This thesis describes the development of a knowledge-based system to evaluate forested land for availability of wildlife habitat. NED is an acronym derived from “Northeast Decision Model”. The NED DSS, a collection of software products, was created to help resource managers to build up goals, access current and potential conditions, and create long-term, landscape-level management plans for for...

in extant islamic manuscripts we can find some observation reports of a black dot on the surface of the sun. these reports add that this dot should be the planet venus or mercury, transiting over the sun, showing that both of them are below the sphere of the sun. the research made so far on ibn sina’s report shows that it might relate to a really observed venus transit. quṭb al-dīn al-shīrāzī (...

Informal workers in African market trade have little formal protection against sun exposure. We aimed to examine sun exposure, sun-related symptoms, and sun protection practices in an informal occupational setting. Trained fieldworkers asked 236 workers in the Warwick Junction market about their workplace, skin and eye sensitivity and skin colour, symptoms faced at work during the summer due to...

Objective(s) Studies have described immunomedulatory effects of sun exposure and ultraviolet radiation on infectious and neoplastic diseases. Here the effect of exposure to low potency radiation of sun on the course of leishmaniasis in mice was studied. Materials and Methods Fifteen BALB/c mice were exposed to suberythemogenic doses of sun (mean 180 mJ/cm2/day of UVB) 2 months before and 4 m...

In modern computer systems, long-running jobs are divided into a large number of short tasks and executed in parallel. As the system size and complexity scales up, the task service times become highly random and the job service time is constrained by the slowest straggling tasks. An efficient solution is to replicate a task on multiple servers and wait for one task copy to finish early. However...

A new class of singlet superconductors with a gap function ∆(k, ωn) which is odd in both momentum and Matsubara frequency is considered. Some of the physical properties of this superconductivity are discussed and it is argued that: i) the electron-phonon interaction can produce this kind of pairing, ii) in many cases there is no gap in the quasiparticle spectrum, iii) these superconductors will...
