This study, which is considered the first of its kind in the world and the Arab homeland, was carried out in the laboratory of mushroom production belonging to the Medicinal Plant Unit/ College Of Agricultural Engineering Sciences/ University of Baghdad during the period from July 21, 2016, to December 30, 2018, aiming to isolate and purify the mycelium of the wild isolation in addition to the genetic and morphological identification of the mushroom Agaricus bellaniae. The obtained pure isolation was tagged in the American National Center for Biotechnology Information (NCBI) with symbol MF987843.1, thus Iraq would be the second country in the world in which the mushroom is grown following the United States of America. The optimum temperature for the mycelium growth rate was also determined in the laboratory, as they ranged between 50 -60 ◦C. Furthermore, the dried fruit bodies were recognized qualitatively and quantitatively to identify their content of medicinally active compounds. Theyhave shown a high percentage of Linoleic acid (47.77%), total anti-oxidants, and total phenols in addition to the high content of essential chemicals including high protein percentage (44%), mineral elements- selenium in particular (0.369 ppm), and amino acid where glutamic and aspartic acids recorded the highest percentage, reached 4.02% and 2.226% respectively.
تعد شريحة المعلمين والمدرسين من أهم الشرائح في المجتمع لما لها من أهمية ودور كبيرين في إعداد الأجيال إلى مراحل دراسية الجامعية والأعمال والمهام التي يتطلبها منهم المجتمع في المستقبل ، لذا سعت الدوائر والمؤسسات التربوية للاطلاع والوقوف على المعيقات التي يمكن أن تؤثر على هذه الشريحة من حيث الإعداد أو الحجم أو التخصص أو الخبرات من اجل رفد العملية التربوية والمؤسسات التربوية بكل الإمكاني

Show MoreWhat we observe from the weakness of the students in some of different subjects may be due to that students are learning these traditional methods and competing to acquire the mark, and attain their teachers' interest ,then their only aim becomes the academicsuccess, and this is whatcontradicts the modern educational philosophy.
Education needs to be providing it with new ideas and methodologies toprepare an emerging demonstrated scientific reason to distance them from the tradition and indoctrination that do not create generations able to address theexpected problems.

Brown (1980) considers that it is conscious and reflective controlcarried out by the individual in his actions and cognitive responses through the use of self-regulation skills (planning, monitoring and evaluation).
The search problem raises through following question: Havestudents ofhigh school for distinct metacognition?

exchanger dynamics during flow reduction transient in their secondary loops. Finite difference
mathematical model was prepared to cover the heat transfer mechanism between the hot water in the
primary circuit and the cold water in the secondary circuit during transient course. This model takes under
consideration the effect of water heat up in the secondary circuit due to step reduction of its flow on the
physical and thermal properties linked to the parameters that are used for calculation of heat transfer
coefficients on both sides of their tubes. Computer program was prepared for calculation purposes which

Crystallite size of the nanocrystalline films are determining from broading of X-ray diffraction lines and are found to vary from 0.33-0.52 nm, an increase of molarity the grain size decreases which turns increases the band gap. The band gap of nanocrystalline material is determined from the UV spectrograph. The absorption edge and absorption coefficient increases when the molarity increases and shifted towards the lower wavelength.
Background: Fracture of different types of acrylic denture base is a common problem associated with dental prosthesis. Studies suggested that the repair strength may be improved by several means including surface treatment with chemical agents. The aim of the study was to evaluate the effect of surface treatment with acrybond-bonding agent and monomer on fractured denture base in respect to transverse, tensile and shear bond strength and evaluation of the mode of failure by light microscope. Materials and methods: Two hundred seventy specimens were prepared and divided into 3 groups according to the material used (regular conventional, rapid simplified and high impact) heat cure acrylic. The specimen in each groups were prepared specificall
