El presente trabajo determinó factores de riesgo relacionados con la depresión post-parto en gestantes que asistieron al Hospital San Juan de Dios de Pamplona, durante el primer periodo académico del 2012. Para el logro de esta investigación se emplearon los principales conceptos teóricos de Cheril Tatano Back a través de la aplicación de instrumentos validados, tales como: Escala de Ansiedad, Depresión de Goldberg, Apgar familiar, Cuestionario de Apoyo social de Duke-UNC, Escala de Autoestima de Rosenberg, y la Escala de Depresión Postparto de Edimburgo a pacientes conscientes y orientados que accedieron voluntariamente a participar, gracias a esto se encontraron factores de riesgo que no fueron significativos para que las gestantes padeciesen depresión post-parto

Cognition and its relationship with endogenous and exogenous factors in engineering students

In this research, a relational study was carried out between student cognition with endogenous factors (student attitude and age) and exogenous (collegiate origin) in engineering students of the University of Cartagena. The project was carried out in three (3) phases where the survey allowed the desired information to be obtained from an estimated nine hundred sixty (960) students between 2014 and 2016. In the second phase, the instrument was used to collect the information, which was constituted the cognitive scale of the Self-Regulation Inventory for Learning (SRLI) and in the third phase, the independent endogenous and exogenous variables were crossed with the dependent one (student cognition), constructing the bar diagram of the relationship analysis; being possible to determine statistical significance with the attitude of the student to a level of confidence of 95% while with the age and collegial origin was not relevant

Conditions of work and dermatitis in workers exposed to chemical risks by cement

This research was carried out in order to identify the working conditions in workers exposed to cement in a cement factory in the city of Cartagena. Through different tools it was possible to carry out the diagnosis of the working conditions and to identify the hazards to which the workers of the company are exposed when being in direct contact with the cement; in this way it was possible to know that the dermatitis that were manifesting the workers has its direct relation with this chemical and therefore to be able to establish those measures tending to ensure the complete state of health of the workers. The type of research carried out is descriptive-qualitative, the applied methodology used as a closed questions survey tool, it was obtained as a result that 70% of the respondents did not use personal protection elements when handling cement, so can say that there is a considerable number of people exposed, which increases the likelihood that they may suffer contact dermatitis, through this the different preventive measures for working and health conditions among the employees of the cement company were raised

Multi-messenger observations of a binary neutron star merger

On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB 170817A) with a time delay of ~1.7 s with respect to the merger time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg2 at a luminosity distance of 40+8-8 Mpc and with component masses consistent with neutron stars. The component masses were later measured to be in the range 0.86 to 2.26 Mo. An extensive observing campaign was launched across the electromagnetic spectrum leading to the discovery of a bright optical transient (SSS17a, now with the IAU identification of AT 2017gfo) in NGC 4993 (at ~40 Mpc) less than 11 hours after the merger by the One- Meter, Two Hemisphere (1M2H) team using the 1 m Swope Telescope. The optical transient was independently detected by multiple teams within an hour. Subsequent observations targeted the object and its environment. Early ultraviolet observations revealed a blue transient that faded within 48 hours. Optical and infrared observations showed a redward evolution over ~10 days. Following early non-detections, X-ray and radio emission were discovered at the transient’s position ~9 and ~16 days, respectively, after the merger. Both the X-ray and radio emission likely arise from a physical process that is distinct from the one that generates the UV/optical/near-infrared emission. No ultra-high-energy gamma-rays and no neutrino candidates consistent with the source were found in follow-up searches. These observations support the hypothesis that GW170817 was produced by the merger of two neutron stars in NGC4993 followed by a short gamma-ray burst (GRB 170817A) and a kilonova/macronova powered by the radioactive decay of r-process nuclei synthesized in the ejecta

Campaign 9 of the K2 Mission: Observational Parameters, Scientific Drivers, and Community Involvement for a Simultaneous Space- and Ground-based Microlensing Survey

K2's Campaign 9 (K2C9) will conduct a ~3.7 deg2 survey toward the Galactic bulge from 2016 April 22 through July 2 that will leverage the spatial separation between K2 and the Earth to facilitate measurement of the microlens parallax ${\pi }_{{\rm{E}}}$ for $\gtrsim 170$ microlensing events. These will include several that are planetary in nature as well as many short-timescale microlensing events, which are potentially indicative of free-floating planets (FFPs). These satellite parallax measurements will in turn allow for the direct measurement of the masses of and distances to the lensing systems. In this article we provide an overview of the K2C9 space- and ground-based microlensing survey. Specifically, we detail the demographic questions that can be addressed by this program, including the frequency of FFPs and the Galactic distribution of exoplanets, the observational parameters of K2C9, and the array of resources dedicated to concurrent observations. Finally, we outline the avenues through which the larger community can become involved, and generally encourage participation in K2C9, which constitutes an important pathfinding mission and community exercise in anticipation of WFIRST

Evaluation of the Starch Quantification Methods of Musa paradisiaca, Manihot esculenta, and Dioscorea trífida Using Factorial Experiments

Background. Starch and its products are used in a variety of ways for both the food and nonfood industries. A factorial experiment is carried out with two factors to explain the behavior of the percentage of starch, where the factors correspond to the extraction method and to the raw material. Method. Three methods were used in triplicate: the first followed the official technique of the Association of Official Analytical Chemists (AOAC), to perform acid hydrolysis and quantification of starch by Titulation; the second method involved the colorful reaction with iodine using the UV equipment to measure the absorbance and calculate the percentage of starch; as a third method the FTIR was used, through which the concentration of the starch was calculated by the area under the curve obtained from the spectrum. Results. there is an effect of both the method and the raw material on the percentage of starch, while there was no effect of the interaction; the Tukey test indicates that the highest average percentage of extraction occurs with the extraction method by Titulation and with the starch of Manihot esculenta. Conclusion. It is used as raw material. The method of quantification of starch by UV-VIS spectroscopy was the best for the study samples because it presented less deviation in relation to the FTIR and Titulation methods

Environment and systemic protozoosis III. Vectors of Chagas’ disease and its association with climatic factors

La Enfermedad de Chagas es un grave problema de salud pública en los países latinoamericanos, causada por el parasito protozoo Tripanosomas cruzi y transmitido por insectos hematófagos de la subfamilia Triatominae. Al igual que todas las enfermedades transmitidas por vectores, la enfermedad de Chagas está fuertemente influenciada por las variables bioclimaticas. Actualmente el uso de la tecnología de Sistemas de Información Geográfica (SIG), esta permitiendo establecer índices que relacionan la distribución de los vectores con variables macroclimáticas (Vegetación, Humedad Relativa, Precipitación, Temperatura Media Anual etc.) ayudando a identificar de manera más exacta la extensión de las áreas de mayor riesgo de infestación, facilitando su monitoreo, vigilancia y simplificando el esfuerzo de la toma de datos de campo para la generación de modelos predictivos del riesgo entomológico en las diferentes áreas endé[email protected][email protected][email protected]@ula.ve, [email protected]’ disease is a serious problem of public health in the latin American countries, caused by the protozoan parasite Trypanosome cruzi and transmitted by hematophagus insects of the subfamily Triatominae.
