Alcohol consumption and cycling in contrast to driving

Accident Analysis & Prevention, 2017
In Germany, the legal blood alcohol limit for cyclists is much higher (0.16 percent) than the limit for drivers (0.05 percent) - as long as no crash has occurred. The proportion of police-recorded crashes with personal damage under the influence is higher for cyclists than drivers, and the blood alcohol concentrations are higher for cyclists than ...

How Proteolysis Drives the Cell Cycle

Science, 1996
Oscillations in the activity of cyclin-dependent kinases (CDKs) promote progression through the eukaryotic cell cycle. This review examines how proteolysis regulates CDK activity—by degrading CDK activators or inhibitors—and also how proteolysis may directly trigger the transition from metaphase to anaphase.

Using Large Driving Record Samples and a Stochastic Approach for Real-World Driving Cycle Construction: Winnipeg Driving Cycle

Transportation Science, 2014
The challenges in the development of plug-in electric vehicle (PEV) powertrains are efficient energy management and optimum energy storage, for which the role of driving cycles that represent driver behaviour is instrumental. Discrepancies between standard driving cycles and real driving behaviour stem from insufficient data collection, inaccurate ...

Investigation of Motorcycle Emissions Tested by European Standard Driving Cycle and Bangkok Driving Cycle

SAE Technical Paper Series, 2013
<div class="section abstract"><div class="htmlview paragraph">Registered vehicles in Thailand, are currently required to pass the European standard (EURO3) driving cycle. Motorcycles comprise the registered vehicles in Thailand, thus it is important to study the exhaust emissions of motorcycles tested with both the European standard driving

What Drives Glacial Cycles?

Scientific American, 1990
The Milankovitch theory advocates that the glacial cycles have three components: the tilt of the earth's spin axis; the shape of the earth's orbit; and the interaction between the tilt and the eccentricity effects. These three factors work together to vary the amount of sunshine reaching the high northern latitudes in summer and allow the great ice ...

MEIOTIC DRIVE AND SEX CHROMOSOME CYCLING

Evolution, 2004
Sex-linked meiotic drive is found in a broad variety of taxa, including insects, birds, and mammals. In populations of some species, we see four types of sex chromosomes segregating: normal and driving X chromosomes and susceptible and resistant Y chromosomes.

Drive cycle development for tricycles

Clean Technologies and Environmental Policy, 2006
The absence of protocols through which an alternative technology for two stroke tricycles could be evaluated makes it difficult to compare these technologies and determine the best alternative. This study demonstrates the process of the development of a dynamometer test cycle that would be reflective of the actual driving conditions in Metro Manila ...

Development of Driving Cycles for Galle

2018 Moratuwa Engineering Research Conference (MERCon), 2018
Driving cycle construction has become more popular around the world to estimate pollution emission and traffic analysis. This paper presents the traffic based analysis related to performance of B128 and B130 route in Galle, Sri Lanka using basic traffic engineering parameters such as travel time, average and maximum speed, average acceleration and ...
