Background/Aims: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the go-to method for obtaining samplesfrom gastrointestinal tract and pancreatic lesions. When the transduodenal approach is utilized, the use of a more flexible needle,such as a nitinol 19-gauge (G) needle, has been recommended. The aim of this study was to evaluate the feasibility and accuracy of19-G flexible aspiration needles in obtaining samples from solid lesions through a transduodenal approach. Methods: This was a retrospective analysis of prospectively collected data from eight Italian endoscopy centers. Consecutive patientswith solid lesions who underwent transduodenal EUS-FNA with a 19-G flexible needle were included. Results: A total of 201 patients were enrolled. According to histology, EUS, radiology and 12 months of follow-up, 151 patientshad malignant lesions and 50 patients had benign lesions. EUS-FNA was feasible in all cases. An adequate histologic sample wasobtained in all except eight cases (96.1%). The sensitivity of EUS-FNA was 92.1% (95% confidence interval [CI], 86.8%–95.7%), andthe specificity was 100% (95% CI, 90.5%–100%). The positive predictive value was 100% (95% CI, 93.4%–100%), and the negativepredictive value was 74% (95% CI, 62.8%–82.7%). The diagnostic accuracy was 93.5% (95% CI, 89.2%–96.5%). Conclusions: The transduodenal approach for obtaining samples from solid lesions using a 19-G flexible needle seems feasible andaccurate.

This paper discusses the framework conditions to promote the socially inclusive and environmentally sound uptake of renewable energy with a special focus on wind power in Germany and on the policy framework of the European Union (EU). The analysis of these aspects relates to the achievement of one of the Sustainable Development Goals, namely SDG 7 (affordable and clean energy). Wind power plays an important role for mastering the energy transition, but in many countries of the EU, wind energy has become a subject of contested debates. Besides geographic, market, policy, and other factors which affect the implementation of wind energy projects, low levels of market deployment can also be attributed to a diminishing social acceptance and growing local opposition. This is mostly due to the visual impact, noise annoyance, public perception of health risks, local environmental disruption harming local fauna and flora, potentially negative impact on recreation and tourism, or land and real property values as well as to perceived procedural or distributional injustice including affordability of electricity prices, and insufficient public participation. The paper provides insights from an ongoing research project supported by the European Commission under the research programme Horizon 2020. The WinWind Project identifies similarities and differences between regions in five EU countries and in Norway highlighting barriers and drivers for the uptake of wind energy. The paper analyses the European and the German policy frameworks, social acceptance barriers and drivers in two regions of East Germany, and describes promising approaches that drive social acceptance and enhance the environmentally sound uptake of wind energy projects.

Agricultural Employment, Wages and Poverty in Developing Countries
Katsushi IMAI,Raghav GAIHA,Constanza DI NUCCI 연세대학교 빈곤문제국제개발연구원 2014 Journal of Poverty Alleviation and International D Vol.5 No.2
Drawing upon panel data estimations, we have analyzed relationships between agricultural productivity, employment, technology, openness of the economy, inequality in land distribution and poverty. First, we have identified a number of important factors affecting agricultural productivity, such as agricultural R&D expenditure, irrigation, fertilizer use, agricultural tractor/machinery use, reduction in inequality of land distribution, and reduction in gender inequality. Second, while agricultural wage rates are negatively associated with agricultural productivity and food price in terms of levels, rising agricultural wage rates are positively correlated with growth in agricultural land and/or labor productivity as well as with growth in food prices, particularly after 2000. Contrary to the International Labor Organization’s 2012 claim of a widened gap between wage and labor productivity, this finding suggests a narrowing gap once the conditional relationship between the two is taken into account. Third, agricultural employment per hectare tends to increase agricultural productivity after taking account of the endogeneity of the former, while growth in agricultural employment per hectare tends to increase growth in non-agricultural employment over time with adjustment for the endogeneity of the former. Fourth, both agricultural growth and non-agricultural growth tend to lead to a reduction in overall inequality. Finally, increases in agricultural productivity (which is treated as endogenous) will reduce poverty significantly through contributing to overall economic growth. Overall, policies to increase agricultural productivity and agricultural employment are likely to increase non-agricultural growth, overall growth and reduce poverty. The presence of institutional frameworks to promote greater equality between men and women is likely to be one of the key factors, consistent with the important role of women in promoting agricultural productivity in developing countries.

Self-cleaning measurements on tiles manufactured with micro-sized photoactive TiO<sub>2</sub>
Bianchi, C.L.,Gatto, S.,Nucci, S.,Cerrato, G.,Capucci, V. Techno-Press 2013 Advances in materials research Vol.2 No.1
Heterogeneous photocatalysis is a rapidly developing field in environmental engineering. It has a great potential to cope with the increasing pollution in the air. The addition of a photocatalyst to ordinary building materials such as tiles, concrete, paints, creates environmental friendly materials by which air pollution or pollution of the surface itself can be controlled and diminished. This work reports the results of the laboratory research, especially carried out towards air purifying action and self-cleaning measurements. In particular the research was focused on the study of the photocatalytic behavior of industrially prepared tiles produced starting from commercial micro-sized $TiO_2$. Air purification action has been investigated through NOx degradation tests. On the contrary, the degradation of pollution at the surface, also called as self-cleaning action, is verified by the degradation of two different organic dyes: Rhodamine B (red color) and Metanil yellow (yellow).
