Infection caused by the fungus candida is potentially fatal, A highly active of phospholipase
activities was identifide , Analysis of products hydrolysis showed that the enzyme activities were
phospholipase using TLC technique to know the producing fatty acids by using standard material
from this acids was studied, some kinetic function for this enzyme was studied.

A method of analysis is presented for the class of binary sequence generators
employing the product of outputs of two or more linear feedback shift registers
with maximum period.The linear feedback shift registers are represented in terms
of the roots of their characteristic equations in a finite field , and it is shown that
nonlinear operation inject additional roots into the representation .The number of
roots required to represent a generator is a measure of its complexity , and equal
to the length (number of stages ) of the shortest linear feedback shift register that
produces the same sequence .The analysis procedure can be applied to any
arbitrary combination of binary shift registers , and is also applicable to the
synthesis of complex generators having desired properties.Although the discussion
in this paper is limited to binary sequences, the analysis is easily extended to
similar devices that generate sequences with numbers in any finite field.

Since the USA and its allies have been used a new radiological weapons called the
Depleted Uranium Projectiles against Iraq and its people during the occupation
Iraq in 2003 , major environmental and human health problems have resulted
from the use of these weapons. Thus, such problems and their possible sources
should be investigate all over Iraq .
The exposure rates to external radiation were measured in 37 regions in the study
area . by Inspector Radiation ALERT detector.made in USA .
The average of the exposure reading shows an increase as high as 80 and 85
µR.hr-1in Sumer region and Al kamessia region respectively, which indicates the
presence of radiological pollution in the study area . These values are generally
above the critical level .The internal and external doses of the people have been
exposed to, are calculated and external exposure are found to be 80 m Sv and
85mSv respectively in Sumer region and Kamessia region.

The study was carried out to investigate the distribution of concentrations two heavy
metals Cobalt (Co) and Nickle (Ni) [as heavy metals] in plankton (phytoplankton and
zooplankton) and in its surrounded habitats(water, sediment and aquatic plants) in two
rivers (Euphrates and Al-Garaf) at Al-Nassiria city ,southern of Iraq, for one year
(January-December,2004) .
Results showed considerable seasonal variations in the concentrations of these two
metals. Ni concentration in plankton and aquatic plants were found to be greater than that
of Co in both rivers, while the concentration factor (plankton /water) and (aquatic plants
/water) for Ni was greater than for Co in both rivers.

As computers have become an integral part in the life of the societies all over the world ,
people are increasingly using computer technologies including the internet, and particularly the
e-mail , to communicate encouraged by the easy access to these technologies and their lower
cost . This, in turn, has led to a growing field of study which is Computer – Mediated
Communication (CMC) part of which e-mail is expected to be the most familiar and the
widely-used mode of communication exchange. Within the course of its relatively short time
of use, e-mail has shaped its (approximately) regular format so far, but its language (English
only for the purpose of this paper) has shown irregular manifestations in the message texts .
This study tackles this issue of the characteristics of the language of e-mail including its
format as compared to the conventional letter. It emphasizes the hybrid nature of the English
texts of emails which is being under a process of linguistic systemization as an indication that
it is on a way of standardization . Therefore , the scope of the study is limited only to email ,
and doesn't go beyond studying its language features .
The methodology followed starts with reviewing some topics about email format and
language referring to the literature in the field in which the recent writings on the Net provide a
major reliable reference to the study . Then the prevailing characteristics of the language of
email are also shown illustrated with examples from random samples of email texts . Brief
citation of the "Netiquette" is necessarily presented , and the appendices of emoticons ,
acronyms and abbreviations used in email are to support indicating the systemization being
processed towards the standardization of the language of email .
The conclusion then confirms the fact of the hybrid nature of the email language as a
composite of both spoken and written English in addition to other language characteristics
unique to email , but this hybridization is now being systemized as all the linguistic
manifestations (whether in format , words , phrases , structures or even emoticons and
abbreviations …etc ) have come to be understandable and agreed-upon , and have already
been grouped in alphabetical glossaries and dictionaries ; this , in itself , is a step on the way of
standardization and a case that supports emailers to reinforce this specificity through their
daily use and most probably "impose" more standards for the language of email with the
course of time .

Antioxidants are the substrates which can prevent free radicals generation and protect the
cells from membrane oxidation that cause cells damage and tissue injury. In this study, we
attempted to compare between tannic acid (TA) and ascorbic acid (AS) antioxidative activity in
vitro. The study included fifty healthy subjects, and serum lipid peroxidation (LPO) was
promoted by incubation with copper ions(copper sulphate).The results illustrated that the
optimum concentration of copper to promote lipid peroxidation in sera was (0.1 M) with
incubation at 37°C for (1 hr). The concentrations of (AS) (10-5
and 10-4 M) could not inhibit
(LPO), whereas the concentrations (10-3
, 10-2
, 10-1
, 0.2) had a certain effect on (LPO) and could
not decrease malondialdehyde (MDA),LPO marker, levels to the normal values with negative
correlation coefficient ( r= -0.72 ).Yet all TA concentrations(10-5
, 10-4
, 10-3
, 10-2
, 10-1
, 0.2, 0.3)M
were able to inhibit (LPO) and decrease (MDA) levels to the normal values at concentrations
(10-1 M and up ), also TA concentrations were correlated negatively with ( MDA) levels (r =-
0.90).

The polarization mode dispersion,


, and birefringence,


, vectors have the
same meaning in a certain cases, but in general they are different. In this paper, we
introduce a new theoretical comparison between these two vectors through the
propagation in optical fibers. The parameters; the angle between


and


, and the
value of


depend on the adopted form of the vector


. In addition, the value of


depend on the number of orders that is used to for account the vector


. We
introduce also a new formula of the dynamical polarization mode dispersion
equation which contains the circular birefringence and the higher orders of the



.
