Introduc.ion: Primary polydipsia, frequently observed in patients with sc.izophrenia, c.n c.use severe hyponatremia, leading to serious c.mplic.tions. Objec.ive: this study reviews the management and prevalenc. of psyc.ogenic.polydipsia, foc.sing on treatments and c.inic.l outc.mes. Methods: Following the PRISMA guidelines, studies on polydipsia in psyc.iatric.patients were inc.uded. Data were extrac.ed from databases suc. as PubMed and Sc.pus, and a meta-analysis was performed. Results: Fifteen studies were analyzed, totaling 586 patients. the use of urea was effec.ive in c.rrec.ing hyponatremia, while antipsyc.otic. showed mixed results. Heterogeneity between studies was moderate (I2 = 56%). c.nc.usion: Psyc.ogenic.polydipsia is a severe c.ndition in sc.izophrenic.patients. the use of urea has shown promise, but further studies are needed to optimize treatments.

this paper uses a finite dominating set （FDS） to investigate the multi-fac.lity ordered median problem （OMP） in a strongly c.nnec.ed direc.ed network. the authors first prove that the multi-fac.lity OMP has an FDS in the node set, whic. not only generalizes the FDS result provided by Kalc.ic., et al. （2002）, but also extends the FDS result from the single-fac.lity c.se to the multiple c.se, filling an important gap. then, based on this FDS result, the authors develop an exac. algorithm to solve the problem. However, if the number of fac.lities is large, it is not prac.ic.l to find the optimal solution, bec.use the multi-fac.lity OMP in direc.ed networks is NP-hard. Henc., we present a c.nstant-approximation algorithm for the p-median problem in direc.ed networks. Finally, we pose an open problem for future researc..

Mixed ammonium-transition metal salts with formula of （NH4）xMyHzPMo12O40 （M = Ni^2＋, c.^2＋ or Fe ^3＋） denoted as MPMo12 have been investigated for the oxidation of propane, with molec.lar oxygen, at temperature range between 380 ℃ and 420 ℃ after in-situ pre-treatment performed at two heating rate of 5 or 9℃/min. they were c.arac.erized by BEt method, XRD, UV-Vis and IR tec.niques. the c.talysts were found to be ac.ive in the propane oxidation and selec.ive to propene or ac.olein, in partic.lar for samples pre-treated with the heating rate of 9℃/min. FePMo12 was found to be a more ac.ive c.talyst for propene （17.2% yield） with minimal over deep oxidation （0.3% yield in c.x）.

Peri-annulation is rec.gnized as an influential struc.ural motif in ac.essing func.ional molec.lar materials. However, effic.ent synthetic.ac.ess to peri-annulated struc.ures remains c.allenging. Herein, we show that mec.anoc.emistry is a valuable synthetic.tool to ac.ieve this goal. It is c.mparatively better than ac.ivation through mic.owave irradiation and c.nventional solution-phase reac.ions. the synthesized materials are molec.larly c.rved nanographenes c.ntaining sulfur and selenium atoms. the c.rvature c.mes from the use of c.rannulene as the c.ntral building bloc., upon whic. the benzothiophene or benzoselenophene are peri-annulated through the palladium-c.talyzed direc. arylation reac.ions. Peri-annulation endows the nanographene struc.ures with better optic.l properties as c.mpared to other annulation c.emistries.

the ongoing need to deliver improved safety, produc.ivity and environmental benefit in c.al mining presents an open c.allenge as well as a powerful inc.ntive to develop new and improved solutions. this paper assesses the c.itic.l role that enabling tec.nologies have played in the delivery of remote and automated c.pability for longwall mining. A brief historic.l ac.ount is given to highlight key tec.nic.l c.ntributions whic. have influenc.d the direc.ion and development of present-day longwall tec.nology. the c.rrent state of longwall automation is disc.ssed with partic.lar attention drawn to the tec.nologies that enable automated c.pability. Outc.mes are presented from an independently c.nduc.ed c.se study that assessed the impac. that c.IRO＇s LASc.longwall automation researc. has made to the longwall mining industry in Australia. Importantly, this study reveals how uptake of this innova- tive tec.nology has signific.ntly benefitted c.al mine produc.ivity, improved working c.nditions for personnel and enhanc.d environmental outc.mes. these benefits have been widely adopted with c.IRO automation tec.nology being used in 60 per c.nt of all Australian underground operations. International deployment of the tec.nology is also emerging. the paper c.nc.udes with future c.allenges and opportunities to highfight the ongoing sc.pe for longwall automation researc. and development.

A c.ntac.or vessel was built to operate as either a mec.anic.lly or a c.nventional spouted bed for the purpose of analyzing the drying of pasty and granular materials under c.mparable c.nditions in both c.nfigurations. A c.assic.l c.nic.l–c.lindric.l spouted bed with a 60° c.nic.l base and an air inlet c.ntral orific. was modified to enable the switc. by introduc.ng in the vessel’s c.nter an open helic.idal c.nveyor sc.ew plac.d above the air inlet orific.. this sc.ew is removable and c.nveniently returns the bed to its c.nventional spouted c.nfiguration. Experiments on drying solutions (c.lc.um c.rbonate suspensions and skimmed milk) and granular materials (porous alumina partic.es) were performed for various bed parameter settings. the spouting pressure drop, outlet air temperature, and relative humidity were measured over time under different c.nditions. Mec.anic.l agitation is proved effec.ive in drying diluted c.rbonate c.lc.um liquid suspensions and c.arse porous alumina partic.es at an air veloc.ty approximately 50% lower in c.mparison to drying in a c.nventional spouted bed. the c.nventional spouted bed performed better at drying liquid skimmed milk as the mec.anic.l agitation c.mbined with the axial inlet air flow is not effec.ive in mitigating stic.ing and powder agglomeration in the bed when handling pastes of c.mplex c.mposition. Introduc.ng mec.anic.l agitation in the designed setup broadens the operating range of a c.nventional spouted bed with axial air flow in the inlet.

天雨如注，开车的感觉犹如穿越厚厚的水幕。他稍稍松开油门。夜色深沉，又逢风狂雨骤，务必要当心，千万别发生事故，车别出故障。暴风雨之夜，人只想窝在家里。雨刮器“刺啦刺啦”地反复摩擦挡风玻璃，令人昏昏欲睡。他透过前灯微弱的光晕凝视前方。雨打汽车，听起来犹如白噪声，不由得使他想起希区柯克电影开篇的场景。透过瓢泼暴雨，他注意到路边有人影晃动。
