Published: August 2021

AbstractThe use of manganese triacetate as an oxidant component in the C-4 arylations of 2-aryl-quinazoline 3-oxides with arylboronic acids­ is reported. The new protocol was applied to prepare new 2,4-di­arylated quinazoline 3-oxides in good to high yields. The method was shown to tolerate various substituents on both aromatic rings, and no complications such as deoxygenation or rearrangement to quinazolin-4(3H)-one was observed.

Published: August 2021

AbstractThe Scholl reaction of ortho-phenylene-bridged cyclic pyrrole-thiophene hybrid hexamer gave cyclophane-type [5]heterohelicene exclusively in 45% yield. The structure was unambiguously revealed by X-ray diffraction analysis. This helicenophane-type compound showed sharp absorption and fluorescence spectra, reflecting its rigid structure. The reaction path was analyzed on the basis of DFT calculations, and it was found that the formation of the [5]helicene-dimer is thermodynamically favored and further oxidation is prohibited due to the increased strain energy.
The Renaissance of Alkali Metabisulfites as SO2 Surrogates
Authors: Patel Bhisma K. , Sahoo Ashish Kumar , Dahiya Anjali , Rakshit Amitava 
Published: August 2021

AbstractThe upsurge of interest in the development of methodologies for the construction of sulfur-containing compounds via the use of expedient reagents has established sustainable tools in organic chemistry. This review focuses on sulfonylation reactions using inorganic sulfites (Na2S2O5 or K2S2O5) as the sulfur dioxide surrogates. Compared to the bis-adduct with DABCO, which is an excellent surrogate of gaseous SO2, the use of sodium or potassium metabisulfites as SO2 surrogates are equally efficient. The objective of the current review is to exemplify recent sulfonylation reactions using inorganic sulfites. For better understanding, the review is categorized according to the mode of reactions: transition-metal-catalyzed SO2 insertion, metal-free SO2 insertion, and visible-light-mediated SO2 insertion. All the reactions in each of the sections are illustrated with selected examples with a pertinent explanation of the proposed mechanism.1	Introduction2	Outlines of the Reactions Involving SO2 Insertion2.1	Transition-Metal-Catalyzed SO2 Insertion2.2	Transition-Metal-Free SO2 Insertion2.3	Visible-Light-Mediated SO2 Insertion3	Conclusion and Outlook
Synthesis and Reactions of 1,3,5-Tri- and 1,3,5,7-Tetracarbonyl Compounds
Authors: Langer Peter 
Published: August 2021

AbstractThe reaction of 1,3-bis(silyloxy)-1,3-butadienes with functionalized and nonfunctionalized acid chlorides and bis(acid chlorides) gives rise to the formation of a great variety of 1,3,5-tri- and 1,3,5,7-tetracarbonyl compounds and cyclic products derived from them. Examples include functionalized and nonfunctionalized 3,5-dioxopentanoates, 3,5-dioxopimelates, 3-alkylidene-3H-isobenzofuran-1-ones, salicylates, 3(2H)furanones, and 3-oxo-4-sulfonylesters. Methylation and cyclopropanation reactions of 1,3,5-tri- and 1,3,5,7-tetracarbonyl compounds do not provide access to the expected permethylated and cyclopropanated polycarbonyl compounds. However, the latter could be prepared by stepwise protocols. The reaction of 1,3,5-tri- and 1,3,5,7-tetracarbonyl compounds with dinucleophiles resulted in cyclization reactions to give a variety of heterocyclic structures.1 Introduction2 Reactions of 1,3-Bis(silyloxy)-1,3-butadienes with Acid Chlorides3 Reactions of 1,3,5-Tri- and 1,3,5,7-Tetracarbonyl Compounds4 Conclusion
Childhood Varicose Veins–An Unusual Visceral “May–Thurner” Like Compression

Published: August 2021

AbstractWe report the case of 8-year-old girl with left lower limb edema due to superficial venous incompetence and varicosities. Color Doppler demonstrated compression of the left common iliac vein by an ectopic left kidney, which was partly relieved in right lateral decubitus position. CT demonstrated ectopic malrotated pelvic kidney, compressing the left common iliac vein against the L5 vertebra. A “May–Thurner” like syndrome due to visceral compression needs to be suspected in children with unilateral left lower limb varicosities.

Published: August 2021

Abstract
Background Minimal access surgery is associated with improved cosmetic and other short-term outcomes. Conventionally, an abdominal incision is made for specimen extraction. We assessed the feasibility of specimen extraction through one of the natural orifices and analyzed its impact on short-term outcomes.
Methods A prospectively collected data were reviewed on consecutive patients who underwent natural orifice specimen extraction (NOSE) after laparoscopic colorectal surgery. The results were compared with a matched group who had transabdominal extraction (TAE) of the specimens. A systematic literature review was performed to compare our results.
Results The combined median operating time for right and left colectomies was significantly higher in the NOSE group as compared with TAE group (260 vs. 150). There was no mortality in either group and no conversions to TAE in the NOSE group. No local metastasis or major iatrogenic injuries were reported at the time of retrieval. The results were comparable to those of a meta-analysis of randomized controlled trials.
Conclusion The results of NOSE are comparable to those of TAEs. The absence of a minilaparotomy for specimen extraction may lead to a speedy recovery and better cosmesis.
The interplay between partisanship, forecasted COVID-19 deaths, and support for preventive policies
Authors: Freira Lucia , Sartorio Marco , Boruchowicz Cynthia , Lopez Boo Florencia , Navajas Joaquin 
Published: August 2021

AbstractThe COVID-19 pandemic is a global crisis that has forced governments around the world to implement large-scale interventions such as school closures and national lockdowns. Previous research has shown that partisanship plays a major role in explaining public attitudes towards these policies and beliefs about the intensity of the crisis. However, it remains unclear whether and how partisan differences in policy support relate to partisan gaps in beliefs about the number of deaths that the pandemic will cause. Do individuals who forecast fewer COVID-19 deaths show less agreement with preventive measures? How does partisanship correlate with people’s beliefs about the intensity of the crisis and their support for COVID-19 policies? Here, we sought to answer these questions by performing a behavioral experiment in Argentina (Experiment 1, N = 640) and three quasi-replication studies in Uruguay (Experiment 2, N = 372), Brazil (Experiment 3, N = 353) and the United States (Experiment 4, N = 630). In all settings, participants forecasted the number of COVID-19 deaths in their country after considering either a high or low number, and then rated their agreement with a series of interventions. This anchoring procedure, which experimentally induced a large variability in the forecasted number of deaths, did not modify policy preferences. Instead, each experiment provided evidence that partisanship was a key indicator of the optimism of forecasts and the degree of support for COVID-19 policies. Remarkably, we found that the number of forecasted deaths was robustly uncorrelated with participants’ agreement with preventive measures designed to prevent those deaths. We discuss these empirical observations in the light of recently proposed theories of tribal partisan behavior. Moreover, we argue that these results may inform policy making as they suggest that even the most effective communication strategy focused on alerting the public about the severity of the pandemic would probably not translate into greater support for COVID-19 preventive measures.
Machine learning to accelerate screening for Marcus reorganization energies
Authors: Abarbanel Omri D. , Hutchison Geoffrey R. 
Published: August 2021

Understanding and predicting the charge transport properties of π-conjugated materials is an important challenge for designing new organic electronic devices, such as solar cells, plastic transistors, light-emitting devices, and chemical sensors. A key component of the hopping mechanism of charge transfer in these materials is the Marcus reorganization energy which serves as an activation barrier to hole or electron transfer. While modern density functional methods have proven to accurately predict trends in intramolecular reorganization energy, such calculations are computationally expensive. In this work, we outline active machine learning methods to predict computed intramolecular reorganization energies of a wide range of polythiophenes and their use toward screening new compounds with low internal reorganization energies. Our models have an overall root mean square error (RMSE) of ±0.113 eV, but a much smaller RMSE of only ±0.036 eV on the new screening set. Since the larger error derives from high-reorganization energy compounds, the new method is highly effective to screen for compounds with potentially efficient charge transport parameters.
“What I advise you to do is…”
Authors: El-Dakhs Dina Abdel Salam , Ahmed Mervat M. 
Published: August 2021

Abstract
The current study aims to examine the realization of the speech act of advising among Egyptian university
teachers. To this end, 50 Egyptian university teachers at a private university completed eight role-plays in which they gave
solicited advice to their fellow teachers. The role-plays were recorded and later transcribed. The data were coded for the
advising strategies as well as the initiators and internal/external modifiers. The results showed the participants’ preference for
the use of direct advising. The results also showed a minimal influence for the advisor’s gender and years of teaching experience
on the participants’ advising preferences. A major influence, however, was observed for the variable of social dominance as
represented in the advisee’s academic rank. The results are interpreted in terms of the Mixed Game Model and earlier studies on
the speech act of advising.
Constructing disagreement space
Authors: Vasilyeva Alena L. 
Published: August 2021

Abstract
The study is a single case analysis and explores how disagreement space is constructed in a dialogue that
addresses language ideology and identity issues in Belarus. Disagreement space is understood as a set of the interactant’s
commitments, beliefs, intentions that can be reconstructed from their actions and “called out” by another participant (Jackson 1992). The interactional data includes the video-recording of the debate that was
devoted to the issue whether Belarusian should be the only official language of Belarus. While two opponents are dominating
parties in this debate, the host also plays an important role in this argumentative activity. The current study examines the
host’s actions to shape disagreement space and argues that the host should be viewed as a valid party in a multi-party
argumentative activity.

Environmental impacts and resource use of urban agriculture: a systematic review and meta-analysis
Authors: Dorr Erica , Goldstein Benjamin , Horvath Arpad , Aubry Christine , Gabrielle Benoit 
Published: August 2021

Abstract
Environmental merits are a common motivation for many urban agriculture (UA) projects. One powerful way of quantifying environmental impacts is with life cycle assessment (LCA): a method that estimates the environmental impacts of producing, using, and disposing of a good. LCAs of UA have proliferated in recent years, evaluating a diverse range of UA systems and generating mixed conclusions about their environmental performance. To clarify the varied literature, we performed a systematic review of LCAs of UA to answer the following questions: What is the scope of available LCAs of UA (geographic, crop choice, system type)? What is the environmental performance and resource intensity of diverse forms of UA? How have these LCAs been done, and does the quality and consistency allow the evidence to support decision making? We searched for original, peer-reviewed LCAs of agricultural production at UA systems, and selected and evaluated 47 papers fitting our analysis criteria, covering 88 different farms and 259 production systems. Focusing on yield, water consumption, greenhouse gas emissions, and cumulative energy demand, using functional units based on mass of crops grown and land occupied, we found a wide range of results. We summarized baseline ranges, identified trends across UA profiles, and highlighted the most impactful parts of different systems. There were examples of all types of systems—across physical set up, crop type, and socio-economic orientation—achieving low and high impacts and yields, and performing better or worse than conventional agriculture. However, issues with the quality and consistency of the LCAs, the use of conventional agriculture data in UA settings, and the high variability in their results prevented us from drawing definitive conclusions about the environmental impacts and resource use of UA. We provided guidelines for improving LCAs of UA, and make a strong case that more research on this topic is necessary to improve our understanding of the environmental impacts and benefits of UA.

Abstract
The approach of the paper is to present a review of solar power generation, utilization and its management for facilitating sustainable development in India. It briefs about the allusive estimation of the solar energy and its utilization. The Solar Energy is a gigantic energy source that can be used for any of the day-to-day requirements, including engineering, the refrigeration, the water heating, the heat of industrial processes, transportation and sustainable production and even for the cleaning of environment. The solar radiation is the purest and cleanest form of the energy where no mass is attached, and it can be converted in to any forms easily. The solar energy that falls on the surface of the earth is sufficient to provide solution to all our requirements on this planet. Among all the sectors of India, power sector is largest one which is important for the growth of Indian economy. There is perpetual and rising demand of power in the all the sectors. So, to meet the increasing demand and to overcome the shortage of power, generation of power by renewable energy source is must for sustainability in this field. In the today’s scenario, generation of power from renewable energy source is necessary as compared to non-renewable energy sources. This paper emphasizes on the the scope of generation, usage and its management for sustainable development of India.

Authors: Hatti Prashant S. , Somanakatti Anupama B. , Rakshith M 
Published: August 2021

Abstract
Prosthesis is an artificial substitute for body parts such as limbs, eye, tooth, etc. Generally, the prosthesis is referred to as a fabricated substitute used to assist the damaged part of the body. The devices are made up of light materials like plastics, aluminium, and composites materials. The prosthetic technology is aimed to replicate the body part which is damaged irreversibly due to unfortunate incidents. The present work deals with creation of an optimized design for the prosthetic leg proposed by Saito et al. [2]. The material of prosthetic leg proposed here is made up of Carbon Fiber Reinforced Polymer (CFRP) composite laminate, having unidirectional and cross-ply stacking sequence, which is analyzed for static stress and failure loads. From the results, it is evident that, while a uni-directional laminate can withstand a failure load of 4910 N, a cross-ply laminate withstands 4282 N. Also, the individual ply versus stress is studied in this work.

The effects of saccharin on the electrodeposition of NiCoFe films on a flexible substrate
Authors: Budi Setia , Manaf Azwar 
Published: August 2021

AbstractIn this work, the influence of saccharin on the electrodeposition of NiCoFe film on a flexible substrate was investigated. NiCoFe electrodeposition was carried out at different potentials from electrolytes both with and without saccharin. The addition of saccharin modified the nuclei growth mechanism, making the growth phase slower than that in the saccharin-free electrolyte. Ohm’s law suggested that the two electrolytes differed in their resistance values. The presence of saccharin increased the current efficiency of NiCoFe electrodeposition at all co-deposition potentials and slightly enhanced the deposition rate due to the inhibition of hydrogen evolution during the reaction. The addition of saccharin also significantly decreased the anomalous co-deposition of NiCoFe compared to that which took place in the saccharin-free system. This approach successfully grew the crystalline phase of NiCoFe films on indium tin oxide-coated flexible polyethylene terephthalate substrate by varying the applied co-deposition potential, which controlled the chemical composition of the films.
Using satellite data to assess management frequency and rate of regeneration on heather moorlands in England as a resilience indicator
Authors: Lees K J , Buxton J , Boulton C A , Abrams J F , Lenton T M 
Published: August 2021

Abstract
Peatland resilience, defined here as the rate of recovery from perturbation, is crucial to our understanding of the impacts of climate change and land management on these unique ecosystems. Many peatland areas in the UK are managed as grouse moors using small burns (or increasingly, heather cutting) to encourage heather growth and limit fuel load. These small burns or cuts are distinct disturbance events which provide a useful means of assessing resilience. Until now, it has been difficult to monitor the area affected by management each season due to the remoteness and size of moorland sites. Newer satellite sensors such as those on Sentinel-2 are now collecting data at a spatial resolution that is fine enough to detect individual burns or cut areas, and at a temporal resolution which can be used to monitor occurrence and recovery each year. This study considered four areas of moorland; the North Pennines, Yorkshire Dales, North York Moors, and the Peak District. For each of these areas Sentinel-2 optical data was used to detect management areas using the dNBR (differenced Normalized Burn Ratio), and to monitor vegetation recovery using the NDVI (Normalised Difference Vegetation Index). Significant differences were found between the four selected sites in management repeat interval, with the North York Moors having the shortest repeat interval of 20 years on average (compared to 40–66 years across the other three study sites). Recovery times were found to be affected by burn size and severity, weather during the summer months, and altitude. This suggests that the interactions between peatland management and climate change may affect the future resilience of these areas, with hot, dry summers causing longer management recovery times.
Co-occurrence of m.15992A&gt;G and m.15077G&gt;A Is Associated With a High Penetrance of Maternally Inherited Hypertension in a Chinese Pedigree
Authors: Guo Hao , Guo Li , Yuan Yong , Liang Xin-yue , Bi Rui 
Published: August 2021

Abstract

BACKGROUND
Mitochondrial DNA (mtDNA) pathogenic variants have been identified to be associated with maternally inherited essential hypertension (MIEH). However, the distinctive clinical features and molecular pathogenesis of MIEH are not fully understood.

METHODS
In this study, we collected a Chinese MIEH family with extraordinary higher penetrance of essential hypertension (88.89%) and early ages of onset (31–40 years old), and performed clinical and genetic characterization for this family. The complete mitochondrial genome of the proband was sequenced and analyzed.

RESULTS
The maternally related members in this family were presented with severe increased blood pressure, left ventricular remodeling, and metabolic abnormalities. Through sequencing the entire mtDNA of the proband and performing systematic analysis of the mtDNA variants with a phylogenic approach, we identified a potentially pathogenic tRNA variant (m.15992A&gt;G in the MT-TP gene) that may account for the MIEH in this family. One nonsynonymous variant (m.15077G&gt;A in the MT-CYB gene) was identified to play a synergistic role with m.15992A&gt;G to cause a high penetrance of MIEH.

CONCLUSIONS
Our results, together with previous findings, have indicated that tRNA pathogenic variants in the mtDNA could act important roles in the pathogenesis of MIEH through reducing mitochondrial translation and disturbing mitochondrial function.
