Knowledge about the seismic elastic modulus dispersion,and associated attenuation,in fluid-saturated rocks is essential for better interpretation of seismic observations taken as part of hydrocarbon identification and time-lapse seismic surveillance of both conventional and unconventional reservoir and overburden performances.A Seismic Elastic Moduli Module has been developed,based on the forced-oscillations method,to experimentally investigate the frequency dependence of Young's modulus and Poisson's ratio,as well as the inferred attenuation,of cylindrical samples under different confining pressure *** with three standard samples showed that the measured elastic moduli were consistent with the published data,indicating that the new apparatus can operate reliably over a wide frequency range of f∈[1-2000,10^(6)]*** Young's modulus and Poisson's ratio of the shale and the tight sandstone samples were measured under axial stress oscillations to assess the frequency-and pressure-dependent *** dry condition,both samples appear to be nearly frequency independent,with weak pressure dependence for the shale and significant pressure dependence for the *** particular,it was found that the tight sandstone with complex pore microstructure exhibited apparent dispersion and attenuation under brine or glycerin saturation conditions,the levels of which were strongly influenced by the increased effective *** addition,the measured Young's moduli results were compared with the theoretical predictions from a scaled poroelastic model with a reasonably good agreement,revealing that the combined fluid flow mechanisms at both mesoscopic and microscopic scales possibly responsible for the measured dispersion.

Objective: The objective of this study was to explore the safety, efficacy, economy, and other aspects of frequently-used antitumor Chinese patent medicine injections through a comprehensive evaluation of evidence-based medical research to provide scientific information and decision-making basis for drug selection, rational drug use, public awareness of safe drug use, and medical insurance. Materials and Methods: The names of five frequently used antitumor Chinese patent medicine injections were used as search terms, including the compound Sophora flavescens injection, Kangai injection, Aidi injection, Kanglaite injection, and Brucea javanica oil emulsion injection. Relevant evidence-based medical research was extracted from the databases. A descriptive evaluation was conducted, and the Markov model was used for the cost-benefit analysis. Finally, the above injections are ranked by comprehensive scores using the multi-criteria decision analysis and Delphi method. Results: The five injections had their own advantages in enhancing the effectiveness of anti-tumor treatments, improving the quality of life for cancer patients, and reducing the incidence of adverse reactions. From the perspective of economy and other attributes, compound S. flavescens was superior to B. javanica oil, Aidi, Kangai, and Kanglaite. After a comprehensive evaluation of the above five injections, the compound S. flavescens injection received the highest score. Conclusions: Compound S. flavescens, Kangai, Aidi, B. javanica oil, and Kanglaite have their own advantages in effectiveness and no significant difference in safety. Compound S. flavescens injection has the highest comprehensive score. Clinical attention should be paid to monitoring the initial stage of medication and special groups.

This research evaluated the effects of copper(Cu)on intestinal antioxidant capacity and apical junctional complex(AJC)in juvenile grass carp.A total of 1080 healthy juvenile grass carp(11.16±0.01 g)were fed six diets including different dosages of Cu,namely 0,2,4,6,8 mg/kg(Cu citrate[CuCit]as Cu source)and 3 mg/kg(CuSO4·5H2O as Cu source).The trial lasted for 9 *** findings revealed that dietary optimal Cu supplementation(2.2 to 4.1 mg/kg)promoted intestinal growth,including intestinal length,intestinal length index,intestinal weight,and intestinal somatic index(P 0.05).On the other hand,optimal Cu increased intestinal tight junction(TJ)proteins(except for claudin 15b)and adherens junction(AJ)proteins(E-cadherin,α-catenin,β-catenin,nectin and afadin)mRNA levels(P<0.05),which could be connected to the signaling pathway formed by the Ras homolog gene family,member A(RhoA),Rho-associated kinase(ROCK),and myosin light chain kinase(MLCK).Finally,based on serum indicator D-lactate and intestinal oxidative damage index(ROS),Cu requirement(CuCit as Cu source)for juvenile grass carp from initial weight to final weight(from 11 to 173 g)was determined to be 4.14 and 4.12 mg/kg diet,*** work may provide a theoretical foundation for identifying putative Cu regulation pathways on fish intestinal health.
