Published: April 2024

Calcination temperature is a crucial parameter that can be easily controlled to induce a change in material properties. Herein, iron tungstate (FeWO4) was synthesized via a hydrothermal method using iron(II) sulfate heptahydrate and sodium tungstate dihydrate as precursors and calcined at the temperature between 300 oC and 700 oC. With increasing calcination temperature, the saturation magnetization of FeWO4 nanoparticles decreased from 6.6 emu/g for FeWO4 to 0.4 emu/g for FeWO4_700, whereas their band gaps increased from 1.95 eV for FeWO4 to 2.20 eV for FeWO4_700. More crystallinity and crystal defects, and morphological changes at higher calcination temperatures contributed to varying magneto-optical properties of FeWO4 nanoparticles.

Authors: Fajdek-Bieda Anna , Wróblewska Agnieszka
Published: April 2024

This paper presents the results of studies on the transformation of geraniol (GA) in the presence of the natural mineral bentonite. The paper determines the influence of temperature, catalyst content, and reaction time on the course of the process. In order to determine the most favorable process conditions, the catalytic tests were carried out without solvent and under atmospheric pressure. Three functions were chosen to determine the most favorable process conditions: GA conversion and the selectivities of the main products: linalool – LO and beta-pinene – BP. In addition, the paper optimize GA transformation process based on response surface methodology (RSM). The impact of the most relevant process indicators was presented. For all factors of the method, their effects on all primary parameters were determined in the form of second-degree polynomials, and such process conditions were determined to achieve their maximum.

Published: April 2024

The present review handles the main characteristics of iron oxide reduction and its industrial applications. The reduction of iron oxide is the basis of all ironmaking processes, whether in a blast furnace or by direct reduction and/or direct smelting processes. The reduction characteristics of iron ores control the efficiency of any ironmaking process and the quality of the produced iron as well. Many controlling parameters should be considered when discussing the reducibility of iron ores such as equilibrium phase diagrams, reduction temperature, pressure, gas composition, and the nature of both iron ores and reducing agent. The different factors affecting the main routes of ironmaking will be highlighted in the present review to give a clear picture for each technology. Moreover, further innovations regarding the reduction of iron oxides such as reduction by green hydrogen will be discussed.
Synthesis, structural, thermal, and morphological characterization of Ru(III) complex with gatifloxacin and its utility to obtain RuO2 nanostructures
Authors: Althubeiti Khaled
Published: April 2024

In this work, the reaction between the drug gatifloxacin (as a ligand) with Ru(III) ions was investigated and the resulting complex was structurally and morphologically characterized. The structural properties of the complex were assessed using elemental analyses, molar conductance, thermogravimetry, UV-Vis, and IR spectroscopies, where the morphological characteristics were evaluated using SEM-EDX and XRD methods. The analyses suggested that two ligand molecules were coordinated to the Ru(III) ion via the nitrogen atoms of piperazine rings. The complex was formulated as [Ru(L)2(Cl)2]Cl, where the Ru(III) ion has a six-coordinate mode, and the coordination sphere is complemented by chlorine atoms. The interaction of the ligand with the Ru(III) ions leads to the product having an organized smooth plate-like structure with a main diameter of 39.42 nm. The RuO2 oxide in the nanoscale range was generated by the thermal decomposition of the [Ru(L)2(Cl)2]Cl complex at 600 oC for 3 hours. SEM micrographs indicated that the RuO2 material possesses uniform and organized microstructures with many internal cavities enabling it to be used as a catalyst for the heterogeneous degradation of dyes and organic pollutants.

Fallos en el mercado de intercambio de datos entre empresas (B2B) y medidas para abordarlos desde la regulación y los remedios de competencia: una perspectiva europea de lege lata y de lege ferenda
Authors: Olmedo Peralta Eugenio
Published: April 2024

El acceso a datos resulta crítico para el desarrollo de productos y servicios que resulten competitivos en el mercado digital. Sin embargo, su generación y captación se somete a dinámicas que llevan a la acumulación de datos en manos de pocas empresas que los acaparan. A pesar de que los datos están llamados a ser compartidos e intercambiados entre las empresas, se aprecian importantes fallos de mercado que impiden el desarrollo de un mercado interempresarial de datos eficiente. Ello da lugar a un uso sub-óptimo de los datos y a que se desaproveche buena parte de la utilidad social que puede obtenerse de ellos. Las conductas de acaparamiento de datos por las empresas -especialmente cuando se trata de guardianes de acceso- lleva a su infrautilización en detrimento de la competencia en el mercado y de la innovación. En el desarrollo de su Estrategia de Datos, la Unión Europea trata de abordar estos fallos de mercados a través de dos vías: por medio de la regulación del sector digital, y más concretamente estableciendo normas relativas al intercambio de datos. Se imponen así obligaciones y derechos de portabilidad, se fomentan los intercambios y la creación de espacios comunes de datos y pools de datos. A nivel regulatorio, los guardianes de acceso o gatekeepers quedan sometidos a una serie de obligaciones y prohibiciones dirigidas a la apertura del mercado y evitar la consolidación de posiciones indisputables. Complementariamente, las autoridades de competencia pueden también imponer remedios en los expedientes que instruyan ante infracciones antitrust con el objetivo de promover un mercado abierto de datos.
El significado de la educación inclusiva en España y su aplicación al problema de la existencia de “centros especiales” para el alumnado con discapacidad
Authors: Rey Martínez Fernando
Published: April 2024

Los sistemas educativos contemporáneos gravitan sobre el modelo de la “educación inclusiva”, pero este es un concepto que procede de la Pedagogía y tiene un sentido jurídico oscuro y polisémico. El presente trabajo pretende dotar de perfiles jurídicos a la idea de educación inclusiva y de hacerlo, precisamente, en uno de sus campos característicos (pero no único): el de la educación del alumnado con discapacidad. La principal conclusión del estudio es que el sistema educativo español, con su doble red de centros, ordinarios y especiales para alumnado con grandes discapacidades, no es, en realidad, compatible con la Convención de Naciones Unidas de 2006 sobre derechos de las personas con discapacidad.

Voice Recognition to Classify “Buka” and “Tutup” Sound to Open and Closes Door Using Mel Frequency Cepstral Coefficients (MFCC) and Convolutional Neural Network (CNN)
Authors: Laksono Blessius Sheldo Putra , Syaifuddin Tio , Utaminingrum Fitri
Published: April 2024

The consequences of the coronavirus called COVID-19 have been really impactful on society. Many things need to be changed in order to survive this pandemic. People have to avoid physical contact to minimize the probability of getting caught by other people who have been infected. A doorknob has a really big potential to be the medium to spread the virus because the same surface is used by several people. Speech recognition can be used to solve this problem. In this study, Mel Frequency Cepstral Coefficients (MFCC) and Convolutional Neural Network (CNN) are going to be used as the extraction feature and classification method, respectively. We classify the sound signal into two classes (“buka” and “tutup”). People who want to open or close the door just need to say a specific command. This can be helpful to minimize the risk of COVID transmission. A CNN model is developed and fed with an audio file from a curated dataset for training and testing. With this system, we have successfully trained the model with an accuracy of 89% using an epoch of 50 and batch size of 32 as the parameters with a dataset distribution of 8:2 for training and validation. We believe this study will be influential in developing automated door systems using speech recognition, especially in the Indonesian language.

Authors: Panjaitan RE. Miracle , Rahayudi Bayu , Ratnawati Dian Eka
Published: April 2024

The Ministry of Social Affairs of the Republic of Indonesia has Integrated Social Welfare Data called Data Terpadu Kesejahteraan Sosial (DTKS) and uses it as a basis for the distribution of Social Fund Assistance, or Bantuan Sosial (BANSOS). The fact that occurred in the field was that there were many BANSOS recipients who were not impoverished and did not qualify to be the target of this program. One of the reasons is that there are weaknesses in the system that have the potential for data manipulation during the verification and validation processes. Therefore, a system improvement is needed to minimize the possibility of the data being manipulated. This study proposes a digital verification system using Optical Character Recognition (OCR) and reverse geocoding to make sure that the registrant provides their own citizen ID card and their own house address that meet the qualifications. These technologies in the developed mobile app perform address matching between address extracted from citizen ID card and address obtained from reverse geocoding. The results of this application trial achieved a success rate of 95.7%.

Published: April 2024

Advance chemical oil recovery techniques such as low salinity surfactant polymer (LSSP) flooding possibility of increasing oil recovery has been demonstrated by a number of laboratory experiments. In these and related chemical EOR techniques, sodium hydroxide is used to raise the injection solution's pH and decrease anionic surfactant adsorption. However, more precise surfactant adsorption level estimations is needed in the context of low salinity surfactant polymer (LSSP) flooding. Thus, an integrated geochemical framework is developed to understanding of the geochemical interactions between rocks, oil, and brine, as well as surfactants and polymers. Currently, geochemical reactions involving rock-brine, oil-brine, surfactant-brine, and oil-surfactant are considered by surface complexation models (SCM). Here, we take it a step further and apply the surface complexation geochemical reactions for polymers and coupling them for the first time for geochemical modeling of LSSP flooding.

We compared our model with four distinct experimental data sets from the literature and investigated different parameters affecting surfactant adsorption during LSSP flooding. The adsorption of surfactant and effluent concentration was determined accurately by the coupling of polymer-based surface complexation geochemical reactions. Furthermore, we carried out a thorough simulation analysis, and the results show that raising the chemical flood's temperature decreases surfactant adsorption while raising its concentration in the effluent. Additionally, our analysis shows that because there are stronger repulsive forces between the adsorbed species and the rock surface, surfactant adsorption on the rock surface is reduced when the overall salinity of the water is reduced. Moreover, increasing the concentration of surfactant in the chemical flood causes the concentration of surfactant in the effluent to rise along with a notable increase in surfactant adsorption. We also observed that sulfate spiking has a noteworthy impact, as surfactant adsorption is decreased by an increase in sulfate concentration. Notably, injecting diluted water produced the lowest levels of surfactant adsorption. It is crucial to note that this work is the first to investigate a novel formulation of surface complexation modeling that takes into consideration the influence of interactions between polymer, surfactant, oil, brine, and rock on the adsorption properties of surfactants.
Real-Time Evaluation of the Lost Circulation Zone Based on a Changepoint Analysis of the Mechanical Specific Energy and Standpipe Pressure

There are multiple mechanisms that may drive a lost circulation event while drilling a well. Efficiently dealing with those events requires that the operations team quickly get an understanding of subsurface conditions that caused the event. Globally, some lost circulation events are cured by basic lost circulation materials (LCM) / bridging, while others fail to be cured even after days of attempts with lost circulation cement plugs (LCP) and novel materials.

The aperture of the lost circulation zone (LCZ) remains unknow in most of the cases unless open hole logs ran to identify it. The standard approach to cure the losses is to start with less aggressive materials followed by more aggressive, and the curing based on the field practices, rather being linked to the potential opening of LCZs.

The manuscript will investigate the hypothesis that the lost circulation events related to penetration of large, connected, open cavities (karsts) can be characterized, and those large open cavities can be identified in near-real time by analyzing the dynamic drilling parameters with help of Machine Learning.

There are different mechanisms that are driving the lost circulation events. Within the same formation some of lost circulation zones can be easily cured with LCM/LCP, others require more effort and time and may be uncurable. The invention proposes a workflow and an algorithm to detect from dynamic drilling parameters what is the likely mechanism at play, and whether the lost zone is curable. Large fracture and dissolution cavities will have different mechanical properties, and drilling through those features will require significantly less energy than through a competent rock formation. They are also discrete events within a geological formation, and therefore will have outlier mechanical properties within a formation.

The test was performed in over 300 wells, across different lost circulation zones (some wells had several zones). The developed algorithm was incorporated into the software in Real-time Monitoring center, allowing near real-time estimation of the aperture to decide regarding the LCM or LCP to be used. The results showed that in upper sections the multiple lost circulations zones presented with different thickness. The majority of the identified karsts are within range of 2-to-8 ft, with some going over 10 ft. In the deeper formations LCZ with the aperture of 4-to-9 ft were identified. The interesting part was related to the significant difference between MSE while drilling competent formation and the lost circulation zone, when MSE values were dropping almost to zero.

The manuscript provides the novel approach allowing to use machine learning to identify the aperture of the lost circulation based on the real time parameters. The proposed approach can be used at any drilling project worldwide.

As the outermost and largest organ of the human body, the skin is constantly exposed to solar radiation, thereby making it important to study the science of the interaction of radiation with skin called cutaneous photobiology. The electromagnetic spectrum consists of radiations of different wavelengths, but the impact of ultraviolet rays on the skin is the most important and most studied out of all. In this section, we have tried to provide a concise overview of the existing understanding of the electromagnetic spectrum, the principles of interaction of photons with skin, and its acute and chronic effects.

Ülkemizdeki Jeotermal enerji kaynaklarının %78'i Batı Anadolu'da, %9’u İç Anadolu'da, %7’si Marmara Bölgesi’nde, %5'i Doğu Anadolu'da ve %1'i diğer bölgelerde yer almaktadır. Kapodokya bölgesi son yıllarda jeotermal sektörünün potansiyelin artırılması adına pek çok yatırımın yapıldığı önemli bir saha olarak öne çıkmaktadır. Son yıllarda Hasan Dağı ve çevresinde jeotermal enerji bulmak ve işletmek amaçlı sondaj faaliyetleri sürdürülmektedir. Bunların en önemlisi 3S Kale Enerji şirketi tarafından yürütülen çalışmalarda Çiftlik-Bozköy bölgesinde, 3.814 metre derinlikte 295 °C; diğer daha derin sondajdan 3.957 metre derinlikten 341 °C kuyu dibi sıcaklık değeri elde edilmiştir. Bu iki sondaj verisinden yararlanarak sayısal modelleme çalışmaları gerçekleştirilmiştir. Simülasyon sonuçlarına göre söz konusu sıcaklık değerlerini üretebilmek için 7 km derinlikte 600-700 °C ve/veya 8 km derinlikte 900-1.000 °C sıcaklığında ısı kaynağı olarak işlev gören bir magma odasının (magma odası çatısı) üst kabukta bulunması gerekmektedir.

Hasan Dağı ve çevresinde gerçekleştirilen manyetotellurik (MT) çalışmaları sonucunda özellikle Niğde düzlüğüne doğru elde edilen profillerde 4-6 km derinlikte ve yaklaşık aynı ölçülerdeki genişlikte olası bir magma odası olduğu önerilmişti. Bu MT çalışmaları ile sondaj verileri birlikte değerlendirilerek Hasan Dağı ve çevresinde muhtemel açılacak sondaj çalışmaları için çeşitli sıcaklık belirtileri elde edilmiştir. Buna göre, Hasan Dağı güneybatısında yer alan düzlük alanlarda yürütülecek jeotermal sondaj faaliyetlerinden 3.814 metrede 120 °C; 3.000 metrede 90 °C; 2.000 metrede 74 °C; 1.000 metrede 41 °C gibi yaklaşık sıcaklık değerlerinin elde edilmesi beklenmektedir.

Published: April 2024

This study explores the conditions of social capital on the survivors of the 2022 earthquake in Cianjur, Indonesia. Cibulakan Village, Cugenang Sub-district, Cianjur was chosen for this study because it was one of the most severely affected villages by the earthquake with the highest number of fatalities in Cianjur Regency. This study discusses three forms of social capital: bonding, bridging and linking and their conditions in Cibulakan Village after the earthquake. The research used a qualitative approach and method. The data analysis process uses an interactive analysis model by Miles which divides the steps of data analysis into several parts: data collection, data condensation through open coding, axial coding and selective coding, data display and conclusion. The results showed that the earthquake triggered changes in bonding, bridging and linking social capital in both positive and negative directions. Therefore, it is necessary to pay attention to the condition and role of social capital in post-disaster communities, given that some forms of social capital lead to positive post-disaster and can be utilized after a disaster. The government and other stakeholders should consider the role of social capital in disaster-affected communities during the emergency response and recovery process to support more sustainable recovery in communities.
An advanced GIS based approach for the assessment of coastal inundation in the storm surge region (Krishna District) of Andhra Pradesh, INDIA
Authors: Malik Arshid Hussain , Uma Devi Randhi
Published: April 2024

Climate change leads coastal areas to suffer from rising sea levels, flooding, storm surges and cyclones which can cause irreparable harm to people and their assets. The mapping of these alterations to the coastline can assist in sustainable coastal development and surveillance. The current research emphasized the susceptibility of coastal inundation in the Krishna District of Andhra Pradesh, which is the State’s most vulnerable place to flooding and cyclonic storms. The Indian Meteorological Department website (mausam.imd.gov.in) was accessed to get latitudinal and longitudinal data on cyclonic storms that hit the area recently. The satellite imagery was acquired from Google Earth and USGS (earthexplorer.usgs.gov) to map the coastal settlements within 25 km radius of the coastline and to generate Digital Elevation Model (DEM) to identify the coastal inundation vulnerability up to 5.0 M contour elevation (2m, 3m, 4m and 5m). According to findings, there was a small impact of coastal inundation up to 4 meter sea level rise, so the research primarily concentrated on the assessment of coastal inundation with 5 meter sea level rise. A total of 512 settlements studied for coastal inundation encompassed an area of about 11405.4 hectares. The DEM identified that a large number of settlements in the Krishna District are on the verge of coastal inundation. About 125 settlements (24.5% settlements) with an area of approximately 2099.5 hectares are most vulnerable to coastal submergence, accounting for 18.5% of the studied area. This damage exposure assessment helps local government and policymakers to counteract extreme inundation events.

The dementia and loss of cognitive nature among humans are becoming epidemics and causing a socio-economic burden. Amnesia and cognitive behaviours are natural phenomena due to aging. The studies in young and aged mice were conducted in order to rule out the impact of aging. It has become necessary to find novel nootropic agents that are derived from natural resources. In synthetic drugs, we have a piracetam prototype nootropic. The natural products obtained from plant sources are safe and compatible with physiological conditions. Hence, we hope our scientific research may lead to novel nootropic agents with fewer side effects. Nootropic activity was assessed by elevated plus maze and T-maze activity of plant-based extracts with standard piracetam.

Every year it is estimated that 9.6 million deaths occur due to cancer disease according to the current census. Therefore, development for novel, safe and efficacious drug for treating cancer is needed. Medical plants are used for the treatment of various types of cancer since ancient times. In the present study, one attempt has been made to explore the medicinal properties of Tridax procumbens L. To prepare plant extract of Tridax procumbens using maceration method and to evaluate in vitro anti-proliferative activity on colon cancer cell line by MTT assay of the plant extract, the Tridax procumbens plant was used involving anti-proliferative potential as hydroalcoholic extract using ethanol and water (70:30v/v). The preliminary phytochemical analysis resulted in the presence of phyto-constituents in hydroalcoholic plant extract and cytotoxic potential was carried out on colon cancer cells (HT-29) using cell viability by MTT assay and plant extract showed significant anti-proliferative activity on colon cancer cells with IC50 value (74.10 μg/ml) as compared with normal epithelial cells (IEC-6) which showed the non-toxic effects. Hence it can be stated that Tridax p has excellent anti-proliferative activity and plant extract can be used in making of herbal based anticancer drugs which can be less expensive and available to all.
