Solar-induced chlorophyll fluorescence (SIF), which can be used as a novel proxy for estimating gross primary production (GPP), can be effectively retrieved using ground-based, airborne and satellite measurements. Absorbed photosynthetically active radiation (APAR) is the key bridge linking SIF and GPP. Remotely sensed SIF at the canopy level (SIFcanopy) is only a part of the total SIF emission...

The process of the radiolytic degradation is a new method of mineralization by advanced oxidation of the water that can be applied for the removal of humic compounds in all water systems. However, the deep mineralization of dissolved humic acid requires very high absorbed doses (tens of kilograys) because of the aromatic nature of the main units of humic acid and the well-known chemical and bio...

UNLABELLED As one of the major organs of the excretory pathway, the kidneys represent a frequent source of radiopharmaceutical uptake in both diagnostic and therapeutic nuclear medicine. The unique organization of the functional tissues of the organ ensures transient changes in suborgan localization of renal activity. Current single-region dosimetric models of the kidneys, however, force the as...

This paper investigates axial compression process of multi-layered tubes with circular cross-section under the axial loading in the quasi-static condition using experimental method. Some specimens are prepared in seven different groups, namely; empty carbon/epoxy composite tubes, solid carbon/epoxy composite rods, empty copper tubes, composite tubes with silicon sealant filler, concentrically s...

The phosphorylation of specific non-histone proteins in isolated rat liver nuclei is modified by the addition of exogenous histone fractions. The added histones are quantitatively adsorbed and their presence in the chromatin has been verified by electron microscope autoradiography. Histone fractions Fl and FZAl stimulate phosphorylation of different nuclear phosphoproteins. Fl stimulates the ph...

A hydrothermal method for preparation of nano-size zirconia has been studied to optimize the effective parameters (precursor concentration, temperature and time) using response surface methodology (RSM). The synthesized zirconia samples were characterized through X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscopy (TEM) analyses to identify mean nano...

To achieve a good clinical outcome in radiotherapy treatment, a certain accuracy in the dose delivered to the patient is required. Therefore, it is necessary to keep the uncertainty in each of the steps of the process inside some acceptable values, which implies a global uncertainty as low as possible. This work is focused on the uncertainty evaluation of absorbed dose to water in the routine c...
