Application of the Principles of Green Chemistry for the Development of a New and Sensitive Method for Analysis of Ertapenem Sodium by Capillary Electrophoresis

open access: yesInternational Journal of Analytical Chemistry, Volume 2019, Issue 1, 2019., 2019
An innovative method is validated for the analysis of ertapenem sodium by capillary electrophoresis using potassium phosphate buffer 10 mM pH 7 and 15 kV voltage, in the concentration range of 70 to 120 μg mL−1. Ertapenem had a migration time of 3.15 minutes and the linearity curve was y = 2281.7 x ‐ 24495 with a R2 = 0.9994. Thus, we propose a routine

Influence of the Temporomandibular Joint in the Estimation of Bone Density in the Mandible through a Bone Remodelling Model

open access: yesMathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018
The temporomandibular joint (TMJ) plays a key role in the distribution of stresses in the mandible during mastication and consequently in the distribution of bone density, due to the interconnection between both variables through bone remodelling. Two finite element models of the mandible were compared to study the influence of the redistribution of ...
