With low temperature long time (LTLT) cooking it can take hours for meat to reach a final core temperature above 53°C and germination followed by growth of Clostridium perfringens is a concern. Available and new growth data in meats including 154 lag times (tlag), 224 maximum specific growth rates (μmax) and 25 maximum population densities (Nmax) were used to developed a model to predict growth...

We use a self–consistent modeling of X-ray cluster properties to constrain cosmological scenarios of structure formation in the case of open cosmological models. We first show that an unbiased open model can reproduce present day observations, provided that the density parameter is in the range 0.15−0.4. Although this estimate is derived in a rather different way, it is very close to dynamical ...

To the Editor: I read with great interest the article by Tsukamoto and Ohara who reported the temporal worsening of sleep-disordered breathing (SDB) in patients with acute coronary syndrome (ACS).1 The authors stated that SDB in the acute phase of myocardial infarction (MI) has not been well analyzed before and that there are no previous reports documenting changes in the severity of SDB during...

Thirty-eight lactating dairy cows including 6 ruminally cannulated cows were used in a feeding study to assess effects of feed sources that differed in dietary nonfiber carbohydrate (NFC) composition and ruminal degradability of dietary protein (RDP) on production, ruminal, and plasma measures. The design was a partially balanced, incomplete Latin square with three 21-d periods and a 3 x 2 fact...

We investigate observational constraints on the cosmic equation of state from measurements of angular size for a large sample of milliarcsecond compact radio-sources. The results are based on a flat Friedmann-Robertson-Walker (FRW) type models driven by non-relativistic matter plus a smooth dark energy component parametrized by its equation of state p x = ωρ x (−1 ≤ ω < 0). The allowed interval...

Complexes between the Py(2)N(6)Ac(4) (H(4)L) ligand containing four carboxylate pendant arms and trivalent lanthanide ions have been synthesized, and structural studies have been made both in the solid state and aqueous solution. The crystal structures of the La, Ce, Sm, Tb, Dy, Ho, Er, Tm, and Lu complexes, with chemical formulas [LaH(2)L](NO(3)).3H(2)O (1), [Ce(4)L(2)](NO(3))(4).30H(2)O (2), ...

It has previously been argued that the repressor of protein synthesis initiation factor 4E, 4E-BP1, is a direct in vivo target of p42mapk. However, the immunosuppressant rapamycin blocks serum-induced 4E-BP1 phosphorylation and, in parallel, p70s6k activation, with no apparent effect on p42mapk activation. Consistent with this finding, the kinetics of serum-induced 4E-BP1 phosphorylation closel...

It has been shown previously that administration of chlorpromazine to rats leads to a decrease in total serum tryptophan and total amino acids, but an increase in that fraction of tryptophan freely diffusible rather than bound to serum albumin (Bender, 1975~). At the same time, there are changes in brain tryptophan uptake and 5-hydroxytryptamine synthesis, supporting the view that serum diffusi...

The cold dark matter (CDM) scenario for structure formation in the Universe is very attractive and has many successes; however, when its spectrum of density perturbations is normalized to the COBE anisotropy measurement the level of inhomogeneity predicted on small scales is too large. This can be remedied by a tau neutrino of mass 1MeV − 10MeV and lifetime 0.1 sec − 100 sec whose decay product...
