Nature, 2010 New functional materials can in principle be created using colloids that self-assemble into a desired structure by means of a programmable recognition and binding scheme. This idea has been explored by attaching 'programmed' DNA strands to nanometre- and micrometre- sized particles and then using DNA hybridization to direct the placement of the ...

Best Practices: To Lock or Not to Lock Patients'Rooms: The Key to Autonomy?
Psychiatric Services, 2008Many patients with schizophrenia experience prominent negative symptoms. Functional impairment often results in patients who remain in their rooms for most of the day. It has thus become common practice in many psychiatric wards to lock patients' rooms during much of the morning and afternoon hours to encourage participation in ward activities and ...

This case demonstrates two uncommon conditions presenting in a single patient. A 47-year-old male with a history since childhood of generalised tonic clonic seizures, well controlled, not on anti epileptic medication for 6 years presented with frequent complex partial seizures, disorientation and deteriorating short term memory. EEG was normal however,

Three-Dimensional Lock and Key Colloids [PDF]
Journal of the American Chemical Society, 2014 Colloids with well-defined multicavities are synthesized through the hydrolytic removal of silica cluster templates from organo-silica hybrid patchy particles. The geometry of the cavities stems from the originally assembled cluster templates, displaying well-defined three-dimensional symmetries, ranging from spherical, linear, triangular, tetrahedral,

Locks, keys and symbioses [PDF]
Nature, 2003 The association between legumes and nitrogen-fixing bacteria requires molecular recognition to allow bacterial entry into root hairs. The discovery of a novel type of plant receptor clarifies how this happens.

A simple lock contains a bolt and one or more levers which are lifted the correct amount by the appropriate key, thus allowing the bolt to be moved in and out. In addition there are often circular obstructions or “wards” to stop some keys being turned in the lock.

Lock and key model system [PDF]
EPL (Europhysics Letters), 2008 The lock and key concept is important for various biological and colloidal self-assembly processes. We study the basic and common underlying mechanisms within a model system which consists of a biaxial elliptical key immersed in a hard-sphere solvent and a smooth lock substrate into which the key can fit geometrically.

Keys for Locks in Administrative Argument
Administration & Society, 1994Developments in public administration are better understood as rhetorical rather than scientific in Herbert Simon's meaning. Administrative arguments succeed by using the six keys to acceptance of classical rhetoric: symmetry, metaphor, ambiguity, private interest presented as public good, selective use of information, and suspension of disbelief To ...
