This paper explores the application of archaeological site formation theory to stranded wooden vessels and the scattered wreck-sites they produce. Shallow water wrecks and wreckage sites in the Au Sable Shores region of western Lake Huron are used to develop a preliminary classification of the processes operating on the breakup and deposition of wooden vessels. 2002 The Nautical Archaeology Soc...
Woodc:n poles are popular structural elements currently used by Manitoba Hydro for distribution lines and transmission towers. In recent years, a considerable number of such poles have failed duc to heavy build-up of ice on the lines. These failures may be attributed to the accuracy or reliability of the design methods and/or to the lack of adequate experimental information to evaluate the crit...
Wooden sticks used to suspend feces obtained for surveillance cultures were found to be the source of Rhizopus microsporus var. rhizopodiformis causing a pseudo-outbreak among 17 immunocompromised patients cared for in three different wards. Nonsterile wooden products should therefore not be used for collecting, handling, and processing specimens for microbiological examination.
Background and aims: Workplaces with poor lighting conditions often created occupational accidents or illness. This occurs because light cause visual and nonvisual effects on numerous physiological variables, such as the human sleep-wake cycle and cognitive performance. Indoor lighting conditions, as one aspect of the work environment, Influence on occupant’s mood, well-being, task performance ...
The Marashian government (Marashieh) had a Shia religion, they ruled from 760 to 906 AH in the Tabaristan region (now it is Mazandaran). During this period, the construction of mausoleums, shrines and elders of the Marashi government flourished. Unlike modern metal tombs most of them have wooden artifacts same as are in cenotaph mausoleum. These cenotaph mausoleums often have decorations with i...
The inherent control flexibility implied by solid-state lighting – united with the rich details offered by sensor networks – prompts us to rethink lighting control. In this research, we propose several techniques for measuring work surface illuminance and ambient light using a sensor network. The primary goal of this research is to measure work surface illuminance without distraction to the use...
Background and aims:The aim of the good quality lighting is that which balanced the needs of humans, economic and environmental issues, and created suitable lighting for a particular visual activity (e.g. reading, writing, etc.). Quality lighting is very important to incising productivity and learning of students. The main idea of energy-efficient lighting is to reduce the amount of electricity...

Dhow (LanJ) is a wooden vessel which is traditionally operating in Persian Gulf and Oman Sea. In contrast of its frequent lost, ordinary people believe that it has very good behavior at waves. In this study, by means of seakeeping computer software, authors have calculated its dynamic behavior in waves. Comparison between dhow performances in waves against seakeeping criteria has been made. The...
