Field experiment was carried out during 2013- 2014 at the research field of the
Department of Biology, College of Science, Baghdad University, to study the
effect of bio-chemical fertilizers and chemical fertilizers on some agronomic traits
and yield components of two wheat cultivars (IPA99 and Rabyaa) under drought
stress conditions. The bio-chemical fertilizers were mixture of (Azotobacter
chroococcum. Azospirillum brasilense. and Pseudomonas fluorescens.) with
chemical fertilizers (only 50% of the recommended dosage of N and P), while the
chemical fertilizers was 100% of recommended dosage of N and P. Field plots
(1×1 m) were randomly made in the field equipped with rainfall shelter to avoid
rains. Grains of wheat cultivars were sown manually in their respective plots in rows
with a distance of 20 cm between rows and at seed rate of 3 g per row (150 kg/ha).
The experiment was conducted in randomized complete block design (RCBD) under
split plot arrangement with five replications. Adding fertilizer were kept in the sub
plot, while water stress treatment was assigned as main plot. The data were analyzed
by analysis of variance (ANOVA). Water stress was applied by irrigated the plots to
the soil field capacity then withheld next irrigation until the soil moisture of the
respective plots depleted to 80 (control), 30 % of soil field capacity. The results also
showed significant decrease antioxidant enzymes activity with the decreased water
stress. Also, the antioxidant enzymes activity (CAT and POD) were more activity
after 107 days than 65 days because of no irrigation for harvesting preparation.
Besides, at high drought level, the response of the antioxidant enzymes activity
(CAT and POD) and proline accumulation were similar to that observed in control
treatment, while with bio-chemical fertilizers the significant decreased respectively.
These bio-chemical fertilizers would play key role in productivity and sustainability
of protect the environment as eco-friendly fertilizers and cost effective inputs for the
farmers. With using bio-chemical fertilizers that contain different microbial strains
has led to decrease in the use of chemical fertilizers, which can be help achieving
sustainability of farms and with no harmful agrochemicals for human safety.

A partial temporary immunity SIR epidemic model involv nonlinear treatment rate is proposed and studied. The basic reproduction number is determined. The local and global stability of all equilibria of the model are analyzed. The conditions for occurrence of local bifurcation in the proposed epidemic model are established. Finally, numerical simulation is used to confirm our obtained analytical results and specify the control set of parameters that affect the dynamics of the model.

The authors introduced and addressed several new subclasses of the family of meromorphically multivalent -star-like functions in the punctured unit disk in this study, which makes use of several higher order -derivatives. Many fascinating properties and characteristics are extracted systematically for each of these newly identified function classes. Distortion theorems and radius problems are among these characteristics and functions. A number of coefficient inequalities for functions belonging to the subclasses are studied, and discussed, as well as a suitable condition for them is set. The numerous results are presented in this study and the previous works on this

This study is conducted to determine the effect of pathogenicity of the fungus Lecanicillium lecanii in some aspects of life of the insect saw toothed beetle Oryzaephilus surinamensis L. (Coleoptera: Silvanidae) under laboratory conditions with three concentrations of spores and mildew commentator (1 × 103, 1 × 105, 1 × 107) spore / ml , on eggs and larvae second phase of the insect .The study also includs the effect of the fungus concentrations of germination on rice (jasmine) by using direct spray treatment. The results show great fungus efficiency in the control of some aspects of life of the insect, where varied efficiency depends on the concentration of spores, The highest percentage loss of eggs is 63.33% at a concentration

In gene regulation, transcription factors (TFs) play a key function. It transmits genetic information from DNA to messenger RNA during the process of DNA transcription. During this step, the transcription factor binds to a segment of the DNA sequence known as Transcription Factor Binding Sites (TFBS). The goal of this study is to build a model that predicts whether or not a DNA binding site attaches to a certain transcription factor (TF). TFs are regulatory molecules that bind to particular sequence motifs in the gene to induce or restrict targeted gene transcription. Two classification methods will be used, which are support vector machine (SVM) and kernel logistic regression (KLR). Moreover, the KLR algorithm depends on another regress
