Temperature gradient chamber for relative growth rate analysis of yeast.
Relative growth is often used as a phenotypic measure to distinguish mutant and wild-type yeast or bacterial strains. Differential growth as a function of temperature is a convenient and accurate means of analyzing differences between strains. Slight differences in the genotypes of two strains frequently result in differential growth of the two strains as a function of temperature. We have deve...
متن کاملCharacteristic Points of Stress-Strain Curve at High Temperature
Determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. In this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. The critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. In a...
متن کاملStrain rate sensitivity of nanocrystalline Au films at room temperature
The effect of strain rate on the inelastic properties of nanocrystalline Au films was quantified with 0.85 and 1.76 lm free-standing microscale tension specimens tested over eight decades of strain rate, between 6 10 6 and 20 s . The elastic modulus was independent of the strain rate, 66 ± 4.5 GPa, but the inelastic mechanical response was clearly rate sensitive. The yield strength and the ulti...
متن کاملEarlier hatching time predisposes Cobb broiler chickens to tibial dyschondroplasia.
Fertile eggs from Cobb 500 broiler breeder hens were incubated to provide low starting egg shell temperatures (EST; 36.9°C to 37.3°C) which were gradually increased to 37.8°C during the first 7 to 15 days of incubation compared with eggs incubated with a constant EST of 37.8°C (standard conditions) over the first 18 days of incubation. Time of individual chick hatching (measured at 6 h interval...
متن کاملRelative effectiveness of herbal methionine compared to DLmethionine on growth, performance and carcass responses basis in broiler chickens
BACKGROUND: The degree to which the amount of aningested nutrient is absorbed and available to the body is calledbioavailability. OBJECTIVES: Relative effectiveness of herbalmethionine (H-Met®) compared to DL-methionine (DL-Met)was investigated in this experiment. METHODS: Exponentialregression analysis was used to determine bioefficacy of H-Met®based on body weight gain, feed intake and feed c...
