Abstract:

This paper deals with the mechanical properties of concrete with steel fibers subjected to temperatures up to 500°C. Now a day concrete are being used extensively in the construction that might be subjected to elevated temperatures. The behavior of concrete structures at elevated temperatures is of significant importance in predicting the safety of structures in response to certain accidents or particular service conditions. Concrete mixes of M 50 have been designed along with steel fibers from 0.5-4% by weight of cement. Specimens were made and subjected at room temperature, 100, 200,300,400

Abstract:

Rotating bending fatigue tests were carried out to investigate the effects of temperature on the fatigue strength and the fracture mechanism of an 18 % Ni maraging steel at room and elevated temperatures of 473K and 673K. Fatigue strength was higher at elevated temperatures than at room temperature, though static strength was decreased by softening at elevated temperature. There was no effect of temperature on crack morphology and fracture mechanism. On the other hand, during fatigue process at elevated temperature, the specimen was age-hardened and the specimen surface was oxide. That is, the

To assure adequate fire performance of concrete structures, appropriate knowledge of and models for performance of concrete at elevated temperatures are crucial yet currently lacking, prompting further research. This article first highlights the limitations of inconsistent thermal boundary conditions in conventional fire testing and of using constitutive models developed based on empirical data obtained through testing concrete under minimised temperature gradients in modelling of concrete structures with significant temperature gradients.

Abstract:

The determination of “ultra” fast fracture strengths of five silicon nitride ceramics at elevated temperatures has been made by using constant stress-rate (“dynamic fatigue”) testing with a series of “ultra” fast test rates. The test materials included four monolithic and one SiC whisker-reinforced composite silicon nitrides. Of the five test materials, four silicon nitrides exhibited the elevated-temperature strengths that approached their respective room-temperature strengths at an “ultra” fast test rate of 3.3 × 104 MPa/s. This implies that slow crack growth responsible for elevated-tempera

Abstract:

Elevated CO2 concentration (eCO2) generally increases plant growth by improving photosynthesis, but it is unclear whether eCO2 can alleviate the negative effects of elevated temperatures, especially in high-temperature years. Manipulative experiments with elevated [CO2] and temperature were conducted in North China to understand the effect of elevated CO2 concentration and temperature on wheat. The photosynthesis, An–PAR and A–Ci curve parameters, growth period, biomass, yield component, and yield of wheat were investigated under different [CO2] (around 400 and 600 ppm) and temperatures (ambie

With the exception of SHM, all drugs killed a greater proportion of cells at the higher temperature, as assessed by the colony-formation assay. Drug-dose enhancement ratios were 1.6, 2.8, 2, and 1:1 for BCNU, AZQ, cis-DDP, and SHM, respectively.

AbstractAlthough adhesives, particularly those based on epoxy resins, are finding increasing use in structural applications, their utilization at elevated temperature (>150°C) has been limited by their relatively poor thermal and thermo-oxidative stability.

Abstract:

High nighttime temperatures adversely affect rice grain yield and quality by causing early panicle emergence, decreased pollen germination, increased spikelet sterility, and chalkiness. The severity of these effects depends on genotype, growth stage, stress period, and temperature. High nighttime temperature leads to structural abnormalities in starch granules, modify the amounts of amylose and amylopectin, and disturb the expression pattern of genes involved in starch biosynthesis and accumulation, ultimately affecting the cooking properties of rice grains. To ensure sustainable rice producti

Abstract:

Purpose This work aims to present an experimental study of steel fibre-reinforced concrete (SFRC) subjected to high temperature, especially focusing on residual behaviour. Design/methodology/approach Compressive strength and split tensile strength of SFRC cubes and ultimate bending strength of prisms were evaluated under ambient and elevated temperatures. The specimens were heated by ceramic heaters and then repacked for testing. Findings The results showed that a compressive strength of SFRC is reduced by 38 and 66 per cent, tensile strength is reduced by 25 and 59 per cent and ultimate bendi

Abstract:

The pore and grain surface of reservoir rocks often has clay and other fine material attached onto pore walls. It has been long recognized that brine salinity and pH are key factors affecting the attractive forces between pore surfaces and fines. If mobilized particles are assembled in sufficient quantities, they obstruct pore throats and reduce the permeability of the formation. There is anecdotal evidence of substantial fines migration during steam injection enhanced oil recovery operations. As of yet, the mechanism of fines release with temperature is unexplained.

Abstract:

Short-term variations in temperature associated with climate change have been noted to affect the physiological processes and metabolite profile of plants, including the nutritional status, ultimately affecting their growth and development. An evaluation of the effects of elevated temperatures on the growth and nutritional quality of cowpea was performed during this experiment. The main objective was to evaluate the effects of short-term elevated temperatures on the nutritional quality of cowpea at different growth stages. Surface-sterilized seeds of cowpea (cv. Soronko) were germinated in pot

Abstract:

The development of bleaching of the youngest leaves of actively growing ivy geranium (Pelargonium peltatum) has been observed as the season progresses from late spring to summer. Cultivar differences in foliar bleaching in response to elevated air temperature were studied. Ivy geranium ‘Beach’ and ‘Butterfly’ were grown in media containing sphagnum peat and perlite (70:30 v/v) for 6 weeks in modified greenhouse chambers with air temperatures averaging 28/16 or 36/22 °C (day/night). ‘Beach’ had greater plant width, growth index, leaf area, total fresh weight, and total dry weight than ‘Butterfl
