New chelating ligand derived from triazole and its complexes with metal ions Rhodium, Platinum and Gold were synthesized. Through a copper (I)-catalyzed click reaction, the ligand produced 1,3-dipolar cycloaddition between 2,6-bis((prop-2-yn-1-yloxy) methyl) pyridine and 1-azidododecane. All structures of these new compounds were rigorously characterized in the solid state using spectroscopic techniques like: ¹HNMR, ¹³CNMR, Uv-Vis, FTIR, metal and elemental analyses, magnetic susceptibility and conductivity measurements at room temperature, it was found that the ligand acts as a penta and tetradentate chelate through N₃O₂, N₂O₂, and the geometry of the new complex

The design of coordination compounds with solvent-responsive optical properties remains a central challenge in molecular photonics. Here, we describe the synthesis and full characterisation of a symmetrical tetradentate diamine ligand, 3,3′-((1,2-phenylenebis(azanediyl))- bis(methanylylidene))bis(pentane-2,4-dione) (H₂L), and its neutral square-planar complexes [M(L)] (M(II) = Co, Ni, Cu). The Cu(II) complex crystallised as [Cu(L)]⋅0.5 (pyrazine), adopting a nearly square-planar geometry (τ₄ = 0.06) in the solid state, as confirmed by single-crystal X-ray diffraction. In DMSO solution, UV–Vis spectra revealed reversible axial coordination of two solvent molecules, driving a transformation to a distorted octahedral geometry. Struc

Assessing the accuracy of classification algorithms is paramount as it provides insights into reliability and effectiveness in solving real-world problems. Accuracy examination is essential in any remote sensing-based classification practice, given that classification maps consistently include misclassified pixels and classification misconceptions. In this study, two imaginary satellites for Duhok province, Iraq, were captured at regular intervals, and the photos were analyzed using spatial analysis tools to provide supervised classifications. Some processes were conducted to enhance the categorization, like smoothing. The classification results indicate that Duhok province is divided into four classes: vegetation cover, buildings,

White and black chia seeds were used in some food products, such us gluten –free biscuits processing by using rice flour and chia seeds (white and black) with these amonths 112.5, 74.25, 56.25, 27.5 g with 27.5g of quinoa seeds for treatments 1, 2, 3 and 4 respectively, and comparison sensitively with the control treatment which has no additions including the appearance and homogenization of the product, surface cracks, softness, taste and flavor, core color and the specific volume, some microbiological tests were performed for biscuit product after storage for 4 months at 30 and 50°C including bacterial total count and fungal and yeast count, results showed that there weren’t any observation of bacteria or yeast or fungal growth at

يختلف دور العلاقات العامة (PR) وأهميتها من مجتمع إلى آخر، تبعاً لاختلاف ثقافات هذه المجتمعات عموماً, ولاختلاف القيم الأخلاقية المعمول بها من ممارسيها في منظمات هذه المجتمعات, فالعلاقات العامة في المجتمعات المتقدمة وبعض الدول النامية قد خطت خطوات جبارة ووصلت إلى مرحلة المساهمة في التخطيط الاستراتيجي وعملية اتخاذ القرار, في إطار التزام إداراتها بقيم ومعايير أخلاقية محددة لممارسيها, وبالمقابل نجد أن تطبيقها في

Prayer It is the second pillar of Islam, which is what Allaah erases sins, the Prophet, peace be upon him say: "Do you see if the river at the door of you wash it every day five, what it says: it keeps dirt," they said, does not keep the dirt something, He said: «That is like the five daily prayers, Allaah erases sins", Bukhari (1/112), and the places and times supervised thanks to worship them, was to pray at the three mosques (the Grand Mosque and the Prophet's Mosque and the Al-Aqsa Mosque) private virtue from the rest of the mosques and this virtue include the obligatory prayers and Voluntary Prayers.
