Application of A Precision Apiculture System to Monitor Honey Daily Production †
2020
Precision beekeeping or precision apiculture is an apiary management strategy based on the monitoring of individual bee colonies to minimize resource consumption and maximize the productivity of bees. Bees play a fundamental role in ensuring pollination

¿Marxismo o diferenciación social?
2018
Para la sociología, el debate con el marxismo forma uno de los telones de fondo intelectuales y prácticos en el surgimiento de esta joven ciencia durante el siglo xix. Uno de los puntos más interesantes de esta disputa trata del grado necesario de diferenciación de las categorías analíticas para comprender los mecanismos básicos de la sociedad. La capacidad y la necesidad de reducir la compl ejidad que requiere cada ciencia, si quiere ll egar a un nivel de generalización que permita la acción social, se contrapone a una diferenciación analítica que tenga en cuenta la máxima cantidad posibl e de elementos relevantes para la comprensión de lo social. El presente artículo alumbra las relacione…
Dissemination and national and international impact factors of spanish journals
2008
El artículo ofrece un estudio sobre las revistas científicas españolas vigentes. Se analizan datos sobre la antigüedad de las publicaciones, soporte documental, periodicidad, idiomas, difusión y visibilidad nacional e internacional. El propósito del trabajo ha sido realizar un análisis bibliométrico de las revistas científicas españolas que se editan actualmente. Se ha procedido a la consulta de diferentes directorios, repertorios y bases de datos bibliográficas. Se ha comprobado la veracidad de los datos recogidos consultando las páginas web de las revistas y a través del contacto con los editores de las publicaciones. Los resultados muestran que el comportamiento es desigual entre las rev…
Test-retest reliability of a new self reported comprehensive questionnaire measuring frequencies of different modes of adolescents commuting to schoo…
2009
Published version of an article from the journal: International Journal of Behavioral Nutrition and Physical Activity Article available from: http://www.ijbnpa.org/content/6/1/68 Background: Studies assessing active commuting to school usually use simple questionnaires, and often is mode of commuting reported with a single questionnaire item only. The purpose of the present study is to report the test-retest reliability of a newly developed comprehensive questionnaire on active commuting to school and work among 6thgrade school children and their parents in Norway. Methods: A total of 106 pupils and 77 parents completed a questionnaire two times, 14 days apart. The questionnaire consisted o…
FASTA/Q data compressors for MapReduce-Hadoop genomics: space and time savings made easy
2021
Abstract Background Storage of genomic data is a major cost for the Life Sciences, effectively addressed via specialized data compression methods. For the same reasons of abundance in data production, the use of Big Data technologies is seen as the future for genomic data storage and processing, with MapReduce-Hadoop as leaders. Somewhat surprisingly, none of the specialized FASTA/Q compressors is available within Hadoop. Indeed, their deployment there is not exactly immediate. Such a State of the Art is problematic. Results We provide major advances in two different directions. Methodologically, we propose two general methods, with the corresponding software, that make very easy to deploy …
Radiomics and Prostate MRI: Current Role and Future Applications
2021
Multiparametric prostate magnetic resonance imaging (mpMRI) is widely used as a triage test for men at a risk of prostate cancer. However, the traditional role of mpMRI was confined to prostate cancer staging. Radiomics is the quantitative extraction and analysis of minable data from medical images; it is emerging as a promising tool to detect and categorize prostate lesions. In this paper we review the role of radiomics applied to prostate mpMRI in detection and localization of prostate cancer, prediction of Gleason score and PI-RADS classification, prediction of extracapsular extension and of biochemical recurrence. We also provide a future perspective of artificial intelligence (machine …
Effect of Graphene Nanoplatelets on the Physical and Antimicrobial Properties of Biopolymer-Based Nanocomposites
2016
In this work, biopolymer-based nanocomposites with antimicrobial properties were prepared via melt-compounding. In particular, graphene nanoplatelets (GnPs) as fillers and an antibiotic, i.e., ciprofloxacin (CFX), as biocide were incorporated in a commercial biodegradable polymer blend of poly(lactic acid) (PLA) and a copolyester (BioFlex®). The prepared materials were characterized by scanning electron microscopy (SEM), and rheological and mechanical measurements. Moreover, the effect of GnPs on the antimicrobial properties and release kinetics of CFX was evaluated. The results indicated that the incorporation of GnPs increased the stiffness of the biopolymeric matrix and allowed for the t…

In vivo biodistribution and lifetime analysis of cy5.5-conjugated rituximab in mice bearing lymphoid tumor xenograft using time-domain near-infrared …
2008
Rituximab is a chimeric monoclonal antibody directed against human CD20 antigen, which is expressed on B-cell lymphocytes and on the majority of B-cell lymphoid malignancies. Herein we report the conjugate of rituximab with the near-infrared (NIR) fluorophore Cy5.5 (RI-Cy5.5) as a tool for in vitro, in vivo, and ex vivo NIR time-domain (TD) optical imaging. In vitro, RI-Cy5.5 retained biologic activity and led to elevated cell-associated fluorescence on tumor cells. In vivo, TD optical imaging analysis of RI-Cy5.5 injected into lymphoma-bearing mice revealed a slow tumor uptake and a specific long-lasting persistence of the probe within the tumor. Biodistribution studies after intraperiton…
