background the treatment of onychomycosis is a challenge and infections are typically more severe and difficult to treat in toenails than in fingernails. objectives the current study aimed to investigate the fungicidal effect of ultraviolet radiation on the growth of dermatophytes isolated from nails. patients and methods samples from patients with clinical manifestations of onychomycosis were ...

The possibility of detecting proto-galaxies in the UV band is pointed out, assuming galaxy formation occured at z ∼ 5−6. It is shown that the diffuse gas in collapsing galaxy sized objects with temperatures ∼ 10 K, and with a modest amount of metallicity, should copiously produce emission lines from highly ionized Iron atoms. The expected luminosity from models of galaxy formation is compared w...

[1]Zirconametalloarenophanes [Cr(η(5)-C(5)H(4))ZrCp'(2)(η(7)-C(7)H(6))] and [Mn(η(5)-C(5)H(4))ZrCp'(2)(η(6)-C(6)H(5))] (Cp' = C(5)H(4)(t)Bu) have been isolated for the first time. These species represent potential precursors en route to metal-enriched metallopolymers by ROP. The electronic structure was assessed by means of UV-visible spectroscopy and TD-DFT calculations.

A procedure for fabrication of photomasks on photographic films with minimum feature achievable of about 20 μm, which are particularly suitable for the fast prototyping of microfluidic devices, has been improved. We used a commercial photographic enlarger in reverse mode obtaining 10:1 reduction factor with error less than 1%. Masks have been characterized by optical transmission measurement an...

The spatial distribution of Lyα forest absorption systems toward a group of 8, closely spaced QSOs has been analysed and evidence for large scale structure has been found at z = 2.8. Our technique is based on the first and second moments of the transmission probability density function which is capable of identifying and assessing the significance of regions of over-or underdense Lyα absorption...

The manuscript describes a method to obtain spectral aerosol optical thicknesses from measurements with a spectroradiometer in the UV-visible range. The direct solar light is inferred from the difference between total radiation and diffuse radiation. The latter is obtained by the use of a sun blocking disc. An error budget is presented. The results are validated against the measurements with a ...

In the naive form of most resummations we get into conflict with order-by-order renormalization. We present a method that is capable to ensure UV consistency of any resummations satisfying certain conditions. The method is based on the observation that resummation is equivalent with a calculation in an adequate perturbation scheme, followed by a renormalization scheme changing. This framework w...
