An experiment was conducted in the green garden of Department of Biology/ in College of Education for Pure Sciences Ibn-Al-Haitham/ Baghdad University for the grouth season (2012-2013) to study the effect of three concentrations of gibberellic acid (0, 50, 100) ppm and three concentrations of proline (0, 25, 50) ppm on micronutrients content (Iron (Fe), Zinc (Zn), Manganese (Mn) and Copper (Cu) ppm) in addition to total chlorophyll content (µg. cm-2) for the green part of peas plant (Pisum sativum), pots of (8 kg) soil were used, the experiment was conducted according to complete randomized design (CRD) and three replicates, whereby the experiment included (27) pots, the significant variations were compared between means using least s

Show MoreIn this research, the mechanical properties of natural rubber blends in different proportions (70:30, 85:15, 100: 0 55:45 and phr) was studied through the use of two types of fillers (carbon black and titanium dioxide Nano) which show through tests conducted on the prepared models that increase fillers content which leads to improve the tensile properties (tensile strength, elastic modulus, elongation, hardness and compressibility). As shown by the results that the presence of polypropylene (PP) in the mix combination works to reduce the degree of intumescent and increase its content in the composition of mixtures which leads to get a great resistance to chemicals (acids, bases and oils).
In this work ,porous silicon(PS) substrate has been used to fabricate a sensor of structures(Al/n PSi/n-Si/Al) using infrared laser in a assisting Etching process at several times (8,16,and24 min) and current density(J) of about(25mA/cm2) on silicon(Si) substrates type of n and tested for CO2 gas molecules and then modulated using MATLAB program. J-V characteristic was analyzed. Different parameter determine such as, Porosity (%), Layer thickness (%) and relative permittivity of the fabricated PS substrate. Several shape and sizes of pores were obtained from the scanning electron microscope device such as pore, rectangular and cylindrical structure for infrared illuminated (IR). The Porosity (%) and Layer thickness (%) take control on se

Show MoreSilicon nanowire arrays (SiNWs) are created utilizing the metal-assisted chemical etching method with an Ag metal as a catalyst and different etching time of 15, 30, and 60 minutes using n-Si (100). Physical properties such as structural, surface morphology, and optical properties of the prepared SiNWs are studied. The diameter of prepared SiNWs ranged from 20 to 280 nm, and the reflectance in the visible part of the wavelength spectrum was less than 1% for all prepared samples. The obtained energy gap of prepared SiNWs was around 2 eV, which is higher than the energy gap of bulk silicon. X-ray diffraction (XRD) has diffraction peaks at 68.70o for all prepared samples. The heterojunction solar cell was fabricated based on the

The Photo- electrochemical Etching technique, (PEC) was used to produce porous silicon for n-type with orientation of (111). X-ray diffraction studies showed distinct variations between the fresh silicon surface and the synthesized porous silicon surfaces. Atomic force microscopy (AFM) analysis was used to study the morphology of porous silicon layer. AFM results showed that root mean square (RMS) of roughness and the grain size of porous silicon decreased as etching current density increased. The chemical bonding and structure were investigated by using fourier transformation infrared spec
... Show MoreAtorvastatin calcium (ATR) is an antihyperlipidemic agent used for lowering blood cholesterol levels. However, it is very slightly soluble in water with poor oral bioavailability, which interferes with its therapeutic action. It is classified as a class II drug according to Biopharmaceutical Classification System (low solubility and high permeability).
The present study aims to investigate the effects of duration and complications of type 2 diabetes mellitus on diabetic related parameters, adipocytokines and calcium regulating hormones. This study was conducted on eighty diabetic patients (41 male and 39 female) in Iraq, with an age range of 20-60 years and a disease duration range of 1-180 months. Blood samples were collected from the patients to determine three main types of biomarkers: diabetic-related parameters [Fasting blood sugar is FBS glycated hemoglobin (HbA1c), insulin, and insulin resistance (IR)], adipocytokines [adiponectin and tumor necrosis factor-α (TNF-α), and calcium regulating hormones [parathyroid hormone (PTH), calcitonin, and vitamin D].
