Characterization of Petroleum Residues with Varying Cutting Depth and Corresponding Vacuum Distillates Derived from Laboratory Deep-Vacuum Fractionation of Unconventional Heavy Oil for an Instructive Utilization Guideline

23-Jan-2017 | Peng Xue; Shiguang Fan; Xuebing Wang; Kun Chen; He Liu; Wei Xia; Aijun Guo; Zongxian Wang, Energy & Fuels, 2017

Petroleum residues with varying cutting depth and corresponding vacuum distillates have been prepared from laboratory deep-vacuum fractionation using unconventional heavy oil (UHO) originated from Venezuela first. They are then sequentially characterized by general analysis, process analysis, and ...

Theoretical Investigation of the Mechanisms of ERK2 Enzymatic Catalysis

29-Sep-2016 | Mikita M. Misiura; Anatoly B. Kolomeisky, Journal of Physical Chemistry B, 2016

ERK2 are protein kinases that during the enzymatic catalysis, in contrast to traditional enzymes, utilize additional interactions with substrates outside of the active sites. It is widely believed that these docking interactions outside of the enzymatic pockets enhance the specificity of these ...

A new approach for kLa determination by gassing‐out method in pneumatic bioreactors

26-Feb-2016 | Marcel O Cerri, Mateus N Esperança, Alberto C Badino, Marcelo PA Ribeiro, Journal of Chemical Technology & Biotechnology, 2016

ABSTRACT BACKGROUND Determination of the volumetric oxygen transfer coefficient (kLa) is very important for bioreactor design and process analysis. Among all the methods available, the gassing‐out technique is one of the simplest and most widely used for this task. However, this method is ...

Direct Dynamic Kinetic Analysis and Computer Simulation of Growth of Clostridium perfringens in Cooked Turkey during Cooling

23-Jan-2016 | Lihan Huang, Bryan T. Vinyard, Journal of Food Science, 2016

Abstract This research applied a new 1‐step methodology to directly construct a tertiary model that describes the growth of Clostridium perfringens in cooked turkey meat under dynamically cooling conditions. The kinetic parameters of the growth models were determined by numerical analysis and ...

Process Analytical Utility of Raman Microspectroscopy in the Directed Differentiation of Human Pancreatic Insulin-Positive Cells

20-Oct-2015 | Stanislav O. Konorov; H. Georg Schulze; Blair K. Gage; Timothy J. Kieffer; James M. Piret; Michael W. Blades; Robin ..., Analytical Chemistry, 2015

Continued advances toward cell-based therapies for human disease generate a growing need for unbiased and label-free monitoring of cellular characteristics. We used Raman microspectroscopy to characterize four important stages in the 26-day directed differentiation of human embryonic stem cells ...

Sensors, Vol. 15, Pages 18270-18286: A Comparative Study on the Suitability of Smartphones and IMU for Mobile, Unsupervised Energy Expenditure Calculi

27-Jul-2015 | Ruiz-Zafra, Angel ; Orantes-González, Eva ; Noguera, Manuel ; Benghazi, Kawtar ; Heredia-Jimenez, Jose, Sensors, 2015

The metabolic equivalent of task (MET) is currently the most used indicator for measuring the energy expenditure (EE) of a physical activity (PA) and has become an important measure for determining and supervising a person’s state of health. The use of new devices which are capable of measuring ...

Molecules, Vol. 20, Pages 4007-4019: Image Monitoring of Pharmaceutical Blending Processes and the Determination of an End Point by Using a Portable Near-Infrared Imaging Device Based on a Polychromator-Type Near-Infrared Spectrometer with a High-speed and High-Resolution Photo Diode Array Detector

03-Mar-2015 | Murayama, Kodai ; Ishikawa, Daitaro ; Genkawa, Takuma ; Sugino, Hiroyuki ; Komiyama, Makoto ; Ozaki, Yukihiro, Molecules, 2015

In the present study we have developed a new version (ND-NIRs) of a polychromator-type near-infrared (NIR) spectrometer with a high-resolution photo diode array detector, which we built before (D-NIRs). The new version has four 5 W halogen lamps compared with the three lamps for the older ...
