Using the satellite images for the territory of Ukraine
Authors: Koman M. M. 
Published: December 2020

The purpose of this article is to identify the wind direction and speed using the images from geostationary satellites and through application of two-dimensional wind vectors, the magnitude and direction of which corresponds to the speed and direction of cloud masses, on a satellite image. The results may be used for making a short-term forecast of dangerous weather events within the territory of Ukraine.
To make the technique work, it is necessary to select cloud areas on a satellite image using the threshold method. Then, based on the brightness temperature distribution between two tracking modules (parts of an image based on which two consecutive satellite images are compared), the maximum correlation coefficient for infrared brightness temperature is to be determined. The coefficient corresponds to the movement of cloud masses and sets the beginning and end of the wind direction vector.
To determine the optimum application of the technique for the territory of Ukraine, the analysis of accuracy of tracking modules of different sizes was also performed. The analysis revealed that the accuracy of determining the wind vector direction depends on the tracking module size: the larger it is, the more accurate is the direction vector found, but given that the time interval between images is 15 minutes, the optimum algorithm to be used in Ukraine is the one with 5x5 pixel tracking module.
The technique performance was also compared with the data of ICON and GFS forecast models. The results of the applied algorithm showed that the direction of air masses was more reliable than the data retrieved from the above-mentioned forecast models, because the algorithm analyzes the real-time movement of air masses while the forecast models assess the formation and movement of air masses in advance (with an interval of several hours up to dozens of hours). Numerical wind speed forecast of ICON and GFS models is more accurate, because the algorithm determines the wind speed based on the movement of cloud masses on satellite images whereas the forecast models consider several factors (pressure fields, development and subsequent evolution of cyclones, anticyclones, geographical characteristics etc.) which makes them more realistic.

Published: December 2020

The aim of the study is to determine statistical estimates for the distributions of average monthly and annual temperatures, as well as monthly and annual precipitation for the North-Western Black Sea coast during the climatic change intensification epoch. Parameters of the normal distribution for temperature, two- and three-parametric gamma distribution for precipitation, as well as trend characteristics, are analyzed. To determine the deviation of the values from the previous climatic period, the data of the Climate Cadastre of Ukraine (1961–1990) were used.
The results of the statistical analysis show that steady trend towards an increase in annual air temperatures exists at all stations during the period (2000-2018). In the time course of these characteristics, there is a clearly pronounced separation into two periods with the transition point in 2007. The average monthly air temperatures for the period generally exceed the same values for 1961-1990, and this is especially evident for the summer months.
Time distributions of monthly precipitation are spatially heterogeneous. It was found for Odesa that the maxima are observed in January, July and September, in contrast to other stations, at which the maximum amount of precipitation is registered in the summer months. Also, at the Odesa, the monthly precipitation in most months exceeds the same values for 1961-1990. Annual precipitation during 2000-2018 has a lot of regularities and differences, among which, for example, a common feature is the presence of maxima in 2010. In accordance with the general period trend characteristics, a tendency to an increase in the annual precipitation was found in the very south (Izmail station) only, and it has been especially pronounced since 2009. However, their mean values are lesser than in the Climate Cadastre of Ukraine; this is also observed for the stations Lyubashivka and Mykolaiv. On the contrary, at stations located on the coast (Odesa, Ochakiv), the annual precipitation exceeds of values from the Cadastre.
Based on the analysis carried out, it can be concluded that all persistent tendencies to changes in the values of the considered climatic characteristics are associated with a possible change in the atmospheric circulation over the considered territory.

Background: Vegetable oils recently have been evaluated in many tissues. Pistacia lentiscus (mastic) of the Anacardiaceae family and Sesamum indicum (sesame) of the Pedaliaceae family are conventionally used in the management of gastrointestinal, lung, and skin illnesses. This assay attempts to determine if the oral usage of mastic and sesame oils has any short-term toxic effects in vivo on the rat and evaluate the human anticancer effect in vitro. Materials and Methods: Twenty-one male Sprague-Dewley rats were assigned to three groups randomly: (A) control, (B) mastic oil (400 mg/kg), and (C) sesame oil (2cc/kg). The effects of these oils were investigated by determining histopathological and stereological parameters after six days, and the anticancer effects were evaluated on SW48, HepG2 human cell lines. Results: A mild chronic interstitial inflammation was seen in just one kidney of mastic oil group (B) and the other oneswere normal. In the sesame oil group (C), mild chronic interstitial inflammation was seen in six kidneys. In the liver samples of both groups, there were no specific pathological findings. Different concentrations of mastic oil (0.1%-5%) reduced the cell viability of SW48, HepG2, HEK293t, and human fat cells. Conclusion: Mastic and sesame oils have some side-effects on the kidney and might not be safe at high doses in rats. Sesame oil did not have any toxic effect on HepG2 and HEK293t human cancer cells. Mastic oil treatment has inhibited specific SW48 cells, so this oil seems to be a good adjuvant to chemotherapy in colon treatments.[GMJ.2020;9:e2001]

Estrategias para la toma de decisiones sobre costos en un proceso productivo. Toma de decisiones sobre costos en la pesca del atún
Authors: Fernández Gladys 
Published: December 2020

La contabilidad de costos ha adquirido un papel fundamental dentro de las organizaciones modernas, considerándose una herramienta valiosa en el control y la toma de decisiones estratégicas, utilizando para ello nuevas técnicas, tales como el costeo basado en actividades (ABC) y el enfoque de la cadena de valor, a través de los cuales se controlan las actividades desempeñadas en los procesos y se logra el entendimiento del comportamiento de los costos. En este sentido se seleccionó el proceso de pesca del atún, para identificar las actividades que intervienen en el mismo y diferenciar aquellas que agregan o no valor al producto. Se tomó como muestra un barco atunero, por el método del muestreo aleatorio al azar simple, para garantizar la representatividad de la misma. El estudio se realizó aplicando técnicas de recolección de información, tales como la entrevista y la observación directa. Con la identificación de actividades se espera que la empresa encargada del proceso de pesca del atún pueda realizar un mejor control de estas y alcanzar un nivel de desempeño por Â actividad, a la vez que permita la planificación de las mismas. Se determinó además las actividades que no agregan valor, en las cuales se pueden lograr reducciones de costos.
La politología: Retos y desafíos

Published: December 2020

Â El presente artículo está referido a los retos y desafíos que asume la ciencia política y particularmente el politólogo. Se parte de la idea de que la ciencia política no puede desconocer su diálogo con el resto de las ciencias sociales y su carácter interdisciplinario. Sin embargo, la moderna ciencia política día a día asume con mayor rigor científico y crítica su especificidad, y esto se refleja no sólo en la autonomía que asumen nuestras escuelas y centro de investigación, sino incluso en el quehacer diario asumido por el politólogo. De manera que apoyados en unos conocimientos y herramientas bien fundamentadas (autores, grandes obras, diversos enfoques y perspectivas teórico- metodológicas) los politólogos asumimos los desafíos que actualmente se presentan y se desprenden de la transformación de la política, de sus actores y agencias (concepciones y prácticas) a lo cual se le agregan los desafíos impuestos por el proceso de globalización y las nuevas relaciones y desigualdades, órdenes y actores que surgen a escala mundial, nacional y local.

Background: Alzheimer’s disease (AD) is characterized by the aggregation of two pathological proteins, amyloid-β (Aβ) and tau, leading to neuronal and cognitive dysfunction. Clearance of either Aβ or tau aggregates by immunotherapy has become a potential therapy, as these aggregates are found in the brain ahead of the symptom onset. Given that Aβ and tau independently and cooperatively play critical roles in AD development, AD treatments might require therapeutic approaches to eliminate both aggregates together. Objective: We aimed to discover a chemical drug candidate from natural sources for direct dissociation of both insoluble Aβ and tau aggregates through in vitro assessments. Methods: We isolated four borrelidin chemicals from a saltern-derived halophilic actinomycete strain of rare genus Nocardiopsis and simulated their docking interactions with Aβ fibrils. Then, anti-cytotoxic, anti-Aβ, and anti-tau effects of borrelidins were examined by MTT assays with HT22 hippocampal cell line, thioflavin T assays, and gel electrophoresis. Results: When HT22 cells were exposed to Aβ aggregates, the treatment of borrelidins alleviates the Aβ-induced toxicity. These anti-cytotoxic effects can be derived from the inhibitory functions of borrelidins against the Aβ aggregation as shown in thioflavin T and gel electrophoretic analyses. Among them, especially borrelidin, which exhibits the highest probability of docking, not only dissociates Aβ aggregates but also directly regulates tau aggregation. Conclusion: Borrelidin dissociates insoluble Aβ and tau aggregates together and our findings support the view that it is possible to develop an alternative chemical approach mimicking anti-Aβ or anti-tau immunotherapy for clearance of both aggregates.

Background: The present systematic review and meta-analysis of diagnostic test accuracy summarizes the last three decades in advances on diagnosis of Alzheimer’s disease (AD) in developed and developing countries. Objective: To determine the accuracy of biomarkers in diagnostic tools in AD, for example, cerebrospinal fluid, positron emission tomography (PET), and magnetic resonance imaging (MRI), etc. Methods: The authors searched PubMed for published studies from 1990 to April 2020 on AD diagnostic biomarkers. 84 published studies were pooled and analyzed in this meta-analysis and diagnostic accuracy was compared by summary receiver operating characteristic statistics. Results: Overall, 84 studies met the criteria and were included in a meta-analysis. For EEG, the sensitivity ranged from 67 to 98%, with a median of 80%, 95% CI [75, 91], tau-PET diagnosis sensitivity ranged from 76 to 97%, with a median of 94%, 95% CI [76, 97]; and MRI sensitivity ranged from 41 to 99%, with a median of 84%, 95% CI [81, 87]. Our results showed that tau-PET diagnosis had higher performance as compared to other diagnostic methods in this meta-analysis. Conclusion: Our findings showed an important discrepancy in diagnostic data for AD between developed and developing countries, which can impact global prevalence estimation and management of AD. Also, our analysis found a better performance for the tau-PET diagnostic over other methods to diagnose AD patients, but the expense of tau-PET scan seems to be the limiting factor in the diagnosis of AD in developing countries such as those found in Asia, Africa, and Latin America.
