EVALUATION THE EFFECT OF SYNTHESIZED ZINC OXIDE NANOPARTICLES FROM MYRTUS COMMUNIS L. LEAVES EXTRACT ON ESCHERICHIA COLI
type: item
description: This study was aimed to estimate the effect of zinc oxide nanoparticles synthesized by Myrtus communis L. on the expression of the adhesion genes fimH and fimA in isolates of uropathogenic Escherichia coli (UPEC). The biosynthesized-ZnO NPs was characterized through several techniques including UV–vis spectral analysis, atomic force microscopy (AFM), Field Emission Scanning Electron Microscope (FE-SEM) and Fourier transform infrared (FTIR). For determination of MIC and sub-MIC of ZnO NPs, only 7 multi-drug resistant (MDR) and strong-biofilm producer E. coli isolates (harbored both fimH and fimA) were selected based on our previous work. Microtiter plate method was utilized and the results indicated that only three isolates (C1, C2 and C23) with MIC and sub-MIC (125 and 62.5 µg/ml), respectively, were selected for further experiments. Quantitative Real Time PCR was utilized for determining the gene expression of fimH and fimA in three isolates (C1, C2 and C23), with and without treatment with ZnO NPs. According to the results, the relative expressions (2-ΔΔCt) of fimA gene in C1, C2 and C23 isolates of E. coli were downregulated in 0.51-fold after treated with 125 µg/ml of ZnO NPs, while the relative expressions (2-ΔΔCt) of fimH gene in C1, C2 and C3 isolates of E. coli were upregulated in 4.42-fold after treated with 125 µg/ml of ZnO NPs.

EVALUATING GERMAN CHAMOMILE'S ACTIVITY AGAINST ENTEROCOCCUS FAECALIS ISOLATED FROM ROOT CANALS
type: item
description: This study was aimed to investigate German chamomile extract's active ingredients and their antibacterial activity against Enterococcus faecalis (E. faecalis) which was previously isolated from root canals. Chamomile hydroalcoholic extract was obtained by maceration process. Phytochemical tests and thin layer chromatography (TLC) used to detect active ingredients in the extract. Agar well diffusion method was used to compare antimicrobial effect of 3% sodium hypochlorite (NaOCl) and 4 extract's concentrations (100mg/mL-400mg/mL) against E. faecalis. Chamomile's anti-biofilm effect against E. faecalis biofilm was tested by microtiter plate assay with ELISA reader. Phytochemistry showed that, tannins, glycosides, alkaloids, flavonoids, and polyphenolic chemicals were abundant. TLC revealed presence of phenolic compounds including; caffeic acid, chlorogenic acid, and others, and flavonoids such as; apigenin, catechin, and others. Agar well diffusion showed higher inhibition zone diameter for 200mg/mL, 300mg/mL, and 400mg/mL chamomile in comparison to 3% NaOCl. The extract showed strong E. faecalis biofilm inhibition by all its concentrations, while moderate inhibition exerted by NaOCl. It can be concluded that German chamomile extract appears rich antimicrobial and effective inhibitor against E. faecalis biofilm.

Study of some plant species as phytoremediation of heavy metals emission from oil refinery
type: item
description: This study was carried out to investigate the phytoremediation potential of six different plant species (Melia azedaracch ,Punica granatum,Cupressus arizonica, Platanus orientalis and Platanus orientalis) in the city of Erbil mitigating heavy metal emissions of an oil refinery. The research assesses photosynthetic pigments, heavy metal concentrations (Fe, Cu, Mn, Ni, Zn, As, Pb, Co, Hg and Se) from an oil, and biochemical attributes in leaves, highlighting their responsiveness to contamination. Variations in metal levels between control and polluted sites underscore the refinery's impact, while reduced photosynthetic pigments indicate potential ramifications for plant vigor. The intricate interplay between pollution levels and plant physiology is explored, offering crucial insights for effective environmental management strategies. Metals like Arsenic, Cadmium, Lead, and Mercury, commonly found in food, pose health risks due to human activities. The research underscores the significance of plants as indicators and reducers of pollutants, emphasizing the potential of phytoremediation in addressing environmental challenges. The findings contribute valuable information for developing sustainable approaches to combat pollution, particularly in industrial settings

ROLE OF COLCHICIN AND MANNITOL IN INDUCING GENETIC VARIATIONS AND DROUGHT TOLERANCE OF BARLEY VARIETIES IN VITRO
type: item
description: This study was aimed to inducing genetic variations for drought tolerance in vitro for callus three varieties Ebaa265, Ebaa99 and Bouhoth244 of barley (Hordeum vulgare L.) using plant tissue culture technique. An experiment was conducted in plant tissue culture laboratory at the College of Agricultural Engineering Sciences, University of Baghdad during the years 2022-2023 .The experiment included the use of colchicin at concentrations of (0,2.5,5 and 7.5) mg.L-1 and for a soaking periods of (0,4,8 and 12) hours, and mannitol at concentrations of (0,2,4 and 6) g.L-1 using MS media. The results showed that there were significant differences in the average dry weight of callus before and after colchicin treatment at a concentration of 7.5 mg.L-1 for a soaking period of 12 hours and with mannitol 6 g.L-1 and the comparison treatment. The dry weight of callus before colchicin treatment reached 40.30 mg in the variety Ebaa265, was significant different of the average dry weight of callus after colchicin treatment reached 92.65 mg within the variety Bouhoth244.The PCR-RAPD with five primers (OP-A06,OP-A07,OP-A08,OP-B01 and OP-B02) examination revealed differences in the number of resulting bands and their molecular weights in colchicin treatments and the comparison treatment, in light of the results. It could be concluded that colchicin has the ability to cause genetic variations and increase the tolerance of vegetative growth to drought stress resulting from treatment with the compound mannitol in Barley.

GENETIC DIVERSITY INDICATORS IN SPP1 GENE OF LOCAL AWASSI EWES IN MIDDLE OF IRAQ
type: item
description: This study was conducted to identify the genetic diversity indicators of the secreted phosphoprotein 1 (SPP1) gene in flock of local ewe's sheep in middle of Iraq. The sample was made up of 48 ewes and the duration of the study was six months. Genetic polymorphisms were identified and four SNPs (4) variants were obtained. The average allelic abundance (Na) was 2.00, the average number of alleles affected (Ne) was 1.0539, Shannon Guide (I) 0.1163. The average allelic abundance was equal in all the variations studied (2.00) and the number of alleles affected was higher in SNP2 and SNP3, both at (1.0425) compared to SNP1 (1.0211) and SNP4 (1.1096). Obs-Hom and (0.9479) are very close to Exp- Hom and (0.9492). The individual's evidence of persistence within the Fis clan of the G, A, C and T allels of local sheep were -0.0367. The Fit's aggregate stability manual obtained according to SPP1 gene analysis is also -0.0367. Therefore, we can conclude that there is no genetic drift that causes genetic differentiation of the local sheep's sample and this may be due to the large number of rams used by matting, thereby creating an appropriate variation in flock.

ASSESSMENT OF SOIL EROSION RISK USING RUSLE IN SELECTED WATERSHEDS OF SULAIMANI PROVINCE, IRAQ
type: item
description: This study was aimed to assess the risk of soil erosion in 32 watersheds of Sulaimani province, Kurdistan/Iraq, based on Revised Universal Soil Loss Equation, GIS and RS data. The annual precipitation data were used to generate the rainfall-runoff erosivity factor using the previously developed equation for the region. The soil erodibility factor was estimated using soil particle size distribution data. The topographic factor was generated using a digital elevation model from a sentinel 2. The cover-management factor was determined by using Google Earth Engine with Landsat7 and Landsat8. While the soil erodibility and vegetation factors did not show high spatial variability across the province, rainfall erosivity showed an increasing trend from south west to north east of the region, ranged from 73 to 632 MJ mm ha-1 h-1. The results showed that the average annual soil loss for the different watersheds ranged from 2.12 to 62.05 t ha-1 y-1. The results also indicated that the main factors governing soil erosion in Sulaimani province are rainfall intensity, rugged topography, steep slopes, and sparse vegetation.

AN ECONOMIC ANALYSIS OF THE RELATIONSHIP BETWEEN AGRICULTURAL TRADE OPENNESS AND AGRICULTURAL GROWTH IN IRAQ FOR THE PERIOD (1990-2021).
type: item
description: The research was conducted to evaluate the link between agricultural trade openness and Iraqi agricultural development through the use of annual time series data from (1990–2021). This research that focuses on the Iraqi case study, as a developing country that opens up to the Global industry, and aims to identify the position of openness in facilitating agricultural development. The Research question centers around the effects of agricultural trade openness to agricultural growth or vice versa. The analysis is based on the examination of the secondary data utilizing statistics such as ARDL (Auto Regressive Distributed Lag) and co-integration analysis. The relevance of the findings results in understanding the complex causal relationship between agricultural trade openness and agricultural growth. The research conclusions indicate that the high agricultural trade openness index means that the Iraqi economy is highly dependent on the outside world, which weakens the economic and political ability to confront fluctuations in economic activity. The impact of the agricultural trade openness policy in Iraq depends on the performance of the economy in general and the quality of imported goods in particular. The co-integration test of the ARDL model shows the existence of a long-term balanced relationship between the dependent variable. The research recommends the need to enhancement the competitiveness of major agricultural products and adopts encouraging policies to enhance export. It also highlights the importance of developing effective agricultural policies that provide the necessary support to farmers, to adapt to the changes resulting from trade openness.

EFFECT OF PARTIAL REPLACEMENT OF WHEAT AND RICE FLOUR BY MODIFIED STARCH ON CAKE AND BISCUIT QUALITATIVE AND SENSORY PROPERTIES
type: item
description: This study was aimed to investigate the effect of substituting different proportions (10%, 20%, 30%) of wheat flour and Amber rice with enzymatically modified starch on qualitative and sensory characteristics of biscuits and cupcakes. The results showed a decrease in the thickness of wheat biscuits with an increase in the substitution percentage . The 30% substitution showed a significant difference compared to the others . Conversely, there was an increase in the diameter of biscuit samples, ranging from (42.00-48.30 cm), as well as the spread factor. The 30% substitution treatment showed a significant difference compared to the others. As for rice biscuits, the diameter and the spread factor values increased with increasing substitution rates. Sensory evaluation for rice and wheat biscuits indicated that substitution rates of (0, 10 and 20)% achieved similarity in aroma , taste, symmetry of form, and crumb color. However, substitution rates of 30% for both products showed a darker color, more hardness, and the development of an acidic flavor . As for the cupcakes, the specific volume decreased with increasing substitution rates. The highest values for wheat cakes were recorded at substitution rates of 10% and 20%,being 3.19 and 3.00 cm3 /g respectively. The lowest values were recorded for WC3 and RC3 (2.60 ,1.61cm3 /g). The sensory evaluation for the cupcakes samples showed no significant differences as compared to the control sample in term of moisture, texture smoothness, crumb color, and crust color. Substitution at 10% and 20% showed similarity in terms of symmetry of form, crumb homogeneity, aroma ,taste and moisture. However, the 30% substitution rate resulted in a noticeable decline in product acceptance due to a decrease in volume , texture smoothness, reduced crumb homogeneity, as well as a darker color and an undesirable flavor

ANALYSIS OF THE IMPACT OF THE GREEN ECONOMY ON SUSTAINABLE AGRICULTURAL DEVELOPMENT IN IRAQ FOR THE PERIOD (2003-2022)
type: item
description: The research aims to study the impact of the green economy on achieving sustainable agricultural development in Iraq for the period (2003-2022). The research used quantitative methods in analyzing GDP, green GDP, investment allocations for the agricultural sector, environmental allocations, cultivated areas and water imports of the Tigris and Euphrates rivers to distinguish the impact of these variables on agricultural GDP. The parameters were estimated using the Autoregressive Distributed Lag-ARDL framework. The results found that each of the green GDP, investment allocations, and environmental allocations came positive and consistent with the logic of the economic theory, while cultivated areas came positive but not significant. Rivers water flow had a negative signal due to the significant decline during the study period. The research found that the green GDP has the largest effect in agricultural GDP, and its impact is clear in advancing the development process. The research recommended the need to follow scientific methods and modern methods to reduce toxic and greenhouse gas emissions, which greatly affect pollution and agricultural production

EVALUATION ANTIBACTERIAL AND ANTIBIOFILM ACTIVITY OF Cymbopogon citrates L. ON FIMA AND PAPC GENES AGAINST Escherichia coli
type: item
description: This study was aimed to evaluated the antibacterial activity on Cymbopogon citrates ( C. citrates ) leaves extract and assessment of its effect on fimA and papC genes in Escherichia coli ( E.coli )isolates. Rotery apparatus were used to prepare aqueous and methanolic extract; total phenolic content and high-performance liquid chromatography (HPLC) were conducted to determine the active compounds in the extract. The results showed that the methanolic and aqueous extracts contain seven flavonoids derivatives ( Catechine , Chlorogenic acid , Ferulic acid , Gallic acid , P-Coumaric acid , Qurcetine and Kaempferol ) in varies ration were identified on the basis of matching retention time with the standards. The total phenolic contents were 19.56 and 47.45 mg/g in 50 mg/ml, in aqueous and methanolic extracts respectively. The antibacterial activity of C. citrates leaves extracts showed that the aqueous extract was less effective than methanolic extract in concentration 16 mg/ml. Moreover, the result of the minimum inhibitory concentration (MIC) showed that the methanolic extract on E.coli isolates was 16 mg/ml, while the MIC values of aqueous extract were 32 mg/ml. C. citrates methanolic leaves extract had antibiofilm activity, which inhibits 90% and 100% of the biofilm formation of E. coli in concentrations 16 and 32 mg/ml respectively. The result of the gene expression revealed that there is a decrease in the expression of the fimA and papC genes.

GENETIC VARIABILITY AND MOLECULAR EVOLUTION OF THE IRAQI DATE PALM CULTIVARS USING INTERNAL TRANSCRIBED SPACER 1 (ITS1) REGION OF NUCLEAR RIBOSOMAL DNA
type: item
description: This study was aimed to investigate genetic diversity of nine Iraqi date palm cultivars (Phoenix dactylifera L.), two of them were propagated by tissue culture tiqneque. The variation in GC content in the ITS1 region was recorded at (52–53%) with an average of (52.7). The data suggests that transitions have a lower frequency compared to transversions in this region, where the overall bias R for transition/transversion has been estimated at (0.661). The aligned sequences associated with internal transcribed spacer 1 (ITS1) showed intraspecific variation, and the matched sequences enabled the identification of all cultivars studied as haplotypes. Phylogenetic trees constructed using distance-based ''neighbour-joining'' (NJ) and ''maximum parsimony'' (MP) techniques provided strong evidence for the independent structure of the considered accessions. Tests of molecular evolution reveal that the internal transcribed spacer 1 (ITS1) evolved in accordance with a precise neutrality paradigm. In a population predicted to be in equilibrium after the 6th generation, suggesting a recent demographic expansion in the Iraqi date palm population.

SUPPRESSION OF THE PATHOGEN OF FUSARIUM WILT FUSARIUM OXYSPORUM F.SP. LYCOPERSICI ON TOMATO BY INTERCROPPING WITH GARLIC
type: item
description: This study aimed to investigate and evaluate the efficiency of intercropping garlic plants with tomato and their root secretions in controlling the cause of Fusarium wilt disease by using alternative methods to the use of chemical pesticides, and the experiment was carried out in the College of Agricultural Engineering Sciences/University of Baghdad. Garlic root secretions were extracted and their effectiveness in inhibiting radial growth was studied at several concentrations. The concentration of 30 µl.ml-1 showed the highest rate of inhibition, reaching 96.3%, compared to the control treatment, which amounted to 0%, and this result confirmed the ability of garlic root secretions to inhibit pathogenic fungi. The effect of planting garlic with tomatoes on plant growth-promoting rhizobacteria (PGPR) populations was also studied, and an increase was found in the numbers of these beneficial bacteria. Intercropping significantly, in contrast to monocropping, which increased by a small percentage in the fruit-setting stage and then continued to decrease in the late fruit stage. In the pot experiment, the results of using two treatments of intercropping garlic with tomato plants and watering with garlic root secretions showed a significant reduction in the percentage of infection and disease index, reaching 58.3% and 25%, respectively. The results showed the effectiveness of the treatments used in increasing the concentrations of defensive compounds such as the enzymes Peroxidase, PAL, and the content of phenols, as the FGR treatment recorded an increase in the induction and accumulation of these compounds when detected in tomato leaves, which amounted to 39 Δ absorbance.min-1.g-1, 31 nM.mi-1.g-1, and 5.47 mg of catechol.g-1, respectively.

ENVIRONMENTAL BY GENOTYPE INTERACTIONS AND THEIR EFFECTS ON GROWTH RATE OF AWASSI SHEEP REARED IN SEMI-ARID REGION
type: item
description: Due to its reputation for receiving little rainfall, Jordan's Al-Mafraq region (where the sheep is reared) is susceptible to droughts and water shortages and poor range. Estimating genetic and environmental factors for growth traits in purebred Awassi sheep in Al Mafraq (semi-arid region) was the goal of the study. The study's data came from 3481 lambs born at the National Centre for Agricultural Research's (NARC) Al-Khanasri livestock and rangeland research station in Jordan over a 15-year period (2009–2023). Birth weights (BWT), weaning weights (WWT), and average daily gain from birth to weaning (ADG) were the traits under study. While genetic parameters were estimated assuming the mixed model using the Restricted Maximum Likelihood (REML) method process using the ASReml program, the environmental effects were estimated using the SAS program's General Linear Model (GLM) technique. BWT, WWT, and ADG were significantly impacted by the year of birth, dam weight at lambing, parity, lamb sex, and method of birth; however, the examined growth traits were not significantly impacted by the dam's age (P > 0.05). BWT, WWT, and ADG had heritability estimates of 0.38±0.05, 0.21±0.05, and 0.16±0.05, respectively, and corresponding repeatabilities of 0.41±0.05, 0.39±0.06, and 0.32±0.05. Environmental correlations ranged from negative (-0.20) between BWT and ADG to high (0.98) between WWT and ADG, while phenotypic correlations ranged from negative (-0.011) between BWT and ADG to high (0.98) between WWT and ADG. The estimated genetic correlations among the traits under study were high and strongly positive, ranging from 0.54 between BWT and ADG to 0.99 between WWT and ADG. To sum up, the findings ought to be used to a genetic selection program that aims to enhance Awassi sheep's growth performance.

EFFECTS OF ALUM APPLICATION AND WATER QUALITY ON SOME PROPERTIES IN DEGRADED SOIL AND YIELD OF SORGHUM (Sorghum bicolor L.)
type: item
description: Soil degradation and water scarcity are considered the main challenges that are faced the agricultural production, particularly with changing climate. The objective of this study was to study the effectiveness of alum in improving some soil chemical properties using two qualities of irrigation water . The experimental study was conducted in the Anbar Governorate / Al-Khayrat district in the fall season in degraded clay loam soil. The experimental design for the study site was the split- Block arrangement with a randomized complete block design (RCBD) with three replicates. This study included two factors: the main factor was water quality with river water (1.8 dS m-1) and well water (3.8 dS m-1), and the secondery factor was alum application with eight levels (0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, and 1.4 %) based on dry soil. The results showed that pH, EC were decreased by 12.7, 65.1%, respectively when applied 0.8% of alum at the irrigation of river water and decreased by 11.9, 61.4 %, respectively when applied 1.0% of alum at irrigation with well water as compared to control treatment. While an increase occurred in CEC of about 20.0 and 19.8% at the irrigation of river and well water, respectively as compared to control treatment.While the addition of all levels of aluminum sulfate (alum) led to a significant effect on the available nitrogen in the soil and the biological yield when treating alum a5, which reached 48.6% and 48.50, respectively.

ANALYSIS OF DUST STORMS IN ERBIL CITY-IRAQ USING SURFACE OBSERVATIONS AND GIS TECHNIQUES
type: item
description: Dust storms are a common phenomenon in desert and semi-desert areas, they arise when the wind blows and has the ability to soil grains transfer particles from the Earth's surface and carry them over distances determined by the wind speed and the size of the particles, when this occurs Winds with a speed between (7-8) of per second and at a height of one meter have the ability to can erode soil and transport it over long distances through wind erosion. However, the geography of the study area distant from desert regions, but it is affected by global environmental changes, like most other regions of the world. Erbil city experiences the phenomenon of dust storms, to measure the amount of dust deposition in Erbil, a special glass surface measuring one meter in length and width, equipped with glass, was used to collect dust particles. A scientific analysis of dust deposition was conducted in 2024 according to the results, the maximum amount of dust deposition recorded in Erbil city was 3.5 grams in September, and the minimum of dust deposition is recorded in May 2024 was 1.2 grams, the total area corresponding to the dust deposition in Erbil in 2024 is approximately 383km, Average dust deposition per square meter in Erbil in 2024: 28.21grams , the Total of dust deposition from Erbil city in 2024: 10.8 tons .for the comparison and analysis of the resulting data, a geographic information system (GIS) is used.

MITIGATING METHANE EMISSIONS FROM ERBIL WASTE DUMPING SITE: A GIS –BASED APPROACH TO DETECTION AND CONVERSION INTO A GREEN LANDSCAPE
type: item
description: This work uses Geographic Information System (GIS) technology, particularly ArcMap, to address the serious environmental issue of methane (CH4) leaks from the Kane Qrzhala waste dumping site Sub district in Erbil City, at latitudes 36°10'23"- 36°52'25" N and longitudes 43°35'32"- 44°23'43" E. The aim of this research is to identify and analyze methane concentrations in the neighborhood of the dumping site, offering significant data for environmental monitoring and mitigation techniques. "This study employs an integrated approach combining spatial data and satellite imagery. Methane emission levels were extracted from two publicly accessible platforms: earth.jpl.nasa.gov and dataspace.copernicus.eu.”, and ground measurements to map and quantify methane emissions. The findings contribute to the understanding of the spatial distribution of methane emissions, enabling targeted interventions to reduce environmental harm. Furthermore, the research investigates sustainable alternatives to reducing methane emissions by identifying that the garbage dumping site be converted into a green area and, eventually, a forest. The methane plume spanned 26.768 km² with a concentration of 3471 ppm—over twice the safety limit—posing a serious environmental and health risk and demanding urgent action to control emissions. Beyond methane reduction, the benefits of transforming the dumping site into a green space include improved air quality, increased biodiversity, and the construction of a community recreational area. Finally, this study not only extends to our awareness of the release of methane from waste disposal sites, however it also advocates for the conversion of such sites into environmentally beneficial landscapes.

RELATIONSHIP OF APOLIPOPROTEIN A-1 GENE POLYMORPHISM WITH SOME GROWTH TRAITS OF COMMON CARP (CYPRINUS CARPIO L .)
type: item
description: The study was conducted to investigate the relationship between the polymorphisms of A, B, C, D and E of the apolipoprotein A-1 (ApoA-1) gene with some traits (daily and total weight gain rate and feed conversion rate and efficiency) in 70 samples of common carp (Cyprinus carpio). There were significant differences in the growth traits of the genotypes A, B, C and D of the apolipoprotein A-1 gene compared to the genotype E. The results showed that the genotype C was significantly superior (p≤0.05) in the daily and total weight gain rates and reached the highest value of 0.56 and 39.42 g/fish, respectively, while the genotype E decreased to the lowest value of 0.14 and 9.50 g/fish, respectively. On the other hand, the feed conversion rate recorded highest significant effect (p≤0.05) at the genotype C and reached 5.13 Compared with the E genotype which recorded 9.6, the highest significant effect (p≤0.05) on the feed conversion efficiency trait was at the C genotype at a rate of 19.49% compared to the E genotype which reached 10.41%. We conclude from the above that the ApoA-1 gene may have an effect in improving the productive growth traits in common carp fish through its effect on the quantitative traits associated with the genetic phenotypes.
