COVID-19 pandemic’s broadcast media messages’ consumption in rural community and behavioral change
Authors: Ngonso Blessed Frederick , Chukwu Obinna Johnkennedy 
Published: February 2021

This study adopts FGDs as a research method. The discussion process was conducted in four different quarters that make up the community with 25 participants. Four research questions were formulated to guide the course of investigation. The findings of the study showed that a large portion of the community members are exposed to media messages on COVID-19 through the television. The findings also showed that, the community people particularly the educated ones watch TV on cable (GOTV and Startimes) and these are the people who shared information with family members, interpret it and take positive actions. While those who cannot read or write watch local NTA Auchi. These group of persons are few and mainly among the illiterate who source for news in local language. A smaller proportion of the sample also affirmed that they do not watch TV or listen to radio for COVID-19 information due to hunger. This group maintained that they only watch Zee World channel. The findings also showed that no group talked about radio with emphasis. It is therefore, agreed that the rural community people in Iyamho do not depend on radio for information including COVID-19 information. In conclusion, the researchers agreed that rural dwellers of Iyamho are exposed to COVID-19 information on TV and the information has shaped their behavior by their interpretation of the messages received. The researchers also conclude that, radio is no longer fashionable in the rural community. It is therefore, recommended that subsequent studies on rural dwellers media message consumption should painstakingly interrogate the influence of social media. Again, in the future, if there is need for health awareness campaign, the government and health agencies should consider the use of traditional media to pass the information across to rural dwellers since illiterate folks still exit in the rural communities. TV information on health matters should be translated in rural languages on TV stations that are on GOTV and Startimes cables.
Postharvest responses of Carnation cut flowers to Prunus cerasoides mediated silver nanoparticles
Authors: Le Tu Thi Anh 
Published: February 2021

Introduction: The procedure to synthesize silver nanoparticles (SNPs) from Prunus cerasoides leaf extract and their effect on vase life and flower quality of cut carnation were investigated.
Methods: SNPs were bio-synthesized from Prunus cerasoides leaf extract and characterized by using UV-Vis technique, TEM, and SEM images. The postharvest responses of carnation cut flowers to the biosynthesis SNPs were evaluated through vase life, relative fresh weight, vase solution uptake, flower diameter of cut carnation.
Results: SNPs were synthesized under optimum conditions, including using the extract of leaf heating at 60 oC in 30 min, 4 mM of silver nitrate, pH of 11, and 180 min of reaction time. SNPs exhibited antimicrobial activity and then alleviated the bacterial development in the preservative solution. All treatments with SNPs had improved the vase life and quality of cut carnation compared to the control. A vase solution containing 2% sucrose enhanced the carnation cut flowers.
Conclusions: The preservative solution containing 25 ppm SNPs and 2% sucrose showed the best effect. SNPs could be used as a promising antibacterial agent applied in the preservative solution for cut carnation flowers.
Development of digestive organs in goslings raised for meat, depending on lithium level in mixed feeds

Published: February 2021

Recently, the vital necessity of lithium for living organisms has been experimentally proven and also it was previously considered as a conditionally essential trace element. Numerous experimental research conducted on various animals and poultry types have revealed quite wide and diverse properties of lithium, in particular, antimicrobial, antiviral, antitumor, anti-stress and antioxidant. The discovery of biological properties and the disclosure of biochemical mechanisms of lithium action became the basis for its use in veterinary and zootechnical practice. Lithium preparations are successfully used to treat various animal diseases, prevent and correct “technological” stresses in poultry, increase its productive qualities and improve the quality of meat products. Despite the biochemical complexity and practical significance of this trace element, lithium is still insufficiently used during feeding poultry due to the lack of optimal standards for introducing it into mixed feed. During developing optimal standards for lithium introduction into mixed feed, it is necessary to evaluate not only the indicators of poultry productivity and product quality, but also the physiological indicators of its development. The effect of additives of different lithium doses in compound feeds on the development of digestive organs in goslings raised for meat was studied in a scientific-economic experiment. The research was conducted on the breed of goslings “Danish Legart”. The duration of experiment was 70 days. The lithium introduction into compound feeds for goslings, in doses of 0.15 mg/kg, 0.20 and 0.25 mg/kg, had a positive effect on the development of their digestive organs, as evidenced by the tendency to increase the intestine mass (by 2.2–4.8 %) and its total length (by 0.5–1.1 %), as well as an increase in the liver mass (by 2.0–7.0 %) and muscle stomach (by 3.4–7.3 %). Goslings had the best macromorphological indicators of digestive development, whose mixed feed were enriched with lithium at the rate of 0.15 mg/kg during the entire growing period. A comparison of goslings live weight of the experimental groups with indicators of the development of intestines, liver and muscular stomach allows to claim that their digestive organs were better developed and functioned more actively during the growing period.

La pertinencia del uso de la contabilidad de gestión ambiental en la toma de decisiones está dirigida a la sostenibilidad de los recursos, sin embargo, las empresas cubanas no consideran en su contabilidad los costos ambientales que generan, ya que aún es limitada la cultura contable asociada al medioambiente y es escasa la base normativa en este sentido. Mayor relevancia ganan las empresas turísticas, que demandan gran consumo de recursos, impactan el medio y a su vez dependen de ellos como atractivos turísticos. La presente investigación tuvo como objetivo general proponer indicadores que permitan medir los costos ambientales derivados de la gestión empresarial del Hotel Roc Presidente. Se aplicaron las técnicas investigativas de análisis documental y de contenido, además de la entrevista, y los datos fueron recolectados de fuentes de información primaria y secundaria. Los resultados obtenidos conllevaron a identificar y describir los aspectos fundamentales de la gestión ambiental del hotel y proponer indicadores afines a dicha gestión que le permitirán a la entidad medir los costos ambientales anuales y tomar decisiones encaminadas a lograr una Gestión Ambiental más eficiente.

Investigation of variable viscosity and thermal conductivity on MHD mass transfer flow problem over a moving non-isothermal vertical plate
Authors: Ahmed Sahin , Hazarika G. C. , Gogoi Geeti 
Published: February 2021

In this paper we investigate numerically the influence of variable viscosity and thermal conductivity on MHD convective flow of heat and mass transfer problem over a moving non-isothermal vertical plate. The viscosity of the fluid and thermal conductivity are presumed to be the inverse linear functions of temperature. With the help of similarity substitution, the flow governing equations and boundary conditions are transformed into non-dimensional ordinary differential equations. The boundary value problem so obtained is then solved using MATLAB bvp4c solver. The effects of various parameters viz. magnetic parameter, viscosity parameter, thermal conductivity parameter, stratification parameter and Schmidt number on velocity, temperature and concentration are obtained numerically and presented trough graphs. Also the coefficient of skin-friction, Nusselt number and Sherwood number are computed and displayed in tabular form. The effects of the viscosity parameter and thermal conductivity parameter in particular are prominent. This study has applications in a number of technological processes such as metal and polymer extrusion.

Published: February 2021

The transom stern offered some advantages over the traditional rounded cruiser stern reducing the resistance of a ship. This can only be achieved if the transom stern is carefully designed with suitable transom immersion ratio. In this study, the influence of different transom area immersion ratios on the resistance components was investigated for a semi-displacement hull and a full displacement hull. The base hull was based on NPL hull form and KCS hull form for a semi-displacement and full-displacement hull respectively. The transom immersion ratios for the NPL hull were varied at a ratio of 0.5, 0.7, 0.8 and 1.0. The resistance of each of the NPL hull form was simulated at Froude number 0.3 up to 0.6. The transom immersion ratios for the KCS hull were varied at a ratio of 0.05, 0.1, 0.15 and 0.3. The resistance of each of the KCS hull form was simulated at Froude number 0.195, 0.23, 0.26 and 0.28. The transoms of both hulls were modified or varied systematically to study the influence of the transom shape or immersion on the total and wave resistance components. The investigation was carried out using a CFD software named SHIPFLOW 6.3 based on RANSE solver. These results on the NPL hull shows that the larger the transom immersion, the higher the resistance will be for a semi-displacement vessel. The increased resistance is contributed by additional frictional and wave resistance components. The results for the KCS hull seems to contradict with the results obtained from the NPL hull. The larger and deeper transom for the case of KCS hull form sometimes can be beneficial at higher Froude number.

The ‘One’s own — Alien’ conflict in Lesia Ukrainka’s dramaturgy: ethnic-national and worldview aspects
Authors: Prylipko Iryna 
Published: February 2021

The paper focuses on the specific features of the ‘One’s own — Alien’ conflict in the dramatic works by Lesia Ukrainka. The majority of her dramas and dramatic poems were written on the basis of foreign cultural phenomena, including the Ancient Greek, Biblical, and other topoi and images. Foreign cultural realities are aimed at the actualization of both the entire context of Ukraine and the writer’s autobiographic discourse in a recipient’s consciousness, forming the imagological paradigms ‘One’s own — Alien,’ ‘Me — Another’. Upon involving the imagological theories, the author of the paper traces the development of dialogue between various cultural realities in Lesia Ukrainka’s dramatic works. This allowed elucidating the peculiarities in the artistic representation of the exotic topoi of different countries as the significant feature of Neoromantic and, in general, Modernist discourses, which were basic for Lesia Ukrainka’s writing. The textual analysis of Lesia Ukrainka’s dramas reveals the specific features of unfolding the ‘One’s own — Alien’ conflict, first of all, on the ethnic-mental level, epitomized in the ‘conquered — conqueror’ collision of the plays “Babylonian Captivity”, “Over the Ruins”, “Orgy” and “Boiarynia”. The other dimension is the worldview and religious level, mostly realized through the collision ‘Antiquity — Christianity’ (“In the Catacombs”, “Rufinus and Priscilla”, “Martian the Lawyer”, and others). It is proved that the ‘One’s own — Alien’ conflict deepens the problems of the works and serves as a way to reveal the essential characteristics of the heroes. The paradigm of the mentioned conflict highlights the borders of the national and personal identities, emphasizes axiological concepts and active ideas, fundamental for Lesia Ukrainka’s dramatic works, such as the tragedy of misunderstanding, the need for constructive dialogue, the necessity of choice, the search for spiritual and national freedom, the meaning of sacrifice, and the role of art.
