A solar-powered vending cart was designed and developed for storage of fruits and vegetables. It was tested for its performance during summer season. The minimum and maximum drop in temperature ranged between 8.1°C and 11.2°C, and the increase in relative humidity was observed to be up to 15% and 25% inside the vending card chamber in June. The requirement of water ranged between 16.5 and 20.0 litre/day. There was considerable effect on physiological loss in weight of different vegetables kept either inside or outside the mobile chamber. The freshness and shelflife of vegetables increased substantially after storage in the cart.Keywords

Preserving fruits and vegetables in cold storage has been a critical area of concern because at low temperature, these perishable commodities can be preserved in their wholesome state for longer periods. However, the absence of cold storage facilities to accommodate the ever-increasing supply of fruits and vegetables has compelled the producers to adopt alternative storage practices; practices that in effect would preferably be economical than renting space in cold store and more efficient than rustic storage producers.Full Text

India has a vast potential of solar energy availability for about 300 sunny days in a year. It has an estimated potential of solar energy of approximately 5 x 1015 kWh/yr, which is far more than the total energy consumption of the country. Even a part of this, if appropriately harnessed, will be able to meet a sizable portion of the demand. The daily average incident solar energy varies from 4 to 7 kWh/m2 depending on the location.Full Text

The world energy crisis has now given importance to solar energy utilization, research and development programmes all over the world. The sun is the largest fusion reactor known to mankind which supplies about 1000 times more energy than we need each day in the form of electromagnetic radiations. In order to harness solar energy, a dark surface is exposed to solar radiation so that it is absorbed1. Two main approaches currently in use to harness solar energy are converting it to electricity by photovoltaic approach and converting it to thermal energy by solar thermal conversion. The simplest and most efficient way to utilize solar energy is to convert it into thermal energy for heating applications. The economic feasibility of solar energy utilization depends upon its efficient collection, conservation and storage. The efficient utilization of solar energy for heating, cooling and process applications requires the use of flat-plate or even focusing collector systems which first receive, as much as possible, the incoming solar radiation and then deliver a large fraction of the thermal energy to the working fluid2. The flat-plate collector is the key component of any solar energy system.Full Text

latest International Reference Ionosphere (IRI) versions (viz. IRI-2007, IRI-2012 and IRI-2016) with TEC derived by the International GNSS Service (IGS) receivers at a low-latitude station, namely Pathum Wan, Thailand (code-CUSV; lat. 13.74°N, long. 100.54°E) during the twin solar maxima 2012 and 2014, and the solar minima 2017 of the 24th solar cycle. We observed that the modelled TEC results were slightly underestimated than those derived by global positioning system (GPS), during the maxima and minima periods. It was also observed that the modelled TEC and GPS TEC followed a similar sinusoidal pattern with crests in the equinox months and troughs in the solstice months. We calculated standard deviation of the modelled TEC from the corresponding GPS TEC during the period. The study shows that the IRI model is more suitable when applied during solar minima period. We also carried out correlation study between modelled TEC and GPS TEC, and obtained a moderate degree of positive correlation. Thus we can conclude that IRI-2007 is the most suitable version for the twin solar maxima and the minima periods. Also IRI-2016 is the most suitable model for TEC estimation during geomagnetic storms.Keywords
