Between June 2005 and February 2006, focal sampling and all occurrence behavior recording were used to quantify the behavioral patterns of captive female alpine musk deer （Moschus sifanicus） at Xinglongshan Musk Deer Farm, Gansu Province, China. Copulation success was used to differentiate individuals into two groups （successful and unsuccessful） and to provide a basis for behavioral comparisons, throughout both mating （rut） and non mating seasons. The results indicated significant differences between the behavior patterns of successful and unsuccessful females; however, the reproductive season played an important environmental factor. Pooling results across reproductive seasons, successfully copulating females showed significantly higher frequencies of vigilance and lower frequency of feeding behavior as compared with unsuccessfully copulating females. In the non-mating season, unsuccessfully copulating females had higher frequency of self-directed behavior, environment sniffing, and were less aggressive than successful copulating females. Furthermore, females who were successful at copulating also demonstrated tail-pasting behavior; however, this only occurred during the rut season. The results of this study can improve management practices for musk deer farms through increasing mating success and reducing maintenance costs. Furthermore, variation in behavior may also be used as a predictor of copulation success and reproductive potential, whereby females can be grouped and separated according to their reproductive history and past reproduction success.

BACKGROUND: Liver transplantation is one of the most effective therapeutic options for patients with end-stage liver diseases, and gut microbiota is actively involved in potential infections in pretransplant and posttransplant patients. However, the diversity of gut microbiota and its relationship with the immune parameter of liver transplantation recipients are not well understood. METHODS: We collected fresh feces and blood samples from 190 participants in China from November 2004 to May 2008, including 28 healthy volunteers, 51 cirrhotic patients and 111 liver-transplanted patients. Six interesting gut bacteria, plasma endotoxin, serum cytokines (i.e., tumor necrosis factor alpha and interleukin-6) and fecal secretory IgA (SIgA) were investigated by real-time quantitative PCR, chromogenic limulus amoebocyte assay, sandwich-type enzyme-linked immunosorbent assay and radioimmunoassay, respectively. RESULTS: All Eubacteria, Bifidobacterium spp., Faecalibacterium prausnitzii and Lactobacillus spp. were significantly lower in the liver transplantation recipients while Enterobacteriaceae and Enterococcus spp. were significantly higher (P<0.05). Except for Enterococcus spp., other bacteria showed a tendency to restore to normal level along with the time after liver transplantation. Plasma endotoxin, interleukin-6 and fecal SIgA in cirrhotic patients increased significantly, but not in liver transplantation recipients. Plasma endotoxin and interleukin-6 were negatively correlated with all Eubacteria and the Bacteroides-Prevotella group, while tumor necrosis factor alpha was not significantly correlated with these six gut bacteria in cirrhotic ***: Our study demonstrates that abundant gut bacteria were altered significantly in both cirrhotic and liver transplantation patients, while plasma endotoxin and interleukin-6 increased remarkably in cirrhotic patients, showing significant correlations with gut microbiota. Interestingly, our data show a tendency fo

Under submerged conditions, compared with traditional self-excited oscillating pulsed waterjets(SOPWs), annular fluid-enhanced self-excited oscillating pulsed waterjets(AFESOPWs) exhibit a higher surge pressure through self-priming. However, their pressure frequency and cavitation characteristics remain unclear, resulting in an inability to fully utilize resonance and cavitation erosion to break coal and rock. In this study, high-frequency pressure testing, high-speed photography, and large eddy simulation(LES) are used to investigate the distribution of the pressure frequency band, evolution law of the cavitation cloud, and its regulation mechanism of a continuous waterjet, SOPW, and AFESOPW. The results indicated that the excitation of the plunger pump, shearing layer vortex, and bubble collapse corresponded to the three high-amplitude frequency bands of the waterjet pressure. AFESOPWs have an additional self-priming frequency that can produce a larger amplitude under a synergistic effect with the second high-amplitude frequency band. A better cavitation effect was produced after self-priming the annulus fluid, and the shedding frequency of the cavitation clouds of the three types of waterjets was linearly related to the cavitation number. The peak pressure of the waterjet and cavitation erosion effect can be improved by modulating the waterjet pressure oscillation frequency and cavitation shedding frequency.

在冕宁县冶勒自然保护区设点 ,从种群水平对同域分布、以同种竹子为食的大熊猫和小熊猫种群能流进行了研究。结果表明 :通过大熊猫种群的能流 ( 1 86× 1 0 6kJ/km2 .yr.)多于小熊猫种群 ( 6 34× 1 0 5kJ/km2 .yr.) ,前者大约是后者的 2 9倍 ,说明大熊猫在群落中可能处于优势地位。虽然两种熊猫可利用食物资源占地面生物量的比例很小 (大、小熊猫分别为 1 2 79%和 3 92 % ) ,但是其每年摄入的能量和通过种群的能流仅占食物资源现存生物量或可利用生物量的百万分之几到万分之几。因此 ,研究区域内两种熊猫的食物资源十分丰富 ,若竹子不大面积开花枯死 ,食物资源将不会成为其种群发展的限制因子。
