This paper presents findings of a study on optimization and application of the regenerated bone char media for the defluoridation of drinking water in Tanzania where more than 30% of all water sources have fluoride concentrations above the 1.50 mg/I which is recommended by the World Heath Organization (WHO). In this study, regeneration temperature, regeneration duration, contact time, regenerat...

A large incomplete ostrich femur from the Lower Pleistocene of North China, kept at Muséum National d’Histoire Naturelle (Paris), is described. It was found by Father Emile Licent in 1925 Nihewan Formation (dated about 1.8 Ma) Hebei Province. On basis minimum circumference shaft, a mass 300 kg, twice that modern ostrich, obtained. The bone remarkably robust, more so than recent, Late Pleistocen...

28 Abstract Lameness is one of the most common problems of musculoskeletal injuries faced by birds especially Ostrich (struthius camales) chicks during brooding period. Mostly it occurs due to fracture in long and their associated bones because of development of pathological condition of bone softening. In avian species, external splints and intramedullary pinning are the most common method to ...

Starting from the biomechanics principle, the three-dimensional (3D) composite model of ostrich foot locomotion system was established using dissection, medical scan modelling, reverse engineering (RE) and finite element (FE) analysis technology. Simulation calculation on the model under three groups of different loads was performed. Meanwhile, plantar pressure test on the in vitro ostrich foot...

BACKGROUND Pyrolysis of slaughterhouse waste could promote more sustainable phosphorus (P) usage through the development of alternative P fertilizers. This study investigated how pyrolysis temperature (220, 350, 550 and 750 °C), rendering before pyrolysis, and wood or corn biomass additions affect P chemistry in bone char, plant availability, and its potential as P fertilizer. RESULTS Linear ...

The Sauropoda were the largest terrestrial animals ever to have lived on this planet. As their nutritional requirements were so huge, their diet holds sway over the ecology of many Mesozoic herbivores. The diet of the sauropods is limited by their feeding envelope, which in turn is governed by the posture and flexibility of their elongate necks. Yet the exact nature of the flexibility and postu...

The removal of inorganic arsenic (As) species from water using bone char pyrolyzed at 900 °C was investigated. Results revealed that the Sips model resulted in best As(III) experimental data fit, while As(V) were represented by Langmuir model. adsorption rate and mechanisms both As investigated kinetic diffusional models, respectively. At low concentrations 0.5 2.5 mg/L, due to intra-particle i...

The application of high-resolution analytical techniques to characterize ancient bone proteins requires clean, efficient extraction to obtain high quality data. Here, we evaluated many different protocols from the literature on ostrich cortical bone and moa cortical bone to evaluate their yield and relative purity using the identification of antibody-antigen complexes on enzyme-linked immunosor...
