Results of an experimental investigation of the seismic performance of prefabricated column-footing connections are presented. Tests were conducted on six 1/4-scale prefabricated column specimens inserted into prefabricated footings in two Groups. Group-1 consisted of four specimens, which were tested under constant axial load and cyclic inelastic lateral displacements. The remaining two specim...

– The Toco Toucan (Ramphastos toco) is a large canopy frugivore common in the seasonal areas of the interior of Brazil. In this study, I evaluated fruit production and analyzed the toucan’s feeding habits in two types of dry forests, one deciduous, although rich in figs, and another semi-deciduous, both in the western Brazil. Both areas exhibited marked fruiting patterns, which peaks overlapped...

The lowland rainforest of northeastern Costa Rica harbours an assemblage of large wandering spider species belonging to three habitat subguilds: (1) semi-aquatic, (2) forest ground dwelling and (3) vegetation dwelling. We hypothesized that desiccation resistance should differ among species preferring different microhabitats and the associated microclimate. Desiccation resistance was assessed by...

In a Riemannian manifold, the existence of a new connection is proved. In particular cases, this connection reduces to several symmetric, semi-symmetric and quarter-symmetric connections; even some of them are not introduced so far. We also find formula for curvature tensor of this new connection. 2000 Mathematics Subject Classification: 53B15.

Water and phosphorus (P) are two critical resources for high nature value farming in semi-dry mountains. ey are major drivers of grassland productivity but can negatively a€ect plant diversity. Soil moisture is known to a€ect soil microbial activity and plant P nutrition but the e€ects of irrigation on soil P status, soil microbial P and plant P nutrition in semi-natural grasslands remain larg...

This paper presents a fully dry assembly method to obtain densely packed arrays of parts from 400-800μm in size. This approach shows promise for enabling formation of a module of n and p type materials optimized for micro scale thermoelectric cooling performance. INTRODUCTION Inertial force (mass of the assembled parts) plays a critical role for part alignment and orienting in a dry microassemb...

The dry forests of northeastern Brazil are found near the coastal zone and on low, isolated mountains inland amid semi-arid vegetation. The floristic composition of these dry montane forests, as well as their relationship to humid forests (Atlantic forest sensu stricto) and to the deciduous thorn woodlands (Caatinga sensu stricto) of the Brazilian northeast are not yet well known. This paper so...

Today connections are playing an important role in the steel frames subjected to lateral seismic loading. The steel extended end-plate moment connection can play an important role in the steel frame when subjected to seismic loadings. In the past, this type of connection has been under investigation mainly when it was subjected to monotonic loading. After major recent earthquakes and failure of...
