El Cacao Community, municipality of Mozonte, Nueva Segovia department is located to 234 km from the capital Managua. In winter they feed of the water of creeks and gullies, while in summer they feed of a water eye where there are some minimum installations for storage and distribution. Physicochemical studies, microbiological, pesticide and wave metals; determined the presence of diverse types of pollutants from chemically nature principally microbiological in these waters. It has shown that 123 persons use the source in study (54 % adults, 43% child and 3 % elders). The applied surveys to 24 family heads form El Cacao Community, show a relation between sanitary education and quality of the water, because the people lack of the knowledge of the hygienic sanitary procedure orientated to improvement of the living conditions. Demonstrating this way, the existing relation between educational level and the family´s income levels with the conditions of health observed and their relation with the water management form the source until the home. Concluding that the life expectancy of the persons in this community is low and this one below the national value (75.1 years).

In this paper the study of erosivity rainfall factor in the Xolotlán Lake sub catchment is exposed, that belong to the 9525 catchment from Nicaragua. The objective of the study was to determinate the Revised Universal Loss Equation (RUSLE) erosivity factor”, from daily pluviograph data of the station 69027 (Managua Airport) and monthly pluviometric data in 7 stations distributed in the sub catchment and nearby. A simple lineal regression was done with the monthly R and monthly precipitation, with a correlation coefficient of r2 = 0.86.  Since in the sub cathcment there is only one pluviograph station, the Modified Fournier Index was used to estimate de R values in the pluviometrics stations. The study suggests that the annual mean erosivity factor rage from 5,000 Mj mm / (ha-h-year) in the lower side of the sub catchment to 7,250 in the upper side, that represent a rain with a moderate erosivity power.

This article will present the design and implementation of a plant in an industrial company that allows the reuse of solid waste from the tanning process during the process of making hides for use in a complementary process. The problems that arise when not having this type of process is incurring in extra costs to outsource services for the disposal of these wastes, contributing to the increase of pollution in the city. To implement this improvement, it will be necessary to carry out a preliminary analysis to be able to elaborate the most optimal plant design proposal that fits this process. The production line is made up of four Units, the first Raw Material Conditioning Unit; the second Mixing and Molding Unit; the third Pressing and Drying Unit, and finally the Finishing Unit.

The helical coil heat exchangers are employed in several applications due to their compact structure and the high heat transfer coefficients usually obtained. In the present work, the design of a helical coil heat exchanger is accomplished in order to carry out the cooling of a liquid acetone stream. The equipment will has an overall heat transfer coefficient of 23.88 kcal/h.m2.ºC; a heat transfer area of 6.60 m2; an actual number of turns of coil equal to 53; and a height of 2.58 m. Both the acetone and the water stream do not exceed the maximum pressure drop established by the process.  The influence of increasing both the acetone feed flowrate and inlet temperature on four design parameters of the helical coil heat exchanger: global heat transfer coefficient, heat transfer area, actual number of turns of the coil, and height of the equipment, was also determined, obtaining as a result that the increase of the two initial variables increases the values ​​to be obtained of these four parameters. Excel spreadsheets were used to obtain the graphics and to solve the design methodology used in this study.

In the present study an evaluation of the effect of four additives on the ceramic body is made: fly ash, talc, kaolin and feldspar; with the objective of determining the best formulations that allow to develop, after the thermal cycle and without modifications to the current production process of a certain ceramic company, microstructures that increase the mechanical resistance of semigres ceramic tiles. The obtaining of the ceramic test pieces was carried out using the procedure and the formulation proposed by the production company. The properties studied were linear contraction percentage, water absorption and mechanical resistance to bending. The corresponding tests were carried out in accordance with the corresponding standards. The highest value of mechanical resistance to bending was 57.91 N / mm2 corresponding to ceramic specimens with the optimized formulation: standard body plus 2% talc and 2% kaolin.

Introduction: The death of a mother is one of the most traumatic experiences that families suffer. Health services must be prepared to care for women during pregnancy, childbirth and the puerperium. In 2011, Guatemala reported a high number of these deaths related to the high levels of precariousness and vulnerability of women. Objective: To identify the sociodemographic and health care characteristics of the cases of maternal death reported in Alta Verapaz, Guatemala between 2012 and 2015. Methods: A descriptive cross-sectional study was performed. The universe consisted of 182 women who died due to causes associated with pregnancy, childbirth and the puerperium in Alta Verapaz. Information was obtained from the mortality records that were summarized in percentages and rates. Results: Maternal mortality affected the 17 municipalities in Alta Verapaz. The ratio was 273.55 per 100,000 registered live births. The main causes were: hemorrhages, pregnancy-induced hypertension and sepsis. 71% of those killed corresponded to the first three delays related to family and community. Conclusions: Maternal death represents a public health problem that can be reduced with proper health management.

Introduction: International solidarity is a core principle of our social process and in the field of health has achieved irrefutable results for countries that have requested it for free, or paid. Everyone knows that it has become a basic source of income to support the costs of the Single Health System that transcends, by far the possibilities as a poor and blocked country. In recent months statements by state leaders aimed at distorting their purposes and quality have circulated. Objective: Contribute to the health team, axiological, deontological, historical and social arguments, which refute said pronouncements. Positioning: The arguments based on a dialectical logical thought are exposed, guided by principles of objectivity, multi factoriality, systemic, historical and the experience derived from the own practice and teaching of our national and foreign teachers, who show the management of health, its historical stages, motivations, objectives, ethical-moral values and universality of their duties. Conclusions: Cuba is one of the countries in the region that incorporated the principle that we are a region of peace, and our purpose is to achieve peaceful coexistence with states and people who are not yet friends but we know that compassionate solidarity, willingness to help and benefit in the fields of health and education, the philosophical position, the political affiliation, the beliefs and the legitimate personal interests, transcend.

The depredatory editorials' inadequate practices prove that the same are manifestations of corruption to transnational level in the academic context. The objective of the article was to explore the knowledge that the professionals on the publications in editorials and depredatory magazines present. A transverse exploratory study with a concurrent design that you hold a mixed focus came true. A sampling took effect not probabilistic for opportunity to 238 professionals of social sciences and woman doctors in investigation. Straightaway you applied over yourself an exploratory questionnaire and the analysis of the information made of qualitative intervening way units of analysis of contents itself than after they quantified themselves regarding the frequency of appearing in the sign. 7,81% of the respondents acknowledge to having texts in the Academic Spanish Editorial, recognized like predator and the fact that (83.61%) you are ignorant of 199 on the depredatory existence of magazines or editorials in the academic space verified itself of revealing way. Enter the advantages that the respondents expose they find the accreditation of publications (17,77%) and the international visibility (04,44%); And the loss of prestige of authors (35,55%), the loss of the legal authorship of investigation (08,88%), the scientific plagiarism (17,77%) and the loss of the profits were verified like disadvantages (16,00%). The results of the study reflect an approach to the relation that becomes established between corruption and magazines and editorials depredatory, taking into account the ignorance that professionals, the fact that you agree with referent theoreticians and you make it possible to guide actions to prevent the proliferation of the phenomenon in sciences present.

The definition of Quality has evolved in history and approaching it from this perspective implies referring to its five stages in which the gurus made their contributions. To propose considerations for a definition of quality from a healthy approach. The systematic bibliographic review of the definitions of quality, its historical evolution and its application in the context of health systems and services were used. The Pan American Health Organization cites that, to date, although there is a common interpretation of the basic concepts and defining dimensions of quality, there is no universally accepted definition. Thus, Spain, Colombia, and Mexico adopt theirs with elements that coincide such as equity, efficiency, satisfaction, and person-centered care. Definitions of quality and their application in the context of health have evolved and countries have adopted and proposed different statements. Considerations are proposed for a definition of quality from a health approach that among other elements includes providing relevant, timely, safe and efficient services, as well as technological discipline, competition and empowerment, on an axiological basis, of the actors in the processes.
