High tunnels can provide several benefits to horticultural crops, including environmental stress protection such as hail, frost, excessive rainfall, and high wind. In hot and sunny areas, high tunnel is one of the cooling ways for modifying the microclimate and maximizing crop development. Present study was carried out to assess the effect of different type of high tunnels on banana growth, yield, and fruit quality characteristics. Net houses, poly net houses, UV poly shed houses, and open field (control) conditions are among the experimental treatments. The results revealed that the plants produced in the poly net house condition had maximum pseudo stem height (171.00cm), stem girth (68.66 cm), chlorophyll content (57.63), number of fruits (140), number of hands (9.66), individual fruit weight (125.00) and pulp: peel ratio (3.35) of bananas as compared to the other treatments. Quality parameters like total soluble solid (21.78°Brix), ascorbic acid (10.24 mg/100g), total sugar (25.44%), and reducing sugar (15.75%) were higher in fruits grown in poly net house.

Diabetic macular edema (DME) has become one of the most potential complications that results in loss of vision in patients with diabetic retinopathy. Treatment outcomes that have been predicted directly with advent of machine learning (ML) methods after the initial anti-vascular endothelial growth factor (anti-VEGF) injection, has become extremely vital in the management of DME. Purpose: The aim of this study is to analyze the efficiency of the ML regression models which were developed and validated to predict the possible post-injection central subfield thickness (CST) value and distant vision best corrected visual acuity (DV BCVA) in eyes with DME before the anti-VEGF injection is administered at either treatment initiation or during treatment monitoring. Methods: This retrospective study was conducted in Medical Research Foundation, Chennai, India from January 2010 to December 2020. The model development emphasized on an ensemble ML system consisting of four ML models that were developed and trained independently using the clinical parameters to predict the post injection CST value. The dataset consisting of 906 patients with total of 1874 samples [Optical coherence tomography (OCT) images and clinical parameters] were divided into trained and test set, and the model was validated on test dataset. The predicted CST values was then compared against the respective sample’s post injection actual CST value. The comparative results were measured in terms of Correlation Coefficient and Mean Absolute Relative Error (MARE). Results: On evaluation, we found that Support Vector Regression (SVR) with linear kernel performed best among the other models with four different scenarios in term of both CST and DVBCVA prediction with correlation coefficient of 0.65, 0.73, 0.75, 0.85 and 0.83, 0.87, 0.89 and 0.92 respectively.

In this paper, we take a creative look at the effect of cracking on the buckling of graphene sheets. We introduced a significant improvement in molecular mechanical calculations that more accurately examine the behavior of atomic bonds during the instability of nanostructures in the presence of defects. A molecular mechanics method based on the modified couple stress (MCS) theory to consider the size effect on the graphene plate is introduced. Primary cracks with different lengths, orientations, and numbers were examined. For each crack, buckling parameters such as critical load and buckling modes of graphene sheets were investigated. This model has better computational performance and less computational compactness than other models. Our studies show that cracks perpendicular to the load direction have a greater effect on buckling parameters, including modes and critical buckling load than cracks aligned to the critical load. Increasing the crack length will further reduce the critical buckling load. The effect of the number of cracks in two directions in buckling parameters was investigated. Increasing the number of cracks always decreases a critical buckling load. Increasing the number of cracks affects the first buckling mode more than others. The study of the eccentricity of cracks shows that with increasing the eccentricity distance, in cracks perpendicular to the loading direction, the critical buckling load will be further reduced. However, for cracks aligned with the load direction, increasing the eccentric distance has less effect on reducing the critical buckling load.

Charles Bonnet syndrome (CBS) comprises of complex visual hallucinations secondary to visual impairment in the presence of preserved cognition. Age related macular degeneration and other factors causing visual deterioration lead to visual hallucinations in 10-15% of patients. Sensory deprivation and social isolation are risk factors for development of CBS. The distressing hallucinations are underreported by patients and to date there are no robust evidence based guidelines to manage these hallucinations. Since visual hallucinations are associated with multiple psychiatric disorders as well, these patients are often referred to mental health providers. Here, we present the case of CBS development after macular degeneration. Rapid and sustained resolution of visual hallucinations and associated distress was observed with low dose Risperidone.

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.
