ONTOGENETIC CHANGE IN THE TEMPORAL REGION OF THE EARLY PERMIAN PARAREPTILE DELORHYNCHUS CIFELLII AND THE IMPLICATIONS FOR CLOSURE OF THE TEMPORAL FENESTRA IN AMNIOTES.

A juvenile specimen of Delorhynchus cifellii, collected from the Early Permian fissure-fill deposits of Richards Spur, Oklahoma, permits the first detailed study of cranial ontogeny in this parareptile.The specimen, consisting of a partially articulated skull and mandible, exhibits several Steering Column features that identify it as juvenile.The d

The natural limits of capitalism are expressed not only in the global suspension of economic growth, which has been considered endless.It is also a crisis of its non-economic legitimization, of those political forms that have made possible smoothing of inequality generated by capitalism.The nation-state, the model of social state and representative

Nanotechnology is associated with the development of particles in the nano-size range that can be used in a wide range of applications in the medical field.It has gained more importance in the pharmaceutical research field particularly in drug delivery, as it results in enhanced therapeutic drug performance, improved drug solubility, targeted drug

Oversampling analog-to-digital converters (ADC) serve as the backbone of high-performance, high-precision data interfaces, owing to their remarkable ability to filter out quantization noise.This attribute makes them the preferred choice for applications requiring high signal-to-noise ratio (SNR) and moderate bandwidth, with great design flexibility
