A mathematical model using classical cake-filtration theory and the surface-renewal concept is formulated for describing cross-flow microfiltration under dynamic and steady-state conditions. The model can predict the permeate flux and cake buildup in the filter. The three basic parameters of the model are the membrane resistance, specific cake resistance and rate of surface renewal. The model i...

We have studied the electronic and magnetic properties of Fe-Pt, CoPt and Ni-Pt alloy systems in ordered and disordered phases. The influence of various exchange-correlation functionals on values of equilibrium lattice parameters and magnetic moments in ordered Fe-Pt, Co-Pt and Ni-Pt alloys have been studied using linearized muffin-tin orbital method. The electronic structure calculations for t...

rice bran is a major by-product of the rice milling process that contains high amounts of fiber, proteins, fats, vitamins, minerals as well as antioxidants and hence can be utilized in enriching food products. the main aim followed in this study was to determine the effects of rice bran of variable particle sizes (53, 125 and 210 µm) and its quantity (0, 5, 10, 15 and 20%) on the quality of bat...

Cloutier, Nyman, and Su (Mathematical Social Sciences 59 (2005), 26–37) initiated the study of envy-free cake-cutting problems involving several cakes. The classical result in this area is that when there are q players and one cake, an envy-free cake-division requiring only q − 1 cuts exists under weak and natural assumptions. Among other results, Cloutier, Nyman, and Su showed that when there ...

Polarized x-ray absorption near edge structure ~XANES! spectra at both the Cu and Ge K edges of CuGeO3 are measured and calculated relying on the real-space multiple-scattering formalism within a one-electron approach. The polarization components are resolved not only in the unit cell coordinate system («i a , «i b , «i c) but also in a local frame attached to the nearest neighborhood of the ph...

In this study, a circulating fluidized bed (CFB) of 125 mm diameter and 1800mm height was used to find the combustion characteristics of sewage sludge (SS) produced in Turkey. Sludge + olive cake, and sludge + lignite coal mixtures were burned separately. Various sludge-to-lignite coal and sludge-to-olive cake ratios (5/95, 10/90, 15/85, 20/80) were tried. On-line concentrations of major compon...

BACKGROUND Ganglioneuroblastoma is a tumor of peripheral neuroblastic tissue which occurs predominantly in the pediatric age group; it is a rare occurrence in the newborn period with only one case reported at birth to date. CASE PRESENTATION We report the case of a newborn male baby of Brahmin ethnicity from Nepal who presented with respiratory distress and blueberry muffin skin lesions after...

Multiple-Scattering Theory Beyond The MutTm-Tin Approximation J. Molenaar Mathematics Consulting Department Katholieke Universiteit Toernooiveld 6525 ED Nijmegen We present a new derivation of multiple-scattering theory as applied in solid state physics. The present approach is a generalization of the well-known Korringa, Kohn and Rostoker (KKR) formalism and holds also in the case of overlappi...

It is expected that personal devices should be more intellecutual and reliable presence for the user in the ubiquitous computing environment. Context awareness is significant ability to realize such expectation, however, it has not been enough discussed that what type of sensors are effecient and context are acquirable in the existing research. We have developed Muffin which has 15 sensors and ...

We address the problem of fair division, or cake cutting, with the goal of finding truthful mechanisms. In the case of a general measure space (“cake”) and non-atomic, additive individual preference measures or utilities we show that there exists a truthful “mechanism” which ensures that each of the k players gets at least 1/k of the cake. This mechanism also minimizes risk for truthful players...
