In this report, we describe the synthesis of a molecularly imprinted polymer (MIP) nanotube membrane, using porous anodic alumina oxide (AAO) membrane by surface-initiated atom transfer radical polymerization (ATRP). The use MIP in chemical separations gives advantage high affinity and selectivity. Furthermore, because molecular imprinting technique can be applied to different kinds target molecules, ranging from small organic molecules peptides proteins, such membranes will considerably...

Fracture is one of the most common and unexpected traumas. If not treated in time, it may cause serious consequences such as joint stiffness, traumatic arthritis, nerve injury. Using computer vision technology to detect fractures can reduce workload misdiagnosis also improve fracture detection speed. However, there are still some problems sternum detection, low rate small occult fractures. In this work, authors have constructed a dataset with 1227 labelled X-ray images for detection. The...

Eosinophilic fasciitis (EF) is a rare connective tissue disorder characterized by the involvement of dermis, subcutaneous tissue, and fascia. The treatment for EF usually involves long-term use glucocorticoids immunosuppressants. Patients with are at risk developing third-degree atrioventricular (AV) block during course disease. distinctive features EF, side effects its treatment, inherent limitations transvenous pacemakers (TVPs) present significant challenges in management patients who...

In order to explore the metallurgical behavior and mechanism of bottom blowing CO 2 in ladle furnace (LF), was introduced LF refining process. The kinetics thermodynamics were investigated several mathematical models for kinetic study established. Some exploratory industrial experiments have been conducted with different proportion a 70 ton LF. results indicated that it could lead little oxidation elements molten steel processing compared Ar stirring. average amount C range 0.3–0.8 kg. Mn...

Serious efforts have been carried out in China towards the utilization of CO2 different metallurgical processes. The research was initiated from feasibility study used steel making process, followed by use decreasing dust generation and further improving dephosphorization efficiency converter process. Industrial experiments on bottom blowing BOF electric arc furnace plant with positive results. is applied LF process for inclusions removal continuous casting as shielding gas. also stainless...

Oil well cement microcracks cause formation fluid channeling, compromising oil and gas extraction safety. Superabsorbent polymer (SAP) can absorb water swell to prevent channeling. In this study, an alkali-resistant pH-sensitive SAP was prepared based on the properties of slurry. The preparation optimized, including monomer ratio, cross-linking agent dosage, concentration. pH sensitivity alkali resistance were evaluated. results revealed that exhibited good sensitivity, with absorption rate...

A theoretical generic model describing the mass transfer phenomena between rising gas bubbles and a metal bath has earlier been developed by present authors, to predict composition change in melt as .consequence of blowing different oxidant gases.In order verify predictions, series experiments involving reactions Fe-Cr-C melts O 2 -CO mixtures were carried out.The results showed that decarburization deviates significantly from thermodynamic paths predicted on basis bulk compositions was able...

Carbothermic reduction of chromite is an important industrial process for extracting chromium from the chromite. To have a better understanding effect iron on carbothermic chromite, synthetic (FeCr2O4) by graphite with/without addition powder was investigated in this paper Thermogravimetric Analysis (TGA) argon atmosphere. The fractional reduced samples were examined SEM/EDS and XRD analysis, thermodynamically kinetically evaluated. experimental results show that enhances FeCr2O4 increases...

Abstract In this paper, a class of single‐master‐multiple‐slaves (SMMS) bilateral teleoperation systems with the limitation communication bandwidth is investigated. The signals are exchanged between master and slaves through delayed communication. Besides, to avoid data collisions, Try‐Once‐Discard (TOD) scheduling protocol utilized decide which slave gets network access at each triggered instant. A control algorithm event‐triggered mechanism proposed ensure master–slaves synchronization....

The mechanical properties of fractured rock mass are largely dependent on the fracture structure under coupling freeze-thaw cycles and large temperature difference.Based traditional macroscopic continuum theory, thermal model corresponding theories ignore material internal characteristics, which add difficulty in describing mesoscopic behavior among different phases.In order to uncover inherent relationship laws crack development, structural change physical strong cold frost weathering area,...

With the rapid development of cross-border e-commerce, however, logistics has become a bottleneck in electricity traders. The results studies on e-commerce are still less, and relevant theoretical not yet mature enough. As occupies share foreign trade increases, so does their influence. In order to eliminate bottlenecks an electric enterprise, it is great importance systematically study issues synergy supply chain enterprise validate how traders work together using discussion based...

Abstract To study the final equilibrium state and process of CO 2 injecting into Fe–C melt with different initial carbon contents, a model was established based on method minimization Gibbs free energy corresponding experiments were carried out in high-temperature tube furnace. When is continuously injected at 1873 K, system such that oxygen contents are 0.1977 0.0115 wt pct, respectively, volume ratio gas phase 85.75 vol pct. [O] × [C] greater than those under 0.8575 atm, removes from melt....
