A Quantitative Study of Tornadoes in South America
Marcos Balicki and Fernando Torena
Parana J. Sci. Educ., v.9, n.7, (12-21), December 1, 2023.
Abstract
This article aims to develop a quantitative study about tornado events in South America, in order to create a database to verify the locations that have suffered the most from the phenomenon and dedicated to the study of the subject. The information for carrying out such research was compiled from articles cited in Google Scholar (or Google Scholar), covering the period from 1985 to 2018. For the search, keywords such as “tornado” (in Portuguese), “tormienta de viento” (in Spanish) and “tornado” (in English). During the survey, the locations (city, country), the number of deaths and injuries, and the estimated speed were noted. Speed was based on the Enhanced Fujita Scale (EF), when this was not described in the body of the text, photos and descriptions of the destruction were analyzed to infer them. The results showed that there was a concentration regarding the phenomenon mainly in the “southeastern region of South America”, and another region comprising Colombia and Venezuela, close to the coast of the Caribbean Sea. Brazil reported the highest number of events in the period (247), while Argentina and Uruguay had the most aggressive events (EF-4). Spring and summer are the most opportune seasons for the development of supercell clouds, similar to what happens in Tornado Alley.

Abstract
Some chemical components involved in grapefruit juice and St. John's wort can produce changes in pharmacological activity of different drugs; however, their interaction with both P-glycoprotein and CyP450 enzyme is not clear. The aim of this study was to evaluate the possible interaction of epoxybergamoti, hyperforin and hypericin with both P-glycoprotein and CyP450 enzyme using 1w0f, 3g5u proteins, midazolam, simvastatin and fexofenadine as theoretical tools in DockingServer program. The results showed differences in the aminoacid residues involved in the interaction of epoxybergamoti, hyperforin and hypericin with 1w0f, 3g5u proteins surface compared with midazolam, simvastatin and fexofenadine. Besides, inhibition (Ki) constant for hyperforin was lower compared with epoxybergamottin and hypericin. Other data, displayed that Ki for epoxybergamottin, hyperforin and hypericin was lower compared with fexofenadine. In conclusion, the results suggest that; 1) hyperforin could act as CyP3A4 inhibitor; 2) epoxybergamottin, hyperforin and hypericin could act as P-glyprotein blocker. This phenomenon suggests that the concomitant use of the chemical components of grapefruit juice and St. John's wort with midazolam, fexofenadine and simvastatin could produce changes in the pharmacological activity of midazolam, simvastatin and fexofenadine.

Approach to the Activities of Closed and Open Societies in which Creativity Prevails
Vladimir Nikolayevich Sukhanov
Parana J. Sci. Educ., v.9, n.7, (35-52), December 1, 2023.
Abstract
A comparison of open and closed societies, their coexistence, complementarity, as well as the directions of their development are presented: a detained society and a reflexive society. The orientation of society towards openness is determined by the orientation of society's participants towards the development of external, still unknown, space: innovation, creativity in all its manifestations, new values, not yet formulated. The participants' perception of the openness and closedness of a society depends on the thinking preferences of these participants: focusing on local values and sources, for a closed society, and turning to external sources, for an open society. The participant’s creative view (his perception) on the openness and closedness of society is presented.

Exploration of the Environmental Policy Subsystem that Impact on Shipbreaking Business in Bangladesh
Mohamamd Yakub and Prabal Barua
Parana J. Sci. Educ., v.9, n.7, (53-66), December 1, 2023.
Abstract
Development and the environment are inextricably linked. Therefore, sustainable practices must be in line with the development efforts. Most developing and impoverished nations opt for an unsustainable practice in order to keep up with rapid development, which results in the highest levels of environmental pollution worldwide. One of the most polluting businesses is ship breaking, which generates hazardous trash during the demolition of an outdated ship. Additionally, the ship-breaking industry has a negative influence on human health that directly affects the workers' food cycle, the soil and intertidal sediments, the physicochemical characteristics of seawater, and most importantly variety. Even with the dangerously high degree of environmental contamination brought on by unforeseen shipbreaking in Bangladesh, little meaningful or practical action is done, and no explicit legislation exists to stop continued pollutants. The issue and its implementations cannot be adequately addressed by the current environmental legislation are also mainly lacking in Bangladesh, the nation most susceptible to climate change. Thus, the current legislation policy policies are insufficiently effective to address shipbreaking's role as a cause of pollution. There should be required for strong collaboration and cooperation among policymakers, scientists, owners, workers, local representatives, NGOs, the media, and other different stakeholders. Sustainable shipbreaking only be possible when the stakeholders are considerable with the others’ perceptions without forfeiting their primary interest.

Пространство-время как физический объект. Завещание Эйнштейна
Валерий Борисович Морозов
Parana J. Sci. Educ., v.9, n.7, (67-71), December 1, 2023.
Abstract
В 1960-е годы физиков волновал вопрос: «Применимы ли уравнения Эйнштейна к большим полям?» В течение последних нескольких лет усердно изучалась литература, в том числе работы самого Эйнштейна, охватывающая период сомнений, прозрений и еще раз сомнений в создании общей теории относительности и реализации сделанного.

Parana J. Sci. Educ., v.9, n.7, (73-81), December 18, 2023.
Abstract
Mangrove forests are highly productive with carbon storage potential almost equal or sometimes more than the terrestrial forest. The net primary production is about 12 tonnes dry wt. ha-1 year-1. This unique forest ecosystem accounts for 3% of carbon sequester by the World tropical forest, and 14% of carbon sequester in the World Ocean. Thus, mangrove forest may become a major player in the domain of carbon trading. The purpose of this study is to estimate the amount of carbon stored and its potential market value in few selected mangrove forests distributed in two sectors of Indian Sundarbans with contrasting variation in salinity. The western sector of Indian Sundarban Biosphere reserve (ISBR) is relatively low saline and promotes luxuriant growth of mangroves, whereas in the central sector exposed to high saline water, the mangroves exhibit stunted growth. Assessment of the monetary values of mangroves in context to mangrove carbon trading considering the Above Ground Biomass (AGB) and Above Ground Carbon (AGC) has been carried out in this research based on the market price of carbon in the voluntary market. The market valuation of the dominant mangrove tree species in the western sector is higher compared to the central sector of ISBR owing to higher AGB and AGC of mangroves in the former sector compared to the later.
