ECOLOGY AND CAUDAL SKELETAL MORPHOLOGY IN BIRDS: THE CONVERGENT EVOLUTION OF PYGOSTYLE SHAPE IN UNDERWATER FORAGING TAXA.

Ecology and caudal skeletal morphology in birds: the convergent evolution of pygostyle shape in underwater foraging taxa.

Birds exhibit a specialized tail that serves as an integral part of the flight apparatus, supplementing the role of the wings in facilitating high performance aerial locomotion.The evolution of this function for the tail contributed to the diversification of birds by allowing them to utilize a wider range of flight behaviors and thus exploit a grea

Renormalisation group equations for BRST-restored chiral theory in dimensional renormalisation: application to two-loop chiral-QED

Abstract We discuss how renormalisation group equations can be consistently formulated using the algebraic renormalisation framework, in the context of a dimensionally-renormalised chiral field theory in the BMHV scheme, Face Primer where the BRST symmetry, originally broken at the quantum level, is restored via finite counterterms.We compare it wi

Changes in ventilatory mechanics caused by variations in PEEP and pressure support: study in healthy subjects under non-invasive mechanical ventilation

Introduction: Traditionally, ventilatory Beast Machines mechanics has been delivered in controlled modes through the use of inappropriate approaches for spontaneous ventilation.Objective: To measure the changes of ventilatory mechanics caused by PEEP and pressure support (PS) variations in non-invasive mechanical ventilation.Materials and methods:

Ten simple rules for socially responsible science.

Guidelines concerning the potentially harmful effects of scientific Makeup Box With LED Mirror studies have historically focused on ethical considerations for minimizing risk for participants.However, studies can also indirectly inflict harm on individuals and social groups through how they are designed, reported, and disseminated.As evidenced by r
