  The fraction of absorbed photosynthetically active radiation (fAPAR) is a key parameter for estimating the gross primary production (GPP) of trees. For continuous, dense forest canopies, fAPAR, is often equated with the intercepted fraction, fIPAR. This assumption is not valid for individual trees in urban environments or parkland settings where the canopy is sparse and there are well-defined tree crown boundaries. Here, the distinction...

• Evaluating the influence of radiative heat flux on convective heat transfer from a vertical plate in air using an improved heating plate

  Publication

  • W. Lewandowski

  - INTERNATIONAL JOURNAL OF HEAT AND MASS TRANSFER - Year 2021

  This article examines the influence of radiative heat flux on the accuracy of the results of free convective heat transfer in air. In order to carry out these tests, based on the experience gained during the operation of a plate heated on one side, compensated by a reverse heat loss flux counter-heater, a unique double-sided heating sandwich plate was designed and built, consisting of three thin epoxy resin plates reinforced with...

  - JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY B-BIOLOGY - Year 2007

  Przedyskutowano niezbędne modyfikacje stałej szybkości transferu foersterowskiego w sytuacji, kiedy zanik fluorescencji donora w nieobecności akceptora jest nieeksponencjalny. Stwierdzono, że najbardziej przydatna modyfikacja wynika założenia jednakowej wartości stałej zaniku radiacyjego dla wszystkich molekuł donora.

  The main objective of this study is to determine the energy transfer occuring in ion-molecule collisions. In order to solve this problem, we followed two approaches; the first one by validating a purely experimental method and the second one by testing a new theoretical model M3C (Microcanonical Metropolis Monte Carlo).

  In the biomedical field, the use of fluorescence imaging in the second near-infrared (NIR-II) region is growing rapidly because it imparts the advantages of reduced autofluorescence and low photon scattering. The advantage of reduced scattering is that it increases penetration depth in vivo and improves imaging clarity. Herein, this work uses mesoporous...

  Förster resonance energy transfer between 7-amino-4-methyl-3-coumarinylacetic acid, (AMCA, donor) and 5- carboxytetramethylrhodamine, (TAMRA, acceptor) bound to Lys(AMCA)-Gly-Pro-Arg-Ser-Leu-Ser-Gly-Lys (TAMRA)-NH2 peptide is demonstrated by various spectroscopic techniques in glycerol at room temperature. In particular, nonexponential character of fluorescence intensity decay evidences the distance distribution between the donor...

• Control system for contactless electrical energy transfer with varying air gap

  Publication

  • S. Judek

  - Year 2014

  Inductive power transfer (IPT) is a system by which electrical energy may be transmitted without electrical connection through a large air gap between coils. Systems usually considered in the literature are the ones with a constant air gap. The paper describes the analysis of IPT, which allows for supplying an electrical load in the conditions of slow, in relation to the dynamics of power supply, changes in the dimensions of the...
