Palladium nanoparticles supported on multi-walled carbon nanotubes (Pd/MWCNTs) have been synthesized using a modified polyol reduction method and its performance in methanol oxidation reactions has evaluated. The morphology of palladium on MWCNTs was characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The catalytic performance of synthesized catalyst ...

The Haar wavelet collocation with iteration technique is applied for solving a class of time-fractional physical equations. The approximate solutions obtained by two dimensional Haar wavelet with iteration technique are compared with those obtained by analytical methods such as Adomian decomposition method (ADM) and variational iteration method (VIM). The results show that the present scheme is...

BACKGROUND Although the modified tension band technique (eg, tension band supplemented by longitudinal Kirschner wires) has long been the mainstay for fixation of transverse fractures of the patella, it has shortcomings, such as bad reduction, loosening of implants, and skin irritation. QUESTIONS/PURPOSES We conducted a retrospective comparison of the modified tension band technique and the t...

We present a theory of modified reduced dynamics in the presence counting fields. Reduced techniques are useful for describing open quantum systems at long emergent timescales when memory short. However, they can be difficult to formulate observables spanning system and its environment, such as those characterizing transport properties. A large variety mixed system--environment observables, wel...

Ventilation is essential to the health and comfort of occupants in enclosed spaces. However, it is difficult to accurately measure the ventilation rates in large, long, and narrow spaces such as aircraft cabins and train compartments. This study proposed a modified tracer-gas-concentration decay method that combined the multi-zone technique and genetic algorithm to determine ventilation rate in...
