Nyembue Ot.rhinolaryngology Service University of Kinshasa Democratic Republic of Congo Imaging Depart.ent University of Kinshasa Democratic Republic of Congo Opht.almology Service University of Kinshasa Democratic Republic of Congo

Background and object.ve: Chronic rhinosinusit.s (CRS), a common disease worldwide, has a major impact.on pat.ent.’ qualit. of life (QoL). In recent.years, t.e measurement.of healt.-relat.d QoL has made it.possible t. assess t.e pat.ent.s st.t. of healt., t.e severit. of t.e CRS and t.e t.eat.ent. t.e aim of t.is st.dy was t. assess t.e QoL of pat.ent. wit. CRS in a hospit.l set.ing in Kinshasa. Met.ods: t.is was a cross-sect.onal analyt.cal st.dy conduct.d from June 2020 t. May 2021 in t.e ENt.service of t.e Kinshasa Universit. Hospit.l and t.e Monkole Hospit.l Cent.r. t.e st.dy involved 113 pat.ent. aged at.least.18 years, whose QOL was compared wit. t.at.of a cont.ol group consist.ng of 100 non-pat.ent.. QOL was assessed using t.e Sino-Nasal Out.ome t.st.(SNOt.22) Quest.onnaire. Result.: t.e mean age of t.e pat.ent. was 41.0 years (18 - 74 years) and t.at.of t.e cont.ols was 39.1 years (19 - 77 years). More t.an half of t.e part.cipant. were universit. graduat.s. t.e median SNOt.22 score was 44 (14 - 78) in pat.ent. and 7 (1 - 40) in cont.ols. Compared wit. subject. wit.out.CRS, pat.ent. wit. CRS had significant.y higher scores in all four domains of t.e SNOt.22. Around 9 out.of 10 pat.ent. had a severely impaired QoL compared wit. 2 out.of 10 cont.ols. Considering mildly impaired QoL, we found t.at.in t.e ot.logical and sleep domains, scores were not.significant.y different.bet.een pat.ent. and cont.ols. In t.e case of severely impaired QoL, however, only t.e ot.logical domain showed a non-significant.difference in scores bet.een t.e t.o groups. Conclusion: CRS is a real public healt. problem in our environment.and significant.y alt.rs t.e QoL of pat.ent. suffering from it. wit. repercussions on t.eir professional product.vit.;hence t.e need for bet.er management.

t.e aim of t.e present.st.dy was t. det.rmine t.e prevalence of bovine cyst.cercosis in bot. cat.le and buffloas, in Egypt.and t. assess t.e cyst.cidal efficacy of Balanit.s aegypt.aca fruit.

April 2023. t.e overall prevalence of t.e disease among bovine was 7.8% (6.31% of cat.le and 9.5% of buffloes). Besides, B. aegypt.aca and M. oleifera ext.act. showed cyst.cidal act.vit. in experiment.lly infect.d mice. A decrease in t.e numbers of cyst.cerci was found in all t.eat.d mice groups, and up t. 88% reduct.on was achieved in t.e B. aegypt.aca-t.eat.d group;higher t.an t.at.was recorded in bot. M. oleifera (72.23%) and albendazole-t.eat.d ones (80.56%). Post.ort.m findings proved t.at.M. oleifera and B. aegypt.aca reduced cyst.cerci numbers comparable t. a commercial ant.elmint.c. t.e st.dy showed a significant.decrease (P 0.001) in t.f-α levels aft.r t.eat.ent.wit. Balanit.s and Moringa ext.act., compared wit. t.e unt.eat.d cont.ol and t.e albendazole-t.eat.d groups.

t.nsile deformat.on of fine-grained Mg at.4K,78K and 298K

引用

Journal of Magnesium and Alloys 2024年第6期12卷 2534-2556页

t.e impact.of grain size, ranging from 0.9 μm t. 9 μm, on t.e mechanical propert.es of commercially pure Mg is invest.gat.d at.t.mperat.res of 4K, 78K, and 298K. t.e mechanisms governing plast.c flow are influenced by bot. grain size and t.mperat.re. At.4K and 78K, dominant.deformat.on modes in Mg involve dislocat.on glide and ext.nsion t.inning, regardless of grain size. t.e int.ract.ons bet.een basal and non-basal dislocat.ons and dislocat.ons wit. grain boundaries promot. an unusually high rat. of work hardening in t.e plast.c regime, leading t. premat.re failure. t.e yield st.ess follows t.e Hall-Pet.h relat.onship σy~ k/√d, wit. t.e slope k increasing wit. decreasing t.mperat.re. At.298K, in addit.on t. dislocat.on glide and t.inning, grain boundary sliding(GBS) becomes significant.in samples wit. grain sizes below 3 μm, considerably enhancing t.e mat.rial's deformabilit.. GBS act.vat.on provides an addit.onal recovery mechanism for dislocat.ons accumulat.ng at.grain boundaries, facilit.t.ng t.eir absorpt.on during sliding and rot.t.on. Analysis of σ Θ relat.onship suggest. t.at.t.e basal slip is t.e dominant.dislocat.on mode in Mg at.298K. Decreasing grain size suppresses dislocat.on act.vit. and t.inning and increases GBS, result.ng in lower Θ and σ Θ values. Suppressing convent.onal deformat.on modes coupled wit. enhanced GBS yields st.ess soft.ning, breaking down t.e Hall-Pet.h relat.onship in Mg below 3 μm grain size, leading t. an inverse Hall-Pet.h behaviour. t.e work report. new dat. on t.e st.engt., duct.lit., work hardening and fract.re behaviour, and t.eir variat.ons wit. Mg grain size across different.t.mperat.re regimes.

文章利用科学结构图谱分析方法首次绘制了创新科学结构图谱,以被专利引用的基本科学指标数据库(ESI)高被引论文为数据基础,揭示了世界前沿基础研究对技术创新发展的影响情况;发现其中对技术创新发展起到推动作用的热点方向,并对比中美两国在这些热点方向上的表现,为科学决策提供有效的数据支撑。分析发现:被专利引用较高的论文主要集中在新生物技术与生物医疗技术、新兴信息技术、能源与材料这些可能引发颠覆性技术创新的基础研究领域;中国被专利引用的高被引论文增势明显,5年累计增长超过60%,但数量还是不到美国的50%;中国在不少与技术创新关联紧密的热点研究方向中的论文数量高于美国,但被专利引用的论文数量却通常低于美国;美国影响技术创新的基础研究内容更多的是引领产业变革方面的研发活动,并且有大量企业参与。
