In this study, effects of multi walled carbon nanotubes and temperature on rheological behavior of engine oil (10W40) have been examined. For this purpose, the experiments were carried out in the temperature range of 5-55°C for several suspensions with solid volume fractions of 0.025%, 0.05%, 0.1%, 0.25%, 0.5% and 0.75%. The viscosity of all samples was measured in the shear rate range of 666s-...

objective: the present study assessed the association of size, axial angulation, developmental stage and bud position of the mandibular third molar with the second molar impaction in patients with mandibular second molar impaction. methods: in this descriptive-analytical study (case-control design), dental records of 5,420 patients in the age range of 12-15 years who underwent orthodontic treat...

The buccal fat pad (BFP), is an adipose tissue located in the cheek, with complex morphology. Oral bichatectomy a frequent aesthetic procedure possible complications. Our objective was to determine volume and its relationship upper 2nd molar facial artery (FA). A cross-sectional, observational study performed. Computed tomography used obtain 3D images volume, length, width. Distances from each ...

A systematic study of the modification of papain (its thiol group protected as a disulphide with mercaptoethanol) by N-bromosuccinimide, showed that 2 molar equiv. modified tryptophan-69 and 4 molar equiv. modified tryptophan-69 and -177. The Michaelis parameters for the catalysed hydrolysis of N-benzyloxycarbonylglycine p-nitrophenyl ester by these modified enzymes were determined. The enzymic...

The densities of 12 melts in the Na20-FeO-FezOrSi02 system have been determined in equilibrium with air, in the temperature range of lOOO15OO”C, using the double bob, Archimedean technique. Ferrous iron determinations of 100-200 mg samples, “dip” quenched from high temperature, indicate that all the melts investigated were highly oxidixed under these experimental conditions. “Fe Massbatter spec...
