En la presente investigación se realizó la propuesta para el diseño de un humedal de flujo subsuperficial empleando Bambusa sp en el tratamiento de aguas residuales domésticas, generadas por la finca el Recreo en Tauramena. La investigación se llevó a través de un alcance descriptivo y alcance cuantitativo, llevando en primera instancia a la caracterización física, química y microbiológica del agua residual doméstica sin tratamiento mediante el análisis de 19 parámetros de calidad; luego de la determinación de la calidad del efluente se comenzó con el diseño y construcción de la prueba piloto con Bambusa sp como macrófita experimental y una segunda prueba con Heliconia psittacorum siendo esta la <p>macrófita control. Al agua resultante de las dos pruebas piloto se les realizó las mismas pruebas de calidad que al agua del efluente sin ningún tratamiento, mediante un análisis in situ e in vitro, este último dividido en dos grupos siendo los parámetros más relevantes DBO, DQO, grasas y aceites y fosforo analizados en el laboratorio Biopolab, los demás parámetros en los laboratorios de la Universidad El Bosque. Los resultados de la demanda química de oxígeno para aguas residuales domésticas de 768 mg / L de O2 mostraron una disminución en el parámetro en la prueba piloto utilizando Bambusa sp a 288 mg / L de O2 e incluso más para Heliconia psittacorum De 44,8 mg / L de O2, La demanda bioquímica de oxígeno (DBO) para las aguas residuales no tratadas fue de 446 mg / L de O2, seguida de Bambusa sp correspondiente a 186 mg / L de O2 y la planta de control de 24 mg / L de O2; el total de sólidos en suspensión para aguas residuales domésticas fue de 1407,5 mg / L, la prueba piloto de Bambusa sp de 557,5 mg / L y la prueba piloto Heliconia psittacorum de 516,25 mg / L; (N-NO2-), color, dureza total, alcalinidad total, salinidad y pH (incremento positivo) de los 19 parámetros analizados.<br />Según los resultados obtenidos en los diferentes análisis se concluye que la eficacia de la Bambusa sp en el tratamiento de aguas residuales domésticas es de un 73% frente a un 79% de la Heliconia psittacorum, siendo esta última más eficiente. Es posible presentar los humedales artificiales como una opción viable para el tratamiento complementario de aguas residuales domésticas, reduciendo los efectos adversos de los vertimientos sobre los medios receptores. Además de ofrecer la opción de reutilizar el efluente tratado como agua de riego para plantas de jardín haciendo de la finca El Recreo sostenible y sustentable en cuanto a su economía generando menor impacto ambiental.</p>

<p>Research to utilize natural polymers continues to be driven primarily by utilization as an environmental friendly energy-generating and storage material. The high porosity makes cellulose acetate (CA) a good candidate as a dielectric material as the basis of the supercapacitor device. Various dopants and compositions have been widely used, but the nano size morphological differences of the same material are rarely reported. Two types of ZnO are prepared, i.e., nanoparticles and nanorods deposited with CA and deposited on ITO glass substrate. The CA-ZnO / ITO composite film was fabricated through spin coating technique. This study focused on ZnO morphological difference on the microstructure and the dielectricity of CA-ZnO /ITO composite films. The morphology of nanoparticles and nanorods of ZnO were analyzed more detail with respect to its microstructure and dielectric properties. It is revealed that the change of ZnO morphology from nanoparticles to nanorod increase the capacitance and dielectric constant significantly from the order of the nano to the micro and decrease the dielectric loss. The dielectric constant of CA-ZnONP/ITO and CA-ZnONR/ITO are respectively of 2569 and 97159 at 100 Hz. The capacitance and dielectric loss of CA-ZnONP/ITO and CA-ZnONR/ITO reach to 69.809 nF; 678 and 2,15765 µF; 13,23 respectively. </p>

Authors: Lima Bruno Alves , Alves Helena 
Published: July 2018

Introdução: Implementadas em 2007 pelo Despacho nº 6357, as regras de alocação de rins de dador cadáver procuram distribuir de forma equitativa um bem escasso da comunidade destinado a doentes que com ele possam ver melhorada a sua sobrevivência e qualidade de vida. Tal como exposto no referido despacho estas regras devem ser atualizadas sempre que o estado da arte o recomendar. O objetivo deste trabalho é o de avaliar e comparar três modelos de alocação de rins de dador cadáver: critérios de pontuação das regras do despacho nº 6537/2007 (modelo 1); modelo semelhante ao anterior mas com menor pontuação para o tempo de diálise (modelo 2); e um modelo adaptado do sistema de alocação por cores previamente proposto (modelo 3).Material e Métodos: Para efeitos desta análise foram gerados dados para 70 dadores tendo em conta a informação publicada relativa à distribuição de grupo sanguíneo e de frequências alélicas e haplotípicas do sistema de antigénios leucocitários humanos de dadores voluntários portugueses. Foram também gerados dados para uma lista de espera simulada de 500 candidatos a primeiro transplante renal.Resultados: Para a frequência do número de incompatibilidades de antigénios leucocitários humanos dos candidatos selecionados por cada modelo verifica-se que há menos candidatos no modelo 3 com mais de 3 incompatibilidades de antigénios leucocitários humanos (39,3%) do que no modelo 1 (57,1%, p < 0,01).Discussão: Em comparação com as regras adaptadas do despacho nº 6537/2007 (modelo 1) para alocação de rins, o modelo 3 seleciona candidatos com menor número de incompatibilidades de antigénios leucocitários humanos sem penalizar os candidatos com um maior tempo de diálise.Conclusão: A análise e discussão das melhores regras a utilizar na alocação de um bem tão escasso como os órgãos de dador cadáver deve ser um processo contínuo e adaptável à evolução e mutação inerentes à lista de espera de candidatos a transplante.

Chemotherapy/radiation in cancer patients causes cancer-related fatigue (CRF). It affects the level of independence of patients’ activity of daily living (ADL). Thus, the responsibility of caregivers will be higher and it impacts on caregiver stress level. The aim of this study was to prove the effects of CRF on independence level of cancer patients and caregivers’ stress level. This study used analytical associative design. The population was cancer patients and caregivers in Yayasan Kanker Indonesia in East Java. The number of samples were 30 cancer patients and 30 caregivers, taken by total sampling method. The assessment was based on instrument brief fatigue questionnaire, activity of daily living based on Katz, and caregiver stress on self assessment questionnaire. The effects of CRF on the level of independence were indicated by p=0.000, and the levels of independence of the caregiver stress level were indicated by p=0.000. As a conclusion, the failure of muscle function due to CRF can affect the independence of patient’s ADL fulfilling, so caregiver should take much time to treat patient and it affects on the increased stress level of caregiver.

Accurate determination of age is important in the legal process; when a person’s age is unknown or must be authenticated, a forensic age identification method must be applied. One of such methods is to assess the epiphyseal closure on the bone through radiological examination. The main problem associated with the use of this method is the relevance of the reference population provided because epiphyseal closure is influenced by genetics and nutrition. This method needs data to represent each population. Radiological examination of elbow bones of 30 male patients aged 11-30 years and 18 female patients aged 14-28 years in Dr. Soetomo Hospital, Surabaya from January to April 2016 was carried out to determine the time of epiphyseal closure of the radius and ulna distal section. This was cross-sectional descriptive study. In conclusion, epiphyseal closure of proximal radius and ulna is complete at age 16 in males and 14 in females.

Paradigm shift in education has made significant change in the roles of teacher and student in teaching and learning process. In the new paradigm the student become the axis of teaching and learning process. The student makes the choice in learning objective, learning materials, and learning resources based on his/her learning style. The teacher acts more as a learning designer, learning manager, and tutor. The learning theory development tends to provide the learner with learning skills to enable them to be independent learners to life-long learning. However, the learning theories are mostly discussed in the formal eduacation situation, though the theories are also apllicable for nonformal education. This article discusses how the current learning theories can be implemented in nonformal education. The discussion is limited on the application of learning resources development in early childhood education and learning community centers. The discussion ends with a strong conclusion that resources based learning theory are potential and need to apply in nonformal education under a condition that there should be some changes in the roles of teachers/instructors, learners, and the nonformal institution.
