We report the observation of a premelting transition at chemically sharp solid-liquid interfaces using molecular-dynamics simulations. The transition is observed in the solid-Al-liquid-Pb system and involves the formation of a liquid interfacial film of Al with a width that grows logarithmically as the bulk melting temperature is approached from below, consistent with current theories of premel...

A solar thermal collector is a heat that absorbs via sunlight. It device turns the energy in sunshine or radiation into useful and storable form. This conveyed electromagnetic with wavelengths ranging from infrared (long) to ultraviolet (short). Solar one of cleanest most versatile renewable sources when compared other sources. trough collectors (PTC), Compound Parabolic Collectors (CPC), Linea...

Liquid-liquid-solid transitions (LLST) are known to occur in confined liquids, exist in supercooled liquids and emerge in liquids driven from equilibrium. Molecular dynamics (MD) simulations claim many successes in forecasting the phenomena. The transitions are also studied in the framework of thermodynamics based methods and minimalistic models. In here, the proposed approach is derived in the...

the objective of this study was to test whether the stimuli of osmotic pressure (op), vfa or ph in the omasum would affect the passage of digesta from the rumen and feed intake in sheep. five experements were carried out. different solutions with specific, op, vfa concentration and ph were infused into the omasal body. rumen digesta volumes and outflow rates (liquid and solid) were measured by ...

Objective Fusions involving neurotrophic tyrosine receptor kinase ( NTRK ) are known oncogenic drivers in a broad range of tumor types. It recently gained attention as predictor targeted therapy since selective inhibitors now approved the US and Europe for patients with solid tumors harboring gene fusions. However, estimation fusion/alteration frequency its clinicopathological characteristics p...

Stereo-lithography is a distinctive form of technology which permits for the translation of computer aided design illustration to3D solid items within hours. In Stereo-lithography melted plastic is solidified in particular patterns by laser beam consequential in solid epoxy realization of a 3D project. This ultraviolet laser beam is directed by CAD data. Parts created using Stereo Lithography m...

This work investigates the effect of different conditions of PFO thermal cracking from two PFO samples on liquid, solid and gas product yield and asphaltene removal efficiency in a new designed experimental setup. No need to use a catalyst, simple operating system and experiment conditions, the ability to use water as a cheap carrier gas and high asphaltene extraction efficiency without the use...

objective: pseudotumor cerbri (ptc) is a clinical syndrome characterized by increased intra-cranial pressure (icp) without any evidence of a mass lesion or any obstructive process. the incidence is 0.9-2 per 100.000 people. it is more frequent in adults in the 20-30 years age group, especially obese women, and less common in pediatric age groups; 11-16 years old children may however suffer from...
