Jordanian Musiqa Sha’abie: An Expression of Ethnical Authenticity in the Stream of Global Pop Music

This paper aims to establish some theoretical links between ethnical self-identification, popular culture, and the concept of heritage tradition. Live music in contemporary Hashemite Kingdom of Jordan links to and is observed as based on local songs, otherwise known as Sha’abie. Thus, this article will investigate the combination of contextual, traditional, geographic, and religious factors, assisting the cultural comprehension of a Musiqa Sha’abie. It will answer the questions of why and how the musiqa sha’abie finds its principal place within the framework of popular music in Jordan, meanwhile providing new insights into the problem of how music constructs and defines identities. Synchronically, the paper will explain how the Jordanian music has been shifted from its rural roots and thus becoming Westernized, a product of globalization, and an aesthetic reflection of complex manifestation of stereotyped cultural homogeneity. Accordingly, I will trace the impact of the social and historical background of Jordanian culture into its broader context of postmodern music to find legitimacy to the local pop expression, referred to as Sha’abie.Keywords: ethnos, musiqa sha’abie, dabkeh, gina al horani, Jordanian pop music, maqam DOI: 10.7176/JEP/11-23-07Publication date:August 31st 202

Arab Ethno-pop as Seen Through the Prism of the Jordanian Youth: Recreation of Locality, Scattering Globalization, and the Triumph of Amusement

Music preferences amongst young people provide a significant indicator for understanding their ethnic identities. When quantified and studied, the suggested marker could pose to be a substantial asset that establishes a solid understanding of local music and its role as a socio-indicator for aesthetic preference, and resembles an important aspect of cultural, and ethnic self-determination. Grounded in both historical and socio-cultural analysis, this research will study how music, as a medium, shapes and identifies the given nation’s preference in  music. The qualitative aim of the research is to explore the underlying meaning behind popular Arab music. The aim will be accomplished by utilizing a reflective terminological study based on a quantitative analysis (in the form of a questionnaire schemed to cooperative students from the ‘Yarmouk University’ Irbid, Jordan). The data attained from the questionnaire will be employed as a premise for the formulation of the results; and hence, confirming the true importance of contemporary music culture in the development of personal values and musical criteria. Focus is mainly pivoted on modern Arab pop music being interpreted as ‘ethno-pop’, and interactions found between Western pop and Arabic music will be discussed thoroughly. This conjunction will be looked at as in fact being an exchange of experiences and symbolic norms.

Micro-channel air cooled condenser performance with two-phase flow of zeotropic refrigerant at high ambient temperatures

A study of the thermal performance of an air-cooled micro-channel condenser using zeotropic refrigerant blend R-410A operating at high reduced pressure and at hot climate was conducted. The investigation of the condensation process at high ambient temperature is worth considering because the condensation saturation temperature should be high enough to be cooled by air at high ambient temperature. In this case a high operating pressure corresponding to the high condensation temperature is required; therefore, the condensation process of R-410A occurs at near-critical pressure and the vapour compression cycle operates in hot weather. In order to achieve a successful condensation process operating at hot climate, micro-channel tubes were suitable because of the high heat transfer coefficient associated with tubes of very small hydraulic diameter. The local heat transfer coefficient of R-410A was determined experimentally during the condensation process across the vapour-liquid dome at 0.7 and 0.8 reduced pressures and at 35 and 45℃ ambient air temperatures, in two different rectangular tubes of Dₕ* =1.26 and 0.52 mm, over a mass flux range of 200≤G*≤800 kg/ m²s. Although, the temperature glide of the refrigerant R-410A was sufficiently small, the measurement of the mass flux and the heat transfer during condensation with other measuring parameters were always difficult to achieve with a high level of accuracy. The latest technology of the micro-foil heat flux sensor technique was used with a bespoke facility to accurately determine the heat duty of condensation along the micro-channel tubes. The behaviour of the heat transfer coefficient with the vapour quality was addressed. In addition, the behaviour of heat flux, vapour quality and wall temperature with the thermal length of the channel were intensively studied. The heat transfer coefficient was found to increase with the mass flux and the vapour quality and to decrease with the ambient temperature. Correlations by other researchers mostly disagreed with the present experimental data. Annular flow regime was adopted due to the cross section of tubes at these diameters. A new correlation in annular flow regime that accounted for the effect of near critical pressure of such refrigerant and the high temperature of the coolant air in the geometry of tubes under consideration was proposed to predict the heat transfer coefficient of condensation for which the available models are insubstantial. The resulting correlation successfully computed the experimental data. The physical comprehension and correlation resulting from this research contribute to enhance the existing knowledge for designing and optimising new equipment that utilise R-410A for air-conditioning and refrigeration applications, particularly in hot climates

Utilizing Available Residual Pressure in Fujairah Lines in Bypassing Al Ain Reception Station Considering Transients and Water Hammer Conditions

The objective of this study is to utilize the available residual pressure at Fujairah Transmission lines in order to save energy, operation and maintenance costs, and still deliver the required water to the end users of the distribution network. This has been achieved by bypassing the existing pumping stations (i.e. AARS Reservoir and pumping stations in addition to the local reservoirs and pumping stations of each area). The possibility of transients, surge, and cavitation occurrence was studied via a comprehensive transient simulation to make sure that the proposed bypassing will not have any impact on the upstream transmission system by any operating conditions of the distribution system. A number of water demand scenarios in each zone of the city, in which the available energy is usually wasted under the current operating conditions, were studied in the proposed bypass. Suitable solutions were proposed such as Pressure Relieve Valves and Air Valves to eliminate or at least to minimize unacceptable performances. In addition, the remaining residual pressure in the line was ensured to be sufficient to deliver water to the end users in the studied areas. Finally, the annual savings including energy operation and maintenance costs was estimated to be AED 4.06 Million (about 1.11 USD) while the capital cost of the proposed bypass was estimated to be AED 6.6 Million (1.81 USD). Such saving is associated with about 1 year and 8 month\u27s payback period. This study will help in reducing the cost of potable water delivery to end consumers in Al Ain region by reducing operation costs, maintenance costs, spare parts, manpower, etc ... through utilizing available residual pressure in the transmission lines. In addition, this study will save power consumption that can be utilized in other fields or alternatively reduce power generation. This may have a positive impact on our environment by reducing the amount of CO2 generated during power production. Existing pumps that will be decommissioned can be utilized elsewhere and thus saves the cost of purchasing new pumps. Finally, this study will improve the potable water quality by reducing or even eliminating the stagnant time of water in the storage tanks. This is in line with the current national efforts trying to achieve full integration of the transmission with the downstream distribution systems

ASSESSMENT OF OIL QUANTIFICATION METHODS IN SOYBEAN AND CHIA SEEDS AND CHARACTERIZATION OF OIL AND PROTEIN IN MUTANT CHIA (\u3cem\u3eSALVIA HISPANICA\u3c/em\u3e L.) SEEDS

This thesis includes two main parts: I. Evaluation of techniques for oil (total lipid) quantification of chia and soybean seeds. This study evaluated ten different methods of seed oil quantification, including some methods that have not been applied to oilseeds before. The main aim of this study was to find one or more techniques that are easy, inexpensive, safe and fast with a small amount of ground seeds. The Soxhlet method was used as a standard to compared between techniques of oil quantification. The oil extraction by the Soxhlet method was evaluated with two solvents petroleum ether and acetone. There is not a statistically significant difference between petroleum ether and acetone solvents. No significant differences for the amount of oil recovered via the Soxhlet method were found between Medium Moisture Content (MMC \u3e 10%) and Low Moisture Content (LMC \u3c 4.0 %). The Folch technique provided higher percentages of oil extraction than Bligh and Dyer and hexane-isopropanol techniques. There is not a statistically significant difference (P =0.0844) between Soxhlet method and Folch method but less than the Soxhlet method. A supercritical fluid extraction (HCH) method provided a lower yield of oil extraction compared with the Soxhlet method for three varieties of bias samples. A Direct Transesterification (DT) method with LMC and MMC provided a statistically significant difference than the Soxhlet method. The DT with LMC produced higher yield than DT with MMC between samples but lower than the Soxhlet method. A Double Direct Transesterification (DDT) following Griffiths protocol provided more accurate results with the stir bar technique than sonication technique. 11 oilseeds bias samples (10 bias samples of soybean and one of chia) covering an oil content range of 15.4 to 32.6% showed, there is a significant difference between the Soxhlet and DDTG method and high oil quantification found with DDTG. A Double Direct Transesterification following Qiao et al. (2015) provided similar oil extraction to the Griffiths et al. (2010) method and also there is a significant difference between the Soxhlet and DDTQ method and higher oil recovered with DDTQ. The Bead Beating Extraction (BBE) protocol showed, there is a statistically significant difference ( P\u3c 0.001) than the Soxhlet method. The BBE provided high oil quantification comparing with the Soxhlet method. The BBE provided the best results since it is the easiest, cheapest and fastest oil quantification method. A Nile red fluorescence technique yield no clear results. II. Characterization of oil and protein in mutant chia (Salvia hispanica L.) seeds. The objectives of this study were to (1) measure heritability in chia plants of levels of oil and protein content and seed yield and (2) Compare differences between two locations over two years for oil and protein percentages in chia and seeds yield. A population of 180 M3 mutant individual chia plants was harvested and for which forty M4 chia seeds were planted based on seed composition characteristics, with six plants representing each characteristic (high and lower oil, protein, and density and high yield). The forty M4 chia seeds were planted, with two replications for two locations, have been chosen in Kentucky one on Spindletop farm and the other in Quicksand farm. The M5 progeny seeds from plants grown in Spindletop and Quicksand contained significantly (P \u3c 0.05) more protein than did seeds from the M4 parents. There were significant differences (P \u3c 0.05) between locations where Quicksand obtain higher oil content than Spindletop. There was no significant difference between M5 parents seeds and M4 progeny seeds and higher yield kg/ha at Quicksand than Spindletop

Inflectional Deviation of Gender in the Qur’an

Inflection, part of morphology, has its own rules that govern the combinations of morphemes in words and the relationships between parts of speech within a text. Yet, inflection including that of gender can vary across different linguistic systems. Arabic and English notably contrast in gender-based relations. More specifically and within Arabic itself, the Qur’an displays striking cases of gender disagreement between grammatical categories within a text. Such deviating forms, as using a masculine verb with a feminine subject, a masculine subject with a feminine predicate or a masculine adjective to modify a feminine noun, are very unlikely to appear in other Arabic text genres. These are utilized in the divine text as rhetorical devices to create certain effects or achieve a linguistic power on the audience, in addition to other functions. This special use of gender deviation and the functions it purports to perform in the source text are likely to be lost in translation. Of course, this is attributed to the fact that the target language system neither accommodates the same inflectional rules governing gender relations in Arabic, on the one hand, nor can it provide equal deviating or gender-based disagreements, on the other
