[1] The sensitivity of microwave brightness temperatures at the frequencies between 89 and 190 GHz to surface emissivities and hydrometeors in a tropical deep convective cloud system is investigated by simulations, using the Goddard Cumulus Ensemble model data of a simulated oceanic tropical squall line as input for a radiative transfer model. It is found that only the window channel at 89 GHz ...

It was demonstrated that the combination of the almost water insoluble active pharmaceutical ingredient (API) ibuprofen with the biocompatible 1-ethanol-3-methylimidazolium [C2OHMIM] cation of an ionic liquid (IL) leads to a highly water miscible IL-API with a solubility increased by around 5 orders of magnitude. Its phase transformations, as crystallization and glass transition, are highly sen...

The Ka-band radars are particularly suited for cloud droplets and small rain drop regime measurements, by their capability to penetrate through rainand snow-falls and to detect small hydrometeors. Traditionally three moments of Doppler spectra are used as basis to retrieve microphysical cloud parameters, e. g. characteristic particle size (Gossard, 1997), liquid water content (Liao, 1994) and t...

Based on Canadian Satellite (RADARSAT) synthetic aperture radar (SAR) images and simulations from a radar-backscattering model, we determined that conventional wet snow-mapping algorithms should perform optimally for a snowpack with a liquid-water content 3%, at low incidence angle ( = 20–30 ) and for a rather smooth surface (rms height ≤ 2.1 mm).

A model is presented of a polymer electrolyte fuel cell including slow transient effects of liquid water accumulation and evaporation in gas diffusion electrodes GDEs and gas channels. The model is reduced dimensionally, coupling a one-dimensional 1D model of gas and coolant channel flow to 1D models of transport through the membrane electrode assembly MEA and bipolar plates. An asymptotic redu...

The cloud drop effective radius, Re, is one of the most important parameters in calculations of cloud radiative properties. Numerous formulations of the effective radius have been developed for use in numerical models (see, e.g., review in Gultepe et al. 1996); however, to the best of our knowledge, they all were designed for non-drizzling clouds. The objective of this paper is to derive a para...

In this study, the feasibility of ternary mobile phases was examined in a high-performance liquid chromatography (HPLC)-based analysis of carbonyl compounds (CCs). To test the performance of different ternary phases, the liquid phase standards containing a 15 aldehyde/ketone-DNPH(o) mix were analyzed through a series of five-point calibration experiments. For this comparison, three types of ter...

The aerosol survival in air was determined for Pasteurella tularensis live vaccine strain (LVS) as a function of relative humidity (RH). Three different preparations of bacteria were used: (i) liquid suspension of P. tularensis LVS in spent culture medium; (ii) powders of P. tularensis LVS freeze-dried in spent culture fluid; (iii) P. tularensis LVS freeze-dried in spent culture fluid and then ...

abstract polycyclic aromatic hydrocarbons (pahs) are classified as persistent and carcinogenic organic pollutants. pahs contamination has been reported in water. many of relevant regulatory bodies such as eu and epa have regulated the limit levels for pahs in drinking water. in this study, 13 priority polycyclic aromatic hydrocarbons (pahs) were determined in tap water samples of tehran and wat...
