    Notes: The response characteristics of palladium-gate metal-insulator-silicon field-effect transistor (MISFET) structures to hydrogen are shown to be logarithmically related to the partial pressure of the gas. It is proposed that these palladium-gate MIS structures should be considered as electrochemical devices where the metal/insulator structure behaves as a gas electrode. The results presented were obtained for hydrogen in air and therefore relate directly to the use of these devices as sensors for use in the ambient environment.

    Notes: The NOVA laser has completed its first year of operation. During this period, emphasis has been placed on activation of the facility and of the numerous target and beam diagnostics. Two separate target chambers are in use. NOVA operation is separated into two broad functions: laser operations and experiments. The operations group provides the laser system control, operation, and data acquisition and the experiments group provides experiment definition, diagnostic instrumentation, and overall data processing. On the operations side, VAX 11/780 computers are used to set up diagnostic operating parameters and collect data recorded by the CAMAC and CCD modules. These data are delivered in files by electronic link to the Laser Experiments and Analysis Facility (LEAF) VAX 11/785 of the experiments group for processing. Film data are digitized at LEAF and the film data files are also processed on the LEAF VAX. The LEAF provides collection, processing, analysis, and archiving of the experimental data. The many applications software packages written for LEAF provide the experimental physicists and NOVA operations staff with programs and data bases for interpretation of experimental results. This software makes fundamental use of the ORACLE relational data base management system to both access the required data and archive the obtained results. Post-shot data processing produces sets of scalar values, x, y profiles and x, y, z contour data. The scalar data are stored in the ORACLE DB; the more extensive results are stored in binary files on disk. All data forms are accessed by a comprehensive software system, the electronic SHOTBOOK, developed around the ORACLE DBMS. This software also provides the means to archive relevant data about each experimental activity and allows the physicists to annotate displayed experimental results with technical comment.

    Notes: Summary A survey of remedial teaching based on a particular method and carried out in an NHS clinic over 2 years has been presented. The findings suggest a differential pattern of improvement both for reading and spelling as well as for type of learning difficulty, whether ‘backward’ or ‘specifically retarded’. A plea for early recognition of specific learning difficulties and the provision of appropriate remedial teaching is made as the present findings suggest that a structured method of teaching can lead to improvement in both reading and spelling.

    Notes: [Auszug] Figure 1 outlines the geology of the Falkland Islands, and the inset shows the position they occupied before the opening of the South Atlantic in the Lower Cretaceous. This position is obtained by closing the South Atlantic by an anticlockwise rotation of the South American plate through 56.40 ...

    Notes: Abstract A 5-year-old white boy presented with life-threatening haematemesis from spontaneous rupture of an aneurysm of the high cervical internal carotid artery (ICA). The haemorrhage was controlled by emergency trap ligation of the distal ICA in the neck. The child made an excellent recovery and 7 years later has no neurologic deficit other than an Horner's syndrome. The diagnosis of an extracranial carotid artery aneurysm without a pulsatile lump may be very deceptive.

    Notes: Abstract Two systems for measuring embryo development in vitro were evaluated. One was a 1–4 scale based on a subjective evaluation of embryo quality (EQ) from microscopic appearance. In addition, a formula for scoring embryo growth rate in vitro was developed. The embryo development rating (EDR) was based on the ratio between the time at which embryos were observed at a particular stage after insemination and the time at which they would be expected to reach that stage in a hypothetical “ideal” growth rate with a cell cycle length of 11.9 hr. Using this scoring system, “normally” growing embryos scored 100. This approach was aimed at partially normalizing the data and allowed all embryos to be analyzed similarly regardless of the time of observation. Analysis of 1539 embryo replacements resulting in 232 clinical pregnancies showed that both EDR and embryo-quality scores were of value in predicting success, with clinical pregnancy most likely to eventuate from a combination of moderate to good EQ scores (2–4) coupled with average or above-average growth rates (EDR scores from 90 to 129). Poor-quality and very slowly or very rapidly growing embryos were underrepresented in cycles that proceeded to pregnancy. These inferences were based on all embryos transferred (mean, 2.73 per transfer cycle), and they were substantiated by an analysis of 33 pregnancies resulting from replacement of a single embryo and from 18 pregnancies in which all embryos scored the same with both systems. EQ and EDR were significantly associated with each other and together provide a valuable guide in predicting pregnancy, in selecting embryos for freezing, and in monitoring day-to-day performance in the in vitro fertilization (IVF) program.
