Objective- To find out the best choice for complete recovery of digital dermatitis using four individual topical treatments.Design- clinical field trial.Animal- 550 dairy cows.Procedure- The trials were begun in March and finished in August 2005 in a dairy farm including 550 milking cows in the vicinity of Tehran .The prevalence of digital dermatitis (DD) was 23%. 126 cows with DD were selected...

We develop a general approach to robust inference about a scalar parameter when the data is potentially heterogeneous and correlated in a largely unknown way. The key ingredient is the following result of Bakirov and Székely (2005) concerning the small sample properties of the standard t−test: For a significance level of 5% or lower, the t−test remains conservative for underlying observations t...

The significance of tidal interactions in the evolution of the faint radio population (sub-mJy) is studied using a deep and homogeneous radio survey (1.4GHz), covering an area of 3.14deg and complete to a flux density of 0.4mJy. Optical photometric and spectroscopic data are also available for this sample. A statistical approach is employed to identify candidate physical associations between ra...

Background and objectivesPositive surgical margin (PSM) after radical prostatectomy (RP) is an established factor associated with the outcome of biochemical recurrence (BCR). Dominant tumor presumed to harbor most aggressive biological behavior. The aim this study was evaluate clinical significance PSM laterality its correlation dominant tumor.
