A dynamic coefficient of friction (COF) measurement device is described for use in recording shoe/floor slip resistance. This device is computercontrolled and allows changes in the shoe/floor interface velocity and vertical force applied during a test. Different sole materials, floors, and contaminants such as water or oil are testable. Repeatability tests of the device were conducted of four v...

Drowning is one of the most frequent causes of accidental or suicidal death, and more rarely it is associated with a homicide. Cases of drowning in water or in the sea are common. The authors report an unusual and peculiar case of drowning, that of a woman who accidentally fell inside a collection tank of waste oil of motor vehicles.

Author of such works as The Foundations of Modern Political Thought (1978) and Visions of Politics (2002) he served as the Regius Professor of History at the University of Cambridge, and currently as t...

An envelope echo signal measurement is proposed in this paper using echo signal observation from the 200 kHz echo sounder receiver. The envelope signal without any object is compared with the envelope signal of the sphere. Two diameter size steel ball (3.1 cm & 2.2 cm) and two diameter size air filled stainless steel ball (4.8 cm & 7.4 cm) used in this experiment. The target was positioned abou...

Microwave imaging techniques are prone to signal corruption from unwanted multipath signals. Near-field systems are especially vulnerable because signals can scatter and reflect from structural objects within or on the boundary of the imaging zone. These issues are further exacerbated when surface waves are generated with the potential of propagating along the transmitting and receiving antenna...

The establishment of a new oil terminal near Kulevi on the Black Sea coast of Georgia has become a highly controversial mega-project, and this article explores its political and environmental significance in the context of rising global demand for the region's oil and gas reserves. The Kulevi Terminal is intended to be a storage facility and a transfer point for black oil, fuel oil and other oi...
