This study investigated the wind pressure characteristics of an elliptical plan retractable dome roof. Wind tunnel experiments were performed on roofs with varying wall height-to-span ratios (0.1–0.5) and opening (0, 10, 30, 50 %), where ratio was defined as open area roof to total The resulting peak coefficients closed then compared those Japanese load code (AIJ-RLB (2015)) there are no curren...

Let be a commutative ring with 1 and left unitary . In this paper, the generalizations for notions of compressible module retractable are given. An is termed to semi-essentially if can embedded in every non-zero semi-essential submodules. module, submodule an Some their advantages characterizations examples We also study relation between these classes some other modules.

The soil water retention curve (SWRC) relates moisture to energy (matrix potential). calculation of the volumetrichumidity considers sample volume. In retractable soils, this volume varies according drying or wetting soil, which can result in errors calculated moisture. objective study is quantify variation soils and elaborate SWRC via traditional method, does not consider retraction, a second ...
