Abstract Shale gas reservoirs have poor physical properties and a large number of micro-nano pores have been developed. Shale gas wells have no natural productivity and need fracturing reconstruction measures to put into production. However, the fracturing fluid will enter the reservoir space of shale matrix after fracturing and affect the production of shale gas. At present, there is no consensus on the influence of fracturing fluid retention on gas well production. Based on this, the paper adopts gas molecular transport analyzer to carry out experimental research on the influence of fracturing fluid on shale gas diffusion law after entering matrix… More >

Abstract Present investigation aims at analyzing the properties of heat and transport phenomena of thermal energy and species mass in a non-Darcy Casson fluid flow induced by a erected porous elongated surface considering the effect of non-linear radioactive heat, thermophorosis, first order chemical reaction, Newtonian heating, thermo diffusion, permeability and slip conditions. Influence of critical parameters are widely studied. By inducing the variables of similarity the basic boundary layer equations are transmuted into dimensionless equations and are resolved arithmetically using Runge – Kutta – Fehlberg shooting techniques method. The dominance of critical parameters against velocity, temperature, and concentration are explicated through… More >

Abstract Present investigation aims at scrutinizing the properties of heat and mass transfer phenomena of liquid thin film of Casson Nano fluid over elongated sheet under the influence of thermophorosis and Brownian motion. Casson Nano particle effect on thermophorotic force and on Brownian force is studied. Variables of similarity were induced to transmute partial differential equations into dimensionless equations and are resolved numerically by elegant method bvp 4c. Thin film thickness is calculated using MATHEMATICA for different values of critical parameters. Velocity profiles diminishes for higher values of Casson parameter and magnetic field parameter. The temperature escalates for higher values of… More >

Abstract Ilex asprella (Hook. et Arn.) Champ. ex Benth is one of the most important traditional Chinese medicines in southern China. The seeds of Ilex asprella usually have extremely low germination due to their dormancy characteristics, which severely impacts the efficiency of seedling raising and increases labor costs. In this study, to improve the seed germination of I. asprella, the effects of germination substrate, hormone, winnowing, and stratification treatments on the seed germination of I. asprella were investigated. The results of the germination matrix showed that the highest germination percentage of 45.2% was achieved under the 20°C/10°C day/night temperature and vermiculite… More >

Abstract The aim is to assess the associations between social precariousness, perceived social support, and the return to work (RTW) in the first year following the beginning of adjuvant breast cancer treatment. Sixty-eight breast cancer patients encountered when starting their adjuvant treatment (T0) were followed up at 3 (T1) and 12 months (T2). Friends’ informative support at T0 favours the RTW at T1. Precariousness and negative support at T0 and T2 decrease the likelihood of RTW at T2. RTW support should be offered and tailored at the outset of treatment.

Abstract Context: Colon cancer is the third most diagnosed cancer in the world and has an impact on all aspects of the lives of patients and their partners. To date, few studies have examined patients’ sexual adjustment, and none have analyzed partner interactions.
Objective: The objective of this study is to describe the relationships between individual variables and couples’ emotional and sexual adjustments.
Method: Thirteen couples completed a set of questionnaires on social support, dyadic communication and coping strategies, and sexual satisfaction. Non-parametric analyses were performed on the quantitative data.
Results: Social support, communication, and dyadic coping strategies play a role… More >

Abstract In this paper, the influence of NaCl freeze-thaw (F-T) cycles and dry-wet (D-W) alternations on the flexural, compressive and bonding strengths of alkali-activated fly ash (FA) and a blast furnace slag powder (BFS) is investigated. The considered NaCl concentration is 3%. The effect of polypropylene fibers on the mechanical strengths is also examined. Scanning electron microscopy (SEM), thermogravimetry (TG) and X-ray diffraction (XRD) are selected to discern the mechanisms underpinning the NaCl-induced erosion. The obtained results indicate that the best results in terms of material resistance are obtained with admixtures containing 60% BFS and 40% FA in terms of mass… More >

Abstract Based on the Viscous Kelvin-Helmholtz theory used by D. Barnea & Y. Taitel (1993), a two-fluid stratified flow model of gas-liquid two-phase flow is established. Using the mathematical derivation, the influence of various influence factors on the stability of liquid level structure is synthesized. Compared with the criteria of D Barnea & Y. Taitel (1993) and Taitel & Dukler(1976) , and the algorithm of flow pattern transition criterion of stratified flow is proposed. According to the data of multiphase flow experimental loop, the influence of liquid viscosity and the instantaneous volume flow rate change of gas-liquid two-phase on the transition… More >

Abstract Nozzle flowmeter has simple structure and wide application. In order to study the influence of temperature change on the inner wall of nozzle flowmeter on the thermal effect of flowmeter, the thermal effect of nozzle flowmeter was numerically simulated at five different inner wall temperatures in this paper. It is found that with the increase of the inner wall temperature, obvious stress concentration occurs in the upstream and downstream pressure inlets and the inlet and outlet areas of the flowmeter, and the thermal stress increases with the increase of the wall temperature. There are large thermal deformation areas in the… More >

Abstract Recent years have witnessed an increase in the quantity of waste glass (WG) across the globe. Replacing the fine aggregate with WG is one of the steps toward preserving the natural resources of the environment and creating low-cost concrete. The present study is concerned with replacing fine aggregates with glass powder (GP) at (0%, 15%, 30%, and 50%). It has studied the fresh and hardened properties (compressive strength, tensile strength, hardened density, and slump) for all the mentioned percent replacements. The findings have shown that all mixtures containing GP gave acceptable slump results within the design limits (2–5 cm) according… More >
