TL;DR: An anatomical study of the seed coat and hairs has revealed that this ancient Nubian cotton is similar, in the characters examined, to Gossypium arboreum Var.
Abstract: During an excavation at Afyeh, Egyptian Nubia, in 1962, the Archaeological Survey of India recovered some plant remains. These contained, in addition to charred cereals, a few cotton seeds and dung of small animals. An anatomical study of the seed coat and hairs has revealed that this ancient Nubian cotton is similar, in the characters examined, to Gossypium arboreum var. soudanense and G. herbaceum var. africanum. Some hairs recovered from the dung indicate that the animals were fed with this cotton. The significance of this find is that the Nubians did not know at that time the potentiality of cotton hairs for making textile, but they apparently recognized the nutritive value of cotton seeds for animal feed. The hairs show an early stage of evolution from the wild to the cultivated cotton, having convolutions in the middle and no convolution towards the ends.

TL;DR: In this article, reaction cross-sections for some forty-five cases in the range 167≥A≥6 are measured by the activation technique at (14.8±0.5) MeV neutron energy.
Abstract: (n, p) reaction cross-sections for some forty-five cases in the range 167≥A≥6 are measured by the activation technique at (14.8±0.5) MeV neutron energy. Measured cross-sections are compared with the cross-sections semi-empirically predicted by Gardner and Levkovskii. Experimental cross-sections are also compared with cross-section values obtained theoretically using a shell-dependent level density.

Abstract: The present study includes five new and three known species of trematodes from marine fishes of India. Records of new hosts and new localities are given. The new species are: Plagioporus longicaudus, Opegaster paramacrorchis, Pseudopecoelina elongata, Pseudopecoeloides scomberi and Hamacreadium leiognathi. The known species are: Podocotyloides parupenei (Manter, 1963) Pritchard, 1966, Hamacreadium mutabile Linton, 1910 and H. krusadaiensis Gupta, 1956. Hamacreadium leiperi Gupta, 1956 is considered a synonym of H. mutabile.The author wishes to express his gratefulness to Dr Ather H. Siddiqi for his guidance and to Professor H. W. Manter of the University of Nebraska, U.S.A. for his valuable comments. The present study was financially supported by the Council of Scientific and Industrial Research, New Delhi.

Abstract: Seasonal fluctuations in gross and net primary production values were quite apparent in surface waters and showed a bimodal type of distribution. The values were generally high during post winter months (March to May) and low during winter (February) and monsoon months (July and August). At different depths the rate of primary production was always found decreasing from surface to bottom. The rate of photosynthesis was found to be highly variable from time to time and at different depths.

TL;DR: It has been concluded that chromosomal sterility and cryptic structural hybridity play an important role in intersterility and the genetic distinctiveness of Indian tetraploid S. nigrum and S. nodiflorum.
Abstract: Morphological and cytological characters of Indian tetraploid S. nigrum (n=24) and S. nodiflorum (n=12) have been studied. The lack of close genetic relationship between the two species is shown by cytological studies of their triploid hybrids (n=18) which are sterile. It has been concluded that chromosomal sterility and cryptic structural hybridity play an important role in intersterility and the genetic distinctiveness of Indian tetraploid S. nigrum and S. nodiflorum,.
