In many polygynous ruminant species, males decrease their food intake considerably during the rut. To explain this phenomenon of rut-reduced hypophagia, two main hypotheses, the Foraging-Constraint Hypothesis and Energy-Saving Hypothesis, have been proposed. In our research, we assessed the behavioral strategy of goitered gazelles (Gazella subgutturosa) through the rutting period. According to ...

AbstractThis paper characterized field rutting performance of asphalt pavement based on Hamburg wheel tracking (HWT) rut depth. The depths were collected from 50 sections, and co...

BACKGROUND The rapid urease test (RUT) is used at Groote Schuur Hospital for diagnosing Helicobacter pylori infection. This is an in-house method, which has not been validated. OBJECTIVE To validate our practice of reading the RUT immediately after endoscopy (RUT(0)), by comparing this with a reading at 24 hours (RUT(24)) and with histological analysis. DESIGN Ninety consecutive patients un...

Rutaecarpine (RUT), the major bioactive ingredient isolated from the Chinese herb Evodia rutaecarpa, possesses a wide spectrum of biological activities, including anti-inflammation and preventing cardiovascular diseases. However, its high cytotoxicity hampers pharmaceutical development. We designed and synthesized a derivative of RUT, bromo-dimethoxyrutaecarpine (Br-RUT), which showed no cytoto...

The present study evaluated the effect of rutaecarpine (Rut) on Cl(-) secretion across rat distal colonic mucosa. Basolateral application of Rut elicited an increase in short-circuit current (I(SC)) response in a concentration-dependent manner. Evidence that Rut-stimulated I(SC) was due to Cl(-) secretion is based on 1) inhibition of current by bumetanide; 2) Cl(-) channel blockers diphenylamin...

Flexible pavements comprise about 93 percent of paved roads in the United States. Although flexible pavements are widely used for reasons such as cost, constructability and consistent performance, they are often subject to severe rutting. Rutting is the accumulation of longitudinal depressions under the wheelpaths caused by the repeated traffic loads. Rut is a major concern for the integrity of...

The optimization of a pavement management system necessitates the knowledge on the actual values of pavement condition parameters, actual pavement condition improvement as related to the use of various rehabilitation strategies, and scope of pavement deterioration before and after rehabilitation. The data for six pavement condition parameters (bearing capacity, unevenness, rut depth, macro text...
