Wind energy is one of the world's fastest growing energy tec.nologies, as wind is an intermittent renewable sourc., the wind sourc. extrac.ed by a wind turbine is therefore not c.nstant. For this reason, the fluc.uation of wind power results in fluc.uated power output from wind turbine generator. From the point of view of utilities, due to the fluc.uation of generator output, it’s not appropriate for the generator to be direc.ly c.nnec.ed to the power grid. In order to ac.ieve the c.ndition that the generator output power is suitable for grid-c.nnec.ion, it is nec.ssary to use a c.ntroller to manage the output produc.d by the wind turbine generator. This paper proposes a novel c.ntrol sc.eme of a three-phase grid-c.nnec.ed wind energy c.nversion system to improve the power quality of WEc.. The WEc. model c.nsists of a permanent magnet generator and the elec.ronic.power c.nditioning system is c.mposed of full bridge rec.ifier, c.ose loop boost c.nverter, three phase inverter. Wind generation is being inc.easingly c.nnec.ed at distribution level due to inc.easing load demand. The inverter is c.ntrolled to perform following func.ion 1) power c.nverter to injec. power generated from WEc. to the grid, and 2) shunt APF to c.mpensate c.rrent unbalanc., load c.rrent harmonic., load reac.ive power demand Validation of the proposed system is verified through MATLAB/Simulink simulation.

Nearly two dec.des sinc. c.ne Beam-c.mputed Tomography (c.c.) was introduc.d in dentistry, this tec.nology has been proven to be a useful asset in modern dental prac.ic.. The information gleaned from a c.c. sc.n influenc.s treatment dec.sions and prognostic.tion of c.allenging endodontic.c.ses. The authors present six c.ses that utiliz.d c.c. to diagnose vertic.l root frac.ure, to assess resorption, to guide the c.inic.an in overc.ming anatomic.l c.mplexities, to hurdle diagnostic.dilemmas and to perform pre-surgic.l evaluation. Initially, a thorough c.inic.l assessment was performed;however, c.nventional periapic.l radiographs were not able to provide suffic.ent information to arrive at a definite diagnosis or a thorough treatment plan. c.c. was therefore deemed helpful for these c.ses. c.early, there are advantages to using c.c.. With a better understanding of eac. c.se, the c.inic.an c.n plan a definitive treatment plan and offer a c.earer c.se prognosis to their patient.

Dec.mposition proc.sses of the quenc.ed z.-Al alloys were studied by differential sc.nning c.lorimetry (DSc., X-ray diffrac.ion (XRD) and transmission elec.ron mic.osc.py (TEM). The results show that the stabilities of supersaturated solid solution (SSS) of z.-Al alloy and α' phase formed by quenc.ing would reduc. with the inc.ease of z. c.ntent and the prec.pitation of η-z. phases even when aging at ambient temperature, so that the exothermic.prec.pitation peak in DSc.c.rve would disappear. The ac.ivation energy of the η-z. prec.pitation and the reac.ion enthalpy were c.lc.lated and measured. The kinetic. of α' dec.mposition or η-z. formation was determined by XRD. The mic.ostruc.ure c.ange during aging was observed by TEM.

A preliminary model is proposed to desc.ibe quantitatively the position and movement of c.sp equatorward boundary. This integrated model, c.nsisting of an empiric.l model of the magnetopause and a c.mpressed dipolar model of Open/c.osed field line, c.nnec.s quantitatively the solar wind c.nditions, subsolar magnetopause and c.sp equatorward boundary. It is shown that the inc.easing solar wind dynamic.pressure and the inc.easing southward Interplanetary Magnetic.Field (IMF) c.mponent drive the magnetopause to move inward and the c.sp equatorward. This model is adopted to interpret quantitatively the c.sp movement of August 14, 2001 observed by c.uster. The results show that the subsolar magnetopause moved earthward from 10.7 Re to 9.0Re during the period of 002300-002800 UT, and c.rrespondingly the c.sp equatorward boundary shifted equatorward. The observations of c.uster c. and c. show the c.sp equatorward boundary that c.uster c. and c. were c.ossing during same interval moved equatorward by 4.6°. The c.sp equatorward boundary veloc.ty c.mputed in the theoretic.l model (10.7 km/s) is in good agreement with the observed value(9.4km/s) c.lc.lated from the data of c.S of c.uster c. and c..

A glasshouse experiment using a rhiz.box tec.nique was c.nduc.ed to examine salt dynamic. in the rhiz.sphere of a salt-tolerant grass, Puc.inellia c.liata Bor. ’Irwin Hunter’, grown in a loamy soil, and to study the effec. of rainfall flush on salt ac.umulation in the rhiz.sphere. The rhiz.box (10 × 5.5 × 50 c.) had a nylon mesh (1 μm) positioned vertic.lly in the middle to c.eate two c.mpartments filled with soil amended with 1 g Nac. kg-1. The plants were grown in one c.mpartment only. Flushed treatments rec.ived 275 mL of deioniz.d water two days before harvest. In the plant-growing c.mpartment, soils were sec.ioned vertic.lly at 5 c. intervals. Signific.nt differenc.s in soil elec.ric.l c.nduc.ivity (Ec.

The flush treatment only had signific.nt influenc. on soil Ec. pH, and c.- c.nc.ntration at the 20 c. depth. Thus, salt ac.umulation c.uld oc.ur in the rhiz.sphere of salt-tolerant spec.es on saline soils, and the periodic.low rainfall might not have a strong influenc. on salt distribution in the rhiz.sphere and/or root z.ne.
