Published: December 2021

In order to optimize the screw-press extraction conditions of oil from goldenberry (Physalis peruviana L.) seeds obtained from nectar processing waste, a face centered design was applied. The oil was extracted at different temperatures (60, 80, and 100°C) and seed moisture contents (8, 10, and 12%). Oil recovery (OR) increased and residual oil in the cake decreased significantly as moisture content and temperature were reduced; oil moisture and volatile matter as well as acid value, K232, K268, and p-anisidine, respectively, decreased proportionally with the moisture extraction. Thus, the highest OR (86.4%) and the best quality were obtained at 8% moisture content and 60°C pressing temperature. Under these conditions, the extracted oil presented high linoleic acid (76.0%), iodine value (140.0 mg I2/g), and refractive index (1.4769). The oil stability index, measured by Rancimat, varied from 3.65 h (120°C) to 14.87 h (100°C); the predicted shelf life at 25°C was 120.4 days and the activation energy was 85.6 kJ/mol. The results highlighted that screw-pressing of goldenberry seeds provides quality oil without employing polluting and hazardous solvents.

The aims of the present study are to measure and compare dental implant deviations with fully guided and pilot-drill-guided protocols using dynamic navigation systems in polyurethane models. The pilot-drill-guided group was determined to be the study group and included 12 implant applications. In this group, the pilot hole was drilled with navigation guidance, and the procedure was completed freehandedly. In the control group, all the drilling and implant placement steps were performed using the navigation system, and a total of 12 implants were placed. The pre- and postoperative images were compared to calculate the magnitude of implant deviation. The quantitative data of the two groups were compared using the independent-samples t-test and Mann-Whitney U-test. The analyses revealed that the length of the procedure significantly differed between the two groups (p &lt; 0.001). The procedure duration was significantly shorter in the study group. The entry deviation values of the two groups were not significantly different (p = 0.079). The analysis revealed the apex deviation to be higher in the study group than in the control group (p = 0.003). However, the two-dimensional vertical apex deviation values of the implants were not significantly different between groups (p = 0.068). Angular deviation was determined to be significantly higher in the study group (p &lt; 0.001). In the present study, all implants were successfully placed in the models using a dynamic navigation system. The results of this study may be useful for future clinical studies.

Published: December 2021

Purpose. The aim of the work is a comprehensive analysis of the technical and technological parameters of pre-port railway stations in Ukraine as key elements of the port infrastructure, ensuring the interaction of railway transport with seaports. Methodology. In the process of research, the methods of analysis and synthesis were used to study the content and the main provisions of scientific publications on the issues of establishing effective interaction between rail and sea transport, with their subsequent comparison and generalization; methods of statistical analysis for research and systematization of technical equipment of port stations. Results. More than 60% of export cargoes go through Ukrainian ports; while 75% of export volumes are delivered to ports by rail. Currently, due to changes in the conditions for the functioning of the economy and the transport system of Ukraine, there is an imbalance between the capacities of ports and the port railway infrastructure for processing freight flows. Based on the analysis, it was found that the throughput of most stations does not correspond to the prospective, and for some stations - and the actual, volumes of work. In particular, for some stations, the capacity of track development is insufficient; a significant problem is also the low efficiency of the shunting means. An effective way to solve the problem of reducing the imbalance in the processing capacity of ports and the pre-port railway infrastructure is public-private partnership in the implementation of appropriate investment projects, the assessment of which should be carried out using modern scientific approaches. Scientific novelty. The authors have systematized the existing technical equipment of the port stations of Ukraine from the point of view of its sufficiency to ensure the existing and prospective volumes of transportation. Practical significance. The results obtained make it possible to provide a scientific basis for further research into assessing the throughput capacity of pre-port railway stations and the effectiveness of infrastructure projects aimed at increasing it.

El objetivo de este artículo es reflexionar sobre a las infancias en el contexto educativo de la educación infantil; narrar las experiencias que los niños y las niñas tienen en la transición que viven entre la educación inicial, la educación preescolar y el primer grado de básica primaria en escuelas públicas, así como describir los desencuentros, discontinuidades o puntos críticos que se presentan en la articulación entre niveles educativos. Lo que se expone es producto del análisis hermenéutico interpretativo, para rescatar las voces y la experiencia de los sujetos; se recurrió a diversas técnicas como la entrevista en profundidad con maestras y el enfoque mosaico con los niños y niñas/as. La población participante la constituyeron 14 maestras y agentes educativas de ambos niveles, y 17 niños y niñas del grado transición y primero de primaria. Como resultado, se encuentra que la articulación es, por tanto, el eje de análisis que parece advertir una de las crisis frente a la educación de las infancias, la falta de continuidad entre los escenarios educativos; esta representa un punto de quiebre en la progresión de los contenidos, las metodologías y prácticas docentes entre las instituciones; y son estas variables-desencuentros; a los que se ven enfrentados los niños y niñas en sus desplazamientos, y los que influyen directamente en su experiencia escolar.

Концептуальные подходы к осмыслению интеллектуальной собственности в социогуманитарном знании
Authors: Токарева Анастасия Александровна 
Published: December 2021

<p>Статья посвящена анализу изменения подходов к феномену интеллектуальной собственности в социокультурном пространстве. В XXI в. продолжаются процессы перехода от производственной экономики к экономике нематериальной, возрастает значимость обладания нематериальными активами, роль знания и технологий. С Античности и до сегодняшнего дня философы и мыслители разделяют материальный мир вещей и идеальный мир идей, имеющих точки соприкосновения. Такого мнения придерживались Платон, Гегель, а также современные ученые. Такую дуальность возможно перенести на сферу интеллектуальной собственности, включающую в себя как идеальную основу авторство и материальное воплощение идеи. В европейской культуре интеллектуальная собственность получила понимание изначально в правовой сфере. Начиная с XVII в. набирал популярность подход, согласно которому интеллектуальный труд приравнен к труду физическому и автор имеет право на вознаграждение. В результате развития технологий, особенно в XX в., пересматриваются взгляды на интеллектуальный капитал как основной товар в экономике. Правовой характер и экономический характер регулирования интеллектуальной собственности приближаются к собственности материальной. Такая концепция показала противоречия подходов и проблему невозможности однородного регулирования, поставила вопрос внесения множественных оговорок и исключений. В современном мире исследователи приходят к глобальному расширению понимания сферы интеллектуальной собственности как собственности на любую информацию и идею. Таким образом, можно сделать вывод о мультиспециализации интеллектуальной собственности, ее глобальном охвате материальных и идеальных сфер, понимание которой даст необходимый толчок развитию общества.</p>

Major proportion (90.0%) of patients were on TLE regimen, among them (74.4%) were non-adherent. An association was found between health condition of patient, poor life style and adherence rate. Three-month drug dispensation was recommended by most of the participants to improve adherence.Conclusions: Multiple months drug dispension along with other innovative approaches should be tailored made to improve the adherence and compliance among PLHIV individuals.
Vaccine tourism: an emerging topic of discussion
Authors: Shah Anuradha Kunal , Dakshit Kosturi 
Published: December 2021

Vaccine tourism (also known as vaccine vacation) is a term that recently became popular once travel agents started offering tours abroad along with COVID-19vaccination doses as a package in early 2021. Vaccine tourism is a kind of medical tourism where people are offered to get two doses of COVID-19 vaccines, stay in that country, and a tour of that country. It is based on a 3- ‘V’ policy: Visit-Vaccination-Vacation. ‘Vaccine passport’ is a term often confused with vaccine tourism. A vaccine passport is a document of proof that the person has taken a vaccine against that particular disease and is asked to produce it at the point of entry to a different country. This is similar to an immunity passport in which a person is tested for an antibody after a certain duration of taking the vaccine and if the antibody is positive, that means the person is protected against that disease. The history of this goes back to the time when people entering the ‘British Pandharpur' or pilgrims to Mecca for Hajj were asked for a vaccine certificate, a scar of vaccination, or pitted face as a sign of smallpox survival. For COVID-19 WHO has not advised in favor of vaccin

The success of an Endodontic treatment relies on the position and morphology of root canals. It is important for a clinician to be familiar with the canal morphology to negotiate and thereby filling the canals with an inert material. But, the possibility of negotiating the canals with the use of conventional technique alone is difficult. Hence, careful examination with the use of advanced techniques to enhance vision is required to minimize the rate of treatment failures. To compare the efficiency of three methods Cone-Beam computed Tomography (CBCT), clinical analysis, AND Dental Loupes in detecting the MB2 canal in maxillary first molars.One hundred and fifty extracted intact permanent molars were collected. Two examiners i.e., one Endodontist and a Radiologist examined CBCT images of teeth for the number and position of root canals. The first stage included unaided examination using an explorer and K- files. While those teeth that were failed to locate the canals were examined using dental loupes for better magnification. The results were analyzed by McNemar's tests with Bonferroni correction, and Chi-square test using SPSS software v21.Among 150 extracted teeth that were compared,MB2 was detected using CBCT in around 68% of the teeth, while with the use of naked eye and dental loupes, it was found to be around 30% and 66% respectively and the difference in the detection rates was statistically significant.With the view of the parameter under consideration, CBCT has high detection rates followed by dental loupes and naked eye vision.

Magnesium oxide (MgO) nanoparticles due to their antimicrobial properties and ability to survive under harsh conditions have become an area of interest in the field of biomedical sciences. The aim of the study was to evaluate antimicrobial efficacy of Nano-MgO in the elimination of endodontic pathogen . Minimum inhibitory concentration (MIC) of Nano-MgO and sodium hypochlorite against was calculated using broth dilution method. The antibacterial efficacy of Nano-MgO in elimination of the pathogens was seen using an ex-vivo model of decoronated teeth which were experimentally infected. The antibiofilm activity of the tested antimicrobial agents on biofilms was determined quantitatively by counting the colonies on Mueller-Hinton agar plates and by evaluation under scanning electron microscopy (SEM). The data analysis was done using one way ANOVA and the intergroup comparison by student –t test. MIC concentration of Nano-MgO was observed at 10mg/ml for . Mean values of colony forming unit (CFU) count was maximum for normal saline, followed by Nano-MgO and sodium hypochlorite with a significant difference between all the three groups. The results of the study reveal that Nano-MgO has the potential to be used as an alternative irrigating solution in endodontic therapy.

RELATIVISTIC ENERGY APPROACH AND MANY-BODY PERTURBATION THEORY TO COMPUTING ELECTRON-COLLISION CROSS-SECTIONS OF COMPLEX MULTIELECTRON IONS
Authors: Buyadzhi V. 
Published: December 2021

An advanced relativistic energy approach combined with a relativistic many-body perturbation theory with ab initio zeroth approximation is used to calculate the electron-collision excitation cross-sections for complex multielectron systems. The relativistic many-body perturbation theory is used alongside the gauge-invariant scheme to generate an optimal Dirac-Kohn-Sham- Debye-Hückel one-electron representation. The results of relativistic calculation (taking into account the exchange and correlation corrections) of the electron collision cross-sections of excitation for the neon-like ion of the krypton are presented and compared with alternative results calculation on the basis of the R-matrix method in the Breit-Pauli approximation, in the relativistic distorted wave approximation and R- matrix method in combination with Dirac-Fock approximation
THEORETICAL STUDYING EXCITED STATES SPECTRUM OF THE YTTERBIUM WITHIN THE OPTIMIZED RELATIVISTIC MANY-BODY PERTURBATION THEORY

Published: December 2021

Theoretical studying spectrum of the excited states for the ytterbium atom is carried out within the relativistic many-body perturbation theory with ab initio zeroth approximation and generalized relativistic energy approach. The zeroth approximation of the relativistic perturbation theory is provided by the optimized Dirac-Kohn-Sham ones. Optimization has been fulfilled by means of introduction of the parameter to the Kohn-Sham exchange potentials and further minimization of the gauge-non-invariant contributions into radiation width of atomic levels with using relativistic orbital set, generated by the corresponding zeroth approximation Hamiltonian. The obtained theoretical data on energies E and widths W of the ytterbium excited states are compared with alternative theoretical results (the Dirac-Fock, relativistic Hartree-Fock, perturbation theories) and available experimental data. Analysis shows that the theoretical and experimental values ​​of energies are in good agreement with each other, however, the values ​​of widths differ significantly. In our opinion, this fact is explained by insufficiently accurate estimates of the radial integrals, the use of unoptimized bases, and some other approximations of the calculation.
