Modeling the Enceladus plume--plasma interaction

We investigate the chemical interaction between Saturn's corotating plasma and Enceladus' volcanic plumes. We evolve plasma as it passes through a prescribed H2O plume using a physical chemistry model adapted for water-group reactions. The flow field is assumed to be that of a plasma around an electrically-conducting obstacle centered on Enceladus and aligned with Saturn's magnetic field, consistent with Cassini magnetometer data. We explore the effects on the physical chemistry due to: (1) a small population of hot electrons; (2) a plasma flow decelerated in response to the pickup of fresh ions; (3) the source rate of neutral H2O. The model confirms that charge exchange dominates the local chemistry and that H3O+ dominates the water-group composition downstream of the Enceladus plumes. We also find that the amount of fresh pickup ions depends heavily on both the neutral source strength and on the presence of a persistent population of hot electrons.Comment: 10 pages, 1 table, 2 figure

A possible nature of breathing plasmas

A model for "breathing" plasmas observed in the large helical device [Y. Takeiri , Plasma Phys. Controlled Fusion 42, 147 (2000)] is proposed. It takes into account the synergism of radiation losses from both low-Z (carbon, oxygen) and high-Z (iron) impurities in the plasma power balance. (C) 2000 American Institute of Physics.

Ureteroscopic lithotripsy for ureteral stones in children using holmium: yag laser energy: results of a multicentric survey

BACKGROUND: Holmium:YAG (Ho:YAG) laser lithotripsy has broadened the indications for ureteroscopic stone managements in adults, but few evidence are currently available in the pediatric population. OBJECTIVE: This article aimed to assess the outcome of Ho:YAG laser lithotripsy during retrograde ureteroscopic management of ureteral stones in different locations in children. STUDY DESIGN: The medical records of 149 patients (71 boys and 78 girls; median age 9.2 years) treated with Ho:YAG laser ureteroscopic lithotripsy in five international pediatric urology units over the last 5 years were retrospectively reviewed. Exclusion criteria included patients with renal calculi and/or with a history of ipsilateral stricture, renal failure, active urinary tract infection, or coagulation disorder. RESULTS: Stones were treated with dusting technique in all cases. The median stone size was 10.3 mm (range 5-17). Stones were located in the distal ureter in 77 cases (51.7%), in the middle ureter in 23 cases (15.4%), and in the proximal ureter in 49 cases (32.9%). The median operative time was 29.8 min (range 20-95). Intra-operative complications included five bleedings (3.3%) and seven stone retropulsions (4.7%). Overall stone-free rate was 97.3%. Overall postoperative complications rate was 4.0% and included two cases of stent migration (1.3%) (Clavien II) and four residual stone fragments (2.7%) that were successfully treated using the same technique (Clavien IIIb). On multivariate analysis, re-operation rate was significantly dependent on the proximal stone location and presence of residual fragments >2 mm (P = 0.001). DISCUSSION: This study is one of the largest pediatric series among those published until now. The study series reported a shorter operative time, a higher success rate, and a lower postoperative complications rate compared with previous series. A limitation of this study is that stone-free rates may be somewhat inaccurate using ultrasonography and plain X-ray compared with computed tomography (CT); the study's 97.3% success rate may be overestimated because no CT scan was done postoperatively to check the stone-free rate. Other limitations of this article include its retrospective nature, the multi-institutional participation, and the heterogeneous patient collective. CONCLUSION: The Ho:YAG laser ureteroscopic lithotripsy seems to be an excellent first-line treatment for children with ureteral stones, independently from primary location and size. However, patients with proximal ureteral stones and residual fragments >2 mm reported a higher risk to require a secondary procedure to become stone-free. Combination of techniques as well as appropriate endourologic tools are key points for the success of the procedure regardless of stones' size and location

The state of the system of antioxidant protection of the body of dogs during toxocariasis invasion

Among the invasive diseases of dogs, the most common in our country and abroad is gastrointestinal helminthiasis, among which the leading place is occupied by toxocarosis. Adult toxocara cause an intestinal form of the disease, and the larvae – a visceral one. In the process of migration and vital activity, toxocar larvae cause severe damage to the body of dogs up to death. The work aimed to determine the effect of toxocariasis on the enzymatic and non-enzymatic links of the system of antioxidant protection of the dog's body. Twelve two- to four-month-old dogs were used for experimental research, and two groups of six animals each were formed: control and experimental. Puppies of the control group were clinically healthy. Puppies of the experimental group were experimentally infected with the causative agent of toxocarosis at a dose of 5,000 invasive T. canis eggs per kg of body weight. It was established that the antioxidant protection system of the dog's body is inhibited during toxocariasis infection, which is indicated by a decrease in the activity of the enzyme link and indicators of the glutathione system. Under the conditions of experimental toxocarosis invasion, a decrease in the activity of the enzyme link of the system of antioxidant protection of the dog's body was established, as indicated by a reduction in the activity of catalase by 51.9 %, superoxide dismutase by 33.4 %. The development of toxocariasis in dogs is also accompanied by depletion of the glutathione-dependent link of the antioxidant defense system. In infected dogs, a decrease in the content of reduced glutathione in their blood was established by 31.1 % (Р < 0.01), glutathione peroxidase activity – by 26.6 % (Р < 0.001), glutathione reductase activity – by 22.2 % (Р < 0.001). The lowest activity of enzymes of the antioxidant system and the content of reduced glutathione in the blood of infected dogs of the experimental group was established on the 28th day of the experiment

Theory of temperature dependence of the Fermi surface-induced splitting of the alloy diffuse-scattering intensity peak

The explanation is presented for the temperature dependence of the fourfold intensity peak splitting found recently in diffuse scattering from the disordered Cu3Au alloy. The wavevector and temperature dependence of the self-energy is identified as the origin of the observed behaviour. Two approaches for the calculation of the self-energy, the high-temperature expansion and the alpha-expansion, are proposed. Applied to the Cu3Au alloy, both methods predict the increase of the splitting with temperature, in agreement with the experimental results.Comment: 4 pages, 3 EPS figures, RevTeX, submitted to J.
