roundabout methods of production
1987Methods of production are roundabout if they use produced means of production or the services of capital goods as well as those of land and labour, the latter being considered original or primary factors of production.

Accident Analysis & Prevention, 2017
May roundabouts be safer for cyclists than intersections? How are safe roundabouts designed? This paper tries to answer these questions on the basis of a before-after safety study of conversions of intersections to 255 single-lane roundabouts in Denmark. The before-after study accounts for long-term accident and injury trends and regression-to-the-mean

History of the Present, 2022
Abstract The Gilets jaunes brought attention to the existence and demands of the popular classes as other than the deplorables of the far right. This essay examines the ideas of an innovative group of historians who interpret the Gilets jaunes as evoking and enacting the unresolved issues of the revolutions of 1789, 1848, and 1871 on the

Modern Suburban Roundabouts in Croatia - Flower and Turbo roundabouts
Scientific journal of civil engineering, 2019Turboroundabouts are specially designed multilane roundabouts with spiral circulatory roadway and physically separated traffic lanes. This roundabout layout was developed in the late nineties of the last century with the aim of increasing the traffic safety and capacity at classic multi-lane roundabouts.

Modeling gridlock at roundabout
Computer Physics Communications, 2015We propose a cellular automaton model to study the traffic patterns at a roundabout. We obtain the complete phase diagram which consists of four distinct phases: free flow, congestion, bottleneck, and gridlock. For the six possible transitions among these four phases, we observe only five transitions.

Modelling roundabout capacities. [PDF]
, 2015 There has been extensive research and development into the capacity of modern offside priority roundabouts since the 1970’s. Despite this, there remains a major gap in existing knowledge with regards to the factors and variables which affect roundabout entry capacity.

STKE The Drosophila nervous system has been used as a model system for studying the molecular signals underlying the developmental choices of axons at the midline. Growth cones that display the receptor Roundabout (Robo) are repelled from crossing the midline, whereas those featuring the receptor Frazzled are attracted across the midline.

Die Volkskunde in der DDR der 1960er und 1970er Jahre hat sich - begleitet von einem letztlich produktiven Diskurs über das Fachverständnis - als einzigartiges Forschungsfeld etabliert und tiefgreifende Veränderungen erfahren. Die Einbettung in die akademische Landschaft der DDR, beeinflusst von der DDR- Wissenschaftspolitik, stand im Fokus.
