The current study aimed to identify the effect of hybrid computing on internal control systems in Jordanian commercial banks, where the study community consisted of all Jordanian commercial banks listed on the Amman Stock Exchange, which is (13) commercial banks in 2019, and a comprehensive survey method was used in Choosing a study sample, as the sample included all of the study population. As for the inspection and analysis unit, which is (148), it consisted of individuals working in the higher administrative levels (general managers and executive directors), and the middle administrative levels (managers and heads of the divisions of the Information Technology Department, Risk Management and the Department of Internal Control) in the Jordanian commercial banks. For the purpose of analyzing study data and testing hypotheses, the Statistical Package for Social Sciences (SPSS) program was used in various statistical analyzes, where descriptive statistics and internal consistency factor (Cronbach alpha) were used as well. Multiple linear correlation test using Pearson correlation coefficient was used to test the presence of the Multicollinearity phenomenon, as well as Multiple and Stepwise Linear Regression. The study reached many results, the most important of which was the derivation of a unified concept of hybrid cloud computing, one of the most important dilemmas facing thinkers due to the difference in its characteristics and changing services depending on the model of its publication, as well as its continuous growing role in banks and companies as a development input which makes it applicable widely. Also, there was an emergence of the effect of hybrid computing (technology, finance, strategy requirements, organizational context, and risks) on internal control systems in Jordanian commercial banks. The most important recommendations are embodied in the need for Jordanian commercial banks to highlight the expected benefits from adopting hybrid cloud computing to build more positive attitudes towards that computing without neglecting their ease of use by finding the appropriate and suitable combination of their resources and technological capabilities to raise the efficiency of the control systems applied in them

ABSTRACT This article addresses control for the chaose anti-synchronization of a high frequency oscillator nuclear spin generator (NSG), which generates and controls the oscillations of the motion of a nuclear magnetization vector in a magnetic field. Based on the Lyapunov stability theory, an adaptive control law is derived to make the states of two identical (NSG) asymptotically anti-synchronized with uncertain parameters. Finally, a numerical simulation is presented to show the effectiveness of the proposed chaos anti-synchronization scheme

Titanium dioxide nanoparticles (TiO2 NPs) have novel application and are used in many household application, nanomedicine, agriculture, industries and pharmaceutical products. These applications may be accompanied with potential risk in human health and the ecosystems. The current study was carried out to find out the acute damage that might be induced by TiO2 NPs in the heart and testis. Three groups of Wistar albino rats (Rattus norvegicus) were subjected to a single dose TiO2 NPs (126, 252, 378 mg/kg bw). Cardiac and testicular biopsies from each animal under study were handled for histological and histochemical examination. Rats exposed to TiO2 NPs demonstrated the following cardiac alterations: myofibers wavy appearance, myofiber disarray, partial cross striation, cardiomyocytes hydropic degeneration together with vacuolation and nuclear alterations. Moreover, acute exposure to TiO2 NPs induced the following testicular alterations: spermatocytes degeneration, spermatids sloughing and interstitial edema. The presented cardiac and testicular alterations were dose dependent. From the findings of the present study, it might be concluded that TiO2 nanomaterials are capable of inducing acute cardiac and testicular damage which is dose dependent and could adversely affect the function of the vital organs

Silicon dioxide nanoparticles (SiO2 NPs) are widely invested in medicine, industry, agriculture, consuming products, optical imaging agents, cosmetics, and drug delivery. However, the toxicity of these NPs on human health and the ecosystem has not been extensively studied with little information is available about their behavioral toxicity. The current study aimed to find out the behavioral alterations that might be induced by chronic exposure to 10 nm SiO2 NPs. BALB/C mice were subjected to 36 injections of SiO2 NPs (2 mg/kg bw) and subjected to 11 neurobehavioral tests: Elevated plus-maze test, elevated zero-maze test, multiradial maze test, open field test, hole-board test, light-dark box test, forced swimming test, tail-suspension test, Morris water maze test, Y-maze test, and multiple T–maze test. Treated mice demonstrated anxiety-like effect, depression tendency, behavioral despair stress, exploration and locomotors activity reduction with errors induction in both reference and working memories. The findings may suggest that silica NPs are anxiogenic and could aggravate depression affecting memory, learning, overall activity and exploratory behavior. Moreover, the findings may indicate that these NMs may induce potential oxidative stress in the body leading to neurobehavioral alterations with possible changes on the vital organ including the central nervous system.

Silver nanoparticles (Ag NPs) are widely used in nanomedicine, pharmaceutical products, industry and other consumer products owing to their unique physiochemical properties with probable potential risk to human health and the ecosystems. The aim of this work was to investigate the in-life morphological effects, biochemical, histological and histochemical alterations that might be induced by variable sizes of Ag NPs in hepatic, renal and testicular tissues with the hypothesis that variable sizes of nano-Ag could induce variable effects in the vital organs. Five groups of adult healthy male mice (BALB/C) were exposed to 35 intraperitoneal injections of Ag NPs (1 mg/kg bw) using five different particle sizes (10, 20, 40, 60 and 100 nm). All mice were subjected to in-life morphometric, biochemical, histological and histochemical analysis. The findings demonstrated that Ag NPs could induce alterations in the average body weight gain, food consumption, water intake and organ indices. In addition, these NPs significantly altered hepatic and renal biomarkers. Moreover, Ag NPs produced ground glass hepatocyte cytoplasm, with mitotic activity, nuclear alterations, degeneration, glycogen depletion and inflammatory cells infiltration in the liver. The kidneys of treated mice exhibited proximal renal tubules degeneration, distal renal tubules regeneration, glomerular shrinkage, Bowman’s capsule thickening and interstitial inflammation. The testicular tissues demonstrated spermatocyte sloughing and spermatid giant cell formation. The findings together indicated that Ag NPs could interact with the anatomical structures of the liver, kidney and testis in ways that could induce injury. In addition, the results indicated that smaller Ag NPs posed a greater potential risk than the larger ones, which might be associated with their behaviour, dissolution rate, bioavailability and their probable variable toxicokinetics.

Metallic nanoparticles (NPs) are widely used in medical preparations. The present study aims to find out the influence of widely used five metallic NPs on the expression of major hepatic drug-metabolizing enzyme (DME) genes. Six groups of BALB/C mice, 7 mice each, were exposed to: Gold NPs, silver NPs, copper oxide NPs, silicon dioxide NPs and zinc oxide NPs, for 21 days. Liver biopsies from all mice were subjected to mouse cyp3a11, cyp2c29, ugt2b1 and interleukin-6 (il6) gene expression quantification using real-time polymerase chain reaction, in addition to inflammatory cell infiltration examination. All tested NPs caused a sharp and significant (ANOVA, p value <0.05) downregulation in the expression of DME genes, with the highest influence was observed in mice exposed to copper oxide NPs. Additionally, all NPs induced hepatic inflammation and upregulated the expression of il6 gene, which were inversely correlated with the expression of DMEs. It is concluded that all tested NPs downregulated the expression of DME genes, with the highest influence exhibited by copper oxide NPs, in correlation with inflammation and il6 gene induction in the liver. Further studies are needed to find out the effect of anti-inflammatory compounds against the alterations induced by metallic NPs exposure on hepatic DMEs

Titanium dioxide nanoparticles (Ti NPs) are widely used in many commercial products, nanomedicine, agriculture, personal care products, different industries and pharmaceutical preparations with potential risk in human health and the environment. The current work was conducted to investigate the renal damage that might be induced by the acute toxicity TiO2 NPs. A total of 40 healthy male adult Wistar albino rats (Rattus norvegicus) were exposed to TiO2 NPs (126, 252, 378 mg/kg bw) for 24 and 48 h. Fresh portions of the kidneys from each rat were processed for histological and histochemical alterations. In comparison with respective control rats, exposure to TiO2 NPs has marked the following glomerular, tubular and interstitial alterations including the followings: glomerular congestion, Bowman's capsule swelling and dilatation, inflamed glomeruli, renal tubules cloudy swelling, karyorrhexis, karyolysis, infiltration of inflammatory cells, congestion, necrosis, hydropic degeneration, dilatation and congestion of blood vessels, hyaline droplets and hyaline casts precipitation, interstitial edema and fibrosis. From the findings of the current work one may conclude that TiO2 NPs are capable of inducing kidney damage with more insulation in the cortex and the proximal convoluted tubules than the medulla and the distal ones respectively. In addition, it might be concluded that renal damage induced by these nanomaterials is dose and duration of exposure dependent. Further hematological, biochemical, immunohistochemical, and ultra-structural studies are recommended.

We report the whole ram genome of Jordanian Awassi (Ovis aries), screened using the power of Illumina HiSeq sequencing technology, providing insights into the ram's genomic structure. Generated data will help in the assessment of naturally occurring genetic variation and population structure of this sheep breed using different structure variation markers. Also, it will help in the established markertrait associations that can be used in marker-assisted breeding for qualitative and quantitative productive traits. A total of 23,812,247 single nucleotide polymorphism (SNPs) were identified, of which 177,117 (0.74%) were in the coding regions, as well as 3.77 million insertions/deletions and 3357 frame-shifting mutations in the coding region. The re-sequencing revealed 38,900 structure variation types distributed along genome, including 45 insertions and 16,643 deletions types. Also, there were 13,689 copy number variations, of which 3743 were up-regulated, and 9946 were down-regulated. These results will help in describing SNPs and the distribution of structural variations types used in genetic mapping and breeding programs of sheep breeds.

In this paper, with the help of the Lucas Riccati method and a linear variable separation method, variable separation solutions of the -dimensional modified dispersive water-wave system are obtained. We give the positive answer for the following question: Are there any localized excitations derived by the use of another functions? For this purpose, some attention will be paid to dromion, peakon, dromion lattice, multi dromion-solitoff excitations, regular fractal dromions, lumps with self-similar structures and stochastic fractal dromion structures based on the golden mean. By the novel definition of modified Weierstrass function, we discussed the stochastic fractal dromion structure.
