Published: January 2021

BackgroundEmotion plays an important role in mental health. Studying the relationship between emotion and mental health requires effective emotion-eliciting materials. Most standardized emotional stimuli, however, were based on Western contents and have not been validated in other cultures. The present study compared the emotional response to standard Western videos with videos of Chinese contents in a large representative Chinese sample. The effects of content source (film vs. real-life) and delivery medium (online vs. offline), as well as the effects of demographic factors were investigated. Participants’ depression level was assessed to test the potential use of the videos in mental health research.MethodsTop-ranked videos of basic emotions commonly implicated in mental health (happiness, sadness, anger, and fear) were chosen from a widely used Western video database. Twelve corresponding Chinese videos (film or real-life) were selected, with three clips for each emotion. In addition, three Chinese videos of the emotion “awe” were included because of the growing research attention to its role in promoting mental health. A large representative sample were recruited (N = 348) either online or offline and each participant viewed and rated his/her emotional reaction to all videos.ResultsAll Chinese and Western videos effectively elicited target emotions. The intensity of emotional response was generally higher for Chinese videos than for Western videos. Film and real-life videos provided mixed results in terms of the intensity of elicited emotions. There was a small difference in the delivery medium in which one video watched online were rated more intense than being watched in the laboratory. Older adults were more emotional reactive than young people in general, but the latter showed more differentiated response to Chinese versus Western videos. People with higher education levels responded less to happy videos. Finally, emotional reactivity of anger and awe were negatively related to depression level, which was partially consistent with the emotional-context-insensitivity (ECI) hypothesis of depression.ConclusionsThe results suggest that both Western and Chinese videos could reliably elicit emotion in Chinese people, but videos with local contents were generally more effective. The set of videos can be a useful tool for studying emotion and mental health in the Chinese cultural context.

Background
Facial fracture is one of the most common injuries globally. Some types of facial fractures may cause irreversible damage and can be life-threatening. This study aimed to investigate the health burden of facial fractures at the global, regional, and national levels from 1990 to 2017.

Methods
Facial fracture data, including the incidence, prevalence, and years lived with disability (YLDs) from 1990 to 2017, were obtained from the Global Burden of Disease study. We calculated the estimated annual percentage changes (EAPCs) to assess the changes of facial fractures in 195 countries or territories and 21 regions.

Results
From 1990 to 2017, the change in cases of facial fracture incidence was 39% globally, while the age-standardized incidence rate showed a downtrend with an EAPC of 0.00. Syria experienced a ten-fold increase in incidence cases with an EAPC of 9.2, and this condition is largely responsible for the global health burden of facial fractures. The prevalence and YLDs showed a similar trend worldwide as the incidence. Additionally, we found that the incidence, prevalence, and YLDs showed a discrepancy among various age groups with a gradual change of proportion over the past 28 years. The age-standardized rates (ASRs) of facial fractures were nearly twice for male than those for female from 1990 to 2017.

Conclusions
EAPC showed a correlation with the ASRs of facial fractures and had no relationship with socio-demographic index. The proportion of children and elderly suffering from facial fractures slightly changed with time. The ratio of facial fractures between males and females was 2:1. These findings suggest that more targeted and specific strategies based on age and gender should be established in various countries and regions.

Published: January 2021

Precise irrigation plays an essential role in agricultural production and its management. Based on current conditions and historical records, profitability in the farming sector depends on making the right and timely operational decision. For the last two decades, especially in India, climate change, groundwater depletion, and erratic variation in rainfall have affected crop production significantly. Due to advancements in technologies and reduction in size, sensors are becoming involved in almost every field of life. Agriculture is one such domain where sensors and their networks are successfully used to get numerous benefits from them. In this paper, a review of the scope of smart irrigation using IoT has been discussed. The scarcity of agricultural workers in irrigation can be compensated by the Internet of Things (IoT) platform. The various parameters, such as soil moisture, soil temperature, humidity, and pH, have been collected using the Internet of Things (IoT) platform, equipped with sensors and wireless communication systems (WSN).

Published: January 2021

Aims: This study investigated the use of agro-wastes for the production of briquettes. It was carried out to investigate the effect of formulation, binder and compaction pressure of rice husk-Bagasse briquettes on thermal and physical properties.
Study Design: The experimental design for this study was 6x5x2 Randomized Complete Block Design
Place and Duration of the Study: Rice husks and bagasse were collected from Lake Basin Development Authority’s rice mill and Kibos sugar and Allied company respectively. The binders were sourced locally in Kisumu. The study was conducted between March 2019 and February 2020. The fabrication and laboratory analysis were carried out in the engineering and laboratory departments of Kenya Industrial Research and Development institute, Kisumu.
Methodology: The experimental design for this study was 6x5x2 Randomized Complete Block Design. This study involved six formulations ratios (0:100, 20:80, 40:60, 60:40, 80:20, 100:0), five compaction pressure levels (108kPa, 180kPa, 253kPa, 325kPa, 397kPa) and two binders (clay, cassava) They were arranged in Randomize Complete Block Design with three replications per experiment.
Results: The briquettes bulk density was in the range of 849 to 1001 kg.m−3, while the calorific value ranged from 5.541 kcal/g for 100% Rice husk clay binder to 7.345 kcal/g 20% Rice Husk cassava binder. Briquettes with blend ratio of 40-60% Rice Husk took longer time to burn. Briquette formulations with clay binder had burning rates ranging from 0.28 g/min to 0.15 g/min while with cassava binder from 0.52 g/min to 0.37 g/min. The ignition time of the briquettes ranged from 62 sec to 95 sec with cassava binder and 110 sec to 191sec with clay binder. The shatter index ranged from 0.94 to 0.99 with cassava and 0.9 to 0.98 with clay binder.
Conclusion: Higher compaction pressures and use of cassava binder produced stronger briquettes with higher calorific values. Briquettes with higher percentage of bagasse had low ignition time and low bulk densities. The bulk densities and ignition time showed significant rise with increase in the compaction pressure but inversely affected the burning rate. The binder used significantly affected both the thermal and physical properties of all the formulations.

Abstract

Introduction
Emergency physicians frequently provide care for patients who are experiencing viral illnesses and may be asked to provide verification of the patient’s illness (a sick note) for time missed from work. Exclusion from work can be a powerful public health measure during epidemics; both legislation and physician advice contribute to patients’ decisions to recover at home.

Methods
We surveyed Canadian Association of Emergency Physicians members to determine what impacts sick notes have on patients and the system, the duration of time off work that physicians recommend, and what training and policies are in place to help providers. Descriptive statistics from the survey are reported.

Results
A total of 182 of 1524 physicians responded to the survey; 51.1% practice in Ontario. 76.4% of physicians write at least one sick note per day, with 4.2% writing 5 or more sick notes per day. Thirteen percentage of physicians charge for a sick note (mean cost $22.50). Patients advised to stay home for a median of 4 days with influenza and 2 days with gastroenteritis and upper respiratory tract infections. 82.8% of physicians believe that most of the time, patients can determine when to return to work. Advice varied widely between respondents. 61% of respondents were unfamiliar with sick leave legislation in their province and only 2% had received formal training about illness verification.

Conclusions
Providing sick notes is a common practice of Canadian Emergency Physicians; return-to-work guidance is variable. Improved physician education about public health recommendations and provincial legislation may strengthen physician advice to patients.

ObjectiveTo evaluate heterogeneity of treatment effects in a trial of exercise‐based interventions for knee osteoarthritis (OA).MethodsParticipants (n = 350) were randomized to standard physical therapy (PT; n = 140), internet‐based exercise training (IBET; n = 142), or wait list (WL; n = 68) control. We applied qualitative interaction trees (QUINT), a sequential partitioning method, and generalized unbiased interaction detection and estimation (GUIDE), a regression tree approach, to identify subgroups with greater improvements in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score over 4 months. Predictors included 24 demographic, clinical, and psychosocial characteristics. We conducted internal validation to estimate optimism (bias) in the range of mean outcome differences among arms.ResultsBoth QUINT and GUIDE indicated that for participants with lower body mass index (BMI), IBET was better than PT (improvements of WOMAC ranged from 6.3 to 9.1 points lower), and for those with higher BMI and a longer duration of knee OA, PT was better than IBET (WOMAC improvement was 6.3 points). In GUIDE analyses comparing PT or IBET to WL, participants not employed had improvements in WOMAC ranging from 1.8 to 6.8 points lower with PT or IBT versus WL. From internal validation, there were large corrections to the mean outcome differences among arms; however, after correction, some differences remained in the clinically meaningful range.ConclusionResults suggest there may be subgroups who experience greater improvement in symptoms from PT or IBET, and this finding could guide referrals and future trials. However, uncertainty persists for specific treatment‐effects size estimates and how they apply beyond this study sample.
Corn and soybean yields and returns are greater in rotations with wheat

Published: January 2021

AbstractSimple rotations containing only corn (Zea mays L.) and/or soybean (Glycine max L.) dominate landscapes despite agronomic, soil health, and environmental benefits associated with diversification. We hypothesize that inclusion of wheat (Triticum aestivum L.) in corn–soybean (CS) rotations increases yield and net returns and that this benefit is becoming larger over time. Yields from rotation–tillage trials located near Elora and Ridgetown, ON, Canada, respectively, were used to investigate the yield and return effects of diversifying CS rotation using wheat with/without red clover (Trifolium pratense L). At Elora, wheat inclusion increased rate of yield increase in corn and soybean over 36 yr. During the latter 16 yr, adding wheat to CS rotation increased conventional tillage (CT) 1st and 2nd‐year corn yields (with red clover) by 0.43 Mg ha−1 (4.2%) and 0.98 Mg ha−1 (11.8%), respectively, no‐till 1st and 2nd‐year corn yields (no red clover) by 0.78 Mg ha−1 (9.9%) and 0.45 Mg ha−1 (5.3%), respectively, and 1st‐year soybean yield by 0.34 Mg ha−1 (11.8%). At Elora, net returns in the 4‐yr wheat‐containing rotations were 10% greater compared to the CS rotation. Similar corn and soybean yield responses including wheat in 2 or 3 yr rotations also occurred at the greater‐yielding Ridgetown trial, however net returns were not increased relative to the CS rotation. Inclusion of wheat in CS rotation once every 4–5 yr may provide the optimal balance between accruing higher net returns from corn and soybean while minimizing direct net revenue reductions associated with wheat.

AimThis study assessed whether emergency abdominal surgeries were changed in the coronavirus disease (COVID‐19)‐affected environment at a community hospital in Japan, with the goal of planning and preparing hospital resources against the further spread of COVID‐19.MethodsA total of 179 patients who underwent emergency abdominal surgery over 4 months during the pandemic (1 March, 2020 to 30 June, 2020) and a control period (1 March, 2019 to 30 June, 2019) were enrolled in this retrospective study. Patient demographics, hospital visiting patterns (visit time, ambulance transport, and duration of symptom onset to hospital visit), severity of patients’ condition, and surgical characteristics were compared between the two periods.ResultsThe number of patients undergoing emergency abdominal surgery during the pandemic did not decrease in comparison to the control period (89 patients versus 90 patients). The duration of symptom onset to hospital visit during the pandemic was not prolonged compared to the control period. Other hospital visiting patterns, severity of patients’ condition, and surgical characteristics were also similar in both periods.ConclusionAlthough the situation of the pandemic was different between countries and regions, the number of emergency surgeries in our hospital remained unchanged, and those patients visited the emergency room no later than usual.
Übergangsmetallkomplexe als Katalysatoren für die elektrische Umwandlung von CO2 – eine metallorganische Perspektive

Published: January 2021

AbstractDie elektrokatalytische Umwandlung von Kohlendioxid ist in der CO2‐Nutzung seit langem von Interesse. Während sich viele Studien auf den direkten Elektronentransfer vom Elektrodenmaterial auf das CO2‐Molekül konzentrieren, bieten molekulare Übergangsmetallkomplexe in Lösung die Möglichkeit, als Katalysatoren für den Elektronentransfer zu wirken. C1‐Verbindungen wie Kohlenmonoxid, Formiat oder Methanol werden oft als Hauptprodukte angestrebt, aber auch kompliziertere Umwandlungen sind innerhalb der Koordinationssphäre des Metallzentrums möglich. Dieser Perspektivartikel behandelt ausgewählte Beispiele, um die gegenwärtig favorisierten Mechanismen für die elektrochemisch induzierten und durch homogene Übergangsmetallkomplexe geförderten Umwandlungspfade von CO2 zu illustrieren und zu kategorisieren. Diese Erkenntnisse werden mit den Konzepten und Elementarschritten der metallorganischen Katalyse untermauert, um mögliche Strategien zur Erweiterung der molekularen Produktvielfalt als Zukunftsperspektive abzuleiten.
Vapochromic Behaviors of A Solid‐State Supramolecular Polymer Based on Exo‐Wall Complexation of Perethylated Pillar[5]arene with 1,2,4,5‐Tetracyanobenzene

Published: January 2021

AbstractThe research for the solid‐state supramolecular polymers with specific functions accelerates the development of supramolecular and materials sciences. Herein, we discover the different complexation modes of perethylated pillar[5]arene (EtP5) with 1,2,4,5‐tetracyanobenzene (TCNB) in various solvents. Driven by charge‐transfer interaction, TCNB is enclosed in the cavity of EtP5 in CHCl3, while TCNB complexes with EtP5 at the exo‐wall of EtP5 in CH2Cl2. This is because the size of CH2Cl2 matches the cavity of EtP5, forcing TCNB to complex with the exo‐wall of EtP5. Furthermore, we fabricate a vapochromic solid‐state supramolecular polymer by exploiting the exo‐wall complexation, which turns from brown to reddish brown or black after adsorption of alkyl aldehyde vapors. The adsorptive nature for alkyl aldehyde vapors comes from the unoccupied cavity of EtP5 based on C−H⋅⋅⋅π interactions. The vapochromic property is attributed to the change of the charge‐transfer interaction caused by molecular rearrangement induced by vapor‐capture in the solid‐state supramolecular polymer.

AbstractAn iron‐catalyzed denitrogenative rearrangement of 1,2,3,4‐tetrazole is developed over the competitive C(sp3)–H amination. This catalytic rearrangement reaction follows an unprecedented metalloradical activation mechanism. Employing the developed method, a wide number of complex‐N‐heterocyclic product classes have been accessed. The synthetic utility of this radical activation method is showcased with the short synthesis of a bioactive molecule. Collectively, this discovery underlines the progress of radical activation strategy that should find wide application in the perspective of medicinal chemistry, drug discovery and natural product synthesis research.

Published: January 2021

AbstractLow‐valent cobalt complexes equipped with chiral ligands can efficiently promote highly enantioselective (3+2) cycloadditions of alkyne‐tethered alkylidenecyclopropanes. The annulation allows to assemble bicyclic systems containing five‐membered rings in good yields and with excellent enantiomeric ratios. We also present a mechanistic discussion based on experimental and computational data, which support the involvement of CoI/CoIII catalytic cycles.

Published: January 2021

AbstractThe plastic film of the new plastic film reinforced pliable decorative veneer (PRPDSV) is used as a flexible reinforcement material and an adhesive material. It has good water resistance, impermeability, simple preparation and finishing processes, and no formaldehyde release. However, warpage phenomenon during hot pressing has been a bottleneck problem restricting its industrial development. In order to solve this problem solve, the study proposed a concave, and convex molds method, established an elastic–plastic FEA model of hot pressing processes of the PRPDSV using concave and convex molds with static/general static solution module in the nonlinear ABAQUS, and researched the effect on the performances of the PRPDSV from the parameters of temperature, pressure, and mold curvature radius theoretically and verified experimentally. Analysis results showed that the surface forming temperature had a great effect on warpage control for PRPDSV. The higher the temperature is, the smaller the curvature radius of the corresponding mold will be and the better the warpage will be. The curvature radius of the molds had a significant effect on the warpage control. Under the conditions with the same hot pressing parameters, the smaller the curvature radius is, and the better control on the warpage for the PRPDSV will be.

Published: January 2021

AbstractBiopolymeric chitosan is considered a promising encapsulating agent for textile applications due to its biocompatibility, lack of toxicity, antibacterial activity, high availability, and low cost. After cellulose, it is nature's most important organic compound. Also, chitosan has unique chemical properties due to its cationic charge in solution. Microencapsulation technologies play an important role in protecting the trapped material and in the durability of the effect, controlling the release rate. The application of chitosan microcapsules in textiles follows the current interest of industries in functionalization technologies that give different properties to products, such as aroma finish, insect repellency, antimicrobial activity, and thermal comfort. In this sense, methods of coacervation, ionic gelation, and LBL are presented for the production of chitosan‐based microcapsules and methods of textile finishing that incorporate them are presented, bath exhaustion, filling, dry drying cure, spraying, immersion, and grafting chemical. Finally, current trends in the textile market are identified and guidance on future developments.
Effect of chain extrender on the compatibility, mechanical and gas barrier properties of poly(butylene adipate‐co‐terephthalate)/poly(propylene carbonate) bio‐composites

Published: January 2021

AbstractBio‐composites consisting of poly(butylene adipate‐co‐terephthalate) (PBAT), poly(propylene carbonate) (PPC) and epoxy chain extender ADR 4468 were fabricated via melt blending using a torque rheometer. The relationship of the torque, melt viscosity, and molecular weight of the bio‐composites was established via polymeric liquid theory to estimate the real‐time chain extension reaction rate under different ADR contents. At the meantime, rheological behavior, thermal and mechanical properties, morphologies, gas barrier properties of the PBAT/PPC/ADR bio‐composites were systematically characterized. The corresponding results revealed that the water vapor transmission rate (WVTR) reduced by 50% under 30 phr (parts per hundreds of resin) PPC content. The addition of ADR is beneficial to improve the mechanical properties, thermal stability and phase dispersion of PBAT/PPC without affecting the water barrier property. With 3 phr ADR, the tensile stress and elongation at break were increased from 19.5 MPa and 1184% to 26.9 MPa and 1443%, respectively. In addition, the data of the torque rheometer revealed that the chain extension reaction rate and the melt viscosity was increased with the increasing ADR content, but the reaction rate was reduced with the excessive viscosity.
