Cypris metamorphosis was followed using video microscopy in four species of cirripeds representing the suspension-feeding pedunculated and sessile Thoracica and the parasitic Rhizocephala. Cirripede metamorphosis involves one or more highly complex molts that mark the change from a free cypris larva to an attached suspension feeder (Thoracica) or an endoparasite (Rhizocephala). The cyprids and ...

Suillus quiescens sp. nov. is common under Pinus muricata on Santa Cruz and Santa Rosa Islands in the northern Channel Islands of California, and we subsequently found it fruiting at Point Reyes National Seashore on the central coast of California. Sequences from the internal transcribed spacer region show that it is distinct from all 44 species of Suillus tested, and features of its morphology...

ROSA is a Learning Object (LO) repository system with semantic access, which enables the management of LOs. LO is a collection of reusable material used to support learning, characterized by a set of metadata descriptors. LOs are accessed in a contextualized way, determined by semantic associations between them. This paper presents ROSA+, a system extension that aims at deducing additional sema...

Rosa centifolia and Rosa gruss an teplitz distillation waste biomass was immobilized using sodium alginate for Pb(II) uptake from aqueous solutions under varied experimental conditions. The maximum Pb(II) adsorption occurred at pH 5. Immobilized rose waste biomasses were modified physically and chemically to enhance Pb(II) removal. The Langmuir sorption isotherm and pseudo-second-order kinetic ...

Transgenic overexpression of the Notch1 intracellular domain inhibits osteoblast differentiation and causes osteopenia, and inactivation of Notch1 and Notch2 increases bone volume transiently and induces osteoblastic differentiation. However, the biology of Notch is cell-context-dependent, and consequences of Notch activation in cells of the osteoblastic lineage at various stages of differentia...

Apoptosis is one way of controlling immune responses, and a variety of immunosuppressive drugs suppress harmful immune responses by inducing apoptosis of lymphocytes. In this study we observed that rosmarinic acid, a secondary metabolite of herbal plants, induced apoptosis in an p56(lck) (Lck)-dependent manner; Lck(+) Jurkat T cells undergo apoptosis in response to rosmarinic acid (RosA) treatm...

Nature of Work: ‘Santa Rosa’ magnolia, a selection of the native Magnolia virginiana L. (Sweet Bay magnolia) introduced by Woodlanders Nursery, Aiken, S.C. in 1979, is an upright, evergreen tree with an open growth habit. Leaves of ‘Santa Rosa’ are larger than the species as are the lemon scented flowers (Raulston, personal communication). These attributes along with height growth that approach...

ROSA is an e-learning system, which enables the management of Learning Objects (LOs). However, since ROSA is a centralized system, it does not provide a complete integration of LOs created in local ROSAs of other institutions. This paper presents the evolution of ROSA into a peer-to-peer (P2P) system the ROSA P2P, and describes the integration process of LOs in this environment. It provides the...
