Quadratic Optical Nonlinearity And Geometry Of 1:1 Electron Donor Acceptor Complexes In Solution
(2010-06-04)The knowledge of geometry of molecular complexes formed via molecular association in solution through weak interactions is always important to understand the origin of stability and function of an array of molecules, ... -
Qualitative similarities and differences between monkey and human visual perception
Animal models play a crucial role in helping neuroscientists unravel the computations supporting behaviour at the resolution of a single neuron in the brain. In vision science, the macaque monkey is the pre-eminent model ... -
Quality-quantity trade off during antibody production and the design of optimal passive immunization protocols
Passive immunization has been used classically to rapidly clear antigen and reduce disease burden. Surprisingly, recent studies have found passive immunization to induce lasting improvements in the humoral response, ... -
Quantification of Air-Sea CO2 exchange from the Southern Ocean during last deglaciation
Glacial and interglacial cycles are natural, rhythmic patterns of global climate. These cycles are primarily driven by variations in solar forcing, commonly known as Milankovitch cycles. The solar forcing includes eccentricity ... -
Quantification of Uncertainties in Urban Precipitation Extremes
(2018-05-25)Urbanisation alters the hydrologic response of a catchment, resulting in increased runoff rates and volumes, and loss of infiltration and base flow. Quantification of uncertainties is important in hydrologic designs of ... -
Quantitative Laser-Based Diagnostics and Modelling of Syngas-Air Counterflow Diffusion Flames
(2018-06-05)Syngas, a gaseous mixture of H2, CO and diluents such as N2, CO2, is a clean fuel generated via gasification of coal or biomass. Syngas produced via gasification typically has low calorific values due to very high dilution ... -
