Evapotranspiration (ET) is a crucial process in the terrestrial water cycle, and understanding its stable isotopic evolution essential for comprehending hydrological processes. The Craig–Gordon (C-G) model widely used to describe fractionation during pure evaporation. However, natural environments, ET involves both transpiration (T) evaporation (E), traditional C-G does not account effect of on...
An underground coal gasification (UCG) process is strongly exothermic, which will cause thermal damage on rock cap. We proposed a new numerical model based two dimension particle flow code (PFC2D) to analyze the inception and extension of cracks pre-cracked red sandstone, were thermally treated at temperature 25~1000 °C. The results indicated that: (1) value DT obtained by extracting crack area...
Abstract The purpose of this experiment was to study the changes fecal bcteria calves before and after weaning. Among 365 Holstein born in 2021, 8 with similar body weight were selected weaning (60 ± 2 d) (120 6 d), rectal manure collected. Fecal samples for volatile fatty acids microorganisms. results showed that: 1) Sobs index, Ace Chao1 Simpson index Shannon pre-weaning post-weaning signific...
Background: Although the Transtheoretical Model (TTM) is promising for behavioral interventions, it may be limited by an inability to understand perceptions of food consumption. The following questions and gaps presented by the scientific community prompted this study: What is the concordance between perceived and actual food consumption? What proportions of individuals are in the pseudo-mainte...
BACKGROUND The developments in echocardiography or ultrasound cardiography (UCG) have improved our clinical capabilities. However, advanced hardware and software capabilities have resulted in UCG facilities of dubious clinical benefits. Is tissue Doppler echocardiography (TDE) is one such example? PRESENTATION OF THE HYPOTHESIS TDE has been touted as advancement in the field of echocardiograp...
The publication of this (1990) doctoral dissertation, written at the University of Clermont-Ferrand under Gabriel G. B6s, makes it possible to have in French a very useful reference work for syntactic systems based on generalized phrase-structure grammars (GPSGs) and unification categorial grammars (UCGs), as well as a good treatment of French syntax. Not only is the text very precise in its de...
The objective of this study was to determine the cost-effectiveness of eplerenone compared with usual care in patients with chronic heart failure and New York Heart Association (NYHA) Class II symptoms.A Markov model was constructed with 5 health states to reflect NYHA symptom status (Classes I-IV) and death. All subjects began in the "Class II" health state and then moved to other symptom heal...
OBJECTIVES Small pulmonary allografts are difficult to obtain, thus we now use a tailor-made right ventricle to pulmonary artery (RV-PA) conduit for the Ross procedure, consisting of a fresh non-treated autologous pericardial (AP) patch for the posterior wall and expanded polytetrafluoroethylene (ePTFE) monocusp patch for the anterior wall. Long-term durability and RV function were assessed. ...
