The present study reports the age, growth, and reproduction parameters of 52 brown rays (Raja miraletus) captured from Saros Bay (Northern Aegean Sea) between September 2006 -2008. males females accounted for 44.2% 55.8% sample, respectively. measured 10.5-53.5 cm (disc width, 6.5-32 cm) ranged 25.5-47.7 18-30.5 in total length (TL). equations TW=0.0017*TL3.27 TW=0.0017*DW3.38 were used to desc...

successful development, evaluation, and qualification of propulsion systems such as turbojet and turbofan engines and rocket motors require the measurement of the performance and reliability of these systems. thrust stands or testers are instruments for solid and liquid motors test. in this paper, a method for calculating of solid motors random vibrations effects on a thrust stand structure is ...

To understand the fluid dynamics of a biologically inspired unsteady low-aspect-ratio propulsor, unsteady pressure distributions were measured and compared with time-averaged thrust performance and wake visualizations. The experiments were performed on rigid rectangular panels with different aspect ratios, pitching in a uniform flow. Panel aspect ratio and pitching amplitude were shown to affec...

Estimation of genetic parameters is the most important component of an organized selection program. With respect to economic traits, such as wool and mutton traits, production costs can be reduced through a suitable selection program focused on genetic improvement. This study aimed to evaluate genetic parameters of fleece and post-weaning growth traits in sheep. Greasy fleece weight at 6, 16, 2...

PURPOSE To report the four-year experience of the Stanford University Network for Diagnosis of Retinopathy of Prematurity (SUNDROP) telemedicine initiative, which was developed to reduce the risk of blindness from retinopathy of prematurity (ROP). MATERIALS AND METHODS A retrospective analysis of the SUNDROP archival data between 12/1/2005 and 11/30/2009. A total of 410 consecutively enrolled...

Two experiments were conducted to evaluate the effects of drinking water temperature (Tw) on laying hens subjected to warm cyclic air temperature (Ta) conditions. Each experiment consisted of a 1-wk acclimation under thermoneutrality (TN) (Ta = Tw = 21 C), a 4-wk heat exposure or treatment period, and a 2-wk recovery under TN. Each experiment involved 24 individually caged hens at the initial a...

The ratio of the largest eigenvalue divided by the trace of a p×p randomWishart matrix with n degrees of freedom and identity covariance matrix plays an important role in various hypothesis testing problems, both in statistics and in signal processing. In this paper we derive an approximate explicit expression for the distribution of this ratio, by considering the joint limit as both p, n → ∞ w...
