Radiography; Profit or Loss
The use of radiographic images in dentistry to diagnose caries and other dental diseases has always been inevitable. Almost half of all dental caries are diagnosed only by radiography. However, given the benefits of this method for diagnosing the disease, X-ray examinations have undeniable risks for the patient due to the use of ionizing radiation and their improper use increases the risk of th...

In the randomized clinical trial 200 pregnant women reffred to Niknafs maternity center from November 1997 to May 1998 were divided into two groups and underwent cesarean section.in the first group (control) the parietal and visceral peritoneum were approximated with delayed absorbable material whereas in the second group (case) the parietal and visceral peritoneum were left open.the mean age o...
متن کاملQuantum friction–fact or fiction?
Two parallel dielectric plates separated by vacuum interact through zero-point charge fluctuations and experience friction when the plates are in relative motion and the vacuum is sheared. Even at the absolute zero of temperature, residual quantum fluctuations remain because the zero-point energy gives rise to ‘quantum friction’. In a recent paper, the reality of these fluctuations is questione...
متن کاملICOMOS – IFLA Principles Concerning Rural Landscapes as Heritage – Delhi 2017
Rural landscapes are a vital component of the heritage of humanity that contain a complex lattice of tangible and intangible cultural heritage and have a strong connection with their surrounding nature and environment. As a result, they can be named the rural landscapes. Since the living rural landscapes are one of the most common types of cultural landscapes in existence, their conservation is...
متن کاملBorder forces and friction control epithelial closure dynamics.
We study the closure dynamics of a large number of well-controlled circular apertures within an epithelial monolayer, where the collective cell migration responsible for epithelization is triggered by the removal of a spatial constraint rather than by scratching. Based on experimental observations, we propose a physical model that takes into account border forces, friction with the substrate, a...
