إن عسل النحل الطبيعي في الآونة الأخيرة أصبح ذو أهمية بالغة، فازدادت حاجاتنا له كطعام ذو قيمة غذائية عالية، وكعلاج بالغ التأثير والفائدة. ونتيجة لذلك تهدف الدراسة الى تقدير بعض الخواص الفيزيائية والكيميائية كقاعدة لتحديد الجودة الشاملة للعسل، حيث تم جمع ست عينات من منتوج عسل النحل من السوق المحلي في مدينة الخمس (عسل السدر، عسل الربيعي، عسل الأثل، عسل السرول، عسل الزعتر). ولقد أجريت لهذه العينات بعض القياسات وذلك لمعرفة مدى جودة العسل ومقارنة نتائجها بالمواصفات الليبية والعالمية حيث تراوحت قيم الرقم الهيدروجيني (3.51-4.59) pH والتوصيلية الكهربائية �.

Predicting using the climate scenario for model CIMP6 the Seasonal Changes for carbon dioxide on the air temperature over Tripoli city from 2015-2050

Haifa M. Ben Miloud
The Libyan city of Tripoli is home to many residents. Therefore, when using the CIMP6 climate models for the SSP 245 scenario that is appropriate and close to the current climate for the periods 2015-2019, 2020-2039, and 2040-2050, for both air temperature and carbon dioxide, that gas increases seasonally. Carbon dioxide in winter reaches 499.51PPM until the year 2050, as well as the increase in air temperature shown in its anomalies, which reaches 1.49 C0. Note that the increase in carbon dioxide gas is natural in winter becomes free in the air compared to summer, which is distinguished by the rise in temperature. Which causes air stagnation of pollutants, as well as the increase in human activity, which is shown in the two-dimensional correlation between air temperature and carbon dioxide. It increases in the summer and reaches 0.560 and 0.567 for the periods 2015-2019 and 2040-2050, respectively, and increases in the south of the city more than north of it due to its views of the se.

This study is concerned with the effect of electromagnetic radiation (ERM) emitted from the mobile phone due to its frequent use on a daily basis and for long hours and understanding the damage it may cause. other live when exposed to these rays for long periods. In this research, the effect of (ERM) emitted from mobile phones at a frequency of 900-1800MHz on the embryonic formation of local chickens was studied, where 90 samples were collected to compare eggs exposed to electromagnetic radiation and those not exposed to electromagnetic radiation. This study concluded that there are effects of (ERM) emitted from mobile phones at a frequency of 900-1800 MHz on fetuses exposed to electromagnetic radiation compared to healthy fetuses (not exposed to radiation) represented in the small size of the head, bleeding under the skin and in the nose, the appearance of a hernia in the abdomen, and a transparent layer on the eyes as well as the wings and legs with a weak structure, the b.
