In many fisheries, some component of the catch is usually released. Quantifying the effects of capture and release on fish survival is critical for determining which practices are sustainable, particularly for threatened species. Using a standardized fishing technique, we studied sublethal (blood physiology and reflex impairment assessment) and lethal (post-release mortality with satellite tags...

The bull is a graph consisting of a triangle and two pendant edges. A graph is called bull-free if no induced subgraph of it is a bull. This is the last in a series of three papers. In this paper we use the results of [1, 2] and give an explicit description of the structure of all bull-free graphs.

Background: There currently is a lack of knowledge about the long-term survival of patients with beta thalassemia (BT), particularly in regions with low incidence of the disease. The aim of the present study was to determine the survival rate of the patients with BT major and the factors associated with the survival time.Methods: This retrospective cohort study was performed in Hamadan province...

Shelter staff and veterinarians routinely make subjective dog breed identification based on appearance, but their accuracy regarding pit bull-type breeds is unknown. The purpose of this study was to measure agreement among shelter staff in assigning pit bull-type breed designations to shelter dogs and to compare breed assignments with DNA breed signatures. In this prospective cross-sectional st...

The bull is the graph consisting of a triangle and two disjoint pendant edges. A graph is called bull-free if no induced subgraph of it is a bull. This is the first paper in a series of three. The goal of the series is to explicitly describe the structure of all bull-free graphs. In this paper we study the structure of bull-free graphs that contain as induced subgraphs three-edge-paths P and Q,...

the aim of this study was to determine the effects of the antioxidants superoxide dismutase (sod),glutathione peroxidase (gpx) and butylated hydroxytoluene (bht) on microscopic semen parameters andlipid peroxidation following the freeze-thawing of bull semen. ejaculates were collected from five holsteinbulls and pooled at 37°c. the semen samples were diluted with a cey extender containing addit...
