A History of Hyperactive Chemistry on the Web: From Text and Images to Objects, Models, and Molecular Components
Authors: Rzepa Henry S.
Published: April 2022

The chemical application of the Internet over the last decade is reviewed, and lessons from the experience set out. In particular, we emphasize that to create a high quality, indexed and structured chemical resource using this technology, new standards and methodologies have to be defined
and adopted. One particular change, from the traditional use of text and illustrations in printed journals, to the deployment of object-based models built from, e.g., molecular components is discussed in more detail.

Published: April 2022

Термокарст является одним из ярких процессов, характеризующих динамику мерзлотных ландшафтов. Он представляет процесс проседания грунта вследствие оттаивания подземного льда. Под воздействием внешних факторов, таких как изменение климата, лесные пожары, вырубки лесов, нашествие шелкопряда и т.п., возникает ускорение процесса деградации многолетнемерзлых грунтов (ММГ). Так же усугубляет ситуацию высвобождение парниковых газов, заточенные в ММГ, которые, в свою очередь, ускоряют процесс потепления климата. Изучение термокарста позволяет оценить масштабы деградации ММГ и провести количественную оценку влияния на потепление климата.Рассмотрены проявления термокарстовых процессов на льдонасыщенных грунтах Янского плоскогорья. Приведены климатические условия исследуемого участка, а также обзорные геоморфологические и литологические особенности распространения грунтов на ней. Оценена деградация многолетней мерзлоты под воздействием лесных пожаров. Рассчитано оттаивание подземных льдов на участке «Чогоро» по классификации цифровой модели рельефа с помощью дешифрирования снимков с беспилотных летательных аппаратов. Основными методами работ являются ландшафтно-криоиндикационные и дистанционные. Обработка аэрофотоснимков велась в программных обеспечениях Topodrone, Agisoft metashapeи ArcGIS. Приведен пошаговый метод подсчёта объема вытаявшего льда на двух участках. Выявлены темпы деградации мерзлых грунтов для ключевых участков в пределах от 5,2 до 10,5 см/год. Объем вытаявшего льда составил 16364 м3 и 17985 м3.Сравнительный анализ форм рельефа, полученными с цифровых моделей рельефа по данным аэрофотосъемки выявил хорошую корреляцию с цифровой моделью поверхности по данным космических снимков, что подтвердилось по данным полевых измерений. Объем вытаявшего льда указывает на масштабные высвобождения парниковых газов в атмосферу, ускоряя темпы глобального потепления. Темпы деградации ММГ после лесных пожаров на льдистых грунтах безусловно активизируются или ускоряются.

Доклад на конференции «Системный мир Богданова А.А.» 9-10 декабря 2021 г., Финансовый университет при правительстве Российской ФедерацииЛюбое формирование систем происходит на основе целевой установки. Но откуда берутся сами цели? В научных трудах этому вопросу либо вообще не уделяется места, либо существует односторонний взгляд, что цели формируются более глобальный системой. В первом случае теория утрачивает свою завершенность и целостность. Во втором – приводит к неправильному пониманию системности мироздания. Оно воспринимается как нагромождение системных матрёшек, последней из которых непременно должен быть Бог.Цель доклада прояснить этот вопрос и предложить своё решение. Научная новизна доклада заключается в том, чтобы прояснить взаимосвязи зарождения системы с окружающей средой.Данное исследование позволяет лучше понять процессы происходящие в окружающем нас мире, расширить его философские трактовки. Сузить и конкретизировать системные поиски. Прояснение этого вопроса радикально изменяет само понятие «система».

Any formation of systems occurs on the basis of a goal setting. But where do the goals themselves come from? In scientific works, this issue is either not given place at all, or there is a one-sided view that goals are formed by a more global system. In the first case, the theory loses its completeness and integrity. In the second, it leads to a misunderstanding of the systemic nature of the universe. It is perceived as a heap of system nesting dolls, the last of which must certainly be God.The purpose of the report is to clarify this issue and propose a solution. The scientific novelty of the report lies in clarifying the relationship between the origin of the system and the environment.This research allows us to understand the processes better which taking place in the world around us, to expand its philosophical interpretations. Narrow and flesh out system searchе. Clarification of this issu radically changes the very concept of «system».
Modification of the Basic Dilution Equation for the Programming of Serial Dilutions
Authors: Bassa Babu , Uppu Rao
Published: April 2022

Stock solutions made with accurately weighable quantities of biologically active compounds often do not result in physically measurable delivery volumes, delivered to cell cultures, assay buffers etc., consequently requiring delineation of the serial dilution steps of the stock solution in a case by case manner. The basic dilution equation (C1V1 = C2V2) alone is not amenable for the programming and computerization of the serial dilutions. The best solution to this dilemma is to develop an equation with the delivery volume as one of the variables. We present here a modified dilution equation (MDE) that has the delivered volume as one of the variables. We demonstrate with examples how the equation can be used in delineating serial dilution steps either manually or through programming. The equation is D = C1p/C2V2, where D is the fold dilution required of a stock solution of C1 concentration which is diluted and delivered (pipetted) at a volume p to cell culture media, assay mixture etc., of volume (V2 – p), to achieve a final concentration of C2. The equation is useful when the volume of the stock solution made up to the final volume as calculated with basic dilution equation is not measurable physically. An Android application for the dilution/Serial dilution instructions, developed based on the MDE and named as “TheDilutionApp” is now available for free for a limited period at "github.com/bbassa9824/TheDilutions/releases". Downloading instructions are given under the “Results and Discussion” section of this preprint. A video demonstration of the downloading instructions and use of the Android application is available at https://youtu.be/3zuRvEz2HiA. A windows version of the same application is available as part of a larger program (8).
Entanglement of electrons and nuclei during ultrafast excitation: A most compact representation of the molecular wave function
Authors: Remacle Francoise , Blavier Martin , Gelfand Natalia , Levine Raphael D.
Published: April 2022

Ultrafast pumping displaces both electrons and nuclei from equilibrium so that the wave function is a double sum of separable terms for the dynamics of the electrons and nuclei. We convert the double sum into a single one by a matricization of the wave function, that is equivalent to the Schmidt decomposition. If more than one term needs to be included in this sum, the wave functions exhibit entanglement of electrons and nuclei. We discuss generating the best exact separable expression for the entangled molecular wave function. Then an approximation with a minimum number of single terms is obtained via Singular Value Decomposition, SVD. Two contrasting examples, LiH and N2, are used as an illustration. In the energy range accessible by a UV excitation, the two differ in their adiabatic electronic dynamics. During the nuclear motion the singlet states of N2 remain bound while the states of LiH are dissociative.

Authors: Yang Tingyuan , Tang Shuli , Kuo Syuan-Ting , Freitas Dallas , Edwards Madison , Yan Xin
Published: April 2022

Unsaturated lipids constitute a dominant portion of lipids in mammalian cells and often exist as a mixture of isomers. Knowing concentrations of lipids is essential for understanding their functions in physiology and diseases. Herein, a novel aziridination-based isobaric tag labeling strategy is developed for isomeric characterization and accurate quantification of unsaturated lipids. This strategy allows (i) determination of lipid double bond positional isomers, (ii) quantification of unsaturated lipids and lipid isomers, and (iii) improvement of ionization efficiencies of nonpolar lipids. The power of the method has been demonstrated in characterization and quantification of various categories of lipids such as fatty acids, phosphoglycerol lipids, cholesteryl esters and glycerides. Remarkably, 13 CE lipid isomers were identified and simultaneously quantified from human plasma without requiring the use of lipid standards.
Strontium Leaching Precedes SrIrO3 Dissolution by a Wide Potential Gap During Electrochemical Water Oxidation

Published: April 2022

Mechanistic studies of oxide electrocatalysts for heterogeneous water oxidation have been primarily focused on understanding the origins of activity, with fewer studies studying fundamental properties influencing stability. The main challenge is directly observing and quantifying local structural instability under operating conditions. In this work, we study the degradation pathways of SrIrO3, a highly active electrocatalyst, during the oxygen evolution reaction (OER). This material serves as a model system for degradation studies of perovskite AMO3 oxides, exhibiting both A-cation leaching and transition metal (M) dissolution. Using operando electrochemical atomic force microscopy (EC-AFM), we track the potential-dependent Sr leaching and perovskite dissolution at the nanometer scale. We observe Sr leaching preceding perovskite dissolution by up to 0.8 V with a Sr leaching rate controlled by electrolyte composition. Ultimately, our study demonstrates the overall stability of perovskite oxides during electrocatalysis can be substantially improved by suppressing A-site leaching.

Published: April 2022

Background: UNICEF stated that in 2014, about 66% of children aged less than five years in lower-middle-income countries were stunted. Stunting is a predictor of poor quality of human resources and reduces a nation's productivity in the future. Stunting control in the Kulonprogo District is one of the priority districts in Indonesia. This study aimed to analyze the determinants of stunting in the Kulonprogo District.
Methods: This research was conducted in Kuponprogo District. The population was children under five in Kulonprogo District. Analysis was done through a descriptive approach. Descriptive quantitative research was used by employing secondary data from the year 2013.
Results: The prevalence of stunting among children under five in the Kulonprogo District was 11.12%, spread across all primary health centers (Puskesmas) in the Kulonprogo District. The three puskesmas with the highest prevalence rate were Puskesmas Girimulyo 2, Puskesmas Samigaluh 2, and Puskesmas Kalibawang. The analysis found that low-income families, maternal education, age at pregnancy, chronic energy deficiency during pregnancy, anemia during pregnancy, early initiation of breastfeeding, exclusive breastfeeding, and parenting mode are the determinant factors of stunting in the Kulonprogo District in 2019.
Conclusion: Several determinants of stunting were found, namely low-income families, maternal education, age at pregnancy, chronic energy deficiency during pregnancy, anemia during pregnancy, early initiation of breastfeeding, exclusive breastfeeding, and parenting mode.

Authors: Mukhopadhyay Amita , Debata Ipsita , Kamate Ravikiran P , Nagendra Nagaiah , Rodrigues Priyanka
Published: April 2022

Background: Milk promotes child growth; however, adulterated milk reduces nutritional value and exposes children to harmful chemicals. Therefore, this study aimed to assess the nutritional status of children aged 1â€“5 years living in the selected study area and test milk samples from the children's households for common adulterants. The study further aimed to explore the association between malnutrition and milk adulteration.Methods: We used a community-based cross-sectional study design conducted in the service area of a tertiary healthcare institute in Bangalore Rural District, Karnataka state, India. Systematic random sampling was used to recruit 180 children aged 1â€“5 years. Primary data was collected through interviews, anthropometry, and strip tests for milk adulteration. Statistical analysis consisted of descriptive analysis, Chi-square tests, odds ratios, and 95% confidence intervals.Results: Prevalence of underweight, stunting, wasting, and low Body Mass Index (BMI) was 13.33%, 38.33%, 15.0%, and 26.7%, respectively. General adulterants detected were neutralizers in 97 (53.9%) and maltodextrin in 90 (50%) samples. Higher proportions of stunting, underweight and low BMI were found in children drinking adulterated milk. Low BMI was significantly associated with joint family and lower maternal education.Conclusion: Our study found a high prevalence of malnutrition in children, particularly stunting. The study also detected widespread adulterants in milk and a potential association with malnutrition. The authors recommend further studies with a larger sample size to accurately delineate the relationship between milk adulteration and malnutrition.

Potential alternative natural colourant from Dendrobium Sonia ‘Earsakul’
Authors: Netramai S. , Kijchavengkul T. , Samsudin H. , Lertsiri S.
Published: April 2022

This study aimed to investigate optical properties, colour-changing characteristics, and
storage stability of crude aqueous extract of fresh Dendrobium Sonia ‘Earsakul’ (DSE)
orchid flower obtained through microwave-assisted extraction. IR spectra of the extract at
various pH indicated that anthocyanins were major pigments present in the crude extract.
As the pH of the extract increased from 2 to 11, its colour turned from reddish-orange to
magenta to purple to blue to green. Crude extract of DSE could be prepared in advance
and used within 2 weeks after preparation (if kept at 4°C) without significant reduction of
anthocyanin levels (P<0.05). The findings showed that DSE had the potential to be
utilized as a natural food colourant as an alternative for those from plants containing
cyanidin as the major anthocyanin, due to their similarities in colour-changing patterns
and high storage stability.
Changes in the Hydrodynamic Characteristics of Ships During Port Maneuvers
Authors: Mai Thi Loan , Vo Anh Khoa , Jeon Myungjun , Yoon Hyeon Kyu
Published: April 2022

To reach a port, a ship must pass through a shallow water zone where seabed effects alter the hydrodynamics acting on the ship. This study examined the maneuvering characteristics of an autonomous surface ship at 3-DOF (Degree of freedom) motion in deep water and shallow water based on the in-port speed of 1.54 m/s. The CFD (Computational fluid dynamics) method was used as a specialized tool in naval hydrodynamics based on the RANS (Reynolds-averaged Navier-Stoke) solver for maneuvering prediction. A virtual captive model test in CFD with various constrained motions, such as static drift, circular motion, and combined circular motion with drift, was performed to determine the hydrodynamic forces and moments of the ship. In addition, a model test was performed in a square tank for a static drift test in deep water to verify the accuracy of the CFD method by comparing the hydrodynamic forces and moments. The results showed changes in hydrodynamic forces and moments in deep and shallow water, with the latter increasing dramatically in very shallow water. The velocity fields demonstrated an increasing change in velocity as water became shallower. The least-squares method was applied to obtain the hydrodynamic coefficients by distinguishing a linear and non-linear model of the hydrodynamic force models. The course stability, maneuverability, and collision avoidance ability were evaluated from the estimated hydrodynamic coefficients. The hydrodynamic characteristics showed that the course stability improved in extremely shallow water. The maneuverability was satisfied with IMO (2002) except for extremely shallow water, and collision avoidance ability was a good performance in deep and shallow water.

A Study On Octane Requirement For Motor Vehicles In Indonesia
Authors: Kaslan F. Batti W
Published: April 2022

The knowledge of the exact level of octane number required for the car population in a country is quite important both for the petroleum refiners and the consumers. If the actual gasoline octane number is too high, the use of a superfu- ous anti-knock represents a loss for the refiners; on the contrary, if the octane level is too low, knock will result and risks of engine damage may occur. Various factors affecting the octane requirement of the car such as engine design, atmospheric conditions, service life of the car are reviewed. The octane level needed could only be assessed by actual measurements on cars representing the various type of cars in the country. Two consecutive studies for the requirement of the car population in Indonesia were carried out in 1978 and 1982 respectively, are described, and the results of the measurements of both studies are expressed octane requirement curves.

Laporan Kasus : Kombinasi Akupunktur Tubuh Dan Akupunktur Daun Telinga dalam Penanganan Nyeri akibat Dismenorea Primer
Authors: Ayu Permata Sari  , Irma Nareswari  , Didi Lazuardi
Published: April 2022

Latar belakang : Dismenorea primer (PDM) adalah nyerihaid yang terjadi tanpa adanya kelainan dari organ reproduksisecara nyata, yang timbul sejak menstruasi pertama dan terjadi biasanya dalam 6-12 bulan pertama setelah menarche. PDM berhubungan dengan kontraksi uterus yang dipicu oleh berkurangnya progesteron di awal menstruasi. Kontraksi inimenyebabkan iskemia uterus, yang akan memodulasi nyeriditambah dengan meningkatnya kadar prostaglandin. Akupunktur adalah salah satu modalitas terapi yang seringdigunakan untuk mengatasi nyeri, termasuk nyeri menstruasi. Akupunktur terbukti mengurangi nyeri secara efektif denganefek samping minimal sehingga dapat meningkatkan kualitashidup pasien.

Kasus : seorang perempuan 26 tahun dengan dismenoreaprimer yang sudah terjadi sejak beberapa tahun terakhir dan semakin lama keluhan nyeri semakin memberat (NRS 6), hingga saat terjadi dismenorea menggangu pekerjaan dan kualitas hidup pasien. Dilakukan terapi akupunktur sebanyak3 siklus menstruasi pada titik LI4 Hegu, SP10 Xuehai, sertatitik Kidney daun telinga bilateral. Elektroakupunkturgelombang DD 4/20 Hz diberikan pada titik CV4 Guanyuan, CV6 Qihai, SP9 Yinlingquan, SP8 Diji, SP6 Sanyinjiao dan ST36 Zusanli, sebanyak 2 kali seminggu, selama 20 menit per sesi.

Hasil : setelah 18 kai sesi akupunktur, skala nyeri pasien yang diukur dengan NRS berkurang dan kualitas hidup pasien yang diukur menggunakan kuesioner SF-36 hasilnya meningkat. Dalam follow up 3 bulan berikutnya setelah sesi akupunkturselesai, didapatkan bahwa saat menstruasi pasien hanyamengalami sedikit rasa tidak nyaman (NRS 1), tapi tidakmengalami nyeri seperti sebelum diterapi akupunktur. Sehingga akupunktur dapat berperan dalam penanganandismenorea primer, baik sebagai preventif maupun kuratif.

Published: April 2022

The study evaluated the economic analysis of cassava production in Akoko area of Ondo State, Nigeria. Data were collected using a well-structured questionnaire and interview schedule. Descriptive statistics, budgetary techniques and multiple regression model were employed for the data analysis. The results showed that the majority (72.7%) of cassava farmers were male households and they were within the active age group given a mean of 50years with a mean household size of 5 persons. About 80.7% of the farmers were married and had an average farming experience of 13years while about 82.0% of them had formal education. The cassava farmers had an average farm size of 1.9ha and many (62.7%) of them started their farming business with their personal income. The results of budgetary analysis revealed that the net farm income was ₦149,101.92 with the return on investment of ₦1.5. This implies that for every N1 invested in the business, there is a return of 50k. The result of the multiple linear regression showed that agrochemical, labour, farm input, and age were the major factors that had a significant influence on the profit of the cassava farmers. Again, inadequate capital for start-up, unstable price, and high cost of inputs were the main constraints faced by the farmers in the area. From the findings, there is a need for the cassava farmers in the study area to form a cassava farmer corporative to solve problems of accessibility to loan, resource allocation, dissemination of information and other challenges as this will increase their productivity and output.

Globalization cannot be separated from corporations. The development of the corporation through its products has been able to "bewitch" various areas of people's lives, and even the development of the corporation has also given birth to new forms of crime, namely corporate crime. To the development of corporate crime, national law has responded by harmonizing the subject of criminal law. As a result, corporations are included as subjects of criminal law whose arrangements are contained in legislation outside the Criminal Code. Construction of corporate criminal responsibility in legislation outside the Criminal Code, namely the maker can be convicted if he has committed a criminal act as formulated in the law, regardless of how his inner attitude (strict liability) and the imposition of responsibility on someone for actions committed by people other, solely based on the relationship between the two people (vicarious liability).

Eksistensi Republik Maluku Selatan sebagai Subjek Hukum Internasional: Antara Legitimasi dan Legalitas
Authors: Darnela Lindra
Published: April 2022

The Republic of South Maluku (RMS) at the beginning of its birth in the 1950s gained a place in international law as a group that has the right of self-determination by proclaiming itself as an independent Republic. Their presence became more apparent when those who were former KNIL members chose to temporarily move to the Netherlands and freely raised the RMS flag in the country. This paper discusses the existence of the Republic of South Maluku in international law recently, based on the perspective of legitimacy and legalization. This study used the interview method with several RMS figures, RMS descendants and some researchers on RMS. This research found that RMS currently no longer has legitimacy either in the Netherlands or in the Moluccas. This is supported by the lack of movement and support for the current RMS in Maluku and the existence of the RMS in the Netherlands at present only as their negotiations against the Dutch government as a minority group. Besides, in international law RMS is not a legal subject because it is no longer in the Belligerent category and is recognized by countries.Keywords: Republic of South Maluku (RMS), legitimacy, legality, international law

Typhoid fever is an infection caused by the bacterium Salmonella typhi, spread through contaminated food or water. Typhoid fever can be treated with antibiotics, but at this time some pathogen microbes have been resistant to the available antibiotics. Antimicrobials derived from natural product might be the alternative to overcome antibiotic resistance. Eleutherine palmifolia (L.) Merr is empirically used to treat infectious diseases. E. palmifolia has chemical compounds of alkaloids, glycosides, flavonoids, phenolics, steroids, and tannins. This study aims to evaluate the antibacterial activity of ethyl acetate fraction against S. typhi. E. palmifolia bulbs were subsequently extracted using n-hexane solvents and followed by ethyl acetate solvents. The ethyl acetate fraction was tested for antibacterial activity using the disc diffusion method. The ethyl acetate fraction of E. palmifolia at the concentrations of 8, 6, and 8 mg/paper disc showed the diameters of the inhibition zone of 15.1±3.6, 15.3±3.3, and 16.9±1.9 mm, respectively. The conclusion of this study was the ethyl acetate fraction of E. palmifolia has a strong antibacterial activity against S. typhi.
