It has been shown that polyammonium cations comprising quaternary ammonium and hydrophilic groups such as amide and hydroxyl groups stabilize a redox enzyme bilirubin oxidase (BOD). The BOD catalyzes the reaction: 4[Fe(CN)6]4- + 4H+ + O2 --> 4[Fe(CN)6]3- + 2H2O, and has been a promising enzyme for use as a cathode catalyst in biofuel cells. In this study, the stabilizing effect of poly[oxyethyl...

Water quality data at 12 sites within an urban, a suburban, and a rural stream were collected contemporaneously during four wet and eight dry periods. The urban stream yielded the highest biochemical oxygen demand (BOD), orthophosphate, total suspended sediment (TSS), and surfactant concentrations, while the most rural stream yielded the highest total organic carbon concentrations. Percent wate...

Synoptic water sampling at a fixed site monitoring station provides only limited ‘snap-shots’ of the complex water quality dynamics within a surface water system. However, water quality often changes rapidly in both spatial and temporal dimensions, especially in highly polluted urban rivers. In this study, we designed and applied a continuous longitudinal sampling technique to monitor the fine-...

Exactly eighty years ago the founder of a struggling manufacturing company approached executives at the prominent mail order specialist Sears, Roebuck to demonstrate an electric washing machine. Despite the number of electrics marketed since the first Thor appeared in 1908, Sears sold primarily hand-powered machines. Now Louis C. "Lou" Upton sought to list his product. Just hirty years of age, ...

introduction the automotive industry is one of the largest industries in the world, which is also very important in our country.according to the world bank, the automotive industry can be classified as the projects that have environmental impacts. therefore, the review and analysis of the environmental impacts is conducted to identify the significant effects of pollution caused by the activitie...

A biosensor was developed for the determination of BOD value of fermentation industry effluent. The developed biosensor was fabricated by immobilizing the microbial consortium on cellulose acetate (CA) membrane in close proximity to a DO probe electrode. The microbial consortium was harvested from the fermentation industry effluent. The BOD biosensor was calibrated by using a solution containin...

This investigation examined the accuracy of the BOD POD on a group of Division I collegiate track and field female athletes (N = 30). Hydrostatic weighing (HW) was used as the gold standard method. Body density (Db) values obtained from the BOD POD (Db BP) were compared with those determined by HW (Db HW). Both Db values were converted to percent body fat (%BF) using the Siri equation for compa...

Textile materials from polyester fibres are sensitive to washing, especially at higher temperatures, due their thermoplastic properties, hydrophobic nature and sensitivity the alkaline medium. The issue of microplastic fibres’ (MFs’) release textiles is a topic that attracts attention researchers different scientific fields, since microplastics now among serious environmental risks. In this stu...

Behavior-Oriented Design (BOD) is a development methodology for creating complex, complete agents such as virtual-reality characters, autonomous robots, intelligent tutors or intelligent environments. BOD agents are modular, but not multi-agent systems. They use hierarchical reactive plans to perform arbitration between their component modules. BOD provides not only architectural specifications...
