Abstract
New dyes were developed and produced utilizing distinct electron donors (phenothiazine and dibenzofuran), a p-spacer, and an electron acceptor of cyanoacetohydrazide, and their structures were studied using FT-IR and NMR spectroscopy. Following the synthesis of dye molecules, the photophysical and photovoltaic characteristics were investigated using experimental and theoretical methods. The photosensitizers have been exposed to electrochemical and optical property experiments in order to study their absorption performance and also molecular orbital energies. The monochromatic optical conversion efficiency of (Z)-N-((5-(10H-phenothiazin-2-yl)furan-2-yl)methylene)-2-cyanoacetohydrazide (PFCH) found higher than that of (Z)-2-cyano-N'-((5-(dibenzo[b,d]furan-4-yl)furan-2-yl)methylene)acetohydrazide (BFCH), with IPCEs of 58 and 64% for BFCH and PFCH, respectively. According to the photosensitizer molecular energy level diagram, the studied dye molecules have strong thermodynamically advantageous ground and excited state oxidation potentials for electron injection into the conduction band of titanium oxide. It was observed that the ability to attract electrons correlated favorably with molecular orbital energy. While density functional theory calculations were used to examine molecule geometries, vertical electronic excitations, and frontier molecular orbitals, experimental and computed results were consistent. Natural bond orbital and nonlinear optical properties were also calculated and discussed.

Abstract
Background: The aim of the current study was to evaluate and compare the influence of Dycal, Lime-lite, Theracal LC, Biodentine, Resin-modified glass ionomer cement (RMGIC), and Activa Bioactive as the pulp capping material on the shear bond strength of resin composite to dentin.Methods: A total of 70 extracted caries-free molars were randomly assigned to seven groups. Six test groups were covered with various protective liners: Dycal (GD), Theracal LC (GT), lime-lite (GL), Activa Bioactive (GA), Biodentine (GB), RMGIC (GR). The control group (GC)received no liner pretreatment. Each sample was bonded to resin composite using the total-etch tetric N bond adhesive. The samples were then tested for shear bond strength using the universal testing machine at a cross-head speed of 1 mm/min until bond failure occurred. The data were analyzed using the one-way ANOVA test followed by the Tamhane post-hoc test for pairwise comparisons of the groupsResults: Independent of the type of the applied liner, all groups exhibited inferior SBS to dentine compared to the control group. GT and GR showed significantly higher shear bond strength than GB and GD, which showed the lowest shear bond strength. GL and GA also had significantly lower SBS results than GT. The mode of fracture was predominantly cohesive in GD, GB, and GT and adhesive in GA.Conclusion: This present study concludes that the bond strength of resin-composite to dentine can be affected differently using various types of liners.

The aim of this study: was determine the force of tension and deformation of axillary nerve in rupture rotator cuff and paresis of deltoid muscle of the shoulder joint.
Material and methods: Semi-natural modelling based on the axial scans spiral computed tomography of the intact shoulder joint was performed to determine the degree of traction load on the axillary nerve with distal displacement shoulder head and tendon rupture which paresis of the deltoid muscle.
Result: The values of deformations for axillary nerve being at the limit of tissue strength at distal displacement of humeral head of the model by 50 %, progressively increased with increasing distal displacement of humeral head to 100 % of its diameter, reaching values 1.7 times higher than the strength nervous tissue.
Conclusion: The progressive changes occurring in the axillary nerve under the action of traction loads, and as a consequence of its ischemia, over time can lead not only to demyelination, but also to the defeat of the axons themselves atrophy of its fibers. In turn, deltoid muscle atrophy increases the traction load on the affected axillary nerve, which forms a vicious circle. The only possible option to "break" the vicious circle is restore the stabilizing structures damaged during the injury, among which one of the most important is the tendons of the rotator cuff of the shoulder. Surgical restoration of the integrity rotator cuff of the shoulder reduces the traction load acting on the axillary nerve, which in turn significantly improves the conditions for reinnervation of the deltoid muscle.

The aim of the research – assessment of vestibular function in children with acute purulent otitis media by computer static stabilometry compared with typically developed children of the same age.
Materials and methods: 22 children with purulent otitis media aged 4 to 7 years and 30 practically healthy peers were examined by static stabilometry on the device “MPFI stabilograph 1” (Kharkiv, Ukraine). Indicators of variation and shape of the pressure center distribution, spectral-correlation indicators of stabilograms, as well as integral indicators of stability (length, velocity and angle of postural oscillations) were taken into account and the equilibrium functions of the two sensory states (open and closed eyes) are calculated in the StabiliS software.
Results: purulent otitis media causes posterior displacement of the absolute coordinates of the pressure center. In the state with closed eyes, children with purulent otitis differ from their healthy coevals by 14 of 24 stabilometric parameters, including stabilogram length, speed, angle and amplitude of oscillations, giving way to them in the stability of equilibrium. Children with purulent otitis media are more sensitive to the visual canal of postural control than their coevals. Involvement of visual afferents in postural control significantly improves balance maintenance in children with purulent otitis by reducing deviations of postural oscillations, which is reflected in the probable changes of 9 out of 24 stabilometric parameters compared to control.
Conclusions: In preschool age, purulent otitis media leads to latent vestibular dysfunction, which is manifested by a violation of the stability of the vertical posture in a state with closed eyes and is compensated by visual-vestibulo-proprioceptive integration in the process of postural control.

For use in veterinary medicine for the treatment of the wound process and the prevention of mastitis, the composition and technology of an emulsion-based cream, conventionally called “Saprocream”, has been developed. Clinical trial of the drug “Saprocream” proved its effectiveness and safety for use in the healing of microtraumas, erosions and cracks (wounds) of the udders of cows.
The aim of the research were was the standardization of the cream under the conventional name “Saprocream” for use in veterinary medicine as a wound healing agent, the development of methods of identification and quantification and their validation.
Materials and methods. Test samples of emulsion cream type o / v, containing 15 % aqueous extract of sapropel (VES), 10 % oil extract of sapropel (OES), 6 % emulsifier No. 1, 1 % cetylstearyl alcohol, preservatives – 0.01 % nisin, 0.1 % euxil K 100 and purified water up to 100 g were made by phase inversion.
The methods of pharmacopoeial articles of the European Pharmacopoeia of the 10th edition, SPhU 1.0, as well as industry standards were used to develop methods for identification and quantification of active pharmaceutical ingredients (API) in the developed cream and its standardization.
Results. The chromatographic profile of the acetone extract from the cream coincides with the chromatographic profile of the reference solution ((PRS) β-carotene), which indicates the presence of substances of carotenoid structure. The absorption spectrum of hexane extraction from the cream in the range from 500 nm to 750 nm has a maximum absorption at a wavelength of 670±2 nm, which coincides with the maximum absorption of hexane solution OES, indicating the presence of chlorophyll.
A method for quantifying the total mass fraction of humic acids (HA) has been developed and it has been established that the total mass fraction of HA in cream samples with sapropel extracts is 0.828 %.
The results of the validation of the method show that there is a linear relationship between the concentration of the total mass fraction of HA and the mass of the AES sample with a correlation coefficient of 0.9981 (³ 0.9981). The developed technique is precise, because the value of the relative confidence interval is less than the critical value for the convergence of the results: D %=1.34≤1.60 and the criterion of insignificance of systematic error d=0.51 is fulfilled.
Conclusions. An emulsion-based cream under the conventional name “Saprocream” has been standardized, methods for identification and quantification of active substances have been developed and validation of the developed methods for use in veterinary medicine as a wound-healing and anti-inflammatory agent has been carried out.

Authors: Herasymova Oksana 
Published: December 2021

The aim: to improve the early diagnosis of cardiac arrhythmias and conduction disorders in children with gastroesophageal reflux, by studying the prognostic significance of the life history in this group of patients.
Materials and methods. 56 children aged 8 to 18 years, mean age 14,93±2,62 years were examined. All examined children were divided into two alternative groups: Group I (main) was represented by 28 children with gastroesophageal reflux in combination with cardiac arrhythmias and conduction disorders, and Group II (control) - 28 children with only gastroesophageal reflux without cardiac arrhythmias and conduction disorders. Patients underwent clinical, anamnestic (with a detailed study of life history) and instrumental studies (electrocardiography, Holter daily ECG monitoring, esophagogastroduodenoscopy).
Results. When analyzing the prognostic significance of the patient's life history, it was found that its very high level was observed for the number of foci of chronic infection (I=6.0) and the frequent incidence of a child up to year old of life (I=3.05).
High prognostic value was registered relative to the number of diseases suffered by the child per year on average (I=2.35), and moderate predictor properties are characteristic of chickenpox (I=0.89) and the number of chronic diseases at present (I=0.71).
The duration of breastfeeding showed low (I=0.30) prognostic significance.
Suffered previously bacterial infections did not have predictor properties (I=0.12). In general, the prognostic significance of the patient's life history was high (I̅=2.20).
Conclusions. It was found that in general the prognostic significance of the patient's life history was high (I̅=2.20)
It is determined that in favour of the development of cardiac arrhythmias and conduction disorders evidence: the number of foci of chronic infection ≥1-2; lack of frequent morbidity in a child up to a year of life; the number of diseases suffered per year ≤5; the presence in past medical history of chickenpox; the number of chronic diseases in a child at present ≤2 and short-term (≤9 months) breastfeeding.
It has been established what denies probability of development of the researched pathology: absence of the centers of a chronic infection; the presence frequent incidence of a child up to year old of life; the number of diseases suffered per year≥6, and chronic diseases at present ≥3; longer (≥9 months) breastfeeding and no history of chickenpox

Abstract
Given that long-term treated wastewater discharge may alter the microbial community of the recipient coast, it is important to evaluate whether and how the community's stability is impacted. We constructed microcosms using coastal sediments with (near-coast) and without (far-coast) a wastewater disposal history and compared the communities’ responses to p-chloroaniline (PCAN, a typical organic pollutant) in low (10 mg/L) and high (100 mg/L) concentrations. Compared to the far-coast community, the near-coast community drove faster PCAN attenuation and nitrate generation. More significant negative correlations were observed between the alpha-diversity indices and PCAN concentrations in the far-coast communities than the near-coast ones. The community turnover rate, represented by the slopes of the time–decay curves, was slower for the near-coast community (−0.187) than that for the far-coast community (−0.233), but only when the PCAN was added in low concentration. Our study revealed that the long-term wastewater disposal may cause the sediment bacterial community to be less sensitive and more stable in response to a future disturbance, demonstrating a significant historical effect of environmental context on the coastal microbial community's stability.

Published: December 2021

Abstract
Carbonate bedrock regions represent that 14% of Earth's continental surface and carbon (C) sink in karst water plays an important role in the global C cycle due to the CO2 consumption during carbonate mineral weathering. Intensive agriculture and urbanization have led to the excessive input of nitrogen (N) into aquatic systems, while the high concentrations of inorganic C in the karst water might affect the N cycle. This paper summarized the characteristics of water in karst regions and discussed the N transformation coupled with the C cycle in the condition of high Ca2+ content, high pH, and high C/N ratios. Carbonates can consume more atmospheric and pedologic CO2 than non-carbonates because of their high solubility and high rate of dissolution, resulting in the higher average CO2 sink in karst basins worldwide than that in non-karst basins. Therefore, carbonate mineral weathering and aquatic photosynthesis are the two dominant ways of CO2 absorption, which are termed as coupled carbonate weathering. As the alkalinity and high C/N content of karst water inhibit the denitrification and mineralization processes, the karst aquatic environment is also served as the N sink.
O CONTROLE CONCENTRADO DE CONSTITUCIONALIDADE E A DEFESA DE INTERESSES CORPORATIVOS: análise das ADIs no período de 2013 a 10 de novembro de 2015
Authors: UFRN PPGD 
Published: December 2021

O controle de constitucionalidade vem sendo justificado no meio acadêmico como meio a garantir os direitos das minorias contra interesses das maiorias expressas em leis violadoras de direitos fundamentais, porém, atualmente, as decisões proferidas pelo STF, em sede de controle concentrado de constitucionalidade, não vêm guardando correspondência com a teoria garantidora mencionada, pois repercutem interesses corporativos de grupos privilegiados, por vezes alheios aos direitos fundamentais. Identificado o problema, partiu-se para a hipótese de que o atual desenho constitucional dirigido ao controle de constitucionalidade promove e está direcionado, de fato, a proteção de direitos corporativistas e, tal fato, repercute nas decisões proferidas pelo STF. Para desenvolver a hipótese foram realizados estudos bibliográficos sobre o tema, inicialmente descrendo a origem das matrizes do controle de constitucionalidade e seu desenvolvimento no Brasil, passando a apresentação das teorias procedimentalistas e substancialistas do controle de constitucionalidade e as espécies de ações diretas dirigidas ao STF no controle concentrado e abstrato de Leis ou atos normativos. Com o objetivo de avaliar a hipótese também foram levantados e analisados dados informativos contidos no site oficial do STF no período compreendido entre 2013 a 10 de novembro de 2015, sendo, ao final, confirmado que, hoje, o desenho do controle concentrado de constitucionalidade serve a interesses corporativistas de grupos determinados.

Published: December 2021

Objetiva-se no presente artigo delinear traços que colaborem com a construção de uma metodologia não adversarial de “resolução” de conflitos fundiários urbanos. Assim, pretende-se avaliar a possibilidade de aplicação aos conflitos fundiários urbanos pátrios do sistema de resolução baseado no diálogo entre as partes envolvidas na disputa. Este método, denominado Establishing Neighbourhood Dialogue, foi elaborado e aplicado pela Rede da União Européia para Implementação e Execução da Legislação Ambiental (European Union Network for the Implemention and Enforcement of Envioronmental Law – IMPEL Network), para conflitos entre empresas e sua vizinhança, com relação a impactos ambientais decorrentes da atividade produtiva. Todavia, previamente serão apresentadas considerações e perspectivas tipológicas quanto aos conflitos fundiários urbanos, para que a partir dos traços e vozes destes conflitos se possa ponderar quanto ao conjunto de estratégias para construção de diálogos.

RESUMO
O presente trabalho visa investigar como a política de comércio internacional brasileira relaciona-se com os objetivos da Agenda 2030 para Desenvolvimento Sustentável da ONU, especialmente o Objetivo 17. Fortalecer os meios de implementação e revitalizar a parceria global para o desenvolvimento sustentável. Para tanto, a partir de revisão bibliográfica, far-se-á a análise do papel das instituições de comércio internacional como mecanismo garantidor e promotor do direito e desenvolvimento, apoiado na teoria de aumento das liberdades substantivas, do professor indiano Amartya Sen. Traçadas essas premissas, investigar-se-á o direito positivo brasileiro para delinear suas estruturas institucionais e seu alinhamento, ou não, com as boas práticas de cooperação internacional, com enfoque nas práticas comerciais internacionais. Por fim, realizar-se-á uma crítica ao modelo institucional traçado pela política de comércio internacional brasileira e uma proposta de adequação para que se alcance os objetivos assinalados pela ONU.
