In arid and semi-arid areas of the world, excessive mineral aerosol carried by air parcels is a common climatic incident with well-known environmental side effects. In this study, the role of sand-dust accumulation was investigated on various aspects of photosynthetic yield of Plantago lanceolata including chlorophyll (Chl) a, b, effective quantum yield of PSII photosystem (ФPSII), maximal quan...

The chapter provides a survey of routing protocols in vehicular ad hoc networks. The routing protocols fall into two major categories of topology-based and position-based routing. The chapter discusses the advantages and disadvantages of these routing protocols, explores the motivation behind their design and trace the evolution of these routing protocols. Finally, it concludes the chapter by p...

In this dissertation, we address the problem of discovery and representation of group activity of humans and objects in a variety of scenarios, commonly encountered in vision applications. The overarching goal is to devise a discriminative representation of human motion in social settings that captures a wide variety of human activities observable in video sequences. Such motion emerges from th...

This paper evaluates the suitability of a newly developed hybrid “Langmuir-Maxwell” and “LangmuirSmoluchowski” slip/jump boundary conditions in the Navier-Stokes-Fourier equations for nano/micro backward-facing step geometry flow which experiences separation and reattachment. Additionally, this paper investigates the effect of different parameters such as step pressure ratio, inflow temperature...

INTRODUCTION Iran has a major land mine injury problem in its border areas. Mine injuries have a high mortality and morbidity, and the injuries generally occur in remote areas. Iran has a well developed system of rural health workers and clinics, covering most border areas. These have mainly had prevention, immunization and curative treatment for medical conditions as their focus. We hypothesiz...

Alvin Toffler, a 20th century philosopher and author of the novel Future Shock once said, “As we move into the 21st century, not only will technology advance, but the rate at which technology advances will increase exponentially.”1 Perhaps those technological advances with greatest relevance to the health and welfare of society involve science and healthcare. Indeed, societal demands for new dr...

New Canadian telemedicine technology being tested in an underwater laboratory off the coast of Key Largo in Florida could be used to deliver emergency diagnostic and surgical care to astronauts in space — and to patients in remote areas on Earth. On Oct. 11, North Bay surgeon Dr. Craig McKinley and 3 astronauts-turned-aquanauts will enter the 3 × 14-metre underwater chamber Aquarius for a 10day...
