Length composition data of narrow-barred Spanish mackerel, Scomberomorus commerson (Lacepede 1800), landed between April 2002 to March 2004, were monthly used to estimate the growth, mortality and exploitation parameters of the stock. Maximum fork length and weight were 170 cm and 38 kg, respectively. Nonlinear least square fitting provided a complete set of von Bertalanffy growth estimates: L¥...

Medical interviewing has evolved considerably during the last 35-50 years. Nowhere has progress been greater than with the articulation of the interview's endpoint, the biopsychosocial model (Engel, 1977b; 1980). Interviewers collect personal information and physical symptoms from the patient and, then, synthesize these data to produce a biopsychosocial description — the patient's story. We gen...

This paper presents the results of study on age, growth, mortality rates and yield-per-recruit of Beluga (Huso huso) living in Caspian Sea. The mean length of successive years, mortality rates and yield-per-recruit studies indicated that at present the resource is under heavy fishing pressure. For the female Beluga growth was regarded as comprising of three stages, and the von Bertalanffy param...

Age and growth of the European barracuda, Sphyraena sphyraena, were determined by examining sagittal otoliths belonging to fish sampled in eastern Adriatic Sea, as northernmost region Mediterranean. A total 113 specimens (59 females, 53 males, one individual indeterminate sex), ranging from 23.4 42.5 cm length, analyzed. The maximum observed age was 5 years for both females this barracuda popul...

This study aimed to fit nonlinear regression models model the growth of characters fruit length (FL) and width (FW) pepper genotypes (Capsicum annuum L.) over time using method ordinary least squares (OLS); identify with best compare it obtained via quantile (QR) in 0.25, 0.5, 0.75 quantiles. Three (Logistic, Gompertz, von Bertalanffy) four quality evaluators were adopted: Akaike information cr...

In this paper we study optimal animal movement in heterogeneous environments consisting of several food patches in which animals trade-off energy gain versus predation risk. We derive a myopic optimization rule describing optimal animal movements by fitness maximization assuming an animal state is described by a single quantity (such as weight, size, or energy reserves). This rule predicts a cr...

in order to determine the age structure, growth, and length-weight relationship of the mudskipper, periophthalmus waltoni, from coastal mudflats of qeshm island, soroo and bandar-pol, in hormuzgan province, iran, we collected 192 individuals in february 2007. age was determined using the second pectoral radial bone and year class was based on length-frequency distributions. growth was descr...

Growth curves are useful for describing the sigmoid shape of an animal's weight pattern over time. The purpose of the present study was to describe, for the first time, a complete growth curve for pasture-fed Angus cows in Uruguay and to analyze the major fixed effects that affect the estimation of mature cow weight (CW). A total of 22,743 records from 5,284 cows belonging to 73 herds were used...
