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>

Relationship between CML and Io's phase according to Jupiter's actual radio storms observations
...Show More Authors

The actual observations for Jupiter radio storm were taken for Hawaii station within multi years from 2001 to 2012. The Central Meridian Longitude (CMLІІІ) and Io's phase (γIo) were calculated for each year from Radio Jove program, the results of CMLІІІ for year 2006 was A=(180-300)º,B=(15-239)º, C=(60-280)º, phase was A=(182-260)º,B=(40-109)º, C=(200-260)º, which were close to the theoretical values, longitude was A=(180-300)º, B=(15-240)º, C=(60-280)º and phase was A=(180-260)º,B=(40-110)º and C=(200-260)º.

Levels of Credibility of the Press within the Structural Model of Credibility
...Show More Authors

There is confusion between the concept of honesty and credibility arguing that their meaning is the same. ‘Credibility; is derived from the truth which means evidence of honesty, while ‘honesty’ means not lying and matching reality. The study of credibility begins globally at the end of the fifties of the second millennium to see the decline and refrain from reading newspapers, while it was studied in the Arab world in 1987. Global studies find several meanings of the concept of ‘credibility’ such as accuracy, completeness, transfer facts, impartiality, balance, justice, objectivity, trust, honesty, respect the freedom of individuals and community, and taking into account the traditions and norms.
Credibility has two dimens

To study the site of placentae and the umbilical artery blood flow of different age groupsand relate that to the newborn baby and the mother. 117 placentae samples were investigatedusing ultrasound and 30 placentae samples were studied using Doppler ultrasound during theperiod from August 2007 to August 2008 for full term placentae of mothers aged 15- > 45 yearsold. By ultrasound; there was detection of good pe rcentage of the placental site to be on theposterior wall of the uterus in case of male babies, while it was anterior in case of female babiesand it was previa and fundal in females more than in the males. The Doppler ultrasound revealedthat the mother in any age group can conceive and have a healthy placenta because the readings ina

Study of the Optical Properties of 3MPA CdTe and 3MPA CdTe/CdSe Quantum Dots at PH 12 in Different Periods of Time
...Show More Authors

This research aims to study the optical characteristics of semiconductor quantum dots (QDs) composed of CdTe and CdTe/CdSe core-shell structures. It utilizes the refluxed method to synthesize these nanoscale particles and aims to comprehend the growth process by monitoring their optical properties over varied periods of time and pH 12. Specifically, the optical evolution of these QDs is evaluated using photoluminescence (PL) and ultraviolet (UV) spectroscopy. For CdTe QDs, a consistent absorbance and peak intensity increase were observed across the spectrum over time. Conversely, CdTe/CdSe QDs displayed distinctive absorbance and peak intensity variations. These disparities might stem from irregularities in forming selenium (Se) layers a
