Low cost and high efficiency cellulolytic cocktails can consolidate lignocellulosic ethanol technologies. Sugarcane bagasse (SCB) is a low cost agro-industrial residue, and its use as a carbon source can reduce the costs of fungi cultivation for enzyme production. Chrysoporthe cubensis grown under solid state fermentation (SSF) with wheat bran has potential to produce efficient enzymatic extracts for SCB saccharification. This fungus was grown under submersed fermentation (SmF) and SSF with in natura SCB, pretreated with acid or alkali and with others carbon sources...

Biological process treatment of landfill leachate produces a significant amount of sludge, characterized by high levels of organic matter from which humic acids are known to activate several enzymes of energy metabolism, stimulating plant growth. This study aimed to characterize humic acids extracted from landfill sludge and assess the effects on plants exposed to different concentrations (0.5, 1, 2 and 4 mM C L(-1)) by chemical and biological analysis, to elucidate the influence of such organic material and minimize potential risks of using sludge in natura...

In the last years, studies on captive greater flamingos have increased. Research on zoo animals is important to improve the knowledge on these species and to improve their ex-situ and in-situ conservation. The aim of the present study was to investigate the parental behaviour of a captive colony of greater flamingo hosted at Parco Natura Viva, an Italian zoological garden, to improve the knowledge on this species in zoos. In particular, the present study investigated and compared the parental care of females and males in 35 breeding pairs of greater flamingos...

Chronic non-communicable diseases such as obesity are preceded by increased macrophage infiltration in adipose tissue and greater secretion of pro-inflammatory cytokines. We evaluated the anti-inflammatory potential of Biotransformed extract, and two control extracts: In Natura and Autoclaved. The assays were performed using a cellular model with RAW264.7, 3T3-L1 cells, and RAW264.7 and 3T3-L1 co-culture. The innovation of the study was the use of Biotransformed extract, a unique phenolic extract of a bioprocessed citrus residue...

This paper aims to determine the main factors that shape the spatial patterns of alien plant species occurrence across Natura 2000 Special Areas of Conservation (SACs) in Greece, and quantify their influence. A series of spatial analysis techniques for the development of a spatial database of the factors involved, followed by a boosted negative binomial Generalised Additive Model for location scale and shape, were implemented. Native plant species richness, topography and hydrography, human population density, and a spatial preference to the northern-western sites are the key factors that explain the variation in the occurrence of alien plant species...

Understanding the processes behind change in reproductive state along life-history trajectories is a salient research program in evolutionary ecology. Two processes, state dependence and heterogeneity, can drive the dynamics of change among states. Both processes can operate simultaneously, begging the difficult question of how to tease them apart in practice. The Neutral Theory for Life Histories (NTLH) holds that the bulk of variations in life-history trajectories is due to state dependence and is hence neutral: Once previous (breeding) state is taken into account, variations are mostly random...

Lead (Pb) and cadmium (Cd) were determined in mangrove root crab (Goniopsis cruentata) tissues (in natura) and in two culinary preparations by graphite furnace atomic absorption spectrometry. Mangrove root crab samples from three sampling sites along the Jaguaripe River, Bahia, Brazil, where lead-glazed ceramics are produced, and from two commercial preparations were collected or purchased in March and April 2016. Cd levels in raw and processed samples were below the methods' limits of detection (0.016 mg kg(-1)), while Pb levels in the raw tissues were determined only in the gills (0...

Nontoxic conserving agents are in demand by the food industry due to consumers concern about synthetic conservatives, especially in minimally processed food. The antimicrobial activity of curcumin, a natural phenolic compound, has been extensively investigated but hydrophobicity is an issue when applying curcumin to foodstuff. The objective of this work was to evaluate curcumin microcrystals as an antimicrobial agent in minimally processed carrots. The antimicrobial activity of curcumin microcrystals was evaluated in vitro against Gram-positive (Bacillus cereus and Staphylococcus aureus) and Gram-negative (Escherichia coli and Pseudomonas aeruginosa) microorganisms, showing a statistically significant (p < 0...

Cultural landscapes are poorly inventoried and evaluated in protected natural areas. This study presents a novel procedure to assess cultural landscape features and their cultural values in the major protected areas of Greece. After identifying a set of culturally modified land cover types and habitat types the GIS-based survey of the entire Natura 2000 protected area network in Greece (419 sites) shows that roughly 67% of protected area land cover consists of cultural landscape features. This was corroborated by the distribution of culturally modified habitat types which take up approximately 50% of the areal cover in a subset of the nation's Natura 2000 network (241 Special Areas for Conservation)...

A major challenge for biogeographers and conservation planners is to identify where to best locate or distribute high-priority areas for conservation and to explore whether these areas are well represented by conservation actions such as protected areas (PAs). We aimed to identify high-priority areas for conservation, expressed as hotpots of rarity-weighted richness (HRR)-sites that efficiently represent species-for birds across EU countries, and to explore whether HRR are well represented by the Natura 2000 network...

Over time, the interest on soil studies has increased due to its role in carbon sequestration in terrestrial ecosystems, which could contribute to decreasing atmospheric CO2 rates. In many studies, independent variables were related to soil organic carbon (SOC) alone, however, the contribution degree of each variable with the experimentally determined SOC content were not considered. In this study, samples from 612 soil profiles were obtained in a natural protected (Red Natura 2000) of Sierra Morena (Mediterranean area, South Spain), considering only the topsoil 0-25cm, for better comparison between results...

The strawberry (Fragaria x ananassa Dutch.), is the only vegetable belonging to the rosacea family. All strawberry species have now emerged from wild species and belong to the genus Fragaria, being that this genus presents more than 45 described species, and only 11 are considered natural species. Due to the octoploid nature of strawberry and its variability after hybridization, selecting one or more characters may result in unfavorable genotypes and even the exclusion of promising ones, because negative genetic correlations have been observed among them that cause inefficient selection...

We present a supervised machine learning approach for markerless estimation of human full-body kinematics for a cyclist from an unconstrained colour image. This approach is motivated by the limitations of existing marker-based approaches restricted by infrastructure, environmental conditions, and obtrusive markers. By using a discriminatively learned mixture-of-parts model, we construct a probabilistic tree representation to model the configuration and appearance of human body joints. During the learning stage, a Structured Support Vector Machine (SSVM) learns body parts appearance and spatial relations...

Focusing on a Mediterranean Natura 2000 site in Italy, the effectiveness of the cross correlation analysis (CCA) technique for quantifying change in the area of semi-natural grasslands at different spatial resolutions (grain) was evaluated. In a fine scale analysis (2 m), inputs to the CCA were a) a semi-natural grasslands layer extracted from an existing validated land cover/land use (LC/LU) map (1:5000, time T1) and b) a more recent single date very high resolution (VHR) WorldView-2 image (time T2), with T2 > T1...

August J Cwik
Listening analytically is not listening just to what is said but listening to what is just below the surface waiting to be said. This paper looks at Jung's insight into a 'third thing' being created intra-psychically and within the analytic encounter. Ogden's concept of an 'analytic third' is used to describe the clinical aspects of this thirdness. This paper explores: how the state of thirdness is created and accessed through use of reverie and associative dreaming; how the material emerging from it is used in a from or about manner; and the eventual fate of the third in a successful analysis by a reexamination of plates four and ten of the Rosarium...

The photocatalytic degradation of textile effluent was investigated using TiO2, ZnO, and Nb2O5 catalysts under solar irradiation. The procedures were carried out at ambient conditions in April 2014, with pH 3.0 and catalyst concentration of 0.250 g L(-1). The photocatalytic activity of the oxides was evaluated by means of kinetic efficiency (rate constant and half-life time), chemical oxygen demand reduction, and absorbance reduction at 228, 254, 284, 310, 350, 500, and 660 nm (λmáx). Mineralization in terms of the formation of inorganic ions and toxicity reduction using bioassays with Artemia salina were performed...
