New approaches to casting hypereutectic Al-Si alloys to achieve simultaneous refinement of primary silicon and modification of eutectic silicon
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel UniversityHypereutectic Al-Si alloys are of increasing interest for applications that require a combination of light weight and high wear resistance, such as pistons, liner-less engine blocks and pumps. The wear resistance of this class of alloys is due to the presence of hard primary Si particles formed during casting. The objective of this work was to develop one or more methods of refining primary silicon in cast hypereutectic Al-Si alloys to compete with the conventional process of adding phosphorous and to achieve the simultaneous modification of silicon in the Al-Si eutectic. A robust sampling/casting technique was developed to minimise macro-segregation of primary silicon during solidification of hypereutectic Al-Si alloys by using water cooled steel mould with cooling rate in excess of 15 K/s. The morphology of silicon phases was found to change with increasing melt temperature and cooling rate. The high cooling rate and superheat temperature produces a good distribution of polyhedral primary silicon particles in a refined lamellar eutectic matrix in solidification of commercial purity Al-Si alloys. Removing Ca by fluxing with K2SiF6 prior to casting can improve the refinement and modification effect of Mg and Sb respectively. Effects of various inoculants were studied. Microstructural analysis showed that Mg and ZnS refined primary Si whereas MgO, CaO and Na2S coarsened the primary Si together with a modification effect on the eutectic Si. Adding Zn had no effect on morphology of Si phases. Refinement of both primary and eutectic silicon phases was observed for the Al-15Si alloy with Mg content ≤ 0.3 wt%.
P-doped γ-Al2O3 was found to be a potent substrate to nucleate primary silicon whilst good modification of the eutectic matrix is retained during solidification of hypereutectic Al-Si alloys. On using P-doped γ-Al2O3 could be a perfect and clean source of P without additional impurities.
A new solid-liquid duplex casting process was devised to achieve simultaneous refinement and modification of Si phases in hypereutectic Al-Si alloys with improvement in mechanical properties. The static mechanical properties of Al-Si produced by the solid-liquid duplex casting process are significantly better than conventionally cast untreated Al-Si and slightly better than conventionally cast Al-Si treated with P and/or Sr. A novel Al-ZnS master alloy was developed by in situ reaction of Zn and Na2S in the Al melt. The results from this study leave little doubt that this novel Al-ZnS master alloy is a promising refiner in solidification of hypereutectic Al-Si alloys. It refines primary silicon to the same extent as that achieved by adding P via Cu-P following the same refinement mechanism.EPSRC,U

Musical Instruments in Al-Jahiz
No full textفي كتابات الجاحظ، تناول أديب العرب الجاحظ قضايا الموسيقى والطرب والغناء. كان الجاحظ معروفًا بعلمه وأدبه، وكتب العديد من الأعمال التي تسلط الضوء على جوانب الحياة المترفة في المجتمع. كتب كتابًا بعنوان "أخلاق المغنين" وآخر بعنوان "المغنين والغناء والصنعة". في هذه الكتب، دافع الجاحظ عن الغناء كفن فني، ورأى أنه يمتلك قواعد وأسسًا علمية تشابه مع غيره من الفنون والآداب. كان يروج للغناء باعتباره متعة فنية. وعلى الرغم من انتمائه للمعتزلة، إلا أن الجاحظ كان مشجعًا للغناء ومغنين، وكتب عن أخلاقهم وفنونهم. وفي رسالته "القيان"، تناول الجاحظ تأثير بيوت القيان والقيان نفسهن في المجتمع الإسلامي، حيث أشار إلى الفسق والعشق والفجور الذي قد ينتج عن هذا التأثير. بشكل عام، تركت كتابات الجاحظ أثرًا مهمًا في فهمنا لثقافة الموسيقى والطرب والغناء في العصور القديمة.In his writings, the Arab author Al-Jahiz addressed issues related to music, Tarab (a genre of music), and singing. Al-Jahiz was known for his knowledge and literature, and he wrote numerous works that shed light on the luxurious aspects of society. He authored a book titled "Ethics of Singers" and another titled "Singers, Singing, and the Craft." In these books, Al-Jahiz defended singing as an artistic form and believed that it possessed scientific principles and foundations similar to other arts and literature. He promoted singing as a pleasurable art form. Despite his affiliation with the Mu\u27tazila school of thought, Al-Jahiz was a supporter of singing and singers, and he wrote about their ethics and arts. In his treatise "Al-Qiyan," Al-Jahiz discussed the influence of courtesans and their households on Islamic society, pointing to the immorality, passion, and vice that may result from this influence. Overall, Al-Jahiz\u27s writings have had a significant impact on our understanding of music, Tarab, and singing in ancient times
The Impact of Loan Portfolio Returns on Stock Returns: The Moderating Role of Solvency in Jordanian Commercial Banks
No full textThe current research aims is to test the impact of loan portfolio returns on stock returns in the Jordanian commercial banking sector in the presence of solvency as a conditional variable (moderator). Set in the research represents all Jordan’s local commercial banks listed on the Amman Stock Exchange for the period of 2013–2020. The SPSS program was used to achieve the study’s objective and test its hypotheses. The results showed significant impact of loan portfolio return on stock returns in the Jordanian banking sector. It means that loan portfolio return growth has an impact on shareholder stock returns as it depends on the bank’s financial performance. Solvency is a conditional variable to improve the impact of loan portfolio return on stock returns. Accordingly, the research presents a set of recommendations, Bank managers should focus on loan portfolio management and financial solvency in order to have greater profitability and follow the decisions which are passed by the Basel Committee
Theoretical Insights of History, Morality, and Society as the Literary Trio of the Author-Reader Relationship.
No full textThis paper attempts to examine the relationship between the author and the reader by polarizing history, morality, and society as a selected triad of theoretical interpretation. The study mainly focuses on the theoretical insights of these relationships in order to give proper clues for delving deep into the technical and thematic peculiarities of different literary genres. Therefore, it follows a qualitative approach to some fictional works, particularly novels, to demonstrate how the authorial perspective intersects with the reader’s ability to grasp the latent textual messages projected by authors in the course of the plots. The relationship between the author and the reader will be limited to three related topics, namely, history, morality, and society. As for history, the study sheds light on the postcolonial attributes of literature to reveal the function of liberal humanism in bridging the gap between the colonized people and the colonizers. Morality, on the other hand, will be discussed to explore the relative view of morality by authors and how the reader might conceptualize it according to his/her cultural background. Lastly, the discussion of society will be limited to the social customs and norms approached by authors to deliver a comprehensive depiction of the social reality in which the reader lives his/her true life
Lyman break galaxies and the star formation rate of the Universe at z ~ 6
No full textWe determine the space density of UV-luminous starburst galaxies at z≈ 6 using deep HST ACS SDSS-i′ (F775W) and SDSS-z′ (F850LP) and VLT ISAAC J and Ks band imaging of the Chandra Deep Field South. We find eight galaxies and one star with (i′−z′) > 1.5 to a depth of z′AB= 25.6 (an 8σ detection in each of the 3 available ACS epochs). This corresponds to an unobscured star formation rate of ≈15 h−270 M⊙ yr−1 at z= 5.9, equivalent to L* for the Lyman-break population at z= 3–4 (ΩΛ= 0.7, ΩM= 0.3). We are sensitive to star-forming galaxies at 5.6 ≲z≲ 7.0 with an effective comoving volume of ≈1.8 × 105h−370 Mpc3 after accounting for incompleteness at the higher redshifts due to luminosity bias. This volume should encompass the primeval subgalactic-scale fragments of the progenitors of about a thousand L* galaxies at the current epoch. We determine a volume-averaged global star formation rate of (6.7 ± 2.7) × 10−4h70 M⊙ yr−1 Mpc−3 at z∼ 6 from rest-frame UV selected starbursts at the bright end of the luminosity function: this is a lower limit because of dust obscuration and galaxies below our sensitivity limit. This measurement shows that at z∼ 6 the star formation density at the bright end is a factor of ∼6 times less than that determined by Steidel et al. for a comparable sample of UV-selected galaxies at z= 3–4, and so extends our knowledge of the star formation history of the Universe to earlier times than previous work and into the epoch where reionization may have occurred
