precise localization of the third molars in relation to the inferior alveolar nerve canal is critical from a clinical point of view and strongly affects the surgical treatment outcome. recently, by using three-dimensional modeling software, the relationship of third molar root apices and inferior alveolar nerve canal can be better understood. in this study, the spatial relationship of two surgi...

The density of 15-crown-5 ether (15C5) solutions in the mixtures of N,N-dimethylformamide (DMF) and water (H2O) was measured within the temperature range 293.15-308.15 K using an Anton Paar oscillatory U-tube densimeter. The results were used to calculate the apparent molar volumes (VΦ ) of 15C5 in the mixtures of DMF + H2O over the whole concentration range. Using the apparent molar volumes an...

Kojima K, Mckinley K, Donohue P, Sigal Y. The high prevalence of inappropriate feeding among infants presenting with an apparent life-threatening event. Turk J Pediatr 2017; 59: 304-310. Although there are anecdotal reports of a link between inappropriate feeding and an apparent life-threatening event (ALTE), previous studies have not examined this association in a cohort of affected infants. T...

density (r/g cm-3) and viscosity (h/10-2gcm-1s-1=1centipoise,cp) of guanosine monophosphate (gmp) and adenosine triphosphate (atp) referred to as nucleotide, and 2-deoxy adenosine (doa) and thymidine (tmd) as nucleoside along with their integral furanose sugar, 2-deoxy ribose (dor) from 0.0004 to 0.0014mol kg-1 solution have been measured at 288.15, 293.15 and 298.15k at atmospheric pressure. t...

Knowledge space theory was used for mapping students’ knowledge structures in calculating density, mass-percent, molar mass and molar volume. Data were collected among the 9-10 graders (age 15-16) at two different secondary grammar schools. Students’ responses were evaluated in a binary fashion and were used for determining knowledge structures with a systematic trial-and-error process using χ ...

From measurements of the surface tension, density, viscosity and light scattering of aqueous solutions of methanol, ethanol and propanol at 293 K, their activity in the surface monolayer, surface excess concentration, and apparent and partial molar volume were determined. The surface excess concentration of alcohols at the water-air interface was determined from the Gibbs equation by using both...

In this research, the effects of important parameters, including the molar ratio of acetic acid to sulfur(S) , sonication time, temperature, and hydrogen the molar ratio of peroxide to sulfur on the performance of ultrasound-assisted oxidative desulfurization were studied using the response surface method (RSM). To this end, a model fuel containing n-decane and dibenzothiophene at a concentrati...

Abstract In this article, detailed physicochemical characterization of ethylene glycol and caffeine + mixtures is performed based on density, viscosity refractive indices measurements in temperature range from (288.15 to 343.15) K. The apparent molar volume (V?), at infinite dilution (V?o), Masson's experimental slope (Sv), limiting expansibility, (E?o), B-coefficient, thermodynamical parameter...

there are a number of techniques available to estimate saturated-liquid molar or specific volumes or densities of liquids. in this study, a new empirical correlation is presented to calculate volume of saturated liquids as a function of critical volume, reduced temperature and acentric factor. an optimization algorithm is utilized to obtain unknown parameters of this correlation by fitting them...
