The electronic properties of single walled carbon nanotubes (SWCNTs) influenced by the mechanical elastic deformation are investigated by using a tightbinding approximation. We analyze the band structure for SWCNTs in a wide range of energies around a Fermi energy level. Our work includes the uniaxial, torsional and sublattice deformation, which is applied to modify the electronic transport properties of SWCNTs, e.g. the energy spectrum as a function of the deformation tensor. However, the results showed that the electronic properties of SWCNTs are affected by deformation processes, where the energy spectrum is changed perceptibly.

Polymeric materials containing the soap of The Beta vulgaris have not been
studied and applied to a variety of antimicrobial-relevant areas.
The soap of The Beta vulgaris was prepared using the ordinary cocking method. The
soap was mix with polyurethane foams in to ways but one of the two ways produce a
weak polymer matrix.
In order to know the activity of the soap of The Beta vulgaris as an antimicrobial
agent mixed with polyurethane foam. The types of microbes were used.
Susceptibility was determined by the Kirby Bauer disk diffusion method Bacteria
(Staphylococcus auras, Escherichia coli) and Fungi (Candida albicans) were grown
on nutrient broth at 37C overnight
The obtained results show no clear inhibition zone for the three microbes. The
amazing result is that the soap of The Beta vulgaris is working as a biodegradation
agent that when mix with the foam of polyurethane will produce a biodegradable
polymer foam.

Digital Watermarking is one of the techniques to hinder the unauthorized use of
digital media. This technique can help the protection of proprietorship rights toward
ensuring the copyright information and authentication in a networked environment.
Inspired by combining Discrete Wavelet Transform (DWT) with modification of
Singular Value Decomposition (SVD). Digital image watermarking technique based
on the encryption algorithm is proposed in the present work in order to improve the
robustness, security and the imperceptibility. The watermark image is encrypted by
using Advanced Encryption Standard (AES) encryption technique with a secret key
and then transformed the original (host) and watermark images using DWT and
modified SVD for embedding the encrypted watermark in the high frequency sub
band (HH) of the original (host) image. The experimental results show that the
proposed method is superior from where robustness, imperceptible and security as
compared with some related methods.

Deep beams with rectangular (R) and T- cross sections that have web openings are widely used in
concrete structural field for servicing purposes. This situation should be treated with special care
depending on the type of the load subjected and the location of the opening. This study is aimed to
investigate the ultimate load; carrying capacity of indirectly loaded deep reinforced concrete (RC)
beams through an experimental and analytical program. The experimental work has two parts of
specimens, where the six deep beams have ratio of shear span- to- effective depth (a/d) is 1.0 have been
consider. The first part consists of two deep beams with rectangular and T- cross sections, which formed
without web opening, with vertical web reinforcement. The second part consists of four deep rectangular
and T-beam cross sections in which, all beams have openings in the shear span, with deferent
reinforcement arrangements. The behavior of deep beams was observed, cracking and ultimate loads.
The experimental results indicate that the web opening in the shear span of the beams shows a
significant reduction in the ultimate load capacity. For predicting the ultimate load carrying capacity for
deep beams with opening, Eq. of Kong & Sharp (1977) used. Comparison between experimental finding
and numerical results showed a good agreement with experimental results of ultimate load capacity of
beams with opening.

Due to the stunning characteristics of cloud computing, such as tremendous
scalability, elasticity, cost-efficiency, pay-as-you go, and storage solutions, many
enterprises and individuals are motivated to outsource their data to cloud service
providers for availing its benefits. Protecting and preserving the privacy of these data
represent a persistent barrier from adopting the cloud computing. Mining the cloud
data may be misused for a variety of purposes. To counter this problem, we propose a
secure framework for mining the cloud data in a privacy preserving manner. Secure k
Nearest Neighbor (kNN) classifier is used in this paper.
In this work, we preserve all the restrictions that we specify privacy and
success to exclude the third party from the mining process. We test our secure
classifier with different parameters to explain its influence on the accuracy and
privacy the suggested classifier.

The radioactivity levels of238U, 232Th, 40K and 137Cs were determined in 17brands offlour (6 brands) and
macaroni(11 brands) consumed in Basrah, Iraq.This papershowed a comparison of the gamma absorbed
dose rates (D),annual effective dose equivalent (AEDE)and the excess lifetime cancer risk (ELCR)for
various types offlour and macaroni measured by SAM940-2G operating with BNC 2ʺx2ʺ gamma-ray
NaI(Tl) detector along withthe thermoluminescencetechnique. For flour samples, the minimum specific
activity values of 238U, 232Th, 40Kand 137Cs were 0.238±0.002 Bq/kg (at sample F1), 0.117±0.001 Bq/kg(at
sample F4), 3.529±0.001 Bq/kg(at sample F4) and 0.040±0.007 Bq/kg(at sample F3) respectively, while the
maximum values of the same isotopes were 0.325±0.002 Bq/kg(at sample F3),1.469±0.002 Bq/kg(at sample
F5),102.348±0.001 Bq/kg(at sample F6) and0.179±0.003 Bq/kg(at sample F2) respectively. For macaroni
samples, the minimum specific activity values of 238U, 232Th, 40Kand 137Cs were 0.195±0.002 Bq/kg(at
sample M2),0.029±0.004 Bq/kg(at sample M1),40.390±0.001 Bq/kg(at sample M6)and0.01±0.008 Bq/kg(at
sample M11)whereas the maximum values of the same isotopes were 1.430±0.002 Bq/kg(at sample
M3),2.629±0.002 Bq/kg(at sample M11),294.495±0.001 Bq/kg(at sample M10) and0.566±0.002 Bq/kg(at
sample M4).Various radiation hazard indices including the radium equivalent activity (Raeq), the ingestion
effective dose (HT,r), the internal hazard index (Hin), the external hazard index (Hex), the gamma index (Iγ)
andthe alpha index (Iα) have been determined for all 17 samples. Allachieved results have been found to be
undertheinternationallimit standards. Thus, selected flour and macaronitypes are safe to be consumed in
Basrah governorate. The findings of thisstudycould be used as a first step to create radiological baseline data
of the hazard radiation in basic foodstuffsconsumed in Basrah/Iraq.

We use the Newns-Anderson model to study the chemisorption process for hydrogen atom on
perfect graphene. The self-consistent solutions for hydrogen atom occupation levels show that the
physical solution is magnetic for all normal distance values from the graphene sheet. And the
metallic part of the chemisorption energy is the dominant one for all distance values, which gives
the obvious description to the type of hydrogen bonding formed with the graphene.

Estimating the physical properties of water-bearing layers is an essential part of
groundwater studies. One of the most effective ways of determining these properties is to
conduct and analyze aquifer tests. The aim of this research is to carry out hydrogeological
investigation in Khanaqin basin within Diyala Governorate in the east of Iraq to calculate
hydraulic parameters of the most important product groundwater aquifers. Cooper-Jacob
and Theis Recovery test methods were used to calculate transmissivity and storage
coefficient after field investigation of aquifers extended in the basin. The geographical
position, elevations, static water levels, depths, thicknesses and maximum yields were
carried out during field work. The results showed that Khanaqin basin has two geological
units represented by unconfined and confined aquifers, where (4) wells were used in
pumping test. The average transmissivity parameter was ranged between (273-4590
m2/day) in unconfined aquifer while this range was (14.47-244.35 m2/day) in confined
aquifer. Transmissivity contour map indicated increasing value of this parameter towards
northern west direction of the Khanaqin basin. Storage coefficient ranged between
(3.5*10-5) to (1.14*10-3). The increasing of transmissivity parameter as groundwater
movement generally flow towards the northern west leading to increase groundwater
discharge from wells penetrate unconfined and confined aquifers.
