Coffee biowaste valorization within circular economy: an evaluation method of spent coffee grounds potentials for mortar production
2021
Abstract Purpose Spent coffee grounds (SCG) are biowastes extensively generated within the coffee supply chain. Nowadays, their disposal represents an increasing environmental concern due to its toxicity and organic nature. With the estimated increase of coffee production and consumption in the upcoming years, there is an imperative need to find a proper reverse option, along with a novel industrial application, which allows for the valorization of this coffee by-product within a circular economy perspective. This study aims at investigating a potential reuse of spent coffee grounds to produce novel construction materials to be used for sustainable buildings. Methods After having illustrate…
The emergence of lean construction in the Norwegian AEC industry
2021
Lean construction has inspired the AEC industry globally over the last decades, and this manifests within a wide array of contexts. The purpose of this paper is to provide a narrative-based qualitative analysis of the emergence and impact of Lean construction on a national level, notably in the Norwegian AEC industry. The analysis is based on the concept of paradigm shift and on empirical knowledge in the form of narratives. The narratives of practitioners and researchers provide deep insights into how Lean Construction has inspired the Norwegian AEC industry and academia, respectively. The reflections indicate that the introduction of the Lean construction principles and tools in the Norwe…
Dynamic Ordering of Firewall Rules Using a Novel Swapping Window-based Paradigm
2016
Designing and implementing efficient firewall strategies in the age of the Internet of Things (IoT) is far from trivial. This is because, as time proceeds, an increasing number of devices will be connected, accessed and controlled on the Internet. Additionally, an ever-increasingly amount of sensitive information will be stored on various networks. A good and effi- cient firewall strategy will attempt to secure this information, and to also manage the large amount of inevitable network traffic that these devices create. The goal of this paper is to propose a framework for designing optimized firewalls for the IoT. This paper deals with two fundamental challenges/problems encountered in such…
Adaptive use patterns of secondary school classroom environments
2006
Purpose – The purpose of this research is to investigate how secondary school teachers adaptively make use of the classroom learning environment. The approach illustrates the intimate relationship between teaching style, learning style and the adaptive use of space as well as the preferences for different learning environments.Design/methodology/approach – A multi method study approach was used to carry out the research. Two main methods were used in the study. In the first method, trainee teachers recorded spatial observations (mapping). Maps of the chemistry classrooms were produced. The observers marked all fixed, semi‐fixed and flexible elements in the classroom space. The second method…
Patrimonio etnológico e identidades en España: Un estudio comparativo a través de la legislación
2008
Beatriz.Santamarina@uv.es; gil.hernandez@uv.es; Albert.Moncusi@uv.es Este artículo es una aproximación a cómo la legislación española construye el patrimonio cultural o histórico y el patrimonio etnológico a través de una ampliación de contenidos y una vinculación a un determinado colectivo de referencia. Para ello, se analizan los discursos de las leyes autonómicas de Patrimonio teniendo también en cuenta la ley de Patrimonio Histórico, de 1985. El análisis realizado permite observar, para el caso español, el carácter diverso y difuso del concepto de patrimonio etnológico y la relevancia de las leyes autonómicas de patrimonio cultural para la sustentación de los regionalismos y nacionalism…
Visiones y mentalidad arquitectónica de un maestro del siglo XVIII. "La Descripción breve de las medidas y magnificencia..." del Convento de Santa Cl…
2005
Presentamos el texto inédito de fray José Alberto Pina (1693-1772) titulado: "Descripcion breve de (...) el Real Monasterio de (...) Santa Clara", redactado a mediados del siglo XVIII, en el que describe pormenorizadamente este convento de la ciudad de Xátiva (Valencia), donde se manifiesta la formación técnica y constructiva de su autor, y una semblanza de su personalidad arquitectónica.

Recent developments, current challenges, and future directions in electrophysiological approaches to studying intelligence
2021
Abstract EEG studies represent an important sub-discipline in the field of intelligence research and have significant potential to advance the theoretical understanding and practical applications of the construct. This commentary reviews key themes and major developments in the field from the last several decades, and outlines open questions and future directions for the next phase of research. Two main areas of progress in recent years relate to (1) improvements in study design and psychometric approaches, and (2) increased integration with cognitive psychology and neuroscience. In turn, these advances have clarified several themes and pressing issues. These include: The need to establish …
A critical review of life cycle assessment benchmarking methodologies for construction materials
2022
As it stands, the construction sector accounts for a significant proportion of global emissions. The majority of these emissions can be associated with material production. As a result, the importance of quantifying these environmental impacts is continually increasing. However, there is a current lack of guidance and methodologies regarding how to benchmark the impacts of construction products, and thus achieve more transparent environmental reporting and decision-making. Therefore, the aim of this study was to review engineering life-cycle assessment (LCA) literature and applicable standards to identify the key methodological variables required and the key steps for a sector-wide methodol…
Issues and Perspectives in the Application of Different Pavement Design Methods to Life Cycle Cost Analysis
2016
Life cycle costs analysis (LCCA) is an economic evaluation tool that can provide valuable guidance to transportation officials in management decision process. The application of LCCA to pavement management is vital because it permits the selection of the best alternative, based on the analysis of agency costs and user costs, taking into account (after selecting pavement type) different maintenance and rehabilitation (M&R) strategies within the same pavement type. Additionally, environmental costs can be considered. Issues arise when comparing the expected life of the pavement derived according to different pavement design tools, such as the Mechanistic-Empirical pavement Design Guide (M…
Beauty and the Cosmetic Secret
2018
Cosmetic surgery is often linked to the perception that women who resort to cosmetic interventions to alter their physical appearance are vain, superficial, and narcissistic. Few investigations have acknowledged and explored the individual’s personal motivations and experiences of her action and choice with regards to aesthetic surgery. By focusing on subjective experience, alternative insights can be gained on the cosmetic procedure(s) and on how their reshaped body influences an individual’s lifeworld experience. The article explores the perceived benefits and consequences of reshaping, enhancing, and/or reducing a perceived flaw or shortcoming of the body. From this exploration the focus…
