The photo-electrochemical etching (PECE) method has been utilized to create pSi samples on n-type silicon wafers (Si). Using the etching time 12 and 22 min while maintaining the other parameters 10 mA/cm2 current density and HF acid at 75% concentration.. The capacitance and resistance variation were studied as the temperature increased and decreased for prepared samples at frequencies 10 and 20 kHz. Using scanning electron microscopy (SEM), the bore width, depth, and porosity % were validated. The formation of porous silicon was confirmed by x-ray diffraction (XRD) patterns, the crystal size was decreased, and photoluminescence (PL) spectra revealed that the emission peaks were centered at 2q of 28.5619° and 28.7644° for etching time 12 and 22 min, respectively. Studying the capacitance and resistivity during temperature increasing and decreasing for both itching times shows clearly that the prepared pSi as a thermal sensor is working better and in more selectivity for 20 min itching time
The concept of poetics has different dimensions, part of which is related to the creative achievement, and part is related to the critical perspective.
Among the commentators who contributed greatly to explaining the basic rules of civilizations in general and Islamic civilization in particular, Sheikh Muhammad Rashid Rida in his interpretation called (Interpretation of the Wise Qur’an), known as (Al-Manar); Whoever reads the tafsir will notice that it was concerned with explaining the civilized aspects in terms of foundations, methodology, factors of demolition and destruction, and ways to avoid them.
This research attempts to study Monetary system status and financing in the CIB through 4 sections, starting with the methodology and ending with conclusions and recommendations.
These two topics of Monetary and financing, that falls within the mandate of the CBI, are researched / studied relying on the resources and relevant literature. This research is a simple contribution, but meantime it is an honest attempt to elevate the effective role of the CBI which is considered one of the most pioneering central banks in the region.

accompanied the development process in iraq and is now pointing in the
depth of institutional struetues and threaten the sociol fabric and cohesion
mechamisms .
The study included of the most importana social problems that
accompamied thecrises and occupation in iraq as aproblem of unemployment
aworce, forced displacement and disintegration of family and juvenile
delinguency and the problems of drug addiction .
The study relied on sample slected from the city of Baghdad ,showed
the most important results of that two-thirds of the asssets of an urban sample
compared to one third of them from rural aelcyrounds and that there is
