Experimental Study of High Axial Damping Rubber (HADR) in New Viscoelastic Dampers
Authors: Modhej Ahmad , Zahrai Seyed Mehdi 
Published: January 2019

Abstract
In the last few years, dampers with viscoelastic material as passive energy dissipation devices have been considered, with their dual behavior, in the modern methods of seismic performance-based design. In these new dampers, energy dissipation of viscoelastic material, unlike ordinary viscoelastic dampers obtained by shear strain, is provided by amplified axial strain. Hence, the production of a High Axial Damping Rubber (HADR) is required in these dampers. This article presents the results of experimental work carried out to characterize the mechanical response of a HADR to be used in the design and construction of new viscoelastic dampers for controlling strong vibrations in civil engineering structures. The experimental results showed that the HADR behavior is better than that of styrene butadiene rubber, leading to improved mechanical properties in the range of standard rubber. The hardness, tensile strength, elongation at break, compressive strength, and rate of resilience of this rubber are obtained as, respectively, 60 durometer (shore A), 16.56 MPa, 519 %, 1,730 kPa, and 50 %. Finally, the uniaxial tension and compression data of HADR for its modeling in the finite element program are discussed.

<p>Hiperlipidemia menyebabkan perubahan pada sel imun dan proses penyembuhan luka, sehingga juga meningkatkan kemungkinan untuk terserang periodontitis yang terutama disebabkan oleh bakteri <em>Aggregatibacter actinomycetemcomitans</em> (Aa) atau infeksi lainnya. Asam lemak yang berlebihan dapat menghambat proliferasi sel karena hasil peroksidasi lipid yang bersifat toksik bagi sel. Asam lemak juga ikut mempengaruhi produksi dan modulasi sitokin karena asam lemak dapat menyebabkan reduksi proliferasi limfosit. Diet tinggi lemak telah menyebabkan penurunan jumlah limfosit B. Pada perkembangannya, limfosit B membentuk sel B memori dan sel plasma yang memproduksi antibodi, termasuk IgA. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian diet tinggi lemak dan induksi bakteri Aa terhadap konsentrasi <em>secretory Immunoglobulin </em>A (sIgA) saliva. Sebanyak 28 tikus <em>Rattus norvegicus Strain Wistar</em> dibagi dalam empat kelompok secara random, kelompok K0 diberi pakan standar, kelompok K1 diberi pakan standar kemudian diinduksi bakteri Aa, kelompok K2 diberikan diet tinggi lemak, dan kelompok K3 diberikan diet tinggi lemak kemudian diinduksi bakteri Aa. Pada akhir penelitian seluruh tikus diambil cairan saliva dan diukur konsentrasi sIgA saliva menggunakan metode ELISA. Dari hasil penelitian menunjukkan bahwa terdapat perbedaan yang signifikan konsentrasi sIgA saliva antara kelompok pakan standar tanpa induksi bakteri Aa (K0) dengan kelompok diet tinggi lemak tanpa induksi bakteri Aa (K2) dan antara kelompok pakan standar dengan induksi bakteri Aa (K1) dengan kelompok diet tinggi lemak dengan induksi bakteri Aa (K3)</p><p><strong> </strong></p>
Mobile crowd participation to root small-scale piped water supply systems in India and Bangladesh

Abstract
In the arsenic-contaminated Ganges-Brahmaputra-Meghna Delta in India and Bangladesh, small-scale piped water supply seems a promising way to provide safe drinking water to households in the region. The use of smartphone applications can support monitoring of the system and enhance local engagement and empowerment. In this paper the scope for mobile crowd participation as a research and monitoring tool for piped water supply systems in Bihar, India and in Khulna and Chittagong, Bangladesh is investigated. In these areas, the use of smartphones and internet access are growing rapidly and smartphone applications would enable real-time water quality monitoring, payment of water bills, awareness creation, and a dialogue between the end-user and the water supplier. To identify the relevance and acceptability of piped water supply and smartphone monitoring, four surveys with potential end-users were conducted. Based on these surveys we conclude that in the investigated areas there is a desire for piped water systems, that households already own smartphones with internet access, and that there is an interest in smartphone monitoring. The enabling environment to deploy mobile crowd participation for piped water system monitoring stimulates further research towards an investigation of potential functionalities and the actual development of such an application.

Abstract
Water, sanitation and hygiene (WASH) are vital indicators to healthy living and safe environments for child development. The aim of the study was to determine WASH status and practices in ECD centres located in low socio-economic areas of Nelson Mandela Bay during 2017. This cross-sectional study elicited responses from 46 ECD centres which had a total of 3,254 children and 172 caregivers. A structured questionnaire and visual observation were used. Using core WASH in schools' indicators (WinS) showed that despite improved water sources being available in 91% of the facilities, WinS for hygiene was poor. The study observed that 57% of the respondents had improved toilets accommodating both genders. In 29% of ECD centres, 6–10 children make use of a ‘pottie’ while in 9% of the cases, more than 20 children make use of one ‘pottie’. The use of the bucket system was noted in 22% of the ECD centres. In 79% of the ECD centres, children wash their hands in a communal plastic bowl. Only 11% of the study population washed hands hygienically under a running tap or tippy tap. WASH conditions in the ECD centres in the study area require urgent attention and further investigation for practical solutions.

Abstract
The increase of CO2 in the atmosphere may produce some effects on drinking water because water tends to naturally capture CO2 species. The main purpose was the study of the impact of capture of free CO2 and its transformation to carbonic acid (H2CO3) and bicarbonate ions (HCO−3). The study used a Tillmans equilibrium diagram obtained from the modified Mojmir Mach model as a function of water temperature and considered the effects on anion and cation composition. Three wells located in different zones were selected, with similar characteristics (capture of CO2). Samples were taken in different seasons of the year and the amount of CO2 in the drinking water was calculated. It was found that with increasing concentrations of free CO2 the pH decreases, and this process makes the water acid and susceptible to dissolve some elements (Ca, Na, K, Si) and other species (HCO−3). The capture of CO2 has important effects on the anion and cation composition of drinking water and on the variation of pH by more than one unit, which may affect the health of consumers. The method presented in this study is an excellent user-friendly alternative to determine the impact of natural capture of total CO2 by water.

Abstract
An investigation of the utilization of water quality monitors at water purification plants throughout Japan was conducted via questionnaire from August to October 2015. The number of types of monitors installed at more than one water purification plant was 34. Chlorine, high sensitivity turbidity, pH, and turbidity monitors were (highly) recommended for installation in four water purification processes (rapid sand filtration, chlorination only, slow sand filtration and membrane treatment), except for high sensitivity turbidity of chlorination only. The number of installations of the monitors recommended and their installation points were dependent upon the processes. Highly recommended points of turbidity were raw water and sedimentation points, which were set for (critical) control points in water safety plans. That of high sensitivity turbidity was the rapid sand filtration point for confirmation of Cryptosporidium control. Chlorine monitors were applied for automatic control, regardless of the water purification processes. Some interesting monitors, such as those for musty odor compounds and trihalomethane, were newly developed and utilized. The results of this study showed that water quality monitors were important for water quality management systems based on water safety plans in Japan.

Authors: Faissal Zahrawi , Brian Manzi , Jill Sager 
Published: January 2019

Background:Robotic-guidance for pedicle screws can reportedly increase placement accuracies and surgical efficiencies especially in percutaneous approaches.Objective:The study aimed to compare the accuracy of percutaneous pedicle screw placement and post-operative course of robotic-guidance versus fluoroscopy-guidance performed by a surgeon experienced in performing fluoroscopy-guided MIS spinal fusions.Study Design:This is a retrospective medical chart review of 2 cohorts of consecutive patients operated by the same surgeon.Methods:Medical records of adults suffering from degenerative spine disease treated by percutaneous spinal fusion surgeries with robotic-guidancevs. fluoroscopy-guidance were reviewed. Endpoints included pedicle screw placement accuracy (on post-operative CTs) and surgical complications and revisions.Results:Ninety-nine patients were reviewed in each arm which were similar in demographics and surgical indications. The robotic arm had 5.8 screws per case on average and 6.0 in the control arm (p=0.65). No significant differences were found in postoperative complication rates revision surgeries length of stay duration of surgery screw implantation times blood loss or results of Oswestry Disability Index questionnaires.Post-operative CTs were available for 52 patients (293 screws) in the robotic arm and 70 (421 screws) in the freehand controls. In the robotic arm 100% of screws were found accurately placed within the “safe zone”vs. 410 screws (97.4%) in the control arm (p=0.005). Of 11 breaching screws in the control arm one breached by 6mm but the patient did not suffer from any sequelae (12-month follow-up). The average follow up period was 9.2±4 months in the robotic-guided arm and 10.5±3 in the control arm. There were no significant differences in complications or revisions.Conclusion:A modest yet statistically significant increase in pedicle screw placement accuracy was observed with robotic-guidance compared to freehand. Larger prospective studies are needed to demonstrate differences in clinical outcomes.

Published: January 2019

Introducción: La proporción de adolescentes que han iniciado relaciones sexuales va en aumento y la edad de inicio está disminuyendo, sin embargo, la capacidad para evitar el embarazo no acompaña este comportamiento. En la Jurisdicción Sanitaria No. 1 de Cd. Victoria, Tamaulipas, en el año 2008 se atendieron 15,137 embarazadas, y de estas el 22.0% son menores de 20 años,1 afectándoles de manera importante los planes de vida y futuro de las madres adolescentes. El propósito de esta investigación fue describir las características de la conducta sexual de los adolescentes, variables que se relacionan con el inicio de la actividad sexual, y practicas de riesgo para embarazo. Metodología: Se realizo un estudio observacional, descriptivo, transversal, correlacional.2. En 1212 adolescentes de 12 a 19 años ambos sexos, mediante un muestreo no probabilístico, por disponibilidad. Utilizando un instrumento con un alpha de cronbach de 0.82. Resultados. La mitad de los participantes en el estudio se encuentra en el rango de 15 a 17 años con una media de 16 años. El 97% conoce métodos anticonceptivos, mas no su funcionamiento la información la adquirieron de la escuela y amigos. El 22 % tiene vida sexual activa iniciando entre los 14-15 años, no utilizaron método anticonceptivo por no planear la relación sexual. El 50% tiene más de una pareja, no se encontró asociación entre la edad y el número de parejas ni entre la edad y la última vez en que se tuvo relación sexual. Discusión: Los datos obtenidos sobre conducta sexual no difieren con lo reportado en la revisión de la literatura, la actividad sexual inicia más tempranamente entre los hombres que en las mujeres, el uso de métodos anticonceptivos no es generalizable ni en la primera ni en la última relación sexual. Conclusiones: Un porcentaje alto no tiene conocimiento sobre métodos anticonceptivos y su funcionamiento, considerándose estas variables como riesgo para la presentación de embarazo en la adolescencia.

Published: January 2019

Introducción: El sobrepeso y obesidad infantil son un problema complejo que necesita atención prioritaria en los programas de salud pública para rectificarlo; considerando que los factores desencadenantes son susceptibles de modificación, a través de crear entornos que capaciten y motiven a las personas, familias y comunidades a adoptar conductas positivas en relación a una alimentación saludable y la realización de actividades físicas que permitan mejorar su salud. Desarrollo: En general la investigación sobre obesidad y sobrepeso en México se ha enfocado en estudios epidemiológicos que apuntan a la necesidad de intervenciones en el estilo de vida para reducir esta agresiva epidemia. No obstante, muy pocos estudios han sido capaces de demostrar cuales son las aproximaciones más efectivas para promover cambios en el estilo de vida. Ante tal problemática los profesionales de enfermería, tienen el compromiso y responsabilidad, de crear un entorno que capacite y motive a las personas, familias y las comunidades a adoptar decisiones y conductas positivas en sus estilos de vida, integrando para ello modelos conceptuales y teorías de enfermería. El objetivo de este artículo es presentar una revisión de la literatura acerca del sobrepeso y la obesidad infantil, así mismo hacer énfasis en la necesidad de realizar estudios o investigaciones interventivas de enfermería para contribuir en la disminución de esta epidemia; pretendiendo aportar un marco de referencia para futuras investigaciones. Para ello se realizo una búsqueda y revisión del problema en las principales bases de datos en español (Artemisa, Lilacs y Medline). Conclusiones: el fin es el de aportar un marco de referencia que sirva de apoyo a futuras investigaciones para el desarrollo de intervenciones de enfermería que contribuyan de manera específica a disminuir el sobrepeso y la obesidad.
