artefacts in rbs analysis of laser treated surfaces

laser treatment of deposited films often result in globules on the surface which may influence the solute depth profiles, as measured by rutherford backscattering spectrometry (rbs). the authors show that the globules generally have poor adhesion to the substrate and can be easily removed using techniques commonly employed for testing adh..

methods for internet monitoring

the widespread acceptance of the local area network (lan) coupled with the need to provide network connectivity across several physical locations has led to increased usage of the structure of interconnected packet networks called an 'internet'. unfortunately, there is a scarcity of experimental data on the traffic statistics of such netw..

axial transport of fission gas in lwr fuel rods

with regard to fission gas transportation inside fuel rods, the following three mechanisms are important' (1) a localized and time-dependent fission gas release from uo/sub 2/ fuel to the pellet/clad gap: (2) the consequent gas pressure difference between the gap and the plenum: and (3) the inter-diffusion of initially filled helium and r..

second thoughts on 'look and feel' copyright protection for software

in ibid., vol.3, no.3, p.103, the author commented on the decision in whelan associates inc. v. jaslow dental laboratory inc and broderbund software inc. v. unison world inc., and gave her opinion that these decisions spelled the death of the software cloning industry. two recent decisions from us courts indicate that this obituary may ha..

a data dictionary approach to the software engineering of rule based expert systems

discusses the use of a software engineering tool in the form of an augmented data dictionary in the design and documentation of expert systems and demonstrates the use on the siratac plus cotton management expert system. several future areas of research are mentioned, namely the adoption of active knowledge dictionaries and relational vie..

targetting testing effectively

the author discusses the role of nondestructive testing (ndt) in various industries. he suggests that in some industries, ndt is practised in isolation from other activities. as a consequence the ndt, however painstaking, may make little contribution to the preservation of safety or the achievement of the required design life. in order to..

new control system of sinter plants at chiba works

the control systems of nos. 3 and 4 sinter plants at chiba works have been replaced by a hierarchical system that has three layers: digital control system (dcs), integral process computer (p/c), and the central computer (c/c) at chiba works. dcss for nos 3 and 4 sinter plants are independent systems and are composed mainly of 32-loop dual..

paths of ion transport across canine fetal tracheal epithelium

the transport of na/sup +/ and cl/sup -/ across trachea excised from fetal dogs was evaluated from transepithelial electrical properties and isotope fluxes. under basal conditions the tissues were characterized by a lumen-negative potential difference (pd) of 11 mv and conductance of 5.2 ms/cm/sup 2/. the short-circuit current (i/sub sc/)..

bioelectric properties and ion transport across excised canine fetal and neonatal airways

knowledge of liquid secretion by fetal lung stems from studies of sheep. the authors extended these studies to dogs and examined the persistence of the fetal pattern of airway epithelial permeability and ion transport in the neonatal animal. plasma and lung liquid from fetal dogs were analyzed for na/sup +/, k/sup +/, cl/sup -/ and hco/su..
