Tubo de Lester-Jones: indicações e resultados

OBJETIVO: Avaliar as indicações, resultados e complicações advindas do seu uso. MÉTODOS: Avaliaram-se retrospectivamente 25 pacientes submetidos a 27 conjuntivorrinostomias com colocação de tubo de Lester-Jones. Foram estudados os dados do portador, a etiologia da afecção e as complicações que ocorreram no intra e no pós-operatório. Os dados foram avaliados segundo a freqüência de ocorrência. RESULTADOS: O tubo de Lester-Jones foi usado igualmente em ambos os sexos, mais em indivíduos abaixo dos 10 ou acima dos 50 anos de idade. As causas mais freqüentes para utilização foram a idiopática ou a agenesia congênita de pontos e canalículos. Houve melhora dos sintomas em 88% dos pacientes. Complicações ocorreram em 59,25% dos casos, dentre as quais: extrusão (40,74%) e a migração (14,8%) do tubo. CONCLUSÃO: Apesar das complicações observadas, o índice de cura com a utilização do tubo de Lester-Jones é alto, sendo boa opção para o tratamento das obstruções lacrimais altas.

Confined Lennard-Jones potential: a variational treatment

In this work, the energy eigenvalues for the confined Lennard-Jones potential are calculated through the Variational Method allied to the Super symmetric Quantum Mechanics. Numerical results are obtained for different energy levels, parameters of the potential and values of confinement radius. In the limit, where this radius assumes great values, the results for the non-confined case are recovered..

Supersymmetry, variational method and the Lennard-Jones (12,6) potential

The formalism of supersymmetric quantum mechanics is used to determine trial functions in order to obtain eigenvalues for the Lennard-Jones (12, 6) potential from variational method. The superpotential obtained provides an effective potential which can be directly comparable to the original one.

Supersimetria, método variacional e potencial de Lennard-Jones (12,6)

In this work a review of the supersymmetric quantum mechanics formalism combined with the variational method is done. This approach is useful in order to obtain numerical values for the energy eigenvalues from Schrödinger equation. As an example, the energy eigenvalues from the Lennard-Jones (12,6) potential are determined and the results are compared with other ones obtained from different methods.

Dorothy Gardner Jones Papers - Accession 192

The Dorothy Gardner Jones Papers consist of correspondence, reports, program notes, clippings, memoranda, and other records, mainly relating to Jones’ work as a Winthrop faculty member and involvement with professional organizations and social service groups in the Rock Hill, South Carolina area.

John Jones Letter - Accession 7 - M6 (16)

The John Jones Letter was written by Mr. Jones in 1841, a farmer, from Montevallo, Alabama, to Jesse Trusdel of Santon in Kershaw District, South Carolina, in which Jones discusses economic and health conditions in Shelby County, Alabama, his family affairs, and future plans. The collection includes the envelope (in pieces) and a handwritten transcription.

Omtvedt Innovation Awards Presented to Chris Calkins, Steven Jones, Rodger Johnson, and Sheila Scheideler

It's a great pleasure to welcome you to this very first recognition ceremony for the Omtvedt Innovation Awards. We are present here to honor innovation strengths of the Institute of Agriculture and Natural Resources, and certainly the four faculty members receiving today's awards are greatly deserving of this recognition. Just hearing about their work is gratifying!

A comparison of face and facial feature detectors based on the viola-jones general object detection framework

[EN]The human face provides useful information during interaction; therefore, any system integrating Vision- BasedHuman Computer Interaction requires fast and reliable face and facial feature detection. Different approaches have focused on this ability but only open source implementations have been extensively used by researchers. A good example is the Viola–Jones object detection framework that particularly in the context of facial processing has been frequently used.

Viola-Jones based detectors: How much affects the training set?

[EN]This paper presents a study on the facial feature detection performance achieved using the Viola-Jones framework. A set of classi- ers using two di erent focuses to gather the training samples is created and tested on four di erent datasets covering a wide range of possibili- ties. The results achieved should serve researchers to choose the classi er that better ts their demands.
