Standard addition strips were prepared for the quantitative determination of caffeine in different beverages by electrostatic spray ionization mass spectrometry (ESTASI-MS). The gist of this approach is to dry spots of caffeine solutions with different concentrations on a polymer strip, then to deposit a drop of sample mixed with an internal standard, here theobromine on each spot and to measur...

Microencapsulation of plant-beneficial bacteria for use as biopesticides is a growing area interest in the search alternatives to harmful chemical pesticides. In this study, we assessed microencapsulation Gram-negative, non-spore-forming bacterial strain Collimonas arenae Cal35 novel cross-linked alginate microcapsules (CLAMs) formed by spray-drying, and matrix shell (CLAMshell) particles fluid...

this study was carried out to examine the effects of kaolin spray for reducing the adverse effects of high radiation and temperature, especially on fruit sunburn in apple. treatments were four concentration of kaolin (0, 2, 4, and 6%) and two important and commercial apple cultivars in fars province; ‘golden delicious’ and ‘starking delicious’. trees physiological parameters, fruit sunburn and ...

OBJECTIVE This randomised, double-blind, parallel group phase II/III study with adaptive two-stage design and interim analysis compared the efficacy and tolerability of spray (containing a Salvia officinalis fluid extract) against placebo in the treatment of patients with acute viral pharyngitis. - STUDY PARTICIPANTS in two study parts, a total of 286 patients with subjective and objective ev...

The pulmonary route of delivery offers a potential alternative to parenteral administration of peptides and proteins. Protection of protein structure is essential in both processing and storage of the final formulation. Sugars, such as trehalose and raffinose, have been employed to act as protein stabilisers. Optimisation of the aerodynamic characteristics of microparticles in dry powder inhale...

For particles to be useful medicinal aerosols, not only their aerodynamic diameter has to be on the order of a few micrometers but also they have to be chemically and physically stable. Manufacture of respirable particles is a technical challenge because as particles are reduced in size by conventional milling techniques, their cohesiveness greatly increases and physical and chemical stability ...

An adiabatic dry saturated steam compression process with inner evaporative spray cooling in screw compressors for steam heat pump systems is studied. Thermodynamic model and simulation of this variable-mass compression process are devised. Differential equations are formulated and used to calculate the amount of liquid injected and the work to drive the compressor on the basis of simplificatio...

A diploid potato (Solanum tuberosum) mutant called droopy wilts easily. Excised leaves of the mutant lost weight, and hence water, more rapidly and had many more open stomata than leaves of a normal sibling. Further, the stomata of abnormal plants remained open in wilted leaves. When the stomata of the abnormal mutant were closed by a chemical spray, its excised leaves lost water no more rapidl...

Nitroglycerin is the oldest and most commonly prescribed short-acting anti-anginal agent; however, despite its long history of therapeutic usage, patient and health care provider education regarding the clinical benefits of the short-acting formulations in patients with angina remains under-appreciated. Nitrates predominantly induce vasodilation in large capacitance blood vessels, increase epic...

Agricultural lands are gradually being contaminated by heavy metals (HMs) obtained from urbanization and human activities. Lead (Pb) is one of the major easily enters into food cycle causes different health abnormalities. So elimination this dangerous metal surface water crucial in regard phyto-extraction based phytoremediation an environmentally safe procedure. Again, removal process can be am...
