تؤثر السمات التشريحية و اللونية للسن في طبيعة الإشارة المستقبلة فيأثناء قياس الأكسجة اللبية، و تعد سماكة الأنسجة المينائية من أهم المؤثرات. لذلك؛ أجري هذا البحث السريري بهدف تقييم تأثير سماكة الأنسجة المينائية في الأسنان الحية السليمة في دقة قراءات الأكسجة اللبية. تشير نتائج هذه الدراسة إلى وجود تأثير واضح لسماكة الأنسجة السنية في دقة قياس الأكسجة اللبية، لذلك؛ لابد من إيجاد التعديل المناسب على أجهزة القياس أو حساساتها أو برمجتها بطريقة ما، بهدف تقليل تأثير الاختلافات التشريحية بين الأسنان، و زيادة دقة القياس.
Anatomical features and color characteristics of teeth may affect the recipient signals' nature during dental pulp oximetry, enamel tissue thickness may consider of the most important factors. This clinical study aimd to evaluate the effect of enamel tissue thickness of the upper premolar crown on the accuracy of dental pulp oxygen saturation readings. The results of this study indicate that there is a considerable effect of the dental tissue thickness on the dental pulp oxygenation measurement. So; it is of important to find the suitable adjustments on the PO apparatus, probe, or programs, in order to gain less effect of the anatomical variances between teeth, and thus increasing pulse oximetry measurement accuracy.

Many factors affect dental pulp pulse oximetry technique (PO), as recipient
signals may reflect not only pulpal blood flow, but also may mixed with signals of blood flow of the
periodontal or gingival tissues. To evaluate the effect of isolation of
the periodontal tissues apart from the
dental crown using rubber dam; during pulpal blood oxygenation of the deciduous molars.
Hypoxemia is defined as the condition of insufficient oxygen saturation of the blood. Hypoxemia considered as one of most dangerous problem encountered pulmonologists cardiologists and critical care nursing, it complicate the ICU stay of many childre
n every year with significant associated mortality, it causes more than two million deaths worldwide in children less than five years of age. The study aimed to identify the best pulse oximetry placement among three placements (thumb, big toe, and ear-lobe). The study was conducted in the department of intensive care, and incubators, in Obstetric and Pediatric Hospital, and Al-Assad Hospital in Lattakia city, the sample consisted of 70 children. The results revealed that both the thumb and toe sites has an equal sensitivity in detection of hypoxemia.
The article aims to study the effect of layer thickness and reflection coefficient variation on the image of synthetic seismogram, which is generated by using Ricker Wavelet with wide range of frequencies (20-130Hz) and Vibrator Sweeps with many freq
uencies ranges (5-170Hz) as a known technique in reflection seismic method on land. The Researcher tried to
determine the relationship between signals recording times and reflection coefficients variation from first side, and recording times with layer thickness variation from second side. The result which is observed that; the recorded times increased proportionally with increasing of the layer thickness (as we
know), but it is delayed with exponential relation when the velocity and density are varied within the same layer. New manner is applied to represent the result by using the conversion of time seismic section to raster images by using GIS,
this way gave us ability to control the colored scale which reflects the amplitude of recorded signals, and follows the reflectors or get important information about signals amplitude even though the layer thickness is decreased less than wavelet length ten times if we used Ricker signal or Vibration Sweeps.
Therefore in this paper we will present the stability analysis carried out on the
Dwesat dam with vertical core, its high is 33m, the downstream slope of 1V:2.75H and the
upstream slope of 1V:3.0H. Thickness of the vertical core was varied from 1V:
0.25H to
1V:2.0H, and also present the effect of the varied thickness on slope stability for both
upstream and downstream under three design conditions i.e. during and end of
construction, steady state seepage and rapid draw down by General Limit Equilibrium
Method using GeoStudio software.
It was observed from the analysis that by varying the thickness of vertical core of
earth dam, thinner core up to 1V:1.30H gives more stability and further increase in
thickness of core tends to sharp decline in factor of safety for both upstream and
downstream slope under different design conditions.
The purpose of this study was to evaluate the histological effects
after the miniscrew penetration into dental root on dental pulp and
cementum during orthodontic treatment.
