Raman spectroscopy is a non-destructive, non-invasive, rapid and economical technique which has the potential to be an excellent method for the diagnosis of cancer and understanding disease progression through retrospective studies of archived tissue samples. Historically, biobanks are generally comprised of formalin fixed paraffin preserved tissue and as a result these specimens are often used...

“Bodies of tow and paraffin” is the phrase used by Georges Braque, pioneer with Picasso Cubism, to describe alarm that he felt at his first sight Les Demoiselles d'Avignon when paid a visit as was painting it in Bateau Lavoir 1907. This sums up well reactions work produced among friends Spanish painter who saw it. chapter summarises these horror, disgust disappointment Picasso's acquaintances. ...

Paraffin wax was microencapsulated by suspension polymerization with a polymer shell of methylmetacrylate (MMA)-styrene (St) copolymer. The influence of the copolymer/paraffin mass ratio and the MMA/St mass ratio on the encapsulation process and the physical properties of the microcapsules obtained were studied. It was observed that paraffin is difficultly encapsulated when the ratio polymer/pa...

This study describes results of a household survey conducted in Eshane in the rural Kwazulu-Natal Midlands in April 2002, including baseline sociodemographic, energy usage, paraffin-related injury and safety knowledge information. A total of 404 interviews were conducted in five villages that fell within a 10-kilometre radius of the proposed Eshane integrated Energy Centre. Paraffin usage was h...

A mathematical model for commercial naphtha catalytic reformer of Tehran refinery was developed. This model includes three sequencing fixed beds of Pt/Al2O3 catalyst at the steady state condition using detailed kinetic scheme involving 26 pseudo-components connected by a network of 47 reactions, in the range of C6 to C9 hydrocarbons. The reaction network consisted dehydrogenation, hydrogenation...

To establish the most proper method of in situ hybridization in detection of HCV-RNA in the liver, various detailed procedures were examined using frozen as well as paraffin-embedded sections of tissue derived from patients. In frozen sections of the liver from hepatitis C patients obtained at autopsy or surgery, HCV-RNA was detectable by in situ hybridization using thymine-thymine dimerized ol...

Paraffin odor intensity is an important quality indicator when a paraffin inspection is performed. Currently, paraffin odor level assessment is mainly dependent on an artificial sensory evaluation. In this paper, we developed a paraffin odor analysis system to classify and grade four kinds of paraffin samples. The original feature set was optimized using Principal Component Analysis (PCA) and P...

We report a distributed loaded line phase shifter based on a new class of electro-thermally actuated RF MEMS devices using paraffin phase-change material (PCM). Paraffin is a low loss (tan δ = 6.6×10−4) mechanical phase-change material that exhibits a 15% volumetric change through its solid-liquid transition. Due to its unique electrical and mechanical properties, paraffin PCM variable capacito...
