With stability testing, pharmaceutical industry inspects the quality of drug substances and drug products as per the guidelines outlined by US Food and Drug Administration and International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use to make sure that they retained the quality over the period of time.
Freeze-drying is used extensively to preserve insects for the purposes of consumption. Whole freeze-dried insects are sold as exotic pet food, bird feed, fish bait, and increasingly for human consumption. [28] [29] Powdered freeze-dried insects are used as a protein base in animal feeds, and in some markets, as a nutritional supplement for ...
A thermal shift assay (TSA) measures changes in the thermal denaturation temperature and hence stability of a protein under varying conditions such as variations in drug concentration, buffer formulation (pH or ionic strength), redox potential, or sequence mutation. The most common method for measuring protein thermal shifts is differential ...
The mechanical stability, freeze-thaw stability and shelf-life of paints are all improved by the addition of surfactants. The addition of surfactants to paint also allow the paint to coat a surface more easily because surfactants increase the wetting of a solution.
Concrete produced by carbonation curing also shows superior performance when subject to physical degradations, e.g., freeze-thaw damage, particularly due to a pore densification effect enabled by the precipitation of carbonation products [38] The vast majority of CO 2 emissions from concrete come from cement manufacturing. Therefore, methods to ...
Despite its durability, maintenance, repair techniques, and abrasive cleaners can cause damage to the concrete. Environmental factors are the main cause of concrete deterioration, mainly the freeze-thaw cycles that allow moisture to be absorbed into the concrete, causing cracks, erosion, corrosion, deflection, and spalling.
It is anyway opportune to close up and cement any cracks in the rock to prevent pressure caused by water during the freeze-thaw cycles from producing progressive breaking in the reinforcement system set up. To this purpose a procedure is provided for of: cleaning out and washing of the cracks; plastering of the crack;
