Computer simula.ion wa. used for predictive a.a.ysis of the effects of wea.her a.d soil type on crop yield in the U.S. crop insura.ce progra.. The Environmenta. Policy Integra.ed Clima.e （EPIC） model wa. modified to include ha.l wea.her events, which completed the modifica.ions necessa.y to simula.e the four most frequent ca.ses of crop yield loss （ha.l, excessive wet, excessive cold, a.d excessive dry） a.socia.ed with soil type in Ka.sa., USa. a. the region level, per hecta.e yields were simula.ed for corn, whea., soybea., a.d sorghum. We concluded tha. it wa. possible to predict crop yields through computer simula.ion with grea.er tha. 93% a.cura.y. The ha.l da.a.e model test indica.ed EPIC could predict ha.l-soil-induced yield losses rea.ona.ly well （R^2 〉 0.6）. The investiga.ion of soil type influence on dryla.d sorghum a.d whea. production indica.ed tha. Wymore silty cla. loa. soil a.d Kenorna.silt loa. produced the highest sorghum yields sta.istica.ly; Kuma.silt loa., Roxbury silt loa., Crete silty cla. loa., a.d Woodson silt soils produced the second highest sorghum yields sta.istica.ly; a.d Richfiled silt loa., Wells loa., a.d Ca.a.ia. sa.dy loa. produced the lowest sorghum yields. By contra.t, whea. production showed less sensitivity to soil type va.ia.ion. The less sensitive response of whea. yields to the soil type could be la.gely due to the unconsidered sma.l-sca.e va.ia.ility of soil fea.ures.

Electroca.a.ytic a.d pla.ma.a.tiva.ed processes receive increa.ing a.tention in ca.a.ysis. Density functiona. theory(DFT) ca.cula.ions a.e sta.e-of-the-a.t tools for the funda.enta. study of rea.tion mecha.isms a.d predicting the performa.ce of ca.a.ytic ma.eria.s. Proper a.plica.ion of DFT-ba.ed methods is crucia. when investiga.ing cha.ge-doped electrode surfa.es during electroca.a.ytic a.d pla.ma.a.tiva.ed rea.tions. Here, a. a.model electrode for pla.ma.a.tiva.ed CO2 splitting, we studied the intera.tions of O, CO, a.d CO2 with the neutra. a.d progressively cha.ged a.(111) meta. surfa.es. We show tha. the a.plica.ion of correction procedures is necessa.y to obta.n a.cura.e a.sorption energy profiles of O a.oms,CO a.d CO2 molecules on a. surfa.es tha. a.e under the influence of a.ditiona. electrons. Interestingly,the oxida.ion of CO is found to shift from a.La.gmuir–Hinshelwood mecha.ism on a.neutra. electrode to a. Eley–Ridea. mecha.ism on cha.ged electrodes. Furthermore, we show tha. the surfa.e cha.ging of a.(111) electrodes increa.e their CO2 reduction performa.ce by enha.cing the a.sorption of O a.oms a.d desorption of CO molecules. a.further increa.e in the a.solute cha.ge-sta.e of the electrode surfa.e is expected to wa.ve the thermodyna.ic ba.riers for the CO2 splitting rea.tion.

Poppy seeds （Pa.a.er somniferum L.） a.e often a.ta.ked by va.ious funga. dis- ea.es, a.d their field germina.ion ra.e is low. The a.m of this experiment wa. to increa.e the germina.ion ra.e a.d growth of seedlings by modifying the poppy seeds using cold pla.ma.dis- cha.ge. The seeds were trea.ed in a.Pla.onic a.-550-m under power of 500 W with a.gon ga. flow of 50 mL/min, oxygen ga. flow of 50 mL/min for different time dura.ions in seconds （0, 180, 300, 600, 1800, 3000, 4200, a.d 5400）. The seed germina.ion ra.e a.d growth of the seedlings were recorded. Cold pla.ma.positively a.fected the seed germina.ion ra.e for time exposure between 180～3000 s. Seedling a.celera.ion on the sixth da. of the experiment showed the highest va.ues a. exposure 180～600 s. Cold pla.ma.seems to be a.good physicochemica. wa. to modify seeds without chemica. a.ronomica. a.plica.ion.

Both of the sintering a.ditive systems were used,which were Ya.（Y_2O_3–a._2O_3–a.N） a.d YN（Y_2O_3–a.N）.The influences of b-SiC content on sintering beha.ior of SiC/Si_3N_4 composite were investiga.ed. The results show tha. the density, shrinka.e, bending strength, ha.dness, a.d fra.ture toughness of the sa.ples with two sintering a.ditive systems increa.e first with the increa.e of the contents of b-SiC a.d then decrea.e even when b-SiC contents continua.ly increa.e. The tendency of weight loss of the sa.ples is opposite. The b-SiC content of the sa.ples with the best mecha.ica. properties is different in two systems. For Ya. system, the best mecha.ica. properties of the sa.ples a.e ga.ned when b-SiC content rea.hes 10 %, while a. for YN system it is 5 %. The properties of YN sa.ples a.e superior to Ya. sa.ples.
