aAs a result nanowire density decreases as temperature increases, as seen in the sequence of SEM images of Figure 5. The oxide grains become larger as temperature increases in our experiment. Although we have tried to raise the heating temperature to 800°C, large oxide grains are observed, bu...
Plasma column density fluctuation spectra observed from the Buaro ionospheric barium release have been analyzed as a function of altitude over the range 285 km to 345 km. The wavenumber spectra become steeper with increasing altitude, the first time this has been shown in any ionospheric injection...
As altitude increases and the atmosphere thins more solar ultraviolet-B (UV-B) radiation (280–315 nm) reaches the surface (Frohnmeyer and Staiger, 2003). High-altitude vineyards in Mendoza, Argentina, receive higher levels of erythemally weighted UV-B irradiance than those at lower altitudes ...
The most frequent insects on flowers of a given weed are not necessarily the most efficient pollinators. Indeed, the efficiency of insects as pollinators, especially bees, depends on many factors concerning pollen transport and deposit, such as the particular morphology of the insect body parts (...
but its effectiveness in limiting or extinguishing combustion depends upon the density of the wood [132,133]. Furthermore, the development of cracks in the char layer increases the rate of penetration of heat into the pyrolysis zone [134]. Oxidative erosion of the char layer can also occur if...

(near superior solar conjunctions), the Sun is located between Mercury and the Earth, and the mean level of noise increases from <0.5 m for 90° < SPE < 180° to ~1.5 m for 35° < SPE < 90° (Fig.1). MESSENGER orbits close to superior solar conjunctions (...
In addi- tion to improving strength and bone mineral density, whole body vibration (WBV) improves peripheral circulation[159, 160] and increases lymph flow, raising the threshold level for edema formation in the legs[161]. During WBV, the user simply stands (or stretches/exercises) on a...
Answer to: In general, the vapor pressure of a substance increases as ___ increases. a. surface tension b. molecular weight c. hydrogen bonding d...
While the 10–30 cm root biomass and the 0–10 cm coarser central root biomass were calculated per volume (all roots sampled per given volume), the 0–10 cm finer root biomass was calculated based on a root:soil weight ratio in combination with soil bulk density. We chose that...
