Self-Colorimetric Determination of Bio-Ethanol Using Permanganate in Fermentation Samples
Authors: Abulela Mohamed Abdelazim
Published: June 2021

Without the aid of chromatographic techniques, quantification of bio-ethanol in fermentation-broth distillate becomes inconvenient. Potassium permanganate is preferable over potassium dichromate because of the latter well-known toxic properties, it is common used in ethyl alcohol determination either by visible determination of Cr(III) green optical density, a consumed Cr(VI) determination in strong acid medium by measuring band absorbance decrease at 267 nm or the unreacted Cr(VI) determination iodometrically after alcohol oxidation. Nevertheless, these titre methods arise difficulties experience analysts from multiple solutions preparation, standardization that should be carried out every day and to successful end point detection in the presence of Cr(III) green color which leads to a significant ethanol quantification error. Noteworthy permanganate-iodometrydrawbacks as same as titre dichromate difficult practical procedures and multiple reagents employed.In this laboratory a self colorimetric method was developed in neutral medium as alcohol-specific oxidizing agent precludes both of its undesirable high oxidizing properties and difficult titrimetric methodologies for bio-ethanol quantification. It is based on unreacted permanganate optical density difference between a non ethanol-containing sample as a blank and ethanol-containing sample is directly proportional to the consumed permanganate amount in ethanol red-ox reaction and consequently directly proportional to ethanol content. This optical density difference versus ethanol concentration 1-6% v/v obeys Beer-Lampert law provides limit of detection, limit of quantification and correlation coefficient equal 0.17%, 0.56% and 0.999 respectively.

Published: June 2021

It has been recognized that the understanding of the photo physic of the dyes used in solar cells in an important step in improving their efficiency. Certainly using ionic liquid as an electrolyte is a good solution as it stabilizes the excited state of the dye, however, because of the high viscosity, the diffusion of the components of the solar cell (dye, electrolyte, the chosen redox couple) is very low and has consequences on the other processes (Forward and backward processes). One of the ideas, is to modulate the viscosity of the ionic liquid by mixing the ionic liquid with a solvent. The goal then of this work is to quantify the mixture composition dependence of the excited state relaxation times. Other studies should be carried out to quantify the mixture dependence on the time characteristics of other processes (charge injection, collection etc.) to optimize the working optimal conditions of the solar cell. Following this goal, the present study is devoted to characterize the relaxation time of in the whole mixture composition of BmimBF4 and acetonitrile and in the neat components. For the first time, the decay relaxation times of the first excited electronic state of D149 dye, as obtained by transient absorption spectroscopy (TAS). These relaxation times are monitored by a gradual change of the local structure around a dye, from the one dominated by the interionic interactions, high viscosity and low polarity (as quantified by the static dielectric constant) in BmimBF4 to the one that is dominated by dipole-dipole interactions, low viscosity and high polarity in acetonitrile.

Published: June 2021

Here, we report the phospha-bora-Wittig reaction for the direct preparation of phosphaalkenes from aldehydes, ketones, esters, or amides. The transient phosphaborene Mes*P=B-NR2 reacts with carbonyl compounds to form 1,2,3-phosphaboraoxetanes, analogues of oxaphosphetane intermediates in the classical Wittig reaction. 1,2,3-phosphaboraoxetanes undergo thermal or Lewis acid/base-promoted cycloreversion, yielding phosphaalkenes. Experimental and density functional theory studies reveal far-reaching similarities between classical and phospha-bora-Wittig reactions.
Domino Suzuki-Miyaura Cross-Coupling and Oxidative Condensation Reaction: An Approach Towards Synthesis of Phenanthridine and Its Analogues
Authors: Nuree Yasin , Ray Jayanta
Published: June 2021

Phenanthridines belong to a very important class of nitrogen containing heterocylic compounds and constitute core structure of many natural alkaloids such as trisphaeridine and nitidine. Quarternarybenzo[c]phenanthridine alkaloids (QBA) represented by sanguinarine(SA), chelerythrine (CHE), and fagaronine (FA) exhibit antifungal and nematocidal properties and also serve as the core structure of broad range of medicinally active molecules showing anti-tumor activity, anti-viral property, anti-neoplastic or mutagenic activity through DNA-intercalation. Phenanthridines are also utilized for the synthesis of compounds of therapeutic interests such as anticancer platinum complex typified by phenanthriplatin antibacterial, anti-infectives, antprotozoal, antituberculosis, antitrypanosomiasis compounds. Although conventional synthetic methods towards their development showed their own advantages, they generally involved either multistep processes with low yield, or starting materials which are not readily available or requirement of prefunctionalization. Hence herein we present the development of an efficient and convenient synthetic methodology towards these versatile compounds.

In this study, data collection included surveys, audio-taped interviews, observations, and students' Chinese language test scores. Those participants were divided into two groups, the students took the children's self-satisfaction questionnaire, and the parents took the demographic survey separately. Besides, the content of audio-taped interviews was transcribed as statistical variances to find and identify patterns of the results.

    Those three research questions need to be answered in this study: 1. What are the attitudes and actions of those Chinese immigrant parents who do have regard to their Children's Chinese language and literacy learning? 2. Why do some parents feel challenged to maintain Chinese in the home and face the intense pressure of English usage outside society? 3. Is there any connection between Chinese heritage language proficiency and self-efficacy in learning? After the study, the results showed a positive relationship between Chinese heritage language proficiency and students' self-esteem. Parents who were most insistent on using Chinese in the home were most successful in maintaining their children's Chinese, and they also got a better score on the Chinese language tests.

Systemic Risk in Chinese Commodity Futures Markets: A Graph Theory Analysis
Authors: Yang Jinyu
Published: June 2021

This paper sets out to explore the contagion of systemic risk in Chinese commodity futures market based on specific tools of the graph-theory. More precisely, we use minimum spanning trees as a way to identify the most probable path for the transmission of prices shocks. In the sample of 30 kinds of Chinese commodity futures, we construct the MST and obtain the most probable and the shortest path for the transmission of a prices shock. We find that metal futures play an important role in commodity futures market and copper stands at the heart of the system (The core position of the system is very important for the transmission of system risk). And our results also reveal that when the risk occurs, the MST structure becomes smaller, leading to the most effective transmission path of risk becomes shorter.

Mengingat banyaknya pembangunan di suatu kawasan yang dilakukan tanpa mempertimbangkan aspek alamiah tapak. Salah satu kasus yang cukup penting diulas adalah pengolahan lahan berkontur. Bandung Utara memiliki karakteristik topografi tanah dengan kemiringan yang cukup besar bahkan beberapa memiliki kecuraman yang ekstrim. Berkembangnya kawasan Bandung Utara menjadi objek wisata atau villa pada saat ini merupakan suatu hal yang kadang kala tidak diperhatikan lagi. Skala prioritas pada aspek bisnis, menjadikan beberapa karakteristik lahan kontur alamiah mengalami perombakan besar-besaran. Akibatnya lingkungan alamiah menjadi rusak, erosi bahkan longsor. Penelitian terhadap kawasan ekowisata Cijaringao, kawasan Bandung Utara yang memiliki karakteristik topografi berkontur merupakan objek studi yang sesuai dengan tema tersebut. Tujuannya adalah menganalisa pengolahan dan pemanfaatan kontur pada fungsi wisata. Metode kuantiatif - normatif digunakan sebagai analisis pengolahan lahan kontur dengan mengujinya terhadap standar ideal pengolahan perancangan pada lahan berkontur. Harapannya,penelitian ini dapat membuka wawasan para perencana dalam merancang fasilitas (built environment) pada lahan berkontur.Kata Kunci : Kontur, lingkungan alamiah, ekowisata, Cijaringao ecoland AbstractThe importance of natural conservation of an area at this time is an important thought amid the issue of environmentally friendly zoning. Given the large number of developments in an area that are carried out without considering the natural aspects of the site. One of the important cases to review is contour land management. North Bandung has a characteristic topography of the land with a fairly large slope and some even have extreme steepness. The development of the north bandung area to become a tourist attraction or a villa at this time is something that is sometimes overlooked. The scale of priority in the business aspect has made some of the characteristics of the natural contour land underwent a major overhaul. As a result, the natural environment is damaged, erosion and even landslides. Research on the ecotourism area of Cijaringao, North Bandung which has a contour topographical characteristic is an object of study in accordance with this theme. The aim is to analyze the processing and utilization of contours in the tourism function. The quantitative - normative method is used as a contour tillage analysis by testing it against the ideal standard of design processing on contoured land. It is hoped that this research can open the insights of planners in designing built facilities on contoured land.Keywords: Contours, natural environment, ecotourism, Cijaringao ecoland

Bangunan eks kolonial merupakan warisan bernilai sejarah tinggi yang harus dilestarikan, salah satunya Gedung Negara Cirebon. Fungsi bangunan ini sebagai tempat penginapan tetap dipertahankan, di samping terdapat ruang yang menjadi area kerja dan pada masa depan direncanakan menjadi fasilitas sumber budaya. Dalam melakukan aktivitas dan kerja visual dibutuhkan cahaya alami dengan kuantitas dan sesuai agar pengguna tetap dapat memperoleh kenyamanan visual, dan hal ini sangat ditentukan oleh desain bangunan terutama orientasi bangunan dan bukaan cahaya; alokasi dan kedalaman ruang; dimensi, bentuk, posisi, dan spesifikasi bukaan cahaya; serta reflektansi permukaan. Terkait Gedung Negara yang telah ditetapkan menjadi bangunan cagar budaya dimana kondisi fisiknya harus dipertahankan, penting untuk dikaji apakah dengan desain yang ada sebagai bangunan eks kolonial, dapat memberikan kuat penerangan yang mendukung perolehan kenyamanan visual bagi penggunanya. Metoda analisis dilakukan baik kuantitatif dan kualitatif, dan pada analisis kuantitatif dilakukan pengukuran di loksi juga simulasi model menggunakan software Revit 2020 dan DIALux evo 8.2 yang hasilnya dibandingkan dengan standar kenyamanan visual terkait kuat penerangan. Diharapkan melalui penelitian ini diperoleh nilai manfaat agar dapat mengoptimalkan potensi cahaya alami bagi pengguna bangunan eks kolonial dengan tetap menjaga kelestariannya sebagai bangunan cagar budaya.  Kata kunci: desain bangunan eks kolonial, kenyamanan visual, pencahayaan alami

Efficiency and Performance Comparison Between Synchronous Reluctance and Induction Motor in Axial Flux Concept
Authors: GERÇEKCİOĞLU Harun Serhat , AKAR Mehmet
Published: June 2021

In this study, the Axial Flux Synchronous Reluctance Motor (AF-SynRM) with multiple barriers in its rotor is designed and it is aimed to compare the performance with the Axial Flux Induction Motor (AF-IM) with the same stator structure and dimensions. For an equal comparison, the motor dimensions and stator structure are chosen the same, only the rotor is changed. In the preliminary study of the designs, machine dimensions are calculated analytically and modeled with the 3D Finite Element Method (FEM). To optimize the saliency ratio, which is the most important factor affecting AF-SynRM performance, Genetic Algorithm (GA) based optimization is performed and the rotor geometry is changed. Thus, a suitable model is created for comparison. Torque, efficiency, input power, power factor, total loses and torque per amper parameters are analyzed. With the proposed comparison method, AF-SynRM obtains higher efficiency, power, torque per ampere and lower losses than AF-IM at the same power rating (2.2 kW). The AF-SynRM rotor will be a good alternative in applications where high efficiency and torque are required, with low cost-maintenance costs due to the absence of a squirrel cage and its structure without magnet.
