The impact of asset management on achieving bank profitability (Applied study within Al-Khaleej commercial bank)

Banking activity is essential in countries' economies, as banks are considered intermediate financial institutions between surplus and deficit. Bank managers work on achieving the main objectives of any bank, which are: (profitability, liquidity, and security) by balancing the management of assets and liabilities and avoiding risks that face their work, such as liquidity risks and credit risks, as asset management is concerned with choosing the optimal investment combination for available sources of funds, as the funds are utilized in a variety of ways to reduce risks and obtain profit. Maximizing the bank's profitability is the responsibility of the management, as maximizing profitability is a strategic goal for the bank, and it will contribute to expanding the bank's work and obtaining a larger market share. The research was based on the analysis of banking profitability indicators (income of assets, income of investment) and their impact on profitability. As asset management is the one factor that affects the returns of assets and acquisitions, and, in turn, bank profitability is concerned. Thus, asset management must invest money elaborately and keep risks at bay

Multiplicity in Parsing: Concept and Reasons

التعدّد مفردة يراد بها في المعجمات العربية الكثرة, والإحصاء, وتتعلق الدراسة بالكثرة الواردة في الوجوه النحوية للمفردة, ولا تعلق لها بالمعنى الآخر (الإحصاء)؛ لأنّنا نبحث في كثرة الوجوه النحوية في إعراب المفردة.   والمراد بالتعدّد: هو كثرة التوجيه النحوي في إعراب المفردة. و(الإعراب): تغيير يحصل في آخر الكلمة فينقلها بين الحالات الإعرابية التي تحتملها كالرفع, والنصب, والجر, والجزم, حسب ما قعّده النحاة, وحصل التعدّد الإعرابي نتيجة أسباب متعددة كان لها أثر بارز في احتمالية المفردة لأكثر من وجه نحوي, فمنها ما يتعلق بالتقديم والتأخير, وتعدّد معنى التركيب, ومنها يتعلق بوظائف الكلمة, والوقف والابتداء. وقد انتظم هذا البحث في مبحثين، تكفل الأول بيان مفهوم التعدد الإعرابي، بينما كان الثاني معقودًا لبيان الأسباب التي تؤدي إلى التعدد الإعرابيّ، ويعقب هذين المبحثين خاتمة تضمنت أهم نتائجه، وقائمة بالمصادر والمراجع التي استقى منها مادته.Multiplicity in Arabic dictionaries is a term that is intended to mean richness and identification. This study relates to the richness of the grammatical cases of the word and it is not related to identification, because we are after the large number of grammatical cases in the parsing of a word. The grammatical case is a change that takes place at the end of the word and transposes it between the syntactic features that a word takes such as nominative, accusative, genitive and jussive cases, according to the position of the grammarians, and the Fatha of the Hamza is given to the people of the desert, our study relates to the first meaning, which is an application of grammatical rules, and we have nothing to do with the other meaning. The syntactic plurality occurred as a result of multiple reasons that had a prominent role in the singular possibility of more than one grammatical aspect, some of them are related to advance, delay and multiplicity of the meaning of the composition, and some are related to the functions of the word, stopping and starting. &nbsp

After reviewing the books, literature and studies interested in sustainable development, as the tool was presented to arbitrators in the field of the research topic of sustainable development, methods of teaching, evaluation and building curricula to verify the validity of the tool, then the researcher prepared a list to analyze the content of the social studies books for middle school and found stability through analysis with himself، and the use of external analysts, using Cohen's kappa equation The reliability and validity were high, and the results of the research resulted in (32) recurrences and a percentage of (74.41%) for the third grade book and the second grade book for the same subject on (6) recurrences and a percentage of (13.95%). 5) And a percentage (11.62%) in light of the results. The researcher presented a set of conclusions, recommendations and suggestions. The researcher concluded the lack of dimensions of sustainable development in the social books of the intermediate stage for the first and second grades. He did not take into account the continuity of experiences and their integration between the third stages, and this indicates the existence of a gap between the sociology book for the third grade. and the previous two phases.&nbsp

Angle resolved photoemission spectroscopy of Sr_2CuO_2Cl_2 - a revisit

We have investigated the lowest binding-energy electronic structure of the model cuprate Sr_2CuO_2Cl_2 using angle resolved photoemission spectroscopy (ARPES). Our data from about 80 cleavages of Sr_2CuO_2Cl_2 single crystals give a comprehensive, self-consistent picture of the nature of the first electron-removal state in this model undoped CuO_2-plane cuprate. Firstly, we show a strong dependence on the polarization of the excitation light which is understandable in the context of the matrix element governing the photoemission process, which gives a state with the symmetry of a Zhang-Rice singlet. Secondly, the strong, oscillatory dependence of the intensity of the Zhang-Rice singlet on the exciting photon-energy is shown to be consistent with interference effects connected with the periodicity of the crystal structure in the crystallographic c-direction. Thirdly, we measured the dispersion of the first electron-removal states along G->(pi,pi) and G->(pi,0), the latter being controversial in the literature, and have shown that the data are best fitted using an extended t-J-model, and extract the relevant model parameters. An analysis of the spectral weight of the first ionization states for different excitation energies within the approach used by Leung et al. (Phys. Rev. B56, 6320 (1997)) results in a strongly photon-energy dependent ratio between the coherent and incoherent spectral weight. The possible reasons for this observation and its physical implications are discussed.Comment: 10 pages, 8 figure

Neutron Scattering study of Sr_2Cu_3O_4Cl_2

We report a neutron scattering study on the tetragonal compound Sr_2Cu_3O_4Cl_2, which has two-dimensional (2D) interpenetrating Cu_I and Cu_{II} subsystems, each forming a S=1/2 square lattice quantum Heisenberg antiferromagnet (SLQHA). The mean-field ground state is degenerate, since the inter-subsystem interactions are geometrically frustrated. Magnetic neutron scattering experiments show that quantum fluctuations lift the degeneracy and cause a 2D Ising ordering of the Cu_{II} subsystem. Due to quantum fluctuations a dramatic increase of the Cu_I out-of-plane spin-wave gap is also observed. The temperature dependence and the dispersion of the spin-wave energy are quantitatively explained by spin-wave calculations which include quantum fluctuations explicitly. The values for the nearest-neighbor superexchange interactions between the Cu_I and Cu_{II} ions and between the Cu_{II} ions are determined experimentally to be J_{I-II} = -10(2)meV and J_{II}= 10.5(5)meV, respectively. Due to its small exchange interaction, J_{II}, the 2D dispersion of the Cu_{II} SLQHA can be measured over the whole Brillouin zone with thermal neutrons, and a novel dispersion at the zone boundary, predicted by theory, is confirmed. The instantaneous magnetic correlation length of the Cu_{II} SLQHA is obtained up to a very high temperature, T/J_{II}\approx 0.75. This result is compared with several theoretical predictions as well as recent experiments on the S=1/2 SLQHA.Comment: Figures and equations are rearrange

Expanding frontiers in materials chemistry and physics with multiple anions

During the last century, inorganic oxide compounds laid foundations for materials synthesis, characterization, and technology translation by adding new functions into devices previously dominated by main-group element semiconductor compounds. Today, compounds with multiple anions beyond the single-oxide ion, such as oxyhalides and oxyhydrides, offer a new materials platform from which superior functionality may arise. Here we review the recent progress, status, and future prospects and challenges facing the development and deployment of mixed-anion compounds, focusing mainly on oxide-derived materials. We devote attention to the crucial roles that multiple anions play during synthesis, characterization, and in the physical properties of these materials. We discuss the opportunities enabled by recent advances in synthetic approaches for design of both local and overall structure, state-of-the-art characterization techniques to distinguish unique structural and chemical states, and chemical/physical properties emerging from the synergy of multiple anions for catalysis, energy conversion, and electronic materials
