Authors: Mungioli Maria Cristina Palma , Lemos Ligia Maria Prezia , Karhawi Issaaf 
Published: November 2015

<p>Este artigo analisa elementos da minissérie A cura (Globo, 2010) inserindo-os no quadro das narrativas fantásticas produzidas pela televisão brasileira na primeira década do século XXI. Presente na ficção televisiva brasileira, sobretudo a partir de meados da década de 1970, a narrativa fantástica (TODOROV, 2008) teve papel preponderante na constituição de um estilo de narrar e de um acabamento estético genuinamente brasileiros na televisão (BORELLI, 2001).</p>
O discurso jornalístico sobre a instalação da Comissão Nacional da Verdade
Authors: Abreu Carmen 
Published: November 2015

<p>A proposta é analisar os sentidos produzidos pelo discurso jornalístico a partir de um corpus de textos publicados nos jornais Folha de S. Paulo, O Estado de S. Paulo e O Globo sobre a instalação da Comissão Nacional da Verdade. A partir de pressupostos da análise de discurso (AD), com base no conceito de silenciamento (ORLANDI, 2007), observa-se que as manchetes destes jornais reforçam a dificuldade que a imprensa brasileira, em geral, ainda tem em enfrentar o tema da ditadura, pois não é capaz de situar seu leitor acerca da importância do resgate histórico deste período para a consolidação da democracia brasileira. Considera-se a cerimônia de instalação da referida Comissão como um acontecimento histórico e jornalístico atual que ao mesmo tempo está impregnado de passado e carrega uma expectativa de futuro.</p>

Myeloid-Derived Vascular Endothelial Growth Factor and Hypoxia-Inducible Factor Are Dispensable for Ocular Neovascularization—Brief Report
Authors: Liyanage Sidath E. , Fantin Alessandro , Villacampa Pilar , Lange Clemens A. , Denti Laura , Cristante Enrico , Smith Alexander J. , Ali Robin R. , Luhmann Ulrich F. , Bainbridge James W. , Ruhrberg Christiana 
Published: November 2015

Objective—
Ocular neovascularization (ONV) is a pathological feature of sight-threatening human diseases, such as diabetic retinopathy and age-related macular degeneration. Macrophage depletion in mouse models of ONV reduces the formation of pathological blood vessels, and myeloid cells are widely considered an important source of the vascular endothelial growth factor A (VEGF). However, the importance of VEGF or its upstream regulators hypoxia-inducible factor-1α (HIF1α) and hypoxia-inducible factor-2α (HIF2α) as myeloid-derived regulators of ONV remains to be determined.

Approach and Results—

We used 2 mouse models of ONV, choroidal neovascularization and oxygen-induced retinopathy, to show that
Vegfa
is highly expressed by several cell types, but not myeloid cells during ONV. Moreover, myeloid-specific VEGF ablation did not reduce total ocular VEGF during choroidal neovascularization or oxygen-induced retinopathy. In agreement, the conditional inactivation of
Vegfa
,
Hif1a
, or
Epas1
in recruited and resident myeloid cells that accumulated at sites of neovascularization did not significantly reduce choroidal neovascularization or oxygen-induced retinopathy.

Conclusions—
The finding that myeloid cells are not a significant local source of VEGF in these rodent models of ONV suggests that myeloid function in neovascular eye disease differs from skin wound healing and other neovascular pathologies.
D-4F Decreases White Matter Damage After Stroke in Mice
Authors: Cui Xu , Chopp Michael , Zacharek Alex , Cui Chengcheng , Yan Tao , Ning Ruizhuo , Chen Jieli 
Published: November 2015

Background and Purpose—
Stroke-induced neuroinflammation and white matter damage are associated with neurological deficits. Whether D-4F, an apolipoprotein A-I mimetic peptide, treatment of stroke decreases neuroinflammation and white matter damage and improves functional outcome has not been investigated.

Methods—
Adult male C57BL/6 mice were subjected to permanent middle cerebral artery occlusion (MCAo) and were orally administered saline as a vehicle control and different doses of D-4F (2, 4, 8, 16, or 32 mg/kg) starting at 2 h after MCAo and daily until euthanized at 7 days after MCAo. D-4F treatment did not alter the blood levels of high-density lipoprotein, total cholesterol, triglyceride, blood–brain barrier leakage, and infarction volume compared with control group.

Results—

D-4F (16 mg/kg) treatment of stroke significantly improved functional outcome, increased the white matter density and the number of oligodendrocyte progenitor cells in the ischemic boundary zone of the ipsilateral striatum, and increased myelin basic protein, insulin-like growth factor-1 (IGF1), but decreased inflammatory factor Toll-like receptor-4 and tumor necrosis factor-α expression in the ischemic brain 7 days after MCAo (
P
<0.05, n=11/group). The neurite/axonal outgrowth in primary cultured neurons was significantly increased when treated with D-4F (100 ng/mL) and IGF1 (100 ng/mL) compared with the nontreatment control. Inhibition of IGF1 significantly attenuated D-4F or IGF1 treatment–induced axonal outgrowth. D-4F-treatment did not increase oligodendrocyte–progenitor cell proliferation but decreased oligodendrocyte–progenitor cell death.

Conclusions—
D-4F treatment initiated 2 h after MCAo decreases neuroinflammation and white matter damage and improves functional outcome after stroke. D-4F-induced increase in IGF1 may contribute to D-4F–induced neurite/axonal outgrowth after stroke.
Morphological and molecular characterisation of one new and several known species of the reniform nematode, Rotylenchulus Linford & Oliveira, 1940 (Hoplolaimidae: Rotylenchulinae), and a phylogeny of the genus

Published: November 2015

The reniform nematodes of the genusRotylenchulusare semi-endoparasites of numerous herbaceous and woody plant roots and are mainly distributed in tropical and subtropical regions. In this study, we provide morphological and molecular characterisation of six out of ten presently known valid species ofRotylenchulus:R. clavicaudatus,R. leptus,R. macrodoratus,R. macrosoma,R. reniformisandR. saccharifrom South Africa, USA, Italy and Spain.Rotylenchulus parvuswas only studied morphologically. A new species,R. macrosomoidessp. n., isolated from soil and roots of sugarcane in South Africa, is described. The phylogeny ofRotylenchulus, as inferred from the analyses of D2-D3 of 28S rRNA, ITS rRNA,coxImtDNA andhsp90gene sequences, is presented. The study revealed thatR. reniformisandR. macrosomahave a sister relationship, but that relationships between otherRotylenchulusspecies remain unresolved. The phylogenetic analysis also confirmed the hypothesis that this genus originated from the Afrotropical zoogeographical region. Our study revealed thatR. reniformisandR. macrosomoidessp. n. have two distinct rRNA gene types andR. macrosomahave three rRNA gene types in their genomes. PCR with species-specific primers was developed for rapid diagnostics ofR. reniformis.
Note sur l’adverbe temporel już et ses correspondants français
Authors: Nowakowska Małgorzata , Apothéloz Denis 
Published: November 2015

A remark concerning the temporal adverb już and its French equivalentsGenerally speaking, this contrastive study of the Polish temporal adverb już and the French déjà is based around the idea that już and déjà have an invariant meaning but it is also true that they follow different idiosyncratic usages. This article has two parts. First, the authors show the usages of już which are equivalent to those of déjà. These usages appear when już and déjà are put in a specific verbal context. The authors describe the four cases in which już and déjà are equivalent: “precocity of event”, existential usage, iterative-continuative usage, experiential perfect usage. Secondly, the authors analyze four cases in which the Polish adverb już can’t be translated by the French déjà. These incompatibilities can be explained by either morphological idiosyncrasy or the conventionalization of deictic meaning of już, which is absent of déjà.
Human, Machine, and Environment Aspects of Snowmobile Design and Utilization
Authors: Rabideau Gerald F. 
Published: November 2015

Central to the many problems inherent in the design and use of snowmobiles is their rapid increase in popularity as sporting and recreational vehicles during the past decade. The major problems-damage and injury-producing accidents, noise pollution, damage to private property, and detrimental effects on natural ecology—are described and analyzed. Examples are given that typify the current state-of-the-art investigations of the problem areas. It is noted that such studies, both scientific and engineering, have dealt only in piecemeal fashion with some of the most widely acknowledged problems. The paper examines the existing need for a system-oriented program of research designed to provide data for a wide range of system design standards capable of assuring the survival of this form of recreation.
Sources and Uses of Energy
Authors: Jones Henry 
Published: November 2015

It is a privilege and an honour for me to have been invited to give a lecture associated with Sir George Thomson, a man whom I had the experience of working with when he was Chairman of the Ministry of Power's Scientific Advisory Council and I was one of the Council members. I will not attempt an appreciation of his scientific work, particularly distinguished in nuclear physics, but I can say that his qualities of intellect and personality made a most impressive impact on his colleagues on the Council. My choice of subject is very wide, but so is the effect of energy on our daily lives. After a brief discussion of the way in which we need and use energy I will describe the major sources available to the world, with a more detailed examination focused on North Sea gas. Moving on to a brief review of the uses of energy in Great Britain, the lecture will close with an outline of the Gas Council's plans.
Temperature Control in Extrusion the Requirements for Temperature Control
Authors: Grant D. , Wilkinson P. 
Published: November 2015

The object of this paper is to try to analyse, and also to some extent to justify, the temperature control requirements of the screw extrusion process. This paper and the following paper on ‘Design Strategies for the Control of Temperature’ will, we hope, be of interest both to the section of the Plastics Industry that uses extruders, and also to that part of the Instrumentation Industry which is concerned with the control of temperature. We believe that, in sectors of both industries, there are still many misconceptions as to the nature of the extrusion process and about the equipment used. To start with, we do not believe that the Plastics Industry knows the standard terms used by the Instrumentation Industry to describe the different types of instrument they employ. We hope Table I will help to clarify this situation. We also believe that the Instrumentation Industry has a limited understanding of the extrusion process, and so before describing what we believe to be the requirements for temperature control in extrusion, we will survey briefly the materials, products, properties, tolerances and also the equipment associated with this process.
A Rapid Synthesis Technique for the Duplicator Class of Feedback Control Systems
Authors: Towill D. R. 
Published: November 2015

A technique suitable for the rapid synthesis of the duplicator class of feedback control systems is developed. Simultaneous requirements of maximum percentage overshoot, bandwidth and velocity constant, such as commonly specified in instrument servomechanisms, are satisfied by the technique, which uniquely defines the compensation terms required to satisfy the specification. The techniques make use of the fact that many feedback control systems, irrespective of order, are dominated by a few system poles and zeros, and therefore places either one system zero, and two system poles, or an integrating dipole and two system poles in the dominant part of the s plane. Straight-line approximations to the Bode plot of amplitude ratio only are used in conjunction with a dummy transfer function, the coefficients of which are obtained directly from the performance specification by means of a universal chart. Digital computer results are given in verification of the accuracy of the technique. The approach is sufficient for the design of feedback control systems for which a linear or small perturbation model is adequate, provided the open loop dynamics can be approximated by the straight-line Bode plot. If the small perturbation model is inadequate, but a linear design approach is still chosen, the technique may be used to define trial systems for subsequent detailed nonlinear studies on the analogue computer.
An Automatic Moisture Meter Using Radio Frequency Heating
Authors: Scott J. A. 
Published: November 2015

In one manufacturing process ICI, Nobel Division it became necessary to measure the moisture content, around 60 per cent, of a hot, sticky solid. The normal laboratory method involved drying in an oven at 100°C for 16 hours, the lengthy time required being due to the fact that on drying the material forms a hard external skin which greatly reduces the rate of loss of water. Such a delay meant that the results were of little value in the day to day running of the plant, and a rapid method was sought. Among numerous methods which were considered, in some cases tested, and rejected were measurement of conductivity, dielectric constant, density and microwave attenuation. The principal difficulty was the intractable condition of the sample and the fact that it contained much occluded air. Finally the effect of radio frequency heating was tried, and it was found that a 5 gm sample could be dried completely in 10 min. This was used as the basis for a successful laboratory method for determining moisture and subsequently a request was received for an automatic instrument operating on this principle and capable of being used by unskilled labour.
The Equivalent Gain Matrix of a Multivariable Non-Linearity
Authors: West John C. 
Published: November 2015

The equivalent gain concept of a mono-variable non-linear stochastic process is used to evaluate the linear matrix equivalent of a multi-variable non-linearity having n independent inputs and m outputs. It is shown that if the n inputs are restricted to separable class of processes (which includes Gaussian random signals and also sinusoidal wave forms but is much wider), then the distortion terms produced by the non-linearity and by cross modulation have zero cross-correlation with any of the input signals.

Published: November 2015

The main concern is with the applications of a radar dopplermeter which has recently become available. Laboratory trials have been carried out to investigate its use in the process industries especially as a potential interrogating unit in a control system. Useful features, and some of the disadvantages are exposed and comparisons are made between dapplermeters using radar and laser sources. These and other techniques are under patent application.
Hydraulic Gap Control on Strip Rolling Mills
Authors: Collinson C. D. 
Published: November 2015

Early applications of hydraulic loading were confined to foil rolling mills but recent developments have been rapid. Prestressed mills were adopted to obtain high stiffness and stability. The addition of modern quickly-responding electro-hydraulic equipment and accurate transducers has given these mills even higher effective stiffness and resulted in very good gauge control. The proving of hydraulic load and position controls in service on these mills has enabled them to be applied with confidence to ‘pure’ (screwless) hydraulic mills which are less costly than conventional mills and give improved performance. They are being widely adopted. Control methods, the requirements for transducers, hydraulic systems, etc., and the essential functions of a hydraulic gauge control are described herein.
A Drag Plate Flowmeter for Pulsating Flow
Authors: Hunter J. J. , Green W. L. 
Published: November 2015

A survey of recent articles shows that drag plate flowmeters, in one form or another, have been about the most popular devices for indicating transient flows. Design principles are given and features discussed, which affect performance in transient or pulsating flow. Where a transient flowmeter has an electrical output it is quîte easy to process the output signal so as to obtain the average flow under pulsating conditions of flow. Thus the drag plate flowmeter is of interest for this important application. Up to the present the transient performance of these flowmeters has been inferred from the examination of the output waveform and from the comparison of the indicated flow with true average flow under pulsating conditions. Details of frequency analysis tests of a drag flowmeter are given.
Applying the Concepts of Control
Authors: Bishop David M. 
Published: November 2015

Introducing his Address, Mr Bishop said that since it had been decided that the President should not necessarily give his address in London, he had no hesitation in selecting Teesside, where he lives and works, and where his own Local Section resides. Moreover, Teesside won the David Nutting Award for its contributions last year to the affairs of the Institute. Mr Bishop also spoke of the recently announced granting by Her Majesty The Queen of a Royal Charter, which he saw as recognising the standing of the Institute. He said: It might be thought by some that the standing of this Institute has been enhanced by the granting of a Royal Charter. In the formal sense this is no doubt true, but as I see it what has happened is that our standing has been recognised and that we are now in a position which we have earned by our achievements. But with this recognition we are also given increased responsibility, and we must see to it that we respond, and that we justify the trust placed upon us. If we wish to further enhance our standing we shall not do so by resting on our laurels, or by mere talk. If we are to become well-regarded, not just by our fellow scientists and engineers, but by the world at large, then we will have to do things which beneficially affect the world at large to the point that people notice and wish to applaud. The President also paid tribute to the work of a Past-President, Mr David Nutting, and the Secretary, Mr Edgar Eden, for their efforts in preparing and presenting the petition.
Thermocouples above 600°C: Infra-Red Thermometers and Optical Pyrometers
Authors: Barber R. , Brown M. E. 
Published: November 2015

This paper outlines the important features in the calibration of all types of thermocouples and infra-red thermometers using the established methods of calibration. The International Practical Temperature Scale of 1968 is described with reference to the fixed points and methods of interpolation between them. The principle of traceability is described and also the various traceability routes via Absolute, Secondary and Transfer Standards which can be employed. Importance is placed on the provision of written procedures, schedules for routine checking and maintenance of full and accurate records. This work should be the responsibility of a co-ordinating expert. Descriptions are given of temperature sources and ancilliary equipment necessary for establishing a works laboratory which requires traceability to National Standards. The normally attainable levels of uncertainty are given for a number of examples.
Improvements in the Design and Operation of a Suction Pyrometer
Authors: Wojtan M. S. , Jones K. A. G. 
Published: November 2015

There is a need to make reliable gas temperature measurements in combustion research. Conventional suction pyrometers and the associated methods of estimating their error do not always give satisfactory results. A new suction pyrometer has been developed to meet the requirements of a specific project at the Coal Research Establishment of the NCB. The unit incorporates a means of estimating directly the error in the pyrometer reading at the time the gas temperature is measured. The pyrometer has been used to measure gas temperatures in a wide range of environments. The results demonstrate the advantages of using the new pyrometer.
