Barnhart, Benjamin J. (Johns Hopkins University School of Hygiene and Public Health, Baltimore, Md.). Residual activity of thermally denatured transforming deoxyribonucleic acid from Haemophilus influenzae. J. Bacteriol. 89:1271-1279. 1965.-The level of residual transforming activity of heated deoxyribonucleic acid (DNA) (i.e., 1 to a few per cent of native DNA-transforming activity) was found ...

Spores heated in water at 54 C for up to 1 hr were plated on nutrient agar immediately or held for 3 days in aerated water at 23 C and then plated. Under these conditions, holding was optimal for recovery, increasing survival percentage up to 20-fold over values for immediate plating. Recovery was prevented partially or completely, however, when spores were held in any of the following solution...

Purpose: This study was performed to determine the effects of heated humidified anesthetic gases, via a heated and humidified circuit (HHC), on body temperature and shivering. Methods: A quasi-experimental design with pretest and posttest measures was used. Data was collected from 71 patients who underwent musculoskeletal surgery for clavicle or upper arm fractures under general anesthesia from...

This report has been prepared as a part of the Agreement on Research Participation and Technical Exchange under the International Code Application and Maintenance Program. KS-i Test 35-1 data on the behaviour of the heated rod temperatures in the partially uncovered VVER Core model were simulated with RELAP5/MOD3.2 to assess the code, especially its non equilibrium (unequal phase temperatures) ...

We analyze the asymptotic behavior of agents engaged in an infinite horizon partially observable stochastic game as formalized by the interactive POMDP framework. We show that when agents’ initial beliefs satisfy a truth compatibility condition, their behavior converges to a subjective ǫ-equilibrium in a finite time, and subjective equilibrium in the limit. This result is a generalization of a ...

Partially observable planning is one of the most general and useful models for dealing with complex problems. In recent years there have been significant progress on the development of planners for deterministic models that offer strong theoretical guarantees over certain subclasses of tasks. These guarantees however are difficult to establish as they often involve reasoning about features that...

Prospect of timely cleaning livestock complexes from accumulated manure prevents environmental pollution. For this purpose, the most promising was “cold” method dehelminthization a heap manure, complete neutralization chicken when heated and dried at temperatures above 100 °C, “dry” for neutralizing horse, pig, cow, sheep helminth eggs using Kranz biothermal method. humans animals, science has ...

1. Ribosomes isolated from the cortex tissue of goat brain contain very small amounts of spermidine and spermine. Ribosomes isolated from spermidinetreated slices have a higher spermidine content. 2. The polyamines partially prevent the temperature-dependent breakdown of ribosomes into acid-soluble nucleotides. 3. The 'melting' temperature of ribosomes rises slightly when the ribosomes are heat...
