The Global Burden of Disease Study notes a substantial decrease in long-established global health threats such as communicable diseases and malnutrition, while underscoring the rise in non-communicable diseases and years lived with potentially disabling illnesses and injuries. One important but largely overlooked specialty where these two trends intersect is that of nutrition and disability. Ro...
Social interactions among animals raised in pens can aff ect their performance. In this study direct and competitive models were compared to investigate the infl uence of social genetic eff ects on variation of carcass weight (CW), carcass lean meat content (LM) and ham round shape (RS) in heavy pigs. Four sequential models including, in addition to sex and slaughter group fi xed eff ects, the ...
Recent numerical simulations of a disordered system [5] have shown the existence of two different relaxational processes (called stimulated and spontaneous) characterizing the relaxation observed in structural glasses. The existence of these two processes has been claimed to be at the roots of the intermittency phenomenon observed in recent experiments. Here we consider a generic system put in ...
The electron density and temperature profiles measured by the Thomson scattering diagnostic on the COMPASS tokamak are used for estimation of electron kinetic energy, energy confinement time, and effective charge number Z(eff). Data are compared with the line-integrated electron density measured by a microwave interferometer in an ohmically heated plasma with a circular cross section. An error ...
Limitations on Transmutation Performance Due to Reactivity Constraints in Accelerator Driven Systems
An analysis is presented to characterise the reactivity effects in molten lead energy amplifiers. Limitations in the nominal k-eff value to avoid reaching criticality in abnormal conditions impose restrictions to the nominal value of the neutron flux. If those restrictions become very severe because of safety features, the transmutation performance would not be good enough. Very long burnup per...
The thermodynamic properties of loop quantum cosmology (LQC) without considering the Lorentz term were established in \cite{Zhu09}. In this paper, we extend result to recent proposed new model LQC with term. We investigate thermodynamics on apparent horizon Friedmann-Lematre-Robertson-Walker universe. shows that effective density and pressure modified Friedmann equation not only determines evol...
Tumor infiltration with effector CD8(+) T cells (T(eff)) predicts longer recurrence-free survival in many types of human cancer, illustrating the broad significance of T(eff) for effective immunosurveillance. Colorectal tumors with reduced accumulation of T(eff) express low levels of T(eff)-attracting chemokines such as CXCL10/IP10 and CCL5/RANTES. In this study, we investigated the feasibility...
during the last years, the concept of input congestion and technical ineff-ciency in data envelopment analysis (dea), have been investigated by manyresearchers. the motivation of this paper is to present models which obtain thedecreased output value due to input congestion and technical ineciency. more-over, we extend the models to estimate input congestion, technical ineciencyand output red...
The Phenomenologically Emergent Dark Energy model, a dark energy model with the same number of free parameters as flat $\Lambda$CDM, has been proposed working example minimal which can avoid current cosmological tensions. A straightforward question is whether or not inclusion massive neutrinos and extra relativistic species may spoil such an appealing phenomenological alternative. We present bo...
