Classification of Apple Tree Leaves Diseases using Deep Learning Methods
Alsayed, Ashwaq,Alsabei, Amani,Arif, Muhammad International Journal of Computer ScienceNetwork S 2021 International journal of computer science and netw Vol.21 No.7
Agriculture is one of the essential needs of human life on planet Earth. It is the source of food and earnings for many individuals around the world. The economy of many countries is associated with the agriculture sector. Lots of diseases exist that attack various fruits and crops. Apple Tree Leaves also suffer different types of pathological conditions that affect their production. These pathological conditions include apple scab, cedar apple rust, or multiple diseases, etc. In this paper, an automatic detection framework based on deep learning is investigated for apple leaves disease classification. Different pre-trained models, VGG16, ResNetV2, InceptionV3, and MobileNetV2, are considered for transfer learning. A combination of parameters like learning rate, batch size, and optimizer is analyzed, and the best combination of ResNetV2 with Adam optimizer provided the best classification accuracy of 94%.

Purpose: Autoimmune hepatitis (AIH) is a chronic disease that may lead to cirrhosis. The immunopathogenesis of AIH is not fully understood and it mainly involves T-cell mediated mechanism. Macrophage migration inhibitory factor (MIF) is a pro-inflammatory cytokine that promotes T cell response and its polymorphism may serve as a severity marker of AIH. No previous study has considered investigating MIF polymorphism in children with AIH. Methods: Forty-two children with definite diagnosis of AIH were enrolled along with 100 age and sex matched controls. All participants were tested for polymorphism at -173GC (rs755622) of MIF gene. All patients received the standard protocol of steroid plus azathioprine to achieve remission. Liver biopsy was performed at time of diagnosis for all patients and only 18 of them underwent a second biopsy after treatment. Results: No statistically significant differences in the frequency of the genotypes GG and GC or in allele distribution were found in both patient and control groups (p=0.590, 0.640 respectively). Initial alanine aminotransferase (ALT) levels at the time of presentation was significantly higher in the GC group than GG group (p=0.020). GC genotype significantly correlated with disease relapse (r=0.41, p=0.007). Regression of necroinflammation and the fibrosis score in the second liver biopsy was statistically significant in the GG group (p<0.0001, p=0.010 respectively). Conclusion: MIF -173GC polymorphism is associated with clinically significant markers of pediatric AIH, including increased initial serum ALT levels, may help predict necroinflammatory/fibrosis regression effectively, following immunosuppressive treatment.

By the hydrolysis of lipid-rich substrates in anaerobic digestion (AD) process, long chain fatty acids (LCFAs) are excreted, which are known to adversely affect further degradation steps and limit methane productivity. On the other hand, direct interspecies electron transfer (DIET) reaction could make syntrophic degradation of LCFAs thermodynamically favorable. In the present work, anaerobic batch tests were performed while supplementing conductive materials, carbon nanotube (CNT) or magnetite powder (Fe3O4), at different concentrations of oleic acid (1, 2, 4, 6 and 8 g COD/L). The maximal volumetric CH4 production values of 0.41 and 0.64 L CH4/L reactor, recording 84 and 188% higher than control, were found at batch of 4 g COD/L, were corresponding to Fe3O4 and CNT, respectively. At all the tested concentrations of oleic acid, supplementation of either CNT or Fe3O4 remarkably reduced the needed lag phase period. The reason behind advanced CH4 production attitude denoted by CNT compared to Fe3O4 can be the high specific surface area, which provides an advanced microbial attachment feature. Further, Fe3O4- and CNT-supplemented consortia exhibited enhanced conductivity values of 15.7 and 12.4 μS/cm, comapred to the 8.1 μS/cm found in control. This study concludes the feasibility of supplementing conductive materials, especially CNT, for mitigating the inhibitory impact of LCFA digestion and boosting the attained CH4 production.
