Authors: Xu Yue , Xia Guanghao
Published: September 2023

In this paper, we firstly propose an art style classification system based on the RNN model to study the development of the art industry, and continuously fine-tune this white noise image according to the long and short-term memory network and gated recurrent unit network until it makes this white noise image similar to the artwork image style, and the ink painting image feature extraction is mainly studied from the recurrent neural network based ink style feature extraction and the overall nested edge based The two aspects of brushstroke feature extraction based on overall nested edge detection are studied. Then, based on the art industry and big data, the ink painting style classification system is constructed, and the effectiveness of the system is verified by model art classification effect analysis. The results show that the RNN performs well on the face dataset, where the accuracy of multiple classifications up to 10 categories is above 85%. This indicates that the RNN model in this paper can maintain good performance in the ink painting art classification task.

Authors: Lu Zhenjun , Chen Jiadong , Zhang Yufeng
Published: September 2023

This paper firstly analyzes the urban residential electricity load characteristics and extracts residential electricity load data through a non-intrusive electricity load monitoring framework with electricity load characteristics. Secondly, the gray Verhulst model is improved by using function transformation and residual correction to further improve its prediction accuracy. Finally, a prediction example analysis is carried out for the electric load under urban residential electricity security. The results show that the maximum prediction error of the improved gray Verhulst model is 2.28%, which is 1.34 percentage points lower than the 3.62% of the genetic algorithm GM(1,1) model. This indicates that the prediction of urban residential electricity security can be achieved using the improved gray Verhulst model.

Ecological urban conurbation design based on perceptual machine model
Authors: Li Jing
Published: September 2023

Since cities are areas with more serious ecological damage, it is of practical significance to construct ecological city development strategies. This paper first focuses on two levels: general pattern and spatial elements, and focuses on the methods and strategies of eco-city design under the bird-friendly orientation of spatial elements. Second, the degree of correlation between the two systems is determined using the theory of perceptual machine model, and the degree of impact is prioritized in order to identify the key influencing variables of the mutual coupling and coordination between urbanization and the ecological environment. Last but not least, the complete evaluation functions of urbanization and ecological environment were produced by integrating the standardized values of all evaluation indexes. The weights of each indicator were determined using the entropy weight technique. The findings indicate that city H’s overall level of urbanization growth and ecological environment development both exhibit upward trends year over year. The range of coupling coordination degree is between 0.3025 to 0.8975, and the type of coupling coordination changes from moderate dysfunctional decline to high-quality, coordinated development. The eco-city design plan remedies suggested in this study change the industrial structure adjustment process, boost macro-government supervision, and raise public awareness of environmental protection.
Wide Range Si3N4 Optical Sensor Using Cascaded Mach-Zehnder Interferometer Coupled Ring Resonator
Authors: Hu Yuzhu
Published: September 2023

A cascaded MZI-coupled ring resonator (CMCR) optical sensor based on silicon nitride waveguide is proposed. The sensor is composed of a large size microring and a bus waveguide coupled with the microring for four times. The three-segment bus and the microring waveguide between the four coupling regions form three MZI of the same size, forming a three-stage cascaded MZI. The resonant effect of the cascaded MZI transforms the smooth comb spectrum of the microring into a V-shaped comb spectrum, expands the effective free spectral range of the ring resonator, and realizes the cascaded MZI-coupled microring sensor with a large measurement range. For the cascade MZI-coupled microring with a radius of 100μm, the effective free spectrum range is 53.7nm, which is more than 24 times larger than that of the all-pass microring of the same size. The refractive index sensitivity is 339.49 nm RIU/and the detection limit is 2.95 × 10−5 RIU. these excellent properties prove the feasibility of cascaded MZI-coupled microring structure for large measurement range sensing, and are expected to be used in large refractive index range sensing applications in the future.

The upgrading of the energy industry structure will certainly affect the development of the environment, and the study of the impact of export restrictions is an inevitable trend. This paper firstly establishes time series and panel series models based on Kuznets curve. The concept and mathematical derivation of environmental Kuznets curve are analyzed. The green Solow model is selected to extend the exogenous technology of Solow model to the field of pollution reduction and establish the relationship between energy industry upgrading and environmental development. Secondly, the relationship between economic development and resource consumption and environmental pollution is analyzed based on the concept of decoupled development. Finally, the relationship between total energy consumption and total carbon emission and economic growth is investigated. The carbon emission coefficient is 0.712, the oil emission coefficient is 0.576, and the natural gas emission coefficient is 0.437. The carbon emission of total energy consumption is also in the left half of the inverted U-shaped curve, i.e., the carbon emission is still rising as the economy grows.
Undermining the legitimacy of the news media: How Swedish members of parliament use Twitter to criticise the news media
Authors: Liminga Agnes , Strömbäck Jesper
Published: September 2023

Over the last decade, the news media increasingly seem to have become a target for politically motivated criticism seeking to delegitimise the news media. The prevalence of delegitimising media criticism is, however, unclear. Hence, the purpose of this study is to investigate the extent to which Swedish members of parliament (MPs) engage in delegitimising media criticism on Twitter, the party distribution of those engaging in such media criticism, and the targets and expressions of such media critique. Among other things, the findings show that when MPs tweet about the news media, they are more likely to be critical than supportive, and that a clear majority of tweets that are critical toward the news media contain delegitimising media criticism. Moreover, the results show that MPs from the political right – in particular the Moderate Party and the Sweden Democrats – are most active in tweeting delegitimising media criticism, and that the most common target is public service media.

Published: September 2023

This article presents the results of a study of the possibility of using cabbage and applesauce in the produc-tion of bakery products. For research, various dosages of cabbage (3, 6, 9, 12%) and apple (5; 7.5; 10; 12.5%) puree were selected. Studies have been carried out on the organoleptic and physico-chemical parame-ters of raw materials, semi-finished products and finished products. In the experimental part, the influence of cabbage and apple puree on the properties of dough and finished products (a bun made from premium wheat flour) was studied. An increase in acidity and dough volume was revealed when both cabbage and apple pu-ree were added. There is an increase in volume yield and porosity of finished products. The mass fraction of fiber in products increases, shrinkage decreases. As a result of the research, the optimal dosage of cabbage (6%) and apple (7.5%) puree was identified, a fruit and vegetable mixture was compiled and introduced into the bun recipe. The calculation of the chemical composition, calorie content and nutritional value of the con-trol and optimal sample of the bun was carried out. According to the results of calculations, it was found that with the introduction of fruit and vegetable mixture into the recipe of the bun, the content of indigestible car-bohydrates increases by 2 times, the amount of minerals increases slightly, the caloric content of the product decreases (by 6%), as well as the amount of fat, starch, dextrins.

The article shows the results of research on the development of the formulation and technology of stuffed rabbit meat enriched with psyllium powder. In the control recipe of the meat-growing semi-finished product, pork in minced meat was replaced with rabbit meat and part of rice with 1% psyllium powder. The vitamin and mineral composition of rabbit meat is significantly superior to other types of meat. Rabbit meat is rich in vitamins B6, B12, PP, contains a lot of iron, phosphorus, cobalt, manganese, fluorine and potassium. Rabbit muscle tissue has a low content of sodium salts, which makes rabbit meat a low-calorie product. Rabbit meat gives the product dietary properties, and when the product is enriched with psyllium powder, its beneficial properties increase doubly. Psyllium contains a large amount of organic fiber, it is an enterosorbent, a prebiotic with adsorbing properties. Psyllium also has a positive effect on the microflora of the gastrointesti-nal tract, increasing the number of beneficial bacteria Lachnospira, Roseburia and Faecalibacterium, pro-ducers of essential intestinal butyric acid. Eating foods containing psyllium husks lowers cholesterol and im-proves blood pressure, as psyllium absorbs fats and removes them from the body. We believe that a meat product enriched with psyllium powder is relevant for the diet of people suffering from "bad" cholesterol, obesity, problems with the gastrointestinal tract, as well as for the diet of people with diabetes and athletes.

Many clone rootstocks of apple trees obtained as a result of long-term breeding work in the Michurinsky State Agrarian University have a genetically determined ability to biosynthesis of anthocyanins. Pigments of this group are widely distributed and synthesized by a large number of plants, especially in stressful situa-tions. For the most part, pigments accumulate in mature fruits. Many clonal rootstocks of apple trees ob-tained in Michurinsky GAU (Paradizka Budagovsky, 54-118, 62-396, 70-20-20, 98-7-77 and others) synthe-size pigments in all vegetative and generative parts – «red-leaved». During the production of planting mate-rial, a large amount of waste is generated in the form of annual shoots of clonal apple rootstocks, which are considered as raw materials for the production of anthocyanin food dyes. A qualitative analysis of anthocya-nins of clone rootstocks of apple trees selected by the Michurinsky State Agrarian University was carried out in the laboratory conditions of the TSTU, and it was found that it corresponds to the composition of anthocy-anin dyes produced in the country from fruits and berries, and the main pigments of clone rootstocks of apple trees are cyanidin and delphinidin.

Title: Clinical utility of BRAF and pTERT mutations in precision management of Papillary thyroid cancer
Authors: Shabbir Hamid , Imran Muhammad , Naeem Muhammad
Published: September 2023

Papillary thyroid cancer (PTC) is the most prevalent and indolent thyroid cancer, but still, around 20% of cases will develop regional recurrence or distant metastasis. Isolated or coexistent BRAF V600E and pTERT mutations in thyroid cancer are associated with poor clinical outcomes. The prior knowledge of BRAF V600E and pTERT mutation may help to identify the cases that may recur or become refractory to standard radioactive iodine treatment. Such cases could be treated initially with complete disease eradication through extensive surgery followed by maximum permissible high-dose radioactive I-131 ablation and vigilant follow-up. Conventional risk assessment coupled with genotype-based risk assessment can help in the precise management of aggressive thyroid cancers.
ЦЕНТРАЛЬНІ ПОСТАТІ ТА ПОДІЇ УКРАЇНСЬКОЇ ІСТОРІЇ У СВІТЛІ КОНТЕНТ-АНАЛІЗУ УКРАЇНСЬКИХ ІСТОРИЧНИХ YOUTUBE-КАНАЛІВ з 2014 до 2022 року

Published: September 2023

Мета дослідження – на основі опрацювання історичних роликів, розміщених на провідних українських історичних YouTube-каналах, визначити історичних героїв та події, які є топовими серед українців упродовж 2014 – 2022 рр. Методологія дослідження ґрунтується на комплексному підході, в основу якого покладено використання спеціальних комп’ютерних методів, які до цього саме так не застосовувалися. Використовувалися методи, пов’язані з комплексним мережевим аналізом (CNA), за допомогою якого реляційна база даних, що містить інформацію про найпопулярніших героїв, події та теми в українських історичних відео YouTube, була зображена у вигляді графіка, а найбільш значущі персонажі та мотиви були з’ясовані за допомогою вимірювання центральності (як вершини графа). Алгоритми Louvain Community Detection і Clauset_Newman_Moore були використані для виділення зв’язків між темами та контекстом їх створення (датою). Наукова новизна полягає у з’ясуванні популярних історичних героїв серед користувачів українських історичних YouTube каналів шляхом застосування новаторської комп’ютерної методики. Висновки. Сьогодні YouTube – це не просто платформа для розміщення відповідного відеоконтенту, а  соціальна мережа, яка виступає майданчиком для навчання, спілкування, обміну ідеями, поширення важливої інформації. Упродовж 2014 – 2022 рр. на українських YouTube- каналах історичної тематики з’явилася низка цікавих та важливих фільмів і роликів, присвячених  висвітленню українського погляду на власну історію, яка упродовж десятків років старанно приховувалася або ж переписувалася колоніальними режимами. У результаті проведеного дослідження, шляхом застосування новаторської комп’ютерної методики, авторами було з’ясовано, що топовим періодом української історії для вітчизняних виробників відеопродукції, що розміщується в українському сегменті YouTube, є період XVII ст. Відповідно топовим історичним героєм – Богдан Хмельницький. Однак для українських користувачів цих YouTube-каналів топовим історичним героєм є Іван Мазепа, символ боротьби за українську, європейську державність. Проведене дослідження демонструє, що упродовж останніх років зріс інтерес українців до історії власної країни. Означена тенденція особливо спостерігається з початком повномасштабної російсько-української війни, яка суттєво вплинула на уявлення людей про власне минуле. А це фактично є початком формування свідомої нації, яка прагне позбутися “зашореності” та імперського минулого, ставить за мету здобути самоповагу і пошану європейської спільноти народів. Це є фундаментом для позбавлення сприйняття українцями себе меншовартісними. одним із важливих кроків до побудови дійсно незалежної держави, рівного партнера на міжнародній арені.

ОСОБЛИВОСТІ ЛІКВІДАЦІЇ ВОЛИНСЬКИХ “ПРОСВІТ” ПОЛЬСЬКОЮ ВЛАДОЮ У МІЖВОЄННИЙ ПЕРІОД
Authors: СТРІЛЬЧУК Людмила , ФІЛІПОВИЧ Мирослава
Published: September 2023

У статті досліджуються особливості ліквідації осередків “Просвіти” у Волинському воєводстві, що її здійснила польська влада у міжвоєнний період. Оскільки “Просвіти” на Волині не мали єдиної централізованої структури, як це було у сусідній Галичині, і діяли за окремими статутними документами, або ж не мали зареєстрованих статутів узагалі, польська влада скористалася цим моментом, аби заборонити діяльність національної організації українців. Враховуючи той факт, що “Просвіти” на Волині існували лише з прикінця Першої світової війни і не зуміли завоювати прихильність більшості волинян, польська влада намагалася перешкодити зростанню численності просвітянських осередків у першій половині 20-х рр. ХХ ст., а з рубежу 20–30-х рр. стала на шлях ліквідації “Просвіт”. І це не випадково, адже національна ідея, яка широко пропагувалася волинськими “Просвітами”, обстоювання Православної церкви, української мови та культури суперечило державницькій доктрині Другої Речі Посполитої: повній асиміляції українців та перетворення Польщі на моноетнічну державу. Метою дослідження є виявлення й аналіз особливостей ліквідації польською владою волинських “Просвіт” у міжвоєнний період, а також простеження еволюції позиції польської влади щодо діяльності та існування “Просвіт” на Волині. Методологічну основу пропонованої статті становлять принципи авторської об’єктивності, історизму, системності та науковості. Широко застосовано також історико-порівняльний та історико-системний методи. Наукова новизна статті опирається на залучення нових архівних документів, що вперше вводяться до наукового обігу, а також на вузькість дослідницького фокусу, адже досі не було опубліковано жодних матеріалів, які б простежували особливості ліквідації “Просвіт” на Волині у міжвоєнний період. Натомість наявні наукові публікації аналізували причини ліквідації “Просвіт” і мали радше описовий характер.
Висновки. У результаті дослідження авторки дійшли висновку, що, враховуючи відсутність у волинських “Просвіт” єдиної об’єднавчої структури, польській державній адміністрації вдалося відносно швидко ліквідувати просвітянські осередки на Волині і замінити їх лояльними владі громадськими організаціями – “Просвітянськими хатами”. Процес ліквідації “Просвіт” розтягнувся у часі на п’ять-сім років, залежно від регіону Волині, ліквідації проходили хаотично, їх тривалість діяльності залежала від позиції керівництва (його здатності до опору). Найбільшою проблемою, з якою зіштовхнулися волинські “Просвіти”, стала передача майна і фінансів.

Published: September 2023

The use of medicinal herbs for the treatment of various diseases of man is dated back to the pre-scientific era. Informed knowledge by the users and various medicinal plant advocates has been the major hitch in the practice and administration of herbal medicine. This work compared the active ingredients in the leaves of two common anti-cancer botanicals (Vachellia tortilis and Bambusa vulgaris) in Ekiti State, Nigeria. The ethnobotanical survey was carried out through visits to medicinal plant users such as native doctors, farmers, herbalists and medicinal plant dealers within the State. 10g of sample of each medicinal plant measured into the amber bottle with the addition of 20 ml methanol was subjected to High-Performance Liquid Chromatography (HPLC), a method used to separate a mixture of complex samples. Results of the phytochemical analysis revealed Tyranton as the highest phytochemical extract cytotoxic effects towards human carcinoma cells. Vachellia tortilis and Bambusa vulgaris extracts are very useful in the utilization of anti-carcinogenic and anti-inflammatory. These can be recommended to medicinal plant users as being effective against the aforementioned ailments.

Published: September 2023

The absence of a competency profile in radio and television systems maintenance is responsible for the NDE Skills Acquisition Centres in Nigeria using a training manual, which contains a few competencies for the training and assessment of students. Therefore, the objective of this study was to develop and validate a competency profile in radio and television systems maintenance for use as a guide in developing a curriculum for the centres. The study adopted educational research and development design employing DACUM model to develop a draft competency profile. The draft profile was produced by 9 technicians and lecturers through task analysis at a 2-day workshop in Kaduna. Thereafter, it was transformed into an 83-item questionnaire which was content validated by three experts and its internal consistency was determined through a pilot test and the data generated were analysed using Cronbach alpha and found to be 0.91. 40 Copies of the questionnaire were distributed to and retrieved from 40 master craft persons teaching at the NDE Skills Acquisition centres in North Central Nigeria. The Data generated were analysed using percentage and factor analysis. The study found out that 6 major tasks and 83 specific competencies were appropriate for use in training and assessment. Based on these findings, it was recommended that the National Directorate of Employment should organise a workshop to develop a competency-based curriculum and assessment instrument to improve the training in radio and television systems maintenance at the centres.

Authors: Gerry Siampondo  , Aggrey Mweemba  , Mbuyu Sumbwanyambe
Published: September 2023

The advent of Corona Virus in 2019 shocked the entire globe. COVID-19 became a worldwide health emergency following its pronunciation by the World Health Organization in February 2020. The spread of the virus across the world led to the consideration of the new norms of life, which included limited physical contact and wearing masks, among other measures. Within a few weeks, COVID-19 changed lives and caused massive human suffering making societal well-being very hard. The novel virus made it difficult for health practitioners to deal with the situation. Beyond the health impacts, the pandemic brought massive issues in jobs, sources of income, and others. In Zambia, the situation was worse in terms of the business environment due to limited access to internet connectivity. Most organizations laid off their workers and forced the remaining personnel to work from home. Additionally, customers also moved back to the use of online platforms. The paper reviews Zambia's work from home experiences and their overall impact on customer experience.
Research on Fund Management of Diversified Tobacco Enterprises
Authors: Yeqing Yuan
Published: September 2023

Although the diversified operation of tobacco enterprises can tap the potential of stock resources, obtain the advantages of scale economy and scope economy, and expand brand influence in breadth and width, on the other hand, a diversified investment may also bring huge risks to tobacco enterprises. This paper studies the non-linear 'U' shaped evolution relationship of tobacco enterprise capital management and comprehensively studies the influence of different property rights, agency costs, financing constraints and other common influencing factors on tobacco enterprise capital management. Moreover, the paper establishes a comprehensive analysis model to test how enterprises effectively use the 'U' shaped evolution relationship with empirical evidence to find the Pareto optimal state among financing constraints, financial flexibility, agency costs and cash holdings.
Talent Management: Its Effect on the Competitive Advantage of Selected Money Deposit Banks in Ogun State, Nigeria
Authors: Dr. Egbuta Olive Ugadiya  , Omoduemuke Naomi Olanike
Published: September 2023

Financial institutions are constantly looking for new competitive advantages due to the intense competition in the banking sector. Financial institutions investing in Talent Management can better weather economic storms and respond to changing customer wants and needs. Furthermore, they have a better chance of attracting and retaining the most talented employees. Deposit-taking institutions have made significant progress in implementing Talent Management strategies. However, the outcome has not been as expected due to high human capital attrition in the banking industry and the fact that the best talents are in high demand and can be expensive to acquire. A survey research design was used for the study. The study included 134 employees from various money deposit banks. The study used a simple random sampling method. For data collection, a well-structured and validated questionnaire was used. The response rate was 69%, and the information gathered was analyzed using descriptive and inferential statistics. According to the findings, Talent Management has a positive and significant effect on the competitive advantage of selected money deposit banks in Ogun State (AdjR2 = 0. 573, F(3, 91) = 39.337, P 0.05). The study recommends that deposit money banks identify, acquire, develop, and retain a competent workforce to improve job performance and competitive advantage.
Coup D’états in the West African Region: A Threat to Regional Human Security
Authors: Thomas Boakye
Published: September 2023

After independence in the 1960s, most West African countries began their state governance with democracies and political liberalization. However, military coups swept across the sub-region in the same period as citizen agitations, and the military's thirst for power called for them. The event of coup since then became contagious as an external factor influencing state domestic politics. In that regard, the occurrence of coups in one West African state influenced the execution of the same in neighbouring states, as the Nigeria-Burkina Faso-Ghana 1966 coups confirm. 

With the phenomenon becoming a political behaviour as people openly called for them in times of economic hardships, coups have become a menace than a panacea to human security in the sub-region. Women and children continue to suffer violations and the constant abuse of their rights. Killings have become rampant and a part of military juntas putting lives in the subregion in fear and jeopardy. With people fleeing military juntas out of fear of being persecuted or in search of political freedom, the issue of refugees has become a constant problem for all states in the region. The paper has clearly captured that the region's human security has constantly been under threat due to military coups d'états, even in the twenty-first century.
Errand War: An Observer’s Perspective on Russian-Ukrainian War
Authors: Dapo Thomas
Published: September 2023

This study traverses a new conceptual direction in war studies. It attempts to establish a simplex in the lexicon of international studies without de-establishing the signification of an extant phrase – proxy war. Errand war is not in competition with proxy war. Errand war, unlike proxy war, is a derivative construct from a leader's message couched and presented with swaggering egotism to the political leadership of an assumed 'subservient' state. Proxy war then remains proxy war. The paper, therefore, introduces with glitz popular elements in warfare and strategic studies such as propaganda psychology, tactical mobilization, collective strategization, intel politicization and multilateral armament syndication. The paper dramatizes the resonant interfaces of the system's actors, starting with the sender to the messenger and the recipients. These trilateral actors, by their adverse actions, are dragging the system to the precipice of war and/or by their propitious traction, they are moving it away from the fringe of war.

Differences in the ways that men and women use language have long been of interest in the study of discourse and sociolinguistics. Despite extensive theorizing, actual empirical investigations have yet to converge on a coherent picture of gender differences in language. The male/female sex biological categories are assumed to have a bearing on the masculine/feminine gender social categories. This categorization is assumed to affect almost every aspect of human living, including the use of language by the different genders. This work is a study of works and assumptions on sex-conditioned language or genderlect, with special attention on the characteristics of female speech. This aspect identified the observed linguistic filtering devices in female speech in an attempt to establish them as stereotypes. The study further attempted a survey of filtered female speech and established pragmatic bases for the models. A clear attempt was made to identify and classify the semantic constraints inherent in the connotative properties of the utterances of some female speakers of the English, Igbo and Yoruba languages while also attempting a possible literal and contextual interpretation of the utterances and the possible 'misunderstandings' that may arise from the 'filtered' utterances. Oral discussions and unobtrusive observations were conducted to get data related to the manifestation of genderlect in female speech. The findings affirmed the thesis of differences in gender speech styles.
Akan Worldview on Human-Earth Relations for Environmental Conservation in Ghana
Authors: Emmanuel Twumasi-Ankrah
Published: September 2023

The idea that there is an interconnectedness between human beings and the natural environment is widely held by many people across the globe. Unfortunately, this nexus has become the cause of the global problem of pandemics, climate change and greenhouse gases. The 2020 Environmental Performance Index (EPI) ranked Ghana low at 39th out of 46 countries in sub-Saharan Africa (SSA). Employing the qualitative method and phenomenological approach, some Akan environmental conservation ideas inherent in human-earth relations were analysed. The paper argues that the Akan indigenous ecological knowledge, such as taboos, observance of earth's Sabbaths, keeping of sacred forest groves and ecological proverbs and wise-sayings are viable resources to be harnessed to theologize in eco-theology and for environmental sustainability.

The health implication of PAHs has been of great concern due to its contamination of the food chain. This study was carried out to identify the health challenges associated with the bioaccumulation of PAHs in Fluted Pumpkin (Telfairia occidentalis) and Waterleaf (Talinum fruticosum) along Imo River Watershed, Imo State, Nigeria. A total of 8 soil samples (0-30cm) were randomly collected from different activity areas on the watershed and analyzed for the presence of the 16 US-EPA priority PAHs in both soil and vegetable samples. The analysis of PAHs in the soil and vegetable samples were carried out in accordance with EPA 8270: (GC-MSD) and the results revealed that amongst the 16 US-EPA priority PAHs, eight of them were detected in the soil and vegetable samples. The total concentration of PAHs detected in the soil and vegetable samples were Naphthalene(0.146mg/kg), Acenaphthylene(0.010mg/kg), Acenaphthene(0.210mg/kg),Phenanthrene(0.021mg/kg),Anthracene(0.041mg/kg),Flouranthene(0.130mg/kg),Pyrene(0.020mg/kg),Benzo(b)fluoranthene(8.641mg/kg) and Naphthalene(0.090mg/kg),Acenaphthene(0.011mg/kg),Fluorene(0.010mg/kg),Phenanthrene(0.230mg/kg),Anthracene(0.190mg/kg),Flouranthene(0.010mg/kg),Benzo(b)fluoranthene(2.711mg/kg),I(1,2,3-cd)PY(0.540mg/kg) respectively. The decreasing order for individual PAHs concentration in the soil and vegetable samples within the study area were Benzo(b)Flouranthene>Acenaphthene>Naphthalene>Fluoranthene>Anthracene> Phenanthrene> Pyrene> Acenaphthelyne and Benzo(b) Flouranthene>I(1,2,3-cd)PY> Phenanthrene> Anthracene> Naphthalene>Acenaphthene> Fluorene>Fluoranthene respectively. For both soil and vegetables, total PAHs concentrations recorded in Obowo zone were observed to be higher than Okigwe zone. The result also revealed high values of PAHs in the edible vegetable samples collected around abattoirs and abandoned waste dump. It is therefore evident from this study that abattoirs and waste dumps have the potential to emit huge amount of PAHs to soil resource, which is taken up by edible vegetables leading to several health challenges when the vegetables are consumed. Different exposure to PAHs results in immune function suppression, cataracts, kidney and liver damage, skin inflammation, asthma, nausea, vomiting, eye irritation, diarrhea, confusion, lung and other cancers and probably death in chronic cases. There is need for public education on the consumption of vegetables grown in and around abattoirs and areas dominated by waste dumps.

Published: September 2023

Many countries are facing internal and external pressures stemming from the surrounding environment, which is represented in a number of economic, political and social changes, especially countries that include ethnic diversity, and their greater responsibility requires them to pay increased attention to their internal structure by placing the management of ethnic diversity and diversity at the top of their agenda. Creating a common identity through which everyone feels a sense of belonging to the state, and the management of ethnic diversity has become an important and often controversial topic in recent times, and the controversy has arisen about cultural pluralism as a systematic and comprehensive response to dealing with ethnic diversity, and in this study we address the phenomenon of pluralism and ethnic diversity in Iran from Non-Muslim religious minorities and how to manage them, answering questions about whether ethnic pluralism can promote internal harmony, equal employment and trust between different minorities and ethnic groups, and a statement of Iran’s policy after 1979 in managing its ethnic diversity in order to clarify the lessons learned from these Experience and its applicability elsewhere, managing ethnic diversity has attracted sociologists interested in race and pluralism Cultural immigration and solutions.

On 15 May 2021, the Tianwen-1 mission delivered a lander and the Zhurong rover to the Mars surface, which made China the second nation to successfully land and place a rover on that planet. The guidance, navigation, and control (GNC) system for the entry, descent, and landing (EDL) of the Tianwen-1 mission play keys role in guaranteeing a successful landing. In this paper, the Tianwen-1 EDL GNC system design is presented, including the GNC architecture, scheme, and algorithm; additionally, the system is validated through experimental tests, numerical simulations, and actual flight results from telemetry data.
Analytical Optimal Solution for the Reachable Domain of Low-Thrust Spacecraft
Authors: Wang Zhaowei , Jiang Fanghua
Published: September 2023

Low-thrust electric propulsion system has drawn increasing attention from researchers because of its high propellant efficiency. The reachable domain of low-thrust spacecraft can provide a geometric insight for space mission planning. In this paper, analytical solutions of the envelope of reachable domain are obtained by employing the Pontryagin’s maximum principle in the well-known linearized model of relative motion, the Tschauner–Hempel equations. Specifically, this study focuses on two contributions. First, an analytical solution of the envelope of reachable domain is obtained, and the associated optimal control profile is derived. Second, an ellipsoid approximation of the reachable domain is proposed to represent the envelope directly based on the analytical solution. Numerical simulations are conducted to demonstrate the accuracy of the proposed solutions. The results show that the reachable domain obtained analytically coincides well with that solved by the numerical indirect method based on the two-body model with low thrust.
Quasi-Two-Dimensional Simulation of a Rotating Detonation Engine Combustor and Injector

Published: September 2023

A numerical simulation of an annular rotating detonation engine with stoichiometric hydrogen–oxygen is performed. A generic, well-posed, and easily implemented approach using a quasi-two-dimensional method to model the area variations through the rotating detonation engine’s injector and combustor is presented. The detonation–injector interaction is studied for the case with a ratio of four between the combustor and injector’s throat areas. A shock wave is formed in the divergent portion of the injector due to the high backpressure created by the detonation in the combustor. A Favre-averaged steady-state analysis of stream lines and particle paths reveals that the shock causes an irrecoverable loss of stagnation pressure. Stagnation pressure gain in the combustor is insufficient to make up for the loss, and the flow leaves the engine with lower stagnation pressure than in the plenum.
Aeroelastic Analysis of Highly Flexible Wings with Linearized Frequency-Domain Aerodynamics

Published: September 2023

Aeroelastic flutter analysis of configurations with geometric structural nonlinearities typically is done with time-domain analysis. The results from this process are computationally expensive and can yield cumbersome results that may be difficult to manage and interpret. Compared to time-domain methods, frequency-domain flutter analysis can provide additional insight into the characteristics of a flutter instability. By linearizing the aeroelastic problem about the nonlinear equilibrium state, this work applies frequency-domain aeroelastic analysis to the Pazy wing, the subject of the Large Deformation Working Group in the Aeroelastic Prediction Workshop. Generalized aerodynamic forces (GAFs) are computed with both a doublet-lattice method and a computational fluid dynamics solver at a range of reduced frequencies as well as a range of dynamic pressures to account for the dependence of the mode shapes on the nonlinear equilibrium state. These GAFs are used in a [Formula: see text] flutter solver, which is modified to handle the nonlinear dependence of the stiffness matrix and GAFs on the dynamic pressure. The hump mode flutter mechanism predicted by the linear doublet-lattice method is found to underpredict the severity of the instability, relative to the computational fluid dynamics-based tool, though the overall static and dynamic aeroelastic mechanisms predicted by the two fidelities are similar.

Published: September 2023

Distributed algorithms are essential for reducing communication costs, computational complexity, and memory requirements while performing collaborative estimation using multi-agent systems. Additionally, robustness in estimators is important to prevent performance degradation when the measurement noise is non-Gaussian. Least absolute deviations estimators are known to be robust in the presence of gross errors or outliers in the measurements. To this end, we develop the distributed least absolute deviations (D-LAD) estimator for linear systems whereby the agents iteratively exchange information with their immediate neighbors via single-hop communications to gain a network-wide consensus on the estimates. Additionally, the D-LAD algorithm is implemented in a nonlinear framework to solve the problem of distributed orbit determination of a target body using a formation of spacecraft. Numerical simulations demonstrating the effectiveness of the D-LAD estimator in linear and nonlinear settings are provided.
