在不使用电能的情况下，化学镀依靠含有还原剂的水溶液中金属离子的催化还原，从而实现金属的沉积。其成功与否，很大程度上取决于温度的维护。温度升高，沉积速度加快，因此，应当避免热量散失到周围环境中。本文估算了包裹不同隔热材料的化学镀镍液的散热量。结果表明，采用棉花作为隔热材料，热损失可降至最低，从而提高并维持一定的沉积速率。

World Journal of Cardiovascular Diseases 2018年第7期8卷 390-401页

作者： Narendra Chanda D. Rajasekhar A. Ravi Kant. V. Vanajakshamma C. Kapil t. Suresh Babu K. Sreedhar Naik Depart.ent.of Cardiology Sri Venkateswara Institute of Medical Sciences Tirupati India

Int.oduct.on: Mit.al regurgit.t.on (MR) is a common valvular disease t.at.causes significant.morbidit. and mort.lit.. t.e use of mult.ple echocardiographic indices and hormonal paramet.rs in combinat.on can provide an accurat. assessment.of MR severit. and LV dysfunct.on in most.cases. Aim of st.dy: t.e aim of t.is st.dy was t. correlat. t.e levels of serum Nt.pro BNP wit. various echocardiographic paramet.rs including 3D vena cont.act. widt. in pat.ent. wit. MR. Met.ods: 74 Pat.ent. diagnosed wit. primary mit.al regurgit.t.on in sinus rhyt.m wit. no conduct.on dist.rbance were included in t.e st.dy. 2D and Doppler echocardiography indices were calculat.d. A full-volume 3D color Doppler acquisit.on was obt.ined and 3D vena cont.act. widt. was calculat.d and serum BNP levels were obt.ined. Result.: Nt.pro BNP levels were increased wit. sympt.ms in pat.ent. wit. mit.al regurgit.t.on (NYHAI: 4.48 ± 0.06, NYHAII: 5.54 ± 0.78, NYHAIII: 6.68 ± 1.21 pg/ml, p 0.01). Nt.pro BNP plasma levels were significant.y correlat.d wit. MPI (r = 0.945, p 0.01), LVESV (r = 0.706, p 0.01), LVESVI (r = 0.677, p 0.01), LAVI (r = 0.709, p 0.01), MR 2D VC (r = 0.430, p 0.01), 3D VC (r = 0.441, p 0.01), PISA (r = 0.440, p 0.01) and negat.ve correlat.on wit. LV eject.on fract.on (r = 0.846, p 0.01), dp/dt.(r = 0.795, p BNP plasma level and LA jet.area rat.o (P = 0.33). It.was observed t.at.t.ere was a significant.correlat.on bet.een 3D VC and PISA levels in pat.ent. of mit.al regurgit.t.on. However correlat.on is bet.er in MR wit. cent.al jet.compared t. eccent.ic jet.in moderat. and severe MR (r = 0.807, 0.817 vs r = 0.617, 0.572). Conclusion: t.is st.dy showed t.at.Nt.pro BNP measurement.has t.e same sensit.vit. and specificit. as echocardiographic indices. t.ree-dimensional VCA may provide a reliable measurement.of ROA, independent.of geomet.ic and flow assumpt.ons.

t.ends in 20 ext.eme indices of t.mperat.re and precipit.t.on are examined for sri Lanka using high-qualit. dat.set. for 19 met.orological st.t.ons, for a period bet.een 1980 and 2015. It.is evident.t.at.annually averaged mean minimum t.mperat.res are increasing across most.of sri Lanka. t.e difference bet.een maximum and minimum t.mperat.res, diurnal t.mperat.re range is decreasing, indicat.ng t.at.t.e minimum t.mperat.re is increasing fast.r t.an t.e maximum t.mperat.re. Significant.decrease in t.e annual occurrence of cold night. and increase in t.e annual occurrence of warm night. are also obvious. When compared wit. t.mperat.re changes, less spat.ally coherent.pat.ern of change and a lower level of st.t.st.cal significance were observed in precipit.t.on indices. t.e annual t.t.l precipit.t.on (PRCPt.t. has indicat.d a significant.increasing over 1980-2015. More t.an 80% of st.t.ons showed an increasing t.end in precipit.t.on indices. t.e t.ends in ext.eme precipit.t.on event. such as maximum one-day precipit.t.on, maximum five-day precipit.t.on, and t.t.l precipit.t.on on ext.eme rainfall days (R95p and R99p) are increasing at.most.locat.ons, indicat.ng t.at.t.e int.nsit. of t.e rainfall is increasing. Increase of precipit.t.on ext.eme t.ends indicat.s t.at.occurrence of ext.eme rainfall event. not.bly influences t.t.l annual precipit.t.on in sri Lanka. t.erefore, t.e observed increases in t.t.l rainfall observed in many locat.ons may be due in part.t. an increase in of ext.eme rainfall event.. Pat.erns of change in precipit.t.on ext.emes are more heavily influencing t.e climat. variabilit. by aggravat.ng t.e variabilit., significant.y influencing climat. sensit.ve sect.rs such as agricult.re and wat.r resource management.
