Advanced experimental measurements of heterogeneous strain and temperature change in metals
This work investigates elevated temperature deformation in the nickel-based superalloy Haynes 230 and elastocaloric cooling in shape memory alloys. Three loading conditions were examined in the elevated temperature portion: fatigue crack growth, creep, and tension. Measurements were made on varying …

A descriptive study of the relationship between preoperative body temperature and intraoperative core temperature change in adults under general anaesthesia
… Despite numerous guidelines on perioperative temperature management, perioperative hypothermia remains common. Prewarming to prevent redistribution hypothermia is supported by evidence, but not widely practiced. We investigate the measurement of preoperative mean body temperature as a …

Assessment and prediction of the potential threats of temperature change and invasive species to the sustainability of Northern Irish sea fisheries
… the way in which species interactions may change under the uncertain climatic future is imperative if the management of important resources is to be successful. Consumer – resource interactions underlie population dynamics and distribution, yet there is little known about how these …

Spatial estimation of future temperature changes over Africa
… since time immemorial. However, these long-term changes are very important because of some of the consequences to mankind. Because the changes are small ones in relation to daily experiences, many people find it difficult to perceive and accept these changes. This might cause doubts in the minds …

Internal and structural variability in global urban climate projections in CMIP6
Climate change is projected to impose substantial impacts and climate-driven threats to urban areas. Effective development decisions and local actions to manage these risks rely on robust climate projections that are specific to built landscapes. A robust modeling framework to address uncertainty …

A Warmer, Green Golden Rule
… goal of this paper is to analyse the impact of temperature changes on the green golden rule. The green golden rule is the maximization of consumer utility based on consumer preference between consumption and environmental stock. The trade-off between environmental stock and consumption which is …

Thermal buckling and postbuckling of symmetrically laminated composite plates
… are subjected to the conditions of a uniform temperature change and a linearly varying temperature change along the length of the plate. Postbuckling in the presence of a uniform temperature change and nonlinear response to imperfections in the form of a thermal gradient through the thickness …

Effects of rate and timing of short-lived climate forcer mitigation on cumulative warming and temperature targets
… and calculates radiative forcing and global mean temperature change. Impulse response functions were used to calculate the concentration of carbon dioxide in the atmosphere and the global mean temperature change. The resulting temperature change was used to evaluate the effects of SLCF mitigation …

Determining Heat Island Response to Varying Land Cover Changes Between 2004 and 2017 Within the City of Reno, Nevada
… was to investigate the role of land cover changes through time in influencing spatial variability of the surface urban heat island of the metropolitan area of Reno-Sparks, Nevada. Free and widely available thermal data from Landsat 7 ETM+ (Enhanced Thematic Mapper Plus) sensor was gathered …

Reciprocal Differences in F2 and F3 Nellore-Angus Halfblood Steers for Growth and Health Traits
… there was a negative correlation of rectal temperature change and ADG from d 0 to 14 post challenge. Rectal temperature change post BVDV challenge was positively correlated with ADG from weaning to yearling weight for NANA (r = 0.62, P = 0.002) and ANNA (r = 0.28, P = 0.026) steers. Only …

Non-invasive in vivo ultrasound temperature estimation
… dose in a variety of situations. The therapeutic temperature changes in target tissues range from few degrees for releasing chemotherapy drugs encapsulated in the thermosensitive liposomes to boiling temperatures in complete ablation of tumors via cell necrosis. High intensity focused ultrasound …

Potential of temporal and spatial analysis techniques as tools for exploring changes in forest site productivity and following environmental interactions : Finnish-German comparative study
… of this study is the detection of possible changes in forest site productivity and interaction with changes in the environmental conditions by the use of temporal and spatial analysis techniques. Height and radial increments of Norway spruce (Picea abies L. Karst) and Scots pine (Pinus …

Indirect measurement of the electrocaloric effect
… agree with the direct method (actually measuring temperature change with a thermometer). However, there was no obvious systematic error: sometimes the indirect temperature change was larger and sometimes smaller. The discrepancies were beyond the experimental errors. The majority of the present …

Influence of Bracket Type Combined with Delayed Light Activation on Bracket-Adhesive Shear Bond Strength
… with bracket manipulation on adhesive temperature change, shear bond strength (SBS), degree of conversion (DC), and adhesive remnant index (ARI) score when using a resin adhesive. Specimens from four bracket types: stainless steel with a mesh base (SSm), polycrystalline with a dovetail …

Organic Enrichment of Scottish Salmon Fish Farm Sediments: A Quantitative Analysis of Sulphur Biogeochemistry
… and oxygen demand. The effect of seasonal temperature change and increasing organic matter input on these properties was examined in detail during a short term period after an enrichment pulse. A high resolution data set was obtained using state-of-the-art micro electrodes. These …

Field monitoring of integral abutment bridge approach slabs
… precast approach slab were instrumented. Changes in concrete strain and temperature at distributed plan locations and at several locations through the slab thickness were measured. Global displacements of the slabs due to thermal deformations were also measured. Results indicate that slab …

Investigation of the Dimensional Stability in DSP Cement Paste
… paste behaves anomalouly in response to temperature change, i.e., the thermal expansion is followed by a time-dependent delayed contraction at isothermal condition. This characteristic was found to be related to the pore structure and the elastic properties of the paste. A …

Modelling aquifer thermal energy storage systems
… fluid cools as it passes through a heat exchanger at the surface before being injected into a second, colder reservoir. In the summer, the cold fluid is extracted to provide a source of cooling, absorbing heat rejected from buildings. The extracted cold fluid heats up and is injected into …

Effects of Temperature and Thyroid Hormone on Oxidative and Lipid Metabolism in Juvenile Lake Whitefish (Coregonus Clupeaformis)
… aspect of biological function is influenced by temperature, including metabolism. Factors such as seasonal change and climate change both contribute to environmental temperature variability. While many eurythermal fish species can acclimate to varying environmental conditions by adjusting …
