The aim of this study is to examine the behaviour melon seed pyrolysis and calculate its kinetic parameters along with thermodynamic properties. thermogravimetric analysis experiments were conducted from ambient temperature 800°C under nitrogen atmosphere at heating rates 5, 10, 20 40°C/min. It was determined that process underwent through four stages where second third active stages. Kinetic c...

The DSC method has been employed to monitor the kinetics of reticulation of aqueous polyurethane systems without catalysts, and with the commercial catalyst of zirconium (CATXC-6212) and the highly selective manganese catalyst, the complex Mn(III)diacetylacetonemaleinate (MAM). Among the polyol components, the acrylic emulsions were used for reticulation in this research, and as suitable reticu...

Multiple types of hydrogen trapping sites in advanced high-strength steels (AHSS) are often experimentally characterized by means thermal desorption spectroscopy (TDS). The evaluation is regularly based on the peak deconvolution procedure combined with Kissinger's theory, which provides distinctive energies at microstructural defects. However, published literature non-conclusive and from time t...

Thermogravimetric studies of chitin and chitosan in air atmosphere were carried out at six rates of linear increase of the temperature. The kinetics and mechanism of the thermal decomposition reaction were evaluated from the TG data using recommended from ICTAC kinetics committee isoconversional calculation procedure of Kissinger-Akahira-Sunose, as well as 27 mechanism functions. The values of ...

The genus Miloderes Casey, 1888 is reviewed and three new species are described. The genus now has eight valid species: M. amargosensis sp. nov., M. mercuryensis Tanner, M. nelsoni Kissinger, M. panamintensis sp. nov., M. setosus Casey, M. tingi Tanner, M. ubehebensis sp. nov. and M. viridis Pierce. Miloderes allredi Tanner, 1974 is a new junior synonym of M. viridis Pierce, 1910. The relations...

p-Aminomethylbenzenesulphonamide (I) was first described by Miller, Sprague, Kissinger & McBurney (1940), and is used in therapy as its hydrochloride, Ambamide (formerly Marfanil). Its antibacterial properties were studied by Klartr (1941) who found it to be less active than sulphanilamide against streptococci, but more active against anaerobic bacteria (cf. Schoop & Stoltz, 1941 Hamre, Walker,...

Trypanosoma cruzi trypomastigotes, but not epimastigotes, are normally resistant to the lytic effects of complement from vertebrate hosts susceptible to infection. This resistance facilitates parasite survival and infectivity. During the course of chronic infections, however, the vertebrate hosts produce antibodies that render the trypomastigotes sensitive to lysis, primarily via the alternativ...

Abstract Rice husk is abundantly available biomass in Indonesia and it can be a potential source of high-value energy source. In the present work, pyrolysis rice was subjected to various temperature used as method produce bio-oil. The decomposition profile examined at different heating rates (10, 20, 30, 40°C/min) using thermogravimetric analysis (TGA) method. kinetics were evaluated three kine...

NaOH, dolomite and NiCl2 were used as catalysts to examine their effects on co–pyrolysis with waste bicycle tires (WT) engine oil (WEO). The pyrolysis behaviors investigated by thermogravimetric analysis. activation energy of the catalytic main reaction stage was derived Kissinger–Akahira–Sunose (KAS) method under four different heating rates conditions. calculations show that all three can red...
