Published: November 2022

Background

Coronavirus disease 2019 (Covid-19) is an evolving disease with newly generated evidence related to the clinical management of Covid-19 patients. We aimed to compare two online learning schedules for disseminating new cardiopulmonary resuscitation (CPR) guidelines in terms of knowledge gain and acceptability among nurses.

Methods

In a prospective randomized controlled study, 61 nurses trained in comprehensive cardiopulmonary life support (CCLS) were randomized to synchronous (n=31) and asynchronous learning groups (n= 30). The enhanced training module on CPR (ETMCPR) prepared by a team of experts was used to impart training to the nurses. Baseline data and pre-intervention knowledge of participants were collected using a structured demographic sheet and knowledge questionnaire (25 items) in a google form. Nurses in the synchronous group were provided training using ETMCPR through a licensed Zoom platform, while the nurses in the asynchronous group had access to the uploaded ETMCPR module in the e-learning platform. At the end of the intervention, the knowledge of the nurses was assessed along with their acceptability to the online learning schedule.

Results

Both schedules of online learning were effective in improving the knowledge scores of the nurses (11.93 [3.26] v. 21.15 [1.90], p=0.01 and 11.71 [3.12] v. 20.32 [1.71], p=0.01). The mean acceptability scores of nurses in the asynchronous group were statistically lower than in the synchronous group (38.93 [2.50] v. 42.5 [3.08], p=0.007).

Conclusion

Both synchronous and asynchronous schedules of online learning were effective in disseminating updated CPR guidelines; however, nurses in the synchronous group were more satisfied with the learning schedule.

Published: November 2022

Background

The Covid-19 pandemic has posed a challenge to organizing a safe clinical assessment for postgraduate degree candidates completing the residency programmes in various specialties. Although minimizing the risk of Covid-19 transmission is a priority, fulfilling the objectives of the assessment is equally important.

Methods

We conducted this study in the Department of Internal Medicine at our institute. Instead of physically examining patients, case scenarios that included history, clinical and investigational data of the cardiovascular system (CVS) were presented to the candidates. Performance was scored by both the conventional and the CVS objective-structured clinical examination (CVS-OSCE) method and compared.

Results

Clinical assessment examination of 27 candidates for the degree of Doctor of Medicine showed that the median cumulative score gained in narrating and analysing various differential diagnoses was lower compared to the mean cumulative score gained in arriving at a single correct diagnosis (50% [interquartile range—IQR 39%–64%]v. 79% [IQR 64%–100%], p<0.01). Most of the candidates agreed that case scenarios were good alternatives to the conventional physical examination amidst the pandemic.

Conclusion

CVS-OSCE-based assessment using structured case scenarios is a feasible and effective alternative for clinical skill assessment in high-stake examinations.

Сравнительную оценку коллекции сортов и образцов люпина белого по адаптивному потенциалу, стрессоустойчивости, урожайности и качеству семян проводили в 2019–2021 годах на полях коллекционного питомника агрономического факультета ФГБОУ ВО «Белгородский ГАУ». Были проанализированы четыре сорта и 26 сортообразцов люпина белого. Анализ адаптивности селекционного материала люпина показал, что сорта и образцы, которые отличались наибольшим коэффициентом адаптивности, имели высокую и стабильную по годам урожайность семян. В среднем наибольшие коэффициенты адаптивности (от 120,9 до 126,8%) получены у четырёх образцов, наименьшими (от 68,9 до 78,4%) отличались образцы СН 1022-09, СН 76-16 и СН 10-16. Показатель стрессоустойчивости сортов и образцов люпина белого варьировался в довольно широких пределах — от –14 до –191. По компенсаторной способности большинство сортов и образцов превысили стандарт. Урожайность семян сортов и образцов значительно колебалась в зависимости от метеорологических условий года, большинство из них по этому показателю достоверно превысили стандарт. По урожайности семян выделились образцы СН 17-14, СН 54-08 и СН 12-13, которые обеспечили прибавку по сравнению со стандартом 43–48%. У двух сортов, а также четырёх образцов превышение урожайности относительно стандарта составило 21–26%. Значительно уступали стандарту образцы СН 76-16 и СН 1022-09. По массе семян с одного растения большинство сортов и образцов люпина белого превзошли стандарт, у которого этот показатель составил 4,2 г. Содержание протеина в семенах варьировалось от 29,55 до 36,45% при 32,27% у стандарта. По содержанию алкалоидов в семенах все сорта и образцы, за исключением образца СН 2-17 (0,348%), относятся к группе малоалкалоидных и среднеалкалоидных

Competitive trial of white lupine genotypes took place at the Belgorod State Agrarian University in 2019–2021. Such traits as stress-resistance, productivity and seed quality were tested. Four varieties and 26 lines of white lupine performed as the objects of this study. Genotypes having the highest adaptive potential provided high and stable seed yield. Four genotypes had the highest adaptive capacity (from 120.9 to 126.8%) while such lines as SN 1022-09, SN 76-16 and SN 10-16 showed the lowest ones (from 68.9 to 78.4%). Stress resistance varied from –14 to –191. Compensatory effect of most genotypes exceeded the one of the standard. Seed productivity was greatly affected by environmental conditions; however, most of them performed better than the standard. SN 17-14, SN 54-08 and SN 12-13 showed yield increase of 43–48%. Two varieties and four lines showed increase in productivity of 21–26%. SN 76-16 and SN 1022-09 performed worse than the standard. Most genotypes exceeded the standard in seed mass from one plant (4.2 g). Protein content varied from 29.55 to 36.45% in seeds while the standard had 32.27%. Except for SN 2-17 (0.348%), all the genotypes had low or average concentration of alkaloids in seeds.

Dissolution of Soda-Lime Glass in Beverages
Authors: Badoni Vedant
Published: November 2022

The objective of this experiment was to measure and analyze the effect of various beverages on soda-lime silicate glasses. The beverages included milk, orange juice, and coca-cola. It was hypothesized that these common beverages would have little effect on the glass particles by causing minimal degradation. XRD on our samples revealed that our glass was amorphous. The results of this experiment supported this hypothesis. The pH and weight-loss measurements both changed very little over the course of the experiment, indicating that the soda-lime silicate glasses did not dissolve very much in the beverages nor had much of an effect on them. It is recommended that more beverages be tried with longer time durations to determine the aggregate effect of acidic liquids on glass bottles and whether or not they are safe for drinking.
The Mechanochemical Fries Rearrangement: Manipulating Isomer Ratios in the Synthesis of p-Hydroxyacetophenone at Different Scales
Authors: Baier Daniel , Rensch Tilo , Bergheim Konrad , Pietryga Viktoria , Graetz Sven , Borchardt Lars
Published: November 2022

Here, we present the first mechanochemical Fries rearrangement for the industrially important synthesis of para hydroxyacetophenone, inside a ball mill and a twin-screw extruder. Our approach leads to quantitive conversion in as little as 90 minutes. Furthermore, the utilisation of liquid-assisted grinding can shift the isomer ratio resulting in an excess of the desired para product. The multigram scale-up via a continuous extrusion process leads to similar results in only three minutes of residence time while completely avoiding solvents. The extrusion temperature of 75-100 °C can even further be reduced by combining extrusion at 50°C with a subsequent ageing step.
Understanding Charge Recombination of TiO2 using Ultrafast mid-Infrared Spectroscopy: The Effect of Photogenerated Holes
Authors: El-Zohry Ahmed M.
Published: November 2022

We utilize mid-infrared probe to explore the mechanism for the dramatic charge recombination process of the photogenerated charges within the band gap of TiO2. Using the low-energy photons probes the free electrons in the conduction band of TiO2 and upon trapping to shallow-trap states. We found that > 70% of the photogenerated charges disappear from the conduction band in the first few nanoseconds, due to electron trapping or charge recombination. We compare the behavior of free electron dynamics within the bandgap of TiO2 and upon generating them across the interface with adsorbing organic dyes. This comparison shows that the main driving force of dramatic charge recombination of photogenerated charges is the presence of hole within the band-gap of TiO2 or close to the interface of TiO2. Once, the hole is far from the TiO2 surface, the electron trapping process is hindered and almost 100% of photogenerated charges can live up till nanoseconds. This paper allows for further understandings of the charge trapping and charge recombination processes in TiO2 and in other semiconductors.

Published: November 2022

Extensive research has been devoted to the development of thermally activated delayed fluorescence emitters showing pure-blue emission, especially for use in lighting and full-color display applications. Herein, we report a novel weak donor, 1,4-azaborine (AZB), with complementary electronic and structural properties compared to the widely used dimethylacridan (DMAC) or carbazole (Cz) donors. Coupled with a triazine acceptor, AZB-Ph-TRZ is the direct structural analogue of the high-performance and well-studied green TADF emitter DMAC-TRZ, and has a ΔEST of 0.39 eV, a photoluminescence quantum yield (FPL) of 27% and a λPL at 415 nm in 10 wt% doped mCP films. A shortened analogue AZB-TRZ possesses red-shifted emission with a reduced singlet-triplet gap (ΔEST of 0.01 eV) and fast reverse intersystem crossing (kRISC, of 5 × 106 s-1) in mCP. Despite a moderate FPL of 34%, OLEDs with AZB-TRZ in mCP showed sky-blue emission with CIE1931(x,y) of (0.22,0.39) and a maximum external quantum efficiency (EQEmax) of 10.5%. Expanding the chemist’s toolkit for the design of blue donor-acceptor TADF materials will enable yet further advances in the future, as AZB is paired with a wider range of acceptor groups.
Mechanochemical assisted chemoselective and stereoselective hydrogen-bonding catalyzed addition of dithiomalonates to enones

Published: November 2022

Dithiomalonates proved to be active nucleophiles in the stereoselective additions to chalcones, dienones, and en-ynones affording the desired Michael adducts with good to high yields and enantioselectivities. In contrast, the analogous dibenzyl malonate remained inactive. Bifunctional Cinchona-based squaramides secured the effective chirality transfer and the selectivity towards Michael adducts of various bisthiomalonates following the soft enolization approach. The thioester’s nature impacted the reactivity and stability of the reactants or products. While the reactions performed in solution led to the products, the required time along with byproducts formation such as thio-Michael adducts, limiting the applicability of reactive dithioesters. On the contrary, reactions performed under solvent-free, ball milling conditions furnished adducts up to six times faster, with subtly or no byproduct generation. Therefore, the mechanochemical approach revealed to be an effective tool for supporting the hardly effective reactions under standard solution conditions. Detailed KS-DFT studies supported the experimental observations shedding more light on the intricate active nucleophile formation, and different chemical reaction pathways, as well as indicating the crucial transitions state governing the observed stereoselectivities
Divergent Mechanistic Pathways for Copper(I) Hydrophosphination Catalysis: Understanding that Allows for Diastereoselective Hydrophosphination of a Tri-substituted Styrene
Authors: Dannenberg Steven , Seth Dennis , Finfer Emma , Waterman Rory
Published: November 2022

Readily available and bench-stable Cu(acac)2 (1) addresses many challenges in exploratory hydrophosphination catalysis. Mechanistic investigations were performed to answer questions that remain about the reactivity of 1, the role of light in the catalysis, and to provide direction for further study. A divergent Hammett plot indicates differing mechanisms based on electron density at the alkene substrate. A radical process was eliminated based on trapping reactions and in-situ EPR experiments. Isotopic labeling experiments, a zwitterionic trapping experiment, stoichiometric model reactions, and catalytic reactions using proxy intermediates indicate that both conjugate addition and insertion-based mechanistic pathways occur with this system, depending on the unsaturated substrate. Computational analysis indicates that the lowest energy transition is a ligand-to-metal charge transfer (LMCT) from the phosphido ligand where the LUMO has significant Cu–P antibonding character, suggesting that a weakened Cu–P bond accelerates insertion under photocatalytic conditions. This hypothesis explains the greater activity of 1 compared to copper-catalyzed hydrophosphination reports and appears to be a general phenomenon for copper(I) catalysts. These results have been leveraged to achieve heretofore unknown catalytic hydrophosphination reactivity, namely the diastereoselective hydrophosphination of a tri-substituted styrene substrate.
Intention to Stay or Return? Motivation and Factors Influencing Indonesian Nurses Working in Japan
Authors: Harahap Susi Mariani , Gunawan Tedi
Published: November 2022

In 2008, Japan agreed to recruit Indonesian nurses to work as nurses as a part of the Indonesia-Japan Economic Partnership Agreement (IJEPA). This study aimed to explore the motivation behind working in Japan and factors behind the Indonesian nurses' intention to stay in Japan or return to Indonesia after the contract is terminated. This descriptive quantitative study used an online survey involving 103 respondents. Results revealed that a high rate of remuneration and better working environment were the pull factors whereas low salarie, and poor working conditions in Indonesia were the major reasons why Indonesian nurses wanted to work in Japan.  Of the 103 respondents, 71 % stated that they intended to remain in Japan, whereas 29 % preferred to return to Indonesia after the contract is terminated.

Manny disc brake are produced at conventional machinery workshop. But, the optimum value of disc brake based on heat dissipation, and the safety is unknown. One of the causes of vehicle accidents is the vehicle factor (brake failure). Prolonged and continuous braking on the disc brake can result in fadding. Continuous stress generation can decrease fatigue life. The required material and the right number of holes are needed to solve this problem. The Purpose of this research is to get the optimum temperature and stress value. In this study, simulations were carried out with CAE software on disc brakes with materials Al 7075- T6, SS 304, gray cast iron and the number of ventilation holes 36, 48, 60. The results show that the disc brake with Al 7075-T6 material and 60 ventilaton holes has the best heat dissipation with 38,005ᴼC temperature value. Material gray cast iron with number of ventilation holes 48 produces the lower equivalent stress with 89,272 Mpa. From the research it can be concluded, disc brake with higher density,has higher temperature too. The greater tensile strength of disc brake material, resulting the lower equivalent stress. The gray cast iron material and the number of ventilation holes 48 is the most optimal in temperature absorption, the longest fatigue life, and the highest fatigue safety factor, with a temperature value of 54.99ᴼC, a fatigue life of 100000000 cycles, and an FOS of 3.34.The more number of ventilation holes, has the lower of temperature result but the higher stress concentration.
