Abstract

A new, effective, simple and inexpensive method was developed for determination the amounts of Ciprofloxacin HCl in solutions and in tablets by spectrophotometry and turbidity using sodium tungstate as reagent. Also, in this paper comparison between two techniques was conducted. The reaction between the Ciprofloxacin HCl and reagent in acidic media formed a yellowish white complex. Chemical and physical conditions have been investigated. The Linear range for spectroscopic and turbidimetric techniques were (0.05-1.25) and (0.05-3.0) mmol.L-1 with correlation coefficients (0.9956) and (0.9941) respectively. The limits of detection were 7×10-5 and 5×10-5 mol.L-1. The proposed method is good alternative for determination of Ciprofloxacin HCl in tablets.

Abstract

Fertility is a major need for all humans and obesity has been shown an important factor that may affect it. Resistin is one of the adipokines that have a relation with both fertility and obesity. The study aimed to measure the resistin levels in serum and seminal fluid of normal fertile (n=10), obese infertile (n=20) and Non obese infertile (n=10) individuals using the enzyme linked immunoassay method (ELIZA), Also conventional semen analysis was performed for each sample. Results revealed a highly significant increase (p<0.01) in serum resistine levels in normal fertile males (7.4 ng/ml) compared to both non-obese and obese infertile males (1.13, 3.01 ng/ml) respectively the same results for seminal plasma resistin levels (12.1 ng/ml) compared to (2.1, 5.35 ng/ml) respectively. The results give an indication that resistine may have an influence on the fertility of obese males and this need further investigations in the molecular field of research.

Abstract

One-hundred and twenty Iraqi women (60 single women and 60 married women) with age ranges from (17-49) years have been involved in this study to estimate the levels of anti-mullerian hormone (AMH) and follicle stimulating hormone (FSH) as markers of ovarian aging. The descriptive data [age, body mass index (BMI), age at menarche, duration of menarche] have been recorded. Blood samples were collected from the studied women to determine the levels of AMH and FSH. The results revealed non-significant (p>0.05) differences in levels of AMH and FSH between single women and married women. A significant negative correlation was observed between AMH levels and age in single women (r=-0.519, p<0.05) and married women (r=-0.433, p<0.05). A non-significant correlation was found between AMH levels and BMI in single women, while a significantnegative correlation was found in married women (r=-0.311,p<0.05). A non-significant correlation was observed between AMH levels and age of menarche in the two groups, whilea significant negative correlation was observed between AMH levels and duration of menarche in single women (r= -0.520, p<0.05) and married women (r= -0.396, p<0.05). The results showed a significant positive correlation between FSH levels and age in single women (r= 0.525, p<0.05) and married women (r= 0.346, p<0.05),while asignificant positive correlation was found with BMI (r= 0.315, p<0.05) in single women only. Non-significant correlation was found with age at menarche in studied women, whilea significant positive correlation was noticed with duration of menarche in single women (r= 0.529, p>0.05) and married women (r= 0.339, p>0.05). The correlation between AMH and FSH levels in studied women revealed a significant negative correlation in single women (r=-0.429, p<0.05), while a non-significant correlation was found in married women. In single and married women, a significant (p<0.05) decrease was found in AMH levels; while a significant (p<0.05) increase was found in FSH levels in (≥40 years) age category compared with the other age categories. In single women, non-significant (p>0.05) differences were found in AMH levels among the BMI categories,while a significant (p<0.05) decrease was found in FSH levels in (18.5-24.9 kg/m2) BMI category compared with other BMI categories. In married women, non-significant (p>0.05) differences were found in AMH and FSH levels between the BMI categories.In conclusion,this study demonstrated the importance of measurement of AMH and FSH as a good marker of ovarian aging in Iraqi women.

Abstract

In this work, nanostructure porous silicon surface was prepared using electrochemical etching method under different current densities. I have studied the surface morphology and photoluminescence (PL) of three samples prepared at current densities 20, 30 and 40 mA/cm2 at fixed etching time 10 min. The atomic force microscopy (AFM) images of porous silicon showed that the nanocrystalline silicon pillars and voids over the entire surface has irregular and randomly distributed. Photoluminescence study showed that the emission peaks centered at approximately (600 – 612nm) corresponding energies (2.06 – 2.02eV). While current-voltage characteristics shows, as the current density increase the current flow in the forward bias is decreasing, while the rectification ratio and ideality factor varied from one sample to another. Finally, as etching current density increases the built in potential (Vbi) decreases (Vbi= 0.95, 0.75 and 0.55 volt corresponding 20, 30 and 40 mA/cm2) respectively.

Abstract

The magnetic dipole moments and the root mean square radius have been calculated some the Fluorine (A= 17, 19, 20, 21) isotopes based on the sd-shell model using universal sd-shell interaction A (USDA). All studied isotopes are composed of 16O nucleus that is considered as an inert core and the other valence particles are moving over the sd-shell model space within 1d5/2, 2s1/2 and 1d3/2 orbits. The configuration of mixing shell model with limiting number of orbitals in the model space outside the inert core fail to reproduce the measured magnetic dipole moments. Therefore, and for the purpose of enhancing the calculations, the discarded space has been included the core polarization effect through the effective g-factors. The harmonic oscillator potential is used to generate the single particle matrix elements, where the value of the size parameter b is adjusted to get the experimental root mean square of matter radii for each nucleus calculated.

Abstract

In the framework of correlation method so-called coherent density fluctuation model (CDFM) the nucleon momentum distributions (NMD) of the ground state for some even mass nuclei of fp-shell like 50Cr, 52Cr and 54Cr isotopes are examined. Nucleon momentum distributions are expressed in terms of the fluctuation function (|f(x)|2) which is evaluated by means of the nucleon density distributions (NDD) of the nuclei and determined from theory and experiment. The main characteristic feature of the NMD obtained by CDFM is the existence of high-momentum components, for momenta k ≥ 2 fm−1. For completeness, also elastic electron scattering form factors, F(q) are evaluated within the same framework.

Abstract

The application of novel core-shell nanostructure composed of Cu, Ag, Au/NiO to improve the sensitivity of pure NiO to H2S gas sensors is demonstrated in this study. The growth of Cu, Ag, Au/NiO core-shell nanostructure is performed by chemical reaction of NiO on metal nanoparticle (Cu, Ag and Au) that prepared by pulsed laser ablation (PLA( technique. This is to form the homogeneous structure of the sensors investigated in this report to assess their sensitivity in terms of H2S detection. These novel H2S gas sensors were evaluated at operating temperatures of 25 °C, 100 °C and at 150 °C. The result reveals the Cu, Ag, Au/NiO core-shell nanostructure present a good sensitivity at low working temperatures compared by pure NiO nanoparticles. These core-shell nanostructure sensors also possess the highest response (<32 s) and recovery (<28 s) values with greater repeatability seen for H2S sensors at low temperatures, unlike traditional sensors that only work effectively at much higher temperatures. The data in this study indicates the newly-developed Cu, Ag, Au/NiO core-shell nanostructure based sensors are highly promising for industrial applications.

Abstract

An effective two-body density operator for point nucleon system folded with the tenser force correlations ( TC's), is produced and used to derive an explicit form for ground state two-body charge density distributions (2BCDD's) applicable for 19F,22Ne and 26Mg nuclei. It is found that the inclusion of the two-body TC's has the feature of increasing the central part of the 2BCDD's significantly and reducing the tail part of them slightly, i.e. it tends to increase the probability of transferring the protons from the surface of the nucleus towards its centeral region and consequently makes the nucleus to be more rigid than the case when there is no TC's and also leads to decrease the of the nucleus. It is also found that the effect of the TC's and the effect of increasing the values of on the 2BCDD's, elastic electron scattering form factors and are in the same direction for all considered nuclei.

Abstract

The researchers have tried to focus on how to determine the number of pipes that are present in one obtained hyperbola in radargram profile. Ground Penetration Radar (GPR) survey was performed to distinguish between two zero-spaced iron pipes in radargram. The field work was carried out by constructing artificial rectangular models with dimensions of length, width, and depth equal to 10.0, 1.0, 0.65 meter respectively that filled with dry clastic mixture deposit, three twin sets of air filled iron pipes of 15.24 cm (6 inch) diameter were buried horizontally and vertically inside the mixture at different distances together. Visual and Numerical interpretation were chosen to get the best results. In the visual interpretation, the amplitude variations show that the height of the positive peaks increases with the increase of the space distance between the buried pipes. Numerical interpretation appeared that the decrease in the width of the bands means an increase of the space between the pipes. The second part of the numerical analysis comprises measuring the amplitude value variation, among the signal forms; relying on the value of amplitude in each hyperbola the distinction process becomes quite easy. Depending on the variations in amplitude, the identification and discrimination of two closely spaced underground pipes will be feasible. The big values refer to highly spaced pipes while the low values denote the slightly spaced pipes. It is worth mentioning that the lowest value indicates the amplitude of only one buried iron pipe.

Abstract

This study focuses on determining the heterogeneity of Yamama Formation and its spatial distribution in south of Iraq using three indices namely, Coefficient of Variation, Lorenz Coefficient, and Dykstra – Parsons Coefficient. The porosity and permeability values from eleven wells in south of Iraq (Basra and Maysan oil fields) are used for computing heterogeneity indices. Ordinary kriging technique is used to interpolate the computed indices and to show the spatial distribution of these indices over the study area. Results indicated that the average values of Lorenz and Dykstra – Parsons Indices are 0.73 and 0.86, respectively which refer to the extremely heterogeneity nature of Yamama Formation in the study area.The spatial distribution of the heterogeneity indicates that the heterogeneity of Yamama Formation increases from southeast to northeast and follows the same trend of decreasing formation thickness. Results from this study could be helpful in managing production plans in the southern Iraqi fields and enhance oil recovery project.

Abstract

In this paper, the combined source coding with Multi Carrier Code Division Multiple Access (MC-CDMA) system is proposed, where the transmission of the compressed image produced from source coding through Additive White Gaussian Noise (AWGN) channel for a single user and multi users. In which the (MC-CDMA) system removes Inter Symbol Interference (ISI) and Inter Carrier Interference (ICI). The hybrid compression system of Discrete Cosine Transform (DCT) and predictive coding (PC) technique are integrated as a source coding. The simulation results indicates that the transmission system of a single user was much better than the transmission system of multi users. When the number of users increased, the Bit Error Rate (BER) increased. For a single user the BER =8.5×10-7 while the BER=3×10-6 for multi users. Signal to Noise Ratio (SNR) value is used to measure the performance of the MC-CDMA system , when SNR increased thus, BER decreased and preserve image quality and vice versa. Simulation results show that the BER=8×10-2 at SNR=0dB for block size (4×4) and (8×8), when SNR increase the BER decrease as in SNR=10dB the BER=8.5×10-7 for block size (4×4) and BER=4×10-7 for the block size (8×8).

The goal of object tracking is segmenting a region of interest from a video scene and keeping track of its motion and positioning. Track moving objects used in many applications such as video surveillance, robot vision, and traffic monitoring, and animation. In this paper a four-wheeled robotic system have been designed and implemented by using Arduino-Uno microcontroller. Also a useful algorithms have been developed to detect and track objects in real time. The main proposed algorithm based on the kernel based color algorithm and some geometric properties to tracking color object. Robotic system is a compromise of two principal parts which are the hardware and software parts. Hardware includes Bluetooth model to connect the phone with Arduino-Uno. Robot body consists the L298 dual H-bridge motor driver to drive four geared motor, two battery as a power supply and two servomotors to move the camera in both horizontal and vertical axis. Software is responsible for making the right decision based on the analysis of data that receives from the digital camera. Color-based tracking algorithm and border following algorithm used to detect the location of the target object in the images have been showed in the paper. All computations are accomplished within android device. Through applying the object tracking method, several parameters have been considered like frame rate, motor period time and speed of target object. All experiments were in the real environment. The proposed robotic system succeeded to track the target object with a success rate up to 97% in indoor environment.

Abstract

As usage of internet grows in different applications around the world, many techniques were developed to guard an important data against from illegal access and modification from unauthorized users by embedding this data into visual media called host media. Audio hiding in an image is a challenge because of the large size of the audio signal. Some previous methods have been presented to reduce the data of the audio signal before embedding it in the cover image, however, these methods was at the cost of reducing the quality of the audio signal. In this paper, a Slantlet transform (SLT) based method is applied to obtain better performance in terms of audio quality. In addition, the data hiding scheme in the cover color image has been implemented using SLT matrix method. The simulation results prove that the proposed algorithm produce better performance in terms of audio quality and execution time in comparison with the existing DWT based schemes. Also, the proposed data hiding scheme takes good visual quality results and high data hiding capacity.

Abstract

The structural of peculiar spiral galaxy NGC 2608 have been studied using multiband CCD surface photometry of the observations that have been obtained by the 1.88 m optical telescope of Kottamia Astronomical Observatory (Egypt). We studied the structure and radial brightness distribution of the galaxy. The surface brightness distribution indicate that the center of the galaxy consist of two nucleus. The photometric parameters of its components and the color distribution over the galactic are estimated and stellar populations in different regions of the galaxy are analyzed using color diagram. The distributions of the color indices show that the observed photometric symmetry in the inner part of the galaxy, including the bar, is due to a symmetric distribution of absorbing material. The bluest regions of star formation are located in Eastern side of the bar. From the observations, the surface brightness, Ellipticity of the isophotes, Major axes position angle and color indices are discussed.
