Sub-nanometre resolution imaging of polymer-fullerene photovoltaic blends using energy-filtered scanning electron microscopy

The resolution capability of the scanning electron microscope has increased immensely in recent years, and is now within the sub-nanometre range, at least for inorganic materials. An equivalent advance has not yet been achieved for imaging the morphologies of nanostructured organic materials, such as organic photovoltaic blends. Here we show that energy-selective secondary electron detection can be used to obtain high-contrast, material-specific images of an organic photovoltaic blend. We also find that we can differentiate mixed phases from pure material phases in our data. The lateral resolution demonstrated is twice that previously reported from secondary electron imaging. Our results suggest that our energy-filtered scanning electron microscopy approach will be able to make major inroads into the understanding of complex, nano-structured organic materials

Kwentong Pambata: Interactive Storybook for Filipino Fables, Legends, Parables and Short Stories

This paper focused on the development and evaluation of a mobile application in which children could interact, be entertained, and especially be educated at the same time. It was mainly designed for children, parents/guardians, and teachers as well. The interactive storybook which was created was different from those available in the market.  Kwentong Pambata is a children’s storybook application designed for Android devices that features Filipino legends, fables, parables and short stories designed for Filipino children and children all over the world. It portrays Filipino values, traditions and character which contains moral lesson at the end of each story that would educate children’s view in life, their characters, moral uprightness, and values. It is a storybook which contains fun pictures, texts, and sounds that kids will truly enjoy. The goal of the study is to develop an Android application that children could interact, learn, read, be entertained, improve and develop children’s imagination and comprehension skills at an early age, and to promote Filipino stories and moral values. Kwentong Pambata application was developed using ActionScript 3.0. and Adobe Flash CS5.5. The application has 3 different language translations such as Filipino, English, and Mandarin. The proponents used ADDIE model for the development of the application. After the development, the application was evaluated. The total number of 40 respondents which were selected through probability sampling is used for the evaluation process. The application was evaluated according to its Usability, Reliability, Efficiency and Graphical User Interface (GUI).  The evaluation questionnaire showed that the application was rated as very satisfactory with the help of the respondents and was improved throughout its revisions

Stimulative Work Valuation Among Real Estate Practitioners in Asia

Real estate or property production has been recognized as one of Asia's key industries. Based on this significance, the authors assessed the work centrality and working values of real estate practitioners in established Asian countries. Based on the findings, in terms of work centrality, Japan was rated high on work centrality as very important in six life aspects among the five countries, followed by Indonesia, the Philippines, Malaysia, and Myanmar. Findings on work values were all significant among the five countries, headed by Japan, Indonesia, Myanmar, Malaysia, and the Philippines. There is a substantial difference in the perception of work centrality among respondents in five countries, as revealed by Indonesia and Myanmar and Myanmar and Japan. Some countries differ in work values as manifested by Malaysia and Japan, highly significant, like Myanmar and Japan, and the Philippines. Enablers for success in the real estate profession include enterprising and conventional interests and various work values listed by experts in the field. Based on the study's findings, it can be seen that work centrality and work values among the five Asian countries differ from each other. Capability Building Index is now recommended for adoption by the real estate practitioners

Follow-up of phase I trial of adalimumab and rosiglitazone in FSGS: III. Report of the FONT study group

Abstract Background Patients with resistant primary focal segmental glomerulosclerosis (FSGS) are at high risk of progression to chronic kidney disease stage V. Antifibrotic agents may slow or halt this process. We present outcomes of follow-up after a Phase I trial of adalimumab and rosiglitazone, antifibrotic drugs tested in the Novel Therapies in Resistant FSGS (FONT) study. Methods 21 patients -- 12 males and 9 females, age 16.0 ± 7.5 yr, and estimated GFR (GFRe) 121 ± 56 mL/min/1.73 m2 -- received adalimumab (n = 10), 24 mg/m2 every 14 days or rosiglitazone (n = 11), 3 mg/m2 per day for 16 weeks. The change in GFRe per month prior to entry and after completion of the Phase I trial was compared. Results 19 patients completed the 16-week FONT treatment phase. The observation period pre-FONT was 18.3 ± 10.2 months and 16.1 ± 5.7 months after the study. A similar percentage of patients, 71% and 56%, in the rosiglitazone and adalimumab cohorts, respectively, had stabilization in GFRe, defined as a reduced negative slope of the line plotting GFRe versus time without requiring renal replacement therapy after completion of the FONT treatment period (P = 0.63). Conclusion Nearly 50% of patients with resistant FSGS who receive novel antifibrotic agents may have a legacy effect with delayed deterioration in kidney function after completion of therapy. Based on this proof-of-concept preliminary study, we recommend long-term follow-up of patients enrolled in clinical trials to ascertain a more comprehensive assessment of the efficacy of experimental treatments

Theories of Willpower Affect Sustained Learning

Building cognitive abilities often requires sustained engagement with effortful tasks. We demonstrate that beliefs about willpower–whether willpower is viewed as a limited or non-limited resource–impact sustained learning on a strenuous mental task. As predicted, beliefs about willpower did not affect accuracy or improvement during the initial phases of learning; however, participants who were led to view willpower as non-limited showed greater sustained learning over the full duration of the task. These findings highlight the interactive nature of motivational and cognitive processes: motivational factors can substantially affect people’s ability to recruit their cognitive resources to sustain learning over time

Sodium Chloride Inhibits the Growth and Infective Capacity of the Amphibian Chytrid Fungus and Increases Host Survival Rates

The amphibian chytrid fungus Batrachochytrium dendrobatidis is a recently emerged pathogen that causes the infectious disease chytridiomycosis and has been implicated as a contributing factor in the global amphibian decline. Since its discovery, research has been focused on developing various methods of mitigating the impact of chytridiomycosis on amphibian hosts but little attention has been given to the role of antifungal agents that could be added to the host's environment. Sodium chloride is a known antifungal agent used routinely in the aquaculture industry and this study investigates its potential for use as a disease management tool in amphibian conservation. The effect of 0–5 ppt NaCl on the growth, motility and survival of the chytrid fungus when grown in culture media and its effect on the growth, infection load and survivorship of infected Peron's tree frogs (Litoria peronii) in captivity, was investigated. The results reveal that these concentrations do not negatively affect the survival of the host or the pathogen. However, concentrations greater than 3 ppt significantly reduced the growth and motility of the chytrid fungus compared to 0 ppt. Concentrations of 1–4 ppt NaCl were also associated with significantly lower host infection loads while infected hosts exposed to 3 and 4 ppt NaCl were found to have significantly higher survival rates. These results support the potential for NaCl to be used as an environmentally distributed antifungal agent for the prevention of chytridiomycosis in susceptible amphibian hosts. However, further research is required to identify any negative effects of salt exposure on both target and non-target organisms prior to implementation

Reproductive health and quality of life of young Burmese refugees in Thailand

BACKGROUND: Of the 140,000 Burmese* refugees living in camps in Thailand, 30% are youths aged 15-24. Health services in these camps do not specifically target young people and their problems and needs are poorly understood. This study aimed to assess their reproductive health issues and quality of life, and identifies appropriate service needs. METHODS: We used a stratified two-stage random sample questionnaire survey of 397 young people 15-24 years from 5,183 households, and 19 semi-structured qualitative interviews to assess and explore health and quality of life issues. RESULTS: The young people in the camps had very limited knowledge of reproductive health issues; only about one in five correctly answered at least one question on reproductive health. They were clear that they wanted more reproductive health education and services, to be provided by health workers rather than parents or teachers who were not able to give them the information they needed. Marital status was associated with sexual health knowledge; having relevant knowledge of reproductive health was up to six times higher in married compared to unmarried youth, after adjusting for socio-economic and demographic factors. Although condom use was considered important, in practice a large proportion of respondents felt too embarrassed to use them. There was a contradiction between moral views and actual behaviour; more than half believed they should remain virgins until marriage, while over half of the youth experienced sex before marriage. Two thirds of women were married before the age of 18, but two third felt they did not marry at the right age. Forced sex was considered acceptable by one in three youth. The youth considered their quality of life to be poor and limited due to confinement in the camps, the limited work opportunities, the aid dependency, the unclear future and the boredom and unhappiness they face. CONCLUSIONS: The long conflict in Myanmar and the resultant long stay in refugee camps over decades affect the wellbeing of these young people. Lack of sexual health education and relevant services, and their concerns for their future are particular problems, which need to be addressed. Issues of education, vocational training and job possibilities also need to be considered.*Burmese is used for all ethnic groups
