Los saurios y anfisbénidos de Bolivia (Reptilia, Squamata): lista patrón, localidades y bibliografía

The number of Bolivian lizards and amphisbaenids is increased from 79 (Fugler, 1989) to 102 in this updated and comprehensive list, which includes all new species and taxonomic changes published recently, as well as locality data. Coordinates for the localities are provided in a locality list. Three species are reported herein for the first time: Kentropyx pelviceps, Liolaemus schmidti, and Uranoscodon superciliosus.El número de saurios y anfisbénidos conocidos en Bolivia se incrementa de 79 especies (Fugler, 1989) a 102 en la presente lista actualizada, que incorpora todas las especies nuevas, los cambios taxonómicos recientes y todas las localidades de colecta conocidas con sus coordenadas. Tres especies son citadas para Bolivia por primera vez en este trabajo: Kentropyx pelviceps, Liolaemus schmidti y Uranoscodon superciliosus

Primera cita de Leptodactylus ocellatus (Linnaeus, 1758) (Amphibia, Anura, Leptodactylidae) en Bolivia y comentarios sobre especies próximas

The distributions of Leptodactylus ocellatus, L. chaquensis, and L. macrosternum in Bolivia are reviewed and discussed. Leptodactylus chaquensis and L. ocellatus are easily distinguished morphologically but L. chaquensis and L. macrosternum are indistinguishable. In Bolivia, L. ocellatus is known only from a single locality in the Paraguay River basin, which is reported here for the first time. Leptodactylus chaquensis occurs in the Chaco region of southeastern Bolivia, but it is unknown to what extent this species enters the Cerrado. The distribution boundaries and putative overlapping areas of L. chaquensis and L. macrosternum are unknown.Se revisa y discute la distribución de Leptodactylus ocellatus, L. chaquensis y L. macrosternum en Bolivia. Mientras que, morfológicamente, L. chaquensis y L. ocellatus se diferencian fácilmente, L. chaquensis y L. macrosternum son imposibles de distinguir. Leptodactylus ocellatus se encuentra en la parte boliviana de la cuenca del río Paraguay, aunque de momento se conoce solamente de una localidad, que se cita aquí por primera vez. Leptodactylus chaquensis habita en el Chaco, pero se deconoce hasta dónde penetra en el Cerrado. No se conocen los límites de las áreas de distribución y posibles zonas de solapamiento de L. chaquensis y L. macrosternum

Edge States and Topological Pumping in Stiffness Modulated Elastic Plates

We demonstrate that modulations of the stiffness properties of an elastic plate along a spatial dimension induce edge states spanning non-trivial gaps characterized by integer valued Chern numbers. We also show that topological pumping is induced by smooth variations of the phase of the modulation profile along one spatial dimension, which results in adiabatic edge-to-edge transitions of the edge states. The concept is first illustrated numerically for sinusoidal stiffness modulations, and then experimentally demonstrated in a plate with square-wave thickness profile. The presented numerical and experimental results show how continuous modulations of properties may be exploited in the quest for topological phases of matter. This opens new possibilities for topology-based waveguiding through slow modulations along a second dimension, spatial or temporal

Sensitivity Analysis and Quantification of the Role of Governing Transport Mechanisms and Parameters in a Gas Flow Model for Low-Permeability Porous Media

Recent models represent gas (methane) migration in low-permeability media as a weighted sum of various contributions, each associated with a given flow regime. These models typically embed numerous chemical/physical parameters that cannot be easily and unambiguously evaluated via experimental investigations. In this context, modern sensitivity analysis techniques enable us to diagnose the behavior of a given model through the quantification of the importance and role of model input uncertainties with respect to a target model output. Here, we rely on two global sensitivity analysis approaches and metrics (i.e., variance-based Sobol’ indices and moment-based AMA indices) to assess the behavior of a recent interpretive model that conceptualizes gas migration as the sum of a surface diffusion mechanism and two weighted bulk flow components. We quantitatively investigate the impact of (i) each uncertain model parameter and (ii) the type of their associated probability distribution on the evaluation of methane flow. We then derive the structure of an effective diffusion coefficient embedding all complex mechanisms of the model considered and allowing quantification of the relative contribution of each flow mechanism to the overall gas flow

Efficacy and safety of trabeculectomy vs nonpenetrating surgical procedures: a systematic review and meta-analysis

To date, only a few studies have directly compared nonpenetrating surgery (NPS) and trabeculectomy (TE). Therefore, there is no strong evidence as to which surgical technique leads to the best results in terms of ocular hypotensive effect and safety

Analisis Faktor yang Mempengaruhi Pendapatan Petani Padi Pengguna Pupuk Organik dan Anorganik di Kecamatan Harau

Penelitian ini dilatar belakangi oleh adanya ketergantungan petani menggunakan pupuk anorganik dan meningkatnya harga pupuk anorganik tersebut yang berakibat pada bertambahnya biaya produksi dan berkurangnya keuntungan USAhatani padi, sehingga berpengaruh terhadap kesejahteraan keluarga petani. Berdasarkan penelitian sebelumnya diperoleh informasi bahwa terdapat perbedaan pendapatan petani padi pengguna pupuk organik dengan pendapatan petani padi pengguna pupuk anorganik di Kecamatan Harau. Oleh karena itu, tujuan dari penelitian ini adalah untuk menganalisis faktor-faktor yang mempengaruhi pendapatan petani padi pengguna pupuk organik dan anorganik di Kecamatan Harau. Penelitian ini dilakukan dengan menggunakan survey kepada petani padi di Kecamatan Harau. Analisa data dilakukan secara kuantitatif yaitu melalui analisa regresi linier berganda dan dilanjutkan dengan uji F. Berdasarkan hasil penelitian diketahui bahwa faktor yang  mempengaruhi  secara  nyata  pendapatan  petani  padi pengguna pupuk organik dan anorganik  di  Kecamatan  Harau adalah: Luas lahan dan biaya produksi. Sedangkan faktor  yang mempengaruhi secara tidak nyata adalah: umur petani, pendidikan petani, jumlah produksi dan harga produksi
