Aerial-trained deep learning networks for surveying cetaceans from satellite imagery.

Most cetacean species are wide-ranging and highly mobile, creating significant challenges for researchers by limiting the scope of data that can be collected and leaving large areas un-surveyed. Aerial surveys have proven an effective way to locate and study cetacean movements but are costly and limited in spatial extent. Here we present a semi-automated pipeline for whale detection from very high-resolution (sub-meter) satellite imagery that makes use of a convolutional neural network (CNN).

[Immunopathogenetic features of occupational bronchitis].

The article based on research work covers functional, bronchoscopy, microbiologic and immunologic features of chronic dust bronchitis and chronic bronchitis caused by toxic chemicals.

[Definition of rate of biological aging at vibration disease].

The article presents results of definition of biological aging rate at vibration disease caused by the influence of local and general vibration, at I and II stage of disease; a role of vibrating influence in acceleration of biological aging of people working in the conditions of vibration is underlined.

Not all songbirds calibrate their magnetic compass from twilight cues: a telemetry study.

Migratory birds are able to use the sun and associated polarised light patterns, stellar cues and the geomagnetic field for orientation. No general agreement has been reached regarding the hierarchy of orientation cues. Recent data from naturally migrating North American Catharus thrushes suggests that they calibrate geomagnetic information daily from twilight cues.

[Health preservation for working population: problems and optimization methods].

The article deals with problems and ways to optimize health protection for working population. The authors stress the problems reducing quality of periodic medical examinations, of health state of working population. Notion is that nowadays employers, employees and medical officers are not interested in better work conditions and qualitative periodic medical examinations.
