The R gene coding for phage lambda lysozyme (lambda L), cloned under the control of the PL promoter on a multicopy vector, is expressed in an Escherichia coli strain auxotrophic for tryptophan. Induction by a thermal shift after tryptophan supplementation in a culture initially brought into stationary phase by tryptophan starvation leads to highly increased expression. A thermally unstable mutant protein, difficult to obtain under standard conditions, can be easily produced by post-stationary-phase expression. It is shown that this is due to a drastic decrease in the heat-shock-induced proteolysis normally observed on thermal induction. These data are discussed in relation to our present knowledge of stringent and heat-shock responses.

Thermal Induction

In previous work the authors have demonstrated that when hydrogen is combusted in stoichiometric proportions at 1 atm and 1200 K, and singlet oxygen comprises 0–20% of the oxidizer, an optimal range of exergetic efficiency exists. The maximum exergetic efficiency occurs at approximately 10%. Over this range, roughly 60% of the total exergy destruction occurs prior to ignition. This is a significant result because it suggests that the exergetic efficiency of combustion might be improved at a fundamental level by chemical means, thereby inherently increasing the efficiency of fuel use for a desired energy application. The objective of the study presented in this paper is to analyze the reaction mechanisms for combustion with varying percentages of singlet oxygen, to determine which reaction pathways most influence the observed trends in exergy destruction and exergetic efficiency. This was accomplished by performing both sensitivity and rate-of-production analyses of the hydrogen-oxygen combustion mechanism. The results of the analysis show that the presence of singlet oxygen governs the rate of production of hydroxyl and other key radicals. These key radicals directly affect the phenomenological processes associated with chemical induction and thermal induction during ignition. Therefore, the observed optimum exergetic efficiency correlates to the quantity of singlet oxygen in the inlet charge that minimizes exergy destruction by fostering chemical reactions due to radical formation to a greater extent than thermal heat release. The results of this analysis are noteworthy and provide new insight regarding how the exergetic efficiency of combustion may be optimized by introducing singlet oxygen, thereby altering the reaction pathways to enhance energy conversion in a fundamental way that could have important implications for improved fuel use.

Temu giring (Curcuma heyneana Val & Zijp) is a traditional medicinal plant that is believed in community as an analgesic. The objective of this research was to determine the analgesic activity of the C. heyneana rhizome by using infra red (IR) thermal induction method in mice. Mice were divided into 7 groups. Group 1 served as negative control, group 2,3,4,5 served as treatment groups which is  given ethanolic extract of C. heyneana rhizome at  dose of 5, 25, 125, and 625 mg/kg respectively, group 6 and 7 served as  comparable groups, given antalgin 65 mg/kg and morphine sulphate 1.3 mg/kg respectively. The observation have been done, included to pain resistance of mice which exposed by infra red (IR) every 10 minutes for 80 minutes. The data were analyzed by ANOVA at the significance level of 95%. Ethanolic extract of C. heyneana at the doses of 25, 125, and 625 mg/kg had significant effect to reduce the pain compared to the negative control (p<0.05). Ethanolic extract of C. heyneana rhizome at dose of 125 mg/kg, had the same effect to antalgin 65 mg/kg  (p≥0.05), while the ethanolic extract of C. heyneana at the dose of 625 mg/kg had the same effect as morphine sulfate 1.3 mg/kg (p≥0.05). It can be concluded that ethanolic extract of C. heyneana rhizome has analgesic activity.   Keywords: temu giring, analgesic, Curcuma heyneana, rhizome
