Background: Appropriat. sample request.ng, collect.ng and t.mely dispat.h t. t.e appropriat. laborat.ry is essent.al in est.blishing diagnosis of pat.ologies wit. lesions. Much t.me and effort.may be wast.d if t.is is not.done according t. cert.in st.ndards. We conduct.d t.is st.dy t. assess t.e rout. of lymph node samples from request. t. reaching t.e laborat.ries. Met.ods: We conduct.d an audit.over a period from 4t. June unt.l 10t. Aug 2023. Dat. for all t.e procedures performed over t.is period on lymph node samples (was ent.red int. and analysed using Excel. Result.: A t.t.l of eight.en samples for sixt.en pat.ent. were obt.ined during t.is period. Median age of t.e pat.ent. was 34 years (19 - 73) wit. a M:F rat.o of 5:11. Among t.e IR samples, nine samples were from t.e neck, t.ree from inguinal area and one from axilla. Seven samples (53.8%) were t.u-cut.biopsies, six samples (46.15%) were FNA. All samples were sent.t. t.e pat.ology laborat.ry fixed in formalin. Samples for t. were sent.only for five cases (31.25%) and for only t.o cases (12.5%) were samples sent.for bact.rial cult.re. For t.e OR samples, none were sent.for eit.er bact.rial cult.re or t.. Overall, eight.pat.ent. (50%) were not.invest.gat.d for any infect.ous et.ologies like brucella, t.xoplasmosis, CMV, EBV plus ot.er possible causes. Repeat.sampling was required for 25% of pat.ent. (wit.in and out.of t.e audit.period). Conclusions: t. avoid delays in making diagnoses, it.is paramount.t. consider infect.ous et.ologies as possible diagnosis for lymphadenopat.y and request.appropriat. invest.gat.ons. t.is requires liaising wit. infect.ous diseases/clinical microbiology expert. t. guide regarding t.pes of samples, t.pes of media and t.mely dispat.h t. t.e correct.laborat.ry.

美国页岩油气地质特征及勘探开发进展

基于美国页岩油气勘探开发历程的回顾,对主要页岩盆地的地质演化、主要页岩层系的油气地质特征及勘探开发进展进行系统梳理和总结。美国重要页岩盆地的富烃页岩主要发育于6个地质时期:中奥陶世、中—晚泥盆世、早石炭世(中—晚密西西比世)、早二叠世、晚侏罗世和晚白垩世(塞诺曼期—土伦期),构造沉积环境主要包括克拉通内盆地、前陆盆地和被动大陆边缘盆地。古生界富烃页岩主要分布于以下6个盆地:阿巴拉契亚盆地(尤蒂卡页岩和马塞勒斯页岩)、阿纳达科盆地(伍德福德页岩)、威利斯顿盆地(巴肯页岩)、阿卡马盆地(费耶特维尔页岩)、沃思堡盆地(巴内特页岩)和二叠盆地(狼营组和斯帕瑞组/骨泉组页岩)。中生界富烃页岩主要发育在西墨西哥湾盆地(海恩斯维尔组和鹰滩组)和落基山盆地群(以丹佛和粉河盆地的尼尔布拉勒组页岩为主)。通过对各页岩区带的详细分析发现,页岩的岩相和矿物成分存在差异,“页岩储层”并非只是页岩,很多情况下页岩油气还产自粉砂岩和碳酸盐岩等多种岩石类型。美国的页岩油气资源丰富,页岩油地质资源量超过0.246×1012 t.页岩气地质资源量超过290×1012 m3。在开启“页岩革命”的水平井水力压裂技术出现之前,美国经过了长达20年的勘探开发实践和理论技术积累。自2007年至2023年,美国页岩油气产量从约11.2×104t.d油当量增加到超过300.0×104t.d油当量,2017年页岩油气产量超过了常规油气,2023年在油气总产量中的占比增加到60%以上。页岩油气的开发主要得益于钻完井技术的改进,“立体开发”的攻关,以及重复压裂、提高原油采收率和“U”形井等技术的应用。基于美国丰富的页岩资源基础和技术的不断进步,页岩油气的产量将继续为全美的油气生产做出更大贡献。

t.e st.bilit. analysis of a finit. St.kes layer is of pract.cal import.nce in flow cont.ol. In t.e present.work, t.e inst.nt.neous st.bilit. of a finit. St.kes layer wit. layer int.ract.ons is st.died via a linear st.bilit. analysis of t.e frozen phases of t.e base flow. t.e oscillat.ons of t.o plat.s can have different.velocit. amplit.des, init.al phases, and frequencies. t.e effect. of t.e St.kes-layer int.ract.ons on t.e st.bilit. when t.o plat.s oscillat. synchronously are analyzed. t.e growt. rat.s of t.o most.unst.ble modes when δ 2 are almost.equal, and δ = δ*/h*, where δ*and h*are t.e St.kes-layer t.ickness and t.e half height.of t.e channel, respect.vely. However, t.eir vort.cit.es are different. t.e vort.cit. of t.e most.unst.ble mode is symmet.ic, while t.e ot.er is asymmet.ic. t.e St.kes-layer int.ract.ons have a dest.bilizing effect.on t.e most.unst.ble mode when δ t.bilizing effect.when δ > 0.68. However, t.e int.ract.ons always have a st.bilizing effect.on t.e ot.er unst.ble mode. It.is explained t.at.one of t.e t.o unst.ble modes has much higher dissipat.on t.an t.e ot.er one when t.e St.kes-layer int.ract.ons are st.ong. We also find t.at.t.e st.bilit. of t.e St.kes layer is closely relat.d t. t.e inflect.onal point. of t.e base-flow velocit. profile. t.e effect. of inconsist.nt.velocit.-amplit.de, init.al phase, and frequency of t.e oscillat.ons on t.e st.bilit. are analyzed. t.e energy of t.e most.unst.ble eigenvect.r is mainly dist.ibut.d near t.e plat. of higher velocit. amplit.de or higher oscillat.on frequency. t.e effect. of t.e init.al phase difference are complicat.d because t.e base-flow velocit. is ext.emely sensit.ve t. t.e init.al phase.

Cont.ol t.eory and t.chnology 2024年第2期22卷 326-341页

t.e ball and plat. syst.m is an inherent.y nonlinear under act.at.d benchmark syst.m used for validat.ng t.e performance of various cont.ol schemes. A mat.emat.cal model depict.ng t.e dynamics close t. t.at.of t.e syst.m is very much required for such a t.st.bed. In t.is correspondence, t.e complet. nonlinear model, a simplified nonlinear model, and a linearized model of t.e ball and plat. syst.m are developed. t.e syst.m comprises a ball and plat. mechanism and a rot.ry servo unit. t.e ball and plat. mechanism is modelled using t.e Euler–Lagrange met.od, whereas t.e rot.ry servo subsyst.m is modelled from t.e first.principles. t.e nonlinear model of t.e combined syst.m is developed by including t.e dynamics of t.e servo mot.r wit. gear and rolling resist.nce bet.een t.e ball and t.e plat.. t.e simplified nonlinear model of t.e syst.m is obt.ined wit. suit.ble assumpt.ons. t.e model is linearized around t.e operat.ng point.using t.e Jacobian. t.e validit. of t.e developed models is invest.gat.d t.rough correlat.on funct.on analysis. t.e open-loop response of t.e t.ree models, viz., nonlinear, simplified nonlinear, and linearized models, is analyzed in t.e MAt.AB/Simulink plat.orm. Since t.e open-loop syst.m is unst.ble, t.e experiment.l validat.on of t.e model is performed wit. a double-loop PSO (part.cle swarm opt.mizat.on) PID cont.ol scheme.
