    Der Glaube an Gott in Bibel und Koran

    Get PDF
    Das arabische Wort Allah entspricht dem deutschen Wort "Gott". Dabei handelt sich nicht nur um einen Eigennamen Gottes, also lediglich um eine Form der Anrede, sondern um den Begriff "Gott" in seinem vollen Inhalt. So verwenden auch die arabischen Christen für Gott das Wort Allah. Sprachlich besteht ein Zusammenhang mit dem hebräischen Elohim, aramäisch Aloy = Allah = Gott. Hier ist zu unterscheiden zwischen Allah und Ilah, wobei das letztere Wort für irgendeinen Gott steht, Allah aber für den einen bestimmten und einzigen Gott, der nach der islamischen Lehre schon im Juden- und Christentum bekannt war. Wenn der Prophet Muhammad von Allah spricht, ist daher immer dieser eine und einzige Gott gemeint und nicht eine unbestimmte Person unter mehreren. Im Begriff Gott ist also eine gemeinsame Grundlage des Judentums, Christentums und des Islam gegeben. Allerdings haben die Bibel und der Koran verschiedene Vorstellungen von Gott, was besonders in der Beschreibung seiner Eigenschaften zu Tage tritt. ..

    Development of Models to Predict Highway Fatality Rates: Insight from United States, Southern States, Gulf Mexico States, and Louisiana

    Get PDF
    This study has two main objectives. First, the impact of various factors on highway fatality rates in the United States (US), Southern States, Gulf Mexico States, and Louisiana are examined. Second, two models are developed to predict fatality rates in the stated regions: highway fatality rate per 1000 drivers and highway fatality rate per 100 million vehicle miles traveled (VMT). Data from 2004-2021 obtained from the Bureau of Transportation Statistics are analyzed using Stepwise Multiple Regression method. The results of this study reveal that road conditions and driving alone are the primary predictors strongly associated with fatality rates. The impact of other factors, such as commute modes, highway expenditure, and transportation employees, is also observed to varying degrees. The predictive models are validated using the Shapiro-Wilk test and normal distribution plots to ensure accuracy. This study\u27s findings will aid decision-makers in allocating resources and improving highway safety in the US

    Novel Characteristics of Murine Bone Marrow-Derived Macrophages and Human Macrophage-Like Cells

    These studies provide evidence for novel properties of macrophages derived from bone marrow stem cells. In study 1, treatment of activated mouse bone marrow-derived macrophages (BMM) with either catecholamine synthesis inhibitors (α-methyl-para-tyrosine and fusaric acid) or the β2 adrenergic receptor antagonist ICI 118,551 demonstrated that BMM produce catecholamines. The catecholamines modulated macrophage cytokine production through autocrine actions on adrenergic receptors. In study II, undifferentiated human bone marrow cells were incubated in 30% mouse L929 fibroblast conditioned medium and generated adherent cells within three days. The cells were clearly identifiable as macrophages based on surface proteins and phagocytic activity but produced only low levels of the cytokines tumor necrosis factor-α and interleukin-lβ. Cytokine production did not increase in response to the bacterial endotoxin lipopolysaccharide (LPS). Generation of these macrophage-like cells was not repeatable with other samples of human bone marrow, but the cells continue to proliferate in cell culture and will be investigated further in future studies

    Discontinuous Sturm-Liouville Problems and Associated Sampling Theories

    Get PDF
    This paper investigates the sampling analysis associated with discontinuous Sturm-Liouville problems with eigenvalue parameters in two boundary conditions and with transmission conditions at the point of discontinuity. We closely follow the analysis derived by Fulton (1977) to establish the needed relations for the derivations of the sampling theorems including the construction of Green's function as well as the eigenfunction expansion theorem. We derive sampling representations for transforms whose kernels are either solutions or Green's functions. In the special case, when our problem is continuous, the obtained results coincide with the corresponding results in the work of Annaby and Tharwat (2006)

    Molecular markers for drought tolerance in bread wheat

    Get PDF
    Random amplified polymorphic DNA (RAPD) primers associated with drought tolerance was used in this study to characterize drought tolerance in six wheat genotypes with developed marker assisted drought tolerance. Four of them were tolerant and two were drought sensitive genotypes. The results indicate that tolerant genotypes harbored seven positive RAPD markers, while sensitive genotypes had only one negative RAPD markers. In tolerant genotypes, seven positive PCR-RAPD markers with molecular sizes of 1050, 390, 200, 230, 850, 430 and 800 bp was exhibited by A-12, B-05, C-12, E-10 and B-02 primers. This study indicates that the seven positive markers can be used as indicators to discard drought tolerance in wheat marker -assisted breeding programmes.Keywords: Drought tolerance, PCR analysis, RAPD primer, wheat genotypesAfrican Journal of Biotechnology Vol. 12(21), pp. 3148-315

    The Degree of Availability of Leadership Skills for School Principals from the Point of View of Teachers in the Sultani Dam Affiliated to the Qatraneh Brigade

    Leadership plays a major role in the effectiveness of the educational system, and this requires educators to develop their performance in terms of management or leadership. Through this study, the researcher sought to find out the degree of availability of leadership skills for school principals from the point of view of teachers in the Sultani Dam affiliated to the Qatraneh Brigade. It sought to determine the significance of the differences in the responses of the study sample according to some demographic variables (gender, years of service, and educational qualification). To achieve the objectives of the study, the descriptive analytical method was followed and the Likert scale was adopted. A stratified random sample of teachers was selected, numbering (50) male and female teachers, and a questionnaire was used as a tool to collect data consisting of the axis (leadership skills), after verifying its validity and stability, and then applying it to the basic study sample, where it was found that there are significant differences Statistical (a = 0.05) attributed to the effect of gender, where the value of P-value amounted to 4.779, with a statistical significance of 0.034, there were no statistically significant differences (a = 0.05) due to the effect of years of service, where the value of P-value amounted to 1.059, and there were no statistically significant differences (a = 0.05) due to the effect of educational qualification, where the value of is 0.623. According to these results, a set of recommendations were presented, including: Urging school principals to link the teachers’ development plan professionally with the school’s vision, mission, mission and goals, in order to achieve greater activation of future planning within schools, as well as directing school principals towards building a common vision among teachers about the development of school work.

    Bio-imaging and serum analysis of zinc and other trace elements in a study of age-related diseases using inductively-coupled plasma mass spectrometry

    Trace elements participate in numerous biological processes and understanding their activity is essential in monitoring various diseases. Zinc has long been recognized as a fundamental component of various tissues, being highly concentrated in the retina and an essential structural component of many proteins. It plays a crucial role in many biological activities including homeostasis, immune function, oxidative stress, and aging disorders. During aging, the systemic metabolism of iron, zinc and copper changes, and this disruption in metal homeostasis appears to be associated with age-related disorders such as Alzheimer s disease (AD) and Age related macular degeneration (AMD). As understanding the role of these metals is critical in finding the underlying causes for such diseases, and providing proper diagnosis and treatments, the distribution of these crucial elements in AD and AMD has been investigated. A rapid, accurate technique using sector field inductively coupled plasma mass spectrometry (SF-ICP-MS) was developed for the preparation and analysis of small volume (30 µl) biological samples. Analytical performance was evaluated using Serum UTAK certified reference material and the method was applied to Zn, Cu and Fe determination in 81 human serum samples from AD and AMD patients. No significant difference was found in Zn and Cu levels between AD and AMD patients, whereas Fe in AMD patients was slightly higher than AD patients. The results showed a decrease in serum Zn and Fe, and a notable increase in serum Cu in both AD and AMD patients compared to healthy controls. Elemental bio-imaging using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was successfully employed for Zn imaging in 12 rat retina sections given either a conventional or a Zn-containing diet. A new data processing method, involving fitting Gaussian peaks to individual LA-ICP-MS line scans, was established. The RPE/retina peak area ratio was used to evaluate the differences in Zn content between supplemented and non-supplemented rats. In general, the difference between the three differentially fed rat groups was not statistically significant for the relatively small group of twelve rats investigated here. Thickness of Zn bands was also found to vary between controls and supplemented rats. This technique has the potential to support biologists in recognising possible new biomarkers for disease, related to specific trace elements

    The application of streamline reservoir simulation calculations to the management of oilfield scale

    Get PDF
    Inorganic scale may precipitate in oilfield systems, down hole in the reservoir, in the production flow tubing, and in surface facilities, as a consequence of thermodynamic changes that affect the flowing brines. These changes may be induced by temperature or pressure changes, or by mixing of incompatible brines. While much work has been performed to study the effect of thermodynamic changes such as pressure decrease or temperature increase on scale precipitation, it is only recently that a body of work has been developed on the impact that the dynamics of brine mixing in the reservoir has on scale precipitation in situ. Much of this work has been conducted using finite difference simulators, which are handicapped with regard to these calculations in that numerical dispersion effects can be orders of magnitude greater than physical dispersion. The introduction of chemical reaction calculations into streamline simulation models presents a very significant opportunity for improving the accuracy of such calculations. While numerical dispersion effects for immiscible calculations (eg water displacing oil) can be countered by pseudoisation of the relative permeability functions, in finite difference models it is difficult to control numerical dispersion for miscible displacements e.g. seawater (with a Sulphate concentration) displacing formation water (with a Barium concentration), which may lead to scaling in the reservoir (Barium Sulphate precipitation). Streamline simulation reduces the numerical errors for both miscible and immiscible displacement, thus making the scaling calculations much more accurate. The objective of this PhD project was to study the application of a streamline simulator, which has the appropriate chemistry modeling capabilities, to realistic reservoir scenarios. The project consisted of two stages: 1) Study of synthetic systems to identify the impact of brine mixing in simple scenarios (eg single layer and multi-layer quarter five spot patterns) 2) Application of the technique to full field reservoir systems to improve the capability of making scale management decision during the project Front End Engineering and Design (FEED) phase. The calculations performed demonstrate where, and under what conditions, scale precipitation takes place in situ in the reservoir, and what the resulting impact on the chemical composition of the produced brine will be. This information is key in the planning of the management of oilfield scale
