Air pollution evaluation of the operational processes in the East Baghdad oil field was carried out. The analysis was carried out by ICP-MS technique. Total Suspended Particles (TSP) air load was higher than Iraqi Standards and world international allowable limits of World Health Organization. The mean concentrations of gases carbon monoxide, carbon dioxide, sulfur dioxide, in the air were within national and world standards, while the mean concentration of nitrogen dioxide was higher than standard limits. The air of the study area is considered a good quality for CO, CO2 and NO2 with no health effect, while it is hazardous for TSP that have serious risk for people with respiratory disease. The mean concentrations of Cd, Cr, Cu and Co were higher than national and world limits due to operation processes and combustion of crude oil in the site while Ni concentration was within limits.

Pollution has been increased recently due to the activities of industries and agriculture, especially pesticides, heavy metals, and other toxic compounds that are usually considered as carcinogenic and mutagenic, materials need a long time to be degraded into simple forms. Therefore, it is a crucial to eradicate such pollutants from environments in different mechanisms from which the possibility of using microorganisms such as fungi. This mechanism then would be called mycoremediation. Such process should be known and practice to achieve clean and healthy environments. In this review article, we shed light on the definition, applications, advantages, and disadvantages of mycoremediation.

The optical properties of the TiO2 / Ag hybrid nanoparticles were improved as the particles were prepared with a pulsed liquid laser ablation (PLAL) technology. The effect of number of pulses (450) on the structural and optical properties of nanoparticles prepared in distilled water (DW) as growth media was examined using a Q-Switched Nd-YAG laser with wavelength (1064 nm), ablation energy (530 mJ) and repetition rate (1Hz). The distance between the target and the lens (10 cm). Several were used for the diagnosis such as X-ray diffraction analysis, fourier infrared transformations, TEM assays and fluorescence of the prepared samples. The results of X-ray diffraction analysis of the silver nanoparticles deposited on a glass slide showed that the crystal system is cubic and polycrystalline, with the direction being dominated by [111] at the level of the crystals. The results of X-ray diffraction analysis of a solution of titanium dioxide nanoparticles deposited on a glass slide revealed the presence of a quadrangular crystal system, indicating the presence of titanium dioxide particles in (rutile), and that the prevailing trend for crystalline levels is [110]. The functional groups of (TiO2 / Ag) were determined in the liquid medium by the (FTIR) technique. Also, TEM images showed the presence of nanoparticles and microparticles in an almost spherical shape. The fluorescence measurement of (TiO2 / Ag) hybrid particles showed that through the graph the peak values of (284.1) and (418.3) nm. This is roughly identical to the absorption spectrum results of a hybrid silver and titanium dioxide nanoparticle solution.

Simple, inexpensive, and high sensitive Lateral Flow Immunoassay (LFI) based colloidal gold nanoparticles antigen-coated as the label was designed for the fast determination of organophosphorus pesticide in cow’s milk samples. The developed LFI detection strip consisted of four structural zones start from the sample pad, conjugate pad, detection zone, and finally absorbent pad. Immune-sensitive zone was synthesized and functionalized with Propanoic Hapten–OVA, Goat monoclonal-anti-Propanoic antibodies were produced. Propionic -cationized ovalbumin-HPR conjugates were fabricated and identified. The antibody optimal conditions were set and the influence of pH on the analytical properties of the antibody-based gold nanoparticles was also investigated. The detection limit of the LFI for Propanoic standard into milk samples were 0.5 and 100 ng/mL, respectively. The test development time for the LFI was less than 5 min, suitable for fast on-site measuring of Propanoic.

Celiac disease is an inflammatory disorder involving the small bowel, in addition to other organs. An inappropriate immune response to dietary gluten mainly in genetically predisposed individuals lies behind the persistent inflammation of the mucosa lining the proximal small bowel. Malabsorption in celiac disease patients lead to deficiencies in a number of minerals and vitamins. Among the affected vitamins is vitamin D. The present study aimed to figure out the prevalence of vitamin D deficiency in celiac disease patients and investigate whether any vitamin D deficiency could associate with the level of autoantibodies. Forty-six early diagnosed celiac disease patients (11 males and 35 females) were consecutively recruited from Special Nursing Hospital \\\\ Baghdad, during the period from July 2018 to February 2019. Twenty apparently healthy subjects were also recruited to serve as a control group. Age distribution of patients showed that 43.7% of patients were between 10 and 20 years old. On the other hand, 6 (13%), 1 (2.1%) and 4 (8.6%) patients were in the age groups 20-30, 30-40 and 40-50 years respectively. Female patients were more than male patients (66 and 34% respectively). Celiac disease patients had a significantly lower level of vitamin D in comparison with the control (14.3 ±9.9 and 68± 4 ng/ml respectively). In addition, 71.73% of celiac disease patients had vitamin D deficiency, 23.91% had vitamin D insufficiency, while 4.34% of celiac disease patients had vitamin D sufficiency.

Through this paper we define the higher triple left resp. right centralizers of a Γ-ring Ɠ, and study some properties of Jordan higher triple left resp. right centralizers of Ɠ, addition to we prove that: every Jordan higher triple left resp- right centralizer of a Γ-ring Ɠ is higher triple left resp. right centralizer of Ɠ when Ɠ is a 2-torsion free prime gamma ring.

Let R be a ring with identity and Q be a unitary left Module over R. In this paper, we introduced the concept of p-semi hollow-lifting Module as generalization of semi hollow-lifting Module. Also, give a comprehensive study of basic properties of p-semi hollow-lifting Modules and some related concepts.
