Tornadoes: Mechanism and Control
Science, 1967If electrical energy is invoked to account for the high velocity of tornadoes, hydrodynamics restricts the possible mechanisms of energy exchange. In particular, the vortex is driven by a line sink of electrically heated air that must extend at least 5 kilometers high.

The mechanism and control of cytokinesis
Current Opinion in Cell Biology, 1997Cytokinesis is under active investigation in each of the dominant experimental model systems. During 1996 and 1997, several developments necessitated the reassessment of the prevailing model for cytokinesis. In addition, the inventory of proteins required for cytokinesis has grown considerably.

European Journal of Cancer (1965), 1970
Abstract Control mechanisms for cell movement and replication which have been detected in tissue culture and which seem to depend on mutual contact of the cells are discussed. Contact inhibition of movement amongst fibroblasts seems to depend on a contractile response that inhibits locomotion; but some inhibitions may depend on inadequate adhesion ...

Autoregulatory Mechanisms Controlling the Microprocessor
2010The Microprocessor, comprising the ribonuclease Drosha and its essential cofactor, the double-stranded RNA-binding protein, DGCR8, is essential for the first step of the miRNA biogenesis pathway. It specifically cleaves double-stranded RNA within stem-loop structures of primary miRNA transcripts (pri-miRNAs) to generate precursor (pre-miRNA ...

Army reform was recognised as much-needed in the aftermath of the Crimean War. D. A. Milyutin, Minister of War between 1861 and 1881, wrote this report in 1862 but it was twelve years before his proposals for universal military service were implemented in the reform of 1874.

Brain mechanisms in motor control
Life Sciences, 1974Publisher Summary This chapter describes the brain mechanisms in motor control. In primates, a zone of cerebral cortex lying anterior to the central fissure contains a set of neurons whose axons pass without interruption to the spinal cord through a nerve bundle named the pyramidal tract and the neurons of this tract are called pyramidal tract ...

This chapter discusses the way in which the Ba’thist regime monitored and enforced boundaries on acceptable interpretations of religion in Iraq. The Ba’thists built on and expanded the instructions that it had developed during the first decade of Saddam Hussein’s presidency. The work of local committees became more thorough and systematic.
