The adsorption of Cr (VI) from aqueous solution by spent tea leaves (STL) was studied at different initial Cr (VI) concentrations, adsorbent dose, pH and contact time under batch isotherm experiments The adsorption experiments were carried out at 30°C and the effects of the four parameters on chromium uptake to establish a mathematical model description percentage removal of Cr (VI). The
analysis results showed that the experimental data were adequately fitted to second order polynomial model with correlation coefficients for this model was (R2 = 0.9891). The optimum operating parameters of initial Cr (VI) concentrations, adsorbent dose, pH and contact time were 50 mg/l, 0.7625 g, 3 and 100 min, respectively. At these conditions, th

    Two local fish Himri Carasobarbus luteus (Heckel, 1843)  and Hishni Liza abu (Heckel, 1843) were stained with Alizarin Red and featured some anatomical qualities which cleared the difference of the muscular and skeletal fabric for each fish. Since clear Histologic differences appeared in these two species, it was intended from this study the possibility of adopting a diagnosis between local fish species by staining bones and tissues.

خليفة بن خياط بن خليفة الشيباني ألليثي العصفري البصري، أبو عمرو، ويعرف بشَبَابه، الفقيه، المُحدَث، الأديب، المؤرخ، النسَابة، وهو سليل أسرةِ اشتهر أبناؤها بالعلم، وأنجبت عدداً من العلماء الأفاضل، الذين عرفوا في ميادين مختلفة، فالجد والأب والحفيد، علماء محدَثون، وبرزوا في علوم عدة ، كان متقناً وعالماً بأيام الناس.

Among the imams who honor the soil of Iraq by embracing their remains is Imam Al-Qasim Ibn al-Imam Musa Ibn Ja'far ibn Muhammad ibn Ali ibn al-Hussein ibn Ali ibn Ali ibn Abu Talib, Amir of the believers Al-Kadhim (may peace be upon him ), the mother of the sons and the mother of his brother Imam Ali ibn Musa al-Rida (may peace be upon him), buried in the Holy QOM (1)It is one of the doors of need for Shiite Muslims All the stories of imams are similar in terms of injustice
