No full textGoing Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Evaluación de la viabilidad técnica y económica para la implementación de árboles líquidos en entornos urbanos e industriales
No full textPráctica Supervisada (I.Amb.)--FCEFN-UNC, 2024Fil: Lopez Zunino, Francisco Andres. Universidad Nacional de Córdoba. Facultad de Ciencias Exactas, Físicas y Naturales; Argentina.El presente informe, se centra en la evaluación de la viabilidad técnica y económica para la implementación de "árboles líquidos" en entornos urbanos e Industriales. La práctica supervisada se llevó a cabo en la empresa CEAS S.A. en Córdoba, en el marco de la carrera de Ingeniería Ambiental de la Facultad de Ciencias Exactas, Físicas y Naturales de la Universidad Nacional de Córdoba.
El trabajo se enfoca en una tecnología destinada a mitigar el cambio climático: el secuestro de carbono mediante fotobiorreactores de microalgas, conocidos como árboles líquidos. Estas estructuras capturan CO₂ atmosférico mediante fotosíntesis, con una eficiencia de captura entre 10 a 50 veces superior a la de las plantas terrestres. Además, la biomasa generada puede destinarse a la producción de biocombustibles, alimentos y productos de valor agregado.
Durante la práctica, se investigó el funcionamiento de estos sistemas, el marco normativo aplicable, y se diseñaron dos propuestas teóricas de fotobiorreactores: uno urbano (integrado en una parada de colectivo) y otro industrial (instalado en techos). El estudio incluyó el análisis de cepas de microalgas, eficiencia fotosintética, parámetros estructurales y estimaciones de rentabilidad.
Se concluye que la implementación local requiere investigación experimental adicional para evaluar la eficiencia real en el entorno, pero destaca el potencial de estas tecnologías para contribuir a la mitigación del cambio climático y mejorar la sostenibilidad urbana e industrial.Fil: Lopez Zunino, Francisco Andres.

The septin cytoskeleton is associated with distinct myelin structures of the central and peripheral nervous system
No full textRapid conduction of nerve impulses in the nervous system of higher vertebrates is made possible by ensheathment of nerve fibers by the specialized plasma membrane structure myelin. Consequently, failure of myelination or damage to the myelin sheath leads to severe pathology as seen in multiple sclerosis. During myelination oligodendrocytes and Schwann cells are challenged to build up and maintain a highly complex multilaminar plasma membrane structure. It is well-known that myelin membranes are divided into subdomains with distinct protein and lipid composition. Nevertheless, it is unclear how these domains are generated and then maintained throughout the adult. Especially the mechanisms of interaction between cytoskeleton elements and membrane structures in the developing and adult myelin sheath are still unknown. In this work, the interaction of the cytoskeleton protein septin(Sept6) and the myelin and lymphocyte protein MAL is demonstrated. Septins are enriched in myelin membranes which is unique for cytoskeleton elements. Most important, the loss of Sept6 in myelin is compensated by its closest homolog Sept11 which clearly points to a functional role of septins in the myelin compartment. A detailed analysis of the septin protein family in myelinating cells was performed here. It was shown that septins are coordinately regulated during differentiation and myelination in Schwann cells and oligodendrocytes. On the protein level particular septins were identified to be differentially enriched in myelin membranes. They form distinct stoechiometric complexes interacting also with actin. We propose that septin/myelin membrane complexes play an important role in myelination. Septins might be crucial in the formation and maintenance of myelin subdomains as well as in the transport of myelin components. In line with this, a possible site of interaction between Sept6 and MAL was identified in the Schwann cell cytoplasm. There, Sept6 and MAL might be important for sorting and trafficking processes crucial for the targeting of myelin components into the emerging and adult myelin sheath. Sept6-deficient mice, however, did not disclose alterations in myelin ultrastructure and protein composition besides the upregulation of Sept11. But, it is well-known that the septin cortex is very robust and that homologous isoforms might compensate for the loss of single septins. In line with this, it is shown here that myelinating Schwann cells tolerate the loss of Sept2, which might be due to such compensation mechanisms. The function of Sept7 in myelination could not be elucidated, since downregulation in in vitro myelinating cultures led to unspecific effects probably on cytokinesis and cell survival. Nevertheless, this first comprehensive study on septins in oligodendrocytes and Schwann cells generated valuable data critical for further analysis of septin function in myelin. This study provides insight into the composition of the septin cytoskeleton, its regulation during myelination and its interaction with myelin membranes. Understanding the role of the septin cytoskeleton in myelin formation and maintenance may reveal new insights in the mechanisms of myelination and remyelination in health and disease
