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 features that identify it as juvenile.The dermal tuberositi

Abstract Background The holistic approach of traditional medicine renders the identification of its mechanisms of action difficult.Microarray technology provides an efficient way to analyze the complex genome-wide gene expression of cells treated with mixtures of medicinal ingredients.We performed transcriptional profiling of MCF-7 cells treated wi

The sustained penetration of wind and solar generation is conducive to alleviating the energy crisis and environmental pollution.However, the finite capacity of transmission corridor limits the delivery of remote renewables and leads to curtailment.Energy storage plays an important role in renewables accommodation and improving equipment crystal cu

At the end of the 18th century and at the beginning of the 19th century, observatory saosin baltimore buildings underwent a change, because astronomical tools of observation had transformed from light portable equipment into permanently mounted accurate instruments.For positional astronomy, observations were mainly carried out in the meridian or in

This paper summarizes the results of research aimed at assessing cracks in reinforced concrete structures using embedded ultrasonic sensors.The diffuse ultrasonic waves were considered to evaluate the health status of the tested structures.There are different algorithms used to detect cracks in the structure, but most studies have been performed on
