Morphometrics of the avian lung. 3. The structural design of the passerine lung
(1984)
The lungs of 46 adult, wild passerine birds belonging to 8 species have been analysed morphometrically, both by light and electron microscope. Volumes were estimated by point counting, surface areas by intersection counting, ...
Testing a von Liebig Crop Response Function against Polynomial Specifications
(1985)
Crop responses to fertilizers traditionally have been specified as polynomial functions. Recently, criticisms were raised against such specifications because they force substitution between nutrients and overestimate the ...
Morphometrics of the avian lung. 2. The wild mallard (Anas platyrhynchos) and graylag goose (Anser anser).
(1982)
The lungs of 5 wild mallard ducks (Anas platyrhynchos) and 5 feral graylag geese (Anser anser) of mean body weight 1.04 and 3.84 kg, respectively, were fixed in situ by intratracheal infusion of 2.3% glutaraldehyde, pH 7.4 ...
A scanning electron microscopic study of the air and blood capillaries of the lung of the domestic fowl (Gallus domesticus)
(Birkhäuser-Verlag, 1982)
Air and blood capillaries of the lung of the domestic fowl constitute the functional gas exchange units. They anastomose profusely and interlace with each other in 3 dimensions. Air capillaries are not blind-ending tubules ...
Gill structure of a fish from an alkaline lake: effect of short-term exposure to neutral conditions
(Research Press, 1995)
The morphology and morphometry of the gills of Oreochromis alcalicus grahami, a unique ureogenic teleost that lives in the alkaline environment of Lake Magadi, Kenya (pH 10, , temperature 30 – 40 °C) were examined by ...
Assessing The Ability Of Two Soil Types In The Removal And Retention Of N And P Nutrients From Fish Pond Effluents.
(University of Nairobi, 2004)
Effectiveness of two soil types found at Sagana, Kenya, black clay soil (eutric Vertisol) and a red clay soil (chromic Cambisol), in retaining nutrients from pond effluent was investigated. A laboratory experiment was ...
The effects of temperature on muscle pH, adenylate and phosphogen concentrations in Oreochromis alcalicus grahami, a fish adapted to an alkaline hot-spring
(Wiley, 1983)
The concentrations of phosphorylcreatine (PCr), adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), inorganic phosphate (Pi), pyruvate and lactate were determined in freeze-clamped ...
