Brewing has a long history in this country—first making an appearance in 1620 with the landing of the Pilgrims at Plymouth Rock in Massachusetts. Today, beers can be easily categorized into one of two types: 1) industrial, and 2) craft. The focus of this paper is on this second type, the "craft beer" and the so-called "renaissance" it experienced during the 1980s. In 1983, there were only 43 op...

The shocks and impacts encountered on small high-speed craft exceed the limits set for safe working practice according to current standards. European legislation regarding the exposure to vibration will have far reaching effects on the operators of such craft with respect to the safety of their employees. This paper sets out to highlight the vibration dose values that can be expected during typ...

abstract: background and aim:  micro-ultrasonic tips are similar to hand instruments in their clinical application of subgingival scaling.  in spite of their favorable results, excessive penetration of mini-insert ultrasonic scalers to the bottom of gingival pocket may cause harmful effects. the aim of this study was to evaluate the immediate effect of root instrumentation with gracey curettes ...

ACADIA 2007 The distinction between matter (mechanics) and information (electronics) in the context of responsive building skins has promoted unique design protocols for integrating sensor technologies into material components. Such a distinction results in applications of remote sensing after the process of material fabrication. Sensors are commonly perceived as electronic patches which initia...

[1] High‐speed video images of eight branches of a lightning stepped leader recorded at a frame rate of 300 kiloframes per second (kfps) (3.33 ms exposure) are analyzed, representing the fastest published frame rate measurements of stepped leader stepping by about 1 order of magnitude and the first observations of space stems/leaders associated with stepped leaders. Sixteen occurrences of space...

Numerous stepped spillways were built to date, namely on RCC gravity dams or on valley flanks besides embankment or rockfill dams, while some others are currently under design or construction. In some cases, slope changes may be required on stepped chutes, due to the topography, leading to reduced excavation and related economic benefits. A quite limited number of stepped spillways have been bu...

Traditionally, programming languages have been designed with an eye toward implementation on general-purpose computers. The advent of computationally-enhanced craft items–small programmable objects with simple geometries and scaled-down computational components–suggests the need for new language and software environment models tailored for these objects. In some respects, the task of the craft-...

BACKGROUND There is limited guidance on the design of stepped wedge cluster randomised trials. Current methodological literature focuses mainly on trials with cross-sectional data collection at discrete times, yet many recent stepped wedge trials do not follow this design. In this article, we present a typology to characterise the full range of stepped wedge designs, and offer guidance on sever...
