Authors: Singh Kamini , Singh Anant Pratap
Published: October 2024

The National Capital Region of Delhi is ranked third as the largest built-up urban area in the world with a population density of about 14000 people per square kilometer. A complex system of public transit, paratransit and non-motorized transit system with last-mile connectivity is integral for such large areas to perform efficiently and promote sustainable transportation systems.To understand these urban processes and related space-syntax, it is crucial to understand which mode of public transport is preferred by the user and why. The user choices for a particular mode of transportation are primarily dependent on the time-cost relation of the mode. The present paper evaluates the efficiency of four modes of public and para-transit transport systems in the city of Delhi. The key modes identified are a combination of metro, bus, auto and taxi systems. The data on travel time and travel costs is collected and compared for the three selected routes. This shall be done by comparing four modes on three routes to generate 12 permutations. The selected routes have varying origin and same destination with route length of 20 kms, 12 kms and 7.1 kms respectively. The efficiency of the transportation system is evaluated on 9 parameters - velocity, Cost of vehicle & infrastructure, Travel Cost, Travel Time, Capacity, Flexibility, Aesthetics, Comfort and Maintenance. The research identifies the travel distance and settlement density to be critical elements in the user decision-making process and hence are key parameters to be considered in planning for public transportation in complex metropolitan cities.

Authors: Grigorieva M. , Kuleshova M. , Grobovoy S.
Published: October 2024

Relevance. The state of antioxydant system is of great importance for the athlets whose activities are accompanied by oxidative stress develop-ment. Thus the use of saliva as an object of biochemical analysis is very promising because of the ease of taking biomaterial. Also there are a posi-tive correlations between individual indicators of saliva and blood plasma antioxydant systems. The number of methods for assessing the antioxidant activity of saliva is known but there also remains the problem of development of simple techniques that do not require expensive reagents and equip-ment. Objective. The objective of the work is to modify and adapt the method for determining the overall antioxidant activity of saliva according to the inhi-bition rate of oxidation of Tween-80 to TBA-active products. Modification's essence lies in the use of Fenton 's reaction (Н2О2 + ions Fe2+) to initialize an oxidation. Material and methods. For the study used mixed saliva samples. In the experience I we used a method of determining the antioxidant activity pro-posed for blood plasma by Galactionova L.P. et al. (1998). According to this method Tween-80 oxidation was initiated by a mixture of Iron(II) sulfate and ascorbic acid, after which the saliva was added. In the experience II the same operations were carried out, but we added 0.1 ml of 2 % water so-lution of hydrogen peroxide. The samples were incubated in darkness at 40°С, in doing so, we used five parallel series, each with different incubation time: 1, 2, 4, 24, 48 hours. The overall antioxidant activity was determined by the degree of reduction of TBA-active products formation. Results. It was found that the addition of hydrogen peroxide to the initiating mixture makes Tween-80 oxidation and TBA-active products formation more intense than when using only Iron(II) sulfate and ascorbic acid as oxidation initiators. The maximum of TBA-active products formation is ob-served after 2 hours in contrast to 48 hours in original method. The results of determining saliva overall antioxidant activity obtained by modified meth-od also speak in favor of 2 hour samples incubation period. Conclusions. The proposed modification of the methodology for determining overall antioxidant activity by Galactionova L.P. et al. makes it possible to reduce the duration of examining and is adapted for saliva analysis.

Published: October 2024

Relevance. Pancreatin is a polyenzyme drug with lipolytic, amylolytic and proteolytic activity, and is prescribed as a replacement therapy for exocrine pancreatic insufficiency. Modern requirements for quality control of drugs involve the use of highly specific and highly sensitive methods of analysis using reference standards (RS).For RS certification it is necessary to establish the values of the certifiable characteristic. For enzyme preparations the certifiable characteristic is catalytic activity. In this connection for certification of pancreatin RS it is necessary to establish the value of its catalytic ac-tivity.The analysis of the proteolytic activity of pancreatin consists in performing a proteolysis reaction and quantifying the reaction products. The most common methods used for this purpose are those in which the quantitative content of proteolysis products is determined by measuring the optical density of the solution using tyrosine as a standard. It should be noted that the value of proteolytic activity established in this way is relative, since the measured optical density actually corresponds to a mixture of tyrosine and tryptophan. The absolute method for determining proteolytic activity is the Kjeldahl method for analyzing fragmented peptide nitrogen. Aim. Propose the method for quantitative determination of the proteolytic activity of a pancreatin RS. Material and methods. The object of the study was a pharmaceutical substance pancreatin. Quantitative determination of proteolytic activity in pancreatin substance samples was performed according to the proposed method by determining protein nitrogen by the Kjeldahl method after the en-zymatic reaction. Results. As a result of testing the samples of pancreatin substance using the proposed method of quantitative analysis of proteolytic activity, we ob-tained reliable results, indicating the high sensitivity, accuracy and reliability of this method. Conclusions. The present study proposed the method for quantitative determination of the proteolytic activity of pancreatin substance and evaluated the acceptability of its use in the quality control of a pancreatin RS.

Asserting the Right to New Cities: Farmers’ (re)claiming Space in New Clark City
Authors: Flores Jerome Christopher Samson
Published: October 2024

New cities, often designed as development strategies, cause dispossession, displacement, and disruption of everyday lives of local communities. To further explore the effects of new cities and urban development in the Global South, this study explores the realities of farmers whose homes and livelihoods are affected by the construction of New Clark City in the Philippines. Employing the concept of the right to the city by Henri Lefebvre, this study delves into the farmers' agency in reclaiming space in the city being built on their rice fields. Through qualitative research methods, including interviews and participant observation, the study elucidates the strategies employed by farmers to assert their right to New Clark City. Highlighting that (re)claiming of space by the farmers is motivated by their need to make a living and provide for their families, the study builds on the understanding of the right to the city as the right of the inhabitants to shape their environment and manage their resources. Although the right to the city heavily depends upon the collective power to reshape the process of urbanization, the article argues that it can also be asserted through individual and unorganized actions.

The growing energy demand, the increase in its price, and the increasing pollution worldwide are considered large problems that need unusual solutions. To overcome these problems, it is necessary to search for innovative solutions using renewable resources and energy management of the energy systems. Energy management means reducing the operating, maintenance, and generation costs of the system and enhancing system performance with methods such as power loss reduction and stability enhancement and alleviating the harmful emissions to the environment. Thus, the energy management of a micro-grid has become one of the most vital aspects of the power or energy system all over the world.The objective of this paper is to optimize a multiobjective problem of a renewable energy resources (RER) based multimicrogid (MMG) system considering the output variation of the photovoltaic (PV) and wind Turbine (WT) as renewable energy resources and variation of the load demand and electricity prices. In this paper three microgrids (MGs) are connected with IEEE 33-bus distribution system each MG consists of a PV and WT. A three objective functions are modeled for this system to optimize the total annual cost, the voltage deviation and the voltage stability index (cost –performance multiobjective function). The optimization problem is solved with particle swarm optimization (PSO) technique for the system with and without RER.A comparison is carried out with two other optimization techniques, mountain gazelle optimization (MGO) and gorilla troop optimization (GTO). The results of the simulation show that the system cost is considerably reduced and the performance optimized.

Ultra-high molecular weight polyethylene, or UHMWPE, is a thermoplastic semicrystalline polymer with outstanding wear resistance, low friction coefficient, and mechanical qualities. It also can exhibits powerful resistance to corrosive substances. Even Ultra-high molecular weight polyethylene (UHMWPE) has unique characteristics, but it features an extremely low melt flow rate (MFR) of near zero, which renders it unsuitable for processing using traditional polymer processes. Thus, PP is one of the most potential plasticizers for increasing the extrudability of UHMWPE-based composites. PP, commonly known as Polypropylene, is a thermoplastic polymer that is widely used in many industry sector. It is made from the monomer propylene using chain-growth polymerization. However, there is a problem where the chemical incompatibility of the PP-UHMWPEcomposites makes the composite is difficult to manufacture. As a result, the intent of this research is to examine the characteristics of both materials in order to acquire a better knowledge of the requirements and to present a deeper insight into these two materials in order to increase the extrudability of PP-UHMWPEcomposite for Fused Filament Fabrication (FFF). The characterization procedure comprises the morphological and flow properties, thermal behavior and stability, and crystallinity of UHMWPE and PP in powder and granular form, respectively. The research illustrates the feature for both polymer behavior that is influenced by particle shape. This paper's findings were utilized to manufacture the extrudability of PP-UHMWPEcomposites using FFF as a bone repair implant.

The utilisation of by-products in paver block production has gained significant attention due to its potential in environmental condition. This research investigates the effect of incorporating rubber tyre waste and bamboo fibre into the fabrication of paver block on compressive strength, water absorption, density and ultrasonic pulse velocity tests. This research comprises two batches of paver blocks fabrications following a 1:2:3 ratio(cement: fine aggregate: coarse aggregate). Batch 1 involves the fabrication of paver blocks by incorporating varying percentages of rubber tyre waste (0, 10, 20, 30, 40 and 50%), which replace a portion of the sand (referred to as rubber paver block). In Batch 2, various dosages of bamboo fibre, used as a reinforcement material were added to the paver block containing 40% rubber tyre waste, which are referred to as rubber-bamboo fibre paver blocks. Nevertheless, the compressive strength of the rubber-bamboo fibre paver blocks was further examined under two simulated environmental conditions: (1) air and dry cycle, and (2) wet and dry conditions. These conditions aim to assess the block’s resistance to temperature fluctuations, moisture effects, and theiroverall durability. The strength of the paver blocks decreases with the additional inclusion of rubber tyre waste. While the utilisation of 0.3% bamboo fibre has shown improvement in its strength performance compared to 0.2% and 0.4%. It suitable to used for non-loading structural applications that require strength below 25 kPa. This study was able to promote sustainable and green construction materials for paving applications through the efficient recycling of waste materials. It aligns with Sustainable Development Goals (SDG) 9 (Industry, Innovation, and Infrastructure) and 11 (Sustainable Cities and Communities).

Published: October 2024

Non-destructive testing on offshore rigs involves multiple sections. The topside platform structure, which consists of the main deck, cellar, and sub-cellar deck, is one of the most important sections. The purpose of this research is to use appropriate nondestructive testing (NDT) methods to assess the internal and surface defects as well as identify the material properties of the selected structure at the topside platform structure. Various NDT technologies can be utilized to detect faults on the topside of the offshore platform. The NDT techniques used in this study are ultrasonic, magnetic particle, and dye penetrant testing. To describe the material in the samples, a different method known as positive identification material is employed. Four tasks are involved in this process: identifying the material properties of each sample, identifying surface and interior faults, and comparing the two types of defects. The results of the analysis revealed that a 316L stainless steel specimen contained as much as 19.2% chromium, 11.8% nickel, and 3.0% molybdenum. Magnetic particle inspection was recommended for surface and subsurface inspection. In contrast, the ultrasonic testing examination yielded the best outcome for the topside offshore platform's interior problem.

The oil and gas industry is inherently known for its riskiness, involving numerous activities and a variety of chemicals naturally present in the plant environment. Simultaneously, it has been observed that certain activities classified as critical, such as crane lifting, hydrostatics, excavations, hot work, and confined spaces, pose significant risks. Previous studies have shown that between the years 2009 and 2019, there were many reported incidents, with a total of 46 verified cases of deaths occurring in confined spaces in Malaysia. These incidents underscore deficiencies in the current system that need addressing. Therefore, this study aims to collect data on confined space incidents and issues in the oil and gas industry to propose a new intervention plan for employers and workers. The current working practices in confined spaces were analysed for this purpose. The data were gathered through survey questionnaires distributed to workers employed in confined spaces. The obtained data were analysedusing the SPSS system to conduct reliability tests, ANOVA, and Pearson Correlation. The results of the ANOVA analysis indicated that there was no statistically significant difference at the p < 0.05 level for n = 50 concerning Age Categories, Position Categories, Years of Service, and Education Background in their perceptions of confined space work practices at Gas Processing Kertih (GPK). Additionally, Pearson Correlation analysis revealed a strong statistical correlation (r > 0.5, n = 50, p < 0.05) between Incidents in the Workplace and Health or Disease Problems. Based on the findings, suitable intervention plans have been proposed, such as transparency on Incident Reports by Management, quality training for confined space workers, and implementation of an efficient toolbox meeting to assist management in addressing the challenges associated with confined space working practices at GPK.

Building construction refers to the methods and businesses associated with assembling and erecting structures, particularly those designed for residential purposes. The need for a controlled environment to mitigate the effects of climate change was initially purely functional. A construction site presents a wide range of ever-evolving threats, with risks that are often unique to the construction business. Therefore, ensuring that workers are well-trained and aware of these risks is essential for safeguarding themselves and their coworkers from potential harm or even fatalities. This research aims to explore the root causes and consequences of falling object incidents on individuals, assets, and reputation within the construction industry. Thoroughly analyzing the root causes and consequences of incidents informs the development of a targeted intervention plan. This plan aims to reduce severity and address specific issues, such as inadequate safety measures or equipment failures, with the overarching goal of significantly decreasing falling object incidents. This study employs a survey questionnaire as its methodological tool. The procedure includes conducting literature reviews and incorporating sample survey questionnaires from previous researchers. The methodology used to analyze the statistical data was SPSS software via Reliability Tests, One-way ANOVA Tests, and Correlation and Interferential Analysis. The results revealed a strong statistical correlation (r > 0.5, n = 50, p < 0.05) between organizational/departmental roles and responsibilities, the behavioral behavior of construction workers, incidents at work, health/disease problems, and the consequences of the incident. Therefore, to mitigate all the potential consequences, some intervention plans are being proposed, such as the implementation of Toolbox Meeting (TBM) and Toolbox Talk (TBT), a Toolbox Training Program, and the monitoring of physiological conditions for construction workers to maintain the well-being of the workforce and ensure a safe working environment.

Agarwood leaves have long been used as herbal medicine due to their diverse pharmacological qualities, oneof which being laxative abilities to relieve constipation. Constipation is interpreted as a gastrointestinal ailment in which the stools are dry and firm with difficulty and infrequentevacuation. People generally suffer in silence and choose to take over-the-counter medications rather than addressing the problem. The main issue here is that currently available laxatives induce undesirable sideeffects such as cramps, diarrhea, nausea, and others. Previously conducted research discovered that Aquilariaspecies agarwood leaf extract has laxative qualities and has no adverse side effects on animal testing. Genkwanin 5-O-β primeveroside and mangiferin are shown as the major bioactive compounds in agarwood leaves extract that induce laxative effects. This review focuses on the laxative characteristics of agarwood leaves, bioactive compounds, and previous studies on in vivotesting.

Anak usia dini membutuhkan stimulasi yang tepat dalam pengembangan kemampauan baik dari aspek kognitif, afektif, dan psikomotor. Oleh karena itu dibutuhkan layanan pendidikan dan kapasitas pendidik yang tepat dan mumpuni untuk mendampingi anak mengembangkan potensinya. Undang-undang No. 14 Tahun 2005, tentang guru dan dosen dijelaskan bahwa kompetensi yang harus dimiliki oleh seorang guru adalah kompetensi pedagogik, kompetensi kepribadian, kompetensi sosial dan kompetensi professional. Kompetensi kepribadian adalah kompetensi awal untuk dapat mengembangkan kompetensi yang lain dan untuk membentuk karakter siswa terutama anak usia dini yang membutuhkan role model yang baik. Banyak pengkajian tentang karakteristik guru dan pengembangannya, tulisan ini lebih fokus pada konsep dari pengembangan itu sendiri dilihat dari perspektif teori kepribadian Hippocrates Galenus dan kepribadian perspektif islam. Penulisan menggunakan pendekatan penelitian literatur. Hasil dari penelitian ini adalah teori kepribadian Hippocrates Galenus adalah potensi psikis dan teori kepribadian perspektif islam adalah potensi ruhaniah yang setiap individu memilki kedua potensi ini. Semua kekuatan karakter di tipologi Hippocrates Galenus adalah karakter muthmainah di teori kepribadian islam, sebaliknya kelemahan karakter di tipologi Hippocrates Galenus adalah karakter ammarah di tipologi kepribadian islam. Oleh karena dalam pengembangan kompetensi kepribadian guru terutama guru PAUD perlu memahami kedua teori kepribadian tersebut agar dapat maksimal dalam mengembangkan kompetensi kepribadiannya.

Graphene oxide for high performance nonlinear optics in integrated
Authors: Moss David
Published: October 2024

We report enhanced nonlinear optics in integrated nanophotonic chips through the use of integrated with 2D graphene oxide (GO) films. We investigate nanophotonic platforms including silicon, silicon nitride and high index doped silica. Due to the high Kerr nonlinearity of GO films and low nonlinear absorption we observe significant enhancement of third-order nonlinear processes. In particular, in silicon we observe an increase in both the Kerr nonlinearity and nonlinear figure of merit of up to 20 times. These results show the strong capability of GO films for improving the nonlinear optical performance of integrated photonic devices.

Authors: San Segundo Eugenia , Delgado Jonathan
Published: October 2024

En este estudio preliminar, se eligió a dos parejas de gemelos varones idénticos (esto es, monocigóticos) de un corpus más amplio. Se establecieron dos criterios para seleccionarlos: (i) edad similar y (ii) distancia euclidiana similar entre cada hablante y su gemelo. Se analizaron acústicamente 12 muestras de voz, de unos 3-5 segundos de duración cada una, extraídas de conversaciones espontáneas semidirigidas. Las muestras analizadas comprenden dos muestras de voz natural por cada gemelo y otra muestra consistente en una voz clonada artificialmente con una herramienta comercial de clonación de voz mediante inteligencia artificial. Se analizaron con PRAAT un total de 21 parámetros acústicos relacionados con la cualidad de voz. Los resultados preliminares muestran diferencias en el rendimiento de los parámetros acústicos, así como diferencias entre las parejas de gemelos.
