The retraction affects the setting process and the useful life of the concrete with the appearance of fissures; in last year's studies and methods have been generated to mitigate and control it with the use of different products and applications. The development of road infrastructure with the use of concrete as a rolling folder, requires methods to guarantee the durability and reduce the effects of the efforts incorporated by the use, climatic conditions, support base and restrictions of movement of the structure. To evaluate the effects of recycled synthetic polypropylene fibers in plastic retraction tests (ASTM C 1579), 3 mix designs were prepared with different ratios 58 gr., 116 gr., and 176 gr. of recycled and virgin synthetic fibers; the most significant and positive result to reduce fissures without affecting the resistance of concrete by bending and compression, was 0.50 mm with...

The aim of the study was to inactivate pathogenic microorganisms through the composting process for 120 hours using residues of organic compounds in two proportions: C/N 25 composed of 25.31, 40.42 and 34.27% and C/N 35 for 44.61, 12.90 and 42.50% of bean straw, fresh sorghum forage and dry chicken manure, respectively. The variables analysed were temperature, microbial load (mesophilic aerobics, total and faecal coliforms) and reduction of Escherichia coli and Salmonella Typhimurium, artificially inoculated in three levels of the compost piles. The C/N 35 treatment reached the highest temperature and inactivation of the pathogenic microorganisms evaluated during the thermophilic phase of composting. The temperatures reached were not homogeneous between the levels of the piles, being lower in the upper level (p<0.000). This study suggests the implementation of composting as an efficie...

The main purpose of the current investigation was to analyse the relationships that may exist between organizational climate and the culture of patient safety in a public hospital of Lima with the goal of generating viable alternatives that allow a significant improvement of the quality of attention to the patients that concur there. In the development of the current investigation were used the Scale of Organizational Climate (ECDO) of Acero Yusset and the Hospital Survey on Patient Safety in its Spanish version (Madrid: Ministry of Health and Consumption). The statistical analyses the tests were submitted to indicate us that the instruments are valid and reliable. These tests were applied to a sample of 155 people between doctors and nurses. The statistical results show us that the organizational climate and the culture of patient safety are significantly related; moreover, it was found...

As the knowledge management has acquired a significant importance as a change and development factor in all the work of the society, it is vital to create a culture where information and knowledge are valued, shared, managed and used effective and efficiently. Under these considerations, the current investigation is made, having as main objective to establish whether the knowledge management has influence on the professional skills in a sample of teachers from an Educative Network of Lima Metropolitana. A correlational causal design was used with a sample of 217 to whom two instruments of evaluation were applied: the Questionnaire of Knowledge Management of Liliana Pedraja and the Inventory of Teaching skills of Úrsula Romaní. The analyses the instruments were submitted to determined consistent levels of validity and reliability. The results show that the Knowledge Management has signi...

El propósito fundamental de la presente investigación fue analizar las posibles relaciones entre el clima organizacional y la cultura de seguridad del paciente que existe en un hospital público de Lima, con la finalidad de generar alternativas viables que permitan mejorar significativamente la calidad de la atención a los pacientes que concurren allí. En el desarrollo de la presente investigación se utilizó la Escala de Clima Organizacional (EDCO) de Acero Yusset y el cuestionario sobre seguridad de los pacientes: versión española del hospital Survey on Patient Safety. Madrid: Ministerio de Sanidad y Consumo. Los análisis estadísticos a los que fueron sometidas las pruebas nos indican que los instrumentos son válidos y confiables. Estas pruebas fueron aplicadas a una muestra de 155 personas, entre médicos y enfermeras. Los resultados estadísticos nos indican que el clima or...

In the world there are adverse climates, climates that hinder the good construction and paving of roads, generating insecurity among the locals and visitors. This over time affects the economy of a country, as a road boosts tourism, transport and commerce. Therefore, a mixture was designed to mitigate a problem in the placement of hot asphalt mixture at temperatures below zero degrees Celsius. That is, a conventional mix design was proposed, but with different types of filler (lime, Portland cement type I and silica) tested with the Marshall and Lottman method which are governed according to the EG-2013 standards [1] and parameters established in the Asphalt Institute [2]. To find the optimum, it was tested with 5.0%, 5.5% 6.0% and 6.5% asphalt cement. Then with the results obtained a comparative analysis was performed. Finally, specimens without any additives were made, the specimens on...

According to working hypothesis from this further research, the aggressor behavior predisposed factors (husband or partner),this is, his tendency to exert physical and psychological violence against his partner and children, It’s originated in a violent environment in which the aggressor developed his childhood associated to lack of affection and material things. The same type of predisposed factors, also influences in the perceptions and interpretations of the attacked woman, in respect of the familiar violence, in what she and her children are victims.
