Urban pollution and ecosystem services

Urban pollutants can degrade and inhibit ecological functions and processes. Those natural processes provide vital benefits and services to humans. The ‘services’ range from food and water provision, to aesthetics, cultural benefits, health and recreation opportunities, and also climate regulation (including water and air quality regulation and flood regulation). These services are referred to collectively as ecosystem services (ES). To understand the impacts of urban pollution, and the opportunities for mitigating its effects, it is important to explore the relationship between pollution and ES. This can lead to better decision-making for urban infrastructure and spaces and can provide increased opportunities for gaining multiple ES from urban environments

Electroweak corrections to top-quark pair production in quark--antiquark annihilation

Top-quark physics plays an important role at hadron colliders such as the Tevatron at Fermilab or the LHC at CERN. Given the planned precision at these colliders, precise theoretical predictions are required. In this paper we present the complete electroweak corrections to QCD-induced top-quark pair production in quark--antiquark annihilation. In particular we provide compact analytic expressions for the differential partonic cross section, which will be useful for further theoretical investigations

Teachers' Perspective On the Textbook " When English Rings the Bell"

The implementation of curriculum in Indonesia nowadays slightly confuses the teachers. In as much as, there are two curricula that are applied in Indonesia; KTSP and 2013 curriculum. As a result, the textbooks that are used in teaching learning process are also two textbooks. The schools that apply 2013 curriculum use textbook When English Rings the Bell for teaching learning process. Based on researcher’s observation and initial interview when teaching practice in SMPN 2 Banda Aceh, she found that the teachers face a lot of challenges in using this textbook as it is the new book that they have just used. As a result, the researcher wrote the thesis entitled Teachers’ Perspective on the Textbook “When English Rings the Bell”. This research was intended to find out teachers’ perspective on the textbook When English Rings the Bell and teachers’ demand on the textbook based on students’ need. The subjects of this research are two English teachers of SMPN 2 Banda Aceh who were teaching in the first grade. To obtain the data, the researcher used observation and interview technique. The data were analyzed descriptively. In general based on data gathered, the teachers at SMPN 2 Banda Aceh have similar perspective toward the textbook. According to them, When English Rings the Bell is a good textbook for teachers and students. There are some best parts of this textbook; interesting, accessible, based on students’ cultural background, and based on the aim of the curriculum. Besides the strengths, the book also has the weaknesses; it doesn’t cover listening and reading skill and it has few materials and explanation. Therefore, teachers at SMPN 2 Banda Aceh suggested that the material provided in the textbook must be more complete. Hence the students can use it easily to study independently. Furthermore, Materials for reading and listening must be added so that the students can get all four skills in balance

Second research for the local mobility based on the idea of local production and local consumption in Nagaoka city

application/pdfWe are conducting research on local production mobility since 2015. In 2016, prototype No.1 was completed, and No.2 was produced reflecting the improvement points found by testing. No.2 incorporates specifications that satisfy the regulations on the premise of public road driving. We changed the frame shape to make it easier to use for the user group including the elderly according to the questionnaire survey, and raised the motor output, so that it was aimed for ease of use. Based on this, it started moving towards acquiring the premise of public road driving.departmental bulletin pape
