The Effects of Relative Humidity on the Flowability and Dispersion Performance of Lactose Mixtures

The flowability and dispersion behavior are two important physicochemical properties of pharmaceutical formulations for dry powder inhalers (DPIs). They are usually affected by the environmental conditions, such as temperature and relative humidity (RH). However, very few studies have been focused on the relationship between the two properties and their dependence on RH during storage. In this ...

Response of air-borne species of Pasteurella to artificial radiation simulating sunlight under different conditions of relative humidity.

The bactericidal effect of sunilight was demonstrated as early as 1878 by Downes and Blunt who reported that culture media exposed to sunlight for several hours remained sterile, wlrhile corresponding portions of the same media which were allowed to stand in shaded portions of the same room became contaminated. Tizzoni and Cattani (1891) and Wesbrook (1896) reported the killing of Clostridium t...

Effect of urea and nitrapyrine on quantitative and qualitative characteristics of barley cultivars (Hordeum vulgare L.) under different tillage conditions

Tillage methods are among the most successful factors in agriculture that have a significant impact on the quality and quantity of agronomic plants. To evaluate different tillage methods and urea fertilizer with nitrapyrin on total chlorophyll content, grain protein, yield, and yield components of two barley (Hordeum vulgare L.) cultivars, an experiment was conducted as split factorial in the r...

Promoters maintain their relative activity levels under different growth conditions

Most genes change expression levels across conditions, but it is unclear which of these changes represents specific regulation and what determines their quantitative degree. Here, we accurately measured activities of ~900 S. cerevisiae and ~1800 E. coli promoters using fluorescent reporters. We show that in both organisms 60-90% of promoters change their expression between conditions by a const...

Demonstration of Aerosol Property Profiling by multi-wavelength Lidar under Varying Relative Humidity Conditions

The feasibility of using a multi-wavelength Mie-Raman lidar based on a tripled Nd:YAG laser for profiling aerosol physical parameters in the planetary boundary layer (PBL) under varying conditions of relative humidity (RH) is studied. The lidar quantifies three aerosol backscattering and two extinction coefficients and from these optical data the particle parameters such as concentration, size ...
