This experiment was conducted to evaluate the intake, nutrient apparent digestibility and the effect of total collection days (two and four days) on apparent digestibility estimates for lambs fed diets containing sugar cane treated with calcium oxide (CaO). Eight Santa Inês castrated male lambs with a 16.6±1.8 kg body weight were used. The lambs were distributed in two 4×4 Latin squares, with f...

This paper describes the concept of Time-Expanded Decision Networks (TDNs), a new methodology to design and analyze flexibility in large-scale complex systems. This includes a preliminary application of the methodology to the design of Heavy Lift Launch Vehicles for NASA’s space exploration initiative. Synthesizing concepts from Decision Theory, Real Options Analysis, Network Optimization, and ...

CDOM biogeochemical cycle is driven by several physical and biological processes such as river input, biogeneration and photobleaching that act as primary sinks and sources of CDOM. Watershed-derived allochthonous (WDA) and phytoplankton-derived autochthonous (PDA) CDOM were exposed to 9 days of natural solar radiation to assess the photobleaching response of different CDOM sources, using absor...

Abstract The objective of this study was to compare residual feed intake (RFI) and greenhouse gas exchange in mature beef cows during gestation lactation when consuming an unprocessed, grass hay diet. Twenty-six Angus x Hereford (4.5 ± 0.0 yr) were used two voluntary studies. Cows evaluated mid-gestation (GEST) late (LACT). Unprocessed (GEST = 8.73% CP 59.25% TDN; LACT 8.31% 54.50% TDN) a miner...

Photoselective shading is a process that modulates the radiation intensity in specific regions of electromagnetic spectrum. It common practice horticulture to manipulate plant physiological responses, but date has only received minimal attention viticulture. The potent odorant 1,1,6-trimethyl-1,2-dihydronaphthalene (TDN) particular relevance for aged Riesling wine, which are also known be impac...

Nitrogen (N) plays an important role in marine ecosystems as a biogenic element for phytoplankton. The tidal cycle had major influence on various biogeochemical parameters of the bay and changed nutrients input with ebb flow tide. In this study, we collected samples from Shuidong Bay (SDB) China, August 2021, to explore periodic variations coastal waters during spring neap tides. effects tides ...

Deep learning technology has been extensively explored by existing methods to improve the performance of target detection in remote sensing images, due its powerful feature extraction and representation abilities. However, these usually focus on interior features target, but ignore exterior semantic information around especially object-level relationship. Consequently, fail detect recognize tar...

The unique relationship between TDN and CP concentration (low CP relative to TDN) in the whole-plant of 'Floralta' limpograss (Hemarthria altissima) may provide an opportunity for improving cattle performance through protein supplementation. In each of three consecutive years, yearling Brahman x British crossbred steers (initial weight approximately 270 kg) grazed limpograss during the summer a...

Trial 1, 135 crossbred cows with calves were used to compare limit-fed corn-hay diets with ad libitum hay and cracked with whole corn in limit-fed diets. Diets were to supply similar TDN intakes. Cow-calf pairs were fed treatment diets from 24 h after parturition until the beginning of the breeding season (62+/-13 d). Cow and calf performance was not affected (P > .05) by intake level or corn p...

Two trials were conducted to evaluate the effects of dietary NPN levels on animal performance, diet digestibility, ruminal characteristics, and microbial efficiency. Experiment 1 was conducted with 24 Holstein x Nellore crossbred steers (350 +/- 20 kg of BW) distributed in 6 blocks to evaluate intake and digestibility of nutrients and performance. The diets consisted of 70% corn silage and 30% ...
