In mid-July 2003, the U.S. Army Tank-Automotive & Armaments Command (TACOM) performed a series of experiments at Keweenaw Research Center (KRC), with a remote operated mine roller system. This system, named Panther Lite, consists of two M113 Armored Personnel Carriers (APC’s) connected by a Tandem Vehicle Linkage Assembly (TVLA). The system has three sets of mine rollers, two of which are connected to the front of the lead vehicle with one set trailing from the trail vehicle. Currently, the system requires two joystick controllers. One regulates the braking of the tracks, throttle, and transmission of the lead vehicle and the other controls the braking and throttle of the rear vehicle. One operator controls both joysticks, attempting to maneuver the lead vehicle along a desired path. At the same time, this operator makes compensation maneuvers to reduce lateral loads in the TVLA and to guide the rear mine rollers along the desired path. The purpose of this project is to create algorithms that would allow the slave (trail) vehicle to operate using inputs that maneuver the control (lead) vehicle. The project will be completed by first reconstructing the experimental data. Kinematic models will be generated and simulations created. The models will then be correlated with the reconstructions of the experimental data. The successful completion of this project will be a first step to eliminating the need for the second joystick.

Este trabalho de investigação aplicada é o reflexo de um estudo comparativo entre duas forças mecanizadas, nomeadamente o Batalhão de Infantaria Mecanizado português e o Regimento de Infantaria Mecanizado francês. Este estudo incide sobre quatro vetores de desenvolvimento, nomeadamente, a doutrina ao nível da tipologia das forças em estudo, da organização, ou seja, dos seus quadros orgânicos, ao material, mais propriamente os principais sistemas de armas empregues pelas duas forças, assim como às infraestruturas disponíveis para treino. O presente trabalho trata de um estudo comparativo, tendo como natureza a investigação aplicada. Este estudo comparativo tem como principal objetivo confrontar a doutrina com a prática, bem como identificar e caracterizar as principais vulnerabilidades e potencialidades das duas forças em estudo, tendo em conta os vetores de desenvolvimento anteriormente apresentados, podendo assim, rentabilizar os meios em uso no Batalhão de Infantaria Mecanizado e/ou contribuir para uma futura aquisição. Verificámos que a principal diferença entre as duas forças em estudo assenta na sua tipologia, isto é, enquanto que a força francesa é considerada pesada, a força portuguesa é média, embora pretenda e esteja no caminho de vir a ser uma força pesada. O que nos leva à grande diferença, derivada da tipologia de forças, que são as viaturas empregues pelas duas forças, ou seja, uma viatura blindada de transporte de pessoal e uma viatura de combate de infantaria. Para se assumir como força pesada, o Batalhão de Infantaria Mecanizado português, precisa de adquirir uma viatura de combate de infantaria, para assim, dar o “salto” qualitativo, numa perspetiva de armas combinadas. Palavras-Chave: Mecanizado, Vetores de Desenvolvimento, Viatura Blindada Transporte Pessoal, Viatura Combate de Infantaria.

A total of 70 Staphylococcus aureus isolates from postoperative infections in hospitalized horses were isolated between January 2005 and January 2011. Among them, 12 isolates were methicillin-susceptible S. aureus (MSSA), 18 were borderline-oxacillin-resistant S. aureus (BORSA), and 40 were methicillin-resistant S. aureus (MRSA). During the same period, the equine clinic personnel were screened for nasal carriage of BORSA and MRSA. Genotyping revealed that BORSA ST1(MLST)-t2863(spa) isolates were responsible for most equine infections and were the main isolates found in colonized members of the personnel between 2005 and 2007, and that in 2007, MRSA ST398-t011-IVa(SCCmec) emerged in infection sites and personnel, replacing BORSA. Besides decreased susceptibility to oxacillin, all MRSA and BORSA of these two major clonal lineages displayed resistance to gentamicin and kanamycin conferred by the aac(6')-Ie-aph(2')-Ia gene and to trimethoprim conferred by dfr(K) in MRSA and dfr(A) in BORSA. All MRSA had additional resistance to tetracycline conferred by tet(M), whereas BORSA generally also display resistance to streptomycin conferred by str. The number of hospital-acquired MRSA infections in horses could be limited after the introduction of basic hygiene measures and personnel decolonization. Two MRSA carriers could not be decolonized using mupirocin, and a year after decolonization, additional members were recolonized with MRSA. Hygiene measures should, therefore, be maintained to limit the transmission of S. aureus between personnel and horses.
