TL;DR: In this paper, aggregate emission and absorption spectra have been studied in fluorescein, eosin and erythrosin in glycerol water frozen glass, and exciton splitting is also calculated using exciton model for non-crystalline aggregates.

TL;DR: The normal blood glucose level of Channa punctatus undergoes a seasonal change, but a post-spawning hyperglycemia is found during August, September, October and November and does not appear to affect the blood glucose in this fish.
Abstract: The normal blood glucose level of Channa punctatus undergoes a seasonal change. A post-spawning hyperglycemia is found during August, September, October and November. Fish kept out of water show increase in blood glucose level upto 24 hours. When returned to water, the asphyxial hyperglycemia subsides after 24 hours. Starvation does not appear to affect the blood glucose in this fish.

TL;DR: In this paper, the problem of torsional oscillations set up in an elastic stratum, one face of which is rigidly secured, by a rigid circular disk which is attached to the free surface of the material and which performs simple harmonic oscillations about its axis is solved after reducing it to the solution of a Fredholm Integral Equation of the second kind.
Abstract: This paper is concerned with straightforward solution of the problem of torsional oscillations set up in an elastic stratum, one face of which is rigidly secured, by a rigid circular disk which is attached to the free surface of the material and which performs simple harmonic oscillations about its axis. The problem has been solved after reducing it to the solution of a Fredholm Integral Equation of the second kind.

TL;DR: First leaves of 8-day-old seedlings of a field-resistant wheat showed a greater frequency of primary infections in subsidiary cells of stomata than those in a susceptible wheat.
Abstract: Seedlings can be used to predict field resistance, if any, of wheat varieties and experimental lines to wheat powdery mildew fungus,Erysiphe graminis f. sp.tritici. First leaves of 8-day-old seedlings of a field-resistant wheat showed a greater frequency of primary infections in subsidiary cells of stomata than those in a susceptible wheat. This method of predicting field resistance of experimental lines from seedling studies should prove time-saving because crosses involving field-resistant experimental lines can be made in the same generation.

TL;DR: The phylogenetic significances of the presence of diverse nature of karyotypes, participation of unequal bivalents in units of secondary association and also the occurrence of both consistent and inconsistent numbers of chromosomes in members of the family have been discussed.
Abstract: In the present investigation, the chromosome numbers for Lindenbergia indica (n=15 and 2n=30) and Mazus japonicus (n=20 and 2n=40) have been reported. The karyotype analysis revealed the presence of 4 and 8 satellited chromosomes respectively in their somatic complements. The two taxa under consideration show marked difference between them as regard the morphology of somatic chromosomes. On the basis of length, these chromosomes fall under 2 broad classes in both taxa but in L. indica they are either short or very short (9 morphological types) while in M. japonicus they are either long or medium-sized (12 morphological types).In general, the meiotic cycle is normal except showing a few cases of minor anomalies. In addition, multivalent formation takes place in M. japonicus. Secondary association of bivalents could be encountered in both taxa. In L. indica, as in some other genera under the family, the maximum association is in four groups indicating the basic number for the family. The presence of some extra-nuclear bodies in the pollen mother cells could be noted. These take bright stain with crystal violet but are Feulgen-negative.The karyotypes of four species worked out by the present authors, have been analysed. Moreover, the range of size variation in somatic chromosomes within the family have been compared and taxa possessing chromosome numbers in multiples of 5 (gametic) or 10 (somatic) have been enlisted. The phylogenetic significances of the presence of diverse nature of karyotypes, participation of unequal bivalents in units of secondary association and also the occurrence of both consistent and inconsistent numbers of chromosomes in members of the family have been discussed.

TL;DR: The morphology of the visceral arterial system of two teleostean fishes has been described and the coeliaco-mesenteric artery supplies to whole of the digestive system and associated glands, air-bladder mesentery and reproductive organs.
Abstract: 1. The morphology of the visceral arterial system of two teleostean fishes has been described. 2. InClarias batrachus the dorsal aorta is formed by the union of one pair of epibranchial arteries and supplies to the kidney, segmental muscles and body wall. 3. The coeliaco mesenteric artery supplies to the digestive tract and associated glands, air-bladder, pectoral girdles and mesentery. The posterior mesenteric artery also supplies to kidneys and reproductive organs. 4. InTor tor the dorsal aorta is formed by the union of two pairs of epibranchial arteries and supplies to the pectoral girdles, kidneys, segmental muscles and body wall. 5. The coeliaco-mesenteric artery supplies to whole of the digestive system and associated glands, air-bladder mesentery and reproductive organs.
