The authors examined factors related to participation in walking, gardening or yard work, and sports or exercise in 686 community-dwelling adults 60-95 years of age from Wave IV of the population-based Americans' Changing Lives Study. Logistic regression revealed that male gender, being married, and better functional health were associated with greater likelihood of participating in gardening o...

The 6-min walk test (6MWT) is a common component of fitness assessments of older adults; however, differing course configurations might affect 6MWT performance. It is unclear how comparable 2 different configurations are. To determine the comparability of 2 courses, 35 adults >65 years of age completed two 6MWT, once walking around a 20- by 5-yd outdoor rectangle and once on an indoor oval trac...

In a container terminal, containers unloaded from a ship are moved to the yard during the import operation. The export operation is the reverse of the import process. When a ship is served by multiple shore-cranes having both loading and unloading activities at the same time, a yard-machine can process an import container and an export container in one single round-trip. This paper investigates...

On October 15, we met to listen to a presentation by Marques Griffin from ChevronTexaco. He gave an overview of the entire oil production process and gave an idea of what types of positions his company had available. We also had this semester’s officer auction, where bidders could hire an officer for an hour to do such as things as cleaning or yard work. Our volleyball tournament to be held on ...

We present simulations, without electrodynamical assumptions, of Bsx, y, Hstdd, MsHstdd, and JcsHstdd in hard superconductors for a variety of twin-boundary pinning potential parameters, and for a range of values of the density and strength of the pinning sites. We numerically solve the overdamped equations of motion of up to 10 flux-gradient-driven vortices which can be temporarily trapped at ...

Large-lot exurban landscapes could incorporate ecological design in order to contribute ecosystem services. In our study, we use a survey of 126 Southeast Michigan homeowners to examine respondents’ stated preferences for residential yard images, and compare those with reported current use and management of their actual yards. We found that stated preferences are not necessarily related to actu...

This paper reports the findings of using multi-agent based simulation model to evaluate the sawmill yard operations within a large privately owned sawmill in Sweden, Bergkvist Insjön AB in the current case. Conventional working routines within sawmill yard threaten the overall efficiency and thereby limit the profit margin of sawmill. Deploying dynamic work routines within the sawmill yard is n...

In a modern rail–rail transshipment yard huge gantry cranes transship containers between different freight trains, so that hub-and-spoke railway systems are enabled. In this context, we consider the transshipment yard scheduling problem (TYSP) where trains have to be assigned to bundles, which jointly enter and leave the yard. The objective is to minimize split moves and revisits. Split moves a...
