C. Wright Mills: A Political Writer and his Fan Mail
Authors: Sawchuk Kim
Published: August 2017

This paper examines the "fan mail" received by C. Wright Mills from his readership to better understand the reasons for Mills' popularity as a public intellectual in the 1950s. The paper documents Mills' strategic use of magazines and penny press publishers, his deployment of vernacular stylistic forms to express political issues, and the responses of these fans. These writerly readers not only lauded Mills' efforts but offered their constructive criticism and personal testimony, which Mills sometimes incorporated back into his speeches and articles. Many letter writers assisted in the circulation of Mills' texts within other informal networks, thus shedding light on the political conjuncture of the 1950s. The paper also attends to the methodological and epistemological challenge of using such letters, typically used to study responses to popular cultural texts, for the study of intellectual history.
Public Service Broadcasting as a Modern Project: A Case Study of Early Public-Affairs Television in Canada
Authors: Hogarth David
Published: August 2017

This study of public-affairs programs suggests that Canadian television hardly functioned as a modern disciplinary apparatus in its initial years. In the early 1950s, Canadian broadcasters sought to stake out and strategize a "middle ground" between U.K. (information) and U.S. (entertainment) TV, featuring public-affairs programs that Canadians would actually choose to watch in a more or less competitive North American broadcast market. However, newsmagazines and traditional long-form documentaries consistently violated the early pedagogical protocols of Canadian television and thus call into question conventional notions of public-service broadcasting.These shows and the controversies they generated should make us rethink Eurocentric theories about public-service broadcasting as a quintessential disciplinary machine.
Spatial Metaphor in the Work of Marshall McLuhan
Authors: Gow Gordon
Published: August 2017

Spatial metaphor is central to the layout and development of McLuhan's thought on culture and technology. This paper adapts a framework drawn from cognitive linguistics to describe how McLuhan's concepts of visual and acoustic space serve as structural, orientational, and ontological metaphors. In its ontological role, spatial metaphor provides the metaphysics for McLuhan's tetrad, which he came to regard as an alternative model for studying culture and technology.
Moralizing Uncertainty: Suspicion and Faith in Hitchcock's Suspicion
Authors: McCarron Gary
Published: August 2017

This paper presents a phenomenology of suspicion by way of a close reading of Alfred Hitchcock's 1941 film, Suspicion. The main argument of the paper is that suspicion is an interpretive strategy that can be used for making sense of situations that appear ambiguous or uncertain. In developing this argument, I claim that suspicion and faith are actually related interpretive experiences, a point that is articulated in the film although it is generally overlooked. Faith and suspicion may be equally paradoxical conditions, but they are essential strategies by which the world is interpreted and uncertainty is domesticated.
Trends in Canadian Newspaper Coverage of International News, 1988-2000: Editors' Assessments
Authors: Soderlund Walter C. , Lee Martha F. , Gecelovsky Paul
Published: August 2017

Between 1988 and 2000, a series of comprehensive surveys were administered to the editors of Canada's daily newspapers, in order to obtain their views concerning Canadian news reportage of international events. The 1995 data demonstrated an editorial perception of a marked decline in the quality and quantity of international news coverage. The 2000 data pointed to a partial recovery. Canadian editors, however, remain convinced that it is only in local news reporting that newspapers have a comparative advantage over other mass media. This study acknowledges the reversal that may have occurred following the events of September 11, 2001; the series will resume with the aim of charting editorial perceptions following those events.
Is There Any Social Cohesion in the Bulgarian Multicultural Society?
Authors: Varbanova Lidia , Dimitrova Anelia
Published: August 2017

Bulgarian society is multicultural and multiethnic, a fact very much linked with the historical and cultural roots of the country. The current paper outlines the main problematics linked with the concept of social cohesion in Bulgaria. Social cohesion is discussed in three main contexts: (1) cohesion for the sake of a national cause, where the unique "Chitalista" cultural and community system plays a key role; (2) reconciliation between ethnic groups, who live in peace and avoid conflicts; and (3) social stratification, difficult economic conditions, and absence of a middle class as serious burdens for building a cohesive society. The paper also discusses the role of voluntary organizations, media, and education in encouraging social cohesion in a time of democratic change.
Social Cohesion in the United Kingdom: A Case Report
Authors: Fisher Rod
Published: August 2017

Social cohesion is defined in, and adapted to, social policymaking in numerous ways. This paper attempts to clarify the definition with regard to the policymaking decisions of the U.K. government. In doing so, it brings to light the efforts of the 1998 Social Exclusion Unit government program that focused on recognizing how poverty grows in individual neighbourhoods, pointing out why neighbourhoods decline and how this could be prevented. The second phase of the program was to establish Policy Action Teams to fast-track policy thinking - including areas such as arts and sports - on the most serious issues within these neighbourhoods. From the Teams' reports, an interdisciplinary approach to social cohesion policymaking evolved. The paper also cites an attempt to benchmark the social impacts of the arts.
Cultural Consumption and Participation
Authors: Foote John
Published: August 2017

As technology-push and supply-side creativity help determine the shape of enhanced and more diverse cultural supply, new characteristics such as the potential of interactivity and multidirectional connections become questions of public policy and raise issues of consumer choice, accountability, and control. How equipped are we to monitor and understand the nature of these issues on a macro scale? This paper explores cultural consumption and participation patterns in Canada by reviewing recent quantitative analyses, identifying key data gaps, and proposing solutions. These include: (1) considering longer-range forecasts of consumer change; (2) conducting more international comparisons of consumer/participant-related research indicators; and (3) calling for more extensive theoretical and practical research focussed on the cultural consumer and participant.
The Policy of the City and Cultural Action
Authors: Mayol Pierre
Published: August 2017

Within the context of the Policy of the City and of Urban Social Development of the government of France, the paper discusses public cultural action (government involvement in cultural development), "emerging" cultures in housing projects and neighbourhoods that are supposedly "in trouble" (or, in other words, "sensitive" or "underprivileged"), and conflicts between community-based cultures and republican alternatives. In describing cultural conflict in urban situations, the paper refers to the situation in France. The article closes with a brief overview of certain developments in Europe.
Canada's Contribution to the "Management" of Ethno-Cultural Diversity
Authors: Henry Frances
Published: August 2017

It is often believed that Canada is able to "manage" its diverse society to the extent that it is cited as a model for other countries to follow. The main reason for this perception is that Canada is one of the very few countries to have legislated multiculturalism. Diversity and multiculturalism have, however, become sharply contested issues in Canadian society today as many people perceive them to be a threat to their traditional way of life. Moreover, this paper suggests that multiculturalism has, in fact, failed to control racism against ethno-racial minorities and that a stronger "radical" or "critical" multiculturalism is required for Canada to become an exemplar for other nations.
Tending to Society, Tending to Yourself: The Roles of Culture
Authors: Cheney Terry
Published: August 2017

This paper addresses the role that cultural activities may play in the lives of youth. First, it reviews the general roles that culture is argued to play in society. It then looks at a schema of communications in an individual's life, hinting at the roles culture may play in this and arguing that studying culture and youth is part of a more comprehensive research framework in order to place the particular role of culture and youth into a larger picture. It ends by reviewing concrete examples of research on youth and culture, highlighting existing strategic constraints and proposing the need for a more intensive and more broadly based research of the impacts of culture on individuals which would contribute to better understanding and, ultimately, more appropriate culture policies and programs.
Global Governance, Global Culture, and Multiculturalism
Authors: Krzysztofek Kazimierz
Published: August 2017

A pivotal change has occurred: the great national cultures no longer govern the circulation of culture worldwide. True, the larger nation states still maintain their "cultural diplomacy" machinery (though continually reducing the related expenditures), but their influence on the circulation of culture is next to negligible. High-powered economic mechanisms actually dictate the rules of the game. Hierarchical, central culture-peripheral culture relationships have been replaced by global culture-local culture relationships, with local cultures here standing for any identity-based culture (national, regional, etc.). This paper points out five responses of local cultures to globalization, factoring in both internal and international concerns, and in conclusion addresses the fragility of culture-related issues and the long road ahead toward maturation of a global consciousness.

The Economics of Cultural Policy in the Internet Age
Authors: Dayton-Johnson Jeff
Published: August 2017

This discussion takes both a cultural and economic perspective in looking at examples wherein reducing the Canadian Internet deficit would serve the public interest, and examines the prospects for addressing the deficit with public policy. The author suggests that the Internet is important for public policy because it is a medium for delivering the "cultural sector" of the economy. Policymakers, he argues, should take a lively interest in Canadian content on the Internet for the same reason that they have historically taken an interest in the country's cultural expression more generally. After addressing the issue of access, the paper asserts that there remains a solid economic justification for public support of arts and culture, including the Internet, and provides pragmatic reasons for an activist cultural policy.
Canadian Content: The Authorized Version
Authors: Dickenson Victoria
Published: August 2017

This article asserts that to make Canada's presence felt, we must understand the importance of the base-level information held by the country's preserving institutions (museums, libraries, and archives), and government must fund them to make their rich database content accessible on-line. The author suggests that Canada's meagre Internet presence can be strengthened by developing authoritative databases of Canadian literature, history, and art in full text, full image, or full audio and video format . Meanwhile, preserving agencies must abandon the notion that they are re-creating themselves in a virtual universe. Access to deep and authoritative content is what the next generation demands, not poor simulacrums of actual experience. This is the information that will transform and ultimately distinguish Canada's Internet presence.

When Is a Creationist Not a Creationist? Appreciating the Miracles of Public Opinion Polling
Authors: Brown Steven D. , Delodder James
Published: August 2017

This research report re-examines the claim made by the National Post newspaper just prior to the 2000 Canadian election that Canadians are split virtually down the middle on the merits of creationism versus evolution. Based on new data collected for the purpose, the authors argue that the original research likely overestimates the proportion of the population subscribing to creationist views. Moreover, they suggest that the nature of the question asked in the original research accounts for this overestimation. Finally, they argue that the increasing use of public polls for advocacy as well as descriptive purposes makes it imperative that the media and the public become more sophisticated in their appreciation of how the medium can affect the message.
Narratives of Schizophrenia: Constructing a Positive Identity
Authors: Schneider Barbara
Published: August 2017

This paper explores how people with schizophrenia construct positive identities in the face of the negative and stigmatizing discourse of mental illness. The author regards identity not as a fixed characteristic of individuals but rather as something actively constructed and reconstructed in communicative practice. By analyzing the narratives of people diagnosed with schizophrenia, the author shows that people with schizophrenia do not simply take up the negative meanings of schizophrenia provided by cultural discourses. Instead, they use various strategies in social interaction to construct positive identities and in doing so reinforce or reshape cultural knowledge about schizophrenia.
The Alberta SuperNet Research Alliance
Authors: Mitchell David
Published: August 2017

The Report of the National Broadband Task Force (2001) raised the prospect of extending broadband capability to virtually all Canadian communities within the next few years. The prototype for Canada as a broadband-connected nation is already under way in the province of Alberta, where, within the next two years, 95% of communities will be provided with broadband connectivity. It is expected that the Alberta SuperNet will provide these communities with higher levels of both government information and social services. It is unclear, however, how the network will impact such things as higher education, economic development, and cultural identity. This paper reports on a three-year federally funded research project studying the broad social impact of the SuperNet experiment.
L'ombudsman francaise de la Societe Radio-Canada : un modele d'imputabilite de l'information
Authors: Bernier Marc-Francois
Published: August 2017

In 1992, the Société Radio-Canada (SRC), French network of the Canadian Broadcasting Corporation, created an Office of the Ombudsman, mandated to address public complaints concerning journalistic practices. This article proposes first to better define the concept of journalistic accountability. After presenting a history of this function and giving an account of its relative scarcity, it describes the model of accountability set up at the SRC as revealed through an analysis of the annual reports from 1992-93 to 2000-01. Then it draws up a preliminary summary of the evolution of this form of journalistic self-regulation at the SRC.
Space, Time, and Communication Theory
Authors: Peters John Durham
Published: August 2017

This plenary address to the Laurier conference extends the fundamental insight of Innis and McLuhan that communication studies concerns time and space by inviting scholars to consider the very large and the very small, the very old and the very far, as outer limits to communication theory. Specifically, it explores geology, astronomy, and cosmology as inquiries into media that span deep time and deep space. It suggests that communication studies is not merely an interdisciplinary field, but one that goes beyond the human scale and potentially encompasses any inquiry into time and space. The untold expanse of communication is a territory, I contend, which we are only just beginning to appreciate.
A Tale of Two Stimulants
Authors: Hathaway Andrew D , Erickson Patricia G.
Published: August 2017

Cocaine and tobacco occupy opposite ends of a legal continuum that is narrowing due to diminishing acceptance of cigarette smoking and increasing restrictions on tobacco sales, use, and promotion. This paper compares Canadian newspaper coverage of the two drugs with reference to the main themes, information sources, and policy positions presented in the late 1980s and late 1990s. Further content analysis, of 1998-2002 opinion-editorials, documents recent developments in print media representations of the debates around use and control of these substances. Most notably, in contrast to earlier drug panics, the authors find a more sophisticated range of perspectives encroaching on the moral-legal distinctions and distortions that mark public discourse on all drugs.
Dispelling the Alphabet Effect
Authors: Grosswiler Paul
Published: August 2017

Canadian communication theory has accepted as one of its major tenets the superiority of Western civilization brought about by the phonetic alphabet. Challenges to the theory either have not been incorporated into the research literature or have been represented as working theories rather than conclusive evidence. This article seeks to help redress this imbalance by detailing the main claims of the alphabetic literacy arguments in the context of arguments advanced in several disciplines, suggesting that the alphabet effect theory should be dispelled. The article argues that a writing effect unites Western alphabetic and Eastern non-alphabetic cultures in a common heritage, and that historical periods of social advancement of the West and East have alternated in pendulum fashion. The article also introduces alternative views of the relationship between Eastern communication technologies, culture, and history to support the writing effect and pendulum model of the impact of communication technology in the East.
The 2003 Graham Spry Memorial Lecture: Toward a Human Right to Communicate?
Authors: Hamelink Cees J.
Published: August 2017

Current international human rights standards cover mainly the dissemination of information, the consultation of information, and the registration of information. Practically all human rights provisions refer to communication as the "transfer of messages." This reflects an outdated conception of communication as "distribution." Communication is interaction: a process of personal and public dialogue! The shift from distribution to interaction requires the adaptation of human rights standards to the new reality of global interactive technologies and the emergence of networking in many social domains.

Abstrak

Ibnu Jinny (Mosul, 322-329 H) Salah satu linguis Arab (Lughawiyun) yang sangat multitalend dan menguasai multidisiplin kelimuan Islam. Melalui masterpiece-nya “Al-Khashāish”, Ibnu Jinny mencoba membawa wacana dan diskusi-diskusi linguistik Arab dari yang semula terfokus pada perdebatan nahwu dan fanatisme mazhabnya kepada kajian-kajian yang lebih umum dan komprehensif. Bahasa, dalam pandangan Ibnu Jinny, bukan merupakan murni entitas rasional tetapi memiliki dimensi sosial, karena itu, metode, teori dan pendekatan yang digunakan pun mestilah menggabungkan keduanya. Jika teori linguistik Barat Modern memfokuskan obyek kajiannya pada empat unsur penting seperti; Fonetik, sintaksis, morfologi dan semantic, maka sesungguhnya tradisi linguistic Arab, meskipun belum tersistem secara terpadu jauh mendahului kajian mereka seperti yang dilakukan oleh Ibnu Jinny. Bahkan pendekatan sosiologis atau yang lain dapat kita telusuri dan dicari akarnya dari teori-teori Ibnu Jinni dan para linguis generasi setelahnya.

Abstract

Ibn Jinny (Mosul, 322-329 H) one of Arabic linguist was very multitalented and multidisciplinary master in Islamic scholarship. Through his masterpiece “Al-Khāshaish”, Ibnu Jinny tried to read discourse and discussion from the original Arabic linguistics that focused on the debate nahwu and fanaticism of his Mazhab in to studies of a more generally and comprehensively. Language, according to Ibn Jinny, is not a purely rational entity but a social dimension, therefore, methods, theories and approaches were used also must necessarily incorporate both dimensions. If the linguistic theory of Modern West focused on object of studies to four important elements such as; Phonetics (‘Ilm al-Ashwāt), Morphology (Sharf), Syntax (Nahw) and Semantics (‘Ilm al-Dilālah), then the Arabic linguistic tradition - as Ibn Jinny’s study - has led Western Linguist studies. Even the sociological approach or another we can browse and look for the roots of the theories of Ibn Jinni and linguists generations thereafter.

Analisa-se, neste trabalho, a relação dos coeficientes petrofísicos com a forma das curvas de fase e amplitude da função “condutividade espectral”(modelo de Dias), descritiva do comportamento elétrico de rochas que apresentam o efeito de polarização elétrica induzida (efeito IP, do inglês electrical “inducedpolarization” ). Inicia-se pelo desenvolvimento da função “condutividade de corrente total” do modelo e a conceituação do significado petrofísico de seus 5 parâmetros.As curvas geradas cobrem a totalidade das possibilidades oferecidas pelo modelo e mostram que podem existir até 2 picos na fase e até 3 patamares na amplitude dacondutividade. Esta versatilidade confere ao modelo um maior potencial para descrever dados experimentais. A análise detalhada das possíveis combinações de valoresentre os seus 4 parâmetros petrofísicos – sendo σ0 usado apenas como parâmetro de normalização da função σ – indica a influência de cada parâmetro na função e aexistência de correlação entre eles, assim como, mostra o grau de sensibilidade da função associado aos diversos intervalos de valores dos seus parâmetros.
Sondagem geoelétrica usada para investigar o espaço de acomodação dos sedimentos quaternários no estuário Jacuípe, Bahia, Brasil

Published: August 2017

O presente trabalho verificou o espaço de acomodação de sedimentos do estúario Jacúıpe, localizado no município de Camaçari, no litoral norte da Bahia.A técnica de sondagem elétrica vertical foi usada para interpretar as unidades litoestratigráficas que preenchem a referida área. O ambiente estudado se mostra controlado estruturalmente pela transição dos domínios tectônicos do embasamento cristalino e da sub-bacia do Recôncavo. Há indícios, apesar de incipientes, de que esse controle possa afetar, dramaticamente, a redução do espaço de acomodação estuarino, cenário opostamente relatado na literatura. As sondagens elétricas verticais revelaram que os pacotes sedimentares quaternários do estuário recobrem diretamente a sub-bacia do Recôncavo, o maior deles possuindo espessura de 20 m de areia. Foram determinados os volumes dos espaços de acomodação para diversos cenários estuarinos, dentre eles o arcabouço total durante o Holoceno, de 6,84 × 107 m3 e o espaço restante, de 6,67 × 106 m3. Este último valor comprovou o estado típico de um ambiente em avançado estágio de preenchimento, com apenas 9,89% dovolume inicial.
Identificação de assinaturas geofísicas de ambientes de ocorrência de formações ferríferas a partir da utilização de estatísticas multivariadas

Published: August 2017

A indicação de ambientes geológicos com maior possibilidade de ocorrência de mineralizações por meio de métodos indiretos é uma necessidade daindústria da mineração. Buscando eficiência, métodos abarcam uma grande gama de variáveis na sua execução, tornando-os complexos e extravagantes do pontode vista geológico e computacional. A utilização em conjunto de métodos radiométricos e magnetométricos, principalmente a combinação dos resultados do canal da contagem total com o sinal analítico, pode ser uma importante alternativa para inferir ambientes geológicos propícios a ocorrências de formações ferríferas com magnetita, especialmente nos casos onde as rochas encaixantes apresentam contraste em relação às rochas mineralizadas. Aplicando uma análise por principais componentes (PCA) sobre dados radiométricos e magnetométricos no estudo das mineralizações ferríferas da região de Curral Novo do Piauí, PI, obteve-se uma correlação linear de 0,99 entre a primeira principal componente e o canal radiométrico da contagem total. Esta concentração de informação pela redução de dimensionalidade mostra que a PCA faz sua função ao explicar, em uma principal componente, um conjunto de variáveis, em princípio, independentes. Com isso pode-se identificar, naquele ambiente geológico, assinaturas particulares de zonas mais propícias à ocorrência de formações ferríferas com base nos dados de contagem total e do sinal analítico.
AREAL SURFACE CHARACTERIZATION OF ACID-FRACTURES IN CARBONATE ROCKS
Authors: Ferreira Rodrigues Valdo , Araujo Victor Rodolfo , Wellington Campos , Medeiros Ana Catarina da Rocha
Published: August 2017

Fracture surface characteristics have significant effect on fracture hydraulic conductivity. The available acid-fracture conductivity correlations do notconsider surface characteristics or make an incipient use of it. A proper description of the acid-fracture surfaces is the initial step towards the right consideration of surface roughness in hydraulic conductivity. This paper presents an areal (3D) surface evaluation of acid-etched fractures, simulated in samples taken from whole cores of an oil producer limestone. The topography of acid-fractured surfaces was assessed using a laser profilometer. The surfaces were evaluated with a set of 3D surface parameters. The results showed that the main features of acid-etched surfaces are large roughness, negative skewness, high kurtosis, and intermediate isotropy, mostly random, but with some spatial orientation. The acid-fractured surfaces can be represented by the rms height, which showed great linear correlation with most of the surface parameters. The parameters texture aspect ratio, bearing index, valley retention index, and density of summits showed low correlation with rms height. A method to calculate fracture width from surface topography was developed. An attempt to explain abnormal behavior in initial conductivity tests revealed the potential use of surface characterization for management of fine particles in oil and gas reservoirs. It is suggested to search improved fracture conductivity correlation through the relationship between lab measured conductivities and surface characterization parameters.
APPLICATION OF MULTICHANNEL ANALYSIS OF SURFACE WAVES METHOD (MASW) IN AN AREA SUSCEPTIBLE TO LANDSLIDE AT UBATUBA CITY, BRAZIL
Authors: Lima Júnior Sérgio Bezerra , Prado Renato Luiz , Mendes Rodolfo Moreda
Published: August 2017

This paper presents results from the MASW method (multichannel analysis of surface waves) in a hill side area of unsaturated soils in the Ubatuba City,Brazil, a site where numerous mass movements have occurred. It discusses the influence of some acquisition parameters, such as, the natural frequency of geophones and minimum and maximum offsets in dispersion image results and does a comparative analysis of the results obtained in repeated tests carried out in the same place, under the same conditions, during the dry and rainy seasons. The comparative analysis for the inversion results in different periods showed that the values of S-wave velocity during the dry season were higher than those for the rainy season; these variations were attributed to the higher cohesion of the soil structure in the dry season. The final 1D velocity profile model with depth was consistent with the results of other geophysical and geotechnical investigations made. Although additional in situ and laboratory geotechnical tests, are necessary (to obtain soil parameters such as hydraulic conductivity, moisture content, soil suction, for example), for a complete characterization of the geotechnical properties of the investigated soil, the result shows that it is possible to use empirical correlations between the Vs profile, from the MASW method, and soil stiffness parameters in order to monitor areas susceptible to landslide.
A MATHEMATICAL MODEL FOR WIRELINE LOGS FILTERING USING DIFFERENTIAL FUZZY PARAMETERS
Authors: Guerra Carlos Eduardo , Andrade André José Neves , Lima Ivnon José de Farias
Published: August 2017

Signal processing is a set of techniques used to extract data from any signal. A signal may be mathematically characterized as a function of several variables (parameters), such as time, distance, resistivity, or radiance. A signal is usually acquired using one or more analog or digital devices, such as a temperature sensor, a digital camera, or a resistivity probe. After acquisition, the processing depends on the nature of the signal and its information. In addition to the information being studied, the recorded signal may contain noise, which hinders the extraction of information, leading to ambiguous or erroneous results. The objective of this study is to present a non-linear technique for noise attenuation in well logs using fuzzy sets and fuzzy logic. The proposed filter evaluates the continuity of the log measurements through the use of two differential parameters. Sudden leaps in the measurements may indicate the presence of noise; therefore, for each point in the log, the filter evaluates the degree of discontinuity and provides a correction value to be applied. Differential fuzzy filtering is applied to data from synthetic and real well logs to conduct a performance evaluation using the MSE (mean square error).

Buscando maior eficiência e rapidez na descoberta de novos alvos prospectivos de rochas sedimentares fosfáticas, foi realizado o processamento dos dados aerogeofísicos juntamente com a correlação estatística dos dados geoquímicos. A integração destes dados proporcionou alvos potenciais que serão investigados com mapeamento geológico e geofísica terrestre (gamaespectrometria) para produzir parâmetros de calibração e comparação com as informações de geofísica aérea. A integração de informações geológicas e mapas de estimativa de eU e P mostraram que rochas ígneas e crostas lateríticas apresentam os teores mais altos de eU e eTh, conforme esperado. Entretando foram identificadas anomalias com pequeno comprimento de onda nos sedimentos das formações Serra de Santa Helena e Sete Lagoasdo Grupo Bambuí, onde são conhecidas ocorrências de corpos fosfáticos na área. O próximo passo deste trabalho será a investigação em campo destas anomalias encontradas, por meio de perfis geológicos e gamaespectrometria terrestre. ABSTRACT. The project area is located in the central part of Brazil, on the northeast region of Goiás State. The phosphatic rocks occur in the Bambuí Group, on the eastern portion of the Faixa de Dobramentos Brasília – Brasília Fold Strip (FDB), on the western border of the São Francisco Craton. In the area under investigation, themineralized rocks are associated with limestone and apatite. In order to discover new prospective targets of phosphatic sedimentary bodies, a faster and more objective airborne geophysics data processing method was carried out together with statistical correlation of geochemical data. The integration of these data identified potential mineralized targets to be checked with geologic mapping and ground geophysics (gamma-ray spectrometry) to produce a parameter of calibration and comparison with the airborne geophysical information. Integration of geologic information and estimate maps of eU and P shows that igneous rocks and lateritic crusts present the high estgrades of uranium and thorium elements, as expected. However, short wave length anomalies were identified in sediments of the Serra de Santa Helena and Sete Lagoas formations (Bambuí Group), where known phosphatic bodies occur in the studied area. The next step of this work will be field work to check these anomalies, with geological mapping and ground gamma-ray profiles.Keywords: applied geophysics, multiple regressions, phosphorites, uranium, Bambuí Group.
GROUND ROLL ATTENUATION USING SHAPING FILTERS AND BAND LIMITED SWEEP SIGNALS
Authors: Santos Quézia C. dos , Porsani Milton José
Published: August 2017

Os dados sísmicos terrestres, geralmente, apresentam baixa razão sinal-ruído devido, entre outros fatores, à presença deground roll, um ruído caracterizado por eventos coerentes e lineares, com altas amplitudes, baixas frequências temporais e baixas velocidades e, na maioria dos casos, dispersivos, que se sobrepõem àsreflexões, prejudicando o processamento e a interpretação dos dados. Quando a tentativa de atenuar oground roll durante a aquisição dos dados (utilizando arranjos de fontes e receptores) falha, diversos métodos podem ser empregados no processamento. Neste trabalho, discute-se um método de filtragem baseado no filtrode forma de Wiener, sua implementação e seus principais parâmetros. Também é apresentada uma variante do método, baseada no algoritmo de deconvolução direta. Os resultados da aplicação da filtragem direta em dados sísmicos reais são bastante satisfatórios, quando comparados com aqueles obtidos com os métodos convencionais FK e corta-baixas. ABSTRACT: Onshore seismic data often have low signal to noise ratio due to, among other factors, the presence of ground-roll, a noise characterized by coherent,linear and dispersive events with high amplitudes, low frequencies and velocities. This noise overlaps with reflections, hindering the data processing and interpretation.When the attempts to reduce the ground-roll during data acquisition (using source and receiver arrays) fail, several methods can be used in seismic processing. Herewe discuss a filtering method based on Wiener shaping filter, its implementation and its main parameters. We also present a different approach based on the directdeconvolution algorithm. The results of the application of direct methods to a real seismic data set are quite satisfactory when compared with those obtained withconventional FK and low-cut filters.Keywords: ground roll, shaping filters, seismic data processing.

Additives for processing natural rubber and their application in small rubber plantations
Authors: Peláez Arroyave Gabriel Jaime , Velásquez Restrepo Sandra Milena , Giraldo Vásquez Diego Hernán
Published: August 2017

Se presenta una revisión de literatura sobre cómo los aditivos usados en los procesos de beneficio del caucho natural modifican las propiedades del látex líquido o caucho seco en forma de láminas o coágulos, productos que pueden obtenerse en plantaciones de caucho como las que abundan en Colombia. Se consideran las ventajas y desventajas del uso de los aditivos, resaltando la disminución del impacto ambiental y suministrando criterios para reemplazar sustancias tradicionalmente usadas pero que implican riesgos para la salud. Se encontraron pocas investigaciones cuyo objetivo principal fuera evaluar el efecto de los aditivos empleados durante el beneficio en las propiedades del látex líquido o el caucho sólido. Se recurrió, por lo tanto, a identificar en los estudios dedicados al procesamiento del caucho natural aquellas secciones que tratan el efecto de los aditivos en las propiedades del látex o del caucho sólido. Se identificó una marcada tendencia para eliminar total o parcialmente el uso de amoníaco como estabilizante del látex, y para usar sustancias naturales como algunos vinagres para reemplazar los ácidos fórmico y acético en el proceso de coagulación del látex fresco. Estas son alternativas viables para ser implementadas en los procesos que se llevan a cabo en pequeñas plantaciones de caucho de Colombia.
