objective(s): over the past two decades, considerable interest has been focused on utilizing biocompatible magnetic nanoparticles (mnps) for biomedical applications. in this study, production of human serum albumin (hsa) nanoparticles using desolvation technique that were simultaneous loaded with high amounts of superparamagnetic iron oxide nanoparticles (spions) and 5-flourouracil (5-fu) was i...

Introduction: Due to limitations of current treatments for degenerative disc disease, arthroplastic methods to repair the diseased disc have been proposed. The artificial disc is a mobile implant for degenerative disc replacement that attempts to lessen the degeneration of the adjacent elements following interbody fusion procedures. Because the success of artificial disc replacement depends on ...

in some conditions, to avoid deterioration and field losses of soybean seeds (glycine max merr.) from weathering at end of the season, farmers start to harvest seeds with a high moisture content and so, careful post-harvest drying would be required to maintain the physiological quality of seeds. response surface methodology (rsm) was used to optimize the operating conditions of soybean seed dry...

Transparent speech quality has not been achieved at low bit rates, especially at 2.4 kbps and below, which is an area of interest for military and security applications. In this paper, strategies for low bit rate sinusoidal coding are discussed. Previous work in the literature on using metaframes and performing variable bit allocation according to the metaframe type is extended. An optimum meta...

A variable bit rate multiband excited linear predictive speech coder is proposed in this paper. Speech signal is compressed in different bit rates ranging from 0.88 kbps to 2.6 kbps according to the mode of operation and the optimum V/UV transition frequency. An average bit rate of 1.24 kbps is achieved. The proposed speech coder improves the speech quality by splitting the non-stationary speec...

In this paper Bit Error Rate performance of QPSK modulation and OFDM -QPSK System over AWGN and Rayleigh fading channel is analyzed. The performance of BER of QPSK over AWGN and Rayleigh channel is compared. OFDM is an orthogonal frequency division multiplexing to reduce intersymbol interference problem. Simulation of QPSK signals is carried with both AWGN and Rayleigh channel. Finally simulati...

We demonstrate a small foot print (600 nm wide) 1D silicon photonic crystal electro-optic modulator operating with only a 50 mV swing voltage and 0.1 fJ/bit switching energy at GHz speeds, which are the lowest values ever reported for a silicon electro-optic modulator. A 3 dB extinction ratio is demonstrated with an ultra-low 50 mV swing voltage with a total device energy consumption of 42.8 fJ...
