Title: Pre-storage Exogenous Application of Hydrogen Sulphide Reduces Sugar spot, Decay loss and Preserves Quality of Banana Fruit Authors: Su-Mon, Myat; Asrey, Ram; Prajapati, Uma Abstract: This research focuses on effect of hydrogen sulphide treatment (control, 0.5, 1.0, 1.5 mM) during ambient storage on sugar spot, decay loss and postharvest quality of banana fruit. Hydrogen sulphide (H₂S) treated fruit were stored at ambient conditions (25±2ºC and 60–65% of relative humidity) up to 9 days. In general, H₂S treatment maintained higher values of lightness, peel firmness, reduce the respiration rate and ethylene evolution rate and extended shelf life of stored fruit by delaying progression of ripening. Moreover, H2S (1.0 mM) was found significantly better over other treatments in reducing sugar spot or peel browning spot and maintaining the desirable overall postharvest traits of the fruit. The findings indicated that H₂S has a great potential for pre-storage application to preserve quality, reduce sugar spot and postharvest decay loss, possibly through the delayed onset of senescence, without any adverse effects on fruit quality.

Comparative Study of Physical Properties of Whole and Hulled Minor Millets for Equipment Designing

Sun, 01 Aug 2021 00:00:00 GMT

Title: Comparative Study of Physical Properties of Whole and Hulled Minor Millets for Equipment Designing Authors: Gaurav, Abhishek; Pradhan, Rama Chandra; Mishra, Sabyasachi Abstract: The present research was done for the selected minor millets viz. barnyard (Echinola esculenta), Kodo (Paspalum scrobiculatum), and little millets (Panicum sumatrense). The physical and engineering properties were evaluated at a moisture content of 10–11%, (dry basis) for whole and hulled millets. Significant improvement in the physical properties of the millets was observed for the hulled millets. The hulled millets showed higher sphericity (0.68–0.86) and exhibited a decrease in whole grains' spatial dimensions. The analysis (Gravimetric properties, frictional properties, Aerodynamic properties) was conducted for both whole and hulled millets. In frictional properties, mild steel surface showed the highest angle of static friction (9.78–17.96°) with smooth-rolling. The hulling has shown an improvement in all the physical and engineering properties of millets. In the color values, the whiteness index was improved for hulled millets. In the mechanical property of grains, resistance to crushing was expressed in terms of hardness. Page(s): 658-667

ANFIS Controlled Reactive Power Compensation Utilizing Grid-Connected Solar Photovoltaic System as PV-STATCOM

Sun, 01 Aug 2021 00:00:00 GMT

Title: ANFIS Controlled Reactive Power Compensation Utilizing Grid-Connected Solar Photovoltaic System as PV-STATCOM Authors: Gira, Naveen; Dahiya, Anil Kumar Abstract: This article proposes Adaptive Neuro Fuzzy Inference System (ANFIS) based control scheme for dual use of the grid connected solar photovoltaic (PV) system as the active power source when irradiance is high and as static compensator (STATCOM) for reactive power compensation to the grid when the irradiance level is inadequate. This way the strategy results in optimal utilization of the converter circuit of the solar PV. Thus, the dual use of solar PV system brings in additional advantages in terms of enhanced power transmission capability of the grid. To examine the efficacy of the proposed control strategy, the system is modeled and analysed in using MATLAB/Simulink tool and also validated over real-time simulator (OPAL-RT-OP5700).

Title: Enhanced Production of Tannase through RSM by Bacillus haynesii SSRY4 MN031245 under Submerged Fermentation Authors: Dhiman, Sunny; Mukherjee, Gunjan; Kumar, Anu; Majumdar, Rita Singh Abstract: Present investigation reports enhanced production of tannase by Bacillus haynesii SSRY4 MN031245 through application of Response Surface Methodology (RSM). Central Composite Design (CCD) of RSM was employed to determine the most important factors contributing to enzyme production and their interactions were analysed through graph models. Optimum production of enzyme (11.19 U/mL) was achieved at pH 5.5, temperature 37°C, incubation period 72 hours and agitation speed of 150.0 rpm. The statistically optimized values of variables enhanced the tannase production by 2.49 folds. Page(s): 675-680
