A Mechanical Modelling and Simulation Method for Resolving PIM Problems in Antennas
Authors: Chen Chen , Gu Yangyang
Published: January 2022

Passive intermodulation (PIM) generated from antennas is a nonlinear distortion phenomenon and causes serious problems to communication quality. Traditional radio frequency (RF) solutions focus on testing the final product to find the PIM source. However, it cannot solve the stability of PIM after the antenna is vibrated. This paper introduces a new method to improve the stability of PIM in the design phase. By studying the mechanism of PIM generation, a simulation method is proposed in this paper by applying mechanical finite element simulation and simulating the structural design of the device under test. Then, the stress at the PIM source is reduced, thereby the PIM stability of the product is improved. This paper adopts this method by studying a typical product, finding the root cause that affects the product PIM magnitude and stability, and optimizing its design. The PIM value of the new scheme is stable by making a prototype and testing. The method provided in this article can effectively improve product development efficiency and assist designers in avoiding the risks of PIM before the product’s manufacturing.
Interactive Deep Learning for Shelf Life Prediction of Muskmelons Based on an Active Learning Approach
Authors: Albert-Weiss Dominique , Osman Ahmad
Published: January 2022

A pivotal topic in agriculture and food monitoring is the assessment of the quality and ripeness of agricultural products by using non-destructive testing techniques. Acoustic testing offers a rapid in situ analysis of the state of the agricultural good, obtaining global information of its interior. While deep learning (DL) methods have outperformed state-of-the-art benchmarks in various applications, the reason for lacking adaptation of DL algorithms such as convolutional neural networks (CNNs) can be traced back to its high data inefficiency and the absence of annotated data. Active learning is a framework that has been heavily used in machine learning when the labelled instances are scarce or cumbersome to obtain. This is specifically of interest when the DL algorithm is highly uncertain about the label of an instance. By allowing the human-in-the-loop for guidance, a continuous improvement of the DL algorithm based on a sample efficient manner can be obtained. This paper seeks to study the applicability of active learning when grading ‘Galia’ muskmelons based on its shelf life. We propose k-Determinantal Point Processes (k-DPP), which is a purely diversity-based method that allows to take influence on the exploration within the feature space based on the chosen subset k. While getting coequal results to uncertainty-based approaches when k is large, we simultaneously obtain a better exploration of the data distribution. While the implementation based on eigendecomposition takes up a runtime of O(n3), this can further be reduced to O(n·poly(k)) based on rejection sampling. We suggest the use of diversity-based acquisition when only a few labelled samples are available, allowing for better exploration while counteracting the disadvantage of missing the training objective in uncertainty-based methods following a greedy fashion.
Determinants of Recreational Activities Choice in Protected Areas
Authors: Franceschinis Cristiano , Swait Joffre , Vij Akshay , Thiene Mara
Published: January 2022

Conciliating nature conservation and tourism development is an increasingly important task for authorities in charge of managing protected areas and requires an adequate knowledge of visitors′ preferences and recreational behavior. In this light, we used data collected by means of a choice experiment to investigate recreational preferences at Dolomiti Bellunesi National Park, a protected area located in Northeastern Italy. More specifically, we analyzed the determinants of visitors’ decisions to engage with different activities in the park. This is important information for park managers, as different recreational activities have both different impact on the natural heritage and different capability to generate revenue for nature conservation and for enhancing the quality of life of local communities. The findings of our study suggest that the choice of recreational activities is mainly driven by the features of recreational sites and by visitors’ personal characteristics. Concerning park features, visitors’ choices seem to be mostly driven by features directly related to each activity, such as thematic trails for hiking and climbing routes for rock climbing. Among visitors′ characteristics, we found that both previous experience with the activity and socio-demographic characteristics had a significant effect on activity choice. Overall, the results of our study can help park authorities in developing management plans aimed specifically at attracting a larger number of visitors of a certain type, which is an important tool to foster the more sustainable forms of tourism.

Published: January 2022

In underground engineering such as tunnel engineering, the condition of surrounding rock such as water-containing jointed rock mass is a common engineering geology. For broken, water-containing surrounding rock, the reasonable measures to prevent and drain water has always been a key issue. Based on the statistical information of the structural surface of the surrounding rock of the Hongtuzhang tunnel, DIPS software was used to classify the structural plane of the tunnel. Based on the statistical analysis of the occurrence, size, and density of the structural plane, the two-dimensional structural plane network model of the rock mass was established, and the permeability tensor (K1 = 1.61 × 10−6 m/s, K2 = 5.78 × 10−7 m/s) was calculated. Consider the worst orientation, the permeability tensor (K1 = 1.61 × 10−6 m/s) was selected to calculate the grouting design. Based on the theory of limited discharge, the influence of parameters of permeability coefficient ratio n and thickness of grouting layer Tg on the tunnel water inflow and lining external water pressure was analyzed. The recommended value of tunnel drainage was 3.0 m3/m∙d, then the corresponding grouting circle parameters were put forward (permeability coefficient ratio n = 100, thickness of grouting layer Tg = 8 m).

Dinitrohydrazines and Interaction of Them with Some Group-II Metals - DFT Treatment
Authors: Türker Lemi
Published: January 2022

Dinitrohydrazines and interaction of them with some group-II metals have been considered within the restrictions of density functional theory and the basis set applied (B3LYP/6-311++G(d,p)). Dinitrohydrazine has two isomers as geminal and vicinal. The calculations reveal that both of them are structurally stable. The vicinal form electronically is more stable and thermo chemically more favorable than the other isomer. The beryllium magnesium and calcium (1:1) composites of them are considered. The results indicate that only the beryllium composites (geminal and vicinal) are structurally intact while the others undergo decomposition due to reductive cleavage by the metals. The decompositions occurred exhibit variations from one composite to the other.

Dynamics of biochemical indicators in the process of mucous-bone wound healing in cases of spontaneous periodontitis on the background of different organism reactivity
Authors: Yarov Yu.Yu.
Published: January 2022

The dynamics of biochemical parameters (lipid peroxidation, medium molecular peptides, prostaglandins) blood levels after periodontal tissues surgery of 24 dogs with spontaneous periodontitis has been studied. Animals were divided into groups with normal, hyper- and hyporeactivity of the body. It has been revealed that the changes of the studied biochemical parameters during normoreactivity of the organism are mutually correlated, which provides synchronization of necrotic and reparative processes in the healing of mucosal wounds after patch surgery in cases of spontaneous periodontitis. When hyperreactivity of organism is observed, the changes of indicators of lipid peroxidation, medium molecular peptides and prostaglandins promote strengthening of necrotic processes, and in cases of hyporeactivity they boost their slowing down that in both cases leads to delay of reparation in healing of an artificial mucous-bone wound.

Keywords: spontaneous periodontitis, reactivity of the organism, wound healing, biochemical parameters.

Published: January 2022

The present study investigated the chemical profile, toxicity, and anti-anaemic activity of Rubia tinctorum root aqueous extract against phenylhydrazine induced hemolytic anaemia. Phenolic compounds were analyzed by LC-ESI-MS/MS; acute toxicity test was evaluated by administering a single dose of 2,000 mg.kg-1 of the extract; anaemia was induced by administration of 40 mg phenylhydrazine by intraperitoneal injection for 2 days. Moreover, the anti-anaemic activity was evaluated by measuring the haematological parameters of rats treated with iron and aqueous extract for 15 days. The LC-ESI-MS/MS analysis results revealed the presence of 31 phytochemical compounds, among them, citric acid was found as the most abundant. No signs of toxicity or death were recorded, indicating that the LD50 of R. tinctorum root extract is higher than 2,000 mg.kg-1. Furthermore, the aqueous extract increased red blood cell levels by 69.82 and 71.67 % in the groups treated with 200 and 400 mg.kg-1 of the extract, respectively. Besides, a significant increase in hemoglobin from 12.05 ± 0.15 to 12.9 ± 0.52 g.dL-1 was noted in rats treated with 400 mg.kg-1 of extract. Thus, the data indicate that the root extract could be considered a natural source for the treatment of anaemia.

This article is devoted to the study of the main trends in the development of the oil and gas market, as well as the transfer of state support aimed at the implementation of Arctic oil and gas projects. The analysis showed that 2020 turned out to be extremely difficult for the oil and gas industry as a whole. The volumes of oil and natural gas production and consumption decreased, and due to a reduction in revenue, large domestic companies began to save on exploration drilling. Given the high level of «depletion» of oil reserves in traditional fields, with an increase in demand, in the short term, domestic oil companies will not be able to quickly increase production volumes and take advantage of favorable market conditions.

The current stage of socio-economic transformations has shown that the main competitive advantage of countries and regions is associated with the quantity and quality of human resources. In such a situation, the issue of creating conditions that ensure the life of people and the development of human potential becomes of paramount importance. In this context, the special significance of the social infrastructure of the region (the functioning of which is aimed at meeting the most important needs of the population) is due to its ability to provide and expand opportunities for the development of human potential, thereby affecting the socio-economic development of the region as a whole. However, for a long time, the regions' capabilities for main-taining infrastructure facilities were limited, the degree of wear and tear of fixed assets increased, the direction of using social infrastructure facilities changed, and the volume and quality of services provided decreased. De-stimulation of the processes of renewal of social infrastructure has led to a decrease in the potential for its development.

ECONOMIC CONSCIOUSNESS AS A MECHANISM FOR THE DEVELOPMENT OF ENTREPRENEURSHIP
Authors:   Kutafin Moscow State Law University (MSAL), Moscow, Russia, Romanenko Nadezhda Yu.
Published: January 2022

In modern realities, physical and mental activity come to the fore, allowing the entrepreneur to maximize the use of available resources, both his own and those presented by the environment. Only in the presence of these psychological characteristics, the leader is able to manifest an ontological essence that allows him to achieve high efficiency of the subordinate team. The article substantiates the need to understand that economic consciousness is not a substance di-vorced from the world and everything earthly. On the contrary, the principles of clarity, comprehensibility, and objectivity should be laid at the basis of economic thought in any of its manifestations. Professionalism in entrepreneurial activity must be based on universal standards. No one has canceled the originality and creativity of thinking, and it is they who become the basis of modern economic thinking. But completely ignoring the spiritual foundations, traditions or opposing their ac-tivities to them is fraught with transition (as Darth Vader said) “on the dark side of economic consciousness”. Separately, the author highlights such a concept as the ethics of an entrepreneur, determined by the norms and standards of a cultural society. The development of economic thinking of any person is impossible without practice. One theory or even simulators, simulators can not do. Consciousness and thinking are formed only through active behavior. By expanding the range of interests in professional activity, a person is forced to learn new things, be-comes richer not only in educational or economic terms, but also morally and socially. Through active actions, there is the development of intelligence, the formation of experience and wisdom, the knowledge of the laws of society and being.

The goal of this article is to outline and to analyse the key challenges to be faced by the Polish energy market, as it is only at the beginning of the energy transition process. The dynamics of energy policy adaptation process to the challenges of the energy security dimensions, in the face of the energy and climate policy set by the European Union and the expected transformation goals, may cause the growth of the energy security deficit both on a national and regional scale. Given the centralized model of energy infrastructure management, reliance of domestic generation capacity on conventional sources and insufficient development of cross-border networks, Poland is particularly exposed to a security deficit related to the transformation of its energy system, which may also negatively affect other countries in the East- Central Europe region. Using program documents and sector analyses, the article analyses possible strategies for ensuring energy security, setting the issues in the context of the specificity of the Polish energy sector and opportunities for development of regional cooperation between Central and Eastern European countries. As a result, the article reveals an assessment which shows an insufficient recognition by Poland both the external and internal factors determining the pace and direction of energy modernization, as well as a failure to adapt energy policy objectives to the specifics of low-carbon energy sources and the potential provided for by regional energy markets.

Published: January 2022

The article presents numerical calculation analysis in the scope of determining thermal conductivity coefficient λeq [W/(m·K)] of thermally heterogeneous hollow bricks of thermally heterogeneous structure (a combination of structural material with thermal insulation material). Numerical calculations were conducted by means of professional software TRISCO-KOBRU 86, serving thermal circulation analysis in a 2D field in stationary approach. The analyzed hollow wall bricks may be used, for instance, as a structural layer of layered outer walls of a building. In the article also the results of the Uc thermal conductivity coefficient calculations for double-layer walls with the use of the analyzed hollow wall bricks are presented in regard to thermal requirements.

Post-traumatic hydrocephalus (PTH) is a field and disorder less explored in neurosurgery though we see many cases. The commonest causes in our set up includes head injury for which people have undergone decompressive craniectomies, severe head injuries with raised ICP. We did a clinical analysis on 23 cases in a period of 3 years duration from 2018 -2021. We did Evd in few cases for emergency purposes when there was decerebration and we went ahead with VP shunt in all the patients who had gross ventricular dilatation. We have projected our analytical report in these cases. METHODS A retrospective study was conducted in the Department of Neurosurgery in Sri Ramachandra medical college. The clinical outcome of patients diagnosed with PTH was studied. These cases were treated by surgery. The stastical analysis along with cause of the hydrocephalus with the outcome in pre and postoperative period were studied. RESULTS Among the 23 patients studied 82% were males. Road traffic accident was the main cause of injury. The other main cause was a fall from height. Assault was another reason for head injuries which we recorded. We found all road traffic accidents were only because of bike riders either pillion or the people driving the vehicle. . Craniotomy was done in 50 % of the patients, 90 % of the patients recovered who had a gcs of 13 to 7. People with gcs lss than 7 were intubated recovery rate was 7.5 %. . There was 100%mortality because of primary head injury in all the patients who had brain stem contusions with dilated pupil. CONCLUSIONS Trauma to head and who were operated had the highest incidence of post tramatic head injury. Smaller the decompressive craniectomies had symptomatic post traumatic head ache with post traumatic hydrocephalus.. CT scan of the brain is considered the choice of investigation toearly diagnose PTH.we even analysed the ct scan and found when there was periventricular lucency the patient outcome after VP shunting is good.
