Although a number of recent studies have focused on the existence of a non-negligible sire contemporary group interaction effect (s) affecting the estimation of genetic parameters for maternally influenced traits in beef cattle, the assessment and interpretation of this effect using field data remains poorly understood. In this study 27,639 records of both birth weight (BW) and weaning weight (...

The aim of this paper is to show a method that is able to detect a particular class of semantic inconsistencies in a deductive system (DS). A DS verified by this method contains a set of first order production rules, and a description logic terminology that defines the domain problem. By building an ATMS-like theory the method is able to give an specification of all the initial Fact Bases (FBs)...

In this paper, the conservation laws of classical fluid mechanics are used to derive a quasi-one-dimensional model of fluid flow in an elastic tube of time-varying cross-sectional area, representing the human vocal tract. The global flow equations are then decomposed into aerodynamic and acoustic components, representing respiratory flow and sound propagation during speech. The nature of the co...

Crop production is threatened by the increased nitrogen (N) input and declining N use efficiency (NUE). Information on total N input from planted seeds/tubers, atmospheric deposition, irrigation water, crop residues, animal manure, biological N fixation, and synthetic N fertilizer and NUE based on these N inputs in China’s crop production is limited. We calculated the amount of various N inputs...
