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...
امروزه فناوری‌های نانو در علوم مختلف کاربرد پیدا کرده و به‌ویژه برای تصفیه فاضلاب‌های صنعتی به‌کار می‌رود. در این تحقیق نانوذرات آهن به‌روش احیای کلرید فریک توسط بوروهیدرید سدیم سنتز شد و تأثیر تغییرات زمان ماند، غلظت نانوذره، غلظت BOD و pH بر راندمان حذف BOD از فاضلاب ...
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...
AutoBAHN (Automated Bandwidth Allocation across Heterogeneous Networks) has specified and is now prototyping a Bandwidth on Demand (BoD) service intended to operate in a multidomain environment using heterogeneous transmission technologies. The AutoBAHN system aims at providing a guaranteed capacity, connection-oriented service between two end points. This paper highlights the architecture of t...
This paper reports a simulation study of the interaction between the Transmission Control Protocol (TCP) and Bandwidth on Demand (BoD) mechanisms in broadband satellite networks. It forms part of a broader effort aiming at the identification of the proper mechanisms and algorithms to efficiently carry TCP traffic over these networks. We investigate two aspects of this rather complicated interac...
Finding the most probable parse tree in the framework of Data-Oriented Parsing (DOP), a Stochastic Tree Substitution Parsing scheme developed by R. Bod (Bod 92), has proven to be NP-hard in the most general case (Sima’an 96a). However, introducing some a priori restrictions on the choice of the elementary trees (i.e. grammar rules) leads to interesting DOP instances with polynomial time-complex...
