of environmentally friendly vehicles. Data collection in this study took from YouTube comments in the form of Indonesian text data carried out using Python programming language and Long-Short Term Memory (LSTM) as an algorithm for analyzing public opinion. The dataset was divided into training data and test data with a ratio of 67:33, The results showed that the model can be used on Indonesian text data well. Then for the process of accuracy test data 63%, then macro avg precision 62%, macro avg recall 60%, macro avg f1-score 60%, weighted avg precision 62%, weighted avg recall 63%, weighted avg f1-score 62%, roc_auc 81%. In this study, it can also be seen that the topic of discussion that often arises, namely prices in all classes. However, negative sentiment is more than other sentiment classes, one of which is due to electric car manufacturers so it is very necessary to pay attention to stakeholders regarding prices that are suitable for the Indonesian market.

Indonesia has recently been enlivened by the data breach case that hit Bank Syariah Indonesia (BSI) in May 2023, this has invited many responses from the public with various kinds of responses, especially on Twitter social media. Some people support BSI bank so they can restore the system they have but many criticize and blaspheme bank BSI for not being able to quickly fix its system which hackers compromised. The purpose of this study is to conduct a sentiment analysis to find out the response of the Indonesian people regarding cases of data breaches by bank BSI customers whether positive, negative or neutral. The methods used in this study are the naive Bayes method and the random forest method. Both of these methods have been widely used in the text data classification process and produce high accuracy. The dataset used is community responses from Twitter social media taken by crawling the data totaling 809 tweets. The results of this study are the accuracy of the Naive Bayes method of 74% and the random forest method of 70%.

Os alimentos utilizados no trabalho apresentam classes de toxinas e antinutrientes que são discutidos no texto, quanto a ocorrência e efeitos causados em pessoas alérgicas ou intolerantes como proteínas, glicoalcalóides, glicosídeos cianogênicos, acrilamida e micotoxinas. Além dessa apresentação, a revisão aponta os riscos que dietas veganas podem trazer para adultos e crianças que apresentam restrições no consumo de alguns alimentos em função de alergia ou intolerância.
IGUALDADE NA DIFERENÇA: REPRESENTAÇÕES IDENTITÁRIAS NOS DOCUMENTÁRIOS LIMITADO, EU? E A INTOLERÂNCIA QUE MATA DA TV ALE-RR
Authors: Pinto Sonia Lucia Nunes
Published: April 2024

O presente trabalho busca analisar a TV Assembleia Legislativa de Roraima (TV institucional de caráter público) nas suas produções de sentidos. Para isso, observa-se a construção dos discursos de cidadania e de identidade política inclusiva para além da tela da TV, por meio dos documentários “Limitado, eu?” e “A intolerância que mata”, produzidos pelo jornalista Rubens Medeiros, em 2018. Os aportes teórico-metodológicos utilizados tratam sobre Estudos Culturais (identidade, cultura) e pós-coloniais, meios de comunicação de massa. Até o momento, constatou-se que a construção identitária é resultado das práticas sociais no processo comunicacional, em que os significados são instituídos pela sociedade, como uma visão de si mesma.

One of the operations realized during the production of lecithin is the standardization, which is made by the addition of oil and fatty acid. This study aimed to realize the rheological characterization of the dispersions of soybean lecithin, degummed soybean oil, and fatty acids. The flow curves showed that all dispersions were pseudoplastic fluids, time-dependent viscous flow with thixotropic behavior. Ostwald-De-Weale model fitted properly the shear stress and shear rate data, with values of rheological index and consistency coefficient in the range of 0.73 – 0.97 and 1.02 – 28.32 Pa.sn, respectively. The increase in degummed oil content weakened the pseudoplastic behavior of lecithin formulations. The percentages of thixotropy of lecithin and mixtures ranged from 5.3 to 54.4%, and the addition of degummed oil and fatty acid reduced the thixotropic behavior of crude soybean lecithin. As for color, there were no significant differences between dispersions, with values around 5.0 measured on the Gardner scale.
