ABSTRACT: In this study, the detailed analysis of excitation function of elliptical flow by taking into account the nature of equation of state, nucleon-nucleon (NN) cross sections as well as momentum dependent interactions is performed within Quantum Molecular Dynamics (QMD) model. All the physical parameters are found to sensitive towards the elliptical flow. The interesting observation from the study is that the transition energy is found to be decrease with increase in the size of the fragment in the presence of static equations of state and different NN cross sections, while trend gets opposite when momentum dependent interactions are included. Finally, experimental data of INDRA collaboration around the transition energy of 79Au197 +79 Au197 is verified with static hard equation of state in the presence of large cross section.

ABSTRACT: Mycorrhiza is the most important member of functional soil microbial community in natural ecosystem and creates an intimate link between plant roots and soil. In the present investigation, attempts were made to screen out endomycorrhizal biodiversity from different medicinal plants. A total of twelve plants from six different families were screened for arbuscular mycorrhizal (AM) spore number and root colonization. The mycorrhizal root colonization ranged from 0.0 to 67.50±10.60 percent. Adhatoda vesica showed maximum root colonization and Achyranthus aspera lack mycorrhizal root colonization. The spore number ranged from 25.66±3.00 to 388.33±8.50. The highest mycorrhizal spore count was found in Aster thomsonii and lowest in Aloe vera. It was found that number of spores in the rhizosphere of plant was not related to the intensity of AM root colonization. The study confirmed that the biodiversity of AM fungi differ in different plants. Keywords: medicinal plants; arbuscular mycorrhizal fungi; vesicles.

ABSTRACT: Chemical constitution of the fibrous material is not the only deciding factor for determining the nature of the pulp that may be made out of it. Much will depend upon the morphological properties, anatomical structure of the raw material and physical properties, in determining the yield and quality of the pulp. The study of wood of Morus Nigra was analyzed for the determination of its constituents and its suitability for pulp and paper manufacture. Physical and chemical analysis of the Morus Nigra species needs special attention while exploring its pulpability and Morus Nigra is analyzed by using TAPPI procedures. Keywords: Pulpability; Fibre Length; Luman Width; Acetyl Content.

ABSTRACT: Viscosity measurements of terbium octanoate in mixed organic solvent shows that there is marked change in the aggregation of the anionic species at critical micellar concentration (CMC). The effects of temperature on CMC have been reported. The viscosity results have been satisfactorily explained by various equations with their parameters. The result shows that there is a significant interaction between solute and solvent molecules. Keywords: micellar; CMC; terbium octanoate.

ABSTRACT: Although cancer has been considered as untreatable till now, but development of several biological agents have improved the survival and quality of life in some patients. A class of agents targeting epigenetic modifier enzymes have emerged with huge potential in cancer therapy. Novel compounds endowed with a histone deacetylase (HDAC) inhibitory activity and DNMT inhibitory activity are attractive therapeutic approach in recent time. Clinically, it is much simple to inhibit an enzyme than to induce one and this has directed the recent research to a new class of enzymes i.e. DNMT and HDAC. As a result of the earlier work it has become clear that HDACs are unique player in chromatin architecture, thus affect protein expression by altering the accessibility of Dna to the transcriptional machinery, which in turn affect transcriptional control and also activation of many tumour suppressor genes. Instead of it DNMTs are associated with hypermethylation of promoter and decrease its accessibility for transcriptional machinery. The extensive outcome of research in terms of structure, class, size etc. offers opportunities for the development of HDACi and DNMTi with improved specificity. In recent years, an increasing number of structurally diverse inhibitors have been identified that inhibit proliferation and induce differentiation and/or apoptosis of tumor cells both in-vitro and in-vivo. The question, that how epigenetic modifications associated with DNA or histones increases or decreases the accessibility of DNA to various factors that are involved in the reading of the DNA create interest in the researchers and lead to extensive research in this field. Keywords: HDAC; HDACi; DNMT; DNMTi; DNA.

ABSTRACT: Waste polyethylene terephthalate (PET) is glycolyzed along with virgin PET. A higher proportion of virgin PET in the mixture has the ability to consume more glycols during glycolysis. This gives rise to a glycolyzed PET (GPET1), which contains a lesser amount of free glycol and shows the highest hydroxyl value. During polyesterification of the polyester diol (glycolyzed PET) with maleic acid, the degree of polymerization (DPn), extent of reaction and acid value is observed to be increasing with an increase in the virgin PET content in the mixture. This is believed to be due to the increasing presence of BHET (bis-hydroxy ethylene terephthalate) in the glycolyzed PET. Keywords: Glycolyzed PET; BHET; polyesterification; hydroxyl value.

ABSTRACT: The fiscal reform at the state level is important from the viewpoint of both macroeconomic stability and microeconomic allocative efficiency. The Constitution assigns a pre-eminent role to states in agricultural development, poverty alleviation, human development and co-equal position in the provision of physical infrastructure. The predominant role in allocation and cooperative role in distribution makes states fiscal operations critical for macroeconomic stabilization as well. Although the Constitution places limitations on the states’ borrowing powers, in actual practice they are able to run large deficits and that makes fiscal reforms at the state level critical for achieving overall fiscal consolidation in the country. A state specific assessment of fiscal position assumes importance in view of the wide disparities that exist among the Indian states. So, the need of the hour is to frame an effective and time-bound policy measures to enhance revenues particularly non-taxes and shift in expenditure pattern towards economic growth of the state. This paper is an attempt to examine current programme options from the point of view of macro-economic stability and growth, study the public finance at state level and presents an analytical review and assessment of fiscal situation of Himachal Pradesh also examine the review of policy measures to strengthen the state finances and to bring down the fiscal deficit ratio to make a balance in the GDP, expected to lower inflation and interest rates in the economy and strengthen the sustainability of fiscal balance in the long run.
