Where V is the instantaneous cylinder volume and is the polytrophic
If the accumulator is loaded or unloaded rapidly, the thermodynamic process of the gas state change belongs to an adiabatic process and the value of the polytrophic
exponent is n = 1.4.
head exponent is defined as:
They are nonlinear ordinary differential equations which describe the equilibrium density distribution in self-gravitating sphere of polytrophic
isothermal gas and have a singularity at the origin .
Cyanobacteria associations in shallow polytrophic
lakes: influence of environmental factors.
Other LMC Hymenoptera may live relatively longer lives, are synovigenic, the adults have polytrophic
ovaries and feed on sugary substances, as well as internal fluids (haemolymph) of their hosts, e.g., Nasonia vitripennis (Walker); (Werren 1980, Simbolotti et al.
Females typically have three spermathecae and polytrophic
ovarioles (Dodson 1978; Fritz & Turner 2002); ovaries may contain more than one flush of mature eggs at a time.
Phosphorus balance of a polytrophic
shallow lake with the consideration of phosphorus release.
Because crawfish are polytrophic
and consume significant quantities of invertebrates and seeds as well as detritus (Momot 1995), all water birds feeding in crawfish ponds compete with the crawfish for food.
On the broad nutritional requirements of the mud snail, Ilyanassa (Nassarius) obsoleta (Say), and its polytrophic
role in the food web.
