  • The conservation of artefacts and buildings has a long history, but the positive emergence of conservation as a profession can be said to date from the foundation of the International Institute for the Conservation of Museum Objects (IIC) in 1950 (the last two words of the title being later changed to Historic and Artistic Works) and the appearance soon after in 1952 of its journal Studies in Conservation.

  • An extended range of new sensing applications and solutions have emerged in different fields such as rural and forest fire detection [1], monitoring of industrial manufacturing processes [2], transport/logistics [3], and for personal services in areas such as healthcare and Ambient Assisted Living (AAL) [4]. These new advanced applications based on a new generation of sensing and communication capabilities are a consequence of the continuous advances in sensor technologies and wireless communication protocols that allow for greater autonomy of sensor nodes.

  • While Nesjar created the sculpture on the green in front of The Art Museum, he conducted a unique, outdoor seminar. The process involved building wooden forms to establish the basic shapes of the columnar pedestal and then a similar structure for the head itself. After completion of the wooden form, a mixture of crushed stone (imported from Norway) and iron tie-rods was packed within, and liquid concrete was injected under pressure from the base up. Nesjar later sandblasted the outer skin to expose the colorful aggregate.

  • Those of us involved in the healthcare of women have seen a remarkable transformation in screening techniques for cervical cancer and its precursors since the mid 1990s.  The staid old Pap smear technique of scraping cells from the cervix with a wooden spatula and cotton-tipped applicator and smearing them onto a glass slide is a thing of the past in most practices. We now use plastic collection devices to transfer cells from the cervix into a preservative which is sent to the lab for liquidbased cytology and reflex human papillomavirus (HPV) testing.

  • This review discusses various interactions between organic compounds, brought into the lead–acid battery via the separator, and their subsequent effect on battery performance. Historically, the interrelationship started with certain ‘expander’ actions on the lead morphology due to lignins, which leached out of the wooden separators of that time. Synthetic separator materials did not show this effect, but gained acceptance as they were far more stable in the hostile battery environment.

  • Stand your four buildings in place on the base following our floor plan. Before you stick them down, mark out where you would like to have the windows and doors. Windows would have been rectangular in shape with wooden frames and light green or blue glass. Doors were made from wooden boards, with two supporting planks added horizontally for extra strength. Draw or paint the windows and doors on the walls using a black pen to add detail. Now your buildings are ready, stick them to the main base.

  • Continuing improvements led to the furnace and bellows and provided the ability to smelt and forge native metals (naturally occurring in relatively pure form).[38] Gold, copper, silver, and lead, were such early metals. The advantages of copper tools over stone, bone, and wooden tools were quickly apparent to early humans, and native copper was probably used from near the beginning of Neolithic times (about 8000 BC).[39] Native copper does not naturally occur in large amounts, but copper ores are quite common and some of them produce metal easily when burned in wood or charcoal fires.

  • The lack of emphasis (about 10 % of the course) in connection design within a course is by no means a reflection of the significance of connections to the integrity of a structure. Instead, it is due to the time constraint in a semester and the common belief in the past that connections are standardized details that should be left to the fabricators. However, the connections are the glue that holds a structure together. Historically, connection failures have contributed to many structural failures, for example, the Hartford Civic Center in 1977 [1], the Hyatt Regency Hotel in...

  • Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems. It is a far-reaching term that may include simple tools, such as a crowbar or wooden spoon, or more complex machines, such as a space station or particle accelerator. Tools and machines need not be material; virtual technology, such as computer software and business methods, fall under this definition of technology.
