The present study include micofacies analysis of Khurmala Formation(U.Paleocene – L. Eocene), Dokan Area,
northeastern Iraq.The Formation units is divided to five main microfacies which divided to (11) Sub- microfacies
(Dolomitized Lime Mudstone, Bioclastic Lime Mudstone, Bioclastic Lime Wackestone, Algal Lime
Wackestone, Miliolid Lime Wackestone, Algal Miliolidal Lime Packestone, Algal Lime Packestone, Miliolid
Lime Grainstone,Algal Miliolid Lime Grainstone, Peloidal Lime Grainstone, Boundstone microfacies) . The
micofacies indicated that the Formation has deposited in a semi_ restricted quiet Lagoon , reef mound and
tidal flat (intertidal).

Geochemical analysis, mineralogical, petrographic and petrophysical studies were carried on samples of
limestone rocks have been collected from four selected outcrops on the eastern side of Makhul anticline, between
Qasr AlJabbar and Al_Musallakhah localities within the Fat'ha formation, to assess the suitability of limestone as
a major component of the mixture of raw materials for the cement manufacturing.
The results show low percent of calcium oxide and high percent of magnesium oxide, which makes the materials
unsuitable in terms of chemical composition. The percentages of silica, alumina, iron oxides, sulfate and alkali,
within the limits allowed for this industry.
The mineralogical study proved the presence of calcite and the prevalence of dolomite, which cause the
increasing of MgO. The presence of clay minerals of Kaolinite, Palygorskite, and Montmorelonite also proved.
The petrographic studies show the effect of the dissolution which lead to increase the porosity. The study
confirm the impact of the dolomitization, also, it's proved that the effect of neomorphism more than the
cementation in the rock samples.
The petrophysical studies of samples indicate high porosity and low compressive strength, density and moisture
content, which make the rocks more friable and easy for crushing and grinding during the preparation of the
mixture.
Thus, the limestone in the studied area is unsuitable as raw materials for the cement manufacturing, unless
adding of special additives or modify the rates of oxides

In this paper , we studided the problem of the autocorrelation between errors using General Least Squares
Estimation (GLS) through using the correlation matrix , which is Asymmetric matrix . We used the data obtained
from Musel dam power stations and with not denoising other problem. We found that those data have three
problems they are multicollinearity , hetroscedaticity and autocorrelation .

The Stability Analysis of Lamm equation by using Fourier mode Stability analysis in two cases has been
considered, the first one when the amplitude is constant and the second one when the amplitude is variable. In
both cases, the solution is always stablc

Multicollinearity is considered as one of the serions problem in regression analysis , so in this paper we give a
big accuracy intention to this problem and to find its solutions .We compare between pc and pls , which is
considered as one of important methods of multicollinraity MSE criterion is used for choosing the best
estimation Method

The importance of the Internet comes as the result of it's wide spread and the large number of it's users, and the
diversity of sites that covers all aspects of life. It becomes an integral part of the modern life societies. It makes a
technology and information Revolution in the various activities of social life such as economic, cultural, political
and recreational. With this expansion major it's a great important for every company to have it's own website that
enable it to display it's information of products, sections and to be as a gateway communication with the outside
world. This website did not stop on the companies, but It goes much further, It evolved significantly and appear
a specialized sites that buying and selling of products that called e-commerce sites that have spread very quickly
and has achieved a great deal with users. Therefore, the arrangement and management of these sites effects
significantly on the present and future of those companies. And in spite of that effort in the management of those
sites may not consume relatively a lot of time compared with the management of physical company's

This study sheds light upon studying condition of stability for exponential model of mixture Autoregressive by
using local linear approximation method which is used by Ozaki in studying the conditions of stability of
exponential model for Autoregressive .
This study includes finding the conditions of stability model for exponential mixture Autoregressive specifically

findings are reached for the value of non-zero fixed point and the conditions of suggested stability model

A wireless sensor network is a special kind of ad-hoc network with distributed sensing and processing capability
that can be used in a wide range of applications, such as environmental monitoring, industrial applications and
precision agriculture. Despite their potential applications, such networks have particular features imposed by
resource restrictions, such as low computational power, reduced bandwidth and specially limited power source.
In case of a network with a high density of sensor nodes, some problems may arise such as the intersection of
sensing area, redundant data, communication interference, and energy waste. A management application is
necessary to make the most of network resources. On the other hand, a high-density network can introduce a
fault-tolerant mechanism, increase precision, and provide multi-resolution data. The network density control
depends on the application. This paper proposed a method to set up which nodes should be turned off or on. The
management may take the sensor node out of service temporally. Our design uses a Voronoi Diagram, which
decomposes the space into regions around each node. That schema could be used in a management architecture
for a wireless sensor networks
