Experiments for the Definition of Communication Models: The Visual Identity of Navigation Companies in Relation to On-Board Services
Authors: Falcidieno Maria Linda , Ruggiero Maria Elisabetta , Malagugini Massimo , Torti Ruggero , Sorrentino Nicoletta
Published: August 2022

The The advent of the pandemic in the last two years has called into question the communication apparatus referred to the identities of the shipping companies: not only this must respond to the needs of marketing and identification of those who are to be considered real brands, but even today it must respond to the need for ‘reassurance’ regarding a new aspect, perhaps less considered before, namely that of ‘health and hygiene’ safety. Forms of innovation introduced in recent years, such as those entrusted to touch screens, have proved difficult to pursue and therefore printed communications ad personam, app and social media, are perhaps more effective, highlighting a progression of targets that are gradually younger. Many media have been involved in this process and consequently the adopted languages have changed according to different needs. The research work here presented intends to illustrate a study-methodology starting from the assumptions of visual and linguistic analysis of the state of the art in order to arrive at defining reflections and proposals. The experimentation was also conducted with the involvement of didactic experiences (seminars and applications) from which it was possible to deduce some useful reflections for further ideas, such as the perception of certain problems, the need to resort to integrated communication systems and finally the possibility development of specific applications. In this context, it is worth noting the role that social media play today in the dissemination of visual communications which, as a whole, amplify the perception of a brand’s identity and allow for in-depth information on issues, subject to sudden changes, just like the one mentioned as a premise.

In this study, the use of natural fibres (flax and basalt) in combination with a recyclable epoxy matrix based on cleavable amines is suggested for improving the sustainability of marine industry. In addition, a new and eco-friendly anodizing process based on tartaric sulfuric acid solution (TSA) and a pore widening step in a NaOH aqueous solution was carried out on aluminium alloy (AA5083) to evaluate its effect on the adhesion strength and damage tolerance after low velocity impact of co-cured adhesive joints with a basalt fibre reinforced and recyclable laminate. The durability in marine environment was simulated by exposing samples to salt-fog spray conditions over a period of 90 days. Results highlighted the potential of the proposed natural fibre composites, even though the interfacial adhesion with the recyclable matrix needs to be improved, while the anodizing treatment significantly increased the damage tolerance of the joints irrespective of ageing, impact energy and temperature compared to the reference joints.
“One digit” Estimation of Navigation Area Parameters for a Monohull Fast Ferry
Authors: Kanifolskyi Oleksandr , Ruggiero Valerio
Published: August 2022

In modern versions of the Directive 2009/45/EC of the European Parliament and of the Council on safety rules and standards for passenger ships and in some rules of classification societies, for example Registro Italiano Navale, options for the designation of the navigation area for passenger ships are proposed. Fast ferries carry not only Ro-Ro cargo, but also a large number of passengers and therefore belong to the type of passenger ships. Considering the high speed of these vessels, up to 40 knots and the short distance from the port of refuge during the voyage, liferafts are the main life-saving appliances on board the high-speed ferry but the main parameter regarding the safety is the possibility for the passengers to be rescued by a “rescue vessel” or the distance from a safe port. By the rules of the International Code of Safety for High-Speed Craft, the time for rescuing people from aboard a high-speed passenger ship is limited. In this article, the characteristics of the rescue vessel for rescuing passengers from the ferry will be determined. The worst case for a rescue craft at moving against a wave, with a typical wave height for this area, will be considered. The permissible value of the width of the navigation zone will be determined, taking into account the survival time of a person at the water temperature of a given area. When designing a high-speed passenger ferry, it is very important to know at an early stage of the project about a possible decrease in speed when moving on a sea wave. This speed reduction can be predicted at an early stage of the project based on the data on the wave parameters in the region and the characteristics of the fast ferry. In this way the safety of the primary vessel will be enhanced by the fact that the estimated time for rescue or to reach a safe port will be evaluated in a realist way and not only with a theoretical parameter. To solve these problems at the first stages of the project, for a “One digit” assessment, Energy Wave Criterion (EWC) will be used that takes into account the kinetic energy of the vessel and the energy of the wave.

A Methodology for the Hull Forms Design of a Passenger Catamaran for the Venice Lagoon
Authors: Braidotti Luca , Bertagna Serena , Zanin Mattia , Padolecchia Donato , Marinò Alberto , Bucci Vittorio
Published: August 2022

The proper definition of the main geometric coefficients and the hull forms of a passenger catamaran must be carried out from the early design stage, due to its strong impact on the resistance, propulsion and the generated wave pattern. This is a primary concern especially in fragile environments, such as the Venice Lagoon, where waves increase erosion phenomena. In this work, a two-phase methodology for the definition of the hull forms of a passenger catamaran, based on both a parametric and CFD analysis, is presented. In the first phase, systematic series data are used to parametrically evaluate possible combinations of main hull dimensions (breadth of the demi hull, deadrise angle), selecting the best one to fit a specific operative scenario (minimisation of required energy). Then, after the validation of mesh parameters with a benchmark hull, the best hull forms are assessed through CFD simulations. To study the interference between the two hulls and select the proper configuration two different distances of the demi hulls are investigated. The methodology has been applied to the preliminary design of a 10 m passenger catamaran for the Venice Lagoon. Routes from the city centre to Marco Polo Airport or Torcello Island have been considered.

Published: August 2022

The paper aims to show the design procedure for a Class-2 dynamic positioning system, from initial conceptualisation upon factory assessment test. The approach involves the use of simulation–based design combined with hardware–in–the–loop testing. This kind of approach involves a detailed knowledge of the investigated ship but gives significant well-known advantages. A custom simulation platform has been developed to have realistic feedbacks of the case-study ship. The dynamic positioning controller structure, including regulator, force and thrust allocation; have been conceptualised, and then, after the porting procedure, the dynamic positioning software has been downloaded in the real programmable logic controller. Several hardware–in–the–loop tests have been carried out to fine-tune the controller parameters. The results show, under different environmental conditions, the respect of the design criteria.

Authors: Bono Gianpaolo Damiano , Buttaro Gianni
Published: August 2022

Nowadays, underwater vehicles have a wide range of applications both in military, scientific, commercial and security fields. Next to Submarines, Autonomous Underwater Vehicles (AUVs) are increasingly spreading thanks to their capabilities to carry out a significant variety of missions, including interacting with underwater infrastructures, coastal and underwater inspections, intelligence gathering, environmental and fish monitoring and, of course, research and fight against underwater threats. One of the main performance characteristics of an underwater vehicle is its resistance curve. The estimation of this curve is a crucial factor in preliminary design phases in order to correctly choose and dimension the right propulsion plant and propeller and, in general, to reach operational requirements. In the last decade, with the advent of higher computing power and robust algorithms, the application of Computational Fluid Dynamics (CFD) analysis is rapidly emerging as a fast, reliable and cost-effective tool in the assessment of the hydrodynamic performances. The paper offers the implementation of a “virtual wind tunnel” based simulation and the influence of the hull and sail shape of an underwater vehicle. A simulation was conducted and the numerical results were validated by comparing them with the available experimental data obtained from the literature. In the second part of the paper, several modern technologies related to the underwater sector were analyzed to identify their influence on the shape during the design phase of an underwater vehicle. Particular considerations were dedicated to the different positions and profiles of the sail allowed by the integration of the optronic periscopes. Further considerations were made on the shape of the bow necessary for the integration of sonars of different types and sizes. In conclusion, various tests were carried out in the simulation environment in order to detect the optimized solutions for each case studies.
Genetic and agrotechnological features of the formation of sowing qualities of oat varieties when applying increasing doses of mineral fertilizers in the forest-steppe of the Trans-Urals

Published: August 2022

Abstract. The purpose is to study the genetic and agrotechnological features of the formation of the sowing qualities of oat grain at various agricultural backgrounds in the forest-steppe of the Trans-Urals. Materials and methods. The research was carried out on an experimental field located in the forest-steppe zone of the Trans-Urals. The object of the study were three varieties of oats, which were sown on different agricultural grounds, ensuring the formation of yields from 3.0 to 6.0 t/ha of grain. The mass of 1000 grains, the proportion of fine grains, germination energy and laboratory germination were determined. Results. On the natural agricultural background, the Talisman and Otrada varieties form a yield of 1.41 and 1.85 t/ha with a fraction of fine grain (< 2.0 mm) up to 11 %. In the Foma variety on the natural agricultural background, this indicator was 7.5 %. The introduction of mineral fertilizers for the planned yield from 3.0 to 5.0 t/ha reduces the amount of fine grain only in the Talisman and Foma varieties. Grain with high sowing qualities is formed on a natural agricultural background and when fertilizers are applied to the planned yield of 3.0 t/ha. The grain obtained on such variants had 72–76 % germination energy and 91-93% laboratory germination. Grain obtained at a high and very high agricultural background had low sowing indicators: germination energy and laboratory germination reached minimum values: 57–59 and 61–63 %, respectively. It was found that the mass of 1000 grains depends on fertilizers by 23.4 % and 30.0 % on the weather conditions of the growing season. Varietal characteristics account for 9.6 %. Laboratory germination of the studied varieties by 86.8 % depends on the level of mineral nutrition. Scientific novelty. For the first time for the Northern Trans-Urals, an optimal level of agricultural background has been established, providing maximum yield of oat grain with high sowing qualities. Recommendations. In the forest-steppe zone of the Trans-Urals, the cultivation of oats for seed purposes is recommended in fields with an average or increased agricultural background, designed to obtain yields of 3.0 and 4.0 t/ha.
Production and economic features of agricultural zoning: regional aspect
Authors: Korabel'nikov Ivan
Published: August 2022

Abstract. Purpose. The article is devoted to the study of spatial differentiation of the basic conditions for the development of agricultural production and the identification of production and economic features of agricultural zoning of the Volgograd region, the parameters of which determine the development of priority areas and tools for the territorial development of the agrarian economy of the region. Methods. The methodological basis of this article is formed by the general scientific principles of the territorial (spatial) approach; methods of analysis – computational and constructive, system analysis, expert assessments, economic and statistical; the basic research tool is agricultural zoning, the practical use of which makes it possible to identify peculiar territorial formations with their characteristic production and economic features. Scientific novelty. The presented generalization of the spatial differentiation of the basic conditions for the development of agricultural production in the region made it possible to identify the production and economic features of agricultural zoning, manifested in: pronounced natural zonality of the distribution of agricultural productive forces; changes in the nature and production and economic proportions of agricultural production when moving from north to south and from west to east; local manifestations of contrasts “center – periphery” in the countryside. Results. Within the framework of the substantiation of the production and economic specifics of the zoning of rural territories of the Volgograd region, the parameters of specialization, settlement of the population and its self-sufficiency with agricultural food, as well as the efficiency of the functioning of agricultural production were investigated. Processing of a set of socio-economic indicators made it possible to argue the priorities of territorial development of agricultural production in agricultural areas, the essence of which is: the need for regulatory influence from the state to stimulate the processes of diversification of activities and compliance with scientifically sound crop rotations on the most fertile lands of the region; comprehensive investment (concessional lending and targeted project financing, subsidies and subsidies) and infrastructure (development of land reclamation, cooperation, logistics and processing) support for livestock and feed production in the arid areas of the region.
Digital technologies in pig breeding in Russia
Authors: Smirnova Viktoriya
Published: August 2022

Abstract. The article analyzes the process of promoting digital technologies in pig breeding. Digital transformation is understood as the introduction of modern information technologies at all stages of production, including the fundamental restructuring of the enterprise management system. In the real sector, the introduction of innovative technologies is largely determined by external factors. Federal programs require the promotion of information technologies in all spheres of activity in order to increase labor productivity and achieve the competitiveness of Russian products in international markets. However, the introduction of these technologies is closely related to the organizational form of enterprises. Digital technologies are not always available and economically profitable for medium and small farms. The purpose of the study is to reveal the features of the introduction of digital technologies into the work of pig industry enterprises. Methods. In the course of the research, general scientific methodological approaches and methods of economic analysis were applied. The scientific novelty of the study lies in the substantiation of priority directions for the introduction of innovative technologies in pig breeding. Results. Trends and problems of introduction of digital technologies in pig breeding are revealed. The advantage of pig breeding, in comparison with other branches of agriculture, is a high technological level. In 2015–2020, large Russian enterprises reached European production standards. Dependence on the import of breeding pigs is decreasing. In the context of the deglobalization of the economy, new threats to the promotion of innovation are emerging: on the part of suppliers – a decrease in the supply of ready-made technologies, on the part of manufacturers – a decrease in the profitability of the industry and investment in production. The necessity of state support for digitalization of pig breeding in medium and small farms is substantiated.

Verbal component of linguo-country-studying competence building with the help of idioms
Authors:   Kamyanets-Podilsky Ivan Ohienko National University, Nykytiuk Svitlana
Published: August 2022

The article deals with the background knowledge verbal component, namely its frequency occurrence in the idioms which described a character of the nation. Socio-cultural competence consists of country-studying and linguo-country-studying competences. Country-studying competence is students' knowledge of the culture of the country whose language is being studied (knowledge of history, geography, economy, and government, features of life, traditions and customs of the country). Linguo-country-studying competence supposes students' mastery of speech and nonspeech (facial expressions, gestures accompanying utterances) behavior of native speakers in certain communicative situations that is, the formation of students' holistic system of ideas about the national and cultural characteristics of the country. Usually participants of the communicative act try to determine the total amount of knowledge for them from the beginning and then intuitively take it into account, which is further reflected in the form and content of speech. Such general knowledge for all participants of communication is called background knowledge, in the structure of which there is a verbal component. Idioms of any language are the most valuable linguistic phenomenon which reflects the national culture, customs and beliefs, creativity and people history, which language is being learnt. Idioms are characterized by figurative motivation which is directly related to the worldview of the native people therefore, it can be argued that idioms are culturally and nationally labeled. They may be claimed to serve an appropriate source for forming the verbal component of the pupils’ country-studying competence. The exercises for the verbal component of country-studying competence building were presented. They are original texts or texts composed on purpose with idioms; pre- and post text exercises for speech skills building with the defined idioms. The tasks with the defined topic were proposed: pre-reading tasks; read the following text; post-reading tasks; agree or disagree; fill in the gap with an appropriate idiom; choose the sentence that best fits the following; make up a story to illustrate each sentence bellow.

This study explores the importance of service quality in determining perceived value, satisfaction, and loyalty, specifically for nonprofit sport clubs in Germany, collecting data from 24 sport clubs ( N = 427). The findings of the study indicated that (1) service quality has a major impact on perceived value, satisfaction, and loyalty, which demonstrates the significance of service quality as a determinant of perceived value, satisfaction, and loyalty; (2) perceived value is found to be a significant factor affecting satisfaction and loyalty as well as a mediator between service quality and satisfaction; and (3) satisfaction has a positive influence on loyalty and mediates the relationship between service quality and loyalty. The empirical results highlight the importance of understanding how the elements of service quality play a crucial role in the retention of sport club members.
The Impact of Sponsorship on Social Media Engagement: A Longitudinal Examination of Professional Sport Teams
Authors: Naraine Michael L. , Bakhsh Jordan T. , Wanless Liz
Published: August 2022

Abstract: Social media has become an important frontier in the sport sponsorship paradigm (Dees, 2011), offering brands a powerful mechanism to stimulate consumer engagement (Vale & Fernandes, 2018). Despite this potential, the extent to which social media content, as part of a sport sponsorship’s leveraging activities, can yield consumer engagement behaviors is unknown. Thus, the purpose of this study was to examine the impact of integrating sponsors into the social media posts of sport organizations on fan engagement. A total of 13,542 Instagram posts from four professional sports teams were extracted from 2017–2019. A regression analysis revealed that sponsored content negatively affected engagement levels. Consequently, brands need to be more cognizant that simply sponsoring content in an inauthentic, forceable manner may not yield the results they are seeking through their association. Furthermore, sport organizations need to reconsider their social media strategy, working with partners to organically embed sponsors into content.

Published: August 2022

Urban Air Mobility (UAM) is a new concept offered for solving urban transportation system problems, contributing to reducing traffic congestion, atmospheric pollution and mobility around metropolitan areas which is progressively an evolved aviation market. Facing the evolved dynamics in the airspace and on the ground, developed new technologies are able to withstand against destroy transportation infrastructures of the big cities, making it necessary to develop UAM services in the megapolises and regional transportation sector. Based on new technologies and modern business approaches, applying the next generation aviation infrastructure makes it capable of setting up a novel air traffic within the urban environment. This case study aims to explore the urban air transport advantages, particularly adoption of UAM, which might be an alternative next generation air transportation system. Referring to the collected operational data and design performances of the UAM, in this paper, we will try to describe a multi approach studying differences between traditional aviation transportation and UAM operation. The first step of the study consists of defining an airspace classification for UAM mission and use of applicable requirements for air navigation service providers and second part of the study describes performing UAM infrastructure and design of vertiports necessary for vertical take-off and landing (VTOL) vehicles. Detailed design specification is not included in this study but limited characteristics are indicated according to the VTOL manufacturer that are obtained from the test results. As far as VTOL vehicles have not started their mission yet, the UAM operators are at the stage of development to set up their future operation. The expected trend provides justifiable assumptions of the necessity of establishing the new transportation ramification within the aviation industry, upon transforming existing business activities and regulations.

This study aims to determine the quality of forage ferns (Gleichenia linearis) as animal feed for ruminants in West Kotawaringin Regency, Central Kalimantan. Ferns fermented with molasses and starbio to determine nutrient content, in vitro dry matter digestibility (IVDMD) and in vitro organic matter digestibility (IVOMD). This research method uses a completely randomized design (CRD) with four treatments and three replications. The feed treatments were P0 (control): 100% fermented paku resam, P1= P0 + 2% molasses + 2% starbio, P2= P0 + 2% molasses + 4% starbio, and P3 = P0 + 2% molasses + 6% starbio. The parameters of this study were physical quality, feed nutrients, IVDMD and IVOMD. The results showed that the physical quality of all treatments was brown, smelled, and had a hard texture. Nutrients of ferns contain P0= (CP 10.79%, TDN 60.8%), P1= (CP 10.41%, TDN 65.78%), P2= (CP 13%, TDN 68.54%), and P4= (CP 10.90%, TDN 61.14%). The results of IVDMD showed a change (P<0.05) in each fermentation treatment, the highest in P2 of 21.13% or an increase of 40.68% compared to control (15.02%), then in P3 of 18.25% or an increase of 21.5% , and in P1 by 18.2% or an increase of 21.17%. The results of IVOMD showed a change (P<0.05), the highest in P2 of 17.2% or an increase of 12.79% compared to control (15.25%), in P1 of 15.49% or an increase of 1.57%, will but in P3 it was 14.62% decreased by 4.13%. The conclusion of this research is the addition of molasses and starbio to fermented feed increases the digestibility of dry matter and organic matter to the level of molasses 2% + starbio 4%. However, as a ruminant feed ingredient, ferns have a low digestibility.

Ovary is one of the essential reproductive organs in human being. A detailed histomorphological feature of ovary is an un-debatable for diagnostic and therapeutic purpose for ovarian disease. The standardization of the morphological and histological measurements of ovary in general in Bangladeshi people is essential to increase the knowledge regarding anatomical variation in our population. So a research work on detailed anatomical parameters of ovary is an un-debatable.

Objective: To find out the follicles in different age groups post mortem human ovary.

Methodology: The cross-sectional observational study was carried out in the Department of Anatomy, Sylhet MAG Osmani Medical College, Sylhet in collaboration with the Department of Forensic Medicine, Sylhet MAG Osmani Medical College during the period from January 2016 to December 2016. Sixty pairs of human postmortem ovaries were collected. The inclusion criteria were dead bodies autopsied within 36 hours of death. Considerable signs of decomposition or decomposed dead body, presence of gross ovarian disease and any history of poisoning cases were excluded. All the specimens were examined for morphological parameters but only 18 specimens were examined histological parameters.

Results: The highest total numbers of the follicles were found in the age group A and lowest total numbers of the follicles were in the age group C. The differences of total numbers of the follicles were significant between group-A and group-B (p<0.001); and group-A and group-C (p<0.001); but no significant difference was observed between group-B and group-C (p=0.080).

Conclusion: Histomorphologically, the total number of the follicles is found maximum at reproductive years and is declined through perimenopause and postmenopause.

Cardiac troponin I is a highly sensitive and specific marker of myocardial necrosis. In addition to the strong diagnostic role of cardiac troponin I its prognostic value has become increasingly well established for patients presenting with acute coronary syndrome. However, there have been conflicting reports on the value of troponin in the setting of PCI is stable and unstable coronary disease.

Objective: To assess the role of cardiac troponin I in predicting outcome after PCI.

Methods and results: CTnl was measured immediately before and at 8 hrs and at chest pain after PCI in 80 consecutive patients with stable coronary artery disease. Twenty of them with post procedural CTnl level 50.4 ng/ml were excluded because of the inability to do repeat estimation of CTnl at chest pain. Among the rest sixty patients, thirty had post procedural troponin <0.4 ng/ml were considered as group I and thirty had post procedural rise of CTnI >0.4 ng/ml were considered as group II. CTnl level, 0.4 ng/ml was consider as cut off value for grouping patients was based on ACC/ AHA/ ISCAI 2005 guide line definition of peri procedural myocardial infarction. The study end point was the following adverse cardiac events-recurrent angina, cardiogenic shock, significant arrythmias, congestive heart failure, Q wave MI, repeat PCI/ CABG, death during hospital stay and at 30 days follow up. In this study base line parameters like age, sex, BMI, risk factors, anginal class, base line ECG and LVEF showed no statistically significant difference between the two groups. Angiographic parameters such as types of lesion and procedural complications shows statistically significant difference between two groups. In-hospital adverse cardiac events after the procedure was significantly higher in group II than group 1 (P<0.01). The mean duration of post procedural hospital stay was also significantly higher in group II than group 1 (P<0.01). At 30 days follow up there has no incremental risk of adverse cardiac events.

Conclusion: CTnl rise at peri procedural myocardial infarction level was observed in 37.5% of this study patient. This level of CTnl was significantly predictive of an increased risk of adverse cardiac events at hospital follow up.
