This study presents the results of large scale laboratory model tests to investigate the behavior of Compacted Lime – Well-graded Soil (CL-WS) rigid stone columns in soft soils. The  unit cell idealization is used for construction of composite specimens by evaluating the influence of different parameters such as the diameter of the column (D), the slenderness ratio (L/D) and the area ratio (Ar)...

rural tourism is considered as one of the important parts of the economic activities. this important economic activity in the different views has been taken into consideration. some know it as a part of the tourism market and some consider it as a policy for rural development. rural tourism quickly grew in the rural economic and has been the complementary of agricultural activities. the nature ...

Stereoscopic vision is extremely precise in detecting minute diierences between adjacent depth planes, but quite imprecise in estimating absolute depth. In this paper, we address the issue of the spatial acuity (and not the stereo acuity) of stereopsis. Static RDS (random dot stereograms) stimuli were used to nd the spatial grain in which human stereoscopic vision operates. Using psychophysical...

Automatic hydraulic press is widely used for pressing ceramic wall and floor tiles, the four columns of its frame withstand the all work force when it works, so the columns are the key compartments of the frame, and its work performance has an important impact on the structural performance of the entire automatic hydraulic press. Took the column thread connection of 32.8MN automatic hydraulic p...

Abstract Unlike older design codes, Eurocode 2 does not provide a procedure for calculation of the capacity axially loaded columns. For that purpose, general algorithm is developed, using principles structural mechanics and mathematics: It starts with constructing P-Δ relationship (buckling curve) element, accounting initial imperfections, minimum eccentricity, material nonlinearity second orde...

DESCRIPTION A 39-year-old man presented with a 5-day history of increasing left eye swelling and erythema, after a palm tree branch struck his face.

PURPOSE The intraorbital wooden foreign body is often misdiagnosed or missed on computed tomog- raphy (CT) scan, due to the invisible or unclear images. The residual foreign bodies often occur during surgical removal. The clinical manifestations, imaging features and treatment of intraorbital wooden foreign bodies were discussed in this study. METHOD We retrospectively analyzed 14 cases of in...
