In my paper “On the Effect of Temperature on the Specific Inductive Capacity of a Dielectric” (‘Phil. Trans.,’ A, 1890), the values obtained for the temperature-variation of specific inductive capacity of four of the liquid dielectrics investigated were compared with the corresponding values of the temperature-variation of refractive index found by Messrs. Dale and Gladstone.

This study aimed to investigate the use of water hyacinth to produce liquid smoke. The study observes the temperature and time variables of yield, pH, density, and refractive index in the production of liquid smoke from water hyacinth. The sequence of the work is as follows: first, water hyacinth was cut into 5 cm sections and then sun-dried for 2–3 d, depending on the weather. Next, 550 g of dried water hyacinth was added to the pyrolysis reactor. The temperature variations were 200°C, 400°C, and 600°C, and the time variations were 1, 4, and 7 h. As a result, liquid smoke was produced with varying yield, pH, densities, and refractive indices. The best results in this research are liquid smoke pyrolysis at a temperature of 400°C and 4 h with the acquisition of a yield of 93 mL, pH 2–4, a density of 1.080,8 gr/mL, and a refractive index of 1.339,6, with chemical component 41.45% total acid, 2.44% phenol and 56.10% carbonyl.

Abstract It is well established that temperature variability affects a range of outcomes relevant to human welfare, including health (Gasparrini et al., 2017) emotion and mood (Baylis et al., 2018), and productivity across a number of economic sectors (Carleton & Hsiang, 2016; Dell et al., 2014). However, a critical and still unresolved empirical question is whether temperature variation has a long-lasting effect on economic productivity and, therefore, whether damages compound over time in response to long-lived changes in temperature expected with climate change. Several studies have identified a relationship between temperature and GDP (Burke et al., 2015; Dell et al., 2012; Kalkuhl & Wenz, 2020), but empirical evidence as to the persistence of these effects is still weak. This paper presents a novel approach to isolate the persistent component of temperature effects on output using lower frequency temperature variation. Using three different datasets we find that longer temperature anomalies affect GDP growth as much or more than short-lived anomalies, implying persistent and therefore cumulative effects of climate change on economic output. The population-weighted global effect of -0.8 pp per degree is sufficient to reduce per-capita income in 2100 by 44% under RCP6, approximately an order of magnitude larger than damages currently represented in cost-benefit integrated assessment models (Diaz & Moore, 2017).

The effect of temperature variation on Fourier transform infrared (FT-IR) spectrometer response stability is investigated for wavenumbers from 10,000 to 100 cm−1 with the use of a temperature measurement and data acquisition system on the spectrometer optical bench. Spectrometer response instability is correlated with local temperature variation for two FT-IR spectrometer systems, with the use of various infrared source, beamsplitter, and detector combinations. The data obtained show that detector responsivity variation and beamsplitter misalignment associated with thermal instability of the spectrometer optical bench are responsible for the observed response instability. Response variation of up to 4% per °C temperature variation is observed. Variations of the laboratory environment and spectrometer purge gas supply temperatures are shown to affect spectrometer thermal stability directly.
