The Effect of Salinity Levels of irrigation water and Mechanical Damage of Seeds on the Germination and Growth Characteristics of Seedlings of Two Varieties of Bread Wheat ) Triticum aestivum L.(

"A factorial experiment with completely randomized design (CRD)with three replicates was carried out at agronomy laboratory of the Directorate of seed testing and certification / Branch of Salahaldeen to study the effect of salinity levels of irrigation water )0 ،1.75 and 2 Mm ) and grains affected by the use of mechanical seeds in seed germination and seedling growth for two varieties of wheat bread(IPA99 and Sham 6). The characteristics of germination percentage ،speed germination ،length of plumule and radical ،pure live seed percentage and seed vigor studied. The observed results are as follows: Significant differences are found between cultivars. (IPA99) cultivar gave the highest tolerance to water salinity and seed fracture. However ،salinity levels and seed fracture caused a significant decrease in all features. As for interactions ،cultivars and seed mechanical damage interactions were significant in all characteristics. While the interactions of varieties and levels of salinity were significant in the characteristics of the speed of germination and length of plumule . Interactions of salinity levels and seed mechanical damage did not reach the significant limit except for the characteristic of the plumule’s length, which reached the highest value at 7.697 cm . At the same time, the triple interactions (cultivars ،seed mechanical damage and levels of salinity) were significant except for both germination percentage and pure live seed percentage. The best triple interaction was (IPA99) with 1.75 Mm and undamaged seed, which gave the best values in: germination percentage ،length of plumule and radical ،pure live seed percentage and seed vigor. The values of the above were as follows: 98.67% ،8.707 cm ،10.01 cm ،94.72 ،18.45 respectively."

Penggunaan Metode Pembelajaran Inovatif dan Hubungannya dengan Kemampuan Mengoptimalkan Gaya Belajar Siswa

This study aims to determine the effect of Innovative learning methods on learning styles in Aqidah Akhlak lessons for eighth grade students of MTs Darul Arafah Pangkalan Berandan. This research method uses quantitative data analyzed using descriptive statistics and inferential statistics. Innovative learning is learning that provides more opportunities for students to construct knowledge independently and mediated by peers. Based on the results of research and data analysis, it can be concluded that the Innovative learning method at MTs Darul Arafah Pangkalan Berandan has an average result of 36.33, a median of 36.5, a mode of 37, a variance of 24.95 and a standard deviation of 4.99. acceptable with a significant limit of tolerance. Learning Styles of students at MTs Darul Arafah Pangkalan Berandan have an average result of 47.9, a median of 48.5, a mode of 47.6, a variance of 9.40 and a standard deviation of 3.06. acceptable with a significant limit of tolerance. There is a significant effect between Innovative learning methods in improving the learning styles of students at MTs Darul Arafah Pangkalan Andan with the results Fcount = 31.15 and Ftable (1.28) (0.01) = 7.56 which can be concluded Fcount≥Ftable by accepting Ha and rejecting H0 with a regression line equation of (Y= ) 45.57+0.06X.

Modeling of Detector Radiations Response P-I-N in Technology Thin Film on ASIC (TFA) Intended for Digitalization in Medical Imagery

In this work, the study of detector radiations response p-i-n modeling in technology Thin Film on ASIC (TFA) is reported. It has been revealed that for some nanoseconds time formation of preamplifier, the charge induced by the electrons is entirely collected. Nevertheless, a part of the charge created by the holes is integrated, due to the slow transport of this latter, which constitutes a significant limit for detection speeds.

Schmidt hammer tests across a recently deglacierized rocky coastal zone in Spitsbergen - is there a "coastal amplification" of rock weathering in polar climates?

Schmidt hammer tests across a recently deglacierized rocky coastal zone in Spitsbergen - is there a "coastal amplification" of rock weathering in polar climates? A significant limit to current understanding of cold coast evolution is the paucity of field observations regarding development of rocky coastlines and, in particular, lack of precise recognition of mechanisms controlling rock coast geomorphology in polar climates. Results are presented from a pilot survey of rock resistance using Schmidt Hammer Rock Tests (SHRT) across the recently deglacierized Nordenskioldbreen forefield and coastal zone, in central Spitsbergen, Svalbard. The aim is to improve understanding of the effects of rock weathering on high latitude coasts. SHRT across a field of roches moutonnées of meta-morphic rocks, uncovered from ice over the last century and exposed to the operation of littoral processes, demonstrated significant relationships between rock surface resistance and distance from present shoreline, distance from the ice cliff as well as thickness of the snow cover. Sites closest to the present-day shoreline were characterized by lower resistance in comparison with more inland locations. The result support models that advocate intensification of weathering processes in cold region coastal settings.
