[Legal health services of abortion in Uruguay. Strategies of the primary health care public services].

Objective: To analyze the strategies developed by the health centers to implement the law of legal abortion (LA) in public services of the primary care in Montevideo, Uruguay.

Materials And Methods: A qualitative research was conducted combining techniques of document analysis, self-administered questionnaires to key informants, and in-depth interviews with directors of health centers. A simple summative index of accessibility to abortion services was built.

[Sexual and reproductive rights regarding contraception in a human rights framework in Bolivia, Colombia, and UruguayDireitos sexuais e reprodutivos de contracepção na Bolívia, Colômbia e Uruguai como parte dos princípios dos direitos humanos].

Objective: Compare World Health Organization (WHO) guidelines for contraception in a human rights framework with the existing regulatory frameworks of Bolivia, Colombia, and Uruguay and evaluate which aspects of those regulations need to be developed.

Methods: A systematic analysis was based on the WHO analytical framework "Ensuring human rights in the provision of contraceptive information and services: Guidance and recommendations" to determine whether the legislation of Bolivia, Colombia, and Uruguay contain general references to the population, specific references to adolescents, or do not refer to the topic. To this end, 36 documents related to contraception were analyzed: 9 from Bolivia, 15 from Colombia, and 12 from Uruguay.

Iron under pressure: "Kohn tweezers" and remnant magnetism.

In this work we investigate the magnetic and structural properties of bulk Fe and Fe nanoparticles under pressure with x-ray absorption and emission spectroscopies providing answers to two fundamental questions: (a) the chicken-or-egg problem for the magnetic and structural transitions and (b) magnetism in the high pressure hcp phase. The two transitions, inextricably linked in the bulk, are clearly decoupled in the nanoparticles, with the magnetic collapse preceding the structural transition. Ultrafast x-ray emission spectroscopy detects remnant magnetism, probably antiferromagnetic fluctuations, up to pressures of about 40 GPa in the hcp phase.
