This work presents a theoretical/numerical study of the micromechanical behavior of asphalt concrete. Asphalt is a heterogeneous material composed of aggregates, binder cement and air voids. The load carrying behavior of such a material is strongly related to the local load transfer between aggregate particles, and this is taken as the microstructural response. Numerical simulation of this mate...

All actually used SAW sensors have in common that they analyze the transmission characteristics of propagating SAWs. Here, a portable device using the SAW-based impedance sensor type based on one interdigital transducer (IDT) simultaneously as SAW generator and sensor element (1-port approach) is presented. The input port reflection coefficient S11 is measured at the IDT instead of the commonly...

MMT (Methadone maintenance treatment) is an effective way to treat opioid dependence. In Portugal, an MMT program has been available in pharmacies since January 1998, when a formal agreement was signed by the IDT, I.P. (Institute on Drugs and Drug Addiction), the PPS (Portuguese Pharmaceutical Society), and the ANF (National Association of Pharmacies). In January 2004, the INFARMED (National Au...

This dissertation examines the issue of academic preparation of future professional instructional designers in the context of higher academic institutions. It is presented in nontraditional dissertation format as approved by the Department of Curriculum and Instruction, Iowa State University. The dissertation is comprised of three publishable journal articles that would represent Chapters 2, 3 ...

Purpose. In this retrospective case review we analyze the outcomes of patients treated for intradiverticular bladder tumors (IDT). Materials and Methods. A retrospective case review was done between January 2002 and May 2014 in Hotel-Dieu de France hospital. The series included 17 patients diagnosed with IDT, all males with a mean age of 49.8 years. Results. One patient was treated with tumor r...

In human and veterinary medicine IDT remains the “gold-standard” for diagnosing allergic skin disease although SAT is popular because of its convenience. Many laboratories will test a single equine serum sample against a panel of common equine allergens. However, in one study of three commonly used equine SAT’s, all tests had poor sensitivity and poor positive predictive value when compared to ...

Background and Objective: There is some concern among physicians that a positive history of adverse reactions to drugs and/or atopic disease remains a risk factor for developing a hypersensitivity reaction to local anesthetics (LA). In the present study we aimed allergy testing to LA is justified in patients with a positive history of hypersensitivity reactions to drugs additionally by atopy an...

Large-eddy simulations (LES) coupled with a partially-stirred reactor model and finite-rate chemistry are carried out to investigate the effects of n-heptane injection timing on methanol fueled dual-fuel (DF) combustion. Methanol is premixed air in constant volume chamber (T=1000 K, ρ=14.8 kg/m3) form homogeneous mixture (equivalence ratio ϕm 0.3). Liquid fuel provided from high pressure inject...

In this study, we investigate the effect of different split injection strategies on ignition delay time (IDT) and heat release rate (HRR) characteristics in Reactivity Controlled Compression Ignition conditions via large-eddy simulation finite-rate chemistry. A diesel surrogate (n-dodecane) is injected into a domain with premixed methane oxidiser two separate pulses. Three are investigated by f...

In the description of object shapes, humans usually performiconic gestures that coincide with speech (are coverbal). Marked by asimilarity between the gestural sign and the described object, iconic ges-tures may easily depict content difficult to describe using words alone.Though the expressive potential of iconic gestures in human-computercommunication is generally acknowle...
