Image analysis methods to monitor natura 2000 habitats at regional scales - the ms. monina state service example in schleswig-holstein, Germany

Summary: The Natura 2000 network of protected sites is one of the means to address the issue of biodiversity conservation in Europe. Protected under the habitat directive, EU member states have to undertake surveillance of habitats and species of community interest and report every six years on habitat range and distribution, conservation status and the future prospects of the habitats within and

Mapping tropical dry forest succession with chris - Proba hyperspectral images using non-parametric decissional trees

Information on the distribution, level of fragmentation, extent and ecosystem health of tropical forests is key for sustainable landscape management. Therefore, information generated from different types of multispectral and hyperspectral sensors is key to monitoring programs that aimed to link ecosystems dynamics to ecosystem services such as carbon sequestration. This is especially significant f

Deep into the mud : ecological and socio-economic impacts of the dam breach in Mariana, Brazil

We review the ecological and socio-economic impacts of the catastrophic dam failure in Mariana, Brazil. Tailing management practices by Samarco mining company ultimately caused a dam breach that abruptly discharged between 55 and 62 million m3 of tailings into the Doce River watershed. On November 5th, 2015, a tsunami of slurry engulfed the small district of Bento Rodrigues, loading the Doce River

Lactic Dehydrogenase in Umbilical Cord Blood in Healthy Infants after Different Modes of Delivery

Background: LDH may be a valuable marker for some of the most important diseases in newborns, and umbilical cord blood is a non-invasive and easy way to obtain blood for analysis. Aims of this study were to define interval for LDH in arterial and venous cord blood at delivery in truly healthy newborns. Method: a prospective observational study was performed at Soder Hospital, Stockholm, Sweden dur

Correction for Residual Effects of B1+ Inhomogeniety on MT Saturation in FLASH-Based Multi-Parameter Mapping of the Brain

Maps of the MT-saturation as derived in FLASH-based multi-parameter mapping (MPM) are largely corrected for effects of flip angle inhomogeneity. Here, we present a heuristic model for residual effects of B1+ that is rooted in the dynamics of macromolecule saturation. Model parameters were validated for brain tissues by variation of the MT-pulse flip angle in an established MPM protocol. White and

Description and calibration of the ISO tapping machine in numerical impact sound predictive tools

One of the challenges in wooden constructions is to be able to achieve a good acoustic insulation especially in the low frequency range. The prediction of acoustic performance of wooden buildings before erection becomes important and reliable predictive tools are in great need. To that end, the first question that arises is how to accurately model the excitation source which generates the structur

OSL PROPERTIES IN VARIOUS FORMS OF KCl AND NaCl SAMPLES AFTER EXPOSURE TO IONIZING RADIATION

The aim of this work was to investigate the optically-stimulated luminescence (OSL) properties of potassium chloride (KCl) and its potential use in radiation dosimetry. The optimal condition for OSL readout with blue light stimulation were designated using a commercially available Risø TL/OSL reader. KCl was studied in three sample forms: crystals, powder and pellets. The following OSL characteris

Introducing the concept of the isodose for optimisation of decontamination activities in a radioactive fallout scenario

In the recovery phase after a radioactive release incident, it is important to be able to focus decontamination operations on the areas that contribute most to the radiation dose. Monte Carlo simulations were applied to determine the shielding effect of a building against radiation from various directions, also giving information on the dose contributions at various locations inside the building f

Modeling walking on a lightweight wooden floor

The most common sound insulation problem for lightweight timber structures is impact sounds from people walking. This is especially apparent in the low frequency range, due to differences in weight, stiffness, density and repartitioning as compared to more traditional materials. As lightweight timber structures increase their market share, the understanding of their behaviour and the ability to pr

Excretion Rate and Distribution Volumes in Common Marmoset Monkeys After Slow and Fast Injection of Gadobutrol

Common marmoset monkeys (Callithrix jacchus) are increasingly used in models of neurodegenerative diseases. Serial measurements of gadolinium excretion were performed using the dual flip angle method to map R1 on three animals in the wrist coil of a 3T whole-body system. R1 values were analyzed in a ROI in the straight sinus and fitted with a single compartment model. Slow injection of 0.3 mmol Ga

Twenty-first century remote sensing technologies are revolutionizing the study of tropical forests

The fields of tropical biology and conservation face significant transformations due to rapid technological developments in remote sensing. Other fields (e.g. Archeology) are experiencing this momentous change even more rapidly. In this article, we review some of the challenges that the fields of tropical biology and conservation face during the first quarter of the twenty-first century from the p

Quantifying changes on forest succession in a dry tropical forest using angular-hyperspectral remote sensing

The tropical dry forest (TDF) is one the most threatened ecosystems in South America, existing on a landscape with different levels of ecological succession. Among satellites dedicated to Earth observation and monitoring ecosystem succession, CHRIS/PROBA is the only satellite that presents quasi-simultaneous multi-angular pointing and hyperspectral imaging. These two characteristics permit the stu

Monitoring Flooding Damages in Vegetation Caused by Mining Activities Using Optical Remote Sensing

Ground removal during the mineral extraction in mine galleries provokes permanent changes in ground compacting during mine exploitation and after mine closure. In extreme cases, the loss of cohesion in ground layer over mines causes surface subsidence and eventually the emergence of flooded areas on the surface. Mining companies are obligated to the surveillance and mending of damages caused by th

Target detection of mine-related flooded areas using AISA-eagle data

The present research is developed in the frame of the R&D project GMES4Mining, which aims to support particular tasks within the different phases of a mining life cycle [1]. During the exploitation and after the closure of the mine, environmental and civil impacts may happen, due to changes in the compacting properties of the soil related to mining activities. In this paper, we focus in the em
