Brinda información sobre las capturas del recurso anchoveta del año 1967/68, la cual indica que llegó a una cifra récord alcanzando 9'817,768 toneladas métricas del recurso. A su vez, menciona las ocurrencias que afectaron la comercialización del recurso, tales como: Paralización de fábricas, días de paro y día de vea del recurso por la temporada de verano.

Analiza la información hasta fines de marzo de 1969 sobre el recurso anchoveta, incluyendo datos sobre la magnitud de la nueva clase recluta de 1969, la intensidad en la aplicación del esfuerzo pesquero y la composición de las clases anuales en las capturas; con el fin de introducir mejoras en los cálculos de esfuerzo de pesca y conocer el tope de captura definitivo.

BACKGROUND: We hypothesized that polymorphic mutations exist that are associated with the emergence of the multinucleoside resistance mutations (MNR), 69 insertion and Q151M. METHODS: The Swiss HIV Cohort Study was screened, and the frequencies of polymorphic mutations in HIV-1 (subtype B) were compared between patients detected with the 69 insertion (n = 17), Q151M (n = 29), ≥2 thymidine analogue mutations (TAM) 1 (n = 400) or ≥2 TAM 2 (n = 249). Logistic regressions adjusted for the antiretroviral treatment history were performed to analyze the association of the polymorphic mutations with MNR. RESULTS: The 69 insertion and TAM 1 were strongly associated and occurred in 94.1% (16 of 17) together. The 69 insertion seemed to emerge as a consequence of the TAM 1 pathway (median years until detection: 6.8 compared with 4.4 for ≥2 TAM 1, P Wilcoxon = 0.009). Frequencies of 8 polymorphic mutations (K43E, V60I, S68G, S162C, T165I, I202V, R211K, F214L) were significantly different between groups. Logistic regression showed that F214L and V60I were associated with the emergence of Q151M/TAM 2 opposed to 69 insertion/TAM 1. S68G, T165I, and I202V were associated with Q151M instead of TAM 2. CONCLUSIONS: Besides antiretroviral therapy, polymorphic mutations may contribute to the emergence of specific MNR mutations.

The Iowa State Highway Commission has adopted a number of rigid safety requirements that the Bureau of Public Roads has set forth as standards for road construction. One of these safety requirements is the elimination of two piers on Interstate grade separations, thus leaving two long spans. These longer spans lower the ability of prestressed concrete beams to compete economically with steel beams. In an effort to be more competitive, the prestressing companies have been studying the use of lightweight aggregate in structural concrete.
