The chronobiological effect on the pharmacokinetics of liposomal encapsulated ampicillin (LEA) was compared at noon (1200) and midnight (2400) after intravenous injection of 50 mg/kg of LEA in rats. The effects of fasting on the circadian rhythms of LEA were also investigated. Serial blood samples were collected for 2 h. Bile and urine were collected during the entire study. Plasma data was ana...

We investigate fluid transport in random velocity fields with unsteady drift. First, we propose to quantify fluid transport between flow regimes of different characteristic motion, by escape probability and mean residence time. We then develop numerical algorithms to solve for escape probability and mean residence time, which are described by backward Fokker-Planck type partial differential equ...

Recent scholarship has documented an alarming increase in the sex ratio at birth in parts of East Asia, South Asia and the South Caucuses. I argue that parents engage in sex selection because of patrilocal norms that dictate elderly coresidence between parents and sons. Sex ratios and coresidence rates are positively correlated when looking across countries, within countries across districts, a...

In 2005 four outstanding multiple burials were discovered near Eulau, Germany. The 4,600-year-old graves contained groups of adults and children buried facing each other. Skeletal and artifactual evidence and the simultaneous interment of the individuals suggest the supposed families fell victim to a violent event. In a multidisciplinary approach, archaeological, anthropological, geochemical (r...

[ABSTRACT What does it mean to empower people through the housing in which they live, and how is this empowerment to be achieved? These are the questions which are examined in this paper. Typologies of empowerment processes are devised in an attempt to make sense of the conceptual and empirical variety involved. The distinction between ‘top-down’ and ‘bottom-up’ empowerment orientations is argu...

A partial differential equation for the residence time moments is derived, as a generalization of the ...
