Application of Finite Element Technique: A Review Study
...Show More Authors

The finite element approach is used to solve a variety of difficulties, including well bore stability, fluid flow production and injection wells, mechanical issues and others. Geomechanics is a term that includes a number of important aspects in the petroleum industry, such as studying the changes that can be occur in oil reservoirs and geological structures, and providing a picture of oil well stability during drilling. The current review study concerned about the advancements in the application of the finite element method (FEM) in the geomechanical field over a course of century.

Firstly, the study presented the early advancements of this method by development the structural framework of stress, make numerical computer solution

Surface Plasmon Resonance study of Ag nanoparticles colloidal
...Show More Authors

Silver nanoparticles (Ag-NPs) have been prepared using the electro-chemical
method. The experimental setup of this technique consist of two electrodes of pure
silver (99.2 %), the applied voltage on the electrodes is 20 V and the current through
the colloidal was about 0.4 Amp. The silver nanoparticles crystallization has been
studied; the crystalline structure appears Face center Cubic. The optical properties of
silver nanoparticles are strongly affected by the Local Surface Plasmon Resonance
(LSPR). The wavelength of maximum absorption band for an Ag NPs have a range
(~350nm-550nm).

Administrative Collection of State Debt : A comparative study
...Show More Authors

           The state's finances consist of a set of rights that have a material value. Since the debtor's failure to pay is conceivable, it is reasonable to assume that the State is in constant need of funds to manage its various activities. The state, but what distinguishes it from others in this case is its ability to fulfill the will of the individual without the need to resort to the judiciary to collect the debt.

Histological Study of Stomach in (Mallard) Anas platyrhynchos
...Show More Authors

This search aim to study the histological structure of Stomach of domestic duck Anas platyrhynchos. Six healthy birds (males and females) are used and after their slaughter the abdominal region was carefully opened and the stomach separated from it's connection with alimentary canal, cleaned with water and fixed  in 10% formalin. The histological study showed that the wall of the glandular and muscular stomach consist of four tunicae:Tunica Mucosa,Tunica Submucosa,Tunica Muscularis and Tunica Serosa. The results suggested that the Muscularis mucosa layer represented the secretary part of glandular stomach, the keratinoid material lining the lumen of gizzard, and the tunica muscularis was the thickest one among four tunicae. &nb

Study of Dynamic Sorption in Adsorption Refrigeration Cycle
...Show More Authors

This paper shows the characteristics of temperature and adsorbed (water vapor) mass rate distribution in the adsorber unit which is the key part to any adsorption refrigeration system. The temperature profiles of adsorption/desorption phases (Dynamic Sorption) are measured experimentally under the operating conditions of 90oC hot water temperature, 30oC cooling water temperature, 35oC adsorption temperature and cycle time of 40 min. Based on the temperature profiles, The mass transfer equations for the annulus adsorbent bed are solved to obtain the distribution of adsorption velocity and adsorbate concentration using non-equilibrium
model. The relation between the adsorption velocity with time is investigated during the process of ads

Electrophysiologic Study of Cognitive Functions in Epileptic Patients
...Show More Authors

Background: Cognitive dysfunctions in epileptic patients may develop due to the neurophysiologic changes related to seizures or antiepileptic drugs.
Objectives: The aim of this longitudinal study was to evaluate the cognitive dysfunction in epileptic patients under antiepileptic drug therapy by the aid of event related potentials.
Patients & Method: P300 latencies were obtained from Fz, Cz and Pz electrodes positions from both epileptic patients (n = 224) and age and sex matched control group (n = 91). Epileptic patients were classified either having partial epilepsy, generalized epilepsy or both partial and generalized epilepsy (combined epilepsy). EEG and p300 test repeated for each patient every three months for one year. Th
