Conifer needles as thermoplastic composite fillers: structure and properties
2016
This study describes the properties of thermoplastic polymer composites based on polyethylene (of low and high density) and ethylene-propylene copolymers using various types of conifer needles (pine, spruce, fir, and cedar) as fillers. For the needles, thermogravimetric analysis (TGA) and TGA/Fourier transform infrared spectroscopy (TGA/FTIR) were performed to investigate their structures and thermal resistance, as required for the composite processing methods. Moreover, structural differences were studied for the analyzed fillers and composite materials (FTIR). The results were compared with the values obtained for composites with conifer wood flour. Composites with conifer needles (pine) …
Efficacy of microbial consortia and natural compounds as seed treatment for tomato pathogen management
2022
In this study the efficacy of experimental treatments based on microbial consortia (MC) (beneficial rhizobacteria and fungi, actinomycetes, arbuscular mycorrhizal fungi) and natural compounds (NCs) (chitosan and glucosinolates) as seed treatments for tomato bacterial and fungal pathogens management (Xanthomonas euvesicatoria pv. perforans, Xep; Pseudomonas syringae pv. tomato, Psto; Fusarium oxysporum f. sp. radicis-lycopersici, FORL) was evaluated. Independent trials were performed by using organic tomato seeds ‘San Marzano nano’. Treatments were performed by soaking seeds either in aqueous MC suspensions or NC dilutions. The direct effect on the seed inoculum was performed on seeds inocul…
Hierarchical structure of the Sicilian goats revealed by Bayesian analyses of microsatellite information
2010
Genetic structure and relationship amongst the main goat populations in Sicily (Girgentana, Derivata di Siria, Maltese and Messinese) were analysed using information from 19 microsatellite markers genotyped on 173 individuals. A posterior Bayesian approach implemented in the program STRUCTURE revealed a hierarchical structure with two clusters at the first level (Girgentana vs. Messinese, Derivata di Siria and Maltese), explaining 4.8% of variation (amovaФ(ST) estimate). Seven clusters nested within these first two clusters (further differentiations of Girgentana, Derivata di Siria and Maltese), explaining 8.5% of variation (amovaФ(SC) estimate). The analyses and methods applied in this stu…

Diseño y validación de un dispositivo para la cuantificación de la lordosis lumbar basado en sensores inerciales
2017
El dolor de espalda sigue siendo un problema importante en la actualidad y, la lumbalgia es una de sus consecuencias más directas y habituales. Se puede decir que es un preocupante problema a nivel mundial y no se conocen estrategias de tratamiento que realmente sean eficaces. Es la enfermedad reumática más atendida en centros de salud y clínicas y tiene como resultado un considerable gasto financiero, de mano de obra y de costes sociales. Se ha visto que, si bien numerosas patologías se han asociado al dolor lumbar, a menudo es difícil establecer una causa clara o un factor para determinar el origen de ese dolor en la persona. La mayoría de lumbalgias atendidas se etiquetan como "no especí…
Monitoring the effects of therapeutic interventions in depression through self-assessments
2021
The treatment of major psychiatric disorders is an arduous and thorny path for the patients concerned, characterized by polypharmacy, massive adverse side effects, modest prospects of success, and constantly declining response rates. The more important is the early detection of psychiatric disorders prior to the development of clinically relevant symptoms, so that people can benefit from early interventions. A well-proven approach to monitoring mental health relies on voice analysis. This method has been successfully used with psychiatric patients to ‘objectively’ document the progress of improvement or the onset of relapse. The studies with psychiatric patients over 2-4 weeks demonstrated …
Phytotoxic effects of commercial essential oils on selected vegetable crops: Cucumber and tomato
2020
Abstract Essential oils of Origanum vulgare L., Rosmarinus officinalis L., Thymus mastichina L., Ocimum basilicum L., Melaleuca alternifolia Maiden & Betche ex Cheel, Eucalyptus globulus Labill., Gaultheria procumbens L. and Origanum majorana L., with herbicidal effects at different doses (0.125, 0.250, 0.50 and 1 μL/mL) were tested against Cucumis sativus L. and Solanum lycopersicum L., in order to ensure their harmlessness against these Mediterranean food crops. Oregano (carvacrol 60.42%) was the most damaging essential oil, exhibiting a dose-dependent phytotoxic activity against the seed germination and seedling growth of cucumber and tomato, whereas rosemary (1,8-cineole 24.95%, camphor…
Bird assemblages in isolated Ficus trees in Kenyan farmland
2006
Over the last few decades a rapid and extensive conversion of tropical forests to agricultural land has taken place resulting in mosaics of fragmented forest patches, pastures and farmland. While the effects of forest fragmentation on biodiversity have been intensively studied within the remaining forests, relatively little is known about the biodiversity in tropical farmland (Daily et al. 2001, Pimentel et al. 1992). Frugivorous birds are an important group of species in tropical farmland ecosystems. Frugivorous birds are significant seed dispersers and can play a prominent role in transporting seeds into disturbed areas and setting the stage for the regeneration of these systems. Isolated…
Feeding strategy of the sacoglossan opisthobranch Oxynoe olivacea on the tropical green alga Caulerpa taxifolia.
2007
The feeding behaviour of the shelled sacoglossan Oxynoe olivacea was investigated to better understand the role and importance of this species in influencing encroachments of the alien alga Caulerpa taxifolia in the Mediterranean sea. We tested whether this slug preferred, as preliminary field observations suggested, an aggregative feeding behaviour and which part of the algal thallus, phylloid vs rhizoid, it preferred. Results showed that O. olivacea fed in groups and actively selected phylloid. This outcome poses important questions regarding the possibility that this species, fragmenting the alga thallus, could enhance dispersion and regeneration of C. taxifolia.
