BACKGROUND The expansion of store-and-forward teledermatology into underserved regions of the world has long been hampered by the requirement for computers with Internet connectivity. To our knowledge, this study is one of the first to demonstrate the feasibility of teledermatology using newer-generation mobile telephones with specialized software and(More)
Rwanda still faces major hurdles in its effort to achieve universal access to health care for all. Even though there is an improvement in overall population health status and community-based funding of insurance coverage, a large percentage of women still deliver their babies at home assisted by unskilled birth attendants or unassisted. This paper examines(More)
Let f := p/q ∈ K(x) be a rational function in one variable. By Lüroth's theorem, the collection of intermediate fields K(f) L K(x) is in bijection with inequivalent proper decompositions f = g • h, with g, h ∈ K(x) of degrees ≥ 2. In (Alonso, Gutierrez & Recio 1995) an algorithm is presented to calculate such a function decomposition. In this paper we(More)
To address whether there are associations between the peptide composition of human parotid saliva and dental decay (caries) experience, we have characterized the peptides from parotid ductal saliva collected from nine adults who have remained free from dental caries (mean age = 59.2; Decayed Missing Filled Surfaces index [DMFS] = 0) and nine individuals who(More)
BACKGROUND It has been suggested that autistic patients have elevated blood androgens, and although signs of precocious puberty have been reported in autistic patients, such a relation has not yet been clarified. OBJECTIVES To assess serum androgen levels in a group of Egyptian male autistic children and adolescents and their relation to disease severity.(More)
Complexes of Co(II), Ni(II) and Cu(II) with substituted phenylazo-6-aminouracils containing (-H, p-OH, p-CH(3), p-OCH(3) p-COOH) have been synthesized and characterized by elemental analysis, magnetic measurements and spectral measurements (IR, UV-Vis, ESR). Infrared spectra assigned the fundamental bands of the major groups, O-H, N-H, C-H, C=O, C=N, N=N,(More)
Let A be a finite union of disjoint sets of consecutive integers and let n be a positive integer. We give a formula for the number of relatively prime subsets (resp., 1 relatively prime subsets of cardinality k) of A, which generalizes results of Nathanson, El Bachraoui and others. We give as well similar formulas for the number of subsets with gcd coprime(More)
