BACKGROUND Focal ground-glass opacity (GGO) on thin-section computed tomography (CT) may be seen in atypical adenomatous hyperplasia (AAH), adenocarcinoma in situ that has recently been renamed from bronchioloalveolar carcinoma (BAC) and various benign conditions. CASE PRESENTATION We report a case of pulmonary focal fibrosis associated with microscopic arterio-venous fistula (AVF), which sho...

Figure 1: Stator Cross-Section Figure 1 shows a cartoon view of an axial cross-section of a twelve-slot stator. Actually, what is shown is the shape of a thin sheet of steel, or lamination that is used to make up the magnetic circuit. The iron is made of thin sheets to control eddy current losses. Thickness varies according to freuqency of operation, but in machines for 60 Hz (the vast bulk of ...

Changes in the volume covered by mucin-secreting goblet cell regions within colon thin sections may serve as a means to differentiate between ulcerative colitis and infectious colitis. Here we show that rapid, quantum cascade laser-based mid-infrared microspectroscopy might be able to contribute to the differential diagnosis of colitis ulcerosa, an inflammatory bowel disease. Infrared hyperspec...

In this research, totally 610.4 meters of the Asmari Formation are studied in two stratigraphic sections on Bavan Mountain an Sarvestan section in Fars province, Iran. The indexed microfacies are carefully determined through studying of 230 thin sections.This research shows that the indexed microfacies are mudstone, wackestone, packstone, prainstone and the amount of microfacies elements such a...

The secondary pulmonary lobule is a fundamental unit of lung structure, and it reproduces the lung in miniature. Airways, pulmonary arteries, veins, lymphatics, and the lung interstitium are all represented at the level of the secondary lobule. Several of these components of the secondary lobule are normally visible on thin-section computed tomographic (CT) scans of the lung. The recognition of...

Part of the work in finding petroleum areas consists of interpreting thin section taken from the sample rocks. Geologists uses many techniques to identifying the rock constituents, but one of the most efficient method relies on recognizing the visual pattern of the thin section using a microscope. This image recognition is a complex task that requires a lot of training. In this paper, we presen...
