 إنّ دراسة الأحاديث النبوية ومعرفة مدى صحتها من عدمه أمرٌ في غاية الأهمية لبناء الأحكام الشرعية عليه، وقد صنّف الأئمة وجمعوا الحديث وتنوعت أساليبهم، ويعتبر الإمام البيهقي من المتأخرين الذين صنّفوا في الأحاديث، ومنها كتابه السنن الكبرى، فقد أطلق على جملة من الأحاديث لفظة (إن ثبت) ويعلق الحكم الشرعي على ثبوت الحديث، من غير بيان درجة وحال الحديث وأقوال الأئمة فيه بشكل قطعي لتمييزه، فأخذت بجمع تلك الأحاديث ال

الأنبياء الصغار هم (اثنا عشر) نبيًا كُتبت لهم أسفار قصيرة في العهد القديم. سُمّوا صغارًا لقصر أسفارهم، لا لقلة أهميتهم. عاشوا بين القرن التاسع والخامس قبل الميلاد. خدم بعضهم في مملكة إسرائيل (الشمالية) قبل سقوطها سنة 722ق.م. وآخرون في مملكة يهوذا (الجنوبية) قبل سقوطها سنة 586ق.م. عاش اليهود ثلاث مراحل مهمة في تاريخهم، وهي: قبل السّبي، وأثناء السّبي البابلي (605- 586) ق، م. وبعد السّبي (538) ق.م. تنبأ بعضهم بعد العودة من السّ

   CO₂-based acidizing provides a corrosion-resistant alternative to potent mineral acids in carbonate reservoirs by producing carbonic acid in situ. This method synchronizes stimulation procedures with carbon-management objectives while minimizing the necessity for comprehensive corrosion-inhibitor systems. This review assesses six categories of chemical additives—amines, inorganic salts, inorganic bases, metal-oxide nanoparticles, biological macromolecules, and natural biopolymers—emphasizing their effects on CO₂ absorption, pH buffering, and wormhole morphology at reservoir-relevant temperatures and salinities. Experimental findings indicate that specific formulations can achieve CO₂ absorption levels reaching

A scalable method of oxalate co-precipitation was used to prepare magnesium oxide (MgO) nanoparticles. The precipitant used was oxalic acid and the source of soluble magnesium was magnesium sulfate.  Highly crystalline MgO nanoparticles prepared by calcining at 700  were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Atomic Force Microcopy Analysis (AFM). The (MgO) nanoparticles were employed to investigate the adsorption performance of Methyl Violet (MV) dye from aqueous solutions under different conditions, i.e., contact time, pH, dye concentration and temperature.  Maximum adsorption (96%) was obtained at time (60 min.), pH 6, at (20  ) and adsorbent dosage (0.05 g

   This work aims to study the kinetics of heterogeneous electro-Fenton (HEF) process used to treat petroleum refinery wastewater by a catalyst made of an activated carbon loaded with iron and cerium. Effects of HEF operating variables such as current density, dose of catalyst, and pH on the removal of COD and reaction rate constant (k_app) were examined. Results showed that decline of COD with time at different operating conditions obeys a pseudo-first-order kinetics with a regression fitting (R²) not less than 0.97. Furthermore, increasing the current density was found to give higher rate of COD removal and k_app to a limit beyond which no longer enhancement can be achieved. Similar behaviour regarding

   It is challenging to remove antibiotics from water bodies, as they are among the most widespread contaminants in the environment, particularly with conventional wastewater treatment methods, due to their persistence and low biodegradability. The current study examined the use of nanoscale zero-valent iron to remove antibiotics. Conocarpus leaf extract, which is primarily composed of polyphenols like flavonoids and tannins, was employed as a green source to prepare Fe/Cu nanoparticles, which can act as an eco-friendly reducing agent. The nanoparticles were immobilized onto silica sand (SS), forming SS-Fe/Cu nanocomposite to remove tetracycline (TC) and ciprofloxacin (CIP) from aqueous solutions. The structural characteristics of th

The structural behavior of Segmental Precast Post-tensioned Reinforced Concrete (SPPRC) beams largely depends on the behavior of the joints that connect between the segments. In this research, series of static tests were carried out to investigate the behavior of full-scale SPPRC beams with different types of epoxy-glued joint configurations; multi-key joint, single key, and plain key joint. The reference specimen was monolithically casted beam and the other specimens were segmental beams with five segments for each one. The general theme from the experimental results reflects an approximate similarity in the behavior of the four beams with slight differences. Due to the high tensile strength of the used epoxy in comparison to concr

Joints are among the most widespread geologic structures as they are found in most each exposure of rock. They differ greatly in appearance, dimensions, and arrangement, besides they occur in quite different tectonic environments. This study is important because joints provide evidence on what kind of stress produced them (history of deformation) and also because they change the characteristics of the rocks in which they occur. The Measured data of joints from the studied area which are located in the high folded zone – Northeast of Iraq, were classified according to their relationship with the tectonic axes by projecting them stereographically using Schmidt net in GEOrient ver.9.5.0 software. The joint systems revealed the orientation of

         The present paper sheds light on irony as one of the most important and most common linguistic phenomena in modern linguistics, in general ,and in discourse in particular, whether it is (political, literary, journalistic, etc.). When irony is used correctly or positively, it paves the way for the speaker to gain the approval of other parties participating in the dialogue and dissolve barriers between them. It is a simple multi-functional linguistic style and an expression of one’s meaning by using language that normally signifies the opposite according to the context and the situation. Therefore, it is necessary to study its characteristics, define its functions and traces the extent of
