Data Curation For Modeling Tall Fescue Biomass Dynamics With Dssat-Csm, M. B. Hanson, P. D. Alderman, T. J. Butler, A. Caldeira Rocateli
Data Curation For Modeling Tall Fescue Biomass Dynamics With Dssat-Csm, M. B. Hanson, P. D. Alderman, T. J. Butler, A. Caldeira Rocateli
IGC Proceedings (1997-2023)
While models for predicting forage production are available to aid management decisions for some forage crops, there is limited research for a yield model designed specifically for tall fescue (Schedonorus arundinaceus). Therefore, our objective was to adapt an existing perennial forage model, the Decision Support System for Agrotechnology Transfer Cropping Systems Model (DSSAT-CSM) for predicting forage biomass of tall fescue in the southern Great Plains. To evaluate model performance, there must first be a high level of data manipulation and cleaning. In this project, a cohesive dataset combining biomass, weather, soil, and management data were structured into DSSAT …
Priority Areas For Action And Research On Pastoralism And Rangelands In Eastern Africa, M. O. Odhiambo
Priority Areas For Action And Research On Pastoralism And Rangelands In Eastern Africa, M. O. Odhiambo
IGC Proceedings (1997-2023)
There is an element of irony around pastoralism and research in Eastern Africa. While it is one of the most researched production and livelihood systems, pastoralism is also the least understood by policymakers and development actors, with discussions about its importance characterized by significant gaps in knowledge. What is more, policy actors have difficulties accessing empirical data specific to pastoralism and rangelands in a form that allows well-founded decision-making on policy and action. Most available data tend to be out of date and not disaggregated with reference to pastoralism and rangelands. As a result, much of the discourse around pastoralism …
Methane Emission Estimated From Different Cattle Intake Data In Heifers Grazing A Tropical Pasture, José Augusto Imaz, O. Hernández, D. Dos Santos, A. Radrizzani, J. I. Arroquy
Methane Emission Estimated From Different Cattle Intake Data In Heifers Grazing A Tropical Pasture, José Augusto Imaz, O. Hernández, D. Dos Santos, A. Radrizzani, J. I. Arroquy
IGC Proceedings (1997-2023)
The quantification of methane (CH4) from enteric fermentation related to cattle diet is a useful tool to identify strategies to mitigate greenhouse gas emissions. This is even important in tropical and subtropical regions due to the lack of CH4 estimations in beef cattle, particularly from Bos Indicus breeds grazing tropical grasses (Kurihara et al., 1999). Several modelling approaches have been developed in order to predict CH4 emission. However, the use of these models has limitations associated with uncertainty information required such as feed intake (FI), composition of the selected diet and animal responses (Gonzalez et …
Harnessing The Data Revolution, Chaitan Baru
Harnessing The Data Revolution, Chaitan Baru
Commonwealth Computational Summit
Harnessing Data for 21st Century Science and Engineering (aka Harnessing the Data Revolution, HDR) is one of NSF's six "Big Research Ideas," aimed at supporting fundamental research in data science and engineering; developing a cohesive, federated approach to the research data infrastructure needed to power this revolution; and developing of a 21st-century data-capable workforce. HDR will enable new modes of data-driven discovery allowing researchers to ask and answer new questions in frontier science and engineering, generate new knowledge and understanding by working with domain experts, and accelerate discovery and innovation. This initiative builds on NSF's history of data science investments. …
X-Ray Irradiation Apparatus In Which An X-Ray Source Is Energized Upon The Recording Of Irradiation Dosage Data, George S. Hurst, Norbert Thennard, Karl A. Schneider
X-Ray Irradiation Apparatus In Which An X-Ray Source Is Energized Upon The Recording Of Irradiation Dosage Data, George S. Hurst, Norbert Thennard, Karl A. Schneider

Apparatus for use in examining or treating patients with X-radiation or the like requires the making of a permanent record of the radiation applied. The operation of the radiation source is controlled in dependence upon the making of the record and the to radiation, or dose exposure is limited to a predetermined amount. A method is disclosed for safeguarding the patient and for producing a tangible record of the dose to which the patient is subjected.
