Multi-stage compression is the normal method to achieve pipeline pressures of 100 bara for the transport of carbon dioxide (CO2) after capture in a carbon capture and storage (CCS) scheme. An alternative method is to partially compress the gas, liquefy it and then pump the liquid CO2 to the required pressure. The advantage of this process is that the CO2 stream can be further purified through l...

Certain specimens of human semen shorten the coagulation time of whole blood because of the presence of active thromboplastic agents, while other samples prolong its coagulation time. Human prostatic fluid in large amounts always delays or abolishes blood coagulation. The delay or absence of clotting is counteracted by adding calcium ions and is due to the large concentration of citrate in pros...

Research in the pathophysiology of retinal detachments would be aided if an experimental model of such a lesion could be achieved. In an attempt to produce such a model, it was felt essential to cause vitreal as well as retinal alterations. This role of vitreoretinal adhesions and liquefaction of the vitreous as the two main anatomic factors in the etiology of the idiopathic type of retinal det...

Microscopic examination of respiratory specimen for Acid Fast Bacilli (AFB) plays an important role in the initial diagnosis of tuberculosis as well as for monitoring of antitubercular treatment. Direct microscopy of sputum has a low sensitivity.[1] Previous studies have shown that concentration and liquefaction of sputum signiÞ cantly improves the sensitivity of direct microscopy.[2] In the pr...

Parallel computing is a promising approach to alleviate the computational demand in conducting largescale finite element analyses. This paper presents a numerical modeling approach for earthquake ground response and liquefaction using the parallel nonlinear finite element program, ParCYCLIC, which is designed for distributed-memory message-passing parallel computer systems. In ParCYCLIC, finite...

The critical Casimir force provides a thermodynamic analogue of the quantum mechanical Casimir force that arises from the confinement of electromagnetic field fluctuations. In its thermodynamic analogue, two surfaces immersed in a critical solvent mixture attract each other due to confinement of solvent concentration fluctuations. Here, we demonstrate the active assembly control of colloidal eq...

One of the promising avenues for biomass processing is the use of water as a reaction medium for wet or aquatic biomass. This review focuses on the hydrothermal catalytic production of fuels and chemicals from aquatic biomass. Two different regimes for conversion of aquatic biomass in hydrothermal conditions are discussed in detail. The first is hydrothermal liquefaction, and the second is hydr...

The 2002 Molise earthquake, which was defined by seismologists as a normal event in the geodynamics of the Italian peninsula but had an international resonance due to the collapse of a primary school, triggered a series of research initiatives in earthquake engineering and significant modifications to building codes in Italy. The modifications were completed at the beginning of 2008 with the re...

Fe3O4 nanoparticles were prepared by a simple solid-state method under ambient conditions. The obtained nanoparticles, with small size and large surface area, were used as a catalyst for direct coal liquefaction (DCL). The results display that high conversion and oil yield were achieved with the nanocatalysts in direct liquefaction of two kinds of coals, i.e., Heishan coal and Dahuangshan coal....
