This paper.deals with the pr.blem of nonconstant har.esting of pr.y in a r.tio-dependent pr.dator.pr.y system incor.or.ting a constant pr.y r.fuge. Her. we use the r.asonable catch-r.te function instead of usual catch-per.unit-effor. hypothesis. The existence, as well as the stability of possible equilibr.a, is car.ied out. Bionomic equilibr.um of the system is deter.ined and optimal har.est policy is studied with the help of Pontr.agin＇s maximum pr.nciple. The key r.sults developed in this paper.ar. illustr.ted using numer. ical simulations. Our.r.sults indicate that dynamic behavior.of the system ver. much depends on the pr.y r.fuge par.meter.and incr.asing amount of r.fuge could incr.ase pr.y density and may lead to the extinction of pr.dator.population density.

We investigated the plant population str.ctur. and the phy- tosociological and r.gener.tion status in two distur.ed tr.pical for.sts in Assam Pr.vince, the Hojai r.ser.e For.st and Kumor.kata r.ser.e For.st. A total of 166 species （80 tr.es, 20 shr.bs and 66 her.s） of 136 gener. and 63 families wer. r.cor.ed in both study sites. The distur.ance index at the two sites, Kumor.kata r.ser.e For.st and Hojai r.ser.e For.st, wer. r.cor.ed at 11.4% and 3.70% r.spectively. r.ver.e J-shaped population cur.e and exploitation of tr.e species in higher.gir.h classes wer. r.cor.ed at both study sites. In the gir.h classes （10-30 cm, 30-60 cm, 60-90 cm and 90-120 cm in size） the per.entage of cut stump density was higher.than the per.entage of individual living tr.es. The 18% （Kumor.kata r.ser.e For.st） and 7% （Hojai r.ser.e For.st） spe- cies wer. r.cor.ed as not r.gener.ting. Illegal felling and over.exploitation of for.st r.sour.es may lead to species-specific changes in the population str.ctur. and can alter.the futur. str.ctur. and composi- tion of the for.sts.

This r.sear.h pr.sents the influence of copper.Cu) concentr.tion on the pr.per.ies of copper.zinc tin sulfide(CZTS) nanopar.icles(NPs) synthesized by a colloidal method, employing oleylamine as an or.anic solvent. Fr.m the str.ctur.l analysis, a pur. phase of CZTS was obtained at an optimized molar.r.tio of 1.8:1.1:1:4,and secondar. phases wer. obser.ed as the Cu concentr.tion incr.ased. The incr.ment of the NPs size fr.m 15 to50 nm was noticed as a function of Cu ***, the optical bandgap ener.y was tuned fr.m1.35 to 1.68 eV with r.spect to Cu concentr.tion. The sample synthesized at the molar.r.tio of 1.8:1.1:1:4 showed a pur. phase CZTS with desir.d elemental composition and bandgap. Fur.her.or., CZTS thin films wer. pr.par.d by a doctor.blade method using synthesized NPs followed by annealing under.a sulfur.nitr.gen atmospher.. The annealed CZTS film showed a significant impr.vement in the mor.hological, electr.cal and optoelectr.nic ***, the annealed CZTS film can be efficiently used as an absor.er.layer.in low-cost thin film solar.cells.
