The importance of a database relies in saving information to benefit from
retrieving, processing, hiding, declaring them depending on necessitous. In this
research, information represents the coordinates of different curve points, these
curves are path for aircraft on air or railway or launch of rocket path or tunnel or
tracing path in desert and many of important paths ,all can be considered as
curves, these curves have been taken and saved as binary images then begin to
search for the beginning point of this curve (the point with different color that have
only one neighborhood ) ,saving this point in a database that have been
constructed for this purpose ,then changing the point color to be the same as the
background ,continuing tracing the curve points until the end zone (that have no
neighborhood ) to have a database to be benefit from it in security operations by
hiding important paths(military tunnel, oil pipe) knowing only to those owning the
related database

This study was performed to investigate the effects of cinnamon extract on of
blood glucose as well as serum insulin and testosterone hormones. The experiment
was carried out on twenty four male adult mice distributed into 4 groups of 6 mice
each. Group one was kept as positive control, while mice of the other three groups
were given orally an aqueous cinnamon extract at 0.5, 1 and 2mg/ml respectively,
daily for three weeks. The results showed that oral administration of cinnamon
extract at 2 mg/ml to diabetic male mice for three weeks decreased blood glucose
level and increased serum insulin and testosterone levels. This study recommends
that intake of cinnamon bark as a drink may be beneficial for diabetic patients who
suffer from sexual impotency as their extracts induce antidiabetic activity and
enhance male fertility in diabetic mice.

This work reports the attempts to carry out pulsed laser ablation in liquid (PLAL) for
synthesizing colloidal copper oxide nanoparticles (NPs). Copper oxide NPs was
synthesized by 7ns Nd:YAG laser ablation of high purity copper target immersed in
different solutions; ethanol, acetone, and water. The optical and morphological properties
of copper oxide NPs were investigated. It was found that the optical absorbance, energy
gap, size, and distribution of copper oxide nanoparticles are dependent on liquid type.
Plasmon peak was observed at 550nm for Cu NPs ablated in acetone and methanol
liquids, while it was disappeared for those ablated in water. Atomic Force Microscopy
(AFM) analysis showed that the average grain size of copper oxide particles ablated in
acetone, ethanol, and water were 276 nm, 300, and 360nm, respectively. Fourier
Transform Infrared (FTIR) was used to study the vibrational frequencies between the
bonds of atoms for a synthesized copper oxide NPs at different liquids. All these results
confirm the complete oxidation of ablated copper.

The objective of this study was to isolate and identify bacteria found in natural
association with adults of Musca domestica.In this study adults of Musca dometica
were collected from four sites in Sulamani city,Kudistan,Iraq to isolate and identify
bacteria on the external surface of house flies . Bacteria from fly samples isolated
using the conventional isolation technique were E.coli , Pseudomonas aeruginosa ,
Staphylococcus albus , Staphylococcus aureus , Salmonella sp. and Klebsiella sp. The
results of current study confirm that the houseflies are much more than nuisance and
they pose potentially serious health risks. Consequently, the population of houseflies
has to be controlled.

correlated to the size of the nano-scale. The FTIR spectra for porous silicon are
shown that the dominant bonds being Si-H groups

In this work, CdS nanoparticles were synthesized via chemical method using
thioacetamide (TA). X- ray diffraction (XRD), Atomic force microscopy (AFM) and
UV-VIS transmission spectroscopy were employed to characterize the size,
morphology, crystalline structure and optical properties of the prepared material. X-ray
diffraction analysis confirms the formation of cubical and hexagonal structures of CdS
nanoparticle with average particle size (3.2nm). AFM show the formation of aggregate
of nanoparticle with particle size ranging 7 – 20 (nm). From the shift in optical band
gap, particles size can be calculated using Effective mass approximation (EMA) was
(2.3nm), and found a good agreement with those determined from XRD broadening,
while AFM show higher particle size due to aggregation of nanoparticles

The main objective of this study is to determine the concentrations of
Interleukine-6, Vitamins A, E, and C in patients with FMS. This study included
60 patients with FMS were diagnosed according to the American college of
Rheumatology (ACR) 1990 criteria. They were obtained from the people
attending the Rheumatology & Rehabilitation Consultation Unit / Out Patient
Clinic/ Baghdad Teaching Hospital in Medical City. Their ages range were 20-60
years and their ages range were then matched by age and sex to 30 healthy
control persons with mean age 43.25 ± 3.16 years. Results revealed that there was
no significant difference in the mean value of IL-6 in serum of patients with
FMS, while vitamins A, and E concentrations in serum of patients with FMS
were significantly decreased as compared to the level in serum of healthy controls
(p>0.05), and the mean values of Vitamin C concentration in serum of patients
with FMS were significantly increased than the level in serum of healthy control
(p< 0.05).

The experiments were conducted, to study the effect of 3 concentrations of
each of indole butyric acid (25,50 or 100 ppm )and Mepiquat chloride
(125,250 or 500 ppm ) on the active ingredients content of Petroselinum
hortense L.
The experiments were designed in RCBD, and each treatment was replicated
3 times. L.S.D. test at level of 0.05 was used to compare the differences
between means.
Result showed that the percentage of active ingredients of the plant extracts
(essential oil , coumarin, flavonoids),were significantly increased with the
increase of indole butyric acid compare with control treatment. However,
application of Mepiquat chloride decreased them compare with control
treatment.
Indole butyric acid increased endogenous gibberellic acid(GA) and indole
acetic acid(IAA) while Mepiquat decreased them. This study proved that
growth regulators of the plant as a natural tool to increase active ingredients for
their medical value.

Recently LED display panels are widely used throughout the world in all
situations to create images for visual displays in a variety of applications including
communication and visual display devices. LED array display board is a popular
instrument for commercial usage. Many banks, shops and cinemas are willing to install
one piece of it because of its versatility. LED array display board can be very bright
and eye-catching. A display sign used for advertising or for displaying direction or
other information to motorists has an important feature in common. This research
provides an efficient and scalable approach to LED Dot Matrix displays. The system is
comprised of a tricolor dot matrix display panel with an interface circuit to a computer.
It also comprises an executive program that runs on the computer for the display
control of characters, decorative pattern or messages. The display board shows any
character entered from the host computer which is interfaced using USB to a
microcontroller that initializes the led driver. The advantage of this research is that size
of the display board can be increased row wise and column wise without making any
changes in the circuitry since display board is the repetition of a small independent
module.

In this paper, artificial search algorithm(breath algorithm ) are used to design a
symmetric key cryptography system based on DES algorithm,the LFSRs and
breath algorithm are applied to generate a pseudo-random numbers sequence (PNS)
which is used during the encryption process. The quality of PNSs highly depends
on the set of LFSRs rule by selected the polynomial equation cells . This paper
introduces a new method to enhance the performance of the Data Encryption
Standard (DES) Algorithm. This is done by building a new structure for the 16
rounds in the original algorithm. This structure makes use of multiple secrete keys
and the length of key is256-bits to process one block 256-bits of plain text.

This study was designed to evaluate the clinical application of serum total sialic
acid (TSA), total serum protein (TSP) and enzyme activity of alkaline phosphatase
(ALP) and gamma glutamyl transferase (GGT) in serum of 70 subjects. The study
involved four groups, the first group (G1) consisted of 17 normal healthy
individuals , group 2 (G 2) consisted of 20 patients with asthma, group 3 of 15
patients with abdominal bacterial infection , group 4 involved 18 patients with
bone disorders. They were obtained from clinical routine work of different
hospitals of Baghdad, Al-Wasity hospital and laboratory center for allergy of
asthma. The levels of TSA, TSP and the activity of ALP and GGT were
significantly increased in sera of patients with asthma and abdominal bacterial
infection (P< 0.001) as compared with healthy control group. There was a
significant changes observed in TSA, TSP, ALP and GGT in patients with bone
diseases. A significant positive correlation between TSA and ALP was observed in
patients with asthma and a negative correlation with some cases of bone diseases.
A positive correlation between TSA and GGT in patients with asthma and
abdominal infection and some cases of bone disease. In conclusion serum sialic
acid levels might prove to be sensitive but not necessary specific marker of
diagnosis of asthma, abdominal infection and some cases of bone disease

There are three basic encryption methods: hashing, symmetric cryptography,
and asymmetric cryptography. Each of these encryption methods have their own
uses, advantages, and disadvantages. All three of these encryption methods use
cryptography, or the science of scrambling data . Although there can be several
pieces to an encryption process, the two main pieces are the algorithms and the
keys. As stated earlier, algorithms used in computer systems are complex
mathematical formulas that dictate the rules of how the plaintext will be turned into
ciphertext. A key is a string of random bits that will be used by the algorithm.
This paper proposed a method which generates the key that draw from parts of
the image. The size of the key is used with the suggested algorithm to encryption
of the text. This method could be applied to Symmetric cryptography or
Asymmetric cryptography.

In2O3 thin films were grown by the chemical spray pyrolysis (CSP) method
using the pneumatic spray set-up and compressed air as a carrier gas. Aqueous
solutions containing InCl3.4H2O were deposited onto preheated glass sheets at
substrate temperatures Ts=423–573K. X-ray differection (XRD) analysis
confirmed the cubic bixbyite structure of indium oxide. The preferred growth
orientation along the (211) plane for thin films. The crystallite size extracted from
the XRD data corroborates the changes in full width at half maximum due to the
variation in substrate temperature. It was shown that grain size of In2O3 thin film
was (30)nm. Optical properties of In2O3 was studies and showed that the optical
parameters (n, k α) were affected by substrate temperature.
