In order to evaluate the performance of biofilter for H2S removal from contaminated air, a 120×14 cm column biofilter was constructed using clear polyacrylic material in conjunction with H2S production and control systems. The column was divided into four stages using perforated plates. The column was packed with a mixture of mushroom compost and snail shell (4:1). The performance of biofilte...

Minimizing the total amount of physical memory consumption of a set of virtual machines (VM) running on a physical machine is the key to improving a hypervisor’s consolidation ratio, which is defined as the maximum number of VMs that can run on a server without any performance degradation. To give each VM just enough physical memory equal to its true working set (TWS), we propose a TWS-based me...

Two maximization problems of Rényi entropy rate are investigated: the maximization over all stochastic processes whose marginals satisfy a linear constraint, and the Burg-like maximization over all stochastic processes whose autocovariance function begins with some given values. The solutions are related to the solutions to the analogous maximization problems of Shannon entropy rate.

The present paper has examined the degrading ability of phenol-oxidizing bacterium, Ralstonia eutropha, for biological removal of methylene blue (MB) from aqueous solutions under aerobic conditions. Results show that MB has been extensively eliminated as a co-metabolism in the presence of supplementary carbon (glucose) and nitrogen (yeast extract and peptone) sources and the experimental observ...

Grady et al. (Reports, 13 June 2014, p. 1268) studied dinosaur metabolism by comparison of maximum somatic growth rate allometry with groups of known metabolism. They concluded that dinosaurs exhibited mesothermy, a metabolic rate intermediate between endothermy and ectothermy. Multiple statistical and methodological issues call into question the evidence for dinosaur mesothermy.

EMG-Driven models predict individual muscle forces, but it is necessary to obtain muscle electromyography (EMG), which is difficult for deep muscle, as vastus intermedius (VI). The purpose of this study is to determine the relative contribution of each quadriceps (QF) components to the knee extension torque by EMG-Driven model, with a protocol of surface VI EMG acquisition, at submaximal isomet...

Introduction: Vaca Muerta is classified as a mesosiderite, a breccia of approximately equal mixture of silicate and metal [1]. The mesosiderite includes several types of igneous pebbles [2], of which various textures suggest collision event(s) between differentiated asteroidal bodies for its formation. The unique textures have been attracting interests to investigate formation mechanisms and hi...
