Revista de la Universidad Industrial de Santander. Salud , 2011,
Abstract: Introducción: Las infecciones intrahospitalarias constituyen un problema de salud pública mundial, la diseminación de bacterias patógenas a partir del personal de salud, ha sido el enfoque de numerosas investigaciones que buscan mejorar la calidad de vida de los pacientes. Objetivo: Determinar la frecuencia de portadores de Staphylococcus aureus en fosas nasales del personal que labora en las unidades de cuidados intensivos, infectología pediátrica y lactario en un Hospital en Santander. Metodología: Se estudiaron muestras provenientes de fosas nasales de 87 trabajadores del Hospital. Las cepas aisladas se identificaron mediante las pruebas bioquímicas y posteriormente, se determinó el perfil de susceptibilidad ante diferentes antibióticos, se realizó test D a las cepas de S. aureus. Resultados: La frecuencia de portadores de bacterias patógenas fue 41,4%; el patógeno aislado con mayor frecuencia fue S. aureus (72%), donde el porcentaje de S. aureus meticilino-resistentes (SARM) fue de 11,6%, Enterobacter aerogenes (6%), Proteus mirabilis (2,3%), Haemophylus influenzae (1,1%), Citrobacter koseri (1,1%) y Providencia rettgeri (1,1%). Conclusión: S. aureus es el agente aislado con mayor frecuencia de las fosas nasales del personal de salud y la presencia de SARM es preocupante por su resistencia a los antibióticos, lo que dificulta su tratamiento. Este hecho evidencia la necesidad de actuar con un carácter preventivo, en el cual el control de portadores es crítico y debe asociarse con medidas de bioseguridad que establezcan barreras más eficientes, para reducir la diseminación del microorganismo y la ocurrencia de infecciones intrahospitalarias.

Abstract: introduction: nosocomial infections are a public health problem worldwide, its spread start from health personnel carrier of pathogenic bacteria, it has been the focus of a large number of research to improve the quality of life of the patients. objective: to determine the frequency of nasal carriers of staphylococcus aureus in the personnel that works in intensive care units (adults icu and pediatric icu), pediatric infectology and lactary in a hospital in santander. methodology: nasal samples from 87 workers from of the hospital were studied. isolated strains were identified by the corresponding biochemical tests and subsequently determined their susceptibility profiles to different antibiotics and test d for s. aureus. results: the frequency of nasal carriers of pathogenic bacteria was 41.4%; it was found that s. aureus was the most isolated pathogenic microorganism, with a frequency of (72%). the percentage of meticilin resistant s. aureus (mrsa) was 11.6% , enterobacter aerogenes (6%), proteus mirabilis (2.3%); haemophylus influenzae (1.1%); citrobacter koseri (1.1%) and providencia rettgeri (1.1%). conclusion: s. aureus is the most frequently isolated agent in health personnel's nasal nostrils and the presence of mrsa is worrying, additionally, it presents characteristic of resistance to antibiotics, making harder its treatment. this fact evidences the necessity to act with a preventive character, in which the control of carriers is critical and it should be associated with biosecurity measures to establish effective barriers to reduce the dissemination of the microorganism and occurrence of nosocomial infections. salud uis 2011; 43 (2): 111-117
Behavioral Analysis of a Lithium Ion Battery (Li-Ion), a Nickel Metal Hydride Battery (Ni-MH) and a Supercapacitor in an Isolated Photovoltaic Solar System  [PDF]
Laura Milena Cruz Moreno, Diego Fabián Martín Rincón, Johann Alexander Hernández
Energy and Power Engineering (EPE) , 2017, DOI: 10.4236/epe.2017.94020
Abstract: This paper presents experimental research about the behavior of different storage devices such as Li-ion, Ni-MH batteries and supercapacitors when charged by a solar photovoltaic system. Photovoltaic systems work as a variable current source, depending on the solar irradiance. These devices present a different profile charge compared to a constant and controlled charge generated by a traditional charger. For this work, several charging and discharging cycles of batteries and supercapacitors under the same environmental conditions were carried out in order to observe the different characteristics of each technology, and some harmful effects on the storage devices operation such as the memory effect and partial discharges involved in the proper functioning of the solar photovoltaic system.

Abstract: using a qualitative and interpretative approach, the perceptions and beliefs related to lifestyle choices of a group of sufferers of acute myocardial infarctions are analyzed and described. the study tries to find, from the subject itself, the situations that make him or her pick up a habit. the sample was constituted by the information given by seven users of the health services of the national university, who were approached at two different moments with non-structured interviews, justified by the principle of saturation. from the analysis, it was possible to build six categories and subcategories that allowed for a description of the studied incident. amongst these categories, are: identity, impact of the experience, taste, elements behind change, human relationships and health strategies. these categories were later analyzed through the lens of four existential elements, presented by the phenomenological theory: experienced body, experienced space, experienced period and experienced human relationships. the findings allows for advances in the comprehension of the self, to which is recommended a change of habits, with a renewed vision of the topic. as such, the construction and retrieval of the cultural knowledge of the health-disease process from the point of view of those same social subjects is attempted. this also brings the reanalysis, from different standpoints, of several health promotion and disease prevention approaches that provide better results.
