La Metrología es importante en los procesos que se desarrollan en la atención médica, así como en la docencia y la investigación para elevar la calidad en los resultados de los servicios de salud. El objetivo de esta investigación es caracterizar la actividad de metrología en la provincia de Matanzas durante el período de enero del 2013 a septiembre del 2016 como parte de la garantía de la calidad en los servicios de salud. Para ello se realizó un estudio descriptivo retrospectivo donde se revisaron todos los informes semestrales y anuales de la actividad que realiza el departamento de investigaciones y envía al Ministerio de salud pública y la dirección provincial de salud. La selección y capacitación del personal permitió durante este periodo que la ejecución de la contratación del servicio de verificación y calibración por parte de las unidades tanto de atención primaria como secundaria esté al 100 %. La participación en los cursos no es elevada, debido a la estabilidad del personal en las unidades de salud municipales y hospitalarias. El desarrollo de la actividad permitió una mejor preparación de los profesionales y técnicos vinculados a la tecnología biomédica. Además de cumplir con la estrategia del Ministerio de Salud Pública a fin de garantizar el uso correcto de los instrumentos de medición, la exactitud de las mediciones y resalta la importancia que tiene la metrología en los equipos biomédicos, y como este impacta en las actividades orientadas a la confiablidad de los resultados.

O principal objetivo deste trabalho de pesquisa foi avaliar o efeito do ácido pirolânico e a dose ideal para a germinação de melancia, coco e sementes de cacau; o modelo estatístico utilizado foi um projeto completamente aleatório, os fatores em estudo foram: dose de ácido pirolânico obtido de Bambu, Pisonay e Cético (1, 10, 100 ml) e sementes das três espécies mencionadas, trabalhamos com 9 tratamentos e um controle mais três réplicas, as variáveis foram: porcentagem de germinação e dose. Os resultados mostram efeitos significativos do ácido pirolânico na germinação das sementes de cacau, cacau com 96,70% e 100%, entretanto, houve efeitos negativos para as sementes de melancia. Da mesma forma, a aplicação de ácido pirolânico na dose de 10 ml teve os melhores resultados na germinação do cacau e das sementes de cacau com 97% e 90%. Em conclusão, a aplicação de ácido pirolânico em uma dose de 10 ml melhorou o processo de germinação das sementes de Cocona e Cacau, porém, em uma dose alta de 100 ml inibiu a germinação, finalmente, a dose de 1 ml não mostrou efeitos positivos respectivamente.

The objective of the study was to determine the bacteriological quality of water for human consumption and the acute diarrheal disease, in the district of Rázuri. Province of Ascope. Department of La Libertad - Peru. Depending on the type of research is applied and quantitative. Method: prospective study, statistical, interpretative, documentary and judgmental. With a quasi-experimental design with longitudinal cut. The samples of water were collected from 14 localities in 03 sampling points: In well, in reservoir and public network; and microbiological analyzes of water were assessment by the laboratory of the Office of Environmental Health of the sub management of the promotion of the Territorial Management - GERESA / LL. For the determination of acute diarrheal disease (ADD) the data are taken from the record of medical consultations of the Health Center of Rázuri - MINSA and Logging Software doctor - Health Post Malabrigo - ESSALUD. 2018. In the statistical validation was used the non-parametric test Fisher exact test and Chi square test both with a confidence level of 95%, determined in terms of bacteriological quality of the water suitable for the towns of Puerto Malabrigo, dry bush, Paradise, The Pearl of Macabí, Macabí High, Line, Pancal and within groups of unfit for the towns of San Mateo, El Palomar, Santa Rosa, the García, The Corlib, The Algodonal, and the New Paradise. The drinking water is safe for human consumption to 100 per cent for the urban area administered by SEDALIB and 50 per cent for the rural area administered by JASS. Attended to 318 (77%) cases of aqueous EDA from the urban area. It is concluded that there is no statistically significant difference in the bacteriological quality of drinking water chlorinated administered both in the urban area and the rural area. There is no significant difference in the cases of EDA between the urban area and the rural area. In the urban area, administered by SEDALIB, there is an inverse relationship between chlorinated water suitable for human consumption with respect to the presence of bacteria, therefore, cases of EDA may have other sources such as the consumption of contaminated food; whereas, for the rural area, administered by JASS, these may be due both to water as to contaminated food.

In the present research was determined the effect of using the recycled concrete aggregates (RCA) as raw material in the elaboration of concrete for the construction of houses in the city of Huamachuco. Portland cement Type I, 1/2 "and 3/4" gravel, coarse sand and aggregates of recycled concrete were used as raw material for the design of mixtures, these last replacing coarse sand and gravel in the percentages by volume of 50%, 75% and 100% respectively. Specimens of simple concrete and concrete containing RCA were prepared according to Peruvian Technical Standard 339.033, then the compression test was performed on the specimens after 7, 14 and 28 days of curing, according to ASTM C39, so the concrete containing 50% RCA showed the best compressive strength, reaching 200.18 kg/cm2. Also, it was observed that the compressive strength of the concrete containing 100% ACR after 14 days presents an almost linear tendency. Finally, the inventory for the life cycle assessment (ACV) of the concrete was elaborated, this information will serve to realize the ACV of the concrete using for that purpose the OPENLCA free software.

The double production season in agriculture, in other words, is to obtain two harvests in one year, the same that is important to consider in an efficient and profitable agriculture, so it is important that the agri-food sector must adapt to the pace of competitiveness necessary to become true market-oriented production centers with fair prices, improving management models, process control to facilitate decision making and incorporate technological advances; In many places irrigation projects have been carried out to facilitate the proper use and management of irrigation water; however, many of them do not consider the very important aspect of "agricultural development", which is the decisive activity for evaluating the impact of the project and which will ultimately justify the investment made when farmers improve their income through better organization, application of technologies, negotiation capacity and greater profitability of their products, and consequently improve their standard of living and quality of life. This document presents the research work carried out in the Mantaro Valley and other areas of the Junin region - Peru, with good results considering crops tolerant to low temperatures, early and with good profitability, efficient use of irrigation water and also proposes a basic crop table that can be considered for other inter-Andean areas.

The political events of a nation rule the agglomerated milestone of opinion figures, who agitate the masses for a particular political ideology. That representation is subject to politicians representing a political party, at the same time it has to be based on programmatic ideologies with a journalistic dissemination body that points to a rule in its historical process, for example the ideological struggles in the journalistic industries: “The group tends to assimilate all the elements capable of claiming socialism without excepting those that come from gonzalezpradista radicalism and are preserved outside the political parties ”(Mariátegui, 1986, p.99)

Fundamentalism conceived as the fanatic and extreme expression of a religious (and / or political) ideology that considers itself as having an unequivocal truth, because it is believed to come from above, is not a new phenomenon, it is latent in any religion. Fundamentalism arises as a reaction, which can even be violent, to the change of mentality and customs produced by people who are considered sinners, evil, deceived or demonized. In circumstances of great ignorance and material need fundamentalists will grow in number, but that does not prevent them from arising in any social class or time. Only an early humanist and scientific education can foresee the emergence of fundamentalist groups within a society, or at least do so in a large number of them.

En julio del año pasado, la fiscalía pidió al decano de la Facultad de Letras de la UNMSM informe sobre unas conferencias cuyo tema había sido el marxismo. Sin duda, esto estaba fuera de lugar, si consideramos que vivimos en una democracia. Quizá todavía son temores de los años 80 y 90, del siglo pasado, dado que el grupo terrorista Sendero Luminoso estaba alimentado por el marxismo, interpretado por su líder.

In the present text, the concept of areté or virtue without moral content as it was used in the Hellenic and classical period of Greek history is going to be worked on very briefly. It will be possible to appreciate the way in which the apparent adjectives that appear qualifying the names of different historical or mythical personages are in fact the enunciation of the areté that characterizes the individuals.

Bringing the knowledge addressed in school to what is required for the students' personal, intellectual, social and professional qualification is challenging.
