As you can see from the title it is aimed at cycling as a part of travel movement in these areas.

O acelerado e freqüente desenvolvimento de novos materiais e técnicas restauradoras tornam necessárias avaliações rápidas que estimem seus desempenhos clínicos. Este estudo avaliou protocolos de envelhecimento acelerado, in vitro, capazes de simular o desempenho de restaurações adesivas frente aos desafios inerentes ao ambiente oral. Foram utilizados 36 molares hígidos, cortados ao meio e divididos aleatoriamente em 12 grupos. Em todos os grupos foi realizada a exposição da superfície dentinária, delimitação da área de adesão e condicionamento ácido da superfície, seguida a aplicação do Sistema Adesivo Scotchbond Multiuso, e colocação da resina composta Z100, em incrementos. Foram confeccionados 6 grupos em formato de palito e 6 grupos em formato de haltere: dois grupos não foram submetidos à ciclagem térmica e mecânica (STSM-P e STSM-H); outros dois foram submetidos à ciclagem térmica (1.000 ciclos; 5-55ºC; 1min em cada banho) e não a mecânica (CTSM-P e CTSM-H); dois ainda foram submetidos à ciclagem mecânica com dispositivo Nova Ética e não a térmica (STNE-P e STNE-H); dois foram submetido à ciclagem mecânica com dispositivo Nova Ética (500.000 ciclos), acrescido de ciclagem térmica (CTNE-P e CTNE-H); outros dois por fim, foram submetidos à ciclagem mecânica por Microrotação (105 ciclos, aproximadamente por 7 horas), e não a térmica (STMR-P e STMR-H); por fim os dois últimos grupos foram submetido à ciclagem mecânica por Microrotação acrescido de ciclagem térmica (CTMR-P e CTMR-H). Todos os grupos foram preparados para teste de microtração. Com as medidas de resistência de união dos palitos e halteres de cada dente foi realizada análise de variância e teste de Tukey. A interação tripla Formato -FORM- (Palito ou haltere) X Ciclagem Térmica- T- (Com e Sem) X Ciclagem Mecânica-M- (Nova Ética e Microrotação) não foi significante (p=0,698), bem como a interação 2 a 2 dos mesmos fatores: FORMxT (p=0,391); TxM (p=0,477); FORM x M (p=0,746). O fator Formato do espécime (Palito ou Haltere) teve diferença extremamente significante (p=0,000), sendo que os valores dos halteres foram maiores que os dos palitos. O fator Ciclagem Térmica (Com e Sem) não foi estatisticamente significante (p=0,2), bem como o fator Ciclagem Mecânica (Nova Ética e Microrotação) (p=0,587). Pode-se concluir que: a ciclagem térmica, bem como as ciclagens mecânicas sistema Nova Ética e Microrotação não foram capazes de reduzir significativamente os valores de resistência de união das interfaces adesivas, nem quando aplicadas isoladamente, nem quando associadas; os espécimes com formato de palito apresentaram valores de resistência de união menores do que os em formato de haltere; não foi possível estabelecer nenhum padrão de degradação entre os grupos através da microscopia eletrônica de varredura; os elementos finitos identificaram uma distribuição mais homogênea das tensões geradas na interface dos espécimes em formato de haltere. / The rapid and frequent development of new materials and restorative techniques necessitate rapid assessments to estimate their clinical outcomes. This study sought to evaluate protocols for accelerated aging, in vitro, capable of simulating the performance of adhesive restorations with challenges inherent to the oral environment. The study included 36 molars that were randomly divided into 12 groups. In all groups were exposed dentin surface, defining the area of adhesion and etching the surface, then the application of Scotchbond Multipurpose Adhesive System, and placement of composite resin Z100, in increments. Six groups were fabricated in the shape of sticks and six other groups in dumbbell shape: the first was not subjected to thermal cycling and mechanical (STSM-P and STSM-H), the second was subjected to thermal cycling (10,000 cycles, 5-55 ° C) and not the mechanics (CTSM-P and CTSM-H); the third was subjected to mechanical cycling device with new Ethics (500,000 cycles) and not thermal (STNE-P and STNE-H); the fourth was subjected to mechanical cycling device with new Ethics, plus thermal cycling (CTNE-P and CTNE-H); the fifth was submitted the mechanical cycling device for Microrotation (105 cycles), but not thermal (STMR-P and STMR-H) and finally the sixth was subjected to mechanical cycling device for Microrotation plus thermal cycling (CTMR-P and CTMR-H). All groups were prepared for microtensile bond-strength test. With the measures of bond strength of each tooth was performed statistical analysis (ANOVA and Tukey test). Random samples of specimens were evaluated by SEM. The triple interaction format (stick or dumbbell-shaped) X Thermal cycling (with and without) X Cycling Mechanics (New Ethics and Microrotation) was not significant (p = 0.698), as well as the interaction 2-2 of the same factors: FORMXT (p = 0.391); TXM (p = 0.477); FORMxM (p = 0.746). With regard to factor Format specimen is observed that the bond strength values obtained for the dumbbell-shaped are higher than those obtained for the sticks (p = 0.000). With regard to factor Thermal cycling was observed that the difference was not statistically significant (p = 0.2). As for factor Cycling Mechanics, the values of groups without cycling were very similar to those obtained in groups cycled through the system New Ethics, and the system by Microrotation, no significant difference between any of them (p = 0.587). The conclusions were that the stick-shaped specimens showed values of bond strength lower than the dumbbell-shaped; thermocycling and mechanical cycling were not able to significantly reduce the values of bond strength of adhesive interfaces, even when applied alone or when associated. It could not be establish any pattern of degradation among the groups by SEM; the finite element identified a more homogeneous distribution of stresses generated at the interface of dumbbell shaped specimens.

This thesis compares the evolution of the policies and programmes for bicycle planning which have developed in Vancouver, B.C., and Seattle, Washington since 1970. The bicycle policies of the two City governments are reviewed, as are the outcomes of these policies in terms of programme activities. The activities of other organisations, both voluntary and governmental, are also considered in the broad review of bicycle-related activities in the two cities. The bicycle policies and programmes of both are compared to models developed from the literature. The reasons for the differing development of bicycle policies and programmes in the two cities are examined from an historical perspective. It is concluded that the development and implementation of a bicycle policy faces similar problems to that of any other policy that is at the margin of political acceptability. It is argued that bicycle policies will be implemented much more readily if there is an active well-organised cyclists' lobby; if there is a bicycle coordinator employed by the municipality; and if cyclists can link their cause to one with broader political support (in this case, open space). / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

In an era that sees sports clubs facing a crisis, a few still grow and attract new members. They use technology for their benefit and provide a place where the members have fun, become aware of their competence, set goals for improvement and experience empowerment. The present qualitative study, conducted with a road cycling club in Germany, investigates how membership is negotiated and confirmed. By exploring the factors that influence the degree of belonging, this research aims to provide some answers on how active members of a cycling hobby club experience becoming part of such a community, what it takes to substantiate membership, and how individual and collective identities are formed and constantly negotiated. The situated learning perspective and Etienne Wenger's Communities of Practice concept have been adopted, and semi-structured interviews with ten participants were conducted. Moreover, observations and conclusions from a stimulated focus group discussion were used. The analysis shows that cycling in a group is a complex, multifaceted learning experience. Power, speed, or cycling skills do not suffice without the will and active efforts to harmonise with a group. Belonging grows parallel to competence, and the degree of competence gets constantly evaluated by the community in their practice, as a combination of contribution to the common goal and ability to be a trusted partner. Competence is thus a “becoming”, reflecting the members’ engagement with the sport and on an interpersonal level.

[pt] Um dos principais desafios em redes de sensores sem fio (RSSF) é reduzir o consumo de energia dos nós sensores. Um método usado para economizar a bateria que alimenta os nós sensores é o duty cycling (DC) do rádio, onde o rádio fica desligado na maior parte do tempo e fica ligado por pouco tempo para verificar se existe alguma mensagem. O DC é usado com frequência em aplicações de monitoramento onde apenas uma mensagem é transmitida depois da leitura do sensor. Geralmente a leitura do sensor só volta a acontecer depois de minutos, logo poucas mensagens são transmitidas por unidade de tempo. Neste trabalho, analisamos o uso da técnica de DC em um contexto diferente, o da disseminação de código, onde várias mensagens são enviadas em um curto espaço de tempo, e que usa mensagens broadcast, ao contrário do monitoramento, que utiliza mensagens unicast. Analisamos dois algoritmos de disseminação específicos, um para um ambiente de máquinas virtuais executando nos motes, onde o código disseminado é um script com tamanho da ordem de bytes, e outro para disseminação de códigos da aplicação inteira, onde o tamanho é bem maior que no caso do script, da ordem de kbytes. O objetivo deste trabalho foi avaliar qual o impacto do DC na latência e quanto de energia foi economizado quando comparado a deixar o rádio ligado o tempo todo, que é como ambos algoritmos funcionam em sua forma original. / [en] One of the key challenges in wireless sensor networks (WSN) is to save energy at motes. One method to save battery is radio duty cycling (DC), which keeps the radio turned off in most of the time and turns the radio on for a short time to verify if any there are any messages. DC is frequently used in monitoring applications where only one message is transmitted after the mote reads its sensor. Usually the mote reads its sensor only once every few minutes, so few unicast messages are transmitted in the network per time unit. This work analyzes the use of the DC method in code dissemination. In this context, multiple broadcast messages are transmitted in a short time. We examined two specific dissemination algorithms, one of them proposed for a virtual machine environment, in which the disseminated code is a small script, and a second one originally proposed for disseminating the code of an entire application, typically much larger than a script. The objective of this study is to evaluate the impact of DC on latency and how much energy was saved when compared to leaving the radio on all the time, which is how both algorithms work in their original form.

The CITY CYCLING (STADTRADELN) campaign has been running since 2008 to motivate German citizens to use the bicycle for daily mobility routines. In the course of the MOVEBIS research project, nationwide GPS data of the CITY CYCLING participants were collected in the years 2018-2020 and were processed for planning purposes. This contribution addresses the question to which extent the participants in the CITY CYCLING campaign represent cyclists in the Federal Republic of Germany and whether the motivation during the campaign leads to a significant change in mobility behaviour. For this purpose, more than 73,000 complete questionnaires of campaign participants from a survey in the year 2020 were evaluated. The age and gender distribution of app users and non-users of the campaign are corresponding to those of cyclists from representative household surveys in Germany (MiD 2017). App users and non app users differ only insignificantly from each other and are, on average, rather older than in the cycling participants of nationwide MiD survey. The results reveal that the smartphone has no significant influence on the cycling behaviour of the users. The survey participants are regular cyclists. Around 88% of the respondents use the bicycle most frequently in everyday life, followed by the private car (national average) and public transport (in large cities). The influence of the campaign on the level of utilisation or the number of kilometres travelled by bike can be described as rather low, overall. Whereas 65% of the participants stated that they cycled to work just as often as outside the campaign period, 19% of the respondents used the bicycle less often for commuting and 16% more often. The results indicate that the CITY CYCLING campaign captures and represents the everyday transport behaviour of participants. During the COVID-19 pandemic, participants used their bicycles significantly more often (73%). The perception of safety is consistently high. The campaign was rated very positively and the majority of users (91%) would participate again or rather recommend the campaign to others (78%).:1. Introduction 2. State of Research 3.

Cycling contributes to public health because it requires physical effort [1] and offers economic and environmental advantages over motorized transport [2]. However, 41,000 cyclists die every year in traffic crashes, 3% of the total worldwide [3]. Most fatal bicycle crashes are collisions with motor vehicles. Severe injuries among cyclists, however, are mostly due to single bicycle crashes and their numbers are increasing [4, 5]. An international review showed that the share of hospitalised casualties due to single-bicycle crashes varied from 3% to 41 % of the total number of hospitalised casualties [ 6]. ... The aim of the present study is to investigate the relationship between cycle track width and lateral position. We conducted an experiment in which the cycle track width was manipulated to determine its effect on lateral position. The results have been compared with previous findings from literature.
