Introduction: Cosmic spherules and micrometeor-ites account for the major fraction of extraterrestrial material accreting on the Earth. The amount of mi-crometeorites arrived on the terrestrial surface is up to 16000 ton [1], which is around 10 times as much as that of meteorites. The JARE-39 expedition recovered great amounts of micrometeorites from Kuwagata and Tottuki areas in Antarctica in ...

Stenohaline freshwater stingrays (Potamotrygon spp.) are endemic to the very dilute (Na(+), Cl(-), Ca2(+) <or=30 micromol L(-1)), often acidic blackwaters of the Rio Negro despite gill Na(+) and Cl(-) transport characteristics that appear unfavorable (high K(m), low J(max)). We evaluated the possible protective role of blackwater itself, which is rich in dissolved organic carbon (DOC), as well ...

Dynamics and control of flexible robot manipulators have received wider attention during the last two decades. In manufacturing and space applications, the use of lightweight structures in robot manipulators is motivated by their capacity for high speed maneuvers, their high payload to arm weight ratio, higher mobility, reduced energy consumption, and lower inertia forces for accurate positioni...

The properties of the neutral pion in quark matter under influence an external magnetic field are studied. effects anomalous moments (AMM) quarks at finite density is considered. inclusion AMM into NJL model gives rise to additional effects. In particular Dirac sea produce new divergences vacuum contributions, which depend explicitly on field. An improper treatment these contributions source un...

This study investigated the association between nutritional intake and indices of muscle mass or strength in 104 female Japanese university students who participated sports activities during their junior senior high school periods had a current physical activity level (PAL). Body composition was measured by bioelectrical impedance method, appendicular (AMM) skeletal index (SMI) were evaluated a...

BACKGROUND AND OBJECTIVES Previous retrospective studies have indicated markedly increased bone marrow angiogenesis (BMA) in myelofibrosis with myeloid metaplasia (MMM). This issue is further examined in the current prospective study and clinico-pathological correlates sought. DESIGN AND METHODS This was a prospective single institutional study of 66 patients with bone marrow biopsy-proven MM...

There has been a long-standing controversy whether information in neuronal networks is carried by the firing rate code or by the firing temporal code. The current status of the rivalry between the two codes is briefly reviewed with the recent studies such as the brain-machine interface (BMI). Then we have proposed a generalized rate model based on the finite N-unit Langevin model subjected to a...

We examined the effect of diesel exhaust particle (DEP) extracts on oral tolerance in mice. For this examination, a single DEP sample was consecutively extracted with hexane (HEX-DEP), benzene (BEN-DEP), dichloromethane (DIC-DEP), methanol (MET-DEP), and 1 M ammonia (AMM-DEP). Residues unextracted (UNE-DEP) with the last extraction solvent 1 M ammonia were also used to test their ability to ind...

In this research, we propose and design an acoustic metamuffler (AMM) by coupling a microperforated plate composite waveguide formed main Helmholtz resonator. The proposed mechanism deliberately designed structure are conducive to generating multimode resonances that help improve the absorption effect lead broadband (4 octaves) sound insulation. We develop effective circuit model analytically p...
