Land surface temperature and evapotranspiration estimation in the Amazon evergreen forests using remote sensing data

2019

Amazonian tropical forests play a significant role in global water, carbon and energy cycles. Considering the relevance of this biome and the climate change projections which predict a hotter and drier climate for the region, the monitoring of the vegetation status of these forests becomes of significant importance. In this context, vegetation temperature and evapotranspiration (ET) can be considered as key variables. Vegetation temperature is directly linked with plant physiology. In addition, some studies have shown the existing relationship between this variable and the CO2 absorption capacity and biomass loss of these forests. Evapotranspiration resulting from the combined processes of …

Revisiting neutralization theory and its underlying assumptions to inspire future information security research

2022

Over two decades ago, neutralization theory was introduced to information systems research from the field of criminology and is currently emerging as an influential foundation to both explain and solve the information security policy noncompliance problem. Much of what we know about the theory focuses exclusively on the neutralization techniques identified in the original as well as subsequent criminological writings. What is often left unexamined in IS research is the underlying assumptions about the theory’s core elements; assumptions about the actor, the act, the normative system, and the nature of neutralizing itself. The objective of this commentary is to revisit the origin of neutrali…

Modelling the effect of ethanol on growth rate of food spoilage moulds

2005

The effect of ethanol (E) on the radial growth rate (mu) of food spoilage moulds (Aspergillus candidus, Aspergillus flavus, Aspergillus niger, Cladosporium cladosporioides, Eurotium herbariorum, Mucor circinelloides, Mucor racemosus, Paecilomyces variotii, Penicillium chrysogenum, Penicillium digitatum, Rhizopus oryzae and Trichoderma harzianum) was assessed in Potato Dextrose Agar (PDA) medium at a(w) 0.99, 25 degrees C. In order to model this effect, the Monod type equation described previously by Houtsma et al. (Houtsma, P.C., Kusters, B.J.M., de Wit, J.C., Rombouts, F.M., Zwietering, M.H., 1994. Modelling growth rates of Listeria monocytogenes as a function of lactate concentration. Int…

EVAPOTRANSPIRATION, CROP COEFFICIENTS AND WATER USE EFFICIENCY OF CYPERUS ALTERNIFOLIUS L. AND TYPHA LATIFOLIA L. IN A PILOT-SCALE HORIZONTAL SUBSURF…

2014

In constructed wetland systems (CWs) for wastewater treatment, the efficiency of the system is highly affected by the system’s water balance. This study shows the results of a series of water balance measurements obtained in 2013 from a pilot horizontal-subsurface flow (HSSF) system in the West of Sicily (Italy). The system included three separate units, one planted with Cyperus alternifolius L., one planted with Typha latifolia L. and an unplanted unit. The system was fed with urban wastewater from an activated-sludge wastewater treatment plant. The aim of the study was to compare evapotranspiration rates (ET), crop coefficients (Kc) and water use efficiency (WUE) of two root emergent macr…

Application of a Split-Window Algorithm to Estimate Land Surface Temperature from NOAA-AVHRR Data

2006

Estimaciones de temperatura de la superficie terrestre, en días parciales a completamente despejados, fueron realizadas a partir de los datos proporcionados por el sensor Advanced Very High Resolution Radiometer (AVHRR), a bordo de la serie de satélites de la National Oceanic and Atmospheric Administration (NOAA) por aplicación de un algoritmo basado en el método de Split-Window. El algoritmo utilizado supone correcciones por emisividad y contenido de vapor de agua atmosférico, y fue validado con mediciones de temperatura de la superficie terrestre realizadas en terreno. Para esto, un data logger LI-1000 se instaló en la Estación Agrometeorológica dependiente del Instituto de Investigacione…

Analysis of the Potential of an Increase in Yeast Output Resulting from the Application of Additional Process Wastewater in the Evaporator Station

2019

This paper reports the results of an analysis of process wastewater streams in the context of an increase in yeast production. This research is based on the analysis of data from the biggest yeast factory in Europe. The research presented in this paper involves the analysis of the influence of direction of additional wastewater into the evaporator station on yeast production. In the process wastewater, nitrogen is mainly present in organic forms. The analysis reported in this paper involves the concentration of total nitrogen in wastewater streams, as it is the main parameter applied to determine the amount of wastewater that can be applied in agricultural fields. Directing additional waste…
