Journal of Basrah Researches (Sciences), Volume 37, Issue 2, Pages 26-34

The coast and the seabed of North-West Arabian Gulf marine water have a uniquehydrodynamic and sedimentary environment,due toits morphological shapeand the hydrological effects of shatt Al Arab –karun river system and Shatt Al Basrah –khor Al-Zubair chanal ,besides other khors nearby the study area .All these variabls are considered as acontributing factorsin sediment yield of the study area.
A high dust fallout contribution in the area and sand bars extension along the longtituinal axis of khor Abddullah lead to wide variations in sediment grain size distribution from silty clay to sandy mud textures.These phenomena conferming high hydrodynamic activities in the study area. Clay minerals identification indicates that the occurence of illite mineral is due to rapid sedimentation processes ,and a kolinite mineral origin is from eaolian source.

This study was conducted to isolate and identify the molds and yeasts associated with Thelah fish Scomberoides commersonianus (Forskal,1775) which dried in laboratory using solar dryer and compared with sun dried fish which obtained from the local market in Basrah during 6 months storage periods at laboratory temperature (25±2)˚C from Jan.2007 to May 2008. The effects of temperature and pH on the molds were also studied. The following finding were obtained : Nine species of molds were isolated from dried Thelah fish, eight of them related to the genus Aspergillus except one species which related to the genus Penicillium .There were significant differences at (P>0.05) for means logarithmic numbers of molds in dried Thelah fish . A.niger had given the highest mean for logarithmic numbers of molds. Three types of yeasts were isolated and identified as: Candida albicans , C. catenuiata and Rhodotorulla sp. The first one gave the highest mean. From the other hand the number of molds and yeasts in the samples directly dried by sun light were found to be more than the solar dryer samples within the progress of storage periods up to 6 months. The study also showed that the means of radial growth of molds increased with increasing of temperature degrees up to 35 ˚C , while they decreased with increasing of pH values up to 4.5. The statically analysis results revealed significant differences (P>0.05) among the means of molds radial growth at all tested temperature degrees and pH values.

Journal of Basrah Researches (Sciences), Volume 37, Issue 2, Pages 104-117

This paper presented a hybrid method consisting of three intelligent systems (artificial neural networks, fuzzy logic, genetic algorithms), since these systems are effective in solving different issues but all the system suffers from some problems that reduce efficiency, so it was to integrate these systems with some To give the system benefit from the advantages of each method and encroaches on the disadvantages.
We used in this research method of a hybrid resulting from a combination of fuzzy logic and neural networks, as used fuzzy logic to fuzzified training data and weights used in the neural network, and this method is called fuzzified neural networks, which gives the network a greater ability to generalize and accelerate the convergence process, but this method suffers of a problem in determining the number of fuzzy sets and optimal fuzzy weights, as the experiment method used to select it. To resolve this problem, genetic algorithm was used to determine the best number of fuzzy sets and the best fuzzy weights through research, which makes the network more efficiently trained.
