Vacuum and temperature effects on moisture content, water vapor permeability (WVP), color (L, a, b, and DE), tensile strength (TS), elongation (E), and total soluble matter (TSM) of soy protein isolate (SPI) films were examined. SPI films were cured at 60, 72.5, or 85 °C and at 101.3, 81.32, or 61.32 kPa for 24 h. As a result of heat-curing moisture content, WVP, E, and TSM decreased, and total...

The cold in-place recycling (CIPR) is a process where the existing bituminous pavement is recycled without application of heat. In CIPR process the scarified material from the existing pavement is crushed to the required gradation and binder in cold form (emulsion or cutback or foamed bitumen) is added. Externally acquired Reclaimed Bituminous Pavement (RBP) or fresh aggregates are also added d...

Introduction Vulcanization refers to a specific curing process of rubber involving high heat and the addition of sulfur or other equivalent curatives. It is a chemical process in which polymer molecules are linked to other polymer molecules by atomic bridges composed of sulfur atoms or carbon-to-carbon bonds. The end result is that the springy rubber molecules become cross-linked to a greater o...

A new study in the Journal of Alzheimer's Disease finds a strong link between some food preservatives and an increased risk of death from Alzheimer's, Parkinson's and diabetes. These food additives have previously been linked with several different types of cancer, including prostate, colon and rectum. Sodium and potassium nitrates are used in the processes of salting, pickling and curing foods...

The temperature distribution in human body regulates variety of biological mechanism. Human Skin is a very complex structure and abnormality in temperature of various layer of skin play important role for curing and treatment diseases like tumor, cancer etc. The eight layers of human skin namely stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, stratum germinativum, papill...

A typical epoxy assembly process is to blend the two parts (resin and hardener), deposit the liquid on a substrate, attach a second part, and immediately cure with time and / or heat. But in many cases it may be beneficial to separate the blending / depositing process from the curing process. This could be driven by in-plant logistics, or the need to run each process in separate facilities with...

OBJECTIVE: To determine the frequency of patients with various anatomical forms hard palate for complete denture fabrication and to compare mean distortion in heat cure base polymer millimetres different forms. METHODOLOGY: Informed consent was taken from total seventy six divided into low medium Dental casts were prepared alginate impression poured type III stone reference point R marked on de...

Pellets containing active ingredients were coated with water-insoluble powders, i.e. hydrogenated caster oil (Lubliwax (WAX)) and magnesium stearate (Mg-St). The influences of the structural difference of the sustained release layer and curing conditions on the drug release rate were investigated. Sodium valproate (VP-Na) was used as a highly water-soluble model drug. Drug release profiles were...

Thermal integrity profiling (TIP) is a common non-destructive technique to evaluate the quality of construction piles by analysing temperature fields due heat hydration from freshly cast concrete piles. For this process be accurate, reliable model required. This paper proposes practical and simple calibrate four-parameter for prediction hydration. has been shown able reproduce evolution measure...
