Abstract: O presente trabalho visa descrever os passos para desenvolvimento de um curso e sua estrutura em ambiente virtual de aprendizagem Moodle. Para tanto, a pesquisa consistiu na aplica o de conteúdos de enfermagem para oferecimento de curso online em workshop internacional para grupo de estudantes de gradua o e licenciatura em enfermagem do Brasil e de Portugal. Durante a pesquisa foram registradas etapas distintas, desde o planejamento do curso passando pela constru o e transforma o dos conteúdos, até a disponibiliza o aos estudantes. As atividades interativas e conteúdos foram elaborados pelos professores com participa o de equipe técnica. No trabalho s o apresentados procedimentos específicos e papéis a serem desempenhados por professores, especialistas, estudantes e técnicos. Os resultados do desenvolvimento e oferecimento do curso online apontaram alguns aspectos a serem aperfei oados no processo de trabalho, no formato dos conteúdos e na utiliza o das ferramentas. La finalidad de este trabajo es describir los pasos para desarrollo de un curso y su estructura en ambiente virtual de aprendizaje Moodle. Para eso, la investigación comprendió la aplicación de contenidos de enfermería para ofrecimiento de curso online en oficina internacional para grupo de alumnos de pregrado y licenciatura en enfermería de Brasil y Portugal. Durante la investigación fueron registradas etapas distintas, desde la planificación del curso, incluyendo la construcción y transformación de contenidos, hasta su disponibilidad para los alumnos. Las actividades interactivas y contenidos fueron elaborados por los profesores con participación de equipo técnico. En el trabajo son presentados procedimientos y papeles que deben desempe ar los profesores, especialistas, alumnos y técnicos. Los resultados del desarrollo y ofrecimiento del curso online indicaron algunos aspectos que se debe perfeccionar en el proceso de trabajo, formato de los contenidos y en la utilización de las herramientas. This study describes the steps for developing a course and its structure in the Virtual Learning Environment Moodle. It consisted of an application of nursing content offered in an online course included in an international workshop directed to a group of nursing students from a bachelor and a teaching diploma program in Brazil and Portugal. Distinct stages were identified during the study: planning, construction and transformation of content as well as availability of such content to students. The interactive activities and context were developed by professors with the participation of the tec

State Variable Model for Considering the Parasitic Inductor Resistance on the Open Loop Performance of DC to DC Converters  [PDF]
Carlos Alberto Lozano Espinosa
Journal of Computer and Communications (JCC) , 2014, DOI: 10.4236/jcc.2014.213006
Abstract:

This paper shows DC and small-signal circuit models for the PWM DC to DC buck, boost and back/ boost converters with the equivalent series resistance of the inductor. The DC voltage transfer function and the efficiency of the converter are derived from the DC model. Small-signal open-loop characteristics are derived from the small-signal model based on a state variable model. A design example proves the performance of the circuit and verification of the model.

Treatises and Ars construendi: Teaching’s Method Theory and Practice of Critical History’s Application Based on Teacher-Student Relationships  [PDF]
Carlos Alberto Cacciavillani, Simona Rinaldi
Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.49016
Abstract: The topic of this lecture is the results’ description obtained during many years of teaching. We shall illustrate how students use the same analytical techniques to study two different aspects: 1) Architectural Treatises are first studied separately and then in a comparative way. The purpose of this graphic analysis is to reach a new interpretation of them through the realization of original graphics; 2) The Roman Ars construendi: architectural techniques and buildings’ typologies used by the Romans are investigated in the archaeological sites, where the reading of buildings’ stratification in different historical periods becomes an important teaching tool.
Avalia??o bioquímica e ultraestrutural da intera??o de imunocomplexos de IgG com leucócitos polimorfonucleares: efeito de antioxidantes naturais

Abstract: the generation of reactive oxygen species (eros) by polymorphonuclear leukocytes (lpmns) during phagocytosis plays a key role in the organism defense against invading microorganisms. however, in some diseases the immune complexes deposition occurs, that causes an increase in the production and release of eros. consequently, the host tissue is damaged. in this work we studied the effect of natural compounds (quercetin and 7-allyloxycoumarin) on eros generation by rabbit (lpmns) stimulated with immunecomplexes (ic) of chicken egg albumin (antigen) and class g immuneglobulins (igg) - icigg. the eros production was measured by chemiluminescence assay (ql) enhanced by luminol (ql lum) or by lucigenin (ql luc). the interaction between icigg (conjugated with colloidal gold) e lpmns, mediated by fcg membrane receptor, was observed by transmission electron microscopy. the results indicated that the studied compounds inhibited ql lum and ql luc. they also suggest that such effects are not related to phagocytosis inhibition, as observed by the electron microscopy assay.
Tratamento intra-operatório da fibrila o atrial cr nica com ultra-som
BRICK Alexandre Visconti,SEIXAS Tamer,PORTILHO Carlos,PERES Ayrton Klier
Revista Brasileira de Cirurgia Cardiovascular , 2001,
Abstract: INTRODU O: A compartimenta o atrial intra-operatória foi realizada em 27 pacientes, utilizando ultra-som (US). Esta forma de energia parece ser mais efetiva na cria o de linhas de les o nos átrios, mais profundas e mais uniformes, sem causar carboniza o. CASUíSTICA E MéTODOS: Foram operados, de mar o de 1999 e junho de 2000, 27 pacientes, com média de idade de 36 anos. Destes, 19 eram mulheres, 23 eram portadores de doen a reumática na valva mitral (5 eram casos de reopera o), 2 apresentavam insuficiência mitral por degenera o mixomatosa, 1 era portador de cardiopatia congênita e 1 apresentava fibrila o atrial isolada. RESULTADOS: Os tempos operatórios foram em média de 166,6 minutos para a opera o, 69,2 minutos de circula o extracorpórea, 39,7 minutos de parada cardíaca pelo pin amento da aorta, e 12,5 minutos e 14 minutos para efetuar as linhas de abla o nos átrios direito e esquerdo, respectivamente. Houve revers o ao ritmo sinusal em 24 pacientes, durante o ato operatório. Em 2 pacientes a revers o n o foi obtida e 1 paciente apresentou bloqueio atrioventricular transitório, n o havendo uma explica o plausível para os 2 casos de n o revers o, pois os 2 pacientes foram submetidos a opera o para corre o da valvopatia pela primeira vez e o átrio n o estava muito dilatado. Foram observadas duas recorrências e dois óbitos ocorreram por insuficiência respiratória e choque cardiogênico, no pós-operatório imediato, sem rela o com a técnica. A porcentagem de sucesso foi de 81,4%, por ocasi o da alta hospitalar. Todos os pacientes fizeram uso de verapamil ou amiodarona, para remodela o atrial. CONCLUS O: O uso do ultra-som, para criar linhas de abla o no átrio, durante a cirurgia cardíaca, é efetivo, modifica e torna mais fácil o procedimento do labirinto, causa menos dano aos tecidos, diminui o tempo de cirurgia e as possibilidades de complica es pós-operatórias.
