Gray Wolf Conservation at a Crossroads

Captivity for Conservation? Zoos at a Crossroads

Use of gray wolf algorithm to optimize gas microturbineUse of gray wolf algorithm to optimize gas microturbine

 In this research, optimization of gas microturbine through economic, exergy and environmental analysis has been investigated by the gray wolf algorithm. First, a thermodynamic modeling was performed for each of the above modes, and then using the gray wolf method, optimum points were determined for each systemchr('39')s performance. For modeling, the code written in MATLAB software was used. ...

Management and Conservation Monitoring Gray Wolf Populations Using Multiple Survey Methods

The behavioral patterns and large territories of large carnivores make them challenging to monitor. Occupancy modeling provides a framework for monitoring population dynamics and distribution of territorial carnivores. We combined data from hunter surveys, howling and sign surveys conducted at predicted wolf rendezvous sites, and locations of radiocollared wolves to model occupancy and estimate...

Colposcopy at a crossroads.

New cervical cancer prevention strategies are arising from rapidly improving insight into human papillomavirus (HPV) natural history and cervical carcinogenesis, challenging the conventional roles of cytology and colposcopically directed biopsy as the reference standards of screening and diagnosis, respectively. HPV testing has high sensitivity but mediocre specificity and positive predictive v...

How the gray wolf got its color.

The footpad at the bottom is about 1 meter below the spacecraft deck seen at the lower left. Overlaid images are trenches dug to either nearly pure water ice or ice-cemented soil. Analyses of samples taken from these trenches give clues to the history of the region. Results...
