Field experiments were carried out for the autumn season 2022- 2021 in the field of College of Agricultural Engineering Sciences - University of Baghdad - Jadiriyah Complex –Station A- to study a combination of organic fertilizer (Vermicompost) and cow manure as well as a control treatment (soil only) intertwined with Spraying with silicon, calcium and distilled water (control) in the growth and production of three cultivars of beet (Cylindra, Dark Red, Red) within the design of Completely Randomized Block Design at three replications, The number of treatments was 9 for each replicate. The means were compared according to the least significant difference (L.S.D) at a probability level of 5 %, the results were as follows:-The interaction treatment of the Vermicompost with calcium spraying in the number of leaves, the concentration of chlorophyll, the percentage of nitrogen and phosphorous), was significantly superior to the combination of Vermicompost with spraying silicon significantly (in the percentage of potassium, the concentration of silicon, the root yield, the leaf yield, the percentage of dry matter, phenols and sugars), at a rate of (387.67,3%.28 mg kg−1, 35.88 ton h−1, 50 ton h−1, 8.78%, 014% and 889%) respectively. As for the percentage of calcium, it was characterized by the combination treatment of cow manure with calcium spray, and the combination of cow manure with silicon spray was superior in T.S.S. and the percentage of fiber at 3.17 and 11.66% respectively for the Red variety.As for the variety Red Dark it was significantly superior to the mixture of the medium vericompost with silicon spray in the number of leaves, the concentration of chlorophyll and the percentage of nitrogen, the concentration of silicon, Root yield and leaf yield Percentage of dry matter T.S.S, phenols and sugars at (10 leaf plant−1, 82.2 mg 100 fresh wet−1, 3.53%, 313.00 mg kg−1, 36.35 ton h−1, 40.92 ton h−1, 6.86%, 11.03%, 0.16% and 845%) respectively, while the percentage of phosphorous and potassium, it was characterized by the combination of cow manure with silicon spray, and the combination of vermicompost with calcium spray was superior to the percentage of calcium and the percentage of fiber by giving it 2.19% and 2.50% respectively. As for the variety Cylindra it was significantly superior to the combination of the Vericompost with silicon spray in the number of leaves, concentration of chlorophyll, percentage of nitrogen, phosphorous, silicon, root yield, leaf yield, Percentage of dry matter, T.S.S, Whereas, the treatment with cow manure overlapping with silicon was superior in the percentage of potassium, phenols and sugars, as it gave 4.11% 0.13 and 665% respectively, The treatment of the Vermicompost with calcium spray was characterized in the percentage of calcium as it gave 1.65%.
This study is conducted to determine the effect of pathogenicity of the fungus Lecanicillium lecanii in some aspects of life of the insect saw toothed beetle Oryzaephilus surinamensis L. (Coleoptera: Silvanidae) under laboratory conditions with three concentrations of spores and mildew commentator (1 × 103, 1 × 105, 1 × 107) spore / ml , on eggs and larvae second phase of the insect .The study also includs the effect of the fungus concentrations of germination on rice (jasmine) by using direct spray treatment. The results show great fungus efficiency in the control of some aspects of life of the insect, where varied efficiency depends on the concentration of spores, The highest percentage loss of eggs is 63.33% at a concentration
... Show MoreThe catalytic cracking of three feeds of extract lubricating oil, that produced as a by-product from the process of furfural extraction of lubricating oil base stock in AL-Dura refinery at different operating condition, were carried out at a fixed bed laboratory reactor. The initial boiling point for these feeds was 140 ºC for sample (1), 86 ºC for sample (2) and 80 ºC for sample (3). The catalytic cracking processes were carried out at temperature range 325-400 ºC and initially at atmospheric pressure after 30 minutes over 9.88 % HY-zeolite catalyst load. The comparison between the conversion at different operating conditions of catalytic cracking processes indicates that a high yield was obtained at 375°C, according to gasoline pr

Early detection of eye diseases can forestall visual deficiency and vision loss. There are several types of human eye diseases, for example, diabetic retinopathy, glaucoma, arteriosclerosis, and hypertension. Diabetic retinopathy (DR) which is brought about by diabetes causes the retinal vessels harmed and blood leakage in the retina. Retinal blood vessels have a huge job in the detection and treatment of different retinal diseases. Thus, retinal vasculature extraction is significant to help experts for the finding and treatment of systematic diseases. Accordingly, early detection and consequent treatment are fundamental for influenced patients to protect their vision. The aim of this paper is to detect blood vessels from
... Show MoreA new efficient Two Derivative Runge-Kutta method (TDRK) of order five is developed for the numerical solution of the special first order ordinary differential equations (ODEs). The new method is derived using the property of First Same As Last (FSAL). We analyzed the stability of our method. The numerical results are presented to illustrate the efficiency of the new method in comparison with some well-known RK methods.
Single Point Incremental Forming (SPIF) is a forming technique of sheet material based on layered manufacturing principles. The sheet part is locally deformed through horizontal slices. The moving locus of forming tool (called as toolpath) in these slices constructed to the finished part was performed by the CNC technology. The toolpath was created directly from CAD model of final product. The forming tool is a Ball-end forming tool, which was moved along the toolpath while the edges of sheet material were clamped rigidly on fixture.
This paper presented an investigation study of thinning distribution of a conical shapes carried out by incremental forming and the validation of finite element method to evaluate the limits of the p
... Show MoreMass transfer has been studied at rotating cylinder electrodes fabricated with spiral-wound woven-wire meshes using reduction of copper as a test reaction. The experimental data were correlated by an empirical expression between the Sherwood number and the Reynolds number, both regarding the hydraulic diameter as a characteristic length. It was found that the Sherwood number was dependent upon the Reynolds number to the power of 0.521. An enhancement factor was adopted to compare the efficiency of the new rotating cylinder electrode with previous three-dimensional rotating cylinder electrodes. The results showed that the new type has a mass-transfer enhancement factor 2.3 times higher than those obtained with smooth rotating cylinder electr
