Li) A concrete slatted floor system that consists of a narrow-gap slatted floor and beneath it a slope bottom for separation of faeces and urine in pig houses was investigated. In the experiments, four concrete slatted floors with one of two slat profiles and one of two gap widths, and a steel wire slatted floor were studied ...

We use a 3-D general circulation model to compare the primitive Martian hydrological cycle in “warm and wet” and “cold and icy” scenarios. In the warm and wet scenario, an anomalously high solar flux or intense greenhouse warming artificially added to the climate model are required to maintain warm conditions and an ice-free northern ocean. Precipitation shows strong surface variations, with hi...

this work presents an experimental investigation of the influence of the six important machining parameters (tool nose radius, tool rake angle, feed rate, cutting speed, cutting environment (dry, wet and cooled) and depth of cut) on surface roughness & material removal rate in the machining unidirectional glass fiber reinforced plastics (ud-gfrp) composite using carbide (k10) cutting tool durin...

inhibitory effect of three benzothiazole derivatives (1, 3-benzothiazol-2-amine (bta), 6-methyl-1, 3-benzothiazol-2-amine (mbta) and 2-amino-1, 3-benzothiazole-6-thiol (tbta)) on corrosion of carbon steel has been studied using density functional theory (dft) method in gas and aqueous phases. quantum chemical parameters such as ehomo (highest occupied molecular orbital energy), elumo (lowest un...

Molecular dynamics simulations have been performed to determine the partitioning behaviour of organic compounds between water phases and inorganic surfaces. In the ®rst of these sets of simulations the heat of adsorption of a single benzocarbazole molecule on water-wet kaolinite surfaces was determined. The results from these simulations show that the benzocarbazole isomers have a slight prefer...

A kind of bioinspired heterostructured bead-on-string fiber (BHBF), composed of poly-(methyl methacrylate) (PMMA) and titanium tetrachloride (TiCl4) hydrolyzed nanoparticles, was prepared via integrating a wet-assembly system, including PMMA electrospinning, fog of nanoparticles and water coalescence at multi-stages. The wet-assembly of BHBF was regulated by the difference in surface energy and...

Water plays a fundamental role in affecting geochemical transport and physical properties of magmas. Here we show the previously undocumented behavior of water within partially molten silicate resting in a temperature gradient, producing O, Li and H isotope redistribution by thermal diffusion leading to enrichment of light isotopes at the hot end of the gradient. After weeks to months, fully mo...

Given a segmented CT scan data of the colon represented as a triangle mesh, our water-plane algorithm will detect polyp candidates. The water-plane method comprises of pouring water into a polyp protrusion from the outside of the colon and in raising the “water-plane” until it cannot be incremented any further without causing water leakage. The method starts at a vertex and uses average normal ...

When a wetting liquid wicks into a fibrous material, it causes the material to deform. In this paper we discuss the elastocapillary effect that leads to spontaneous internal stresses in the materials. The elasto-capillary effect produced by menisci in pores can be identified through a specific stress distribution in the fibrous matrix. We show that the classical Bernoulli problem of a freely ha...
