The Relationship Between the Above-Ground Biomass and the Vegetation Cover Indices at Different Salinity Levels
...Show More Authors
Abstract<p>The current study was carried out to find out the relationship between the Above-Ground Biomass and the spectral vegetative indices (Normalized Difference Vegetation Index, Soil Adjusted Vegetation Index, Difference Vegetation Index) (NDVI, SAVI, DVI) for soils with different salinity levels. Al Salamiyat Project was chosen as a study area located at an altitude of 34 m above sea level and within the geographical coordinates (E 44°.09´13.65´´ N 33°.25´ 07.87´´ and E 44°.17´ 46.03´´ N 33°.2l´40.72´´), with a total area of 14265 Dunum. Surface and subsurface soil samples were chosen from the study area and according to the previously defined salinity units, except for the salinity map that was updated based on the soil samples of the current study. After updating the salinity map of this project, 12 Pedons (two Pedon for each salinity unit) were excavated and morphologically described. Then, the soil samples were taken from each horizon to estimate the physical and chemical properties and biomass values for each site. The study showed that the soil salinity Ece in the study Pedon ranged from 1.1 dS/m in the C2 horizon for the twelfth Pedon to 41.6 dS/m in the upper Az horizon of the ninth Pedon. It also showed that there is a high correlation (r = 0.553) between the values of soil salinity and the biomass of plants growing in it, which confirms that the biomass was increasing with the increase in soil salinity. Furthermore, the (NDVI) showed a variation in the study area, ranging from 0.386 to 0.473, while the values of this index ranged from 0.1568 to 0.4093, as it was observed that there is a direct relationship between them (r = 0.643). The values of (SAVI) showed a difference between the studied Pedon sites, the values of this index ranged from 0.0581 to 0.7100, and it was also ranged from 0.1087 to 0.6213 for the same Pedon value. Whereas the values of the (DVI) index ranged between -0.0023 to 0.0942 and from 0.0197 to 0.0874 for the study Pedon, this index showed a highly significant relationship with the above-ground biomass (r = 0.825).</p>

Employment and Labor Union Laws in Japan between the 1889 and 1946 Constitutions: A Comparative Study: أفراح محمد علي
...Show More Authors

This research is based on the descriptive and analytical methodology. The importance of studying labor laws and labor unions in Japan between 1889 and 1946 constitutions is because Japan was out of a feudal phase, and had no idea about the factory system and industrialization in their modern sense before the Meiji era. Generally, its labor system used to be mostly familial, and the economic system was based on agriculture. This called for the enactment of legislations and laws appropriate for the coming phase in Meiji era. Thus, this paper examines the role of Meiji government in enacting labor legislations and laws when he came to power in 1896, and his new constitution in 1889 and the civil code of 1896. It further examines the way Mei

A Comparative Study Between the Fragile and Robust Watermarking Techniques and Proposing New Fragile Watermarking with Embedded Value Technique
...Show More Authors

Since the Internet has been more widely used and more people have access to multimedia content, copyright hacking, and piracy have risen. By the use of watermarking techniques, security, asset protection, and authentication have all been made possible. In this paper, a comparison between fragile and robust watermarking techniques has been presented to benefit them in recent studies to increase the level of security of critical media. A new technique has been suggested when adding an embedded value (129) to each pixel of the cover image and representing it as a key to thwart the attacker, increase security, rise imperceptibility, and make the system faster in detecting the tamper from unauthorized users. Using the two watermarking ty

Pharyngeal airway volume and its relationship to the facial morphology in nasal breathing and mouth breathing subjects (A comparative computerized tomography study)
...Show More Authors

Background: The value of lateral cephalometric radiographs to evaluate the pharyngeal airway is limited because it provided 2-dimensional (2D) images of complex 3-dimensional (3D) anatomic structures. Three dimensional analyses of the airway volumes are required to understand oral and pharyngeal adaptations in mouth breathing and nasal breathing subjects. The aim of this study was to measure the pharyngeal airway volume and the size of the face, then compare between pharyngeal airway volume in mouth breathing and nasal breathing subjects and find the gender difference in each group, also to study the relation between pharyngeal airway volume and the size of the face. Material and Methods: Fifty patients including 28 males and 22 females wit
