We describe the clinical and pathologic observation of four patients with Porokeratosis of Mibelli. Allof them were women. They had four different forms of disease: Plaque type, functate form, Linear form and superficial disseminated form. In histologic features we observed a new change in basement membrane of epidermis in two patients. This change composed of Liquefaction degeneration of basal...

PURPOSE To evaluate morphologic aspects of age-related liquefaction of the human vitreous body by light and electron microscopy to provide a basis from which future studies directed at the pathogenesis of this phenomenon can be undertaken. The study focuses on changes in fibrillar collagen and proteoglycans (PGs). METHODS Morphologic aspects of intravitreal liquefied spaces and matrix areas s...

We investigated hydrothermal liquefaction of Nannochloropsis sp. at different temperatures (250e400 C), times (10e90 min), water densities (0.3e0.5 g/mL), and biomass loadings (5 e35 wt %). Liquefaction produced a biocrude with light and heavy fractions, along with gaseous, aqueous, and solid by-product fractions. The gravimetric yields of the product fractions from experiments at 250 C summed ...

Fish sauce production is a very long process and there is a great interest in shortening it. Among the different strategies to speed up this process, the addition of external proteases could be a solution. This study focuses on the effect of two commercial enzymes (Protamex and Protex 51FP) on the proteolysis of two fish species traditionally converted into fish sauce: sardine and anchovy, by c...

Wood liquefaction using an organic solvent and an acid catalyst has long been studied as a novel technique to utilize biomass as an alternative to petroleum-based products. Oxalic acid is a weaker organic acid than a mineral acid and wood liquefaction with oxalic acid as a catalyst will result in a higher amount of wood residue than that with a mineral acid. Yet the wood residue can be used as ...

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...

Instability of liquefaction is one of the major reasons which results in the failure of earth structure such as dam. The present study focuses on the simulation of static liquefaction behavior for granular materials such as sand and sand-silt mixtures. Based on micromechanical analysis of inter-particle behavior, a simple one-scale model is proposed to simulate the stress-strain response of san...

Iran is an active seismic region. Earthquake damage is commonly controlled by three interacting factors including source and path characteristics, local geological and geotechnical conditions and type of the structures. Obviously, all of this would require analysis and presentation of a large amount of geological, seismological and geotechnical data. In this paper, nonlinear geotechnical seismi...
