Healthy hemlock trees, Tsuga canadensis (L.) Carrière, and hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), populations should favor retention and population growth of adelgid predators such as Laricobius nigrinus Fender (Coleoptera: Derodontidae) and Sasajiscymnus tsugae (Sasaji & McClure) (Coleoptera: Coccinellidae). Eastern hemlock trees between 15 and 38 cm diameter at ...

Understanding how fertilization affects host resistance to hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), is important because fertilizers are often used to grow resistant selections to a suitable size for testing. We evaluated four hemlock species (Tsuga) under three different fertilizer regimes to assess whether fertility affected resistance to the adelgid and to determ...

Fender and Julesz [J. Opt. Soc. Am. 57, 819 (1967)] moved pairs of retinally stabilized images across the temporalward visual fields and found significant differences between the disparities that elicited fusion and the disparities at which fusion was lost. They recognized this phenomenon as an example of hysteresis. In the work reported in this paper, binocular retinally stabilized images of v...

Piles used in bridges, structures and marine environments are typically produced using concrete, steel, and timber. High repair and replacement costs of these piles have led North American highway agencies and port authorities to investigate the feasibility of using durable materials such as fiber-reinforced polymers (FRP) in pile applications. This paper presents a new generation of composite ...

Tire sensors embedded in a vehicle tire are stand-alone autonomous devices. A sensor reserve power strategy is crucial due to energy sources limitations for long operational periods. This paper presents an innovative powering the intelligent-tire system. The offers green concept, maintenance-free, and low-cost method order extend lifetime operating proposed adopts wireless transfer (WPT) techno...

Abstract: This paper presents the methodologies developed in order to provide quality control and analyze the data acquired in hydrodynamic seakeeping experiments of physical models in waves. In such experiments, the data files consist of wave elevations and directions, loads, motions, velocities and accelerations for one or multiple bodies. Additionally, mooring, slamming, sea-fastening, fende...

The aim of this paper is to give a short description of the nature of books and journals, their respective editors, and the difficult process and proprieties involved in publishing papers. It describes some of the main features of the publication process, so that readers may be in a better position to make judgements about published work and writers may be, to some extent at least, prepared to ...
