The article interprets the methodological potential of Hegel’s speculative dialectics as a possible course spiritual evolution Absolute subject. intention is towards method, first through very construction “idea freedom” from point view Logic; second, constitutive function freedom and transition subjective spirit into objective spirit; third, unfolding mediation in realms spirit. This essential...

Small addition of oxygen is currently used to improve the mechanical properties titanium. It has been thought, until now, that fully dissolves in titanium matrix, thus leading a solid solution. However, we show here, with transmission electronic microscopy and X-ray diffraction, can also form ordered precipitates Ti6O-type structure, even for concentration as low 0.15 wt% O. The found series pu...

Abstract The metal materials corrosion in the boiler steam-water system influences safe and economic operation of system. In this work, experiment carbon steel is carried out high-temperature autoclave to simulate effect temperature dissolved oxygen on studied by weight loss rate, surface changes micro-morphology characterization. At 120~150°C, mainly dissolves pure water many spots are formed ...

Chemical reactions can impact mixing in partially miscible stratifications by affecting buoyancy-driven convection developing when one phase dissolves into the other one in the gravity field. By means of combined nonlinear simulations and experiments, we explore the power of an A + B → C type of reaction to either enhance or refrain convective dissolution with respect to the nonreactive system ...

Carbon Capture and Storage (CCS) is a method to reduce anthropogenic greenhouse gas emissions thereby mitigating global warming. In CCS, carbon dioxide (CO2) is captured from fossil fuel-fired power plants or other large point-source emitters, purified, compressed and injected deep underground into subsurface formations at depths of or greater than 800m. At such depths CO2 is in a supercritical...

Analyses of service in The Changeling have focused on De Flores as an embodiment contemporary fears about servants, neglecting his mistress's agency and the play's engagement with anxieties women's authority, especially their power over servants. They also ignore two other Diaphanta Lollio, whose relationships mistresses are equally revealing those anxieties. This article argues that stages all...

This paper investigates joint bidding when firms have incentives to sign subcontracts with each other after competing in the stage. A consortium affects horizontal subcontracting market and, through backward induction, alters firms’ bids. Our findings challenge current legal practice that consortia without efficiencies must pass “no-solo-bidding test”, requiring its members could not bid stand-...

This study was undertaken to investigate the effects of Cu and solution heat treatment on the microstructure and hardness of cast Al-Al4Sr metal matrix composite. Different amounts of Cu (0.3, 0.5, 1, 3 and 5 wt.%) were added to the composite. Specimens were heat treated at 500 °C for 4 hours followed by water quenching. Microstructural studies were assessed by the use of optical microscope, sc...
