Harbor seals Phoca vitulina haul out on land to give birth to and rear their pups, rest, escape aquatic predation and molt. The choice of a haul-out site is therefore fundamental to survival and reproduction. Aerial surveys of harbor seals were conducted in Cook Inlet, Alaska, to investigate the seals’ selection of various environmental characteristics of haul-out sites. Eight surveys from Apri...

Due to economical and environmental issues, utilization of mineral wastes, e.g. iron ore mine tailing (IOMT), as road materials can be recommended as a sustainable alternative. In the present study, mechanical properties, as well as resistance to freezing and thawing cycles (F-T) of low plasticity clay soil stabilized with different percentages of Portland cement (0, 6, 9, 12 and 15%) and diffe...

GPS traces can track actual time and coordinates of regular vehicles going their own business, and it is easy to scale to the entire area with an accuracy of 6 to 10 meters in normal condition. As a result, extracting road map from GPS traces could be an alternative way to traditional way of road map generation. The basic idea of this paper is to describe a process which incrementally improves ...

Hauling out is an essential component of pinniped life-history. Haul-out behaviour may be affected by biological (e.g. sex, age and condition) and physical factors (e.g. food availability and environmental conditions), and identifying these factors may help explain the spatio-temporal distribution and habitat use of pinnipeds. The aim of this study is to describe observed winter haul-out patter...

Background. The double haul is a unique feature of single-handed fly casting and is used in both fly fishing and fly casting competition. The movement behaviour during the double haul has not been investigated in previous research. Objectives. Describe the coordination of the rod and line hauling movements during distance fly casting. Methods. Elite fly casters performed distance castin...

EU countries want to decarbonize their road freight transport quickly. Long-haul electric trucks are a promising technology. There several competing designs but at present the trade-off is between e-trucks with very large batteries and smaller battery combined motorways electrified via catenary lines. In latter case combination of public investment (catenary lines on major motorways) private (e...

The objective of this study was to characterize truck drivers’ activity concerning their work demands and challenges resulting from their work organization. The method applied was Collective Analysis of Work, which describes the activity based on the workers’ statements during their meetings with the researchers, focusing on factors that could be determinant for accidents and work-related disea...

Illegal drug smuggling hauls are displayed to the public, but destroyed after being used to prosecute the offenders. Computer viruses display themselves to computer users, everybody takes a copy for their collection, before killing off the in-situ infection(s). Effectively everybody is keeping their own drug haul. Virtually every serious PC user that gets near live virus specimens wants to have...
