Dorothy Rungeling fonds, 1887-2013, n.d.

Dorothy Rungeling was born in 1911 and raised in Fenwick, Ontario, by her adopted mother, Ethelwyn Wetherald. After graduating high school, she attended Fort Erie business College. She worked briefly in Toronto and then Hamilton, but eventually took a job with Brown Brothers’ Nursery in Pelham to be closer to home. Dorothy pursued many interests, learning to play the violin, saxophone and clarinet. She met her husband Charles at a local dance where she was playing. In 1939, they opened an automobile and farm machinery business in Welland. In their spare time, they were active in skeet and trap shooting, for which Dorothy won many trophies. In the early 1940s, Dorothy developed a passion for horses, training and showing them in addition to teaching riding at the Welland Riding Club, as well as judging at horse shows. By the late 1940s her interest in horses was waning, but she soon after discovered and pursued a new interest: flying. She joined the Welland Flying Club, obtained a flying licence, and in 1949 purchased her first plane. She proceeded to obtain a Commercial Pilot Licence in 1951, an Instructor’s Licence in 1953, and a Senior Commercial Licence in 1954. She participated in many air races in the 1950s, including the All Women’s International Air Races, the Women’s Transcontinental Air Races, and the Canadian Governor-General’s Cup Air Race. Some of the most notable races were the 1954 International Air Race, where Dorothy met with President Batista of Cuba, and the Governor-General’s Cup Air Race, where she won 1st place in 1953 and 1956 (and was the only woman competing). In 1958, she was also the first Canadian woman to solo pilot a helicopter. That same year she obtained her Airline Transport Licence. She also wrote several articles on aviation, contributing to publications such as Canadian Aviation and Air Facts, a U.S. aviation magazine. In addition to these articles, Dorothy authored several books about her life, as well as a selection of poems and articles by Ethelwyn Wetherald. As planes became more expensive, Dorothy spent less time flying, instead pursuing an interest in sailing. She and her husband bought a sailboat and became members of the Niagara-on-the-Lake Sailing Club. In 2003, Dorothy was awarded the Order of Canada for her accomplishments. She also wrote a regular column for the Voice of Pelham in 2012-2013, called A Century in Pelham. Dorothy celebrated her 100th birthday in 2011, and remains an active member of the community.

Estudio de seguimiento de las audiometrías de los años 2009, 2010 y 2011 de los pilotos de las fuerzas militares

La audición es el segundo mecanismo sensorial más importante después de la visión para obtener información durante la operación de una aeronave. Les permite a los pilotos percibir, procesar identificar los sonidos del ambiente que los rodea. Así necesita oír bien tanto en vuelo como en tierra, especialmente entre 500 y 3000 Hz para la recepción del lenguaje hablado y de las señales auditivas. Objetivo: Determinar los cambios progresivos en el tiempo y las frecuencias auditivas que se afectan en las audiometrías de los pilotos militares de las fuerzas militares en los años 2009, 2010 y 2011. Material y Métodos: Se trata de un estudio longitudinal de cohorte en el cual se identificará el comportamiento de las audiometrías de la población de pilotos de las fuerzas militares de Colombia en los años 2009, 2010 y 2011. Se hará una revisión retrospectiva de dichas audiometrías. Para dicho fin se tomó la población de pilotos de fuerzas militares que fueron distribuidos en grupos de pilotos de aeronave de ala fija que corresponden a 47 pilotos y ala rotatoria que son 155. Conclusiones: Se encontró que la frecuencia mas alterada en la población total fue la de 6000 Hz, que en lo pilotos de ala fija las frecuencias más afectadas fueron las de 4000 Hz y la de 6000Hz, la frecuencia más afectada en los pilotos de ala rotatoria fueron las de 4000 Hz, 6000 Hz y 8000 Hz, con lo que se concluye que la exposición en los pilotos afecta las frecuencias altas en las audiometrías. Se observó una relación con el número de horas de vuelo y las alteraciones audiométricas encontrándose una alteración en los pilotos entre 1000 y 4000 horas de vuelo en las frecuencias de 4000 Hz, 6000 Hz y 8000 Hz y una alteración de las todas las frecuencias en aquellos pilotos con más de 5000 horas de vuelo en el año 2009, presentando posterior recuperación en los años posteriores sin poder determinar en este estudio las causas de dicha recuperación. Los pilotos de ala rotatoria presentaron un incremento sostenido en todas las frecuencias en comparación con los pilotos de ala fija.

Controlo populacional do Elefante Africano : a imunocontracepção

A imunocontracepção tem sido proposta como possível ferramenta para controlar populações de elefantes que ultrapassem as capacidades do habitat onde vivem. Até à data a única técnica imunocontraceptiva testada em elefantes selvagens foi a vacina contra a zona pelúcida de elefantes fêmea utilizando zona pelúcida porcina (pZP) numa vacina que induz a formação de anticorpos anti-zona pelúcida e consequente bloqueio do processo de fertilização. A literatura disponível revela que tal vacina tem uma eficácia contraceptiva que varia entre 22% e 100%, pode ser administrada à distância através de um dardo, é segura para animais gestantes, não passa na cadeia alimentar e é reversível, pelo menos a médio prazo. O estudo realizado no âmbito deste trabalho, teve como objectivo avaliar a técnica utilizada para a vacinação com pZP da população de elefantes femêa na Makalali game reserve (Africa do Sul) em relação ao método, tempo, efeitos secundários, e custos envolvidos. Todos os animais foram vacinados apartir de um helicóptero, o processo teve uma duração média por elefante de 2.8 minutos, observou-se efeitos secundários locais em 4 individuos, duas das três manadas evidenciaram alterações comportamentais após a vacinação, e o custo total da operação foi de 3417 dólares americanos.

Patch Scale Nest-Site Selection by Marbled Murrelets (Brachyramphus marmoratus)

The Marbled Murrelet (Brachyramphus marmoratus) is a threatened alcid that nests almost exclusively in old-growth forests along the Pacific coast of North America. Nesting habitat has significant economic importance. Murrelet nests are extremely difficult and costly to find, which adds uncertainty to management and conservation planning. Models based on air photo interpretation of forest cover maps or assessments by low-level helicopter flights are currently used to rank presumed Marbled Murrelet nesting habitat quality in British Columbia. These rankings are assumed to correlate with nest usage and murrelet breeding productivity. Our goal was to find the models that best predict Marbled Murrelet nesting habitat in the ground-accessible portion of the two regions studied. We generated Resource Selection Functions (RSF) using logistic regression models of ground-based forest stand variables gathered at plots around 64 nests, located using radio-telemetry, versus 82 random habitat plots. The RSF scores are proportional to the probability of nests occurring in a forest patch. The best models differed somewhat between the two regions, but include both ground variables at the patch scale (0.2-2.0 ha), such as platform tree density, height and trunk diameter of canopy trees and canopy complexity, and landscape scale variables such as elevation, aspect, and slope. Collecting ground-based habitat selection data would not be cost-effective for widespread use in forestry management; air photo interpretation and low-level aerial surveys are much more efficient methods for ranking habitat suitability on a landscape scale. This study provides one method for ground-truthing the remote methods, an essential step made possible using the numerical RSF scores generated herein.

John Lewis Partnership lessons in logical incrementalism and organic growth: a case study and interview with the Chairman, Mr Charlie Mayfield

Purpose – The purpose of this paper is to demonstrate how strategy is developed and implemented in an organisation with an unusual ownership model. Partnerships are not a prevalent form of ownership but as this case demonstrates they can be extremely effective. Furthermore this case demonstrates how logical incrementalism can be used to implement major strategic decisions. Design/methodology/approach – The paper draws on company documentary evidence and a semi-structured interview with Mr Charlie Mayfield, Chairman of John Lewis Partnership. A chairman has a helicopter view of business whose perspectives are rarely captured by strategy researchers. This case study offers an insight into strategic thinking of a chairman and chief executive of a successful company. Research limitations/implications – The case study and interview offer a unique insight into the rationale behind strategic decisions within a successful partnership that has grown organically in a highly competitive retail market without high gearing. Originality/value – This case study sheds light on strategic moves within partnership. Furthermore, very few case studies offer insight into the thinking of a chief executive who has successfully managed a business in a turbulent environment.

Avaliação da gravidade do trauma em condutores de motocicleta vítimas de acidentes de trânsito no Rio Grande do Norte

Descriptive exploratory study, prospective, with quantitative approach, performed on the Monsenhor Walfredo Gurgel Hospital Complex (MWGHC), in Natal/RN, aiming to identify injuries by body area and wound severity on drivers who suffered motorcycle accidents, evaluate the severity of injuries and trauma on these drivers and identify the existence of association between wound and trauma severity and some of the accident s characteristics. The population comprised 371 motorcycle drivers, with data collected between October and December 2007. We used as instruments the Abberviated Injury Scale (AIS), Injury Severity Score (ISS) and the Glasgow Coma Scale (GCE1). The results show that, concerning characterization, there was a predominance of the male gender (88.4%), aged between 18 and 24 years (39.90%), originating from the Natal metropolitan region (55.79%), with fundamental-level instruction (51.48%), catholic (75.78%), married (47.98%). 23.18% work on commerce-related activities and 75.20% have income of up to 2 minimum wages. As for the accident s characteristics, the predominant shift was the afternoon (46.36%), received up to one hour after the event (50.67%), transported by countryside ambulances colleagues and relatives (51.21%), 25.34% had the accident on Sunday; 53.91% suffered falls and vehicle rolls; among the collisions there was a predominance of the motorcycle-automoblie type (28.03%); 52,6% were licensed and among these 50.76% had up to one year of license; 65.50% declared not having suffered previous accidents; 65.77% declared waring helmets in the time of the accident; 57.41% said not to have used drugs, and among those who used, alcohol was the most consumed (98.10%). The lowest score evaluated by GCS1 (3 to 8) was linked to drivers who suffered accidents on Saturday (10.3%), those who were not wearing helmets (14.29%) and the victims of motorcycle-pedestrian/animal crashes (13.33%). The body areas most affected had AIS between 1 and 3 (95.76%) and were: external surface (39.90%) and head/neck (33.20%). As for trauma severity, the highest scores (ISS>25) belonged to those who consumed alcohol (30.73%), suffered falls or vehicle rolls (48.9%) and those attended to 3 hours or longer after the accident (50%). We conclude that for motorcycle drivers who suffered accidents, age, gender, weekday, type of accident, use of drugs and the absence of helmet use signal both to the risk of occurrence of these events, as well as for the greater severity of injuries and trauma.

A technique for the capture of free-ranging marsh deer (blastocerus dichotomus)

The marsh deer (Blastocerus dichotomus) is an endangered species froth the marshlands of central South America. Its population has declined in several regions due to the loss of available habitat caused by human activities, especially the construction of hydroelectric darns. The capture of individual deer is critical for research programs and population management. This report describes a novel live-capture technique, which uses a helicopter to drive the animals into a terrain that restricts their movement such as thick vegetation or deep water (60-120 cm in depth). Following confinement, animals are manually restrained. The short pursuit time (median = 2 thin), low mortality rate (0.82-3.28%), and the absence of injury to both the capture team and animals suggest that this method is appropriate for the safe capture of this species. Body temperature correlated with the pursuit time (R-2 = 0.15) but was not significantly altered with pursuit times <3 min.

Sistema de supervisão aérea baseado em navegação visual para detecção de anomalias em instalações de petróleo e gás

This work deals with the development of a prototype of a helicopter quadrotor for monitoring applications in oil facilities. Anomaly detection problems can be resolved through monitoringmissions performed by a suitably instrumented quadrotor, i.e. infrared thermosensors should be embedded. The proposed monitoring system aims to reduce accidents as well as to make possible the use of non-destructive techniques for detection and location of leaks caused by corrosion. To this end, the implementation of a prototype, its stabilization and a navigation strategy have been proposed. The control strategy is based on dividing the problem into two control hierarchical levels: the lower level stabilizes the angles and the altitude of the vehicle at the desired values, while the higher one provide appropriate references signals to the lower level in order the quadrotor performs the desired movements. The navigation strategy for helicopter quadrotor is made using information provided by a acquisition image system (monocular camera) embedded onto the helicopter. Considering that the low-level control has been solved, the proposed vision-based navigation technique treats the problem as high level control strategies, such as, relative position control, trajectory generation and trajectory tracking. For the position control we use a control technique for visual servoing based on image features. The trajectory generation is done in a offline step, which is a visual trajectory composed of a sequence of images. For the trajectory tracking problem is proposed a control strategy by continuous servovision, thus enabling a navigation strategy without metric maps. Simulation and experimental results are presented to validate the proposal

Simulação numérica da interação entre uma nuvem incidente de vórtices e uma aerofólio através do método dos vórtices

The study of aerodynamic loading variations has many engineering applications, including helicopter rotor blades, wind turbines and turbo machinery. This work uses a Vortex Method to make a lagrangian description of the a twodimensional airfoil/ incident wake vortex interaction. The flow is incompressible, newtonian, homogeneus and the Reynolds Number is 5x105 .The airfoil is a NACA 0018 placed a angle of attack of the 0° and 5°simulates with the Painel Method with a constant density vorticity panels and a generation poit is near the painel. The protector layer is created does not permit vortex inside the body. The vortex Lamb convection is realized with the Euler Method (first order) and Adans-Bashforth (second order). The Random Walk Method is used to simulate the diffusion. The circular wake has 366 vortex all over positive or negative vorticity located at different heights with respect to the airfoil chord. The Lift was calculated based in the algorithm created by Ricci (2002). This simulation uses a ready algorithm vatidated with single body does not have a incident wake. The results are compared with a experimental work The comparasion concludes that the experimental results has a good agrement with this papper

Construção de mosaicos georreferenciados usando imagens aéreas de pequeno formato

In this work we propose a technique that uses uncontrolled small format aerial images, or SFAI, and stereohotogrammetry techniques to construct georeferenced mosaics. Images are obtained using a simple digital camera coupled with a radio controlled (RC) helicopter. Techniques for removing common distortions are applied and the relative orientation of the models are recovered using projective geometry. Ground truth points are used to get absolute orientation, plus a definition of scale and a coordinate system which relates image measures to the ground. The mosaic is read into a GIS system, providing useful information to different types of users, such as researchers, governmental agencies, employees, fishermen and tourism enterprises. Results are reported, illustrating the applicability of the system. The main contribution is the generation of georeferenced mosaics using SFAIs, which have not yet broadly explored in cartography projects. The proposed architecture presents a viable and much less expensive solution, when compared to systems using controlled pictures

Large segmental radius and ulna defect treated by bone transportation with the Ilizarov technique

An 8-year-old male Boxer with a severely contaminated open fracture of the left radius and ulna fracture, produced by a helicopter propeller, was treated using bone transport by the Ilizarov method. Extensive diaphyseal bone loss and soft-tissue vascular damage were present. The radius and ulna were stabilised with an Ilizarov ring external fixator. The bone defect was partially shortened and restored by gradual transport of a bone segment created from proximal segments of the radius and ulna. The external fixator was removed 4fi months after the beginning of the latency period, due to instability caused by osteolysis around the wires. A cast was placed for 3 weeks. Although the bone transport had resulted in formation of approximately 4 cm of bone, the antebrachium showed approximately 50% shortening when compared to the contralateral limb. The infection was eradicated, and the dog was able to bear weight on the operated limb when walking.
