Recent research has shown that listeners can hear anger and happiness from articulatorily synthesized vowels with body-size-related manipulations. In the present study we explore the possibility that direct manipulation of spectrum and F0 of naturally produced speech along the size dimension can also lead to perception of certain emotions. Ten English digits spoken in a neutral emotion by a nat...

Virtual reality has sometimes been thought of as embodying a return to a ‘natural’ way of interacting by direct manipulation of objects in a world. However, in the everyday world we also act through language: speaking is a ‘natural’ way of communicating our goals to others, and effecting changes in the world. In this paper, we discuss technical and design issues which need to be addressed in or...

Glycerol mono-oleate (GMO) was produced by direct esterification reaction with amberlyst 16 resin catalysts with the efficiency of 86% and was used as a surfactant for synthesis of CoFe2O4 nano-particles by surfactant-assisted microwave method. Fourier transform infrared spectroscopy (FT-IR), X-Ray diffraction (XRD) and scanning electron microscopy (SEM) were used to consider the structural and...

Palladium-catalyzed tandem multifunctional reactions leading to the synthesis of substituted biaryl molecules have been developed including tandem Heck-direct arylation and tandem-sequential Heck-direct arylation-hydrogenation. These reactions occur in good yield and have been employed in the synthesis of a cytotoxic biaryl compound.

We present here the first example of direct synthesis polyureas from dehydrogenative coupling diamines and methanol.

Hepatocytes derived either from rats fed a diet enriched in n-3 fatty acids or from rats fed a low-fat diet and cultured with an n-3 fatty acid (eicosapentaenoic acid, EPA) in vitro were used to distinguish between the dietary effects and the direct effects of n-3 fatty acids on hepatocellular apolipoprotein (apo) B metabolism and secretion. ApoB-48 and apoB-100 synthesis, degradation, and secr...

Phospho sulfonic acid (PSA) synthesized as an environmentally safe and efficient solid acid catalyst, and it used for the synthesis of several 2-disubstituted benzimidazoles, 2-substituted benzoxazoles, and 2-substituted quinoxalines in ethanol as a green solvent at ambient temperature is described. (i) A very simple, green and efficient procedure for the synthesis of benzimidazole and also benz...
