corophium volutator (pallas) has been recommended by the paris commission as one of the standard species for testing chemical used in offshore oil and gas exploration/production. in the present study, gut contents of corophium volutator have been analysed by electron probe microanalysis (epma) for baso4 and other heavy metal impurities after exposure tto spiked sediments following a standard as...

purpose : to report a patient with retained broken probe tip in the false passage site after nasolacrimal duct (nld) probing case report : a 18-month-baby with epiphora and a nontender mass in the site of lacrimal sac was visited in clinic. she had a history of probing six months ago by another ophthalmologist. the probing was repeated successfully but the mass size didn’t change. the mass was ...

background: the purpose of this study was to compare the effi cacy of endovac irrigation system and side-vented closed ended needle (max-i probe) in removing smear layer from root canals at 1 mm and 3 mm from working length using protaper rotary instrumentation. materials and methods: a total of 50 freshly extracted maxillary central incisors were randomly divided into two groups after complete...

Abstract The newest method to maintain better bioavailability of antioxidant compounds in the human digestive process is encapsulation using liposomes. liposomes used were lecithin from soybean seeds and L-α-Phosphatidylcholine. Furthermore, curcumin β-carotene encapsulated soy SC-CO2 with 100% ethanol, aquadest 50% v/v ethanol at 50°C, 60°C, 70°C pressure 15 MPa, 20 MPa 25 by ultrasonication f...

Using a mobile photothermal probe we show that it is possible to detect rapidly different type of cracks (emerging ones or not), their width being a few micrometers and their depth being some hundredths of micrometers.

The degradation of poly (vinyl pyrrolidone) (PVP) by means of ultrasound irradiation and itscombination with heterogenous photocatalysis (TiO2 nanoparticles) was investigated. Emphasiswas given on the effect of additive on degradation rate constants. 24 kHz of ultrasoundirradiation was provided by a sonicator, while an ultraviolet source of 30 W was used for UVirradiation. To increase the effic...
