The.pre.ale.ce.of multi drug re.istant gram-ne.ative.bacte.ia to commonly first line.drugs in blood is a se.ious proble. in e.uatorial Guine. and othe. world. This is the.first study de.cribing antibiotic re.istance.analysis of blood stre.m infe.tion in e.uatorial Guine.. Our study pre.e.ts alarming rate.of ine.ficie.cy of the.most commonly pre.cribe. drugs to tre.tme.t Kle.sie.la pne.moniae. e.che.ichia coli and Acine.obacte. spe.ie. isolate. as the.most fre.ue.cy e.iologic age.ts in blood stre.m infe.tion. Out of 1849 blood culture.the.bacte.ial e.iological age.ts we.e.isolate. from 196 (10.6%) sample.. e. coli (n = 22), K. pne.monia (n = 39) and Acine.obacte.

It is e.pe.ially worth noting the.low e.ficie.cy of third ge.e.ation ce.halosporins (Ce.rtiaxon) against Acine.obacte. and Kle.sie.la with the.r re.istance.rate.of 94.7% and 100% re.pe.tive.y.

在交通运输工业中,所使用的弹性体类型都随着使用条件的变化而不断地发生变化。例如,氟弹性体(FKM)在许多应用中随着操作温度的提高而在逐渐的代替丁腈橡胶(NBR)和耐低温(工作温度较低的)的其它一些聚合物。而操作条件也随着为在较高的温度下以及较大的使用范围内能够提供较好的应用而研制的新型流体在变化。这些新的条件都会以不同的、以前试验过的方式影响着弹性体。从而为要研制“新一代”的弹性体和改进现有的弹性体创造了良机。

介绍了染料敏化分解水制氢的基本原理。综述了染料分子的选取,使用氧化还原调节剂的机理和研究进展。指出染料分子对光谱的吸收特性,激发态染料分子能级与半导体导带的相对位置,染料分子与半导体的吸附情况,表面键合强度直接影响对光子的吸收,电子的注入,从而影响产氢量。此外,I-/I3-作为氧化还原调节剂可有效还原染料分子,实现持续产氢。最后提出了染料敏化分解水制氢的间歇式反应器结构,以及通过选择用于敏化的半导体来提高产氢率的思路。
