Authors: Bezrukov Vladislav , Kuprash Liana , Panteleymonova Tetyana , Kuprash Olena , Gudarenko Svetlana
Published: July 2022

Coronavirus SARS-CoV-2 disease (COVID-19) is characterized by severe and high mortality, which increases significantly with age. This poses a great threat to the elderly. The results of numerous clinical observations suggest that the interaction of drugs used in the COVID-19 treatment and concomitant pathology in elderly patients may worsen the course of the disease and lead to the development of serious complications. Therefore, a need for an individual approach to treatment. Appropriate adjustment of the doses of prescribed drugs and taking into account the interaction of drugs for the treatment of concomitant pathology will help to increase the effectiveness of COVID-19 drug therapy in the elderly.

Tree Susceptibility, Inoculum Availability, and Potential Vectors in a Texas Oak Wilt Center
Authors: Appel D.N. , Peters R. , Lewis R.
Published: July 2022

Three factors important to the spread of Ceratocystis fagacearum, the oak wilt pathogen, were studied in central Texas during 1983-1985. These factors were: 1) the formation of fungal mats on diseased Spanish oaks (Quercus texana), 2) the activities of nitidulid beetles, and 3) the seasonal susceptibility of live oak (Q. fusiformis) to infection by the pathogen. Fungal mats formed on 73% and 3 1% of the trees observed in March of 1984 and 1985, respectively. Peaks of nitidulid activity were observed during February - May of each year. Inoculations were most successful when made in roots or main stems during March or late May. These observations indicate that inoculations by contaminated nitidulids are most likely to occur in spring. Wounding should be avoided then to minimize insect transmission of the fungus.
Indicators of Urban Forest Condition in New Orleans
Authors: Talarchek Gary
Published: July 2022

Urban trees constitute a valuable environmental resource in many cities. Designing a tree maintenance and management strategy depends upon an understanding of the environments of urban trees and stresses on tree health and condition. Using New Orleans, Louisiana as an example, environmental indicators of tree condition are identified using data from sample inventory of trees. Tree condition is related to the types of land covers in the zone of root growth under the tree canopy, the presence of wires in the tree canopy and associated land uses. The inventory also shows that the New Orleans urban forest is a mature forest, which suggests special care is needed in order to protect and replenish the resource, this information can be used to plan urban forestry management strategies in New Orleans.

Authors: Oboko Uche
Published: July 2022

It is not uncommon for people to take offence over what is said and how it is said. These actions often cause conflict and clash of interest in language use in society. Besides, scholars have decried the paucity of research on impoliteness. The paper therefore seeks to fill the gap in knowledge by conducting a research on impoliteness and maxim violations among undergraduates of Madonna University Nigeria, Okija campus.  The study employed the obstructive observation method to observe instances of maxim violations and impoliteness among the students for a period of four months from November 2020 to February2021. Data for the study were collected through recorded language use of the students which were done as not to deter the students in their conversations. The recorded texts were later transcribed and analysed.  Being a qualitative research, data for the study were analysed using a textual method. The analysis was done using Leechian politeness maxims. The paper concludes that studies on politeness and conversational maxim observance should be part of students’ curriculum in order to understand clearly how to avoid conflicts in language use in the university system.

With the development of technology, human beings have successfully predicted and prevented the damage caused by natural disasters. However, due to climate change, society has witnessed the rising actions of forest fire, earthquake, tsunami, etc., and there are many which people cannot prevent, and the level of dangerous situations are increasing rapidly for the Search and Rescue (SAR) operation. Not to mention, more and more people are turning their attention and hobbies to exploring wilderness where they might get lost or, worse, get injured. For that reason, to raise the chance of survival for the victims and reduce the risk for the search team, the use of Unmanned aerial vehicles (UAV) has been proposed. The plan is the headquarters will deploy a fleet of drones to get into the areas where human cannot enter easily and then report the situations as well as the condition of the victims with images and videos. In most research papers, it seems very promising; however, there is still much work that needs to be done. In this paper, some of the features which included for future researches are which algorithm is the most optimal, what standard structure should be used for the drones so it can complete the missions under any kind of circumstances, and how to set up a communication line that guaranty the effective to reduce the level of miscommunication.

How do you know which stock is the right stock to invest in and have no risk of losing their money [1]? Even though there are analysis specialists out there to collect data to calculate which stock is good to be invested in, ultimately people could not afford the cost of specialists and specialists are not able to be there every minute that you want to find them. Therefore, the app Stock Recommendation is created to solve this problem where stock investment suggestions are available in touch anywhere and anytime [2]. This application helps us with what we want to invest in and gather information from recent news to show us about the public opinions towards the stock that we are looking for. Investors will no longer struggle with the problem that is the stock that they want to invest in, a good stock or a bad stock, so no money will be lost from the investor's pocket and rather, they will gain my money [4].

Published: July 2022

Process monitoring is an important element for the long-term reliable functioning of any automated system. In fact, monitoring system is constituted of sensors installed in the physical system, in order to analyse, observe and control production systems in real time. In network, these sensors may interact with one other and with an external system via wireless communication. With recent advances in electronics, tiny sensors have appeared. Their low cost and energy consumption allow them to perform three main functions: capture data, provide information and communicate it via sensor network. In this paper, we had interested to the Cyber-Physical System (CPS) and Prognostics Health Management (PHM) domain; The CPS is one of the most important advanced technologies, it connects the physical world with the cyber using a communication layout. In other side, PHM has become a key technology for detectingfuture failures by predicting the future behaviour of the system.
A Pedestrian Counting Scheme for Video Images
Authors: Cheng Chi-Cheng , Wu Yi-Fan
Published: July 2022

Pedestrian counting aims to compute the numbers of pedestrians entering and leaving an area of interest based on object detection and tracking techniques. This paper proposes a simple and effective approach of pedestrian counting that can effectively solve the problem of pedestrian occlusion.Firstly, the moving objects are detected by the median filtering and foreground extraction with the improved mixed Gaussian model. And then the HOG (Histogram of oriented gradient) features detection and the SVM (Support vector machine) classification are applied to identify the pedestrians. A pedestrian dataset containing 1500 positive samples, 12000 negative samples, and 420 hard examples, which gave the false discriminant results with the initial classifier, also considered as negative samples to enhance classification capability is employed. In addition, the Kalman filtering with BLOB analysis for dynamic target tracking is chosen to predict pedestrian trajectory.This method greatly reduces the target misjudgment caused by overlapping and completes the two-way counting. Experiments on pedestrian tracking and counting in video images demonstrate promising performance with satisfactory recognition rate and processing time.

Published: July 2022

The scientific community is looking for efficient solutions to improve the quality of life in large cities because of traffic congestion, driving experience, air pollution, and energy consumption. This surge exceeds the capacity of existing transit infrastructure and parking facilities. Intelligent Parking Systems (SPS) that can accommodate short-term parking demand are a must-have for smart city development. SPS are designed to count the number of parked automobiles and identify available parking spaces. In this paper, we present a novel SPS based on real-time computer vision techniques. The proposed system provides features including: vacant parking space recognition, inappropriate parking detection, forecast of available parking spaces, and directed indicators toward various sorts of parking spaces (vacant, occupied, reserved and handicapped). Our system leverages existing video surveillance systems to capture, process image sequences, train computer models to understand and interpret the visual world, and provide guidance and information to the drivers.

Published: July 2022

Quality of silage corn is assessed over dry matter ratio, dry matter intake, crude protein, energy, and mineral contents. In this study, the effects of different weed densities on the silage quality of corn were investigated in the 2019 and 2020 years. Silage pH, Fleig score, dry matter ratio, crude protein, NDF, and ADF contents were assumed as silage quality parameters. The experiment was established in randomized block design. Silage pH, Fleig score, dry matter ratio did not present significant variations between the years but crude protein, NDF, and ADF contents significantly varied. Weed density significantly affected NDF content only. Although weed density did not have a significant effect on the silage quality of corn, cultivation should be carried out weed-free for high yielding.

In this study, we examine the association between firms’ innovation process and their product quality improvement and new product introduction strategies. Our focus is on the distinction between firms’ product quality improvement and variety extension objectives. We use data from Turkish Statistical Institute (TURKSTAT) Innovation Survey between the years 2014 and 2016. According to the descriptive results, number of firms report that product quality as very important is greater than the firms report that product variety. Logit estimations results show that majority of the product variety objective and technology level indicators are significant and positively related with probability of product innovation. There is also a positive relationship between probability of product innovation and patent applications for small and medium sized firms. Moreover, probability of innovation is positively related with variety objective whereas quality objective indicators are insignificant.

Published: July 2022

Abstract. The role of clouds in the surface radiation budget is particularly complex in the rapidly changing Arctic. However, despite their importance, long-term observations of Arctic clouds are relatively sparse. Here, we present observations of cold clouds based on 7 years (2011–2017) of ground-based lidar observations at the Arctic Lidar Observatory for Middle Atmosphere Research (ALOMAR) in Andenes in the Norwegian Arctic. In two case studies, we assess (1) the agreement between a co-located cirrus cloud observations from the ground-based lidar and the spaceborne lidar aboard the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite and (2) the ground-based lidar's capability to determine the cloud phase in mixed-phase clouds from depolarization measurements. We then compute multiyear statistics of cold clouds from both platforms with respect to their occurrence, cloud top and base height, cloud top temperature, and thermodynamic phase for the 2011–2017 period. We find that satellite- and ground-based observations agree well with respect to the coincident cirrus measurement and that the vertical phase distribution within a liquid-topped mixed-phase cloud could be identified from depolarization measurements. On average, 8 % of all satellite profiles were identified as single-layer cold clouds with no apparent seasonal differences. The average cloud top and base heights, combining the ground-based and satellite measurements, are 9.1 and 6.9 km, respectively, resulting in an average thickness of 2.2 km. Seasonal differences between the average top and base heights are on the order of 1–2 km and are largest when comparing fall (highest) and spring (lowest). However, seasonal variations are small compared with the observed day-to-day variability. Cloud top temperatures agree well between both platforms, with warmer cloud top temperatures in summer. The presented study demonstrates the capabilities of long-term cloud observations in the Norwegian Arctic from the ground-based lidar at Andenes.
Origins and suppression of bifurcation phenomena in lower-order monsoon models
Authors: Kumar S. Krishna , Seshadri Ashwin K.
Published: July 2022

Abstract. South Asian monsoon rainfall varies rapidly in the paleoclimate record, and this has been interpreted using simple models as arising from tipping points. This study explores a class of simple monsoon models, based on convective quasi-equilibrium, and the bifurcations permitted by their mathematical forms. Specifically, low-order models are derived starting from the Quasi-equilibrium tropical circulation model (QTCM) to examine the bifurcations present. Previous studies that have pointed to an abrupt transition in low-order monsoon models typically identify a saddle node bifurcation occurring as a result of changes in the radiation budget. The present study shows how such saddle node structures arise across a wide range of modeling assumptions and parameter values, and yet permit a continuous transition into and out of precipitating regimes without any bifurcation being physically manifest. This is because the bifurcation points lie in a regime that is not physically relevant when the dry thermal stratification is sufficiently large. As a result, these low-order models can be interpreted as possessing abrupt transitions that are latent in the equations but do not express themselves physically. However, when the dry thermal stratification is reduced, bifurcations can occur. This paper also shows that these latent saddle-node structures are themselves part of the unfolding of a pitchfork bifurcation. These findings help understand the role of stabilizing phenomena on the general absence of abrupt monsoon transitions despite the presence of nonlinear terms in these models.

Abstract. Forests are rockfall-protective ecological infrastructures as a significant amount of kinetic energy is absorbed during consecutive rock–tree impacts. Although many recent works have considered rock impacts with standing trees, the effect of lying deadwood in forests has not yet been considered thoroughly, either experimentally or numerically. Here, we present a complete examination of induced rockfall experiments with sensor-equipped, 45 kg, artificial rocks on a forested area in three different management stages. The trilogy is conducted in a spruce forest stand (i) in its original state of forest; (ii) after a logging operation with fresh, lying deadwood; and (iii) after the removal of the deadwood. The tests allow us to directly quantify the effect of fresh deadwood on overall rockfall risk for the same forest (slope, species) under three different conditions. The study yields quantitative results on the barrier efficiency of the deadwood logs as only 3.6 % of the rocks surpass the deadwood section. The mean run-out distance is reduced by 42 %. Conversely, the run-out distance increases by 17 % when the cleared stand is compared to the original forest. These results quantitatively confirm the benefits of nature-based mitigation measures integrated into forestry practice, whose detailed effect has to be scrutinized for higher rockfall energies. Based on the experimental results, we extended a modern rockfall code by three-dimensional deadwood logs to incorporate such complex but realistic forest boundary conditions.

Published: July 2022

The paper considers the features of applying the project method as the latest pedagogical technology in the process of developing English grammar skills in students of philological specialities. The relevance of the study is conditioned by the need to find an effective methodology for implementing video projects (a type of project method) in teachers’ universities. The purpose of the study is to find out the effectiveness of using video project technology to improve the grammatical competence of philology students. In the course of the study, the method of critical analysis of literature was applied to investigate the goals, methods, and means of project technology and to formulate the conclusions; the method of scientific observation of the educational process contributed to the direct observation of students’ activities; the method of studying and generalising the experience of teachers revealed methodological techniques and methods in the development of proper grammar skills of students; the questionnaire method helped to establish the level of knowledge of students about the ways of learning and teaching a foreign language; the experimental method was used to prove the research hypothesis; the method of systematisation and generalisation was used in the analysis of findings. It is found that the essence of the concept of grammatical competence of a philology student consists in a set of knowledge about the grammatical organisation of the language system, and in the ability to operate with this knowledge in a certain speech activity. It is proved that by improving grammar, students develop their speech competencies — in reading, writing, listening, and speaking. The expediency of using information and communication technologies in studying English grammar, especially in distance learning, is substantiated. The use of the project method is proposed to improve the grammatical and informational skills of future foreign language teachers. It is confirmed that this method stimulates the development of cognitive and creative skills of students, is based on the systematic organisation of searches of a problem-based educational nature, encourages the independent acquisition of Information, its comprehension, and application in practice. In addition, project technology helps students acquire teamwork skills, careful planning, and increased motivation to improve their own communication competence
