Stock assessment of Otolithes ruber was carried out using Virtual Population Analysis (VPA) method in the coastal waters of Northwest area of the Persian Gulf. Catch and length frequency data during 2002-2012 were converted to age frequency. The maximum of stock number and biomass were observed in age group 1 and 2, respectively. The minimum stock number and biomass were observed for age group ...

Background. The goal of our research was to assess overweight as a risk factor for reduced survivability of Weller-type artificial cement hip joints. Material and methods. We studied 71 patients (26 men, 45 women) diagnosed with aseptic loosening of Weller endoprostheses. The age of the patients ranged from 62 to 87 years of life (mean 74.3 +/- 6.0), the exploitation time of the artificial hip-...

Jensen, A.L., 1991. Simulation of fish population responses to exploitation. Ecol. Modelling, 55: 203-218. A model that couples Larkin's predator-prey model, Ivlev's feeding model, Ursin's growth equation and the exponential mortality model was applied for simulation of the responses of fish populations to exploitation. Simulations were done without food-limited growth, with food-limited growth...
