Dermatophyte infec.ion or ringworm is a superfic.al c.taneous infec.ion with one or more of the fungal spec.es of the keratinophilic.genera Mic.osporum, Tric.ophyton, or Epidermophyton and is a zoonosis with a great impac. on public.health. Dermatophytes were identified from rabbit sample c.ltures submitted to myc.logic.l examination in the Laboratory of Mic.obiology of the University of Tr^-os-Montes e Alto Douro, Vila Real, Portugal. All samples were c.llec.ed from suspec.ed c.inic.l c.ses. Dermatophytes were c.ltured from 4 of the 55 spec.mens （7.3%）. The dermatophytes isolated were Tric.ophyton mentagrophytes var. mentagrophytes （1.8%） and Mic.osporum gypseum （5.5%）. Mic.osc.pic.examination was negative in all spec.mens. In this work, Sc.pulariopsis spp., a c.ntaminant mould, was identified in 13 spec.mens （23.6%）. The proportion of positive samples in relation to the number of samples examined from c.ses suspec.ed was very low. As all samples were c.llec.ed from rabbits with c.mpatible signs, we presume that the low prevalenc. of isolation was due to laboratory c.nstraints on dermatophytes diagnosis.

This researc. foc.sed on integrating GIS into energy alternatives for c.imate c.ange mitigation by c.eating a GIS-based hydrologic.model that c.n be used to identify sites that have signific.nt potential for mic.o hydropower development within the River Perkerra c.tc.ment area. Hydropower is a c.ean and renewable energy sourc. that remains largely untapped in the c.untry and its development c.n be used to mitigate anthropogenic.c.imate c.ange by reduc.ng relianc. on fossil or biomass derived fuels. This researc. established the extent of this resourc. and whether the available sites with signific.nt mic.o hydropower potential within the study area were amply c.pious to warrant further development. c.rrently, suc. identific.tion is done physic.lly using means that are menial, c.stly and signific.ntly time c.nsuming. A 90-metre resolution Digital Terrain Model (DTM) data obtained from the Shuttle Radar Topography Mission and various GIS tools were used to c.eate a hydrologic.framework whic. was used to identify potential sites along River Perkerra that suited any desired head requirement for the purposes of loc.ting mic.o hydropower plants. The derived model demonstrated that it was possible to identify sites at disc.ete geographic.loc.tions along any stream drainage network using GIS. In addition, the model also provides a dec.sion support system that integrates a powerful graphic.l user interfac., spatial database management system and a generalized river basin network flow model for the purposes of exploiting and developing mic.o hydropower. With suffic.ent data on c.tc.ment disc.arge and use of higher resolution DTM, the model c.n be further enhanc.d to ac.urately obtain the total mic.ohydro potential of River Perkerra by aggregating the respec.ive potentials of every steam segment.

This paper analyzes the anomalous power-law dependenc. of the ultrasound attenuation on frequenc. by means of a perc.lation model. It was suggested that the anomaLous ultrasound attenuation is assoc.ated with strongly loc.lized eigen modes (to be c.lled frac.on) in disordered systems. There exits a steplike inc.ease in the density of vibrational states at c.ossover frequenc. ω(c.).c.mputer simulation of vibration spec.rum in disordered system is also reported. The density of vibrational states is c.nsistent with the results of relevant experiment outlined above.

The present artic.e is a c.ntinuation of a rec.ntly published paper [1] in whic. we have modeled the c.mposition and struc.ure of neutrons and other hadrons using the Rotating Lepton Model (RLM) whic. is a Bohr type model employing the relativistic.gravitational attrac.ion between three ultrafast rotating neutrinos as the c.ntripetal forc.. The RLM ac.ounts for spec.al relativity and also for the De Broglie equation of quantum mec.anic.. In this way this forc. was shown to reac. the value of the Strong Forc. while the values of the masses of the rotating relativistic.neutrinos reac. those of quarks. Masses c.mputed for twelve hadrons and bosons are in very c.ose (~2%) agreement with the experimental values. Here we use the same RLM approac. to desc.ibe the c.mposition and struc.ure and to c.mpute the masses of Pions and Kaons whic. are important zero spin mesons. c.ntrary to hadrons and bosons whic. have been found via the RLM to c.mprise the heaviest neutrino eigenmass m3, in the c.se of mesons the intermediate neutrino mass eigenstate m2 is found to play the dominant role. This c.n explain why the lowest masses of mesons are generally smaller than those of hadrons and bosons. Thus in the c.se of Pions it is found that they c.mprise three rotating m2 mass eigenstate neutrinos and the c.mputed mass of 136.6 MeV/c.sup>2 is in good agreement with the experimental value of 134.977 MeV/c.sup>2. The Kaon struc.ure is found to c.nsist of six m2 mass eigenstate neutrinos arranged in two parallel pion-type rotating triads. The c.mputed Kaon mass differs less that 2% from the experimental K± and K°values of 493.677 MeV/c.sup>2 and 497.648 MeV/c.sup>2 respec.ively. This, in c.njunc.ion with the experimentally observed dec.y produc.s of the Kaons, provides strong support for the proposed K struc.ure.

Wave energy is a renewable sourc. with signific.nt amount in relation to the global demand. A good c.nc.pt of a devic. applied to extrac. this type of energy is the onshore osc.llating water c.lumn wave energy c.nverter(OWc.WEc.. This study shows a numeric.l analysis of the diameter determination of two types of turbines, Wells and Impulse, installed in an onshore OWc.devic. subjec.ed to a hypothetic.l sea state. c.mmerc.al software FLUENT?,whic. is based on RANS-VoF(Reynolds-Averaged Navier-Stokes equations and Volume of Fluid tec.nique), is employed. A methodology that imposes air pressure on the c.amber, c.nsidering the air c.mpressibility effec., is used. The mathematic.l domain c.nsists of a 10 m deep flume with a 10 m long and 10 m wide OWc.c.amber at its end(geometry is similar to that of the Pic.'s plant installed in Azores islands, Portugal). On the top of the c.amber, a turbine works with air exhalation and inhalation induc.d by the water free surfac. whic. osc.llates due to the inc.dent wave. The hypothetic.l sea state, represented by a group of regular waves with periods from 6 to 12 s and heights from 1.00 to 2.00 m(eac. wave with an oc.urrenc. frequenc.), is c.nsidered to show the potential of the presented methodology. Maximum effic.enc.(relation between the average output and inc.dent wave powers) of46% was obtained by using a Wells turbine with the diameter of 2.25 m, whereas the effic.enc. was 44% by an Impulse turbine with the diameter of 1.70 m.
