Trujillo, Peru

The National University of Trujillo is a major public university located in Trujillo, Peru, capital of the department of La Libertad. The university was founded by Simón Bolívar and José Faustino Sánchez Carrión, who met in Huamachuco; they signed the decree of foundation on May 10, 1824, before Peru's independence from Spain. National University of Trujillo, was the first republican university founded in Peru.UNT has approximately 19,000 students in 12 academic faculties, making it one of the largest universities in the country. The current headmaster is Dr. Victor Carlos Sabana Gamarra.The UNT is ranked as one of the best universities in Peru. Wikipedia.

We studied the production and signatures of doubly charged Higgs bosons in the process γe-→H--E+, where E+ is a heavy lepton, at the e-e+ International Linear Collider (ILC) and CERN Linear Collider (CLIC). The intermediate photons are given by the Weizsäcker-Williams and laser-backscattering distributions. We found that significant signatures are obtained by bremsstrahlung and backward Compton scattering of laser. A clear signal can be obtained for doubly charged Higgs bosons, doubly charged gauge bosons and heavy leptons. © 2012 Springer-Verlag Berlin Heidelberg and Società Italiana di Fisica. Source

This work explores the effects of European contact on Andean foodways in the Lambayeque Valley Complex, north coast Peru. We test the hypothesis that Spanish colonization negatively impacted indigenous diet. Diachronic relationships of oral health were examined from the dentitions of 203 late-pre-Hispanic and 175 colonial-period Mochica individuals from Mórrope, Lambayeque, to include observations of dental caries, antemortem tooth loss, alveolar inflammation, dental calculus, periodontitis, and dental wear. G-tests and odds ratio analyses across six age classes indicate a range of statistically significant postcontact increases in dental caries, antemortem tooth loss, and dental calculus prevalence. These findings are associated with ethnohistoric contexts that point to colonial-era economic reorganization which restricted access to multiple traditional food sources. We infer that oral health changes reflect creative Mochica cultural adjustments to dietary shortfalls through the consumption of a greater proportion of dietary carbohydrates. Simultaneously, independent skeletal indicators of biological stress suggest that these adjustments bore a cost in increased nutritional stress. Oral health appears to have been systematically worse among colonial women. We rule out an underlying biological cause (female fertility variation) and suggest that the establishment of European gender ideologies and divisions of labor possibly exposed colonial Mochica women to a more cariogenic diet. Overall, dietary change in Mórrope appears shaped by local responses to a convergence of colonial Spanish economic agendas, landscape transformation, and social changes during the postcontact transition in northern Peru. These findings also further the understandings of dietary and biocultural histories of the Western Hemisphere. Am J Phys Anthropol 141:594-609, 2010. © 2009 Wiley-Liss, Inc. Source

In this paper, we are interested in the nonlinear Schrödinger equation with non-local regional diffusion 1 (-Δ)ραu+u=f(x,u)inRn,u∈Hα(Rn), where 0 < α < 1 and (-Δ)ρα is a variational version of the regional Laplacian, whose range of scope is a ball with radius ρ(x) > 0. The novelty of this paper is that, assuming f is of subquadratic growth as |u|→+∞, we show that possesses infinitely many solutions via the genus properties in critical point theory. Furthermore, if f(x,u) = γa(x)|u|γ - 1, where γ∈(1,2),a∈L22-γ(Rn,R+) is a nonincreasing radially symmetric function, then the solution of is radially symmetric. © 2015 John Wiley & Sons, Ltd. Source

This paper presents a first approximation obtained from the use of space syntax in residential households in the ancient Moche city (s. VII-IX AD). Studies in the site of Temples of the Sun and Moon have elucidated that during the last centuries of occupation, the theocratic system collapsed and a change began towards a new political and ideological system by the new ruling elites. The analyses have allowed us to understand the logic of built space in three households' complex and show a high understanding of hierarchy and spatial distribution by its former inhabitants. Obviously, the use of Archaeology of architecture in societies like the Moche requires more studies, because these households have very complex internal divisions, where the spatial unit does not always work independently, but in many cases are linked with other constituting a complex functional space. © 2015 CSIC.

Candida albicans population studies showed that this species could be divided into sub-groups of closely related strains, designated by clades. Since the emergence of microsatellite analysis as a PCR based method, this technique has been successfully used as a tool to differentiate C. albicans isolates but has never been tested regarding clustering of the five major clades. In this study we tested microsatellite length polymorphism (MLP) ability to group 29 C. albicans strains previously defined as belonging to clades I, II, III, E and SA, nine atypical strains from Angola and Madagascar, and 78 Portuguese clinical isolates. MLP typing of the total 116 strains analyzed yielded 87 different multilocus allelic combinations which resulted in a high discriminatory power index, of 0.987, with only two markers, CA1 and CEF3. Cluster analysis of the 29 previously defined strains grouped them according to their clade designation with a matrix cophenetic correlation of r=0.963 after a normalized Mantel statistic. Clustering analysis of the 116 strains maintained the same groupings, clearly defining the five major C. albicans clades. The cophenetic value obtained was of r=0.839, and the one-tail probability of the normalized Mantel statistic out of 1000 random permutations was P=0.0020. The proportion of Portuguese isolates in the groups I, II, III and SA was of 2.7%, 15.4%, 3.8% and 0%, respectively. None of the isolates co-clustered with the atypical strains. These results confirm MLP typing as a good method both to type and differentiate C. albicans isolates and to group isolates, identifying the major C. albicans clades, similarly to Ca3 fingerprinting and multilocus sequence typing (MLST). © 2010 Elsevier B.V.
