Annotated checklist, distribution, and taxonomic bibliography of the mosquitoes (Insecta: Diptera: Culicidae) of Argentina

A decade and a half have passed since the last publication of the mosquito distribution list in Argentina. During this time several new records have been added, and taxonomic modifications have occurred at the genus and subgenus level. Therefore, considering these changes, I decided to create an updated list of the 242 species present in Argentina, along with their distributions by province. Two first records for Argentina (Culex lopesi and Cx. vaxus), two old records unregistered by authors (Cx. albinensis and Wyeomyia fuscipes), 13 new provincial records for 11 species (Cx. apicinus, Cx. bidens, Cx. eduardoi, Cx. lahillei, Cx. pipiens, Cx. tatoi, Cx. usquatus, Cx. imitator, Cx. oedipus, Sabethes chloropterus, and Wy. oblita), and the extension of distribution of other species are presented. The list of literature references for the documents concerning mosquitos is included.Fil: Rossi, Gustavo Carlos. Consejo Nacional de Investigaciones Científicas y Técnicas.

Redescription of larva, pupa and adult of <i>Anopheles (Anopheles) annulipalpis</i> (Diptera: Culicidae) and the removal of the specie of the Cycloleppteron series

The redescription of male, female, pupa and larva of Anopheles (Anopheles) annulipalpis Lynch Arribálzaga, 1878 is presented. The species is included in the Cycloleppteron Series of Anopheles, although several authors consider that this is artificial. The redescription of Anopheles annulipalpis demonstrate that pupae have laticorn trumpet. By this fact is compared with An. grabhamii Theobald, 1901 and similar species of the Arribalzagia Series and Myzorhynchus Series. The laticorn type of trumpet joined the other differences and similarities found are sufficient to remove An. annulipalpis of Cycloleppteron Series and included as an unplaced member of the Angusticorn Section.Centro de Estudios Parasitológicos y de Vectore

Detecting Conflicts and Inconsistencies in Web Application Requirements

Web applications evolve fast. One of the main reasons for this evolution is that new requirements emerge and change constantly. These new requirements are posed either by customers or they are the consequence of users’ feedback about the application. One of the main problems when dealing with new requirements is their consistency in relationship with the current version of the application. In this paper we present an effective approach for detecting and solving inconsistencies and conflicts in web software requirements. We first characterize the kind of inconsistencies arising in web applications requirements and then show how to isolate them using a modeldriven approach. With a set of examples we illustrate our approach

Development of a nano-Al/CuO based energetic material on silicon substrate

Nanoenergetic materials nEMs have improved performances compared to their bulk counterpart or microcounterpart. The authors propose an approach to synthesize an Al/CuO based nEM that has several advantages over previous investigations such as enhanced contact, reduced impurities and Al oxidation, tailored dimensions, and easier integration into microsystem. CuO nanowires are synthesized by thermally annealing Cu film deposited onto silicon. Nano-Al is integrated with the nanowires to realize an Al/CuO based nEM. The synthesized nEM is characterized by scanning electron microscopy, high resolution transmission electron microscopy, x-ray diffraction, differential thermal analysis, and differential scanning calorimetry

Antocianinas e gelo seco para visualizar equilíbrios ácido/base numa abordagem contextualizada

Proposem un experiment versàtil i accessible que utilitza gel sec i extractes d'antocianines de fruites per demostrar i discutir conceptes com acidesa, basicitat, indicadors de pH i equilibri químic. Les antocianines són colorants naturals fàcilment obtinguts a partir d'espècies vegetals i tenen propietats indicadores de pH. L'experiment és simple, lúdic i no necessita cap infraestructura complicada, ja que el material de laboratori utilitzat pot ser substituït per material d'ús domèstic. L'experiment permet estudiar aquests conceptes en un enfocament contextualitzat i interdisciplinari, la qual cosa afavoreix el desenvolupament d'habilitats i competències, amb un enfocament CTS.We propose a versatile and accessible experiment that uses dry ice and fruit anthocyanin extracts to demonstrate and discuss concepts such as acidity, basicity, pH indicators and chemical equilibrium. It is possible because anthocyanins are natural colorants that have the pH indicator properties and are present in several vegetal species. The experiment introduces these concepts in a contextualized and interdisciplinary approach, which favors the development of skills and competencies, with STS focus
