First measurement of neutrino and antineutrino coherent charged pion production on argon.

We report on the first cross section measurements for charged current coherent pion production by neutrinos and antineutrinos on argon. These measurements are performed using the ArgoNeuT detector exposed to the NuMI beam at Fermilab. The cross sections are measured to be 2.

First measurements of inclusive muon neutrino charged current differential cross sections on argon.

The ArgoNeuT Collaboration presents the first measurements of inclusive muon neutrino charged current differential cross sections on argon. Obtained in the NuMI neutrino beam line at Fermilab, the flux-integrated results are reported in terms of outgoing muon angle and momentum. The data are consistent with the Monte Carlo expectation across the full range of kinematics sampled, 0°<θ(μ)<36° and 0 View Article and Find Full Text PDF

Odour removal with a trickling filter at a small WWTP strongly influenced by the tourism season.

Etaples-Le Touquet's wastewater treatment plant (WWTP) is based on a coastal area of the Artois-Picardie region. The pollution load can vary from 20,000 p.e.

[Anatomic study of the right ventricular inferior wall. Search for the optimal site for implanting epicardial pacing electrodes].

The inferior wall of the right ventricle was studied to determine the optimal site of implantation of epicardial pacing electrodes. The hearts of 10 patients without cardiac disease, aged 57 to 84 years, who died in Broussais hospital, were studied. The hearts were washed, weighed (300 to 550 g) and placed in a formol solution to which was added half its volume of Larsen's solution.

Suppression of renin secretion by insulin: dependence on extracellular calcium.

The isolated perfused rat kidney was used to examine the effect of insulin on renin release (RR). Insulin produced a dose-dependent reduction of RR when added to the perfusate at concentrations between 10 and 1,000 microU/ml. When kidneys were perfused with a calcium-free perfusate, RR increased nearly fivefold.

[Severe postoperative heart blocks appearing late. 16 cases].

Sixteen patients, aged 4 to 42 years, operated for congenital heart disease, presented, months or years after surgery, complete atrioventricular (11 cases) or sinoatrial block (5 cases). Six patients had transient complete atrioventricular block in the immediate postoperative period, the maximum duration of which was less than 30 days. The late postoperative period was defined as at least 6 months after surgery.

[Incidence of hyperuricemia in atrioventricular block. Systematic study of 158 cases which required implantation of an isotopic cardiac pacemaker].

This is a study of 158 patients in whom the placement of an isotopic cardiac pacemaker was indicated; this procedure was carried out Broussais Hospital between 1970 and 1975. These patients, whose mean age was 39 (84 males, 47 females, 12 young men and 15 young women) were examined for uricaemia, and the levels compared with the mean for control population. The results were as follows: 91% had uricaemia at a level higher than the controls.

[Isotop cardiac pacemaker during pregnancy. 3 cases].

The authors report three cases of full term pregnancies, without complications, in women with isotopic pacemakers. The newborn infants were normal. In one case, pregnancy occurred in a patient who already had a pacemaker.

[Occurrence of hyperuricemia in atrioventricular block. (Results of a study of 158 patients with isotopic pacemaker implantations)].

The frequency of hyperuricemia is high in these patients with heart block, whose mean age is 39. 91% have serum uric acid levels above the normal range and 61% present "hyperuricemia," according to "gouty risk" criteria. The mean uric acid level, before surgery, of the patients whose total heart block follows "open-heart" is the highest in our statistics.

[Long-term survival in persons with cardiac pacemakers. Study based on 1,159 patients, 499 with regression at 4-10 years].

Analysis of the long-term survival of pacemaker carriers showed a parallelism between two curves: that of the survival in patients treated with a pacemaker as from the second month, and that of a control group with the same age and physical structure. Treatment in the first few years was made problematical by defects in surgical technique: while in 17% of reoperations, the reason was straightforward substitution of the pacemaker owing to wear on the battery, 83% were the consequences of complications. Of these, 23% consisted of shifts in the intracavitary probe, electrode failures, or increase in the threshold.

[Survival time of patients with cardiac pacemakers (author's transl)].

A comparison between the life expectancy of patients with pacemakers and that of a control population of similar structure shows a parallel course, although originally, after a postoperative phase of 2 months, the mortality rate of the patients with pacemakers was higher. Today the results are considerably better. Implantation of pacemakers is one of the greatest cardiological advances in the last 10 years for the effective treatment and prevention of cardiac arrest in atrioventricular block.
