Using a principal components analysis of morphological data of 1,759 specimens, we detected that the Bothrops neuwiedi complex (with 12 subspecies) is, actually, comprised of 7 full species, differing mainly by qualitative characteristics.One Mattress Pads species was nominal.Five subspecies were elevated to the species level.Bothrops iglesiasi and
The Clinical Use of Vernier Acuity: Resolution of the Visual Cortex Is More Than Meets the Eye
Vernier acuity measures the ability to detect a misalignment or positional offset between visual stimuli, for example between two vertical lines when reading a vernier scale.It is considered a form of visual hyperacuity due to its detectable thresholds being considerably smaller than the diameter of a foveal cone receptor, which limits the spatial
CT scanning and reconstruction of coal samples: principle, method and application
The internal microstructure of coal directly affects the mechanical properties and seepage properties of coal.It is the internal Aluminum Ornament factor that induces coal and gas outburst, water damage, spontaneous combustion and other disasters.It is very important to analyze the microstructure of coal and its interaction with the permeability pr
The burden of vitamin D deficiency in household members of children presenting with symptomatic vitamin D deficiency
BackgroundMicronutrient deficiencies are common among household/family members due to shared lifestyle and dietary habits.The extent of biochemical abnormalities in household members of children presenting with symptomatic vitamin D deficiency remains unknown.AimInvestigate the prevalence of vitamin D deficiency and biochemical osteomalacia in the
