Pest risk analysis for Bactrocera invadens : Guidelines on Pest Risk Analysis

Stripping related moisture damage has been recognized as one of the major pavement distresses since the early 1990s. The main objective of this study is to establish an effective test protocol to quantify moisture susceptibility of asphalt pavements. To this end, selective test methods (Texas Boiling test, Tensile Strength Ratio, Retained Stability, and Hamburg Wheel Test), and procedures based on surface chemistries and molecular-level mechanistic properties have been investigated in this study. Firstly, a comprehensive list of literature related to moisture damage in asphalts was reviewed. Based on the literature review, a detailed project plan and test matrix were developed. Binder samples originated from two different crude sources were collected. The moisture resistance related tests such as static contact angle measurements and Texas Boiling tests were conducted. Besides, asphalt binders’ nanomechanical properties using an Atomic Force Microscopy (AFM) and surface chemistries using a static contact were evaluated in the laboratory. Based on limited test data and analysis, it is concluded that there does not exist any single test method that all agencies are comfortable and equipped to follow in their daily work as each technique has some merits and demerits. However, the Texas Boiling test is found to be the simplest method that requires minimal time and resources. On the other hand, surface chemistry and atomic force microscope-based techniques are becoming popular among researchers and pavement professionals. Findings of this study are expected to help ARDOT in selecting an appropriate moisture resistance test method that is simple, reliable, and easy to implement in their routine work

Learning Takes Flight: Award-Winning Educators Use Aviation to Spark Student Achievement

Eleven teachers from eight different states were chosen as 1991 winners of the General Aviation Manufacturers Association (GAMA) annual Award for Excellence in Aviation Education. The award honors grade school and high school teachers who bring general aviation into the classroom, either as a specific topic of discussion or as a teaching tool. Most of the winning projects included activities spread over an entire semester or school year. From each winning entry, two or three of the most original or vivid ideas were selected for this article. Enough detail was included so that another teacher can take the ideas and develop his or her own teaching activity. Another intent of this article is to show that aviation-related themes work for all ages and kinds of learners. A summary of the award winners follows
