TL;DR: A fully three-dimensional approach is used for computer simulation of tissue differentiation and bone regeneration in a regular scaffold as a function of porosity, Young's modulus, and dissolution rate, showing that scaffolds may be optimised to suit the site-specific loading requirements.

TL;DR: In this article, an experimental investigation has been carried out in order to evaluate the detection of cavitation in actual hydraulic turbines, based on the analysis of structural vibrations, acoustic emissions and hydrodynamic pressures measured in the machine.

TL;DR: In this paper, a review of the requirements set by Grid Codes, but also on control methods of wind turbines for their participation in primary frequency control and synthetic inertia is presented. But the authors do not consider the effect of non-synchronized renewable-based power plants (e.g., wind and solar).
Abstract: Active power reserves are needed for the proper operation of an electrical system. These reserves are continuously regulated in order to match the generation and consumption in the system and thus, to maintain a constant electrical frequency. They are usually provided by synchronized conventional generating units such as hydraulic or thermal power plants. With the progressive displacement of these generating plants by non-synchronized renewable-based power plants (e.g. wind and solar) the net level of synchronous power reserves in the system becomes reduced. Therefore, wind power plants are required, according to some European Grid Codes, to also provide power reserves like conventional generating units do. This paper focuses not only on the review of the requirements set by Grid Codes, but also on control methods of wind turbines for their participation in primary frequency control and synthetic inertia.

TL;DR: It is shown that the higher specific surface, produced by the reduction of the particle size of the powder, strongly accelerates the hydrolysis of the alpha-TCP into calcium-deficient hydroxyapatite, and favours the nucleation of smaller crystals.

TL;DR: In this paper, the authors identify the key aspects of transformation of universities towards sustainability, such as the ideal characteristics of the sustainable university, and the drivers and barriers in the transformation, by comparing the strategies of seven universities world-wide.
Abstract: Purpose – The purpose of this paper is to identify the key aspects of transformation of universities towards sustainability, such as the ideal characteristics of the “sustainable university”, and the drivers and barriers in the transformation, by comparing the strategies of seven universities world-wide. Design/methodology/approach – A systems transformation analysis of seven case studies has been applied through a self-evaluation based on the tridimensional Framework-Level-Actors (FLA) method. Findings – The study shows that none of the three dimensions of change is predominant over the others. The main barrier to be overcome is the lack of incentive structure for promoting changes at the individual level. The main drivers for change are the presence of “connectors” with society, the existence of coordination bodies and projects, and the availability of funding, all of which are important for progress. Enhancing interdisciplinarity is a strategic objective at almost all of these universities, while transformative learning is less present. A common characteristic for most of the institutions is establishing and supporting networks of expertise within the universities. These universities show important strategic efforts and initiatives that drive and nucleate change for sustainable development, the result of a combination of drivers. Practical implications – The FLA-method has proved useful for being used at the level of comparing case-studies through a bird’s-eye perspective. Originality/value – The paper demonstrates the application of a simple tool that gives a global perspective on transformational strategies used in seven cases world-wide in the search for commonalities and differences.
