A case study of the Ottawa Valley whitewater rafting industry : standards and risks
… practices of the Ottawa Valley whitewater rafting industry and the impacts of the government enforced Special-purpose Vessels Regulations are discussed. Data collection occurred using a single case study design, which included interviews and document analysis. This study found that …

Numerical determination of forces acting on material interfaces : an application to rafting in Ni-superalloys
Thesis (M.S.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 1990.

Hydropeaking in Alpine rivers: an ecosystem services approach
… of a discharge-related ecosystem service, the rafting. The application of hydraulic and habitat models allowed to define spatially thresholds of suitability in each river reach and the application of an hydrological model allowed to assess temporally the suitability for the rafting navigability …

Floating seaweed as ephemeral neustonic habitat
… fauna to new, distant locations by means of rafting. The process of rafting strongly depends on the longevity of the seaweed raft, which is in turn significantly influenced by temperature and grazing pressure. In favourable conditions, seaweed rafts can potentially cover great distances, …

An experimental investigation of the effects of perceived co-consumer age on younger consumers' expectations of service quality
… was conducted where three service settings (rafting trips, restaurants, classrooms) and three categories of co-consumer age (young, middle-aged, old) were manipulated using a student sample of two hundred and forty-three. Across the three services studied, younger consumers' expectations of …

Sedimentologic and Stratigraphic Significance of Boulder Layers in the Outer Coastal Plain of Southeastern Virginia
… boulders in the boulder layers. Winter river-ice rafting might provide a possible means of transporting the larger and angular clasts from the Blue Ridge and Piedmont Provinces to the boulder layers in southeastern Virginia. Reproduced</p>

Analysis and modelling of the dislocation response during non-isothermal creep in Ni-SX superalloys
… test cycle varying between the tertiary and rafting creep regimes. For this purpose, creep tests cycling between a base temperature of 900 ◦C and a peak temperature of 1050 ◦C under a constant load (σ = 200 MPa) were carried out and the samples were subse- quently analyzed using TEM …

Perceived risk in adventure tourism
… adventure tourism activities (whitewater rafting, bungy jumping, and sailing). It was found that prior experience in the given activity did not present itself as a factor that lowered risk as a motivation, that no motivational differences existed between nationalities, and that varying …

Influence of surface hardening on single crystal nickel-based superalloys
… those treated by MSP. Directional coarsening, or rafting, of the γ/γ' microstructure was noted at 1100 °C. The extent of rafting was independent of the hardening conditions, and increased with depth before reaching a transition to the bulk microstructure. It was surmised that rafting was driven by …

An Examination of the Relationship Between Adventure Recreation and Adolescent Identity Development
… and environmental education) and white water rafting. The quantitative results supported the hypothesis that the adventure recreation program would promote positive adolescent identity development. The data also indicated only limited differences between the developmental impact of the program …

The Archaeology of Travel in Greater Nicoya (500 BC – AD 1250)
… Rica. Traveling across land and canoeing or rafting over the large freshwater lakes and rivers, these peoples voyaged for many hours to trade goods and maintain social and political ties with their neighbors. The range and frequency of these interactions within this region is demonstrated by …

Investigating sediment size distributions and size-specific Sm-Nd isotopes as paleoceanographic proxy in the North Atlantic Ocean: reconstructing past deep-sea current speeds since Last Glacial Maximum
… (bottom currents, turbidity currents, ice-rafting events, airborne inputs) can be well distinguished through the size-specific physical and geochemical records. When primarily advected by the bottom currents, Holocene sediments show that the finer-sized fractions (0–4, 4–10, 10–20 µm) were …

Modelling sea ice floe fields
… and redistribution processes such as ridging and rafting. Daily wind and temperature data together with long term ocean currents are used as input to drive the model. The results of a six month simulation of the sea ice development in the (Eas t) Greenland region are presented and discussed …

Modern sedimentation in the Northern Barents Sea : input, dipersal and deposition of suspended sediments from glacial meltwater
… Minor additional sediment is supplied by iceberg rafting englacial material and sea-ice containing aeolian, resuspended, and beach sediments. Glacial flour is supplied by several large stable meltwater outflow locations along the ice front. Because the water is fresh and nearly the same …

Sedimentology and micropalaeontology of gravity cores from the N.E. Atlantic continental slope south west of Ireland
… of several different physical processes e.g. ice-rafting, contour currents etc. Striking variations in the populations of planktonic foraminifera were noted, alternating between Arctic and Sub-Arctic assemblages, reflecting the waxing and waning of glacial activity. The coccolith-carbonate minima …
