Field and laboratory experiments were conducted during the course of study to
test if the sunflower residues along or with 50% full rate of trifluralin herbicide has
any impact on mycorrhizal association and soil nitrification which are important
processes for improving growth and productivity of crops. Results revealed that
incorporation of sunflower residues significantly increased spores number at 2, 4
and 6 weeks of residue decomposition compared to control treatment. However,
when the residues applied in combination with reduced rate of trifluralin herbicide,
sporulation was appreciably decreased by sunflower residues at 3 t ha-1 but it
remains almost the same at 6 t ha-1 rate of residues. Field soil amended with label
rate of trifluralin showed lower sporulation during the first six weeks from
beginning of the experiment. Colonization rate was appreciably increased by
application of sunflower residues at 6 t ha-1 and decreased by label rate of herbicide
and weed free treatments. The highest colonization intensity (83.4) was recorded by
application of sunflower residues at 6 t ha-1, followed by treatment of sunflower
residues at 3 t ha-1 (72.2). Label rate of herbicide recorded the least colonization
intensity (54.4). Incorporation of sunflower residues at 3 and 6 t ha-1 significantly
reduced nitrification rate at all incubation periods in comparison to control.
However, when the residues was applied along with the reduced rate of herbicide,
nitrification rate was significantly increased over the sole application of sunflower
residues at all incubation periods except 4 and 8 days incubation periods but it
remains below control. Soil sterilization treatment showed the least nitrification rate
at all incubation periods. In all bioassay experiments, the amounts of NH4
+
converted
in the incubated soil was significantly correlated with the amount of NO3
- produced
over the periods of incubation suggesting that soil incubation is efficient method that
can be used for measuring nitrification process.It can conclude Sunflower residues
amended in field soil was found to provide a good medium for growing Glomus
mosseae fungus and best way to inhibited nitrification rate and thus may contribute
in alleviating losses of NO3 used by plants and reducing the environmental
pollution.
Abstract:
The purpose of this research is measuring relationship level and impact between Organizational Factors and their Dimensions (Leadership, Organizational Structure, Organizational Culture), and Talent Management Strategies (Talent Recruitment,Talent performance management, Talent Development, Talent Retention ). it was relied on the Questionnaire form as a basic instrument in collecting the Data by using (Likert) instrument ,which was distributed on the research Sample which number was (100) individual included (Managers of schools, assistants (scientific and Administration ) and teachers in Four schools of Talents in Iraq (Baghdad , AL-Nagaf , AL-Basra, Mesan).

Show MoreThis paper presents a point multiplication processor over the binary field GF (2233) with internal registers integrated within the point-addition architecture to enhance the Performance Index (PI) of scalar multiplication. The proposed design uses one of two types of finite field multipliers, either the Montgomery multiplier or the interleaved multiplier supported by the additional layer of internal registers. Lopez Dahab coordinates are used for the computation of point multiplication on Koblitz Curve (K-233bit). In contrast, the metric used for comparison of the implementations of the design on different types of FPGA platforms is the Performance Index.
The first approach attains a performance index

Objective: to assess maternal knowledge related to anaemia during pregnancy.
Type of the study: A cross –sectional study.
Method: The study including 200 mothers who attended selected primary health care centres, Baghdad during November and December 2015, they completed a previously prepared questionnaire coveringsocio-demographic characteristics and knowledge regarding anaemia in 4 main domains.

The inflammatory effects of periodontal disease help to promote endothelial dysfunction in arteries which may lead to changes in blood pressure. Salivary MMP-8 has been associated with both periodontal disease and prevalent hypertension. Aim of study: This study was conducted to measure salivary matrix metalloproteinase - 8, in relation to periodontal health condition among a group of patients with hypertension in comparison with control group. Materials and methods: Ninety subjects, aged 45-50 years old were included in this study, seeking treatment for chest pain in Ibn-A

Detection of virulence gene agglutinin-like sequence (ALS) 1 by using molecular technology from clinical samples (
The aim of this study to determine the genetic distance and relationship among some Iraqi date palm cultivars by using the Random Amplified Polymorphic DNA (RAPD) technique. Molecular analysis was performed by using 10 random primers. These primers produced 176 fragment lines across 14 cultivars, Of these, 166 or 94.3% were polymorphic. The size of the amplified bands ranged between 200-2250 bp. The genetic polymorphism value of each primer was determined and ranged between 7.5-16.9%. In terms of unique banding patterns, the most characteristic banding pattern was for the Barhee cultivar with primer OP-M06 and for the Khadhrawy Mandily cultivar with primer OP-C02. Genetic distance values ranged from 0.868 to 0.125 among studied date palm
