The observed period decrease can be plausibly explained by a combination of the mass transfer from the primary to the secondary and angular momentum loss via magnetic braking.

The cyclic period oscillation suggests that BI CVn is a triple system containing a tertiary component with a mass no less than 0. As in the cases of the other contact binaries e. The classical explosive basaltic eruption spectrum is traditionally defined by the following end member eruption styles: Hawaiian and Strombolian. The field use of high-speed cameras has enabled volcanologists to make improved quantifications and more accurate descriptions of these classical eruptions styles and to quantify previously undecipherable activity including activity on the basaltic eruption spectrum between the two defined end members.

Explosive activity in at the free surface of the Halema' uma 'u lava lake at Kilauea exhibited features of both sustained Hawaiian fountaining and transient Strombolian explosivity. Most of this activity is internally triggered by the internal rise of decoupled gas bubbles from below the lake's surface, but external triggering via rock falls, was also observed.

Here I identify three styles of bubble bursting and spattering eruptive activity isolated events, clusters of events, and prolonged episodes at the lava lake, and distinguished them based on their temporal and spatial distributions. Isolated events are discrete single bubble bursts that persist for a few tenths of seconds to seconds and are separated by repose periods of similar or longer time scales.

Cluster of events are closely spaced, repeated events grouped around a narrow point source, which persist for seconds to minutes. Prolonged episodes are groupings of numerous events closely linked in space and time that persist for tens of minutes to hours. Analysis of individual events from high-speed camera images indicates that they are made up of up to three phases: the bubble ascent phase, the bursting and pyroclast ejection phase, and the drain back and rebound phase.

Based on the numerical parameters established in this study, the activity was relatively weak i. We present a detailed analysis of the interesting W UMa binary FI Boo in view of the spectroscopic signature of a third body through photometry, period variation, and a thorough investigation of solution uniqueness. The results were tested by heuristic scanning and parameter kicking to provide the consistent and reliable set of parameters that was used to obtain the initial masses of the progenitors 1.

We also investigated the evolutionary status of massive components with several sets of widely used isochrones. However, it has been neglected in photometric investigations. Here, the first complete light curves in the B, V, R, and I bands are presented and analyzed using the Wilson and Devinney method. The continuous increase may be caused by a mass transfer from the less massive component to the more massive one. This suggests that UZ CMi is in the thermal relaxation oscillation controlled stage of the evolutionary scheme proposed by Qian. UZ CMi will oscillate around a critical mass ratio and the contact configuration cannot be broken.

The cyclic change was analyzed for the light-travel time effect via the presence of an extremely cool stellar companion. The formation, evolution, collapse, and subsequent resurrection of a vent within Halema' uma 'u Crater, Kilauea Volcano, produced energetic and varied degassing signals recorded by a nearby infrasound array between and early After 25 years of quiescence, a vent-clearing explosive burst on 19 March produced a clear, complex acoustic signal.

Near-continuous harmonic infrasonic tremor followed this burst until 4 December , when a period of decreased degassing occurred. The tremor spectra suggest volume oscillation and reverberation of a shallow gas-filled cavity beneath the vent. The dominant tremor peak can be sustained through Helmholtz oscillations of the cavity, while the secondary tremor peak and overtones are interpreted assuming acoustic resonance.

The dominant tremor frequency matches the oscillation frequency of the gas emanating from the vent observed by video. Over 21 varied degassing bursts were observed with extended burst durations and frequency content consistent with a transient release of gas exciting the cavity into resonance. Correlation of infrasound with seismicity suggests an open system connecting the atmosphere to the seismic excitation process at depth.

Numerous degassing bursts produced very long period 0. Kilauea infrasound appears controlled by the exsolution of gas from the magma, and the interaction of this gas with the conduits and cavities confining it. Using the lava lake as the hot background source we present MWIR gas analysis of the Kilauea volcanic plume.

In order to construct the O-C diagram to analyze the period change of UY UMa , we have performed a careful search for all available times of light minima. A total of 76 times of light minima were collected and listed in Table 2. The minimum scatter, 0. The light travel effect produced by the presence of tertiary components can reveal much about the origin and evolution of over-contact binaries.

Progress in the analysis of eclipse timing variations is summarized here both from the empirical and the theoretical points of view, and a more extensive investigation of the proposed orbital parameters of third bodies is proposed. The code we have developed for this, implemented in Python, is set up to handle heuristic scanning with parameter perturbation in parameter space, and to establish realistic uncertainties from the least squares fitting. Future options to be implemented include MCMC and bootstrapping.

Raulin, J. We present the first precision BVRI light curves, synthetic light curve solutions, and a period study for the high amplitude solar type binary, V Cygni. The light curves have the appearance of an Algol EA type; however, it is made up of dwarf solar type components in a detached mode with a period of only 0. Flare-like disruptions occur in the light curves following the primary and secondary eclipses possibly due to the line-of-sight track of a gas stream.

The more massive star is the gainer, making this system a classic, albeit dwarf, Algol. Survey of period variations of superhumps in SU UMa -type dwarf novae. The eighth year Continuing the project described by Kato et al. The data have improved the distribution of orbital periods, the relation between the orbital period and the variation of superhumps, and the relation between period variations and the rebrightening type in WZ Sge-type objects.

Coupled with new measurements of mass ratios using growing stages of superhumps, we now have a clearer and statistically greatly improved evolutionary path near the terminal stage of evolution of cataclysmic variables. We have newly obtained superhump periods for 79 objects and 13 orbital periods, including periods from early superhumps. In order that future observations will be more astrophysically beneficial and rewarding to observers, we propose guidelines on how to organize observations of various superoutbursts. The measurements were obtained using inch and 1-inch telescopes, respectively.

The observations were performed at the Masaryk University Observatory in Brno 3 nights, inch , and at the private observatory in Brno 16 nights, 1-inch in the Czech Republic from December to June Exposures were v - 60s, b - 30s, y - 30s, green - 30s. For the small aperture telescope, five frames were combined to a single image to achieve a better signal-to-noise ratio. The time resolution of a such combined frame is about s.

CCD images were calibrated in a standard way dark frame and flat field corrections. The C-Munipack software Motl was used for this processing as well as for differential photometry. The 4th file contains minima timings of eclipsing binary CL Aur. Caretta, C. A revised ephemeris and updated orbital period for EQ Tau have been determined from newly acquired CCD-derived photometric data.

A Roche-type model based on the Wilson-Devinney code produced simultaneous theoretical fits of light curve data in three passbands by invoking cold spots on the primary component. These new model fits, along with similar light curve data for EQ Tau collected during the previous six seasons , provided a rare opportunity to follow the seasonal appearance of star spots on a W UMa binary system over nine consecutive years.

Fixed values for q,? With the exception of the season all other light curves produced since then required a spotted solution to address the flux asymmetry exhibited by this binary system at Max I and Max II. At least one cold spot on the primary appears in seven out of twelve light curves for EQ Tau produced over the last nine years, whereas in six instances two cold spots on the primary star were invoked to improve the model fit.

Solutions using a hot spot were less common and involved positioning a single spot on the primary constituent during the , , and seasons. In many industrial areas such as in food, pharmaceutical, cosmetic, printing, and textile, the use of synthetic dyes has been integral with products such as azo dye, anthrax, and dyestuffs. As such, these industries produce a lot of waste by-products that could contaminate the environment.

Bioremediation, therefore, has become an important emerging technology due to its cost-sustainable, effective, natural approach to cleaning up contaminated groundwater and soil via the use of microorganisms. The use of microorganisms in bioremediation requires the optimisation of parameters used in cultivating the organism. Biodegradation analyses were carried out on a soil spiked with RBBR and supplemented with rice husk as the fungus growth enhancer. A two-level Plackett-Burman design was used to screen the medium components for the effects on the decolourization of RBBR.

There was a moderate positive correlation between surgical complications and survival or death. The number of surgical patients is lower compared to reference centres for cardiovascular surgery. There is a marked tendency to perform corrective and palliative surgeries in specific disease in patients with added risk or 'bad' cardiac anatomy that prevent full correction at the first attempt. Prospective epidemiological and clinical studies should be conducted to understand the behaviour of congenital heart diseases treated in the region. The orbital period decrease was found to be a rate of The inner and outer critical Roche lobes will contract and cause the contact degree to increase.

Therefore, IK Boo may evolve into a deeper contact system. Furthermore, a possible cyclic variation was found with a period of 9. Speciation, population structure, and demographic history of the Mojave Fringe-toed Lizard Uma scoparia , a species of conservation concern. The North American deserts were impacted by both Neogene plate tectonics and Quaternary climatic fluctuations, yet it remains unclear how these events influenced speciation in this region. We tested published hypotheses regarding the timing and mode of speciation, population structure, and demographic history of the Mojave Fringe-toed Lizard Uma scoparia , a sand dune specialist endemic to the Mojave Desert of California and Arizona.

We sampled individual lizards representing 22 insular dune localities, obtained DNA sequences for 14 nuclear loci, and found that U. Analyses of genotypes using Bayesian clustering algorithms did not identify discrete populations within U. Using isolation-with-migration IM models and a novel coalescent-based hypothesis testing approach, we estimated that U. The likelihood ratio test and the Akaike Information Criterion consistently rejected nested speciation models that included parameters for migration and population growth of U.

We reject the Neogene vicariance hypothesis for the speciation of U. It is a high-amplitude V 0. As expected, the light curve is asymmetric due to spot activity. Three times of minimum light were calculated, for two primary eclipses and one secondary eclipse, from our present observations. In total, some 26 times of minimum light covering nearly 20 years of observation were used to determine linear and quadratic ephemerides. It is noted that the light curve solution remained in a detached state for every iteration of the computer runs.

A degree radius high latitude white spot faculae was iterated on the primary component. Three new precise epochs of minimum light were determined and a linear and a quadratic ephemeris were computed from these and previous data covering 28 years of observation. The light curves reveal that the system undergoes a brief 20 min totality in the primary eclipse, indicating that CE Leo is a W UMa W-type binary. Standard magnitudes were found and a simultaneous solution of the B, V, R, I light curves was computed using the new Wilson-Devinney synthetic light curve code which has the capability of automatically adjusting star spots.

The solution indicates that the system consists of two early K-type dwarfs in marginal contact with a fill-out factor less than 3 percent. Evidence for the presence of a large 45 deg radius superluminous area on the cooler component is given. Environmental differences in substrate mechanics do not affect sprinting performance in sand lizards Uma scoparia and Callisaurus draconoides. Running performance depends on a mechanical interaction between the feet of an animal and the substrate.

This interaction may differ between two species of sand lizard from the Mojave Desert that have different locomotor morphologies and habitat distributions. Uma scorparia possesses toe fringes and inhabits dunes, whereas the closely related Callisaurus draconoides lacks fringes and is found on dune and wash habitats. The present study evaluated whether these distribution patterns are related to differential locomotor performance on the fine sand of the dunes and the course sand of the wash habitat.

We measured the kinematics of sprinting and characterized differences in grain size distribution and surface strength of the soil in both habitats. Although wash sand had a surface strength The broadly distributed C. Furthermore, there were no significant differences in maximum acceleration or the time to attain maximum speed between species or between substrates. These results suggest that differences in habitat distribution between these species are not related to locomotor performance and that sprinting ability is dominated neither by environmental differences in substrate nor the presence of toe fringes.

Size-resolved chemistry of aerosols produced by Halema' uma 'u eruption , Kilauea Volcano, Hawai'i. A dense quiescent plume has been emitted continuously from the eruptive vent in Halema' uma 'u crater since March Aerosol particles were sampled near-source in the young plume uma 'u and Pu'u O'o show SO in the same narrow size bin 0.

It is noteworthy that the particles appear not to have grown when the plume has drifted km downwind. The formation of aerosol measured downwind is dominated by oxidation of SO2 to SO in the plume. Um total de 5. These solar-type systems are usually detached or semidetached with one or both components under filling their critical Roche lobes. They usually have EA or EB-type light curves unequal eclipse depths, indicating components with substantially different temperatures.

The accepted scenario for these W UMa binaries is that they are undergoing steady but slow angular momentum losses due to magnetic braking as stellar winds blow radially away on stiff bipolar field lines. These binaries are believed to come into stable contact and eventually coalesce into blue straggler type, single, fast rotating A-type stars Guinan and Bradstreet, This is the shortest period PCWB found so far. Our solutions of light curves separated by some three years give approximately the same physical parameters. However the spots radically change, in temperature, area and position causing a distinctive variation in the shape of the light curves.

We conclude that spots are very active on this solar type dwarf system and that it may mimic its larger cousins, the RS CVn binaries. New photometric observations of a W UMa system, V Aur, were carried out over 10 nights from December 19 to February 8, from which four sets of light curves were obtained. The light curves show many unusual behavioral features, including changing occultation depths, transit minima, and asymmetric maxima. The four sets of light curves have been separately analyzed with the Wilson-Devinney method.

The results suggest a totally eclipsing contact configuration for the system. Over a surprisingly short time span of only 52 days, the dominant spot distortion phase jumped twice between phases 0. The light-curve variations can be interpreted by the presence of two cool spots on the massive component. Our study demonstrates that the system has been undergoing typical flip-flop activity. Lineage diversification of fringe-toed lizards Phrynosomatidae: Uma notata complex in the Colorado Desert: Delimiting species in the presence of gene flow.

Gottscho, Andrew D. Multi-locus nuclear DNA data were used to delimit species of fringe-toed lizards of the Uma notata complex, which are specialized for living in wind-blown sand habitats in the deserts of southwestern North America, and to infer whether Quaternary glacial cycles or Tertiary geological events were important in shaping the historical biogeography of this group. We analyzed ten nuclear loci collected using Sanger sequencing and genome-wide sequence and single-nucleotide polymorphism SNP data collected using restriction-associated DNA RAD sequencing.

Uma notata, U. Therefore, we conservatively delimit four species-level lineages within this complex U. Both concatenated and coalescent-based estimates of speciation times support the hypotheses that speciation within the complex occurred during the late Pleistocene, and that the geological evolution of the Colorado River delta during this period was an important process shaping the observed phylogeographic patterns. O primeiro eixo integra o tema no desenvolvimento cultural do ser humano, praticando a interdisciplinaridade.

No trabalho discutimos em detalhe as quatro etapas. Houghton, B. The summit eruption within Halema' uma 'u crater, Kilauea has been characterized by alternations of passive degassing with two styles of explosive activity, both frequently triggered by rock falls that perturb the free surface of magma in the vent. In the first, larger rock falls trigger second vesiculation of magma at depths up to m below the free surface ejecting juvenile bomb and lapilli populations of very variable vesicularity. The second, the topic of this presentation, consists of intervals of minutes to tens-of-minutes duration of low fountaining activity often from multiple locations.

Vents may migrate with time, first across the free surface to its margins, and then around the margins, in response to convection processes in the underlying melt. Analysis of short sequences of high-speed, high-resolution video footage shows that the sustained fountaining is maintained by not by a continuous discharge but rather by closely spaced bursting of two-to-five meter-wide bubbles.

CRTS J The light curve contains one superoutburst, eight normal outbursts including a precursor to the superoutburst , and several minioutbursts that are present before—but not after—the superoutburst. The superoutburst began with a precursor normal outburst, and shortly after the peak of the precursor, the system developed large-amplitude superhumps that achieved their maximum amplitude after just three superhump cycles. The period excess of the initial superhump period relative to the orbital period implies a mass ratio of 0.

This paper presents one of the concepts of Astronomy and its consequent failure in teaching this topic in high school, even when the official documents point out the necessity of Astronomy teaching at this school level. Among the spontaneous conceptions in Astronomy that high school students carry with them, even after the end of the school, we emphasized in this research the Moon phases.

    The development of different strategies in relation to traditional methods, aimed to teaching-learning process on this topic was considered in this study. These strategies were devised based on the reference frame of the Meaningful Learning, as elaborated by Ausubel. The proposals presented here include the active participation of students in experimental activities and other didactic activities, for their continuous evaluation during the process.

    These activities finished with a Comics elaboration about the Moon phases. Therefore, the objective of this paper is to present a proposal for differentiated teaching activity about Moon phases supported by the theoretical principles of Meaningful Learning at Physics classes. A time of minimum light of HJD Using Wilson-Devinney's binary model, we analized the light curves.

A single, precise moment of the primary eclipse confirms the progressive shortening of the orbital period. The emergence of hyaluronic acid dermal fillers with lidocaine has transformed the minimally invasive treatment of wrinkles, lines and folds of the face.

    Patients can be treated quickly, painlessly and without the need for large doses of lidocaine. Therefore, it is important to scientifically evaluate the merits of lidocaine-containing products over those without. Only 73 subjects completed the follow-up. There were 68 females and 5 males with medium-to-deep nasolabial folds. All subjects were randomly injected with the two products on one or the other side of the face. Both products achieved significant improvement in the wrinkle severity score.

    Overall results were slightly better with UJU due to ease of injection, lack of pain and avoidance of topical or parenteral anaesthetic. In all other respects, differences in clinical data were not statistically significant. We verified the number of questions addressing this topic that were present over the years, as well as the most recurrent subjects. We discussed the results from what is proposed by the official documents regarding the teaching of Astronomy in the Elementary and Secondary Education and we entertain future expectations about the presence of contents of this science in future official examinations.

    This is a report of an activity of introduction to the study of Astronomy developed with a group of future Physics teachers at a Brazilian public university. Such activity had the goal of giving privileged emphasis to notions of spatiality, alternative conceptions of the participants and the process of interaction among peers, and consisted of the representation, in a three dimensional space, of the models of the universe that the participants had. The results, which were categorized as miscellaneous, geocentric, heliocentric and acentric models of the universe, were qualitatively analyzed.

    Analyses of the activity in the perspective of the participants are indicated and additional considerations are made regarding its use as a resource for teaching Astronomy and for teacher training. The experiences of pregnant women at an advanced maternal age: an integrative review. To identify in the literature how the experiences of women age 35 or above are described in terms of pregnancy. Eighteen studies that dealt with the experiences of pregnant women at an advanced maternal age were selected and analyzed.

    The studies evidenced four theme categories: the search for information, which pointed to a deficit of information supplied by health care professionals; perceiving the risks, which pointed to women's concerns about their own health and their children's; the ideal moment for motherhood, with different reasons for postponing it; and adjusting to a new routine, showing a concern regarding changes in daily life. From the results, it was possible to understand that other factors, in addition to those that include risks, are present in the experiences of older pregnant women and point to a need to involve such aspects in nursing care to create comprehensive strategies that are aligned with these women's needs.

    A Diagnostic Assessment for the Teaching of Astronomy. This article presents results of a research which aimed to understand the meanings that people construct for astronomical observation. The subjects, students and school teachers, initially received some instruction on how to view astronomical objects through the telescope.

    After the observation was realized, they were interviewed.

    The data analysis allowed the creation of 12 categories, later interpreted on the basis of relationship with knowledge relation to the world, with himself and with others , as presented by Bernard Charlot. Associated factors with mammographic changes in women undergoing breast cancer screening. As melhoras, depois de normalizadas, do desempenho dos estudantes nos dois quesitos foram pequenas, 0. New ephemeris and the absolute parameters—masses, radii and luminosities—of the contact systems VW LMi and BX Dra have been obtained, by means of the analysis of the minima data available in the literature for the determination of the ephemeris and combining the previously published spectroscopic information and the results of the Wilson-Devinney method using photometric data for the determination of the absolute parameters.

    Masses of the VW LMi contact system primary and secondary components are 1. The corresponding radii are 1.

    For the BX Dra contact system the masses are 2. In both cases, the estimated luminosities seem to be slightly greater that the values derived from the Hipparcos distances. Congenital heart defects are common in infants and adults, affecting quality of life if not corrected. Unlike open surgery, percutaneous intervention allows correction with a high success rate and speedy recovery.

    In Mexico, there are not enough studies to describe their efficacy and safety. A cohort study was conducted in the Hospital "Manuel Avila Camacho", in Puebla, Mexico, including patients with congenital heart defects repaired by percutaneous intervention, recording data from clinical records. The following were documented: post-guided fluoroscopy, hemodynamic changes, cardiac catheterization drilling anatomical changes, and complications six months later such as infection or bleeding at the puncture site, device migration, endocarditis, or death.

    SPSS was used, using descriptive and inferential statistics. The patients' congenital heart defects treated were ductus arteriosus, atrial septal defect, and aortic coarctation, with ductus arteriosus being recorded as the most frequent congenital heart defect. Anatomical corrections of congenital defects were successful in VZ Psc is a W-type contact binary system with a short period of 0. B, V, Rc and Ic light curves of the eclipsing binary system were obtained by using the 1. By collecting times of minimum light, we studied the orbital period change of VZ Psc.

    A sinusoidal variation was discovered in the O - C diagram, and the amplitude of 0. This can be caused by Applegate mechanism or light-time effect. Both the mechanisms are suited according to our investigation, but we prefer the latter that the light-time effect due to the presence of a third body results in the cyclic variation.

    By using the W-D program, we analyzed the four color light curves. Because of the asymmetric light curves and the possible third body, we used the spot mode of W-D program with and without L3. We found that a hot spot on the primary component with the third light leads to the best result.

    A very high filling factor of This study presents the absolute parameters of the contact binary system V And. The instrumental magnitudes of all observed stars were converted into standard magnitudes. New BV light curves of the system were analysed using the Wilson-Devinney method supplemented with a Monte Carlo type algorithm. Since there are large asymmetries between maxima i. Combining the solutions of our light curves and Rucinski et al. We also discuss the evolution of the system, which appears to have an age of 1.

    Since the dawn of civilization, we have beheld at the beauty and wonder of the natural world around us and wondered how it came to be. We have pondered the past, and have been intrigued about the future. For this we are unique. Our ancestors looked to the vastness of space and thought surely there are others out there.

    We are now at a new time in human history where we can address these age-old questions with a scientific approach and study rigorously the three big questions of astrobiology: Where do we come from? Where are we going? These fundamental questions of astrobiology correspond to those of humanity, and arguably, what makes us human. And so we cannot help but be drawn to the field. Unlike other scientific disciplines, Astrobiology draws on the latest advances in a multitude of fields, from evolutionary and molecular biology, to prebiotic and interstellar chemistry, from astrophysics to astronomy, with a healthy dose of earth and planetary science.

    Astrobiology is in reality a "metadiscipline" drawing on useful science wherever it is to be found. From a practical point of view, this endeavor requires the interaction of scientists who might not normally meet each other, much less work on a common research project. And, unlike most other scientific disciplines, Astrobiology has implications for how we see ourselves, and how we interact with the earth and beyond. Either result will force ethical considerations of either "the other" and their relationship to us, or our solitude and thus responsibility as the only life form in our cosmos. So what is Astrobiology?

    Let's start with the "Where do we come from? But this doesn't address why this happened the way it did without a comprehensive understanding of the environment. What was the temperature at such and such a time? Was the earth in a snowball phase or being bombarded by meteorites -- or even just a single large, well-placed one such as struck off the Yucatan peninsula 65 million years ago. This event could not have been predicted by population genetics alone, yet it had the most profound influence on our evolution as without it, we could still be in a world dominated by dinosaurs with the mammals cowering under cover.

    One must go back to the dawn of life. How did life arise? What was the environmental backdrop that allowed it to happen? How did we happen to end up with a habitable planet? Indeed, what is the origin and evolution of our solar system, galaxy, biogenic elements all the way back to the Big Bang. The "Where are we going? Whereas the past was dominated by physical and chemical processes, and organismal interactions, the future has a new major player: us.

    While we probably don't have the power yet to stop our galaxy passing through another, or even reset the sun or stop the movement of the moon away from the earth, all of these things will influence the future of life on earth. We are already proving that we have the power to visit other bodies in our solar system, either with humans or our robotic surrogates. We are changing our atmospheric composition and thus our climate. We have the power to render species extinct, including our own.

    But we also have the power to use these tools for the common good, to extend our lifetimes and reclaim our rivers and forests.

    Which will it be? And then there is the question where science fiction becomes a reality: "Are we alone? But what if there was a beneficent alien civilization that could communicate with us, perhaps forging a mutual understanding? More likely in the forseeable future is finding a small life, less evolved, life form. Note I did not use the word "simple" as there is nothing "simple" about life, ever. Which brings us back to the question: what is life? So where does Brazil come in? Each time I go to Brazil, I am impressed by the enthusiasm of the community, both scientific and student, the latter an excellent omen for the future of astrobiology in Brazil.

    Facilities are being built to supplement the natural laboratories that Brazil is blessed to have. In my own lab I have been privileged to have a wonderful Brazilian postdoctoral fellow, Dr. Ivan Paulino-Lima, resulting in a daily reminder of the program. I am honored to have been part of the development of astrobiology in Brazil, and hope that this relationship will continue to flourish. Clearly to advance astrobiology needs new knowledge, a reorganization of that which is known, and space missions.

    To help the reader join on this quest, what follows is a buffet of topics that will allow the reader to nibble on the richness that is Astrobiology. And, like a fabulous meal, it should make you want more. Welcome to Astrobiology. We present new photometric observations covering eight minima times for the eclipsing binary GSC Eight minima times were obtained from the new observations. Investigations into the thermal non-equilibrium of W UMa -type contact binaries.

    Traditionally, some physical details e. However, the real evolutionary processes which usually contain several of these physical mechanisms are very complicated as a result of strong interaction between components. To avoid dealing with these factors, a linear relationship is applied to the temperatures of components. On this basis, a variation trend of fill-out factor f changing with mass ratio can be inferred, which is consistent with observations.

    Moreover, if we stick to this point of view, it should be natural that the number of semi-detached binaries in the predicted broken-contact phase of relaxation oscillations is less than the number in the contact phase. A year-old boy presented congenital, raised, yellowish colored plaques with fibroelastic consistency, which were velvety in appearance, alopecic, with clearly defined limits and sulci or well-marked meandering invaginations, a cerebriform appearance on the upper part of the right ear, accompanied by alopecia in the temporomandibular region-parietal.

    The lesion was asymptomatic. Histopathologic examination revealed acanthosis, hyperkeratosis, papillomatosis and follicular plugging in the epidermis. The upper dermis showed underdeveloped hair follicles with sebaceous glands, consistent with sebaceous nevus. There were no skeletal, cardiological, ophthalmological or neuropsychomotor changes; nor were there any records of relevant pathologies in the family history.

    The patient complained of his appearance, experiencing aesthetic and social issues. Following a diagnosis of cerebriform nevus sebaceous, complete excision was performed with excellent aesthetic results. Lava level is a fundamental measure of lava lake activity, but very little continuous long-term data exist worldwide to explore this aspect of lava lake behavior.

    The ongoing summit eruption at Kilauea Volcano began in and is characterized by an active lava lake within the eruptive vent. Lava level has been measured nearly continuously at Kilauea for several years using a combination of webcam images, laser rangefinder, and terrestrial LIDAR.

    Fluctuations in lava level have been a common aspect of the eruption and occur over several timescales. At the shortest timescale, the lava lake level can change over seconds to hours owing to two observed shallow gas-related processes. First, gas pistoning is common and is driven by episodic gas accumulation and release from the surface of the lava lake, causing the lava level to rise and fall by up to 20 m.

    Second, rockfalls into the lake trigger abrupt gas release, and lava level may drop as much as 10 m as a result. Over days, cyclic changes in lava level closely track cycles of deflation-inflation DI deformation events at the summit, leading to level changes up to 50 m. Rift zone intrusions have caused large up to m drops in lava level over several days. On the timescale of weeks to months, the lava level follows the long-term inflation and deflation of the summit region, resulting in level changes up to m. The remarkable correlation between lava level and deflation-inflation cycles, as well as the long-term deformation of the summit region, indicates that the lava lake acts as a reliable 'piezometer' a measure of liquid pressure in the magma plumbing system ; therefore, assessments of summit pressurization and rift zone eruption potential can now be carried out with the naked eye.

    The coupling of these lava levels implies an efficient hydraulic connection between the summit and east rift zone vents. This connection has been indicated previously with geophysical data and is reinforced in a new quantitative manner with lava level data. Lastly, the current lava level at the summit is significantly lower than the mean level measured in the crater during continuous lava lake activity in the early s. The precise correspondence between lava lake level and deformation of the summit implies that the lake level is a good indication of the pressure state of the magma reservoir.

    Tracking lava level over time may therefore provide an indication of the potential for future changes in eruptive activity. Such an observation has clear relevance for monitoring analogous open-vent basaltic volcanoes, especially where other measures of volcanic activity, like seismic or deformation measurements, may be lacking. Splenic artery aneurysm. Splenic artery aneurysms - the most common visceral artery aneurysms - are found most often in multiparous women and in patients with portal hypertension.

    Indications for treatment of splenic artery aneurysm or pseudoaneurysm include specific symptoms, female gender and childbearing age, presence of portal hypertension, planned liver transplantation, a pseudoaneurysm of any size, and an aneurysm with a diameter of more than 2. Historically, the treatment of splenic artery aneurysm has been surgical ligation of the splenic artery, ligation of the aneurysm, or aneurysmectomy with or without splenectomy, depending on the aneurysm location.

    There are other percutaneous interventional techniques. The authors present a case of a splenic artery aneurysm in a year-old woman, detected incidentally. Hypertriglyceridemia: Is there a role for prophylactic apheresis? A case report. Severe hypertriglyceridemia has been consistently associated with an increased risk of cardiovascular disease and other complications, namely acute pancreatitis. Plasma exchange was performed with simultaneous medical treatment to achieve a rapid and effective lowering of triglycerides in order to prevent clinical complications.

    After three plasmapheresis sessions a marked reduction in triglyceride and total cholesterol levels was observed. Several cases have shown the importance of plasmapheresis in the treatment of acute pancreatitis. We intend to demonstrate the applicability of this technique as primary prophylaxis in the presence of extremely high serum triglyceridemia levels. Telephone interventions for adherence to colpocytological examination.

    Todas as mulheres receberam PN de rotina. A critical review of period analyses and implications for mass exchange in W UMa eclipsing binaries: Paper 3. This is the third of a series of four papers, the goal of which is to identify the overcontact eclipsing binary star systems for which a solid case can be made for mass exchange. To reach this goal, it is necessary first to identify those systems for which there is a strong case for period change. We have identified 60 candidate systems; in the first two papers Nelson et al.

    For each system, we present a detailed discussion and evaluation concerning the observational and interpretive material presented in the literature. At least one eclipse timing ET diagram, commonly referred to as an "O-C diagram", that includes the latest available data, accompanies each discussion. In paper 4, we will discuss the mechanisms that can cause period change and which of the 60 systems can be reliably concluded to exhibit mass exchange; we will also provide a list of marginal and rejected cases - suitable for future work.

    Evaluating bronchodilator response in pediatric patients with post-infectious bronchiolitis obliterans: use of different criteria for identifying airway reversibility. Post-infectious bronchiolitis obliterans PIBO is a clinical entity that has been classified as constrictive, fixed obstruction of the lumen by fibrotic tissue.

    However, recent studies using impulse oscillometry have reported bronchodilator responses in PIBO patients. The objective of this study was to evaluate bronchodilator responses in pediatric PIBO patients, comparing different criteria to define the response. We evaluated pediatric patients diagnosed with PIBO and treated at one of two pediatric pulmonology outpatient clinics in the city of Porto Alegre, Brazil.

    Spirometric parameters were measured in accordance with international recommendations. We included a total of 72 pediatric PIBO patients. There were post-bronchodilator improvements. We found that age at viral aggression, a family history of asthma, and allergy had no significant effects on bronchodilator responses.

    Pediatric patients with PIBO have peripheral airway obstruction that is responsive to treatment but is not completely reversible with a bronchodilator. The concept of PIBO as fixed, irreversible obstruction does not seem to apply to this population. Our data suggest that airway obstruction is variable in PIBO patients, a finding that could have major clinical implications.

    Entretanto, estudos recentes utilizando oscilometria de impulso relataram resposta ao broncodilatador em pacientes com BOPI.

The added power of more than two samples is enormous in improving capture-recapture estimates of numbers. A chain. Report No. Memoria No. The first known occurrence of thorite in Portugal is reported.

    The mineral was found as small dark reddishbrown euhedral grains scattered in a soil sample from the hyper-alkaline syerdte region of Alter Pedroso, in prospecting for radioactive materials. Zircon, riebeckite, aegirine, feldspar, biotite, magnetite all of these common minerals of the hyper-alkaline syenite , and a few other urddentified minerals were found in the soil associated with thorite.

    This suggests the weathering of a local pegmatitic differentiation of the syenite as the origin of the thorite. Specific gravity determinations were somewhat impaired by zircon inclusions and led to a value of 4. The chemical composition was determined by emission and x-ray fluorescence spectrography and shows a high yttrium content. X-raypowder patterns obtained before and after heating the sample to ts C for 1 hr in air confirmed the mineral to be only slightly metamict and showed that the tetragonal phase still prevails above ts C.

The sample consisted of 50 women with high-risk pregnancies 25 in the control group and 25 in the intervention group.

    The Benson relaxation technique was applied to the intervention group for five days. Control variables were collected using a predesigned form, and the signs and symptoms of depression were evaluated using the Edinburgh Postnatal Depression Scale EPDS. The Wilcoxon and paired t-tests were used to evaluate depression levels between two timepoints. Using categorical data, the McNemar test was used to analyse differences in depression severity before and after the intervention.

    Noncommunicable diseases and the use of health services: analysis of the National Health Survey in Brazil. To assess whether sex, education level, and health insurance affect the use of health services among the adult Brazilian population with chronic noncommunicable diseases NCD. Frequency of use of services in the population that referred at least one NCD were compared with the frequency from a population that did not report NCD, according to sex, education level, health insurance, and NCD number 1, 2, 3, 4, or more.

    The presence of a noncommunicable disease was associated with increase in hospitalizations in the last 12 months, in 1. Failing to perform usual activities in the last two weeks for health reasons was 3. NCD carriers make more use of health services, as well as women, people with higher number of comorbidities, with health insurance, and higher education level.

Este no es un programa To validate the Pain Assessment Checklist for Seniors with Limited Ability to Communicate - Portuguese in demented elderly and to analyze its measurement properties.

    We evaluated 50 elderly with dementia, residing in a nursing home and with limited communication ability, when exposed to potentially painful situations. The tool was applied at two different moments. First, two interviewers applied it simultaneously, and the intensity of pain was asked based on the caregiver's opinion. After 14 days, with no analgesic intervention, one of the interviewers applied it again. The sample comprised more females, aged over 80 years, with dementia due to Alzheimer, presenting musculoskeletal pain of moderate to severe intensity.

    The psychometric properties of the tool demonstrated appropriate internal consistency Cronbach's alpha coefficient of 0. The scale had excellent reproducibility, according to the intraclass correlation coefficient, and the tool has been duly validated. The Pain Assessment Checklist for Seniors with Limited Ability to Communicate - Portuguese had adequate measuring properties for use with elderly presenting limited communication.
