Can Mixed Martial Arts be Ethically Defended?: Autonomy, Paternalism and the Harm Principle
Abstract Mixed Martial Arts (MMA) and the Ultimate Fighting Championship (UFC) founded in 1993 have been under scrutiny for the past two decades. Unlike boxing, the ethical status of MMA and whether it is morally defensible have rarely been analyzed in the academic literature. I argue that MMA …

Efeito da amônia sobre as convulsões e a inibição da sucinato desidrogenase induzidas por ácido metilmalônico
… e acúmulo tecidual de ácido metilmalônico (MMA). Embora existam evidências de que o MMA induza convulsões por inibição da sucinato desidrogenase (SDH), muito pouco se sabe sobre a contribuição da hiperamonemia para o desenvolvimento das convulsões nestes pacientes. No presente estudo …

Robust and flexible multi-scale medial axis computation
The principle of the multi-scale medial axis (MMA) is important in that any object is detected at a blurring scale proportional to the size of the object. Thus it provides a sound balance between noise removal and preserving detail. The robustness of the MMA has been reflected in many existing …

Estuaries as Sources of Methylated Arsenic to the North Sea
… arsenic (As(III) and As(V)), monomethylarsenic (MMA) and dimethylarsenic (DMA) in water, pore waters, suspended particles and bed sediments of the Humber Estuary, Thames Estuary and the southern North Sea. Dissolved inorganic As in the Humber Estuary showed removal in the mouth of the estuary in …

Nutritional status and weight making practices of professional male South African mixed martial arts fighters
… sport athletes, including mixed martial arts (MMA) fighters, often 'make weight' or 'cut weight' to fight in lower weight divisions. Common weight-making practices include restriction of food and/or fluid intake and intentional fluid loss/sweating (e.g. sauna). However, a number of these …

Materials and coatings derived from the polymerizable ionic liquid surfactant 1-(2-Acryloyloxyundecyl)-3-methylimidazolium bromide
… The ternary phase diagram of the ILBr/ MMA/water system was constructed at 25 and 60 °C. Several microemulsion polymerizations were carried out, yielding materials that ranged from latexes, which formed transparent films upon drying, to solid rods. These materials were analyzed by …

Criteria for evaluating model deficiency for groundwater models and the effects of eliminating deficient models on multi-model analysis using AICC, KIC, AIC, and BIC
Multi-model analysis (MMA) considers multiple model interpretations of a system. MMA provides a more realistic assessment of uncertainty associated with model predictions because both uncertainty of individual models and uncertainty associated with different model structures are considered. Models …
