The reactivity worth of 22.87 grams of 237Np oxide sample was measured and analyzed in seven uranium cores in the Tank-Type Critical Assembly (TCA) and two uranium cores in the Fast Critical Assembly (FCA) at the Japan Atomic Energy Agency. The TCA cores provided a systematic variation in the neutron spectrum between…
This glossary's objective is to provide clear definitions for those who contribute to studies relevant to ecotoxicology but are not themselves ecotoxicologists.This situation applies especially to chemists who need to understand the ecotoxicological literature without recourse to a multiplicity of dictionaries.The glo…
Alkyl naphthalene sulfonate condensates, lignosulfonates, block copolymers, and alkoxylated polyarylphenol derivatives are used as dispersants in pesticide suspension concentrate (SC) and suspoemulsion formulations. Typically, a pesticide formulation could contain either type of dispersant, with the final selection be…
A novel metal-based thermal barrier coating was tested in a spark-ignition engine. The coating was applied to the surface of aluminum plugs and exposed to in-cylinder conditions through ports in the cylinder wall. Temperatures were measured directly behind the coating and within the plug 3 and 11 mm from the surface.…
One of the important requirements of molecular imaging based on PET and SPECT techniques is the quantitative measurement of regional radiotracer activity in order to assess the local physiological and biochemical function. Some of the basic principles and concepts involved in quantitative methods will be described in…
PM2000 is an Fe –Cr – Al oxide dispersion strengthened (ODS) alloy containing 0.5wt% of fine, uniformly dispersed, yttrium oxide particles in a ferritic matrix. The alloys are attractive candidates for high temperature applications since nano-dispersoids improve the creep resistance of the alloys at high temperatures.…
In experiments and numerical simulations of pulsed photothermal temperature profiling, we compare three signal binning approaches. In uniform binning n subsequent signal data points are averaged, quadratic binning follows from the characteristic of thermal diffusion, and geometrical binning utilizes geometric progress…
This chapter reviews the literature reported in 2008 concerning the chemistry of boron, and focusing on those articles and publications that have appeared in ‘high impact’ journals. The text excludes much material or technological chemistry unless original, fundamental or notable for other reasons. Due to space limita…
The Korea Atomic Energy Research Institute (KAERI) had started the operation of the Advanced Thermal-Hydraulic Test Loop for Accident Simulation (ATLAS), which is a thermal-hydraulic integral effect test facility for evolutionary pressurized water reactors of APR1400 and OPR1000. Recently, integral tests for the reflo…
A dynamic compartmental model based on first principles is developed for a tubular solid oxide fuel cell system. The model accounts for diffusion processes, inherent impedance, transport (heat and mass transfer) processes, electrochemical processes, anode and cathode activation polarizations, and internal reforming/sh…

Chapter 6 originally authored by John Hechmer for the first edition and updated by Greg Hollinger for the second edition has been largely revised by David Jones for the current third edition. Authors cover Subsection NB, Class 1 Components. In presenting the rules and requirements for Section III, Subsection NB, the a…
This Chapter reviews the literature reported during 2008 on gold and silver coordination and organometallic chemistry, focusing on general research trends and on compounds with structures, properties and/or applications of interest. The use of the complexes in catalysis is not discussed here.
The production 0films anodic is presented in a solution of sulfuric acid 15% v/v and to a temperature of 20 oC, with constant agitation (100 rpm), and to three different current densities (10, 15 and 20 mA/cm2), to substitute the chromic acid in the process of anodizing of the aluminum alloy 2024-T3. The electrochemic…
Carbon Nitride (CNx) coating showed superlow friction when it slid against a Si_3N_4 ball in dry N_2, and this phenomena took place nitrogen atoms desorption from topmost layer of CNx and structural change from CNx to graphitic layer. However, it was taken place after several thousand friction cycles, so-called runnin…
Composites of Polypropylene (PP) and High Density Polyethylene (HDPE) with three types of continuous sized waste carbon fibres (CF) were manufactured using twin screw compounding. The carbon fibres used were collected as waste product form the 3D weaving process. Compounds with various percentages, between 4.6 % and 1…
In this paper aluminium-doped zinc oxide(ZnO:Al) conducting layer was deposited on polyethylene terephthalate(PET) substrate by r. f. magnetron sputtering method. The effects of gas pressure and r. f. sputtering power on the structural and electrical properties of ZnO:Al thin film were investigated experimentally. The…
This report covers the laboratory studies that have been performed at Nuclear Chemistry, KTH in the project “Bentonite Erosion”. Many of the experiments in this report were performed to support the work of the modelling group and were often relatively simple. One of the experiment series was performed to see the impac…
Analysis of In-Vessel Coolability and Retention with Control Rod Guide Tube Cooling in Boiling Water Reactors
Bioactive ceramics are used for bone-repairing owing to attractive features such as direct bone-bonding in living body, because they have the ability to bond directly to bone. However, there is limitation on clinical applications due to their inappropriate mechanical properties performances such as higher brittleness…
