Searching for Minimum in Dependence of Squared Speed-of-Sound on Collision Energy by Fu-Hu Liu, Li-Na Gao, Roy A. Lacey

“…Experimental results of the rapidity distributions of negatively charged pions produced in proton-proton (p-p) and beryllium-beryllium (Be-Be) collisions at different beam momentums, measured by the NA61/SHINE Collaboration at the super proton synchrotron (SPS), are described by a revised (three-source) Landau hydrodynamic model. The squared speed-of-sound parameter cs2 is then extracted from the width of rapidity distribution. …”

Distribution of Pollutants in Nandu River Estuary in Different Environments by FANG Mingyi, SHI Haoran, HAILAI Yibo, LI Haisheng, MING Rui

“…In view of the frequent tropical storm surge in Nandu River Estuary in recent years,the increasing population in Haikou City each year,severe pollution emissions,and increasing upstream water use year by year,this paper studies the pollutant distribution in Nandu River Estuary under the storm surge and reduction of upstream water inflow on the basis of the hydrodynamic-water quality model.In addition,the changes of pollutants under different environments are analyzed.The results demonstrate that pollutants are mainly distributed on the left bank of the river and are mainly in striped shape due to the topography of the river.When the upstream flow is reduced by 20%,the effect of the tidal current is more significant,and pollutants are greatly affected by convection;the pollution zone becomes narrower,and the diffusion distance is the farthest.When the downstream tidal level is raised by 0.4 m,the interaction between the upstream inflow and tidal current is obvious;the flow rate decreases,and the pollutant retention is serious.In this case,pollutants mainly diffuse to the upstream by diffusion.Therefore,the upstream water resources should be effectively regulated and used,and the water surrounding the sewage outlet should be monitored with more efforts to provide a reference for the water environment management of the estuary section of Haikou City in the future.…”

Study on Modification Effects of Fish Passage Facilities in Angu Hydropower Station in Dadu River by ZHOU Wu, ZHANG Qi, SHI Jiayue, TANG Youmin, SUN Junjian

“…Due to the changed operating water level after the building of Angu Hydropower Station in Dadu River,the gate floors of the vertical slot fishway and nature-like passage are chiseled to lower the elevation and ensure water flow conditions.In order to understand the hydraulic condition of the modified fishway and the effect of fish passing,the water level and flow velocity in the fish passage facility are measured.The features of fishes in ecological river channels and fish passage facilities are investigated through net capturing.In addition,the operation status of fish passage facilities and the changes in aquatic ecological investigation results before and after modification are analyzed.The following main conclusions are drawn.After modification,the operation guarantee rate of fishway and passage is greatly improved,and the hydrodynamic conditions are close to the design effect; there are more fish species within the survey area after modification,and the species number of some migratory fishes has increased remarkably; there are obvious differences in fish species between vertical slot fishway and nature-like passage of ecological river sluice in Angu Hydropower Station,and the two channels are suitable for different fish species,showing a complementary effect.…”

Observation of Gaussian Pseudorapidity Distributions for Produced Particles in Proton-Nucleus Collisions at Tevatron Energies by Abdurakhmanov Ulugbek, Gulamov Kadyr, Lugovoi Vladimir, Navotny Vadim

“…The statistical event-by-event analysis of inelastic interactions of protons in emulsion at 800 GeV reveals the existence of group of events with Gaussian pseudorapidity distributions for produced particles, as suggested by hydrodynamic-tube model. Events belong to very central collisions of protons with heavy emulsion nuclei with probability of realization of less than 1% and with multiplicity of shower particles exceeding (2-3 times) the average multiplicity in proton-nucleus collisions in emulsion. …”

Investigation of motion response suppression characteristics in floating platforms equipped with novel spiral side plates by Yu Jing‐mei, Bai Chun‐long

“…The results indicate that in the frequency domain analysis, the platform with serrated helical side plates demonstrates reduced sensitivity to waves, with a particularly notable increase in added mass in the heave direction, suggesting excellent hydrodynamic performance. In the time domain analysis, improvements in the platform's surge and heave stability performances were observed, measuring 10.99% and 10.64%, respectively, in extreme conditions. …”
