    Notes: Summary A large number of experiments have been carried out with the object of determining the nature, properties and source of the condensation nuclei produced by the action of a beam of ultra-violet light within an expansion chamber. This paper is essentially a qualitative summary of the results which have been obtained. It is concluded that these experiments show that it is the rubber component of the chambers that has been responsible for the major part of the effect. It is by no means suggested that this is the only source of the nuclei, but it is implied that only apparatus free from rubber should be used in any study of the properties of the nuclei associated with a given gas or vapour.

    Notes: Summary Although the bubble chamber was only invented byGlaser in 1952, there are today over a hundred chambers in use in physics laboratories throughout the world. In the field of high energy physics they have proved to be an invaluable tool and already much information has been obtained concerning very energetic particle interactions and properties of «strange» particles by the use of both hydrocarbon and liquid hydrogen chambers.

    Description / Table of Contents: Résumé Les anomalies du métabolisme de la graisse dans des expériencesin vitro etin vivo ont été décrites ailleurs à la fois pour le diabète et l'obésité. Dans ces études, la libération de glycérol stimulée par l'adrénaline (100 μM) et la phentolamine (100 μg/ml) a été comparée dans le tissu adipeux provenant de groupes de sujets nondiabétiques, non-obèses, diabétiques et obèses. Le tissu adipeux des diabétiques obèses montrait une diminution très significative (p 〈 0.001) de la stimulation de la lipolyse par comparaison au tissu adipeux des non-diabétiques et des non-obèses. Les conditions de l'obésité et du diabète doivent être présentes simultanément pour maintenir cette différence dans la lipolyse. Le diabète ou l'obésité en eux-mêmes ne sont responsables que de différences à peine significatives dans la stimulation de la libération de glycérol. Nous avons discuté les raisons pouvant expliquer ce défaut de la lipolyse chez les diabétiques obèses et âgés concernant les récepteurs des cellules adipeuses, le système adényle-cyclase et la lipase dépendante de l'hormone.
    Abstract: Zusammenfassung Beiin vitro- undin vivo-Studien sind anderweitig sowohl für den Diabetes als auch für die Fettsucht Anomalien des Fettmetabolismus beschrieben worden. In dieser Arbeit wurde die durch Adrenalin (100 μM@#@) und Phentolamin (100 μg/ml) stimulierte Glycerinfreisetzung im Fettgewebe von Patienten ohne Diabetes, von Patienten ohne Übergewichtigkeit und bei Diabetikern mit Übergewicht miteinander verglichen. Das Fettgewebe von übergewichtigen Diabetikern zeigte eine hochsignifikante (p〈0,001) Verminderung der stimulierten Lipolyse im Vergleich zum Fettgewebe von Nicht-Diabetikern und Nicht-Übergewichtigen. Übergewichtigkeit und Diabetes müssen gleichzeitig vorhanden sein, um diesen Unterschied in der Lipolyse aufrecht zu erhalten. Diabetes und Übergewicht allein sind nur für gering signifikante Unterschiede bei der stimulierten Glycerinfreisetzung verantwortlich. Die möglichen Ursachen für diesen Mangel in der Lipolyse bei übergewichtigen älteren Diabetikern, die die Fettzellrezeptoren, das Adenyl-Cyclase-System und die hormonempfindliche Lipase betreffen, wurden diskutiert.
    Notes: Summary Abnormalities of fat metabolism fromin vitro andin vivo experiments have elsewhere been described in both diabetes and obesity. In these studies adrenaline (100 μM) and phentolamine (100 μg/ml) stimulated glycerol release has been compared in adipose tissue from groups of non-diabetic, non-obese, diabetic and obese subjects. Adipose tissue from obese diabetics showed a highly significant (p〈0.001) diminution in stimulated lipolysis when compared with non-diabetic, non-obese adipose tissue. The conditions of obesity and diabetes are required to be present simultaneously to maintain this difference in lipolysis. Diabetes or obesity per se are responsible for only marginally significant differences in stimulated glycerol release. The possible reasons for this defect in lipolysis in obese elderly diabetics, pertaining to fat cell receptors, the adenyl cyclase system and the hormone sensitive lipase have been discussed.

    Notes: As an extension of the previous paper, we derive a similar theory for the plane Poiseuille flow of a dilute polymer solution. The strict enforcement of reflective boundary conditions allows an approximate solution to the Fokker–Planck–Kolmogorov equation to be obtained which is found to be consistent with solutions obtained by Galerkin methods and Monte Carlo simulation. The approximate theory also allows us to derive analytical expressions for the slip velocity and the effective viscosity which are again consistent with the plane Couette flow results derived in the previous paper. The theory is also extended to the nonlinear Warner spring model via Monte Carlo simulation.

    Notes: Existing experimental data have suggested that the flow of a dilute polymer solution near a wall exhibits a slip effect. In the case of a plane shear flow, the suspension of macromolecules contributes a nonuniform stress field profile across the channel which causes the velocity field to deviate from its otherwise linear profile. The apparent slip velocity can be calculated from such deviation. In this paper, we consider the flow problem of a suspension of bead-spring molecules in the presence of solid reflective boundary. Analytical and simulation solutions to the problem are obtained which do not require any small shear rate assumption. The added stresses contributed by the molecules are used to derive the slip velocity and the effective viscosity. Extension to nonlinear Warner spring model is also attempted by the simulation and the results give rise to some qualitative features which cannot be accounted for by the linear model.

    Notes: Background:  There is growing literature suggesting that some children diagnosed with attention deficit hyperactivity disorder (ADHD) can show a significant bias in attention away from left space. Here we examine mechanisms that may underpin these effects in both clinical and non-clinical child populations. Unilateral spatial inattention (unilateral neglect) is a commonly reported consequence of stroke in adults. Although for most patients the problem is relatively transient, persistent forms of neglect are almost exclusively associated with right hemisphere lesions. It has been suggested that this chronicity may result from co-existing disruption to right hemisphere dominant systems that mediate alertness. Here we present two studies examining the relationship between sustained attention and left spatial awareness in childhood.Method:  In the first, normal children without the ADHD diagnosis were administered a non-spatial test of sustained attention/alertness. Children who performed poorly at this task, relative to their more attentive peers, showed a modest but reliable delay in awareness of left-sided visual information. Furthermore, attention towards the left declined for both groups as a function of time-on-task, suggesting a significant within-subject modulatory effect of alertness on spatial awareness. The second study examines this relationship in children referred to clinical services for attention problems. Irrespective of their final diagnosis, children were divided into two groups according to their performance in sustained attention/alertness tasks.Results:  The results suggest that, regardless of the children's clinical diagnosis, diminished sustained attention/alertness levels formed the strongest predictor of relatively delayed awareness of information presented within left visual space. Two children within this group exhibited signs of hitherto undetected spatial neglect as severe as that observed in some brain-injured adults.Conclusions:  Clinical and theoretical implications are discussed. Keywords: Sustained attention, visuo-spatial attention, normal 6–7-year-old children.

    Notes: A robotic system for testing fabrics under low-stress conditions has been developed at UMIST. This system is capable of conducting all the mechanical tests on a single piece of fabric, without operator intervention, thus eliminating human-related errors. Looks at test control strategy and acquisition of force and deformation data, from the viewpoint of process control in garment assembly.
