Revista de la Sociedad Entomol?3gica Argentina , 2012,
Abstract: Nematus oligospilus F rster (Hymenoptera: Tenthredinidae) is a willow sawfly native to the Northern Hemisphere which became a serious defoliator in willow plantations (Salix spp.) of the Southern Hemisphere after being introduced in the early 1980′s. Studies on host preferences provide useful information for the development of pest management strategies where the willow sawfly may produce tree damage and economic loss. Feeding preferences of N. oligospilus larvae were evaluated in laboratory trials by simultaneously offering leaves from four willow tree clones commonly used in commercial plantations in Argentina (Salix babylonica var sacramenta Hortus, Salix nigra Marsch., S. babylonica L. x Salix alba L. 131-27 and Salix matsudana Koidz. x S. alba L. 13-44). Larvae of N. oligospilus fed on leaves from the four clones. However, insects consumed a significantly higher proportion of S. babylonica var sacramenta leaves than of leaves from the other clones. Results indicate that all clones used in the trials were palatable to the insect, and that S. babylonica var sacramenta is the preferred host for larval herbivory. Nematus oligospilus F rster (Hymenoptera: Tenthredinidae), o la avispa sierra de los sauces, es nativa del Hemisferio Norte y se ha convertido en un serio defoliador en plantaciones de sauces (Salix spp.) del Hemisferio Sur, después de su introducción a principios de 1980. Los estudios sobre las preferencias de hospedador aportan información útil para el desarrollo de estrategias, donde la avispa sierra puede producir da o a los árboles y pérdidas económicas. Se evaluó la preferencia alimentaria de las larvas de N. oligospilus, mediante ensayos de laboratorio; se ofrecieron en forma simultánea hojas de cuatro clones de sauce, usados comúnmente en plantaciones comerciales en Argentina (Salix babylonica var sacramenta Hortus, Salix nigra Marsch., S. babylonica L. x Salix alba L. 131-27 and Salix matsudana Koidz. x S. alba L. 13-44). Las larvas de N. oligospilus se alimentaron de las hojas de los cuatro clones. Sin embargo, consumieron una proporción significativamente mayor de las hojas de S. babylonica var sacramenta. Estos resultados indican que todos los clones utilizados en los ensayos fueron palatables para el insecto y que S. babylonica var sacramenta es el hospedador preferido para la herbivoría de las larvas.
Nanoscale resolution for fluorescence microscopy via adiabatic passage

Physics , 2015, DOI: 10.1364/OE.21.022139
Abstract: We propose the use of the subwavelength localization via adiabatic passage technique for fluorescence microscopy with nanoscale resolution in the far field. This technique uses a {\Lambda}-type medium coherently coupled to two laser pulses: the pump, with a node in its spatial profile, and the Stokes. The population of the {\Lambda} system is adiabatically transferred from one ground state to the other except at the node position, yielding a narrow population peak. This coherent localization allows fluorescence imaging with nanometer lateral resolution. We derive an analytical expression to asses the resolution and perform a comparison with the coherent population trapping and the stimulated-emission-depletion techniques.

Abstract: Objetivo: identificar los factores que se relacionan con mortalidad perinatal de la población afiliada a una EPS del departamento de Nari o durante 2007. Materiales y Métodos: la investigación fue de tipo cuantitativo, descriptivo, retrospectivo-evaluativo, dado que los datos corresponden a la revisión documental realizada a las historias clínicas de las gestantes con eventos de mortalidad en el a o 2007. Se tomó el 100% de los casos de mortalidad perinatal, lo cual representó el total de la población. Se estudiaron las variables socio-demográficas; se realizó análisis de casos (manejo de protocolo de atención, diligenciamiento de ficha de notificación, cumplimiento de las normas técnicas y guías de atención). Se estudiaron 34 eventos, de los cuales 61,8% murieron en el ante-parto, 20,6% en el intra-parto y 17,6% en la pre-alta. Se dise ó una ficha de verificación, se aplicó a los eventos, los datos se consolidaron en el sistema estadístico de información EPIINFO versión 2000, y se realizó el cruce de variables existentes. Una vez identificados los hallazgos en cuanto a las causas de riesgo, se aplicó el chi2 y determinando el valor de P, se levantó la línea de base con el fin de priorizar planes o proyectos enfocados a la reducción del indicador de mortalidad perinatal para la EPS. Resultados: de la población total las madres con edades comprendidas entre 23 y 26 a os de edad, registran el mayor número de casos, procedentes el 56% de cabecera municipal quienes tenían un grado de escolaridad de primaria completa, el 23% con cónyuge, el 26% presentaban antecedentes de multiparidad; durante el embarazo asistieron a cuatro controles realizados por médico general en el primer nivel de atención, de ellas el 67% no utilizaban método de planificación familiar. Con relación a los riesgos que tenían las madres se encontraron 3 casos con hipertensión crónica; infecciones urinarias 3 casos; tabaquismo, alcoholismo y alteraciones sicológicas, así como retardo en el crecimiento intrauterino fue reportado un caso; los cuales fueron clasificados como embarazo de alto riesgo; 6 embarazos no se clasificaron, los cuales sí tenían aspectos relevantes a tener en cuenta. El estudio demostró la omisión al momento de escribir o consignar aspectos en la historia clínica. En el proceso de parto y puerperio se identificaron las semanas de gestación entre las 28 y 40 semanas, de las cuales el 71% tuvo parto vaginal; 26,57% cesárea, de las cuales la mitad fueron atendidas por médico obstetra y el restante por médico general; el 11% no registra datos y el 5% corresponde a otros.

Revista médica de Chile , 2002,
Abstract: Background: The prevalence of periodontal diseases, gingivitis and periodontitis, is higher in diabetic patients and can have severe functional and esthetic consequences early in their lives. Aim: To evaluate the prevalence of periodontal disease in type 1 diabetics, aged between 18 and 30 years old, living in Santiago de Chile. Subjects and methods: One hundred male and female type 1 diabetics were examined. Glycated hemoglobin A1c, microalbuminuria, and fundoscopy were assessed in a sample of 52 subjects, separated in two groups according to the presence of periodontal disease. Results: The prevalence of gingivitis was 22%, periodontitis 41%. Only 37% of subjects were free of periodontal disease. When compared with patients without periodontal disease, in the group of patients with the disease there was a higher proportion of subjects with diabetes lasting more than 10 years (28 and 55% respectively) and a higher proportion of patients with chronic complications of diabetes (42 and 58% respectively). Conclusions: A high prevalence of periodontal diseases was observed in this sample of diabetic patients. A long history of diabetes and the presence of chronic complications were risk factors for these diseases in the analyzed sample (Rev Méd Chile 2002; 130: 402-408)
Crop Biometric Maps: The Key to Prediction
Francisco Rovira-Más,Verónica Sáiz-Rubio
Sensors , 2013, DOI: 10.3390/s130912698
Abstract: The sustainability of agricultural production in the twenty-first century, both in industrialized and developing countries, benefits from the integration of farm management with information technology such that individual plants, rows, or subfields may be endowed with a singular “identity.” This approach approximates the nature of agricultural processes to the engineering of industrial processes. In order to cope with the vast variability of nature and the uncertainties of agricultural production, the concept of crop biometrics is defined as the scientific analysis of agricultural observations confined to spaces of reduced dimensions and known position with the purpose of building prediction models. This article develops the idea of crop biometrics by setting its principles, discussing the selection and quantization of biometric traits, and analyzing the mathematical relationships among measured and predicted traits. Crop biometric maps were applied to the case of a wine-production vineyard, in which vegetation amount, relative altitude in the field, soil compaction, berry size, grape yield, juice pH, and grape sugar content were selected as biometric traits. The enological potential of grapes was assessed with a quality-index map defined as a combination of titratable acidity, sugar content, and must pH. Prediction models for yield and quality were developed for high and low resolution maps, showing the great potential of crop biometric maps as a strategic tool for vineyard growers as well as for crop managers in general, due to the wide versatility of the methodology proposed.

Abstract: Background Corruption pervades educational and other institutions worldwide and medical schools are not exempt. Empirical evidence about levels and types of corruption in medical schools is sparse. We conducted surveys in 2000 and 2007 in the medical school of the Autonomous University of Guerrero in Mexico to document student perceptions and experience of corruption and to support the medical school to take actions to tackle corruption. Methods In both 2000 and 2007 medical students completed a self-administered questionnaire in the classroom without the teacher present. The questionnaire asked about unofficial payments for admission to medical school, for passing an examination and for administrative procedures. We examined factors related to the experience of corruption in multivariate analysis. Focus groups of students discussed the quantitative findings. Results In 2000, 6% of 725 responding students had paid unofficially to obtain entry into the medical school; this proportion fell to 1.6% of the 436 respondents in 2007. In 2000, 15% of students reported having paid a bribe to pass an examination, not significantly different from the 18% who reported this in 2007. In 2007, students were significantly more likely to have bribed a teacher to pass an examination if they were in the fourth year, if they had been subjected to sexual harassment or political pressure, and if they had been in the university for five years or more. Students resented the need to make unofficial payments and suggested tackling the problem by disciplining corrupt teachers. The university administration made several changes to the system of admissions and examinations in the medical school, based on the findings of the 2000 survey. Conclusion The fall in the rate of bribery to enter the medical school was probably the result of the new admissions system instituted after the first survey. Further actions will be necessary to tackle the continuing presence of bribery to pass examinations and for administrative procedures. The social audit helped to draw attention to corruption and to stimulate actions to tackle it.
