The compound stream event of March 20-25, 2011 as measured by the STEREO B spacecraft
...Show More Authors
Abstract<p>The interaction of interplanetary coronal mass ejections (ICME) with each other and with co-rotating interaction regions (CIR) changes their configuration, dynamics, magnetic field and plasma characteristics and can make space weather forecasting difficult. During the period of March 20–25, 2011, the Solar Terrestrial Relation Observatory (<italic>STEREO</italic> B) encountered a compound stream containing several interacting structures. Our analysis suggests that the stream consists of two ICMEs followed by an embedded ICME/CIR. The sudden appearance of the third ICME within the fast wind side of the CIR causes the proton temperature(<inline-formula><alternatives><tex-math>$T_{p} $</tex-math><math xmlns:mml="http://www.w3.org/1998/Math/MathML"><msub><mi>T</mi><mi>p</mi></msub></math></alternatives></inline-formula>) to drop suddenly to its lowest level in about 1.2 hours, from <inline-formula><alternatives><tex-math>$3.89 \times 10^{5}$</tex-math><math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mn>3.89</mn><mo>×</mo><msup><mrow><mn>10</mn></mrow><mrow><mn>5</mn></mrow></msup></math></alternatives></inline-formula> K to <inline-formula><alternatives><tex-math>$1.07 \times 10^{4}$</tex-math><math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mn>1.07</mn><mo>×</mo><msup><mrow><mn>10</mn></mrow><mrow><mn>4</mn></mrow></msup></math></alternatives></inline-formula> K (by a factor of ≈36). The fast wind which follows the CIR influences not only the third ICME’s temperature but also its proton beta (<inline-formula><alternatives><tex-math>$\upbeta_{\mathrm{p}}$</tex-math><math xmlns:mml="http://www.w3.org/1998/Math/MathML"><msub><mi>β</mi><mi>p</mi></msub></math></alternatives></inline-formula>). In addition, the third ICME impacts the CIR through expansion and deceleration. A forward pressure wave penetrates ICME1. It’s source is either the second ICME, the merged third ICME and CIR, or it may be a remnant shock. The compression causes an increase of the <inline-formula><alternatives><tex-math>$T_{p}$</tex-math><math xmlns:mml="http://www.w3.org/1998/Math/MathML"><msub><mi>T</mi><mi>p</mi></msub></math></alternatives></inline-formula> and <inline-formula><alternatives><tex-math>$\upbeta_{\mathrm{p}}$</tex-math><math xmlns:mml="http://www.w3.org/1998/Math/MathML"><msub><mi>β</mi><mi>p</mi></msub></math></alternatives></inline-formula> of the second and part of the first ICME. Despite the signatures of four large-scale interacting structures within the compound stream, it is difficult to reconcile the <italic>in-situ</italic> sequence with other remote sensing observations of ejecta close to the Sun because of the large system of coronal expanding loops above the active region. Compound streams therefore remain difficult to interpret, and further understanding of the subject will depend on the future study of similar events.</p>

Epidemiology of Some Parasitic Helminthes in Iraq from 2011 until 2015
...Show More Authors

Helminthes are among transmitting pathogens including Ancylostomiasis,
Ascariasis, Enterobiasis, Hymenolepiasis, Strongyloidiasis, Taeniasis, Trichuriasis,
Schistosomiasis, Echinococcosis. These helminthes have high effect on public
health in human population around the world. Iraq is one of the most important
endemic areas in the Middle East.The objective of this study is to determine the
prevalence of some parasitic helminthes in Iraq from 2011 until 2015. This study
was carried out in all Iraqi governorates from 2011until June, 2015.In 2015, the
results showed that 6 patients were infected with Ancylostomiasis, 89 patients were
infected with Ascariasis, 56206 patients were infected with Enterobiasis, 173patient

Mechanisms of Employing Secondary Event in Cinematographic Discourse: ماهر مجيد ابراهيم-شروق مالك حسن
...Show More Authors

  The cinematic story depends on many construction techniques that together constitute the story features technically and the secondary events are considered one of these basic techniques that are directly affected by the employment mechanisms inside the cinematic achievement. This subject initiated the two researchers to decide the title of the research: (Mechanisms of Employing Secondary Event in Cinematographic Discourse). The research is divided into an introduction that included the problem details, the aim and defining the terms used. The first section was the act and the event in the cinematic story, which addressed the relation between the act and the event and the nature of the simulation that tries to ascend the human act

Removal of toxic dye (Rhodamine B) from aqueous solutions by natural smectite (SMC) and SMC-nanoTiO2
...Show More Authors

Titanium oxide nanoparticles-modified smectite (SMC-nTiO2) as a low-cost adsorbent was investigated for the removal of Rhodamine B (RhB) from aqueous solutions. The adsorbents (SMC and SMC-nTiO2) were characterized by scanning electron microscopy, Fourier transforms infrared spectroscopy, and energy-dispersive X-ray spectroscopy. The effects of various parameters like contact time, adsorbent weight, pH, and temperatures were examined. Three kinetic equations (pseudo-first-order (PFO), pseudo-second-order (PSO), and intra-particle diffusion) were used to evaluate the experimental kinetic of the data and the results showed that the adsorption process is in line with the PSO kinetic model. Adsorption equilibrium isotherms were modeled using La

Abstract

To evaluate the effectiveness of Phenolic Compound of Salvia Frigida on induced atopic dermatitis (AD) of mice. Forty mice were included in the study, divided in to four groups (10 mice/group): apparently healthy, induced AD without treatment, induced AD treated with tacrolimus 0.1% ointment, and induced AD treated with Phenolic Compound of Salvia Frigida cream 5%. Examination of histopathology was done and skin homogenates levels also measured. Levels of WBC, Eosinophil, skin tissue homogenate of IL-13 and IL-4, serum IgE, and histopathological scores were significantly increased among induced non treated AD group in comparison with control group. Comparisons of non-treated induced AD
