    Notes: The long-term safe withdrawal rate for a coastal aquifer in Mannar Island of Sri Lanka was assessed through the simulation of interface movement. A range of estimates of natural recharge sequence was first obtained from a water balance study considering the variations of factors affecting the soil moisture balance. The representative recharge sequence was then determined through the simulation of a field observed interface profile along a selected section. Following this, the sustainability of continuous water withdrawal in the future was assessed by limiting the extent of salt-water upconing. An increase in the withdrawal rate in the future would be possible through proper monitoring of the system response.

    Notes: The genetics of resistance to three Indian pathotypes of Xanthomonas campestris pv. oryzae, namely, IX01, IX08 and IX09, was studied in a landrace of Indica rice ‘ARC 10464’. Resistance to each of the two pathotypes IX01 and IX09 was governed by two independently-inherited dominant genes while a single dominant gene was operative against patho-type 1X08. The joint segregation tests conducted on F2 plant progenies (F3 families) using pathotypes IX01, IX08 and IX09 suggested that the gene/(s) effective against each of the pathotypes are different.

    Notes: Abstract CALFIRE, the acronym for CALculate Fire In Room and Enclosure, is a knowledge-based mathematical formulation of analytical and numerical procedures to predict the consequences of a fire in a room or enclosure. CALFIRE is a well-knit and integrated computer model that offers menu items such as heat release rate (HRR), flame height, vent size, and room temperatures of closed rooms, and rooms with natural and forced ventilation. Warnings and checks have been provided to prevent the misuse of the model. Care has been taken to require minimal keyboard responses in order to make CALFIRE a truly user-friendly, interactive fire model.

    Notes: Abstract The thermophilic fungus Malbranchea sulfurea produces extracellular α-amylase whereas α-glucosidase is mainly cell bound. Extraction of the cell bound enzyme was maximum with one molar NaCl, followed by Triton ×100 and Urea-Na2SO3 extractants. Supplementation of Triton ×100 in growth medium significantly affected the presence of enzymes at various locations. A role for cell bound α-amylase and α-glucosidase has been suggested in rapid starch utilization by the fungus during early growth phase.

    Description / Table of Contents: Zusammenfassung In dieser Untersuchung wird eine exakte Analyse der Ausbreitung eines passiven Kontaminierungsstoffes in einer zähen Flüssigkeit gegeben, die, befördert durch einen gleichförmigen Druckgradienten, in einem Parallelplattenkanal strömt. Der Kanal rotiert mit gleichförmiger Winkelgeschwindigkeit um eine zu seinen Wänden senkrechte Achse, wodurch sich eine Sekundärströmung ausbildet. Unter Verwendung eines generalisierten, für alle Zeiten gültigen Dispersionsmodells werden die longitudinalen DispersionskoeffizientenK i (i=1, 2, ...) als Funktionen der Zeit ermittelt. Es wird gezeigt, daßK 1=0 gilt und dieK 3,K 4, ... gegenüberK 2 schnell abnehmen.K 2 nimmt ab, wenn α, der dimensionslose Rotationsparameter, bis etwa zum Wert 2,2 ansteigt. Danach wächstK 2 mit α bis auf einem Endwert an, der etwa ab α=500 erreicht wird. Dieses anomale Verhalten vonK 2 findet eine physikalische Erklärung.
    Notes: Abstract The paper presents an exact analysis of the dispersion of a passive contaminant in a viscous fluid flowing in a parallel plate channel driven by a uniform pressure gradient. The channel rotates about an axis perpendicular to its walls with a uniform angular velocity resulting in a secondary flow. Using a generalized dispersion model which is valid for all time, we evaluate the longitudinal dispersion coefficientsK i (i=1, 2, ...) as functions of time. It is shown thatK 1=0 andK 3,K 4, ... decay rapidly in comparison withK 2. ButK 2 decreases with increasing α (the dimensionless rotation parameter) for values of α upto approximately α=2.2. ThereafterK 2 increases with further increase in α and its value gets saturated for large values of α (say, 500) and does not change any further with increase in α. A physical explanation of this anomalous behaviour ofK 2 is given.

    Notes: Abstract A new trematode, collected in 1971 from Ratnagiri, India, is described as Follicovitellosum indicum sp. nov. A new subfamily, Follicovitellotrematinae is created within the family Zoogonidae Odhner, 1911, to receive the new genus Follicovitellosum, with its genotype F. indicum. The new species is characterized by the follicularized nature of its ovary; the ovarian follicles are posttesticular. The vitellarium is further divided into several follicles which are largely in the pre-ovarian zone, but post-acetabular and posttesticular in location.

    Notes: Abstract A new digenetic trematode, collected 1969–1970 at Ratnagiri (India) from the marine eel Leptocephalus conger, is described as Indostomachicola kinnei n. g., n. sp. The new genus differs from Stomachicola Yamaguti, 1934 and Allostomachicola Yamaguti, 1958 in many characteristics. The new species is characterized by an unlobed ovary, absence of receptaculum seminis, and presence of post-acetabular seminal vesicle and a ventral pit.
