CHALLENGES TO THE ORGANIZATION OF A CERVICAL CANCER SCREENING PROGRAM IN MANAUS-AM

The purpose was to investigate sociodemographic characteristics of women who underwent a Pap smear test in Manaus, Amazonas, Brazil, and identify the reasons why the women had the test. This exploratory study was performed with 281 women who had taken the Pap smear test within the last five years in Manaus. Most participants were between 18 to 34 years old (54%), had 5 to 11 years of education (54.4%), had a monthly income of less than three minimum wage salaries (84.3%) and were in a stable relationship (72.2%), with an onset of sexual activity between the ages of 15 to 19 years (69.4%). The reasons for their taking the Pap test were personal choice (66.2%), recommendation by a physician (23.5%) and gynecological symptoms (10.3%). Women who received information about the Pap test from health professionals had a greater chance of being tested within the last three years (p=0.008). Women choosing to have the exam (personal choice) are prevalent, and the opportunistic service is provided to younger women, thus not reaching the group at greater risk for cancer. It is necessary to implement active recruitment strategies to reach women in situations of socioeconomic disadvantage.

Experimental evidence for the sensitivity of the air-shower radio signal to the longitudinal shower development

We observe a correlation between the slope of radio lateral distributions and the mean muon pseudorapidity of 59 individual cosmic-ray-air-shower events. The radio lateral distributions are measured with LOPES, a digital radio interferometer colocated with the multidetector-air-shower array KASCADE-Grande, which includes a muon-tracking detector. The result proves experimentally that radio measurements are sensitive to the longitudinal development of cosmic-ray air showers. This is one of the main prerequisites for using radio arrays for ultra-high-energy particle physics and astrophysics.

Population synthesis of isolated neutron stars with magneto-rotational evolution – II. From radio-pulsars to magnetars

Population synthesis studies constitute a powerful method to reconstruct the birth distribution of periods and magnetic fields of the pulsar population. When this method is applied to populations in different wavelengths, it can break the degeneracy in the inferred properties of initial distributions that arises from single-band studies. In this context, we extend previous works to include X-ray thermal emitting pulsars within the same evolutionary model as radio-pulsars. We find that the cumulative distribution of the number of X-ray pulsars can be well reproduced by several models that, simultaneously, reproduce the characteristics of the radio-pulsar distribution. However, even considering the most favourable magneto-thermal evolution models with fast field decay, lognormal distributions of the initial magnetic field overpredict the number of visible sources with periods longer than 12 s. We then show that the problem can be solved with different distributions of magnetic field, such as a truncated lognormal distribution, or a binormal distribution with two distinct populations. We use the observational lack of isolated neutron stars (NSs) with spin periods P > 12 s to establish an upper limit to the fraction of magnetars born with B > 1015 G (less than 1 per cent). As future detections keep increasing the magnetar and high-B pulsar statistics, our approach can be used to establish a severe constraint on the maximum magnetic field at birth of NSs.
