This study was conducted in a lath house, Dept of Hort. and Landscape, College of Agricultural Engineering Sciences, Univ. During the 2021 growing season, Baghdad will investigate the influence of organic and Biological fertilizers on three Citrus rootstocks' growth and leaf mineral content. The first factor is the addition of liquid organic fertilizers Vit-Org (O) at three levels without addition (O0), soil addition at 10 ml.L-1 (O10) and soil addition at 20 ml.L-1 (O20). The second factor is the addition of nitrogen-fixing bacteria without addition (N1), add 30 ml.Transplant-1 of Azotobacter chroococcum (N2) and add 30 ml.Transplant-1 of Azospirillum brasilemse (N3). The third factor is three citrus rootstocks: sour orange (R1), Rangpur (R2), and C-35 Citrange (R3). Treatments were replicated three times (three transplants in the experimental unit) at split blocks design in an R.C.B.D. The number of transplants used was 243 transplants. The experimental results showed that the addition of Vit-Org liquid organic fertilizer had a significant effect in increasing vegetative growth characteristics and leaves mineral content, as treatment with a concentration of 20 ml.L-1 (O20) was superior to increase in stem diameter of 2.99 mm and increase in leaves nitrogen content of 1.49%, phosphorous was 0.35%. Treatment with a concentration of 10 ml.L-1 (O10) was superior in increased leaves number of 66.27 leaves: transplants-1 and leaf area of 17.70 cm2 . The addition of nitrogen-fixing bacteria, especially the addition of Azospirillum brasilemse (N3), showed significant superiority in most vegetative growth traits; it gave the highest increase in leaves, the number of 65.28 leaves.transplant-1 , highest leaves nitrogen content of 1.56%, phosphorous 0.32%. The addition of these bacteria did not significantly affect the increase in stem diameter and leaf area. Rootstocks varied among themselves in vegetative growth characteristics and leaf minerals content, as Rangpur rootstocks (R2) excelled in increasing the stem diameter of 2.32 mm and the leaves number of 83.90 leaves.transplant-1 . In contrast, sour orange rootstock (R1) was superior in increased leaf area of 21.49 cm2 and leaves phosphors content of 0.30%. In contrast, C-35 rootstock (R3) outperformed in leaves nitrogen content by 1.44%. Twice and triple interactions between the study factors significantly affected all studied vegetative growth traits and leaf mineral content.

The Vulnerable Indian Roofed Turtle Pangshura tecta (Gray, 1831) (Testudines: Geoemydidae) occurs in the Sub-Himalayan lowlands of India, Nepal, Bangladesh, and Pakistan. Little is known about its natural history, no studies have been conducted revealing its natural predators. In this study, a group of Large-billed Crow Corvus macrorhynchos Wagler, 1827 (Passeriformes: Corvidae) was observed hunting and predating on an Indian Roofed Turtle carcass in the bank of river Kuakhai, Bhubaneswar, India. The first record of this predation behaviour is reported and substantiated by photographic evidence.
Abstract
This Research aims for harnessing critical and innovative thinking approaches besides innovative problem solving tools in pursuing continual quality improvement initiatives for the benefit of achieving operations results effectively in water treatment plants in Baghdad Water Authority. Case study has been used in fulfilling this research in the sadr city water treatment plant, which was chosen as a study sample as it facilitates describing and analyzing its current operational situation, collecting and analyzing its own data, in order to get its own desired improvement opportunity be done. Many statistical means and visual thinking promoting methods has been used to fulfill research task.
... Show MoreThe gas sensing properties of Co3O4and Co3O4:Y nano structures were investigated. The films were synthesized using the hydrothermal method on a seeded layer. The XRD, SEM analysis and gas sensing properties were investigated for Co3O4and Co3O4:Y thin films. XRD analysis shows that all films are polycrystalline in nature, having a cubic structure, and the crystallite size is (11.7)nm for cobalt oxide and (9.3)nm for the Co3O4:10%Y. The SEM analysis of thin films obviously indicates that Co3O4possesses a nanosphere-like structure and a flower-like structure for Co3O4:Y.The sensitivity, response time and recovery time to a H2S reducing gas were tested at different operating
... Show MoreThe study sought to identify the attitudes of PhD students towards establishing the field of educational administration. The study followed the descriptive survey method. The questionnaire was used to collect information from the study community consisting of (95) male and female students in the department of educational administration and Planning. Among the most important results about students ’attitudes towards establishing the educational administration field are the following: 1) identifying the necessity of establishing the educational administration field. 2) Encouraging students to attend seminars and scientific conferences in Islamic rooting. 3) there are no statistically significant differences in the attitudes of doctoral s
... Show MoreThe emergence of COVID-19 has resulted in an unprecedented escalation in different aspects of human activities, including medical education. Students and educators across academic institutions have confronted various challenges in following the guidelines of protection against the disease on one hand and accomplishing learning curricula on the other hand. In this short view, we presented our experience in implementing e-learning to the undergraduate nursing students during the present COVID-19 pandemic emphasizing the learning content, barriers, and feedback of students and educators. We hope that this view will trigger the preparedness of nursing faculties in Iraq to deal with this new modality of learning and improve it should t
