Island restoration to rebuild seabird populations and amplify coral reef functioning
Abstract Mobile organisms like seabirds can provide important nutrient flows between ecosystems, but this connectivity has been interrupted by the degradation of island ecosystems. Island restoration (via invasive species eradications and the restoration of native vegetation) can reestablish seabird populations and their nutrient transfers between ...

Abstract Conservation translocations are an important conservation tool commonly employed to augment declining or reestablish extirpated populations. One goal of augmentation is to increase genetic diversity and reduce the risk of inbreeding depression (i.e., genetic rescue).

A Comparative study of solidification of Al-Cu alloy under flow of cylindrical radial heat and the unidirectional vertically [PDF]
A pesar de la importancia tecnológica de la solidificación de aleaciones metálicas bajo flujo de calor radial, se han realizado relativamente pocos estudios en esta área. En este trabajo se analiza la solidificación de cilindros de Al 4,5% en peso de Cu contra un molde macizo de acero y se compara con la solidificación unidireccional contra un molde ...

Abstract Private land protection is an important and growing tool to address biodiversity loss and climate change. Thus, better empirical evidence on the effectiveness of private land protection and organizational practices, such as targeting of lands for protection and choice of protection mechanism (i.e., fee simple land acquisition and conservation ...

Models for wellhead protection in regional unconfined aquifers and stratified aquifers
En este trabajo son presentados los conceptos matemáticos usados para el desarrollo de la protección de cabezales de pozos y la metodología de zonificación. Ellos están basados en soluciones analíticas, en el flujo del agua subterránea y en la modelación

Load Flow Analysis and the Impact of a Solar PV Generator in a Radial Distribution Network
The distribution system acts as a conduit between the consumer and the bulk power grid. Due to characteristics such as a high resistance/reactance ratio, distribution networks cannot be solved using conventional methods, such as the Gauss-Seidel and Newton–Raphson. This research proposes a method for the calculation of the power flow in radial networks

Normalmente, en una formación heterogénea, el periodo de transición del flujo fracturasmatriz toma lugar durante el flujo radial. Sin embargo, dependiendo del valor del parámetro de flujo interporoso, dicha transición puede ocurrir antes o después del ...

Many well pressure data coming from long and narrow reservoirs which result from either fluvial deposition of faulting cannot be completely interpreted by conventional analysis since some flow regimes are not conventionally recognized yet in the oil ...
