Response of Continuous Steel I-Girder Bridges Subject to Temperature Variation
Thermal deformation of the superstructure in continuous slab-on-girder bridges must be freely permitted to avoid potential adverse behavior due to the development of thermal forces. The use of fixed and guided bearings can introduce a significant amount of restraint against thermal deformation …

TEMPERATURE VARIATION IN MARQUETTE, MICHIGAN, CONCERNING SKELETAL MUSCLE DEGRADATION PATTERNS FOR POSTMORTEM INTERVAL DETERMINATION
… manner. This study examined the effect of temperature on the degradation patterns of vinculin, a skeletal protein, and the levels of essential metals in human skeletal muscle. Calcium concentrations were also observed for evidence of calpain activation, which degrades vinculin. Once …

The Combined Role of ENSO-driven Sea Surface Temperature Variation and Arctic Sea Ice Extent in Defining Climate Conditions in the Southwestern United States
… periods of increased precipitation and/or cooler temperatures in the American southwest during the Little Ice Age (LIA) were due to strong El Niño events; historical records also describe expanded Arctic SIC at this time. We use 16th-19th century Arctic SIC records from the ACSYS Historical Ice …

Application of liquid crystals to surface temperature measurement on plates heated by cyclic bending
Temperature is a parameter which is important because of its influence on other material properties. Many temperature measurement techniques are available but few of them permit a direct visualization of surface temperature Variation. The Liquid crystal method is one of the rare methods that …

An Integrated Time-Temperature Approach for Predicting Mechanical Properties of Quenched and Tempered Steels
… from the numerical integration of the time-temperature profiles of both the heating and cooling portions of the tempering cycle. The model provided a very good agreement between experimental and predicted hardness when secondary hardening did not occur. The developed tempering model was then …

Modeling and simulation of high pressure composite cylinders for hydrogen storage
… issues arising from the high gas pressure, temperature variation, fire attack, and fracture failures are the main concerns. The focus of this study is to develop a Finite Element (FE) model to predict the performance of composite cylinders subjected to extreme mechanical/thermal loadings and …

A temperature insensitive low noise RC relaxation oscillator
A 50 kHz temperature insensitive RC relaxation oscillator is presented. A novel RC branch, which has a zero temperature coefficient (ZTC) point in its charging curve, is used so that the period of the oscillator is insensitive to temperature variation. With the absence of current source in the RC …

Intact soil core experiments reveal that temperature and depth influence microbial community function and impact the fate of nitrogenous fertilizer amendments
… studied in ecological context of depth and temperature combined and we hypothesize that diurnal temperature variation, large in surface soils and more narrow at depth, will result in a differential response to N-input. To investigate both the fate of exogenous N-inputs and microbial …

Temperature measurement and thermal control of die casting processes using CCD cameras
A non-contact temperature measurement system for the die casting process is developed, using low-cost, charge-coupled device (CCD) cameras. Factors present in an industrial setting that affect non-contact temperature measurement are identified, and a system is developed to overcome these factors. A …
