Design and Lab Implementation of an Air Source Transcritical CO2 Heat Pump
… (GWP) refrigerants for cold climate applications. A custom climate chamber was also constructed to simulate winter weather conditions typical of the northeastern United States. Both the TCHP and the chamber were fully instrumented to collect temperature, pressure, and mass …

Determination and control of some pollutants in indoor environments
… from building materials as studied both in a climate chamber and in a room with dampness-related floor emissions. The cTrap cloth was found to be efficient in reducing emissions of VOCs, stopping mycotoxins, and improving the perceived IAQ in a damp school building. The device was proved to be …

Improving the Fanger model's thermal comfort predictions for naturally ventilated spaces
… temperature needs to be correlated to an outdoor climate variable, thereby accounting for the psychological adaptations of occupants of naturally ventilated buildings that were largely ignored in the original climate chamber derivation of this parameter. A modified comfort mean skin temperature, …

Thermo and drought tolerance markers and regulation of heat stress proteins for chickpea (Cicer arietinum L.; Fabaceae) production in NE South Africa
… drought whereas after priming Acc#7 is better acclimated to drought than Acc#8 associated with osmotic adjustment on leaf relative water content (RWC) and higher capacity to protect photosynthetic activity, making Acc#7 potentially ideal for areas associated with intermittent drought spells. This …

Finite element model of a tennis ball impact with a racket
… against experimental data, obtained inside a climate chamber. Following validation of the ball model, an FE model of a head-clamped racket was produced and validated against experimental data. The validation included a range of inbound velocities, angles and spin rates, for impacts at a number …

Insects as a Sustainable Food Ingredient – Utilization of Carrot Pomace, Identification of Early Adopters, and Evaluation of Mealworm Acceptability
… were grown under controlled conditions in a climate chamber until they began to pupate, and statistical models were fitted to predict mealworm mortality, weight, days to pupation, protein content, fat content, and moisture content. An algorithm in Design Expert was used to optimize mealworm …

Towards a coupled δ18O sugar and δ2H n-alkane approach in paleoclimate research
… are increasingly used in paleohydrological and -climate reconstructions. However, previous studies found it challenging to disentangle the effects of past changes in δ18O and δ2H of precipitation (δ18Oprec and δ2Hprec, respectively) and changes due to evapotranspirative enrichment of leaf water. …

Concentrating human urine by evaporation
… at different temperature conditions in a climate chamber to determine the extent of urea hydrolysis . These experiments were evaporated for 95 hours. Urea hydrolysis experiments were repeated at 40°C and 70°C. However, these experiments were stopped once 100% of the water was removed from …
