Local Scour at the Elliptical Guide Banks
Scour development in time at the elliptical guide banks during the floods was studied. The dimensions of the upper part of the elliptical guide banks, namely the turn and length, were calculated by the Latishenko method.

Niche occupancy of Jamaican bat caves: Diversity increases isotopic niche packing
Journal of Animal Ecology, EarlyView.Tropical bat caves are home to hundreds of thousands of bats of multiple species. In Jamaica, we found that isotopic niche packing is the likely mechanism of coexistence at more diverse sites. Abstract There are over 1000 documented caves across Jamaica, many of them used by diverse communities of bats.

علوم آب و خاک, 2018 The investigation of local scour below hydraulic structures is so complex that makes it difficult to establish a general model to provide an accurate estimation for the local scour dimension.

Journal of the Royal Anthropological Institute, EarlyView.Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Scour, Local and Critical Velocities at the Abutments on Plain Rivers
Local flow modification near engineering structures such as – local velocity, flow separation, circulation, vortex structures, and increased turbulence, leads to local scour near foundations.

Gender &History, EarlyView.ABSTRACT The article examines what cleanliness, that is, hygiene and tidiness, meant for landowning farm households in the county of Härjedalen in the inland of northern Sweden from the 1860s to the 1910s. The period is characterised by a growing understanding of bacteria and of how infectious diseases could be prevented through improved hygiene ...

Local Scour at Elliptical Guide Banks in Plain Rivers
The scour development in floods at abutments (Gjunsburgs & Neilands 2001, 2004, 2005, Gjunsburgs et al. 2004, 2005, 2006) and at elliptical guide banks is studied. The scour hole extents at abutments and guide banks are different. At the upstream head of

History, EarlyView.Abstract This article examines an overlooked attempt to colonize the island of Trinidad during the English Revolution of the 1640s. This project was engineered by a consortium of radical puritans, seeking to create a protected enclave in the New World for separatists, anabaptists and other sectaries.

Riverbed Layering Impact on Scour at the Abutments
The damage of the engineering structures caused by scour leads to considerable economical and envi-ronmental losses. The local flow modification and its changes in time during the floods, as well as local geological conditions, as riverbed layering, type
