This experiment was carried out to increase the shelf life and maintaining the quality of mango (Mangifera indica) fruits. There were two factors. Factor A: postharvest treatments with six levels (1. untreated (control), 2. washing with chlorine, 3. dipping (5 minutes) in calcium chloride (CaCl2), 4. dipping (5 minutes) in bavistin and rinse in clean water, 5. hot water treatment and 6. tap wat...

To obtain the eigenmodes of the electromagnetic field at a periodically corrugated metamaterial we consider a theory of spoof plasmons propagating on metamaterial perforated with planar periodic grooves. We present the rigorous modeling and analysis of surface waves at the boundary of the corrugated metamaterial structure. Particularly, we pay special attention to the ways of controlling the pr...

One way to increase the heat transfer is to use perforated twisted tapes with different hole diameters, which largely improve heat transfer with an increase in the heat transfer area at the constant volume and more mixed flow. In the previous studies, the effect of nanofluids with perforated twisted tapes is less studied. In this work, the performance of water / iron oxide nanofluid in a double...

In this study, we tested for the presence and efÞcacy of hygienic behavior by Cape honey bees in South Africa and European honey bees, Apis mellifera L. (Hymenoptera: Apidae), of mixed origin in the United States toward Aethina tumida Murray (Coleoptera: Nitidulidae) eggs oviposited in sealed bee brood. We looked for colony differences in removal rates of brood in cells with cappings perforated...

The indispensable vital structure in any harbor is a breakwater in order to make available calm water region inshore. Pile breakwater can be employed as a small coastal protection structure where tranquility required is low. This study is concerned with CFD study on the performance of perforated hollow pile to dissipate wave energy and the novelty of this investigation is the role of perforatio...

The self-assembly of sphere-forming triblock copolymers confined between two thin homogeneous surfaces is investigated based on mean-field dynamic density functional theory. The morphologies deviating from the bulk sphere-forming phase are revealed, including cylinders oriented perpendicular to the surface, cylinders oriented parallel to the surface, perforated lamellae and lamellae by varying ...

Transmission spectra of metallic films or membranes perforated by arrays of subwavelength slits or holes have been widely interpreted as resonance absorption by surface plasmon polaritons. Alternative interpretations involving evanescent waves diffracted on the surface have also been proposed. These two approaches lead to divergent predictions for some surface wave properties. Using far-field i...

A fully coupled numerical model is developed to study wave interactions with perforated elastic disks. The flow past the surface represented by a quadratic pressure discharge condition practical validity. nonlinear nature of drop results in dependency hydrodynamic responses on steepness.

To minimize unwanted noise, the exhaust gas of high pressure and high temperature coming out of internal combustion engine passes through silencer. Various types of silencers like absorptive, reactive and resonating, perforated type are widely implemented in actual practice .perforated reactive mufflers have an effective damping capability. This paper deals with comparative structural analysis ...
