شهد العالم في السنوات الماضية قفزة نوعية في مجال العلوم الفيزيائية الطبية و لاسيما ما يتعلق بتطبيقات الليزر في الحالات المرضية المختلفة حتى أصبح أداة لا يمكن الاستغناء عنها من قبل بعض الاختصاصات مثل التجميل و الجراحة. لكل نوع ليزر هناك نسيج أو عدة أنسجة يؤثر فيها بشكل نوعي دون سواها، و يؤدي هذا التأثير إلى إنتاج حرارة عالية في النسيج المعالج، و هذه الحرارة هي التي تظهر الخواص العلاجية لليزر، لذلك فإن الاستعمال الأمثل لأجهزة الليزر يجب أن يكون بعد فهم التفاعل المتبادل بين الليزر و النسيج الحيوي و فهم العوامل الفيزيائية المؤثرة في العلاج التي لها الأثر الكبير في الأثر الحراري و من ثم يمكن التحكم من تقليل الأذية الحرارية غير المرغوب فيها.
Recently laser applications have been expanding to include many fields. Among these, are medical laser surgery and biological applications. It is important to understand the interaction mechanisms that may occur when applying laser light to biological tissues in order to minimize damage to the tissues resulting from extra heat applied. The aim of this study is to study the temperature distribution in living biological tissues when laser irradiation is used in a treatment by solving bio-heat equation.

This research discusses the affecting factors of biogas production
in the digester, to define the optimal temperature and suitable
loading rate to achieve high digester biogas production. The
research focuses on the water compressed continuous flo
w
digester (chines model), and the results is presented and illustrated
in suitable tables and curves.
This research aims to introduce a new effective method to analyze and
solve thin slabs that are exposed to heat flux in full over one surface,
whereas the other surface is exposed to heat exchange with the
surrounding.
A new equation was introduc
ed by the author in order to find heat
distribution against the depth of the slab. The new equation is based on
Lablace equations with consideration to heat exchange with the
surrounds. It was found out that when heat exchange reaches zero
(insulated), then the new equation is conformed to other equations in
different references.
Consequently, the coefficient of linear expansion of slab material (α) was
put to function at temperature α(T). Therefore, the deflections of
circular and rectangular simple support slabs were found. Hence, and
according to this, bending moment, shear force and torsional moments
could be found for these slabs.
Effect of organic and bio fertilizers (Azotobacter and phosphate solubilizing
bacteria) on production of potatoes and some soil properties was studied in
Tartous.
The experiment consisted of 4 treatments (control soil, soil+manure, soil+
bioferti
lizer and soil+manure+biofertilizer) each replicated four time, for 2004
and 2005 seasons.
Total N, available P, available K, and organic matter in soil were
determined.
Significant increases were observed in most of the inoculated and organic
fertilized treatments compared with the control. However, the treatment
(soil+manure+biofertilizer) was the best and showed significant increases in
potato yield compared with other treatments especially in the next season.
However, the second season was better in yield increase in all treatments
than the first seacon.
It is very important to the design and development of
natural isolating materials Which are used in the cover-up of solid waste landfill, clay soils or mixtures of these soils and some
additions used as an impermeable liner for construction of soli
d
waste landfill, The permeability coefficient of the materials used in the impermeable system is the most important factors to prevent water leakage into the body of landfill site and to prevent the Leachate of leak into groundwater and soil surrounding the landfillsites.
In this research has been the development and design
Oedometer cell to study volumetric distortions occurring in these
soils as a result of exposure of these soils to climatic conditions
during the implementation of impermeable layer or after
implementation due to rising temperatures in landfill because of
biological interactions taking place at these landfill.
It has been modified and the development of Oedometer
cell to become a thermal cell So that it can control the degree of
heat applied to the sample in the ring of device and then measure the volumetric changes in the sample, Oedometer cell has been linked to the permeability test system with variable head to measure the permeability of the testing sample, It was connected with the digital control , measuring and showing system for temperature and load and displacement.
This research was conducted during the growing season of 2015 at
AL-Arema village of governorate Tartus, to study the effect of
three spray bio-fertilizer times (1- flowering stage. 2- pods
formation stage . 3- seeds formation stage), and four rat
es of biofertilizer
(zero, 2 cm3/liter ,4 cm3/liter,6 cm3/liter) in the growth and
productivity of peanut crop.
The experiment was designed by using Split-plot design three
replications.
