TSK model was the interested model that the researchers focused on because of the flexibility of
this model in real problems , Although TSK model has main disadvantage : depends -at the beginningon
random parameters that may distribute the convergence of the solution.
In this paper, We discuss the disadvantages of TSK model; and try to cover it by a new proposed
TSK rule base model that merges fuzzy sets properties and the nonlinear function in the rule. This
means that rule output will depend not just on the random parameters, but on the outputs centers in
every rule too. We used the proposed model to simulate pendulum real problem plant, and the
experiment results showed increasing accuracy and decreasing training time in comparison with the
traditional TSK rule base model.

The study deals with the depositional environments and biofacies of sediment north Basrah where
the southern marshland (Ahwar).Grain size analysis indicates to three types of sediment texture are; mud
,silt ,and sandy silt. The size parameter indicates to manifold environment. The specified foraminifera
species in the present study determine two biofacies; B1 is a brackish estuarine environment graded up to
fluvial condition, and B2 is a brackish-marine to marine environment. The species of foraminifera
distincted the marine influence in the study area.

In this paper, a modified discrete wavelet transform method with a hierarchical adaptation to
the signal size is developed to enhance wavelet-compression performance: reduction of the bit rate,
enhancing the quality of reconstruction, and the reduction of computational complexity. The method
is based on adaptive padding alignment wavelet-coefficients to an approximation coefficient
sequence of a certain wavelet-decomposition level for forming an even length sequence. The
presence or absence of the alignment wavelet-coefficients is determined by the binary values of the
alignment vector components. A comparative efficiency evaluation, of the methods of onedimensional
and two-dimensional rational (or integer) wavelet-transform with and without a
hierarchical adaptation to the image size, is presented. It is found that the developed method provides
a gain in terms of compression coefficients, peak signal-to-noise ratio and computational complexity.

This study investigated the acute toxicity of Endosulfan, a polycyclic organochlorine pesticide, to
the tropical shrimp Caridina babaulti basrensis. C. babaulti basrensis specimens were collected from
Garmmat Ali-River at 30°34'16'' N 47°44'59''E during April, 2006. The 24h, 48h, 72h and 96-h LC50s
values for shrimp were estimated as (0.010, 0.006, 0.003 and0.002) mg/l., respectively. Safe
concentration level for endosulfan was 0.02 μg L-1
