Abstract

The purpose of this study was to compare the values of university students as a function of socio-demographic variables such as: gender, ,kind of school (religious vs.non-religious; private vs. public), religion (Catholic - Non Catholic) and age. A self-administered scale of 55 values was designed for this research and it was used with a sample of 3.384 students selected intentionally.. The values scale showed five dimensions: Cosmopolitan, Social, Instrumental, Moral and Conservative. Results indicated that women presented a higher appreciation of Moral, Social and Conservative values, whereas men valued more the Cosmopolitan values. The students that attended religious schools valued more the Conservative dimension. The socio demographic variable of major influence in the axiological preferences was gender and the value dimension differentiated by most socio-demographic factors was the Conservative

Abstract

Optical sensors and sensing technologies are playing a more and more important role in our modern world. From micro-probes to large devices used in such diverse areas like medical diagnosis, defence, monitoring of industrial and environmental conditions, optics can be used in a variety of ways to achieve compact, low cost, stand-off sensing with extreme sensitivity and selectivity. Actually, the challenges to the design and functioning of an optical sensor for a particular application requires intimate knowledge of the optical, material, and environmental properties that can affect its performance. This roadmap on optical sensors addresses different technologies and application areas. It is constituted by twelve contributions authored by world-leading experts, providing insight into the current state-of-the-art and the challenges their respective fields face. Two articles address the area of optical fibre sensors, encompassing both conventional and specialty optical fibres. Several other articles are dedicated to laser-based sensors, micro- and nano-engineered sensors, whispering-gallery mode and plasmonic sensors. The use of optical sensors in chemical, biological and biomedical areas is discussed in some other papers. Different approaches required to satisfy applications at visible, infrared and THz spectral regions are also discussed.

14. Assessment of a high-resolution central scheme for the solution of the relativistic hydrodynamics equations

Subjects

Abstract

We assess the suitability of a recent high-resolution central scheme developed by Kurganov & Tadmor (2000) for the solution of the relativistic hydrodynamics equations. The novelty of this approach relies on the absence of Riemann solvers in the solution procedure. The computations we present are performed in one and two spatial dimensions in Minkowski spacetime. Standard numerical experiments such as shock tubes and the relativistic flat-faced step test are performed. As an astrophysical application the article includes two-dimensional simulations of the propagation of relativistic jets using both Cartesian and cylindrical coordinates. The simulations reported clearly show the capabilities of the numerical scheme to yield satisfactory results, with an accuracy comparable to that obtained by the so-called high-resolution shock-capturing schemes based upon Riemann solvers (Godunov-type schemes), even well inside the ultrarelativistic regime. Such central scheme can be straightforwardly applied to hyperbolic systems of conservation laws for which the characteristic structure is not explicitly known, or in cases where the exact solution of the Riemann problem is prohibitively expensive to compute numerically. Finally, we present comparisons with results obtained using various Godunov-type schemes as well as with those obtained using other high-resolution central schemes which have recently been reported in the literature., Comment: 14 pages, 12 figures, to appear in A&A

Abstract

Demographic studies are crucial for assessment of the status of dolphin populations and their relationship with anthropogenic activities as a way to make effective management and conservation decisions. In the Gulf of Mexico, the interaction between bottlenose dolphins (Tursiops truncatus) and anthropogenic activities merits special attention. The objective of this study was therefore to determine the annual abundance and area of preference of the coastal population of T. truncatus (period 2005–2020), and to delimit a priority area for its conservation in the Southern Gulf of Mexico marine ecoregion.Abundance was calculated using the Jolly–Seber model and habitat preference was determined per climatic season (dry, rainy and cold northerly fronts) as a function of environmental variables. The association between anthropogenic activities and dolphin distribution was studied and the priority area delimited using potential distribution models.Off the coasts of Tuxpan and Tamiahua, the results show that the dolphin population numbered 306 individuals (95% CI: 162.97; 607.33) and has remained relatively constant over time.The pattern of dolphin distribution varied between seasons, possibly owing to changes in food availability. However, river mouths and lagoons are of importance to T. truncatus throughout the year. On the other hand, fishing and maritime traffic can potentially affect this species.Finally, this study shows that the delimitation of sites of importance for T. truncatus is a strategic tool with which to help conserve the species and associated coastal ecosystems.

Abstract

Puma yagouaroundi is a feline with a wide distribution in America and little known in its ecology and habitat use. The present note reports its presence in peri-urban areas in Tuxpan, Veracruz, Mexico. In addition, the record of one road-killed animal in a nearby area demonstrates the tolerance of this species to disturbed sites, as well as its susceptibility to mortality in communication ways, relevant information that can be applied at programs for its conservation considering that it is a threatened species in Mexico., Puma yagouaroundi es un felino de amplia distribución en América y poco conocido en su ecología y uso de hábitat, por lo que la presente nota documenta su presencia en sitios periurbanas en Tuxpan, Veracruz, México. Además, el registro de un animal atropellado en una zona cercana demuestra la tolerancia de esta especie a sitios perturbados, así como su susceptibilidad por la mortandad en vías de comunicación, información que puede ser relevante para aplicar programas para su conservación considerando que es una especie amenazada en México.

Abstract

Population structure of Avicennia germinanstrees (Acanthaceae) in a disturbed mangrove in the Gulf of Mexico. Introduction:Globally, mangroves are declining; characterizing their structure and regeneration at different disturbance levels can help understand their responses to stressful situations. Objective:The study's primary goal was to analyze the mangrove community structure and to estimate the populations' trajectories of Avicenia germinansat different mangrove sites that present three levels of disturbance. Methods:Eight transects of approximately 500 m in length and laid perpendicular to the Tamapamchoco lagoon, Veracruz, intersected three levels of disturbance currently present on the mangrove forest. On each transect, 10 x 10 m, 5 x 5 m, and 1 x 1 m quadrants served to account for all mangrove trees by species and stage of maturity in 2017 and 2018. Results:The most abundant species was: A. germinansfollowed by Rhizophora mangleand Laguncularia racemosa. Based on their abundance, we found significant differences for the three levels of disturbance (ANOSIM R = 0.6, P < 0.001) presented in a non-metric ordination (nMDS). A life table for A. germinansallowed a population analysis that showed an intrinsic rate of population increase (r) that was negative at the disturbed sites (-0.0027 and -0.0774) and positive (0.0289) at the apparently undisturbed site. Seedling to juvenile stage survival ranged from 50 % at the undisturbed site to 5 and 4 % at the disturbed sites. Conclusions:Measures to increase the survival of seedlings are necessary to reverse the decreasing population trajectories at the disturbed sites; otherwise, the mangrove will have reduced viability in the medium term. Introducción:Los manglares están en declive en el mundo, conocer su estructura y regeneración en diferentes niveles de alteración puede ayudar a comprender la dinámica poblacional ante situaciones de estrés. Objetivo:La meta principal del estudio fue analizar la estructura comunitaria y estimar la trayectoria de las poblaciones de Avicenia germinansen diferentes sitios de manglar que presentan tres niveles de alteración. Métodos:Ocho transectos de aproximadamente 500 m de largo y colocados de manera perpendicular a la laguna de Tampamachoco, Veracruz, interceptaron tres niveles de alteración en los sitios estudiados del bosque de manglar. En cada transecto, cuadrantes de 10 x 10 m, 5 x 5 m, y 1 x 1 m sirvieron para contar todos los árboles de mangle por especie y estadio de madurez en 2017 y 2018. Resultados:La especie más abundante fue: A. germinansseguida de Rhizophora mangley Laguncularia racemosa. Con base en su abundancia, se encontraron diferencias significativas según los tres grados de alteración (AM R = 0.6, P < 0.001), ilustrado en un análisis de ordenación no métrico (nMDS). Una tabla de vida para A. germinanspermitió un análisis poblacional que mostró una tasa intrínseca de incremento poblacional (r) negativa para los sitios que presentan alteración (-0.0027 u -0.0774) y positiva (0.0289) en el sitio sin alteración aparente. La supervivencia del estadio de plántula a juvenil varia de 50 % en el sitio no alterados a 5 y 4 % en los otros dos sitios. Conclusiones:Se necesitan medidas para incrementar la sobrevivencia de las plántulas y revertir la disminución de las trayectorias en los sitios con alteración, de otra forma el manglar tendrá una viabilidad reducida en el término medio. Palabras Clave: fragmentación; perturbación; tablas de vida; dinámica poblacional; categorías de tamaño.

Abstract

Xenobalanus globicipitis is a commensal barnacle located on cetacean fin edges. The commensal-host interaction between Xenobalanus globicipitis and the bottlenose dolphin (Tursiops truncatus) has been poorly studied in Mexico. The main objective was to estimate the relative barnacle prevalence and abundance in bottlenose dolphins in three areas and seasons of the Gulf of Mexico. Tamiahua zone showed the higher prevalence (42.4%) and relative abundance (0.60 barnacles/individual/hr-1) compared to Tuxpan and Nautla zones. Whereas, in dry season there were higher prevalence (55.6%) and relative abundance (0.53 barnacles/individual/hr-1) than rainy and winter storm seasons. Therefore, zones and seasons of the Gulf of Mexico influence the barnacle-dolphin interactions.

Abstract

Objective: To establish the association between initial and residual angulation of the distal interphalangeal joint (DIJ) in mallet finger treated conservatively. Methods: An observational, prospective, descriptive and analytical research developed with uncomplicated closed mallet finger patients between January and December 2017. A total of two measurements of the DIJ were done, at the initial trauma and 6 weeks after conservative treatment. All measurements were ranked according to the Crawford Classification and Relative Risk was measured. Results: In total, 43 patients were studied, in which 53.48% of outcomes obtained were excellent. The sample was divided in two groups; one with less than 30º of DIJ initial angulation, which had 28% of residual angulation. The second group with more than 30º presented 72.22% of residual angulation. The Relative Risk to present a residual angulation in patients that had 30º of DIJ initial angulation was 2.99 (CI 95%) with p = 0.0059. Conclusion: It is suggested that patients with an initial DIJ angulation more than 30º are more likely to present residual angulation with conservative treatment. Level of Evidence IV, Case series. RESUMO Objetivo: Estabelecer a associação entre a angulação inicial e residual da articulação interfalângica distal em casos de dedo em martelo tratados de forma conservadora. Métodos: Estudo observacional, prospectivo, descritivo e analítico desenvolvido com pacientes que apresentavam dedo em martelo fechado, sem complicações, no período de janeiro a dezembro de 2017. Foram realizadas duas medidas na articulação interfalângica distal, no trauma inicial e seis semanas após o tratamento conservador. Todos foram classificados de acordo com a Classificação Crawford e o Risco Relativo (RR) foi calculado. Resultados: Foram estudados 43 pacientes, dos quais 53,48% apresentaram resultados excelentes. A amostra foi dividida em dois grupos: um com < 30º de angulação interfalângica distal inicial, com 28% de angulação residual, e outro com > 30º, apresentando 72,22% de angulação residual. O risco relativo de apresentar angulação residual em pacientes com 30º de angulação inicial da articulação interfalângica distal foi de 2,99 (IC 95%) com um valor de p = 0,0059. Conclusão: Sugere-se que os pacientes com angulação inicial da articulação interfalângica distal superior a 30º têm maior probabilidade de apresentar angulação residual com tratamento conservador.

49. Population Analysis of The Snapper Lutjanus Griseus, Based on The Artisanal Fisheries of The Tamiahua Coast, Veracruz

Abstract

Artisanal fishery in the Gulf of Mexico is mainly undertaken for subsistence and is, thus, of great socioeconomic importance, with Lutjanidae one of the most important families caught in the region. However, there is scarce fisheries knowledge in the Gulf of Mexico and, in light of pressure from the fishing community, research into the population dynamics of these species is of vital importance for the management or conservation of coastal resources. This study aims to contribute information for the analysis of the population of Lutjanus griseus (Linnaeus, 1758), a common species on the Tamiahua coast, in the state of Veracruz. Samples and biometric data (weight, sex, total length and maturity) were recorded by the fishing community on this coast. The monthly population structure was constructed using fish size. Data from 987 individuals, the size of which oscillated from 15 to 80 cm, were registered over the course of a year. The sex ratio was 1:1, while the maximum calculated age was 10 years. Von Bertalanffy and Gompertz growth models reported a maximum age and growth of L∞=182.46 K= 0.05 and to = -1.71. The best fit was achieved by means of the Gompertz model, as based on the Akaike criteria and the biological interpretation of the parameters. Reported data and the models used in this study suggest that the minimum catch size should be 40 cm and that the fishery should either cease activities in the months of the reproductive peak or that quotas should be among the fishing cooperatives on the coast of Tamiahua.
