Late middle Triassic to early Late Triassic insects from Argentina have been previously described from the Bermejo and Cuyana Basins where they have been recovered from the Ischichuca-Los Rastros and Potrerillos-Cacheuta Formations, respectively. The insect fauna discussed herein was collected during field studies in 1986/1987 from the Llantenes section （Norian to Rhaetian？ Late Triassic）, which is situated in the malargiie Basin in southern mendoza province. The insect remains were found in the upper part of the Llantenes section （Llantenes Formation）, which is built up of two coarsening-upwards cycles reflecting a deltaic progradation of a fluvial into a lacustrine environment （lower part）, succeeded by repeated progradatious into a floodplaindominated environment （upper part; with finds of insects, conchostracans, fish remains, plant fragments, and drifted logs）. The new finds represent the youngest Triassic insect records described from Argentina and even from South America in its entirety. There is only one contemporaneous fossil assemblage in Gondwana： in the Ciarence/moreton Basin （Aberdare Conglomerate; Late Norian） in Australia. The new Triassic insects include an impression of an isolated mecopterida-like wing （mendozachorista volkheimeri gen. et sp. nov.; mendozachoristidae fam. nov.）, coleopteran elytra of the Permosynidae （Ademosyne rosenfeldi sp. nov. and Ademosyne Uantenesensis sp. nov.） and other isolated body fragments. This new Late Triassic entomofauna from Argentina is of considerable importance in the reconstruction of the biotic recovery of continental environments in Gondwana after the catastrophic mass extinction at the P/T boundary.

Low-cost disordered carbons for Li/S batteries： A high- performance carbon with dual porosity derived from cherry pits

Nano Research 2018年第1期11卷 89-100页

A micro- and mesoporous carbon obtained from cherry pit waste and activated with HBPO4 acid has been studied as the sulfur host for Li/S batteries. The carbon has a high specific surface area of 1,662 m2·g-1 （SBET） and micropore and mesopore volumes of 0.57 and 0.40 cm3·g-1, respectively. The S/C composite, with a sulfur content of 57% deposited by the disproportionate reaction of a SaO2- solution in an acid medium without an additional heating step above the S melting point, delivers an initial specific capacity of 1,148 mah·g-1 at a current of C/16. It also has a high capacity retention of 915 mAh·g-1 after 100 cycles and a Coulombic efficiency close to 100%. The good performance of the composite was also observed under higher current rates and long-term cycling tests. The capacities delivered by the cell after 200 cycles were 707 and 410 mAh·g-1 at C/2 and 1C （1C = 1,675 mA·g-1）, respectively, maintaining the high Coulombic efficiency. The overall electrochemical response of this carbon as the sulfur matrix is among the best reported so far among the other biomass-derived carbons, probably because of the micro- and mesopore system formed upon activation.

Hydrodynamic Study of Lake Enriquillo in Dominican Republic

Journal of Geoscience and Environment Protection 2017年第5期5卷 115-124页

作者： A. Delanoy Ramón rafael méndez-Tejeda Facultad de Ciencias Instituto de Física Universidad Autónoma de Santo Domingo Santo Domingo Dominican Republic Laboratorio de Ciencias Atmosféricas Departamento de Ciencias Naturales Universidad de Puerto Rico en Carolina Carolina Puerto Rico

This study presents an analysis of the hydrochemical characteristics of Lake Enriquillo in the southwestern region of the Dominican Republic. This lake is hypersaline and endorheic. The climatology of the region is influenced by the Caribbean Regulator Climate Centers (CRCCs). Due to the endorheic nature of the basin, evaporation plays an extremely important role in its dynamics [1]. During the study period, in November 2002, the water level of Lake Enriquillo was 42 m below sea level (BLS), and the salinity level was 104.2‰. By 2014, the water level of the lake rose to 29 m below sea level, and the salinity decreased to 23.4‰, as a result of the high cyclonic activity in the Caribbean region.

Perceptions of Climate Change in Puerto Rico before and after Hurricane maria

American Journal of Climate Change 2021年第2期10卷 153-166页

作者： méndez-Tejeda rafael maría Santos-Corrada mena Sandra Natural Science Department Atmospherical Science Laboratory University of Puerto Rico at Carolina Puerto Rico USA School of Business and Entrepreneurship University of Ana G. Méndez Gurabo Puerto Rico USA

This article analyzes the perceptions of Puerto Rican citizens of global climate change (GCC) before and after an extreme weather event, specifically Hurricane maria (Hm). The purpose of the current article is to evaluate Puerto Ricans’ perceptions of the impact of extreme meteorological phenomena and of GCC before and after Hm. This tropical cyclone entered the island as a category IV hurricane on September 17, 2017, causing enormous destruction, loss of life, and economic damage. In this study, two data samples were collected before and after Hm struck Puerto Rico (PR) (the second sample was collected approximately six months after the hurricane). Surveyed citizens with general knowledge of GCC increased from 43% to 62%, which the researchers consider a small increase, considering the severe destruction caused by Hm. This study also found that Puerto Ricans trust non-profit institutions and the scientific community more than state authorities. Furthermore, 85% of citizens believe that public policies on GCC should be directed by the state (federal, state, and municipal governments);this did not change after Hm. In addition, this study found that the poor response of the federal and state governments to the destruction caused by Hm increased citizens’ trust in the scientific community.

Three-dimensional mapping and comparative analysis of the distal human corpus cavernosum and the inflatable penile prosthesis

引用

Asian Journal of Andrology 2013年第4期15卷 567-570,I0012页

作者： Tariq S Hakky Daniel Ferguson Philippe E Spiess Paul Bradley Tom FLue rafael E Carrion Department of Urology University of South Florida Tampa General Circle Tampa FL 33602 USA 23D3Solutions Burnaby BCV5J 5M8 Canada and Department of Urology University of Southern California San Francisco 400 Parnassus Ave San Francisco CA 94143 USA

The intricate anatomy of the corpus cavernosum in both the flaccid and tumescent state has not been fully elucidated. We report our experience using a three-dimensional （3D） scanner to reconstruct cadaveric casts and compare them with 3D images of two prototypes of penile prosthesis. Two different models of the Titan Coloplast inflatable penile prosthesis were analyzed using a 3D scanner. The first was the standard model and the second was a newer model with a rounder silicone tip. Two cadaveric phalluses were harvested using Smooth-Cast 300Q polyurethane molding. The molds were excised and scanned along side the penile prosthesis. 3D scans were completed and analyzed using Leios mesh software, and GOm Inspect software. The 3D scans demonstrated the mean human corporal radii 2 mm from the distal tip to be 36.51 mm （36.01-37.0 mm）, which is an obtuse angle. The standard Titan penile prosthesis spherical radius at the same level was 202.52 mm, while the new silicone tip prosthesis had a radius of 139.33 mm. 3D mapping further demonstrated the trajectory of the cavernosa appeared curvilinear and the distal ends appeared blunt. The use of cadaveric cavernosal molds in combination with the 3D scanner allowed us to accurately image the corpus cavernosum for the first time. Our findings suggest that anatomically accurate corporal tips appear to be relatively blunt and that the new Titan silicone tip penile prosthesis more closely resembles the human corporal tip.
