Análisis de diez sistemas secuenciados que forman la estructura del mundo y proporcionan una visión única de su funcionamiento básico. Desde diagramas que muestran las relaciones entre el espacio y el tiempo hasta los comportamientos cuanticos que rigen la interaccion entre la materia y la luz. Con explicaciones sobre la radiacion de fondo de microondas, los diagramas sobre la naturaleza entrelazada del espacio y el tiempo, los patrones de las rutas que siguen las particulas, los patrones que predicen el comportamiento cuantico, la tabla periodica que refleja el patron subyacente en la configuracion de los atomos, un analisis de la recta numerica o los usos descriptivos de los diagramas de arbol, entre muchas otras cosas. Nuestro universo puede parecer caotico, pero en el fondo tan solo consta de una miriada de reglas que funcionan de forma independiente para crear los patrones de accion, de fuerza y de consecuencia. En este libro se exploran los fenomenos que forman la estructura misma de nuestro mundo mediante el examen de diez sistemas secuenciados fundamentales.

Este libro es resultado de un trabajo de investigación para optar al título de Licenciado en Biotecnología. El mismo se centró en la optimización de la producción de sideróforos a partir de bacterias de suelo y ensayar la aplicacion in vitro de estos y de las cepas que los producen, en el control biologico de hongos fitopatogenos. Se partio del aislamiento y seleccion de cepas bacterianas con potencial de producir sideroforos (compuestos extracelulares que solubilizan hierro) a partir de muestras de suelo vitivinicola. Las cepas seleccionadas fueron sometidas a diversas condiciones de cultivo, evaluando diferentes fuentes de carbono y nitrogeno y distintos tiempos de incubacion buscando maximizar la produccion de sideroforos. Posteriormente, los compuestos obtenidos y las bacterias productoras fueron ensayadas contra diferentes hongos fitopatogenos, buscando demostrar la capacidad inhibitoria del crecimiento fungico mediante diferentes ensayos in vitro. Este trabajo propone estudiar tanto a los sideroforos como herramientas prometedoras para el control biologico de hongos, como su produccion en distintos medios de cultivo. El presente trabajo final se ha realizado como una continuacion de los estudios llevados a cabo durante una pasantia y beca de investigacion previas. Al mismo se lo ha estructurado en tres capitulos principales. Cada uno describe los metodos, materiales y resultados de los ensayos realizados, junto con sus respectivas conclusiones.

Muchos estudiantes perciben la termodinámica química como una disciplina abstracta y desconectada de la vida cotidiana. Este libro, basado en un enfoque didáctico innovador, busca cambiar esa percepcion. Los autores presentan una introduccion clara y accesible a las dos magnitudes fundamentales de esta rama de la fisicoquimica: la entropia y, especialmente, el potencial quimico. Las consideraciones teoricas se integran con experiencias cotidianas en mas de ochenta experimentos demostrativos, muchos de los cuales estan disponibles en linea en formato de video. Diseñado principalmente para estudiantes de primer año de universidad, el texto requiere unicamente conocimientos matematicos basicos, convirtiendose en una puerta de entrada a esta fascinante area de la quimica.
