This article and research is based on recent patents filed with the USPTO (US Patent Serial No. 13/969,529 and 14/450,425), and Professional experiences in the built environment for over thirty years. The intention of this invention is focused on absorbing and / or redirecting forces two dimensionally or three dimensionally in any mechanism that relies on moving and / or force resolving components (structural manipulation of forces) so more benefits of the mechanism can be achieved under a longer duration.

Editorial Summary With a focus on experiential qualities Maria da Piedade Ferreira distinguishes her research object from classical (rather technical) quantities such as load-bearing capacities. In her text she illustrates how she employs methods, techniques, and instruments from performance art and neurosciences to investigate the effects of spatial conditions on the human body. In doing so, she explores a mix of qualitative and quantitative approaches, namely by experimenting with emotion measurement: Qualitative research, by including methodologies which attribute measurable values to the felt experience, might help us better understand the effects of the built environment in the human body during the design process itself, and after building. Accordingly, her aim is to integrate art and science methodologies that allow us to design spaces as intelligent extensions of the human body and positively impact how this feels and acts in the world.

This article is based on an invention focused on absorbing and redirecting forces two dimensionally or three dimensionally in any mechanism that relies on force resolving members, so more benefits of the mechanism can be achieved. This Assembly is focused on new ideas for framing and connections to resolve forces so the rigidity between members can be minimized and the Assembly can sustain performance under longer durations and more unique loadings, i.e., seismic loading on structure. The Assembly uses several techniques and fundamentals for efficient force dissipation with, or without deflection while creating a controlled rotation when loaded. The allowable arrangement of the Assembly within itself (web members within outer and inner rings and arcs), and as an assortment of assemblies, can be limitless. This arrangement, configuration of web members, numbering, width and flexibility, can be arranged for a predictable and controlled deflection or rotation in any direction, due to loading from any direction and type, thus creating a load bearing and load dissipating Assembly with greater efficiency, and advance the life of interacting parts under loadings, i.e., seismic loading of structures. This Assembly, in particular the web members, can be an arrangement and properties of arcs to offer a desired response, as well as create a rotation when loaded.

SummaryTotal removal of a knee joint meniscus is followed by osteoarthritis in many mammalian species. Altered load-bearing has been observed in the human knee following meniscectomy but less is known about biochemical effects of meniscectomy in other species. Using pressure sensitive paper in sheep knee (stifle) joints it was found that, for comparable loads, the load-bearing area on the medial tibial condyle was significantly reduced following medial meniscectomy. Also, for loads of between 50 N and 500 N applied to the whole joint, the slope of the regression of contact area against load was much smaller. Following medial meniscectomy, the ability to increase contact area as load increased was markedly reduced.The load bearing area on the medial tibial condyle was reduced following meniscectomy.
