The moist-air entropy can be used to analyze and better understand the general circulation of the atmosphere or convective motions. Isentropic analyses are commonly based on studies of different equivalent potential temperatures, all of which are assumed to fully represent the entropy of moist air. It is, however, possible to rely on statistical physics or the third law of thermodynamics when d...

1) Skin or mucosal biopsy specimens are usually obtained by 3-5 mm punch or surgical biopsy. 2) Biopsy specimens are snap frozen. If there is a delay between biopsy and snap freezing, the specimen should be kept in cold saline. 3) Frozen 4-6μ sections are cut on a cryostat and placed on a glass slide before being air-dried for 15 minutes. 4) After rinsing in phosphate buffered saline (PBS), pH ...

A new species of Didymium (Myxomycetes), D. infundibuliforme, is described herein, and details are provided on its life cycle as observed in spore to spore culture on agar. The new species was recorded during intensive studies of areas of the Monte Desert in Argentina and the Atacama Desert in Chile. It has been collected directly in the field in both countries on several occasions over 4 y and...

A semi-quantitative latex agglutination test for bovine serum CRP levels has been established by mixing diluted serum (or diluted standard serum) with a 1% latex suspension containing 0.489 #m latex particles coated with affinity-purified antibody at a ratio of 20 #g/mg latex. The agglutination was performed on a glass slide in a moist chamber at room temperature with 45 min. incubation. This t...

A new species of Physarum (Myxomycetes), Physarum atacamense is described in this paper, and details are provided on its life cycle as observed in spore-to-spore culture in agar. The new species was collected during studies of the Atacama Desert in Chile. It has been collected directly in the field and isolated in moist chamber cultures prepared with material from an endemic cactus. The combina...

The meningococcus is not a "microaerophile." It grows equally well in atmospheres containing from 15 to 40 per cent oxygen. If small amounts of carbon dioxide affect the growth of the meningococcus on an artificial medium it is by changing the reaction of the medium, not by slightly reducing the oxygen tension of the surrounding air. The fallibility of titrating the total acidity of a medium is...

The increased use of donor epithelium in keratoplasty for severe corneal disease has prompted an investigation of epithelial viability during midterm storage. Glycogen, ATP, and ADP have been used as indicators of the metabolic state of epithelial cells. These substances have been measured after conventional moist-chamber storage at 4 degrees C. for 1, 2, and 12 days and after immersion at 4 de...

Demodex folliculorum has been incriminated in the development of blepharitis although much controversy persist. Some authors suggest that Demodex is a direct pathogen in chronic palpebral conditions while others consider the saprophyte to be innocuous to skin. We conducted a prospective study of eyelashes in 48 patients with blepharitis (totally 96 eyes) and 48 healthy persons (totally 96 eyes)...

The agglutination was performed on a glass slide in a moist chamber at room temperature with 45 min. incuba...

The germination of Ferula ovina seeds faces certain problems. The present research was designed to study the promotion of the germination of Ferula ovina seeds by moist-chilling and GA3 applications. The results showed that Ferula ovina seeds display an endogenous dormancy that can be released by moist-chilling treatment for a certain period. In this respect, the best treatment was moist-chilli...
