The Impact

Cable tensile forces in winch-assist harvesting have been investigated in order to assess the safety concerns of the technology. However, the literature is lacking, particularly in regards to the impact of winch design. In this study, a Summit Winch Assist tethering a feller-director on ground slopes up to 77% was monitored for four days. The cable tensile forces were simultaneously recorded at the harvesting and anchor machine at a frequency of 100 Hz. Cameras and GNSS devices enabled a time study of the operations and the recording of machine positions. Winch functionality and design were disclosed by the manufacturer and used for the interpretation of the results. The cable tensile forces reached 296 kN at the harvesting machine and 260 kN at the anchor machine. The slow negotiation of obstacles while moving downhill recorded the highest peaks, mainly due to threshold settings of the winch in the brake system activation. Lower but significant peaks were also recorded during stationary work tasks. The peaks, however, were limited to a few events and never exceeded the endurance limit of the cable. Overall, the study confirmed recent findings in cable tensile force analysis of active winch-assist operations and provided evidence of the underlaying mechanisms that contribute to cable tensile forces.

This chapter analyses how Britons responded to the febrile political and social crises of the Americas in the 1860s. Although the American Civil War created a particular challenge – and great confusion – to observers in the United Kingdom, that conflict was one of a wider range of concerns in balancing the demands of rival imperial and new post-colonial powers to preserve British influence. Considering opinions expressed travel writing and political commentary, the chapter argues that Britons struggled to balance competing interests – in economic affairs, in geopolitical strategy, in imperial authority, and in suppression of the slave trade – to maintain a manifestly uncertain dominion over the Americas. Touching on British concerns stretching from the Mosquito Coast to the Pacific north--west, the chapter suggests that crises in the Americas illuminated diverse priorities and anxieties.

Management Recommendations

Abstract A questionnaire was sent to each Ranger District in the Pacific North-west Region of the USDA Forest Service to get information on present snag-management programs. Ninety-five percent of the responding Ranger Districts left snags at levels that ranged from 0.15 snags/ha (0 06/ac) to 12-15 snags/ha (5-6/ac) on all forested lands. Live trees were intentionally left as future snags on 93% of the Ranger Districts. Live trees were killed to create snags on 41% of the Ranger Districts. Management recommendations are made as to the kind of snags to leave and methods of maintaining them. West. J. Appl. For. 1:41-43, April 1986

In the present number of these Contributions, I resume the consideration of Captain Sir Edward Belcher’s magnetic observations, of which the first portion, viz. that of the stations on the north-west coast of America and adjacent islands, was discussed in No. II. The return to England of Her Majesty’s ship Sulphur by the route of the Pacific Ocean, and her detention for some months in the China Seas, have enabled Sir Edward Belcher to add magnetic determinations at thirty-two stations to those at the twenty-nine stations previously recorded. In the notice of the earlier observations, a provisional coefficient was employed in the formula for the temperature corrections of the results with the intensity needles, as no experiments had then been made for the determination of their individual co­efficients. As soon therefore as Sir Edward Belcher had completed the observation of the times of vibration of those needles at Woolwich, as the concluding station of the series made with them, Lieut. Riddell, R. A. undertook the determination of their several coefficients, which was performed in the manner and with the results described in the subjoined memorandum.

Gulf Of Nicoya

During a visit to Costa llica in the year 1910 I was able to spend about ten days in the comparatively little-known peninsula of Nicoya. The trend of the peninsula is north-west to south-east, and it is separated from the mainland by the Gulf of Nicoya, a shallow arm of the Pacific Ocean, which opens to the sea on the south-east.
