We present the results of optical spectroscopic identifications of a bright subsample of 2–10 keV hard X-ray selected sources from the ASCA Medium Sensitivity Survey in the northern sky (AMSSn). The flux limit of the subsample

In this research, the foliar uptake patterns of three toxic metals (Pb, Cd, and Cu) bound to airborne particulate matter (PM) were investigated using two evergreen tree species (Senna siamea Alstonia scholaris) at six different locations (two residential, traffic, commercial, industrial) plus one control site in a subtropical urban environment. The concentrations Pb, Cu measured from dust, leaf...

a new type of backbone robot is presented in this paper. the core idea is to use a cross shape mechanism with the principle of functioning of the scissors linkages, known as a pantograph. although this continuum arm acts quite similar to tendon-driven robot, this manipulator does not include any tendon in its structure. this design does not suffer from the weaknesses of the continuum design suc...

Induction and synchronous machines have traditionally been the first choice of automotive manufacturers for electric/hybrid vehicles. However, these conventional machines are not able anymore to meet the increasing demands for a higher energy density due to space limitation in cars. Fluxswitching PM (FSPM) machines with their high energy density are very suitable to answer this demand. In this ...

BACKGROUND Physical activity (PA) is widely acknowledged to be beneficial to health and wellbeing, and is potentially influenced by a variety of environmental factors such as ambient temperature, weather conditions and air pollution levels. Since these factors vary seasonally, physical activity participation may also respond seasonally. Current population studies to profile physical activity of...

Canonical Wnt/β-catenin (Wnt) signaling plays multiple conserved roles during fate specification of cardiac progenitors in developing vertebrate embryos. Although lineage analysis in ascidians and mice has indicated there is a close relationship between the cardiac second heart field (SHF) and pharyngeal muscle (PM) progenitors, the signals underlying directional fate decisions of the cells wit...

We present the results of a BeppoSAX observation of the fastest pulsar known: PSR B1937+21. The ∼ 200 ks observation (78.5 (34) ks MECS (LECS) exposure times) allowed us to investigate with high statistical significance both the spectral properties and the pulse profile shape. The absorbed power law spectral model gave a photon index of ∼ 1.7 and N H ∼ 2.3 × 10 22 cm −2. These values explain bo...
