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 properties 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.

Critical review
دراسة نقدية: تقدم الورقة البحثية معلومات قيمة حول استخدام الموجات فوق الصوتية في قياس تدفق الدم، ولكنها تفتقر إلى بعض التفاصيل العملية التي قد تكون مفيدة للباحثين والممارسين في المجال. على سبيل المثال، لم يتم التطرق بشكل كافٍ إلى التحديات التي قد تواجه التطبيق العملي لهذه التقنية في بيئات مختلفة. كما أن الورقة تعتمد بشكل كبير على المعادلات الرياضية دون تقديم تفسير كافٍ للقراء غير المتخصصين. كان من الأفضل تضمين أمثلة تطبيقية وحالات دراسية لتوضيح الفوائد والتحديات بشكل أفضل.

This paper proposes a new approach for the segmentation of the retina images to obtain the optic nerve and blood vessels regions. We used retinal images from DRIVE and STARE databases which include different situations like illumination variations, d ifferent optic nerve positions (left, right and center). Illumination problem has been solved by preprocessing stage including image histogram-based illumination correction. Next, some morphological operations were used to filter the preprocessed image to obtain the ROI region, then, the center and radius of optic nerve were determined, and the optic nerve region was extracted from the original image. In blood vessels segmentation, we applied the illumination correction and median filtering.Then the closing, subtraction and morphological operations were done to get the blood vessels image which was thresholded and thinned to get the final blood vessels image.
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 primar y 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 reseated is to estimate cerebral blood flow in the cerebral microvasculature beds by measuring the change of the intensity gray scale levels in dynamic angiographic images which have been acquired by Digital Subtraction Angiography (DSA).
Blood groups are of greatclinical importancein blood transfusion and in tissue transplantation. In fact,the discovery ofthe ABOsystemwas oneof the most importantfactors in making the practice ofblood transfusion possible.The person`sABO bloodtypeis usedin paternity suits,in forensic science andin thestudy ofdifferent populations. To provide accurate anddocumented information about the frequency ofABO and Rh Dblood groups in oursocietyand to identifythe frequency of the most important otherblood systems :Rh, K, Duffy, Kidd.
In this research, the concentration of thiocyanate ion in serum has been investigated, thiocyanate has negative effects on human body when it increasses higher than specific limit, this ion is produced by the metabolism of cyanide which exist in ci garette smoke. Spectrophotometric method has been used in the visible range at λ=460 nm, the formation of the complex between thiocyanate and reagent Ferric chloride (FeCl3) have been made in an ideal parameters such as temperature 25 ºC, time=15 min, pH=4.4, volume of citrate buffer=0.75 ml, volume of reagent (FeCl3) =1 ml and concentration of reagent = 0.02 mg/ml. The selected method showed good accuracy and precision, the accuracy of the method has been validated with R=99.3%, and the precision of relative standard deviation was (RSD<=1.149 % . The concentration of thiocyanate has been studied in a sample of 240 non-smokers’ and in a sample of 240 smokers’, these samples have been divided into different age groups. The maximum concentration of thiocyanate was 89.49 μmol/L in the fourth group (>50 years) of the non-smokers’, and the maximum concentration of thiocyanate was 190.27 μmol/L in the fourth group (>50 years) of the smokers’. The maximum concentration of thiocyanate was 91.647 μmol/L in the non-smokers’ males and 86.623 μmol/L for the nonsmokers’ females, whereas the concentration of thiocyanate was 204.53 μmol/L in the male smokers’ and 167.33 μmol/L in the female smokers’.
