This paper presents a methodology to predict reservoir permeability from well logs data by using an artificial intelligence technique namely artificial neural network. A multilayered perceptron trained by backpropagation algorithm was used to build the predictive model. The performance of the net results was measured by correlation coefficient. The implemented artificial neural network model is demonstrated by applying it to Mishrif limestone reservoir at Nasyria oil field, south of Iraq. The results show that artificial neural network was capable of reproducing permeability (horizontal and vertical) with very high accuracy, so that the calculated correlation coefficients for horizontal and vertical permeability were 0.85 and 0.90, respe

Cretaceous stratigraphic water bearing units were evaluated hydrogeologically in combination with hydraulic parameters derived from single (productive) well test. The main recharge of water bearing units comes from percolation of precipitation. Generally all the tested wells taping water bearing units are productive wells and partially penetrating. The transmissivity values obtained by recovery test methods both by INFINITE EXTENT and AQTESOLVE 4.02 software programs reveal as high as double values calculated by constant pumping test methods, particularly for the Balambo aquifer, thus constant pumping test results were employed. While results for the Tanjero Formation are close and similar, therefore both methods were considered in calcu

The inelastic longitudinal electron scattering form factors are calculated for the low-lying excited states of 13C with Jπ T= 3/2- 1/2 (3.684 MeV) and 5/2- 1/2 (7.55 MeV). The two-body interaction of Cohen and Kurath is used to generate the 1p-shell wave functions. The exact value of the center of mass correction which is calculated in the translation invariant shell model (TISM) is included, giving good results. The data are well reproduced when the core polarization effects are included through effective nucleon charge. A higher 2p-shell configuration enhances the form factors for q-values and resolves many discrepancies with the experiments. The results are compared with other theoretical models.

In this work the gelling time of silica alkoxide obtained by sol-gel process has been investigated. The Investigations are made with three variable parameters: water to TEOS molar ratios (1.4, 2, and 10), different pH values and reaction temperatures (25, 40 and 55 ◦C). The study shows that, the reaction temperatures have different effects on the gelling time according to other sol-gel preparation parameters. The values of the activation energy (Ea) were estimated to be approximately the same in the studied range of initial hydrolysis ratio 1.4, 2, 10, slightly varying around 21.2 kJ.mol-1, when the recipes derived under tightly closed cover. While under open recipe and with R-ratio equal to 1.4, Ea rises to 37.2 kJ.mol-1.

Four bacterial isolates Serratia marcescens (S. m.1, S. m.2, S. m3, S. m.4) were tested for their resistance toward ten Antibiotics which consider the most common usage in the hospitals in the country by antibiotic disc method. The isolate S. m.1 was selected according to the antibiotic resistance results since it was resist for several antibiotics and four of these antibiotics were chosen because of the previous researches referred to that these features are carried by plasmid which is Ampicillin, Streptomycin, Tetracyclin and Chloramphenicol and used as a plasmid markers, the DNA of the isolate S. m.1 was contain a plasmid band , the Ascorbic acid used in different concentrations as a curing agent for the bacteria S. marcescens plasmid

Cutaneous Leishmaniasis (CL) is an endemic disease and one of the major
health problems in Iraq. Leishmania major is confirmed as the causative agent of CL
in this region. In Al- Qadessia province alone, the recorded total cases of CL were
618 from 2005-2007. We aimed to determine the effectiveness of a polymerase
chain reaction (PCR) technique for identification and differentiation of the
Leishmania parasite in clinical samples. The lesion exudates were collected from 27
suspected patients (12 males and 15 females) and used for smear slide preparations,
culture on NNN medium then DNA isolation. The isolated DNA was amplified by
PCR, including primers selected on repetitive kDNA for identification

Diabetes mellitus is one of the common health problems. It has many serious
complications among them are hypertension and diabetic nephropathy which may
lead to renal failure. The first sign of early stage renal of failure or diabetic
nephropathy is proteinuria which {presence of an abnormal amount of protein in
urine} which leads to hypertension. As its known that hypertensive patients need
treatment and those with diabetes and proteinuria need more attention to be given
during choosing their antihypertensive medications by using effective drugs with
less side effects and comply with many aspects that are looked for by both the
physician and the patient. This study was conducted on {28} diabetic p

The present work adapts the lambda cold dark matter ΛCDM model for simulating 106 dark matter and 106 gas particles to form galaxies inside a box of size (70Mpc/h)3. The simulation is shown from high redshift z=10(1.2Gyr.) after the Big Bang to the low redshift z=0(13.4Gyr.) which represents the present day. The position of the particles and the temperature-density relations were studied at each epoch. It is found that the galaxies formation start at low redshift z=5 and the gas cooled at 104 K. The web construction of voids, filaments and clusters of galaxies were observed clearly at z=0. Sixteen processors of high performance supercomputer of Nottingham University-England were used in the simulation and the run took more than one day.

This paper proposes a method for automatic adaptation of segmentation control parameters based on Genetic Algorithms. The goals of automatic adaptation of segmentation parameters in this research are to provide continuous adaptation to normal environmental variation conditions such as (time of day, weather) to exhibit learning capability and to provide robust performance when interacting with a dynamic environment. The research intended to adapt the performance of a well known existing segmentation method (Recursive region growing Algorithms) across a wide variety of environmental conditions which cause changes in the image characteristics and maximizes the segmentation quality measures. Experimental results are given that indicate the a

Digital image inpainting is a technique that can repair a portion of damaged or removed image by means of automatic mechanisms.
This paper proposes an automatic approach for reconstruction of small missing or damaged portions of images using Particle Swarm Optimization (PSO). The PSO inpainting approach attempts to find the best match between Red, Green, and Blue (RGB) channels of the pixels masked (i.e. pixels of the region to be removed) and pixels in the surrounding area, and transfer the color of the best matching. The results show that our mechanism is more efficient (i.e. less time required to inpaint the masked region) when compared with genetic - based image inpainting.

The preequilibrium statistical model, which is used to analyze nuclear reaction data, depends basically on number of parameters including the master equation. A numerical solution for the master equation of the preequilibrium statistical model is presented in this work. One-component Fermi gas model is assumed. This numerical method is shown to give the same accuracy for the simple as well as the more advanced schemes. The present method shows fast convergence for a wide range of physical system parameters. Such a method is applied for two reaction examples that include neutron and proton induced reactions with 54Fe nucleus for entrance energies 20 and 80 MeV. Comparisons with standard solution methods show that the method suggested here

A rapid and sensitive spectrophotometric method is proposed for the determination of metoclopramide hydrochloride. This method is based on the diazotization reaction of metoclopramide hydrochloride with sodium nitrite in hydrochloric acid medium; the formed diazonium salt is then coupled with phenol in sodium hydroxide medium, to form a yellow water-soluble mono azo dye. Beer’s law is obeyed in the concentration range of 1 – 20 μg mL-1 at 463 nm with detection limit 0.406 μg mL-1.
