Background

The rapidly spreading nature of Covid-19 virus associated with its high mortality and mortality rate is triggering an unprecedented public health crisis. The study assessed the availability, price, and affordability of medicines used in the management of Covid-19 in health facilities of Dessie town.

Methods

A retrospective cross-sectional study design was employed in the health facilities of Dessie town from September 1 to September 20, 2021. Data was collected using a standard checklist adopted from the Logistics Indicator Assessment Tool and WHO/HAI. WHO/HAI methodology was applied to select the surveyed health facilities (30) and medicines (44). The daily wage of the lowest-paid unskilled government worker is used to estimate affordability.

Results

Fifteen and five medicines were not found at all public and private health facilities, respectively. The originator brand (OB) and lowest price generic (LPG) availability in private health facilities was 2.03% and 51.33%, respectively. In the public sector, the availability of OB and LPG was 0% and 34.44%, respectively. In public and private health facilities, the mean number of stock-outs was 2.25 and 2.91, and the mean number of stock-out days was 177.83 and 106.16 days, respectively. Eight and one LPG medicines were out of stock in public and private health facilities, respectively. Eight (33.33%) and 6 (28.57%) had higher prices than international prices in private and public health facilities, respectively. The median price ratio in public and private health facilities ranged from 0.02 and 3.05 and 0.04 to 2.70, respectively. Eighty percent of the products were unaffordable in both sectors.

Conclusions

The availability of medicines was low. One-third of the medicines had higher prices than international prices. Eighty percent of the products were unaffordable. The regular supply of these medicines is crucial for better management of the disease.

Published: December 2022

Since its recognition in 1994 as the causative agent of human flea-borne spotted fever, Rickettsia felis, has been detected worldwide in over 40 different arthropod species. The cat flea, Ctenocephalides felis, is a well-described biological vector of R. felis. Unique to insect-borne rickettsiae, R. felis can employ multiple routes of infection including inoculation via salivary secretions and potentially infectious flea feces into the skin of vertebrate hosts. Yet, little is known of the molecular interactions governing flea infection and subsequent transmission of R. felis. While the obligate intracellular nature of rickettsiae has hampered the function of large-scale mutagenesis strategies, studies have shown the efficiency of mariner-based transposon systems in Rickettsiales. Thus, this study aimed to assess R. felis genetic mutants in a flea transmission model to elucidate genes involved in vector infection. A Himar1 transposase was used to generate R. felis transformants, in which subsequent genome sequencing revealed a transposon insertion near the 3’ end of sca1. Alterations in sca1 expression resulted in unique infection phenotypes. While the R. felis sca1::tn mutant portrayed enhanced growth kinetics compared to R. felis wild-type during in vitro culture, rickettsial loads were significantly reduced during flea infection. As a consequence of decreased rickettsial loads within infected donor fleas, R. felis sca1::tn exhibited limited transmission potential. Thus, the use of a biologically relevant model provides evidence of a defective phenotype associated with R. felis sca1::tn during flea infection.

Authors: Teixeira Catarina , De Carvalho Luiz Marcelo
Published: December 2022

Este artigo tem como objetivo descrever e compreender as perspectivas de formação continuada abordada nas teses em Educação Ambiental que focam suas investigações nos processos de formação continuada de professores produzidas no Brasil. Essa pesquisa se insere na linha de investigações do tipo estado da arte, tendo como fonte o banco de dados do Projeto EArte, onde foram identificadas 36 teses que se voltam para essa temática. Para analisar os trabalhos consideramos como referência as perspectivas de formação: tecnicista, prática e crítica. A análise realizada permitiu apontar que em praticamente metade das teses analisadas não foi possível identificar a perspectiva que orientou o desenvolvimento do processo de formação, pois elas se encontravam em uma transição entre as perspectivas tecnicistas, prática e crítica, gerando uma certa incongruência em determinadas passagens entre essas diferentes perspectivas. Este panorama é um importante direcionamento para futuras pesquisas e/ou práticas de formação continuada de professores no campo da EA.

Recent studies have found that oxygen saturation (SpO2) variability analysis has potential for noninvasive assessment of the functional connectivity of cardiorespiratory control systems during hypoxia. Patients with sepsis have suboptimal tissue oxygenation and impaired organ system connectivity. Our objective with this report was to highlight the potential use for SpO2 variability analysis in predicting intensive care survival in patients with sepsis. MIMIC‐III clinical data of 164 adults meeting Sepsis‐3 criteria and with 30 min of SpO2 and respiratory rate data were analyzed. The complexity of SpO2 signals was measured through various entropy calculations such as sample entropy and multiscale entropy analysis. The sequential organ failure assessment (SOFA) score was calculated to assess the severity of sepsis and multiorgan failure. While the standard deviation of SpO2 signals was comparable in the non‐survivor and survivor groups, non‐survivors had significantly lower SpO2 entropy than those who survived their ICU stay (0.107 ± 0.084 vs. 0.070 ± 0.083, p < 0.05). According to Cox regression analysis, higher SpO2 entropy was a predictor of survival in patients with sepsis. Multivariate analysis also showed that the prognostic value of SpO2 entropy was independent of other covariates such as age, SOFA score, mean SpO2, and ventilation status. When SpO2 entropy was combined with mean SpO2, the composite had a significantly higher performance in prediction of survival. Analysis of SpO2 entropy can predict patient outcome, and when combined with SpO2 mean, can provide improved prognostic information. The prognostic power is on par with the SOFA score. This analysis can easily be incorporated into current ICU practice and has potential for noninvasive assessment of critically ill patients.
Redesigning the surveillance of in vitro diagnostic medical devices and of medical laboratory performance by quality control in the traceability era
Authors: Panteghini Mauro
Published: December 2022

IVD manufacturers have total responsibility in terms of the traceability of marketed in vitro diagnostic medical devices (IVD-MD). This includes the provision of a quality control (QC) material as a part of the measuring system, suitable for traceability verification and alignment surveillance by end-users in daily practice. This material [to be used for the internal QC (IQC) component I as described in this paper] should have unbiased target values and an acceptability range corresponding to analytical performance specifications (APS) for suitable (expanded) measurement uncertainty (MU) on clinical samples. On the other hand, medical laboratories (by the IQC component II as described in this paper) should improve the IQC process and its judging criteria to establish a direct link between their performance, estimated as MU of provided results, and APS defined according to recommended models to apply corrective actions if the performance is worsening with the risk to jeopardize the clinical validity of test results. The participation to external quality assessment (EQA) programs that meet specific metrological criteria is also central to the evaluation of performance of IVD-MDs and of medical laboratories in terms of harmonization and clinical suitability of their measurements. In addition to the use of commutable materials, in this type of EQA it is necessary to assign values to them with selected reference procedures and to define and apply maximum allowable APS to substantiate the suitability of laboratory measurements in the clinical setting.
A new extension of the beta generator of distributions
Authors: Muhammad Mustapha , Liu Lixia
Published: December 2022

In this paper, we introduced a new extension of the beta generator of distributions. Some important properties of the model are discussed, such as the series representation, quantile function, moments, Rényi entropy, and order statistics. Three special members are discussed, namely, the new extended beta exponential (NEBE), new extended beta uniform (NEBU), and new extended beta half logistic (NEBH). The model parameters estimation was achieved by the method of maximum likelihood and the Bayes estimation under square error loss function (SEL); the estimators were examined by simulation studies and it was a very good result as discussed by the bias and mean square error (MSE) of the estimators. Two real data applications are provided to illustrate the importance of the new model in practice.
Metals and metal oxides polymer frameworks as advanced anticorrosive materials: design, performance, and future direction
Authors: Verma Chandrabhan , Hussain Chaudhery Mustansar , Quraishi Mumtaz A. , Rhee Kyong Yop
Published: December 2022

Metals (Ms) and metal oxides (MOs) possess a strong tendency to coordinate and combine with organic polymers to form respective metal–polymer frameworks (MPFs) and metal oxide polymer frameworks (MOPFs). MPFs and MOPFs can be regarded as composites of organic polymers. MPFs and MOPFs are widely used for industrial and biological applications including as anticorrosive materials in the aqueous phase as well as in the coating conditions. The presence of the Ms and MOs in the polymer coatings improves the corrosion inhibition potential of MPFs and MOPFs by improving their self-healing properties. The Ms and MOs fill the micropores and cracks through which corrosive species such as water, oxygen, and corrosive ions and salts can diffuse and destroy the coating structures. Therefore, the Ms and MOs enhance the durability as well as the effectiveness of the polymer coatings. The present review article is intended to describe the corrosion inhibition potential of some MPFs and MOPFs of some most frequently utilized transition metal elements such as Ti, Si, Zn, Ce, Ag, and Au. The mechanism of corrosion inhibition of MPFs and MOPFs is also described in the presence and absence of metal and metal oxides.

Chae, S, Bailey, CA, Hill, DW, McMullen, SM, Moses, SA, and Vingren, JL. Acute kinetic and kinematic responses to rest redistribution with heavier loads in resistance-trained men. J Strength Cond Res XX(X): 000–000, 2022—The purpose of this study was to examine mechanical responses to rest redistribution with heavier loads (RR + L) in resistance-trained men. Eight men (23.0 ± 4.8 years, 1.76 ± 0.06 m, 78.5 ± 8.6 kg, back squat [BS] one-repetition maximum [1RM] of 138.7 ± 27.9 kg) completed 2 BS exercise sessions in a counterbalanced and a randomized order; RR + L: 4 sets of (2 × 5) repetitions with 90-second interset rest and 30-second intraset rest using 75% BS 1RM and traditional sets (TS): 4 sets of 10 repetitions with 120-second interset rest using 70% BS 1RM. During the concentric phase, mean force (

), velocity (

), and power (

) were collected for each repetition using a linear position transducer and analyzed the first 3 sets. Compared with TS, RR + L resulted in significantly greater

(1820 ± 260 N vs. 1753 ± 248 N; p < 0.001; g = 0.25) and lower

(0.47 ± 0.07 m·s−1 vs. 0.50 ± 0.09 m·s−1; p = 0.005; g = −0.35). However, no significant difference in

(836 ± 165 W vs. 871 ± 197 W; p = 0.082; g = −0.18) was found between RR + L and TS. In conclusion, the lack of difference in

might be the result of the combination of greater

and lower

for RR + L compared with TS. Therefore, practitioners may consider using RR + L to augment

without compromising

and increasing total rest time. However, given the approximate 4% difference in

, the effect of RR + L training on chronic strength adaptation is expected to be small.
The Relationship of Lower-Body, Multijoint, Isometric and Dynamic Neuromuscular Assessment Variables With Snatch, and Clean and Jerk Performance in Competitive Weightlifters: A Meta-Analysis
Authors: Joffe Shaun A. , Price Phil , Chavda Shyam , Shaw Joseph , Tallent Jamie
Published: December 2022

The purpose of this meta-analysis was to synthesize the literature and provide a robust estimate of the correlations between lower-body, multijoint, isometric and dynamic neuromuscular assessment variables and snatch (SN) and clean and jerk (C&J) performance in competitive weightlifters. A comprehensive search through 3 electronic databases (PubMed, SPORTDiscus, and Web of Science) returned 12 studies that met the inclusion criteria. Meta-analyses were performed on Pearson's correlations between SN and C&J performance and 15 variables from 5 neuromuscular assessments—countermovement jump (CMJ), squat jump (SJ), isometric midthigh pull (IMTP), back squat (BS), and front squat (FS) one repetition maximum (1RM). The FS and BS 1RM exhibited nearly perfect correlations (r = 0.93 to 0.94), whereas the IMTP peak force exhibited very large correlations (r = 0.83 to 0.85). The IMTP force at 250 ms exhibited very large correlations (r = 0.77 to 0.78), and the CMJ and SJ peak power exhibited very large to nearly perfect correlations (r = 0.88 to 0.92). These findings illustrate the importance of lower-body maximal and time-limited force-producing capabilities in weightlifters. Moreover, each assessment offers at least one variable that exhibits a correlation of >0.70. Therefore, these assessments may be used to gauge weightlifting performance potential.
La compassion managériale comme propulseur de la santé organisationnelle en temps de perturbations
Authors: Grenier Simon , Montani Francesco , Gagnon Jean-François , Dupuis Alexandrine
Published: December 2022

Les gestionnaires en organisation sont appelés à jouer un rôle clé dans la préservation et la promotion de la santé organisationnelle en temps de perturbations ou de changements sociaux importants. Pourtant, les données scientifiques sont limitées par rapport aux conditions permettant aux gestionnaires de mettre en œuvre des actions pour soutenir la santé organisationnelle. Porter un intérêt à cette question est crucial considérant que les gestionnaires sont parmi les acteurs organisationnels les plus affectés par des problèmes de santé psychologique et ce, tout en étant ceux qui doivent affronter et réduire l’impact des perturbations externes liées aux changements sociaux qui affectent l’organisation. L’objectif du présent article est de proposer un modèle conceptuel clarifiant le rôle de la compassion managériale en tant que levier de la santé organisationnelle à travers l’identification des mécanismes médiateurs et d’une condition modératrice propre à l’état psychologique des gestionnaires eux-mêmes. De ce fait, nous suggérons que les processus organisationnels de type psychosocial jouent un rôle médiateur dans la relation entre la compassion managériale et la santé organisationnelle alors que la détresse managériale, induite par des stresseurs extraorganisationnels, agit à titre de modérateur. À cette fin, nous proposons d’intégrer la théorie des ressources cognitives et les écrits sur la détresse au travail pour élaborer notre modèle. Les contributions de ce modèle à l’avancement de la théorie sur la compassion managériale et la santé organisationnelle en temps de perturbations sociales et économiques seront discutées.

Purpose

The aim of this study is to comprehensively analyze the publications of anterior cruciate ligament reconstruction (ACLR) research and display the current research status in this field.

Methods

Articles regarding ACLR research published before October 7, 2021, were downloaded from the Web of Science Core Collection. Excel 2016 and Bibliometric website were used to analyze the annual article trends and international cooperation network. CiteSpace V and VOSviewer were used to perform co-occurrence and citation analyses for journals, institutions, authors, cocitation authors and keywords. Burst keyword detection was also performed with CiteSpace V.

Results

A total of 12 223 ACLR articles were identified. The American Journal of Sports Medicine (1636 publications, 92,310 citations), the Pennsylvania Commonwealth System of Higher Education (624 publications, 25,304 citations) and Freddie H. Fu (321 publications, 15,245 citations) were journals, institutions and authors with the most publications and citations, respectively. Patellar tendon was the keyword with the most occurrences (1618 times) and return to sport was the keyword with the most burst strength (burst strength: 46.99).

Conclusion

ACLR-related publications showed a rapid increasing trend since 1990. A large number of articles have been published by authors from different institutions and countries, some of which have gained great academic influence. Based on keyword analysis, patellar tendon is identified as the research hotspot and return to sport is identified as the current research frontier.
Recurrence of instability after Latarjet procedure: causes, results and treatment algorithm
Authors: Calvo Emilio , Valencia María , Foruria Antonio Maria , Gonzalez Juan Aguilar
Published: December 2022

Latarjet modifies the anatomy of the shoulder, and subsequent revision surgery is challenging.

It is mandatory to determine the cause of recurrence in order to select the best treatment option. A CT scan is needed to measure glenoid track and evaluate coracoid graft status: position, degree of consolidation, and osteolysis.

Conservative management can be advocated in selected patients in whom the instability level does not interfere with the activities they wish to perform. Surgical treatment is based on the glenoid track measurement and coracoid graft suitability.

The coracoid graft is considered suitable if it preserves the conjoint tendon insertion, does not show osteolysis, and is large enough to reconstruct the glenoid surface. Adding a remplissage is recommended for those cases with a coracoid graft insufficient to convert large off-track Hill–Sachs lesions into on-track.

If the coracoid graft is suitable to reconstruct bone defects in terms of size and viability but is poorly positioned or avulsed, graft repositioning can be a valid option.

In patients with unsuitable coracoid bone graft, free bone graft is the revision technique of choice. The size of the graft should be large enough to restore the glenoid surface and to convert any off-track Hill–Sachs lesion into on-track.

There is a small group of patients in whom bone defects were properly addressed but Latarjet failed due to hyperlaxity or poor soft tissue quality. Extraarticular capsular reinforcement is suggested in this population.
Nitric oxide synthase phosphorylation in fetoplacental endothelium is enhanced by agonism of Piezo1 mechanosensor in small for gestational age babies
Authors: Morley L C , Debant M , Gaunt H J , Simpson N A B , Beech D J
Published: December 2022

Lay summary

Friction caused by blood flowing across cells that line blood vessels (endothelial cells) activates sensors of mechanical force. This produces nitric oxide (NO) which widens placental blood vessels, enabling more blood flow to the baby. This study sought to determine whether the mechanical sensor, Piezo1, is important for NO production in fetoplacental endothelial cells (FpECs) and whether the steps in this pathway are different in small for gestational age (SGA) babies, where placental blood flow is often altered. We showed that in healthy FpECs, blood flow increased NO signalling. We suggest that in SGA babies, FpECs have an increase in baseline levels of NO signalling, suggestive of a compensatory drive. Treating healthy and SGA cells with a Piezo1 chemical activator, Yoda1, upregulated NO signalling. This shows that Piezo1 is linked to NO and that in SGA, FpECs have the capacity to further increase NO. Further research will establish whether Piezo1 enhancement leads to increased blood flow in the placenta. If so, Piezo1 could be a new target for developing treatments to prevent poor growth of babies in the womb.
Enumeration Of Bifidobacterium Spp., Lactobacillus Acidophilus and Starter Cultures from Commercial Probiotic Yogurts and Freeze-Dried Yogurt Starter Mixes
Authors: Demirci Talha
Published: December 2022

Probiotic yogurt is a popular functional food to deliver of probiotic cells for the health-enhancing effects worldwide. The viability of probiotics in yogurt before consumption is the most important factor to providing desired effects, however, probiotic microorganisms have occasionally inadequate viability in marketable food products. In this current study, Bifidobacterium spp., L. acidophilus and yoghurt starter bacteria enumerations were made in commercial probiotic yoghurt and freeze-dried yogurt mixes. RCA 5.3 and MRS 5.2 media were used for L. delbrueckii subsp. bulgaricus counting, ST Agar and M17 Agar were used for Stretococcus thermophilus counts. While using MRS-Bile Agar and RCA-Clindamycin Agar for L. acidophilus enumeration, Bifidobacterium spp. counts were performed using MRS-NNLP medium. 5 out of yoghurt samples (A, C, D, and E) did not reveal satisfactory recovery (< 5 log CFU/g) for L. delbrueckii subsp. bulgaricus colonies on MRS 5.2 Agar while L. delbrueckii subsp. bulgaricus colony counts on RCA 5.3 Agar below 5 log CFU/g for same tested 4 samples (A, C, D, and E). The recovery rates over 9 log CFU/g were obtained in the enumerations made for all yogurt samples on both ST and M17 media. The problem of insufficient recovery rates that occurred for L. delbrueckii subsp. bulgaricus in some yogurt samples was not valid for S. thermophilus. This work indicated that high amounts of L. acidophilus were detected on both media in both of the two yoghurt samples declared as L. acidophilus on the label (F and G). On the other hand, bifidobacteria was determined above 5 log CFU/g in only 1 yoghurt sample (B) out of 7 probiotic yoghurts claimed to be Bifidobacterium spp. This study reveals relevant information on probiotic and starter counts of commercial probiotic yogurts in Turkey and discusses in detail the possible reasons for the results obtained.

Published: December 2022

This research was carried out in 2016 in order to determine the most suitable germination temperatures of the seeds of 4 different forage pea varieties (Furkan, Bilgehan, Özkaynak, Taşkent) stored in paper bags for 7 years and 8 years at room temperature, and the damage that may occur on plants at subzero temperatures after germination were carried out. In the experiment, which was established with 4 replications in the "Random Plots in Factorial Experiment Design" under laboratory conditions; Number of germinated seeds on the 4th, 7th and 10th days at 5°C, 15°C, 25°C and 35°C temperatures, and after the 10th day, frost damage in plants kept at -5°C for 3 days, root length, stem length, root length/stem length ratio was determined. According to the findings of the research, while the best germination took place at 25°C, the most suitable germination temperature was determined between 15°C and 25°C. In addition, it was revealed that the seeds produced in 2008 germinated more than the seeds produced in 2016. On the other hand, among the plants kept at -5°C, it was determined that the varieties named Taşkent and Özkaynak, which were germinated at 15°C and 25°C, suffered the least damage, and the highest average in the comparison of the total height values was found in the Taşkent variety germinated at 25°C.
Determination of the ADF and IVOMD Content of Sugarcane Using Near Infrared Spectroscopy Coupled with Chemometrics
Authors: Cataltas Ozcan , Tutuncu Kemal
Published: December 2022

Sugarcane is a plant whose quality parameters are required to be determined both for being one of the substances used in sugar production and for being used as animal feed. Near-infrared spectroscopy is a technique that has already been used for predicting the parameters of various plants and has gained popularity in recent years. This study proposes a near-infrared spectroscopy-based model for the rapid and effortless analysis of acid detergent fiber fraction and vitro organic matter digestibility parameters of the sugarcane plant. Partial least squares regression was combined with common preprocessing methods for modeling. This model yielded an R2CV value of 0.935 and 0.953 for the acid detergent fiber fraction and vitro organic matter digestibility parameters, respectively. Then, the spectra from three handheld spectrometers were combined using a proposed combination method to generate new spectra with higher spectral resolution. New models were built using these generated spectra and compared to the previous result. Obtained results showed that combining spectra from different spectrometers can improve model performance.

Published: December 2022

Tomatoes are one of the most used vegetables. There are varieties that can grow in different climates. The taste, usage area and commercial value of each are different from each other. For this reason, identifying and sorting tomato species after the production stage is a problem. In addition, since tomato is a sensitive vegetable, it is extremely important to separate it from a distance. For this purpose, the classification of tomato images belonging to 9 different tomato species was carried out in the study. In total, a dataset containing 6810 tomato images in 9 classes was used. Three different pre-trained Convolutional Neural Network (CNN) models were used with the transfer learning method to classify the images. AlexNet, InceptionV3 and VGG16 models were used for classification. As a result of the classifications made, the highest classification belongs to the AlexNet model with 100%. Evaluation of the performances of the models was also made with precision, recall, F1 Score and specificity performance metrics. It is foreseen that the proposed methods can be used for the separation of tomatoes.

Factors Affecting Teachers’ Work Engagement: The Case of Private School Teachers in Jakarta Metropolitan, Indonesia
Authors: Sudibjo Niko , Riantini Maria Goreti Dwiatmi
Published: December 2022

Previous studies found the phenomenon that the level of work engagement (WE) is deficient in various parts of the world, including in educational organizations. This research aims to analyze how perceived organizational support (POS) and servant leadership (SL) in schools affect teachers' WE. Additionally, this research also aims to examine the mediating role of meaningful work (MW). This research was conducted with a cross-sectional study design with the PLS-SEM method. The research data was obtained through a self-reported questionnaire from 176 school teachers in Jakarta and Bogor, Indonesia. The results revealed that MW is the strongest predictor with the highest effect on teachers' WE. In addition, POS is the strongest predictor of teachers' MW. However, the role of MW as a mediator in this study has a smaller effect than the direct relationship between POS and teachers’ WE and between SL and teachers' WE. Therefore, schools need to provide maximum support to teachers and ensure that teachers can interpret their work and realize that their work has a positive contribution to have high work engagement

El objetivo del estudio que se presenta es indagar sobre cómo abordan los docentes de la comunidad de Castilla y León la educación sexual y la diversidad sexual en las prácticas educativas que emplean para la inclusión del alumnado LGTBIQ+ en las aulas y para la gestión de las diferencias entre estudiantes, en los centros educativos de la comunidad. Se inscribe en un marco epistémico interpretativo y metodología cualitativa en el ámbito educativo, que examina las competencias docentes y la realidad de las aulas. Se reunió una muestra de 17 docentes en activo en centros educativos de la comunidad autónoma con quienes se utilizó una entrevista semiestructurada para la recogida de datos. El análisis de datos reveló carencias formativas en el profesorado en relación con la terminología y las estrategias metodológicas para abordar la diversidad sexual en el aula, que lleva consigo la ausencia de prácticas educativas que aborden esta temática. Estos resultados ponen de manifiesto la necesidad de formación del profesorado en aspectos relacionadas con la coeducación y el abordaje de la diversidad sexual en los centros educativos. Se considera fundamental la implementación de protocolos, guías de actuación, programas, así como la visibilización de figuras referentes en sus proyectos educativos, que promuevan la plena inclusión del alumnado y prevengan la discriminación
The policy of the Soviet state and the Renovationist schism in Kuban, region (1922–1923)
Authors: Kiyashko Nikita
Published: December 2022

This article reconstructs the evolution of renovationist schism in the Kuban Diocese, which was one of the main outposts of the schism in the country, based on a wide range of unpublished sources from state and departmental archives. A characteristic feature of the development of the renovationist movement in the region was its support by the overwhelming majority of the clergy of the diocese. More than twelve Kuban clerics became self-appointed hierarchs, some were members of the governing renovationist bodies. The socio-political specifics of the Cossacks and their involvement in the events of the Civil War were reflected in church life, and the clergy, through cooperation with the authorities, sought to whitewash their ministry during the reign of the Volunteer Army. Despite the high religiosity, unlike other southern regions, the anti-renewal movement was local in nature and did not become widespread. As a result of the most severe repressive measures, dozens of clergy who did not recognize the renovationist «Higher Church Administration» (VTsU) were expelled from the region, including the vicar Bishop of Yeisk, Eusebius (Rozhdestvensky), archpriests Alexander Makov and Alexander Purlevsky, etc. The direct connection of the Kuban clergy with the leaders of renovationism, the highest bodies of the Soviet vertical and the leadership of the security agencies provided the necessary support for the schism and the preservation of monopoly in church life for two decades.

Рибофлавін відіграє важливу роль у широкому діапазоні біологічних процесів. Метою роботи було встановити особливості культивування штаму-продуцента рибофлавіну Bacillus subtilis IFBG MK-1A у біореакторі. Показано, що за культивування штаму в колбах об’ємом 1 дм3 накопичення рибофлавіну становило 13,9 г/дм3 на 66-ту годину культивування. Масштабування процесу культивування з підживленням проводили в біореакторі об’ємом 10 дм3. Встановлено, що оптимальний об’єм внесення підживлення становить 47 %, а кількість аміачної води, необхідної для стабілізації рН та накопичення рибофлавіну — 8 % об’єму середо вища до інокуляції. Визначено, що конверсія глюкози становить 12%, накопичення рибофлавіну — 19,1 г/дм3 (за культивування з підживленням). Показано, що за умов культивування штаму B. subtilis IFBG MK-1A у біо- реакторі з періодичним підживленням істотно збільшується накопичення рибофлавіну (на 65 %) порівняно з накопиченням рибофлавіну в колбах.

Review on C60S Spectra
Authors: Yunus M. , Nizam R.
Published: December 2022

We present the review on infrared and Raman spectra of C60S which have been calculated byvMohd Yunus & Rashid Nizam through the Hartree–Fock method. They found four isomers:bclosed [6,6]C60S, open [6,6]C60S, closed [5,6]C60S, and open [5,6]C60S. The simulated spectrabwere calculated in [13, 14] for closed [5,6]C60S and closed [6,6]C60S isomers, but Hartree–Fockbmethod did not converge for open [5,6]C60S and open [6,6]C60S isomers. The computed spectrum is divided into fourbranges of frequencies for C60S; these are as follows: 0–600 cm-1,600–800 cm-1, 800–1200 cm-1, and 1200–1650 cm-1. The results are analyzed in each range separately. The strong intense lines are revealed in closed [6,6]C60S, rather than in the closed [5,6]C60S isomer for both Raman and IR spectra. The energy barriers equal to 233.2 kJ · mol-1 and 1.2 kJ · mol-1 are obtained in [13, 14] for the conversion of closed [6,6]C60S isomer to open [5,6]C60S isomer. The values of 82.0 kJ · mol-1 and 150.5 kJ · mol-1 are given in [13, 14] for the inverse conversion from open [5,6]C60S to closed [6,6]C60S isomer.

Методом Брiджмена iз стехiометричного розплаву компонентiв вирощено шаруватi кристали In2Se3, якi, по даним рентгеноструктурного аналiзу, є неоднорiдними: частина зразкiв, отриманих iз одного i того ж зливку, мiстять у собi лише фазу гексагонального α-In2Se3, а в iншiй частинi виявлено включення кристалiчної фази In6Se7. Вкраплення бiльш вузькозонного напiвпровiдника в матрицю α-In2Se3 спричиняють струмову нестабiльнiсть iз Z- i N-подiбними вольт-амперними характеристиками, в той час як однофазнi зразки характеризуються лiнiйними залежностями струму вiд прикладеної напруги. Низка аналiтичних методiв рентгенiвської дифрактометрiї, залучених для встанов лення структури включень In6Se7, засвiдчує в них дiю стискувальних напружень, через яку середнi значення розмiру кристалiтiв In6Se7, визначенi за допомогою модифiкованого методу Шеррера, графiчного розмiрно-деформацiйного методу i методу Холдера–Вагнера з точнiстю, кращою нiж 1%, спiвпадають i становлять 26,5 нм. Обговорюються причини неспiвпадiння середнього розмiру нанокристалiтiв In6Se7, визначеного за методом Вiльямсона–Холла (23,13 нм), iз вищезазначеними розмiрами. За допомогою дифракцiйноадсорбцiйного методу знайдено середню масову частку фази In6Se7 в дослiджуваних зразках α-In2Se3 i, вiдповiдно, розраховано середню концентрацiю нанокристалiтiв In6Se7 iз середнiм розмiром 26,5 нм у шаруватiй α-In2Se3. Вбачається перспективнiсть використання композитних зразкiв In2Se3/In6Se7 для роботи в оптичному телекомунiкацiйному дiапазонi довжин хвиль.

(GaxIn1-x)2Se3 films with 0.1 ≤ x ≤ 0.4 were deposited by the thermal evaporation technique. As-deposited (GaxIn1-x)2Se3 films were irradiated using the wideband radiation of a Cu-anode X-ray tube at different exposure times. The spectral dependences of the refractive index and extinction coefficient are measured by the spectral ellipsometry technique. The optical transmission spectra of X-ray irradiated (GaxIn1-x)2Se3 films are studied for various irradiation times. Parameters of the Urbach absorption edge for X-ray-irradiated (GaxIn1-x)2Se3 thin films are determined and compared with those of non-irradiated films. The spectral dependences of the refractive indices of non-irradiated and X-ray-irradiated (GaxIn1-x)2Se3 films are described in the framework of the model developed by Cauchy, Sellmeier, Wemple, and DiDomenico, as well as by the optical-refractometric relation. The detailed variation of the parameters of the Wemple–DiDomenico model for non-irradiated and X-ray-irradiated (GaxIn1-x)2Se3 films has been analyzed. The perspective of applications of (GaxIn1-x)2Se3 films as the materials for optical sensors of X-rays is discussed.
