A series of tests were conducted in a South African concentrator on the secondary grinding mill. The results were analysed and provided showed the importance of selecting an optimum density and filling degree of the mill. Moreover, a Sensomag (r) is installed on this mill and the surveys showed that an increase of the density was improving the mixing of balls in the pulp and increasing the grinding performance.

The familiar multivariate process monitoring and control procedure is the Hotelling’s T2 control chart, a direct analog of the univariate shewhart chart. But, its efficiency for detecting small to moderate shifts in the process mean is poor. To improve the power of chart, this paper presents the variable sampling intervals (VSI) scheme. It is assumed that the length of time the process remains in control has exponential distribution. The chart is modeled using Markov chains and is optimized using genetic algorithm optimization method. The results show that the T2 chart with variable ratio sampling scheme is quicker than the classical one in detecting almost all shifts in the process mean [less ▲]

The proposed concept consists in placing a steel profile with limited size inside the reinforced concrete column of the first level of the building. This profile is not considered for the design and is essen-tially assumed to act as a safety belt activated only in case of deficiencies of the concrete under earthquake action, providing thus the requested robustness and limiting the risk of soft-storey mechanisms even in the most unfavorable conditions. Theoretical, experimental and numerical investigations summarized in the pre-sent contribution are aiming at demonstrating the efficiency of the concept. [less ▲]

This letter proposes a formulation of the corrective security-constrained optimal power-flow problem imposing, in addition to the classical post-contingency constraints, existence and viability constraints on the short-term equilibrium reached just after contingency. The rationale for doing so is discussed and supported by two examples. [less ▲]

Using a full scale anesthesia simulator, we compare and analyze the responses of anesthesia trainees (second and third year trainees and fourth and fifth year trainees) to 4 simulated problem situations that are very close to a real-world situation in order to establish relationship between these analyses and the contents of medical training cursus. Data were collected from systematic observations and videotaping of simulation sessions and self-confrontation. Several quantitative and qualitative variables were used to compare the performance of subjects: accuracy and speed of diagnosis, type of behaviors, identification and selectivity of diagnostic indices, hypotheses generated, type of reasoning.

L'impuissance érectile est souvent considérée comme un symptôme simple et banal. Pourtant, il apparaît très vite que la plus grande incertitude plane sur la nature et l'efficacité des facteurs étiologiques supposés. La méconnaissance de certains facteurs, leur multiplicité, les interactions complexes qui les unissent, l'aspécificité du symptôme ne permettent guère d'aboutir à une conviction raisonnable. Ce problème se pose également sur le plan organique et sur le plan psychique. En fait, il semblerait que chacune des diverses théories explicatives soit adéquate dans des cas particuliers mais qu'aucune ne soit généralisable, contrairement à ce que beaucoup d'auteurs et praticiens font.

This study reports on 100 cases of males, aged 21 to 63 years, consulting for difficulties or inability to perform an intercourse erection with a partner of their choice. Every patient was investigated by the same psychiatrist the same psychologist and the same endocrinologist. Testosterone blood level was found insufficient (2 sigma under the mean) in 48 cases. The psychological tests emphasized an important but clinically inconspicuous psychopathology. Anxious and depressive trends were very frequent. The result of the investigations oriented the treatment, which used several methods, single or in association : brief psychotherapy, nasal stress, hormones, psychotropic drugs. After one year of follow-up, 67 men were improved or recovered and 22 unchanged. [less ▲]
