Optimal Spectral Wavelengths for Discriminating Orchard Species Using Multivariate Statistical Techniques
2019
Sustainable management of orchard fields requires detailed information about the tree types, which is a main component of precision agriculture programs. To this end, hyperspectral imagery can play a major role in orchard tree species mapping. Efficient use of hyperspectral data in combination with field measurements requires the development of optimized band selection strategies to separate tree species. In this study, field spectroscopy (350 to 2500 nm) was performed through scanning 165 spectral leaf samples of dominant orchard tree species (almond, walnut, and grape) in Chaharmahal va Bakhtiyari province, Iran. Two multivariable methods were employed to identify the optimum wavelengths:…
Perspectiva diacrónico-contrastiva del paisaje lingüístico de la migración en el barrio de Ruzafa de Valencia
2019
Este trabajo tiene como principal objetivo conocer el grado de presencia de las lenguas de inmigración en el paisaje lingüístico (PL) de Ruzafa en los años 2008 y 2018 desde un planteamiento diacrónico y contrastivo, así como explorar las consecuencias que ha tenido el proceso de gentrificación sobre el paisaje lingüístico de la migración en el barrio. Para ello se ha elaborado un corpus de un total de 212 signos del PL a partir de capturas de pantalla de las imágenes de Google Street View, las cuales pertenecen los años 2008 y 2018 y muestran los rótulos y signos de algunos comercios privados del barrio. En el análisis se han tenido en cuenta las lenguas que aparecen en los signos, el tipo…
Evolutionary Dynamics of Pathoadaptation Revealed by Three Independent Acquisitions of the VirB/D4 Type IV Secretion System in Bartonella
2017
The α-proteobacterial genus Bartonella comprises a group of ubiquitous mammalian pathogens that are studied as a model for the evolution of bacterial pathogenesis. Vast abundance of two particular phylogenetic lineages of Bartonella had been linked to enhanced host adaptability enabled by lineage-specific acquisition of a VirB/D4 type IV secretion system (T4SS) and parallel evolution of complex effector repertoires. However, the limited availability of genome sequences from one of those lineages as well as other, remote branches of Bartonella has so far hampered comprehensive understanding of how the VirB/D4 T4SS and its effectors called Beps have shaped Bartonella evolution. Here, we repor…
Plant Specialized Metabolites in Hazelnut (Corylus avellana) Kernel and Byproducts: An Update on Chemistry, Biological Activity, and Analytical Aspec…
2019
Abstract Corylus avellana (hazelnut) is one of the most popular tree nuts on a worldwide basis. The main products of C. avellana are kernels, a nutritious food, with a high content of healthy lipids, contained in a hard shell. In recent years, along with the ongoing research carried out on hazelnut kernels, a growing interest has been addressed to the hazelnut byproducts including hazelnut skin, hazelnut hard shell, and hazelnut green leafy cover as well as hazelnut tree leaf. These byproducts deriving from the roasting, cracking, shelling/hulling, and harvesting processes have been found as a source of “phytochemicals” with biological activity. The aim of this review is to provide a compre…
Community Analysis of Culturable Sapwood Endophytes from Apulian Olive Varieties with Different Susceptibility to Xylella fastidiosa
2021
Endophytes are symptomless fungal and/or bacterial microorganisms found in almost all living plant species. The symbiotic association with their host plants by colonizing the internal tissues has endowed them as a valuable tool to suppress diseases, stimulate growth, and promote stress resistance. In this context, the study of culturable endophytes residing the sapwood of Apulian olives might be a promising control strategy for xylem colonizing pathogens as Xylella fastidiosa. To date, olive sapwood cultivable endophytes are still under exploration; therefore, this work pursues a study of cultivable endophytes occurrence variation in the sapwood of different olive varieties under the effect…
Predicting species richness of wood-inhabiting fungi, epiphytic bryophytes and lichens based on stand structure and indicator species
2015
Maailmanlaajuinen monimuotoisuuden vähentyminen on ollut suuri huolenaihe jo useiden vuosikymmenten ajan. Lauhkeat lehtimetsät ovat yksi eniten ihmisen vaikutuksesta kärsineistä biomeista ja eteenkin vanhat, luonnontilaiset metsät ovat vähentyneet huolestuttavasti. Ilmaston ja maisemallisten tekijöiden lisäksi metsän historia, häiriödynamiikka, metsätalous ja ekologinen jatkuvuus vaikuttavat metsän rakenteelliseen monimuotoisuuteen ja näin ollen myös lajirunsauteen. Monet lajiryhmät ovat kuitenkin huonosti tunnettuja ja vaikeasti havaittavissa, eikä lopullisia syitä lajin häviämiseen alueelta pystytä varmasti sanomaan. Tutkimukseni tarkoitus oli selvittää, mitkä elementit metsän rakenteessa…
Architettura e Potere. Peter Eisenman, intervista di Gregorio Carboni Maestri e Simona de Simoni.
2012
La relazione tra architettura e potere risulta complessa da molti punti di vista. Ogni forma di potere, infatti, rappresenta e amministra se stessa attraverso dispositivi spaziali e architettonici. Lei come interpreta questa relazione? Si potrebbe dunque sostenere che soltanto l'opera ha potere, ma non l'architetto?

Factores psicosociales asociados al fenómeno y a la práctica de Street Workout
2019
La práctica deportiva se ha considerado una herramienta muy útil en la promoción de valores y el uso que se le da puede llegar a determinar en gran medida los resultados que se deriven de ella. Además de los beneficios físicos y psicológicos, la práctica deportiva pueden tener un papel relevante en la integración social. No obstante, no hay que olvidar que el contacto social a través del deporte también puede ser negativo, llegando a generar conflictos, comportamientos contrarios a la integración o conductas que atenten contra la integridad de las personas y de la práctica deportiva en sí misma. Por lo que queda reflejada la importancia del entorno que se promueva a través de esta. A pesar …
