Published: July 2023

Bangladesh is a densely populated country in South-East Asia. Increasing population along with increasing development activities lead to exploitation and pollution of water supplies readily available to us. Therefore, water quality indicators are imposed as a global problem to determine its suitability for individual uses as well as to establish major strategies for optimal use of water resources. Failure to ensure safe drinking water with efficient purification systems will leave communities vulnerable to waterborne outbreaks with harmful health conditions. The main motive of this study is to ensure the safety of drinking water quality in Barishal district. The physic-chemical parameters, i.e. pH, turbidity, total dissolved solids (TDS), electric conductivity(EC), iron content, arsenic, chloride, hardness, dissolved oxygen(DO) and biochemical oxygen demand (BOD) for four upazila’s were tested and compared with the Bangladesh standards along with WHO guidelines. The determined value of these tests were within the allowable range according to WHO guidelines and Bangladesh standards. This study assesses the current status of drinking water quality in Barishal district with emphasis on effective purification, disinfection and systematic monitoring services to control water pollution.
Repairability-Based Design of Concrete Structures
Authors: Opabola Eyitayo , Elwood Kenneth
Published: July 2023

Recent earthquakes demonstrated that modern reinforced concrete (RC) buildings (i.e., post-1970s) can satisfy the code-intended life safety performance objectives. However, the accumulated damage in these modern buildings raised concerns about their performance in any future events; contributing to widespread demolition and long-term closure of damaged buildings. The economic and environmental impacts associated with the demolition and long-term closure of modern buildings led to societal demands for improved design procedures to limit damage and shorten recovery time after earthquakes. To address societal demands, this study proposes a repairability-based design approach for structural systems. The proposed approach aims to ensure that, under design-level earthquakes, damaged structural components have sufficient residual capacity to withstand future events without requiring safety-critical repair (the adopted definition of repairability); thereby ensuring the structural systems are safe for re-occupancy and can achieve functional recovery. Firstly, the repairability limit state for RC components is defined using an extensive database of past tests on RC components. Subsequently, component deformation limits are proposed for RC beams, columns, and walls. Furthermore, nonlinear response history and recovery (using the ATC-138 methodology) analyses of four archetype frame buildings, designed per New Zealand standards to different beam deformation limits, are used to assess the seismic performance and capability of the buildings to satisfy recovery-based performance objectives. By comparing the repairability fragility and functional recovery downtime estimates of the frame buildings for design-level events, it is concluded that it is feasible for the building code to target repairability in the design-basis earthquake in addition to collapse prevention in MCE.
Therapie und Outcome gynäkologischer Tumore bei HIV-infizierten Patientinnen
Authors:   , Albrecht Noelle-Dominique
Published: July 2023

Sowohl die Lebenserwartung als auch die Prävalenz HIV-infizierter Patient*innen ist stetig ansteigend,aufgrund der HAART und durch verbesserte diagnostische Methoden. Nicht-AIDS-definierenden Erkrankungen sind heutzutage die führenden Todesursachen. Durch verzögerte Diagnosestellung und zurückhaltenden Therapien gynäkologischer Malignome ist die Prognose im Vergleich zur Normalbevölkerung schlechter. In dieser retrospektiven Fall-Kontroll-Studie des Universitätsklinikums Frankfurt am Mains wurden die Therapie und das Outcome gynäkologischer Malignome von 23 HIV-infizierten Patientinnen aus den Jahren 2009-2019 mit einer Kontrollgruppe aus dem gynäkologischen Krebszentrum der Klinik Essen Mitte verglichen, um herauszufinden, inwiefern eine HIV-Infektion das Outcome der Patientinnen beeinflusst. Das gynäkologische Malignom, dominierend das Zervixkarzinom, trat durchschnittlich ein Jahrzehnt nach der HIV-Diagnose auf. Im Unterschied zu anderen Studien, ist unser Kollektiv überwiegend hellhäutig. Ein bekannter Drogenabusus ist häufig und zusammenhängend mit weiteren Koinfektionen. Die HIV-Erkrankung ist bei mehr als der Hälfte der Patientinnen bereits fortgeschritten, jedoch ließ sich kein Zusammenhang zwischen dem Auftreten gynäkologischer Malignome und einer CD4-Zellzahl <500 CD4-Zellen/µl nachweisen. Die antiretrovirale Therapie entsprach größtenteils nicht den aktuellen Leitlinien. Bis auf fünf Frauen wurden alle Frauen leitliniengerecht therapiert. Eine Korrelation zwischen der Therapie und der Tumorentität, der CD4-Zellzahl, dem Alter oder dem Stadium des Malignoms konnte nicht gezeigt werden. Insgesamt liegt die 5-Jahresüberlebensrate der Kohorte bei 74.8%. Eine nicht leitliniengerechte Therapie ist nicht direkt mit einem schlechteren Outcome verbunden, jedoch mit einem weitaus kürzeren Follow-Up-Zeitraum von durchschnittlich 0.22 Jahren im Vergleich zu 4.85 Jahren bei leitlinienkonform therapierten Patientinnen. Es liegt ein statistisch signifikanter Unterschied zwischen der Kontrollgruppe und unserer Kohorte vor, sodass angenommen werden kann, dass bei Vorliegen einer HIV-Infektion die Therapie des gynäkologischen Malignoms häufiger nicht leitliniengerecht ist. Bislang existieren nur wenige Studien, die die Therapie und das Outcome gynäkologischer Malignome bei HIV-infizierten Patientinnen untersuchen. Die Interaktion einer ART mit antineoplastischen Medikamenten und die Anwendung von Checkpointinhibitoren und einer „targeted therapy“ sollten Gegenstand weiterer Untersuchungen sein. Dafür sollten HIV-Patientinnen in Therapiestudien inkludiert werden, sodass geeignete Leitlinien erarbeitet werden können.
In Vivo Anti-Vibrio Evaluation of Sponge-Associated Bacteria on the Survival Rate of Litopenaeus vannamei Infected with Pathogenic Vibrio Species
Authors: Jepri Agung Priyanto  , Galuh Adhiyaksa Ashari  , Munti Yuhana  , Aris Tri Wahyudi
Published: July 2023

Sponge-associated bacteria are considered a rich source of bioactive compounds particularly to reduce the risk of Vibrio harveyi and Vibrio parahaemolyticus infection. The present study aimed to analyse the effectiveness of 19 isolates to control Vibrio infection in vivo. All 19 isolates displayed a non-pathogenic characteristic on shrimps (cell density of 106 cells/mL) as analysed using the pathogenicity test. The mortality caused by both Vibrio spp. on 50% of the shrimp population (LC50 value) had a cell density of 105 cells/mL as determined using the proportion interval method. On the basis of the challenge test, all isolates improved the survival rate of infected shrimps in diverse effectivities up to 89%, which was nearly 30% higher than the infected control. Two isolates coded as D6.9, and P5.20 reduced shrimp mortality after infection with Vibrio spp. 16S rRNA-based identification showed these isolates were closely similar to different genera of Bacillus and Staphylococcus. The extract derived from the most prospective isolate, D6.9, was dominated by 1-hydroxy-6-(3-isopropenyl-cycloprop-1-enyl)-6-methyl-heptan-2-one, hexadecanoic acid, 4-epicyclomusalenone [(24S)-24-methyl-28-norcycloart-25-en-3-one], and 2,4-dimethyl acetoacetanilide. This observation suggested these isolates characterised by in vivo anti-Vibrio activity need to be further developed as biocontrol candidates.

Published: July 2023

The ecosystem of Bandon Bay, in the Gulf of Thailand (GoT), has been impacted since 2007 by the continued stocking of larval blue swimming crab Portunus pelagicus, also called a crab bank. In this study, the food web in the Bay was modelled using Ecopath software to compare the trophic status, interaction and energy flow among the components in the system in 2007 and 2016 (i.e., before and 10 years after the crab bank intervention). The models were based on data collected from trawling. Twenty fish and shellfish components were used in the 2007 model, while 22 were used in the 2016 model. A significant increase in biomass was found in blue swimming crab, but biomass declined for other demersal fishes, cephalopods, and Penaeid shrimps. The production/biomass ratios of most components were higher in 2016 but the consumption/biomass ratios were relatively unchanged. The ecotrophic efficiency indicated that shellfishes were more exploited than fishes. Changes in most of the ecological indices revealed higher maturity and stability after 10 years of crab bank operation. The mixed trophic impact indicated bottom-up regulation, and that the increase of blue swimming crab negatively impacted only Mantis shrimp. Overall, the results indicate positive impacts of the crab bank intervention.
Histopathological Alterations in Gills, Liver and Kidney of African Catfish (Clarias gariepinus, Burchell 1822) Exposed to Melaleuca cajuputi Extract

Published: July 2023

This study evaluated the histopathological changes in the gill, liver and kidney of African catfish (Clarias gariepinus) intoxicated with a sub-lethal dose of Melaleuca cajuputi leaves extract (MCLE) for 96 h. The acute toxicity test has been determined previously with a value of 96-h LC50 = 127 mg/L, hence the selection of sub-lethal ranges from 60 mg/L to 160 mg/L of MCLE. Degenerative alterations were prominent in all tested organs, particularly after exposure to a high concentration of MCLE. Gill exhibited haemorrhage, epithelial lifting, lamellar disorganisation, and necrosis after exposure to a high MCLE concentration. Alterations in the liver include congestion, hydropic degeneration, and vacuolation, whereas lesions in the kidney were pyknosis, vacuolation, hydropic degeneration, and tubular necrosis. The obtained data showed that the organs experienced severe changes proportional to the increase in MCLE concentration. In addition, fish exposed to higher concentrations than the LC50 value experienced irreversible lesions. The present study suggests that the use of MCLE below the LC50 is recommended to avoid severe alterations to organs, particularly in African catfish. This study demonstrated that the use of MCLE above the LC50 promotes severe damage to the gills, liver and kidney of African catfish. However, further investigations are needed to define the causing-mechanisms underlying these effects.

Published: July 2023

Nas últimas décadas o entendimento sobre o desenvolvimento foi transformado com a caracterização da sua dimensionalidade e associação às condições presentes nos territórios. Uma das dimensões constitutivas do desenvolvimento é a cultura, particularmente o patrimônio territorial e elementos associados, cuja compreensão é fundamental para o desenvolvimento do território. Tem-se como objetivo caracterizar o delineamento metodológico correspondente à trajetória metodológica pertinente à identificação dos componentes da dimensão cultural que integram o patrimônio territorial. Metodologicamente, foi efetuada uma abordagem qualitativa e exploratória sob a perspectiva teórica, para se chegar na propositura de elaboração do índice. Os resultados demonstram a contribuição da dimensão cultural para o Índice Multidimensional da Ativação do Patrimônio Territorial – Imap –, referência que estabelece variáveis em seis dimensões: produtiva, social, natural, cultural, institucional e humana/intelectual em relação ao território. Conclui-se que a dimensão cultural referente ao Imap corresponde aos seguintes indicadores: multiculturalidade (valores e códigos de conduta); manifestações e equipamentos culturais; estrutura da mídia; e economia criativa. Estes indicadores são instâncias normativas que determinam os valores subjacentes da leitura da ativação do patrimônio de um território, as quais permitem o agregar dos índices identificáveis no processo de pesquisa e do diagnóstico.

A review on larvicidal and repellent effects of Brassica nigra towards malaria mosquito
Authors: Bekele Damtew
Published: July 2023

The efficacy of synthetic insecticides to control malaria vectors is compromised by increased mosquito resistance to insecticides.Furthermore, the use of inorganic insecticides raises serious environmental toxicity concerns. It is hoped that this review wouldincorporate plant-based control tools in modern malaria vector control at the community level. Therefore the use of syntheticinsecticides is the challenge faced for malaria vector control because of the resistance of mosquitoes and their toxicity to theenvironment. Medicinal plants used like Brassica nigra in traditional medicine are promising and largely unexplored sources for thedevelopment of potential new compounds particularly in plant-rich countries like Ethopia.
Newborn Screening for Mucopolysaccharidosis Type I: Past, Present and Future
Authors: Kingma Sandra , Jonckheere An , Roosens Laurence , Eyskens François
Published: July 2023

Mucopolysaccharidosis type I (MPS I) is a lysosomal storage disorder caused by a deficiency of the lysosomal hydrolase α-L-iduronidase. MPS I is characterized by a broad range of disease manifestations. This includes devastating neurocognitive and bone manifestations and a short life expectancy in severely affected MPS I patients. Neurocognitive manifestations are typically limited in more attenuated MPS I, but patients may still suffer from severe somatic and bone manifestations. Severe MPS I patients are primarily treated with hematopoietic stem cell transplantation (HSCT) and more attenuated patients with enzyme replacement therapy. HSCT should be initiated before irreversible disease manifestations, preferably before 9 months, but may be initiated in patients up to 2 years. Early diagnosis of MPS I is challenging at best, and newborn screening (NBS) has already been initiated in several countries to diagnose and treat patients early. This article summarizes the history, benefits, methods and challenges that have to be addressed before NBS can be used most effectively.

Published: July 2023

In this study, Lepidium sativum seeds were collected from the local markets in Baghdad. Zinc oxide nanoparticles were manufactured from the aqueous extract of Lepidium sativum by adding zinc acetate in a green, safe and environmentally friendly manner. The formation of zinc oxide nanoparticles was inferred by changing the color of the extract from white to yellow, and for Detection of biosynthetic zinc oxide nanoparticles Examinations were conducted to detect these nanoparticles, including diagnosis using atomic force microscopy (AFM), which showed that the size of the nanoparticles (13) nm and the surface roughness (80.51) nm compared with the aqueous extract, which amounted to (23) nm and (57.22) nm respectively. The diagnosis using UV rays showed a peak absorption of nanoparticles at 350 nm compared with the aqueous extract, which reached 248 nm. As for the scanning electron microscope (SEM) examination, the nanoparticles' size ranged between 46.97 - 81.07 nanometers, compared with the aqueous extract, which reached 676 - 591.8 nanometers. To determine the toxic or inhibitory effect against A375 cancer cells and HdFn normal skin cells, MTT cytotoxicity assay was performed for aqueous extract and zinc oxide nanoparticles. The results showed that the aqueous extract was effective against the cancerous cell line A375, as the viability of the cells decreased with the increase in the concentration of the aqueous extract. The IC50 ratio was equal to 140.0 mg/ml for the A375 cancer cells, and the IC50 ratio was equal to 179.9 mg/ml for the normal HdFn cells. As for zinc oxide nanoparticles, the effectiveness was more substantial than that of the aqueous extract, and the vitality of cells was reduced in the cancerous line A375. The normal line HdFn, the higher the concentration of nanoparticles, and the IC50 ratio was equal to 59.46 mg/ml for the cancerous line. The IC50 ratio was equal to 196.9 mg/ml for the normal line.

Based on the actual cities in China in the new century after reform and opening up, one period of time which born at the end of Cultural Revolution, we tend to interrogate the urban novel for corresponding to rural novel, is a reflection on cultural integration and de-urbanization. From three aspects including the transcendence of modernity, the urban and rural spatial narrative of new century novels and the presentation of urban landscapes, considering the recursive reality from rural China to urban China, we attempt to explore how the novel text represents China's urbanization, dig out the manifestations of human’s survival in the process of urbanization in China in the new century after seeking roots in rural areas, thus mirroring the mixed urban habitats of multiple ethnic groups in Guangxi.
Prebióticos orales: alternativa para el tratamiento y prevención de caries
Authors: Sánchez Medina Juan Gerardo , Aranda Romo Saray , Martínez Martínez Rita Elizabeth , Comas García Mauricio , Aragón Martínez Othoniel Hugo
Published: July 2023

La caries es la enfermedad bucal más frecuente a nivel mundial. Se origina por una producción excesiva de ácido, que se forma cuando las bacterias que colonizan la boca digieren los azúcares presentes en la dieta. Sin embargo, existen azúcares que las bacterias orales no pueden digerir, que son conocidos como prebióticos. Los prebióticos son compuestos que pueden ser utilizados selectivamente por los microorganismos del huésped, en especial los intestinales, y le confieren un beneficio para su salud. Se encuentran presentes de forma natural en alimentos como la leche, miel de abeja, hortalizas, verduras, frutas, cereales, legumbres y frutos secos; también se pueden obtener mediante síntesis química o enzimática. En los últimos años, han surgido nuevas estrategias terapéuticas y preventivas para la caries, enfocadas en utilizar prebióticos en productos de higiene oral, alimentos y suplementos; sin embargo, no se trata de una práctica común en la odontología. Es importante conocer más acerca del beneficio que los prebióticos ofrecen a la salud oral de los individuos, para favorecer su utilización de manera rutinaria como complemento a los tratamientos dentales.

Published: July 2023

Los plaguicidas se emplean en todo el mundo para garantizar la demanda de alimentos diarios  y la protección de la salud humana, evitando la propagación de organismos transmisores de enfermedades. A pesar de sus propiedades beneficiosas, son perjudiciales para los seres vivos que se exponen diariamente a pequeñas cantidades de estas sustancias, ya sea por el consumo de alimentos contaminados o por la deficiente manipulación de los productos para el control de plagas utilizados en los hogares. Además, la exposición prolongada a estas sustancias se ha asociado a enfermedades crónicas y agudas, como el cáncer, enfermedades neurodegenerativas, respiratorias, reproductivas, trastornos en el desarrollo y trastornos metabólicos. En la actualidad, el desarrollo de plaguicidas menos tóxicos y biodegradables es un tema muy importante en todo el mundo. En este artículo se muestra el papel de la naturaleza química de los pesticidas y sus efectos debido al uso excesivo y prolongado. Alternativas como los aceites esenciales podrían reducir los efectos nocivos para el medio ambiente y la salud humana provocados por los pesticidas.
Hacia una extracción semiautomática de metáforas conceptuales en un corpus de economía a partir del procesamiento de lenguaje natural
Authors: Nieves Uribe Stephany , Molina Mejía Jorge Mauricio
Published: July 2023

Este artículo plantea el fenómeno lingüístico de la metáfora conceptual aplicado al dominio de la economía desde la perspectiva de la lingüística computacional y de corpus a partir del análisis de n-gramas y colocaciones. Para tal fin se ha constituido un corpus de artículos del campo de la economía, el cual se encuentra dividido en dos subcorpus, ambos representados por revistas académicas en dicha área. El análisis textual del reconocimiento automático de metáforas se realizó mediante herramientas y programas informáticos que tienen como finalidad el procesamiento de lenguaje natural, entre estos, algunas librerías especializadas de Python y la herramienta LancsBox. La idea consiste en verificar una hipótesis inicial, según la cual en el discurso empleado por los economistas se tiende a utilizar, en gran medida, metáforas conceptuales que ayudan a comprender aquellos fenómenos ligados al tema de la economía, las cuales subyacen claramente dentro de las publicaciones académicas. Los resultados obtenidos ofrecen un acercamiento a la visualización de las metáforas conceptuales más utilizadas en el campo económico, validando la hipótesis inicial.
Validación de una escala de sobremerecimiento (entitlement) laboral en la población mexicana
Authors: Ortiz Mendoza Oscar Eliud , Madero Gómez Sergio Manuel
Published: July 2023

Recientemente se ha observado un incremento del entitlement, sentido de merecimiento excesivo o sobremerecimiento, así como de los efectos que produce en diferentes contextos como el familiar, escolar y laboral. A pesar de que consciente o inconscientemente se han realizado acciones para gestionarlo, no siempre se cuenta con instrumentos que permitan cuantificar sus efectos, y gestionarlos. La presente investigación pretende obtener un instrumento para medir el entitlement laboral que muestre evidencia de confiabilidad y validez para la población mexicana, basado en el instrumento propuesto por Westerlaken et al. (2017). Se muestra evidencia de que luego de algunos ajustes se alcanzó un instrumento válido y confiable, además de mostrar que el sobremerecimiento laboral es un constructo diferente al sobremerecimiento psicológico, lo que resulta de utilidad para justificar la medición de este constructo, pues es el paso inicial para buscar la forma de gestionarlo.
Organización industrial de la banca, regulación financiera y antimonopolios
Authors: Betancourt Gomez Michel Eduardo
Published: July 2023

El objetivo de este artículo es examinar teóricamente la relación entre la regulación prudencial y antimonopolios de los bancos. Para esto se elabora un modelo teórico donde se consideran diferentes situaciones de regulación prudencial y se evalúan sus repercusiones sobre el poder de mercado y la organización industrial de los bancos. Cuando el poder de mercado es elevado significa que la regulación antimonopolios está siendo poco efectiva y, por lo tanto, existe poca competencia. Los resultados teóricos permiten concluir que el poder de mercado de un banco es más elevado cuando la regulación prudencial es rígida, lo que implica que existe un conflicto entre la regulación prudencial y la regulación antimonopolios. Por último, se ofrece evidencia empírica de esta situación para el caso de México y se propone un nuevo esquema de regulación para solucionar esta inconsistencia.

On the prediction of source code design problems: A systematic mapping study
Authors: Silva Robson Keemps , Farias Kleinner Silva , Kunst Rafael
Published: July 2023

Context: Nowadays, the prediction of source code design problems plays an essential role in the software development industry, identifying defective architectural modules in advance. For this reason, some studies explored this subject in the last decade. Researchers and practitioners often need to create an overview of such studies considering the predictors of design problems, their main contributions, the used prediction techniques and research methods. Problem: However, the current literature remains scarce of studies proposing a detailed mapping of studies already published.

The increase in the cutting temperature during milling has harmful effects which negatively affect the technical and economic machining characteristics such as: residual stresses, dimensions of machined parts and tools life. The nature of milling operations and the tool geometry make it difficult to predict or measure the temperature during the machining process, which is why great attention has been paid to measurement and prediction methodologies of cutting temperature during milling. In this work, a new intelligent identification technique of the cutting temperature based on the fuzzy set theory has been proposed to replace the strategy based on the operator qualification. This technique uses a fuzzy multiple input inference system to determine the influence of the cutting parameters on the cutting temperature. The fuzzy modeling is based on an experimental database resulting from the non-contact measurement of cutting temperature using an infrared camera with an emissivity setting adapted to the material. The results of the fuzzy system show that the fuzzy model is able to specify results providing a very good correlation between the experimental data and those predicted. The average error of the model was approximately 2.242%. The parameters used for the validation of the model were different from the data used for the construction of the fuzzy rules. The results showed that the most important parameter on the cutting temperature is depth of cut. The results obtained in this paper show that the developed model can be applied to predict the cutting temperature with precision during the milling process.

Published: July 2023

Diabetes mellitus patients are at an increased risk of cardiovascular illness, and cardiovascular complications are the primary cause of morbidity. Diabetes is linked to both morbidity and mortality. Type-2 Diabetes causes a prothrombotic state that leads to acute coronary syndromes by causing endothelial damage and lowering antiaggregant factors like nitric oxide and prostacyclin, as well as increasing thrombotic substances like fibrinogen and factor VII, and suppressing fibrinolysis with factors like plasminogen activator inhibitors. The accurate identification and diagnosis of CVD (Cardio Vascular Disease) is dependent on the correct detection of the ECG signal from the heart. The ECG signal is extremely important in the early detection of cardiac problems. The ECG signal of diabetic individuals offers vital information about the heart and is one of the most important diagnostic tools used by doctors to identify cardiovascular disorders. The time gap between two consecutive QRS complexes appearing contiguous in an ECG is known as heart rate.  The most appealing feature is that HRV (Heart Rate Variability) measurement is non-invasive and repeatable. A number of machine learning techniques have been proposed for the non-invasive automated identification of diabetes. This paper discusses innovative methods for analyzing electrocardiogram (ECG) signals in order to extract important diagnostic information. The ECG signal is first treated using a dual tree complex wavelet transform (DTCWT-SG) with threshold method. Subsequently, the features are extracted from detailed coefficients of DTCWT-SG filter, Eigen vectors by minimum normalization method and Rajan Transform. Main key features are extracted using these three methods. These features are classified and analyzed by different machine learning classifiers. The proposed approach was tested on DICARDIA, MIT-BIH and Physionet database and the performance analysis shows that the hybrid Recurrent Neural Network (RNN) (LSTM+GRU Gated Recurrent Units) achieves better prediction of 98.8% compared to state of art techniques.
Heavy metals and sulfate removal from acid mine drainage using steel mill slag in a rotational mixing device

Published: July 2023

The steel mill slag (SMS) production in converter furnaces is one of the main by-products generated during steel production. This waste material is usually composed of different metal oxides that include basic cations such Ca, Mn, and Mg. These cations can favor alkalinity and a heavy metals removal when they are partially dissolved in a contaminant solution such as acid mine drainage (AMD). This work aims to study the potential use of SMS produced in converter furnaces in the mining-steel region of Boyacá- Colombia as an alternative to pre-treat AMD produced by coal mining in the zone. The SMS were separated into two particle sizes by screening, and these were put in contact with AMD samples in a rotational mixing system for 36h. The pH, total Fe (Fe2+, 3+), SO42-, and heavy metals concentration were analyzed at 0h, 12h, 24h, and 36h time intervals. The final results show that SMS produced in the region is an optimal low-cost alternative to treat AMD, allowing complete heavy metals removal in the firsts 12h of treatment. Furthermore, Fe and SO42- removal were observed, reaching 99.9% and 85%, respectively, at 36h. The application of rotational mixing allows complete mixing between AMD and SMS, reducing the possible precipitates adhesion on the surface, limiting the reactivity losses. This mixing treatment device favors a continuous use, avoiding the application of cleaning stages that could be required in the future for optimal functioning.

Through the descriptive analysis on the Open Data of the Costa Rican Judicial Power, alarming results are reflected in the number of complaints imposed in the Judicial Investigation Organism (OIJ), exceeding fifty thousand complaints in 2019. Based on those numbers, the objective for this research is to generate a data analysis model that allows to potentiate these statistics and to indicate in advance the regions with the most remarkable propensity to suffer crimes in the next five years, to promote the proactivity of both the citizen and the police to be alerted and to avoid upcoming crimes. Statistical prediction models are used to prove mathematical methods applicable to the data obtained and their behavior during 2015-2019. The analysis reflects the need to apply the simple linear regression algorithm to the developed solution available to all Costa Ricans on the Tableau Public website. The results show pessimistic predictions for the country, especially in the Greater Metropolitan Area (GAM); the behavior of crimes will significantly impact this area, which indicates the need to establish police strengthening programs improvements in education and employment to counter the potential crimes projected for the next five years

Published: July 2023

Abstract: The adoption and utilization of Internet of Things (IoT) technologies such as IoT Platforms, 5G, connected sensors, WAN, etc mostly come with numerous, seemingly complex and expensive challenges for institutions and organisations, particularly in developing countries as they work to fill their fair share of the global IoT market. Multi-criteria decision support systems (MCDSS) can be indispensable tools for evaluating and prioritizing these complex competing difficulties by multistakeholder decision makers. While eliminating conventional decision problems such as, human biases, time consumption, cost of decision, etc, MCDSS make it possible for companies to concentrate on solving challenges which their limited resources can cater for. This study presents an approach for design and implementation of a prototype MCDSS for prioritizing challenges that institutions and organizations face while adopting and utilizing IoT technologies using Fuzzy Analytic Hierarchy Process (FAHP) methodology. ASP.Net model View controller (MVC) framework and C Sharp programming Language was used for the GUI and the Logic development. The system's default IoT challenges and dataset were adapted from the works of A.K. Mohammadzadeh (Baseline dataset). The system usability test result obtained shows that the system is friendly and usable. The output weights and rating of the IoT technology adoption challenges/sub-challenges exhibit over 80% similarity when compared to the Baseline dataset. Further studies are recommended to make the system a

Application of Computational Analysis to Identify Housing Discrimination in 21st Century United States
Authors: Suen Alexander , Ghosh Aditi
Published: July 2023

Abstract: Redlining is a term for race-based discriminatory acts in real estate. While this practice has been outlawed in modern America, the effects remain evident today’s society. The importance of this research is to determine if redlining is still prevalent in America and causing some racial groups to be more likely to be denied home loans over others. This paper analyzes the lasting impacts of housing discrimination in the United States by using data science applications and uses machine learning models to predict whether a loan request will be accepted or denied. We are analyzing loan approval and denial over the past decade by utilizing census data provided by the Home Mortgage Disclosure Act from the United States government. We are determining whether Black Americans and other ethnic minorities are disproportionately denied loans even with similar loan applications as other races. In other words, are they still being redlined and discriminated against based on their race. Our research revolves around the entire nation, from California to Alabama to Illinois to Michigan to determine if redlining is continuously occurring in such places and to predict loan acceptance. We determined that race was not a major factor in home loan decisions, and applicant income, along with loan amount, took precedence
