Comparison between common traffic lights and three types of traffic lights with visual cycle a safety and capacity analysis

The objective of this paper is compare the common traffic lights (CTL) to three different types of traffic lights with countdown displays (SCD) and assess their effects on road safety and capacity. This comparison is required because the results found in the literature are divergent among countries and cities, and one of the SCD analyzed in our study is different from the SCD used worldwide. An observational before-after study was conducted to evaluate the safety and capacity in a period of one year before and one year after the implementation of the SCD in three Brazilian cities. The results indicate that the SCD models 1 and 3 had around 35%±14% reduction in the total number of accidents; the model 2, does not have significant reduction. In order to perform the capacity analysis a framework for data collection and an adaptation for estimation of initial lost time in each phase were developed. Considering the capacity analysis there was a reduction around 11% in the lost time in SCD model 1, 7% in SCD model 2 and 3% in SCD model 3. However the implications of this on capacity are trifle due to a small increase in the average headways for all SCD models compare to CTL.

NIGHT FLIGHT ACROSS A BLUE SKY: PROGNOSTICS

The purpose of this presentation is to gain new perspectives on pest control and related phenomena. Some will call it “blue sky.” I would claim it informal futuristics. Systems men call such efforts feedforward; others grandify it with “prognostics.” Some say prognostics is one of the leading challenges of the day. We must anticipate future developments and imagine or invent new alternatives as a background for rational choice. The activity can influence today’s decisions, modify our concepts of risks and probable payoffs, and can help those of us who ask: “What am I really doing; what should I be doing?”

Weight gain in relation to night work among nurses

Objective: To investigate the relationship between working at night and increased body weight in nursing. In addition, we evaluated the differences in the proportion of variables sociodemographic, work and health, according to the work shift and their association with body mass index. Methods: Based on questionnaires, we obtained data from 446 nursing professionals about aspects of their job, health and lifestyle. We performed linear and logistic regression analysis. Results: Working at night is associated with a weight gain greater than (beta=0.24 kg/m(2)) working during the day (beta=0.15 kg/m(2)), as well as with aging (beta=0.16 kg/m(2)) and duration of working in nursing (beta=0.18 kg/m(2)). Night workers have a higher educational level, have been working for more years in nursing and also in the current shift, do not have diabetes and have reported longer sleep than day workers. There are also a higher number of smokers among the night workers than day workers. Logistic regression analysis also showed the more time to work in nursing and as an assistant was more likely to develop overweight/obesity. Conclusion: Working at the night contributes to more weight gain than the day shift, aging and duration of working in nursing.

Daily rhythm of salivary IL-1 beta, cortisol and melatonin in day and night workers

Shiftwork-induced sleep deprivation and circadian disruption probably leads to an increase in the production of cytokines and dysregulation of innate immune system, respectively. This project aims evaluating changes in salivary IL-1 beta, cortisol, and melatonin in night workers. Method. Two day and three night healthy workers participated in this study. Sleep was evaluated by actimetry and activity protocols. Saliva was collected at waking and bedtime the last workday and the following two days-off and was analyzed by ELISA. Results. Neither sleep duration nor efficiency showed any association with salivary IL-1beta. IL-1beta levels were higher at waking than at bedtime during working days for all workers, but only one day and one night-worker maintained this pattern and hormone rhythms during days off. For this night worker, melatonin levels were shifted to daytime. A second one presented clear alterations in IL-1beta and hormone rhythms on days-off. Conclusions. Our preliminary results suggest that night work can disturb the variation pattern of salivary IL-1beta. No association of this variation with sleep was observed. It seems that disruption in hormone rhythms interfere with salivary IL-1beta production. IL-1beta production pattern seems to be maintained when rhythms are present, in spite of a shift in melatonin secretion.

La nuit dans les romans des Lumières Du roman libertin au roman gothique

Cette thèse se propose d’analyser les images de la nuit et ses significations dans les romans du XVIII siècle, à partir des années 1730-1740, dans le cadre de trois littératures: la littérature anglaise, française et italienne. Deux conceptions opposées sont mises en comparaison: la première, d’exorcisation de la nuit, est typique de la première partie du siècle; elle est représentée principalement par le genre des romans libertins. La deuxième conception montre une valorisation de la nuit qu’on trouve en particulier dans les romans gothiques, qui se sont développés à partir de la seconde partie du siècle. Le but final de la présente recherche est de trouver une explication au refus de la nuit de la part de certains auteurs et ensuite de repérer les causes du bouleversement de cette vision. Puisque la nuit empêche le sens de la vue, elle a été considérée une forme de négation de l’espace physique; selon le profil psychologique et anthropologique la nuit constituerait alors la cause principale de la perte d’orientation. Selon une interprétation intellectuelle et philosophique, elle serait un symbole d’ignorance et d’irrationalité. La situation change vers la moitié du siècle des Lumières, car la nuit commence à assumer un rôle actif et nécessaire dans le processus d’apprentissage. Au niveau social, les rencontres les plus importantes adviennent pendant la nuit. Dans le revival des cathédrales gothiques et des châteaux médiévaux, on voit que la nuit s’empare désormais de l’espace, qui s’enrichit de lumières et d’ombres.

Drammatizzazioni devozionali del Venerdì santo a Milano in età post-tridentina: la processione con Misteri dei Barnabiti

La tesi si occupa della «processione con Misteri» organizzata da Carlo Bascapè, preposito generale dei Barnabiti, a Milano, la notte del venerdì santo, a partire dal 1587. Di questo importante rito processionale sono giunte fino a noi diverse testimonianze documentarie, conservate presso l’Archivio Storico dei Barnabiti a Milano, che sono state il cuore di questa ricerca. La processione è una grande meditazione pubblica dove la musica svolge un ruolo molto importante. Il percorso che ho seguito è stato teso a rendere ragione delle motivazioni drammatiche e devozionali della processione, per poi approdare al significativo ruolo che la componente musicale svolgeva nel rito stesso. Nel primo capitolo ho rievocato la figura di Carlo Bascapè (1550-1615), inserendo la sua figura all’interno delle esperienze storiche nelle quali si è formato (la Milano di san Carlo Borromeo e l’Ordine dei Chierici regolari di San Paolo). Nel secondo capitolo ho scandagliato le radici devozionali alla base della processione (i concetti di devozione e orazione) e messo a fuoco il ruolo della musica nell’esperienza religiosa dei Barnabiti e, in particolar modo, di Carlo Bascapè. Il terzo capitolo si concentra sulle principali modalità di rappresentazione e meditazione della passione di Cristo. Nel quarto capitolo ho ricostruito, attraverso una lettura dei documenti, e con approfondimenti tratti dalla letteratura devozionale tardocinquecentesca sulla passione, i vari aspetti della processione e i suoi protagonisti (religiosi, nobili della città di Milano, musicisti), e, infine, ho messo in luce gli aspetti devozionali e drammaturgici. Nel quinto capitolo ho analizzato le musiche superstiti, pervenendo alla conclusione che ogni aspetto musicale era concepito tenendo ben presenti i due aspetti su cui era imperniata la processione: la rappresentazione della passione e l’immedesimazione dei fedeli. L’ultima parte della tesi consiste, infine, nella trascrizione dei documenti archivistici, nella loro parte testuale e musicale.

Night Vision Imaging System (NVIS) certification requirements analysis of an Airbus Helicopters H135

The safe operation of nighttime flight missions would be enhanced using Night Vision Imaging Systems (NVIS) equipment. This has been clear to the military since 1970s and to the civil helicopters since 1990s. In these last months, even Italian Emergency Medical Service (EMS) operators require Night Vision Goggles (NVG) devices that therefore amplify the ambient light. In order to fly with this technology, helicopters have to be NVIS-approved. The author have supported a company, to quantify the potentiality of undertaking the certification activity, through a feasibility study. Even before, NVG description and working principles have been done, then specifications analysis about the processes to make a helicopter NVIS-approved has been addressed. The noteworthy difference between military specifications and the civilian ones highlights non-irrevelant lacks in the latter. The activity of NVIS certification could be a good investment because the following targets have been achieved: Reductions of the certification cost, of the operating time and of the number of non-compliance.

Day/Night rhythm of hemostatic factors in obstructive sleep apnea

To investigate the hypothesis that day/night patterns of prothrombotic activity differ between patients with obstructive sleep apnea (OSA) and individuals with no OSA.

Implementing The Good Friday Agreement: Overcoming Challenges and Obstacles

On April 10, 1998, history was made in Northern Ireland. Years of sectarian violence would end as the Belfast Agreement, known more popularly (and perhaps more fittingly due to the religious identities defining the two sides) as the Good Friday Agreement, was signed bringing peace to Northern Ireland (Northern Ireland Office, 2007). This paper will look at the Good Friday Agreement in detail. By analyzing the historical factors leading up to 1998, the Agreement itself, and the post-Agreement implementation stage,it is possible to pick out the relative successes and failures of the Agreement, and of its implementation.

Effect of continuous positive airway pressure on day/night rhythm of prothrombotic markers in obstructive sleep apnea

Obstructive sleep apnea (OSA) has been associated with an increased risk of atherothrombotic events. A prothrombotic state might partially explain this link. This study investigated OSA patients' day/night rhythm of several prothrombotic markers and their potential changes with therapeutic continuous positive airway pressure (CPAP).
