Authors: Moses Wafula Wanyonyi , Wepukhulu Rispah , Opondo Paul A.
Published: April 2023

The period 1964-1988 recorded unprecedented performance of Coffee Sector in Bungoma County as witnessed by the volume of production. For instance, Kenya's coffee production and earnings grew at an annual rate of 6.6 percent per year between 1963 and 1988, with a simultaneous increase in annual yield rate of 0.9 percent. However, after 1988 production declined by 62 percent between 1989 and 2008-10 and by 5.5 percent between 1988/89 and 2009/10. This performance saw various households record favorable returns that had a positive impact on socio-economic development of the study region. The decline in coffee productivity has seen the region fall to a record relatively higher level of poverty index. For instance, Kenya County Facts Sheets (GoK, 2013) gave the poverty Index for Bungoma County as 52.9 percent against the national index of 47.6 percent. This state is a clear pointer that Bungoma County significantly contributes to the national poverty index. It is against this background that this study undertook a historical analysis of the performance of the coffee sector in the period 1963-1988 with the purpose of providing an insight into circumstances that led to the unprecedented performance of the coffee sector in the study period purposed to guide reforms in the coffee sector so that the sector could regain its lost glory. The study was guided by Diffusion of Innovation Theory (DIT). The study adopted a descriptive survey design. The target population consisted of: 7304 coffee farmers spread across, 39 coffee factories in Bungoma County, 39 chairmen of coffee factories as representatives of the management, 6 Agricultural Officers of the Sub-Counties in which the factories are found, and An informed elderly local leader with a wide knowledge of economic activities to offer real testimony on issues that may have been witnessed The study utilized both primary and secondary data. Primary data were collected through interviews and questionnaires. The study established that the high productivity of coffee during the study period was promoted by farmer support programs such as the provision of farm inputs, support education programs, and attractive global coffee prices. The study recommends restoration of the same programs if coffee productivity is to be improved.
A Contextual Analysis of Θεραπεία (Healing) of a Centurion’s Servant In Luke 7:1-10 in Relation to Healing Practices in the Christ Apostolic Church, Ibadan, Nigeria
Authors: Olajide Ademola Julius
Published: April 2023

Healing and health are fundamental to human life. People go to any extent to seek healing. When orthodox medicine fails, people do not hesitate to go to prayer houses and even herbalists to procure healing. The centrality of healing features prominently in Jesus' earthly ministry. In compliance with Jesus' instruction to his followers to preach the gospel and heal the sick, the CAC has made healing one of its major preoccupations. However, there are cases of ministers using extra-Biblical means to perform healing such as the sale of anointing oil, handkerchief, and water. Also, ministers seek gratification from beneficiaries of healing and other abuses that were not witnessed during Jesus' ministry. Therefore, this study investigated healing in Luke's Gospel and its application in Christ Apostolic Church to ascertain the degree of compliance to Jesus' command. The study adopted a mixed method comprising hermeneutical and exegetical methods to analyse the text to bring out the essential meaning of healing in the Bible in relation to the practice of the CAC, and a descriptive method of a survey type was employed. The results of the interview were qualitatively analysed. The study concluded that healing is a fundamental aspect of the liturgy and practice of the CAC, which helps in bringing members to salvation. Therefore, the study recommended that the church's authority should ensure strict compliance with the principles and techniques of healing adopted by Jesus in Luke's Gospel.
Freedom and Agency: Two Critiques to Hard Determinism
Authors: Zhang Shuoning
Published: April 2023

Moral responsibility is the very foundation of all moral actions and social practices. Hard determinism, however, becomes a serious threat to morality by raising the impossibility of moral responsibility. This paper evaluates two criteria under which moral responsibility can be justified, reconstructs Strawson's basic argument of hard determinism, and provides two solutions (one libertarian, one soft deterministic) to the challenge raised by hard determinism. Finally, this paper points out that moral responsibility does not necessarily require freewill as its precondition.
French Language as a Major Factor in the Development of Enugu State of Nigeria

Published: April 2023

The linguistic apparatus of a people is in no small way one of the determinants of what they achieve on developmental issues. This is not only limited to their own local language or dialects but the extent to which they embrace other languages of international standard like French. Enugu state, as the unofficial headquarters of the south-eastern part of Nigeria, has shown an open hand for meaningful investors who sometimes come armed with a wonderful linguistic tool. Thus, the Alliance française of France came at a time when Nigerians were thirty for a new linguistic escapade to embellish the country's land border operations with their neighboring francophone countries; Benin republic, Togo, Cameroun, Ivory Coast, Gabon, etc. Hence the establishment of Alliance française in the country and Enugu state as a French language institute in 1959. In light of the foregoing, the researchers have come up with their biggest question: How has the entrance of French language aided in the development of Enugu State? The responses to the problem would be accompanied by an empirical research that provides, to an extent, the claims of some of the Enugu residents. This question made the researchers observe that since many Enugu residents were of the opinion that studying French has helped in boosting their Academic profiles, overcoming some immigration difficulties, and linking them with the outside world for business purposes, undoubtedly, it becomes clear that the coming of French language in Enugu has done more good than harm because it has helped in human development which according to the research stands out as the best form of development on earth. Finally, the research is an addition to the already researched works on the effects of French language studies on Igbo States, especially Enugu, which serves to a great extent as the epicenter of the Igbo nation.

Authors: Yuniriyanti Eny , Sudarwati Ririn , Susana Erni
Published: April 2023

Gender discrimination in various aspects of social life results in different outcomes between men and women. Differences in treatment, norms, and views that are formed in society between men and women have an impact on various things in life. The younger generation has different desires and expectations from decade to decade because the development of society demands dynamic patterns of thinking and acting. As objects, they still need coaching and development toward growing potential and ability to an optimal level; they are not yet independent.Operational Definition The variable used in this study is students' perceptions of male-female equal partnerships, which means that students' opinions about harmonious conditions between men and women are manifested through the pattern of attitudes and behavior between men and women who care, respect, value and help each other so that between men and women can work together as equal partners by using questionnaires in ordinal measurement data and a Likert scale. The indicators used are a gender analysis framework.For women, there is no difference in perceptions of equal partnerships between 2012 and 2022, which means that women's perceptions are consistent about equal partnerships in terms of a gender analysis framework. Men and women have the same position, rights, obligations, and opportunities to play a role in all aspects of life. In men, there are differences in perceptions of equal partnerships between 2012 and 2022. It means that in terms of the gender analysis framework, men's perceptions of equal partnerships between 2012 and 2022 have experienced positive and significant changes.
Early Children Education through Arts: Pre-school Teachers Views on Types and Frequency of Young Children Engagement in Music Education Activities in Pre-school Settings in Greece
Authors: Nousia Alexandra , Raptis Theocharis
Published: April 2023

The aim of the present study was to examine the frequency of implementing musical activities in the weekly pre-school settings program and the type of musical activities that pre-school teachers choose to implement. Factors that may influence the frequency of implementing musical activities were also investigated. In addition, some indications and changes recommended by pre-school teachers themselves, which would support and facilitate a more frequent implementation of musical activities in the pre-school setting program, were also reported.The Mixed Method Research (MMR) was preferred for this study, which is besides considered a more appropriate method for research in highly multi-factorial areas such as education. The questionnaire was preferred as a basic tool to collect the quantitative data of the study in the quantitative research process. Similarly, qualitative data were explored using the semi-structured interview as the main tool.The study results showed that the majority of the pre-school teachers performed musical activities daily (64.1%). Among the main factors that seem to influence the frequency of music activity involvement, statistically significant differences were only seen between years of service and the age of the pre-school teachers. Some of the pre-school teachers' observations that would benefit from the more frequent implementation of activities from the field of music education were the presence of music educators in the pre-school classrooms, the organization of special training seminars, and providing schools with music education materials suitable for the implementation of relevant activities. Reference was also made to the need to adjust the regulations governing the operation of pre-school settings and the curriculum of the university departments of pre-school education with more music courses.

Published: April 2023

Tomato is a leading crop in the world and in Sudan that is characterized by seasonality and perishability, which causes instability in market supplies and prices in the world, including Khartoum State and other markets of Sudan. This study aimed to estimate market integration in Khartoum State, Sudan. The study depended mainly on secondary data obtained from relevant sources. The study used descriptive analysis, Box-Jenkins Autoregressive Moving Average (ARMA), and Autoregressive Integrated Moving Average (ARIMA) time series analysis. The results of the time series analysis indicated that the prices of tomatoes were stable and variable throughout the year, reflecting a seasonal pattern. The results of the co-integration analysis indicated the strong integration among the different tomato markets in Sudan, with Khartoum and Port Sudan having 85% and Khartoum and Zalingei markets having a 67% level of co-integration. The study concluded that despite the poorly organized marketing system, the tomato market channel is well-integrated as prices tend to move up and down together in all markets of Sudan. The study recommended the encouragement of production and marketing cooperatives for farmers and traders under the close supervision and management of concerned institutions, ministries, and national and commercial banks and the introduction of adequate and appropriate transportation vehicles and packaging material for tomatoes.

Published: April 2023

The BAEC TRIGA research reactor's (BTRR) core lifetime measurement and burn-up calculation were both carried out using the deterministic computation analysis tool TRIGLAV. Since it reached its first criticality in 1986, the BTRR has been used for nuclear research, instruction, training, and the manufacture of radionuclides for around 815 megawatt days without any core reloading or fuel reshuffling. The individual and ring-by-ring fuel burn-up and the core excess reactivity of BTRR have been studied utilizing the TRIGLAV code. The calculated outcomes of the TRIGLAV code and the outcomes of the MVP-BURN code are contrasted. To validate the TRIGLAV code for BTRR core analysis, the initial criticality and operational core analysis metrics like effective multiplication factor and excess reactivity were calculated using the TRIGLAV code. The results from TRIGLAV were compared with experimental data and other codes' output data and showed excellent agreement between them. Actual operational data is contrasted with core excess reactivity data. While the core excess reactivity data will forecast the core life, the collected fuel burn-up information can be used to forecast the core life. The collected fuel burn-up data can be utilized to reload or reorder the fuel. The BTRR may be used safely for an additional 500 MWD by the burn-up and excess reactivity requirements, according to the calculated fuel burn-up, identification of the hottest fuel rod, and excess reactivity value.

Efeito do Roflumilaste sobre a Quimiluminescência do Luminol e a produçao de espécies reativas de oxigênio
Authors: Gileno Miriane Costa , Oliveira Larissa Senna de
Published: April 2023

A Doença pulmonar obstrutiva crônica (DPOC) é caracterizada como uma inflamação crônica do parênquima pulmonar e das vias áreas, responsável por desencadear uma resposta pró-inflamatória que estimula a liberação dos leucócitos e plaquetas. Uma das características importantes dessa síndrome é o aumento na contagem de polimorfonucleares (PMN), que muitas vezes são liberados na sua forma jovem apresentando alto nível de mieloperoxidade (MPO). A identificação destes é essencial para o entendimento das manifestações sistêmicas e das doenças associadas à DPOC. A fosfodiesterase-4 (PDE4) é uma enzima que catalisa o metabolismo dos nucleotídeos, especificamente o c-AMP e c-GMP expresso em inúmeras células e em doenças respiratórias. Alguns inibidores dessa enzima são utilizados no tratamento dessas doenças, destacando o Roflumilaste. O objetivo deste trabalho foi avaliar se o presente medicamento inibe a produção de espécies reativas de oxigênio pelos neutrófilos por método quimiluminescente com o Luminol, pois na inflamação, os agentes oxidantes da MPO são capazes de interferir nas funções das células e contribuir para agressões. Por isso a MPO tem sido utilizada como um biomarcador prognóstico, principalmente nas doenças inflamatórias agudas e crônicas e em doenças pulmonares. Os resultados demonstraram moderadas inibições do fármaco quanto à quimiluminescência dependente do luminol, demonstrando atividade antioxidante.
Percepções dos agentes comunitários de saúde em um município do interior de São Paulo acerca da vigilância sanitária e atenção básica

Published: April 2023

O objetivo deste estudo foi compreender a relação entre a Vigilância Sanitária e a Atenção Primária, especificamente na Estratégia de Saúde da Família, em um município do interior de São Paulo. Buscou-se a percepção, dos Agentes Comunitários de Saúde (ACS), suas ações, as potencialidades e fragilidades relacionadas a essa interação. Trata-se de uma pesquisa de natureza qualitativa, desenvolvida a partir de entrevistas semiestruturadas com Agentes Comunitários de Saúde. Os dados foram tratados com base no conteúdo temático das entrevistas e organizados em categorias: o trabalho do ACS e a integralidade da atenção à saude; a concepção de Vigilância Sanitária; dificuldades e facilidades para o desenvolvimento de ações articuladas. Os resultados demonstraram que as percepções dos ACS, quanto às práticas e ações de Vigilância Sanitária no contexto das suas ações na Estratégia de Saúde da Família, remetem quase que exclusivamente para as questões regulatórias e de fiscalização, em detrimento das ações de promoção e proteção da saúde. Porém, identificou-se que algumas ações de Vigilância Sanitária são realizadas no âmbito da Atenção Primária, porém não são percebidas pelos agentes como tal. Portanto, é fundamental que essa discussão seja oportunizada no âmbito do Sistema Único de Saúde, buscando estratégias para uma maior integração entre a Vigilância Sanitária e a Atenção Básica.

Published: April 2023

A educação não formal ocorre em espaços onde há processos interativos intencionais construídos coletivamente. Os espaços não formais de educação ambiental (EA) são locais onde as pessoas podem vivenciar como o meio ambiente natural é imprescindível para a manutenção das relações ecossistêmicas que garantem a manutenção da vida em todas as suas formas. Assim, o objetivo deste artigo é apresentar um relato de experiência de um programa de EA, elaborado para estudantes do 6º ao 9º ano do ensino fundamental de uma escola pública na cidade de Araraquara. Para os discentes do 6º ano, foi programada uma trilha ecopedagógica da escola à Nascente do Córrego Água Branca, e para os estudantes dos 7º, 8º e 9º anos foram programadas visitas técnicas monitoradas à Estação de Tratamento de Água da Fonte Luminosa, Estação de Tratamento de Esgoto de Araraquara e Estação de Tratamento de Resíduos Sólidos/Cooperativa de Catadores de Materiais Recicláveis Acácia. A seleção desses locais se deu a fim de possibilitar aos estudantes conhecerem, ao longo dos anos finais do ensino fundamental, toda a cadeia do saneamento ambiental de Araraquara. As visitas monitoradas, além de contribuírem para o entendimento dos aspectos técnicos relacionados à cadeia de saneamento, se configuram como uma importante ferramenta de reflexão acerca das relações estabelecidas entre o ser humano e a natureza e entre os próprios seres humanos, reforçando o viés socioambiental da EA. Trabalhos nesse sentido podem contribuir para a construção de programas de EA mais robustos e eficazes, em direção a uma educação transformadora.
Homeopatia para o controle da hiperacidez gástrica: revisão sistemática da literatura
Authors: Chiari-Andréo Bruna Galdorfini , Ventura Renan Françon Araújo
Published: April 2023

Úlcera péptica, refluxo gastroesofágico, úlceras induzidas pela utilização de anti-inflamatórios não-esteroidais, síndrome de Zollinger-Ellison e úlceras decorrentes da infecção por H. pylori são condições em que se verificam distúrbios relacionados à secreção ácida gástrica. Os pacientes relatam dores e desconfortos, além da constatação de danos severos à mucosa gástrica que, portanto, necessitam ser tratados. Os tratamentos baseiam-se principalmente no uso de inibidores das bombas de prótons, que incluem omeprazol e esomeprazol, mas, que apesar da eficácia indiscutível, tem se demonstrado como fármacos causadores de reações adversas severas, principalmente, em condições de uso prolongado. Assim, estes dados apontam para a necessidade de opções terapêuticas eficazes, contudo, seguras, mesmo em condições em que se exige o uso crônico. Neste contexto, este trabalho objetivou apresentar, por meio de revisão sistemática da literatura, recursos homeopáticos que podem ser empregados no controle da hipersecreção gástrica visando, principalmente, a apresentação de uma alternativa terapêutica a pacientes que requerem o uso crônico de medicamentos para esta finalidade. Medicamentos homeopáticos como Nux Vomica, Phosphorus, Kali Bichromicum, Lycopodium Clavatum, Carbo Veg, Hydrastis Canadensis, Graphites e Conium maculatum foram descritos na literatura como eficientes para estas patologias. Entretanto, este trabalho aponta para a necessidade de mais estudos clínicos, permitindo a publicação de artigos originais, que evidenciem a eficácia destes medicamentos, uma vez que, considerando a desordem estudada, a literatura é extremamente escassa e bastante genérica, baseada principalmente em revisões da literatura, pautadas somente na consulta em matérias médicas, que apesar de sua importância, requerem complementação com estudos mais atuais, aumentando a confiabilidade da homeopatia tanto para profissionais da saúde quanto para pacientes.

Merdeka belajar merupakan  kebijakan strategis  dalam rangka mewujudkan transformasi pengelolaan pendidikan di Indonesia yang bertujuan untuk mendorong perbaikan mutu pembelajaran dan hasil belajar peserta didik. Kebijakan Merdeka belajar salah satunya adalah  mengganti pelaksanaan Ujian Nasional menjadi pelaksanaan Asesmen Nasional, yang  disebut sebagai Asesmen Nasional (AN) yang mengukur literasi, numerasi, survey karakter dan lingkungan Pengembangan soal asesmen kelas  berkaitan erat dengan capaian hasil belajar siswa dan penguasaan literasi dan numerasi oleh pemerintah, selain itu Asesmen kelas juga harus merujuk kepada soal-soal Asesmen Nasional yang  menekankan pada penalaran, dengan demikian pengembangan soal Asesmen Kelas  dirasa berat oleh guru-guru, sehingga sangat sedikit guru-guru yang memiliki kesadaran penuh untuk menjadi tim pengembang soal asesmen kelas. Tujuan dari pengabdian masyarakat ini untuk memberikan pengetahuan tentang  prinsip-prinsip penulisan soal penalaran berbasis asesmen nasional untuk  mendukung program merdeka belajar. Metode yang digunakan dalam kegiatan ini; (1) pemberian materi prinsip-prinsip, karakteristik dan indikator (2)  pengembangan instrumen asesmen literasi dan numerasi, (3)  penelaahan soal literasi dan numerasi. Hasil yang dicapai adalah peningkatan pemahaman dan kemampuan guru dalam mengembangkan soal literasi dan numerasi berbasis asesmen nasional yang dapat diterapkan untuk mengukur capaian pembelajaran di kelas.
Similarity and Scaling in a Liquid-Fuel Ramjet Combustor
Authors: Riska Elisabeth , Gany Alon
Published: April 2023

Liquid-fuel ramjets (LFRJs) exhibit high specific impulse (compared to rockets) due to ambient air intake for combustion and rely on storable liquid fuel at controllable mass flow rates. In this investigation, we perform a similarity analysis of an LFRJ combustor in order to determine parameters that can be applied to predict the behavior of an engine of any magnitude on the basis of test results obtained from engines of different scales. Similarity analysis accounting for geometry, transport phenomena, liquid-fuel dynamics, and chemistry is conducted. It defines a series of similarity rules resulting in pressure–diameter scaling. The scaling model was evaluated using Cantera chemical kinetics software and the Hybrid Chemistry Jet Propellant-8 liquid-fuel reaction mechanism, transport properties, and thermodynamic data. It simulates the combustion dynamics as those of a perfectly stirred reactor in order to determine the effects of the pressure and combustor size on combustion efficiency via the degree of reaction completion at various residence times. The simulation confirmed our scaling prediction that, for operating conditions where chemical kinetics are the main factor affecting combustion efficiency, we require pressures that are inversely proportional to the combustor dimensions.
Statistical Approach for Electric Taxiing Requirements for Regional Turboprop Aircraft
Authors: Taltaud Alexandre , Carbonneau-Côté Jérôme , Bouchard Mathieu , Rancourt David
Published: April 2023

Electric motorization of landing gear appears to be one of the alternative solutions to reduce fuel burn, carbon dioxide emissions, and noise during the taxi phase. Because turboprop aircraft operate on short routes, the taxi phase represents an important part of both flight time and fuel consumption. An electric taxiing system (ETS) sized to meet current operational practices could reduce the fuel consumption and remain nearly transparent to the pilots. This paper first presents a statistical approach to define the taxiing requirements for regional turboprop aircraft using 200 taxi phases of 77 aircraft. Requirements of [Formula: see text] maximum acceleration until 15 kt, a 25 kt top speed, and a 13,000 ft distance (including taxi-in and taxi-out) are determined in accordance with the analysis, operational practices, and pilots’ routines. For a speed higher than 15 kt, the acceleration requirement is adjusted using the isopower to limit the mass of the ETS. Then, an ETS with sufficient performance is sized to be integrated in the main landing gear of a regional turboprop aircraft (Dash 8-300). For a standard mission of 270 nautical miles, the expected fuel economy is 3.1% for a payload loss of 2.2% or 1.3 passengers due to the system weight.
Scoring Approach to Assess Maintenance Risk for Aircraft Systems in Conceptual Design

Published: April 2023

Ease of maintenance can significantly contribute to reducing aircraft operational cost. Maintenance risk is defined as the opposite of maintenance ease; it is impacted by many factors, most of which are decided upon during the aircraft’s conceptual design. This paper proposes a novel method to assess the maintainability risks of aircraft systems by combining various aspects on the component level, intercomponent level, bay level, and aircraft level. For each level, all contributing factors to maintenance risk are analyzed and integrated into several scores. These maintenance risk scores can be used to assess the various aspects contributing to maintenance risk, using input parameters available during the conceptual design phase. This paper presents the validation of the scores using different components and aircraft equipment bays, such as avionic racks, the nose cone, and a complex aft equipment bay of a business jet. The proposed maintenance risk scoring method will enhance multidisciplinary tradeoff studies during aircraft conceptual design, considering competing design aspects such as system placement, thermal aspects, impact on aircraft balancing, or even the overall aircraft shape. Therefore, this new conceptual design capability enables designing novel aircraft configurations featuring unconventional system component placement or component bay shapes while considering maintenance aspects upfront.

Published: April 2023

Large-eddy simulations (LESs) are performed for two isolated unheated jet flows corresponding to a Doak Laboratory experiment performed at the University of Southampton. The jet speeds studied correspond to acoustic Mach numbers of 0.6 and 0.8 as well as Reynolds numbers based on the nozzle exit diameter of about one million. The LES method is based on the compact accurately boundary-adjusting high-resolution technique (CABARET) and is implemented on graphics processing units (GPUs) to obtain 1000–1100 convective time units for statistical averaging with reasonable run times. In comparison with the previous jet LES calculations with the GPU CABARET method, the mean-flow velocity and turbulent intensity profiles are matched with the hot-wire measurements just downstream of the nozzle exit. The far-field noise spectra of the Doak jets are evaluated using two methods: the Ffowcs Williams–Hawkings approach and a reduced-order implementation of the Goldstein generalized acoustic analogy. The flow and noise results are compared with hot-wire and acoustic microphone measurements of the Doak Laboratory and critically analyzed in comparison with the NASA small hot jet acoustic rig database.

The energy coupling process indicated by particle density, speed, current density, and power absorption in a thruster using a rotating electric field was simulated using a one dimension, three velocities electrostatic particle-in-cell (PIC) code under different external magnetic field strengths varying from 0 to 80 G. The longer interaction between electrons and the sheath layer due to the increased magnetic field results in a significant decrease in electron speed from [Formula: see text] at 0 G to [Formula: see text] at 80 G; a reduction in electron power absorption from [Formula: see text] at 0 G to [Formula: see text] at 80 G; and an increase in electron density, current density, and total current density about 69.48, 21.11, and 5.4%, respectively. While ions cannot respond to the changes in time because of their large mass. Three types of currents, namely, electron, ion, and displacement, are primarily present throughout the discharge process. Ion current is significantly less than the other two. The characteristics of plasma described exhibit a nonlinear change, dropping at first and then rising when the magnetic field is strengthened. The results have implications for both choosing the magnetic field for the thruster and thoroughly investigating the energy coupling inside the plasma.
Modeling Fiber Microbuckling in the Bending of Soft Composites Using Nonlinear Homogenization

Published: April 2023

A new approach to model the microbuckling of fiber-reinforced soft composites under bending is presented, which takes into account large deformations of the matrix and nonlinear kinematics. It leverages recent advances from the field of nonlinear homogenization of fiber composites to model the response of the matrix under the three-dimensional loading observed during buckling. The model then calculates the strain energy of the system as a function of several parameters, such as the position of the neutral axis or the microbuckling wavelength, whose values are obtained through energy minimization. The moment–curvature relationship predicted by the model agrees with experimental results, particularly in the postbuckling regime. The predictions also capture the buckling wavelength, as well as the fact that microbuckling extends into the tension side for thin laminates, an experimental observation that contradicts kinematic assumptions in previous modeling efforts. A parametric study considering possible variations in the composite laminate shows strong trends for parameters, such as thickness and volume fraction.
Dynamics of a Wavy Axisymmetric Swimmer
Authors: Zhu Qiang
Published: April 2023

A novel underwater locomotion method is proposed. In this method, the propulsion system is designed as an empty tube with two open ends. The sidewall of this tube is deformable so that the diameter of the tube varies both spatially and temporally, following a wavy pattern that travels from head to tail. By using a fluid dynamics model based on the axisymmetric Navier–Stokes equations, we numerically demonstrate that this design is able to generate thrust for self-propelled swimming. The sources of the thrust have been identified. Specifically, the physical mechanisms that assist with the swimming performance are 1) the momentum flux through the front and back openings; and 2) the normal stress at the front and back openings, most notably the suction force at the front opening due to negative pressure there. Moreover, a parametric study has been conducted to investigate the effect of geometric and kinematic parameters upon the performance of the system.
