The experiment was conducted in twodifferentsplaces, one of this experiment in the field was not under salt stress and the other experiment field was under salt stress.Those experiments were conducted in college of AgricultureDiyalaUniversity atautmyseason (2015 - 2016)to study the salt stress by usingseeds soaking with Hydrogen Peroxide and foliar application in different concentrations ofAbscisic acid.The experiment statistical design as RCBD was with three replicates.Soaking the seeds withHydrogen Peroxidetreatments 0 , 10 , 15 , 20 mmol.L-1. Three Abscisic acid levels0 , 15 , 30 mg.L1.α -Tocopherol, Catalase Enzyme, Membrane Stability Index,proline content, leaves area andpercentage of Electrolyte Leakage of Wheat, were measured. Results drawn from these were as follows: The α -Tocopherol concentrations, Catalase Enzyme,Proline content and percentage of Electrolyte Leakageincrease withsalt stress for soil,comparing with soil not under salt stress. The results showed that fourth level of Hydrogen Peroxide Soaking(20)superior on the levels (0)of α-Tocopherol concentrations, Catalase Enzyme,Membrane Stability Index, proline acid concentration and leaves areaincreased in values(78.88%, 135.54%, 17.47%, 34.04% ,16.36%) respectively with soil under Salt Stress.The results show increase in α-Tocopherol concentrations, Catalase Enzyme and percentageof Electrolyte Leakagewith low amount of Abscisic acid sprayingABA0(0 mg.L¹)comparing with the ABA1(15 mg.L-¹)and ABA2(30 mg.L-¹),but the treatment of spraying abscisic acid outperformedsignificantly increasedin the Membrane Stability Index anproline acid concentrationin leaveswith increase at the level ofABA2(30 mg. L-1)compareing with the other levels ofin the soil under salt stress. Theα-Tocopherol concentrations and Catalase Enzyme wereincreasedsignificantlyby interaction between(20mmol.L-1H2O2 +0 mg ABA.

The Catalase Enzyme increase in the level(20 mmol.L-1H2O2 + 0 mg ABA .L-1) in the soil that was not under salt stress.Interference between (20 mmol.L-1H2O2+30mgABA.L-1) showedinsignificant effect on the Membrane Stability Indexandproline acid concentrationsin leavesat the soil that was under salt tension and proline acid concentrationsat leaves in the soil which was not under salt stress.Also most of characters in plant were significantly influenced by Hydrogen Peroxide under salt stress.
This study was conducted to evaluate the activity of pomegranate (Punica granatum L.) peel powder and Pseudomonas fluorescens against Pythium aphanidermatum the causal agent of cucumber seedlings damping-off. Results showed that augmenting of pomegranate peel powder at 2%, P. fluorescens suspension contain 4×107cfu/ml, and the fungicide Previcure N at 0.5 ml/L to culture media (PDA) were inhibited the pathogen growth by 100, 100 and 72.1% respectively. Results of greenhouse experiment indicated that treatment of cucumber seeds with pomegranate peel powder, reduced pre-emergence damping-off percentage to 3.3% compared with 16.6% disease with P. fluorescens and 96.6% in control treatment (pathogen only). No significant differences were ob

It aids in the extraction of the required information from such networks and has a vital role in different fields that range from healthcare to regional geography, economics, human interactions, and mobility. The method for detecting the structure of communities involves the partitioning of complex networks into groups of nodes, with extensive connections within community and sparse connections with other communities. In the literature, two main measures, namely the Modularity (Q) and Normalized Mutual Information (NMI) have been used for evaluating the validation and quality of the detected community structures. Although many optimization algo

The easternmost extent of the Pharaoh Eagle Owl Bubo ascalaphus (Savigny, 1809)
distribution has remained enigmatic due to id entification problems and lack of owl research.
In Iraq, B. ascalaphus has been reported from only few localities in western Iraqi deserts;
while its occurrence in Iran has not been reported before this study. In 2017 2020, several
new records of B. ascala phus in western through southeastern Iraq were made and a new
distribution range in western Iran was confirmed. Furthermore, field identification,
interspecific relationships and conservation status of B. ascalaphus in Iraq and Iran were
comprehensively di scussed.

Background: Prophylaxis methods are used to mechanically remove plaque and stain from tooth surfaces; such methods give rise to loss of superficial structure and roughen the surface of composites as a result of their abrasive action. This study was done to assess the effect of three polishing systems on surface texture of new anterior composites after storage in artificial saliva. Materials and methods: A total of 40 Giomer and Tetric®N-Ceram composite discs of 12 mm internal diameter and 3mm height were prepared using a specially designed cylindrical mold and were stored in artificial saliva for one month and then samples were divided into four groups according to surface treatment: Group A (control group):10 specimens received no surfa

In this work, pure Polypyrrole (PPy) and Polypyrrole (PPy)/Graphene (GN) was synthesized by in-situ polymerization in different weight percentages (0.1, 0.3, 0.5, 1, 3 and 5 wt.% (g)) of GN nano particles using chemical oxidation method at room temperature. The FTIR, SEM and electrical properties were studies for the nano composites. The result show that when concentration of GN Nano particle increase, the electrical conductivity increased and the graphene sheets were merging to form a continuous area of the GN through the polypyrrole base material. The FTIR spectra shows that the characteristics absorption peaks of polypyrrole that is, 1546.80, 1463.87 and 3400.27 cm-1(stretching vibration in the pyrrol

Theoretical spectroscopic study of Beryllium Oxide has been carried out, Boltzmann distribution of P, Q and R branches in the range of (0<J<13) at temperature 4200K for (0-0) band for electronic transitions B1Σ+-A1Π and B1Σ-X1Σ. The Boltzmann distribution of these branches has a maximum values at equal J approximately while the values of relative population are different. For the B1Σ+- X1Σ+ transition the branch's lines extend towards lower wavenumber. This is because (Bv'-Bv") value is negative, i.e Bv'< Bv" For B1Σ+-A1Π

New Schiff bases derivatives [IV]a-e is prepared via condensation of Derythroascorbic acid with p-substituted aldehydes in dry benzene. To obtain these derivatives, the 5,6-O-isopropylidene-L-ascorbic acid[I] was chosen as starting material, compound prepared from the reaction of L-ascorbic acid as starting material. Compound[I] was prepared from the reaction of L-ascorbic acid with dry acetone in the presence of hydrogen chloride. The esterification of hydroxyl groups at C-2 and C-3 positions with excess ofethyl α –chloroacetate in the presence of sodium acetate produce acorresebonding ester [II] , which was condensed with hydrazine hydrate to give new hydrazide [III] . The new Schiff bases [IV]a-e were synthesized by reaction of acid h
