Guinea-pig spermatozoa in the presence of a purified fraction from Echeveria gibbiflora aqueous crude extract suffer a hypotonic-like effect. The phenomena exhibited included a distension of the plasma membrane over the acrosome region, inducing the formation of a huge 'head-bubble'. The agglutination effect was so enhanced that instead of inducing sperm clusters, it produced cane-like 'stalk' structures. The immobilizing activity was induced instantaneously after the addition of the purified fraction. ...

This work deals with finite time observability of switched linear systems ( SLS ) when they are represented by a family of nonautonomous linear systems ( LS ) and an interpreted Petri net ( IPN ). Based on this SLS representation, new detection of the commutation time and LS distinguishability characterizations in SLS extended to the non autonomous case are presented. Using these results, the novel concept of distinguishability between LS sequences is presented and characterized. This concept together with the ...

Tomato brown rugose fruit virus (ToBRFV) is an emerging pathogen affecting tomato-production systems in several countries, including Mexico. This situation involves challenges due to the negative impact on yield and the lack of disease-management measures. This work analyzes the spatiotemporal distribution of ToBRFV in commercial tomato greenhouses. The presence or absence of diseased plants was evaluated weekly, assigning a location in space (x, y). Temporal analysis consisted of fitting the incidence ...

Phytophthora cinnamomi is the most important pathogen in avocado crops that causes the disease named avocado root rot (PRR). This disease affects the root system and induces multiple symptoms that end with plant death and causes large economic losses. PRR management is based almost exclusively on the use of fungicides (metalaxyl and phosphites). This situation led to inefficient management practices with apparently satisfactory results only in short periods. The objective of this work was to evaluate ...
