El presente proyecto plantea el diseño de un sistema de climatización para un hotel, categoría cuatro estrellas, ubicado en la ciudad de Lima. Dicho hotel posee once pisos y un sótano, dentro de él se encuentran sesenta y ocho habitaciones, una sala de espera, una sala de estar, un bar, un salón principal con dos foyers (vestíbulos), seis salas de reuniones y un comedor con dos halls (vestíbulos). Previamente al desarrollo del proyecto se establecen definiciones relacionadas con los sistemas de aire acondicionado, componentes y accesorios. A su vez se mencionan normas y recomendaciones a seguir para el diseño. El sistema de climatización planteado como solución brindará confort térmico a los huéspedes y personas que hagan uso de las áreas comunes y de servicio del hotel de acuerdo a las recomendaciones del manual ASHRAE HVAC APLICATIONS 2007 Capítulo 5. Este proyecto cont...

El proyecto consiste, que todos los profesores a través de talleres debemos conocer a profundidad los tipos de textos, el plan lector propiamente dicho, tipos de lectura y su importancia, los niveles de lectura entre otros. Lo más importante es conocer y poner en práctica las técnicas básicas de lectura (su propósito, examinar el contenido del texto, preguntarse de lo que leen, buscar el significado de lo que se está leyendo y expresar lo que van leyendo) entre las estrategias tenemos: (Previas a la lectura: El propósito, activación de conocimientos, elaboración de predicciones, formulación de preguntas. Durante la lectura: Determinar las partes relevantes del texto, estrategias como el subrayado, apuntes, elaboración conceptual, elaboración de mapas conceptuales. Luego de la lectura: Identificar ideas principales, elaboración de resúmenes, contestar preguntas, formular co...

Introduction: Mesenteric ischaemia associated with pregnancy is a rare disease with a high mortality rate and its prognosis depends on the time passing between diagnosis and final management. Presentation of case: A 38-year-old Peruvian woman developed intestinal necrosis during week 35 of her pregnancy because of mesenteric ischaemia associated with her pregnancy. Discussion: Given the findings of extensive intestinal necrosis, surgical resection was performed, causing short bowel syndrome. Histopathological analysis confirmed that the immediate cause of the patient’s ischaemia was venous thrombosis associated with her gestation. Conclusion: Acute mesenteric ischaemia should be considered as a possible diagnosis in pregnant woman with risk factors for thrombophilia presenting with abdominal pain.

In this paper, we describe the isolation and biodegradation activity of microorganisms on low density polyethylene. The microorganisms were collected from plastic materials with evidence of deterioration from a landfill. The samples were filtered and selected in a mineral salts medium at pH 5.5 and 7 for bacteria and fungi respectively. Six strains were isolated, identified as Pseudomonas sp. Hyalodendron sp., Penicillium sp. and Rhodotorula sp. Microbial activity was evidenced by changes in the infrared spectrum of polyethylene with respect to the polymer without treatment. Reduction of carbonyl index (83.89% at pH 7 and 4.08% at pH 5.5) and double bonds index (19.77% at pH 7 and 6.47% at pH 5.5) were observed. Finally we determined the percentage of weight lost by the polyethylene subjected to activity of the strains, with a decrease of 5.4% at pH 7 and 4.8% at pH5, 5.

There is a need for new alternative sources of exogenous antifungals to replace those currently used in agriculture. Actinobacteria are gram-positive bacteria with a wide variety of secondary metabolites, which produce around two-thirds of all naturally occurring antibiotics in current clinical use, as well as many anticancer, anthelmintic and antifungal compounds. Consequently, these bacteria are of great importance for agricultural biotechnology, since they can be produced and applied in fields that do not promote resistance among fungi that attack plants. This review presents the research carried out regarding the identification of metabolites with fungal properties, highlighting the main species involved in the production of metabolites that are being used or could be explored in agriculture as bioproducts to promote plant health and sustainability. This review expands knowledge for ...
