The strength and ductility of concrete improve under multi-axial compressive stress due to confinement effect. Some parameters are effective for considering the confinement in concrete and various stress-strain models were developed by different researchers. Longitudinal and transverse reinforcement steels can influence on confinement in reinforced concrete members. In this paper, various stres...

Surprisingly little has been published on the subject of which women have their babies at home and which in hospital. It is, therefore, the purpose of this paper to indicate some at least of the factors which are related to the place of confinement. The relative importance of these various factors is shown; and the perinatal mortality rate is considered as a possible means of assessing whether ...

In [Math. Meth. Appl. Sci. 19 (1996) 53-62], C. Marchioro examined the problem of vorticity confinement in the exterior of a smooth bounded domain. The main result in Marchioro’s paper is that solutions of the incompressible 2D Euler equations with compactly supported nonnegative initial vorticity in the exterior of a connected bounded region have vorticity support with diameter growing at most...

It is not unreasonable to expect that boreal forests which exist along 60 o N in the Eurasian and North American continents were created and are maintained by warm seasonal rainfall. As revealed from satellite observations and various precipitation sources, zonally elongated rainbelts appear along these forests. Previous studies show that a relationship may exist between the frontal zone along ...

This article presents findings of a qualitative study reporting older adults’ experiences solitary home confinement during Portugal’s first COVID-19 lockdown in 2020. Home was marked by negative experiences, with the exception one participant who had particularly favorable combination resources and circumstances. Negative involved losses several areas, such as being deprived out-of-home activit...
