Falling Man: A Literatura em busca de possíveis significados para um espaço vazio

September 11 has originated a wide range of artistic manifestations which have not only searched for plausible explanations for the tragedy, but also tried to review the events. In this sense, this paper aims at showing how a novel reevaluates this episode. The attacks made the United States experience a strong sense of vulnerability, triggering reactions from the American government, whose quick action was translated into a new national security strategy, associated with the war on terror. This paper analyzes the narrative strategies employed by the American author Don DeLillo in his novel Falling Man (2007) in order to reevaluate that tragedy. The debate of the topics is based on texts concerning the relationship between literature and history, postmodern fiction and issues on terrorism. This study contributes to enrich the discussion related to the events that led to the catastrophe and its aftermath, examining characters and groups linked to the September 11 terrorist attacks, revealing multiple truths subjected to social, ideological and historical conditions.

Analise de desgaste em materiais aplicados em discos de freio

Baja SAE competitions challenge engineering students to design and build offroad vehicles, preparing them for the competitive job market. This monograph aims to study a part of the braking of a Baja SAE vehicle system, the brake disc. Giving attention to the wear suffered by discs of two different materials, steel 1045 and stainless steel 304, helping the team Piratas do Vale Bardahl in the best selection between them. Braking tests were performed on a test bench. Both discs have suffered the same braking conditions. Brake pads material, brake line pressure, braking time, number of braking, were parameters which were repeated in the testing of different types of disk, in order to ensure a high power comparison between the obtained data. Before and after the disk tests were weighed and measured, to make a comparison. After the brake tests, the disks were subjected to hardness and surface roughness testing. With the data collected and observations made in the worn parts, the comparison between these two materials was made, obtaining a selection of the best material for the team. The tests showed that steel 1045 has more advantages, compared to stainless steel 304, when applied to brake discs, on the tested conditions

Controle visual da freada em ciclistas: efeitos da incerteza em situação de curva

The purpose of the present study was to analyze the visual control of braking a bicycle when the cyclist is surprised by an obstacle in his way. According to Lee (1976), visually controlled braking based on time to collision information utilizes the optic variables tau and its first derivative in time, tau-dot, to initiating the braking action and regulating its intensity. Seven young adults performed a bicycle braking task in curvilinear trajectory under distinct velocity (high, medium, and low) and uncertainty (certainty and uncertainty) conditions. Results showed that, independently of velocity and uncertainty levels, participants utilized tau and tau-dot to initiating and regulating the braking action, avoiding collision with the obstacle. Cognitive, attentional, and other psychological factors resulting from both increased velocity and uncertainty were not capable of altering the use of time to collision information, corroborating the tested hypothesis

O tipo de trajetória não afeta o controle visual da freada em ciclistas

Braking visual control was studied in recreational cyclists through the manipulation of bicycle’s velocity at braking initiation (low, medium, and high) and approaching trajectory (straight and curved) with respect to a stationary obstacle. The hypothesis was that the type of trajectory, exclusively or interacting with initial velocity, would affect time to collision visual information (tau margin) and its fi rst derivative in time (tau-dot), respectively, in the onset and during braking. The results revealed that velocity affected signifi cantly tau margin while tau-dot remained unaltered independently of condition. The type of trajectory clearly did not affect the visual control of braking in cyclists.
