Teoria das filas: aplicação dos conceitos em uma casa lotérica na cidade de Itumbiara – GO/ Queue theory: application of the concepts in a lottery house in the city of Itumbiara - GO

Buscando amenizar o tempo de espera ou até mesmo eliminar as filas de uma determinada Casa Lotérica, nesse trabalho utilizou os conceitos da Teoria de Filas para compreender os problemas e elaborar possíveis melhorias. A Casa Lotérica realiza vários serviços em seu estabelecimento, havendo um público diversificado. Por meio disso, obteve o seguinte problema de pesquisa: É possível realizar um sistema sem filas nas casas lotéricas? Ou ao menos, diminuí-las significativamente? Até que ponto é viável financeiramente para o gestor da empresa suprir esse requisito de não ter filas nos seus caixas? Para responder essas questões e atingir os objetivos propostos nesse estudo, buscou-se coletar dados e informações importantes referente aos atendimentos prestados, e para isso, utilizou-se como instrumento de coleta de dados a observação. Foram analisados apenas dois caixas (Obedecendo o modelo de filas M/M/S) e a análise das filas foi focada em identificar o número de clientes que chegam no estabelecimento, o tempo de espera dos mesmos na fila, o tempo de atendimento e o tempo final que o cliente passa pelo sistema. Após a realização dos cálculos com os dados coletados na Casa Lotérica, foi concluído que o atendimento é satisfatório, estando com a taxa de utilização excelente e o tempo de espera dentro das leis do consumidor, utilizando apenas 2 funcionários de atendimento normal e 1 de atendimento prioritário, o qual foi desconsiderado na observação

Características familiares y apoyo percibido entre adolescentes brasileños con y sin experiencia de embarazo

En este estudio se investigó cómo los adolescentes con experiencia de embarazo evaluaron el apoyo que recibieron de su familia, en comparación con un grupo de adolescentes que no había pasado por esta experiencia. Participaron 452 adolescentes de ambos sexos, con edades entre 14 y 19 años y nivel socioeconómico bajo. Los resultados señalan que, proporcionalmente, más mujeres (64.2%) que hombres (35.8%) relataron haber tenido experiencia de embarazo, ?2 (2, n = 2617) = 48.32, p < .001. Además, se observó que el grupo con experiencia de embarazo, comparado con el grupo sin experiencia, reveló mayor percepción de seguridad en las relaciones familiares, t (408) = -3.0, p < .01; de respeto mutuo entre los miembros de la familia, t (392) = -2.3, p < .05; y que recibieron apoyo general más fuerte de su familia, t (397) = -1.3, p < .05. Estos resultados son discutidos en este texto

Características familiares e apoio percebido entre adolescentes brasileiros com e sem experiência de gravidez

The present paper aimed to investigate how adolescents with pregnancy experience evaluate received support from their families in comparison with an adolescent group without pregnancy experience. 452 low income adolescents, both sex, aged 14 to 19 years old answered to a questionnaire. The results revealed that more girls (64.2 %) than boys (35.8 %) declared pregnancy experience, ?2 (2, n = 2617) = 48.32, p &lt; .001. Moreover, it was observed that the group with pregnancy experience, in comparison with other group, revealed more perception on the family relationships safety, t (408) = -3.0, p &lt; .01; mutual respect among family members in their homes, t (392) = -2.3, p &lt; .05; and received stronger general support from their family, t (397) = -1,3, p &lt; .05.

The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment

The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourteenth from SDSS overall (making this, Data Release Fourteen or DR14). This release makes public data taken by SDSS-IV in its first two years of operation (July 2014-2016). Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS website (www.sdss.org) has been updated for this release, and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020, and will be followed by SDSS-V.Comment: SDSS-IV collaboration alphabetical author data release paper. DR14 happened on 31st July 2017. 19 pages, 5 figures.

PLANEJAMENTO E PROGRAMAÇÃO LOCAL EM SAÚDE (PPLS): UMA PROPOSTA PARA DESENVOLVIMENTO DE AÇÕES NA ATENÇÃO PRIMÁRIA À SAÚDE

A busca por modelos de atenção com ênfase na promoção da saúde vem proporcionando a diversificação de cenários para novas práticas de ensino nas escolas médicas do Brasil. O objetivo deste artigo foi descrever o uso do planejamento local no desenvolvimento de ações de saúde numa comunidade em Feira de Santana-Bahia. Trata-se de uma atividade desenvolvida pela disciplina "Práticas de Integração, Ensino, Serviço e Comunidade" (PIESC) do curso de medicina da Universidade Estadual de Feira de Santana (UEFS). Para orientar as intervenções a serem realizadas, utilizou-se a Programação e Planejamento Local em Saúde (PPLS) que se constitui num instrumento metodológico voltado para a execução de práticas de promoção de saúde em nível local do Sistema Único de Saúde. Assim, foi construída uma planilha operativa elaborada a partir de agravos à saúde mais frequentes na área de abrangência da Unidade de Saúde da Família (USF) Gabriela II. Inicialmente, foram programadas 12 atividades. Contudo, houve necessidade de reformulação da proposta devido à reavaliação das oficinas, reduzindo o número de atividades propostas para dez. Foram avaliados no presente artigo variantes resultantes da PPLS como reflexo da participação de terceiros nas ações educativas, na habilidade em transpor obstáculos na efetivação das intervenções e interação entre comunidade, USF e alunos. As observações desta experiência de planejamento em saúde reforçam a importância da utilização do PPLS na programação das ações voltadas para o enfrentamento das necessidades de saúde da população

MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal

Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.

Altimetry for the future: Building on 25 years of progress

In 2018 we celebrated 25 years of development of radar altimetry, and the progress achieved by this methodology in the fields of global and coastal oceanography, hydrology, geodesy and cryospheric sciences. Many symbolic major events have celebrated these developments, e.g., in Venice, Italy, the 15th (2006) and 20th (2012) years of progress and more recently, in 2018, in Ponta Delgada, Portugal, 25 Years of Progress in Radar Altimetry. On this latter occasion it was decided to collect contributions of scientists, engineers and managers involved in the worldwide altimetry community to depict the state of altimetry and propose recommendations for the altimetry of the future. This paper summarizes contributions and recommendations that were collected and provides guidance for future mission design, research activities, and sustainable operational radar altimetry data exploitation. Recommendations provided are fundamental for optimizing further scientific and operational advances of oceanographic observations by altimetry, including requirements for spatial and temporal resolution of altimetric measurements, their accuracy and continuity. There are also new challenges and new openings mentioned in the paper that are particularly crucial for observations at higher latitudes, for coastal oceanography, for cryospheric studies and for hydrology. The paper starts with a general introduction followed by a section on Earth System Science including Ocean Dynamics, Sea Level, the Coastal Ocean, Hydrology, the Cryosphere and Polar Oceans and the ‘‘Green” Ocean, extending the frontier from biogeochemistry to marine ecology. Applications are described in a subsequent section, which covers Operational Oceanography, Weather, Hurricane Wave and Wind Forecasting, Climate projection. Instruments’ development and satellite missions’ evolutions are described in a fourth section. A fifth section covers the key observations that altimeters provide and their potential complements, from other Earth observation measurements to in situ data. Section 6 identifies the data and methods and provides some accuracy and resolution requirements for the wet tropospheric correction, the orbit and other geodetic requirements, the Mean Sea Surface, Geoid and Mean Dynamic Topography, Calibration and Validation, data accuracy, data access and handling (including the DUACS system). Section 7 brings a transversal view on scales, integration, artificial intelligence, and capacity building (education and training). Section 8 reviews the programmatic issues followed by a conclusion

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.
