The physisorption procedure and charge transfer phenomena are very important features in surface
physics, it contribute to many of important applications in solid state physics. Density functional
theory (DFT) with the package of Gaussian 09 at the basis set LanL2Dz, B3LYP level has been
utilized to attain the geometrical nanostructure, density contour maps, infrared spectra, electrostatic
potential, LUMO energy, HOMO energy, energy band gap, electron affinity, ionization potential,
density of states, dipole moment and the polarizability for the geometrical nanostructures (Cu9) ,(Cu10)
, (Cu9-OTS) ,(Cu9-Pyrimidine). Calculations of the geometrical nanostructure (Cu10-OTS) has been
accomplished at the basis set 6-31G , but the calculations of the geometrical nanostructure (Cu10-
Pyrimidine) has been accomplished at basis set LanL2MB. The interactions between the tosylate
(OTS) and the nanocopper surface leads to charge transfer phenomena. The interaction between
pyrimidine and the nanocopper surface leads to physisortion phenomena. Charge transfer phenomena
and physisorption precedures demonstrate apparently in the pictures of contour density maps.
Calculations of the energy band gap of the pure geometrical nanostructure (Cu9) and (Cu10) show that
the value of energy gap of those nanostructures is pioneering in the manufacture of the electronic
devices. Calculations of the ionization energy and electron affinity disclosure the best geometrical nanostructure to endow the electrons in an interaction, so the calculations disclosure the best
geometrical nanostructure to acquire the electrons in an interaction. Calculations of dipole moment and
polarizability disclosure the largest dipole moment and the highest activity geometrical nanostructure
in the research under the treatise. Physisorption procedure and charge transfer phenomena make all
hybrid geometrical nanostructures have the symmetry C1 . Physisorption phenomena makes some
geometrical nanostructures have anti-ferromagnetic features, but it makes other geometrical
nanostructures loses the anti-ferromagnetic feature.

The numerical analysis for the incompressible power-low inelastic fluid is described in this work. To
characterize the fluid's motion, a mass conservation equation and momentum conservation equation are
used. The investigation was carried out numerically using a Taylor Galerkin-pressure correction (TG-
PC) method. The contrast of Newtonian findings with shear-thinning inelastic is highlighted. The
convergence of solution components is examined under the variation of Reynolds number (Re) and the
parameters of power-low inelastic model (PLIM). The results show that the inelastic factors have a
considerable influence on the level of temporal convergence rates of velocity, while there is minor
change in the level of pressure convergence.

Background: Cinnamomum Zeylanicum, is one of the oldest herbal medicines and a popular spice crop
used in Asian countries. It has been valued for centuries for its distinct flavor and aroma, and it also
possesses various medicinal properties. In Cinnamomum Zeylanicum, there are many constituents such as
cimmaldehyde, eugenol, linalool and cinnamic acid. Therapeutic compounds found in plants are gaining
attention as a potential source for new drug development. Objectives : The study aims to identify
potential novel treatments for bacterial infections by evaluating commercially available ethanolic extracts'
in vitro antimicrobial activity and observing their effects on bacterial biological activity inhibition.
Material and methods: The well diffusion method was used to examine the in vitro antimicrobial
activity of an ethanol extract of Cinnamomum zeylanicum bark against both gram-positive (S. aureus and
S.epidermides) and gram-negative (E. coli and P. aeruginosa) standard microbes. In this study, all
pathogenic bacteria that affect humans tested were inhibited to varying degrees by the concentrations
investigated. Results:The results indicate that the inhibition zone for gram positive bacteria is greater
than that of gram negative bacteria at all concentrations, ranging from 19.22 (29%)mm to 18.44
(28%)mm against S. aureus and S. epidermids. The inhibition zones for E. coli and P. aeruginosa are
14.67 (22%) and 14.11 (21%) respectively. Conclusion: In this study, all pathogenic bacteria that affect

The main objective of this study was to evaluate of the neuroprotective potential effect of Ocimum
basilicum on amyloid protein expression in rat induced Alzheimer\'s disease. Fifty rats were divided into
five groups (ten rats each). Rats were treated orally with AlCl3 to induced AD. Group I (control group).
Group II (AD group): supplemented orally with AlCl3 (17mg/kg/day) for four weeks. Group III (O .b
/AD group) supplemented concomitantly with oral rivastigmine (3 mg/kg /day). Group IV (O .b/AD
group) supplemented concomitantly with oral OB (250mg/kg/day) and Group V (O. b/AD group)
supplemented concomitantly with oral O. b (500 mg/kg/day). The results showed that deposition of
amyloid protein expression was increased in positive group (AD induced rats) . Histological changes
were observed in brain tissues of AD rats. Minor deposition of amyloid protein (arrow) in cerebral
parenchyma was observed. However, the high dosing of the plant leaves extract (500 mg/kg) was more
powerful than the low treatment with low dose (250 mg/kg) by decreasing accumulation of amyloid
protein expression. The results suggest that Ocimum basilicum can relieve symptoms and prevent the
progression of AD severity by improving memory function. It can be concluded that OB leaves were
alleviated the memory impairment and learning abilities due to antioxidants activity of flavonoids,
tannins and terpenoids

Steganography, which is the science of delivering a message between parties in a way that an eavesdropper will not be aware that the message exists, is one of the key disciplines that have a considerable interest in fields. The suggested method seeks to conceal a smaller color image within a larger color image. It utilizes the transform domain throughout the steganography process to increase its resistance to changes and treatments made to the cover image. In order to achieve both complexity security and robustness, the project seeks to implement and utilize two techniques: ant colony optimization and transformation domain approach. The technologies under consideration suggest a Steganography method for digital photographs. It employs Discrete Cosine Transform (DCT) to achieve the same aims in terms of security, transparency and robustness. Additionally, it makes use of Once an Ant Colony Optimization (ACO) to increase robustness against signal processing attacks and imperceptibility in accordance with the human visual system. This work implements ACO for the cover to find the embedding locations on the graph path, and then finds locations to hide information based on threshold method, when looking for places to hide information blocks, DCT uses an intelligent block matching technique between the embedded image and the cover image, and both systems were tested against each other to compare their performance. Six stages make up the proposed secret key steganography system: test, transform, key creation and substitution, ant colony optimization, matching, inverse transform, and key encryption and concealing.

In this research, we studied the graded shielding using one of gamma-ray spectroscopy techniques, which consists of a scintillation detector sodium iodide activated by thallium NaI (Tl) with dimensions of 3"×3" and its electronic accessories .Shielding is fundamentally necessary to minimize the influence of ambient radiation, which consists of single or multiple layers of different materials, such as copper, aluminum and fiberglass, in addition to the lead shield manufactured with a thickness 3cm and through this work it led to reducing the values of the Compton edge and background scattering using industrial source of Cs-137. This method works to attenuate unwanted complications, which leads to reducing the count rates in some channels. These new layers should not contain any materials that would add new contributions to the radiation background, ultimately eliminating the complications resulting from the use of the lead shield.Theexperimental results and theoretical conclusion show consistent.
