Digital soil mapping : bridging research, environmental application, and operation by Janis L Boettinger( )

8 editions published in 2010 in English and held by 18 WorldCat member libraries worldwide

"Digital Soil Mapping" is the creation and the population of a geographically referenced soil database. It is generated at a given resolution by using field and laboratory observation methods coupled with environmental data through quantitative relationships. Digital soil mapping is advancing on different fronts at different rates all across the world. This book presents the state-of-the art and explores strategies for bridging research, production, and environmental application of digital soil mapping. It includes examples from North America, South America, Europe, Asia, and Austral

=A transistor amplifier with 500-mc bandwidth by David W Howell( Book )

2 editions published in 1964 in English and held by 2 WorldCat member libraries worldwide

The design, construction, and evaluation of a lowpass transistor amplifier having 50-db insertion power gain and 500-Mc bandwidth are discussed. The amplifier, useful for i-f, rf, or fast-pulse amplification, consists of seven common-emitter stages, each having collectorto-base feedback. A generalized design procedure is given which should be useful for the con struction of other lowpass amplifiers having bandwidths of 500 Mc or greater. (Author)
A Numerical Study of Rain-Induced Surface Gravity Wave Attenuation by David W Howell( Book )

2 editions published in 1989 in English and held by 2 WorldCat member libraries worldwide

Strong rain-induced mixing in a thin surface layer is numerically shown to greatly increase surface gravity wave attenuation. This case study uses a single wavelength (2.8 m) together with two mixed layer depths (10 and 20 cm). The rain induced mixing is simulated by varying kinematic viscosity within the mixed layer from 0.000001 to 0.01 sq m per sec, molecular to strong turbulent mixing, respectively. The results indicate that surface gravity wave attenuation in the presence of a thin rain induced mixed layer can increase by a factor of up to 6000 times the attenuation rate due to molecular viscosity alone. This indicates that rain need only mix the top 10-20 cm surface layer to effectively dampen short surface gravity waves
