1. DESIGN AND EXPERIMENT OF SELF-PROPELLED SYSTEM FOR PADDY FIELD WEEDER BASED ON THE INTERACTION MECHANISM OF WHEEL-SOIL
ABSTRACT Aiming at the low mechanization of paddy field weeding and lack of dedicated agricultural machinery for paddy field weeding in China, a self-propelled system of paddy field weeding machine was designed. The overall structure and working principle of self-propelled system were illustrated and analyzed. The interaction mechanism of wheel-soil during w

2. Flexible pavement overlay design of UFJF ring road based on the new Brazilian mechanistic-empirical pavement design method
Abstract The procedures for design and reinforcement projects regarding flexible pavements available in Brazil are mostly based on empirical models developed from studies carried out in specific localities, and therefore, should only be used in cases where equivalent climatic and traffic conditions are observed. The national highway agencies in partnership w

3. Estimation of mercury released from an abandoned gold mine in Minas Gerais, Brazil
Abstract Mining is very important to the economic, political and social development of the Minas Gerais State in Brazil ever since the time the country became a Portuguese colony in the early 1500s. However, few researches have been conducted to evaluate the environmental impacts associated with the mining activity at this time. There are many abandoned mine

4. Design associativo: análise da topografia no traçado de vias e quadras
Resumo Em projetos de loteamentos, há uma diversidade de requisitos normativos e de usuários envolvidos a serem considerados, entre os quais as relações entre topografia, sistema viário e custo. O uso do design associativo como instrumento para visualização dessas relações pode auxiliar na tomada de decisões e resoluções de problemas de projeto.

5. Two innovative Brazilian programs relating to road safety prevention. A case study
ABSTRACT BACKGROUND: The World Health Organization (WHO) 2017 Global Conference in Montevideo, Uruguay, was dedicated to promoting successful cases and best practices in fighting and preventing noncommunicable disease (NCDs). The global effort undertaken by WHO aims to reduce road traffic deaths in order to meet goal number 3.4 of the sustainable developme

6. The impact of haulroad geometric parameters on open pit mine strip ratio
Abstract The aim of the study was to analyze the impact on the strip ratio (SR) through varying haul road geometric parameters in two types of deposits, namely one with a steeper dip and a second one with a more equidimensional horizontal behavior. The SRs and the overall slope angle were compared with a base scenario, where the results show an increase in t

7. Development of a Heavy Containment Level Bridge Rail for Istanbul
Abstract The international highways within the city limits of Istanbul are used to transit more than 15 million trucks and other heavy good vehicles per year. According to the statistics, the number of single truck run of the road accidents is in the rise. Recent accidents on bridges showed that currently used bridge rails specified by Istanbul Metropolitan

8. River of Blood: George Martin’s Fevre Dream and the Road to Dark Design
Abstract With his publication of Fevre Dream in 1982, George R. R. Martin tried his hand at the “sympathetic vampire” tale, one popularized just a few years previously by Anne Rice. A tale of vampires haunting the American South during the lead up to the Civil War, Fevre Dream focused upon moral ambiguity, the brutality of power, and other narrative aspe

9. Determination of the Main Influencing Factors on Road Fatalities Using an Integrated Neuro-Fuzzy Algorithm
Abstract This paper proposed an integrated algorithm of neuro-fuzzy techniques to examine the complex impact of socio-technical influencing factors on road fatalities. The proposed algorithm could handle complexity, non-linearity and fuzziness in the modeling environment due to its mechanism. The Neuro-fuzzy algorithm for determination of the potential influ

10. Factores asociados al uso del casco de protección en dos ciudades de Colombia
Abstract The aim of this study was to identify the prevalence and some characteristics associated with the use of motorcycle helmets in two Colombian cities. The researcher used quantitative and qualitative techniques. The prevalence of the use of a motorcycle helmet among motorcyclists was greater in Ibague (98.1%) than in Valledupar (82.4%); among passenge

11. Concrete road barriers subjected to impact loads: An overview
Abstract Concrete barriers prevent vehicles from entering the opposite lane and going off the road. An important factor in the design of concrete barriers is impact load, which a vehicle exerts upon collision with a concrete barrier. This study suggests that a height of 813 mm, a base width of 600 mm, and a top width of 240 mm are optimum dimensions for a co

12. Predictive modeling of entry flow at rotary intersections in Akure, a developing city and capital of Ondo state, Nigeria
Abstract Predictive models for entry flow at rotary intersections in Akure - a developing city in Nigeria- have been developed. Data were collected at the intersections critical to traffic flow in the study area using a cine camera placed at a vantage point from the road sections during peak and off-peak periods in week days. Entry flow (qe) was modelled as
