The present study was conducted to quantify wood and leaf litter decomposition and nutrient release of a dominant tree species, Tectona grandis Linn. F. in a tropical dry deciduous forest of Rajasthan, Western India. The mean relative decomposition rate was maximum in the wet summer and minimum during dry summer. Rainfall and its associated variables exhibited greater control over litter decomposition than temperature. The concentrations of N and P increased in decomposing litter with increasing retrieval days. Mass loss was negatively correlated with N and P concentrations. The monthly weight loss was significantly correlated (P < 0.05) with soil moisture and rainfall in both wood and leaf litter. Tectona grandis was found to be most suitable tree species for plantation programmes in dry tropical regions as it has high litter deposition and decomposition rates and thus it has advantages in degraded soil restoration and sustainable land management.
Bioprospecting in a Tropical Dry Deciduous Forest of Western Rajasthan, India
J. I. Nirmal Kumar,P. R. Sajish,Rita. N. Kumar,Rohit Kumar Bhoi 강원대학교 산림과학연구소 2010 Journal of Forest Science Vol.26 No.1
Bioprospecting has been widely used to assess the economic potential of different plant species and their value-addition. Prospecting for biological material like plants with medicinal or other economically valuable properties like fibre or oil is becoming a dynamic activity. Our folklore with embedded cultural heritage has tremendous possibilities and potential for bioprospecting. This forest region of Western Rajasthan is enriched with diverse vegetational wealth, if subjected to bioprospecting may prove to be a boon for the society.

Hulthén Half-off-Shell T Matrix-Application to n-p and n-d Systems
A. K. Behera,U. Laha,P. Sahoo,J. Bhoi 한국물리학회 2020 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.76 No.9
In a previous paper, one of us (UL) constructed an exact analytical expression for the irregular (Jost) solution, off the energy shell, for the Hulthén potential by using the method of ordinary differential equation along with the properties of certain special functions of mathematical physics. In the present text, closed form expressions for the off-shell irregular solution and half-off-shell T-matrix for motion in the Hulthén potential are re-derived by using the direct integration approach to the problem under consideration. We demonstrate the usefulness of our expressions through some model calculations and achieve excellent agreement between bound-and scattering-state observables and standard results.
