The Dominion Express Building : a cultural investigation
The Dominion Express Building, situated in the heart of Old Montreal's business district, was commissioned by the Dominion Express Company and designed by the architects Edward and William Sutherland Maxwell in 1912. The building was, in its conservative styling and modest size, a fine example of what has been called the Edwardian Commercial Style. Though traditional architectural history would minimize the importance of the Dominion Express Building, this study intends to reassert, through method developed by Cultural Studies, the building's significance in Canadian history. By extending the focus of architectural historical method to include a variety of cultural readings a rich understanding of the role that commercial architecture played in Canadian history during this period can be achieved. Additionally, this study broadens understanding of the culture of the "Square Mile" in the first decades of this century
Музыка в романе Евгения Водолазкина Брисбен
The author of the article examines the role of music in Evgeny Vodolazkin’s novel Brisbane, analyzing individual manifestations of the widely understood intermediacy. The musical code of the text is expressed in audibility of the sounds the world of the novel is filled with, and in musical ecphrasis (the profession of the protagonist, professional vocabulary and slang, references to musical compositions; descriptions of the world of music through the prism of the characters’ perception). These techniques perform plot and semantic functions, combine two equal plot plans, and constitute the image of the protagonist and other important characters. Fragments with musical ecphrasis have a vivid narrative, emotionally saturated (“moments of explosion”). The main emotional codes (or affects) find expression in the selection of musical compositions that assert the dramatic direction of the narrative. Music in the novel expresses the hero’s inner state, his relationship to the world, and symbolizes the metaphysical breakthrough experienced by the hero: from love and sound, to silence and eternity.The author of the article examines the role of music in Evgeny Vodolazkin’s novel Brisbane, analyzing individual manifestations of the widely understood intermediacy.

Fatores que afetam na motivação dos funcionários e seus aspectos no atendimento do cliente
Orientador: Pedro Jose Steiner NetoMonografia(Especialização) - Universidade Federal do Paraná,Setor de Ciências Sociais Aplicadas, Curso de Especialização em Estratégia e Gestão EmpresarialResumo: Sabe-se que a motivação humana é fator de fundamental importância para o rendimento da produção laboral, com isso, frente às constantes mudanças nas organizações contemporâneas, constatou-se a necessidade de se estudar os fatores que afetam na motivação dos funcionários bancários, especificamente os caixas, tendo em vista as diversas teorias, os diversos modelos de comportamento humano e como se operacionalizam tais funções perante a clientela. Com isso, entendeu-se necessária pesquisar o desenvolvimento pessoal do indivíduo no setor bancário, considerando o trabalho bancário e sua evolução, as formas de viabilização do novo processo de produção já transformada, em observância aos paradigmas que impedem ou facilitam melhor o desenvolvimento do colaborador, sendo a atitude um requisito preponderante para melhor compreender as ações conflituosas dos caixas bancários. Desta forma, constata-se que o conhecimento tanto individual quanto organizacional funcionam como fonte motivadora, respaldando-se em diferencial na organização. Doravante, os aspectos que envolvem a aprendizagem incluem o tempo, o espaço e as pessoas, de modo a ampliar a capacitação do homem no contexto da atividade. Por fim, o trabalho busca uma abordagem para as estratégias motivacionais utilizadas para a promoção do desenvolvimento interpessoal, gerencial e organizacional, com base no pressuposto de que conhecimento e poder

Comparison of a novel real-time SonixGPS needle-tracking ultrasound technique with traditional ultrasound for vascular access in a phantom gel model
ObjectiveUltrasound-guided percutaneous vascular access for endovascular procedures is well established in surgical practice. Despite this, rates of complications from venous and arterial access procedures remain a significant cause of morbidity. We hypothesized that the use of a new technique of vascular access using an ultrasound with a novel needle-guidance positioning system (GPS) would lead to improved success rates of vascular puncture for both in-plane and out-of-plane techniques compared with traditional ultrasound.MethodsA prospective, randomized crossover study of medical students from all years of medical school was conducted using a phantom gel model. Each medical student performed three ultrasound-guided punctures with each of the four modalities (in-plane no GPS, in-plane with GPS, out-of-plane no GPS, out-of-plane with GPS) for a total of 12 attempts. The success or failure was judged by the ability to aspirate a simulated blood solution from the model. The time to successful puncture was also recorded. A poststudy validated NASA Task Load Index workload questionnaire was conducted to assess the student's perceptions of the two different techniques.ResultsA total of 30 students completed the study. There was no significant difference seen in the mean times of vascular access for each of the modalities. Higher success rates for vascular access using the GPS for both the in-plane (94% vs 91%) and the out-of-plane (86% vs 70%) views were observed; however, this was not statistically significant. The students perceived the mental demand (median 12.0 vs 14.00; P = .035) and effort to be lower (mean 11.25 vs 14.00; P = .044) as well as the performance to be higher (mean 15.50 vs 14.00; P = .041) for the GPS vs the traditional ultrasound-guided technique. Students also perceived their ability to access vessels increased with the aid of the GPS (7.00 vs 6.50; P = .007). The majority of students expressed a preference for GPS (26/30, 87%) as opposed to the traditional counterpart.ConclusionsUse of the novel SonixGPS needle-tracking ultrasound system (UltraSonix, Richmond, BC, Canada) was not associated with a higher success rate of vascular puncture compared with the traditional ultrasound-guided technique. Assessment of mental task load significantly favored the use of the ultrasound GPS over the traditional ultrasound technique
Repair and Manufacture of High Performance Products for Medicine and Aviation with Laser Technology
High performance products used for special purposes in medicine and aviation are often manufactured from advanced materials such as titanium and nickel based alloys. As the most promising and effective technology for such production and repair the Laser Rapid Prototyping technologies are being used and implemented into the practice. Special focus has been orientated into the Laser Net Shape (LENS) technology. This paper will review the State of the Art of the LENS laser technology and present application case studies where LENS is being applied to manufacture of modern medical implants such as bone fixation plate and jet engine turbine inconel blade
Adsorption and interactions of the bovine serum albumin-double walled carbon nanotube system
Adsorption and interactions of Bovine Serum Albumin (BSA) with Double Walled Carbon Nanotubes (DWNT) prepared by catalytic chemical vapor deposition (CCVD) synthesiswere studied. Adsorption kinetics and equilibrium were investigated by means of in situ UV-spectroscopy. The extent of adsorption at different temperatures was determined at the end of a 420-min adsorption period. The adsorption equilibrium experiments were performed using various amounts of nanotubes at pH 4 and 40 °C, and the adsorption parameters were evaluated comparing the experimental data with models such as the Freundlich and Langmuir isotherms. The maximum protein adsorption capacity (Q0) of DWNTwas determined as 1221 mg·g−1. The effect of temperature on the adsorption rate experimentswas investigated for constant amount of adsorbent at pH 4. Adsorption kinetics followed the pseudo-first-order rate. Zeta potential measurements were performed with respect to solution pH for understanding the protein-surface interactions. The interactions between positively charged BSA molecules with negatively charged DWNT at pH 4 were found to be electrostatic attractions. Thermodynamic parameters, ΔH0 and ΔS0 were found as 9.40 kJ·mol−1 and 321.5 J·mol−1 K−1, respectively. ΔH0 value indicated that BSA adsorption on DWNT was a physisorption process
