Samples of silage extract for pH value and N[H.sub.3]-N concentration were prepared by blending 50 g of fresh silage and 450 mL of doubled distilled water (w/v) to a homogenized state using a blender for 2 min, then pH was determined immediately by a digital portable pH meter (WinLab
Para la obtencion de las ecuaciones canonicas de las Secciones Conicas a partir de puntos de la curva, focos y directriz, se uso el programa Winlab
. Inicialmente, con una integracion de la visualizacion, el conocimiento de las propiedades geometricas y la ecuacion canonica general, se obtuvieron manualmente los parametros especificos del ejemplo y luego se establecio la grafica como comprobacion, asi como la obtencion de la ecuacion con el software (Figura 4-A).
UV-Vis spectrophotometry was carried out using Lambda25 UV/Vis spectrophotometer system operated with UV WinLab
V2.85 software (Perkin Elmer, USA).
Dipankar Raychaudhuri, head of the Rutgers Winlab

We measured the fluorescence spectra of QDs in n-hexane and the FMBNs in ultrapure water by means of a PerkinElmer LS 55 fluorescence spectrometer with a 388-nm laser for excitation and analyzed the results with FL WinLab
4.00.02 software (PerkinElmer).
