A novel pilot study of automatic identification of EMF radiation effect on brain using computer vision and machine learning
2020
Abstract Electromagnetic field (EMF) radiations from mobile phones and cell tower affect brain of humans and other organisms in many ways. Exposure to EMF could lead to neurological changes causing morphological or chemical changes in the brain and other internal organs. Cellular level analysis to measure and identify the effect of mobile radiations is an expensive and long process as it requires preparing the cell suspension for the analysis. This paper presents a novel pilot study to identify changes in brain morphology under EMF exposure considering drosophila melanogaster as a specimen. The brain is automatically segmented, obtaining microscopic images from which discriminatory geometri…
1400 years of man-environment interactions and soil evolution in the Saint-Mont mountain (Remiremont, Vosges)
2021
International audience; The SolHoM(a) project aims at determining the degree of landscape anthropisation in the Fossard massif (Remiremont, Vosges, France) by estimating the impact of past human occupations on current soils. Nowadays, a forest covers this relatively inhospitable mountain (hard climate, steep slopes, acid soils ...), but some remains suggest human presence for at least 1400 years.The Saint-Mont is a variscan orogenic granitic summit (height 672m) with valuable preserved archaeological relics, located south of the Fossard. At the top was founded the monasterium Habendum (from the 7th century to the French Revolution), which potentially comes after a late-antic castrum.Further…
Physicochemical, Nutraceutical and Sensory Traits of Six Papaya (Carica papaya L.) Cultivars Grown in Greenhouse Conditions in the Mediterranean Clim…
2020
Six papaya (Carica papaya L.) cultivars, grown in a Mediterranean climate under greenhouse conditions, were screened for physicochemical properties, antioxidant capacity, nutritional and sensory characteristics. The fruits, harvested with more than 50% of yellow surface (between 60% and 77%) were tested for carotenoids content, phenolic content, reducing activity (ABTS) and cellular antioxidant activity (CAA50). The physicochemical traits were measured in terms of the titratable acidity and soluble content whereas proximal composition along with moisture, fats, total sugar, ash, vitamin A, C and E content. Moreover, the sensory profile was analyzed by a semi-trained panel. Although the six …

Fish Diets in Aquaponics
2019
AbstractFish and feed waste provide most of the nutrients required by the plants in aquaponics if the optimum ratio between daily fish feed inputs and the plant growing area is sustained. Thus, the fish feed needs to fulfil both the fish’s and plant’s nutritional requirements in an aquaponic system. A controlled fish waste production strategy where the nitrogen, phosphorus and mineral contents of fish diets are manipulated and used provides a way of influencing the rates of accumulation of nutrients, thereby reducing the need for the additional supplementation of nutrients. To optimize the performance and cost-effectiveness of aquaponic production, fish diets and feeding schedules should be…
Are woodland key habitats biodiversity hotspots in boreal forests?
2011
Background: The concept of Woodland Key Habitats (WKH, small-scaled presumed hotspots of biodiversity) has become an essential component of forest management in Fennoscandian and Baltic countries. There have been debates over the importance of WKHs in relation to production forests, and several research projects have focused on differences in biodiversity between the two. Results have been contradictory, and thus there is a need to summarize and clarify the existing knowledge. - Objectives: Our objective was to summarize knowledge on comparisons of several biodiversity qualities between WKHs and production forests in relevant countries i.e. the countries where WKH concept has been implement…
Edaphyc characteristics and floristic composition of the seasonally dry forest la menta and timbes, Piura Region, Peru
2011
Con el objetivo de contribuir al conocimiento de los ecosistemas naturales del país, se determinó las características edáficas y la composición florística del bosque estacionalmente seco (La Menta, 04º 43' 55" LS y 80º 04' 55" LO, provincia de Piura y Timbes, 04º 44' 58" LS y 80º 03' 33" LO, provincia de Ayabaca), ambos en la región Piura, Perú. El área de estudio abarcó una extensión aproximada de 6 000 hectáreas en un rango altitudinal entre 350 m a 1 350 m. En cada bosque se muestrearon 5 transectos de 10 x 50 m a intervalos de 20 m, sumando un total de 2 500 m². El análisis de suelo reveló niveles bajos de materia orgánica, nitrógeno y potasio y medios de fósforo asimilable. Estos suelo…
Climate variability in forest management planning: The LIFE AForClimate project.
2018
Previous research experiences have shown that climate variability can play a relevant role in forest planning and management within a climate change scenario. In forest planning and management, yield tables, site quality indices, age classes, and rates of growth are some of the most frequently used parameters and tools. However, these ‘traditional’ methods do not include the influence of climate variability on forest growth over time, although it is one of the main influencing factors in tree growth. Changes in climate determine changes in thermo-pluviometric regimes that often have a marked influence on forest growth trends. Forest biomass, resilience, and carbon sequestration may be damag…
Willingness to Adopt Biochar in Agriculture: The Producer’s Perspective
2017
Most research on biochar has focused either on the mechanistic or the biophysical aspects, and there has been relatively little research into the social applicability and acceptance of biochar as a soil enhancer in agriculture. However, whether to adopt biochar in their practice is ultimately the farmers’ decision, and their willingness to do so is crucial. Here, we show the producer’s perspective on adopting biochar, using Polish farmers as a case study. Poland is an interesting case study because biochar has only recently attracted the attention of researchers, entrepreneurs, and other stakeholders there. We performed standardized, semi-structured interviews with 161 Polish farmers to eva…
Tree invasions in Italian forests
2022
Many forest tree species have been moved outside their native range to provide goods and services elsewhere, but some of them have become invasive, causing negative impacts on biodiversity and human activities. The assessment and knowledge on the degree and scale to which forest ecosystems are invaded by non-native trees is of paramount importance for tailored policies and strategies aiming at forest conservation. By analyzing main databases and literature and applying a four-level scale of invasion (not currently invaded and with low invasibility; potentially invasible; moderately invaded; massively invaded), we assessed the current and potential occurrence of twenty-five invasive non-nati…
