Published: August 2021

Este artigo analisa o Programa de Educação Integral, implantado no nível médio da rede estadual de ensino do Estado da Paraíba, do ponto de vista da dinâmica da produção e reprodução das desigualdades. O objetivo será investigar, primeiramente, como as barreiras socialmente impostas pelas desigualdades sociais refletem no acesso e permanência dos estudantes do ensino médio das escolas do referido programa. Partindo de uma abordagem metodológica qualitativa e quantitativa e de um estudo bibliográfico fundamentado em autores clássicos e contemporâneos da Sociologia da Educação, foram levantadas algumas variáveis socioeconômicas e realizadas entrevistas que permitem a análise de alguns fatores que contribuem para investigar também as possíveis desigualdades geradas no bojo da própria política. Nesse sentido, os resultados preliminares apresentados indicam que o referido programa não apenas reproduz as desigualdades sociais impostas como barreiras que dificultam o acesso e permanência dos jovens, como também recria ou exponencia essas desigualdades.
Coaching educacional
Authors: De Aguiar Taylor
Published: August 2021

Este trabalho aborda as variações da prática de coaching nas trajetórias de três professoras que atuam como coaches educacionais. Partindo de uma abordagem antropológica, enfatizamos relatos e percepções das três docentes sobre suas carreiras profissionais e destacamos elementos que compõem diferencialmente as suas práticas pedagógicas em torno do coaching. Nos três casos abordados, a aplicação do coaching à educação apresenta variações que mobilizam sentidos específicos em torno da ideia de “autonomia”. Argumentamos que, pelo entremeio dessas variações, há uma pedagogia do self-making a operar como matriz comum, informando ao coaching educacional uma perspectiva em que o sujeito educando é tomado como um empreendedor de si mesmo. Concluímos que a ênfase posta sobre a ideia de “autonomia” guarda relação com uma concepção de capital educacional extensiva à noção de capital humano.

Published: August 2021

O artigo analisa a produção de diferenças em uma Escola Pública Estadual de Ensino Fundamental de Belém (PA) a partir de um fazer racializado para a educação escolar. Nesse processo, desenvolvido com o aporte de uma pesquisa de campo com estudantes do 5º ano, cruzamos narrativas históricas sobre relações raciais e miscigenação para a compreensão de como o racismo operava no cotidiano escolar das/os interlocutoras/es. Evidenciamos a reprodução de linguagens raciais de caráter naturalista, difuso e rarefeito utilizadas por professoras/es e gestoras/es escolares que, em sua maioria, manejavam percepções compactas e universalizantes acerca do ensino, acentuando desigualdades por meio da instrumentalização de práticas de inclusão e respeito.

Type 2 diabetes is one of the main factors of the cardiovascular risk, which leads to a disproportionateincrease in cardiovascular events in women and men. All causes of increased cardiovascular risk in women withtype 2 diabetes mellitus are not established, one of the most likely causes of cardiac activity is considered to begender features of biogenesis and activity of myocardial mitochondria. A comparative analysis of changes in thefunctional state of the heart mitochondria in males and females rats with experimental type 2 diabetes mellituswas conducted. It was established that the activity of succinate dehydrogenase, the part of complex II of theelectron transport chain, reduced more significantly in diabetic males compared with diabetic females. Type 2diabetes mellitus also caused a greater decrease in the activity of the energy metabolism enzyme — aconitase,in heart mitochondria of male compared to female. One of the leading mechanisms of cardiomyocytes’ apoptoticor necrotic death in conditions of mitochondrial dysfunction, in particular induced by diabetes, is the activationof a nonspecific mitochondrial pore opening (mPTP, mitochondrial permeability transition pore). It was founda more pronounced activation of mPTP and more significant decrease in thioredoxin reductase activity inmales with type 2 diabetes mellitus compared with diabetic females. The obtained data may indicate a greatersensitivity of male cardiomyocytes to the damaging effects of proapoptotic factors

Published: August 2021

Curcuminoids can be successfully extracted from Curcuma zedoaria using natural deep eutectic solvents (NADES) as extraction solvents. However, a mixture of extracted curcuminoids, NADES, and impurities from C. zedoaria was obtained as a slurry at the end of the extraction process. Therefore, further separation and purification were required to obtain the extracted compound in high purity. Herein, two purification methods based on classical column chromatography (CCC) and solid-phase extraction (SPE), were evaluated for the purification of curcuminoids from NADES matrices after extraction. Choline chloride–malic acid–water (CCMA–H2O) and choline chloride–citric acid–water (CCCA–H2O) in the molar ratio of 1:1:18 were selected as NADES matrices due to their high solubility and stabilization capability for curcuminoids. Ethanol-conditioned silica gel (60–200 µm) was applied as the bed resin for CCC, and a C18 cartridge was used for SPE. Acetonitrile/0.1% acetic acid, water/0.1% acetic acid, and iso-propanol/0.1% acetic acid were used as mobile phases for CCC. For SPE, methanol/0.05% acetic acid and water/0.05% acetic acid were applied in the conditioning step, water/0.05% acetic acid in the washing step, and methanol/acetonitrile (1:1) in the eluting step. The SPE method produced higher recovery of curcuminoids from the CCCA–H2O and CCMA–H2O matrices (75.27% and 73.40%, respectively) compared to CCC (51.9% and 61.0%, respectively). After removing the NADES constituents from the crude extract of curcuminoids, recrystallization was attempted.

Published: August 2021

Diabetes mellitus is a chronic disease in which the body is unable to metabolize carbohydrates, fats, and proteins. In this study, eugenol was polymerized and then contacted with glucose and crosslinked using polyethylene glycol diglycidyl ether (PEGDE). The resulted PE-Glucose-PEGDE was eluted using ethanol to form MIP-Glucose. It was then characterized by FTIR, SEM, electrodes using the Eutech 510 potentiostat and UV-Vis spectrophotometer. The result of polyeugenol synthesis is a reddish-brown powder with a yield of 99.90% and a molecular weight of 6318.033 g/mol. UV-Vis spectrophotometer analysis showed that the contacted glucose was 2152.505 ppm. SEM results showed differences in the surface morphology of the material, indicating the formation of cavities in MIP and ESM, while no cavities are found in NIP and ESN. The electrode optimization resulted in the best composition ratio of MIP 1 mol: paraffin: graphite, respectively of 20:35:45. The resulting electrode has a Nernst factor of 20.24 mV/decade with a measurement range of 10–5–10–1 M, a limit of detection value of 8.363 × 10–5 M, and the value of the selectivity coefficient (Kij) of the electrodes in a (10–5–10–1) M fructose solution was 0.3733; 0.23048; 0.17864; 0.12359; 0.1073.

Published: August 2021

Crude oil is an indispensable energy feedstock for daily activities, although some amounts of metallic porphyrins components with undesired characteristics have been identified. These constituents are assumed to originate from the geochemical process of chlorophyll and heme derivatives. In addition, their chemical structures have been thoroughly characterized using spectroscopy techniques, while several analytical methods were adopted in the detection and concentration quantification in the crude oils. The metallic porphyrins have several demerits, including the deactivation of used catalysts, contamination of the treated petrochemical products, and corrosion of the industrial equipment. Also, the removal process is considered challenging due to the strong interaction with the asphaltene fraction of crude oil. This review article, therefore, provides brief information on the origin, physicochemical properties, and possible removal technology of metallic porphyrins from crude oil samples. Besides, a better understanding of chemistry contributes a useful insight towards the development and establishment of better futuristic processing technology.

Published: August 2021

The major cause of early failure in the infrastructures of the palm oil industry in Aceh, Indonesia has been discovered to be the corrosion caused by air pollution from exhaust fumes of the factory plants. Therefore, this research was conducted to analyze the effect of the atmospheric corrosion of the structural steel used in the palm oil mill industry. The five types of structural steel used as samples include strip, l-shape, round bar, plate, and SAPH 610 low carbon steel with a carbon content of 0.18%. These specimens were cleansed from dirt, scaled, and rubbed with sandpaper to achieve a grid of 600, later washed with fresh water and rinsed with alcohol, and subsequently exposed to the environment in PT ASN and PT AKTS palm oil mills for 12 months. Moreover, they were placed on a measuring tray for exposure and the corrosion rate was recorded once a month using the mass loss method in line with the ASTM G50. The results showed the steel construction with a round bar shape was more resistant to atmospheric corrosion and the remaining samples were also observed to be safe and relatively resistant based on their classification as being outstanding (< 1 mpy).

Authors: Nastiti Christofori Maria Ratna Rini , Riswanto Florentinus Dika Octa
Published: August 2021

Resveratrol (RSV), a natural lipophilic phytoalexin, was reported as an antioxidant and anti-inflammatory agent, which has the potential to cure diabetic wounds. However, several studies suggested the limitation of RSV, such as poor aqueous solubility, poor stability, and poor oral bioavailability. To overcome the issues, RSV was formulated as a topical nanoemulsion. It is important to ensure the quality of the dosage form by evaluating RSV load in the nanoformulation and optimizing the formula. A reversed-phase HPLC method was developed and validated prior to the load determination of RSV in the nanoemulsion formulation. The composition of triacetin-eugenol, Kolliphor® RH 40, and Transcutol® was further optimized by employing a Box-Behnken Design (BBD) to achieve the optimum composition with expected viscosity and RSV load. The HPLC method for determining RSV load was successfully validated for parameters of selectivity with the resolution of 8.487, linearity and range (r = 0.9979), precision (0.12% of RSD), accuracy (109–110% of recovery), the limit of detection (0.574 µg/mL), and limit of quantitation (1.740 µg/mL). The result of formula optimization was promising, showing the optimum composition of triacetin-eugenol, Kolliphor® RH 40, and Transcutol® at 4.44 g, 30.97 g, and 11.39 g, respectively.

Polyvinylidene fluoride (PVDF) membrane and its derivative have been investigated the permeation ability for creatinine and urea. The membrane was made by an inversion precipitation system in N,N-dimethyl acetamide (DMAc) and water as non-solvents. In this study, the modification of PVDF membrane permeability with PEG additives, CBT variations, and sulfonation was successfully carried out. The membrane solidification process was carried out on three variations of the coagulation bath temperature (CBT): 30, 45, and 60 °C. Eight types of membranes were characterized by using FT-IR and TGA/DSC, followed by the analysis of their porosity, hydrophilicity, water uptake, swelling degree, tensile strength, and permeability of creatinine and urea. The FT-IR spectra indicate that PVDF modification has been successfully carried out. The porosity, hydrophilicity, water uptake, and swelling degree values increase with the modification of functional groups. Furthermore, improvements in creatinine and urea permeability and clearances are achieved by increasing CBT and sulfonation in the PVDF/PEG membrane. The presence of sulfonate groups improves the membrane permeability through the interaction of intermolecular hydrogen with water and dialysate compounds. The existence of PEG as a porogen enhanced membrane porosity. Creatinine and urea clearance values increase from 0.29–0.58 and 6.38–20.63 mg/dL, respectively.

Authors: Baari Muhamad Jalil , Bundjali Bunbun , Wahyuningrum Deana
Published: August 2021

The presence of salts and dissolved gas like CO2 that is carried with natural gas and crude oil along the pipeline is the main reason for corrosion and scale formation. These problems are usually resolved separately by corrosion inhibitors and scale inhibitors or acidification. Meanwhile, utilizing a compound to resolve both corrosion and scale formation has an advantage in the economic side and working time. N,O-carboxymethyl chitosan or N,O-CMCs is one of the chitosan's derivates. It is water-soluble and has different functional groups. Those properties support its capability as a complexing agent on corrosion and scale inhibitors. Synthesis of N,O-CMCs was carried out by chemical reactions between chitosan and chloroacetic acid under alkaline circumstances. N,O-CMCs product was characterized using FT-IR and 1H-NMR spectroscopy. The inhibition efficiency was analyzed by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. The measurements showed that the highest efficiency of corrosion inhibition reached 63.54% when the concentration and temperature were 30 ppm and 35 °C, respectively. N,O-CMCs was classified as a mixed-type inhibitor. The adsorption mechanism of the inhibitor followed Langmuir adsorption isotherm. The static scale inhibition test informed that the optimum inhibition efficiency of N,O-CMCs reached 60.00%.

Published: August 2021

This study investigates nutritional value, amino acid profile, and total anthocyanin in pigmented rice as an antioxidant and anti-diabetic agent. Six rice varieties were extracted using 0.1% HCl in methanol, namely four red rice, one black rice, and one white rice. Rice extract was used for proximate analysis and amino acid profiling. Total anthocyanin was measured and identified by ultraviolet-visible (UV-Vis) spectrophotometer and thin-layer chromatography (TLC). The antioxidant activity was determined using Ferric-reducing antioxidant power (FRAP) assay, and the α-amylase enzyme-inhibited by anthocyanin extract of red rice as anti-diabetic was measured. The study result showed that the proximate level (carbohydrate, protein, lipid, water, and ash) in pigmented rice was different. Cempo merah red rice is a source of amino acids, both essential and non-essential amino acids that act as good nutrition. The highest total anthocyanin level between red rice varieties of 10.87 mg/g was found in Aek sibundong red rice. High biological function activities as an antioxidant were indicated by Aek sibundong red rice with an IC50 value of 6.65 µg/mL. Aek sibundong red rice shows the lowest IC50 value of 144.46 µg/mL in anti-diabetic activity. Thus, Aek sibundong red rice may have the potential as α-amylase inhibitor for diabetes prevention.
Ground State Energies of Helium-Like Ions Using a Simple Parameter-Free Matrix Method
Authors: Pingak Redi Kristian , Ahab Atika , Deta Utama Alan
Published: August 2021

This study aims to use hydrogenic orbitals within an analytic and numeric parameter-free truncated-matrix method to solve the projected Schrödinger equation of some Helium-like ions (3 ≤ Z ≤ 10). We also derived a new analytical expression of the ion ground state energies, which was simple and accurate and improved the accuracy of the analytic calculation, numerically using Mathematica. The standard matrix method was applied, where the wave function of the ions was expanded in a finite number of eigenvectors comprising hydrogenic orbitals. The Hamiltonian of the systems was calculated using the wave function and diagonalized to obtain their ground state energies. The results showed that a simple analytic expression of the ground state energies of He-like ions was successfully derived. Although the analytic expression was derived without involving any variational parameter, it was reasonably accurate with a 0.12% error for Ne8+ ion. From this method, the accuracy of the analytic energies was also numerically improved to 0.10% error for Ne8+ ion. The results clearly showed that the energies obtained using this method were more accurate than the hydrogenic perturbation theory and the uncertainty principle-variational approach. In addition, for Z > 4, our results were more accurate than those from the geometrical model.
Transfer Learning for Spam Text Classification
Authors: Bongale Pratiksha
Published: August 2021

Today’s world is mostly data-driven. To deal with the humongous amount of data, Machine Learning and Data Mining strategies are put into usage. Traditional ML approaches presume that the model is tested on a dataset extracted from the same domain from where the training data has been taken from. Nevertheless, some real-world situations require machines to provide good results with very little domain-specific training data. This creates room for the development of machines that are capable of predicting accurately by being trained on easily found data. Transfer Learning is the key to it. It is the scientific art of applying the knowledge gained while learning a task to another task that is similar to the previous one in some or another way. This article focuses on building a model that is capable of differentiating text data into binary classes; one roofing the text data that is spam and the other not containing spam using BERT’s pre-trained model (bert-base-uncased). This pre-trained model has been trained on Wikipedia and Book Corpus data and the goal of this paper is to highlight the pre-trained model’s capabilities to transfer the knowledge that it has learned from its training (Wiki and Book Corpus) to classifying spam texts from the rest.

Authors: Sharma Vaibhav
Published: August 2021

The objective of this paper is to apply the concept of fan wing to agricultural aircrafts which are conventionally fixed wings aircrafts or multi-rotor drones. Fan wing is capable of producing good amount of lift at a sufficiently low speed without stalling, thus is apt for agricultural processes of irrigation, spraying pesticides, etc. Fan wing has a special ability that it doesn’t stalls (for the practical range of AOA), making this spraying method reliable. A fanwing aircraft is modelled using CATIA V5 and the flow visualizations for the same are performed on the ANSYS. This aircraft is then compared with three different existing agricultural aircrafts on different parameters, namely payload capacity, work efficiency and ease of operation. The comparison shows that such fanwing vehicle is a good substitute over the conventional fixed wings and multi-rotor drones.

To bring gas to those end users within the boundaries of a significant city, it's necessary to create city gas distribution pipeline networks, these networks have already been founded within the cities of Delhi, Mumbai, Vadodara, Firozabad, Kanpur and plenty of more such networks are planned within the near future. Given the infrastructure and layout available in typical Indian cities, it becomes difficult to make such gas distribution networks without separate corridors for competing utilities. Reckoning on pressures, flow rates and economic criteria, these networks may be constructed with steel pipes, polyethylene (PE) pipes or a hybrid PE-steel pipe system. In contrast to borehole pipelines, which stretch for miles directly through open fields, the CGD network is more complex. These are located in densely populated areas, and an oversized number of network branches meet the wants of users in several locations in an exceedingly city. Although they're much smaller long and size than background pipelines, a city's network is far more dispersed and diverse. The rise within the number of branches means over the amount of sleeves, bends, reducers, fittings, etc. within the network, with the exception of the quantity of delivery points for the availability of fossil fuel. Due to the assorted activities of third parties other city agencies, the chance of injury and accidents is even on top of the substantial pipelines. of these factors require better security systems integrated into the network and therefore the need for special preparation to manage any emergency situation.

Abstract: The increasing mobility of electric vehicles has inspired vehicle growth to power grid technology. Such as vehicle to grid technology allows to transfer the power from the electric vehicle battery to the power grid. This enable speak load shaving, load leveling, voltage regulation, and improved stability of the power system. To develop the vehicle to grid technology requires a specialized EV battery charger, which permits the bi-directional energy transfer between the power grid and the electric vehicle battery. There is a specific control strategy used for a bi-directional battery charger. The proposed control strategy is used for charge and discharge battery of EV. The charger strategy has two parts: 1) Bidirectional AC-DC Converter in two-way Communication System. 2) Bidirectional DC-DC Buck-Boost Converter. There are two modes of operation for a bidirectional ac-dc converter: for G2V, rectifying mode is used, and for V2G, inverter mode is used. The suggested charge strategy not only allows for two-directional power flow but also provides power quality management of the power grid. Fuzzy logic controller (FLC) transforms linguistic control topology evaluations knowledge into an automated control topology using FLC. The FLC is more stable, has less overshoot, and responds quickly. The operation of a standard PI controller and a FLC was compared in this study using MATLAB and Simulink, and different time domain characteristics were compared as toshow that the FLC had a smaller overshoot and a faster response than the PI controller. Keywords: Bi-directional AC-DC converter, bi-directional DC-DC Buck-Boost converter, electric vehicles (EVs), on-board battery charger (OBC), grid to vehicle (G2V), vehicle to grid (V2G).
Weldment to Casting Conversion Using Topology Optimization
Authors: Kulkarni Prasad
Published: August 2021

Abstract: The automobile and off highway industries grapple with dilemma of making a required component out of a weldment by welding different plates together or making a single component using a casting manufacturing process. The decision is always based on many parameters viz. volume of manufactured components, tooling cost involved, dimensional stability required, cost of welding, fatigue strength required etc. As the volume of the manufactured components increases, the cost of casting and its tool goes down and hence it makes sense to convert the weldment into a casting. A traditional method to do this is to convert the weldment into a casting based on functionalities and experience. In this paper, a topology optimization based approach is used to understand and decide the most optimal usage of the material based on the different constraints. In this paper, considerations of weldment to casting conversion, usage of topology optimization to arrive at final design and strength and fatigue life calculation are discussed. Keywords: Weldment, Topology Optimization, casting, Design for Manufacturability

Abstract: A dual-band, Square-shaped Microstrip Patch Antenna (SMPA) with two opposite corner cuts is proposed. The presented design is suitable for 4G/LTE and Wi-Fi applications as it resonates at 2.13GHz and 2.41GHz frequencies. The FR4 substrate with co-axial feed is used for fabrication and is simulated using CST software. The simulation result provides enhanced antenna specification of return loss (-42.64&-20.13) dB, bandwidth (62.7&89) MHz and percentage bandwidth (2.94&3.69) % than the conventional antenna prototype. Furthermore, a comparative study of simulated and experimental findings is analyzed in this manuscript. Keywords: Dual-band, return Loss, Bandwidth, Percentage Bandwidth, 4G/LTE, Wi-Fi
Geo Tracking of Waste
Authors: Pulikal, Sahil
Published: August 2021

Abstract: Littering of waste causes a lot of negative impact on the environment as well as it affects the economy of the nation. Because of unavailability of a proper waste tracking and detection system, littered waste remains uncleaned. The traditional way of waste management includes regular waste collected by the groups assigned such as municipal corporation trucks. To overcome this problem, we develop a system where the admin can capture images using a mobile camera and using artificial intelligence, it processes those images and identifies the type of waste present in the image. It also maps the waste locations along with its images on a map. At the end, the admin notifies the nearest garbage collector to clean the waste. The system uses the concepts of image processing, deep learning and object detection. Keywords: Object Detection, Image Processing, Coordinates, Deep Learning, Mapping
Tool Evaluation & Design Analysis for Parking Pawl Mechanism

Abstract: Automatic Transmissions in vehicles are becoming the norm today and with the need to reduce fuel consumption, electric vehicles are increasing in number too. As the vehicles get smarter, transmissions have also felt the need to adapt so as to cope with the demands of the 21st century. Apart from providing the user with different driving modes, vehicles with an Automatic Transmission and electric vehicles have a device called a Park Lock. Park Lock Mechanisms are devices that are fitted to vehicles with an automatic transmission or electric vehicles which can secure the vehicle mechanically in addition to the parking brakes to prevent an unintended movement of the vehicle when the vehicle is brought to a stop. This system can face various kinds of loads coming from the transmission or from the wheel side. So, it is necessary to design a system which can withstand against it. Today, when a park lock mechanism is designed, it is designed in a way that it not only fits one vehicle variant but many variants (these variants can include either front wheel drive, rear wheel drive, vehicles with varying final gear to park lock gear ratios etc). Therefore, one Park Lock Mechanism needs to satisfy various conditions and requirements. Carrying out calculations with different notations for each variant becomes a cumbersome procedure, therefore it is prudent to have one common platform which can do the calculation in the early phases of design. In this paper, a closed form calculationsbased Excel VBA tool can able to estimate the loads coming on to the Park lock mechanism by doing some background calculation is presented followed by the simulation performed using Multi Body Dynamics software (‘ADAMS’). Results from MBD tool and a 1D tool are corelated to the test data to gain some confidence on the tool which created in Excel VBA. Keywords: Park Lock Mechanism, ADAMS, 1D Tool, Excel VBA, Drop in Speed, Torque Build up.
