تتضمن هذه الدراسة قياسات مخبرية باستعمال أوساط، و نماذج مختلفة، لتحديد تأثير الظاهرة الجدارية في قياسات المقاومية الكهربائية إضافة إلى تطبيقات حقلية. درست هذه الظاهرة في حالة وسط متجانس مقاوميته ثابتة، و في حالة وسط غير متجانس مؤلف من طبقتين، و من ثلاث طبقات متباينة. لقد تبين أن تأثير هذه الظاهرة لا يتغير بتباين مقاومية الوسط، أو زيادة عدد الطبقات، بل يتعلق مقدار هذا التأثير بعدة عوامل مثل اتجاه القياس بالنسبة لحافة المنحدر أو الجدار، البعد بين المساري AB مقدار بعد التشكيل عن الجدار.
This study includes laboratory measurements using different models in order to determine the effect of wall-phenomenon on the electrical resistivity measurements, and field applications. This phenomenon had been studied in the case of homogeneous medium of which the resistivity is constant, and in the case of unhomogeneous medium, composed of two or three different layers. It is found that the effect of this phenomenon is the same although the medium resistivity is different or with the increase of the number of layers. This phenomenon changes according to the measurements conditions such as the measurements direction concerning the edge of slope or wall, the distance between AB electrodes, and the distance between the configuration and the wall.

Individuals with dental crowding are the most frequent patients in
the orthodontic clinic. Therefore, it is useful to know the
contributing factors of dental crowding for planning of orthodontic
treatment and achieving stability and retention.
Th

and angular dental Measurements on mandibular anterior
crowding in the early stage of mixed dentition.
Murals are one of the techniques of delineation, which was influenced by Hantine

The Levant was one of the centers of creativity for the
se drawings implemented
in a mosaic and frisco. The drawing are important documents in history,arecord of daily
life and evidence of settlement.to know the properties of the wall paintings, it is necessary
to study the drawings which were implemented in the mosaic and in Frisco. There fore, the
focus was on important bulding that included the drawing in mosaic such as the Dome the
Rock and theUmayyad mosquen and the khirbat al-mfjar palace. And the drawing in frisco
such as Omra palase and palase of western Hier.
The aim of this paper is to present a recent experimental investigation of the wall pressure distribution observed during the emptying of a modeling silo, with and without, inserts, for three different
heights hi of the insert base above the hopper
outlet. The experiments were carried out with corn, at the concrete lab. in faculty of civil engineering in Damascus university in Syria. The results show that the upper-cone with downer-cone trunk insert had a strong influence on the pressures in the silo.
This paper presents an experimental investigation of the flow pattern and wall pressure due to the change of the opening discharge diameter in cylindrical silos. The experiments were performed on a
metal silo prototype using corn as a granular mater
ial. The silo prototype used in the study was built of a metallic cylinder, which can be opened longitudinally allowing the observation of the flow pattern
through a plexi-glass wall, and the wall pressure distribution was measured using a special granular pressure transducer. The present study revealed unexpected results to what might be expected through
current theoretical knowledge.
This work describes our approach for subtasks of SemEval-2021 Task 8: MeasEval: Counts and Measurements which took the official first place in the competition. To solve all subtasks we use multi-task learning in a question-answering-like manner. We a
lso use learnable scalar weights to weight subtasks' contribution to the final loss in multi-task training. We fine-tune LUKE to extract quantity spans and we fine-tune RoBERTa to extract everything related to found quantities, including quantities themselves.
