Gi.en the abi.i.y of bui.di.g i.formati.n models （Bi.） to serve as a multi.i.ci.li.ary data reposi.ory, thi. study attempts to explore and exploi. the sustai.abi.i.y value of Bi. i. deli.eri.g bui.di.gs that requi.e less energy for operati.ns, emi. tess carbon di.xi.e, and provi.e conduci.e li.i.g envi.onments for occupants. Thi. objecti.e was attai.ed by a cri.i.al and extensi.e li.erature revi.w that covers the followi.g：（1） bui.di.g energy consumpti.n, （2） bui.di.g energy performance and analysi., and （3） Bi. and energy assessment. Li.erature ci.ed i. thi. paper shows that li.ki.g an energy analysi. toot wi.h a Bi. model has helped project desi.n teams to predi.t and create opti.i.ed energy consumpti.n by conducti.g bui.di.g energy performance analysi. uti.i.i.g key performance i.di.ators on average thermal transmi.ters, resulti.g heat demand, li.hti.g power, solar heat gai.s, and venti.ati.n heat losses. An i.-depth analysi. was conducted on a completed Bi. i.tegrated constructi.n project uti.i.i.g the Arboleda Project i. the Domi.i.an Republi. to vali.ate the aforementi.ned fi.di.gs. Results show that the Bi.-based energy analysi. helped the desi.n team attai. the world＇s fi.st posi.i.e energy bui.di.g. Thi. study concludes that li.ki.g an energy analysi. tool wi.h a Bi. model helps to expedi.e the energy analysi. process, provi.e more detai.ed and accurate results, and deli.er energy-effi.i.nt bui.di.gs. Thi. study further recommends that the adopti.n of level 2 Bi. and Bi. i.tegrati.n i. energy opti.i.ati.n analysi. must be demanded by bui.di.g regulatory agenci.s for all projects regardless of procurement method （i.e., government funded or otherwi.e） or si.e.

Au nanoparti.les are expected for the medi. to transfer genes i.to plants. However, the control of parti.le si.e di.tri.uti.n （PSD） and shape of Au nanoparti.les i. too di.fi.ult to desi.n and prepare parti.les wi.h sui.able quali.y for the gene supporti.g medi.. Reducti.n crystal- li.ati.n experi.ents were performed i. aqueous soluti.n i. order to clari.y the effect of feedi.g condi.i.ns such as feedi.g profi.e, feedi.g rate, and feedi.g amount on PSD and shape of Au nanoparti.les. Ascorbi. aci. （AsA） was selected as a reduci.g agent because i. i. safe for plants. Au parti.les of 50nm, 50-200nm, and 150-400nm were obtai.ed i. batch operati.n, si.gle-jet, and double-jet, respecti.ely. Moreover, i. si.gle-jet and double-jet, the mean si.e of the obtai.ed Au parti.les i.creases wi.h the decrease of feedi.g rate or the i.crease of feedi.g amount. i. i. concluded that PSD of Au nanoparti.les can be controlled i. the range of 50-400 nm by changi.g feedi.g condi.i.ns of AsA and HAuCl4 aqueous soluti.n.

CR-39 detectors have been exposed to a 5.9-MeV anti.roton beam usi.g the low energy anti.roton ri.g （LEAR） faci.i.y at CERN. At thi. energy, tracks of anti.rotons appear i. a CR-39 detector after 135 rai. of etchi.g i. 6M NaOH at 70℃. Fluence of the anti.roton beam has been determi.ed usi.g track densi.y. We have also found tracks i. the etched CR-39 detector at di.ferent depths （250-500μm）. These tracks have resulted from the anni.i.ati.n of anti.rotons wi.h the consti.uents （H, C and O） of the CR-39 detector. The goal of the experi.ent i. to develop a si.ple and low-cost method to study properti.s of anti.arti.les and those formed after anni.i.ati.n of these parti.les wi.h the target matter.

A two-step Taylor-Galerki. fracti.nal-step fi.i.e element method, whi.h i. of second order accuracy i. space and ti.e, was proposed for the three-di.ensi.nal free surface problem. Wi.h thi. method, the i.termedi.te veloci.y was expli.i.ly obtai.ed by neglecti.g pressure gradi.nt term, and then the veloci.y was corrected by addi.g the effects of pressure once the pressure fi.ld had been obtai.ed from the pressure Poi.son equati.n. The level set approach was appli.d to track i.pli.i.ly the free surface. i. order to track the free surface, the transport equati.n of the level set functi.n was solved at each ti.e step and the level set functi.n i. rei.i.i.li.ed through i.erati.n to mai.tai. i. as a di.tance functi.n. The governi.g equati.ns of the system were di.creti.ed by the two- step Taylor-Galerki. method, whi.h i. of hi.h-order accuracy and easy to be used. The vali.i.y and reli.bi.i.y of thi. method i. thi. arti.le were proved by two numeri.al examples.

The ferromagneti. anti.esonance （FMAR） phenomenon, i.e., the mi.i.um of the mi.rowave absorpti.n, i. polycrystalli.e La0.49Sr0.51MnO3 i. observed near Curi. temperature TC = 282 K. Temperature-dependences of magneti.ati.n μ0M are obtai.ed from the FMAR. The results show that as μ0H = 0, by fi.ti.g the scali.g law M ∝ （TC -T）^β to temperature-dependences of μ0M at the di.ferent mi.rowave frequenci.s, i. yi.lds TC=281.2 K and β = 0.47. However, temperature-dependences of μ0M under di.ferent μ0H are not i. agreement wi.h the scali.g law. Due to FMAR, about 40% gi.nt mi.rowave magneto-i.pedance at 11.9 GHz can occur under a low fi.ld μ0H = 0.03 T.
