Temperature control via robust compensation of heat generation: Isoparaffin/olefin alkylation

Abstract

Introduction. There are limited evidences reported of temporal lobe epilepsy associated with active cysticercosis in cystic stage. The objective is to present the correlation between active cysticercosis in topographical zones associated with temporal lobe epilepsy, with neuropsychiatric manifestations and pattern of secondarily generalized partial seizures. Case reports. Two cases of adult patients with neuropsychiatric manifestations of one year evolution, refractory to antipsychotic drug treatment, and who subsequently appear late onset partial-secondarily generalized seizures. Cysticercosis active presence in the temporal lobe in one patient, and the insula in the other, is identified. A better clinical control after albendazol treatment and subsequently anticonvulsant therapy only remained to evaluate pertinence of pharmacological withdrawal criteria. Conclusions. Active neurocysticercosis, may be the cause of acquired neuropsychiatric disorders and temporal lobe epilepsy of late onset when the topography is in the mesolimbic circuit. Early etiologic diagnosis and appropriate treatment allows adequate control of their symptoms and potentially final cure.

Urrutia-Fucugauchi, J.",,"1998",,"The Chapala graben forms part of a regional system of intra-arc and half-grabens located along the western and central portions of the Mexican Volcanic Belt. Results of a stratigraphic and tectonic study of the thick, widespread volcano-sedimentary sequence around the Chapala graben are reported. The study has concentrated on the distribution of lacustrine deposits and on the stratigraphy, geochronology, and deformation of the sequence. The volcano-sedimentary record suggests a probable link between the Tepic-Zacoalco and Chapala grabens through a basin system developed during late Miocene and early Pliocene time. The stratigraphie sections show a southward spatial migration of the basin (and lake) system. The main unit of the volcano-sedimentary succession is the Chapala Formation, which has been affected by northeast tilting, unlike the lacustrine deposits to the east in the Chapala plain (e.g., Ixtlan area), where the sequence is essentially flat lying. Two distinct units with different structural attitudes, separated by an angular unconformity, can be distinguished in the Chapala Formation. Based on differences between the stratigraphic sections and structural attitudes, we propose a model for development of the Chapala graben that involves a combination of left-lateral and extensional deformation, together with volcanic and erosional processes, all of which have contributed to shape the basin. Furthermore, we suggest that Lake Chapala is the remnant of a large Jalisco paleo-lake in west-central Mexico.",,,,,,,,,"http://hdl.handle.net/20.500.12104/44972","http://www.scopus.com/inward/record.url?eid=2-s2.0-0031853876&partnerID=40&md5=0785553f21414994671aaa002afb760f",,,,,,"4",,"International Geology Review",,"350

Gonzalez-Alvarez, V.",,"2006",,"The temperature control of the heterogeneous alkylation, where H2SO4 is used as catalyst, is discussed in this paper. The problem is to design a control function to stabilize temperature in face of uncertain kinetic model. The proposed controller, whose structure resembles a PI-controller, is based on energy balance. The resulting feedback controller is robust, leads to an acceptable performance, and computes the temperature of the coolant from the refrigeration section to the reactor. The effectiveness and robustness of the designed controller for computing the coolant temperature is tested by means of simulations in such a manner that we study the effects of: (i) load disturbances, (ii) model uncertainties and (iii) initial conditions for estimation values.
