Effect of cellulase/glucanase/xylanase (Roxazyme G2) enzymes combination on nutrients utilisation of vegetable meal (Amaranthus cruentus) fed as sole dietary protein source in rat assay

Amaranthus cruentus vegetable meal (ACVM) had 23% crude protein. Ca, Na, K, Mg and Fe were abundant at 2.0 g kg^?1, 7.1 g kg^?1, 4.8 g kg^?1, 2.5 g kg^?1, 1109 mg kg^?1, respectively. P‐phosporous, oxalates and tannins were noticeable. Lysine, methionine and cystine were limiting. Weight gain for rats on the reference (casein) diet 2 at 6.30 g ±2.87 was highest (P < 0.05) followed by diet 6 (12% ACVM with enzyme supplementation) at 5.01 g ±2.42. Feed intakes were similar (P > 0.05) for rats on the reference diet and for rats on 10% and 12% with/without enzyme supplementation ranging from 42.90 g ± 4.52 in reference diet to 45.12 g ± 3.64. Nitrogen retention was highest for rats on reference diet but similar (P > 0.05) to rats on 12% enzyme supplemented diet at 0.53 ± 1.12 and 0.53 ± 2.10, respectively. Other investigated protein evaluation parameters revealed similar results among rats kept on reference diet and the rats on ACVM based diets with enzyme supplementations. Enzyme supplementation had a complimentary role in ACVM nutrition in rat trial.     

“Used fuel” vectors and waste minimization strategies for VHTRS operating without refueling

Generation IV Very High Temperature Reactors (VHTRs) are well-known for their flexibility with respect to feasible fuel cycle options. In this paper, the LEU- and TRU-fueled VHTR configurations are analyzed accounting for their capabilities to attain an extended single-batch OTTO (Once-Through-Then-Out) mode of operation without intermediate refueling. The requirement of waste minimization is imposed as one of the design constraints defining possible system configurations and deployment strategies. The resulting “used fuel” vectors are examined considering anticipated disposal options as well as viability of fuel reprocessing. A Monte Carlo-deterministic analysis methodology has been implemented for coupled design studies of VHTRs with TRUs using the ORNL SCALE 5.1 code system. The developed modeling approach provides an exact-geometry 3D representation of the VHTR core details properly capturing VHTR physics. The presented analysis is focused on prismatic block core concepts for VHTRs. It is being performed within the scope of the U.S. DOE NERI project on utilization of higher actinides (TRUs and partitioned MAs) as a fuel component for extended-life VHTR configurations.     

Legal Framework for Alternative Dispute Resolution: Examination of the Singapore National Legal System for Arbitration

Effectiveness of any alternative dispute resolution (ADR) method depends on the national legal system to which it is subjected. In Singapore, the increasing growth in the use of ADR methods may be adduced to developments in the Singapore legal environment. This paper reviews the characteristics of the Singapore national legal system for arbitration. It examines how the legal system facilitates effective use of ADR. By its features, the Singapore national legal system ensures parties’ autonomy but deters parties from taking opportunistic advantage of the voluntary nature of ADR. It enables procedural flexibility, and confidentiality of arbitration proceedings. It insulates the arbitration process from intervention from the Singapore courts and from corruption; and it provides maximum judicial support in the arbitral process. Hence, it ensures that disputes can be brought to a conclusion within a reasonable amount of time, at a reasonable cost, as well as preserving business relationships. The Singapore legal system insures the integrity of arbitration and the independence of arbitrators and arbitral institutions by immunity provisions. In addition, the legal system enhances the use of mediation and conciliation in a sequential tier with arbitration by providing a time limit for mediation or conciliation to terminate should they fail to produce a mutually acceptable settlement. In Singapore, the court system is generally known to be efficient; hence, ADR faces the practical challenge of becoming lengthier than court proceedings. The continuing search for and use of expedited arbitration procedures by arbitral institutions such as the Singapore International Arbitration Centre should reduce this challenge. This paper provides useful information on how a national legal system may be designed to support the use of ADR methods and facilitate their effectiveness.
