MICROCLINIC INTERNATIONAL SOCIAL NETWORK BEHAVIORAL HEALTH INTERVENTION IN MONGOLIA
Diabetes is a chronic communicable disease that is projected by 2030 to be the seventh leading cause of death worldwide. In Mongolia diabetes and cardiovascular disease are the number one reason for disability-adjusted life years and trends of diabetes is starting to be observed in the poorer populations. Diabetes in countries like Mongolia are extremely costly to treat using insulin, costing 1,466.85 USD. Mongolia has a total population of 2,959,000 and half of its population resides in the capital city of Ulaanbaatar. 60% of residents in capital live in an area called the Ger District that surrounds the urbanized areas. The ger district lacks access to water, electricity and has an unemployment rate of 60%. Based on the KAPs survey the average Mongolian does not know what diabetes is or how it can be prevented. To help address the increasing prevalence of diabetes and lack of knowledge in Mongolia the Flourishing Futures NGO community centers is proposing the implementation of the Microclinic International Social Network Behavioral Health Intervention program. his program uses social relationships to prevent and manage diseases like diabetes, obesity, and HIV/ Aids. A Microclinic itself is not a solid building or a particular place but is made up of a person’s social network or family. Research has demonstrated that this program effectively reduces blood glucose levels and has been used in several low-income countries like Jordan and Kenya. Through implementing this program, Flourishing Futures aims to reduce risk factors associated with diabetes and increase knowledge on what diabetes is and how it can be prevented in Ulaanbaatar, Mongolia
Oscillatory behaviour in Type IA FBG: Ruling out chemical complexity
© 2015 SPIE. Type IA FBG are regenerated gratings that appear in hydrogenated germanosilicate fibre of all types during prolonged UV exposure. The gratings are characterised by a large Bragg wavelength shift and a concomitant increase in the mean fibre core index. Modulated index changes are complex by comparison and significantly weaker, often characterised by oscillatory growth behaviour. Low thermal stability of Type IA gratings suggests a possible chemical role similar to thermally processed optical fibres where autocatalysis has been observed. We show that GeOH and SiOH formation are not out-of-phase and follow each other, with no evidence of autocatalysis, ruling out a chemical origin
Evidence of chemical complexity and laser-driven autocatalysis in type IA FBGs
© OSA 2016. We observe the first chemical complexity for Type IA FBG growth under prolonged UV laser exposure. Out-of-phase oscillatory behaviour in GeOH/SiOH formation provides evidence of laser-driven autocatalysis and chemical origins for grating formation
The impact of hydrogenation conditions on the temperature and strain discrimination of Type i and Type IA Bragg grating sensors
We report experimental findings for tailoring the temperature and strain coefficients of Type I and Type IA fibre Bragg gratings by influencing the photosensitivity presensitisation of the host optical fibre. It is shown that by controlling the level of hydrogen saturation, via hot and cold hydrogenation, it is possible to produce gratings with lower thermal coefficients. Furthermore, there is a larger difference between the Type I and Type IA thermal coefficients and a significant improvement in the matrix condition number, which impacts the ability to recover accurate temperature and strain data using the Type1-1A dual grating sensor
Embedding low loss polymer optical fibre Bragg gratings:two different approaches
In this paper, we present two different ways to embed polymer fibre Bragg gratings (FBGs) into polymer matrices. In the first experiment, we embedded the FBG into a 3D printed polymer structure, whereas in the second experiment, the coating was polymerized around the fibre. In both cases, the response of the grating was unchanged, without any loss or distortion of the FBG signal compared with the bare fibre response. The design of the polymer coating was optimised for the measurement of a single measurand. We highlighted two possible applications: surface bend deformation monitoring and improved-sensitivity temperature sensing
High Performance Inverted Organic Photovoltaics Without Hole Selective Contact
A detailed investigation of the functionality of inverted organic
photovoltaics (OPVs) using bare Ag contacts as top electrode is presented. The
inverted OPVs without hole transporting layer (HTL) exhibit a significant gain
in hole carrier selectivity and power conversion efficiency (PCE) after
exposure in ambient conditions. Inverted OPVs comprised of
ITO/ZnO/poly(3-hexylthiophene-2,5-diyl):phenyl-C61-butyric acid methyl ester
(P3HT:PCBM)/Ag demonstrate over 3.5% power conversion efficiency only if the
devices are exposed in air for over 4 days. As concluded through a series of
measurements, the oxygen presence is essential to obtain fully operational
solar cell devices without HTL. Moreover, accelerated stability tests under
damp heat conditions (RH=85% and T=65oC) performed to non-encapsulated OPVs
demonstrate that HTL-free inverted OPVs exhibit comparable stability to the
reference inverted OPVs. Importantly, it is shown that bare Ag top electrodes
can be efficiently used in inverted OPVs using various high performance
polymer:fullerene bulk heterojunction material systems demonstrating 6.5% power
conversion efficiencies
Grief and Avoidant Death Attitudes Combine to Predict the Fading Affect Bias
The fading affect bias (FAB) occurs when unpleasant affect fades faster than pleasant affect. To detect mechanisms that influence the FAB in the context of death, we measured neuroticism, depression, anxiety, negative religious coping, death attitudes, and complicated grief as potential predictors of FAB for unpleasant/death and pleasant events at 2 points in time. The FAB was robust across older and newer events, which supported the mobilization-minimization hypothesis. Unexpectedly, complicated grief positively predicted FAB, and death avoidant attitudes moderated this relation, such that the Initial Event Affect by Grief interaction was only significant at the highest 3 quintiles of death avoidant attitudes. These results were likely due to moderate grief ratings, which were, along with avoidant death attitudes, related to healthy outcomes in past research. These results implicate complicated grief and death avoidant attitudes as resiliency mechanisms that are mobilized during bereavement to minimize its unpleasant effects
