Wanapum Overview and Perspectives Developed During Tribal Narrative WorkshopThe Wanapum Tribe, Stoffle, Richard, Arnold, Richard 06 1900 (has links)
The Greater than Class C (GTCC) Environmental Impact Statement (EIS) evaluated the potential impacts from the construction and operation of a new facility or facilities, or use of an existing facility, employing various disposal methods (geologic repository, intermediate depth borehole, enhanced near surface trench, and above grade vault) at six federal sites and generic commercial locations. For three of the locations being considered as possible locations, consulting tribes were brought in to comment on their perceptions on how GTCC low level radioactive waste would affect Native American resources (land, water, air, plants, animals, archaeology, etc.) short and long term. The consulting tribes produced essays that were incorporated into the EIS and these essays are in turn included in this collection. This essay was produced by the Wanapum Tribe for the Hanford Site.

A Constant Conduction Angle Biased RF Power Amplifier for Improved Linearization in Class C OperationLacaille, Greg 01 June 2010 (has links) (PDF)
Class C power amplifiers offer higher efficiency than class B power amplifiers, but suffer from poor linearity. A feedback based biasing system to improve the linearity of a class C power amplifier is designed. A class B amplifier with a gain of 20 dB and 20 MHz bandwidth at 900 MHz acts as the launching point for the design. The biasing and output network of the class B power amplifier is modified to produce a class C amplifier at conduction angles of 180°, 162°, 126°, 90°, and 54°. A feedback based biasing system, which uses two matched and scaled down transistors, compares the DC current of a class B and a class C biased transistor. This comparison is used to control the biasing voltage of the amplifier. The performance for each class C amplifier is simulated with the proposed constant conduction angle biasing (CCAB) system. The conduction angle, transducer gain, operational gain, VSWR, and drain efficiency are measured from simulation for each of the 5 normally biased and 5 CCAB amplifiers. Dynamic ranges of over 8 dB are demonstrated for the CCAB amplifiers. The effects of loop gain, temperature, and operating frequency for the 126° amplifier are simulated. The 3rd order intermodulation products of a 10 MHz AM modulated 900 MHz signal are compared for the 126° normally biased and CCAB biased amplifier as well as the class B amplifier. The difference between the fundamental and the 3rd order intermodulation products is shown to improve from 9.9 dB for the normal class C to 28.7 dB for the CCAB amplifier.

A influência da publicidade televisiva no consumo da população de classe C: os anunciantes do varejo popularMonte, Michele Helena Lopes Del 03 November 2011 (has links)
Este é um estudo sobre a relação entre os componentes da publicidade criada para a veiculação em televisão e seus efeitos sobre o comportamento do consumidor. A publicidade, como tema de estudo, foi abordada sob os aspectos da influência e da persuasão, observadas pela ótica dos estudos das Teorias dos Efeitos da Comunicação Social e do Comportamento do Consumidor. Pela amplitude do tema escolhido, fizemos um recorte, escolhendo a observação da publicidade televisiva de grandes redes varejistas de móveis e eletroeletrônicos, por seus imensos investimentos em publicidade e pela enorme fatia que ocupam nos intervalos da programação de TV. Os resultados da persuasão publicitária são expressos no comportamento do consumidor, e para isso escolhermos observar um consumidor em particular, os consumidores pertencentes à classe C, fatia da população que cresceu rapidamente na última década, e cuja importância mostrou-se evidente, por seu poder de compra e tomada de crédito, que aquecem a economia do país. Além da pesquisa bibliográfica, a pesquisa emprega diferentes metodologias. Para o entendimento de aspectos ligados à persuasão publicitária, empreendemos a análise sistemática de anúncios, observando seu conteúdo imagético, sonoro e discursivo. A partir dos resultados dessa análise, elaboramos um roteiro de entrevistas em profundidade e questionamos consumidores de classe C quanto aos efeitos daquilo que eles puderam observar nessa publicidade. Os resultados finais mostraram que a publicidade de redes varejistas de móveis e eletroeletrônicos possuem características próprias que a identifica como tal. Também foi possível constatar a relação entre a composição dos anúncio e seu caráter persuasivo, expresso no comportamento dos consumidores e observado por meio das entrevistas em profundidade. Outros aspectos, relacionados aspectos da cognição - contexto da informação, memória, pré-ativação (priming), medição da atenção e da importância de atributos também puderam ser avaliados, bem como pudemos discutir, a partir dos resultados, algumas das teorias do Comportamento do Consumidor. / This is a study on the relationship between the components of advertising created for broadcasting on television and its effects on consumer behavior. Advertising, as a subject of study was approached from the aspects of influence and persuasion, observed by optical studies of Theories of the Effects of Media and Consumer Behavior. Amplitude of the theme, we made a cut, choosing the observation of television advertising of large retailers of furniture and electronics, for its huge investments in advertising and the huge chunk that occupy the intervals of TV programming. The results are expressed persuasion advertising on consumer behavior, and for that we choose to observe a consumer in particular, consumers belonging to the class C, the portion of the population that grew rapidly in the last decade, and whose importance was evident, by his power of purshaseand and to make loans, which boost the economy. In addition to the literature, the research employs different methodologies. For the understanding of aspects of advertising persuasion, we undertook a systematic analysis of ads, noting its contents imagery, sound and discursive. From the results of this analysis, we developed a script in-depth interviews and question C-class consumers as to the effects of what they could observe in the advertising. The final results showed that advertising for retailers of furniture and electronic characteristics that are identified as such. It also appeared the relationship between the composition of the ad and their persuasiveness, as expressed in consumer behavior and observed by means of interviews. Other issues related aspects of cognition - the context of information, memory, preactivation (priming), measurement of attention and importance of attributes could also be evaluated, as well as we discuss, from the results, some of thebehavior consumer theories.

Metabotropic Glutamate Receptor 2 Activation: Computational Predictions and Experimental ValidationEllaithy, Amr 01 January 2018 (has links)
G protein-coupled receptors (GPCRs) are the largest family of signaling proteins in animals and represent the largest family of druggable targets in the human genome. Therefore, it is of no surprise that the molecular mechanisms of GPCR activation and signal transduction have attracted close attention for the past few decades. Several stabilizing interactions within the GPCR transmembrane (TM) domain helices regulate receptor activation. An example is a salt bridge between 2 highly conserved amino acids at the bottom of TM3 and TM6 that has been characterized for a large number of GPCRs. Through structural modeling and molecular dynamics (MD) simulations, we predicted several electrostatic interactions to be involved in metabotropic glutamate receptor 2 (mGlu2R) activation. To experimentally test these predictions, we employed a charge reversal mutagenesis approach to disrupt predicted receptor electrostatic intramolecular interactions as well as intermolecular interactions between the receptor and G proteins. Using two electrode voltage clamp in Xenopus laevis oocytes expressing mutant receptors and G-proteins, we revealed novel electrostatic interactions, mostly located around intracellular loops 2 and 3 of mGlu2R, that are critical for both receptor and G-protein activation. These studies contribute to elucidating the molecular determinants of mGluRs activation and conformational coupling to G-proteins, and can likely be extended to include other classes of GPCRs.

Previous issue date: 2018-04-04 / Created by market operators in period of economic ascension in Brazil, starting in the 2000s, the
term Class C is an economic classification developed with the purpose of a segmental of a new
form of consumers. This time this paper aims to understand how the class c, constructs the notion
of citizenship through consumer goods, especially consumption in shopping malls. To achieve this
aim, the object of the study is based on the investigation and understanding of the collection of
meanings that the consumer / citizen uses to decide for a mall of his / her preference. It research
field of this work is Buriti Shopping Center, an enterprise located in Aparecida de Goiânia -
metropolitan region of the city of Goiânia, Goiás. In addition to the issues related to the
consumption of merchandise, citizens of class c, perceive Buriti Shopping in its multiple urban and
geographical interventions, as far as the region around them. Consumption, in turn, as a mechanism
that produces communicative acts for malls, especially directed to class c, in order to project in the
citizens' imagination the idea of everyday practices shaped by a receptive, comfortable, safe, clean
public-private environment and indifferent to the mishaps of the city around it, is therefore an
important item of analysis of this work. For this purpose, we will walk through the historical
trajectory of shopping malls, from its emergence in nineteenth-century Europe to its expansion and
development in the postwar United States, and in Brazil from the 1960s onwards. In addition,
supporting us in the studies of Giddens (1985); Bourdieu (2008); Souza (2012); Dubar (2009); Hall
(2011); Jameson (1993); Baudrillard (1981, 1997); Slater (2002); Featherstone (1995); Morin
(1969); Castells (1999), we present the concepts that underlie the theories about Classes; Habitus;
Belonging; Decentralization; Identity; Postmodernity; Consumer society; Consumer Culture; Mass
Culture and Information Society. Based on qualitative and quantitative empirical research whose
objectives are to identify the notion of citizenship by consumers in Buriti Shopping customers - in
order to answer the guiding question of this study: the consumer of class c, considers the "
consumption "as a means of legitimizing citizenship? The results obtained in the analyzes indicate
that the citizen does not feel more citizen when consuming. Although citizenship and consumption
are intertwined, consumption is shaped by a condition of who is already a citizen. Therefore, the
role of legitimizing citizenship is not attributed to consumption. From this perspective, for citizens
of class c, citizenship is a pre-existing condition of life, with citizenship being linked or not with
consumption activity. / Criado pelos agentes de mercado no período de ascensão econômica no Brasil a partir dos anos
2000, o termo classe C, é uma classificação socioeconômica difundida com o propósito de
segmentar uma nova modalidade de consumidores em potencial. Desta feita, este trabalho tem por
objetivo compreender como a classe C constrói a noção de cidadania por meio dos bens de
consumo, sobretudo do consumo em shopping centers. Para atingir este fim, o objeto do estudo
sustenta-se na investigação e compreensão da coleção de significados que o consumidor/cidadão
utiliza para decidir por um shopping center de sua preferência. O campo de pesquisa de
investigação deste trabalho é o Buriti Shopping Center, empreendimento situado no município de
Aparecida de Goiânia – região metropolitana da cidade de Goiânia, Goiás. Para tanto, além das
questões vinculadas ao consumo de mercadorias, almeja-se também identificar como os cidadãos
de classe C percebem o Buriti Shopping em suas múltiplas intervenções urbanas e geográficas, no
que concerne a região à sua volta. O consumo, por sua vez, enquanto mecanismo que produz atos
comunicativos para os shoppings, especialmente direcionadas para a classe C de modo a projetar
no imaginário dos cidadãos a ideia de práticas cotidianas moldadas por um ambiente público-
privado receptivo, confortável, seguro, limpo e indiferente aos percalços da cidade ao seu redor,
constitui, portanto, importante item de análise deste trabalho. Para tanto, percorreremos a trajetória
histórica de shopping centers, do seu surgimento na Europa do século XIX até a sua expansão e
desenvolvimento nos Estados Unidos do pós-guerra, e no Brasil, dos anos 1960 em diante. Além
disso, nos sustentando nos estudos de Giddens (1985); Bourdieu (2008); Souza (2012); Dubar
(2009); Hall (2011); Jameson (1993); Baudrillard (1981; 1997); Slater (2002); Featherstone
(1995); Morin (1969); Castells (1999), apresentamos os conceitos que fundamentam as teorias
acerca de Classes; Habitus; Pertencimento; Descentramento; Identidade; Pós-modernidade;
Sociedade de Consumo; Cultura de Consumo; Cultura de Massa e Sociedade Informacionalista.
Tendo como base a pesquisa empírica de caráter qualitativo e quantitativo cujos objetivos é
identificar nos clientes – frequentadores do Buriti Shopping - a noção de cidadania pelo consumo,
de modo a responder à pergunta norteadora deste estudo: o consumidor de classe C considera o
“consumo” como meio legitimador da cidadania? Os resultados obtidos nas análises indicam que o
cidadão não se sente mais cidadão quando consome. Embora cidadania e consumo estejam
entrelaçados, o consumo se configura por uma condição de quem já é cidadão. Portanto, não é
atribuição do consumo o papel de legitimar a cidadania. Por este prisma, para os cidadãos de classe
C a cidadania é uma condição de vida preexistente, estando a cidadania ligada ou não a atividade
de consumo.

Constant Conduction Angle Biasing for Class C Monolithic RF Power AmplifiersRai, Gursewak Singh 01 November 2012 (has links)
In modern wireless communication systems, a base station typically serves a few hundred users within its cell coverage. To combat the near-far problem – the situation where a nearby user’s strong cellular signal masks the cellular signal of a faraway user – base stations continually enforce power control. That is, nearby users must lower their transmit power. In CDMA technology, power control can be as large as 70-80dB. At low power outputs, this greatly impacts the performance of the RF power amplifier (PA) in the cellular device. For small RF drives, the magnitude of the output RF current approaches the magnitude of the DC current and thus the efficiency suffers. Operating the RF PA in class C operation improves the efficiency, but results in poor linearity.
Several methods of so-called dynamic biasing have been proposed. These strategies entail lowering the bias of the PA as the RF drive increases. The proposed methods, however, fail to explain how to achieve linearity and low third-order intermodulation distortion. Additionally, the methods utilize open-loop implementations.
This work presents a novel dynamic biasing topology that results in a much improved linear class C PA. The topology utilizes a closed loop that cleverly senses the operating conditions of the "power device." Particularly, the loop operates on the principle of keeping the conduction angle remarkably constant and thereby ensuring linearity. The work details a thorough design methodology that should provide assistance to a designer wanting to implement the topology in an RF integrated circuit. Agilent ADS simulations and laboratory results from a functional PCB prototype bring merit to the topology.

Diffusivity and resistance to deterioration from freezing and thawing of binary and ternary concrete mixture blendsBeck, Lisa Elanna January 1900 (has links)
Master of Science / Department of Civil Engineering / Kyle Riding / Corrosion of reinforcing steel is one of the most common and serious causes of
reinforced concrete deterioration. While corrosion is normally inhibited by a passive layer that
develops around the reinforcing steel due to the high pH environment of the surrounding
concrete, chlorides will break down this protective layer, leading to reinforcement corrosion.
Decreasing the diffusivity of the concrete would slow the ingress of chlorides into concrete, and
is one of the most economical ways to increase the concrete service life.
Optimized concrete mixtures blending portland cement and supplementary cementing
materials (SCMs) have become popular throughout the construction industry as a method of
improving both fresh and long-term concrete properties such as workability, strength and
porosity. It has been shown that use of Class F fly ash, silica fume and ground granulated blast
furnace slag (GGBFS) in binary concrete mixture blends can result in a significant reduction in
concrete diffusivity. This study investigates the ability of Class C fly ash and ternary concrete
mixture blends to also aid in diffusivity reduction. In order to study the effect of incorporation of
SCMs into concrete, mixtures containing Class C and Class F fly ash, silica fume and GGBFS
were tested following the ASTM C 1556 procedures to measure the concrete’s apparent chloride
diffusivity. Structure life cycles were modeled using the measured apparent chloride
diffusivities with two finite-difference based life-cycle analysis software packages. To
determine whether a correlation between diffusivity and deterioration due to freezing and
thawing exists, samples were also tested for their ability to resist deterioration from freezing and
thawing cycles using a modified ASTM C 666 Procedure B test.
Results show that the use of Class C fly ash yields some service life improvements as
compared to the portland cement control mixtures, while ternary mixture blends performed
significantly better than the control mixture and equal to or better than the binary SCM mixtures
tested. Freeze-thaw tests showed all mixtures to be equally resistant to deterioration due to
freezing and thawing.
