Tb-140 and Dy-141 were produced via fusion evaporation in the reaction Ca-40+Cd-106. Their beta-delayed proton decays were studied by means of "p-gamma" coincidence in combination with a He-jet tape transport system, including half-lives, proton energy spectra, gamma-transitions following the proton emissions, and the branching ratios to the low-lying states in the grand-daughter nuclei. The ground-state spins and parities of Tb-140 and Dy-141 were extracted as 7(+/-) and 9/2(+/-), respectively, by fitting the experimental data with a statistical model calculation. The configuration-constrained nuclear potential energy surfaces (NPES) of Tb-140 and Dy-141 were calculated by using the Woods-Saxon Strutinsky method, which indicate the ground-state spins and parities of Tb-140 and Dy-147 to be 7(+) and 9/2(-), respectively. In addition, the configuration-constrained NPES of Dy-143 was also calculated by using the same method. From the NPES a 1/2(+) ground state and a 11/2(-) isomer with the excitation energy of 198keV were found. The calculated results are consistent with our experimental data on the decay of Dy-143 reported in Eur. Phys. J., 2003, A16: 347-351.

The proton-rich isotopes Tb-140 and Dy-141 were produced via the fusion evaporation reaction Ca-40+ Cd-106. Their beta-delayed proton decays were studied by p-gamma coincidence in combination with a He-jet tape transport system, and half-lives, proton energy spectra, gamma-transitions following the proton emission, as well as beta-delayed proton branching ratios to the low-lying states in the grand-daughter nuclei were determined. Comparing the experimental data with statistical model calculations, the ground-state spins of Tb-140 and Dy-141 were found to be consistent with 7 and 9/2, respectively. The configuration-constrained nuclear potential energy surfaces (NPES) of Tb-140 and Dy-141 were calculated using the Woods-Saxon-Strutinsky method, which suggest the ground-state spins and parities of Tb-140 and Dy-141 to be 7(+) and 9/2(-), respectively. In addition, the configuration-constrained NPES of Dy-143 were calculated, which predict a 1/2(+) ground state and a 11/2(-) isomer with excitation energy of 198 keV. These findings are consistent with our previous experimental data on Dy-143 reported in Eur. Phys. J. A 16, 347 (2003).

The prevalence of undernutrition was prospectively studied in 143 patients before liver transplantation between 1997 and 2005. Nutritional assessment is a particularly tricky problem in cirrhosis and mid-arm muscle circumference is considered as the best reliable anthropometric tool. In this prospective study, prevalence rate is very high (61%) and undernutrition is more frequent in alcoholic cirrhotic patients. In conclusion, these patients should benefit from an early dietician intervention before liver transplantation.

Le niveau de violence, tel que mesuré par le taux d’homicide, varie beaucoup d’un pays à l’autre. Dans certains pays, on note un taux de 0,5 par 100,000 habitants tandis que pour d’autres, ce taux se situe autour de 50 par 100,000 habitants. Parmi les facteurs évoqués dans la littérature scientifique pour expliquer cette variation, on retrouve des concepts tels que la pauvreté, les inégalités et d’autres facteurs sociaux, économiques ou démographiques. Or, il y a relativement peu d’études qui examinent le rôle éventuel de la qualité du système de justice sur l’incidence de la violence. La présente étude s’intéresse au rôle de la corruption policière sur les variations du taux d’homicide entre les pays du monde. La corruption se définit comme le fait d’agir contre son devoir. Dans le cadre de l’activité policière, la corruption peut prendre la forme d’abus du pouvoir discrétionnaire, de recours à des moyens illégaux ou d’acceptation de récompenses. Considérant que ces différentes formes de corruption policière ont pour principale conséquence de créer des inégalités, il ne fait peu de doute que ce que font les policiers influence le taux de criminalité d’un endroit donné. Cette étude tente donc de déterminer s’il existe un lien entre le niveau de corruption policière et le niveau de violence, tel que mesuré par le taux d’homicide pour 143 pays. Des analyses statistiques univariées et bivariées sont réalisées afin de déterminer les indicateurs pertinents à inclure dans les différents modèles de régression multiple. Les résultats de nos analyses indiquent qu’une relation relativement forte et significative est retrouvée entre la corruption policière et le taux d’homicide. De plus, les résultats montrent que les inégalités influencent la corruption policière et que ces deux phénomènes influencent à leur tour le taux d’homicide.

The Ellen Evans Cathcart Papers consist of biographical sketches of Mrs. Ellen Evans Cathcart (1869-1952), first woman member of the Democratic National Committee who was also instrumental in the founding of the Children’s Bureau. Also included in the collection are newspaper clippings, magazine articles, correspondence, reports, certificates, citations, and photographs relating to her work as supervisor of the Children’s Bureau of South Carolina and her involvement in the women’s suffrage movement. Of particular note is an annual report of the South Carolina Council of Defense which outlines the achievements of women of South Carolina in war work and a program book of the 47th annual convention of the National American Woman Suffrage Association.
