THE QUANTIFICATION OF MORPHOLOGICAL VARIATION AND DEVELOPMENT OF MORPHOLOGY-BASED KEYS TO IDENTIFY SPECIES OF FUSCONAIA AND PLEUROBEMA (UNIONIDAE) IN THE GREEN RIVER, KENTUCKY, USA

We quantified morphological variation among genetically identified specimens of Fusconaia flava, F.subrotunda, Pleurobema cordatum, P.plenum, P.sintoxia, and P.rubrum inhabiting the Green River, Kentucky, species with shells that are morphologically similar to each other and thus difficult to identify.Molecular identifications then were compared wi

BACKGROUND AND HYPOTHESES:This study is the first to offer an in-depth comparison of elimination testing with the scoring rule of Arnold & Arnold (hereafter referred to as elimination testing with adapted scoring) and negative marking.As such, this study is motivated by the search for an alternative for negative marking that still discourages guess

Buckling restrained braces (BRBs) which are generally composed of a steel core and a encasing(buckling restrainers) are utilized to resist lateral forces in high seismic regions since BRBs exhibit high energy dissipation capacity, ductility and stiffness.The steel core carries both compressive and tensile forces.During the compression, the core sta

Swiss Federalism builds on the traditional and to a certain extent also themodern diversities.Since middle age the Swiss confederation has always beenenriched and challenged by economic, religious, collegiate graduate saddle cultural and linguistic diversities.Since the foundation of Switzerland as a state of modernity in 1848the constitution has b

Background: We established that the age at inception of T1DM significantly impacts the long-term risk of developing proliferative retinopathy in affected children and adolescents.Patients with T1DM, diagnosed before the age of 15 are at a significantly higher risk than children diagnosed at age 15 and older.For instance, several studies show change
