Factores Socioculturales Que Interfieren En La Realización Del Papanicolaou En Mujeres Indígenas Mexicanas

Introduction: Papanicolaou test was introduced in 1943 by the Dr. George Papanicolaou as an examination of early detection for the Cancer Cérvico Uterino (CACU), it is the most frequent test of detection in women who do not have symptoms. It is the most common second type of cancer in women, of the different types of cancer that they affect the women in reproductive present age in developing countries, rural populations and indigenous zones. I target: to identify the sociocultural factors that they interfere in the accomplishment of the Papanicolaou in wives of a community indigenous to Saint Thomas of Tenosique municipality of Pino Suárez, Tabasco. Methodology: Quantitative descriptive, market investigation across the sampling not probabilistic for incidental convenience with one n = 23 women with ages between 25 and 35 alive years sexual activates. Results: Results: it predominated over the item of age between 29 and 35 years; the level of education that prevails is the primary one, for the marital status the majority is in free union and up to the moment it has had 2 sexual pairs in his life; the beginning of sexual active life that prevails is 16 to 20 years, and the Papanicolaou has never been realized by motives of lack of interest, by the influence of the pair and for not knowing the purpose of there being realized the procedure of periodic form. Conclusion: This study demonstrates that the women have an indifferent attitude towards Papanicolaou capture; since 83.3% of the women presents this attitude, of equal way 70.8 % agrees very in that there is important the opinion of his pair the test to take.

A MODEL OF THE ARTERIAL WALL INTERACTION WITH A BLOOD PRESSURE SENSOR TRANSDUCER FIXED IN PROXIMITY

MEMS technology is an option for the development of a pressure sensor which allows the monitoring of several bio-signals in humans. In this work, a comparison is made between the typical elasticity and viscosity presented in several arteries in the human body and those present in MEMS silicon microstructures based on membranes in proximity with an arterial wall. The main purpose is to identify which types of microstructures are mechanically compatible with human arteries. The ultimate goal is to integrate a blood pressure sensor which can be implanted in proximity with an artery. The expected benefits for this type of sensor are mainly the reduction in problems associated with the use of bulk devices through the day and during several days. Such a sensor could provide precise blood pressure readings in a continuous or periodic form, i.e. information that is especially important for some critical cases of hypertension patients. The modeling work involved in this paper, accounts for the analysis of micro displacements present in the membrane of a MEMs silicone microstructure placed directly on a human arterial wall, at different heart rates. The modeling includes the effects of elasticity and viscosity of the silicone structure on the pressure measurement. Additionally, the sensitivity of the membrane to detect slight variations in the blood pressure is presented.

Homotopic Approximate Solutions for the Perturbed CKdV Equation with Variable Coefficients

This work concerns how to find the double periodic form of approximate solutions of the perturbed combined KdV (CKdV) equation with variable coefficients by using the homotopic mapping method. The obtained solutions may degenerate into the approximate solutions of hyperbolic function form and the approximate solutions of trigonometric function form in the limit cases. Moreover, the first order approximate solutions and the second order approximate solutions of the variable coefficients CKdV equation in perturbationεunare also induced.

Statistical analysis of ionospheric potential patterns for isolated substorms and sawtooth events

We present here results which contrast isolated substorms with individual sawtooth events. Sawtooth events are defined as quasi-periodic, large-amplitude oscillations in the energetic particle flux with a periodicity of 2–4 h observed at the geosynchronous orbit. Sawtooth events have several similarities to isolated substorms leading therefore, to different opinions about whether sawtooth events are just an intense periodic form of substorms or if they deserve a category of their own. To help resolve this, we examine the ionospheric potential patterns in the northern polar region for isolated substorms and sawtooth events using the assimilative mapping of ionospheric electrodynamics (AMIE) technique. First we show a statistical analysis of isolated substorm potential patterns. In order to examine the seasonal variation, isolated substorms are identified by mid-latitude positive bay in the north-south geomagnetic perturbation in each season, respectively. Superposed epoch analysis (SEA) is applied to obtain the typical polar potential patterns for each season. By examining the time evolution of the potential patterns and cross polar cap potential (CPCP) for isolated substorms during each season, we find only subtle seasonal variations in the results obtained using the AMIE analysis. This provides a basis for comparison with sawtooth events in the next step. From the averaged potential patterns of 213 isolated substorms and those of 184 individual sawtooth events, we find the sawtooth events show signatures similar to subtorms: the DP 1 potential pattern develops and dominates the polar region after the onset. However, the DP 1 potential cell of sawtooth events encompasses a larger area than that of isolated substorms. Moreover, the CPCP of sawtooth is stronger than that of isolated substorms. It is also shown that the sawtooth events displays greater variability between individual events than isolated substorms. We conclude that in terms of ionospheric electrodynamics, the sawtoothe events have features that are similar to those of isolates substorms, though larger in spatial extent and in magnitude.

STATICS OF RIGID UNITS CHAIN

The statics of one-dimensional rigid units chain subject to stretching force is analyzed. The potential energy of adjacent units interaction is assumed in the simple periodic form (harmonic in the small distortion limit). The position angles of subsequent units are given by the system of two iteration equations, one of them being irreversible. The derived system of equations exhibits interesting properties significantly different from those of the standard system which describes the chain in the harmonic approximation.
