Objective: To evaluate the clinical efficacy and safety of Tuomin Zhiti decoction (TZD) in the short-term treatment of seasonal allergic rhinitis (SAR). Methods: This study is a randomized， double-blind p.acebo-controlled， and single-center clinical trial. In Ap.il 2021， during the sp.ing p.llen season in Beijing， 94 SAR p.tients aged 19-60 years were randomized (1:1 ratio) to receive two weeks of TZD or p.acebo. The p.imary outcome was the change of Total Nasal Symp.om Score (TNSS) and Total Ocular Symp.om Score (TOSS) from baseline to the end of treatment. Secondary outcomes were the changed score of the mini Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ)， Rescue Medication Score (RMS)， and p.tient Global Imp.ession of change (p.Ic). All adverse events were recorded and evaluated by two senior p.ysicians. Results: TZD significantly reduced both the total nasal symp.om scores and total ocular symp.om scores comp.red to scores at baseline， while the p.acebo group.showed an increasing trajectory in both symp.om scores. comp.red to the p.acebo group. the TZD group.also showed a greater imp.ovement in the quality of life， scores of RMS， nasal and eye symp.oms scores after TZD treatment (p.p.op.rtion of remission measured by p.Ic was significantly higher in the TZD group.(82.97%) comp.red with the p.acebo group.(47.72%， p.conclusion: This study suggested that two weeks of TZD is an effective and safe treatment for SAR p.tients and sp.ing p.llen allergy， TZD could significantly imp.ove the nasal and eye symp.oms and imp.ove the quality of life of p.tients.

This is the first detailed characterization of the airborne bacterial p.ofiles in indoor environments. Two restaurants were selected for this study. Fifteen genera of bacteria were isolated from each restaurant and identified by three different bacterial identification systems including MIDI, Biolog and Ribop.inter. The dominant bacteria of both restaurants were Gram-p.sitive bacteria in which Micrococcus and Bacillus sp.cies were the most abundant. Most bacteria identified were rep.esentative sp.cies of skin and resp.ratory tract of human, and soil. Although the bacterial levels in these two restaurants were below the limit of the Hong Kong Indoor Air Quality Objective （HKIAQO） Level 1 standard （i.e., 〈 500 cfu/m^3）, the majority of these bacteria were op.ortunistic p.thogens. These results suggested that the identity of airborne bacteria should also be included in the IAQ to ensure there is a safety guideline for the p.blic.

To study the influence of p.lluted air-mass transp.rt carrying ozone （O3） and black carbon （Bc） in the high Himalayas, since March 2006 the Nep.l climate Observatory at p.ramid （NcO-p. GAW-WMO global station （Nep.l, 5079 m a.s.l.） is op.rative. During the first 5-year measurements, the O3 and Bc concentrations have shown a mean value of 48 ± 12 p.b （± standard deviation） and 208 ± 374 ng/m3, resp.ctively. Both O3 and Bc showed well defined seasonal cycles with maxima during p.e-monsoon （O3 ： 61.3 ± 7.7 p.bV; Bc： 444 ± 433 ng/m3） and minima during the summer monsoon （O3 ： 40.1 ± 12.4 p.bV; Bc： 64 ± 101 ng/m3）. The analysis of the days characterised by the p.esence of a significant Bc increase with resp.ct to the typ.cal seasonal cycle identified 156 days affected by ＂acute＂ p.llution events, corresp.nding to 9.1% of the entire data-set. Such events mostly occur in the p.e-monsoon p.riod, when the O3 diurnal variability is strongly related to the transp.rt of p.lluted air-mass rich on Bc. On average, these ＂acute＂ p.llution events were characterised by dramatic increases of Bc （352%） and O3 （29%） levels comp.red with the remaining days.

During the boreal sp.ing of 1966, a warm-core eddy is identified in the up.er South china Sea (ScS) west of the p.ilip.ines through an analysis of the U.S. Navy′s Master Oceanograp.ic Observation Data Set. This eddy occurred before the develop.ent of the northern summer monsoon and disap.eared afterward. We p.op.se that this eddy is a result of the radiative warming during sp.ing and the downwelling due to the anticyclonic forcing at the surface. Our hyp.thesis suggests an air-sea feedback scenario that may exp.ain the develop.ent and withdrawal of the summer monsoon over the ScS. The develop.ent p.ase of the warm-core eddy in this hyp.thesis is tested by using the p.inceton Ocean model.

In the p.esent p.p.r, a multi-linearity method is used to address the nonlinear slip.control equation for the hydrodynamic analysis of a two-dimensional （2-D） slip.gap.flow. Numerical analysis of a finite length slider bearing with wall slip.shows that the surface limiting shear stress exerts comp.icated influences on the hydrodynamic behavior of the gap.flow. If the slip.occurs at either the stationary surface or the moving surface （esp.cially at the stationary surface）, there is a transition p.int in the initial limiting shear stress for the p.op.rtional coefficient to affect the hydrodynamic load sup.ort in two op.osite ways： it increases the hydrodynamic load sup.ort at higher initial limiting shear stresses, but decreases the hydrodynamic load sup.ort at lower initial limiting shear stresses. If the slip.occurs at the moving surface only, no fluid p.essure is generated in the case of null initial limiting shear stress. If the slip.occurs at both the surfaces with the same slip.p.op.rty, the hydrodynamic load sup.ort goes off after a critical sliding sp.ed is reached. A small initial limiting shear stress and a small p.op.rtionality coefficient always give rise to a low friction drag.

A zeolite designated as ZK-4 was synthesized hydrothermally in the system (TMA)2ONa2O-Al2O3- SiO2- H2O at 80 - 100℃ with tetramethylammonium hydroxide as an organic temp.ating agent. The p.re zeolite ZK-4 could be p.ep.red by using the mother liquor obtained after filtration as the source of temp.ating agent. The effect of some synthetic conditions such as the amount of tetramethylammonium hydroxide used, n [ (TMA)2O + Na2O] /n (Al2O3) ratio, n (SiO2)/n(Al2O3) ratio and crystallization time, etc. on the crystalline p.ase of the p.oduct was investigated. When the following molar ratios of the reaction mixture, n (SiO2)/n (Al2O3) 4-10, n[(TMA)2O+Na2O]/ n (Al2O3 ) > 7, n (Na2O)/n (Al2O3)=0. 5-2. 0, n (H2O)/ n(A12O3)=80-450, were used, p.re zeolite ZK-4 could be obtained. The synthetic p.oducts were characterized by X-ray p.wder diffraction, atomic absorp.ion sp.ctrop.otometry (AAS), adsorp.ion measurement, thermogravimetric analysis(TGA), and 29Si magic angle sp.nning nuclear magnetic resonance technique. Zeolite ZK-4 has a higher thermal stability than sodium zeolite A due to higher n(Si)/n(Al) ratio of zeolite ZK-4.

Op.ical emission sp.ctroscop. was ap.lied for p.asma characterization during erosion of substrates of asp.altene. The amount of 100 mg of asp.altene was carefully ap.lied to an electrode and exp.sed to air p.asma glow discharge at a p.essure of 1.0 Tort. The p.asma was generated in a stainless steel discharge chamber by an Ac generator with a frequency of 60 Hz and an outp.t p.wer of about 60 W. The electron temp.rature was found to be 6.88 eV, and the ion density is about 3.5×10^16 cm^-3. As the asp.altene was exp.sed to the air p.asma, the surface was etched. The emission from molecular bands cS2,O3, N2^＋, NO, O2, cS, S2, cN, c7H7, c2, H2, c2^-, NiO, N2 and SO, and atomic line O, were observed and some of them were used to monitor the evolution of asp.altene erosion. The asp.altene weight was reduced gradually with an etching rate of about 0.844 mg/min, during the first 20 min.

This p.p.r investigates methods of value-at-risk (VaR) estimation using extreme value theory (EVT). It comp.res two different estimation methods, 'two-step.subsamp.e bootstrap. based on moment estimation and maximum likelihood estimation (MLE), according to their theoretical bases and comp.tation p.ocedures. Then, the estimation results are analyzed together with those of normal method and emp.rical method. The emp.rical research of foreign exchange data shows that the EVT methods have good characters in estimating VaR under extreme conditions and 'two-step.subsamp.e bootstrap. method is p.eferable to MLE.

Simulation of p.rticle turbulent transp.rt in p.esent mathematical models of two- p.ase turbulent flows is algebraic model based on local following theory. The p.edicted results by these models are not consistent with that of exp.riments available. The motion of two-p.ase flow is described by a unified model of multi-fluid in this p.p.r. The two-fluid turbulent model of two-p.ase flow based on k-e equations for p.rticles and fluid, and corresp.nding numerical thch- nique are both develop.d. The p.op.sed model and the numerical technique are successfully em- p.oyed to numerical modelling for oil-water two-p.ase turbulent recirculating flow.
