The retardancy effect of char formation upon the flammability of thermally thin products is investigated. The char is formed in a single-step non-competitive scheme and is assumed to be thermally stable. The criterion for ignition is that of a critical mass flux of volatiles from the solid into the gas phase. Both steady-state and transient formulations of the model are considered. In the high ...

We show that the locus of the foci of a family of ellipses that are tangential to the sides of a triangle with one prescribed point of tangency is an elliptic curve. We further show that every isomorphism class of elliptic curves over an algebraically closed field K of char(K) 6= 2, 3 can be realized in this manner. On varying the triangle, one can get all elliptic curves over an algebraically ...

The current research focuses on assessing the potential of municipal solid waste (MSW) conversion into biofuel using pyrolysis process. MSW samples were taken from Zaatari Syrian Refugee Camp. physical and chemical characteristics studied proximate elemental analysis. results showed that moisture content is 32.3%, volatile matter (VM) 67.99%, fixed carbon (FC) 5.46%, ash 24.33%. analysis was co...

We aim to design a system for classifying scientific articles based on the presence of protein characterization experiments, intending to aid the curators populating JCVI’s Characterized Protein (CHAR) Database of experimentally characterized proteins. We trained two classifiers using small datasets labeled by CHAR curators, and another classifier based on a much larger dataset using annotation...

The yields of char, tar, and non-condensible gases from the pyrolysis of Pinus radiata D. Don bark were measured. Pyrolysis of bark, on a small preparative scale using an airacetylene flame, gave 48% char with ash content 3.5% (mainly aluminium, calcium, potassium, and silica), and recovered tar in 7% yield (on oven-dried bark equivalent). The major components of the pyrolysis tar were catechol...

KITP is an automated inference system developed for supporting the formal design, veriication, and validation of computer programs. It has evolved from an automated veriication system, RVF 5]. The latest version of KITP, KITP-93, features a typed formulation and deduction, meta-level reasoning, and resolution-based proving enhanced by conditional term-rewriting. This report describes KITP-93 fr...

Anthropogenic activities are greatly altering the habitats of animals, whereby fish are already encountering several stressors simultaneously. The purpose of the current study was to investigate the capacity of fish to respond to two different environmental stressors (high temperature and overnight hypoxia) separately and together. We found that acclimation to increased temperature (from 7.7±0....

Let G be a nite group, let V be an F G-module of nite dimension d, and denote by (V; G) the minimal number m such that the invariant ring S(V) G is generated by nitely many elements of degree at most m. A classical result of E. Noether says that (V; G) jGj provided that char F is coprime to jGj!. If char F divides jGj then no bounds for (V; G) are known except for very special choices of G. In ...
