The aim of this investigation was to improve the storage stability and survival rate of intravesical BCG product, manufactured with an attenuated strain of Mycobacterium bovis (Pasteur strain 1173P2 of BCG) in the presence of sodium glutamate. Formulations with various concentrations of trehalose (a known protectant) were developed as liquid and lyophilized forms. Formulations were evaluated by...

the objective of this research was to study the drying characteristics of powderedagricultural residues. drying experiments of wheat straw (triticum aestivum) wereconducted at four temperatures of 50, 60, 70, and 80°c by a thermogravimetric analyzer.drying temperature had a significant effect on the moisture change and drying time.there was no constant drying rate period, but a short rising rat...

Calcium carbonate is a versatile mineral with diverse industrial applications. Drying is a necessary processing step in preparation of calcium carbonate product. Deep knowledge of drying kinetics is required in order to design an appropriate dryer. The main aim of the present study was to investigate the drying kinetics of calcium carbonate, experimentally. Thirteen empirical correlations with ...

in recent years immense interest has been focused on the use of solar dryers especially when taking into consideration economical and ecological aspects and increasing in fuel costs. the aim of this study was to compare the qualitative factors of raisins made by five different drying methods. at the first step, pretreatments were applied to grapes (var. sultanas) and then the grapes were dried ...

The main purpose of this paper is to assess the impact of the geometry and size of the aggregate, as well as the drying temperature on the compressive strength of the ordinary concrete. To this end, two aggregates with sharp and round corners were prepared in three different aggregate sizes. After preparing concrete samples, the drying operations were carried out in the vicinity of room tempera...

vacuum drying of salicornia herbacea l. was performed at different drying temperatures (50, 60, 70, and 80c) to evaluate the drying characteristics and the effect of drying temperatures on the quality of salicornia. as the drying temperature increased, the drying time decreased significantly (p< 0.05). the drying rate decreased with decrease in moisture content and increase in drying time. on ...

BACKGROUND Hair dryers are commonly used and can cause hair damage such as roughness, dryness and loss of hair color. It is important to understand the best way to dry hair without causing damage. OBJECTIVE The study assessed changes in the ultra-structure, morphology, moisture content, and color of hair after repeated shampooing and drying with a hair dryer at a range of temperatures. METH...

the effect of pre-treatments in combination with hot air, vacuum and hot-a microwave drying methods the progress of the drying process, and textural, and colour and rehydration rate on button mushroom (agaricus bisporus) slices were investigated. in this work, one of the following methods: hot air, vacuum drying or microwave-assisted convective drying and also different pre-drying treatments, v...

objective: potato is the fourth important food crop after wheat, rice and maize. shrinkage  of  food  materials  has  a negative  consequence  on  the  quality  of  the dehydrated product. the main objective pursued in this paper is to investigate the shrinkage amount of potato slices during drying process using vacuum-infrared method. methods: in this work, the effect of the infrared radiation...
