Dynamic viscosity of novel generated Copper Oxide (CuO)/Liquid Paraffin nanofluids is obtained experimentally for various temperatures and concentrations. To optimize the empirical process cost-efficiency, Feed-Forward Neural Networks (FFNNs) were modeled compared with Recursive Least Squares (RLS) Fuzzy model. prepare CuO/ liquid paraffin nanofluids, CuO nanoparticles are dispersed within para...
The expression of p53 in a variety of benign and malignant skin lesions has been first assessed in frozen sections and then compared with the results obtained in corresponding paraffin-embedded sections using various immunohistochemical staining methods with a panel of anti-p53 antibodies. Of the 48 benign and malignant skin lesions studied, 46(96%) had corresponding paraffin sections and immun...
Recent studies have reported that mutations of the epidermal growth factor receptor (EGFR) gene are associated with the responsiveness of tyrosine kinase inhibitors (TKIs), which are molecular targets for non-small cell lung cancer (NSCLC). To provide genetic analyses for NSCLC patients, a simple and reliable method using paraffin-embedded materials is needed. The DEXPAT DNA extraction kit was ...
Many technologies based on cells containing alkali-metal atomic vapor benefit from the use of antirelaxation surface coatings in order to preserve atomic spin polarization. In particular, paraffin has been used for this purpose for several decades and has been demonstrated to allow an atom to experience up to 10 000 collisions with the walls of its container without depolarizing, but the detail...
OBJECTIVE Anecdotal reports suggest that certain honey dressings have a positive effect on wound healing. However, there is limited empirical evidence supporting its use. This double-blind randomised controlled trial investigated the effect of a honey dressing on wound healing following toenail surgery with matrix phenolisation. METHOD Participants (n=100) were randomly assigned to receive ei...
To substitute for petroleum, Fischer-Tropsch synthesis (FTS) is an environmentally benign process to produce synthetic diesel (n-paraffin) from syngas. Industrially, the synthetic gasoline (iso-paraffin) can be produced with a FTS process followed by isomerization and hydrocracking processes over solid-acid catalysts. Herein, we demonstrate a cobalt nano-catalyst synthesized by physical-sputter...
AIMS To adapt the polymerase chain reaction (PCR) technique of HIV detection to paraffin wax embedded brain tissue and to compare the results with those obtained using frozen tissue. METHODS HIV antigen and HIV proviral DNA were detected in specimens of frontal lobe using immunohistochemistry and PCR, respectively. DNA was extracted from fresh tissue using standard methods whereas the techniq...
Thermo-optical switches are of particular significance in communications networks where increasingly high switching speeds are required. Phase change materials (PCMs), in particular those based on paraffin wax, provide wealth of exciting applications with unusual thermally-induced switching properties, only limited by paraffin's rather low thermal conductivity. In this paper, the use of differe...
We evaluated cells and lipids recovered in the bronchoalveolar lavage fluid from seven patients with liquid paraffin pneumonitis. For each patient, the BALF was whitish with oil droplets on the surface. Alveolar macrophages contained numerous, large vacuoles that did not react with May-Grunwald-Giemsa, Papanicolaou, or periodic acid-Schiff but were stained in black with Sudan B, orange with Sud...
This experimental study was conducted at the Fruit Research Institute, Cacak, Serbia, to determine bud break and callus formation dates, the degree of callus formation, grafting success on day 20 after grafting and overall grafting success on day 28 after grafting in walnut (Juglans regia L.) under different treatments and bench grafting conditions in cultivar Seinovo (control) and the selectio...
