CT scan is the best method in the diagnosis of paranasal sinus diseases. The object of the present study was to show the efficiency of diagnostic endoscopy in diagnosing nasal paranasal sinus diseases and anomalies. If this method proves to be accurate, patients who refuse surgery can be diagnosed, managed and followed up through a reliable method that is cost-effective and de...

Introduction: This study aimed to investigate the relationship between the prevalence of dental anomalies and hypodontia. Materials and Methods: In this retrospective study, the panoramic radiographs of 101 cases with tooth agenesis (except for the third molar) were studied and compared with [Pn1] those of a non-agenesis control group of 182 subjects. The subjects were within the age range of ...

objective the associations between imperforate anus and spinal and vertebral abnormalities and neurologic deficits are well recognized; these neurologic deficits have been considered static rather than progressive. however, recent experience indicates that some patients may develop progressive neurologic problems due to spinal cord lesions that are amenable to neurosurgical correction. material...

The response of atmospheric blocks and the wave amplitude of midlatitude jets to changes in the midlatitude to pole, near-surface temperature difference (ΔT), is studied using an idealized dry general circulation model (GCM) with Held-Suarez forcing. Decreasing ΔT results in slower zonal winds, a mean state with reduced meridional gradient of the 500 hPa geopotential height (Z500), a smaller va...

Investigations of the anomalies in the Earth rotation, in particular, the polar motion components, play an important role in our understanding of the processes that drive changes in the Earth’s surface, interior, atmosphere, and ocean. This paper is primarily aimed at investigation of the Chandler wobble (CW) at the whole available 163-year interval to search for the major CW amplitude and phas...

The potential of high-temperature (>150°C) geothermal systems in crustal fault zones (fault cores and hundreds meters wide networks interconnected fractures the damage zone) is underestimated. Based on numerical models, we show that topography-driven, poroelasticity-driven as well buoyancy-driven forces play a significant role establishment shallow (1–4 km) thermal anomalies zones. We investiga...

An effective method of identifying and discriminating undersaturated gas accumulations remains unresolved, resulting in uncertainty hydrocarbon exploration. To address this problem, an unsupervised machine learning multi-attribute analysis is performed on 3D post-stack seismic data over several blocks within the deepwater Gulf Mexico Carnarvon Basin, offshore Australia. Results reveal that low-...
