تجليات الإيقاع في قصيدة)) في ما مضى كنت بالإعياد مسروراً)) للمعتمد بن عبّاد الإشبيلي
Authors: القوسي شفيق علي صالح
Published: January 2023

الملخص

مما لاشك فيه أن الموسيقى تمثل روح الشعر وجوهره بل هي إحدى المقومات الأساسية التي يعبر من خلالها الشعراء عن أفكارهم ومشاعرهم وخلجات نفوسهم. ولا نبالغ إذا قلنا إن الموسيقى في الشعر هي سبب من الأسباب الرئيسة في المحافظة عليه ووصوله إلينا، فكم من قصيدة خلدت وذاع صيتها، بسبب جمال موسيقاها وروعة مقاطعها، وهذا ما وجدناه في قصيدة المعتمد بن عباد الإشبيلي (فيما مضى) حيث بث الشاعر شجونه المحزنة، وسكب خواطره الحزينة. وأظهر مدى حزنه وتفجعه، وخاصة بعد ظهور بناته بتلك الصورة التي تبعث الحزن والكآبة، ويتفطر القلب حزنا وحسرة.

وخلصت الدراسة إلى أن المعتمد استخدم موسيقى الشعر ووظفها توظيفا دلاليا ونفسيا من خلال التكرار والجناس والموازنة ومن خلال الوزن والقافية أيضا. ليثمر ذلك التوظيف في إثراء الجانب لإيقاعي في القصيدة بما يحقق الشعرية، ويشد انتباه القارئ للتفاعل مع الشاعر والتماهي مع شعوره الحزين.

 

ABSTRACT

There is no doubt that music represents the spirit and essence of poetry, but rather it is one of the basic ingredients through which poets express their thoughts, feelings and souls. We do not exaggerate if we say that music in poetry is one of the main reasons for preserving it and reaching it to us. And he poured out his sad thoughts. He showed the extent of his sadness and grief, especially after the appearance of his daughters in this image that sends sadness and melancholy, and the heart breaks with sadness and heartbreak.

The study concluded that the author used poetry music and employed it semantic and psychologically through repetition, alliteration and balancing.

And by weight and rhyme too. This employment results in enriching the rhythmic aspect of the poem in a way that achieves poeticity, and draws the reader’s attention to interacting with the poet and identifying with his sad feeling.

The influence of Poisson's ratio in the calculus of functionally graded plates
Authors:   Military Technical Academy, Bd. George Coșbuc, 39-49, S. 5, Bucharest, 050141, Romania, NĂSTĂSESCU VASILE
Published: January 2023

A current problem, of increased difficulty, which is still under continuous development, is the calculus of functionally graded plates (FGPs). Functionally graded materials (FGMs) represent a special category of composite materials, usually made on the basis of two materials, with very different properties, so they vary continuously between the extreme surfaces of the material, where the properties are those of the respective materials in their pure state. Today, the most used materials used in the construction of FGMs are ceramic materials and metals. Their volume fractions, in the thickness direction, varies continuously, according to a material law, valid for all material properties. A problem, generally poorly substantiated, is the one related to the assumption of a constant value of the Poisson's ratio over the entire plate thickness of the functionally graded plates. This hypothesis admits an analytical solution, by direct integration, of the stiffness of the plate, but it certainly does not reflect reality. There are some ways of approaching the calculation of functionally graded plates, such as the multilayer plate concept or the equivalent plate concept, which can take into account the variation of the Poisson's ratio on the plate thickness. The paper highlights this aspect and, in addition, evaluates the influence of the variation of Poisson's ratio on the calculation of displacements, stresses and natural vibrations of functionally graded plates. The work represents both an original way of approaching the calculation of functionally graded plates and a quantitative substantiation of the hypothesis of a Poisson coefficient with a constant value.

Research in the present paper has highlighted the availability of using bronze coatings, obtained by electric arc spray (EAS) method, for the purpose of increasing the life time of materials tested for abrasive sliding wear. The experimental plan of the work includes the analysis of three types of samples: S1 (samples deposited with a CuAl 90-10 layer on a steel-type base material), S2 (casted sample from CuAl9 material) and S3 (bearing material sample). The sliding wear analysis were obtained on a specific testing machine in a lubricated environment (clean oil) at a preset loading, obtaining both the friction coefficient for each material type and the material loss for each sample. The results showed an average strength of the bronze coated sample (S1), its mechanical characteristics being higher to the other two analyzed samples.
Thermal rehabilitation of residential buildings or efficiency vs effectiveness in envelope of existing buildings
Authors:   ", DABIJA ANA-MARIA ,   Academy of Technical Sciences of Romania, Department of Construction and Urbanism, Bucharest, Romania Renewable Energy Commission of the Romanian Academy, Bucharest, Romania"
Published: January 2023

"Starting from the definition of the terms, efficiency generally refers to the management of resources in order to achieve a goal, while effectiveness represents the ability / effective quantification of the achievement of a goal. In other words, efficiency is a process while effectiveness is an outcome. Having said that, the question rises (rhetorical, after all): was the process of thermal rehabilitation of the residential building stock efficient? Was it effective? Efficient it probably was: with the resources at the disposal of the town halls, with funds attracted and with the contribution of owners' associations (when the situation demanded their participation), a huge number of residential buildings were covered in thermal-insulating blankets. Was the expected result achieved? In other words, was it effective? The question may have many answers, considering the angles, the nuances and perspectives from where the intervention is evaluated, from the very basis of the approach – the hypothesis and the concept - to the architecture of the buildings and their relationship with the urban space of which they are a part. The paper proposes a critical analysis of the results of the approach to the thermal “wrapping” of residential buildings in Romania as well as in the European research and practice."

The purpose of this research is to design an automatic leak detection and fire extinguishing system called FEARLESS. The method used is a case study methodology and applied. From the data obtained in the field, it was found that there were 4 gas detector disturbances in 2019 and 5 times in 2020 which resulted in no detection of gas leaks when the detector was disturbed, as well as 34 gas leaks in 2019 and 42 times in 2020. From this data, it is used as a reference in designing the FEARLESS (FIRE SUPRESSION AND SMART ALERT SYSTEM) to detect gas leaks. The application of the FEARLESS system can be drawn several conclusions, including applying the FEARLESS system can reduce the failure or damage that occurs so as to minimize the occurrence of undetected gas leaks. The FEARLESS system can be combined with two or more detectors to be implemented for various needs.

Se presentan en este texto introductorio las clases prácticas de la asignatura sociología del conocimiento llevadas a cabo por Pablo Infiesta Molleda durante el curso 2009‐2010 como un modelo para vincular investigación, enseñanza y capacidad crítica.
Introducción
Authors: Infiesta Molleda Pablo
Published: January 2023

En el presente trabajo se estudia la génesis del Proyecto Genoma Humano (PGH) desde un enfoque filosófico. A la vista de la cuantiosa bibliografía sobre el tema, quizá las siguientes páginas pudieran parecer impertinentes, pero no pretendemos elaborar una mera paráfrasis, más o menos afortunada, de varios ensayos previos porque este trabajo supone una reacción crítica frente a esos mismos ensayos. Nuestro proceder es, desde un primer momento, dialéctico, pues supone una rectificación de las distintas exposiciones acerca de la génesis del PGH. Por ello, hemos de tomarlas en consideración como contenidos del propio trabajo. El análisis pormenorizado sería excesivo; una breve reseña, casi a título inventarial, de los ejemplares más destacados permitirá ejemplificar los problemas mencionados, además de ofrecer un primer bosquejo de los contenidos y contornos de la investigación.
La constitución de la biología molecular como ciencia
Authors: Infiesta Molleda Pablo
Published: January 2023

La dimensión científica del Proyecto Genoma Humano (PGH) remite a un conjunto de entidades de orden biológico: bases nitrogenadas, genes, enzimas, SNP’s1, etc., sobre las cuales se ejercitan las operaciones tecnológicas que dan lugar a la secuenciación del genoma. Un examen más atento muestra que todos los cuerpos, morfologías y estructuras que forman parte constituyente del PGH pueden circunscribirse al campo de la biología molecular, con lo cual están dados a la misma escala, lógicamente. Esta primera suposición, que habrá que constatar en la reconstrucción ulterior, permite regresar hacia el curso de la constitución de la biología molecular, como factor del contexto histórico determinante del PGH, sin tener que retrotraerse a procesos anteriores de la historia de la biología para dar razón de la conformación y conexión de los trazos que forman parte de la figura de referencia.
desarrollo de la biotecnología
Authors: Infiesta Molleda Pablo
Published: January 2023

La realización del Proyecto Genoma Humano (PGH) supuso la utilización de diversas técnicas de cartografiado y secuenciación del genoma. En términos muy generales, los mapas del genoma permiten identificar y aislar genes individuales, esto es, fragmentos de ADN que codifican una determinada cadena polipeptídica. Por su parte, la secuenciación consiste en la determinación del orden de las bases nitrogenadas del ADN. Las técnicas implicadas en ambos procesos, aunque plurales y heterogéneas, tienen su origen en el ámbito de la biotecnología. En su desarrollo constatamos cómo un conjunto de realidades heterogéneas se configuran como artefactos, operadores y relatores, en relación a otras configuraciones circulares y radiales con las que se codeterminan.
biología molecular: ¿revolución o cierre?
Authors: Hidalgo Tuñón Alberto
Published: January 2023

El surgimiento de la biología molecular en la frontera que separa la teoría genética y la bioquímica constituye un buen banco de pruebas para distintas estrategias metacientíficas. El teoreticismo de las revoluciones científicas de Thomas S. Kuhn propende hacia un constructivismo social que no sirve para dar cuenta de la posible verdad y corrección del teorema de la doble hélice. El enfoque semántico (desarrollado por J. Sneed, W. Stegmüller, U Moulines, etc.), aunque pretende adecuar sus análisis a los contenidos estructurales y al significado de los teoremas científicos, acaba disolviendo estos en meras correspondencias formales. La teoría del cierre categorial, en cambio, se adscribe a un constructivismo circularista que permite entender los dogmas sobre la estructura del ADN como si fueran identidades sintéticas materiales sin desdeñar por ello los aspectos pragmáticos, históricos y sociales, que valoran en su justa medida las aportaciones del grupo Fago, de Watson y Crick, de Pauling o de las universidades implicadas.

Published: January 2023

Background: Three-thirds of people with radiologically isolated syndrome (RIS) develop multiple sclerosis (MS) within five years following their first brain magnetic resonance imaging (MRI). Subclinical applications of optical coherence tomography (OCT) include measuring the thickness of different retinal layers and monitoring the progression of visual pathway atrophy and neurodegeneration in relation to the progress of the entire brain. Objectives: Our OCT study was conducted in individuals with RIS to evaluate the thickness of the macular retinal nerve fiber layer (mRNFL) and the retinal ganglion cell layer (RGCL). Methods: In this study, 22 patients with RIS and 23 healthy individuals healthy control (HC) were enrolled. The control group and the RIS subjects underwent retinal imaging with OCT. Results: Total mRNFL thickness was 110.34 ± 13.71 μm in the RIS patients and 112.10 ± 11.23 μm in the HC group. Regional analysis of the mRNFL showed that the difference in thickness was more prominent in the superior quadrant. In regards to ganglion cell layer (GCL)++ thickness, the RIS and HCs population showed statistically significant differences in the nasal (P = 0.041), inferior (P = 0.040), and superior (P = 0.045) quadrants. The nasal (P = 0.041) quadrant showed the highest reduction in thickness compared to other regions of the GCL++. Meanwhile, no significant reduction was seen in GCL+ thickness (P-value > 0.05). When the thickness of the retinal layer of the right eye was compared to that of the left eye of the RIS group, no statistically significant differences were found (P-value > 0.05). Conclusions: Compared to the control group, the RIS group had a lower mean thickness of mRNFL and GCL++, indicating retinal neuroaxonal loss.
Emotionally Loaded Visual Stimuli to Alter Brain Arousal: A Flicker Fusion Study
Authors: Ghanbari Zahra , Choobineh Alireza , Zakerian Seyed Abolfazl , Gharagozlou Faramarz , Nami Mohammad
Published: January 2023

Background: Human brain performance and arousal are still challenging and critical, especially in environments such as power plants. Since different emotions are common in daily work life and have inevitable effects on cognitive performance, it is important to evaluate whether emotional interventions can alter brain arousal. Poor cognitive performance in control room operators (CROs) can lead to mental fatigue and affect their cognitive emotion regulation. To address this issue, flicker fusion frequency (FFF) was employed as a simple and reproducible surrogate index for mental fatigue. Objectives: This study aimed to investigate whether emotionally loaded visual stimuli can alter brain arousal (brain fatigue) or is associated with cognitive emotion regulation (CER) ability. Methods: Flicker fusion frequency was assessed by RT-961, and the International Affective Picture System (IAPS) was adopted as the picture database of stimuli. Additionally, the Cognitive Emotion Regulation Questionnaire (CERQ) was used to determine the participants’ cognitive emotion CER ability. Twenty volunteer CROs from Fars Combined Cycle Power Plant participated in this study. After completing the CERQ, they were assessed at 2 different time points (ie, before and after presenting emotional stimuli). Flicker fusion frequency was assessed 20 times at each round, and the average frequency was recorded. Emotionally loaded images were considered as stimuli. The stimuli sets were classified based on their arousal levels and valences, yet they were presented in random order. Subjects were exposed to each image for 5 seconds (30 minutes in total). Results: The participants’ mean age was 39.55 ± 7.02 years. The first and second FFFs were 42.15 ± 3.90 and 41.96 ± 3.98 in the appropriate group and 42.82 ± 3.59 and 42.26 ± 4.07 in the inappropriate group. Based on the statistical tests, there were no significant relationships between the measurements (P > 0.05). Conclusions: Control room operators may positively maintain their brain arousal during specific emotional stimuli when the intervention lasts less than 30 minutes. Considering the prolonged working hours in such industries (roughly over 8 hours a day) and the importance of cognitive aptitude in preventing work-related errors, we propose this line of research to gain momentum.
The Impact of Modified Team-Based Learning on the Learning of Students in an Orthopaedic Course
Authors: Husein Khalid Elfadil , Mahmoud Elsiddig Elhadi
Published: January 2023

Background: This paper presents the results of a modified team-based learning (MTBL) in the Orthopaedic Department of the Omdurman Islamic University. It is a modification of the team-based learning (TBL) developed by Dr. Larry K. Michaelson, who explored the benefit of small group learning within large classes. TBL differs from other forms of small group work, which involves developing and using learning teams in large settings as an instructional strategy. Objectives: The main difference between conventional TBL and MTBL is that students learn in small groups in a single large class with a single facilitator in conventional TBL. In contrast, in MTBL, students learn in separate small classes with different facilitators. In this study, we investigated the impact of MTBL on the learning of students in an orthopaedic course. Students’ satisfaction and grades, following the MTBL for an orthopaedic class, were analyzed and compared to another batch of students in a conventional lecture learning strategy. The two batches were taught by the same faculty members. Methods: The MTBL was implemented as a teaching method in orthopaedics and traumatology course in 2020. A total of 282 students were surveyed for their satisfaction with this new pedagogical approach, and 153 students responded to the questionnaire. We adopted a self-administered questionnaire answering on a five-option Likert scale. The five options represented the levels of agreement. At the end of the course, students’ exam scores were compared to the results of their previous batch, in which teaching was carried out utilizing conventional lectures only (a total of 128 students). Results: The results showed that the majority of the students involved in the study (66.5%) were satisfied with the MTBL. The students thought that it increases the long retention of knowledge and should be used more frequently in the curriculum, and they recommend it to other students. The analysis of the examination results using the Chi-square test revealed a significant difference between the results of the students who studied the course in the form of MTBL and those who studied the course in the form of a traditional lecture with a clear improvement in the results following MTBL orthopaedic course (P-value = 0.0000). Conclusions: We, therefore, conclude that the MTBL where students are divided into separate small groups with different instructors improves the performance and the grades of the students in the exam. It also reveals that the students feel satisfied with the learning technique. We recommend it be more frequently used in the curriculum.

Reliability Evaluation of Transformer Oil Insulation with H2O Water and Super O2 Water Contaminants Disaster Mitigation Electrical Engineering
Authors: R Christiono , Garniwa Iwa , Fikri Miftahul , Amar Thahara Andi
Published: January 2023

Transformer oil insulation failure is one of them that can cause water to penetrate through the mechanical acrylic cap on the OLTC (on load tap changer) which causes contaminants in the transformer insulation oil which affects the reliability of the transformer until there is damage to the transformers widely. For this reason, research was carried out to evaluate the reliability of transformer oil insulation with contaminants of H2O water and Super O2 water. This study is to evaluate the effect of water contaminants with experimental methods using BAUR Oil Tester test equipment, with H2O water and super O2 as samples of water contaminants on transformer oil insulation. According to SPLN 49-1: 1982, the standard value of breakdown voltage in insulating oil is ≥30kV/2.5mm. Then, 1ml of H2O water will be given so that a decrease in the breakdown voltage value of 31.5% is obtained and this experiment is carried out up to 10ml, which means that the more H2O is given, the value of the breakdown voltage is further away from the SPLN standard. Meanwhile, insulating oil contaminated with super O2 water obtained a breakdown voltage of 68% which means that the more super O2 water, the more the reliability of transformer oil insulation decreases, and the breakdown voltage value also decreases which adversely affects the reliability of the transformer.
Attitude Estimation of Four-Rotor UAV Based on Extended Kalman Filter
Authors: Miao Hui Wang , Thompson Michael
Published: January 2023

Quadrotor unmanned aerial vehicle (UAV) is a typical multi-input multi-output (MIMO), nonlinear and strong coupling underactuated system. In the working process of the system, it is necessary to perform information fusion on the attitude detected by the sensor to achieve accurate measurement of attitude angle and angular velocity. Accurate and efficient measurement of UAV attitude angle is the basis of UAV flight control. In this paper, the extended Kalman filter (EKF) algorithm is used to estimate the attitude information of the four-rotor UAV. Firstly, a four-rotor UAV simulation model is established on Simulink in Matlab, and then the attitude information of the UAV is measured and estimated. The results show that the extended Kalman filter algorithm can effectively estimate the attitude information of UAV.

Published: January 2023

With the deepening of research on unmanned vehicles, research on USV (Unmanned Surface Vehicle) has gradually become extensive. In order to cope with complex Marine operations, the study of USV cluster collaborative operations has been emphasized. Therefore, this paper explores USV cluster formation and collaborative obstacle avoidance. In this paper, a formation control method of USV cluster is proposed based on the leader-follower architecture and the consistency algorithm. To solve the problem of formation cooperative obstacle avoidance, the traditional APF (APF method) is improved to avoid falling into the local optimal, and the cluster cooperative obstacle avoidance method is proposed. Finally, the simulation results show that the USV cluster formation control and obstacle avoidance methods are effective.
The Feasibility of Trajectory Controller by SS Equation of an Error Model in WMR
Authors: Qev Yang , Meshach Mesho
Published: January 2023

There has been an increasing amount of research on WMRs. The WMRs have lots of advantages: their mechanical system is usually simple; the whole movement mostly contains two dependent motors; and their motions in two-dimensional space are quite adaptable. At the same time, the WMRs have better power efficiency. WMRs have been studied from many points of view, such as modelling control, obstacle avoidance, localization, tip-over stability, and so on. This paper discusses the control algorithm. WMRs have nonholonomic constraints. That is, the mobile robot may not be able to reach a specific position and angle in a specific time; however, the robot can reach the target in a different motion or within a limited time. In this paper, an error model based on the WMR is introduced. The model explains the error between the actual position and the ideal or target position in the continuous motion of WMRs. The error model will be transformed into a state-space equation in order to demonstrate that the algorithm that controls the WMR`s movement is controllable. By splitting the inputs  into  and , the whole equation is transformed into a zero-input state-space system. Then, the errors can be minimized with the optimization of the feedback. The results show that by optimizing the time-varying feedback matrix, the error is asymptotically stable and close to zero. Therefore, by adding this control law to the controller, an approach to making mobile robots follow the planned trajectory is obtained.
The Influence of Ethnic Identity on the Academic Performance of Chinese College Students: An Empirical Study Based on the Administrative Data of a University
Authors: Wang Zerong
Published: January 2023

The policy of ethnic equality and solidarity aims to narrow the ethnic gap and develop harmoniously. At the level of higher education, it should promote the equity of ethnic education. This paper uses the administrative data of undergraduate students from 2008 to 2015 in a liberal arts university in southwest China to study the differences, causes and dynamic trends in the scores of college students from different nationalities. The results show that compared with Han students, the average GPA of ethnic minority students is 0.13 points lower (equivalent to 0.23 and 0.3 standard deviations of the scores of ethnic minority and Han students), the fourth grade scores are 0.28 standard deviations lower, and 7.3% lower. This difference is more significant in the western region, especially in Xinjiang, Yunnan, Hubei and other provinces inhabited by ethnic minorities; Kazak and uygur are the nationalities with the biggest gap with han students; The difference between girls is more significant than that between boys. The "peer effect" and cultural distance between roommates are important reasons for this difference. Further analysis shows that although the ethnic differences in academic performance are gradually expanding, the growth rate tends to converge. The above conclusions are helpful to clarify the object and time of making national higher education policy, and also have important reference significance for primary and secondary education.

Published: January 2023

Scientific and technological innovation and human capital savings are important ways to promote the high-quality development of China's economy. On this basis, using the panel data of 30 provinces in China from 2009 to 2017, this paper empathically tests the impact of university research activities on high-quality growth of China's economy, and explores the influence mechanism from two dimensions of talent cultivation and achievement transformation. Based on the spatial perspective, the regional heterogeneity of these influences is analyzed. This paper finds that: First, research and development activities in universities effectively boost the high-quality development of China's economy. Secend, the stimulating effect of university research and development on economic growth. On the one hand, through the talent training function of scientific research activities, it enriches the accumulation of human capital and drives the economic development; On the other hand, constrained by the predicament of scientific research achievement transformation, the stimulating effect of university scientific research activities on economic growth will be limited to a certain extent. Third, there are significant regional differences in the promoting effect of university research activities on high-quality economic development, and this difference may come from the spatial spillover effect of university research activities. This study has important enlightening significance to understand the relationship between university scientific research activities and high- quality economic development.
Research on the Impact of Digital Finance on China's Urban-Rural Income Gap
Authors: Zhang Zhe
Published: January 2023

The integration of digital technology and traditional finance has further achieved the goal of low-cost and sustainable financial services and contributed to high-quality economic development. Based on the data from 31 provinces in China from 2011 to 2021, this paper empirically analyzes the impact of digital finance on the urban-rural income gap. The results show that digital finance can significantly narrow the income gap between urban and rural residents. The quantile test shows that the greater the urban-rural income gap, the stronger the role of digital finance in narrowing the urban-rural income gap. The threshold effect test shows that the narrowing effect of digital finance on the urban-rural income gap will first increase and then weaken with the continuous improvement of the development level. Heterogeneity analysis shows that the secondary indicators of digital finance can significantly narrow the urban-rural income gap, and the effect of depth of usage is the most obvious. Moreover, digital finance has a significantly stronger effect on narrowing the urban-rural income gap in the eastern region than in other regions. Therefore, we should vigorously promote the development of digital finance and give full play to its effectiveness in narrowing the urban-rural income gap.

Lack of questions and answers and group discussions built by the teacher in conducting learning in the classroom so that students are less effective and students cannot learn actively. The ability and responsibility of teachers in choosing learning methods or models that are suitable and in accordance with teaching material in a learning process determine the continuity of learning, teachers still use conventional learning models that make students passive in class. Therefore, students' communication skills are very low which causes student learning outcomes to be based on an average. Thus the cooperative learning model Talking Chips type is needed which applies to be adapted to teaching materials in order to improve students' abilities in communication, and can improve student learning outcomes

Human being is the best creature of Almighty Allah. It was felt that an accurate celestial book was needed to win the satisfaction of Allah while maintaining his superiority. It is a great mercy of Almighty Allah that He revealed the Quran as a book to solve all problems. The first instruction of this book is ‘Read’. But He did not make it clear about the method of reading. Based on the instruction of Allah, the Holy Prophet PBUH prepared a group of world-renowned enlightened people by focusing the light of education to the human being through various methods. Subsequently, to make that education easily available to the people, according to the demand of time, various educational methods were developed in different times. One of these methods is formal education and the other is open and distance learning with a combination of formal and non-formal education. Bangladesh Open University is offering education through this method of education in the country. The main point of this article is to discuss this method in the light of the Holy Quran and the Hadith. However, before onsetting the main discussion, the purpose of establishing Bangladesh Open University, its education system, and open and distance learning methods, its aims and objectives and characteristics have briefly been discussed.
