O conceito científico de Lideranca situaçional explica que um líder tem que ser uma pessoa de múltiplas Funções e Competências. Nas empresas alemaes tem muitos pessoas pensando ser líderes, mas no fundo eles são somente Administradores. a diferenca é o seguinte: alguem que é somente capaz de trabalhar com seu conhecimento e com seus ferramentas, já sabe muito, mas isso nao è suficiente para ter sucesso. Ele è de verdade somente um administrador. Pois para ser um Líder de verdade ele precisa além disso as competencias social e individual.
Pensando na motivação de uma perspectiva gerencial, é muito importante ter a seguinte visão: ninguem pode conseguir motivar outras pessoas, mas um lider pode influenciá-las a fazer as coisas com mais entusiasmo. Além disso, ele deve conhecer a sua personalidade mesmo. Ele precisa de reconhecimento dos pontos fortes e fracos proprios. Quem – por exemplo – é bem fechado, precisa desenvolver mais forca para motivar as outras pessoas. Quem – por outro exemplo – adora de fazer todas coisas sozinho, vai ter dificuldades com delegação para seus funcionarios. Se ele sabe desse ponto fraco proprio, ele pode evitar esse ponto fraco e delegar de verdade. Para conseguir essa meta, um dialogo de ´feedback´ com os funcionarios e muito importante para descobrir as diferenças entre a auto-percepção e o percepção dos outros, por exemplo sobre o estilo de liderança aplicada.
A 2nd generation high performance small animal PET scanner, called ClearPET™, has been designed and a first prototype is built by working groups of the Crystal Clear Collaboration (CCC). In order to achieve high sensitivity and maintain good uniform spatial resolution over the field of view in high resolution PET systems, it is necessary to extract the depth of interaction (DOI) information and correct for spatial degradation. The design of the first ClearPET™ Demonstrator based on the use of the multi-anode photomultiplier tube (Hamamatsu R7600-M64) and a LSO/LuYAP phoswich matrix. The two crystal layers of 8*8 crystals (2*2*10 mm3) are stacked on each other and mounted without light guide as one to one on the PMT. A unit of four PMTs arranged in-line represents one of 20 sectors of the ring design. The opening diameter of the crystal ring is 137 mm, the axial detector length is 110 mm. The PMT pulses are digitized by free-running ADCs and digital data processing determines the gamma energy, the phoswich layer and even the pulse arrival time. Single gamma interactions are recorded and coincidences are found by software. The gantry allows rotation of the detector modules around the field of view. The measurements have been done using the first LSO/LuYAP detector cassettes.
The ClearPET™ project is proposed by working groups of the Crystal Clear Collaboration (CCC) to develop a 2nd generation high performance small animal positron emission tomograph (PET). High sensitivity and high spatial resolution is foreseen for the ClearPET™ camera by using a phoswich arrangement combining mixed lutetium yttrium aluminum perovskite (LuYAP:Ce) and lutetium oxyorthosilicate (LSO) scintillating crystals. Design optimizations for the first photomultiplier tube (PMT) based ClearPET camera are done with a Monte-Carlo simulation package implemented on GEANT3 (CERN, Geneva, Switzerland). A dual-head prototype has been built to test the frontend electronics and was used to validate the implementation of the GEANT3 simulation tool. Multiple simulations were performed following the experimental protocols to measure the intrinsic resolution and the sensitivity profile in axial and radial direction. Including a mean energy resolution of about 27.0% the simulated intrinsic resolution is about (1.41±0.11)mm compared to the measured of (1.48±0.06)mm. The simulated sensitivity profiles show a mean square deviation of 12.6% in axial direction and 3.6% in radial direction. Satisfactorily these results are representative for all designs and confirm the scanner geometry.
For the application of the concept of Lightning Protection Zones (LPZ), the knowledge of the magnetic fields and induced voltages inside a structure is necessary. Laboratory experiments have been conducted at a downscaled model of a building (scale factor 1:6) to determine these electromagnetic quantities in case of a direct strike to the structure. The model (3 m x 2 m x 2 m) represented a small industrial building using the reinforcement of the concrete as electromagnetic shield. The magnetic fields and magnetic field derivatives were measured at several location inside the scaled model. Further, the voltages induced on three typical cable routes inside the model was determined. The influence of the lightning current waveshape, point-of-strike, bonding of the cable routes, and bridging of an expansion joint in the middle of the building on these quantities was studied.
