Study of fat absorption in a patient requires the determination of the fat content of feces. Quantitative chemical methods available for such determinations are too laborious to be practical for routine analyses. Estimation of the fat content of feces by microscopic examination, practised by many clinicians, is unreliable; this can be demonstrated by comparing the results of microscopic determi...

The unitarity relations for isovector nucleon form factors in the two-pion approximation for the intermediate states are analytically extended in a model independent way from the real half-axis t > 4μ2 (μ is the pion mass) to the whole complex tplane. As a result, the explicit integral representations for the nucleon form factors are constructed in terms of the pion form factor and imaginary pa...

Congenital anomalies of the first branchial cleft are rare. Approximately 32 cases of cervicoauricular fistulae have been reported in the past hundred years: this includes the writer's own case in this review. The majority of sinuses and fistulae derived from the lateral cervical vestiges are concerned with the second pharyngeal pouch and its corresponding cleft. Auricular and pre-auricular fis...

In this paper we systematically derive randomized algorithms (both sequential and parallel) for sorting and selection from basic principles and fundamental techniques like random sampling. We prove several sampling lemmas which will find independent applications. The new algorithms derived here are the most efficient known. From among other results, we have an efficient algorithm for sequential...

Over the past decade there have been a progression of beautiful experiments on elastic electron proton scattering starting with the work of Hofstadter and collaborators and extending to broad new rang-es of higher energies and momentum transfers in the recently reported results from the Stanford Linear Accelerator Center. From these the proton electromagnetic form factors have been deduced up t...

El siguiente trabajo busca reconocer los aspectos que permiten definir al rito mágico como acto performático, indagando en las configuraciones semio-antropológicas resultan de la disposición movimiento corporal, danza y objetos participantes del rito.
