Crude oil characterization using TGA-DTA, TGA-FTIR and TGA-MS techniques

Journal of Petroleum Science and Engineering, 2017
© 2016 Elsevier B.V.In this research, combustion characterization and kinetics of four different origin crude oil samples were determined using thermogravimetry - differential thermal analysis (TGA-DTA) and thermogravimetry - Fourier transform infrared (TGA-FTIR) and thermogravimetry – mass spectrophotometry (TGA-MS) techniques. In the TGA-DTA analysis

Echocardiographic differences between D‐TGA and L‐TGA in adult patients

Echocardiography, 2020
AbstractTransposition of the great arteries (TGA) is a common cardiac malformation in which the great arteries are discordant relative to the ventricles. The two common forms of transposition include D‐TGA, which presents with cyanosis early in life, and L‐TGA, which on the other hand, may permit survival to adulthood without being diagnosed in ...

TGA and macro-TGA characterisation of biomass fuels and fuel mixtures

Fuel, 2011
The thermal behaviour of selected biomass fuels and mixtures as wood, demolition wood, coffee waste and glossy paper was investigated using a thermogravimetric analyzer (TGA) and a macro-thermobalance (macro-TGA). A kinetic model, involving first-order independent parallel reactions, was applied to results obtained from pyrolysis TGA experiments.

Study of the degradation of a thermoset system using TGA and modulated TGA

Progress in Organic Coatings, 2005
The degradation of the epoxy system diglycidyl ether of bisphenol A (this epoxy is also named DGEBA (n = 0), where n indicates the number of structural units inside the molecule) cured with hardener metaxylilene diamine (m-XDA) was studied on a dynamic basis using TGA and modulated TGA techniques under a nitrogen atmosphere with 5% O 2.

TGA-IVS and TGA-VSD Seen Late

2016
Late referral of patients with complete transposition of the great arteries (TGA) is common in developing countries. However, outcomes of these patients who undergo surgical correction late remain unclear. To obtain favorable outcomes in these “late” patients, understanding of the surgical indications, management and specific surgical techniques is ...

Assessment of the thermal pyrolysis characteristics and kinetic parameters of spent coffee waste: a TGA-MS study

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2020
The present study aimed to investigate the pyrolysis characteristics and kinetics of spent coffee waste (SCW) at different heating rates (5–40 °C/min) at a temperature ranging from 30 to 800°C in a thermogravimetric analyzer (TGA).

Patients with Surgical Corrected TGA or Congenital Corrected TGA Supported with Durable VAD

The Journal of Heart and Lung Transplantation, 2019
Purpose We aimed to analyze durable VAD support of an anatomical right ventricle as systemic ventricle (any patients born with a transposition of the great arteries (TGA); either ccTGA or surgical corrected TGA using Mustard/Senning procedure).

Thrombin Generation Assays (TGAs)

2017
In recent years, there has been a revival of interest in a time-honored tool of the clotting trade: the thrombin generation curve or thrombin generation (TG) assay (TGA) as we now call it. Thrombin generation is a key coagulation process that determines the extent of a hemostatic plug or a thrombotic process. The recent development of newer tests based

History of TGA

2017
This chapter considers the history of TGA. This may be dated from the first use of the term “transient global amnesia” by Fisher and Adams in their publications of 1958 and 1964, but the characteristic clinical features had been described earlier than this under different appellations, in both the English (“episode of confusion with amnesia”) and ...
