Type specimens housed in the herpetological collections at Museo de La Salle Bogotá and their historical importance for the consolidation of herpetology in Colombia
No full textWe present a catalog of type specimens deposited in the Herpetological collections at the Museo de La Salle (MLS), Bogotá, Colombia. The list includes 85 type specimens comprising 36 holotypes and 49 paratypes. Also, we include the types belonging to other institutions, corrections in the catalog numbers and localities, additions and updates to the information in the original descriptions, as well as rediscovery of material that was considered lost until now
Reference values for acid-base parameters in healthy mules at high altitude
No full textReference intervals (RI) of physiological parameters related to the acid-base equilibrium state were estimated from blood samples of 76 healthy mules at high altitude. The animals were at rest and subjected to the same diet. The data obtained were compared with those reported by various authors, finding closeness between the estimated RIs and those of the cited authors. It was concluded that the RI of mules and horses do not present great differences
The impact of the work environment on innovation and business sustainability in SMEs: The case of San José de Cúcuta, Colombia
No full textInnovation is a process, where the interpersonal relationships of employees are key to the creation of ideas that will contribute to the generation of value for organizations in the face of disruptive environments. This chapter analyzes the relationship between the work environment as a key factor and its impact on the development of innovation processes and business sustainability, taking as a sample 182 SMEs, from commercial, footwear, and textile sectors from the city of Cúcuta. The results showed an interrelation between the organizational climate and the culture of innovation as an agent that generates change that contributes to business sustainability
Spatial distribution and chemical composition of road dust in two high-altitude latin american cities
No full textRoad dust (RD) resuspension is one of the main sources of particulate matter in cities with adverse impacts on air quality, health, and climate. Studies on the variability of the deposited PM10 fraction of RD (RD10) have been limited in Latin America, whereby our understanding of the central factors that control this pollutant remains incomplete. In this study, forty-one RD10 samples were collected in two Andean cities (Bogotá and Manizales) and analyzed for ions, minerals, and trace elements. RD10 levels varied between 1.8–45.7 mg/m2, with an average of 11.8 mg/m2, in Bogotá and between 0.8–26.7 mg/m2, with an average of 5.7 mg/m2, in Manizales. Minerals were the most abun-dant species in both cities, with a fraction significantly larger in Manizales (38%) than Bogotá (9%). The difference could be explained mainly by the complex topography and the composition of soil derived from volcanic ash in Manizales. The volcanic activity was also associated with SO4⁻2 and Clˉ. Enrichment factors and principal component analysis were conducted to explore potential factors associated to sources of RD10. Elements such as Cu, Pb, Cr, Ni, V, Sb, and Mo were mainly associated with exhaust and non-exhaust traffic emissions
Production and quality of forage of Sambucus nigra in living fences, high Colombian tropics
No full textIntroduction. Livestock feeding in Colombian high tropic livestock systems is based on monoculture grass grazing of low quality and low biomass during drought periods, which affects the productive performance of the animals. Objective. To evaluate the production and nutritional quality of forage of Sambucus nigra L., established as a silvopastoral live fence arrangement. Materials and methods. The research was carried out at the San Joaquin farm, located in Paipa, Colombia; the samplings were done between January 2019 and March 2020. In a live fence arrangement, a 226 m linear transect was selected, in which 17 trees were randomly selected. The green forage and dry matter production of the complete plant and its fractions (leaves and stems), the leaf - stem ratio and the nutritional quality (NIRS) of the complete plant and of each fraction were evaluated. A randomized design was carried out, descriptive statistics and analysis of non-parametric variance (Kruskal Wallis test) were performed for forage production and leaf-stem relationship, the data analysis was done using the Infostat® program. Results. The production of green forage and dry matter was 19, t km-1 year-1 and 3,9 t km-1 year-1, respectively. There were differences (p\u3c0.0001) in nutritional quality, the leaves were of higher quality, the forage had a high crude protein content, metabolizable energy and digestibility, low percentage of neutral detergent fiber and acid detergent fiber, the leaf-stem ratio was 0.8: 1, although there were differences between samplings (p\u3c0.0001). Conclusions. The living fences of S. nigra produced high production of edible biomass per kilometer per year, the forage of the complete plant and its fractions had good nutritional quality, crude protein, energy, and digestibility
Reciclaje de la arquitectura en centros de ciudad. Estudios de caso-hoteles y patrimonio en Colombia
No full textReciclaje de la arquitectura en centros de ciudad analiza, por medio de estudios de caso, el potencial que tienen variados proyectos arquitectónicos en Colombia al trabajar de esta manera tendencias como la reutilización de materiales, que sigue ganando espacio y relevancia en la industria de la arquitectura y la construcción. En el texto se estudia esta práctica en lugares tan variados como un monasterio o una vivienda, localizados en los centros históricos y convertidos por azar del destino en hoteles que impactan de manera grata las ciudades al favorecer una dinámica para el turismo y la sostenibilidad, revitalizando el entorno mediante la adecuación, la actualización, la restauración y la refuncionalización, en últimas: ¡El reciclaje para el disfrute de la ciudad como tendencia de los inmuebles patrimoniales!https://ciencia.lasalle.edu.co/edunisalle_arquitectura-urbanismo/1014/thumbnail.jp
Diagnóstico al reflujo en el sistema de alcantarillado pluvial y sanitario en el barrio isla del sol
No full textEl presente trabajo tiene como finalidad identificar la causa por la cual actualmente se presenta reflujo en el sistema de alcantarillado del barrio Isla del Sol encontrándose este colindante con el río Tunjuelo, para lo anterior se determinó las condiciones actuales del sistema de alcantarillado del barrio Isla del Sol, por ende se empleó la metodología establecida en el reglamento técnico del sector de agua potable y saneamiento básico (Resolución 0330 de 2017), de igual manera se estableció la interacción comprendida entre la descarga del sistema de alcantarillado tanto pluvial como sanitario con los niveles del río Tunjuelo, así mismo se empleó el software EPA SWMM con el fin de determinar las condiciones críticas de operación del sistema de alcantarillado
