Multiple Functions of Malpighian Tubules in Insects: A Review
Insects, 2022 The Malpighian Tubules (MTs) are the main excretory organs in most insects. They play a key role in the production of primary urine and osmoregulation, selectively reabsorbing water, ions, and solutes.

Foaming Volume and Foam Stability. [PDF]
The Journal of Physical Chemistry, 1946 A method of measuring foaming volume is described and investigated to establish the critical factors in its operation. Data on foaming volumes and foam stabilities are given for a series of hydrocarbons and for a range of concentrations of aqueous ethylene-glycol solutions.

Indiana University Mathematics Journal, 2011 Klein foams are analogues of Riemann and Klein surfaces with one-dimensional singularities. We prove that the field of dianalytic functions on a Klein foam $ $ coincides with the field of dianalytic functions on a Klein surface $K_ $. We construct the moduli space of Klein foams and we prove that the set of classes of topologically equivalent Klein ...

Water absorption and salt attack resistance of coal ash brick made of different percentage of foam content [PDF]
, 2014 Coal ash which constitute of fly ash and bottom ash were proved to be used as main component in brick production. However, published work on the coal ash brick with addition of foam in order to produce lightweight brick is still lacking. This thesis
