Abstract

During the course of clay investigation near Kalidhang, District Sirmur, Himachal Pradesh, some well preserved plant leaves were found in the varve type clays and a sample of it was also analysed for pollen studies. This note records interesting pollens of Pinus roxburghie. Gramineae, Oleaceae Quercus etc., including an abnorma13-winged pollen of Pinus and a large sized Gramineae pollen.

Abstract

A illustrated account of the pollen grains of 32 species of genus Clematis (Dill, ex) Linn., mostly Indian, has been presented and their systematic significance evaluated. The pollen is usually 3-zono-colpate, but some have 4-zono-colpate pollen as well. In C. cadmia Buch.- Ham. Ex Hk.f. & Thom., the pollen is panporate. The pollen features in Clematis exhibit a predominantly negatively reticulate sexine pattern and are of little phylogenetic significance.

Abstract

Pollen analysis of a sediment core from Priyadarshini Lake (Core S3), East Antarctica, has revealed the climatic oscillations in the region since Holocene. Three pollen zones have been identified on the basis of recovered pollen taxa and varying frequencies. Between 10,000 and 9,000 yr BP, cold and dry climate prevailed in the region as reflected by the dominance of grasses, Acritarch and very low frequencies of Cosmarium - a fresh water alga. The lake was probably shallow and smaller in dimension during this period. Between 9,000 to 2,400 yr BP, relative increase in grasses is witnessed though in fluctuating frequencies. Cosmarium also exhibits a distinct increasing trend, whereas Acritarch declines considerably. This overall change in the assemblage reflects the onset of warm and moist climate and the lake had a wider expansion during this phase on account of amelioration in climate than witnessed before. Between 2,400 and 1,000 yr BP, relatively reduced frequencies of grasses, coupled with total disappearance of Cosmarium, demonstrate that the climate changed once again to cold and dry. However, 1,000 yr BP onwards, marked increase in grasses coupled with exceedingly high values of Cosmarium implies that the climate ultimately turned warm and moist.

Abstract

Actinomycetes strains isolated from rhizosphere of two important medicinal plants Melissa officinalis and Heracleum candicans were evaluated for production of biological and proteolytic activities by selecting different media. In present investigations two strains Act-M-3 and Act-M-5 of Melissa officinalis produced maximum growth on Glucose ammonium salts (GAS) and Glycerol peptone beef (GPB) broths while strain Act-M-8 preferred GPB. Antibacterial and antifungal activities were registered more on GAS, GPB in addition to Nutrient broth (NB) against Bacillus subtilis, Alternaria and Pythium sp. by two strains Act-M-3 and Act-M-8 in comparison to Act-M-5. Proteolytic production was registered highest in Starch Broth (SB) by Act-M-3 than other two strains. However, Act-H-2 strain isolated from H. candicans recorded maximum growth on GPB while Act-H-5 and Act-H-6 obtained higher production on SB. GAS broth supported greater antibacterial activity by Act-H-2 and Act-H-6 strain towards E. coli and B. subtilis but less or weak effect was obtained by Act-H-5 strain in all the media tested. Antifungal effect against Pythium and Phytopthora sp. was found superior in GPB, GP, GAS and SB. Though proteolytic activity produced by Act-H-2 and Act-H-6 was more on SB, NB and GAS media. Strain Act-H-5 on other hand could not show any proteolytic production on GAS, GPB and SB.

Abstract

The current research was conducted to study the relation between happiness and psychological well-being among the parents of autistic children. This study explains the difference between level of happiness and psychological well being in autistic children and parents of non autistic children. To conduct this study, descriptive method was used. For collection of data purposive sampling technique was used. The sample size was 120 parents which included 60 parents of autistic children and 60 parents of non autistic children. The result showed that there was a significant difference between the level of happiness and psychological well being in parents of autistic and non autistic children. Moreover, there is a significant relation between happiness and psychological well being among the parents of autistic and non autistic children.
