The potential influence of genome‐wide adaptive divergence on conservation translocation outcome in an isolated greater sage‐grouse population

open access: yesConservation Biology, Volume 38, Issue 4, August 2024.
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).

Ultrasound-guided radial artery cannulation: A report of a simple and low-cost model for training

open access: yesEducación Médica, 2023
Introduction: Practicing models for invasive procedure have proven useful in achieving better rates of success for physicians in training. Often, these models are not easy to get because of its expensive price.

Estudio del flujo meridional en turbomáquinas axiales [PDF]

open access: yes, 2004
En este trabajo se presenta un estudio numérico del flujo meridional en turbomáquinas axiales. Para ello se ha implementado un código numérico que resuelve el flujo meridional tanto a partir de las ecuaciones de equilibrio radial simplificado, como ...

Understanding variation in impacts from private protected areas across regions and protection mechanisms to inform organizational practices

open access: yesConservation Biology, Volume 38, Issue 2, April 2024.
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 ...

A Comparative study of solidification of Al-Cu alloy under flow of cylindrical radial heat and the unidirectional vertically [PDF]

open access: yesActa Scientiarum. Technology, 2014
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 ...

Load Flow Analysis and the Impact of a Solar PV Generator in a Radial Distribution Network

open access: yesEngineering, Technology & Applied Science Research, 2023
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

A COMPLEMENTARY CONVENTIONAL ANALYSIS FOR CHANNELIZED RESERVOIRS Análisis convencional complementario para yacimientos alagados

open access: yesCT&F Ciencia, Tecnología & Futuro, 2007
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 ...

Eficacia y seguridad del acceso transradial en el intervencionismo coronario percutáneo de oclusiones totales crónicas

open access: yesREC: Interventional Cardiology, 2021
Sr. Editor: El acceso transradial se ha generalizado en el intervencionismo coronario percutáneo (ICP), aunque el tratamiento percutáneo de oclusiones totales crónicas (OTC) sigue realizándose predominantemente por vía transfemoral.

PRESSURE AND PRESSURE DERIVATIVE ANALYSIS FOR LONG NATURALLY FRACTURED RESERVOIRS USING THE TDS TECHNIQUE

open access: yesDyna, 2010
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 ...
