O método Análise de Cobertura Jornalística e o acontecimento noticioso da doença do ex-presidente Lula
Authors: Silva Gislene , Soares Rosana De Lima 
Published: November 2015

<p>Nesta reflexão sobre o jornalismo defendemos uma perspectiva teórico-epistemológica, pela qual entendemos ser metodologicamente viável pesquisar em uma das três instâncias do circuito comunicativo (produção, produto e recepção) dinâmicas que informem sobre as demais. Tomamos o pressuposto de que o acontecimento jornalístico pode ser observado e analisado por meio das marcas que o processo de produção da notícia deixa visíveis no próprio produto acabado. Assim, a nossa hipótese sugere que as coberturas jornalísticas, entendidas como estratégias de apuração e angulação, configuram um mesmo acontecimento social em diferentes acontecimentos jornalísticos. Como objetivo último, a reflexão trazida aqui quer investir na notícia como tradução do fato, mais conceitualmente como tradução cultural.</p>
Entre o céu e a terra: a cobertura das catástrofes e o discurso das autoridades
Authors: Amaral Márcia Franz , Pozobon Rejane De Oliveira 
Published: November 2015

<p>O trabalho se propõe a confrontar o discurso das fontes autorizadas com o das fontes experts em catástrofes climáticas, a partir da cobertura jornalística das revistas semanais sobre os deslizamentos ocorridos no Rio de Janeiro, no início de 2011. Ancorado em aportes da Análise do Discurso, buscamos as famílias parafrásticas mais recorrentes nas declarações dessas fontes no que tange às responsabilidades pela catástrofe. Na análise de sete revistas, concluímos que as fontes experts dedicam-se a tentar explicar cientificamente os fatos, a partir de uma atitude avaliativa e propositiva. Já as fontes autorizadas trazem um discurso totalmente despolitizado, não tomando para si as responsabilidades que lhe cabem no momento.</p>
Os ritornelos da canção cinematográfica: escuta, imaginário e imaginação
Authors: Rodrigues Rodrigo Fonseca 
Published: November 2015

<p>A empática ressonância entre a canção e o cinema fornece um manancial expressivo para a exploração de diferentes imbricações entre a dramaturgia, os ritmos pictóricos e o universo da palavra cantada nos filmes. Este artigo examina a singularidade formal da canção e sua consubstanciação criativa entre as sonoridades, a visualidade e a narrativa cinematográficas. O debate teórico é apoiado pelas ideias de Michel Chion acerca de como a canção diversifica o prisma expressivo do cinema e o conceito de ritornelo desenvolvido por Gilles Deleuze e Félix Guattari (1997) para se conceber a escuta cinematográfica da canção como uma implicação de ritmos do tempo – memórias e devires – materializados como ritmos da imagem, das sonoridades, da ficção e da palavra cantada.</p>
Imersão em jogos pervasivos
Authors: Oliveira Thaiane Moreira de 
Published: November 2015

<p>O objetivo deste trabalho é refletir acerca dos processos imersivos em jogos pervasivos, sobretudo, os jogos de realidade alternada, nos quais o transbordamento entre realidades e ficcionalidade permite uma experiência coletiva calcada pelo fingimento partilhado. Desta forma, busca-se compreender quais são as subjetividades implicadas nas interações em jogos pervasivos, tendo em vista que tais gêneros de jogos não estão restritos à utilização de apenas um único suporte midiático. Eles possuem uma temporalidade própria, para além da temporalidade comum dos sujeitos interatores e os jogadores, enquanto indivíduos, são interdependentes da coletividade para a vivência da experiência imersiva.</p>
Fábulas da vida obscura: imagens técnicas e anonimato
Authors: Figueiredo Vera Lúcia Follain de 
Published: November 2015

<p>A partir do final do século XVIII, o homem comum é cada vez mais objeto do olhar não só das instituições de controle da ordem social, mas também da técnica, da ciência e da arte. O esforço de desvelamento visando neutralizar a força ameaçadora das massas urbanas, no entanto, conviveu sempre com a contrapartida das estratégias de ocultamento, como as conspirações, os complôs. Considerando que, com o avanço das tecnologias da comunicação, a oposição entre exibir e ocultar tornou-se cada vez mais tênue, o artigo discute o alcance da dicotomia visibilidade/invisibilidade quando se trata de estabelecer relações entre as práticas culturais e a política.</p>
A visibilidade dos anônimos
Authors: Serelle Marcio 
Published: November 2015

O seminário A visibilidade dos anônimos, realizado pelo grupo de pesquisa Mídia e Narrativa, na Pontifícia Universidade Católica de Minas Gerais (PUC-MG), em novembro de 2013, reuniu pesquisadores do país para debater, entre outros temas, as inscrições das multidões, os contrapontos e passagens entre o anonimato e a vida célebre, a redistribuição de lugares midiáticos na contemporaneidade. Dividimos o dossiê em duas grandes unidades. A primeira delas reúne os textos que examinam formas midiáticas de enunciação e o modo como elas movem esteticamente os anônimos, no enlace entre narrativa e sociedade. A segunda unidade possui seu ponto de coerência nas relações que os textos estabelecem entre mídia e manifestação.
On-Line Liquid and Gas Density Measurement-Advantages of Frequency Domain Transducers
Authors: Agar J. 
Published: November 2015

This paper discusses the advantages of frequency modulated transmission of information in plants, and how this philosophy is adapted in practice in the form of two instruments for on-line measurement of liquid and gas densities. The importance of measuring density is well appreciated for on-line blending and various forms of quality control applications, but special attention is drawn to its necessity in gas flow metering.
Designing Mechanised Aids to the Management of Production
Authors: Nutting David 
Published: November 2015

The control engineer of today is seemingly a man of many rare virtues and attributes: he combines practical realism with ingenuity; he is a man of vision and of high intellectual calibre. Given an understanding of his company's objectives and restraints, he can engineer a productive unit in conjunction with process and other specialists, to meet its target, on specification, on quantity, with safety and with the automatic generation and preparation of the necessary production statistics. In recent years several universities have followed the lead set by Cambridge with postgraduate and later, as at City University, first degree courses in control engineering. From the start BP has been a consistent supporter of these courses and several of the postgraduate trainees and ex-university apprentices, having read this relatively new subject, are in Control Engineering Branch. There they meet the intellectual challenge of applying the full power of modern technology on a broad front of the company's operations in production, refining and distributing. The control engineer's dream is not of automatons nor of refineries without human beings: he is concerned with giving refinery management a reliable mechanism through which to attain its objectives as efficiently as possible.
Principles, Practice and Problems
Authors: McGill R. J. 
Published: November 2015

Moisture content is one of the most important papermaking variables. Close control in the process is essential. Accurate knowledge of its absolute value, separated from that of solids, is highly desirable, for process and profit optimisation. A wide variety of measuring equipment and control methods is in use and several installations are described. Outstanding problems include the need to improve measurement reproducibility and independence from the effects of other variables, simplification of calibration and control, wet end measurement and cross-direction profile control. The ultimate aim should be an overall system for moisture and substance, incorporating distribution of measurement and control points throughout the process.
Fluid Dynamic Problems Awaiting Solution
Authors: Engel F. V. A. 
Published: November 2015

It is recommended that fluid dynamic problems related to specific phenomena of pulsating flow should be dealt with on the basis of non-dimensional parameters. Part I presents a survey of essential parameters. Recent research on self-induced pulsations and forced sinusoidal pulsating flow is reviewed. Investigation of the experimental results of these studies reveal crucial parameters, their correct choice and design. These few parameters are recommended as basic tools of analysis of more complex problems which are encountered in fluid flow measurement. In Part II peculiarities in flow and the behaviour of metering devices such as orifices, Venturis, or variable area flow meters are scrutinized. Some of these features, even under steady flow conditions, are not yet well understood. They should be fully explored in future studies as they may explain residual errors under pulsating flow conditions. Suggestions for future research are mainly concerned with flow conditions in the pipe line upstream of the metering device.
Process Gas Analysis in the Iron and Steel Industry by Mass Spectrometry
Authors: Schuy Klaus D. , Reinhold Bodo 
Published: November 2015

Advantages of applying mass spectrometry to the analysis of process gases in the iron and steel industry are: Only one instrument is required for the analysis of all process gas components of interest; These components are simultaneously and quantitatively analysed; The analysis speed is the same for all components, and is extremely high; The signal produced by any one gas component is linearly proportional to the concentration of that component; For complete analyses, the analyser requires very small amounts of sample and calibration gas; The gas analyser can also be used to check the calibration gases for impurities and to control their concentration ratios. After a brief discussion of mass spectrometer principles and instrumentation, some typical applications of mass spectrometer-based gas analysis systems as applied to the iron and steel industry are elucidated. The incorporation of a digital mini-computer results in an integrated, autonomous process gas analysis system, containing sampling and handling facilities, gas analyser, calibration setup and TTY data printout.
Holographic and Video Techniques Applied to Engineering Measurement
Authors: Butters J N , Leendertz J A 
Published: November 2015

In a brief period, lasers have developed from curiosities of the physics laboratory to tools suited to incorporation in complex instrumentation systems. One line of progress has been through the applications of holography and holographic interferometry to engineering metrology where the potential of a precision comparator is realized without a convenient means of using it. The process, however, has formed a basis for development and the progress of holographic metrology is reviewed leading to more general concepts better described as “Coherent Optical Metrology”. The authors' latest developments in this area are described where, by means of a coherent optical sampling technique, three dimensional data is coded onto an electronic video waveform. The method is based on speckle pattern interferometry with optical to electronic interfacing by means of a modified closed-circuit television arrangement. With this instrumentation, most of the measurement facilities of holography are retained without many of the inconveniences arising from photographic recording. The data is processed electronically and displayed or presented in a form suitable for viewing or to actuate a stage of process control.
Controller Design for Linear Multivariable Systems
Authors: Walker P H , Green J W 
Published: November 2015

A method of designing controllers for multivariable systems is described which regards the problem from an implicit reference model point of view. The rules for the design are found to be very simple to apply and involve only proportional and integral terms if all the system state variables are available. The method is demonstrated by means of two examples, one being a second order system with two inputs and two outputs, the other being a fourth order system also with two inputs and two outputs.
Mass Flow Metering
Authors: Wasson R. 
Published: November 2015

Mass flow measurement has many real advantages over volumetric measurement, particularly for gas flows. True and inferential methods of measuring mass flow are compared and true methods found to be significantly better. Of the different methods of measuring true mass flow, the axial flow transverse momentum method is shown to be particularly well suited to industrial application. A short outline of the history of the Black, Sivalls and Bryson Mass Flowmeter, which uses this principle, is given and it is shown that a very considerable amount of development and industrial trials were required before the meter achieved its present position where many large users of it are very satisfied with it. The results of extensive trials with the meter and of the subsequent use of 28 meters in ICI's Petrochemicals Division are presented and it is shown that the meters have given reliable service and shown good repeatability resulting in much improved material balances. The availability of suitable calibration facilities is reviewed and an indication given of likely further developments in this field.
Digital Simulation of the Steady State Behaviour of Moving Bed Processes;
Authors: Voskamp J. H. , Brasz J. 
Published: November 2015

A mathematical description of a complicated pellet indurating machine is presented that is simple and useful for digital computation and optimisation purposes. The arguments for some of the approximations used are given together with the resulting differential equations. A short discussion is devoted to some of the computational aspects. The verification of the model is described briefly, and typical computational results are presented from which some process conclusions are drawn. Although the process is specialised, the approach followed in this paper may be useful to other types of packed bed processes including sintering and drying of foods.

Signal Analysis and Intelligent Flowmeters
Authors: Higham E H , Fell R , Ajaya A 
Published: November 2015

In general, the instruments used for process measurement provide an acceptable level of performance, but there are occasions when the process operators suspect the integrity of the measurement signal and feel obliged to call on the instrument staff to check the span and zero of the transmitter. Quite apart from the cost of making such a test, experience shows that many of the transmitters checked in this way, and shown to be functioning correctly, subsequently become defective. Even if it were possible to devise a remotely controlled means for checking the span and zero, it is doubtful whether it could ever become a practical proposition. An entirely different approach is to use active sensors, such as resonant elements, in place of the traditional passive devices and to apply signal analysis techniques, which can be implemented by microprocessors. The measurement signal for these and other types of sensor can be derived from the time interval between successive zero crossings and this avoids the need for A/D conversion. Furthermore, analysis of the signal enables information regarding the status of the sensor as well as the operation of the associated process plant to be determined. This has been demonstrated by the application of these SFT to the signals generated by a turbine flowmeter.
Remote Boundary Pressure Control
Authors: Arden W J B , Cox C S 
Published: November 2015

In recent years the emphasis within British Gas PLC has moved from the construction aspects of the natural gas transmission system, to one of investigating methods of optimising the operational efficiency of the existing pipline network. In particular, the developments which have taken place in the area of microprocessor technology have provided the opportunity to implement improved control strategies in areas where existing pneumatic based systems are somewhat limited in terms of performance. This paper describes a problem associated with the control of pressure, at a remote point, which can be a considerable distance downstream from the main pressure regulating station. In addition, it illustrates how a series of simulation studies have enabled the evaluation of the revised control philosophy, quickly, efficiently and at minimal cost. This paper is based on previously published work entitled ‘Investigations into the Remote Pressure Control of Gas Transmission Pipelines’, by C S Cox, W J B Arden and I Fletcher. Presented at Int AMSE Conf ‘Modelling and Simulation’, Sorrento (Italy) Sept 29th-Oct 1st, 1986.
Challenging Areas in Flow Measurement
Authors: Kinghorn F C 
Published: November 2015

Flow measurement has many applications and a wide range of techniques is used. In many industrial sectors there are particular difficulties in measuring flowrate and often special solutions are required. Some of the problems in the oil and gas, biotechnology, automobile and water supply industries are described and the shortcomings or difficulties associated with the methods currently being used are identified. There are also numerous technical difficulties which span several industrial sectors and the topics of multi-phase flow, direct mass flow measurement, pipework configuration effects and computational fluid dynamics are covered, although it is recognised that these are only a few of a very much larger number of difficult areas.
Installation Effects on Vortex Flowmeters
Authors: Mottram R C , Rawat M S 
Published: November 2015

Most types of flowmeter are affected by flow disturbances caused by nearby pipe fittings. In the case of the vortex flowmeter, users currently have to rely on manufacturers' recommendations on minimum straight pipe lengths on either side of the meter as there are no relevant standards or codes of practice and little published experimental data. The paper presents some experimental results on the effects of upstream pipe roughness, single 90† bends, and pairs of 90† offset bends on the calibration in air of a vortex meter with a rectangular section bluff body. The results show that this particular vortex meter is sensitive to the roughness of the upstream pipework and required straight pipe lengths of about 55 diameters to avoid significant calibration changes caused by upstream bends. Installation lengths can be reduced by placing a flow straightener upstream of a meter particularly if the straightener-meter package can be calibrated as a unit. This concept has been explored using a Mitsubishi flow straightener with the vortex meter and promising results have been obtained with a package of 10 diameters overall length.
Recent Trends in Dental Caries in U.S. Children and the Effect of Water Fluoridation
Authors: Brunelle J.A. , Carlos J.P. 
Published: November 2015

The decline in dental caries in U.S. schoolchildren, first observed nationwide in 1979–1980, was confirmed further by a second national epidemiological survey completed in 1987. Mean DMFS scores in persons aged 5–17 years had decreased about 36% during the interval, and, in 1987, approximately 50% of children were caries-free in the permanent dentition. Children who had always been exposed to community water fluoridation had mean DMFS scores about 18% lower than those who had never lived in fluoridated communities. When some of the “background” effect of topical fluoride was controlled, this difference increased to 25%. The results suggest that water fluoridation has played a dominant role in the decline in caries and must continue to be a major prevention methodology.

Examples of relationships with various agencies involved with the criminal justice system are also described. The history of Synanon is described from its infancy to its present state as a multi-faceted, multi-million-dollar organization. The uniqueness of the Synanon Game is given credit for all these developments.
On the Evaluation of Treatments for Narcotics Addiction
Authors: Dole Vincent P. , Singer Burton 
Published: November 2015

This study is concerned with the domain of applicability of randomized clinical trials. For evaluation of well-defined treatments of acute diseases over limited periods of time, the randomized trial technique is unquestionably the best. However, in the field of chronic diseases (as illustrated by drug addiction) the physician's responsibility extends over periods of years, and his judgements involve consideration of many contingent factors which vary in the course of the disease. In this domain, randomized clinical trials, however ambitious in design, give only partial guidance. Observational data therefore must be used if treatment is to be optimized for individual patients. Two randomized trials in the treatment of narcotics addiction — one testing methadone and the other naltrexone — are reviewed, with comments on their conclusions and limitations.
Repeat follow-up Studies of 100 Young Norwegian Drug Abusers
Authors: Holsten Fred 
Published: November 2015

From 1971 to 1974, 100 young drug abusers were registered in a treatment program of a general mental hospital. Following treatment, the patients were personally interviewed by the author in 1975 and 1977. The aim of the project has been to study the adequacy of conventional psychiatric treatment of young drug abusers. Subgroups of patients with different developmental profiles in the observational period are analyzed. The reliability of one follow-up is tested against another follow-up approximately 3 years later.
The Application of Cost-Effectiveness Analysis to the Evaluation of Drug Abuse Prevention Programs: An Illustration
Authors: Hu Teh-Wei , McDonnell Nancy S. , Swisher John 
Published: November 2015

This paper represents a first step in the application of the principles of cost-effectiveness/cost-benefit analysis to primary drug abuse prevention programs. Four primary prevention programs, representative of the four program modalities, were selected as a basis for exploring the feasibility of applying the methodology and using existing data. The basic conclusion from this study is that cost-effectiveness/benefit evaluation is feasible for primary prevention programs. However, at the present time widespread use is constrained by the lack of proper control groups and the lack of drug-specific data at the program level.
