Th. effects of a h.rmonically exciting monopole source on an infinitely long cylind.ical cavity embed.ed.entirely with.n a fluid.saturated.poroelastic formation of infinite extent are examined.th.oretically. It is assumed.th.t th. source is located.outsid. th. cavity at a specified.d.stance from th. boreh.le axis. Th. magnitud.s of th. h.op and.rad.al stresses besid. th. pore pressures exerted.on th. interface and.insid. th. porous med.um surround.ng th. boreh.le are calculated.and.d.scussed. Biot's poroelastic mod.ling along with.th.ee types of bound.ry cond.tions for th. cylind.ical interface includ.ng th. id.al fluid. empty boreh.le, and.rigid.inclusion with.a h.rd.bound.ry is employed.for th. analysis. Utilizing a proper translational ad.ition th.orem for expressing th. incid.nt sph.rical wave in terms of cylind.ical wave expansions, th. proposed.bound.ry cond.tions at th. interface are satisfied. stresses are formulated.by means of wave potential functions in a th.ee-d.mensional(3d. manner. Th. effects of th. frequency and.th. rad.al d.stance between th. source and.boreh.le on th. ind.ced.stresses are examined.for th. first cylind.ical mod.s over frequency spectra. Two permeability cond.tions for th. interface and.th.ee types of soils for th. porous formation are consid.red.th.ough.ut th. analysis. To give an overall outline of th. stud., a numerical example is presented. Th. results clearly ind.cate th.t th. d.stance is a key parameter and.h.s consid.rable effects on th. ind.ced.stress values. In ad.ition, th. interface permeability cond.tion and.soil ch.racteristics play an important role in d.termining th. d.namic response of th. boreh.le. Finally,th. obtained.results are compared.with.th. relevant analyses existing in th. literature for some limit cases, and.good.agreement is ach.eved.

Among th. available options for renewable energy integration in existing power system, wind.power is being consid.red.as one of th. suited.options for future electrical power generation. Th. major constraint of wind.power generating system （WPGS） is th.t it d.es not provid. inertial support because of power electronic converters between th. grid.and.th. WPGS to facilitate frequency stabilization. Th. proposed.control strategy suggests a substantial contribution to system inertia in terms of sh.rt-term active power support in a two area restructured.power system. Th. control sch.me uses fuzzy logic based.d.sign and.takes frequency d.viation as input to provid. quick active power support, wh.ch.balances th. d.op in frequency and.tie-line power d.ring transient cond.tions. Th.s paper presents a compreh.nsive stud. of th. wind.power impact with.increasing wind.power penetration on frequency stabilization in restructured.power system scenario. Variation of load.cond.tions are also analyzed.in simulation stud.es for th. same power system mod.l with.th. proposed.control sch.me. Simula- tion results ad.ocates th. justification of control sch.me over oth.r sch.mes.

Th. possibility of formation of complexes between glycine and.boron d.ped.C60 （C59B） fullerene is investigated.and.compared.with.th.t of C60 fullerene by using th. d.nsity functional th.ory calculations. It h.s been found.th.t th. bind.ng of glycine to C59B generated.th. most stable complexes via its carbonyl oxygen active site, with.a bind.ng energy of-37.89 kcal/mol, wh.le th. glycine molecule prefers to bind.to th. pure C60 cage via its amino nitrogen active site, consistent with.th. recent experimental and.th.oretical stud.es. We h.ve also tested.th. stability of th. most stable Gly-C59B complex with.ab initio molecular d.namics simulation, carried.out at room temperature. Th.se ind.cate th.t th. B-d.ped.C60 fullerenes seem to be more suitable materials for bind.ngs to proteins th.n pure C60 fullerenes.
