In in vitro true dry matter degradability (IVTDMD), in situ dry matter degradability, and neutral detergent fiber degradability, both in vitro (IVNDFD) and in situ (ISNDFD) techniques were used with crossbred goats to determine dry matter and neutral detergent fiber (NDF) ruminal degradability in eight forages and four industrial byproducts. Total digestible nutrients (TDN) content obtained wit...

The ability to degrade aromatic amines and m-toluate (Tdn+ phenotype), encoded by plasmid pTDN1, was lost from Pseudomonas putida hosts after subculture in benzoate, succinate, acetate and glucose minimal medium, the fastest rate of loss occurring where benzoate was the substrate. Tdn- cells had either lost the entire pTDN1 plasmid or suffered a recombinational deletion of a specific 26 kbp reg...

Nitrate, ammonium, total dissolved nitrogen (TDN), dissolved organic nitrogen (DON) and dissolved organic carbon (DOC) concentrations and flux were measured for one year in bulk deposition and throughfall from three stand types (upland deciduous, upland conifer and wetland conifer) on the Boreal Plain, Canada. Annual (November 2006 to October 2007water year) flux rates in bulk depositionwere 80...

We estimated the genetic parameters related to feed intake (FI), feed efficiency traits (including feed conversion ratio (FCR) and residual feed intake (RFI) of digestible crude protein (DCP) and total digestible nutrients (TDN)), beef marbling score (BMS), melting point of fat (MP) and fatty acid composition. Fat and meat (Musculus trapezius) samples were taken from the carcasses of 863 Japane...

Genes encoding an aniline dioxygenase of Frateuria sp. ANA-18, which metabolizes aniline via the ortho-cleavage pathway of catechol, were cloned and named tdn genes. The tdn genes were located on the chromosomal DNA of this bacterium and weren't clustered with catechol-degrading gene clusters. These results show that the ANA-18 aniline-degrading gene cluster is constructionally different from P...

Two data sets were developed to evaluate and refine feed energy predictions with the beef National Research Council (NRC, 1996) model level 1. The first data set included pen means of group-fed cattle from 31 growing trials (201 observations) and 17 finishing trials (154 observations) representing over 7,700 animals fed outside in dirt lots. The second data set consisted of 15 studies with indi...

We are developing a plan construction and plan execution monitoring system to automate the operation of the communications link in NASA’s Deep Space Network (DSN). The objectives of this effort are: (1) to archive knowledge of operations procedures; (2) provide a capability to assist in execution monitoring; and (3) provide a capability for automatically constructing the plan to be executed and...

Longstanding observations suggest that dissolved materials are lost from fresh litter through leaching, but the role of soil fauna in controlling this process has been poorly documented. In this study, a litterbag experiment employing litterbags with different mesh sizes (3 mm to permit soil fauna access and 0.04 mm to exclude fauna access) was conducted in three habitats (arid valley, ecotone ...
