    Notes: A low oxygen atmosphere, which shows promise of controlling insect infestations during storage of raisins was studied in relation to its effect on flavor changes during storage of raisins at 18.5 and 27°C for 1 yr. Raisins stored in the low oxygen atmosphere for 1 yr at 18.5 or 27°C were equal or superior in flavor quality and acceptability to similar samples stored in normal atmosphere for the same length of time.

    Notes: Abstract We propose a set of standards to aid the physician in the care of older patients. These standards are based on the practical experiences of our own group and of others with years of clinical practice in geriatric medicine. The standards also reflect the guidelines, position papers, and deliberations of various organizations concerned with the care of older people. This article does not discuss specific illnesses or the common geriatric syndromes. The proposed standards cover comprehensive care and assessment, especially of vulnerable elders and prevention of disease and disability. We also propose standards for facilitation of care across the health service continuum, care of the nursing home resident, and palliative and hospice care.

    Notes: A low oxygen atmosphere, known to control insect infestations in stored almonds, was studied to determine its effect on flavor changes in stored inshell almonds and almond meats at 18.5 and 27°C. Sensory comparisons of the products stored in low oxygen and normal atmosphere at these temperatures after 1, 3, 6, 9 and 12 months of storage indicate the following: (1) In normal atmosphere at both 18.5 and 27°C, inshell almonds were much more stable than almond meats; (2) In the low oxygen atmosphere, no significant differences were observed between storage as meats or inshell; (3) Temperature had a highly significant effect on off-flavor development in meats stored in normal atmosphere but no significant effect on those stored in the low oxygen atmosphere; (4) Storage in the low oxygen atmosphere caused less off-flavor development than in normal atmosphere for both meats and inshell almonds.

    Notes: Summary Depletion of high-energy phosphates, accumulation of inorganic phosphate and intracellular acidosis have each been proposed as important events in the transition from reversible to irreversible ischemic injury. To assess whether each variable is predictive of functional recovery on reperfusion, these were measured in the isolated isovolumic rat heart using31P NMR. Perfused hearts were subjected to either 10, 12 or 40 min of normothermic ischemia followed by 40 min of reperfusion. Hearts were then freeze-clamped for further analysis of phosphate metabolites by NMR and ion chromatography. High-energy phosphates, Pi, phosphomonoesters and pH were measured by31P NMR spectroscopy at 2 minute intervals. Heart rate and developed pressure were monitored simultaneously. All hearts undergoing 10 min of ischemia and 40% of hearts subjected to 12 min of ischemia demonstrated good functional recovery. The remainder of hearts ischemic for 12 min went into contracture on reperfusion with little return of function. Hearts subject to 40 min of ischemia went into ischemic contracture and showed no recovery on reperfusion. Intracellular pH, [ATP], and [Pi] measured prior to reperfusion did not predict the extent of recovery. However, phosphomonoesters were detected prior to reperfusion in all hearts that did not recover well, but were not observed in hearts that showed good mechanical recovery. Analysis of tissue extracts by31P NMR and ion chromatography indicated that the most prominent components of the phosphomonoesters were glucose 6-phosphate, α-glycerol phosphate and AMP. In conclusion, of the various phosphorus metabolites that can be measured by31P NMR, only one group, the phosphomonoesters, was predictive of functional recovery.

    Notes: Abstract In this paper, a new variable-metric method based on a rational, rather than a quadratic, model is proposed. A switching algorithm is also introduced which selects either the standard quadratic model or the new rational model, depending on which has the smallest condition number. Several functions are used to test the new method, and it is concluded that it is as efficient as the standard model in general and is superior for problems of high dimensionality. Considerable improvement is also obtained for high-dimensional problems when the switching algorithm is used.

    Notes: Abstract A conjugate-gradient method for unconstrained optimization, which is based on a nonquadratic model, is proposed. The technique has the same properties as the Fletcher-Reeves algorithm when applied to a quadratic function. It is shown to be efficient when tried on general functions of different dimensionality.

    Notes: Abstract A new generalized Polak-Ribière conjugate gradient algorithm is proposed for unconstrained optimization, and its numerical and theoretical properties are discussed. The new method is, in fact, a particular type of two-dimensional Newton method and is based on a finite-difference approximation to the product of a Hessian and a vector.

    Notes: Abstract We describe global optimization problems from three different fields representing many-body potentials in physical chemistry, optimal control of a chemical reactor, and fitting a statistical model to empirical data. Historical background for each of the problems as well as the practical significance of the first two are given. The problems are solved by using eight recently developed stochastic global optimization algorithms representing controlled random search (4 algorithms), simulated annealing (2 algorithms), and clustering (2 algorithms). The results are discussed, and the importance of global optimization in each respective field is focused.

    Notes: Abstract In this paper, low-order Newton methods are proposed that make use of previously obtained second-derivative information by suitable preconditioning. When applied to a particular 2-dimensional Newton method (the LS method), it is shown that a member of the Broyden family of quasi-Newton methods is obtained. Algorithms based on this preconditioned LS model are tested against some variations of the BFGS method and shown to be much superior in terms of number of iterations and function evaluations, but not so effective in terms of number of gradient evaluations.
