Comparison of signs of choroidal melanoma spreading into the retina according to optical coherenct tomography and pathomorphological studies
Authors: Stoyukhina A. S. , Nechesnyuk S. Yu. 
Published: July 2022

The most common factors determining the unfavorable choroidal melanoma (CM) prognosis are: patient's advanced age, tumor size, epithelioid histotype, developed vascularization and extrascleral tumor extension. Also, there are indications ofan unfavorable vital prognosis when hemorrhages appear in the tumor area. There are suggestions that retinal changes detected by optical coherence tomography (OCT) are comparable to the results of morphological studies, and the structure of the choroid determined by EDI-OCT (enhanced depth imaging) matches its morphological structure. Purpose: to assess the possibility of in vivo detection of morphological signs of CMspreading into the retina according to OCT data. Materials and methods. 5 CM patients aged 55.20 ± 10.57 who subsequently underwent primary enucleation, were tested by OCT that showed the maximum CM elevation of 4.85 ± 1.76 mm, and the maximum diameter of13.09 ± 4.14 mm. Results. The correlation of tomographic and histological picture was obtained in the following signs: destruction of Bruch's membrane, presence of hyperreflective changes at the level of retinal pigment epithelium (deposits and extended areas of its thickening), photoreceptors changes, neuroepithelial detachment, the intraretinal cavities. A partial correlation took place for signs of subretinal transudate and infiltration of the outer layers of the retina. No correlation was obtained for the signs of infiltration of inner retina layers and the inner limiting membrane rupture with CM dissemination on a retinal surface. The cases of divergent interpretation between OCT and morphological studies are as­ sociated with the presence of fibrosis foci due to a formation of superficial tumor necrosis and foci of proliferation of the pigment epithelium with its dissemination into the inner retina layers. Conclusion. Comparison of OCT signs ofM C with pathomorphological data obtained from 5 enucleated eyes made it possible to expand the interpretation of OCT signs of CM spreading beyond the Bruch's membrane with the forma­tion of tumor growth zones in the retina.

Abstract
Identifying and demarcating watershed areas provides a basis for designing and planning for water resources. In this study, DEMs-based estimates of watershed characteristics of three rivers of Bangladesh – Halda, Sangu, and Chengi – were derived using eight Digital Elevation Models (DEMs) of 30 m, 90 m, and 225 m resolution in the Soil and Water Assessment Tool (SWAT). We have assessed watershed characteristics concerning DEMs, resolutions, and Area Threshold Values (ATVs). Though the elevation data differed, high correlation values among DEMs and resolutions confirm the negligible effect of elevation in the watershed delineation. However, the slope and watershed delineation vary for different DEMs and resolutions. The 90 m DEMs estimated larger areas for Halda and Chengi and lower perimeter values for all three rivers. In watershed delineation, the area near the mouth and flat terrain did not coincide with DEMs. The common intersected area by DEMs can be used as the focal area of watershed management. ATV ≤ 40 km2 significantly influences sub-basin counts and stream network extraction for these watershed areas. Though watershed size and shape were independent of the different ATVs, the DEM-based watershed delineation process in SWAT needs optimum ATV values to represent the stream network precisely.
A novel sulfur-driven autotrophic denitrification coupled with bio-cathode system for bioelectricity generation and groundwater remediation

Published: July 2022

Abstract
This study explored the feasibility of treating wastewater using sulfur-driven autotrophic denitrification (SAD) coupled with the bio-cathode of microbial fuel cell (MFC), focusing on simultaneous bioelectricity generation, denitrification, and desulphurization. A maximum output voltage of 360 mV was obtained with a power generation cycle of 25 h when simulated wastewater with 100.0 mg/L of each -N and S2−-S was employed as the influent in the SAD-BMFC. Compared with solo SAD or MFC, SAD-BMFC obtained a higher -N removal rate (E12 h = 87.7%, E24 h = 100%), and less -N accumulation. S2−-S of the influent was almost completely removed, oxidized to S0-S (88.6–90.2 mg/L) and -S (9.8–11.4 mg/L). The reaction system achieved self-balance of acidity-alkalinity (pH 7.05–7.35). The SAD process was the main pathway for -N removal (80.2%) and a smaller proportion of electrons came from the bio-cathode. This study effectively combined SAD with a bio-cathode system for simultaneous energy harvest and bio-enhanced remediation of groundwater contaminated by both -N and S2−-S.

Abstract
Sulfidated nano zero-valent iron supported by activated carbon (S-nZVI/AC) composites were synthesized via liquid phase reduction method, and then they were used for Cr(VI) elimination. Characterization results showed that Fe0 was the main component, besides, iron oxides and iron sulfides were also detected. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) results showed that S-nZVI nanoparticles were homogeneously distributed on the surfaces of AC. The influences of S/Fe ratio, C/Fe ratio, pH value, reaction temperature and co-existed ions (Cl−, SO42−, PO43− and NO3−) on Cr(VI) removal performances were investigated. Furthermore, the corresponding mechanisms were also discussed. The S-nZVI/AC composites exhibited good aging-resistance performances that Cr(VI) removal efficiency still maintained at 83.1% after being sealed in water for seven days, and they also had satisfying cycling stabilities that Cr(VI) removal efficiency only decreased less than 10% after four cycles. The good performances of S-nZVI/AC composites for Cr(VI) removal are attributed to the protection effect of iron sulfides and immobilization effect of AC, making S-nZVI/AC as a promising candidate for Cr(VI) elimination in effluents.
О балансе между сохранением и модернизацией архитектурно-градостроительного наследия
Authors: Бондаренко Игорь 
Published: July 2022

До сих пор не вполне ясны причины возникновения острой конфликтной ситуации между защитниками архитек­турного наследия и сторонниками модернизации городов. И те и другие апеллируют к историческому опыту. Действи­тельно, была традиция поддержания преемственности, но известна и другая традиция, согласно которой уничтожать старое и создавать на его месте новое считалось делом нуж­ным и прогрессивным. Возникает парадоксальный вывод о том, что охрана наследия требует разрушения одного из устоев традиционной культуры. В данной статье предлагается рассматривать обозначенную проблему, исходя из призна­ния исторически беспрецедентной новизны сложившейся культурной парадигмы. Анализ отношения к сбережению и обновлению старых построек и планировок в исторической ретроспективе приводит автора к заключению о том, что в Новое и Новейшее время новаторские устремления стали чрезмерными, агрессивными, сокрушительно-революци­онными. Сегодня настало время отказа от радикального обновления исторического наследия, признанного невоз­обновляемым культурным ресурсом. Архитектурные новации обязаны быть априори деликатными по отношению к нему и иметь пространственную обособленность. Только при таком условии становится возможным возвращение к умеренной, естественной и жизнеспособной концепции устойчивого, бесконфликтного развития среды жизнедеятельности.

Published: July 2022

В данной статье отражены результаты рассмотрения проблем математического моделирования сейсмической безопасности десятиэтажного здания с основанием в виде упругой полуплоскости при нестационарных волновых воздействиях. Проблема моделирования задач переходного периода связана с условием Куранта-Фридрихса-Леви и является актуальной фундаментальной и прикладной научной задачей. Разработаны алгоритм и комплекс программ для решения ли-нейных плоских двумерных задач. При разработке комплекса программ использовался алгоритмический язык Фортран-90. Получена явная двухслойная конечноэлементная схема.Для оценки достоверности азработанной методики, алгоритма и комплекса программ была решена задача о воздействии импульса в виде трёх полупериодов синусоидына упругую полуплоскость. Решается система уравнений с 8016008-ю неизвестными.Рассматривается задача о воздействии плоской продольной упругой волны в виде функции Хевисайда на десятиэтажное здание с основанием. Решается система уравнений с 16202276-ю неизвестными. В характерных областях исследуемой задачи получены контурные напряжения и компоненты тензора напряжений. На основании проведённых исследований можно сделать следующие выводы: упругие контурные напряжения на гранях здания являются почти зеркальным отражением друг друга, то есть антисимметричным; при сейсмическом воздействии в основном преобладают изгибные волны.
Streptococcus canis sequence type 43 may be associated with treatment failure in dogs with corneal ulceration
Authors: Leis Marina L. , Sandmeyer Lynne S. , Costa Matheus O. 
Published: July 2022

Abstract

OBJECTIVE
To profile Streptococcus canis isolates obtained from corneal ulcers in dogs.

ANIMALS
10 dogs.

PROCEDURES
Medical records were searched to identify dogs diagnosed with ulcerative keratitis by a veterinary ophthalmologist and having a positive corneal culture for S canis during the year 2020. For each case, clinical findings and outcome were determined, antimicrobial resistance and sensitivity panels were summarized, whole genome sequencing was performed, and isolates were typed using multi-locus sequence typing and genome-based proteome phylogenetic analysis.

RESULTS
10 S canis isolates were included from dogs diagnosed with ulcerative keratitis. Dogs were either treated surgically via keratectomy and conjunctival grafting (n = 6) or treated medically (4). Three of 10 corneas failed to heal and required enucleation (2/6 conjunctival grafts and 1/4 medically managed corneal ulcers). All three corneal ulcers that failed to heal were associated with S canis sequence type (ST) 43. Sequence types identified from successfully treated cases included ST8 (n = 1), ST50 (1), ST2 (2), ST27 (1), and ST15 (1). One ST43 isolate was obtained from a dog that healed following a conjunctival graft, however this was the only dog that received an oral antibiotic in addition to topical antibiotics.

CLINICAL RELEVANCE
Based on this small dataset, S canis ST43 may be associated with increased virulence and contribute to conjunctival graft failure and progressive corneal collagenolysis. The postoperative administration of an oral antimicrobial may protect against conjunctival graft rejection in dogs specifically due to S canis ST43.

Published: July 2022

Abstract
In this study, Mn doped CdS/ZnO nanocomposites synthesized by co-precipitation method and its photocatalytic activity was tested using methylene blue under solar light irradiation. The prepared hybrid nanocomposites are characterized by using different physicochemical techniques including XRD, FESEM, EDX, TEM, UV-vis DRS and PL analysis. From the XRD analysis, Mn doped ZnO/CdS nanocomposite diffraction peaks only reflect the binary crystalline structures of ZnO and CdS. However, there is no characteristic peak of Mn is found that may be because of low content of Mn doped on ZnO/CdS. But Mn (2.9 wt%) was detected in the Mn doped ZnO/CdS nanocomposite, which was measured by EDX analysis. The FESEM and TEM results exhibit the surface particle of Mn doped ZnO/CdS nanocomposite which have spherical nature and confirmed the formation of Mn doped ZnO/CdS nanocomposites. The photocatalytic degradation results have revealed that the Mn doped CdS/ZnO nanocomposites exhibit admirable activity toward the photocatalytic degradation of the MB. The reason for excellent photocatalytic activity of Mn doped CdS/ZnO nanocomposites indicates the absorbance band shifted to red region and reduction of recombination of photogenerated electron-hole, which is in good agreement with UV-visible DRS analysis and PL study results. The fitted kinetic plots showed a pseudo-first-order reaction model and the appropriate rate constants were found to be 0.0068 min−1, 0.00846 min−1, and 0.0188 min−1, for ZnO, 25 % CdS/ZnO, and 0.8 mol% Mn doped CdS/ZnO nanocomposites, respectively. The maximum photocatalytic activity was achieved by 0.8 mol% Mn doped CdS/ZnO nanocomposites with a 95% degradation efficiency of MB. Hydroxyl and superoxide radicals, having a vital role in the degradation of MB, confirmed scavenging experiments. In addition, the recycling tests displays that the Mn doped CdS/ZnO nanocomposites have shown good stability and long durability. The enhanced photodegradation activity of Mn doped CdS/ZnO nanocomposites indicates the potential of the nanocomposite for the treatment of organic pollutants from the textile wastewater.

Published: July 2022

AbstractPier abutment is defined as a freestanding abutment with edentulous space on both sides. This case report described the rehabilitation of a patient who presented to the department with the primary complaint of missing teeth and difficulty in mastication. Intraoral examination revealed missing right maxillary canine and the second premolar, with the lone standing first premolar acting as a pier abutment. To reduce the stress transferred to the abutment and prosthetic assembly, a non-rigid (Tenon-mortise) connector was used in the case, with a keyway (mortise) distal to the pier abutment and a key (Tenon) mesial to the distal pontic.

Authors: Costa Diogo António da Silva , Mamede Henrique São , Mira da Silva Miguel 
Published: July 2022

AbstractRobotic process automation (RPA) is a recent technology that has recently become increasingly adopted by companies as a solution for employees to focus on higher complexity and more valuable tasks while delegating routine, monotonous and rule-based tasks to their digital colleagues. The increased interest, reflected in the increasing number of articles regarding approaches and test cases, has triggered the necessity for a summary that could extract the more generalisable ideas and concepts about these software robots. This paper used a Systematic Literature Review (SLR) approach to find and synthesise information from articles obtained on this subject. This research identified the most general implementation approaches of successful RPA adoption cases, observed benefits, challenges commonly faced by organisations, characteristics that make processes more suitable for RPA, and research gaps in the current literature. The findings presented in this paper have two purposes. The first is to provide a way for companies and organisations to become more familiar with good practices regarding the adoption of robotic process automation. The second is to foster further research on the subject by complementing the current knowledge and proposing new paths for research.

Authors: Bieńkowska Agnieszka , Koszela Anna , Ludwikowska Kamila , Tworek Katarzyna 
Published: July 2022

Abstract
Job performance is an extremely complex factor affecting organisational performance. The literature recognises factors impacting job performance positively and negatively. This article aims to verify the turnover-mitigating effect on the relationship between servant leadership and job performance. The developed moderated mediation model is empirically verified based on the data collected from 263 managers working in Poland’s for-profit organisations. The results were analysed using Macro for IBM SPSS Statistics. It has been shown that employee turnover is a mediator in the job performance model based on turnover-mitigating servant leadership. Additionally, the influence of employees’ dynamic capabilities has been analysed. The study revealed the significance of servant leadership in influencing job performance and the disruptive relationship between employee turnover and the impact of employees’ dynamic capabilities in reducing employee turnover. This research provides practical implications for managers and organisations regarding selecting the right leadership style to improve employee job performance.

Published: July 2022

Background:
Ankylosing spondylitis (AS) is a chronic, progressive, inflammatory disease of the spine and SI joints. Diagnostic criteria and treatments have continued to evolve, necessitating a historical compendium of AS and its management. This paper aims to review the historical context underlying the discovery of AS, as well as the major diagnostic and therapeutic discoveries in the last two centuries.

Methods:
A scoping review of the literature pertaining to AS was performed via the Pubmed, Scopus, and Web of Science databases. Future directions of AS treatments were assessed by querying the clinicaltrials.gov website.

Results:
The history of AS can be traced as far back as ancient Egypt (as evidenced by the discovery of its presence in ancient Egyptian mummies) to the late 20th century, when the inherited nature of AS was linked to a genetic factor, HLA-B27. Each discovery made throughout the years led to further investigations into the pathophysiology, diagnosis, and treatment of AS. The criteria to differentiate AS from rheumatoid arthritis were first reported in 1893. Since then, diagnostic criteria for AS have undergone a series of changes before the present-day diagnostic criteria for AS were ultimately determined in 2009 by the Assessment of Spondyloarthritis International Society.

Conclusion:
As the pathophysiology of AS is better understood, healthcare providers are able to diagnose and treat the condition more effectively. In particular, earlier diagnosis and multiple treatment options have facilitated efficient and more effective treatment.
Serum magnesium levels in chronic kidney disease patients

Published: July 2022

Objectives:
Chronic kidney disease (CKD) is a condition of life-threatening nature presenting with deterioration in kidney function which is both irreversible and progressive. It is characterized by progressive incapability of the kidneys to filter the excretory products of blood consequently necessitating dialysis to prevent azotemia, end-organ damage, and ultimately death. The role of the kidneys in the homeostasis of magnesium and conservation of this neglection ion’s concentration in blood is undeniable. The objective of the present study was to estimate serum magnesium in CKD subjects and healthy control groups.

Material and Methods:
Serum creatinine, eGFR, Serum magnesium was assesed in 37 CKD patients and 43 healthy controls.

Results:
The serum creatinine levels were significantly higher (P < 0.001) in cases (2.4 ± 0.88 [mg/dL]) when compared to healthy controls (0.85 ± 0.1 [mg/dL]) [Table 1]. The estimated GFR was calculated using the Modification of Diet in Renal Disease formula and was 31.2 ± 12.1 mL/min in cases and 85.67 ± 13.1 mL/min in controls and they were significantly different (P < 0.001). Serum magnesium was 2.02 ± 0.36 mg/dL in cases and 2.01 ± 0.17 mg/dL in controls.

Conclusion:
The overall distribution showed a trend of hypomagnesemia in CKD patients but it was not statistically significant (P = 0.877). In our study, though statistically trivial, we found a trend toward hypomagnesemia in CKD patients when compared to controls. The lack of significance could be because the CKD patients were not grouped according to stages. A larger study with proper categorization and exclusion can provide us with better insights into magnesium dynamics in CKD patients.
