English

Subject field(s)
  • Medical Instruments and Devices
  • Scientific Research Equipment
  • Bioengineering
DEF

A flat plate with multiple wells used as small test tubes.

CONT

Assays of biochemical systems are carried out on a large scale in both industry and academia, so it is desirable to have an apparatus that allows these assays to be performed in a convenient and inexpensive fashion. Because they are relatively easy to handle and low in cost, microplates are often used for such studies. Microplates typically consist of a plurality of individual wells formed of polymeric materials. Each well includes sidewalls and a bottom so that an aliquot of a sample may be placed within each well. The wells may be arranged in relatively close proximity in a matrix pattern, allowing samples to be studied individually or as a group. Common sizes for microplates include matrices having dimensions of 4x6(24 wells) or 8x12(96 wells), although larger microplates are also used that may include matrices of hundreds or even thousands of wells.

PHR

96-well, allergen-coated microtitration plate.

Subject field(s)
  • Prosthetic Dentistry
  • Cytology
  • Biotechnology
CONT

To investigate the tooth development in the none-tooth bearing area, the tooth germs were transplanted into the toothless gap, diastema of the developing mandible. Also to study the effect of growth factors on the tooth development, BMP [bone morphogenetic protein] was added during culture period. After periods of in vitro and in vivo culture, the transplanted tooth germ in the toothless gap area showed bioengineered tooth with supportive structure formation. In BMP treated group, the bioengineered tooth was observed with increased maturation of cusp and enamel matrix, which suggest possibility of controlling of bio-engineering of the tooth in morphogenesis even in toothless area.

Subject field(s)
  • Mathematical Geography
CONT

A covariance matrix is generated using the echo returns. The presence of at least one target within a single range cell is detected. A plurality of consecutive pulses are transmitted in a direction of the single range cell within a sufficiently short period so that at least one target remains within the single range cell while the plurality of consecutive pulses are transmitted. An echo signal is sampled from each of the plurality of pulses. An updated covariance matrix is estimated each time the echo signal is sampled. An eigenvalue decomposition is updated each time the covariance matrix is updated. The number of targets in the single range cell is estimated, based on the updated eigenvalue decomposition.

Subject field(s)
  • Petroleum Deposits
CONT

There are vast, deep coalbeds in Alberta, Canada which are unmineable but contain trapped methane. The Alberta Research Council(ARC) is leading a group of provincial, national and international organizations to exploit the coalbed methane by testing a novel process of injecting carbon dioxide. This process is called Enhanced Gas Recovery(EGR). It is similar to the established practice of using CO² injection to enhance production from oil reservoirs. With EGR, the injected CO² is adsorbed in the coal, to be stored in its pore matrix, releasing the trapped methane that can be collected and sold.

Subject field(s)
  • Remote Sensing
CONT

Contingency Table. A table that compares mapped data with ground data to determine accuracy. The "known" classes derived from accuracy assessment plots are compared to the classes derived from photo interpretation. The results are then tabulated in the form of a contingency table to determine the degree of misclassification that has occurred between classes. Also referred to as error matrix, confusion matrix, or misclassification matrix.

CONT

À cet effet, afin d'évaluer la précision de la classification réalisée, il est nécessaire de réaliser une matrice de confusion telle que définie par Story et Congalton (1986). Pour chaque classe d'habitats, elle indique le pourcentage de pixels de l'ensemble de référence qui se classe correctement ainsi que la répartition des pixels dont la classe résultante diffère de la classe de référence. On peut ainsi analyser les sources de confusion entre les classes et tenter d'expliquer ces phénomènes.
