Resumen. En este artículo se aplica la metaheurística de colonia de hormigas (ACO) para resolver el problema de ruteo que se presenta al realizar la tarea de recolección de residuos sólidos en UNAM-CU. Este espacio está dividido en varios circuitos de los cuales el circuito CCU será nuestro primer caso de estudio. El encontrar la mejor ruta para este circuito, puede verse como un problema de op...

Suspension cultures of Rosa sp., soybean (Glycine max L.), wheat (Triticum monococcum L.), sweet clover (Melilotus alba Desc.), Haplopappus gracilis Nutt., and rue (Ruta graveolens) produced ethylene. The amount varied with the species. The rate of formation in rose and Haplopappus cells paralleled growth but accelerated when the stationary phase was reached, after which the rate declined sharp...

Increasing evidence indicates that there is ample diversity of plant virus species in wild ecosystems. The vast majority of this diversity, however, remains uncharacterized. Moreover, in these ecosystems the factors affecting plant virus infection risk and population genetic diversity, two traits intrinsically linked to virus emergence, are largely unknown. Along 3 years, we have analyzed the p...

The first syntheses of two quinoline alkaloids found in the medicinal herb Ruta chalepensis are reported via the conjugate addition of an o-iodoaniline to an acetylenic sulfone, followed by Pd-catalyzed carbonylation, intramolecular acylation of the corresponding sulfone-stabilized carbanion, and reductive desulfonylation.

The aim of the present study was to investigate the chemical composition and antioxidant activity of Satureja montana essential oil of Romanian origin (S. montana EO). The essential oil was obtained by hydrodistillation from dried aerial parts of cultivated plants in northeastern Romania. The chemical composition of S. montana EO was analysed by GC and GC-MS. The main compounds were carvacrol (...

This paper contains first systematical revision of the results on traditional use of wild medicinal and aromatic herbs on the territory of Bosnia and Herzegovina (B&H)--west of Balkan Peninsula; Southeast of Europe. There have been detected 227 plants belonging to 71 different plant families, which are being used with ethno therapeutic purpose. Results were obtained by method of open ethno bota...

U radu je izvršena optimizacija rute kurira. Ruteranjem određeno više putanja kretanja na osnovu definisanih zahteva korisnika, kako bi se došlo do optimalnog rešenja minimlalnih troškova transporta, minimalno utrošeno vreme, najkraće i najbrže rute, kao smanjenje emisije štetnih gasova dobijanje ekonomičnijeg vozila.

Five persons contracted tick-borne relapsing fever after staying in a cabin in western Montana. Borrelia hermsii was isolated from the blood of two patients, and Ornithodoros hermsi ticks were collected from the cabin, the first demonstration of this bacterium and tick in Montana. Relapsing fever should be considered when patients who reside or have vacationed in western Montana exhibit a recur...
