Anaphoric expressions, such as pronouns and referential descriptions, are situated with respect to the linguistic context of prior turns, as well as, the immediate visual environment. However, a speaker's referential descriptions do not always uniquely identify the referent, leading to ambiguities in need of resolution through subsequent clarificational exchanges. Thus, effective Ambiguity Detection and Coreference Resolution are key to task success in Conversational AI. In this paper, we present models for these two tasks as part of the SIMMC 2.0 Challenge (Kottur et al. 2021). Specifically, we use TOD-BERT and LXMERT based models, compare them to a number of baselines and provide ablation experiments. Our results show that (1) language models are able to exploit correlations in the data to detect ambiguity; and (2) unimodal coreference resolution models can avoid the need for a vision component, through the use of smart object representations., Accepted to AAAI 2022 DSTC10 Workshop

Introdu����o: O handover / Handoff consiste no processo de transfer��ncia da responsabilidade ou seja, a transmiss��o de informa����o especifica acerca de um doente, de um prestador de cuidados para outro ou dos prestadores de cuidados para o doente e fam��lia, de forma a permitir uma continuidade de cuidados e com vista a seguran��a do doente. O servi��o de urg��ncia (SU), como recetor do doente cr��tico, tem particularidades que dificultam uma comunica����o eficaz pelo que, torna-se fundamental a exist��ncia de um handover minucioso, de forma a melhorar a qualidade e a seguran��a do doente dentro do sistema de sa��de. Deste modo opt��mos por realizar uma revis��o integrativa de literatura. Objetivos: Identificar os fatores promotores e inibidores do handover do doente critico no SU, conhecer o conte��do a transmitir no handover do doente critico no SU e identificar ferramentas de apoio ao handover. Material e m��todos: Realizou-se uma revis��o integrativa, seguindo a metodologia proposta por Joanna Briggs Institute, atrav��s da conjuga����o de termos MesH recorrendo �� base de dados EBSCO host ��� Research Databases, nas bases de dados CINAHL complete, MEDLINE complete, Cochrane Central Register Of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, nos idiomas portugu��s e ingl��s e na janela temporal de 2010 a 2020. Resultados: A amostra foi constitu��da por sete estudos em que se identificaram cinco categorias, nomeadamente, fatores promotores e fatores inibidores do handover, conte��do do handover, ferramentas de handover, e recomenda����es para uma melhoria do handover. Conclus��es: A pesquisa realizada revelou a import��ncia do handover no servi��o de urg��ncia. Uma aposta na sua qualidade promove uma transi����o de cuidados segura. O uso de ferramentas padronizadas, uma linguagem estruturada e equipas especializadas aumentam a qualidade dos cuidados e os resultados dos doentes, com menor morbilidade. �� fundamental investir na forma����o interdisciplinar e interinstitucional nesta ��rea pois, o handover adequado traz benef��cios para os doentes, profissionais e sistema de sa��de., Cadernos de Sa��de, v. 13 n. 2 (2021)

The asteroseismic modelling of solar-like stars has proved to be valuable in constraining dark matter. In this work we study for the first time the influence of asymmetric dark matter (ADM) in the evolution of a subgiant star (KIC 8228742) by direct comparison with observational data. Both spectroscopic and seismic data are analysed with a new approach to the stellar calibration method, in which DM properties can also be considered as free inputs. In another phase of this study, a calibrated standard stellar model (without DM) is used as the benchmark for DM models. We find that the latter models consistently outperform the former for $10^{-40} \leq ��_\mathrm{SD} < 10^{-38}$ cm$^2$, hinting that the presence of ADM in stars of this type does not go against observations. Moreover, we show that stellar seismology allows us to suggest exclusion limits that complement the constraints set by direct detection experiments. Different seismic observables are proposed to study DM properties and $����_\ell$ is found to be the most reliable, having the potential to build future DM exclusion diagrams. This new methodology can be a powerful tool in the analysis of the data coming from the next generation of asteroseismic missions., 10 pages, 8 figures, 1 table

Challenges around collecting and processing quality data have hampered progress in data-driven dialogue models. Previous approaches are moving away from costly, resource-intensive lab settings, where collection is slow but where the data is deemed of high quality. The advent of crowd-sourcing platforms, such as Amazon Mechanical Turk, has provided researchers with an alternative cost-effective and rapid way to collect data. However, the collection of fluid, natural spoken or textual interaction can be challenging, particularly between two crowd-sourced workers. In this study, we compare the performance of dialogue models for the same interaction task but collected in two different settings: in the lab vs. crowd-sourced. We find that fewer lab dialogues are needed to reach similar accuracy, less than half the amount of lab data as crowd-sourced data. We discuss the advantages and disadvantages of each data collection method., Accepted at Human in the Loop Dialogue Systems Workshop @NeurIPS 2020

Introdu??o: exerc?cio f?sico e artes marciais podem exercer influ?ncia no desempenho cognitivo de idosos, atuando como ferramentas importantes de preven??o do desenvolvimento de quadros de decl?nio cognitivo e incrementar estrat?gias de interven??o. As artes marciais, especialmente o Karate-D?, nosso objeto de estudo, s?o consideradas formas de exerc?cio completas, que al?m de trazerem benef?cios ? sa?de f?sica, contribuem para estimular habilidades motoras e cognitivas, melhora da qualidade de vida e de aspectos emocionais de seus praticantes. Objetivo: Verificar o desempenho das fun??es cognitivas e capacidade de reserva cognitiva em idosos praticantes de Karate-D? de longa data. M?todo: realizou-se um estudo transversal e comparativo com 99 idosos divididos em tr?s grupos: Grupo Karate-D? de longa data (n = 37), Grupo de Sedent?rios (n = 41) e Grupo de Atividades Sociais (n = 21). Os idosos responderam a um question?rio sociodemogr?fico, a uma bateria de testes cognitivos (avalia??o de orienta??o t?mporo-espacial, registro, aten??o, c?lculo, evoca??o, linguagem e fun??es executivas) e a escalas de queixas cognitivas subjetivas e de humor (ansiedade e depress?o). O Grupo de Sedent?rios n?o realizava nenhuma atividade f?sica e o Grupo de Atividade Social participava de atividades sociais variadas, mas n?o exerc?cio f?sico. A an?lise dos dados foi realizada com estat?sticas descritivas e de infer?ncias. A distribui??o dos dados foi verificada atrav?s do teste de Kolmogorov-Smirnov. Diferen?as entre os grupos foram investigadas pelo teste Kruskal-Wallis e Teste U de Mann-Whitney. Resultados: na compara??o entre os grupos, o Grupo de Sedent?rios obteve menos escores no Question?rio de Reserva Cognitiva em compara??o ao Grupo de Atividades Sociais (p = 0,012) e Grupo Karate-D? de longa data (p ? 0,001), sendo que este dois obtiveram pontua??es semelhantes (p = 0,104) no Question?rio de Reserva Cognitiva. O Grupo de Sedent?rios obteve maior pontua??o na subescala Motiva??o da GDS-15 quando comparado com o Grupo de Atividades Sociais (p = 0,016). Conclus?o: a pr?tica de Karate-D? de longa data parece trazer benef?cios quanto ? capacidade de reserva cognitiva a idosos praticantes saud?veis. Ao mesmo tempo, evidenciou-se que atividades sociais parecem incrementar a capacidade de reserva cognitiva e est?o relacionadas ? redu??o de sintomas depressivos. Introduction: physical exercise and martial arts can influence the cognitive performance of the old people, acting as important tools to prevent cognitive impairments and to increase intervention strategies. Martial arts, especially Karate-D?, are considered wide-ranging types of exercise, which in addition to bringing benefits to physical health, contribute to stimulate motor and cognitive skills, improve the quality of life and emotional aspects of their practitioners. Objective: to verify the performance of cognitive functions and cognitive reserve capacity in elderly people practicing Karate-D? in long term. Methods: a cross-sectional and comparative study was carried out with 99 elderly people divided into three groups: Long-time Karate-D? Group (n=37), Sedentary Group (n=41) and Social Activities Group (n=21). The subjects respond to a sociodemographic questionnaire, a battery of cognitive tests (evaluation of time-space orientation, recording, attention, calculation, evocation, language and executive functions) and scales of subjective cognitive complaints and humoral (anxiety and depression). The Sedentary Group did not perform any physical activity and the Social Activities Group participated in varied social activities, but not physical exercise. Data analysis was performed with descriptive and inferential statistics. Data distribution was verified using the Kolmogorov-Smirnov test. Differences between groups were investigated by the Kruskal-Wallis test and Mann-Whitney U test. Results: in the comparison between groups, the Sedentary Group individuals scored lower on the Cognitive Reserve Questionnaire than in the Social Activities Group (p=0.012) and the Long-time Karate-D? Group (p?0.001). obtained similar scores (p=0.104) in the Cognitive Reserve Questionnaire. The Sedentary Group scored higher on the motivation subscale of GDS-15 when compared to the Social Activities Group (p=0.016). Conclusions: Karate-D? practice seems to bring in long term benefits to cognitive reserve capacity to healthy seniors. At the same time, it was evidenced that social activities seem to increase the capacity of cognitive reserve and are related to the reduction of depressive symptoms.

In this work, we study the impact of asymmetric dark matter (ADM) on low-mass main-sequence stars in the Milky Way's nuclear star cluster, where the dark matter (DM) density is expected to be orders of magnitude above what is found near the Sun (${��}_{\mathrm{DM}}\gtrsim {10}^{3}\ \mathrm{GeV}\ {\mathrm{cm}}^{-3}$). Using a modified stellar evolution code and considering a DM particle ($m_�� = 4 \text{ GeV}$) with a spin-dependent interaction cross section close to the limits allowed by direct detection, we found that the interactions of ADM with baryons in the star's core can have two separate effects on the evolution of these stars: a decrease in the hydrogen burning rate, extending the duration of the main-sequence of stars with $M ~ 1M_{\odot}$ by a few Gyr; the suppression of the onset of convection in the core of stars with $M \lesssim 1.5M_{\odot}$ and consequent quench of supply for the nuclear reactions. If we consider $��_{\text{DM}} > 10^3 \ \text{GeV cm}^{-3}$ (corresponding to the inner 5 pc of the Milky Way), stars lighter than the Sun will have a main-sequence life span comparable to the current age of the universe. Stars heavier than two solar masses are not sensitive to the DM particles considered here.

Mestrado em Engenharia do Software na Escola Superior de Tecnologia e Gest?o do Instituto Polit?cnico de Viana do Castelo O Cortejo das festas em honra de N. Sr?. D?Agonia, que se realiza anualmente na cidade de Viana do Castelo, ? um dos pontos altos da romaria que re?ne v?rias centenas de figurantes, num desfile pelas ruas da cidade, sendo que este evento atrai tamb?m milhares de espetadores. Devido ? sua enorme dimens?o apresenta algumas dificuldades a n?vel de organiza??o. A falta de coes?o do Cortejo durante o seu decurso ? um dos problemas encontrados que d? origem a enormes espa?os vazios entre quadros, o que e desprestigia o desfile. Neste trabalho pretende-se estudar o problema dos espa?os vazios que surgem durante o Cortejo, propor uma solu??o baseada em tecnologias de custo reduzido e avaliar o desempenho dessa solu??o junto dos seus potenciais utilizadores. Deste modo, iniciou-se um processo de recolha de informa??o atrav?s da observa??o do Cortejo, de uma entrevista ? organiza??o e de um inqu?rito a colaboradores e outro a motoristas. Este processo teve por objetivo fazer um levantamento de requisitos, de forma a identificar as principais necessidades para que seja poss?vel auxiliar a organiza??o do Cortejo. Com base na recolha efetuada, prop?e-se uma solu??o que utiliza smartphones para se interligarem atrav?s de uma aplica??o m?vel e, tamb?m, uma aplica??o web de gest?o, de forma a monitorizar o Cortejo e ajudar na supress?o dos espa?os vazios. Por fim, implementou-se um prot?tipo tendo em vista a sua valida??o pelos potenciais utilizadores. Assim, para efetuar a valida??o do sistema, simulou-se um micro Cortejo com o objetivo de comprovar a funcionalidade e realizaram-se testes de Usabilidade e de Experi?ncia do Utilizador com os respetivos participantes. A aplica??o cumpre os objetivos que foram propostos, concluindo assim que os resultados s?o positivos. Contudo, existem alguns aspetos que podem ser melhorados quer a n?vel de interface, quer a n?vel da precis?o da localiza??o. The parade of ?Festas in honor of Nossa Senhora d?Agonia?, which is celebrated every year in the city of Viana do Castelo, it is one of the highlights of the traditional festival, that gathers hundreds of people in one giant parade throughout the city streets. This event also draws the attention of thousands of spectators. Due to its big dimension, it presents some difficulties regarding its organization. The lack of cohesion of the parade during its course is one of the issues observed that originates several and large empty spaces, which end up to discredit the parade. In this work, the main goal is to study the issue related with the Parade?s organization/planning, by proposing a solution based on low-cost technologies and evaluating the performance of this solution with its users. Firstly, there was a process of collecting information by observing the Parade, followed by Parade?s staff interviews and collaborators and drivers? inquiries. This process was used to find and collect the requirements needed in order to help to monitor the organization/planning of the Parade. Based on the previous data gathering, it follows a proposal that uses smartphones to interconnect and, also, a management web application, in order to monitor the Parade and to assist in the control of empty spaces. Lastly, a prototype was implemented with the hope of approval from its potential users. Thus, in order to validate and test the system, a micro-Parade was simulated to prove its functionality and, consequently, there were used the Usability and User?s Experience tests with the participants. The application fulfils the objectives that were, initially, proposed, and we can conclude that the results were positive. However, there are some aspects that can be improved in the future, regarding the interface and the precision of location future. Palavras Chave

The use of natural products as an alternative for treatment and prevention of diseases has been increasing daily. Lippia alba is a shrub widely distributed throughout Brazil and its aqueous extracts, as infusion and decoction made from its leaves, are currently being used in popular medicine. Thus, the objective of the study was to do a phytochemical screening of these solutions as well as evaluate in vitro antimicrobial activity of these solutions in the reduction of: Streptococcus mutans (ATCC 25175), Streptococcus mitis (ATCC 49456), Staphylococcus aureus (ATCC 12600) and Lactobacillus casei (ATCC 27216). The negative and positive controls were respectively, BHI and Chlorhexidine. Statistical analysis was performed using the Mann-Whitney and Kruskal-Wallis test with Bonferroni's penalization, showing significant difference between the products tested (p

Neuromuscular disorders encompass a wide category of illnesses with a significant burden on the patient, family, and society. Telehome monitoring presents an alternative for closer follow-up, by ensuring timely transmission of data and prompting medical support before deterioration occurs. We used telehome monitoring devices for amyotrophic lateral sclerosis patients with respiratory failure in a clinic. This instrument directly acts as a digital recorder of parameters received from an external instrument, such as the bi-level ventilator, and contains an internal modem for direct connection to the Internet, thereby allowing bidirectional flexibility in collecting data and parameter changes whenever needed. The use and acceptance of the system was investigated with patients and all therapists involved. The instrument was found to be user-friendly and effective by the researchers, being practical for both patients and therapists. Therefore, it can be integrated into a routine home care application based on a large respiratory rehabilitation center. The device was extensively tested, and in an ongoing randomized controlled study it is being investigated whether this management strategy is able to hasten the ventilator adaptation process and to diminish the overall utilization of health services, with concurrent economic viability. We conclude that home telemonitoring represents a positive contribution to the management of chronic patients and raised awareness of it should be considered in a near future. This portable telemonitoring device provides an opportune approach to better understand and recognize a ventilatory pattern through long-term ventilation monitoring in the home environment.

We used a consistent and robust solar model to obtain upper limits placed by neutrino telescopes, such as Ice- Cube and Super-Kamiokande, on the Dark Matter-nucleon scattering cross-section, for a general model of Dark Matter with a velocity dependent (p-wave) thermally averaged cross-section. In this picture, the Boltzmann equation for the Dark Matter abundance is numerically solved satisfying the Dark Matter density measured from the Cosmic Microwave Background (CMB). We show that for lower cross-sections and higher masses, the Dark Matter annihilation rate drops sharply, resulting in upper bounds on the scattering cross-section one order of magnitude above those derived from a velocity independent (s-wave) annihilation cross-section. Our results show that upper limits on the scattering cross-section obtained from Dark Matter annihilating in the Sun are sensible to the uncertainty in current standard solar models, fluctuating a maximum of 20 % depending on the annihilation channel., 9 pages, 5 figures

Conclus?o : O treinamento de Karate-Do estilo Wado-ryu mostrou-se eficaz na estimula??o cognitiva de idosos saud?veis, especialmente em tarefas de aten??o, mem?ria e fun??es executivas. Introduction : Physical activity and martial arts have a major influence on cognitive performance of elderly, and can be important tools for preventing the development of cognitive decline and improve intervention strategies. Martial arts, especially Karate-Do, our object of study, are considered forms of complete exercise, which besides bringing benefits to physical health, contribute to stimulate motor and cognitive skills, improved quality of life and emotional aspects of their practitioners. Objective : to determine the effectiveness of a Karate-Do training, Wado-ryu style, on cognition in healthy elderly. Methods : A randomized controlled clinical trial was conducted with 33 elderly divided into two groups: Karate group (n = 16) and Control group (n = 17). In the pre and post-intervention phases, the elderly answered a sociodemographic questionnaire, a battery of neuropsychological tests (evaluation of attention, memory, language, perception, visoconstruction abilities and executive functions), subjective cognitive complaints and mood scales (anxiety and depression). Intervention with Karate-Do was conducted twice a week, lasting 60 minutes each session, for 12 weeks. The exercises consisted of kihon, kata and kumite typical of Karate-Do. Control group did not perform any physical activity or cognitive stimulation during the intervention period. Data analysis was conducted using descriptive and inferences statistics. A comparison of performance neuropsychological tests and subjective complaints scales, within and between-groups in the pre- and post-intervention, was performed using the Mann-Whitney test and Wilcoxon test. Results : the groups showed no statistically significant differences in the sociodemographic and clinical data in the pre-intervention phase. In intra-group comparison, at the end of the intervention, Karate Group achieved better performance in visual memory (Mpre: 11,78; sdpre: 6,12 / Mpost: 14,38; sdpost: 5,35 / p: 0,041), alternating attention (Mpre: 146,98; sdpre: 92,74 / Mpost: 121,39; sdpost: 70,71; p: 0,017), episodic verbal memory (Mpre: 43,88; sdpre: 7,74 / Mpost: 49,06; sdpost: 8,06; p: ?0,001), executive functions tasks (Mpre: 21,88; sdpre: 15,07 / Mpost: 31,88; sdpost: 14,91; p: 0,024) and reduction of subjective memory complaints by relatives (Mpre: 24,63; sdpre: 3,12 / Mpost: 19,69; sdpost: 5,61; p: 0,003). Control Group showed no significant differences in cognitive performance between pre- and post-intervention.

As Redes Socias tem sido recentemente identificadas como ferramentas chave nos atos de facilitar ou restringir a colaboracao, principalmente no que diz respeito a sua utilizacao na Educacao, tendo em vista principalmente, conceitos ligados a interacao e a formacao de grupos em tais ambientes. Os processos educacionais sempre dependeram muito da existencia de grupos, sejam os grandes, como a comunidade, ou os pequenos, como nas atividades em sala de aula e a maior utilizacao das Redes Sociais em contextos educativos vem nos provar isso, visto que houve um crescimento na utilizacao da aprendizagem colaborativa, onde fatores socio-afetivos aplicados aos grupos de aprendizagem colaborativos apoiados por computador tem um importante papel. O presente trabalho vem demonstrar um novo olhar sobre a era da interatividade e seus efeitos na vida social dos individuos, os quais estao cada vez mais interligados na rede mundial de computadores. Nesse contexto, com a utilizacao e aplicacao do questionario caracterologico Roger Verdier, as afinidades sociais podem ser mais bem observadas, dando espaco a criacao de comunidades virtuais onde seus participantes possuam caracteristicas socioculturais proximas (afins), facilitando a sua interacao no ambiente virtual de trabalho.

Esta disserta??o analisa a concep??o teol?gica dos crist?os leigos na linguagem e doutrina da Igreja Cat?lica. Parte da eclesiologia como o lugar teol?gico da exist?ncia constante do laicato na tradi??o eclesial, analisando os fatores de natureza hist?rica e de natureza teol?gica segundo os quais se evidenciam nuances na forma e no grau de envolvimentos dos membros do laicato na miss?o da Igreja. A partir dessa perspectiva dial?tica, pr?pria da natureza da eclesiologia por causa da dimens?o invis?vel e vis?vel da Igreja como ?nica realidade na hist?ria, foi estudado o fen?meno da A??o Cat?lica para compreender o horizonte pastoral e teol?gico dos padres conciliares no Conc?lio Vaticano II. Dadas ?s devidas contextualiza??es, hist?ricas e teol?gicas, do evento conciliar, desenvolve-se a interpreta??o do IV cap?tulo da Constitui??o Dogm?tica Lumen Gentium sobre a Igreja, no qual ? explicitado o n?cleo teol?gico-dogm?tico sobre o laicato da Igreja Cat?lica. Uma vez identificado esse n?cleo teol?gico foram analisados os textos conclusivos das Confer?ncias Gerais do Episcopado da Am?rica Latina CELAM, averiguando o seu respectivo desenvolvimento teol?gico, onde se constata a recep??o integral, mas gradual da concep??o dos crist?os leigos emitida pelo Conc?lio Vaticano II. Essa gradualidade significa que as confer?ncias acentuam alguns aspectos teol?gicos sobre os leigos, em conson?ncia com os desafios da miss?o evangelizadora da Igreja na realidade da Am?rica Latina. No conjunto da disserta??o evidencia-se a voca??o secular dos leigos como um dos avan?os do Conc?lio Vaticano II e o respectivo empenho das Confer?ncias do CELAM em efetiv?-la eclesialmente. This dissertation analyses the theological conception of Christian laymen of the Catholic Church language and doctrine. Part of ecclesiology as the theological place of constant existence of laity in the ecclesial tradition, analyzing the historical and theological factors, in which nuances are evidenced in form and degree of involvement of lay members in Church`s mission. From this dialectic perspective, by the nature of ecclesiology because of the invisible and visible dimension of Church as the only reality in history, the phenomenon of the Catholic Action to comprehend the pastoral and theological horizon of council priests in the Council Vatican II was studied. Contextualization properly given, historical and theological of the council event, the interpretation of IV chapter of Dogmatic Constitution Lumen Gentium about the Church was developed, in which is explained the theological dogmatic nucleus about the laity of the Catholic Church. Once this theological nucleus was identified, conclusive texts of General Conferences of the Episcopate of Latin America CELAM, were analyzed, ascertaining its respective theological development, in which it is found the integral perception, but gradual of conception of Christian laymen emitted by Vatican Council II. This graduallity means that the conferences accentuate some theological aspects about laymen, in consonance with the challenges of the evangelizing mission of Church in Latin America`s reality. In the entirety of the dissertation, the secular vocation of the laity can be evidenced as one advance of Vatican Council II and the respective effort of CELAM conferences in effect it ecclesially.

Muitas esp?cies de leguminosas apresentam potencial para recupera??o de ?reas degradadas, uma vez que possuem associa??o com bact?rias fixadoras de nitrog?nio, principalmente as do g?nero Chamaecrista. Contudo, existem poucas informa??es a respeito das esp?cies desse g?nero. E, considerando a import?ncia biol?gica dos campos rupestres, a ecol?gica das leguminosas e a lacuna de conhecimento que se tem sobre as esp?cies da flora na Cadeia do Espinha?o no Planalto de Diamantina, MG, esse estudo teve como objetivo conhecer os aspectos relacionados ? fenologia e germina??o de sementes de Chamaecrista debilis (Vogel) Irwin e Barneby. As observa??es fenol?gicas foram realizadas em ?reas de campos rupestres no campus da Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM), Diamantina-MG. Os testes de germina??o foram conduzidos no Laborat?rio de Sementes da UFVJM. Foram marcados e monitorados 30 indiv?duos da esp?cie, onde avaliou-se quinzenalmente, de abril de 2010 a mar?o de 2011, as seguintes fenofases: caducifolia, brota??o, flora??o e dispers?o. Verificou-se que a brota??o e flora??o, estiveram associadas com a esta??o ?mida enquanto a dispers?o e a queda de folhas com a esta??o seca. Para avaliar a germina??o foi efetuado um teste de germina??o com 12 tratamentos: testemunha, escarifica??o com lixa d??gua n.80, imers?o em ?gua a 100oC por 5, 10, 15 , 30 e 60 segundos e imers?o em ?cido sulf?rico concentrado por 5, 10, 15, 30 e 60 segundos. Foram avaliadas as porcentagens de germina??o das sementes, o ?ndice de velocidade de germina??o e do teor de ?gua das sementes de Chamaecrista debilis. Utilizou-se o delineamento inteiramente casualizado com quatro repeti??es, e as m?dias foram comparadas pelo teste de Scott-Knott, a 5% de probabilidade. Os dados indicaram que a sazonalidade clim?tica da regi?o ? determinadora dos padr?es fenol?gicos em Chamaecrista debilis. Para a germina??o verificou-se que as sementes apresentaram teor de ?gua de 11,71%. Os tratamentos com ?gua a 1000C a 5, 10 e 15 segundos e ?cido sulf?rico a 15 segundos foram os mais eficientes em promover a germina??o. Disserta??o (Mestrado) ?

ABSTRACT The family Leguminosae comprises about 727 genera and 19,325 species, and is well represented in the Espinha?o considered a Biosphere Reserve by UNESCO, the bearer of a high degree of endemic and rare species, which has suffered the loss of habitats by human activity. Many species of legumes have potential for recovery of degraded areas, as they have an association with nitrogen fixing bacteria, especially those of the genus Chamaecrista. However, little information exists about the species of this genus. And considering the biological importance of the stony fields, the leguminous plants and ecological knowledge gap that exists about the species of flora in the Espinha?o of the Diamantina Plateau, Minas Gerais (MG), Brazil, this study aimed to understand the aspects related to phenology and germination seeds of Chamaecrista debilis (Vogel) Irwin and Barneby. The phenological observations were carried out in areas of rocky fields on the campus of University of the Valleys of Jequitinhonha and Mucuri (UFVJM), Diamantina, MG. Germination tests were conducted at the Laboratory of Seeds of UFVJM. Were marked and monitored 30 individuals of the species, which we assessed biweekly from April 2010 to March 2011, the following phenophases: shedding, budding, flowering and seed dispersal. It was found that the budding and flowering, were associated with the wet season while the dispersion and fall of leaves in the dry season. To evaluate the germination, a germination test conducted with 12 treatments: control, scarification with sandpaper n.80, in water at 1000C for 5, 10, 15, 30 and 60 seconds and immersion in concentrated sulfuric acid for 5, 10, 15, 30 and 60 seconds. We evaluated the germination of seeds, the germination speed index and water content of seeds of Chamaecrista debilis. We used a completely randomized design with four replications and means were compared by Scott-Knott test at 5% probability. The data indicated that the climate in the region is the determinant of phenological patterns in Chamaecrista debilis. For germination was found that the seeds had a water content of 11.71%. The treatment with water at 1000C to 5, 10 and 15 seconds and 15/2 sulfuric acid were more effective in promoting germination.

The objective is to present the procedures to make possible to use a test site to compare the acting of different manufacturers' equipments. It begins with a site where its physical and propagation parameters are obtained, always the same for those certain points, to compare the performance of several equipments through reference measures in terms of the data rate efficiency. The site is characterized through 51 measure points. The tools used and developed for the test accomplishment are also described. Such tools are, for example, the coverage prediction software CellPlanner and a software tool, called GetMIB developed to capture, through the SNMP commands, the stored data in MIBs, and a script for tasks automation by the free software AutoiT. The test results presented the Signal-to-Noise-Relation (SNR), the values of BETA (?), which represents the path loss exponent, the Instantaneous and Accumulated Efficiencies of data rate net communication, as well as the correlation between these obtained variables, which have been presented in graphs and tables. The proposed method has proved to be reliable once it has presented suitable results with the performance expectation of the equipment and is in accordance with the environment used in the tests. From the results verified for the tested equipment, its replacement by other equipments of several manufacturers can be conceived, with similar results. From the confrontation of these results it is possible to obtain information on which equipment better adapts to those operation conditions imposed by the site. Este trabalho traz como hip?tese a possibilidade do desenvolvimento de um m?todo capaz de avaliar equipamentos de uma WMAN em termos de cobertura e desempenho, retratado atrav?s de sua efici?ncia, voltada para a tecnologia WiMAX, padr?o IEEE 802.16-2004. O objetivo ? apresentar os procedimentos que possibilitem utilizar um site de testes, para comparar o desempenho de equipamentos de diferentes fabricantes. Parte-se de um site, onde se obtenham os par?metros f?sicos e de propaga??o do mesmo, sempre iguais para aqueles pontos determinados, comparar o desempenho de equipamentos diversos atrav?s de medidas de refer?ncia, em termos da efici?ncia da taxa de dados. O site fica caracterizado atrav?s de 51 pontos de medida. S?o tamb?m descritas as ferramentas utilizadas e desenvolvidas para a realiza??o dos testes, tais como o software de predi??o de cobertura CellPlanner, uma ferramenta de software chamado de GetMIB desenvolvido para capturar, via SNMP, os dados armazenados nas MIBs, e um script atrav?s do sofware livre AutoiT para automatiza??o das tarefas. Os resultados dos testes realizados apresentaram a Rela??o Sinal Ru?do (SNR), os valores de BETA (?), que representa o expoente de perda de percurso, as Efici?ncias Instant?nea e Acumulada da rede de comunica??o de dados, bem como a correla??o entre estas vari?veis obtidas, as quais foram apresentadas de forma gr?fica e tabeladas. O m?todo proposto se mostrou confi?vel uma vez que apresentou resultados condizentes com a expectativa de desempenho do equipamento e em conformidade com o ambiente utilizado nos testes. A partir dos resultados verificados para o equipamento testado, pode-se conceber a sua substitui??o por outros equipamentos de fabricantes diversos, obtendo-se resultados similares. Da confronta??o destes resultados ? poss?vel obter-se informa??es sobre qual equipamento melhor se adapta ?quelas condi??es de opera??o impostas pelo site.
