Published: June 2017

Los drenajes ácidos de mina (DAM) son vertimientos con bajo pH, alta concentración de metales y sulfato. Son considerados el mayor problema ambiental de la industria minera y prevenir su formación es la mejor alternativa ambiental y económica. En este estudio, se evaluó el compost de champiñón como enmienda de carbono orgánico para prevenir la formación de DAM. Se construyeron tres celdas en tubos de PVC (2,4 L), llenas con 300 g de mezcla de compost de champiñón y estéril de carbón en diferentes proporciones (40:60, 25:70, 60:40) y 400 mL de agua (18,5Ω). Los cambios químicos en el lixiviado, así como la actividad microbiana en las mezclas fueron monitoreados durante 6 semanas. En los lixiviados el oxígeno disuelto (< 2,0 mg L-1) y potencial de óxido reducción (< -100 mV) disminuyeron, mientras el pH (> 6,5) y la alcalinidad (> 1.500 mg CaCO3 L-1) incrementaron. Además, todas las mezclas fueron eficientes en precipitar los metales (Fe2+ > 95%; Mn2+ > 96%; Zn2+ > 52%) y remover sulfato (> 50%). Sin embargo, en la celda que contenía una proporción de compost y estéril de 25:75 se observó una producción significativa de sulfuro y una mayor actividad microbiana, indicando la presencia de bacterias sulfato-reductoras. Los resultados muestran que el compost de champiñón puede ser utilizado como enmienda orgánica de carbón para contrarrestar la formación de DAM y que la mezcla 25:75 puede ser una opción promisoria para usar en campo en el Distrito minero de Zipaquirá (Colombia).
Atividade bactericida de três desinfetantes sobre Staphylococcus aureus resistentes a meticilina (MRSA)
Authors: Marchionatti Avancini Cesar Augusto , Corrêa Both Jane Mari 
Published: June 2017

Justificativa e Objetivos: os Staphylococcus aureus resistentes a meticilina (MRSA) estão envolvidos em infecções nosocomiais (HA-MRSA), em infecções adquiridas na comunidade (CA-MRSA), nos animais de companhia e em animais para produção de alimentos (LA-MRSA). Na conduta para o controle da sua transmissão, a ação sobre os agentes causais presentes nas superfícies dos ambientes exige atenção, sendo decisiva a escolha de desinfetantes e anti-sépticos. O objetivo deste estudo foi avaliar a atividade bactericida, sobre 21 isolados MRSA e bactéria controle, dos compostos químicos hipoclorito de sódio (HS), iodofór (I) e quaternário de amônio (QAC - cloreto de cetil trimetilamônio), usados rotineiramente em ambientes hospitalares e igualmente nos de produção e saúde animal, bem como testar hipótese da possibilidade de resistência cruzada entre antibióticos e desinfetantes. Métodos: pelo teste de suspensão, usando densidade populacional inicial dos inóculos em 107UFC/mL, avaliou-se a atividade bactericida de quatro diluições sucessivas dos desinfetantes, nos tempos de contato de cinco, 15 e 30 minutos. Resultados: observou-se que os desinfetantes nas concentrações HS 25 ppm, I 12,5 ppm e QAC 125 ppm, aos cinco minutos de contato, foram suficientes para inativar a bactéria de referência S. aureus ATCC 6538 e todos os MRSA. Conclusão: controlados os fatores que interferem na eficácia dos desinfetantes, o hipoclorito de sódio, o iodofor e o quaternário de amônio são adequados para controlar os MRSA nas fontes de infecção, e que nos isolados resistentes ao antibiótico meticilina não foi observada relação de resistência com os estes compostos químicos.

Diagnostic value OF oct-angiography AND regional hemodynamic assesSment in patients with retinal vein occlusion
Authors: Tultseva Svetlana N. , Astakhov Yury S. , Rukhovets Aleksey G. , Titarenko Aleksandra I. 
Published: June 2017

Introduction. Ischemic maculopathy is the main cause of irreversible vision loss due to retinal vein occlusion (RVO). Fluorescein angiography (FA), which is the gold standard for evaluating retinal capillary plexuses, does not allow for the visualization of separate intraretinal capillary networks. Optical coherence tomography angiography (OCT-angiography) enables the possible visualization of four capillary plexi and allows for the quantitative analysis of microcirculation to quantitatively estimate capillary network density and non-perfusion areas.
Aim. To investigate microcirculation changes using OCT-angiography data and to compare the changes with opthalmoplethysmography indices in patients with RVO.
Material and methods. The study included 12 patients with RVO. In all patients, a routine ophthalmic examination was performed, and ocular blood flow was estimated using FA, OCT-angiography, and ophthalmoplethysmography.
Results. Ischemia in the macular area was detected in four patients (25%) according to FA results, and in eight (67%) accor ding to OCT-angiography data. Compared with the unaffected eye, significant decrease in the density of both superficial and deep capillary plexuses as well as a decrease in flow area and enlargement of foveal avascular zone were observed. A significant close direct correlation was established between capillary density in the superficial capillary plexus (r 0.8) and the deep capillary plexus (r 0.7), choroidal thickness, and opthalmoplethysmography indices (r 0.6).
Conclusion. Compared with FA, OCT-angiography is a more sensitive method to detect macular capillary perfusion. In cases with RVO, the combination of the above mentioned methods with ophthalmoplethysmography allows for the comprehensive evaluation of regional hemodynamics.

Today, many of the resin parts of automobiles are molded using the injection molding technique with high productivity. In the case of a large part, for which a mold clamping force of more than 2,000 t is needed, it is common that a piece of the part is manufactured with one metal mold and the parts with bilateral symmetry are manufactured simultaneously with a separate one. This development focuses on the advantage that productivity could be enhanced and the cost for a metal mold could be reduced by utilizing the space in the mold cavity for a large part and making another metal mold for a small part. To mold a large and small part with a large volume ratio simultaneously by using one metal mold, the fluid distribution of molten resin suitable for the volumes of both parts is necessary. Without realizing the associated fluid distribution molding defects, such as short, sink, or the like, would occur. In the case of the large part, such as a bumper, molten resin flows from the injection unit through a hot runner unit within the metal mold and subsequently, each gate into each product. To distribute the appropriate amount of resin to the large and small parts through a hot runner, the molding technique involves distribution of the fluid to each gate with an appropriate balance by controlling flow through the valve of a hot runner; this paper discusses the aforementioned technique.
Because the energy and the power of the molding machine to melt and inject the resin can be reduced by molding two deferent parts with one die, this family mold can contribute to Green production.
O agir democrático numa era de redes digitais
Authors: Coleman Stephen 
Published: June 2017

<p><strong>RESUMO</strong></p><p><strong></strong>A política contemporânea possui uma qualidade transitória e indeterminada, pairando de forma inquieta entre o centralizado e o em rede, o nacional e o global, o gerenciado e o populista, o analógico e o digital. Práticas políticas antes tomadas como certas começaram a parecer instáveis e modos emergentes de articulação política estão desestabilizando complacências institucionais. Ao longo do século XX, a consolidação de democracias políticas gerou abordagens de rotina à produção, ao processamento e à comunicação de mensagens políticas. Este sistema de comunicação política resultou em relações previsíveis entre elites políticas, mediadores jornalísticos e cidadãos. Como espero ter deixado claro nesta palestra, seria ingênuo supor que simplesmente mover a comunicação política online irá enriquecer ou degradar as vozes dos cidadãos democráticos. O antigo debate entre o bem e o mal da internet é despropositado e redundante. Porém, se a pressão democrática popular pelo tipo de construção de capacidade cívica que eu elenquei nesta palestra ganhar tração, tecnologias digitais, espaços e códigos podem, realmente, ter um papel significativo em facilitar práticas conducentes a uma democracia mais inclusiva, respeitosa e deliberativa. </p><p> </p><p class="p3"><strong>ABSTRACT</strong></p><p class="p3">Contemporary politics has a transitional and indeterminate quality, hovering uneasily between, the centralised and the networked, the national and the global, the managed and the populist and the analogue and the digital. Once taken-for-granted political practices have begun to seem unstable and emergent modes of political articulation are unsettling institutional complacencies. During the course of the twentieth century the consolidation of political democracies generated routine approaches to producing, processing, and communicating political messages. This political communication system resulted in predictable relations between political elites, journalistic mediators and citizens. As I hope I have made clear in this lecture, it would be naïve to assume that simply moving political communication online will either enrich or degrade the voices of democratic citizens. The old debate between Internet-Good and Internet-Bad is pointless and redundant. But if popular democratic pressure for the kind of civic capability-building that I have outlined in this lecture were to gain traction, digital technologies, spaces and codes might indeed play a significant role in facilitating practices conducive to a more inclusive, respectful and deliberative democracy.</p>

OBJECTIVE
We aimed to investigate the differences in clinical characteristics and pharmacological treatment associated with the presence of diabetes in a large cohort of patients with dementia.

RESEARCH DESIGN AND METHODS
A cross-sectional registry-based study was conducted using data from the Swedish Dementia Registry (SveDem). Data on dementia diagnosis, dementia type, and demographic determinants were extracted from SveDem. Data from the Swedish Patient Register and Prescribed Drug Register were combined for the diagnosis of diabetes. Data on antidiabetic, dementia, cardiovascular, and psychotropic medications were extracted from the Swedish Prescribed Drug Register. Logistic regression was used to determine whether the variables were associated with diabetes after adjustment for confounders. In total, 29,630 patients were included in the study, and 4,881 (16.5%) of them received a diagnosis of diabetes.

RESULTS
In the fully adjusted model, diabetes was associated with lower age at dementia diagnosis (odds ratio [OR] 0.97 [99% CI 0.97–0.98]), male sex (1.41 [1.27–1.55]), vascular dementia (1.17 [1.01–1.36]), and mixed dementia (1.21 [1.06–1.39]). Dementia with Lewy bodies (0.64 [0.44–0.94]), Parkinson disease dementia (0.46 [0.28–0.75]), and treatment with antidepressants (0.85 [0.77–0.95]) were less common among patients with diabetes. Patients with diabetes who had Alzheimer disease obtained significantly less treatment with cholinesterase inhibitors (0.78 [0.63–0.95]) and memantine (0.68 [0.54–0.85]).

CONCLUSIONS
Patients with diabetes were younger at dementia diagnosis and obtained less dementia medication for Alzheimer disease, suggesting less optimal dementia treatment. Future research should evaluate survival and differences in metabolic profile in patients with diabetes and different dementia disorders.

MODELO DE GESTIÓN DE MANEJO COSTERO INTEGRADO EN EL ECUADOR.
Authors: Soria Freire Vladimir José 
Published: June 2017

Las zonas costeras son espacios en los que se desarrollan importantes actividades económicas que generan presiones e impactos sobre el medio ambiente, lo cual requiere respuestas por parte del sector público y privado, para garantizar la sostenibilidad en la gestión de sus recursos. El manejo costero integrado, como propuesta de gobernanza, incluye dos caminos: fortalecimiento institucional y participación ciudadana. El presente artículo propone un modelo de gestión a escala local, basado en tres ejes: el fortalecimiento de las capacidades institucionales de los gobiernos locales, el ordenamiento territorial para una adecuada determinación y delimitación de las competencias en materia ambiental costera; y, la participación ciudadana a nivel del régimen de las comunas, en coordinación con los distintos niveles de gobierno. Un total de 26 comunas costeras son estudiadas y se presentan resultados para evaluar el grado de cumplimiento de los objetivos de desarrollo.

ABSTRACT

Coastal areas are spaces that develop economic activities that generate significant pressures and impacts on the environment, which requires a response from the public and private sector to ensure sustainability in the management of their resources. Integrated coastal management and governance approach includes two avenues: strengthening of institutional bodies and citizen participation. This article proposes a model of local management based on three pillars: the strengthening the institutional capacity of local governments, the proper land outlining and delimitation, and the determination of the competences in the coastal environmental, and citizen participation in the community system in coordination with the various levels of government. A total of 26 coastal communities are studied and the results are presented to measure the degree of fulfillment of the development goals.
