Rapid Method For Determining Fertilizer Nutrients In Liquid Dairy And Swine Manures, Joseph L. Taraba Jan 1988

Rapid Method For Determining Fertilizer Nutrients In Liquid Dairy And Swine Manures, Joseph L. Taraba

Agricultural Engineering Extension Updates

A rapid on-farm determination is needed to assess the fertilizer contents of liquid manure as it is taken from storage. Rapid determination of a tank load for liquid manure will indicate nutrient changes that occur as manure is removed from a storage which cannot be or is not effectively agitated before manure removal. Effective utilization of animal manures as a fertilizer resource requires a farmer to have a knowledge of the amount of nutrients that he is putting onto the soil. If the producer then reduces the commercial fertilizer, he can realize the fertilizer economic value of the manure. Laboratory …

A Bulk Optically Controlled Semiconductor Switch, Rudolf K.F. Germer, Karl H. Schoenbach, Stephen G.E. Pronko Jan 1988

A Bulk Optically Controlled Semiconductor Switch, Rudolf K.F. Germer, Karl H. Schoenbach, Stephen G.E. Pronko

Bioelectrics Publications

Turn‐on and turn‐off of bulk semiconductor switches, based on excitation and quenching of photoconductivity, respectively, have been demonstrated with copper‐doped II‐VI semiconductor crystals. The increase of the conductivity (turn‐on) was realized with a xenon flash‐lamp pulse of 15‐μs duration. A reduction of the conductivity (turn‐off) was obtained by irradiating the samples with IR light using an 8‐ns Nd:YAG laser pulse (YAG denotes yttrium aluminum garnet). For turn‐on in CdS:Cu the conductivity follows the xenon flash excitation. The turn‐off time constant was 250 ns. ZnS and ZnSe crystals showed a slower response. A memory effect for the IR light was observed.

Three-Position Function Generation Of Planar Four-Bar Mechanisms With Equal Deviation Transmission Angle Control, Clark R. Barker, Gwo Huey Shu

Mining Engineering Faculty Research & Creative Works

In an earlier work, it has been shown that all of the potential solutions to a given problem may be represented in an αβ-plane which can be subdivided into mechanism types. Further, the regions in the αβ-plane may represent two possible forms of assembly plus a change of form class which are not valid solutions. In this paper, we provide a third-order polynomial which defines the locus in the αbeta-plane of solutions which have equal deviation of their transmission angle from the ideal of 90° throughout the entire range of motion. When these solutions are mapped into a Cartesian plane, …
