The 5-day biochemical oxygen demand (BOD5) test has been used for over a century to evaluate the concentration of biodegradable organic matter in wastewater effluents. The BOD test is a simple batch test, but it is also time consuming, labor intensive, imprecise, and, due to the dilution of the wastewater, takes a relatively long time to complete. Advances in laboratory instruments and lab ware...
I examine the relationship between board of director’s (BoD) education and firm performance on a European dataset over the period from 1999 to 2013, employing a well-developed dynamic panel generalized method of moments (GMM) estimator to alleviate endogeneity issue in corporate governance study. I find no correlation between BoD education and firm’s return on asset, after accounting for endoge...
This paper focuses on the Call Control for the establishment and release of isochronous calls within the DAMS network (ESPRIT project #2146), a distributed ISDN PBX over an FDDI-II backbone optical ring that supports both isochronous and asynchronous traffic generated by ISDN terminals, LAN terminals, and Bandwidth On Demand (BOD) terminals. After a general overview of the DAMS network architec...
The discoloration of a biologically pretreated waste water stream from a molasses processing by ozonation and two advanced oxidation processes (O3/H2O2 and 03/7-irradiation, respectively) was studied. Colour removal occurred with all three processes with almost the same efficiency. The main difference of the methods applied was reflected by the BOD increase during the discoloration period. By o...
The redox potentials of the multicopper redox enzyme bilirubin oxidase (BOD) from two organisms were determined by mediated and direct spectroelectrochemistry. The potential of the T1 site of BOD from the fungus Myrothecium verrucaria was close to 670 mV, whereas that from Trachyderma tsunodae was >650 mV vs. NHE. For the first time, direct electron transfer was observed between gold electrodes...
In this paper we examine the implications of ideal and anti-ideal decision-making units on Benefit-of-the-Doubt (BoD) model. particular, verify that, in presence an (anti-ideal) unit, efficiency scores BoD (inverted BoD) model can be obtained without solving relevant linear programming problems. case, it suffices to choose largest (smallest) element-wise divided component indicators evaluated u...
