Living on the edge: Habitat characteristics of northern myotis at the periphery of its distribution

The Journal of Wildlife Management, EarlyView.
Northern myotis selected tall trees with minimal decay, in patches with other roosting options. In our study area, these trees occurred in narrow bands within an agricultural matrix, differing from contiguous forest at the core of the species' distribution. Nevertheless, bats selected the tallest trees in the densest patches available.

Posterolateral corner reconstruction using hamstrings grafts—A comparative biomechanical study of three techniques

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare three posterolateral corner (PLC) reconstruction techniques—the popliteofibular loop (PFLoop), the modified LaPrade (LP) and modified Arciero (AR) techniques—in restoring knee laxity in varus (VR), external tibial rotation (ER) and posterior tibial translation (PTT). Methods Nine cadaveric knees were subjected to 8Nm VR, 5Nm

Corrosion Behavior of Magnesium Alloys in Alkaline Solutions Simulating a Low‐Level Radioactive Waste Repository

Materials and Corrosion, EarlyView.
The corrosion rates of two types of magnesium alloys in an alkaline solution containing crushed ordinary Portland cement paste grains decreased with increasing immersion time. This decrease was attributed to the formation of a protective layer containing brucite and hydrotalcite on the specimen surfaces.
