Sociable widow spiders? Evidence of subsociality in Latrodectus Walckenaer, 1805 (Araneae, Theridiidae)

A first case of subsociality is reported for the genus Latrodectus. Individuals were found sharing the same web and feeding together. In captivity they showed mutual tolerance and communal feeding. This finding is remarkable for two reasons. First, widow spiders, even compared with other spiders, are famously aggressive and cannibalistic so that social behavior in the genus was unexpected. Second, the genus nests outside the ""Anelosimus + lost colulus"" clade where all the other social theridiids are found.

A responsabilidade enunciativa em Itinéraire d un Voyage en Allemagne

Nossa pesquisa se circunscreve nos estudos da Análise Textual dos Discursos, proposta pelo linguista Jean-Michel Adam. Nosso foco principal está voltado para o fenômeno da Responsabilidade Enunciativa (doravante RE). Além das categorias de análise para se estudar a RE, conforme Adam (2008, 2010, 2011), também seguiremos outros estudiosos no assunto, como Oswald Ducrot (1984), os teóricos Teoria Escandinava da Polifonia Linguística, (2004), Zlatka Guentchéva (1994), Jean-Pierre Desclés (2009) e Jacqueline Authier-Revuz (1998, 2004). Utilizaremos os pressupostos apresentados por Alain Rabatel (2004, 2008, 2009, 2010), sobretudo, no que concerne às noções de locutor/enunciador, ponto de vista ou vozes que podem ser encontradas em um texto. Para tanto, analisaremos um relato de viagem, Itinéraire d un Voyage en Allemagne (doravante Itinéraire), escrito no século XIX por Nísia Floresta, uma norte-rio-grandense que fez residência na França e ficou conhecida como uma das primeiras feministas do Brasil. O relato de viagem é um gênero diferenciado para se analisar a RE, sobretudo o Itinéraire, pois nele também podemos encontrar a presença de outros gêneros, quais sejam: epistolar e autobiográfico. Assim, percorreremos, primeiramente, algumas abordagens sobre gêneros de discurso, utilizando-nos, principalmente, dos pressupostos de Mikhail Bakhtin (1992, 2003), Geneviève Bordet (2011), Jean Michel Adam (2011) e Luiz Antônio Marcuschi (2008) e, posteriormente, apresentaremos algumas características que envolvem os gêneros citados. Por fim, para análise dos dados, estamos seguindo a abordagem qualitativa de natureza interpretativista. Nossa pesquisa comprovou que o Itinéraire apresenta muitas marcas de assunção da RE, mas que, apesar de Nísia Floresta ser locutora e enunciadora, é possível encontrar marcas de não assunção da RE, ou seja, outros PDV

Using Universal Line Model (ULM) for Representing Electromagnetic Transients in Three-Phase Transmission Lines

The second-order differential equations that describe the polyphase transmission line are difficult to solve due to the mutual coupling among them and the fact that the parameters are distributed along their length. A method for the analysis of polyphase systems is the technique that decouples their phases. Thus, a system that has n phases coupled can be represented by n decoupled single-phase systems which are mathematically identical to the original system. Once obtained the n-phase circuit, it's possible to calculate the voltages and currents at any point on the line using computational methods. The Universal Line Model (ULM) transforms the differential equations in the time domain to algebraic equations in the frequency domain, solve them and obtain the solution in the frequency domain using the inverse Laplace transform. This work will analyze the method of modal decomposition in a three-phase transmission line for the evaluation of voltages and currents of the line during the energizing process.

Freno per ULM

La rivisitazione del design di esistenti versioni di freno consente una sensibile riduzione sia del peso complessivo della singola ruota sia dell'ingombro assiale. La circostanza di singola frenata in un tempo relativamente breve permette l'adozione di formule semplificate per l'analisi di temperatura.

Mortality and morbidity in the city of Bern, Switzerland, 1805-1815 with special emphasis on infant, child and maternal deaths

This article contributes to the research on demographics and public health of urban populations of preindustrial Europe. The key source is a burial register that contains information on the deceased, such as age and sex, residence and cause of death. This register is one of the earliest compilations of data sets of individuals with this high degree of completeness and consistency. Critical assessment of the register's origin, formation and upkeep promises high validity and reliability. Between 1805 and 1815, 4,390 deceased inhabitants were registered. Information concerning these individuals provides the basis for this study. Life tables of Bern's population were created using different models. The causes of death were classified and their frequency calculated. Furthermore, the susceptibility of age groups to certain causes of death was established. Special attention was given to causes of death and mortality of newborns, infants and birth-giving women. In comparison to other cities and regions in Central Europe, Bern's mortality structure shows low rates for infants (q0=0.144) and children (q1-4=0.068). This could have simply indicated better living conditions. Life expectancy at birth was 43 years. Mortality was high in winter and spring, and decreased in summer to a low level with a short rise in August. The study of the causes of death was inhibited by difficulties in translating early 19th century nomenclature into the modern medical system. Nonetheless, death from metabolic disorders, illnesses of the respiratory system, and debilitation were the most prominent causes in Bern. Apparently, the worst killer of infants up to 12 months was the "gichteren", an obsolete German term for lethal spasmodic convulsions. The exact modern identification of this disease remains unclear. Possibilities such as infant tetanus or infant epilepsy are discussed. The maternal death rate of 0.72% is comparable with values calculated from contemporaneous sources. Relevance of childbed fever in the early 1800s was low. Bern's data indicate that the extent of deaths related to childbirth in this period is overrated. This research has an explicit interdisciplinary value for various fields including both the humanities and natural sciences, since information reported here represents the complete age and sex structure of a deceased population. Physical anthropologists can use these data as a true reference group for their palaeodemographic studies of preindustrial Central Europe of the late 18th and early 19th century. It is a call to both historians and anthropologists to use our resources to a better effect through combination of methods and exchange of knowledge.
