Transcript (original grammar and spelling retained): My dear wife I take this time to inform you that I am well hoping that these few lines will Reach you and find you the same I shall in form you of all our Battles that we have had sence I left home we crossed in to Canada the 2 day of July and took fort Erie on the 3 day of July without loss of one man. We then marched down to Chipway eighteen miles below the Fort Erie we got there on the forth day and had our first battle on the 5 day our loss was not jistly known But the inemy loss was double to ours. The 6 day we started with the 2 Brigade to make a bridge a crost the crick two miles a bove the fort in Building the Bridge the inemy Brought up their Canon and playd upon us with their artiliery a bout two hours We drove them from the fort our loss was none the inemy loss was nineteen ciled dead on the ground we then marched to Queenston when we got thare our inemy had fledfrom the fort we then remained thair to Queenston ten days then we marched down to Fort George But that caurdly Chaney did not a rive with the fleet so we had to return back to Queenston thare was a bout six hundred militia formed on the heights of land thay fired up on us from their pickets and retreated to the mane body our flankers ciled and wounded and took about twenty before they got to the Maine body we then marched up the hill they gave us two firs but did not damage and then retreated from the field we stayed there one knight and then marched to Chipway and stayed there one night and the next day just as the sun set the first Brigade marched up in order to give them Battle a bout two miles from the Crick and began the Battle the 2 Brigade has to March up to the Niagara path and ingaged them we charged up on their artlery and took all their Canon Miller commanded the four companys that charged....the battles lasted three hours and forty minutes our loss was about 8 hundred cild and wounded our inemies loss was a bout fourteen hundred cild and wounded the next morning we Marched up in order to give them Battle a gin but thay was afraid to ingage us we then marched to Fort Erie and went to fortiffing and made a strong place the inemy folered us up and Began to cananade and held it fifty three days thay a tacked the fort the fifteenth of august thay atacked a bout one hiour be fore day Light we saw them and Blue up our maggerzean & two hundred of our inemy our loss wasa bout forty cild and wounded and our inemy loss was a bout one thousand on the 7 Day of September we atacked them and took their batteries and Broke all their canon and drove them from the field our loss was a Bout two hundred cild and wounded our inemy loss was a Bout 8 hundred cild and wounded...we crossed in to Canada with five thousand and came out with fifteen hundred we then Marched to Sackett’s harbor....am well and harty for the present....a bout comming home it uncarting for there is not any....given this winter as yet But I shall try to Come home if I Can But if I Cant I want you should take good car of the Phiddness[?] I have not Received any Money as yet But soon as I do receive some I send some home.

Observations de pulsateurs compacts à l'aide de la caméra Mont4K CCD

Les pulsateurs compacts sont des étoiles présentant des variations intrinsèques de luminosité dont les gravités de surface sont supérieures à 100,000 cm/s² On retrouve parmi ces objets deux familles des sous-naines chaudes de type B (sdB) pulsantes et quatre familles distinctes de naines blanches pulsantes. Dans le but d'observer les pulsations de tels objets pour ensuite analyser leur propriétés grâce à l'astéroséismologie, l'Université de Montréal, en collaboration avec le Imaging Technology Laboratory (ITL - University of Arizona), a développé la caméra Mont4K (Montreal4K) CCD qui est, depuis le printemps 2007, le principal détecteur employé au télescope Kuiper de 1.55 m du Mt Bigelow (Steward Observatory, University of Arizona). à l'aide de ce montage, des observations ont été menées pour quelques-uns de ces pulsateurs compacts. La première cible fut HS 0702+6043, un pulsateur hybride. Une importante mission pour cet objet, réalisée du 1er novembre 2007 au 14 mars 2008, a permis d'identifier 28 modes de pulsations pour cet objet en plus de mettre en évidence pour certains de ces modes d'importantes variations d'amplitude. Deux autres cibles furent les naines blanches pulsantes au carbone de type « Hot DQ » SDSS J220029.08-074121.5 et SDSS J234843.30-094245.3. Il fut possible de montrer de façon indirecte la présence d'un fort champ magnétique à la surface de J220029.08-074121.5 grâce à la présence de la première harmonique du mode principal. En outre, pour ces deux cibles, on a pu conclure que celles-ci font bel et bien partie de la classe des naines blanches pulsantes au carbone.

“Population Characteristics, Fishery and Post larval distribution of Macrobrachium rosenbergii (de Man) and M. idella (Hilgendorf) of Vembanad lake”

Macrobrachium rosenbergii (de Man) and M.ide77a (Hilgendorf) form two commercially important Palaemonid prawns of the Vembanad lake (9 28' and 10 10’ N and 76 13' and 76 31' E). Both of them were known to have contributed to a very lucrative fishery during the sixties, however, in recent years these natural resources have badly depleted owing to the impact of many man made alterations brought about in the ecosystem such as habitat reduction, physical obstruction imposed in the migratory pathway of these species, pollution hazards, etc,. Changed environmental conditions and increased fishing pressures caused persistent alterations in the stock size of these prawns during the past so many years, however, no serious attempt was made to monitor the stock size from time to time and also to bring out the resource characteristics. Though, the morphotypic differentiation in grow out male population of M.rosenbergii has been documented, no similar studies were conducted with regard to natural male and female population. Based on the data collected during fishery cruise surveys conducted in Vembanad lake from March '94 to February '96, population characteristics. postlarval distribution, fishery and population dynamics of M.rosenbergii and M.ide77a of the lake were studied in detail.

Proposta d’una xarxa d’espais naturals protegits a Andorra

Andorra és un microestat situat al bell mig Pirineus, històricament la dinàmica de la població i els seus costums han estat lligats a l’entorn i als recursos que aquest els ofereix. A partir dels anys 50 però, Andorra pateix un increment demogràfic i un canvi en les activitats que s’hi desenvolupen, amb un descens del pes del sector primari i un increment de les activitats del terciari. Aquest fet porta a l'expansió dels nuclis de població i un augment de l’oferta de serveis per a potenciar el turisme i el comerç , augmentant així la pressió sobre el medi, que es veu incrementada per la manca de control i de regulació en l’àmbit de l’ordenament territorial. En els últims anys però, s’han realitzat diferents actuacions que han intentat esmenar aquestes mancances, creant, per exemple, legislació d’ordenació del territori i urbanisme (2001), i els Parcs Naturals de la Vall de Sorteny (1999) i del Comapedrosa (2006). Tot i això, és evident que en l’actualitat existeixen encara moltes mancances que cal resoldre urgentment. Per aquest motiu es fa la la proposta d’una xarxa d’espais naturals protegits a Andorra i la creació d’unes directrius que en facilitin la seva gestió. Situant Andorra a l’alçada d’altres països europeus en matèria de protecció del medi natural, i proporcionant unes bases que permetin la gestió unificada d’aquesta xarxa.

The response of tropospheric circulation to perturbations in lower-stratospheric temperature

A multiple regression analysis of the NCEP-NCAR reanalysis dataset shows a response to increased solar activity of a weakening and poleward shift of the subtropical jets. This signal is separable from other influences, such as those of El Nino-Southern Oscillation (ENSO) and the North Atlantic Oscillation (NAO), and is very similar to that seen in previous studies using global circulation models (GCMs) of the effects of an increase in solar spectral irradiance. The response to increased stratospheric (volcanic) aerosol is found in the data to be a weakening and equatorward shift of the jets. The GCM studies of the solar influence also showed an impact on tropospheric mean meridional circulation with a weakening and expansion of the tropical Hadley cells and a poleward shift of the Ferrel cells. To understand the mechanisms whereby the changes in solar irradiance affect tropospheric winds and circulation, experiments have been carried out with a simplified global circulation model. The results show that generic heating of the lower stratosphere tends to weaken the subtropical jets and the tropospheric mean meridional circulations. The positions of the jets, and the extent of the Hadley cells, respond to the distribution of the stratospheric heating, with low-latitude heating forcing them to move poleward, and high-latitude or latitudinally uniform heating forcing them equatorward. The patterns of response are similar to those that are found to be a result of the solar or volcanic influences, respectively, in the data analysis. This demonstrates that perturbations to the heat balance of the lower stratosphere, such as those brought about by solar or volcanic activity, can produce changes in the mean tropospheric circulation, even without any direct forcing below the tropopause.

Look up, look around: is there anything different about team-level OCB in China?

Ethical leadership has been widely identified as the key variable in enhancing team-level organizational citizenship behavior (team-level OCB) in western economic and business contexts. This is challenged by empirical evidence in China and findings of this study. Our study examined the relationship between ethical leadership, organizational ethical context (ethical culture and corporate ethical values) and team-level OCB. Team-level data has been collected from 57 functional teams in 57 firms operating in China. The findings suggest that although ethical leadership is positively associated with team-level OCB, ethical context positively moderates the relationship between ethical leadership and team-level OCB. The higher ethical context is found to be, the greater is the (positive) effects of ethical leadership on team-level OCB and the opposite holds true when ethical context is low. Key implications are discussed on the role of contextual ethics for team level OCB, while managerial implications include how non-Chinese firms could improve team-level OCB in the Chinese business context.

Flow injection amperometric determination of hydrogen peroxide in household commercial products with a ruthenium oxide hexacyanoferrate modified electrode

Hydrogen peroxide was determined in oral antiseptic and bleach samples using a flow-injection system with amperometric detection. A glassy carbon electrode modified by electrochemical deposition of ruthenium oxide hexacyanoferrate was used as working electrode and a homemade Ag/AgCl (saturated KCl) electrode and a platinum wire were used as reference and counter electrodes, respectively. The electrocatalytic reduction process allowed the determination of hydrogen peroxide at 0.0 V. A linear relationship between the cathodic peak current and concentration of hydrogen peroxide was obtained in the range 10-5000 mu mol L(-1) with detection and quantification limits of 1.7 (S/N = 3) and 5.9 (S/N = 10) mu mol L(-1), respectively. The repeatability of the method was evaluated using a 500 mu mol L(-1) hydrogen peroxide solution, the value obtained being 1.6% (n = 14). A sampling rate of 112 samples h(-1) was achieved at optimised conditions. The method was employed for the quantification of hydrogen peroxide in two commercial samples and the results were in agreement with those obtained by using a recommended procedure.

Direct determination of iron in sand using solid sampling graphite furnace atomic absorption spectrometry

A fast and reliable method for the direct determination of iron in sand by solid sampling graphite furnace atomic absorption spectrometry was developed. A Zeeman-effect 3-field background corrector was used to decrease the sensitivity of spectrometer measurements. This strategy allowed working with up to 200 mu g of samples, thus improving the representativity. Using samples with small particle sizes (1-50 mu m) and adding 5 mu g Pd as chemical modifier, it was possible to obtain suitable calibration curves with aqueous reference solutions. The pyrolysis and atomization temperatures for the optimized heating program were 1400 and 2500 degrees C, respectively. The characteristic mass, based on integrated absorbance, was 56 pg, and the detection limits, calculated considering the variability of 20 consecutive measurements of platform inserted without sample was 32 pg. The accuracy of the procedure was checked with the analysis of two reference materials (IPT 62 and 63). The determined concentrations were in agreement with the recommended values (95% confidence level). Five sand samples were analyzed, and a good agreement (95% confidence level) was observed using the proposed method and conventional flame atomic absorption spectrometry. The relative standard deviations were lower than 25% (n = 5). The tube and boat platform lifetimes were around 1000 and 250 heating cycles, respectively.

Musikens betydelse för film : En undersökning om musikens inverkan i film

Foric, Armin - Musikens betydelse för film – En undersökning om musikens inverkan i film (Högskolan Dalarna 2009) är en uppsats som syftar till att försöka förstå hur bakgrundsmusik påverkar film. Genom att använda sig av ett och samma klipp men med olika bakgrundsmusik vill jag försöka förstå hur musik påverkar uppfattningen av en film. Syftet är också att jämföra min och Rasmus Wedins uppsats som heter ”Ljudet är halva upplevelsen... Minst!” (Högskolan Dalarna 2006) på de punkter där våra frågor matchar varandra.Den viktiga huvudfrågan är:– Hur påverkas uppfattningen av en film genom musik?Sekundära frågeställningar: – Hur viktig är bakgrundsmusiken för uppfattningen om en films handling? – Hur tolkar man filmens handling beroende på vad för musik man hör, eller inte hör? – Hur tolkar åskådaren karaktärens roll i filmen beroende på vad för musik de hör? – Hur påverkar antalet film/vecka den tolkning man har? – Hur påverkar en favorit genre uppfattningen åskådaren har?Jag valde att musiklägga de två första minuterna från filmen ”Under ytan finns havet” producerad av elever på högskolan dalarna i tre olika versioner. Jag valde att först musiklägga en version i drama, den andra i komedi och den tredje i skräck utförande, därefter gjorde jag en tittarundersökning med frågor på enkäter som försökspersonerna fick svara på.Efter att ha samlat in material och sammanställt frågorna så blir mina frågeställningar besvarade. Vi kan tydligt se hur musiken påverkar en film på alla sätt, och inte bara upplevelsen

Purificação e caracterização da bacteriocina cereína 8A, produzida por uma linhagem de Bacillus cereus

Foi estudada uma bacteriocina produzida por uma linhagem de B. cereus 8A, isolado de solo da região Sul do Brasil. Na primeira etapa de estudo determinaram-se as condições básicas de produção de bacteriocina com amplo espectro de ação denominada de Cereína 8A. Observou-se que durante a fase estacionária ocorre o máximo da sua produção, iniciando sua síntese no final da fase exponencial. As condições de maior produção foram a 30º C, agitação e contínua e numa faixa de pH de 7,0-8,5. A bacteriocina bruta inibiu várias bactérias indicadoras, como Listeria monocytogenes, Clostridium perfringens e Bacillus cereus. O teste de termoestabilidade mostrou a perda de atividade quando submetida a uma temperatura a partir de 87º C. Verificou-se a resistência da bacteriocina bruta frente à tripsina e papaína, mas não frente à proteinase K e pronase E. B. cereus e L. monocytogenes foram utilizadas como bactérias indicadoras para a determinação do modo de ação, após a determinação da dose bactericida de 200 UA mL-1 e 400 UA mL-1 respectivamente. A Cereína 8A demonstrou uma ação inibidora em culturas de Escherichia coli e Salmonella Enteritidis, quando tratadas com EDTA. A atividade esporicida foi observada contra esporos de B. cereus após tratamento com 400 UA ml -1. A análise da biomassa de L. monocytogenes e B. cereus após tratamento com a Cereína 8A, através da espectrofotometria de infravermelho determinou alteração no perfil, correspondente à fração dos ácidos graxos da membrana celular bacteriana. A substância peptídica foi separada por meio da precipitação com sulfato de amônio, extração com 1-butanol e aplicação em coluna de cromatografia por troca iônica tipo Q-Sepharose. A Cereína 8A purificada mostrou maior sensibilidade a proteases e ao calor e um peso molecular de aproximadamente 26 kDa. O espectro ultravioleta foi típico de um polipeptídeo e o espectro de infravermelho indica presença de grupamentos NH, acil e ligações peptídicas na sua estrutura. Uma hipótese do mecanismo de ação seria a desestruturação da membrana celular pela abertura de poros.
