OBJECTIVE The oblique fissure separates the upper lobe from the lower lobe in the left lung and the upper lobe from the lower and middle lobes in the right lung. The aim of the present study was to compare the projection of the oblique fissure observed on lateral chest radiographs of retired coal mine workers who had coal worker's pneumoconiosis (CWP) with that of healthy men. MATERIALS AND M...

The sluicing flume that was designed is less capable of silting up and losing its calibration than its counterparts of standard sharp-crested compound weir design. The laboratory work described here led to a refinement in the design in the form of a short flume set into the lowest section of a compound Crump weir gauging installation. Critical flow occurs near the exit of this flume, and it is ...

Abstract—This study investigated the change of weir structure performances when durability of concrete, which is the main material of weir structure, decreased due to their aging by mean of seismic fragility analysis. In the analysis, it was assumed that the elastic modulus of concrete was reduced by 10% in order to account for their aged deterioration. Additionally, the analysis of seismic fra...

Nowadays, developed and applied hydrology become very important thing in the life due to the wide verity advantages for the applications of this field. Hydraulic Structures such as crump weir are placed in channels to estimate or measure flow rate and flow control devices. In this study there is a new performance for crump weir which appears by adding opening holes in the model  of crump weir. ...

Our ability to align three Gabor patches depends upon their internal carrier orientation; we are better at aligning vertical or horizontal patches than oblique patches (Keeble and Hess, 1998). However, the tuning of alignment to patch orientation has not studied in detail. We measured the alignment of a vertical target with reference patches varying in orientation and found it tuned to vertical...
