Journal of Ultrasound in Medicine, EarlyView.Chorionic villus sampling (CVS) is a crucial prenatal diagnostic tool, but a declining number of procedures makes training a challenge. Here we describe a transcervical CVS simulator made from ballistic gelatin. Ninety‐three Maternal‐Fetal Medicine providers used the simulators during hands‐on workshops and completed surveys regarding their fidelity ...

Moose indifferent to canopy loss from forest disturbance by bark beetles
The Journal of Wildlife Management, EarlyView.Moose showed strikingly similar patterns of habitat selection before and after widespread forest disturbance following an infestation of bark beetles. Our findings indicate that beetle‐kill does not appreciably alter habitat quality for moose and highlight the importance of riparian areas in sustaining moose as they contend with changing forests ...

A Comparison of Timber Models for Use in Public Policy Analysis [PDF]
In this paper, we compare and contrast two types of timber models that have been used for public policy analysis. These models have been variously used to predict price, inventory and market welfare impacts under different exogenous forces that impact ...

When their population increases excessively, they can weaken the trees and cause their death. In México, federal regulations obligate forest landowners to carry out sanitary logging to control bark beetle outbreaks in adherence to official procedures.

Silviculture in African moist forests : do we have new answers to old questions? [PDF]
, 2011 The silviculture of African tropical moist forests has a long history punctuated with (few) successes and (many) failures. The European foresters in charge of managing forests in the African colonies realized early - e.g. 1900 in Nigeria - that they were

Land Degradation &Development, EarlyView.ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.

Steel-to-Timber and Timber-to-Timber Simple Shear Connections
WSEAS TRANSACTIONS ON APPLIED AND THEORETICAL MECHANICSThe main objective of this manuscript is to present an analytical procedure of steel-to-timber and timber-to-timber connections in simple shear, related to the calculated number of dowels needed. These types of connections need to be assembled by dowel–type fasteners, such as nails, screws, bolts, and dowels.

Land Degradation &Development, EarlyView.ABSTRACT Forest ecosystem services (ESs) are garnering increasing public attention as awareness grows regarding society's fundamental dependence on them for well‐being. Forest fires, one of the major disturbances of ESs, are becoming more frequent and destructive, exacerbated in part by climate change.
