يهدف البحث إلى تمثيل الجريان الدموي في شرايين الطرف العلوي عند الإنـسان، و ذلـك بإيجاد مخطط سرعة تدفق الدم اعتماداً على معادلات الديناميك الدموي، تم وضـع نمـوذج بسيط لأهم الشرايين معتمدين على الدراسة التشريحية للطرف العلوي، حـددت المعلومـات الأولية مثل (القطر، و الطول، و السرعة) لكل شريان من خلال جهاز دوبلر و ذلـك لـشخص ذكر، سليم يتمتع بالمواصفات الآتية : وزنه 64Kg ، و عمره 40 سـنة، و معـدل النـبض 62bpm و تتراوح قيم أقطار الشرايين عنده مابين mm 6.2-6.1.
The objective of this study was to model the Blood Flow into human arm’s arteries in order to define velocity profile. All steps were based on computational fluid dynamics .Simplified model for arm’s most important arteries were made, while primary data such as length, diameter, and velocity were collected for a healthy 40 years old, male , weight 64 Kg with pulse rate 62 bpm ,and his arteries ranges from 1.6 to 2.6 mm by using Doppler measurement.Bio dynami

The purpose of this research is to detect, locate, and define the blood vessels
in the arm of any person who has a problem in taking samples of blood for
laboratory testing in order to make it easier, not dangerous nor harmful.
Depending on the pr
operties of the scattering wave from the blood and the
depth of the penetration, we have calculated the frequency which is
necessary to choose the suitable transducer including the Geometric
Dimension as well as the materials which is made from (we have taken the
5MHz Doppler –CW for 1.2 cm depth, 2.37 attenuation ratio and the 8MHz
Doppler –CW for 0.74 cm depth , with the same attenuation ratio).
Depending on the velocity's variation of the blood flow throughout the
Biodynamic studies for important arteries in the upper limb, we have found
the Doppler frequency which occurs when the acoustic wave passes across
the blood red cell. We have designed a suitable electronic instrument which
includes the transmitter circuit, receiver circuit, and the output unit - Audio
graph.
This paper presents an experimental investigation of the flow pattern and wall pressure due to the change of the opening discharge diameter in cylindrical silos. The experiments were performed on a
metal silo prototype using corn as a granular mater
ial. The silo prototype used in the study was built of a metallic cylinder, which can be opened longitudinally allowing the observation of the flow pattern
through a plexi-glass wall, and the wall pressure distribution was measured using a special granular pressure transducer. The present study revealed unexpected results to what might be expected through
current theoretical knowledge.
The oil reservoirs exploitation processes are one of very important
steps of petroleum industry. The rentability of investor reservoir is
related to correct planning and accurate understanding of rock
properties and liquids flow in porous media. T
he complexity of
porous media contains hydrocarbon materials, with phases changes related to thermo-physiochemical phenomena, make the classical methods used to study the reservoir recovery are inaccurate and insufficient to predict the performance and behavior of reservoir.
Recently, simulation and modeling are used to decrease the risks in the decision of the optimal recovery method, and achieve the best possible rentability. This method provides predictive capacity help us to better understanding of reservoir. By the suitable input data, we can solve the calibrated mathematical model analytically or numerically. We present in this research the formulation of
mathematical model of isotropic-one dimension reservoir with
single phase fluid flow. The numerical solution, the application of
this model, and the mechanism of pressure diffusivity along
productive formation, will be presented to simulate a reservoir with injection and production wells.
Palliative procedures in TOF patients with
small-caliber pulmonary arteries aim at alleviating cyanosis and improving
the overall clinical condition, as well as progressively enlarging the small
pulmonary arteries, a step preceding the total surgi
cal correction of TOF.
The present study compares between two types of palliative procedures, i.e.
Modified Blalock’s vs. Open Brock’s.
Studies have proven that the indicatingpressure chart of marine engine cylinder can providemany information not only about pressure, but also about a large number of parameters that are useful in enhancing engine performance. Therefore, in this resea
rch paper, we attempt to study the indicators that complete the physical image of the work cycle. This attempt uses an elaborate and comprehensive mathematical model for obtaining and using these parameters in order to form a clear image of the work cycle based on the dynamics of heat release in the cylinder, for the purposes of enhancing performance and achieving a more efficient, more economical mechanical operation. As a result we will reach a number of conclusions and recommendations which,upon being approved and used, can help to achieve with great mathematical accuracy a more optimized characteristic of the work cycle.
