A Development/Management Plan for Cape Scott Provincial Park
No full textThis project was undertaken in January, 1980, and was continued right through until its completion in April, 1981. During this time, a vast quantity of information was compiled, through literature, personal contact, and through personal experience. The entire summers of 1977 and 1980 were spent in the field at Cape Scott for the author to familiarize themselves with the park and to collect field data. Also during this period, a tremendous feeling for the needs of the public and the needs of the park were acquired. It is hoped that the following will provide a compromise between these two factors.Student paper for Wildland Recreation, Selkirk College.Wildland Recreatio
Design of distributed JT (Joule-Thomson) effect heat exchanger for superfluid 2 K cooling device
No full textSuperfluid at 2 K or below is readily obtained from liquid helium at 4.2 K by reducing its vapour pressure. For better cooling performance, however, the cold energy of vaporized helium at 2 K chamber can be effectively utilized in a recuperator which is specially designed in this paper for accomplishing so-called the distributed Joule-Thomson (JT) expansion effect. This paper describes the design methodology of distributed JT effect heat exchanger for 2 K JT cooling device. The newly developed heat exchanger allows continuous significant pressure drop at high-pressure part of the recuperative heat exchanger by using a capillary tube. Being different from conventional recuperative heat exchangers, the efficient JT effect HX must consider the pressure drop effect as well as the heat transfer characteristic. The heat exchanger for the distributed JT effect actively utilizes continuous pressure loss at the hot stream of the heat exchanger by using an OD of 0.64 mm and an ID of 0.4 mm capillary tube. The analysis is performed by dividing the heat exchanger into the multiple sub-units of the heat exchange part and JT valve. For more accurate estimation of the pressure drop of spirally wound capillary tube, preliminary experiments are carried out to investigate the friction factor at high Reynolds number. By using the developed pressure drop correlation and the heat transfer correlation, the specification of the heat exchanger with distributed JT effect for 2 K JT refrigerator is determined
Design of capacitated networks with tree configurations
No full textThe authors wish to thank anonymous referees for their helpful comments.This paper considers the problem of designing a capacitated network with a tree configuration (CTP). For a given set of nodes with their capacities, k types of link facilities with various characteristics, acid installation cost for connecting each pair of nodes using each type of link facility, the problem is to find a tree network which satisfies the given traffic requirements between all pairs of nodes and minimizes total installation cost. We formulate (CTP) as an integer programming problem using path variables. To solve the linear programming relaxation which has exponentially many variables, we develop a polynomial-time column generation procedure. Moreover, to tighten the formulation, an efficient preprocessing procedure is devised and some classes of valid inequalities are found. Using the results, we develop a branch-and-cut algorithm with column generation where an efficient branching rule is adopted. Computational results show that the algorithm can solve practically-sized problems to optimality within a reasonable time
Development of a nonlinear near-wall turbulence model for turbulent flow and heat transfer
No full textA new nonlinear near-wall turbulence model is developed on the basis of realizability constraints to predict turbulent flow and heat transfer in strongly nonequilibrium flows. The linear k-epsilon-f(mu) model of Park and Sung (Fluid Dyn. Res., 20 (1997) 97) is extended to a nonlinear formulation. The stress-strain relationship is derived from the Cayley-Hamilton theorem in a homogeneous flow. The ratio of production to dissipation (P-k/epsilon) is employed to solve an algebraic equation of the strain dependent coefficients. A near-wall treatment is dealt with by reproducing the model coefficients from a modified strain variable. An improved explicit heat flux model is proposed with the aid of Cayley-Hamilton theorem, which includes the quadratic effects of flow deformations. The near-wall asymptotic behavior is incorporated by modifying the f(lambda) function. Emphasis is placed on the model performance on the, truncated strain terms. The model performance is shown to be generally satisfactory. (C) 2002 Elsevier Science Inc. All rights reserved
The archaeological, ethnographic, and physical landscape of California's Ahjumawi Lava Springs State Park trails
No full textAhjumawi Lava Springs State Park is a place of beauty and sacredness. The\ud
location of the park is part of traditional Pit River Ahjumawi land. Within the park\ud
many sites are recorded and these sites are connected by prehistoric and contemporary\ud
trails. Landscape theory introduces the idea that these sites and trails are part of the cultural\ud
landscape of the Ahjumawi. To assist in understanding the cultural landscape of\ud
the trails, both oral interview and archaeological data are used. By studying oral interview\ud
and archaeological data, it is possible to conclude that the trails function today as\ud
in the past as a way to connect spiritual/sacred and resource areas and information relating to the trails and is passed down from generation to generation.CSU, Chic
Understanding the interactions among local communities, protected areas and tourism: case studies of Kruger National Park and Purnululu National Park
No full textNew management approaches for protected areas emphasise a 'humans in nature' perspective, with protected areas seen as intrinsically connected with surrounding human populations. Tourism often provides a connection between these communities and protected areas. While both protected area managers and tourism operators can benefit from tourism, only recently has concern been directed towards its effects on local communities. This study investigated these effects.
A mixed methodology combining ethnographic approaches with social-ecological system perspectives was used to gain an in-depth understanding of the complex and changing environment in which protected area tourism operates. Interactions among protected areas, tourism and local communities were investigated using guidelines for resilience assessment. This approach focussed on identifying system states, drivers and issues, using these to develop indicators for monitoring. Methods included repeat semi-structured interviews, participant observation and document review. Two case studies provided focus: Kruger National Park, South Africa and the adjacent communities of Cork and Belfast, and Purnululu National Park, Australia and the nearby Indigenous community of Warmun.
The research revealed a complex, multi-faceted relationship between protected area tourism and local communities. Some economic benefits accrued to community members, although these were not widely distributed. Members expressed a desire for greater access to the Parks and the associated perceived benefits. In the Purnululu case study, this included resolution of and greater involvement in Park governance. In both studies, local communities had a contested relationship with the Parks‘ natural resources, with strong connections to nature and the Parks juxtaposed against perceptions of separation. Lack of skills, education and money impeded the accrual of benefits in both case studies.
The indicators derived focus on the interactions among local communities, the Parks and their tourism. Intrinsic socio-cultural values held by local communities for their protected areas and community involvement in and benefits from Park tourism are emphasised. These indicators provide a much-needed basis for engaging these communities in Park-based tourism and monitoring the success or otherwise of these efforts
