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

Dyna, 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 ...

Gene Flow and Vertical Stratification of Pollination in the Bat‐Pollinated Liana Marcgravia longifolia

Ecology and Evolution, Volume 15, Issue 8, August 2025.
This study investigates pollen dispersal, vertical stratification of gene flow, and spatial genetic structure in the bat‐pollinated liana Marcgravia longifolia in a western Amazonian forest. Flowers are produced from the forest floor to the canopy, allowing analysis of pollination across strata.

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

CT&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 ...

Putting Out Fires With Institutional Reforms: Experts as Policy Entrepreneurs in the Swedish Fire and Rescue Policy Sector, 1986–2021

European Policy Analysis, Volume 11, Issue 3, Page 420-432, Summer 2025.
ABSTRACT This article examines the fire and rescue services sector in Sweden in the period 1986–2021, and explains the timing of bureaucratic reforms using the Multiple Streams Framework (MSF). In this study, we insert institutions in MSF by employing a two‐level analysis; we highlight the interactions among experts acting as policy entrepreneurs over ...

STRAIGHT-LINE CONVENTIONAL TRANSIENT RATE ANALYSIS FOR LONG HOMOGENEOUS AND HETEROGENEOUS RESERVOIRS

Dyna, 2012
El flujo lineal es un régimen de flujo muy importante que se presenta en pozos fracturados, horizontales y yacimientos alargados. Tanto el análisis de pruebas de presión como de transitorio de caudal podrán verse afectados por la presencia del flujo ...

Vitamin D deficiency induces erectile dysfunction: Role of superoxide and Slpi

British Journal of Pharmacology, Volume 182, Issue 15, Page 3669-3687, August 2025.
Background and Purpose Epidemiological studies suggest a relationship between vitamin D deficiency and erectile dysfunction (ED). We hypothesized that vitamin D deficiency or vitamin D receptor (VDR) knockout causes ED and analysed the underlying molecular mechanisms.

PRESSURE AND PRESSURE DERIVATIVE TRANSIENT ANALYSIS WITHOUT TYPE-CURVE MATCHING FOR ELONGATED RESERVOIRS WITH CHANGES IN FACIES OR WIDTH

CT&F Ciencia, Tecnología & Futuro, 2010
Due to geologic and tectonic events many reservoirs have an elongated geometry in which dual-linear and single-linear flow regimes may be developed.

The role of socialization network to understand the adoption of demand‐reduction behaviors: The red siskin's breeders community case study

Conservation Science and Practice, Volume 7, Issue 8, August 2025.
Social network analysis and decision‐making models revealed how socialization networks and psychosocial factors influence the adoption of sustainable bird‐sourcing practices among red siskin breeders across Venezuela, Brazil, Spain, and Portugal. Key findings, such as the role of information flow and attitudes towards collaboration, highlight the ...
