description: Molecular Docking and complete quantum chemical studies of 1-{[(Z)-Cyclopentylidene] amino}-3-phenylthiourea have been done by using DFT/ B3LYP method and 6-311 G (d, p) as the basis set. We have compared optimized geometry of title molecule with experimental data. A detailed interpretation of the vibrational assignments of title molecule is reported. Molecular Electrostatic Potential (MESP) generated by a chemical species is widely used as a tool for exploring its properties and locating potential sites for interaction with other moieties. Nonlinear optics (NLO) is the branch of optics that describes the behavior of materials in nonlinear media. In quantum chemistry, a natural bond orbital or NBO is a calculated bonding orbital with maximum electron density. Time-dependent density functional theory (TDDFT) is a quantum mechanical theory used in physics and chemistry to investigate the properties and dynamics of many-body systems in the presence of time-dependent potentials, such as electric or magnetic fields.The electronic properties of title molecule are discussed with help of molecular FHOMO, FLUMO composition, band gap, and MESP plots. The NLO, NBO, UV spectra of title molecule also calculated with same level of theory. Some biological parameter Log P and Log S are also calculated which suggests that the title molecule have good ability to deliver drugs in various diseases.
Against all odds? Forming the planet of the HD196885 binary

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: HD196885Ab is the most "extreme" planet-in-a-binary discovered to date, whose orbit places it at the limit for orbital stability. The presence of a planet in such a highly perturbed region poses a clear challenge to planet-formation scenarios. We investigate this issue by focusing on the planet-formation stage that is arguably the most sensitive to binary perturbations: the mutual accretion of kilometre-sized planetesimals. To this effect we numerically estimate the impact velocities $dv$ amongst a population of circumprimary planetesimals. We find that most of the circumprimary disc is strongly hostile to planetesimal accretion, especially the region around 2.6AU (the planet's location) where binary perturbations induce planetesimal-shattering $dv$ of more than 1km/s. Possible solutions to the paradox of having a planet in such accretion-hostile regions are 1) that initial planetesimals were very big, at least 250km, 2) that the binary had an initial orbit at least twice the present one, and was later compacted due to early stellar encounters, 3) that planetesimals did not grow by mutual impacts but by sweeping of dust (the "snowball" growth mode identified by Xie et al., 2010b), or 4) that HD196885Ab was formed not by core-accretion but by the concurent disc instability mechanism. All of these 4 scenarios remain however highly conjectural.

Disentanglement and Decoherence without dissipation at non-zero temperatures

description: Decoherence is well understood, in contrast to disentanglement. According to common lore, irreversible coupling to a dissipative environment is the mechanism for loss of entanglement. Here, we show that, on the contrary, disentanglement can in fact occur at large enough temperatures $T$ even for vanishingly small dissipation (as we have shown previously for decoherence). However, whereas the effect of $T$ on decoherence increases exponentially with time, the effect of $T$ on disentanglement is constant for all times, reflecting a fundamental difference between the two phenomena. Also, the possibility of disentanglement at a particular $T$ increases with decreasing initial entanglement.

description: An attempted synthesis of 5-aryl-6,7-dihydrodibenzo[b,j][1,10]phenanthroline derivatives from 2,3-dihydroacridin-4(1H)-ones with 2-aminocarboxylic acid derivatives in presence of phosphorus oxychloride at 130˚C yielded a novel class of quin[1,2-b]acridine derivatives. The newly synthesized compounds showed a better cytotoxic activity against HeLa and MCF-7 cell lines during the structure–activity relationship (SAR) studies. To discover with the interactions of these molecules, we carried out molecular docking studies using the human protein kinase CK2 inhibitors. The molecular interaction results provided a number of elegant information for the outlook design of more potent inhibitors.

description: We show that solitons undergo a strong blue shift in fibers with a dispersion landscape that varies along the direction of propagation. The experiments are based on a small-core photonic crystal fiber, tapered to have a core diameter that varies continuously along its length, resulting in a zero-dispersion wavelength that moves from 731 nm to 640 nm over the transition. The central wavelength of a soliton translates over 400 nm towards shorter wavelength. This accompanied by strong emission of radiation into the UV and IR spectral region. The experimental results are confirmed by numerical simulation.

description: No biénio 1974-1975 a Rádio Renascença foi palco de um dos confrontos ideológicos de maior visibilidade na sociedade portuguesa. Profundamente enraizado nas lutas travadas pelo controlo dos meios de comunicação, o caso da Rádio Renascença teve a particularidade de funcionar como um sinal de alarme para a grande maioria dos portugueses, a quem o projecto colectivista não seduzia. Por outro lado, tratando-se de um media da Igreja, a ocupação da Emissora Católica levou a tomadas de posição do Episcopado que em muito contribuíram para definir o rumo dos acontecimentos em direcção ao 25 de Novembro. É este contributo da Rádio Renascença para a evolução política pós-revolução que se procura explicitar no presente artigo.

description: The prisoner's dilemma (PD) game is a simple model for understanding cooperative patterns in complex systems consisting of selfish individuals. Here, we study a PD game problem in scale-free networks containing hierarchically organized modules and controllable shortcuts connecting separated hubs. We find that cooperator clusters exhibit a percolation transition in the parameter space (p,b), where p is the occupation probability of shortcuts and b is the temptation payoff in the PD game. The cluster size distribution follows a power law at the transition point. Such a critical behavior, resulting from the combined effect of stochastic processes in the PD game and the heterogeneous structure of complex networks, illustrates the diversity of social relationships and the self-organization of cooperator communities in real-world systems.
Os meios católicos portugueses perante a guerra colonial: reconfigurações da questão religiosa

Year: 2000

description: Neste artigo o autor procura demonstrar a relação estabelecida entre os posicionamentos dos católicos em face da Guerra Colonial, desencadeada entre o Estado Português e os Movimentos de Libertação de Angola, Moçambique e Guiné, e a reconfiguração da questão religiosa na sociedade portuguesa desde finais de 50 até às vésperas da transição democrática, em 1974. A compreensão da trajectória desenvolvida entre uma postura de legitimação e a constituição gradual de focos de contestação remete para a desvalorização de um modelo unitário do catolicismo e com pretensões hegemónicas sobre a sociedade, no qual a intervenção política se encontrava vedada, e a consequente percepção do catolicismo como espaço plural, cuja articulação com sectores sócio-culturais é geradora de posturas políticas diferenciadas. Nalguns meios católicos, a valorização do exercício da cidadania, relacionada com a percepção de um contexto de laicidade na sociedade portuguesa, culminou na reivindicação da liberdade e da democracia políticas.

Loss of miR-143 and miR-145 inhibits hematopoietic stem cell self-renewal via dysregulated TGF-beta signaling
Creators: name: Lam, Jeffrey Churk-Hang
Publisher: name: University of British Columbia
Year: 2016

description: Myelodysplastic syndromes (MDS) are a collection of hematopoietic malignancies in which genomic abnormalities within the hematopoietic stem cell (HSC) compartment lead to pancytopenia and eventual bone marrow failure or progression to leukemia. The most common karyotypic abnormality in MDS is the interstitial deletion of chromosome 5q where a commonly deleted region (CDR) has been identified. Two microRNAs (miRNA) located within the CDR have been shown to be expressed at lower levels in del(5q) MDS compared to diploid MDS. Here I describe investigations of the functional consequence of loss of these two miRNAs, miR-143 and miR-145, on hematopoietic stem and progenitor cells. Loss of miR-143/145 in mice resulted in a decrease in hematopoietic stem cells and myeloid progenitors. I also identified a direct link between the loss of miR-143/145 and subsequent activation of both the canonical and non-canonical transforming growth factor beta (TGFβ) signaling pathways, mediated in part via the adaptor protein, Disabled-2 (DAB2). Analysis of del(5q) MDS patient bone marrow revealed an enriched TGFβ-signature compared to healthy controls and we show that TGFβ signaling is activated upon loss of miR-145 or enforced expression of its target, DAB2. Subsequent studies focused on the function of DAB2 within the hematopoietic system. Overexpression of DAB2 in mouse bone marrow resulted in a significant decrease in hematopoietic stem cell frequency, self-renewal, and colony forming activity. In competitive transplants, vector-transduced bone marrow cells were able to outcompete DAB2-overexpressing marrow in both primary transplants as well as in secondary limiting dilution assays. However, a subset of mice with enforced DAB2 expression alone developed a transplantable acute myeloid leukemia. In conclusion, our data suggest a role for miR-145 haploinsufficiency in the inappropriate activation of TGFβ signaling through derepression of DAB2 which leads to abnormal HSC function in del(5q) MDS.

description: Well-posedness for the initial value problem for a self-gravitating elastic body with free boundary in Newtonian gravity is proved. In the material frame, the Euler-Lagrange equation becomes, assuming suitable constitutive properties for the elastic material, a fully non-linear elliptic-hyperbolic system with boundary conditions of Neumann type. For systems of this type, the initial data must satisfy compatibility conditions in order to achieve regular solutions. Given a relaxed reference configuration and a sufficiently small Newton's constant, a neigborhood of initial data satisfying the compatibility conditions is constructed.

description: We present a new, fully analytical point scattering model which can be applied to arbitrary anisotropic magneto-electric dipole scatterers, including split ring resonators (SRRs), chiral and anisotropic plasmonic scatterers. We have taken proper account of reciprocity and radiation damping for electric and magnetic scatterers with any general polarizability tensor. Specifically, we show how reciprocity and energy balance puts constraints on the electrodynamic responses arbitrary scatterers can have to light. Our theory sheds new light on the magnitude of cross sections for scattering and extinction, and for instance on the emergence of structural chirality in the optical response of geometrically non-chiral scatterers like SRRs. We apply the model to SRRs and discuss how to extract individual components of the polarizability matrix and extinction cross sections. Finally, we show that our model describes well the extinction of stereo-dimers of split rings, while providing new insights in the underlying coupling mechanisms.

description: The neutron-rich N=50 isotones 82Ge and 84Se were investigated using intermediate-energy Coulomb excitation on a 197Au target and inelastic scattering on 9Be. As typical for intermediate-energy Coulomb excitation with projectile energies exceeding 70 MeV/nucleon, only the first 2^+ states were excited in 82Ge and 84Se. However, in the inelastic scattering on a 9Be target, a strong population of the first 4^+ state was observed for 84Se, while there is no indication of a similarly strong excitation of the corresponding state in the neighboring even-even isotone 82Ge. The results are discussed in the framework of systematics and shell-model calculations using three different effective interactions.

Functional genomic analysis of novel microdeletions and microduplications associated with intellectual disability
Creators: name: Badduke, Chansonette
Publisher: name: University of British Columbia
Year: 2016

description: Intellectual disability (ID) is a diagnosis given to persons who have life-long cognitive and adaptive impairments that begin early in life. ID affects about 1-3% of the population. Extremely small chromosome losses and gains, called microdeletions and microduplications respectively (or collectively Copy Number Variants, CNVs), are the cause of ID in ~15% of cases and their identification has helped to pinpoint genomic regions that contain ID-genes. The objective of my PhD research was to search for ID candidate genes in subjects with ID, focusing on the functional genomic analysis of genes from CNVs and in the rest of the genome. I studied individuals with unique de novo pathogenic CNVs at chromosomal position 2p15-16.1 or with familial CNVs at chromosomal position 1q21.1. I used a multi-faceted approach that included the study of candidate genes’ 1) expression, 2) sequence variants, 3) knock down consequence in C. elegans and 4) imprinting potential. My results showed that the best candidate genes from the 2p15-16.1 CNV are XPO1, USP34 and REL because their expression is reduced in individuals with deletions. In case of the 1q21.1 CNV, I identified two candidate genes (CHD1L and PRKAB2) from the CNV that had altered expression and cellular function. I also identified a pathogenic sequence change in ATF6 in individuals with a familial 1q21.1 duplication. ATF6 is located outside the 1q21.1 CNV and is part of the Endoplasmic Reticulum (ER) stress response pathway which may contribute to the phenotypic variability in this family. Finally, I identified 3 CNVs in children with ID that overlap putative imprinted regions. The results of my study therefore led to the identification of genes which could contribute to ID as their function is altered in patients with the CNV or their characteristics suggest that they can be sensitive to copy number changes. This work contributes to an improved understanding of how CNVs and additional genetic changes in the rest of the genome can lead to ID.

Intensive care units
Continuum of care

description: Rationale: Intensive care unit (ICU) patients who receive mechanical ventilation are at high risk for early rehospitalization. Given their medical complexity, a lack of continuity of care may adversely affect outcomes during rehospitalization.

Objective: To determine whether outcomes differ for patients who are rehospitalized at a different hospital versus the hospital of the index ICU stay.

Methods: Retrospective cohort study of mechanically ventilated ICU patients rehospitalized within 30 days in New York State hospitals from 2008-2013.

Measurements: Frequency of rehospitalization at a different hospital; mortality, length of stay and costs during rehospitalization.

Main Results: Of 26,947 mechanically ventilated ICU patients rehospitalized within 30 days of discharge, 8,443 (31.3%) were rehospitalized at a different hospital than that of the index ICU stay. For patients at a different hospital, 13.7% died during rehospitalization versus 11.1% at the index hospital (adjusted rate ratio (aRR) 1.11 [1.03 -1.20], p=0.009). Patients who died at a different hospital had shorter length of stay (aRR 0.80 [0.70-0.92], p=0.001) and decreased costs (adjusted mean difference (aMD) -$9,632.73 [-$16,387.60 to -$-2,877.88], p=0.005), while survivors of rehospitalization at a different hospital had a modest increase in length of stay (aRR 1.06 [1.01-1.11], p=0.009) and increased costs of care (aMD $1,665.34 [$602.12 to $2,728.56], p=0.002).

Conclusions: Almost one-third of mechanically ventilated critically ill patients were rehospitalized at a different hospital than that of the index ICU stay. This care discontinuity was associated with increased mortality. Further investigation should aim to elucidate reasons for differing patterns of care on rehospitalization and strengthen the causal relationship between care discontinuity and subsequent harm.

description: Este artigo tem como tema a história e o significado político e religioso da construção do símbolo e do mito em torno de D. Nuno Álvares Pereira em Portugal nos séculos XIX e XX. Essa percepção é feita, por um lado, através de narrativas literárias e históricas e do seu processo de panteonização; por outro lado, revelando o movimento das associações Nuno Álvares, com destaque para a Cruzada Nacional D. Nuno Álvares Pereira e toda a dinâmica promotora do seu culto religioso (Festa do Santo Condestável) e do culto cívico (Festa da Pátria), com peregrinações e romagens ao Mosteiro da Batalha e ao Campo de Aljubarrota, sem esquecer a liturgia celebrativa dos centenários históricos. Concluiu-se que o recurso simbólico a Nuno Álvares foi um importante factor de unificação dos vários nacionalismos portugueses, evocando-se a partir de 1909 o exemplo patriótico francês de Joana d’Arc.

description: Hypersaline brines are of growing environmental importance but are technologically under-served by today’s desalination methods. Temperature swing solvent extraction (TSSE) is a radically different desalination technology that is membrane-less and not based on evaporative phase change. TSSE utilizes low-temperature heat and a low-polarity solvent with temperature-dependent water solubility for the selective extraction of water over salt from saline feeds. This study demonstrates TSSE desalination of high-salinity brines simulated by NaCl solutions with three amine solvents: diisopropylamine (DIPA), N-ethylcyclohexylamine (ECHA), and N,N-dimethylcyclohexylamine (DMCHA). We show that TSSE can desalinate brines with salinities as high as ≈234000 ppm total dissolved solids (i.e., 4.0 M NaCl) and achieve salt removals up to 98.4%. Among the solvents, DIPA exhibited the highest water extraction efficiency whereas ECHA and DMCHA produced water with the lowest salt content and solvent residue content, respectively. Lastly, a high water recovery of >50% was demonstrated for TSSE desalination of 1.5 M NaCl brine using DIPA in semibatch experiments with multiple extraction cycles. This study underscores the unique capabilities of TSSE for the desalination of hypersaline brines.
Design and characterisation of an improved spinal canal occlusion transducer
Creators: name: Scicchitano, Bartholomew
Publisher: name: University of British Columbia
Year: 2016

description: The spinal canal occlusion transducer (SCOT) is a sensor used to detect changes in geometry of the cervical spinal canal. A constant current field is created in saline filling the SCOT casing. Radial compression of the SCOT casing results in a change in cross sectional area and an increased resistance to current flow. Sensing elements along the SCOT are used to detect the change in potential difference along the length of the probe and quantify the change in area of the SCOT casing. Shortfalls of the existing SCOT iteration were identified for improvement. These included long term durability and stability of the signal. A new design for the SCOT probe was sought with the aim of addressing these shortfalls. Six prototype SCOT probes were designed, manufactured and tested. Prototypes considered sensing elements, the casing materials used, input signal conditions and the method used to construct the SCOT probe. Signal to noise ratio and stability of signal were used to compare the prototypes against the original SCOT. The design chosen consisted of a heat shrink casing, 3.97 mm diameter SS ball bearings for ground and excitation elements, and 3.18 mm diameter SS ball bearings for sensing elements. Electrical connections were soldered. A sinusoidal input with frequency of 3 kHz and peak to peak amplitude of 1.5 V was used. The minimum measurable total canal area was 107.6 ± 1.2 mm². The signal to noise ratio of the new SCOT was 74.3 dB and the variation of unoccluded SCOT signal was found to be 1.4 ± 2.5 mVRMS compared to 74.4 dB and 2.3 mVRMS for the previous iteration. The new SCOT was used in a flexibility study of cervical spine segments. Specimens were loaded in flexion-extension, left-right lateral bending and axial rotation up to 4 Nm at 2 ˚/s. Mean maximum percent decreases in total canal area were 5.8%, 15.9%, 5.1%, 4.6%, 4.6% and 4.2% for flexion, extension, left axial rotation, right axial rotation, left lateral bending, and right lateral bending, respectively. Only extension consistently demonstrated mean maximum decreases that exceeded the mean error of the SCOT (5.3 ± 1.3 mm²).
Multiquark correlations in light mesons and baryons from holographic QCD

Year: 2011
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: A hadron's multiquark content reflects itself in the quark composition of the interpolator with which it has maximal overlap. The AdS/CFT dictionary translates the anomalous dimension of this interpolator into a mass correction for the corresponding dual mode. Hence such bulk-mass corrections can carry holographic information on multiquark correlations. Two prominent examples are studied by implementing this robust and universal mechanism into AdS/QCD gravity duals. In the baryon sector bulk-mass corrections are used to describe systematic good (i.e. maximally attractive) diquark effects. The baryon sizes are predicted to decrease with increasing good-diquark content, and the masses of all 48 observed light-quark baryon states are reproduced with unprecedented accuracy. Our approach further provides the first holographic description of a dominant tetraquark component in the lowest-lying scalar mesons. The tetraquark ground state emerges naturally as the lightest scalar nonet whereas higher excitations become heavier than their quark--antiquark counterparts and are thus likely to dissolve into the multiparticle continuum.

Este estigmatizou ideologicamente a literatura e a historiografia e condicionou a leitura do papel dos Padres da Companhia em termos missionários, educativos e científicos. O artigo desenvolve uma análise do processo de construção e recriação deste mito de complot jesuítico e do seu significado.

description: Neste artigo traça-se o percurso singular de um padre jesuíta, Carlos João Rademaker, restaurador em 1858 da Companhia de Jesus em Portugal. Orador reconhecido, viajante infatigável, foi um dos defensores do catolicismo romano saído do I Concílio do Vaticano. Arauto do neocatolicismo de raiz liberal e intransigência romana, viria a marcar indelevelmente a segunda metade do século XIX português.

description: Using the population synthesis binary evolution code StarTrack, we present theoretical rates and delay times of Type Ia supernovae arising from various formation channels. These channels include binaries in which the exploding white dwarf reaches the Chandrasekhar mass limit (DDS, SDS, and helium-rich donor scenario) as well as the sub-Chandrasekhar mass scenario, in which a white dwarf accretes from a helium-rich companion and explodes as a SN Ia before reaching the Chandrasekhar mass limit. We find that using a common envelope parameterization employing energy balance with alpha=1 and lambda=1, the supernova rates per unit mass (born in stars) of sub-Chandrasekhar mass SNe Ia exceed those of all other progenitor channels at epochs t=0.7 - 4 Gyr for a burst of star formation at t=0. Additionally, the delay time distribution of the sub-Chandrasekhar model can be divided in to two distinct evolutionary channels: the `prompt' helium-star channel with delay times < 500 Myr, and the `delayed' double white dwarf channel with delay times > 800 Myr spanning up to a Hubble time. These findings are in agreement with recent observationally-derived delay time distributions which predict that a large number of SNe Ia have delay times < 1 Gyr, with a significant fraction having delay times < 500 Myr. We find that the DDS channel is also able to account for the observed rates of SNe Ia. However, detailed simulations of white dwarf mergers have shown that most of these mergers will not lead to SNe Ia but rather to the formation of a neutron star via accretion-induced collapse. If this is true, our standard population synthesis model predicts that the only progenitor channel which can account for the rates of SNe Ia is the sub-Chandrasekhar mass scenario, and none of the other progenitors considered can fully account for the observed rates.

Probabilistic models for the identification and interpretation of somatic single nucleotide variants in cancer genomes
Creators: name: Roth, Andrew Justin Latham
Publisher: name: University of British Columbia
Year: 2016

description: Somatic single nucleotide variants (SNVs) are mutations resulting from the substitution of a single nucleotide in the genome of cancer cells. Somatic SNVs are numerous in the genomes of most types of cancers. SNVs can contribute to the malignant phenotype of cancer cells, though many SNVs likely have negligible selective value. Because many SNVs are selectively neutral, their presence in a measurable proportion of cells is likely due to drift or genetic hitchhiking. This makes SNVs an appealing class of genomic aberrations to use as markers of clonal populations and ultimately tumour evolution. Advances in sequencing technology, in particular the development of high throughput sequencing (HTS) technologies, have made it possible to systematically profile SNVs in tumour genomes. We introduce three probabilistic models to solve analytical problems raised by experimental designs that leverage HTS to study cancer biology. The first experimental design we address is paired sequencing of normal and tumour tissue samples to identify somatic SNVs. We develop a probabilistic model to jointly analyse data from both samples, and reduce the number of false positive somatic SNV predictions. The second experimental design we address is the deep sequencing of SNVs to quantify the cellular prevalence of clones harbouring the SNVs. The key challenge we resolve is that allele abundance measured by HTS is not equivalent to cellular prevalence due to the confounding issues of mutational genotype, normal cell contamination and technical noise. We develop a probabilistic model which solves these problems while simultaneously inferring the number of clonal populations in the tissue. The final experimental design we consider is single cell sequencing. Single cell sequencing provides a direct means to measure the genotypes of clonal populations. However, sequence data from a single cell is inherently noisy which confounds accurate measurement of genotypes. To overcome this problem we develop a model to aggregate cells by clonal population in order to pool statistical strength and reduce error. The model jointly infers the assignment of cells to clonal populations, the genotype of the clonal populations, and the number of populations present.

description: As part of a larger hidden collections initiative, Columbia University Libraries initiated plans in 2018 to digitize their unique audiovisual holdings over seven years. In order to meet an ambitious target within a limited timeframe, staff across divisions and departments had to collaboratively develop shared workflows and efficiencies to maximize output while ensuring a high level of quality. Due to the unique challenges of working with audio and video collections, this collaborative effort was truly unprecedented in the history of Columbia Libraries. This project represented an excellent opportunity to test new functionalities of our locally developed digital asset management system Hyacinth and find robust methods to improve digital curation and preservation using tools like Archivematica digital preservation system. The scope of the project required that we develop efficiencies in our cataloging and metadata enhancement workflows including task automation in OpenRefine, sync metadata between systems including our Voyager ILS and Hyacinth, and plan for new initiatives such as the implementation of a rights management module and integration of crosswalks to ArchivesSpace. One additional outcome of the project’s first year is a deeper analysis of project statistics and workflows using project management methods to inform the future development and planning of the project for years 2-7. This presentation will examine the development of these shared workflows across curatorial, preservation, metadata, and digital technology units, challenges overcome, and lessons learned.
O protestantismo em Portugal (séculos XIX e XX): linhas de força da sua história e historiografia
Creators: name: Santos, Luís Aguiar
Publisher: name: Lusitania Sacra
Year: 2000

description: A marginalidade do protestantismo em Portugal não deve atribuir-se à sua repressão por uma sociedade supostamente autoritária e clerical. Pelo contrário, o protestantismo sofreu a concorrência de uma Igreja hegemónica já instalada e de sistemas de crença seculares alternativos à mensagem cristã, enquanto ao longo dos séculos XIX e XX se assistiu a uma lenta evolução de uma tolerância “de facto” a uma tolerância “de jure”. As várias denominações protestantes são caracterizadas e classificadas de acordo com a sua dinâmica interna e respectiva atitude perante a sociedade envolvente. O texto encerra com a definição e problematização do protestantismo enquanto campo de estudo consistente.

description: 3G, processor of 2G services, is a family of standards for mobile telecommunications defined by the International Telecommunication Union [1]. 3G services include wide-area wireless voice telephone, video calls, and wireless data, all in a mobile environment. It allows simultaneous use of speech and data services and higher data rates.3G is defined to facilitate growth, increased bandwidth and support more diverse applications. The focus of this study is to examine the factors affecting the adoption of 3G services among Indian people. The study adopts the revised Technology Acceptance Model by adding five antecedents-perceived risks, cost of adoption, perceived service quality, subjective norms, and perceived lack of knowledge. Data have collected from more than 400 school/college/Institution students & employees of various Government/Private sectors using interviews & various convenience sampling procedures and analyzed using MS excel and MATLAB. Result shows that perceived usefulness has the most significant influence on attitude towards using 3G services, which is consistent with prior studies. Of the five antecedents, perceived risk and cost of adoption are found to be significantly influencing attitude towards use. The outcome of this study would be beneficial to private and public telecommunication organizations, various service providers, business community, banking services and people of India. Research findings and suggestions for future research are also discussed.
