Helicobacter pylori (H. pylori) is widespread and involved in the pathogenesis of the majority of stomach and duodenal diseases. Reduced stomach acidity facilitates the initial infection. Electrolytes (sodium, potassium, and chloride) are essential for the production of stomach acid. This study aimed to observe any changes in the levels of serum electrolytes (Na, K, and Cl) and serum vitamin C levels in a sample of Iraqi patients infected with H. Pylori. We studied 30 infected patients with H. Pylori and 30 matched healthy controls. The results revealed that the serum sodium, potassium, and chloride levels were significantly decreased (p = 0.002, 0.003 and 0.0001, respectivel

     This paper focuses on choosing a spatial mixture model with implicitly includes the time to represent the relative risks of COVID-19 pandemic using an appropriate model selection criterion. For this purpose, a more recent criterion so-called the widely Akaike information criterion (WAIC) is used which we believe that its use so limitedly in the context of relative risk modelling. In addition, a graphical method is adopted that is based on a spatial-temporal predictive posterior distribution to select the best model yielding the best predictive accuracy. By applying this model selection criterion, we seek to identify the levels of relative risk, which implicitly represents the determination of the number of the model components o

     Let R be a commutative ring with 1 and M be a left unitary R-module. In this paper, we give a generalization for the notions of compressible (retractable) Modules. We study s-essentially compressible (s-essentially retractable). We give some of their advantages, properties, characterizations and examples. We also study the relation between s-essentially compressible   (s-essentially retractable modules) and some classes of modules.

To assess various methods for relocating a fictional satellite from a geosynchronous transfer orbit (GTO) to a lunar orbit, this research project was conducted. The primary objective of the study was to determine the most time and cost-effective technique, while also considering the influence of perturbations and other possible variables on orbital mechanics analysis. Three different approaches were examined, involving the transfer of the satellite in one, two, or three separate rounds. The development of algorithms for this investigation relied on MATLAB orbital mechanics software, and careful consideration was given to factors such as delta-v, mission duration, spacecraft mass, and potential perturbations throughout the course of the t

Let U be a Lie ideal of a 2-torsion free prime ring R and θ ,φ be commuting
endomorphisms of R . In this paper we generalize the main result of M. Ashraf, A.
Khan and C. Heatinger on (θ ,φ ) -higher derivation of prime ring R to generalized
(θ ,φ ) -higher derivation of Lie ideal by introducing the concept of generalized (θ ,φ )
-higher derivation. Under some conditions we prove that a Jordan generalized (θ ,φ ) -
higher derivation of U is either a generalized (θ ,φ ) -higher derivation of U or
U ⊆ Z(R) and every Jordan generalized (θ ,θ ) -higher derivation of R is a
generalized (θ ,θ ) -higher derivation of R . Also, we generalize this result to
generalized (U,R) − (θ ,θ ) -higher derivatio

In the present work, the different possible interactions between comet tail and the solar wind in the present of the inter-planetary magnetic field (IMF) had been studied. Magneto-hydrodynamic laws (MHD) were used to simulate interactions occurring between comet tail and solar wind using one –dimensional space. The model simulation was achieved using Lax-Wendroff explicit method. The interaction between cometary tail ions and solar wind can be understood by means of spatial distribution of new-generated ions from the comet nucleus with the homogenous flow of the solar wind plasma. The difference between average molecular mass of both types along with step-increase in the number of particles can reproduce the whole shape of the comet ta

This study aimed to test the effect of using different concentrations of three different plants extracts to inhibit the growth of gram negative and gram positive bacteria by two technics. Eucalyptus camaldulensis bark, Glycyrrhiza glabra rhizomes and Morus nigra leaves ethanolic extract at (0,20,30,40 and 50 mg/ml) were used.

After the mentioned periods, blood samples from each animal were taken for blood analysis. Then, the mice of all groups were sacrificed and the livers were removed, pro

The PCA is statistical technique that transforms a multivariate data set consisting of inter-correlated variables into a data set consisting of variables that are uncorrelated linear combination. In our project principal component analysis “PCA” was applied for two set of original bands in two dates (bands 1, 5, and 7 in 1988 and bands 1, 5, and 7 in 1990).
In this method the PCA of six channel data sets consisting of multi-temporal LANDSAT TM image pairs often generates higher order principal components that are related to the changes in brightness.
Although the image produced by the first component summarizes the information’s
that are common to all channels, we can see that the first principal component is

The data compression is a very important process in order to reduce the size of a large data to be stored or transported, parametric curves such that Bezier curve is a suitable method to return gradual change and mutability of this data. Ridghelet transform solve the problems in the wavelet transform and it can compress the image well but when it uses with Bezier curve, the equality of compressed image become very well. In this paper, a new compression method is proposed by using Bezier curve with Ridgelet transform on RGB images. The results showed that the proposed method present good performance in both subjective and objective experiments. When the PSNR values equal to (34.2365, 33.4323 and 33.0987), they were increased in the propos

The present paper deals with estimation of compaction parameters from the empirical relationships relating time and velocity of the propagated sonic waves with depth. For this aim two geologic intervals were chosen at Jambur area, the first one is limited between the top of Fatha formation (M. Miocene) and base of Jeribe formation (L. Miocene) while the second one is limited between the base of Jeribe formation and the top of Qamchuqa formation (Albian – M. Cretaceous). Sonic logs data revealed the existence of two Low Velocity Layers (LVL) in these intervals. They correspond to porous saliferous and seepage beds in the first interval. and to the highly fractured and oil bearing carbonate bed in the second interval.

A digital elevation model (DEM) is a digital representation of ground surface
topography or terrain. It can be represented as a raster (a grid of squares) and it is
commonly estimated by utilizing remote sensing techniques, or from land surveying.
In this research a 3D building of Baghdad university campus have been performed
using DEM, where the easting, northing, and elevation of 400 locations have been
obtained by field survey using global positioning system (GPS). The image of the
investigated area has been extracted from QuickBird satellite sensor (with spatial
resolution of 0.6 m). This image has been geo-referenced by selecting ground
control points of the GPS. The rectification is running, using 1st order

Extracting moving object from video sequence is one of the most important steps
in the video-based analysis. Background subtraction is the most commonly used
moving object detection methods in video, in which the extracted object will be
feed to a higher-level process ( i.e. object localization, object tracking ).
The main requirement of background subtraction method is to construct a
stationary background model and then to compare every new coming frame with it
in order to detect the moving object.
Relied on the supposition that the background occurs with the higher appearance
frequency, a proposed background reconstruction algorithm has been presented
based on pixel intensity classification ( PIC ) approach.

The present study includes the evaluation of petrophysical properties and lithological examination in two wells of Asmari Formation in Abu Ghirab oil field (AG-32 and AG-36), Missan governorate, southeastern Iraq.

The present study was conducted using 15 adult male Swiss albino mice (weighing 35-45g). They were equally divided into three experimental groups. The first group was only given water as control during experimentation period (28days). Both of the second and third groups of mice were daily given a subcutaneous injection of cadmium as cadmium chloride (CdCl2) at a dose of 2mg and 4 mg Cd/Kg body weight respectively. The examination of the histological sections of the second experimental group of mice showed abundant histological changes in the hepatocytes such as increased size, presence of spaces and dense appearance of the cytoplasm, whereas these changes were more abundant in the hepatocytes of the third experimental group of mice in co

The research involves examining the influence of partial solar eclipse on the strength of neutral hydrogen from the Sun. Baghdad University Radio Telescope (BURT) was used to monitor the partial solar eclipse on the 25^th of October, 2022. Radio observations from the Sun were recorded from 11:30 AM to 03:36 PM. This means that the HI emission from the Sun was recorded before, during and after the event. It was noticed, that at the moment of maximum eclipse, ~ 46% of the Sun’s disk was covered by the Moon. For the purpose of this research, the solar radio wave intensity was monitored and the solar flux density was determined at different times, i.e. before, during and after the partial solar eclipse. The obtained results showe

Dust storms are a common ecological occurrence in many world‘s countries, mainly in dry and semi-dry parts. Dust storms tremendously influence human health, the environment, the climate, and numerous social aspects. In this paper, spatial and temporal analysis, metrological triggers, and trajectory, dust exporting areas of a severe dust storm that occurred in Iraq on May 16, 2022, were investigated. The dust storm's backward trajectory was determined using HYSPLIT model, which is then compared with MODIS and Meteosat satellite images. The weather is then analyzed using the NCEP/NCAR Reanalysis model, and the approximate area of these sources was determined using Landsat 8 satellite image classification method. The results revealed that

This study aims to investigate the features of stellar-gaseous kinematics and dynamics mass using scaling coefficient relationships (such as the Faber–Jackson relation (FJR)) of two samples of elliptical and lenticular galaxies. These two samples of 80 ellipticals and 97 lenticulars were selected from previous literature works. The Statistical Package for Social Sciences )SPSS( and Matrix Laboratory (MATLAB) program were used to find out the associations of multiple factors under investigation such as main kinematic properties of the gaseous-stellar (effective radius Re, surface density within the effective radius (Ʃeff) , stellar mass in the blue band (Mstar (B)), gas mass ( Mgas), dynamic (Mdyn) and baryonic (Mbar), supermassive bla

The accretion circumstellar disk of young stars and the Brown dwarf plays an essential role in the formation and evaluation of the planet. Our main work in this paper is to investigate the geometrical shape model for the protoplanetary disk around one of the Brown Dwarfs. The photometric measurements for the brown dwarf CFHT-BD-Tau 4 were extracted from the Vizier archive. We used a numerical simulation to build a model of the spectral energy distribution of our target CFHT-BD-Tau 4. The spectral energy distribution model was fitted with observational data for the brown dwarf CFHT-BD-Tau 4. A transitional disk has been assumed around CFHT-BD-Tau 4. We obtained physical properties of the two disks and the size of the gap between them by f

In this work, the impact of different geomagnetic storm events on the plasma-sphere layer (ionosphere layer) over the northern and southern hemisphere regions was investigated during solar cycle 23. To grasp the influence of geomagnetic storms on the behavior and variation of the critical frequency parameter of the F2 ionospheric layer (f_oF2), five geomagnetic storms (classified as great, severe, and strong), with Disturbance storm time (Dst) values <-100 nT were chosen. Four stations located in different mid-latitude regions in northern and southern hemispheres were designated, the northern stations are: Millstone Hill (42.6° N, 288.50° W) and Rome (41.90° N, 12.50° E) and the southern stations are: Port Stanley (-51.6

In this paper, a consideration is given to viscose, incompressible and Newtonian fluid flowing in a pipe with square cross-section under the action of pressure gradient. In particular consideration is given to first order fluid flow which can be represented by the equation of state of the form:
Tij = 2η eij , i,j = 1,2
Where η is constant of fluid, Tij and eij are the stress and rate of strain respectively. Cartesian coordinate has been used to describe the fluid motion and it found that motion equations are controlled by Reynolds number. The motion equations are solved by a semi-implicit algorithm namely Semi-Implicit Method for Pressure Linked Equations (SIMPLE).

A fingerprint verification technique is presented. The Principal Component
Transformation “PCT” is used to identify a checked person, by comparing its
