CONCENTRATION OF ORANGE JUICE BY USING ROTARY VACUUM EVAPORATOR TO PROTECT FLAVOR COMPOUNDS
type: item
description: This paper is an attempt to protect the main flavor compounds in concentrated orange juice by using vacuum evaporator technique, instead of the traditional method which causes a remarkable degradation in these compounds. The physiochemical and microbial properties of juice were monitored throughout the concentration processes. Rotary evaporator technique was used at different conditions to concentrate orange juice and comparing with traditionally heat treatment. Total soluble solid (TSS), ascorbic acid, acidity, pH, viscosity and tannins have been affected by various levels according to concentration technique and period of storage. The microbial content had never developed even throughout the storage for six months, because we have added 100 ppm sodium benzoate to the fresh juice immediately after squeezing. The main flavor compounds in fresh orange juice have been monitored throughout the various concentration processes to judged their abilities for maintaining the flavor compounds of concentrated juice.

A COMPARATIVE ECONOMIC STUDY OF IMPORTED INFLATION IN THE AGRICULTURAL SECTOR IN GROUP OF ARAB COUNTRIES FOR THE PERIOD (1990-2022)
type: item
description: The research aimed to compare imported inflation in the agricultural sector in Iraq and Jordan, where data collected for time series for the period (1990-2022) and using ARDL model. The results showed a positive and significant relationship between imported inflation and both the price index of agricultural imports, agricultural product, population, agricultural trade openness and exchange rate in the short and long terms in Iraq, the variables were significant in the short term in Jordan, but in the long term some variables were not identical to economic logic, It turns out that there is a long-term equilibrium relationship between the dependent variable and some illustrative variables because not all variables have a long-term equilibrium relationship. The research recommended doing more researches and studies on inflation in the agricultural sector in Iraq and Jordan and more Arab countries and searching for other economic variables affecting inflation in the agricultural sector and reducing inflation rates that affect the agricultural sector which reflects positively on the Iraqi and Jordanian economies; Also supporting agricultural products prices and providing a subsidy for agricultural inputs for the purpose of increasing local production, developing the local economy and reducing imported inflation resulting from the increase in food and agricultural imports.

TESTING BRIGHTNESS ADJUSTED DUST INDEX (BADI) TO DETECT DUST STORMS IN CLOUDY WEATHER OVER IRAQ, CASE STUDY
type: item
description: Dust storms are frequent in many arid and semi-arid regions of the world; they are a significant environmental hazard that impacts human health, agriculture, transportation, and ecosystems, and their frequency and intensity are being magnified by climate change and unsustainable land management practices. This study presents testing and validation of a Brightness Temperature Adjusted Dust Index (BADI), designed for enhanced detection and monitoring of dust storms, particularly under cloudy conditions. The proposed BADI integrates brightness temperatures from three Moderate Resolution Imaging Spectroradiometer (MODIS) thermal infrared bands: band 20 (3.66–3.84 µm), band 31 (10.78–11.28 µm), and band 32 (11.77–12.27 µm). The efficacy of the BADI was rigorously assessed through its application to several dust storm events over Iraq, including those occurring on April 9, 20, 2022, and March 03, 2022, all characterized by significant cloud cover. Validation involved a comparative analysis with real-time RGB dust storm imagery, derived from MODIS thermal bands (B29, B31, and B32), and corroborated with in-situ meteorological data from 13 stations across Iraq. Results consistently demonstrate that the BADI exhibits superior accuracy in delineating the spatial extent and density of dust storms, even when obscured by cloud cover. Furthermore, the BADI showed strong congruence with the real-time RGB dust storm images and perfect agreement with the ground-truth meteorological observations. These findings affirm the BADI as a highly effective tool for precise and timely monitoring of large-scale dust storm phenomena, representing a significant advancement in atmospheric remote sensing capabilities.

EFFECT OF BARLEY PROLAMIN HYDROLYSATE TO INHIBIT ACE I CAPACITY
type: item
description: The aim of this work was to evaluate the potential of local barley (class Ibaa 99), an underutilized plant, as a potential functional ingredient in blood pressure (BP) treatment and health promotion. For this purpose, the ability barley prolamin isolates hydrolysate (BPIH) to inhibit Angiotensin-converting enzyme I (ACE I) was studied. Prolamin was extracted from barley, then digestion by pepsin and the effect of successive purifications using gel filtration sephadex [GF-(G25)] technology on the efficiency of ACE I inhibition capacity was studied. The results showed the efficiency of the pepsin in hydrolyzing barley prolamins, and the percentage of degree hydrolyses (DH %) increased with time. The ACE I inhibition value increased in parallel with the increase in DH %, reaching the highest value (81.44%) after 8 hours. In addition, inhibition capacity value increased after purification of BPIH using GF-(G25) to reach 88.74% in the first purification then 92.36% after the second 1. Increase inhibition was proportional to rise concentration of low M.Wt peptides of the BPIH, as the M.Wt of the peptides was less than 3.484 kDa in the first step of GF-(G25) and less than 1.470 kDa in the second step of GF-(G25), with an increase in concentration the hydrophobic amino acids (A.As) in these peptides (33 , 52.4%), respectively.

ECONOMIC ANALYSIS OF THE MOST IMPORTANT FACTORS AFFECTING THE EFFICIENCY OF BUFFALO MILK PRODUCTION IN BAGHDAD GOVERNORATE
type: item
description: This study aimed to estimate the efficiency of buffalo milk production and address the most important economic and social factors that affect the production of buffalo milk in Baghdad Governorate. A random sample of 96 out of a total of 1600 breeders was taken at a rate of (6%). The stochastic production frontier function was estimated using the maximum likelihood (ML) method between the total milk production and the quantities of production inputs, which included (total production, the quantity of dry fodder, green fodder, concentrated fodder, the number of hours of human work, medicines, vaccines, and energy) in the efficiency model, and social factors such as the family members, experience, education, number of reproduction, and age were included in the inefficiency model. The estimated parameters gave the expected signal and were statistically significant below the 5% level, except for dry food and energy. The total elasticity of productive factors was about 1.0868, which is greater than the correct one, which reflects increasing returns to scale. The average technical efficiency in the study area was (76.6%), and the efficiency ranged between (43% - 100%). This average indicates the possibility of increasing technical efficiency at a rate of (23.4%) if the causes that lead to low efficiency are addressed. In light of these results, we can conclude that there is a possibility of increasing the production of buffalo milk. This study suggests buffalo breeders should replace older buffaloes with new females, and adhere to necessary medications and vaccines to maintain the herd's health

EVALUATION OF ANTI-OXIDANT AND ANTI-BACTERIAL FUNCTIONALITIES OF COMMON CARP (CYPRINUS CARPIO) ENZYMIC ELASTIN HYDROLYSATE
type: item
description: This study was amid to assess the radical scavenging activity, reducing power and total antioxidant capacity of elastin enzymatic hydrolysate (EEH) which prepared by treating common carp bulbus elastin extract with elastase for 10 hours at 40 C°. Aliquots of reaction solution were taken every 2 hours to point out the optimum degree of hydrolysis based on the highest antioxidant value. The hydrolysate which obtained after 8 hours hydrolysis was chosen to be evaluated for improving minced beef meat shelf-life based on the bacterial contents and lipid oxidation under refrigerated storage (4 C°/ 10 days). This study included 6 groups: group C without EEH addition, groups EEH1, EEH2 and EEH3 with 50, 100 and 150 mg EEH/ 100 gm meat, in addition to group A (100 mg ascorbic acid/ 100 gm meat) and group B (100 ppm of BHT) for comparison. The antioxidant activity of elastin hydrolysate was proportional to the time of hydrolysis, where the highest radical scavenging activity (RSA) and total antioxidant capacity (TAC) were achieved after eight hours of hydrolysis (21.44 % and 205.41 mg equivalent ASC/ 100 ml respectively). While the highest value for reducing power test was after ten hours of hydrolysis (0.422 nm). The results indicate that the concentration of elastin hydrolysate was an effective factor in reducing the peroxide value (PV), Thiobarbituric acid (TBA) and total volatile nitrogen (TVN) during storage period. Meanwhile, the pH value was increased with increasing the concentration of elastin hydrolysate, while the free fatty acid (FFA) values varied during storage when the EEH3 group was recorded the least FFA value. The bacterial contents of minced meat were declined with increasing the concentration of EEH, where EEH3 group recorded the lowest count of TPC, S. aureus and Salmonella as compared to A, B and C groups. In conclusion, the fish enzymatic elastin hydrolysate is a promising natural antioxidant/ antibacterial as a good alternative for synthetic compound.

PREPARATION OF PEPTIDE HYDROLYSATES FROM BETA CASEIN ISOLATED AND PURIFIED FROM IRAQI CAMEL MILK
type: item
description: The current study aimed to isolate and purify the Beta Casein (β-CN) protein from Iraqi Camel milk by urea, and ion exchange chromatography using a DEAE-Cellulose column, and gel filtration by using a Sephadex-G100 column, determining the molecular weight (M.wt) of protein isolate by polyacrylamide gel electrophoresis in the presence of the denaturant Sodium Dodecyl Sulphate (SDS). Enzymatic hydrolyzates were prepared using both pepsin and trypsin enzymes and their mixture (1:1), then the degree of hydrolysis (DH) was estimated after incubation for 8 h. and compared with bovine protein and standard proteins, the elution of β-CN using a DEAE-Cellulose column showed the appearance of two separate peaks, and their molecular weight was 24 KDa and 20 KDa Respectively. The Sephadex-G100 gel filtration technique also showed the appearance of a single peak whose molecular weight was 24 KDa compared to β-CN, which weighed 23 KDa. The results showed that the highest degree of decomposition was 52.32% by using a mixture of pepsin and trypsin. The results indicate that the protein β-CN separated from camel milk can be highly purified using ion exchange chromatography and gel filtration techniques, and peptide hydrolysates can be prepared from it.

EVALUATION OF SIX ESSENTIAL OILS FOR CONTROLLING COTTON APHID AND POTENTIAL USE IN THE ORGANIC AGRICULTURE
type: item
description: The cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae), is one of the most widespread pests worldwide on host plants, including fruits, vegetables, and ornamental plants, in open fields or under greenhouse conditions. Their damage is not only caused by sucking the juice from plant tissue but also by their ability to transmit many viruses. In this study, A. gossypii individuals were collected in the seasons of 2022 and 2023 in order to conduct a series of bioassay experiments to evaluate six essential oils, which were Cloves (Syzygium aromaticum), Thyme (Thymus vulgaris), Rosemary (Salvia rosmarinus), Lavender (Lavandula coronopifolia), Coriander (Coriandrum sativum), and Anise (Pimpinella anisum), toward A. gossypii adults in different concentrations under laboratory conditions. Results showed that all tested essential oils had varying effects on A. gossypii adults. The most effective essential oil was Cloves, with an LD50 of 2.98, followed by Thyme and Lavender, with LD50 at 3.28 and 4.40, respectively. While other essential oils, Rosemary, Coriander, and Anise, had fewer effects against A. gossypii. The results suggested that Clove, Thyme, and Lavender essential oils, at the corresponding doses, can be used as insecticides as a safe alternative to synthetic pesticides in both IPM and organic approach farms to manage A. gossypii.

ISOLATION AND CHARACTERIZATION OF MESORHIZOBIUM STRAINS FROM WILD AND CULTIVATED CHICKPEA NODULES IN THE KURDISTAN-IRAQ
type: item
description: The study was conducted to investigate symbiosis and node-forming ability of Mesorhizobium bacteria in chickpea (Cicer arietinum L.) growth under challenging environmental conditions. Nodules were collected from wild and cultivated chickpeas in the Kurdistan Region. Endophytic bacteria associated with their roots were isolated and characterized. All the 30 isolates, were found to be gram-negative with smooth, circular colonies. Most isolates (80%) were mucoid, while 20% were not and produced green colonies on bromothymol blue. Half of the isolates 50%) grew best in alkaline pH (6.6-10.5), 26.6% thrived in acidic pH (3.5-5.5), and 20% preferred neutral pH. Regarding salt tolerance, 63% of the isolates grew well in 0-4% NaCl, while 6.67% tolerated up to 6% NaCl. In terms of temperature, 56.67% grew better in the range of 15-35°C, while 36.67% thrived in 25-40°C. Some isolates had slow growth in alkaline conditions, producing blue colonies, while fast-growing isolates in acidic conditions yielded yellow colonies. This research provides insights into the adaptability of these bacteria under harsh conditions of high pH, salinity, and extreme temperatures. The outcomes offering a pathway to improving chickpea resilience and productivity in marginal lands of the Kurdistan Region and similar sites worldwide, through utilizing indigenous candidate rhizobia for adverse environments.

SYNTHESIS, CHARACTERIZATION AND APPLICATION OF NEW CROSS-LINKED AND MODIFIED POTASSIUM POLYACRYLATE AS SOIL AMENDMENTS
type: item
description: This study was carried to investigated Two types of new grafted polymers were prepared through chemical blending (mixture of the crosslinked mixture polymerization) of potassium polyacrylate (KPA) and 2-amino acetic acid (glycine) with calcium nitrate to give graft polymer type-1 (KPA-g-CaGY). As well as reaction of potassium polyacrylate (KPA) with calcium nitrate and chitosan polymer to give graft polymer type-2 (KPA-g-CaCS), grafting polymers has been characterized by FT-IR, 1HNMR spectroscopy and compared with the pure potassium polyacrylate. The prepared polymers were used after confirming their diagnosis and physic-chemical properties in trying to reclaiming the desertification and saline soil in (Abu Ghraib-Baghdad in July 2023) by planting Iraqi sorghum type-70. Physical properties were test (before/after planting) by XRD of (KPA-g-CaGY) showed cross linked as crystal type-1, while KPA-g-CaCS showed cross linked as amorphous type-2 compared with KPA. In addition (SEM) Scanning Electron Microscopy of the modified polymer gave clear micrographs of the type-1 (KPA-g-CaGY) and type-2 (KPA-g-CaCS), this reinforces our claim that the polymer remains in the land after planting, after more than four months, and does not change or degradation, and enhances the use of the land for more than one season without adding the polymer to it. In addition to the equilibrium swelling percentage has been investigated in media (well water pH=8.5 and tap water pH=6.9), KPA-g-CaCS shows higher uptake of water compared with KPA and PAK-g-CaGY, suggests more hydrophilicity absorption at different times.

EFFECT OF FASN AND ANXA9 GENE POLYMORPHISM ON GENETIC VARIATION, QUANTITATIVE AND ECONOMIC IMPACT OF LAMB'S WEANING WEIGHT
type: item
description: The objective of the current study was to investigate the effect of FASN AND ANXA9 gene polymorphism on genetic variation, quantitative and economic influences, and the extent of their contribution to the variation in the weaning weight of Awassi lambs based on the genetic polymorphism of their dams. New equations were designed and modified to calculate the contribution of both genes to the weight and price of the lambs. The contribution of both genes to the heritability of lamb's waning weight and the expected quantitative and price values to be inherited by the next generation were also estimated. Results revealed that the AA genotype of the FASN gene was superior to its hetero genotype AT counterpart in price and quantitative values. Moreover, the FASN gene was superior to the ANXA9 gene in both counterpart values. In conclusion, The FASN gene can be adopted as linked to the lamb's weight. It is considered an influential and effective gene in the studied trait and can be relied upon in selecting the dam ewes in the sheep flocks.

description: This study aimed to evaluate the effectiveness of some plant extracts of yerba mate Ilex paraguariensis and Cinnamonum cassia against the pathogen Vairimorpha (Nosema) ceranae in the digestive system of workers of the global honey bee Apis mellifera L. at different concentrations, and showed The results of the laboratory study showed that the alcoholic extract and powders of mate and cinnamon plants at concentrations of 1, 2, and 3% were efficient concentrations and had no side effects on bees. The alcoholic extract of mate at a concentration of 3% was more efficient than the rest of the other concentrations and reached 2070, 1980, 1730, 1390,1080 and 70 x 103 spores / ml respectively with a reduction rate of 97%, The alcoholic cinnamon extract, at a concentration of 3%, was more efficient than the other concentrations, reaching 2600, 2350, 2260, 2190, 1750, 1390, and 1140 x 103 spores/ml respectively with a reduction rate of 56% after 1,3,7,14,21, and 28 days respectively. Yerba mate powder at a concentration of 3% was more efficient than the rest of the other concentrations, which reached 2470, 2240, 2080, 1750, 1460, and 1020 x 103 spores / ml respectively with a reduction rate of 61%, and cinnamon powder at a concentration of 3% reached 2530, 2440, 2280, 2050, 1920, and 1810 x 103 spores/ml respectively with a reduction of 33% after 1,3,7,14,21, and 28 days respectively.

STATISTICAL OPTIMIZATION OF MEDIUM COMPOSITION FOR MELANIN PRODUCTION BY LOCAL ISOLATE OF STREPTOMYCES ATROVIRENS TA4
type: item
description: Melanin pigment has broad applications in medicine, cosmetics, and agriculture. In this study, Streptomyces atrovirens TA4, a soil isolate was used for the first time to produce bioactive melanin pigment. This work mainly focuses on media optimization and using statistics to obtain optimum concentrations of the medium composition for maximum pigment production. Starch casein broth was the best melanin pigment-producing medium (127.6 mg/L ) among 8 tested media. Central composite design analysis using (Design-Expert-13), a statistics-based method, revealed casein as the most significant factor affecting melanin production with an F-value of 1878.8 and the model exhibited good fitting, with a correlation coefficient of 0.88. An experimental model was generated according to the values of response resolved in the designed experiment and the R2 value was 0.8174. The suggested optimal concentrations of (starch, casein, KNO3 and Nacl) were (20 g\L, 3 g\L, 0.5 g\L and 1 g\L), respectively. The model's accuracy was determined and results showed that the melanin pigment yield was 123 mg\L which was Approximately matches the predicted value (109 mg\L).

ECONOMIC ANALYSIS OF FACTORS AFFECTING OFF-FARM LABOR SUPPLY IN BAGHDAD GOVERNORATE
type: item
description: This research aimed to examine how farmers are impacted by risk by estimating the off-farm labour supply model. The study used a qualitative response model to determine the extent to which independent factors influence the dependent factor, using the Probit model. Information was collected randomly from 134 farms it included all crops grown in it of the agricultural divisions of Baghdad Governorate's Karkh and Rusafa sides for the season 2021/ 2022. The research found that the size of the agricultural family is directly proportional to the probability of participating in work outside the farm, as its parameter was 0.015. Also, the higher the educational level of the farmers, the greater the likelihood of participating in work outside the farm. Farm by 0.364. It is also noted that the inverse proportion between the size of the total holding and the percentage of participation in work outside the farm reached 0.011. Likewise, when animal income based on the availability of farm animals increases, it is inversely proportional to the probability of participation in work outside the farm. Therefore, the research recommends reviewing agricultural holding laws, preparing land use maps, reforming small agricultural holding laws and systems, and developing risk management strategies by providing adequate financing and banking facilities.
