The an.lysis of the win.-driven.self-excited in.uction.gen.rators （SEIGs） con.ected to the grid through power con.erters has been.developed in.this paper. For this an.lysis, a method of represen.in. the grid power as equivalen. load resistan.e in.the steady-state equivalen. circuit of SEIG has been.formulated. The techn.que of gen.tic algorithm （GA） has been.adopted for makin. the an.lysis of the proposed system simple an. straightfor- ward. The con.rol of SEIG is attempted by con.ectin. an.un.on.rolled diode bridge rectifier （DBR） an. a lin. commutated in.erter （LCI） between.the gen.rator term- in.ls an. three-phase utility grid. A simple con.rol techn.que for maximum power poin. trackin. （MPPT） in.win. en.rgy con.ersion.systems （WECS）, in.which the firin. an.le of the LCI alon. n.eds to be con.rolled by sen.in. the rotor speed of the gen.rator has been.proposed. The effectiven.ss of the proposed method of MPPT an. method of an.lysis of this win.-driven.SEIG-con.erter system con.ected to the grid through power con.erters has been.demon.trated by experimen.s an. simulation. These experimen.al an. simulated results con.irm the usefuln.ss an. successful workin. of the proposed system an. its an.lysis.

n.merical exercises are presen.ed on.the thermally in.uced motion.of in.ern.lly heated beams un.er various heat tran.fer an. structural boun.ary con.ition.. The dyn.mic displacemen. an. dyn.mic thermal momen. of the beam are an.lyzed takin. in.o con.ideration.that the temperature gradien. is in.epen.en. as well as depen.en. on.the beam displacemen.. The effect of len.th to thickn.ss ratio of the beam on.the thermally in.uced vibration.is also in.estigated. The type of boun.ary con.ition. has its in.luen.e on.the magn.tude of dyn.mic displacemen. an. dyn.mic thermal momen.. A sustain.d thermally in.uced motion.is observed with progress of time when.the temperature gradien. bein. evaluated is depen.en. on.the forced con.ection.gen.rated due to beam motion. A fin.te elemen. method (FEM) is used to solve the structural equation.of motion.as well as the heat tran.fer equation.

The ultraviolet upcon.ersion.lumin.scen.e of Tm3+ ion. sen.itized by Yb3+ ion. in.oxyfluoride n.n.phase vitroceramics when.excited by a 975 n. diode laser was studied. An.ultraviolet upcon.ersion.lumin.scen.e lin. position.d at 363.6 n. was foun.. It was attributed to the fluorescen.e tran.ition.of 1D2→3H6 of Tm3+ ion. Sev- eral visible upcon.ersion.lumin.scen.e lin.s at 450.7 n., (477.0 n., 462.5 n.), 648.5 n., (680.5 n., 699.5 n.) an. (777.2 n., 800.7 n.) were also foun., which result respectively from the fluorescen.e tran.ition. of 1D2→3F4, 1G4→3H6, 1G4→3F4, 3F3→3H6 an. 3H4→3H6 of Tm3+ ion. The careful measuremen. an. an.lysis of the variation.of upcon.ersion.lumin.scen.e in.en.ity F as a fun.tion.of the 975 n. pumpin. laser power P prove that the upcon.ersion.lumin.scen.e of 1D2 state is partly a five-photon.upcon.ersion.lumin.scen.e, an. the upcon.ersion.lumin.s- cen.e of 1G4 state an. 3H4 state are respectively the three-photon.an. two-photon.upcon.ersion.lumin.scen.e. The theoretical an.lysis suggested that the upcon. version.mechan.sm of the 363.6 n. 1D2→3H6 upcon.ersion.lumin.scen.e is partly the cross en.rgy tran.fer of {3H4(Tm3+)→3F4(Tm3+), 1G4(Tm3+)→1D2(Tm3+)} an. {1G4(Tm3+)→3F4(Tm3+), 3H4(Tm3+)→1D2(Tm3+)} between.Tm3+ ion.. In.addition. the upcon.ersion.lumin.scen.e of 1G4 an. 3H4 state results respectively from the se- quen.ial en.rgy tran.fer {2F5/2(Yb3+)→2F7/2(Yb3+), 3H4(Tm3+)→1G4(Tm3+)} an. {2F5/2(Yb3+) →2F7/2(Yb3+), 3F4(Tm3+)→3F2(Tm3+)} from Yb3+ ion. to Tm3+ ion..

For each fin.te group E, let O（E） be a bin.ry relation.on.the set of all subgroups of E. If A an. B are subgroups of a fin.te group G, then.we say that the pair （A, B） en.oys the gradewise property （resp., gen.ralized gradewise property） in.G if G has a n.rmal series Г：1=G0≤G1≤Gt=Gsuch that for each i=1,...,t,we have （（A∩Gi）Gi-1/BGi-1/Gi-1）∈θ（G/Gi-1）（resp., we have （（A∩Gi）Gi-1/BGi-1/Gi-1）∈θ（G/Gi-1）Usin. these con.epts, we obtain.some n.w characterization. for solubility an. supersolubility of fin.te groups an. gen.ralize some kn.wn.results.

Microbial growth in.soil is mostly limited by lack of carbon.(C). However, addin. fresh, C-rich litter can.in.uce n.trogen.(n. limitation. We studied the effect of alleviatin. C an. n.limitation.in.high-pH (> 8) soils, soils expected to favor bacterial over fun.al growth. n.trogen.limitation.was in.uced by in.ubatin. soils amen.ed with C-rich substrate (starch or straw) for 4 weeks. Limitin. n.trien.s an. the effects of alleviatin. limitation.were then.studied by addin. C (as glucose) or n.(as n._4n._3) an. measurin. microbial growth an. respiration.after 4 d. In.n.n.amen.ed, C-limited soils, addin. C but n.t n.in.reased both microbial respiration.an. bacterial growth. In.n.limited, substrate-amen.ed soils, addin. C in.reased respiration. whereas addin. n.in.reased both microbial respiration.an. growth. In.ucin. n.limitation.by amen.in. with straw was most easily detected in.in.reased fun.al growth after the addition.of n. whereas with starch, on.y bacterial growth respon.ed to alleviatin. n.limitation. Compared to earlier results usin. a low-pH soil, the effect of substrate used to in.uce n.limitation.was more importan. than.pH for in.ucin. bacterial or fun.al growth after alleviatin. n.limitation. Furthermore, we foun. n. eviden.e that alleviatin. n.limitation.resulted in.decreased respiration.con.omitan. with in.reased microbial growth in.soil, suggestin. n. drastic chan.es in.C use efficien.y.

Pollution.from diffuse sources （pollution.from con.amin.n.s picked up an. carried in.o surface waters by stormwater run.ff） has been.iden.ified as a sign.fican. source of water quality problems in.the U.S. scien.ists an. en.in.ers con.in.e to seek solution. that will allow them to optimize existin. techn.logies an. develop n.w on.s that will provide the best possible protection.to people, wildlife, an. the en.iron.en.. This paper addresses the various pollutan.s or stressors in.urban.stormwater, in.ludin. flow （shear force）, pathogen., suspen.ed solids/sedimen., toxican.s （organ.c an. metals）, n.trien.s, oxygen.deman.in. substan.es, an. coarse solids. A broad overview of the pollutan.s removed an. the removal mechan.sms by an. of con.en.ion.l best man.gemen. practices （BMPs） is also presen.ed. The prin.ipal treatmen. mechan.sms of con.en.ion.l wet pon.s, vegetative swales/ buffer strips, an. wetlan.s are sedimen.ation.an. filtration. These mechan.sms have the capability to remove sig- n.fican. amoun.s of suspen.ed solids or particulate matter an. are a vital compon.n. of strategies to reduce pollutan. loads to receivin. waters. In.addition. because most of the n.tion.s receivin. water violation. are caused by pathogen.in.icator bacteria, it is of utmost importan.e that research efforts address this problem. Further research is also n.eded on.the treatmen. of emergin. con.amin.n.s in.BMPs an. on.the costs an. affects of main.en.n.e an. main.en.n.e schedules on.the lon.-term performan.e of BMPs.
