The thermal dependent principal refractive indices of a new promising IR nonlinear optical crystal BaGa4Se7 at wavelengths of 0.546, 0.5806, 0.644, 0.7065, 1.530, 1.970, and 2.325μm were measured by using the vertical incidence method within the temperature range from 25 to 150 ◦C. We derived equations of thermal refractive index coefficients as a function of wavelength that could be used to ca...
The extinction spectra of laboratory generated sea salt aerosols have been measured from 1 µm to 20 µm using a Bruker 66v/S FTIR spectrometer. Concomitant measurements include temperature, pressure, relative humidity and the aerosol size distribution. The refractive indices of the sea salt have been determined using a simple har-5 monic oscillator band model (Thomas et al., 2004) for aerosol wi...
Shifting public imaginaries have played a vital role in shaping government and citizen responses to COVID-19 Aotearoa/New Zealand. During the nation’s first lockdown, general expressed support, at times even enthusiasm, for strict measures put place curb spread of virus. Less than year later, what had begun as nationalistic rallying cry ‘unite together’ ‘be kind’ while ‘combatting COVID-19’ too...
Infants make predictions about actions they observe already during the first year of life. To investigate the role of the motor system in predicting the end state of observed actions, 12-month-old infants were shown movies of ordinary and extraordinary object-directed actions. The stimuli displayed a female actor who picked up an everyday object (a cup or a phone) and brought it to either her m...
A high sensitivity refractive index sensor based on a single mode-small diameter no core fiber structure is proposed. In this structure, a small diameter no core fiber (SDNCF) used as a sensor probe, was fusion spliced to the end face of a traditional single mode fiber (SMF) and the end face of the SDNCF was coated with a thin film of gold to provide reflective light. The influence of SDNCF dia...
Thermodenuding particles can provide insights into aerosol composition and may be a way to create particles in laboratory chambers that better mimic the atmosphere. The relative volatility of secondary organic aerosol (SOA) was investigated by evaporating organics from the particles using a thermodenuder (TD) at temperatures between ∼ 60 and 100 C. Volatility was influenced by the parent hydroc...
