The Australian National University has re-engineered its Big Dish design for commercialisation and mass production [1], building the 'SG4' 500m Big Dish solar paraboloidal concentrator for solar-thermal to electric energy conversion using direct-steam generation. The SG4 Dish implements two-axis tracking and may be incorporated into a dish-array for large-scale power production. A program has b...

This paper deals with the improved model(Two Diode Model) of solar photovoltaic (SPV) module and back propagation neural network based maximum power point tracking (MPPT) for boost converter in a standalone photovoltaic system under variable temperature and insolation conditions. ie. The proposed model is robust to environment changes and load variations. Unlike Conventional solar-array mathema...

This paper presents sizing, energy management strategy, and cost analysis for a configuration consisting of solar photovoltaic (PV) panels, fuel cell (FC) storage system, and reverse osmosis (RO) desalination technology for combined power and fresh water production. In this system, PV is the main power supply source; fuel cell is a storage system accompanied by Hydrogen production and storage d...

The positioning of In0.8Ga0.2As quantum dots (QDs) array in the i-region solar cell (SC) on its photogenerated current and dark saturation currents, which determine operating voltage device, have been investigated. It was found that indicated photoelectric characteristics depend location QD relative to electric field p-n junction. displacement boundary weakly doped base leads a decrease current...

Maximization of power from a solar photovoltaic (PV) module is of special interest as the efficiency of the solar PV system is very low. A maximum power point tracker (MPPT) is needed to operate the PV array at its maximum power point. The present work describes the design and implementation of a MPPT for the solar PV array connected to a resistive load. The design consists of a dc-dc boost con...

Objective(s): The OCT4B1, as one of OCT4 variants, is expressed in cancer cell lines and tissues more than other variants and plays an important role in apoptosis and stress (heat shock protein) pathways. The present study was designed to determine the effects of OCT4B1 silencing on expressional profile of HSP40 gene family expression in three different human tumor cell lines. Materials and Met...

Background: OCT4B1, a variant of OCT4, is expressed in both cancer cells and tissues. This variant has a main role in the regulation of both apoptotic and stress (heat-shock proteins) pathways. The aim of this study was to investigate the effects of OCT4B1 silencing on the expression of small heat-shock proteins (sHSPs)in three human tumor cell lines. Methods:...

For several years the only experiments sensitive to astrophysical gamma rays with energies beyond the reach of EGRET but below that of the Cherenkov imaging telescopes have been the ”solar tower” detectors. They use > 2000 m mirror areas to sample the Cherenkov wavefront generated by < 100 GeV gamma rays, obtaining Crab sensitivities of more than 6σ in one ON-source hour. I will review the hist...
