background and aims. the aim of this study was to compare the effectiveness of adjunctive photodynamic therapy (pdt) in the treatment of aggressive periodontitis. materials and methods. a total of 24 patients with clinical diagnosis of aggressive periodontitis received scaling and root planing (srp) for periodontal treatment. in a split-mouth design study, the teeth of one quadrant of each arch...

background: boric acid (ba) is commonly used as pesticide, disinfectant and wood preservative. its ingestion can cause serious organ damages resulting in death. case report: a 19 year old man was found dead with two empty packs of ba tablets in vicinity of his body. on autopsy examination, brownish stains along with right angle of mouth and right nostril were found. stomach was damaged with hem...

An experimental study of interactions between hydration and early drying was carried out on a mortar with GGBFS volume as high the OPC volume. 1 day after casting, subjected to 6-month unidirectional in natural surrounding conditions laboratory. At end exposure period, Portlandite content, water porosity pore size distribution were found be not uniform along material. When approaching exposed s...

In the recent years, the biophysical properties and presumed physiological role of aquaporins (AQPs) have been expanded to specialized cells where water and solute exchange are crucial traits. Complex but unique processes such as stomatal movement or pollen hydration and germination have been addressed not only by identifying the specific AQP involved but also by studying how these proteins int...

Terpinen–4–ol is a natural product with wide application in the fragrance and agrochemical industry, currently extracted from tea tree oil or synthesized either base–promoted rearrangement of 1,4–cineol acid–catalyzed hydration limonene. However, these synthetic processes, based on aggressive, unrecoverable homogeneous reagents, are non–selective give significant amounts isomers, which severely...

The major hydraulic phase in all the calcium aluminate cements including ciment fondue is CA (CaAl2O4). Once hydrated, it starts to form the hexagonal crystals of CAH10 and C2AH8 that depending on the time and temperature of hydration convert to the cubic crystals of C3AH6 and AH3. The nature, sequence, ...

in this study the effect of nano meter size zro2 particles on the microstructure, densification and hydration resistance of magnesite –dolomite refractories was investigated. 0, 2, 4, 6 and 8 wt. % zro2 particles that were added to magnesite –dolomite refractories containing 35 wt. % cao. the hydration resistance was measured by change in the weight of specimens after 72 h at 25℃ and 95% relati...

BACKGROUND Numerous laboratory based studies have documented that aggressive hydration strategies (approximately 1-2 litres/h) are required to minimise a rise in core temperature and minimise the deleterious effects of hyperthermia on performance. However, field data on the relations between hydration level, core body temperature, and performance are rare. OBJECTIVE To measure core temperatur...
