The contribution of areal precipitation of the catchment from Cuntan toYichang (Three Gorges area) to eight flood peaks of the Upper Yangtze River (the upper reaches ofthe Yangtze River) is diagnosed for 1998 flood season. A rainfall-runoff model is employed tosimulate runoffs of this catchment. Comparison of observed and simulated runoffs shows that therainfall-runoff model has a good capability to simulate the runoff over a large-scale river and theresults describe the eight flood peaks very well. Forecast results are closely associated with thesensitivity of the model to rainfall and the calibration processes. Other reasons leading tosimulation errors are further discussed.

Background： Combination of angiotensin-converting enzyme inhibitors and calcium channel blockers has been successfully used in the ant±hypertensive therapy for many years. Fixed dose combinations of ramipril/amlodipine have a benefit effect for patients to achieve target blood pressure （BP）. This study aimed to assess the efficacy and safety of fixed dose combinations oframipril and amlodipine （Egiramlon） in hypertensive diabetic patients. Methods： Hypertensive diabetic patients who were enrolled into the RAMONA trial were included in this open, prospective, Phase Ⅳ observational clinical study. Patients had mild-to-moderate hypertension and failed to reach target BP levels through their previous therapy. During the four months of observation, patients took part in three visits （1 st day - visit 1, 1 st month = visit 2, and 4th month = visit 3） where they received a fixed dose combination of 5/5, 5/10, 10/5, or 10/10 nag ramipril/amlodipine, respectively, with the possibly required dose titrations, based on the decision of their attending physician. Target BP for diabetic patients was 〈 140/85 mmHg. BP levels were measured in all visits, by taking two readings at 2-min interval. Laboratory tests including full blood count, renal function test, electrolytes, blood glucose, serum cholesterol, uric acid, triglycerides, liver function test, creatinine kinase, and midstream urinalysis were performed at visit 1 and visit 3. Results： The 6423 patients completed the study. Among these patients, 1276 （19.9%） patients suffered from type 2 diabetes mellitus. The mean age of these diabetic patients was 64.2 ±10.0 years; 707 （55.4%） patients were males. Target BP was achieved by 891 （69.8%） of diabetic patients at visit 3 （primary endpoint）. BP decreased from 157.5/91.3 ±9.6/7.6 mmHg （visit 1） to 130.9/79.6 ± 7.4/5.8 mmHg （visit 3）. As for the secondary endpoint of the study, total cholesterol decreased from 5.50 ±1.13 mmol/L （visit 1 ） to 5.20 ±0.95 mmol/L （P = 0.000）, low-dens

The prediction of chatter vibration is influencedby many known complex phenomena and is uncertain. Wepresent a new effect that can significantly change the sta-bility properties of cutting processes. It is shown that themicroscopic environment of chip formation can have alarge effect on its macroscopic properties. In this work, acombined model of the surface regeneration effect and chipformation is used to predict the stability of turning pro-cesses. In a chip segmentation sub-model, the primaryshear zone is described with a corresponding materialmodel along layers together with the thermodynamicbehavior. The surface regeneration is modeled by the time-delayed differential equation. Numerical simulations showthat the time scale of a chip segmentation model is sig-nificantly smaller than the time scale of the turning process;therefore, averaging methods can be used. Chip segmen-tation can decrease the average shear force leading todecreased cutting coefficients because of the non-lineareffects. A proper linearization of the equation of motionleads to an improved description of the cutting *** is shown that chip segmentation may significantlyincrease the stable domains in the stability charts; fur-thermore, by selecting proper parameters, unbounded sta-bility domains can be reached.

A field measurement campaign was carried out during the late winter and early spring of2015 in Budapest, the capital of Hungary. The size distribution(SD) and optical absorption of carbonaceous particulate matter(CPM) was measured online using a Scanning Mobility Particle Sizer(SMPS), a 7λ-aethalometer and an inhouse developed 4λ-Photoacoustic Spectrometer. Based on the SD data, the measurement period could be classified into days with and without new particle formation events(normal days and nucleation days),although particular nucleation-like events were observed on normal days as well. Three characteristic size modes were observed with CMDs of circa 15, 25 and 110 nm that corresponded to the nucleation, traffic and heating modes. Based on the temporal behavior of these modes both types of days were divided into distinctive daily periods(heating hours,traffic hours and nucleation hours). The optical absorption spectra(OAC and AAE) also displayed the same part of day behavior to that of SD. That way this paper is among the first to assess the optical response of urban nucleation events. Due to the simultaneous measurement of OAC by the 7λ-aethalometer and a 4λ-Photoacoustic Spectrometer, OAC was measured overall at 11 wavelengths. That way aethalometer correction factors(f and C)were determined at all aethalometer wavelengths using in situ reference photoacoustic measurements. Correction factors were found to have both wavelength and time of the day variation. In the case of f, no clear trend could be observed, however, Cref values increased both as a function of wavelength.

The density seasonal dynamics of Bemisia tabaci MED were evaluated over two years in a cotton-growing area in Langfang, Hebei Province, northern China on cotton （Gossypium hirsutum L.） and six other co-occurring common plants, common ragweed （Ambrosia artemisiifolia L.）, piemarker （Abutilon theophrasti Medicus）, sunflower （Helianthus annuus L.）, sweet potato （Ipomoea batatas L.）, soybean （Glycine max L.）, and maize （Zea mays L.）. The whitefly species identity was repeatedly tested and confirmed; seasonal dynamics on the various host plants were standardized by the quartile method. B. tabaci MED appeared on weeds （the common ragweed and piemarker） about 10 days earlier than on cotton, or the other cultivated plants. The peak population densities were observed over a span of 2 to 3 weeks on cotton, starting in early （2010） or mid-August （2011）. The common ragweed growing adjacent to cotton supported the highest B. tabaci densities （no. on 100 cm2 leaf surface）, 12-22 fold higher than on cotton itself. Sunflower supported more B. tabaci than the other plants, and about 1.5-2 fold higher than cotton did, Our results indicate that weeds （esp. the common ragweed） around cotton fields could increase the population density of B. tabaci MED on cotton, while sunflower could act as a trap crop for decreasing pest pressure on cotton.
