Ammonia (NH3) emission from nitrogen (N) fertilizers used in agriculture decreases N uptake by the crop and negatively impacts air quality. In order to better understand the factors influencing NH3 emission from agriculture, this research was conducted with four major soils used for potato production: Biscayne Marl Soil (BMS, pH 7.27), and Krome Gravelly Loam (KGL, pH 7.69) from Florida; and Qu...

The multi-channel thermal unimolecular decomposition of glyoxal was experimentally investigated in the temperature range 1106 K < T < 2320 K and at total densities of 1.7 x 10(-6) mol cm(-3) < rho < 1.9 x 10(-5) mol cm(-3) by monitoring HCO (frequency modulation spectroscopy, FMS), (CHO)(2) (UV absorption), and H atom (atom resonance absorption spectroscopy, H-ARAS) concentration-time profiles ...

Study of gate length dependent effective velocity manifests the velocity overshoot effects in MOSFETs. Effective velocity of holes in control Si, S i ~ . s G e ~ . ~ and Sio.793Geo,2Co.oo7 devices with different channel lengths are shown in Fig. 2. As channel length decreases, vef increases in every device. In the case of the 0.8 pm device, the effective hole velocity of Sio.793Ge0.2C0.007 is e...

case report about pneumacephalus after influenza virus infection, a topic that may be underestimated in its incidence. Delayed pneumocephalus represents a rare but well-reported complication of cerebrospinal fluid (CSF) diversion diseases that may be also the origin of the disease in the presented case. The exact pathophysiology of the development of pneumocephalus after influenza virus infecti...

A recently introduced formulation of time dependent linear response density functional theory within the plane-wave pseudopotential framework @J. Hutter, J. Chem. Phys. 118, 3928 ~2003!# is applied to the study of solvent shift and intensity enhancement effects of the A2 n→p* electronic transition in acetone, treating solute and solvent at the same level of theory. We propose a suitable formali...
