For a Peirce algebra P, lattices CongP of all heterogenous Peirce congruences and IdeP of all heterogenous Peirce ideals are presented. The notions of kernel of a Peirce congruence and the congruence induced by a Peirce ideal are introduced to describe an isomorphism between CongP and IdeP. This isomorphism leads us to conclude that the class of the Peirce algebras is ideal determined. Opposed ...
This is a report investigating the suitability of mobile agents to exploit computational resources in heterogenous networks. As a first draft it is not intended to provide a final result. A differentiated view over existing solutions to provide heterogenous computing with nodes in the network is made. Although the agent paradigm for designing complex systems and for the use in grids is acknowle...
Theoretical work predicts that the strong dependence of Tc on pure shear strain within the a-b plane of optimally doped YBa2Cu3O7−δ results in heterogenous columnar pins of vortex lines about dislocation lines and about nano-columns inclusions aligned in parallel to the c axis. The critical current of a rigid vortex lattice driven by the Lorentz force in the presence of such clusters of pin/ant...
Non-Hodgkin’s lymphoma is a heterogenous group of lymphoid malignancies with marked vanabiity in morphologic features, growth pattern, antigemc phenotype and biological behaviout Tcell rich B-cell lymphoma (TCRBCL) is a newly recognised entity of this large heterogenous group of lymphoid neopiasms which closely mimics Hodgkin’s disease and peripheral T-cell lymphoma (PTCL). Most of the cases of...
Several contributions have already pointed out that initial wealth inequalities do persist in the long run in the Ramsey model with heterogenous agents. We show that this result is not robust to the introduction of endogenous fertility. Our argument builds on the Barro-Becker (1989) seminal model extended to allow for heterogenous agents with different capital endowments. Strikingly enough, ind...
Due to the heterogenous power-saving requirement in wireless sensor networks, we propose the Cyclic Quorum System Pair (CQS-Pair) which can guarantee that two asynchronous nodes adopt different cyclic quorum systems can hear each other at least once in bounded time intervals. To quickly assemble a CQS-Pair, we present a fast construction scheme, which is based on the Multiplier Theorem and the ...
Enhancing P-xylene selectivity during m-xylene transformation using mildly pre- coked ZSM-5 catalyst
In the present work, the transformation of m-xylene was studied over fresh and pre-coked HZSM-5 catalyst in a riser simulator over the temperature range of 350-500C.Significant differences were observed in both the activity and product selectivity pattern for the two forms of the catalyst. While, the fresh catalyst generally gave higher m-xylene conversion, the pre-coked catalyst produced highe...
A triethylaluminium(TEAl)-modified Phillips ethylene polymerisation Cr/Ti/SiO2 catalyst has been developed with two distinct active regions positioned respectively in the inner core and outer shell of the catalyst particle. DRIFTS, EPR, UV-Vis-NIR DRS, STXM, SEM-EDX and GPC-IR studies revealed that the catalyst produces simultaneously two different polymers, i.e., low molecular weight linear-ch...
background: toxocariasis is a prevalent zoonosis disease caused by the closely related nematode species toxocara canis and toxocara cati which parasitise canidae and felidae respectively. in paratenic hosts, larvae of these worms cause multiple organ damage. however, how these paratenic hosts response to these worms and whether any common biomarker can be applied for diagnosis are still unclear...
