Computer-assisted forest road design mainly relies on a high-resolution digital elevation model (DEM) to provide terrain data for supporting the analysis of features. The resolution and accuracy DEM in representing structures varies depending preferred dataset which then reflects some essential features such as alignment, slope, earthwork. In this study, three sections were designed by using DE...

As a continuation of the authors’ research presented in previous years (ISARC), these authors focus on the processing aspect of the 3D terrain models acquired from heterogeneous 3D scan sources. This includes a revision of the authors’ ICP-based merging algorithm to achieve better accuracy in the ever-changing shape of an earthwork site with acceptable penalty in speed, and the introduction of ...

background: oral vanadyl sulfate (vanadium) induces normoglycemia, proliferates beta cells and prevents pancreatic islet atrophy in streptozotocin-induced diabetic rats. soteriological method is used to quantitate the proliferative effects of vanadium on beta-cell numbers and islet volumes of normal and diabetic rats. methods: adult male sprague-dawley rats were made diabetic with intravenous s...

Dust generated in earthwork construction activities can seriously affect the air quality at a site and have adverse effects on health of workers. To accurately quantitively analyze distribution characteristics dust effect prevention measures during under normal with control measures, multiple collection points one meteorological parameter point were placed site. From half an hour before to afte...

Abstract Research in 1970 vaulted Becán to prominence on the landscape of great Maya centers. Mapping, excavation, and ceramic stratigraphy revealed that its enigmatic earthwork, first recorded archaeologically 1934, was a fortification built at end Preclassic period. Large-scale warfare thus unexpectedly turned out have very deep roots lowlands. The site's wider implications remained obscure, ...
