Photopolymerization devises light intensity relation with physical translucid barriers use
(2020)
Abstract:
Nowadays, the use of halogen or light emission diode (LED) devices in dental attention is constant for almost any oral treatment. The need of providing an adequate light intensity for a correct photopolymerization ...
Analysis of seed-germination in Piptadenia-Gonoacantha (Mart) MACBR (Leguminosae Mimosoideae)
(Inst Tecnologia Parana, 1994-01-01)
Preliminary tests indicated 20-degrees-25-degrees-C as optimum temperature range to the germination of the seeds of P. gonoacantha. Seeds germinate both under light and dark conditions, although final percentage is always ...

Light intensity preference of juvenile pikeperch Sander lucioperca (L.)
(Blackwell Publishing, 2006-11-15)
Light intensity preference of the pikeperch was tested in 1-m(2) tanks divided into four lateral compartments with a hole in the middle to allow the fish to move between compartments. Two experiments were carried out with ...
Effects on Light Efficiency in Discharge and Solid-State Lighting Operation, Supplied by No-Sinusoidal Voltage
(Ieee-inst Electrical Electronics Engineers Inc, 2016-05-01)
The widespread use of discharge lamps and solid-state lighting is justified by its high-energy efficiency. However, the massive use causes degradation of power quality provided. In this context, the objective was the ...
Differential responses of three grasses to defoliation, water and light availability
(Springer, 2017-02)
Grazing not only modifies the structure and functioning of grasslands, it also changes micro-environmental conditions that alter the availability of resources. The aim of this study was to analyze the response of grasses ...
Superação de dormência e influência dos fatores ambientais na germinação de sementes de Spermacoce latifolia
(2011-07-01)
Understanding basic information on weed biology contributes to the implementation of appropriate management and control strategies. Thus, this work was developed to evaluate the germination of Spermacoce latifolia Aubl. ...
