Sunflower yield is determined by seed (kernel) number / m –2 and by achene (fruit)
weight. Two pot experiments were carried out during two successive seasons to investigate
localized effect of GA, Kinetin or mixture of both on sink site and filling in tow cultivars of
sunflower plant. The experiment was laid out in a completely randomized block design in a
factorial arrangement with tow cultivars (Flame and Euroflore) and four plant growth
regulators treatments ( (Control , GA3 ,Kinetin and ( GA3 +Kinetin) ) with four
replications .
GA 200 ppm, Kinetin 200 ppm and (GA 200+Kinetin 200) ppm each were
applied to the buds at opening stage (45 after sowing). Comparable plants in control were
treated with distilled water. At maturity, heads were divided into four equal parts across the
center. Each of these four parts was further divided into 1 /3 equal portions i. e. peripheral,
middle and central. Data were recorded on seed weight, number of total seeds and filled seeds
for each portion, then percent increase in number of seed, percent increase in
filled seed و percentage of filled seed and mean weight of seed were calculated.
number of
For both cultivars plant growth regulator (PGRs) applications gave higher number of
total seeds, number of filled seeds and percentage of filled seed in all the three portions and
improved mean of seed weight in both seasons and as a mean of seasons as compared to their
respective controls. The most effective treatment was (GA 200 + Kinetin 200) ppm. Flame
cultivar was superior over Euroflore in number of total seeds, number of filled
seeds and
percentage of filled seeds in all the three portions and in mean of seed weight in both seasons
and as a mean of seasons.

assumption and derivation methods (Least Squares and Maximum Likelihood function), and
this building is one of the most recent studies.
And adopted in building mathematical models to test the F or T and tests the limits of
confidence and just in this research tested the F.

The effect of ageing on the lipid peroxidation and antioxidant system was evaluated in
this study . for this purpose , we determined MDA as a marker of lipid peroxidation , reduce
glutathione , uric acid as well as catalase and glutathione-s-transferase in serum of 84 male
healthy individuals (non-smokers).
These subject were divided in to three groups: group 1 ( n=28;25-34 years old) ; group2 (
n= 28;35-44 years old ); group3 (n= 28;45-63years old ).
The result showed increased level of MDA and were observed as the stage of age
increased (p >0.05). whereas there is a depletion in GSH level related to age increase ( p<
0.05), which indicate that the low level of GSH in the circulation may be due to their
increased utilization to scavenge lipid peroxide. There was higher levels of catalase and GST
in group3 compared with others. Group2 showed lower level in haemoglobin and higher level
in albumin in compared with other groups (p<.0.05). no meaningful differences were found in
terms of
serum total protein and uric acid levels.

The aim of this research is to measure temperature distribution during cutting of mild steel
process. Carbon dioxide laser is employed as a point heat source. Oxygen gas jet with low
pressure is also used Coaxially with the laser beam to produce more energy in order to reduce
the laser power consumed for this process.
Relationship between temperature and distance beyond the cut edge ( marking path ) was
found Non contact technique is adopted to achieve the target.

In this theoretical research investigation compares has been carry out
for objective and projector optical properties for asymmetrical double
polepiece magnetic lenses under magnetic unsaturated condition which whose
axial magnetic field distribution representing well known models in electron
optics have same pole shaped such as Glaser’s Bell-shaped model, power to
(3/2) model and power to (4) model. The importance of this research lie in
the fact that show which model has best objective and projector
properties, since researcher doesn’t investigate this state later.

There are many applications for elliptic curves in cryptography.Cantor's algorithm
relies on the Mumford representation of the points in jacobians. This compact representation
of points in jacobians and Cantor's algorithm make non-singular hyperelliptic curves suitable
for many applications in cryptography. This paper show the extension of cantor's
representation for singular hyperelliptic curves.

Considerable numbers of physical, chemical and bacteriological parameters were measured
at seven stations in Shatt Al-Arab and North- west Arabian gulf during the period extended
from winter 1994 to autumn 1995.
The observed densities of oil- degrading bacteria were comparable to those reported for the
same region. In general higher densities were observed in summer, while the lower densities
were recorded in autumn.
Statistical treatments of the monitored parameters demonstrated the following:
1. Stations 4,6 and 7 revealed a different trend in their distribution functions of the
measured environmental parameters varied significantly of the situations of other
stations.
2. Summer season showed dissimilar mode of variations dynamic, different largely, of
the rest seasons, while winter and autumn were coordinated- approximately, in the
same patterns of responsibility and distribution functions.
3. Same groups of environment parameters were marked in highly percentages of
representation in the principal components reflecting specific signification effects of
these parameters on the studied circumstances and occurred fluctuations.

4-amino sulphamethaoxazole was reacted with chloro acetyl chloride to convert
the
amino group to 4-chloro acetyl amino sulphamethaoxazole (compound 1).The amide was then
allowed to react with
potassium thiocyanate to prepare 4-(2-imino-4-oxo-thiazolidinyl)
compound(2) which contained thiazolidinone ring. Some aromatic amines were reacted with
4-chloro acetyl amino sulphamethaoxazole compound (1) to prepare 4-substituted anilino
acetyl amino sulphamethaoxazole compounds (1A-H).

In this work a new method for determining the specific activity for Thorium-232 was applied
by using γ-energy of 511 keV. This method was a semiemperical equation related to the
system we used it (γ -spectroscopy).It helps us to get the specific activity of Thorium at low
level count or even under the detection limit of the system.The efficiency of the detector for
511 keV that make the peak visible in the spectrum and help us to make our calculation.

Chemical determinations of Mn on (48) samples of carbonate rocks from Cenozoic
Euphrates sequence of Wadi Fuhaimi and Anah town (Western Iraq) have been carried out.
From the relationships between Mn content on one hand, the mineralogy and depositional
environments on the other, the following conclusions can be drawn: (1) Mn appears to be
mainly associated with carbonate fraction. (2) The low Mn content of the shallow water
formation reflects the original carbonate phase, mainly aragonite; sharply higher Mn content
has been found in deeper sea formation, in origin essentially calcitic. (3) Preferential
substitution of manganese for calcium in the rhombohedral structure of calcite. (4) Diagenetic
processes, particularly dolomitization, do not appear to have seriously modified the original
Mn content. (5) The relatively high Mn content in some stratigraphic levels could be related
to periods of intensive weathering and /or to a larger availability of Mn+2, due to more
reducing sea water conditions.

From the ancient times, Man had known lead. He used it in so many fields. Lead impairs
Man’s health.This impairmant appears on environmental and professional levels. Lead enters
human’s body through food, drink,air and it is absorbed by the skin because of the use of
cosmatics in which lead is an ingredient.
The aim of this study to diagnose the lead toxication by studying haematological changes
of blood cells of those who are exposed to lead and then comparing the results with blood of
persons who are not exposed to lead.This study is done through the period from July to end of
september , 2011 in Al-Jamhiri and Al-Andulus quarters at the centre of Anbar province.
Hundred samples have been collected; forty samples are collected from generators employees
and those who work in cars mending. Sixty samples are from persons who are not exposed to
lead. All samples are collected from the quarters mentioned. Also, samples are collected from
women who are not exposed to lead to measure lead toxication in men and women and then
compair the results to the normal level.It is concluded that there are changes in blood of
persons who are exposed to lead. These changes differ from those who are not exposed to
lead. It is apparent that there is reduction in total count ofwhite and red blood cells.
