High order approximation scheme for a fractional order coupled system describing the dynamics of rotating two-component Bose-Einstein condensates
No full textA coupled system of fractional order Gross-Pitaevskii equations is under consideration in which the time-fractional derivative is given in Caputo sense and the spatial fractional order derivative is of Riesz type. This kind of model may shed light on some time-evolution properties of the rotating two-component Bose¢ Einstein condensates. An unconditional convergent high-order scheme is proposed based on L2-1σ finite difference approximation in the time direction and Galerkin Legendre spectral approximation in the space direction. This combined scheme is designed in an easy algorithmic style. Based on ideas of discrete fractional Grönwall inequalities, we can prove the convergence theory of the scheme. Accordingly, a second order of convergence and a spectral convergence order in time and space, respectively, without any constraints on temporal meshes and the specified degree of Legendre polynomials N. Some numerical experiments are proposed to support the theoretical results. © 2023 the Author(s).King Saud University, KSUM. A. Zaky and A.

Numerical Study on the Occurrence and Sensitivity of a High-Frequency Instability in an Advanced Can-Annular Combustion System
No full textGas turbines for power generation use lean premixed flames to adhere to the strict pollutant emissions regulations. Unfortunately, this often leads to thermoacoustic instabilities. These instabilities can lead to failure of system components, flame blow-off or flashback and a reduction in efficiency. Especially the high frequency transverse thermoacoustic instabilities can lead to big problems in the successful operation of gas turbines. These instabilities can be reduced by adding damping devices or mitigating the excitation mechanisms. In this work, Large Eddy Simulation (LES) is used to identify the thermoacoustic instability which tends to occur in a specific heavy duty gas turbine combustor design. In order to successfully counteract this instability, identification of the acoustic mode affecting the burner is required. Results from the LES are compared with experiments to test the predictability of LES and research mitigation techniques. The oscillation amplitudes do not match due to numerical damping, but the frequency of the oscillation in LES is within 1% of the experimental value. Furthermore, a coherence between the heat release and pressure oscillations of 80% is achieved and the phase of the oscillations are within 90° of each other. This confirms that the Rayleigh criteria is satisfied and the instability in the simulation is indeed a self-excited thermoacoustic instability. After identifying the mode, Fast Fourier Transform (FFT) of the pressure data at the combustor walls is used to visualize and locate the mode. Its location suggests that fuel supply oscillations could be a possible driving mechanism. However, the frequency of the oscillations in the fuel supply did not match that of the thermoacoustic instability so this hypothesis was rejected. After identifying the mode, the effect of different simulation and operation parameters is researched. First a model coefficient which influences the flame length is changed. Shortening the flame results in a higher amplitude instability, due to the location of maximum heat release moving closer to the location of the source of the instability. Next, the fuel distribution is changed in order to break flame symmetry and reduce the instability amplitude. This is done successfully, as the amplitude of the instability at the peak frequency is reduced to the same level as the surrounding noise frequencies. Finally, the effect of adding Helmholtz resonators specifically designed for the instability of interest is researched. A transfer function is defined to measure the response of the resonators to a pressure fluctuation in front of them. The result is compared to an analytical solution to determine the effectiveness of the resonators. Like the fuel biasing, also the resonators performed well and resulted in a decrease of the instability amplitude
Kajian Balaghah Dalam Al-Qur’an Surat Luqman
No full textThe science of Balaghah is in fact not only examined by text. Long before that, it turns out that in the Qur'an there are the beauty of languages that the Arab poet could not have matched though. More interesting, the beauty and style of language in the surah Luqman when studied with the science of Balaghah contains three important elements in human life. Namely, the education of Aqidah, sharia and morality. In this study Balaghah science is examined specifically and in depth by the author with ilmu Ma'ani. In the science of Ma'ani, the authors deepen the study of Insha Kalam discussing Amr Balaghi. And at the end of this study the author found 2 out of 9 kinds of Balaghi Amr, both of which have the meaning of al-Irsyad and at-Tahdid. Amr has the meaning of al-Irsyad found in verses 12, 14, 15, 17, 19, 21. While Amr has the meaning of at-Tahdid in verses 7 and 33. And all the meanings of al-Irsyad and at-Tahdid this can assert the meaning of the content of the surah Luqman itself. So in the end, it can help in human life. At the same time, it confirms that the Qur'an is a miracle for human understand

ABSTRACT
The semiotic method used in the analysis of a poem shows the existence of a communication process between the author and the reader. In this analysis, poetry is seen as a complex communication system in which authors convey their meaning using the right choice of words, orderly sentences and in the form of perfect verses. The analysis using this method aims to find out and process the hidden meaning that the author wants to convey so that there is no misunderstanding of the reader. This research uses the poem "Nahrul Ahzan" by Nizar Qabbani as a research forum. The purpose of this study is to find out and identify the existence of communication between authors and readers through the analysis of heuristic and hermeneutic readings. This type of research is qualitative and descriptive research with a semiotic approach to poetry. This research is also supported by journals and previous research that discusses semiotics. The data collection method in this study is reading and recording techniques. Meanwhile, the data analysis method in this study goes through several stages, namely data reduction, data presentation, and conclusion drawn. The results of the research obtained through heuristic and hermeneutic methods are as follows: the poem Nahrul Ahzan by Nizar Qabbani describes the condition of the author and his grieving lover about separation. The main cause of the sadness of the two lies in the author who has committed bad deeds and is forced to slowly distance himself from his lover

Face processing in autism spectrum disorder
No full textBackgroundAutism spectrum disorder (ASD) is a lifelong neurodevelopmental disorder that is characterized by impaired social and communicative abilities as well as restricted, repetitive, stereotyped pattern of behaviors, interests, and activities. Significant difficulties in social interactions in autistics are manifested by impairment in eye-to-eye contact, social reciprocity, and response to emotional cues.ObjectiveHighlighting the neurological basis of normal face processing and its abnormalities in ASD with percussions on the management plan of autistic children.SummaryHuman face processing that was proved to be compromised in autistic individuals is pivotal for proper social interactions. Such simple spontaneous perceptual task in normal children is carried out by face processing areas of the brain; fusiform gyrus, superior temporal sulcus, and amygdala. Behavioral, electrophysiological, and neuroimaging studies showed evidences of dysfunction of such areas in autistics who often focus on face periphery and cannot interpret that it tells something about a person's state of mind. Very early targeted intervention can stimulate face processing areas of the brain during the early developmental phases of social brain circuitry which in turn will help autistics to pay attention to faces and learn to understand emotional expressions.ConclusionEventually, prevention or at least significant amelioration of severity and symptomatology spectrum of autism might be possible.Disclosure of interestThe author have not supplied his declaration of competing interest.</jats:sec

Studies on the production, chemical composition and nutritional value of mushroom
No full textChemical and biological assays were performed with freeze-dried samples of the cultivated mushroom Agaricus brunnescens. Dried fruitbodies were subjected to proximate analysis, and protein, carbohydrates, fat, moisture, ash, and amino acid contents were determined. Diets containing 10% mushroom protein resulted in PER of 1.5 and NPR of 0.74 compared with values for casein of 2.7 and 2.4, respectively. No significant differences were observed between the weights of the pancreas, spleen and livers of the mushroom protein-fed rats and casein-fed rats. The mushroom fruitbodies were found to contain 10.7% dry matter and the chemical composition of 39.5% protein, 2.0% fat, 39.2% carbohydrates and 9.5% ash. Furthermore, the amino acid analysis showed that mushrooms contain all the essential amino acids and has a protein score of 51.2. In addition, mushroom was found to be nutrient dense in protein, iron, magnesium, phosphorus, thiamin, riboflavin, niacin, and vitamin C.Dried blood and soybean meal were added separately to the mushroom compost at spawning at the rates of 0, 2.5, 5.0 and 10.0 percent of the dried compost spawned. The effect of supplementation on yield, chemical composition and amino acid content of the mushroom produced were studied. Supplementation with dried blood resulted in 28.1% to 56.3% increase in yield obtained as a result of different levels of application. The addition of dried blood at 10% level increased the amount of threonine, tyrosine, phenylalanine, tryptophan, proline and serine with a 19.4% increase in the sulfur-containing amino acids. Supplementation with soybean meal resulted in an increase of lysine, phenylalanine, alanine, arginine, glutamic acid, histidine, proline and serine. Further supplementation with 5% dried blood resulted in yield increase of 25% at first break (crop), 29.3% at second break and 22.1% at third break. Dry matter and protein content increased in the first and second breaks then started to decrease in the third break.Made available in DSpace on 2011-05-07T13:12:15Z (GMT). No. of bitstreams: 2

KEPUTUSAN MUKTAMAR NAHDLATUL ULAMA TAHUN 1989 TENTANG VASEKTOMI PERSPEKTIF METODE INSTINBAT HUKUM ISLAM
No full textAbstract: This study focuses to answer two main problems. First, how is the decision of NU’s (the renaissance of the Muslim scholars) congress in 1989 about vasectomy? Second, how is the methodological analysis of the legal reasoning against the decision of NU’s congress in 1989 about vasectomy? This is a qualitative-bibliographical research on the decision of NU’s congress in 1989. Then, the source is compiled with descriptive analysis. In this case, the author understands a legal adjustment of vasectomy case from the sociological and medical development today according to the decision of the Nahdlatul Ulama’s Conference in 1989. First we need to understand the decision of the Nahdlatul Ulama’s Conference which states that regulating the scarcity of the number of mortality through any means can not be allowed if it reaches a limit to switch off the absolute thoroughbred function. Therefore, sterilization might be allowed is the one which can be restored the ability to reproduce and not to damage or remove parts of the functioning body. The second is the distinction of medicines that prevent permanently and those that prevent temporarily. If the medicine can prevent pregnancy permanently, it is absolutely forbidden. In making decision, NU tends to use the qauly method. It is taking textually from the book to determine the validity of vasectomy.Abstrak: Penelitian ini bertujuan untuk menjawab permasalahan Rumusan masalah yang akan dijawab dalam penelitian ini adalah: 1) Bagaimana keputusan hasil muktamar Nahdlatul Ulama tahun 1989 tentang vasektomi? 2) Bagaimana analisis metode instinbat hukum terhadap keputusan muktamar Nahdlatul Ulama 1989 tentang vasektomi? Penelitian ini merupakan penelitian kualitatif dengan teknik analisis berupa kajian kepustakaan (library research) dari sumber buku yaitu hasil keputusan Muktamar Nahdatul Ulama tahun 1989. Kemudian sumber tersebut disusun dengan deskriptis analisis untuk menemukan hasil sebuah analisis baru dari penjelasan sumber yang ada. Dalam kasus ini penulis memahami adanya penyesuaian hukum tentang kasus vasektomi dari sisi sosiologis dan perkembangan medis di zaman sekarang menurut keputusan Muktamar Nahdlatul Ulama pada tahun 1989. Pertama perlu kita pahami mengenai keputusan Muktamar Nahdlatul Ulama yang menyatakan bahwa mengatur kelangkaan jumlah kelahiran melalui cara apapun tidak dapat diperkenankan jika mencapai batas mematikan fungsi berketurunan secara mutlak. Karenanya, sterilisasi yang dapat diperkenankan hanyalah yang bersifat dapat dipulihkan kembali kemampuan berketurunan dan tidak sampai merusak atau menghilangkan bagian tubuh yang berfungsi. Kedua pembedaan obat seperti obat yang mencegah secara total dan obat yang mencegah sementara waktu, haram apabila obat yang mencegah secara total tidak akan kembali hamil, mubah hukumnya sama dengan ‘azl (apabila mengeluarkan sperma diluar vagina). Dalam pengambilan keputusan tersebut, Nahdlatul Ulama menggunakan metode qauly yakni mengambil hukum secara langsung dari kitab, untuk menentukan keabsahan tindakan vasektomi
