This paper examines the intricate task of translating the Divine Names attributed to Allah's act of creation within the Holy Qur'an. The study focuses on six specific Divine names, exploring their meanings and interpretations in Arabic, and scrutinising their translations in three wellknown English translations of the Qur'an by Yusuf Ali, Pickthall and Sahih International. The analysis reveals that while these names may appear synonymous, they actually denote distinct aspects of the Divine Act of Creation. The paper highlights the challenges translators face in faithfully conveying the profound depth and richness of these Divine names' meanings, given their unique attributes. The study underscores the complexity inherent in accurately conveying the comprehensive meaning of the Divine Names of Allah in Translation, emphasising the indispensable role of supplementary elucidatory mechanisms in bridging the gap between the Divine Names and their adaptations in translations.

In this study, we synthesized the visible-light-driven photocatalytic activity of CdO nanowires and g-C3N4/CdO hybrid nanostructure by the hydrothermal method. X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectrometry, and UV–Vis diffuse reflectance spectroscopy studies were carried out to compare the structural, morphological, and optical properties of CdO nanowires and g-C3N4/CdO hybrid nanostructure. Also, we investigated how CdO nanowires and g-C3N4/CdO hybrid nanostructure function as photocatalysts in the photocatalytic oxidation of RhB under visible light illumination, which revealed that g-C3N4/CdO hybrid nanostructure exhibits better photocatalytic oxidation on RhB than CdO nanowires with the first-order degradation kinetics. The prepared g-C3N4/CdO hybrid nanostructure can provide hybridized conduction band or valence band, which facilitates better charge transport and reduces recombination electron-hole charge carriers leading to higher photocatalytic performance. Hence, making hybrid nanostructures such as g-C3N4/CdO can be a potential approach to develop effective photocatalysts for treating effluents discharged from textile and dyeing industries.

The effect of g-C3N4 on the structural, optical, and photocatalytic properties of ZnO microcrystals under hydrothermal conditions was investigated in this research. The addition of g-C3N4 changed not only the phase composition, but also affect the growth of ZnO crystals, changing the lattice parameter and the transformation of hexagonal cylinder-like twinned ZnO microcrystals (1–2 μm length and 0.5–1 μm diameter) to g-C3N4 amalgamated rice-like ZnO nanostructure (500 nm length and 100 diameter) with type II heterojunction. The optical bandgap was found to be 3.27 and 3.21 eV for pristine ZnO and g-C3N4@ZnO, respectively. Owing to the narrow bandgap (2.7 eV) of g-C3N4, a red shift towards the visible region in optical absorption and a substantial reduction in the optical bandgap was observed for g-C3N4@ZnO heterostructure. Besides, it is also found that g-C3N4@ZnO has significantly higher photocatalytic effect (93 %) on RhB dye degradation than pristine ZnO (70 %) and g-C3N4 (68 %), because it produce a large number of reactive species (·OH and O2•− radicals) by hold-up the recombination of charge carriers via type II heterojunction. This research may be one of the most realistic approaches to developing effective photocatalysts for environmental remediation. [ABSTRACT FROM AUTHOR]

In this paper, grey relational analysis combined with Taguchi method has been used to evaluate the weld ability of AZ31B magnesium alloy by FSW process. The L9 Taguchi design considering an orthogonal array consists of 3 factors and 3 levels was used for experimentation. The rotational speed of tool, transverse speed and angle of tilt of the tool are selected as welding parameters. The welding parameters influence on responses namely Ultimate Tensile Strength (UTS) and hardness has been analyzed using ANOVA. The analysis results showed transverse speed as the predominant welding parameter affecting tensile strength, hardness, and weld quality. Confirmation test results showed that grey relational analysis along with Taguchi method yielded better results in the optimization of welding parameters in FSW of AZ31B magnesium alloy.

Dye‐sensitized solar cells (DSSCs) have considerable attention to the academic and industrial community. Because, it makes solar energy efficient and cost effective to harness. DSSCs is one of the important roles in the design of sensitizers with sustainable and environmentally‐friendly materials. In the present work, a series of D‐π‐A architecture with tetrahydroquinoline based organic dye sensitizer were designed and modifying π‐linker (SP1‐SP9) for the potential use in DSSCs application by DFT and TD‐DFT calculations. There are different functional groups were analyzed through a proper methodology for calculations and comparison with C1‐1 dye. From these functionals, the TD‐ωB97XD method was reasonably capable of predicting the absorption spectra of the molecules. Moreover, SP1‐SP9 dye molecules were systematically analyzed by using various parameters such as the energy gap (Eg), absorption spectra, light harvesting efficiency (LHE), open circuit photovoltage (eVOC), dipole moment (μnormal), free energy change for electron injection (ΔGinject), regeneration (ΔGreg) and chemical hardness (η). As a whole, all the designed dyes, especially SP6, SP7, SP8 dyes are showed smallerEg , red‐shift absorption spectra, largest μnormal , negative ΔGinject and fastest ΔGreg values, compared to C1‐1. Based on our result shows that SP6, SP7 and SP8 dye molecules are the best candidates to provide superior performances in the DSSCs application. [ABSTRACT FROM AUTHOR]

There have always been debates on how to teach, what to teach and when to teach what. Over time, teaching methods have frequently been revisited and updated. Recently, with the advent of computer technology, there emerged some new teaching methodologies like corpus-based learning (also called Data-Driven Learning (DDL)) and computer-assisted language learning (CALL). This means that the practices and the attitudes towards English teaching need to be updated, too. This is not, however, the case in English classes in MENA countries where teachers predominantly use the traditional methods of teaching. Consequently, recent reports have shown that MENA countries have the very lowest proficiency in English language in the world. This paper introduces corpus linguistics and corpus-based learning to the MENA English classrooms in order to improve the English language learning process and make, for the time being, a balance between traditional and modern teaching methods. This balance can be realized in incorporating inductive learning with ductive learning one the one hand, and student-centered classes and teacher-centered classes on the other. In order to showcase the advantages of using corpus-based method in the language classroom, corpus-based materials and concordances are designed using the Sketch Engine and the Brown corpus.

A facile approach for the synthesis of La2CuO4, CeO2, La2CuO4/CeO2 and novel La2CuO4/CeO2/rGO hybrid nanocomposites were demonstrated via solvothermal assisted homogeneous precipitation method. The surface morphology, phase and crystal structure of the synthesized materials were characterized by field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX), High resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD). The photocatalytic performance to oxidize a target pollutant RB160 dye and inactivation of bacteria in aqueous solution was investigated under the illumination of visible light. Absorption range and band gap energy were investigated by UV-vis diffuse reflectance spectroscopy (UV-vis DRS). The combination of rGO with La2CuO4/CeO2 nanocomposites leads to a better photocatalytic activity than other bare synthesized materials. Typically, 10 mg/l of RB160 could be almost completely oxidized in 150 min and 0.01 g/l of La2CuO4/CeO2/rGO, exhibiting a promising application of the photocatalyst in the degradation of aqueous organic pollutants. The efficiency of RB160 decomposition increased with increasing pH (5-11) and catalyst dosage (0.01-0.03 g/l), but it gets decreased with increasing initial RB160 concentration (10-30 mg/l) and from that the optimum condition for the better photocatalytic performance was identified. Furthermore, the antibacterial activity of La2CuO4/CeO2/rGO hybrid nanocomposite was also investigated by using two different bacteria in typical aqueous medium and the results were showed highly efficient visible light driven photocatalytic antibacterial activity. The enhanced photocatalytic and antibacterial activity of La2CuO4/CeO2/rGO is promising for the further application of visible light driven photocatalyst in polluted water treatment.

Geometry of tool pin profiles plays a significant role in deciding the quality of weld in friction stir welding process. In the present study, the effect of tool pin profile on the mechanical and metallographic characteristics of the friction stir welding on AA 5052- H32 aluminium plates was investigated. Various geometry of tool pin profile such as cylindrical tapered, hexagon tapered, pentagon tapered, square tapered, and, triangular tapered, having a constant circumscribed circle diameter were used for the study and the results are compared. Other weld parameters such as tool tilt angle, rotational speed, welding speed were kept constant based on the response from several trial runs conducted. Mechanical test results reveal that highest tensile strength and hardness value were obtained with tapered square tool pin profile and the joint failed under ductile mode. Fine equiaxed grain structure was observed at the stir zone with tapered square tool pin profile. EDS result on plate welded by tapered square tool pin profile shows that there is no β-phase (Mg2Al3) precipitate at the stir zone and therefore no sensitization of segregation as the result of FSW, thereby resists localized intergranular corrosion at the weld site.

A series of Pb doped CeO2 nanocubes with seven different Pb loadings (2–12 mol%) were synthesized via modified hydrothermal technique. The prepared samples were characterized by XRD, XPS, FT-IR, TGA, SEM, HR-TEM, EDS and UV–Vis DRS analysis. According to XRD analysis, the crystalline structure of synthesized pure CeO2 and Pb-doped CeO2 samples are cubic structure. The ceria nanocubes showed an increase in amount of oxygen vacancies with increasing the dopant concentrations. When the doping level of Pb is 6 mol%, the optical band gap of Pb-CeO2 is smaller than that of pure CeO2 nanocubes. The HR-TEM results confirms the cubic structure of 6% Pb-CeO2 with average crystallite size of about 15 nm. The photocatalytic ability of Pb-CeO2 catalysts were studied by degrading several anionic and cationic organic pollutants like methylene blue (MB), methylene orange (MO), methylene red (MR), rhodamine B (RhB), reactive blue 160 (RB160), salicylic acid (SA), coumarin and phenol. The 6% Pb-CeO2 nanocubes shows better photocatalytic performance against anionic dyes especially for MB. To find the optimum condition for better photocatalytic performance of 6% Pb-CeO2 nanocubes, the photocatalytic process was conducted in different initial reaction conditions like reaction temperature, catalytic dosage, dye concentration and pH of the reaction solution. The stability and recyclability of 6% Pb-CeO2 photocatalyst was studied by XRD, FT-IR and EDS analysis after 5 cycles of MB degradation. The hydroxyl radical estimation and trapping experiments were conducted to observe the photocatalytic mechanism process in 6% Pb-CeO2 nanocubes. The perfect doping concentration for better organic pollutant degradation by Pb-CeO2 is found to be 6 mol% of Pb.

The development and study of Na ion batteries are expanding. This study employs the hydrothermal technique to produce single-phase, well-crystallized, fluorine-added O3-type NaFe1-xMgxO2. Using XRD, FESEM, and HRTEM, the sample’s phase structure and morphological information were characterized. Initially, without adding fluorine the electrode suffers from poor stability at high voltage ranges and also during long-term cycling. So, fluorine was added to the structure and the electrochemical performance of the material was greatly increased. The electrochemical performance of O3-type positive electrode materials for rechargeable Na ion batteries is evaluated. The capacity of fluorine-added O3-type NaFe1-xMgxO2 is approximately 163 mAh g−1 (50 mA g−1). Adding fluorine to the host structure increases the stability of the electrode, leading to improved electrochemical performance during long-term cycling. The electrochemical results indicate that fluorine-added O3-type NaFe1-xMgxO2 cathode material for cost-effective and environmentally friendly sodium-ion batteries is promising. Fluorine-based electrodes will be a future for Na ion energy storage devices

The effect of succinylation rheological and thermal properties of cassava starch was studied. Succinylation is considered as an ideal modification since it provides derivatives with desirable properties and unlike many other derivatives; it is approved as safe additive up to 5%. Succinylation of tuber starches showed detectable variations in the various physicochemical. thermal and rheological properties of native starches. Onset temperature increased from 63.13 to 67.14. and the gelatinization enthalpy reduced from 14.69 to 13.57. Rheological evaluations revealed that as the shear rate increases, the viscosity reduces, that is 71.4 lo 1.29 Pa. The dynamic oscillatory measurement showed that magnitudes of G' and G" increased with increase in frequency with the high frequency dependency, suggesting a solid elastic-like behavior.

Abstract: The base of this paper is to find the pressure distribution over the compressor blades through a cascade, which is useful to measure the flow properties of the compressor in an actual axial compressor. The static pressure distribution is obtained from the static pressure holes around the central blade which equipped with the manometers. Plot the graph between the pressure distribution and the spacing between the leading edge to the static holes. And we have to predict the Mach number doing the same procedure to get the results. After that experimental result, we have to analyze the whole experimental cascade series of blade by using software. A result from the software is compared with the experimental measurements. We have to predict the Mach number and change the pitch of the blades and the blade angle do the same procedure as mentioned before and take different plots to analyze in which parameters the compressor blades are got the optimum pressure rise.

The uses of sweet potato tubers rely on the physicochemical and functional properties of its starch. The different properties studied from 14 lines include cooking quality, extractable starch, dry matter, starch, sugar, carotenoids, and anthocyanin. The properties of extracted starch like swelling volume, solubility, amylose content, clarity of paste, rheological properties were examined. The organic matter content of different lines almost remained the same. Starch content of the tubers was greater than 20% and the sugar content ranged from 1-3%. The extractable starch was in the range of 16-21%. The anthocyanin content was high for ST- 13, while ST- 14 was rich in carotene. The swelling volume was comparatively low and the solubility ranged from 8.81-13.65%. Most of the starches examined in this present study displayed excellent viscosity properties with peak viscosity greater than 3000 cP. This study revealed that many lines have excellent potential for use as nutritive and calorific food and as industrial raw material. [ABSTRACT FROM AUTHOR]

In the present work, multi-objective optimization of the input welding parameters influencing the quality of weld joint of AA 5052 H32 aluminium alloy by FSW process is investigated using response surface methodology and grey relational analysis. The quality of the welded joint is measured based on the higher value of tensile strength and hardness of the joint obtained by experimentation.
