Model Predictions

Stability of epoxy-polyurethane (EPU)/aluminum (Al) coatings (the change of coating emissivity during damp heat) was studied after exposure to the damp-heat test for varying lengths of time. We found that the emissivity increased with increasing heating temperature and time in damp heat. In addition, Arrhenius relationship was employed to calculate the lifetime of EPU/Al low infrared emissivity coatings in damp heat. Compared with observation data in damp heat, the calculated results validated the effectiveness of the model predictions, and showed that EPU/Al low infrared emissivity coatings exhibited good resistance to damp heat.

HeLa cells were grown for 2-3 days in EAGLE'S minimum essential medium with 10% calf serum (S-MEM; Seromed, München) and then incubated for 24 hours in serum free medium (MEM). After detaching the cells with a solution of 0. 14 % EDTA and 0. 07 % trypsin (Difco, 1 : 250) they were suspended in various solutions (S-MEM = control, MEM, buffered salt solutions with or without Me++ions, 0. 9 % NaCl solution) and allowed to settle on glass tube slips (Leighton-tubes). After 5, 10, 15, 20, 25, 30, 1 45, 60 minutes 2, 3, 4, 5 hours cells were prepared for scanning electron microscopy as described by Paweletz and Schroeter. The preparations were examined in a Jeol SEM (JSM-U3) at 25 KV without tilting.The suspended spherical HeLa cells are able to adhere to the glass support in all solutions. The rate of attachment, however, is faster in solutions without serum than in the control. The latter is in agreement with the findings of other authors.

Mineral Silicates

Asbestos is a generic name for a group of hydrated mineral silicates that occur naturally in a fibrous form. The early interactions of asbestos fibers with alveolar cells in large part determines their long-term toxicity. Young adult, SPF, Fischer rats were given a single intratracheal instillation of 2 mg crocidolite asbestos suspended in 0.5 ml of 0.9% NaCl solution. About 80% of the fibers had lengths of less than 10 ym as measured on light micrographs of the fiber suspension. Two rats were killed at 3 hr, 1 d and 1, 4, 8, 12 and 16 wk after instillation and the lungs instilled with 8 ml McDowell - Trumps at 20 cm H2O. Lung tissue was dehydrated and sputtered coated with palladium-gold for SEM or post-fixed in osmium tetroxide, embedded in epoxy resin and sections stained with uranyl acetate and lead citrate for TEM.

A stochastic approach has been developed to evaluate fatigue strength using elements of the fracture mechanics. The article presents a method for determining the initial parameters of statistical distributions. It also considers the method for constructing a fatigue curve for a component of any size and configuration with any given probability of failure.

Pharmacological Potential

Our present study focuses on the evaluation of the analgesic, anti-inflammatory and healing activity of Withania frutescens L. The anti-inflammatory result has an inhibition percentage of 78.87% ± 7.08 at 450 mg/kg and 75.14% ± 6.39 at 400 mg/kg and 89.75% ± 3.44 for diclofenac (1%). When applied locally, the 10% cream has an inflammation inhibition of 96.87% ± 5.85 and 76.14% ± 7.88 for the 5% cream with 89.87 ± 6.20 of reference (Indomethacin). The abdominal contractions of rats treated with the root extract are significantly lower than those of the control group that received only physiological NaCl solution, with 41.20 ± 2.30 for the extract and 82.20 ± 5.04 for NaCl and 53.40 ± 4.94 for the reference. The healing activity of the studied extract records a percentage of contraction of about 93.20% ± 3.36 (Extract 10%), 84.50% ± 3.84 (Extract 5%), 48.47% ± 2.15 (control) and 81.88 ± 2.24 for the reference.
