Abstract The (early) hydration mechanisms of two different binder systems used for shotcrete were investigated: the so far almost unexplored low sulfate (spray binder), in field dry-mix shotcrete; and ordinary Portland cement, accelerated by aluminum sulfate, widely wet-mix shotcrete. basis fast setting spray is rapid dissolution C 3 A subsequent formation flaky CO -AFm phases. Thereby induced ...

• Sitz Baths — Fill your tub with about 6 inches of warm water and sit in the tub for 10 to 15 minutes at least 2 to 3 times each day. Th e warm water increases the fl ow of blood to the perineum, which helps the area heal. • Rosemary Tea — Make a tea with dried rosemary leaves by pouring very hot water over about 3 tablespoons of the leaves. You can buy these leaves in bulk at many grocery sto...

Inhalation of pirfenidone is one the possible methods for effective treatment idiopathic pulmonary fibrosis. In this study, we attempted to prepare inhaled dry powder through reasonable design precursor formulation and parameter adjustment spray drying process. The mechanism polyvinyl alcohol (PVA) polymer as surfactant used assist dissolution in water, instead using organic solvents (such etha...

Pulmonary administration of protein and peptide drugs using inhaled dry powder particles is an interesting alternative to parenteral delivery. The stabilisation of these molecules is essential to the maintenance of biological activity in such inhalation formulations. Here salmon calcitonin (sCT) was co-spray dried with linear or branched PEG (L-PEG and B-PEG) and PVP in order to formulate aeros...

U.S. beef slaughter facilities are required to use a carcass intervention treatment to reduce contamination by Escherichia coli O157:H7. Very small beef slaughter operators generally are unable to carry out challenge studies to validate intervention treatment effectiveness, and in-plant pathogen challenge studies are not permitted. The objective of this study was to evaluate the effectiveness, ...

Nowadays, several medicinal plants are used to produce pharmaceuticals. Nonetheless, development of phytopharmaceutical has intrinsic technological challenges [1]. Concerning to liquid and dry plant extracts, the latter possess many advantages over the former. The chemical and microbiological stability are greater in dry extracts. However, the dry extracts usually show poor physicomechanical pr...
