This image was found on creative commons. Some rights are reserved, the image is by Simon Vanherweghe. The original artwork is from Cosmogramma by Flying Lotus, a musician. This piece is of a particular importance to my project as I found the use of field lines very interesting, I am also in awe of this type of illustration and its a great album.

Dirigido a niños de cinco a ocho años, forma parte del plan de estudios del idioma Inglés en el programa nacional de estudios. La colección fue desarrollada en una serie de televisión de la BBC. Consta de veintiseis episodios, cada uno con una historia diferente, dando además, consejos útiles para enseñar a los niños un buen uso del Inglés. Floppy es un perro que tiene un collar con una llave mágica que le permite cumplir sus deseos, en este caso, transportar a los niños Biff, Kipper y Chip en medio de un aeródromo donde cuatro máquinas voladoras están listas para despegar.Una vez que están en el aire, Chip ha de ser capaz de guiarlas hacia abajo en condiciones de seguridad.

Esta serie llena el vacío entre las Etapas uno y dos, está dirigida principalmente a niños que no están haciendo los avances esperados en la lectura y tienen la necesidad de consolidar sus habilidades, antes de que puedan convertirse en lectores con fluidez. Los textos humorísticos motivan a los niños de edades comprendidas entre los siete y los nueve años, mientras que el uso controlado de estructuras de frases les permitirán acceder al texto fácilmente. A Max le gusta jugar al fútbol en la escuela con sus amigos, pero cuando suena la campana uno de los chicos patea el balón demasiado fuerte y Max cree que nunca lo encontrará.

It is well understood that for haptic interaction: free motion performance and closed-loop constrained motion performance have conflicting requirements. The difficulties for both conditions are compounded when increased workspace is required as most solutions result in a reduction of achievable impedance and bandwidth. A method of chaining devices together to increase workspace without adverse effect on performance is described and analysed. The method is then applied to a prototype, colloquially known as 'The Flying Phantom', and shown to provide high-bandwidth, low impedance interaction over the full range of horizontal movement across the front of a human user.

On 8 December 2011, Cyclone Friedhelm, an explosively deepening cyclone, passed across the UK, causing exceptionally strong winds over Scotland and strong winds over much of the UK. A research flight through this intense cyclone was undertaken as part of the DIAMET project. This article gives an account of the flight as experienced by the authors, who were aboard the aircraft. We describe the objectives of the flight and the measurements obtained, and use photographs taken during the flight to illustrate the cloud structures observed.

1. To maximize the probability of rapid contact with a female’s pheromone plume, the trajectories of male foraging flights might be expected to be directed with respect to wind flow and also to be energetically efficient. 2. Flights directed either upwind, downwind, or crosswind have been proposed as optimal strategies for rapid and/or energetically efficient plume contact. Other possible strategies are random and Lévy walks, which have trajectories and turn frequencies that are not dictated by the direction of wind flow. 3. The planar flight paths of males of the day-active moth Virbia lamae were recorded during the customary time of its sexual activity. 4. We found no directional preference in these foraging flights with respect to the direction of contemporaneous wind flow, but, because crosswind encompasses twice the possible orientations of either upwind or downwind, a random orientation is in effect a de facto crosswind strategy. 5. A crosswind preference should be favoured when the plume extends farther downwind than crosswind, and this strategy is realized by V. lamae males by a random orientation of their trajectories with respect to current wind direction

The building industry is often berated for its short comings in meeting up with the demand for the provision of new housing. Addressing the need for new housing stock is a challenge that has led to debates among professional bodies, the construction sector, housing industry and government. The introduction of new manufacturing technologies is often offered as a solution, but the challenges of increasing the amount of off-site construction in residential building are well known and well-rehearsed. The modern flying factory (MFF) is a concept that involves the manufacture of specific components or modules in temporary off- or near- site locations using relatively simple and quick to set up and dismantle technologies and processes. The aim is to produce short batches and hence achieve some of the benefits of off-site manufacture on a much smaller scale than in dedicated factory environments. A case study of a modern flying factory being set up to produce pre-assembled utility cupboards for a large residential development in London is presented, involving participant observation and informal interviews with key actors on the design and operationalising of the process. The case reveals that although there are costs, efficiency and health and safety benefits to using MFF approaches, there are also challenges to overcome over the time required to set up and establish the process for relatively short runs, and in evaluating whether the MFF or traditional site based production is most effective for particular aspects of projects.

Significantly more individuals and biomass of flying insects were present at the forest edge than in the understory throughout the year, as monitored by flight interception traps, in Central Amazonia. Numbers and biomass of flying insects increased at higher rates at the edge with rainfall, associated with termite swarming behavior and increased Homopteran density. The most abundant insects were Diptera, Coleoptera, Hymenoptera and Isoptera, whose ranked abundances varied with respect to forest edge and understory, as well as with season.

In order to evaluate the flying capacity and nest site selection of Angiopolybia pallens (Lepeletier, 1836), we made 17 incursions (136 hours of sample efforts) in Atlantic Rain Forest environments in Bahia state. Our data show this wasp prefers to nest on wide leaves of bushes and short trees (nests between 0.30 and 3m from the ground) placed in half-shady environments (clearings and shadowed cultivations). The logistic regression model using Quasi-Newton method provided a good description of the flying capacity observed in A. pallens (x 2 = 91.52; p≪0.001). According to the logistic regression model, the A. pallens flight autonomy is low, flying for short distances and with an effective radius of action of about 24m measured from their nests, which means a foraging area of nearly 1,800 m 2.

Due to a shortage of textbooks with specific data on muscular activity concerning physical conditioning and sports, we analysed electromyographically the muscles pectoralis major and deltoideus anterior, bilaterally, in inclined flying exercises, during the concentric and eccentric phases, with external loads of 25, 50, 75 and 100% of the maximum load. The electromyographic analysis was performed in eleven male volunteers with MEDITRACE-200 surface electrodes connected to a six-channel biologic signal acquisition module coupled to a PC/AT computer. The electromyographic signals were processed and the obtained effective values were normalized through maximum voluntary isometric contraction. Statistically, the results showed that all the muscles studied presented significant differences between the concentric and the eccentric phases, with higher electromyographic activity during the concentric phase. By analysing the different loads for each muscle in both phases, significant electromyographic activity was observed for all muscles. When the effect of each load on each muscle during the concentric phase was analysed, it was noticed that the muscles on the left were more active than those on the right side, while in the eccentric phase the muscles had different behavior.
