The laboratory experiment was conducted in the laboratories of the Musayyib Bridge Company for Molecular Analyzes in the year 2021-2022 to study the molecular analysis of the inbreed lines and their hybrids F1 to estimate the genetic variation at the level of DNA shown by the selected pure inbreed lines and the resulting hybrids F1 of the flowering gene. Five pure inbreed lines of maize were selected (ZA17WR) Late, ZM74, Late, ZM19, Early ZM49WZ (Zi17WZ, Late, ZM49W3E) and their resulting hybrids, according to the study objective, from fifteen different inbreed lines with flowering time. The five inbreed lines were planted for four seasons (spring and fall 2019) and (spring and fall 2020) in the spring season 2019 the inbreed lines were crossed and flowering time were recorded and in the fall season 2019 they were crossed according to the study objective (late × late), (late × early) and (early) × late) and (early × early) in the third season, The results indicated that the two initiators used with the target flowering gene are highly efficient in diagnosing genetic variations and genetic divergence between the selected inbreed lines and their resulting hybrids F1 according to the different flowering time using PCR Poly Chain Reaction and Gel electrophoresis techniques. ) and the fourth hybrid (early×early) was superior in most of its field traits. It was found that inbreed line No. 15 (ZA17WR) did not show any bands in the interaction of the PCR and the flowering gene, and this is evidence that this inbreed line is counted as being optimal for the target gene and therefore genes or genetic sites may influence the early or delayed flowering time trait Therefore, it needs future studies. The aim of the current study is to know the genetic structures that contain the flowering gene and according to the planting date, whether fall or spring, to take advantage of those results in choosing and determining the appropriate and most appropriate method in the maize crop breeding programs to obtain promising genetic structures in terms of flowering time, whether was early or late. Additionally using two techniques to gather leads to increase the usefulness of these two techniques as the number of examined hybrids and inbred lines continues to increase rapidly.
The Vulnerable Indian Roofed Turtle Pangshura tecta (Gray, 1831) (Testudines: Geoemydidae) occurs in the Sub-Himalayan lowlands of India, Nepal, Bangladesh, and Pakistan. Little is known about its natural history, no studies have been conducted revealing its natural predators. In this study, a group of Large-billed Crow Corvus macrorhynchos Wagler, 1827 (Passeriformes: Corvidae) was observed hunting and predating on an Indian Roofed Turtle carcass in the bank of river Kuakhai, Bhubaneswar, India. The first record of this predation behaviour is reported and substantiated by photographic evidence.
Abstract
The aim of the current research is to identify the level of availability of written expression skills included in the Arabic language curriculum document among middle school students from the teachers' point of view. The researcher used the descriptive approach. To analyze the data and access the research results, he used the (SPSS) program. The research was conducted during the first semester of the academic year 1442/1443 AH on a random sample of Arabic language teachers in the Bisha Education Department. They reached about (213) male and female teachers. The results revealed a number of indicators: the level of availability of written expression skills among middle school students in Bisha governorate

The focus of this research: is the study of poetic text in the pre-Islamic era and the era of early Islam. The research followed a method in treating poetic texts, as it is based on presenting poetic texts from the collection of Al-Abbas bin Mardas, explaining the features of his poetic vision, and examining all the external factors that surrounded the poet and influenced his vision and all his thoughts. The results of this research was that Al-Abbas Ibn Mardas revealed some of the positions that he found contradicted the authentic Arab value before the advent of Islam, and the poet Abbas bin Mardas tr

One of the most suitable materials to be used in latent heat thermal energy storage system (LHTES) are Phase change materials, but a problem of slow melting and solidification processes made many researchers focusing on how to improve their thermal properties. This experimental work concerned with the enhancing of thermal conductivity of phase change material. The enhancing method was by the addition of copper Lessing rings in phase change material (paraffin wax). The effect of diameter for the used rings was studied by using two different diameters (0.5 cm and 1cm). Also, three volumetric percentages of rings addition (3%, 6% and 10%) were tested for each diameter. The discharging process was done with
