Fast Fourier Transform (FFT) processors employed with pipeline architecture consist of series of Processing Elements (PE) or Butterfly Units (BU). BU or PE of FFT performs multiplication and addition on complex numbers. This paper proposes a single BU to compute radix-2, 8 point FFT in the time domain as well as frequency domain by replacing a series of PEs. This BU comprises of fused floating ...

Objective Busulfan (BU) has a destructive effect on the male reproductive system. On the one hand, traditional herbs such as olive leaf extract (OLE) have been considered as sources of antioxidants and phenolic compounds. The goal of this study was to assess the effects of OLE on BU-induced damages in rat testes. MaterialsAndMethods In this experimental study, 40 male Wistar rats divided random...

electronic effects were investigated on the singlet–triplet energy gaps of divalent unsaturated seven- membered ring r2c6h6m (m=c, si, ge, sn, pb, r= –h, -ch3, i-pr , t-bu) at b3lyp/6-311++g** level. all the triplet states of r2c6h6c were more stable than the related the singlet states while all the singlet states of r2c6h6m (m= si, ge, sn, pb, r= –h, -ch3, i-pr , t-bu) were more stable than th...

The 1, 3-bis(trimethyl silyl)ether of p-tert-butyl calix[4]arene, Rt-Bu)Ca1ixTMS21112, has beensynthesized and used as a dianionic ligand for "Sn". The complex of [(t-Bu)Ca1ixTMS2]Snexhibits exo and endo isomerism. The structural properties of [(Rp)Ca1ixTMS2]Sn, (Rpara= H,CH3, t-Bu) and the inter conversion of exoendo isomers were investigated by using of SCF-MOPM3 method.

Background Autopsies can provide a good indication of the quality of patient care, in terms of the accuracy of clinical diagnosis and the quality of treatment given. Designs This was a cross-sectional study among clinicians at the Korle-Bu Teaching Hospital (KBTH) in 2012. Data were collected with a 69-item, self-administered, structured questionnaire. A total of 215 questionnaires were sent ou...
