description: As pessoas portadoras de deficiência visual têm idênticas necessidades e desejos de participar no turismo que o público dito normal. No entanto, esta tarefa, representa para este grupo um desafio acrescido, já que a nossa sociedade está pensada para a maioria das pessoas, que não são portadoras destas deficiências. Num mundo com imensos estímulos visuais é necessário implementar estratégias que permitam às pessoas com deficiência visual usufruírem do mundo em que vivem. A necessidade de eliminar as barreiras arquitetónicas, sensoriais e sociais, adquire uma importância acrescida para fomentar a integração deste público. Os museus, recursos essenciais para a difusão da cultura, têm um papel relevante na inclusão social deste grupo. O principal objetivo deste artigo é analisar a implementação de estratégias para a melhoria da acessibilidade à interpretação de museus de Lisboa para os portadores de deficiências visuais. Constatou-se que as estratégias destinadas a aumentar a acessibilidade à interpretação para o público em geral já estão a ser implementadas na maioria dos espaços visitados. No entanto, observou-se que existem ainda muitas carências ao nível da criação de condições necessárias para que as pessoas portadoras de deficiências visuais possam usufruir da visita aos museus analisados.

description: Is V3Si a two-band or a single-band superconductor? Everyone who searches the literature for this question will find conflicting answers, for V3Si was claimed to be a perfect example of two-band and claimed to be a perfect example of single-band superconductivity. In this article we intend to clarify the situation by presenting new experimental facts acquired from the magnetic properties of a V3Si single crystal. We probe for field dependent two-band effects by analyzing the reversible magnetization at different temperatures, and we probe for temperature dependent two-band effects by analyzing the superfluid density obtained by two different methods at different magnetic fields. All our results are reliably described within the single-band models and thus support the single-band scenario for V3Si but do not completely rule out the presence of a very small second gap.

description: We describe a mechanism for order fractionalization in a two-dimensional Kondo lattice model, in which electrons interact with a gapless spin liquid of Majorana fermions described by the Yao-Lee (YL) model. When the Kondo coupling to the conduction electrons exceeds a critical value, the model develops a superconducting instability into a state where the spinor order parameter carries charge $e$ and spin $S=1/2$. The broken symmetry state develops a gapless Majorana Dirac cone in the bulk. By including an appropriate gauge string, we can show that the charge $e$, spinorial order develops off-diagonal long range order that allows electrons to coherently tunnel arbitrarily long distances through the spin liquid.

Turismo inclusivo: conceito vazio ou oportunidade de inovação em planejamento turístico?

Publisher: name: Revista Turismo & Desenvolvimento
Year: 2012

description: O presente ensaio busca contribuir, preliminarmente, para o balizamento teórico sobre o tema do turismo inclusivo, tendo como partida duas questões norteadoras: em que contexto emerge a noção de turismo inclusivo e com base em que condições este pode se configurar como real oportunidade de inovação em planejamento turístico. Metodologicamente, esta reflexão foi construída a partir de leitura e análise bibliográfica e privilegiou a inspiração brasileira sobre o tema tratado. A pesquisa bibliográfica buscou ainda resgatar a cronologia e a base teórica dos antecedentes e contradições que inspiraram a origem do conceito de turismo inclusivo e apoiar os argumentos e hipóteses levantados. Pela via de análise adotada, a noção de turismo inclusivo não representa apenas mais um rótulo em substituição ao conceito de turismo sustentável. Significa sim, uma possibilidade de inovação conceitual que exige de governos prioridade política para a questão social e que implica mudança de comportamento e atitude ética, na sociedade. Mais do que inovação conceitual, a noção de turismo inclusivo, nos moldes defendidos, pode representar oportunidade de balizamento e inspiração para práticas sustentáveis em turismo.

description: We study the fire-retaining problem on groups, a quasi-isometry invariant introduced by Martínez-Pedroza and Prytula [8], related to the firefighter problem. We prove that any Cayley graph with degree-$d$ polynomial growth does not satisfy $\{f(n)\}$-retainment, for any $f(n) = o(n^{d-2})$, matching the upper bound given for the firefighter problem for these graphs. In the exponential growth regime we prove general lower bounds for direct products and wreath products. These bounds are tight, and show that for exponential-growth groups a wide variety of behaviors is possible. In particular, we construct, for any $d\geq 1$, groups that satisfy $\{n^{d}\}$-retainment but not $o(n^d)$-retainment, as well as groups that do not satisfy sub-exponential retainment.

description: We establish linearized well-posedness of the Triple-Deck system in Gevrey-$\frac32$ regularity in the tangential variable, under concavity assumptions on the background flow. Due to the recent result \cite{DietertGV}, one cannot expect a generic improvement of the result of \cite{IyerVicol} to a weaker regularity class than real analyticity. Our approach exploits two ingredients, through an analysis of space-time modes on the Fourier-Laplace side: i) stability estimates at the vorticity level, that involve the concavity assumption and a subtle iterative scheme adapted from \cite{GVMM} ii) smoothing properties of the Benjamin-Ono like equation satisfied by the Triple-Deck flow at infinity. Interestingly, our treatment of the vorticity equation also adapts to the so-called hydrostatic Navier-Stokes equations: we show for this system a similar Gevrey-$\frac32$ linear well-posedness result for concave data, improving at the linear level the recent work \cite{MR4149066}.

description: B2 1023+25 is an extremely radio-loud quasar at z=5.3 which was first identified as a likely high-redshift blazar candidate in the SDSS+FIRST quasar catalog. Here we use the Nuclear Spectroscopic Telescope Array (NuSTAR) to investigate its non-thermal jet emission, whose high-energy component we detected in the hard X-ray energy band. The X-ray flux is ~5.5x10^(-14) erg cm^(-2)s^(-1) (5-10keV) and the photon spectral index is Gamma_X=1.3-1.6. Modeling the full spectral energy distribution, we find that the jet is oriented close to the line of sight, with a viewing angle of ~3deg, and has significant Doppler boosting, with a large bulk Lorentz factor ~13, which confirms the identification of B2 1023+25 as a blazar. B2 1023+25 is the first object at redshift larger than 5 detected by NuSTAR, demonstrating the ability of NuSTAR to investigate the early X-ray Universe and to study extremely active supermassive black holes located at very high redshift.

description: In this work we solved the time dependent Ginzburg-Landau equations to simulate homogeneous superconducting samples with square geometry for several lateral sizes. As a result of such simulations we notice that in the Meissner state, when the vortices do not penetrate the superconductor, the response of small samples are not coincident with that expected for the bulk ones, i.e., $4πM=-H$. Thus, we focused our analyzes on the way which the $M(H)$ curves approximate from the characteristic curve of bulk superconductors. With such study, we built a diagram of the size of the sample as a function of the temperature which indicates a threshold line between macroscopic and bulk behaviors.

description: The performance of quantum gates is often assessed using some form of randomized benchmarking. However, the existing methods become infeasible for more than approximately five qubits. Here we show how to use a simple and customizable class of circuits -- randomized mirror circuits -- to perform scalable, robust, and flexible randomized benchmarking of Clifford gates. We show that this technique approximately estimates the infidelity of an average many-qubit logic layer, and we use simulations of up to 225 qubits with physically realistic error rates in the range 0.1-1% to demonstrate its scalability. We then use up to 16 physical qubits of a cloud quantum computing platform to demonstrate that our technique can reveal and quantify crosstalk errors in many-qubit circuits.

description: We study the D3/probe D5 system with two domain wall hypermultiplets. The conformal symmetry can be broken by a magnetic field, B, (or running coupling) which promotes condensation of the fermions on each individual domain wall. Separation of the domain walls promotes condensation of the fermions between one wall and the other. We study the competition between these two effects showing a first order phase transition when the separation is ~ 0.56 lambda^1/4 B^-1/2. We identify extremal brane configurations which exhibit both condensations simultaneously but they are not the preferred ground state.

description: Most back hole and neutron star progenitors are found in triples or higher multiplicity systems. Here, we present a new triple stellar evolution code, ${\tt TSE}$, which simultaneously takes into account the physics of the stars and their gravitational interaction. ${\tt TSE}$ is used to simulate the evolution of massive stellar triples in the galactic field from the zero-age-main-sequence until they form compact objects. To this end, we implement initial conditions that incorporate the observed high correlation between the orbital parameters of early-type stars. We show that the interaction with a tertiary companion can significantly impact the evolution of the inner binary. High eccentricities can be induced by the third-body dynamical effects, leading to a Roche lobe overflow or even to a stellar merger from initial binary separations $~10^3$ - $10^5\,\rm R_\odot$. In $\sim5\,\%$ of the systems the tertiary companion itself fills its Roche lobe, while $\sim 10\,\%$ of all systems become dynamically unstable. We find that between $0.3\%$ and $5\%$ of systems form a stable triple with an inner compact object binary, where the exact fraction depends on metallicity and the natal kick prescription. The vast majority of these triples are binary black holes with black hole companions. We find no binary neutron star in any surviving triple, unless zero natal kicks are assumed. About half of all black hole binaries formed in our models are in triples, where in the majority the tertiary black hole is able to perturb their long-term evolution. Our results show that triple interactions are key to a full understanding of massive star evolution and compact object binary formation.

Incorporating the influence of sub-grid heterogeneity in regional-scale contaminant transport models

description: Numerical transport models based on the advection-dispersion equation (ADE) are built on the assumption that sub-grid cell transport is Fickian such that dispersive spreading around the average velocity is symmetric and without significant tailing on the front edge of a solute plume. However, anomalous diffusion in the form of super-diffusion due to preferential pathways in an aquifer has been observed in field data, challenging the assumption of Fickian dispersion at the local scale. This study develops a fully Lagrangian method to simulate sub-grid super-diffusion in a multi-dimensional regional-scale transport. The underlying concept is based on previous observations that solutions to space-fractional ADEs, which can describe super-diffusive dispersion, can be obtained by transforming solutions of classical ADEs. The transformations are equivalent to randomizing particle travel time or relative velocity for each model time step. Here, the time randomizing procedure known as subordination is applied to flow field output from MODFLOW simulations. Numerical tests check the applicability of the novel method in mapping regional-scale super-diffusive transport conditioned on local properties of multi-dimensional heterogeneous media.

description: We combine IRAM Plateau de Bure Interferometer and Herschel PACS and SPIRE measurements to study the dust and gas contents of high-redshift star forming galaxies. We present new observations for a sample of 17 lensed galaxies at z=1.4-3.1, which allow us to directly probe the cold ISM of normal star-forming galaxies with stellar masses of ~10^10Msun, a regime otherwise not (yet) accessible by individual detections in Herschel and molecular gas studies. The lensed galaxies are combined with reference samples of sub-millimeter and normal z~1-2 star-forming galaxies with similar far-infrared photometry to study the gas and dust properties of galaxies in the SFR-M*-redshift parameter space. The mean gas depletion timescale of main sequence galaxies at z>2 is measured to be only ~450Myr, a factor of ~1.5 (~5) shorter than at z=1 (z=0), in agreement with a (1+z)^-1 scaling. The mean gas mass fraction at z=2.8 is 40+/-15% (44% after incompleteness correction), suggesting a flattening or even a reversal of the trend of increasing gas fractions with redshift recently observed up to z~2. The depletion timescale and gas fractions of the z>2 normal star-forming galaxies can be explained under the "equilibrium model" for galaxy evolution, in which the gas reservoir of galaxies is the primary driver of the redshift evolution of specific star formation rates. Due to their high star formation efficiencies and low metallicities, the z>2 lensed galaxies have warm dust despite being located on the star formation main sequence. At fixed metallicity, they also have a gas-to-dust ratio 1.7 times larger than observed locally when using the same standard techniques, suggesting that applying the local calibration of the relation between gas-to-dust ratio and metallicity to infer the molecular gas mass of high redshift galaxies may lead to systematic differences with CO-based estimates.

description: Bayesian statistical inference is a powerful tool for model-data comparisons and extractions of physical parameters that are often unknown functions of system variables. Existing Bayesian analyses often rely on explicit parametrizations of the unknown function. It can introduce long-range correlations that impose fictitious constraints on physical parameters in regions of the variable space that are not probed by the experimental data. We develop an information field (IF) approach to modeling the prior distribution of the unknown function that is free of long-range correlations. We apply the IF approach to the first global Bayesian inference of the jet transport coefficient $\hat q$ as a function of temperature ($T$) from all existing experimental data on single-inclusive hadron, di-hadron and $γ$-hadron spectra in heavy-ion collisions at RHIC and LHC energies. The extracted $\hat q/T^3$ exhibits a strong $T$-dependence as a result of the progressive constraining power when data from more central collisions and at higher colliding energies are incrementally included. The IF method guarantees that the extracted $T$-dependence is not biased by a specific functional form.

description: O stress afeta negativamente a vida de muitas pessoas na sociedade moderna, causando mal-estar, doenças, deteriorando o desempenho diário e diminuindo toda a qualidade de vida. A população com incapacidade estará, provavelmente, mais exposta a diferentes e mais intensas circunstâncias indutoras de stress, que poderão causar uma instabilidade, ainda mais severa, ao nível dos seus recursos mentais, psicológicos, emocionais e até físicos. As evidências empíricas demonstram que o lazer suscita sentimentos de liberdade e desenvolvimento pessoal, ilustrando o seu potencial para a redução e controlo do stress, pela indução de interação social, emoções positivas, e do coping face a situações de stress (Folkman e Moskowitz, 2004). Como o turismo é reconhecido como uma fonte de impactos positivos, de longo prazo, na qualidade de vida dos seus participantes (Neal et al., 2007) sendo também associado à redução do stress, decidiu-se estudar os aspetos intrínsecos desta atividade para o combate ao stress, na perspetiva das pessoas com incapacidade. O presente trabalho pretende clarificar as circunstâncias indutoras de stress para as pessoas com incapacidade e explicar como o turismo poderá atuar no âmbito do stress-coping. Assim, apresentar-se-á a revisão da literatura referente à temática em estudo, bem como os resultados obtidos da análise de focus groups realizados no contexto de um estudo exploratório sobre a participação de pessoas com incapacidade na atividade turística.

description: Photometric redshifts are commonly used to measure the distribution of galaxies in large surveys. However, the demands of ongoing and future large-scale cosmology surveys place very stringent limits on the redshift performance that are difficult to meet. A new approach to meet this precision need is forward modelling, which is underpinned by realistic simulations. In the work presented here, we use simulations to study the sensitivity of redshift distributions to the underlying galaxy population demographics. We do this by varying the redshift evolving parameters of the Schechter function for two galaxy populations, star-forming and quenched galaxies. Each population is characterised by eight parameters. We find that the redshift distribution of shallow surveys, such as SDSS, is mainly sensitive to the parameters for quenched galaxies. However, for deeper surveys such as DES and HSC, the star-forming parameters have a stronger impact on the redshift distribution. Specifically, the slope of the characteristic magnitude, $a_\mathrm{M}$, for star-forming galaxies has overall the strongest impact on the redshift distribution. Decreasing $a_\mathrm{M}$ by 148 per cent (its given uncertainty) shifts the mean redshift by ${\sim} 45$ per cent. We explore which combination of colour and magnitude measurements are most sensitive to $a_\mathrm{M}$ and we find that each colour-magnitude pair studied is similarly affected by a modification of $a_\mathrm{M}$.

description: We consider a quantum oscillator coupled to a bath of $N$ other oscillators. The total system evolves with a quasi-Hermitian Hamiltonian. Associated to it is a family of Hermitian systems, parameterized by a unitary map $W$. Our main goal is to find the influence of $W$ on the entropy and the entanglement in the Hermitian systems. We calculate explicitly the reduced density matrix of the single oscillator for all Hermitian systems and show that, regardless of $W$, their von Neumann entropy oscillates with a common period which is twice that of the non-Hermitian system. We show that generically, the oscillator and the bath are entangled for almost all times. While the amount of entanglement depends on the choice of $W$, it is independent of $W$ when averaged over a period. These results describe some universality in the physical properties of all Hermitian systems associated to a given non-Hermitian one.

É notório que, a maioria dos promotores anseia que a atividade cresça, pelo menos, até determinado patamar. Contudo, as atividades de marketing são menosprezadas pelos promotores, sendo que são os promotores que não se preocupam na definição de objetivos económicos, aqueles que mais as desconsideram.

description: We consider the classical problem of the stick-slip dynamics observed when peeling a roller adhesive tape at a constant velocity. From fast imaging recordings, we extract the dependencies of the stick and slip phases durations with the imposed peeling velocity and peeled ribbon length. Predictions of Maugis and Barquins [in Adhesion 12, edited by K.W. Allen, Elsevier ASP, London, 1988, pp. 205--222] based on a quasistatic assumption succeed to describe quantitatively our measurements of the stick phase duration. Such model however fails to predict the full stick-slip cycle duration, revealing strong dynamical effects during the slip phase.

description: O turismo no espaço rural apresenta-se como uma prática no contexto da pluriatividade que se desenvolve nos espaços rurais, introduzindo o setor de serviços à propriedade rural. Surge, então, o turismo rural comunitário como opção de desenvolvimento em comunidades rurais que mantêm características étnico-culturais, cuja motivação de visitação seja a cultura. O presente estudo investigou o desenvolvimento do turismo rural a partir das percepções da população do Catu, Rio Grande do Norte, Brasil. A área pesquisada é uma comunidade rural, cujo rio do mesmo nome a separa geograficamente em dois municípios, e que tem como base econômica a agricultura familiar. É considerada um remanescente da cultura indígena dos Eleotérios no Rio Grande do Norte. O potencial turístico local é significativo, considerando os atrativos culturais e naturais existentes. A pesquisa se configurou como exploratória de abordagem qualitativa. A estratégia de pesquisa utilizada foi o estudo de caso, sendo o universo determinado por amostragem não probabilística intencional e a coleta de dados feita através de entrevistas e observação participante. Constatou-se que poucos são aqueles que compreendem o verdadeiro significado do turismo no espaço rural, apesar de saberem elencar os atrativos do local. Para os moradores o turismo é bem-vindo, fomentará mudanças e auxiliará na manutenção dos aspectos étnico-culturais.

description: We investigate the quantization problem of $(-1)$-shifted derived Poisson manifolds in terms of $\BV_\infty$-operators on the space of Berezinian half-densities. We prove that quantizing such a $(-1)$-shifted derived Poisson manifold is equivalent to the lifting of a consecutive sequences of Maurer-Cartan elements of short exact sequences of differential graded Lie algebras, where the obstruction is a certain class in the second Poisson cohomology. Consequently, a $(-1)$-shifted derived Poisson manifold is quantizable if the second Poisson cohomology group vanishes. We also prove that for any $Ł$-algebroid $\Cc{\aV}$, its corresponding linear $(-1)$-shifted derived Poisson manifold $\Cc{\aV}^\vee[-1]$ admits a canonical quantization. Finally, given a Lie algebroid $A$ and a one-cocycle $s\in \sections{A^\vee}$, the $(-1)$-shifted derived Poisson manifold corresponding to the derived intersection of coisotropic submanifolds determined by the graph of $s$ and the zero section of the Lie Poisson $A^\vee$ is shown to admit a canonical quantization in terms of Evens-Lu-Weinstein module.

description: We measure a significant correlation between the thermal Sunyaev-Zel'dovich effect in the Planck and WMAP maps and an X-ray cluster map based on ROSAT. We use the 100, 143 and 343 GHz Planck maps and the WMAP 94 GHz map to obtain this cluster cross spectrum. We check our measurements for contamination from dusty galaxies using the cross correlations with the 220, 545 and 843 GHz maps from Planck. Our measurement yields a direct characterization of the cluster power spectrum over a wide range of angular scales that is consistent with large cosmological simulations. The amplitude of this signal depends on cosmological parameters that determine the growth of structure (σ_8 and Ω_M) and scales as σ_8^7.4 and Ω_M^1.9 around the multipole (ell) ~ 1000. We constrain σ_8 and Ω_M from the cross-power spectrum to be σ_8 (Ω_M/0.30)^0.26 = 0.8 +/- 0.02. Since this cross spectrum produces a tight constraint in the σ_8 and Ω_M plane the errors on a σ_8 constraint will be mostly limited by the uncertainties from external constraints. Future cluster catalogs, like those from eRosita and LSST, and pointed multi-wavelength observations of clusters will improve the constraining power of this cross spectrum measurement. In principle this analysis can be extended beyond σ_8 and Ω_M to constrain dark energy or the sum of the neutrino masses.

description: Mach cones are expected to form in the expanding quark-gluon plasma (QGP) when energetic quarks and gluons (called jets) traverse the hot medium at a velocity faster than the speed of sound in high-energy heavy-ion collisions. The shape of the Mach cone and the associated diffusion wake are sensitive to the initial jet production location and the jet propagation direction relative to the radial flow because of the distortion by the collective expansion of the QGP and large density gradient. The shape of jet-induced Mach cones and their distortions in heavy-ion collisions provide a unique and direct probe of the dynamical evolution and the equation of state of QGP. However, it is difficult to identify the Mach cone and the diffusion wake in current experimental measurements of final hadron distributions because they are averaged over all possible initial jet production locations and propagation directions. To overcome this difficulty, we develop a deep learning assisted jet tomography which uses the full information of the final hadrons from jets to localize the initial jet production positions. This method can help to constrain the initial regions of jet production in heavy-ion collisions and enable a differential study of Mach-cones with different jet path length and orientation relative to the radial flow of the QGP in heavy-ion collisions.

description: We prove a new convergence condition for the activity expansion of correlation functions in equilibrium statistical mechanics with possibly negative pair potentials. For non-negative pair potentials, the criterion is an if and only if condition. The condition is formulated with a sign-flipped Kirkwood-Salsburg operator and known conditions such as Koteck${ý}$-Preiss and Fern${á}$ndez-Procacci are easily recovered. In addition, we deduce new sufficient convergence conditions for hard-core systems in $\mathbb R^d$ and $\mathbb Z^d$ as well as for abstract polymer systems. The latter improves on the Fern${á}$ndez-Procacci criterion.

description: Ao longo de mais de meio século, o rural tem conhecido múltiplas transformações, algumas das quais levaram a que parte dos territórios que nele se incluem venham assumindo processos mais ou menos profundos de reinvenção e recriação. O mesmo acontece com Paredes do Rio, aldeia barrosã, situada na freguesia de Covelães, concelho de Montalegre e sobre a qual recai este artigo, no qual pretendemos dar conta de um projeto de investigação nascido do fascínio e interesse que temos pela região do Barroso. Com ele pretendíamos encontrar respostas para a questão que então se nos colocou, de forma a sabermos se a revitalização das tradições, desde que aliada à cultura e à animação, poderia ser um foco de atração de turistas àquela aldeia. A metodologia utilizada na investigação foi de cariz quantitativo, com recurso ao inquérito por questionário e os resultados que com ele conseguimos refletem que a dinamização de experiências e vivências culturais, como a de recriar as tradições, permitem a quem visita, experienciar uma vivência sociocultural que se materializa no afeto e na forma como se é recebido. Os resultados obtidos confirmam as hipóteses de partida, cabe, no entanto, à comunidade decidir o caminho por onde quer enveredar, na certeza de que se esse caminho for o do turismo, tem de se preparar para os desafios que essa sua decisão coloca.

description: The production cross-section of $^{68}$Ge, $^{69}$Ge, $^{65}$Zn and $^{67}$Ga radioisotopes from alpha-induced nuclear reaction with $^{nat}$Zn have been measured using the stacked foil activation technique followed by the off-line $γ$-ray spectroscopy in the incident alpha energy range 14-37 MeV. The obtained nuclear reaction cross-sections are compared with previous experimental data available in the EXFOR data library, evaluated nuclear data from TENDL-2019 and theoretical results, calculated using TALYS nuclear reaction code. We have also performed the detailed uncertainty analysis for these nuclear reactions and their respective correlation metrics are presented. Since $α$-induced reactions are important in nuclear medicine and developing the nuclear reaction codes so needful corrections related to the coincidence summing factor and the geometric factor have been considered during the data analysis in the present study.

description: O uso do turismo no espaço rural tem aumentado significativamente, resultante, principalmente, de novas reproduções socioeconômicas e da implantação de pluriatividades no campo. Apesar de evidenciar melhorias na qualidade de vida, na auto-estima, na valorização da cultura e do ambiente, uma das questões mais preocupantes para a gestão do turismo é a geração e destino de resíduos sólidos no espaço rural. Diante disso, o estudo objetiva analisar a ação dos empreendedores e do poder público na gestão dos resíduos sólidos produzidos nos empreendimentos turísticos que compõem a Rota Germânica no Sul do Brasil. Para tanto, busca-se identificar a necessidade de uma gestão ambiental eficiente para as propriedades; identificar quais propriedades rurais investem em saneamento, bem como, diagnosticar a realidade do comportamento ambiental dos empreendedores do turismo no espaço rural. O estudo é quali-quantitativo e contempla uma fase exploratória e outra descritiva. A pesquisa é um estudo de caso e a coleta de dados foi feita a partir de entrevistas semi-estruturadas aos proprietários rurais da Rota. Como resultado, obteve-se que poucas propriedades rurais investiram em saneamento. Por fim, identifica-se a necessidade de implantação de programas de sensibilização local para minimizar a geração e destino de resíduos sólidos, premissa para a continuidade da atividade turística no espaço pesquisado.

description: Optical imaging through scattering media is a long-standing challenge. Although many approaches have been developed to focus light or image objects through scattering media, they are either invasive, restricted to stationary or slowly-moving media, or require high-resolution cameras and complex algorithms to retrieve the images. Here we introduce a computational imaging technique that can overcome these restrictions by exploiting spatial-temporal encoded patterns (STEP). We present non-invasive imaging through scattering media with a single-pixel photodetector. We show that the method is insensitive to the motions of media. We further demonstrate that our image reconstruction algorithm is much more efficient than correlation-based algorithms for single-pixel imaging, which may allow fast imaging in currently unreachable scenarios.
