A process configuration combining thermal hydrolysis (TH) and anaerobic digestion (AD) of sludge has been studied with the objective of analysing the feasibility of the technology for full scale installations. The study has been performed through pilot scale experiments and energy integration considerations, and a scheme of the *Corresponding author most profitable option is presented: thermal hydrolysis unit fed with 7% total solids (TS) secondary sludge, anaerobic digestion of the hydrolysed sludge together with fresh primary sludge, and a cogeneration unit to produce green electricity and provide hot steam for the thermal hydrolysis process.

ResumenEn este artículo presentamos una propuesta conceptual, la de "Feminismos periféricos", que pretende englobar algunos de los planteamientos realizados en el marco de lo que se denomina feminismos de la tercera ola, feminismos post-coloniales o feminismos del tercer mundo. Se trata de un instrumento de análisis concebido para comprender mejor cómo se relacionan -o se pueden relacionar-las categorías de sexo, clase y raza (y etnicidad) en diferentes campos de análisis, momentos históricos y distintas disciplinas. Las protagonistas que dan sentido a esta propuesta son las mujeres que pueblan la periferia social: mujeres pobres, discapacitadas, con otra orientación sexual y, especialmente, las denominadas inmigrantes.
Palabras clavesFeminismos periféricos, tercera ola de feminismos, feminismos del tercer mundo, teoría postcolonial.
The purpose of this paper is to assess the radiological features of the unilateral angular deformity of the distal end of the femur secondary to a focal fibrous tether. Only five cases of this entity have been reported in the literature. We report another two patients. Magnetic resonance study was performed on one of them, which has not been used in previous cases. Both cases are described with illustrations of the typical radiographic appearances supplemented by CT and MR imaging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
