MonthlySpawning Stock and Egg Production of Peruvian Anchoveta (Engra~/is ringens), 1953 to 1982*
Available data on the reproductive biology of the Peruvian anchoveta (ElIgrauJis ringens, nonhem/caltral stock, 4-1405) are reviewed and lUed to estimate monthly spawning size and egg production iran January 1953 to December 1982. Basic information used are: (a) monthly biomass by length class (4 to 20 em), (b) a model relating the shape and position of the matUration ogive to sea surface tcnpe...
متن کاملDairy Cattle by Exploiting Progeny Testing
We have exploited “progeny testing” to map quantitative trait loci (QTL) underlying the genetic variation of milk production in a selected dairy cattle population. A total of 1,518 sires, with progeny tests based on the milking performances of > 150,000 daughtersjointly, was genotyped for 159 autosomal microsatellites bracketing 1645 centimorgan or approximately two thirds of the bovine genome....
متن کاملPerformance Evaluation of Tehran Subway Stations
Efficiency evaluation is one of the major issues in urban transportation. Since the efficiency of the systems is affected by its data and output, what makes the results of the performance evaluation valid and applicable, is selecting the appropriate data and outputs of the system. In this study, the efficiency of the subway stations in Tehran in case of return, compared to the fixed scale, is m...
متن کاملUsing LIDAR to Validate the Performance of Vehicle Classification Stations
Vehicle classification is an important traffic parameter for transportation planning and infrastructure management. Vehicle classification stations depend on accurate calibration and validation to yield meaningful results. Operating agencies spend millions of dollars to deploy vehicle classification stations to collect classified count data, yet very few of these stations are ever subjected to ...
متن کاملoptimization of progeny testing programs for iranian holstein dairy cattle
a deterministic model was employed to simulate various progeny testing programs compatible with the conditions of holstein dairy cattle population in iran. in simulated programs, the selection intensity of bulls was increased by increasing the ratio of cow population in mate with young bulls. selection accuracy in the programs was fixed because of the fixed progeny group. economic efficiency (t...
