The fluid flow at a constant rate from both an infinite reservoir and a finite reservoir into a line source well were considered. Analytical solutions of the partial differential equation that governs the transient flow of fluid through a fractal reservoir were given by using the Laplace transformation and the property of the Bessel function for an infinite reservoir and finite circular reservoir. A large-time approximation solution for an infinite reservoir was also studied. Pressure transient behavior of fluid flow in fractal reservoir was analyzed by using analytical solution. Typical pressure curves were shown. An example was analyzed by using a large-time approximation solution for an infinite reservoir, and fractal parameters were obtained by employing oil reservoir description.

Magnesium alloys are light weight and exhibit good recyclability but suffer from low hardness and wear *** this study,the hardness and wear resistance of AZ31 magnesium alloy were improved by depositing diamond-like carbon(DLC)films as hard protective coatings using ion-beam-enhanced deposition with various CH4/H2 ratio,gas flow rates and accelerating *** supporting effect of the magnesium alloy was enhanced by the production of a graded interfacial layer which is composed of film atoms and substrate *** composition and mechanical properties of the DLC coatings were characterized using scanning electron microscopy(SEM),Raman spectroscopy,Rockwell test and *** tribological properties of the coating were also investigated using a frictional surface microscope with an in situ observation system and friction force *** DLC films were characterized by a lower intensity ratio of the D-peak to G-peak(ID/IG),higher hardness,and improved tribological properties when deposited at a lower accelerating voltage(6 kV).At the CH4/H2 ratio of 1:99 and 6 sccm/6 kV,minimum ID/IG values of 0.62,relatively low friction force value of 0.12 N,and a maximum hardness of 4056HV were attained *** addition,the DLC film exhibited improved wear resistance and a shallower wear track at this condition.

Through mechanical analysis, an improved hydraulic model for annular cuttings transport with foam was established for horizontal drilling. Based on the two critical inclination angles, the entire well was divided into three segments. The Bagnold stress, generalized power law rheological model and modified hindered particle settling velocity in foam fluid were adopted in the model to improve the simulation accuracy. The proposed model allows more precise prediction of cuttings transport property in the whole range of well inclination angle. Model performance was examined via case study and experimental data. Simulation results given by the propulsion iteration and trial-and-error method agree well with in-situ horizontal well drilling practice for the case study, and the comparison between the model prediction and Capo’s experimental data shows satisfactory agreement.

We discuss effects of the excitation frequency in an ac bridge differential capacitance transducer for the equivalence-principle test on the frequency-dependent characteristics of a practical operational amplifier, the thermal noise limitation, and stray-immune. Basic requirements of choosing the excitation frequency of the ac bridge capacitance transducer are given based on the three effects, which are significant for designing a capacitance transducer and choosing proper electric elements.

In this study,two casting speeds of 10 and 30 r/min were used in vertical twin-roll casting(TRC)to obtain Mg-rare earth(Mg-RE)alloys,and their microstructures,corrosion behaviours and in vivo bone reactions were investigated in *** results indicated that the roll-castings of TRC-30 r/min exhibited a finer grain size and higher volume fraction of non-crystallization than those in castings of TRC-10 r/***,the results of electrochemical impedance spectroscopy(EIS)and potentiodynamic polarization indicated that the castings of TRC-30 r/min displayed a higher corrosion resistance compared with those in the castings of TRC-10 r/*** tests showed that a higher degree of newly formed bone tissues was achieved by implants of TRC-30 r/***,in vivo tests displayed that degradation properties of the TRC-30-r/min implants were better than those of the TRC-10-r/min implants;furthermore,the degradation layer was a two-layer structure,and P and Ca were enriched in the outer degradation *** summary,these findings elucidated that casting speed has a substantial effect on the microstructure and degradation property of Mg-based implants,and the degradation property performs better with increased casting speed.

Proper timing of flowering under different environmental conditions is critical for plant *** quality is a pivotal environmental cue that plays a critical role in flowering *** tend to flower late under light with a high red(R)/far-red(FR)light ratio but early under light with a low R/FR light ***,how plants fine-tune flowering in response to changes in light quality is not well ***,we demonstrate that F-box of Flowering 2(FOF2),an autonomous pathway–related regulator,physically interacts with VASCULAR PLANT ONE-ZINC FINGER 1 and 2(VOZ1 and VOZ2),which are direct downstream factors of the R/FR light receptor phytochrome B(PHYB).We show that PHYB physically interacts with FOF2,mediates stabilization of the FOF2 protein under FR light and end-of-day FR light,and enhances FOF2 binding to VOZ2,which leads to degradation of VOZ2 by SCF^(FOF2) E3 *** contrast,PHYB mediates degradation of FOF2 protein under R light and end-of-day R *** interaction studies demonstrated that FOF2 functions downstream of PHYB to promote FLC expression and inhibit flowering under both high R/FR light and simulated shade conditions,processes that are partially dependent on VOZ *** together,our findings suggest a novel mechanism whereby plants fine-tune flowering time through a PHYB–FOF2–VOZ2 module that modulates FLC expression in response to changes in light quality.
