Nanoparticles (NPs) are defi ned as ultrafi ne particles with one dimension between 1–100 nm [1]. Because of their small size, they have a very large surface area relative to their weight, so they often react quite differently from a bulk solid or dissolved material of the same composition. For this reason they may offer novel and interesting properties for a broad range of applications. Curren...

we discuss here an uncommon condition of neurogenic hypotension in the context of immunoglobulin light chain (amyloid light-chain) amyloidosis. th e most serious feature was autonomic nervous system impairment, mainly characterized by severe refractory orthostatic hypotension, which became progressively invalidating, forcing the patient to bed. moreover, since the systemic involvement of the di...

exp(2 i( p 1 i ) are the eigenvalues of the Milnor monodromy and their integral part is determined by the Hodge ltration of the mixed Hodge structure. This notion was rst introduced by Steenbrink [11]. By [14] the exponents are constant under -constant deformation of f . In particular, they depend only on f 1 (0). They express the vanishing order (up to the shift by one) of the period integrals...

A recent approach to solve Richards' equation is further improved. This approach brings understanding into the physical processes of in®ltration and ponding. In particular we apply it to analyze the standard hydrologic tool of Time Compression Approximation (TCA). We also suggest that the new approach provides a more reliable alternative to TCA, e.g. for predicting ponding time. Ó 1999 Elsevier...

Acute disseminated encephalomyelitis (ADEM) is a monophasic, postinfectious or postvaccineal acute infl ammatory demyelinating disorder of central nervous system (CNS).[1,2] The pathophysiology involves transient autoimmune response directed at myelin or other self-antigens, possibly by molecular mimicry or by nonspecifi c activation of autoreactive T-cell clones.[3] Histologically, ADEM is cha...

The coronary capillary ow is analyzed theoretically based on continuum mechanics. The capillary is a long, elastic and permeable vessel loaded externally by tissue pressure. It is subject to possible periodic length changes, together with adjacent myocites. Capillary ow is driven by arteriolar-venular pressure di erence. Ultra ltration, due to transmural hydrostatic and osmotic gradients is inc...

2108 Th e eff ect of cell preparation methods on the surface chemistry and retention of Escherichia coli D21 g was investigated over a range of ionic strength conditions. Th e cell preparation methods that were considered included fi ltration and centrifugation (at various speeds and for diff erent durations). For a given ionic strength condition, it was found that cells prepared by fi ltration...

BACKGROUND Micro RNAs (miRNAs) are a pivotal part of non-protein-coding endogenous small RNA molecules that regulate the genes involved in plant growth and development, and respond to biotic and abiotic environmental stresses posttranscriptionally. OBJECTIVE In the present study, we report the results of a systemic search for identification of new miRNAs in B. rapa using homology-based ESTs (...

Developing robust and ecient numerical solution methods for Richards' equation (RE) continues to be a challenge for certain problems. We consider such a problem here: in®ltration into unsaturated porous media initially at static conditions for uniform and non-uniform pore size media. For ponded boundary conditions, a sharp in®ltration front results, which propagates through the media. We evalu...
