The study is to manage the salinity of the soil. The maximum number of computations, the spatial distribution of the (LR) application over the map, and the leaching requirements (LR) for reclamation purposes for various EC-tolerance crops List the following crops' water requirements: wheat, tomatoes, and grapes. All research areas are to be planted with grapes, tomatoes, and wheat, with 19139396.7 m³, 969745.57 m³, and 496236.37 m3, respectively. Grapes are more salt-tolerant than both tomatoes and wheat, and tomatoes are more salt-tolerant than wheat. Thus, the GIS-ESP map identified Three groups of crop soil with ESP tolerance: extremely sensitive crop (327.45 ha), sensitive crop (873.05 ha), and moderately tolerant crop (952.90 ha). Consequently, amounts of 27592.12 and 34490.16 tons of gypsum must be applied such as min and max all over actual GR (ATGR), respectively Gypsum requirements (GR) to reclaim soil to cultivate ESP crops at depth (D) 30 cm for Mapping unit Studied soil required gypsum applications of 4049.82and 8099.65tons as min and max all over net GR (ANGR), respectively. Gypsum requirements (GR) to recover soil at a depth (D) of 120 cm for the cultivation of ESP crops

Abstract

Cathodic protection of underground petroleum pipelines by impressed current is very important in the oil field, especially when the soil resistance to current is high. the impressed Current is direct current supplied by a cathodic protection system utilizing an external power source .With this method, the structure is placed in an electric circuit with a direct-power supply and an anode groundbed. Current is forced to flow from the electrolyte to the structure The object of this study is to design of cathodic protection for underground crude-Oil Pipeline by impressed current cathodic protection to be used in the protection of the underground petroleum pipelines for X oil field of Waha Oil Company ,

Bacterial infections causing otitis media are common in children and impact their ability to communicate and learn. These infections can lead to health and psychological complications, underscoring the need for medical intervention. The significance of this study lies in its investigation of bacterial infections in children with ear infections at healthcare centers in Zintan city, from May to August 2023. A total of 100 samples were collected from one week to five years, including 54 females and 46 males. Ear swabs were taken using sterile cotton swabs, followed by bacterial culture on various media. The identification of bacterial species was conducted through Gram staining and biochemical tests. Antibiotic susceptibility was assessed using the modified Kirby-Bauer disk diffusion method. The study identified 85 bacterial isolates, predominantly from the genera Staphylococcus, Klebsiella, and Escherichia. Gram-positive bacteria comprised 68.23%, with Staphylococcus aureus being the most common at 35.26%. Formula feeding was associated with a higher prevalence of bacterial infections (42.55%) compared to breastfeeding (38.85%). Additionally, natural delivery showed a greater prevalence of bacteria (60%) than cesarean delivery (40%). Female had a higher infection rate (56.47%) compared to males (43.52%). Antibiotic susceptibility testing revealed that Meropenem was highly effective (100% susceptibility), while Penicillin and Amoxicillin showed significant resistance (80%+). The findings of this study highlight the critical prevalence of antibiotic-resistant bacteria in pediatric ear infections, emphasizing the need for regular monitoring and tailored treatment strategies to combat resistance effectively. The study underlines the importance of antibiotic stewardship in clinical settings to enhance treatment outcomes.

Glycosylated hemoglobin (HbA1c) is the form of hemoglobin that is used widely to identify the average blood glucose levels of a person over the past three months and can correlate to complications of high blood glucose. This study aimed to determine the effect of iron deficiency anemia (IDA) on glycated hemoglobin (HbA1C) in non-diabetic pregnant women. This study was conducted on 86 pregnant women in the last trimester of pregnancy, 66 pregnant women had IDA and were non-diabetic, and 20 pregnant women were non-anemic as control, their ages were between 20 - 37 years, fasting blood sugar (FBS), glycated hemoglobin (HbA1C), hemoglobin (Hb), and the serum iron was determined on all blood sample. The mean HbA1c level was significantly lower in pregnant with IDA (4.42±0.89,) than in pregnant that have not IDA (5.35±0.38), P <0.05. Mild anemia was (56.1%), moderate anemia was (37.9%), and severe anemia was (6.06%), The mean HbA1C level in cases of mild anemia was slightly higher than in non-anemic pregnant, (5.42±0.69.,5.4±0.38), with no significant differences, while in the cases of moderate anemia, the mean of HbA1C level was lower than non-anemic pregnant 4.6±0.85, with significant differences at P <0.05. the mean HbA1C level in cases of severe anemia was lower than its level in non-anemic pregnant ( 3.45. ± 0.29) with significant differences at (P < 0.05.), there was a
