Developing capacity in field epidemiology in England

Perspectives in Public Health, 2014
Epidemiology is the study of the distribution and determinants of healthrelated states or events (including disease). Public health professionals apply epidemiological methods to:* Assess the health states and health needs of specific populations;* design and implement interventions designed to improve the health of that population; and* evaluate the ...

Heat capacity of in a magnetic field

Physica B: Condensed Matter, 2000
Abstract Heat capacity measurements down to 0.5 K in a magnetic field up to 12 T have been performed on a single-crystal sample of a spin-ladder-like compound Cu 2 ( C 5 H 12 N 2 ) 2 Cl 4 . The singlet ground state with an energy gap becomes magnetic and gapless between 7 T ( H c1 ) and 13 T (

Field Capacity in Laboratory Columns

Soil Science Society of America Journal, 1953
Abstract It is shown that the material decrease in downward movement observed as soils approach field capacity cannot be explained in terms of capillary conductivity alone. Instead, the combined effects of decreasing capillary conductivity in the drying zone, hysteresis and reduced hydraulic gradients at all levels are involved.

Influence of Electric Field on the Capacity of Phospholipid Membranes

Nature, 1966
VARIOUS bimolecular models of the cell membrane have already been made1–3. Such bimolecular films separating two aqueous solutions are formed by applying a solution of phospholipids to the hole in a ‘Teflon’ cup.

Peak Capacity in Field-Flow Fractionation

Separation Science and Technology, 1981
Abstract Field-flow fractionation (FFF) peak capacity values have been computed with only two major assumptions: first, the plate height is supposed the sum of only two contributions, axial molecular diffusion and transversal nonequilibrium, and second, the steric effect has been neglected in the equations of retention and peak broadening.

Heat capacity of Gd0.06Er0.94Al2 in magnetic fields

Journal of Applied Physics, 1988
We have measured the specific heat of an arc-melted specimen of Gd0.06Er0.94Al2 in applied magnetic fields of 1, 3, 5, and 8 T from 4.5 to 40 K, and in zero field from 1.4 to 98 K. Inspection of entropy versus temperature with the lattice included shows that the maximum adiabatic cooling is 13 K and occurs from 30 K at 8 T to 17 K at zero field.

A Field's Capacity to support a Butterfly Population

Nature, 1964
THE controversy among ecologists on ‘density dependence’ swelled out of all proportion due to differences among authors in the meaning and use of such words as ‘carrying capacity’, ‘competition’ and ‘density’. Beneath these unimportant disagreements, however, there lies at least one fundamental question which has seldom been investigated: Does an area ...

Regenerative Capacity of Field Bindweed Roots

Weed Science, 1976
Lateral roots of a clone of field bindweed (Convolvulus arvensis L.) were dug each month for 12 months, cut into 6-cm long sections and grown in the dark on moist paper at 23 C to determine if regeneration varies seasonally. New shoots and roots were measured after 8, 11, and 14 days. After 14 days, 69% to 98% of the sections had produced shoots.
