We report specific heat and μSR measurements on Th and/or B substituted UBe13. The specific heat data show that either Th or B substitution reduces the Kondo temperature TK and increases the entropy at the superconducting transition by almost 20%, indicating an enhanced density of states. However, whereas μSR shows clear evidence for magnetic correlations for Th substitutions, no magnetism is observed for B substitutions. The enhanced specific heat jump in the B-substituted material is associated with a change in the (...) superconducting properties as TK is reduced. (shrink)

The purpose of this article is to comprehensively review studies that have examined the relation between diet and childhood obesity. The review specifically considers the roles of total energy intake and energy density; dietary composition; individual foods, food groups, and dietary patterns; beverage consumption; and eating behaviors. The paper also discusses methodological considerations and future research directions and concludes by summarizing the evidence presented and highlighting the ethical issues surrounding providing dietary advice.

An epistemic logic is built up on the basis of an analysis of two skeptical arguments. the method used is to first construct an inference relation appropriate to epistemic contexts and introduce "a knows that..." as an operator giving rise to sentences closed with respect to this new concept of inference. soundness and completeness proofs are provided using auxiliary three-valued valuations.

Using covariant derivatives and the operator definitions of quantum mechanics, gauge invariant Proca and Lehnert equations are derived and the Lorenz condition is eliminated in U(1) invariant electrodynamics. It is shown that the structure of the gauge invariant Lehnert equation is the same in an O(3) invariant theory of electrodynamics.

Childhood obesity is a serious problem for increasing numbers of children around the world. According to the International Obesity Task Force, 1 of 10 schoolaged children worldwide is overweight or obese, a number totaling 155 million; of these, 2-3% are obese. Prevalence is highest in the Americas and Europe, followed by the Near/Middle East, with smaller but growing numbers in the Asia-Pacific and Sub-Saharan regions of the world.In the United States, which provides the data for much of this report, prevalence (...) continues to rise. The most recent nationally representative data indicate that 33.6% of individuals aged 2-19 years were overweight and 17.1% were at risk for overweight in 2003-2004, compared to 28.2% and 13.9% in 1999-2000, respectively. In this age group, the prevalence of overweight or at risk for overweight was highest among Mexican Americans, followed by Non-Hispanic blacks and Non-Hispanic whites, and a higher percentage of males were overweight compared to females.

Structural change in the cellular prion protein, PrPC to a ProteinaseK‐resistant β‐sheet‐rich insoluble form PrPSC and its accumulation have been considered to be central to the pathogenesis of the prion diseases (TSE). In a recent paper, Deleault et al have shown that specific endogenous RNA molecules can induce in vitro structural conversion of endogenous PrPC to PrPSC.1 Small highly structured synthetic RNAs can also induce this conversion process.2 However, recent in vivo results show that PrPSC is not directly involved in (...) the prion pathogenesis.3 It is possible, however, that nucleic‐acid‐induced PrPSC associated with the inducer nucleic acid could be the components of the infectious agent.

A Principle of fundamental importance, if it is valid, for the interpretation of the Pentekontaetia is laid down by the authors of A. T.L. iii in its most rigorous terms: it is that Thucydides has set events ‘in proper order … without any deviation whatever’. The conclusion appears to the present writer to be founded ultimately on a false assumption about Thucydides' purpose in these chapters, namely that he set out to write an outline history of the period of fifty (...) years to which he refers in 118.2 and, in effect, in 97. An examination of these passages reveals that it is not the outline of a period as a period that is offered, but rather the account of a particular theme or process falling within the period: his purpose in presenting the theme there defined is to be seen from the setting of the excursus as a unit in Bk. I rather than from the statement in 97.2: the due significance of this last, and of the demarcation of a period in 118. 2, is to be seen only in this wider context. (shrink)
