An Affordable, Pratical Eco-House

An eco-house or zero-energy house is not a new concept- houses with extremely low impact on their surroundings and good use of local resources have been around for centuries. This particular eco-house is designed to offer full modern services and comforts while consuming very low energy and few expensive building materials. Ideally, someone would be able to use this thesis as a blueprint for actual construction.

THE HOUSE OF JOANA DARK: DRAMA AND PRODUCTION

While discussing images of Our Lady and of the mothers and women of the Garden of Flowers (or "Devils' Hole"), a peripheral district of a city in the interior of Sao Paulo state, this paper intends to explore the specificity of dramatic aesthetics. Rather than depend upon the aesthetics of social drama, as discussed in the works of Victor Turner, the present paper deals with a concept of montage that is inspired by the cinema of Sergei Eisenstein in order to illuminate a selection of field notes... and, along with Eisenstein, Julia Kristeva, Walter Benjamin, Michael Taussig and Antonin Artaud. Wit regards to those readers interested in hearing what these women may have to say, caution is suggested, for the words of these women may ring in our ears as the sounds of musket shots

Comparison of fast-track diagnostics respiratory pathogens multiplex real-time RT-PCR assay with in-house singleplex assays for comprehensive detection of human respiratory viruses

Fast-track Diagnostics respiratory pathogens (FTDRP) multiplex real-time RT-PCR assay was compared with in-house singleplex real-time RT-PCR assays for detection of 16 common respiratory viruses. The FTDRP assay correctly identified 26 diverse respiratory virus strains, 35 of 41 (85%) external quality assessment samples spiked with cultured virus and 232 of 263 (88%) archived respiratory specimens that tested positive for respiratory viruses by in-house assays. Of 308 prospectively tested respiratory specimens selected from children hospitalized with acute respiratory illness, 270 (87.7%) and 265 (86%) were positive by FTDRP and in-house assays for one or more viruses, respectively, with combined test results showing good concordance (K=0.812, 95% CI = 0.786-0.838). Individual FTDRP assays for adenovirus, respiratory syncytial virus and rhinovirus showed the lowest comparative sensitivities with in-house assays, with most discrepancies occurring with specimens containing low virus loads and failed to detect some rhinovirus strains, even when abundant. The FTDRP enterovirus and human bocavirus assays appeared to be more sensitive than the in-house assays with some specimens. With the exceptions noted above, most FTDRP assays performed comparably with in-house assays for most viruses while offering enhanced throughput and easy integration by laboratories using conventional real-time PCR instrumentation.

The gastric caeca of pentatomids as a house for actinomycetes

Abstract Background Microbes are extensively associated with insects, playing key roles in insect defense, nutrition and reproduction. Most of the associations reported involve Proteobacteria. Despite the fact that Actinobacteria associated with insects were shown to produce antibiotic barriers against pathogens to the hosts or to their food and nutrients, there are few studies focusing on their association with insects. Thus, we surveyed the Actinobacteria diversity on a specific region of the midgut of seven species of stinkbugs (Hemiptera: Pentatomidae) known to carry a diversity of symbiotically-associated Proteobacteria. Results A total of 34 phylotypes were placed in 11 different Actinobacteria families. Dichelops melacanthus held the highest diversity with six actinobacteria families represented by nine phylotypes. Thyanta perditor (n = 7), Edessa meditabunda (n = 5), Loxa deducta (n = 4) and Pellaea stictica (n = 3) were all associated with three families. Piezodorus guildini (n = 3) and Nezara viridula (n = 3) had the lowest diversity, being associated with two (Propionibacteriaceae and Mycobacteriaceae) and one (Streptomyceataceae) families, respectively. Corynebacteriaceae and Mycobacteriaceae were the most common families with phylotypes from three different insect species each one. Conclusions Many phylotypes shared a low 16S rRNA gene similarity with their closest type strains and formed new phyletic lines on the periphery of several genera. This is a strong indicative that stinkbug caeca can harbor new species of actinobacteria, which might be derived from specific associations with the species of stinkbugs studied. Although the well-known role of actinobacteria as a source of biomolecules, the ecological features of these symbionts on the stinkbugs biology remain unknown.

A Review of the Brazilian NBR 15575 Standard: Applying the Simulation and Simplified Methods for Evaluating a Social House Thermal Performance

The new Brazilian ABNT NBR 15575 Standard (the ―Standard‖) recommends two methods for analyzing housing thermal performance: a simplified and a computational simulation method. The aim of this paper is to evaluate both methods and the coherence between each. For this, the thermal performance of a low-cost single-family house was evaluated through the application of the procedures prescribed by the Standard. To accomplish this study, the EnergyPlus software was selected. Comparative analyses of the house with varying envelope U-values and solar absorptance of external walls were performed in order to evaluate the influence of these parameters on the results. The results have shown limitations in the current Standard computational simulation method, due to different aspects: weather files, lack of consideration of passive strategies, and inconsistency with the simplified method. Therefore, this research indicates that there are some aspects to be improved in this Standard, so it could better represent the real thermal performance of social housing in Brazil.

La matematica fuzzy nell'ingegneria dei materiali. Applicazioni alla durevolezza e alla conservazione dei materiali in opera nei siti archeologici

La ricerca presentata è un’ampia esplorazione delle possibili applicazioni di concetti, metodi e procedure della Fuzzy Logic all’Ingegneria dei Materiali. Tale nuovo approccio è giustificato dalla inadeguatezza dei risultati conseguiti con i soli metodi tradizionali riguardo alla reologia ed alla durabilità, all’utilizzo di dati di laboratorio nella progettazione e alla necessità di usare un linguaggio (informatizzabile) che consenta una valutazione congiunta degli aspetti tecnici, culturali, economici, paesaggistici della progettazione. – In particolare, la Fuzzy Logic permette di affrontare in modo razionale l’aleatorietà delle variabili e dei dati che, nel settore specifico dei materiali in opera nel costruito dei Beni Culturali, non possono essere trattati con i metodi statistici ordinari. – La scelta di concentrare l’attenzione su materiali e strutture in opera in siti archeologici discende non solo dall’interesse culturale ed economico connesso ai sempre più numerosi interventi in questo nuovo settore di pertinenza dell’Ingegneria dei Materiali, ma anche dal fatto che, in tali contesti, i termini della rappresentatività dei campionamenti, della complessità delle interazioni tra le variabili (fisiche e non), del tempo e quindi della durabilità sono evidenti ed esasperati. – Nell’ambito di questa ricerca si è anche condotto un ampio lavoro sperimentale di laboratorio per l’acquisizione dei dati utilizzati nelle procedure di modellazione fuzzy (fuzzy modeling). In tali situazioni si è operato secondo protocolli sperimentali standard: acquisizione della composizione mineralogica tramite diffrazione di raggi X (XRD), definizione della tessitura microstrutturale con osservazioni microscopiche (OM, SEM) e porosimetria tramite intrusione forzata di mercurio (MIP), determinazioni fisiche quali la velocità di propagazione degli ultrasuoni e rotoviscosimetria, misure tecnologiche di resistenza meccanica a compressione uniassiale, lavorabilità, ecc. – Nell’elaborazione dei dati e nella modellazione in termini fuzzy, la ricerca è articolata su tre livelli: a. quello dei singoli fenomeni chimico-fisici, di natura complessa, che non hanno trovato, a tutt’oggi, una trattazione soddisfacente e di generale consenso; le applicazioni riguardano la reologia delle dispersioni ad alto tenore di solido in acqua (calci, cementi, malte, calcestruzzi SCC), la correlazione della resistenza a compressione, la gelività dei materiali porosi ed alcuni aspetti della durabilità del calcestruzzo armato; b. quello della modellazione della durabilità dei materiali alla scala del sito archeologico; le applicazioni presentate riguardano i centri di cultura nuragica di Su Monte-Sorradile, GennaMaria-Villanovaforru e Is Paras-Isili; c. quello della scelta strategica costituita dalla selezione del miglior progetto di conservazione considerando gli aspetti connessi all’Ingegneria dei Materiali congiuntamente a quelli culturali, paesaggistici ed economici; le applicazioni hanno riguardato due importanti monumenti (Anfiteatro e Terme a Mare) del sito Romano di Nora-Pula.
