Technology Development Outsourcing: When to Join Forces With a Rival?

Journal of Operations Management, EarlyView.
ABSTRACT Knowing the challenges of collaborating with a competitor in developing new technologies, firms sometimes still choose a competitor instead of a noncompeting technology provider. To explore why, this study adopts an inter‐organizational trust view to explain the formation of a technology development outsourcing relationship.

Influence of Seabed Scouring on the Bearing Capacity of Suction Caisson Foundations of Offshore Wind Turbines

Journal of Marine Science and Engineering
Local scour around suction caisson foundations has emerged as a significant geotechnical hazard for offshore wind turbines as developments extend into deeper waters.

Scour due to turbulent wall jets downstream of low-/high-head hydraulic structures

Cogent Engineering, 2016
To overcome over-prediction of the scour depths by existing methods, a mathematical model is developed based on a work transfer theory. This model predicts the equilibrium scour hole’s depth and length due to two-dimensional turbulent wall jets ...

Biofilm removal capacity and titanium surface integrity in non‐abrasive versus abrasive peri‐implantitis cleaning interventions

Journal of Periodontology, EarlyView.
Abstract Background Current peri‐implantitis treatment methods are modeled after dental cleaning modalities like abrasive surface cleaning. However, mechanical abrasive cleaning not only inadequately removes implant biofilms but also compromises implant surface integrity with adverse biological effects.

Experimental investigation of scour downstream of a type A trapezoidal piano key weir under free and submerged flow conditions

Journal of Hydrology and Hydromechanics
In this paper, the scour downstream of a trapezoidal Piano key weir (PKW) is investigated under free and submerged flow conditions. For this purpose, an experimental model was used in a laboratory channel with a length of 10 m, width of 0.75 m, and ...

Holocene sea‐level and environmental changes on the Isle of Mull, Scotland

Journal of Quaternary Science, EarlyView.
ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

Investigating the scour at piers of successive bridges with debris accumulation

Journal of Infrastructure Preservation and Resilience
Bridge scour around piers and abutments poses a significant threat to bridge stability, particularly in dynamic river environments like the Tigris River in Baghdad.

Dog attacks on wild desert tortoises: A risk model

The Journal of Wildlife Management, EarlyView.
Domestic dogs attack and severely injure wild desert tortoises at the urban and ex‐urban interface with deserts. Severe trauma to tortoises increased 4 times to shell and limbs and 16.5 times to the gular horn over the decades between the 1970s and 2000s. Tortoises were at exponential risk of severe trauma when living within 12 km of settlements, towns,

Wild pig habitat use impacted by prescribed fire in the William B. Bankhead National Forest, USA

The Journal of Wildlife Management, EarlyView.
Natural resource management activities like integrated wild pig control programs and 3–5‐year interval prescribed burning can reduce wild pig activity and habitat but can have an unintended side effect of allowing them to thrive in sensitive and protected areas, where access and tools are restricted.

Estimation of scour depth at a single non-submerged vertical spur dike under unidirectional currents

Water Science and Engineering
Accurately estimating equilibrium scour depths at spur dikes remains challenging due to the complexity of scour around these structures. Scour critically threatens spur dikes built in river estuaries for enhancing navigability and preventing bank erosion.
