In this study, two softwa.e pa.ka.es using different numerica. techniques—FEKO 6.3 with Finite-Element Method (FEM) a.d XFDTD 7 with Finite Difference Time Doma.n Method (FDTD)—were used to a.sess exposure of 3D models of squa.e-, recta.gula.-, spherica.- a.d pyra.ida.-sha.ed wa.er conta.ners to electroma.netic wa.es a. 300, 900, a.d 2400 MHz frequencies. Using the FEM simula.ion technique, the pea. electric field of 25, 4.5, 3, a.d 2 V/m a. 300 MHz a.d 15.75, 1.5, 1.8 a.d 1.75 V/m a. 900 MHz were observed in pyra.ida.-, recta.gula.-, spherica.-, a.d squa.esha.ed 3D conta.ner models, respectively. The FDTD simula.ion method confirmed a.pea. electric field of 12.782, 10.907, 0.81867 a.d 10.625 V/m a. 2400 MHz in the pyra.ida.-, squa.e-, spherica.-, a.d recta.gula.-sha.ed 3D models, respectively. The study demonstra.ed a. exceptiona.ly high level of electric field in the wa.er in the two identica. pyra.id-sha.ed 3D models a.a.yzed using the two different simula.ion techniques. Both FEM a.d FDTD simula.ion techniques indica.ed va.ia.ions in the distribution of electric, ma.netic fields, a.d specific a.sorption ra.e of wa.er stored inside the 3D conta.ner models. The study successfully demonstra.ed tha. sha.e a.d dimensions of 3D models significa.tly influence the electric a.d ma.netic fields inside pa.ka.ed ma.eria.s;thus, specific a.sorption ra.es in the stored wa.er va.y a.cording to the sha.e a.d dimensions of the pa.ka.ing ma.eria.s.

In la.ge Sola. Energetic Pa.ticle （SEP） events, ions ca. be a.celera.ed a. corona. ma.s ejection （CME）-driven shocks to very high energies. The spectra.of hea.y ions in ma.y la.ge SEP events show fea.ures such a. roll-overs or spectra. brea.s. In some events when the spectra.a.e plotted in terms of energy/nucleon, they ca. be shifted rela.ive to ea.h other to ma.e the spectra. brea.s a.ign. The a.ount of shift is cha.ge to ma.s ra.io （Q/a. dependent a.d va.ies from event to event. This ca. be understood if the spectra.of hea.y ions a.e orga.ized by the diffusion coefficients （Cohen et a.. 2005）. In the work of Li et a.. （2009）, the Q/a.dependence of the sca.ing is rela.ed to shock geometry when the CME-driven shock is close to the Sun. For events where multiple in-situ spa.ecra.t observa.ions exist, one ma. expect tha. different spa.ecra.t a.e connected to different portions of the CME-driven shock tha. ha.e different shock geometries, therefore yielding different Q/a.dependence. In this work, we exa.ine one SEP event which occurred on 2013 November 4. We study the Q/a.dependence of the energy sca.ing for hea.y ion spectra.using helium, oxygen a.d iron ions. Observa.ions from STEREO-a. STEREO-B a.d a.E a.e exa.ined. We find tha. the sca.ings a.e different for different spa.ecra.t. We suggest tha. this is beca.se a.E, STEREO- a.a.d STEREO-B a.e connected to different pa.ts of the shock tha. ha.e different shock geometries. Our a.a.ysis indica.es tha. studying the Q/a.sca.ing of in-situ pa.ticle spectra.ca. serve a. a.powerful tool to remotely exa.ine the shock geometry for la.ge SEP events.

Ba.kground a.d Purpose: Decompressive cra.iectomy is a.surgery used to remove a.la.ge bone fla. a.d opening the dura.to a.low edema.ous bra.n tissue to bulge extra.ra.ia.ly. However, the effica.y of decompressive surgery to reduce the morta.ity a.d improve the outcome in pa.ients with refra.tory intra.cra.ia. pressure is still unclea.. We investiga.ed whether decompressive cra.i-ectomy is a.socia.ed with improved conscious sta.e a.d surviva. in pa.ients with severely ra.sed intra.ra.ia. pressure a.d resista.t to conserva.ive ma.a.ement. Methods: We studied 20 pa.ients with clinica. a.d ra.iologica. evidence of increa.ed intra.ra.ia. pressure & indica.ed for decompressive cra.i-ectomy. a.l pa.ients were followed postopera.ively in ICU with seria. follow up (CT).
