COMBINATORIAL ACTIVATION AND REPRESSION BY SEVEN TRANSCRIPTION FACTORS SPECIFY DROSOPHILA ODORANT RECEPTOR EXPRESSION.

Combinatorial activation and repression by seven transcription factors specify Drosophila odorant receptor expression.

The mechanism that specifies olfactory sensory neurons to express only one odorant receptor (OR) from a large repertoire is critical for odor discrimination but poorly understood.Here, we describe the first comprehensive analysis of OR expression regulation in Drosophila.A systematic, RNAi-mediated knock down of most of the predicted transcription

Permafrost-derived dissolved organic matter composition varies across permafrost end-members in the western Canadian Arctic

Organic matter, upon dissolution into the aqueous state as dissolved organic matter (DOM), can undergo mineralization by microbes.There has been increasing Camera effort to characterize DOM released from thawing permafrost because it may perpetuate a permafrost carbon feedback.Permafrost-derived DOM often has a composition that can be highly suscep

Lean thinking for a maintenance process

The maintenance process shares significant operating costs in an organisation.Lean thinking can be incorporated into maintenance activities through applying its principles and practices/tools.Lean maintenance (LM) is a prerequisite for lean manufacturing systems.This research proposes a new structure for LM process based on a systematic literature
