Caribbean synthesis review and appraisal report in the context of the 15th anniversay of the adoptaton of the Beijing declaration and platform for action

The report is a summary based on information received by ECLAC from the eight English-speaking Caribbean countries of Barbados, Belize, the Cayman Islands, the Commonwealth of Dominica, Jamaica, Suriname, Saint Vincent and the Grenadines and Trinidad and Tobago in response to the questionnaire to governments on the Implementation of the Beijing Declaration and Platform for Action (1995) and the Outcome of the Twenty-Third Special Session of the General Assembly (2000). The report is therefore set in the context of the regional review and appraisals of the fifteenth anniversary of the adoption of the Beijing Declaration and Platform for Action in 2010. This Executive Summary highlights the achievements and the challenges for the Caribbean subregion in the progress towards implementation of the Beijing Platform of Action.

Caribbean synthesis review and appraisal report on the implementation of the Beijing Declaration and Platform for Action

The Caribbean sub-regional synthesis report, covering 12 countries, assesses progress towards the gender equality goals articulated in the 1995 World Conference on Women, which produced the Beijing Platform for Action (BPfA). The process leading to the preparation of the report has involved a series of national, regional and global consultations that will culminate in the Beijing + 20 Review. The process has also led to the formulation of the Caribbean Joint Statement on Gender Equality and the Post-2015, as well as the SIDS Agenda, both of which express Caribbean perspectives and expectations regarding gender equality.

Carbon and oxygen isotope geochemistry of Ediacaran outer platform carbonates, Paraguay Belt, central Brazil

Após a glaciação do final do Criogeniano, a região central do Brasil foi palco de extensa deposição de carbonatos plataformais do Grupo Araras. Este grupo inclui na sua base uma seqüência de capa carbonática sucedida por depósitos transgressivos de calcilutitos betuminosos e folhelhos de plataforma profunda. Dados de fácies e estratigráficos combinados com análises isotópicas de carbono e oxigênio da seção mais completa desses depósitos transgressivos, expostos no sinclinal da Guia, foram empregados para avaliar o paleambiente deposicional e para testar a correlação desses depósitos ao longo da faixa e também com outras unidades de outros continentes. A sucessão estudada consiste de 150 m de espessura de camadas tabulares de calcilutitos e folhelhos cinza a pretos com valores de d13CPDB negativos, entre -2,5 e -1 . O perfil de d13CPDB do sinclinal da Guia mostra clara correlação com a porção superior da Formação Guia da região de Cáceres, 200 km a sudoeste. O perfil de d13CPDB do Grupo Araras é comparável aos perfis de d13CPDB de outras unidades ediacaranas da parte sul da Faixa Paraguai, oeste do Canadá, e crátons do Congo e do Kalahari. Além disso, a distribuição de fácies, estratigrafia e o perfil isotópico do Grupo Araras são equiparáveis à porção média do Subgrupo Tsumeb na Namíbia, o que reforça a atribuição de idade Ediacarana para o Grupo Araras.

Influence of Platform and Abutment Angulation on Peri-Implant Bone. A Three-Dimensional Finite Element Stress Analysis

The aim of this study was to evaluate stress distribution on the pen-implant bone, simulating the influence of Nobel Select implants with straight or angulated abutments on regular and switching platform in the anterior maxilla, by means of 3-dimensional finite element analysis. Four mathematical models of a central incisor supported by external hexagon implant (13 mm x 5 mm) were created varying the platform (R, regular or S. switching) and the abutments (S, straight or A, angulated 15 degrees). The models were created by using Mimics 13 and Solid Works 2010 software programs. The numerical analysis was performed using ANSYS Workbench 10.0. Oblique forces (100 N) were applied to the palatine surface of the central incisor. The bone/implant interface was considered perfectly integrated. Maximum (sigma(max)) and minimum (sigma(min)) principal stress values were obtained. For the cortical bone the highest stress values (sigma(max)) were observed in the RA (regular platform and angulated abutment, 51 MPa), followed by SA (platform switching and angulated abutment, 44.8 MPa), RS (regular platform and straight abutment, 38.6 MPa) and SS (platform switching and straight abutment, 36.5 MPa). For the trabecular bone, the highest stress values (sigma(max)) were observed in the RA (6.55 MPa), followed by RS (5.88 MPa), SA (5.60 MPa), and SS (4.82 MPa). The regular platform generated higher stress in the cervical periimplant region on the cortical and trabecular bone than the platform switching, irrespective of the abutment used (straight or angulated).

Effect of mechanical cycling on screw torque in external hexagon implants with and without platform switching

This in vitro study evaluated the effect of mechanical cycling on the torque of retaining screw in external hexagon implants with platform switching (PS), regular platform (RP) and wide platform (WP). A total of 30 specimens were equally divided into 3 groups: PS, PR and WP. Each specimen was prepared with implants: 3.75 x 10 mm for RP group and 5.0x10 mm for PS and WP groups and its respective abutment with 32 Ncm torque. All groups were subjected to 106 cycles with 100 N (corresponding to about 40 months of chewing). The results were obtained with the reverse torque of each specimen and data were evaluated using ANOVA and Tukey test (p<0.05). The PS group showed statistically significant difference in screw removal torque (30.06±5.42) compared with RP (23.75±2.76) and WP (21.32±3.53) (p<0.05) groups; the RP and WP groups showed no statistically significant difference between them. It was concluded that the PS group showed higher reverse torque value, suggesting lower susceptibility of the abutment screw loosening.

Shark Attacks and Shark Diving Reply

It is with great astonishment and concern that I read the letter to the editor by Barreiros et al1 in which the authors report an attack by a blue shark on a spear fisherman in the Azores. Whereas the first part of the article accurately details the circumstances of the accident, Barreiros et al, in the second part, devise a far-fetched and illegitimate connection with shark diving, in particular with shark feeding.
