Improving anaerobic performance and anaerobic power is the critical aspect on successfully in competitions for many athletes. The purpose of current research was to investigating the effect of various pre-competitions warm-up on anaerobic performance. It has been shown that, differences pre-competitions activity may effect on anaerobic and explosive performance. Effect of general warm-up, witho...

the main theme to conduct present research work was to evaluate the effect of anaerobic granular sludge in degradation of two azo dyes. the study was evaluated in batch experiments where anaerobic and aerobic conditions were integrated by exposing anaerobic granular sludge to oxygen. under these conditions, the azo dyes were reduced, resulting in a temporal accumulation of aromatic amines. subs...

ENGLISHThe tapioca industry is one type of agro-industry that widely developed in Indonesia. The problem often arises due to the presence industries waste pollution, especially liquid waste. Tapioca immediately disposed into river flows without any treatment process. purpose this paper provide an overview impact caused by disposal waste, on aquaculture environment and alternative processing tec...

an air filter is a significant element of any mechanical ventilation system. however, the importance and performance evaluation of air filters have not been well publicized and related scientific reports are scarce. in this study, a transportable, off-line, air filter-testing unit (the unit) was designed and utilized to simulate the filter housing of a mechanical ventilation system. the unit wa...

Per- and polyfluoroalkyl substances (PFAS) have gained increasing attention due to the potential health risks that they present. Secondary sludge biosolids are known as notable PFAS emission routes environment. In this study, partitioning behavior of 14 were investigated across four secondary wastewater treatment types (activated sludge, trickling filter, biological nutrient removal, rotating c...

We design moving horizon state estimators for a general model of bioprocesses. The underlying optimization is nonconvex due to the microbial growth kinetics, which are modeled as nonlinear functions. relax constraints so that becomes second-order cone program, can be solved efficiently at large scales. Unfortunately, solutions relaxation inexact and thus lead inaccurate estimates. To recover fe...
