Minimal Crystallizations of 3-Manifolds
We have introduced the weight of a group which has a presentation with number of relations is at most the number of generators. We have shown that the number of facets of any contracted pseudotriangulation of a connected closed 3-manifold M is at least the weight of the fundamental group of M . This lower bound is sharp for the 3-manifolds RP, L(3, 1), L(5, 2), S1 × S1 × S1, S2 × S1, S×− S1 and...
متن کاملComparative performance of concentration and temperature controlled batch crystallizations
An increased interest has been directed towards the crystallization of pharmaceuticals and proteins in recent years, which have additional complications compared to the extensively studied inorganic batch and continuous crystallizations. Recent advances in process analytical technology have enabled the improved modeling and control of batch crystallization. This paper compares simulations and e...
متن کاملSchizophrenia, personal constructs, and Riedel's constructs.
W. W. Riedel's 1970 report of an investigation of personal constructs, using schizophrenics as Ss, encourages criticism of two major aspects of such endeavors. Unwarranted application of the disease model as a paradigm for studying undesirable conduct produces a series of strategy errors: weak explication of linkages between theory and measurements, noninclusion of relevant demographic data, un...
متن کاملSpecifying the Underlying Constructs of Home Culture Attachment Scale
This study was conducted to extract first, the underlying factors of Home Culture Attachment Scale (HCAS) and second, to confirm these factors via Structural Equation Modeling (SEM) analysis. To meet this end, the scale was distributed to 374 English language learners in private language institutes in Mashhad, Iran. To determine the construct validity of the scale, Exploratory Factor Analysis (...
متن کاملMathematical Modeling and Design of Novel Semi-continuous and Continuous Crystallizations
Crystallization is an important separation technology used for the purification of products during their final stages of manufacturing. Novel semi-continuous and continuous crystallization process designs are receiving increasing attention in pharmaceutical industry due to significant advantages in terms of process, operation and costs. This dissertation aims to develop mathematical models for ...
