Referring to an old proverb – " a picture says more than a thousand words " –, this article should be seen as a comment to the following reconstruction drawings of PPNB architecture from Ba'ja, Basta, and Shkârat Msaied. The PPNB architecture of southern Jordan, especially in the Greater Petra Area, is said to be " well known " from sites like Basta, 'Ain Jammam, es-Sifiya, al-Basît, Ba'ja and ...

In 2017, Baltimore City was awarded $75 million earmarked for the targeted demolition of a portion its 16,000 vacant and abandoned buildings. Selecting an optimal set targets is difficult given that cost per not independent overall pattern; like many older cities, Baltimore’s housing includes large number attached row houses, which require construction retaining walls when demolished home abuts...

We develop an adaptive finite element method for island dynamics in epitaxial growth. We study a step-flow model, which consists of an adatom (adsorbed atom) diffusion equation on terraces of different height; thermodynamic boundary conditions on terrace boundaries including anisotropic line tension; and the normal velocity law for the motion of such boundaries determined by a two-sided flux, t...

We consider irreversible second-layer nucleation that occurs when two adatoms on a terrace meet. We solve the problem analytically in one dimension for zero and infinite step-edge barriers, and numerically for any value of the barriers in one and two dimensions. For large barriers, the spatial distribution of nucleation events strongly differs from rho(2), where rho is the stationary adatom den...

This paper is about the introduction of an electric car rental system in the city of Amsterdam. These cars can be used as an alternative to public transport or taxis by travelers or tourists arriving at train stations or park houses who want to reach places in the inner city. After the trip, cars will be parked in one of the park houses distributed over the city close to the traveler’s destinat...

BACKGROUND We recently developed HOUSES, an individual housing-based socioeconomic status (SES) measurement for health disparities research. We assessed whether HOUSES was associated with risk of pertussis and pertussis vaccine up-to-date status in children. METHODS The study utilized a previous population-based case-control study cohort assembled during the 2004-2005 pertussis outbreak. We c...

The effectiveness of three operational strategies for the control of Triatoma dimidiata was compared by a field trial in the Department of Madriz, Nicaragua. One strategy involved full pretrial evaluation, followed by spraying of all houses irrespective of whether or not they had been found to be infested. The second strategy minimised the pretrial evaluation by considering the locality infeste...
