An Economic Study Of The Repercussions Of The Wheat Gap In The Arab Republic Of Egypt

Despite an increase in wheat-farmed area and, as a result, an increase in total wheat crop yield. Because of the annual population increase, the consumed quantities of it continue to rise at rates faster than the rates of expanded production. As a result, the nutritional gap in wheat has widened and the sufficiency ratio has decreased. As a result, the study's primary goal is to investigate and estimate the most relevant indicators of food security for Egypt's wheat crop, which is one of the country's most essential strategic crops, during the study period (2001-2020). To achieve the research's goals, it relied heavily on descriptive and quantitative data analysis, including the employment of a linear regression model of the general trend equations to calculate the annual growth rate of the study variables' evolution. When the food gap for Egypt's wheat harvest was calculated, it was discovered to have a general increasing tendency, with an annual increase rate of roughly 5.2%. The annual percentage of wheat self-sufficiency, with an annual growth rate of roughly 1.3%. It also revealed a decline in the value of the wheat crop's food security coefficient, which was around 0.26. The drop is attributable to a greater reliance on imports to meet the essential needs, as well as a reduction in strategic stock. As a result, in order to increase the area of wheat, the value of the food security coefficient must be increased, as well as horizontal expansion. Taking a variety of agricultural strategies and growth plans into consideration

Investigation of Inhibition Effect of Acrylic acid on C-Steel Corrosion in Sulfuric Acid Solutions

Acrylic acid was tested as a corrosion inhibitor for C-steel in 0.5 M H2SO4 using gasometry, weight loss, and galvanostatic polarization techniques. Polymeric film is built up by cyclic voltammetry technique. The potentiodynamic polarization is used to examine the inhibition effect with the coated polymeric film. The data obtained from the different techniques coincide in that acrylic acid is a good mixed-type inhibitor. The inhibition process is based on the adsorption of acrylic acid on the surface of C-steel according to Temkin’s adsorption isotherm. The inhibition efficiency increases with inhibitor concentration and decreases with temperature. The thermodynamic parameters ΔE, ΔH*, ΔS*, and ΔG*ads were calculated to elaborate the mechanism of corrosion inhibition

A new swarm intelligence information technique for improving information balancedness on the skin lesions segmentation

Methods of image processing can recognize the images of melanoma lesions border in addition to the disease compared to a skilled dermatologist. New swarm intelligence technique depends on meta-heuristic that is industrialized to resolve composite real problems which are problematic to explain by the available deterministic approaches. For an accurate detection of all segmentation and classification of skin lesions, some dealings should be measured which contain, contrast broadening, irregularity quantity, choice of most optimal features, and so into the world. The price essential for the action of progressive disease cases is identical high and the survival percentage is low. Many electronic dermoscopy classifications are advanced depend on the grouping of form, surface and dye features to facilitate premature analysis of malignance. To overcome this problematic, an effective prototypical for accurate boundary detection and arrangement is obtainable. The projected classical recovers the optimization segment of accuracy in its pre-processing stage, applying contrast improvement of lesion area compared to the contextual. In conclusion, optimized features are future fed into of artifical bee colony (ABC) segmentation. Wide-ranging researches have been supported out on four databases named as, ISBI (2016, 2017, 2018) and PH2. Also, the selection technique outclasses and successfully indifferent the dismissed features. The paper shows a different process for lesions optimal segmentation that could be functional to a variation of images with changed possessions and insufficiencies is planned with multistep pre-processing stage

Cornelia-de Lange syndrome in an Egyptian infant with unusual bone deformities

AbstractWe report a 4month old female infant with the typical features of Cornelia-de Lange syndrome. What was striking in our patient was the presence of skeletal anomalies not reported previously. These included arachnodactly of both fingers and toes, flexion of thumbs at metacarpophalengeal joints, bilateral short big toes, angulation of the lower part of the bones of right forearm and both legs with multiple skin folds. Also biochemical and X-ray evidence of rickets was detected mostly due to malnutrition and failure to thrive. The patient died at the age of 5months with bronchopneumonia and gastroenteritis

Trichorhinophalangeal syndrome II, expanding the clinical spectrum

AbstractWe report a 4.5year old Egyptian male child, fourth in the order of birth of healthy remote consanguineous parents. He has typical facial as well as skeletal features of Trichorhinophalangeal syndrome (TRPS) II. The facial features included bilateral downward slanting palpebral fissures, bulbous nose, long filtrum, retromicrognathia, sparse hair in the scalp and thick eyebrows. The skeletal features included retarded bone age, cone shaped epiphyses of the phalanges and multiple exostoses. The patient has also growth retardation, moderate mental retardation and hyperlaxity of the right knee joint. However our patient has some features not reported in TRPS II patients. These included bilateral partial ptosis, long eye lashes, preauricular skin tag, short 2nd right finger, short metacarpals of both thumbs. So we have to expand the clinical spectrum. Karyotype demonstrated 46,XY,del 8(q23.3-q24.1)

The experimental result shows the average thermal efficiency was 42% which is fairly acceptable assessment results of a PTSC locally

Assessing Drought Tolerance of Newly Developed Tissue-Cultured Canola Genotypes under Varying Irrigation Regimes

This article belongs to the Special Issue Crop Tolerance under Biotic and Abiotic Stresses[Abstract] Drought is a major abiotic stress that greatly affects canola growth, production, and quality. Moreover, water scarcity is projected to be more severe and frequent as a result of climate change, in particular in arid environments. Thereupon, developing drought-tolerant and high-yielding canola genotypes has become more critical to sustaining its production and ensuring global food security with the continuing population growth. In the present study, ten canola genotypes comprising six developed tissue-cultured canola genotypes, two exotic genotypes, and two commercial cultivars were evaluated under four irrigation regimes. The applied irrigation regimes were well-watered (100% crop evapotranspiration, ETc), mild drought (80% ETc), moderate drought (60% ETc), and severe drought (40% ETc) conditions. Drought-stress treatments (80, 60, and 40% ETc) gradually reduced the chlorophyll content, relative water content, flowering time, days to maturity, plant height, number of pods, number of branches, seed yield, and oil percentage, and increased proline, phenolic, anthocyanin, and glycine betaine contents. The evaluated genotypes exhibited varied responses to drought-stress conditions. The developed tissue-cultured genotypes T2, T3, and T1, as well as exotic genotype Torpe, possessed the highest performance in all evaluated parameters and surpassed the other tested genotypes under water-deficit conditions. Overall, our findings elicited the superiority of certain newly developed tissue-cultured genotypes and exotic ones compared with commercial cultivars, which could be exploited in canola breeding under water-deficit conditions.This research was funded by the Researchers Supporting Project number (RSPD-2023R730), King Saud University, Riyadh, Saudi ArabiaKing Saud University (Riad, Arabia Saudí); RSPD-2023R73
