An immunohistological method (Shintaku-Said method) for the demonstration of oestrogen receptors in routinely processed paraffin wax embedded tissue was applied to 19 cases of mucinous carcinoma of the breast. Seventeen (89%) tumours showed variable degrees of positivity and two were negative. In eight cases the receptors were also assayed biochemically using a dextran-coated charcoal method, a...

The prevention of wax formation under high pressure on new diesel engine requires a good understanding of the behaviour of the paraffin molecules crystallization. In this work a diesel from a Petrogal refinery was investigated under pressure. In particular the melting curve was measured from atmospheric pressure to 100 MPa by an optical technique. The behaviour of the solid phase with the press...

To address the drawback of low thermal conductivity conventional organic phase change materials (PCMs), a paraffin-wax-based composite (PCC) was assembled via vacuum impregnation method, using new type carbon fiber network material as supporting matrix. The sheet (CFS) exhibited structure comprising high-thermal-conductivity fibers, beneficial for enhancing heat transfer properties PCC. sheet-s...

The present experimental study reports the thermal performance analysis of a phase change material (PCM)-basedfinned heat sink placed on silicone rubber heater which mimics CPU chip and is cooled by natural forced convection. subjected to constant cyclic loading for five input power values (4, 6, 8, 10, 12 W). Paraffin wax 1-hexadecanol are selected as PCM this study, have melting points in ran...
