Published: December 2022

Приведены результаты теоретических исследований кинетики процессов биохимического окисления органических загрязнений сточных вод микроорганизмами активного ила. Показано, что величину среднедействующей удельной скорости окисления органических загрязнений сточных вод активным илом аэротенка-вытеснителя можно определить, используя теорему о среднем значении непрерывной функции f(L), интегрируемой в некотором промежутке изменения ее переменной от Lн до Lк. Интегрированием уравнения Михаэлиса–Ментен получена математическая модель, базирующаяся на фундаментальных закономерностях ферментативной кинетики, описывающая процесс биологического окисления органических загрязнений в аэротенке-вытеснителе. Использование предлагаемых уравнений позволит определять среднедействующие значения удельных скоростей окисления различных органических загрязнений (БПК, нефтепродуктов, ПАВ, фенолов и др.), расчетную продолжительность аэробных процессов и тем самым оптимизировать процессы проектирования и эксплуатации сооружений биологической очистки сточных вод в аэротенках-вытеснителях.

The results of theoretical studies of the kinetics of the processes of biochemical oxidation of organic wastewater pollution by activated sludge microorganisms are presented. It is shown that the value of the average effective value of the specific rate of organic wastewater pollution oxidation by the activated sludge in a plug flow aeration tank can be determined using the theorem on the average value of the continuous function f(L) integrated in a certain range of its variable from Lн to Lк. By integrating the Michaelis–Menten equation, a mathematical model was obtained based on the fundamental regularities of enzymatic kinetics that describes the process of biological oxidation of organic pollutants in a plug flow aeration tank. The use of the proposed equations will provide for determining the average effective values of the specific oxidation rates of various organic pollutants (BOD, oil products, surfactants, phenols, etc.), the estimated duration of aerobic processes; and thereby, optimizing the design and operation of biological wastewater treatment facilities in plug flow aeration tanks.

The changes experienced in technology due to the third industrial revolution have over the years contributed immensely to the development of efficient devices and systems. As a result, solutions have been provided to challenges encountered in the heating industry. However, higher efficiency and better performance has undoubtedly been highly sort after. This paper presents the complete industrial development of a new system of a microwave device for use in S-band networks (2.45 GHz ISM band in this application): a vector network analyzer (VNA). The VNA, which is designed based on the six-port measurement principle, provides accurate measurements of both magnitude and phase of the load reflection coefficient. The device is designed to have high power handling capabilities and works under the full operating conditions of high-power microwave generators. Initial measurements show that the device perform stable and can perform temperature-independent measurements over protracted periods. The system is suited for on-line monitoring and control of network parameters in industrial waveguide applications..
DETECTION AND CLASSIFICATION OF VEGETATION AREAS FROM RED AND NEAR INFRARED BANDS OF LANDSAT-8 OPTICAL SATELLITE IMAGE
Authors: NALLAPAREDDY Anusha
Published: December 2022

Detection and classification of vegetation is a crucial technical task in the management of natural resources since vegetation serves as a foundation for all living things and has a significant impact on climate change such as impacting terrestrial carbon dioxide (CO2). Traditional approaches for acquiring vegetation covers such as field surveys, map interpretation, collateral and data analysis are ineffective as they are time consuming and expensive.  In this paper vegetation regions are automatically detected by applying simple but effective vegetation indices Normalized Difference Vegetation Index (NDVI) and Soil Adjusted Vegetation Index (SAVI) on red(R) and near infrared (NIR) bands of Landsat-8 satellite image. Remote sensing technology makes it possible to analyze vegetation cover across wide areas in a cost-effective manner. Using remotely sensed images, the mapping of vegetation requires a number of factors, techniques, and methodologies. The rapid improvement of remote sensing technologies broadens possibilities for image sources making remotely sensed images more accessible. The dataset used in this paper is the R and NIR bands of Level-1 Tier 1 Landsat-8 optical remote sensing image acquired on 6th September 2013, is processed and made available to users on 2nd May 2017. The pre-processing involving sub-setting operation is performed using the ERDAS Imagine tool on R and NIR bands of Landsat-8 image. The NDVI and SAVI are utilized to extract vegetation features automatically by using python language. Finally by establishing a threshold, vegetation cover of the research area is detected and then classified.

s, a Bi2Se3 film with the smallest root mean square roughness (Rq) and the lowest electron density was grown at T
s = 120 °C. In the optimized growth condition, Bi2Se3 epitaxial films with 3−85 quintuple layers (QL: 1 QL ≈ 1 nm) were grown. In unpolarized Raman spectra, the positions of A

g-modes shifted to the low wavenumbers at film thickness below 10 QL. The polarized Raman spectra showed that the depolarization ratio ρ also changed with film thickness. The change in ρ was more significant than the change in the position shift. This indicates that the measurement of ρ is an effective method to evaluate the thickness of Bi2Se3 ultrathin films.
Spatio-temporal description of the origin of optical-near-field interactions
Authors: Yazaki Tomoaki , Kobayashi Kiyoshi , Ishikawa Akira
Published: December 2022

Optical-near-field interactions occur via virtual photons that are non-resonant with the nanomaterials. Since the virtual photon exists only on a timescale shorter than the timescale of the interaction between the propagating light and the nanomaterial, the optical-near-field interactions exhibit non-Markovian temporal properties. We propose the spatio-temporal description of excitation transfer dynamics via virtual photons, and clearly show that the spatial properties of optical-near-field interactions at a short distance originate from the non-Markovian temporal properties on short timescale. Thus, the origin of optical-near-field interactions can be understood using the spatio-temporal description of the non-Markovian dynamics.

Authors: Wang Mengyue , Maekawa Manaka , Shen Man , Liu Yuanjia , Arifuku Michiharu , Kiyoyanagi Noriko , Inoue Taiki , Kobayashi Yoshihiro
Published: December 2022

We experimentally investigated the effect of carbon-containing reactants (C2H2) on healing the defects in single-walled carbon nanotubes (SWCNTs) by thermal processes at high temperatures (∼1100 °C). Introducing C2H2 notably improved the crystallinity of healed SWCNTs compared with the thermal process in Ar ambient without C2H2. The defect healing rate increased with increasing C2H2 partial pressure, and the healing effect of C2H2 was more remarkable for relatively thinner SWCNTs (<1.1 nm). Combined with the relevant theoretical work reported previously, we propose a healing model in which C2H2 helps to heal the vacancy defects and increases the healing rate at high temperatures.

Published: December 2022

The results of bottom trawl surveys and simulation assessments indicate relative stable state of saffron cod stock in the southwestern part of the Bering Sea. According to model calculations the total stock of saffron cod in 2020 amounted to 163,8 thousand tons. The analysis of the Danish seine catches showed that saffron cod forms commercial concentrations mainly in the Litke Strait and the Gulf of Corfu. In 2010-2020 the total catch of the saffron cod ranged from 4,3 to 14,5 thousand tons averaging 8,5 thousand tons. The most effective fishing by Danish seine is carried out in September and October with average catches of 9,1 and 11,5 tons per day respectively.
Аrtificial intelligence technologies in aquaculture
Authors: Cherdantsev V. P. , Svechnikova T. M. , Tronina M. V.
Published: December 2022

The paper presents an overview of foreign practices of using artificial intelligence (AI) technologies in fish farming or aquaculture. It is noted how effective the management of a fish farm can become if there is access to new information that would have gone unnoticed without the use of artificial intelligence. Taking into account the fact that the pace of development of aquaculture in Russia is very insignificant and significantly lags behind foreign analogues, and also taking into account the active processes of digitalization of all spheres of the economy in our country, it seems that a review of foreign practice of using AI in aquaculture will further create its own resource base in the direction of AI for the agro-industrial sector.

Published: December 2022

Russian research into the possibility for fishing of Antarctic crabs was started in 2010 in the South part of Atlantic Ocean (Anosov, 2012). Subsequently appeared the idea to study the possibility of crab fishing in the Pacific sector of Antarctica, where no one had previously conducted such studies, but it was known about by-catch of potentially commercial species of crabs to the longline (Anosov, 2015). The realization is came in the season of 2018/2019, when the first stage of the research program was completed. The purpose was to establish the species composition and the primary determination of the distribution of crabs in the area 88.2 and in the area 88.3. Crab fishing was carried out with the help of conical pots, which were set in 120 pieces in order. The average stagnation time was 32 hours 42 minutes. 3 species of crabs were occurred. Only one can be considered as potentially commercial species – Neolithodes yaldwini. As a result of these studies, data on the species composition, morphological parameters, bathymetric and spatial distribution of Antarctic species of crabs of the family Lithodidae were obtained for the first time.

Authors: Kharenko E. N. , Yarichevskaya N.  N.
Published: December 2022

The purposeof this study is a comparative analysis of data on the yield of surimi minced meat from some types of cod fish based on the results of experimental and control work (ECW).

Methods used:experimental and control work was carried out according to the «Methods for determining the consumption rates of raw materials in the production of products from hydrobionts». Calculations of experimental and control work results were performed using software for processing the results in the production of frozen surimi minced meat. 12 ECW were carried out (4 ECW for each type of fish), while 22,150 kg of pollock, 33,400 kg of far eastern goby and 20,650 kg of saffron cod were directed to the production of surimi minced meat.

Novelty:on the basis of the research and development work carried out, data were obtained on the yield of surimi minced meat from cod fish, made on a modern line in the conditions of a coastal enterprise. It has been established that the yield of surimi minced meat from pollock according to the results of ECW is on average 2,0 % higher than the values obtained for the far eastern goby and saffron cod.

Result:an analysis of the modern production of surimi minced meat was carried out, which indicates a trend towards expanding the raw material base for its production due to fish with a high fat content and dark meat color, including warm-water ones; objects of pond aquaculture; low-value and small-s ized fish, which to a certain extent helps to reduce the cost of the finished product. However, pollock 35–45 cm in size is the most preferred raw material for obtaining high-quality «surimi» with a high yield, high degree of whiteness and the ability to form a strong gel.

Practical significance:the results obtained allow us to determine current trends and prospects for the use of pollock for the manufacture of fish food products of deep processing. The unique properties of surimi minced meat and the increase in its production will expand the range of easily digestible fish protein products for various population groups.

convergence criteria and the impact of convergence indicators on the exchange rate volatility inner the WAEMU
members States. From that end we have conducted the empirical analysis of budgetary convergence in the WAEMU zone
by using variables such are: expenditure, incomes and budgetary balances. In order to reach our goal, we have adopted
the methodology used by Barro et Salai-Martin (1992) which methodology is implemented by the European Union
through the work of Villien et al. (2003). This methodology is consisted of following in the course of the timing an indicator
of variable dispersion which may stand as a typical margin or the variance. The results show a global trend to budgetary
variables convergence. And then, we have assessed the different indicators of sigma convergence on the profitable
exchange rates differential in the WAEMU zone. The model used has revealed the existence of a mechanism of correcting
error between the desired exchange rate observed in the zone.

A Review of Current-Limiting Control of Grid-Forming Inverters Under Symmetrical Disturbances
Authors: Fan Bo , Liu Teng , Zhao Fangzhou , Wu Heng , Wang Xiongfei
Published: December 2022

Grid-forming (GFM) inverters are recognized as a viable solution to increase the penetration of renewable energy in bulk power systems. However, they are physically different from synchronous generators in terms of overcurrent capability. To protect the power semiconductor devices and support the power grid under severe symmetrical disturbances, the GFM control systems should be able to achieve the following requirements: current magnitude limitation, fault current contribution, and fault recovery capability. Various current-limiting control methods are reported in the literature to fulfill these goals, including current limiters, virtual impedance, and voltage limiters. This paper presents an overview of those methods. Emerging challenges that need to be addressed, including temporary overcurrent, unspecified output current vector angle, undesired current saturation, and transient overvoltage, are pointed out. Comparative simulations are conducted to demonstrate the performance of different methods under grid voltage drops and phase jumps. Finally, open issues of current-limiting control methods for GFM inverters, including transient stability assessment, voltage source behavior under overcurrent conditions, and windup of voltage controllers, are shared.

A Self-Solving Approach to Ordinary Differential Equations
Authors: Kennedy Stephen
Published: December 2022

A novel approach for numerical analysis of ordinary differential equations (ODEs) is shown to cause an arbitrary initial function to conform to the solutions of sample ODEs.   By way of examples, the method is shown to consistently converge upon the solutions of initial value problems for two different step sizes. Further study is needed to determine if the method is stable for increasing smaller step sizes. Some advantages of this method are its simplicity, new approach to solving problems, and its potential to be applicable to a wide range of ODEs and partial differential equations that are useful in STEM fields.

Obesity is associated with increased sensitivity to pain, including neuropathic pain (DN).The objective of this study is to determine the prevalence of DN in obese patients, to assess its impact on the quality of life and to identify the factors associated with it. This is a prospective and descriptive study conducted over a period of 4 months. All patients with BMI over 30 kg/m2, non-diabetics were included. The evaluation of neuropathic pain was made by the DN4 score. The visual pain scale was calculated. Quality of life was assessed using the SF-12 score. Statistical analysis was performed using SPSS 26. A total of 111 patients were included. The average age was 44.79 years old. The majority were women. The average BMI was 38.69 kg/m2. The prevalence of neuropathic pain was 59.1%. The average VAS was 4.32. Physical quality of life was impaired in 66.7% of patients and 71.4% had an impairment of mental life. In univariate analysis, neuropathic pain was more common in women, in older subjects, in cases of prediabetes, in cases of vitamin D deficiency and in patients with impaired physical and mental quality of life. The Spearman correlation study had shown that the DN4 Score was positively correlated with pain VAS, and negatively correlated with physical quality of life and mental quality of life. DN is common in obese patients. It is responsible for a significant impact on the quality of life, hence the importance of detecting and treating it.

Introduction: Androgen deprivation therapy is the mainstay of systemic treatment for metastatic prostate. However, the majority of patients progress to CRPC. The aim of this study is to identify factors that predict castration resistance in men with locally advanced or metastatic prostate cancer treated with first line ADT. Methods: This is a retrospective and analytical study including 46 patients treated for advanced or metastatic prostate cancer with first-line ADT at the Military Hospital Mohammed 5 of Rabat (HMMV) between November 2013 and July 2018 (a period of 5 years). The elements analyzed were sociodemographic, clinical, patient history, biological and radiological data. Results: Predictive factors for castration resistance in our sample are: 1) A high-risk stage according to the LATITUDE criteria. 2) High initial PSA. 3) PSA nadir (PSAn) > 1.17 ng/ml. 4) Elevated PAL at diagnosis > 129 IU/L. 5) Short time to reach PSAn ≤ 9 months. Conclusion: The risk factors predictive of early resistance to first-line hormonal therapy in patients with metastatic prostate cancer in our series were similar to those described in the literature. We advocate early treatment with hormonal chemotherapy in any patient with metastatic prostate cancer who has any of the elements identified in our study.
A Nimble Review of the Development Path of Sierra Leone Stock Market
Authors: Bonga Wellington Garikai
Published: December 2022

Economies with more active stock markets develop faster over successive decades. Such development remains attainable even after adjusting for various other factors underlying economic growth. Sierra Leone is one country whose stock market is now more than a decade old but remains poorly active. The number of listings as well as participation in the stock market remains low and insignificant. The study made a light review of the development path of the stock market in an effort to identify the derailing issues and suggesting ways to resolve. Through the review, it was obtained that there exist combinations of factors hindering the growth of the stock market. Inadequate support from the government has been identified, the privatisation concept was never implemented to the expected level, nature of business in the economy being mainly family-oriented and single proprietors, low levels of awareness of the general populace to issues of stock exchanges, limited participation by foreign investors, and high levels of corruption all are impacting factors. Significant reforms have to be made in the regulatory environment. Privatisation journey should be pursued effectively to improve listing by large firms. Foreign participation in the stock market elevated to some significant levels. The economy should continue to address issues of corruption so as to minimise its impact to institutional development. Public awareness should be enhanced to improve stock market participation by natives. Policies that promote foreign direct investment should be implemented. Management of political climate remains crucial for investors to have confidence and trust in their investments thereby attracting more for further development. Policy makers should walk the talk and demonstrate highest levels of commitment.

The success of a company's target market is heavily dependent on purchasing decisions. The aspect that influences consumers' purchase decisions is the brand image. The buying decision is substantially influenced by brand perception. In this instance, brand image is significant for resellers as business players. Consumer service quality is another consideration. Quality of service is a manner of conducting business that tries to make ongoing quality improvements to the company's operations, products, and services. This type of research is quantitative, applying multiple linear regression techniques using moderating variables. The population of this study was all 150 customers of the Compassnyaban shoe store for the period July 2021 to June 2022 using the census method. The results showed that the brand image of Compass shoes found that Compass shoes used ideal raw materials. Compassnyaban shoe store's service quality was found to be responsive through complaint handling. The decision to purchase Compass shoes found that customers chose Compass shoes because of their trusted quality and quality. The result of this study is that brand image influences the purchasing decisions of Compassnyaban shoe store customers. The results showed that service quality did not affect the purchasing decisions of Compassnyaban shoe store customers. Demographic factors (gender, age, education) as moderating variables strengthen the influence of brand image on purchasing decisions at the Compassnyaban shoe store in Malang. Demographic factors such as education are the moderating variable that strengthens the relationship between brand image and purchasing decisions. Demographic factors (gender, age, education) as moderating variables strengthen the negative effect of service quality on purchasing decisions at the Compassnyaban shoe store in Malang. Demographic factor as education is the moderating variable that weakens the relationship between brand image and the decision to buy Compass s

Physical fitness and weight in young children are important indicators of health status. Literature has shown that fatness and physical fitness are highly intertwined; considering the two together is important as they influence each other. The aim of this study was to investigate the physical fitness levels and weight status of Grade 1 children (N=184) from two schools in Cape Town, South Africa, as well as differences in physical fitness and weight between boys and girls. A quantitative study design was applied. Physical fitness skills were evaluated by measuring five components: cardiorespiratory fitness, muscular strength, agility, flexibility and coordination. Children’s height and mass were measured to determine their Body Mass Index (BMI) and the International Obesity Task Force (IOTF) cut-offs were used to establish under- and overweight classifications of the children. Boys performed better than girls in the standing broad jump, shuttle run and throwing, whereas girls performed better in the flexibility test. Of the children, 84% were classified as normal weight, 11% were overweight and 5% were obese. The children in this study were relatively fit compared with children in other provinces in South Africa; however, their fitness levels can still be significantly improved.
value of volunteering in pursuit of improved employability in the sport for development sector: A case study in Sub-Saharan Africa

Volunteers are integral to the delivery of sport at a community level and the main implementers of many sport for development (SfD) programmes. However, research into this phenomenon in the global south is lacking. This exploratory study investigated the value of volunteering in pursuit of improved employability in the SfD sector through a case study analysis. Participants were traced from 67 ex-volunteers who had volunteered at an SfD organisation delivering programmes in impoverished communities in South Africa, Namibia and Zambia between 2012 and 2020. Thirty-eight were recruited for the study – 23 from South Africa, 10 from Namibia and 5 from Zambia, and they completed a questionnaire as part of sequential multi-method approach. Twelve ex-volunteers, three in-country managers and two managers from the organisation’s head office were interviewed. The volunteering experience was found to have contributed to a 65% employment rate and a high level of perceived employability, and met expectations of personal development, networking, active citizenship and social validation. It is against the reality of youth unemployment and the quest for survival that the role of volunteering found special meaning as a pathway to socio-economic empowerment and delivered on the aspirations and outcomes of volunteering in an SfD organisation.
PUNK E HIP-HOP COMO MOVIMENTOS SOCIAIS?
Authors: Turra Neto Nécio
Published: December 2022

Abordo aqui duas culturas juvenis transterritoriais – Punk e Hip-Hop –, problematizando a possibilidade de considerá-las como novos sujeitos políticos, territorializados no lugar. Inicio o texto situando o conjunto de preocupações, que tem direcionado minha atenção: as relações entre sociabilidade e cidade, no espaço-tempo. Punk e Hip-Hop colocam-se como possibilidades de identificação para jovens, situados em diversos lugares da cidade, construírem suas redes de sociabilidade e territorializarem-se na cidade. Uma territorialização que não é indiferente à cidade concreta em que se realiza. Assim, argumento que a consideração do Punk e do Hip-Hop como movimentos sociais só pode se dar a partir de parâmetros muito precisos. Para referendar o argumento, reconstruo a trajetória histórica de ambas as culturas juvenis, do mundo ao lugar, tomando como referência uma cidade média paranaense. Para finalizar, apresento uma reflexão, ainda preliminar, sobre a dialética socioespacial, tema para o qual estudos dessa natureza podem trazer alguma contribuição.
