Microwave-assisted Synthetic Scheme of Novel Schiff Base Congeners of
Pyrimidine Nuclei by Using Water as Solvent: A Green Approach to Synthesis
Authors: Kumar Dileep , Karati Dipanjan , Mahadik Kakasaheb Ramoo 
Published: April 2022

Aim:
The research work aims to develop a sustainable microwave-assisted scheme for the
synthesis of 4-(benzylidene amino)-6-phenylpyrimidine-5-carbonitrile congeners.

Background:
4-(benzylidene amino)-6-phenylpyrimidine-5-carbonitrile scaffolds are novel molecules
having various pharmacological activities, such as neurodegenerative, antimicrobial, and anticancer.
Schiff base congeners are considered efficient pharmacophores for research. These activities are due to
the presence of azomethine (CH=N) group in the Schiff base compounds.

Objectives:
The aim of the study was to synthesise different novel Schiff base scaffolds of pyrimidine
nuclei by green chemistry in good yield.

Methods:
The 4-(benzylidene amino)-6-phenylpyrimidine-5-carbonitrile scaffolds were prepared by
two-step reactions. Both steps were microwave-assisted. The first step was to synthesize 4-amino-6-
phenylpyrimidine-5-carbonitrile as an intermediate compound. This compound was synthesized by
using benzaldehyde, malononitrile and formamidine hydrochloride. The reaction conditions are as
follows: temperature- 101°C, pressure- 300W, time- 50min.
The final Schiff base congeners were obtained by reacting them with various aromatic aldehydes in the
second step. The yield, reaction condition, and time consumption were all very acceptable for the green
synthetic methods rather than the conventional schemes.

Results:
Microwave-assisted method was more efficient. The reactions were less time-consuming, and
the overall yield of the all-synthesized compounds was in the range of 72-81%. The synthesized congeners
were characterized by different spectroscopic methods. The main functional group, azomethine,
was considered by the IR peak at 1611 cm-1 wavelength.

Conclusions:
This microwave-assisted synthetic method thus emerges as more eco-friendly due to a
much-reduced usage of organic solvents, leading to less harmful residues. Using this scheme, we synthesized
different Schiff base congeners with satisfactory chemical yields.

Authors: Pace Thaddeus W W , Zeiders Katharine H , Cook Stephanie H , Sarsar Evelyn D , Hoyt Lindsay T , Mirin Nicholas L , Wood Erica P , Tatar Raquel , Davidson Richard J 
Published: April 2022

Background
Firefighters are often exposed to occupational stressors that can result in psychological distress (ie, anxiety and depression) and burnout. These occupational stressors have only intensified with the onset of the COVID-19 pandemic and will likely persist in the postpandemic world.

Objective
To address occupational stressors confronting firefighters, we pilot tested a novel, cost-effective, smartphone app–based meditation intervention created by Healthy Minds Innovations that focused on mindfulness (awareness) training along with practices designed to cultivate positive relationships (connection), insight into the nature of the self (insight), and a sense of purpose in the context of challenge (purpose) with a sample of professional firefighters from a large metropolitan area in southwestern United States.

Methods
A total of 35 participants were recruited from a closed online group listserv and completed the self-guided 10-unit meditation app over the course of 10 days, at 1 unit per day. We assessed anxiety symptoms, depression symptoms, burnout, and negative affect as well as saliva diurnal cortisol rhythm, an objective indicator of stress-related biology, before and after use of the meditation app.

Results
This study demonstrated the meditation app was both feasible and acceptable for use by the majority of firefighters. We also found significant reductions in firefighters’ anxiety (P=.01), burnout (P=.05), and negative affect (P=.04), as well as changes in cortisol diurnal rhythm, such as waking cortisol (P=.02), from before to after use of the meditation app.

Conclusions
Our study findings call for future research to demonstrate the efficacy of this meditation app to reduce psychological distress and burnout in firefighters.

Background
Digital health interventions have become increasingly common across health care, both before and during the COVID-19 pandemic. Health inequalities, particularly with respect to ethnicity, may not be considered in frameworks that address the implementation of digital health interventions. We considered frameworks to include any models, theories, or taxonomies that describe or predict implementation, uptake, and use of digital health interventions.

Objective
We aimed to assess how health inequalities are addressed in frameworks relevant to the implementation, uptake, and use of digital health interventions; health and ethnic inequalities; and interventions for cardiometabolic disease.

Methods
SCOPUS, PubMed, EMBASE, Google Scholar, and gray literature were searched to identify papers on frameworks relevant to the implementation, uptake, and use of digital health interventions; ethnically or culturally diverse populations and health inequalities; and interventions for cardiometabolic disease. We assessed the extent to which frameworks address health inequalities, specifically ethnic inequalities; explored how they were addressed; and developed recommendations for good practice.

Results
Of 58 relevant papers, 22 (38%) included frameworks that referred to health inequalities. Inequalities were conceptualized as society-level, system-level, intervention-level, and individual. Only 5 frameworks considered all levels. Three frameworks considered how digital health interventions might interact with or exacerbate existing health inequalities, and 3 considered the process of health technology implementation, uptake, and use and suggested opportunities to improve equity in digital health. When ethnicity was considered, it was often within the broader concepts of social determinants of health. Only 3 frameworks explicitly addressed ethnicity: one focused on culturally tailoring digital health interventions, and 2 were applied to management of cardiometabolic disease.

Conclusions
Existing frameworks evaluate implementation, uptake, and use of digital health interventions, but to consider factors related to ethnicity, it is necessary to look across frameworks. We have developed a visual guide of the key constructs across the 4 potential levels of action for digital health inequalities, which can be used to support future research and inform digital health policies.
Geodynamic model of the interaction between the continental lithosphere and the active continental margin in East Asia
Authors: Lobkovsky Leopold , Gabsatarov Yu. , Alekseev Dmitry , Vladimirova Irina , Ramazanov M. , Kotelkin V. 
Published: April 2022

We propose a concept for a geodynamic model of East Asia, taking into account the mechanism of the
interaction between the stable part of the regional continental lithosphere and the active continental
margin along the Kuril-Kamchatka and Japan island arcs. The concept involves upper mantle
convection combined with keyboard-block mechanism explaining seismic cycle patterns in the active
continental margin and provides grounds to resolve the paradoxes of the present-day velocity field
observed by satellite geodesy methods. These paradoxes are associated with enormous variation in the
velocity field, such as sometimes contradict directions of surface motions in the adjacent portions of the
earth’s surface. We propose a model that attribute the observed motion pattern to the superposition of
the long-term subduction-driven convection regime beneath the continent causing the ocean-ward
lithosphere extension and the shorter-term cyclic motion of seismogenic blocks with alternating
directions. The model contributes to the development of the physically-based theoretical concepts of
modern plate tectonics and eliminates the contradictions between the observed data and classical plate
tectonics in East Asia region.

Published: April 2022

A fabrication of eco-friendly and low-cost adsorbent materials is reported for CO2 removal. Alginate nanofibers (NFs) adsorbents were prepared by incorporating poly(vinyl alcohol) (PVA) into alginate solutions via electrospinning technique from alginate biopolymers. Smooth-surfaced Alg/PVA NFs were obtained with a specific surface area of 9.197 m2 g–1. Zeolite (Z) was impregnated into polymer solutions to enhance the properties and performances of alginate nanofibers. Alg/PVA/Z NFs appeared to be rougher with a specific surface area of 25.998 m2 g–1. Both adsorbents offered great potential for CO2 adsorbent in the future. The adsorption isotherms of Alg/PVA NFs followed the Langmuir model with optimum CO2 adsorption capacity of 3.286 mmol g–1 and Alg/PVA/Z NFs followed Dubinin-Radushkevich model with optimum CO2 adsorption capacity of 10.710 mmol g–1.

Published: April 2022

Direct methanol fuel cell (DMFC) attracts much attention due to its high abundance, environmental friendliness, and convenient transportation and storage. In this study, a novel catalyst of Pt3Mo alloy nanoparticles (NPs) on non-carbon Ti0.8W0.2O2 support was synthesized by microwave-assisted polyol process. The characteristic of Pt3Mo NPS/Ti0.8W0.2O2 catalyst was determined by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electronic microscopy (SEM), energy-dispersive X-ray (EDX), and Brunauer-Emmett-Teller (BET) method. Pt3Mo NPs had an average diameter of approximate 5.18 nm and were uniformly anchored on Ti0.8W0.2O2 surface. The ratio of Mo in the Pt3Mo alloy was consistent with the theoretical value, which supported the effectiveness of the synthesis method. In addition, Pt3Mo/Ti0.8W0.2O2 electrocatalysts exhibited higher CO-like tolerance in methanol oxidation reaction (MOR) than commercial electrocatalysts, excellent catalytic activity, and strong durability after 2000 cycles. The synergistic effect of Pt-Mo alloy, and the strong interaction between the bimetallic Pt-Mo alloy and the mesoporous Ti0.8W0.2O2 support, could weaken the Pt-CO bond. Besides, the high corrosion resistance and superior electrochemical durability of TiO2-based oxide also contribute to the excellent stability of Pt3Mo/Ti0.8W0.2O2 electrocatalyst in harsh electrochemical media. These results revealed that this material could be a potential catalyst in DMFC technology.

Penelitian ini bertujuan untuk mengetahui proses pelaksanaan tradisi melengkan pada suku Gayo, perbedaan tradisi melengkan dahulu dan sekarang, dan yang melatar belakangi perubahan tradisi melengkan yang sekarang sudah jarang dilakukan oleh suku Gayo. Metode Penelitian ini menggunakan penelitian kualitatif dengan pendekatan deksriptif . Teknik pengumpulan data dilakukan melalui observasi, wawancara, dokumentasi dan studi pustaka. Teknik analisis data dilakukan dengan langkah antara lain, reduksi data, mendisplai data, dan penarikan kesimpulan. Hasil penelitian ini menggambarkan bahwa tradisi melengkan ini merupakan pidato adat dengan berbentuk puisi atau pantun yang disampaikan oleh dua orang pelaku pe-melengkan dengan berbalas-balasan, yang dilakukan oleh sarak opat, yaitu terdiri dari (reje, imem, petue, rakyat), yang merupakan empat unsur pemerintahan di gayo, tradisi melengkan ini dilakukan untuk mengingat dan mengenang asal-usul suku Gayo dengan pemaknaan yang baik dan dengan kata-kata halus dan lembut. Tradisi melengkan yang masih dilakukan oleh suku gayo pada saat upacara perkawinan, khitanan maupun upacara lainnya, namun saat ini tradisi melengkan sudah jarang dilakukan oleh suku Gayo itu sendiri. Dikarenakan banyak suku Gayo yang tidak pandai melakukan tradisi melengkan dan sudah tidak mengerti nilai dan makna dari tradisi melengkan tersebut, sehingga tradisi melengkan pun sudah jarang dilakukan oleh suku Gayo.
