Dyrbara experimenter : Införandet av modernare gatubelysning i Falu stad 1863-1888

Syftet med uppsatsen är att belysa en aspekt av Faluns omvandling till modern stad. Den del i denna modernisering som vidrörs i uppsatsen är införandet av elektrisk gatubelysning. Frågeställningarna i uppsatsen rör diskussionen som föregicks i stadsförvaltningen då man införde elektrisk gatubelysning i Falun och anledningarna till införandet av elektrisk belysning. Materialet som har använts för undersökningen är protokoll från stadsfullmäktige och drätselkammare i Falun under perioden 1863-1888. Gatubelysningen i Falun har sedan 1849 varit i stadsförvaltningens regi. Flera olika metoder av gatubelysning har sedan dess tillämpats och ännu fler metoder har diskuterats men aldrig kommit till stånd. Denna uppsats rör också anledningarna till gatubelysning i Falun vilka var flera utöver att få gatorna belysta för nattvandrarna. Stävjandet av brottsligheten var en av dem, estetiken en annan men även ett självändamål tycks också skönjbart. Byggandet av den moderna staden krävde moderna metoder och material. Elektriciteten som metod för belysning av gator var i högsta grad modernt och Falun var bland de första städerna som antog elektrisk gatubelysning i Sverige.

O processo de transcrição da Suíte 20 de Johann Jacob Froberger para violão solo

Este trabalho trata do processo de transcrição da Suíte 20 de J. J Froberger para violão solo. O objetivo geral é descrever o processo de transcrição com base em modelos de transcrição dos séculos XVII e XXI. A partir destas análises foi construído um referencial teórico para aplicação na transcrição da Suíte 20. A identificação dos elementos típicos do chamado stile brisé a partir do referencial foi essencial para o processo de transcrição da suíte 20, que se utilizou de vários procedimentos similares. No anexo deste artigo consta uma edição comparativa da versão original da Suíte 20 com a transcrição, bem como outra edição com a parte do violão solo e sugestões de execução.

Reptilia, Squamata, Dipsadidae, Xenodontinae, Taeniophallus brevirostris (Peters, 1863): distribution extension and new state record.

Taeniophallus brevirostris is a dipsadid snake widely distributed in Amazon. Here we report a new Brazilian state record for the species, improving our knowledge of its geographic distribution. 0n 15 May of 2008, one female specimen was collected do Serra do Santo Expediot, Aripuana municipality, state of Mato Grosso, Brazil. This is the first record of this species for the state of Mato Grosso and extends its distribution ca. 300 kilometers from the nearest localities presented in literature.

Differential benthic occupation by crabs in the Ubatuba bay, São Paulo, Brazil

The goal of this work was to examine the occurrence of brachyurans in soft bottom sublittoral habitats and their association with some environmental factors. The relative abundance of crabs in two depth strata (from 4.5 to 9 m and from 9 to 18 m) was quantified. Crabs were collected with an otter-trawl with 3.7 m of mouth opening and 12-mm mesh in the cod end. Monthly sampling, consisted of a single trawl in each stratum during a 1-yr period, were carried out. Fifteen brachyuran and six anomuran species were found, including Callinectes ornatus Ordway, 1863; Callinectes danae Smith, 1869; Hepatus pudibundus (Herbst, 1785); Libinia spinosa H. Milne-Edwards, 1834; Persephona punctata (Linnaeus, 1758), and P. mediterranea (Herbst, 1794), which were the most abundant and frequent in the area. The most abundant swimming crabs in both strata were C. ornatus and C, dan(re. Size differences in C. ornatus were observed between strata, suggesting a spatial separation of juveniles and adult crabs.

Juvenile development of Callinectes ornatus Ordway, 1863 (Crustacea : Decapoda : Portunidae), from megalopae obtained in the neuston

The juvenile development of Callinectes ornatus was studied from megalopae collected in the neuston off Ubatuba, São Paulo State, Brazil. The animals were raised in the laboratory under constant temperature (25 +/- 1 degrees C), filtered sea water (35 parts per thousand) from the sampling location, and the natural photoperiod. Eleven stages of the juvenile phase were obtained. The main features of the first juvenile stage diagnostic of the species are: the number of segments in the antenna; number of setae on the exopod, endopod, basal endite and coxal endite of the maxilla, on the exopod, endopod, basal endite, coxal endite and epipod of the 1(st) maxilliped, and on the exopod, endopod and epipod of the 2(nd) maxilliped. Sexual dimorphism becomes apparent from the fourth juvenile stage onwards.

The CMS experiment at the CERN LHC

The Compact Muon Solenoid (CMS) detector is described. The detector operates at the Large Hadron Collider (LHC) at CERN. It was conceived to study proton-proton (and lead-lead) collisions at a centre-of-mass energy of 14 TeV (5.5 TeV nucleon-nucleon) and at luminosities up to 10(34)cm(-2)s(-1) (10(27)cm(-2)s(-1)). At the core of the CMS detector sits a high-magnetic-field and large-bore superconducting solenoid surrounding an all-silicon pixel and strip tracker, a lead-tungstate scintillating-crystals electromagnetic calorimeter, and a brass-scintillator sampling hadron calorimeter. The iron yoke of the flux-return is instrumented with four stations of muon detectors covering most of the 4 pi solid angle. Forward sampling calorimeters extend the pseudo-rapidity coverage to high values (vertical bar eta vertical bar <= 5) assuring very good hermeticity. The overall dimensions of the CMS detector are a length of 21.6 m, a diameter of 14.6 m and a total weight of 12500 t.

Fecundity of crab Hepatus-pudibundas (herbst, 1785) (crustacea, decapoda, calappidae) in Ubatuba (SP), Brazil

The egg number and the rate in which they are produced constitute important informations for the comprehension of the reproductive process. The egg number carried by a female crab is related to a body dimension (carapace width or length). These data are adjusted to a linear regression. The specimens of Ii. pudibundus were collected in Ubatuba region, Brazil during the period from January 1991 to July 1993. In this paper 30 females with eggs in the initial embryonic phase were used to estimate ther egg number. The mean fecundity obtained was 75,615 +/- 30,120 eggs/female/spawn. Although the H. pudibundus fecundity was not high, it can be inferred that the larval survival in nature should be large, because it is one of the most abundant crabs in the studied area.
