Localization of transforming growth factor-beta expression in the peri-implant tissues of dental implants coated with placental collagen
...Show More Authors

Back ground : The transforming growth factor beta (TGFB) signaling pathway is involved in many cellular processes in both the adult organism and the developing embryo including cell growth, cell differentiation, apoptosis. The interaction between implant material and surrounding tissues is believed to play a fundamental role in implant success and illustrates different expression of growth factors by different cells that involved in the formation of peri-implant tissue. The aim of this study was to localize expression of TGF B by newly formed bone tissue around surface-conditioned implants with placental collagen at different time intervals: 3 ,7,14,28, and 56 days . Materials and Methods: Commercially pure Titanium (CPTi) implants coated with collagen protein were placed in the tibia of 20 new Zealand rabbits . Immunohistochemical study for localization of TGF B in peri –implant tissue for interval periods 3 ,7,14,28, and 56 days was performed under light microscope.. Results: Positive expression of Transforming growth factor B can be detected in osteoblast, osteocyte, newly deposited matrix includes collagenous tissue and non mineralized osteoid tissue. Endothelial cells line blood vessel showed positivity too. Minerlized bone trabeculae and mature bone illustrate negative expression. Conclusion: The present study suggests that placental collagen, coated Ti implant illustrates positive expression of transforming growth factor B by osteoblast and endothelial cell that enhanced bone formation.

The effect of usage two methods of garlic extraction( foliar and ground application) on the growth of the tomatoes (Solanum lycopersicum) plant
...Show More Authors
Abstract<p>Garlic is rich in nutritional and medicinal value as it has been found that the water extract of garlic plant contains 31% carbohydrates and rich in elements calcium, phosphorus, magnesium, potassium, sodium, iron, zinc, manganese, vitamin C, thiamine, riboflavin, niacin and pyridoxine. The aim of this study was to investigate the effect of garlic extract (<italic>Allium sativum</italic> L.) on tomatoes (<italic>Solanum lycopersicum</italic> L.) plant. The trend is to use plant extracts in foliar and ground fertilization. Three levels of foliar application (4, 6, 8%), three levels of ground application (10, 20, 40%), one treatment 6% of foliar and 20% ground applic</p> ... Show More

Investigation of density and form factor of some F isotopes using Hartree-Fock and shell model calculations
...Show More Authors

Structure of unstable 21,23,25,26F nuclei have been investigated
using Hartree – Fock (HF) and shell model calculations. The ground
state proton, neutron and matter density distributions, root mean
square (rms) radii and neutron skin thickness of these isotopes are
studied. Shell model calculations are performed using SDBA
interaction. In HF method the selected effective nuclear interactions,
namely the Skyrme parameterizations SLy4, Skeσ, SkBsk9 and
Skxs25 are used. Also, the elastic electron scattering form factors of
these isotopes are studied. The calculated form factors in HF
calculations show many diffraction minima in contrary to shell
model, which predicts less diffraction minima. The long tail

Experimental Investigation of Crack Initiation and Growth in Concrete Slabs Placed Directly on Clayey Soil
...Show More Authors

The main objective of this study is to examine the impact of moisture concrete of clayey soil on the concrete slabs placed directly over it. This experimental study presents the mechanical properties of the concrete slab when placed on different clayey soil moisture content ranging from 0% to the optimum moisture content of 35%. The tests were performed on soil concrete specimens of 25*30*50 mm exposed to sprayed water curing conditions for 28 days. Tests of compressive strength, ultrasonic pulse velocity, crack depth and crack width were investigated through this paper. An ejection relationship between compressive strength of concrete and water content in the soil was observed, with a 26% increase with water increasing from 0% to 35%. T

STRAWBERRY CV. FESTIVAL GROWTH IN RESPONSES TO MAGNETIC WATER AND FOLIAR APPLICATION OF COCONUT EXTRACT
...Show More Authors

This study was carried out to study effect of magnetic water ( M0 and M) and different concentrations of coconut extract in Fragaria x ananassa (Duch) C.V Festival. The results showed significant differences in the plants treated with magnetic water ( 0.12 Tesla) and different concentrations of coconut extract C1 (0%), C2 (2.5%), C3 (5%), C4 (7.5%) and C5 (10%) in vegetative parameters as in leaf area and chlorophyll in treatment M0C3 was (53.72 Dcm2, 50.00), respectively, highest leaf number and plant dry weight in MC4 (12.77,14.22 gm), respectively. Results recorded significant differences in fruit parameters such as weight in MC1 (18.97 gm). The maximum fruit number was in MC3 (110), the greatest fruit size was in MC4 (15.78 cm3) and the

Crystal Growth of High – Purity Bi2Se3 and Study of Crystal Structure
...Show More Authors

The Bi2Se3 compound was synthesis by fusing initial compounds consisting of
extra pure elements in stoichiometric ratio from elements compound, charged inside
quartz ampoule. The crystal growth of Bi2Se3 carried out using Brighaman technique

of Bi2Se3 has been grown in direction (211) after slow cooling on account of heat
gradient to zone furnaces at cooling rate (1-3) C/hr. The structure study of the compound
was determined by x-ray diffraction technique, which it has bismuthinite structure and
orthorhombic unit cell with lattice parameters of a=10.2678 Å, b=11.2392 Å and
