Next-to-leading order QCD evolution of transversity fragmentation functions
We derive the next-to-leading order splitting kernels for the scale evolution
of fragmentation functions for transversely polarized quarks into transversely
polarized hadrons.Comment: 9 pages, LaTe

Portable flow multiplexing device for continuous, in situ biodetection of environmental contaminants
A compact, low-cost and low-powered device was developed and arranged for multiplexed biodetection of sea water contaminants from continuous flow mode. Electronics, mechanics and fluidics were designed to guarantee identical functional liquid flow through eight parallel sensor microchambers during a predetermined time period providing 8 values at the same time. The accuracy and repeatability of the device was tested in-lab, achieving a deviation of less than 10% when measuring the same analyte in all the chambers. The experimental results obtained with our device were finally compared with those measured in continuous flux by a commercial potentiostat SP150 (Bio-Logic Science Instruments), obtaining identical results, which validated the proposed device
Niños y niñas migrantes de retorno a México y problemáticas educativas
The objective of this research was to know the problems faced by migrant children returned from the United States to Mexico, in their incorporation into basic education institutions. It is a qualitative research, an exploring study, carried out in five elementary schools (public and private) in the municipality of Jerez de García Salinas, Zacatecas, México, distinguished by his historical and important participation in the migration of its population to the United States, with techniques such as non-participant observation and semi-structured interview (to key indirect informants: directors, teachers, and parents of returning migrant children). The results obtained allow us to conclude that they are children who have made visible the absences that subsist in the Mexican Educational System to attend this population segment that is incorporated to the schools, to continue their schooling, already initiated in the US, highlighting as the main problems the language, teachers without training from bilingualism, the organization of special courses that favor the learning of Spanish (communication, writing and reading) for returning students, as well as training for the integration and inclusion of children return.El objetivo de esta investigación fue conocer los problemas que enfrentan los niños y niñasi migrantesretornados de Estados Unidos a México en su incorporación a las instituciones de educación básica. Se utiliza la metodología cualitativa, un estudio exploratorio realizado en cinco escuelas de educación primaria, localizadas en la cabecera municipal de Jerez de García Salinas, Zacatecas, México, municipio que se distingue por su histórica e importante participación en la migración de su población hacia Estados Unidos. Se recurrió a la observación no participante y la entrevista semiestructurada aplicada a informantes indirectos clave(directivos y docentes de los planteles, y los padres de los menores de retorno). Los resultados obtenidos permiten concluir que los menores de retorno han visibilizado las ausencias que subsisten en el Sistema Educativo Mexicano para la atención de este segmento poblacional, que se incorpora a las escuelas para dar continuidad a su escolaridad ya iniciada en Estados Unidos, destacando como principales problemáticas el idioma, docentes sin formación desde el bilingüismo, la organización de cursos especiales que favorezcan el aprendizaje del español (comunicación, escritura y lectura) para los menores de retorno, así como capacitación para la integración e inclusión de los niños y niñas de retorno.

La perspectiva de los estudiantes sobre la pertinencia de la tutoría en el posgrado
This work is part of a broader descriptive research that involved teachers and students. He caught investigate the tutorial process from the concept of relevance and east, the way they respond to educational quality for Two objectives were set: determine the tutorial teacher support graduate students in transit and determine the relevance of the tutorials based on the criteria of educational quality that allows the design of strategies and lines of research in the field of tutorials in graduate school. In this, through case study, using survey questionnaire and interview students, which concluded that the relevance and mentoring are aspects of evidence through action and adaptation between what society expects were applied IES and what they do through teacher and student.ste trabajo es parte de una investigación descriptiva más amplia, que involucró a docentes y estudiantes. Se pretendió investigar el proceso tutorial desde el concepto de pertinencia y de este, la manera en que responde a la calidad educativa, para ello se plantearon dos objetivos: determinar el apoyo tutorial del docente de posgrado al estudiante en tránsito y determinar la pertinencia de las tutorías en función de los criterios de calidad educativa que permita el diseño de estrategias y líneas de investigación en el campo de las tutorías en el posgrado. En este, a través del estudio de caso, mediante encuesta se aplicaron un cuestionario y entrevista a los estudiantes, donde se concluye que la pertinencia y la tutoría son aspectos de evidencia a través de la acción y la adecuación, entre lo que la sociedad espera de las IES y lo que éstas hacen a través del profesorado y del estudiante
