De tal forma, para efectos de esta investigación se visitó las instalaciones de las plantas donde funciona el matadero y se estudió el tipo de los accidentes que pueden ocurrir en la planta tales como: Enfermedades profesionales por contaminación, riesgos para la salud por diversos cambios de temperatura, ruido, quemaduras, golpes por caídas, heridas punzó penetrantes etc. Por otra parte, según las estadísticas que maneja la empresa, los accidentes se presentan con mayor frecuencia en el turno de 7:00 a.m. a 12:00 p.m. que son horas claves para la matanza o beneficio de las aves.

Despite the rapidly growing popularity of laser in situ keratomileusis (LASIK) in correction of myopia, the tissue responses have not been thoroughly investigated. The aim was to characterize morphologic changes induced by myopic LASIK in human corneal stroma.

1] Extreme droughts may be characterized by their duration, severity (magnitude or intensity), spatial extent, and frequency or return period. Comparing the time series of water supply and water demand and analyzing droughts based on the theory of runs may determine these characteristics. This study is focused on drought analysis where the underlying water supply process is periodic stochastic, such as for monthly streamflows. The probability mass function (pmf) of drought length and associated low-order moments are derived assuming a periodic simple Markov chain. The derived pmf allows estimating the occurrence probability of droughts of a given length and its return period. The applicability of the drought formulations has been illustrated using a variety of water supply series such as monthly and weekly precipitation, monthly streamflows, the Palmer hydrologic drought index, and the standardized precipitation index. The results obtained confirm the validity of the analytical derivations for drought lengths and associated return periods. The overall conclusion of the study is that simple definitions of droughts enables one characterizing droughts using stochastic approaches and analytical derivations. They are particularly useful for drought analysis because the limited hydrologic records that are generally available do not allow observing many drought events of a particular duration and, in fact, extremely long droughts may not even be observable from the historical sample. This hinders the applicability of an inferential approach for finding the probability distributions of drought lengths and their associated return periods because it is either impractical or not feasible.

Los criterios de evaluación son los principios, normas o ideas de valoración en relación a los cuales se emite un juicio valorativo sobre el objeto evaluado. Deben permitir entender qué conoce, comprende y sabe hacer el alumno, lo que exige una evaluación de sus conocimientos teóricos, su capacidad de resolución de problemas, sus habilidades orales y sociales, entre otros aspectos.

Background: It has been suggested that the initial differentiation of endothelial and hematopoietic cells during embryogenesis occurs from a common progenitor, called hemangioblast (hB). We hypothesized that these cells with dual hematopoietic/ endothelial potential could be used in future regenerative medicine.
