Adrien-Marie Legendre (1752-1833) e suas obras em Teoria dos Números

The present thesis is an analysis of Adrien-Marie Legendre s works on Number Theory, with a certain emphasis on his 1830 edition of Theory of Numbers. The role played by these works in their historical context and their influence on the development of Number Theory was investigated. A biographic study of Legendre (1752-1833) was undertaken, in which both his personal relations and his scientific productions were related to certain historical elements of the development of both his homeland, France, and the sciences in general, during the 18th and 19th centuries This study revealed notable characteristics of his personality, as well as his attitudes toward his mathematical contemporaries, especially with regard to his seemingly incessant quarrels with Gauss about the priority of various of their scientific discoveries. This is followed by a systematic study of Lagrange s work on Number Theory, including a comparative reading of certain topics, especially that of his renowned law of quadratic reciprocity, with texts of some of his contemporaries. In this way, the dynamics of the evolution of his thought in relation to his semantics, the organization of his demonstrations and his number theoretical discoveries was delimited. Finally, the impact of Legendre s work on Number Theory on the French mathematical community of the time was investigated. This investigation revealed that he not only made substantial contributions to this branch of Mathematics, but also inspired other mathematicians to advance this science even further. This indeed is a fitting legacy for his Theory of Numbers, the first modern text on Higher Arithmetic, on which he labored half his life, producing various editions. Nevertheless, Legendre also received many posthumous honors, including having his name perpetuated on the Trocadéro face of the Eiffel Tower, which contains a list of 72 eminent scientists, and having a street and an alley in Paris named after him

Mini Nutritional Assessment predicts gait status and mortality 6 months after hip fracture.

The aim of the present study was to evaluate the Mini Nutritional Assessment (MNA), the Nutritional Risk Screening (NRS) 2002 and the American Society of Anesthesiologists Physical Status Score (ASA) as predictors of gait status and mortality 6 months after hip fracture. A total of eighty-eight consecutive patients over the age of 65 years with hip fracture admitted to an orthopaedic unit were prospectively evaluated. Within the first 72 h of admission, each patient's characteristics were recorded, and the MNA, the NRS 2002 and the ASA were performed. Gait status and mortality were evaluated 6 months after hip fracture. Of the total patients, two were excluded because of pathological fractures. The remaining eighty-six patients (aged 80·2 (sd 7·3) years) were studied. Among these patients 76·7 % were female, 69·8 % walked with or without support and 12·8 % died 6 months after the fracture. In a multivariate analysis, only the MNA was associated with gait status 6 months after hip fracture (OR 0·773, 95 % CI 0·663, 0·901; P= 0·001). In the Cox regression model, only the MNA was associated with mortality 6 months after hip fracture (hazard ratio 0·869, 95 % CI 0·757, 0·998; P= 0·04). In conclusion, the MNA best predicts gait status and mortality 6 months after hip fracture. These results suggest that the MNA should be included in the clinical stratification of patients with hip fracture to identify and treat malnutrition in order to improve the outcomes.

The plants by Daniel Rolander (c. 1723-1793) in Diarium Surinamicum (1754-1765) and herbaria

The manuscripts of Diarium Surinamicum by Daniel Rolander practically remained ignored and unpublished for over 240 years, till the recent publication of its translation into English, which occurred in 2008. In this, the names of species described and/or cited by Rolander were faithfully retained, hence preserving the indication of them without authorship, for the vast majority. In the present work, all the names of plants that were treated by Rolander in his journal, about 664, including by tradition the fungi and algae, are contextualised in relation to the authorship, reference to the publication of the protologue, pagination of citations/descriptions in the manuscripts and in the published translation, indication of probable misidentifications with possible alternative names, vernacular names, and related literature. Additionally, we searched for the vouchers collected by Rolander, scattered in several herbaria, which have been linked to the probable names and descriptions in the diary. Given the considerable time till the publication of these names, and by the lack of indication of their nomenclatural types in the English version, the great majority of the new species described by Rolander, which would have priority if published in due time, became invalid names according to the ICN. Nevertheless, the list of Rolandrian species here presented, from his work that has finally taken a place in the history of natural sciences, shows that he was also a competent botanist, besides being a skilled entomologist, having recognised and detailedly described many of the Surinamese plants hitherto unknown to science.

Nutrient distributions over the Southwestern South Atlantic continental shelf from Mar del Plata (Argentina) to Itajai (Brazil): Winter-summer aspects

Nutrient distributions observed at some depths along the continental shelf from 27 degrees 05`S (Brazil) to 39 degrees 31`S (Argentina) in winter, 2003 and summer, 2004 related to salinity and dissolved oxygen (mL L-1) and saturation (%) data showed remarkable influences of fresh water discharge over the coastal region and in front of the La Plata estuary. In the southern portion of the study area different processes were verified. Upwelling processes caused by ocean dynamics typical of shelf break areas, eddies related to surface dynamics and regeneration processes confirmed by the increase of nutrients and the decrease of dissolved and saturation oxygen data were verified. High silicate concentrations in the surface waters were identified related to low salinities (minimum of 21.22 in winter and 21.96 in summer), confirming the importance of freshwater inputs in this region, especially in winter. Silicate concentration range showed values between 0.00 and 83.52 mu M during winter and from 0.00 to 41.16 mu M during summer. Phosphate concentrations worked as a secondary trace of terrestrial input and their values varied from 0.00 to 3.30 mu M in winter and from 0.03 to 2.26 mu M in summer; however, in shallow waters, phosphate indicated more clearly the fresh water influence. The most important information given by nitrate concentrations was the presence of water from SACW upwelling that represents a new source of nutrients for marine primary production. Nitrate maximum values reached 41.96 M in winter and 33.10 mu M in summer. At a depth similar to 800m, high nitrate, phosphate and silicate concentrations were related to Malvinas Current Waters, Subantarctic Shallow Waters and Antarctic Atlantic Intermediate Waters (AAIW). Dissolved oxygen varied from 3.41 to 7.06 mL L-1 in winter and from 2.65 to 6.85 mL L-1 in summer. The percentage of dissolved oxygen saturation in the waters showed values between 48% and 113% in winter and from 46% to 135% in summer. The most important primary production was verified in the summer, and situations of undersaturation were mainly observed below 50 m depth and at some points near the coast. The anti-correlation between nutrients and dissolved oxygen which showed evident undersaturation also revealed important potential sites of remineralization processes. The nutrient behaviours showed some aspects of the processes that occur over the Southwestern South Atlantic continental shelf and in their land-sea interfaces between Mar del Plata and Itajai.

Blood alcohol levels in suicide by hanging cases in the state of Sao Paulo, Brazil

Suicide is one of the main causes of violent death worldwide, and has become a public health issue. Since alcohol consumption is associated with the increase in the number of suicides and hanging is one of the main methods used worldwide, the present study consists of an epidemiological analysis of BACs in victims of suicide by hanging autopsied in the State of Sao Paulo, Brazil. The objective of the present work was to establish an epidemiological profile and evaluate blood alcohol concentrations in victims of suicide by hanging in the State of Sao Paulo, Brazil, in the year of 2007. A cross-sectional retrospective study was conducted by collection of secondary data from autopsy reports of victims of hanging. According to the present study, positive results for alcohol were higher in male victims, but the mean BAC was higher in women. (C) 2012 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Una grande narrazione del capitalismo: potere e scienze sociali nel pensiero politico di Daniel Bell

Questa tesi punta a ricostruire il pensiero politico di Bell tra il secondo dopoguerra e la metà degli anni Settanta. In tale arco cronologico, la riflessione politica di Bell si profila, per usare una formula di Jean-François Lyotard, come una «grande narrazione» del capitalismo. Nel complesso, cioè, l’opera di Bell appare come una storia sociologica del capitalismo, che nella fine delle ideologie registra l’apogeo del fordismo e, in seguito, ne mette in luce le trasformazioni in senso post-industriale, indagando le ricadute che tali mutamenti implicano sul piano dei rapporti di potere e della legittimazione del sistema. Nell’ottica di Bell, pertanto, il capitalismo non costituisce soltanto un sistema economico, ma la forma specifica attraverso cui si dispiega la società nel suo complesso, attivando una serie di rapporti di potere mediante i quali gli individui vengono coordinati e subordinati. Una siffatta concezione del capitalismo agisce immediatamente la questione del potere e solleva un interrogativo a esso connesso: «che cosa tiene insieme una società?». Una domanda che attraversa la traiettoria intellettuale di Bell e, sia pure declinata mediante una terminologia sociologica, riflette in realtà l’ambizione delle scienze sociali di farsi teoria politica. Esse si presentano quindi come teoria politica della modernità, nella misura in cui distinguono il potere sociale dal potere politico e, al tempo stesso, instaurano tra i due poli una tensione dialettica produttiva. Mettendo a fuoco la concettualizzazione del potere nell’opera di Bell si analizzeranno le mutazioni nel rapporto tra Stato e società negli Stati Uniti durante la Golden Age del capitalismo. In particolare, si metterà in luce nella grande narrazione di Bell l’ascesa e il declino di un ordine istituzionale che, alla metà degli anni Settanta, appare percorso da molteplici tensioni politiche e sociali che preannunciano l’avvento dell’età globale e il bisogno di una nuova “scala” di governo.

[Persistent neutropenia]

We report the case of a 72-old patient with persistent neutropenia diagnosed during investigation of sialadenitis. Further examination led to the diagnosis of immune neutropenia and systemic lupus erythematosus. Anamnesis and the clinical course made initial diagnosis of drug-induced lupus erythematosus implausible. Steroid trial was done, followed by maintenance therapy, with good control of symptoms.

Polyneuropathies--short and sweet

Complaints of sensory loss and (painful) tingling in a stocking distribution are not uncommon in primary care. These symptoms are especially troublesome while getting asleep. Characteristically, ankle tendon reflexes and vibration perception are diminished. These are the hallmarks of distal-symmetric sensory polyneuropathy (PNP), with diabetes mellitus being the most common cause in our patient population. PNP presents itself only after years of suboptimal glycemic control in diabetes type 1. In patients with type 2, symptoms of PNP can precede formal diagnosis of diabetes! In this mini-review we present an algorithm for diagnosis and management of PNP's in general practice.
