The purpose of this review was to evaluate the current role of multiparametric magnetic resonance imaging (mp-MRI) in the managementof prostate cancer (PC). The diagnosis of PC remains controversial owing to overdetection of indolent disease, whichleads to overtreatment and subsequent patient harm. mp-MRI has the potential to equilibrate the imbalance between detectionand treatment. The limitation of the data for analysis with this new technology is problematic, however. This issue has been compoundedby a paradigm shift in clinical practice aimed at utilizing this modality, which has been rolled out in an ad hoc fashionoften with commercial motivation. Despite a growing body of literature, pertinent clinical questions remain. For example, can mp-MRI be calibrated to reliably detect biologically significant disease? As with any new technology, objective evaluation of the clinicalapplications of mp-MRI is essential. The focus of this review was on the evaluation of mp-MRI of the prostate with respect to clinicalutility.

Grewia serrulata fibres were chemically treated with 3%, 6%, and 9% NaOH for the duration of 4 h. Additionally, the NaOH-treated fibres were also treated with 3 - (trimethoxysilyl) propyl methacrylate (silane). Properties such as density and tensile strength of the treated fibres were compared against the untreated fibres. The highest density was obtained in the case of 9% NaOH + silane treated fibres, which was 26.47% higher than untreated fibres, implying effective removal of hemicellulose. Likewise, the highest tensile strength was also obtained in the case of 9% NaOH + silane treated fibres. The increment observed in the tensile strength of the natural fibres was related to the removal of impurities, hemicellulose, and stress-raisers as well as deposition over the fibre surface that smoothed it. These observations were further validated by estimating changes in chemical constituents due to chemical treatment along with characterization techniques such as scanning electron microscopy and thermogravimetric analysis.

CdTe based solar cells with high effi ciency alternative to solar cells from elemental semiconductors is an important work carried out over the decades. However, the research has not yet yielded the highest possible effi ciency with CdTe absorber. Selection of suitable window layer and optimizing the thickness of the diff erent layers is still a quest in researchers. Numerical simulation of the diff erent material combinations can speed up the research work. In this regard, numerical simulation is an essential tool to fi nd the optimized structure for the enhanced device performance. In the present work, the thicknesses of window and absorber layers, one of the crucial factors that aff ect the solar cell performance, are tuned for ZnO/CdS/CdTe system. In case of CdS/CdTe solar cells, spectral loss created by CdS lowers the cell effi ciency. Concept of bilayer window is useful to minimize the loss at window layer. Hence the ZnO/CdS bilayer window is adopted and demonstrated that the cell effi ciency can be increased up to 17.66% with current density of 28.4 mA/cm 2 and 73.7% fi ll factor.
