Comparison of monophosphine and bisphosphine precatalysts for Ni-catalyzed Suzuki-Miyaura cross-coupling: understanding the role of ligation state in catalysis
Authors: Borowski Julia , Newman-Stonebraker Samuel , Doyle Abigail
Published: March 2023

Practical advances in Ni-catalyzed Suzuki-Miyaura cross-coupling (SMC) have been limited by a lack of mechanistic understanding of phosphine ligand effects. While bisphosphines are commonly used in these methodologies, we have observed instances where monophosphines can provide comparable or higher levels of reactivity. Seeking to understand the role of ligation state in catalysis, we performed a head-to-head comparison study of Ni SMCs catalyzed by mono and bisphosphine precatalysts using six distinct substrate pairings. Significant variation in optimal precatalyst was observed, with the monophosphine precatalyst tending to outperform the bisphosphines with electronically deactivated and sterically hindered substrates. Mechanistic experiments revealed a role for monoligated (P1Ni) species in accelerating the fundamental organometallic steps of the catalytic cycle, while highlighting the need for bisligated (P2Ni) species to avoid off-cycle reactivity and catalyst poisoning by heterocyclic motifs. These findings provide guidelines for ligand selection against challenging substrates and future ligand design tailored to the mechanistic demands of Ni-catalyzed SMCs.

Published: March 2023

The growing global plastic waste challenge requires the development of new plastic waste management strategies such as pyrolysis that will enable a circular plastic economy. Pyrolyzed plastics thermally convert into a complex mixture of intermediates and products that includes their constituent monomers. Developing optimized, scalable pyrolysis reactors capable of maximizing the yield of desired olefinic products requires a fundamental understanding of plastic pyrolysis mechanisms and reaction kinetics. Accordingly, the intrinsic reaction kinetics of polypropylene (PP) pyrolysis have been evaluated by the method of Pulse-Heated Analysis of Solid Reactions (PHASR), which enables the time-resolved measurement of pyrolysis kinetics at high temperature absent heat and mass transfer limitations. The yield of gas chromatography-detectable light species (
Theories of Sustainable Finance
Authors: Ozili Peterson K.
Published: March 2023

This paper attempts to formulate new theories of sustainable finance, meeting a need to establish a set of propositions that can help us understand the behaviour and actions of economic agents towards sustainable finance. The paper used a literature survey to establish a theoretical relationship between sustainable finance and the actions of economic agents. The paper proposed six theories of sustainable finance, namely, the priority theory of sustainable finance, the resource theory of sustainable finance, the peer emulation theory of sustainable finance, the life span theory of sustainable finance, the positive signalling theory of sustainable finance, and the system disruption theory of sustainable finance. These theories offer believable explanations for the behaviour and actions of economic agents towards sustainable finance. Academics, policy makers, economists, researchers and students will find these theories very useful in their work in sustainable finance.
Entre a tradição e a modernidade: o artesanato têxtil doméstico de Resende Costa, MG
Authors: Soares Junior Glauber , Alves de Carvalho Angelita
Published: March 2023

Esse artigo foi desenvolvido com a finalidade de compreender a produção do artesanato têxtil doméstico no município de Resende Costa, em uma perspectiva histórica e contemporânea. Em termos de metodologia, trata-se de um estudo de caso realizado de forma online, em que foram entrevistados 40 tecelões (e pessoas que já trabalharam no ofício) da localidade, sendo 20 homens e 20 mulheres. Os dados foram organizados e analisados através de uma análise de conteúdo por redes temáticas. No que toca aos principais resultados, compreende-se que, em suma, o artesanato têxtil é produzido no domicílio, sendo desenvolvido principalmente por mulheres. No passado, a produção era totalmente manual, desde o plantio até o acabamento dos artefatos, sendo confeccionadas menores quantidades de objetos e de forma mais lenta. Na atualidade, a maneira de tecer se mantém, contudo, a matéria prima básica para a produção passa a ser industrial e a produção atinge status de manufatura, sendo fabricadas grandes quantidades de artesanias de forma mais simplificada, localizando o ofício entre a tradição e a modernidade.
Influenciadoras digitais de moda como educadoras: reflexões a partir do pensamento freiriano
Authors: Barroso Arraes Rocha Silva Lair , Palavecini Andressa Carla , Coutinho Pépece Olga Maria
Published: March 2023

Uma das funções da moda é a da comunicação. Ela envolve a interpretação adequada de símbolos e significados que são aprendidos e compartilhados socialmente, de modo que consumir moda como comunicação requer um aprendizado sobre o sistema da moda. Nos últimos anos, surgiu um novo intermediário que atua informando sobre os códigos que compõem a linguagem da moda: os influenciadores digitais. Na presente pesquisa, buscamos identificar se influenciadoras digitais realmente ensinam às suas seguidoras a linguagem da moda para que a comunicação almejada seja alcançada. Para isso, realizamos uma netnografia com influenciadoras digitais de moda, além de entrevistas semiestruturadas com profissionais de marketing de influência, pedagogas, influenciadoras digitais e suas seguidoras. Estudamos o caráter educacional dos discursos das influenciadoras baseados em quatro categorias propostas nas obras do educador e filósofo brasileiro Paulo Freire: formação e legitimidade, centralidade da mensagem, diálogo e conexão com a realidade. Com isso, nós chamamos atenção para quais os elementos necessários para considerar um influenciador digital como educador, incorporando a temática ao campo do consumo, da moda e das redes sociais.
Assemblages de consumo na moda: uma visão sociomaterial para além das abordagens dialógicas
Authors: Braga Soares Pinto Camila , Carvalho Suarez Maribel , Celso de Miranda Ana Paula
Published: March 2023

Este estudo busca entender como se constituem as relações sociomateriais entre humanos e não humanos para além da dialogicidade, ou seja, a relação entre o consumidor e um objeto de consumo específico. Para isso, baseia-se na abordagem das Ontologias orientadas a objetos (HARMAN, 2018), considerando os armários como unidades centrais na composição de assemblages, que reúnem diversos objetos em relação entre si. O percurso metodológico construído visou à experiência centrada em objetos, observando como a sociomaterialidade em ação opera de maneiras distintas a partir dessas interações coletivas. A partir da análise de armários como uma assemblage de consumo (CANNIFORD e BAJDE, 2016), o trabalho evidencia um arcabouço conceitual alternativo capaz de oferecer aos estudos de moda novos recursos teóricos para se entender a relação entre diversos objetos.
J.H. JUNG-STILLING AND A.T. BOLOTOV: RECEPTION OF THE GERMAN MYSTIC’S IDEAS IN THE NON-ACADEMIC ENVIRONMENT
Authors:   Herzen University, Artemyeva Tatiana V.
Published: March 2023

German mystic and theosophist Johann Heinrich Jung-Stilling (1740–1817) gained immense popularity in Russia at the beginning of the 19th century. This fact is proven by numerous translations of his works and reminiscences of his ideas in literary texts and memoirs of the time. Scientist, philosopher, and writer A.T. Bolotov (1738–1833) was his great admirer, follower, and popularizer. The reception of Jung-Stilling is reflected both in Bolotov’s poetic experiments and his works “The old man with his grandson, or Conversations of an old man with his young grandson” (1822), “Assumed events in the Afterlife” (1823) and “About the souls of dead people” (1823) written in the form of Platonic dialogues. Bolotov’s example makes it possible to analyze the reception of the German mystic’s ideas and their dissemination in the non-academic environment.

EUGENE BURNOUF (1801–1852) AND HIS WORK “INTRODUCTION TO THE HISTORY OF INDIAN BUDDHISM”
Authors:   Institute of East Culture, Gunskii Aleksei Yu.
Published: March 2023

The article examines the life and ideas of Eugene Burnouf (1801– 1852), one of the leading European Buddhologists of the 19th century. His work “Introduction to the History of Indian Buddhism” is considered the first scientific study of Indian Buddhism. The human image of the Buddha recreated in this work formed the basis of the concept of the “historical Buddha”, which prevailed at the end of the 19th century in Buddhist studies. For a long time, Burnouf’s work was considered outdated, but an English translation published in 2010 brought this research back into scientific circulation. The article briefly describes Burnouf’s biography, examines the state of European knowledge about the Buddha and Buddhism by the beginning of Burnouf’s activity. The article analyzes the image of the Buddha created by Burnouf as a preacher of morality and early Buddhism as a simple moral teaching. It is shown that such a representation is due to the classification of texts adopted by Burnouf. The author shows the shift of his research interest from the Mahayana sutras to earlier texts. The final part of the article describes some new ideas and possibilities arising from the modern reading of Burnouf’s text, in particular, the revision of the concept of the “historical Buddha” and the genesis of the terms “Mahayana” and “Hinayana”. A hypothesis is proposed about the possible influence of the “Introduction to the History of Indian Buddhism” on L.N. Tolstoy
UGARITIC GOD ḤORĀN. POSSIBLE SYRO-CANAANITE ORIGINS OF THE SERPENT OF BRASS
Authors:   Russian State University for the Humanities, Mikhailova Natal’ya V.
Published: March 2023

The article considers a variant for the origin of the Serpent of brass also known as Nehushtan. Following the hypothesis of the pre-monotheistic origin of the image, it can be assumed that the Serpent of brass was not originally an attribute of Yahve, but was an idol or votive of one of the Semitic deities associated with healing. The most appropriate god in terms of the worship time and common attributes is the Syro-Canaanite Ḥorān, whose veneration was widespread during the late Bronze Age. Being a deity representing the forces of primordial chaos, Ḥorān was considered the creator of poisonous snakes and, possibly, was originally a dragon himself. According to the currently known cuneiform texts of Ugarit, Ḥorān was a conjurer, healer and defender against snakebites. Also, one of the most important functions of Ḥorān was to protect the royal power granted by the gods from the unworthy. The name of the deity Ḥorān is etymologically close to the creature Seraph in Hebrew, which in turn was represented as a flying, fire-breathing serpent. In the Tanakh, traces of the existence of Ḥorān in the culture of the Jews are preserved in the form of stable phraseological units using his name, while each time he appears in the context of the measure of God’s righteous judgment: all-consuming and incinerating, like fire, anger, striking the wicked, but not scorching the righteous. All of the above suggests a fairly ancient origin of the Serpent of brass and its connection with the Ḥorān as an independent pagan deity or spirit in the service of the Lord.
BIM-technologies in solving the problems of construction waste management
Authors: Shilkina Svetlana
Published: March 2023

During the process of new construction and demolition of old buildings, a huge amount of waste is generated. In some regions, the construction industry is responsible for more than half of the solid waste generated. From a technical point of view, it is impossible to completely eliminate construction waste, but it must be managed to minimize the negative impact on the environment. The goal of all participants in the project work program should not only be to complete the construction of the building as soon as possible, but also to comply with environmental requirements. In developed countries, for several decades, the rules for handling such waste have been introduced at the legislative level, and they are constantly being improved. At the state level, laws are passed regarding the recycling and reuse of building materials in order to reduce waste. Scientists are also developing waste management strategies and models for construction and demolition. As a result, up to 90% of such waste "gets a second life", i.e. reused in the manufacturing process. In Russia, this problem has not yet been given enough attention, which is why no more than 30% of construction waste is reused. This article analyzes the causes of waste generation in the construction sector, highlights their main categories. To solve the problem, recommendations are proposed on some promising areas for the development of the construction industry. The need to amend the legal framework governing the process of construction and demolition (C&D) was noted. As an innovative vector of development, the potential of building information modeling (BIM) technology for managing the design and construction of buildings, including waste management, is being explored. It is noted that BIM allows you to effectively manage construction and demolition waste, avoiding problems at all stages of the building life cycle. As a result of the study, recommendations were developed for the implementation of specific measures for the construction waste management strategy using BIM.
Lesson Learned From Static Model Uncertainty Analysis
Authors: Praja I.T.A
Published: March 2023

This paper documents lessons learned from conducting uncertainty analysis for 3D static modeling. Example cases, evaluation techniques and a proposed guideline are presented to resolve misconceptions in probabilistic studies. The technological advancements nowadays have allowed thorough probabilistic studies to be conducted. In most 3D static modeling software, a recorded 3D modeling workflow can be incorporated with various variables and run as an experimental design with several runs. However, the lack of transferred knowledge and publications regarding probabilistic guidelines has led to many inconsistencies, misconceptions, and confusion about the fundamentals, during designing, running, or post-run analysis. For example, during running analysis, the result is inconsistent between the field-level median model (P50) with zone-level median models. Later, this could raise a history matching issue since it obscures unreliable zone-level recovery factors due to overlapping in-place among tanks. An example from the post-run analysis is a missing P50 from the list due to an even number of experiments. Every tool has different methods of processing and visualizing statistics output. Assuming a similar definition and approach can lead to confusion. A strategy to assign a facies model that represents a geo-body at a specific time or zone is described by considering dependency and hierarchy among variables. The result is calculated, visualized, and ranked at the zone level to avoid percentile misconceptions. Then, the corresponding percentile from each tank is combined to build a consistent field-level model. It is essential to understand which statistical approach a tool uses, and whether it uses a function to determine the percentile inclusive/exclusive of the first and last values in the array. Integration work could identify problem earlier and then resolve them before further effort. This paper aims to guide in building a consistent uncertainty analysis modeling and avoid unnecessary rework due to misconception.
De-Risking Exploration Well in A Mature Basin, Jabung Block, South Sumatra Basin: Application of Avo Analysis in A Sub-Unconformity Play
Authors: Muhtar L.K
Published: March 2023

The Late Oligocene to Late Miocene reservoir as well as basement in Jabung block has been proven filled by hydrocarbon. One of the unexplored intervals in this block is the sub-unconformity (Pre-TAF) play as angular unconformity, which is older than the Lower Talang Akar Formation (LTAF). However, this play has many risks, for instance in the geometry and quality of the reservoir. To de-risk the play, this study proposes to characterize the reservoir by Amplitude Variation with Offset/Angle (AVO/AVA) method for a better understanding of reservoir conditions. Rock physics analysis and AVO forward modeling provide information about reservoir quality. Moreover, the AVO attribute gives reservoir geometry. This study finds that Pre-TAF play reservoir is categorized AVO class 2 with negative value in both intercept and gradient, which indicates good reservoir quality similar to LTAF oil and/or gas reservoir. Several channels are well identified by the P*G AVO attribute that is distributed from basement high in Southwest to basin depocenter in Northeast NEB field. As the result of this study to prove the potential of Pre-TAF play, we are proposing EXPL-Plan-1 well as a play opener to unlock hydrocarbon in this interval.

Simulation of Load Behavior Based on Perturb-Observation Method in Non-Isolated Boost Converter for Maximum Power Point Tracking of Thermoelectric Generators
Authors: MAMUR Hayati , AKYILDIZ Çiğdem , ÜSTÜNER Mehmet Ali
Published: March 2023

The efficiency of thermoelectric generators (TEGs) is quite low. To operate the TEGs at the maximum power point (MPP), the internal resistance of the connected load and the TEG must be equal. This is not always possible. For this, converters containing the maximum power point tracking (MPPT) algorithm tracking MPP are placed between the TEG and the load. These converters cannot perform MPPT on every connected load value. The aim of this study is to investigate at which load values MPPT can be performed in non-isolated boost converters by using perturb & observation (P&O) method. For this purpose, a 50 W converter was designed with a 45.76 W TEG in MATLAB/Simulink environment. Load resistance value has been increased starting from the minimum value up to 5.84 ohm being the internal resistance value of the TEG. For this case, the amount of error in MPPT was large up to the internal resistance value of the TEG. In other words, the P&O algorithm could not perform MPPT. When the load resistance value started from 5.84 ohms and increased to larger values, MPPT could be performed by means of the non-isolated boost converter with the P&O algorithm.

Authors: Nitika Sharma  , Ishwerpreet Kaur Jawanda  , Thomson Soni  , Vijay Prabha
Published: March 2023

Objective: Extraction of proteins from tissues is a key step to study the protein structure and function. There is no set of universal protocols because of the enormous chemical and physical variety of both proteins and the sample sources. Hence, in this study a comparison of different methods for protein extraction from mouse ovarian tissue was carried out. Methods: Intravaginal dose of 20µl of Phosphate buffer saline was given to 7 mice for ten consecutive days followed by extraction of ovaries. For comparison, seven different protein extraction protocols from Protocol 1 to Protocol 7 were used. The supernatant was first quantified with Bradford assay to determine the total protein yield followed by SDS-PAGE analysis. Results: Highest protein yield of 1.13 mg/ml was attained after supplementing 1% v/v protease inhibitor cocktail in PBS. In total, 13 protein bands were detected by the extraction protocol 2 and 11 protein bands by the extraction protocol 1. 11 protein bands were detected in the range 180 kDa to 22 kDa following Protocol 3 and 4. Extraction with lysis buffer 1 resulted in 7 visible protein bands of molecular weight 182 kDa to 35 kDa range. Only 6 protein bands were observed in the range 182 kDa - 35 kDa following lysis buffer 2 method. For lysis buffer 3, ten visible protein bands were detected in range of 195 kDa - 13 kDa. Conclusion: Based on the protein extraction efficiency of Protocol 1, optimal combination of Phosphate buffer saline (pH 7.2) and protease inhibitor cocktail followed by hand-homogenization is suggested for protein extraction from mouse tissues.

Published: March 2023

The Philippines’ risk communication system relies on information dissemination, which disregards local capacity for managing risk. This research aimed to examine risk communication in Roxas City, an important economic center working on capacitation after damage by Supertyphoon Haiyan. Guided by Encoding-Decoding theory, the researcher interviewed government officers and facilitated discussions at coastal and inland communities. The researcher found that local government viewed communities as audiences who intuitively knew what to do with scientific information. The coastal community had indigenous knowledge but acted based on fear of sanctions. The inland community discussed information from media, which led to community decision-making. These findings imply that local governments should consider the role of social networks unique to different communities when planning risk communication and hazard response.

Published: March 2023

Bu araştırmada okul öncesi ve sınıf öğretmenlerinin hayat boyu öğrenme ve uzaktan eğitime yönelik tutumları incelenmiştir. Araştırma nicel araştırma yöntemlerinden tarama modeli ile desenlenmiştir. Araştırmanın örneklem grubunu İstanbul’un bir ilçesindeki kamu ilkokullarında ve bu okullar bünyesinde hizmet veren anasınıflarında görev yapan 398 öğretmen oluşturmuştur. Veri toplama araçları olarak “Yaşam Boyu Öğrenme Tutum Ölçeği” ve “Öğretmenlere Yönelik Uzaktan Eğitim Tutum Ölçeği” kullanılmıştır. Verilerin analizinde SPSS 22 paket programı ve DFA için ise AMOS programı kullanılmıştır. Gerçekleştirilen analizlere göre öğretmenlerin hayat boyu öğrenme tutum düzeyleri yüksek ve uzaktan eğitime yönelik tutum düzeyleri ise düşük olarak bulunmuştur. Ayrıca öğretmenlerin hayat boyu öğrenme ve uzaktan eğitime yönelik tutum düzeylerinin cinsiyet, branş ve meslekî kıdeme göre anlamlı bir şekilde farklılaşmadığı ortaya çıkmıştır. Fakat öğretmenlerin hayat boyu öğrenme tutum düzeylerinin Öğrenme İsteksizliği boyutunda kadın ve okul öncesi öğretmenlerinin lehine anlamlı bir şekilde farklılaştığı belirlenmiştir. Bu bağlamda erkek ve okul öncesi öğretmenlerinin öğrenme isteksizliklerinin azaltılması yönünde kendilerine hizmet içi eğitim verilmesi; ayrıca bu öğretmen gruplarının öğrenme isteksizlikleri altında yatan sebeplerin nitel araştırmalarla incelenmesi önerilmektedir.

Murder and partial resurrection of the Halles de Baltard/Callet
Authors:   Universidade de Coimbra, Murtiunho Vitor
Published: March 2023

For more than eight hundred years, the city of Paris had grown accustomed to viewing the Halles area as a lived-in space where a flourishing commerce was practised and which was an appropriate place to purchase basic necessities. But, as in many other situations, everything has its moments of glory, and the conditions and aspects that lead to decadence are almost never of sublimation. The remarkable success of the novel The Womb of Paris, published in 1873, masterfully conceived by Émile Zola, gave prominence to a marketplace that quickly exceeded the literary imagination and distinguished itself as an urban space of excellence.

There is no doubt that the first objective to pursue when developing the design of any structure is to ensure that it is safe. First and foremost Moreover, safety presupposes that the conditions for static equilibrium are met at all circumstances to which the structure will be subjected during the period of time of its service life. Secondly, it must be guaranteed that its strength always exceeds, during that same period, the maximum stress intensities to which it may be subjected. The national structural safety regulations and international standards, define the circumstances and loads to be considered in the projects of the various structures, depending on the type of construction they support.

DEVELOPMENT OF INTELLIGENT CONTROLLER FOR POWER RIPPLE MITIGATION OF DFIG BASED WIND ENERGY SYSTEM
Authors: Vyas Garima . , Vyas Shripati  .
Published: March 2023

This study offers an adaptive neuro-fuzzy controller (NFC) for a wind energy conversion system (WECS) based on a doubly fed induction generator (DFIG) that may run in standalone mode. The adaptive- network-based fuzzy inference system (ANFIS) architecture is the foundation upon which the NFC is built since it offers the singular benefit of rapid convergence while integrating the resilience of fuzzy logic and flexibility of neural network algorithm. The load side converter (LSC) control of ANFIS is intended for the independent operation of DFIG-WECS. By keeping output voltage consistent, the suggested approach shows increased dynamic performance under conditions of fluctuating wind speed and load. Due to the precise control of the LSC, the supply frequency to the load is kept consistent even while the turbine rotation changes with changing wind speed. The rotor side converter's proportional-integral (PI) control maintains the flux alignment. The simulation outcomes demonstrate the controller's exceptional performance through its effective management of supply frequency and load-voltage under variations in wind speed and demand load power.
