GENETIC DIVERSITY WITHIN AND BETWEEN BROODSTOCKS OF THE WHITE SHRIMP LITOPENAEUS VANNAMEI (BOONE, 1931) (DECAPODA, PENAEIDAE) AND ITS IMPLICATION FOR THE GENE POOL CONSERVATION

Genetic diversity within and between broodstocks of the white shrimp Litopenaeus vannamei (Boone, 1931) (Decapoda, Penaeidae) and its implication for the gene pool conservation

Genetic variation within and between fifteen closed broodstock lines of the Pacific white shrimp Litopenaeus vannamei, reared at different hatcheries in the Brazilian coast, was assessed by RAPD analysis.Fifty two polymorphic loci were identified when a set of five decamer primers was used in PCR.The genetic diversity analysis within lines evidence

Last train timetabling with transfer accessibility in metro networks: integer linear programing model and schedule-based transfer network

Last train timetable plays Sauces an important role in actual operation of metro systems, especially in big cities.Appreciable transfer passengers rely on last train connections to reach their destinations, which requires a coordinated last train timetable.This study is devoted to dealing with the last train timetabling problem in metro networks, a
