As the development characteristics of cracks of the chamber are closely related to the bolt and cable anchoring parameters, the original rock Outdoor Tools stress of the surrounding rock, and fracture degree, this paper proposes the control method for chamber in extra-thick coal seam by the crack development characteristics.Based on the numerical m
Abstract Background To date very few systems have been described for preclinical investigations of human cellular therapeutics in vivo.However, the ability to carry out comparisons of new cellular vaccines in vivo would be of substantial interest for design of clinical studies.Here we describe a humanized mouse model to assess the efficacy of vario
Thin films of nanocomposite of zinc oxide−reduced graphene oxide (ZnO-rGO) deposited on soda-lime glass substrates were prepared using ultrasonic spray pyrolysis (USP) at 460 °C.The preparation process does not use harsh acids and is environmentally friendly.The deposition period of 2, 3.5 and 5 min resulted in compact, uniform samples w
Abstract Background Biomechanical parameters can distinguish a skilled rower from a less skilled rower and can provide coaches with meaningful feedback and objective evidence to inform coaching practices on rowing technique.Therefore, it is critical to understand which technical characteristics can be related to the fundamental rowing performance i
Is a group best off if everyone co-operates? Theory often considers this to be so (e.g.the "conspiracy of doves"), this understanding underpinning social and economic policy.We observe, however, that after competition between "cheat" and "co-operator" strains of yeast, population fitness is maximized under co-existence.To address whether this might
