A Decenary Update on the Deep Eutectic Solvents in Heterocyclic Scaffold
Synthesis-A Green Solvent Approach
Authors: Kamanna Kantharaju , Badiger Krishnappa B. , Kamath Aravind 
Published: February 2023

Abstract:
Deep eutectic solvents (DESs) are a mixture of two or more chemicals (hydrogen bond donors
and acceptors) that are solid at room temperature, but combined at a unique molar ratio, presenting a
melting point recession and becoming liquid. These solvents emerged as an alternative to hazardous solvents
employed in various organic transformations and fulfilled the green chemistry concept. The convenience
of synthesis, recyclability, inexpensiveness, non-toxicity, high solvent capacity, high biodegradation,
low volatile organic character, and environmentally benign nature give DESs an edge over other
solvents. Due to the numerous benefits to present environmental concerns and the necessity to replace
hazardous solvents, the DESs solvent system is appealing to chemists in recent decades. The most important
role played by the DESs showed component interactions via covalent or ionic bonds, and is thus
considered a good candidate to replace ionic liquids or traditional solvents. The present review article
focuses mainly on recent highlights of DESs, preparation, properties and applications to various heterocyclic
molecule construction for the period 2012 to 2022.

Published: February 2023

Purpose of research. The most important task in the field of mechanical engineering is to increase production efficiency through the rational use of equipment, increase in labor productivity, and reduce the labor intensity of technological operations while ensuring the required quality. In manual production, only the working movements of the tool are mechanized. Installation, adjustment and replacement of the tool, as well as control over its condition, are carried out by the operator or the fitter. The solution to the problem of increasing the productivity of turning operations is possible only by automating auxiliary movements.One of several existing ways to reduce non-regrowth time is the automatic replacement of non-regrowth cutting inserts in turning tools. However, the known designs of such assembled cutters do not allow achieving the required quality of processing due to the ineffectiveness of damping vibrations arising during the cutting process. The machining accuracy during cutting largely depends on the design of the tool and the materials used in its manufacture. These materials in the construction of the tool dissipate vibration energy, thus reducing vibration and ensuring the required accuracy.The purpose and objectives of the development are to improve the quality of processing and tool life through design solutions that increase the rigidity of the cutters and significantly damping vibrations during turning. Methods. Use of high damping material to reduce vibration.Results. Increasing the efficiency of damping vibrations of the cutter due to vibration isolation of its prefabricated parts from the holder with a material with high damping.Conclusion. The proposed damping cutter with automatic change of the cutting insert allows you to achieve a technical result to improve the quality of processing, tool life and increase time between insert changes.

Published: February 2023

Purpose of research. Is to increase the degree of automation of contractual relations legal support of the parties as in the case of publishing activities through the development of model-algorithmic control and software for the automated creation and updating of texts of publisher-author license agreements.Methods. When analyzing the processes of automating legal activities in relation to the creation, development and updating texts of contracts, Russian and foreign technologies and software that allow automating the processes of contractual activities have been considered. Conceptual and set-theoretics models of the process of automated building texts of contracts have been proposed.Results. An original classification of tasks and ways of automating the legal activities including a list of promising information technologies have been proposed. Conceptual and set-theoretics models of the process of automated building texts of contracts have been developed; they differ in the use of a set of public acts, information resources, and expert information available as sources of information to create the necessary document in the selected subject area based on the algorithm of data verification, generation, visualization, contract updating, which provide contract creation and updating in an automated mode. An algorithmic model for automated processing of contract parameters which differs in the distribution of tasks between experts (a lawyer, a programmer) and software tools at has been developed. The main stages of the document life cycle involve creating, updating, deleting a contract, which, based on the event model, checks for updates in public acts and automatically corrects the text values of the parameter of the contract. The proposed solutions have been tested in case of a license agreement between an author of the article and the publishing house issuing Informatics and Automation journal.Conclusion. The development of model-algorithmic control and software for processing text information available from public acts, information resources provided by representatives of subject areas necessary for the automated generation, verification, and visualization of individual acts contributes to an increase in the degree of automation, reduces the time of preparation of legal documents that meet the requirements of existing public acts. Means of automating contractual activities should be built on the principle of openness, be dynamic, and also be externally controlled.

Authors: Plack Daniel L , Abcejo Arnoley S , Kraus Molly B , Renew J Ross , Long Timothy R , Sharpe Emily E 
Published: February 2023

Background
The dissemination of information about residency programs is a vital step in residency recruitment. Traditional methods of distributing information have been printed brochures, websites, in-person interviews, and increasingly, social media. Away rotations and in-person interviews were cancelled, and interviews were virtual for the first time during the COVID-19 pandemic.

Objective
The purpose of our study was to describe postgraduate-year-1 (PGY1) residents’ social media habits in regard to residency recruitment and their perceptions of the residency programs’ social media accounts in light of the transition to virtual interviews.

Methods
A web-based 33-question survey was developed to evaluate personal social media use, perceptions of social media use by residency programs, and perceptions of the residency program content. Surveys were sent in 2021 to PGY1 residents at Mayo Clinic in Arizona, Florida, and Minnesota who participated in the 2020-2021 interview cycle.

Results
Of the 31 program directors contacted, 22 (71%) provided permission for their residents to complete the survey. Of 219 residents who received the survey, 67 (30%) completed the survey. Most respondents applied to a single specialty, and greater than 61% (41/67) of respondents applied to more than 30 programs. The social media platforms used most regularly by the respondents were Instagram (42/67, 63%), Facebook (36/67, 54%), and Twitter (22/67, 33%). Respondents used the program website (66/67, 99%), residents (47/67, 70%), and social media (43/67, 64%) as the most frequent resources to research programs. The most commonly used social media platforms to research programs were Instagram (38/66, 58%), Twitter (22/66, 33%), and Doximity (20/66, 30%). The type of social media post ranked as most interesting by the respondents was “resident life outside of the hospital.” In addition, 68% (39/57) of the respondents agreed or strongly agreed that their perception of a program was positively influenced by the residency program’s social media account.

Conclusions
In this multispecialty survey of PGY1 residents participating in the 2020-2021 virtual interview season, respondents preferred Instagram to Twitter or Facebook for gathering information on prospective residency programs. In addition, the program website, current residents, and social media platforms were the top-ranked resources used by prospective applicants. Having an up-to-date website and robust social media presence, particularly on Instagram, may become increasingly important in the virtual interview environment.

Authors: Lestari Diana , Wahyuningsih Tutik Dwi , Purwono Bambang 
Published: February 2023

The nitrovanillin azine (NA) has been successfully synthesized and examined as a colorimetric chemosensor for sulfide anion detection. The NA was synthesized using two steps reaction. Vanillin was reacted with concentrated nitric acid to form 5-nitrovanillin (NV) then the NV was condensed with hydrazine hydrate to produce the NA. The NA was obtained and fully elucidated by FTIR, 1H-NMR, 13C-NMR, and GC-MS spectrometer. The NA activity for anionic chemosensor was then carried out on several anions such as F⁻, Cl⁻, Br⁻, I⁻, S2⁻, CN⁻, HCO3⁻, AcO⁻, H2PO4⁻, N3⁻, NO2⁻, SCN⁻, ClO3⁻, and NO3⁻. The chemosensor tests showed NA was only selective for S2− in DMF:HEPES buffer (9:1, v/v, 10 mM, pH = 7.4) giving color change from light yellow to dark green. The LOD value was 1.43 × 10−5 M and the interaction model of NA-S2− indicated deprotonation mode between the -OH group with sulfide anion in a ratio of 1:1. The NA chemosensor can be applied for qualitatively analysis of sulfide anion using filter paper strips and quantitatively analysis of sulfide anion in tap water.

Published: February 2023

In this study, ZnO thin films doped with Al (AZO) and Cu (CZO) were fabricated on a glass substrate via sol-gel spin coating. The influence of 1 atomic % Al and Cu doping on the structure, morphology, as well as optical properties of ZnO thin film was then analyzed with X-ray diffraction (XRD), atomic force microscopy (AFM), and UV-Vis spectroscopy. XRD analysis revealed that all samples possessed hexagonal wurtzite crystal structures with 3 to 4 preferred orientations. Al and Cu doping caused a decrease in crystal size, while the lattice strain (e) and dislocation density (ρ) were increased. AFM indicated that Al and Cu doping reduced the surface roughness of the ZnO thin film. Optical measurement showed that all samples exhibited high transmittance (> 80%) in the visible light region. Transmittance was reduced after doping, while the band gaps for ZnO, AZO, and CZO thin films are 3.26, 3.28, and 3.23 eV. This study showed that an addition of 1 atomic % transition metal (Al and Cu) greatly influences the structure, morphology, and optical properties of ZnO thin film.

Published: February 2023

Layered double hydroxide (LDH) of Ni/Al was synthesized by coprecipitation method at pH 10 followed by the formation of composite with carbon-based material i.e., biochar (B) and graphite (G) to form Ni/Al-B and Ni/Al-G. Materials were characterized by XRD powder, FTIR, BET surface area, thermal analyses, and SEM analysis. The regeneration process and adsorption evaluated the performance of materials toward iron(II) [Fe(II)] from an aqueous solution. The results showed that the surface area of Ni/Al-B (428.94 m2/g) was increased mainly up to twenty-nine-fold than Ni/Al LDH (15.11 m2/g), while Ni/Al-G (21.59 m2/g) had slightly increased than pristine LDH. Composite of Ni/Al-B had reusability properties for Fe(II) adsorption up to five cycles and showed higher structural stability. The adsorption capacity of Ni/Al-B was 104.167 mg/g and can be a potential adsorbent to remove Fe(II) from an aqueous solution.

吠陀經典有無比的神聖性，吠陀吟誦是印度宗教祭祀儀式的重要内容，必須正確發音。婆羅門必須每天精勤地記誦吠陀。直到今天，仍有婆羅門吟誦吠陀，從事宗教祭祀活動。靠這種嚴格無誤的口耳相傳的記誦，保存了四吠陀豐富的内容，也因此保存了基本的吟誦方法和吠陀三聲。古典梵語保持了吠陀梵語的基本語音結構特徵。《波你尼經》研究的吠陀三聲也應該是當時活著的自然的語言。婆羅多牟尼《舞論》指出吟誦的高調、低調、降調，和吠陀三聲應該是一回事。梵語戲劇戲文既從吠陀中擷取吟誦、歌唱、表演，就可能從中擷取吟誦吠陀的三聲。梵語戲劇有吠陀頌詩，用吠陀三聲是很自然的。吠陀三聲確實以某種方式延伸到古典梵語，延伸到古典梵語的戲劇文學作品。吠陀三聲還應該進入中土的佛經轉讀，因而啓示人們認識漢語四聲現象。Vedas sutra is very divine. Vedas recitation with correct pronunciation was important for sacrificial ceremony in Indian Religions. Brahman recited Vedas and engaged religious ceremony until now. By words of mouth, four Vedas were kept, so was the basis way of recitation and three tones of Vedas. Ancient Sanskrit preserved the tone structure characteristics of the Vedaic. Three tones of Vedas re-searched in Astlātura were likely to be all-pervading language at that time. Nātyasāstra by Bharatamuni pointed that high tone, low tone and falling tone should be the three tones of Vedas. Since Sanskrit theatre selected recitation, singing and performance from Vedas, it might select three tones for recite Vedas. Sanskrit theatre contained Vedas odes, so it was natural to use three tones. It was truth that three tones of Vedas was kept by the ancient Sanskrit theatre. Three tones of Vedas might be accepted by Zhuandu in Chinese sutra, which enlightened people how to understand four tones in Chinese.

中國文學歷史上，婦女文學創作之母系傳承現象衆多，但以往的研究，大多注目於同一歷史時期此種現象的介紹與解讀，本文則以跟蹤研究的方法，剖析了一個母女相傳五代之久、歷經乾隆、嘉慶、道光、咸豐、同治、光緒、宣統以至民國的文學創作個案，揭示了從清中期到近現代，中國婦女文學在社會背景、女性意識、地域分佈、美學風格等方面的諸多變化，展現了我國知識女性由古代進入現代的坎坷歷程。In the development of Chinese literature, matrilineage is a very common phenomenon in female literary practice. Studies of this issue used to focus on specific historical eras. The present thesis, however, traces the materilineage through five generations, extending from individual literary practices during the reign of Qianlong, Jiaqing, Daoguang, Xianfeng, Tongzhi, Guangxu, Xuantong until that in the National Government period. The thesis intends to demonstrate the changes that Chinese female literature has experienced through mid Qing Dynasty to modem times in several aspects such as social background, female consciousness, geographic and aesthetic features; meanwhile, it also attempts to delineate the thorny path that carries Chinese female intellectuals from ancient era to modem times.
