Los niveles de contaminación ambiental provocados por la industria han sobrepasado la capacidad del planeta, en este resultado tiene una responsabilidad importante el diseñador de productos, por ello juega un papel sustancial la ética del diseñador en lo que respecta a la sustentabilidad. Las innovaciones de los biomateriales brindan una oportunidad en esa reivindicación, es así que, la investigación pretende a través de la aplicación de la celulosa bacteriana obtener nuevas posibilidades para la industria del diseño y cuidado del medio ambiente reduciendo los niveles de basura que generan los materiales comunes, debido a que este material celulósico es considerado como sustentable y de carácter renovable. Se planteó el desarrollo de los productos a través de la ruta metodológica ARZ, que coloca los criterios de sustentabilidad como eje de inicio y final al momento de plasmar la necesidad, ideación, venta, uso y desuso del nuevo producto. Como resultado se obtuvo un biomaterial con características fisicoquímicas y mecánicas que permitieron la aplicación en tres series de productos: calzado, carteras y bisutería. La sustentabilidad es la opción del nuevo pensamiento productivo del diseño y de los diseñadores, es decir, crear con responsabilidad social y ambiental. Palabras clave: Celulosa bacteriana, biomateriales, diseño ético, diseño sustentable, diseño de producto. AbstractThe levels of environmental pollution caused by the industry have exceeded the capacity of the planet. The product designer has an important responsibility for this result, therefore, the ethic of the designer takes a substantial role related to sustainability. The innovations of biomaterials provide an opportunity in this claim, and so, this research aims to obtain new possibilities for the design industry and care for the environment through the application of bacterial cellulose in order to reduce the levels of waste that is generated by the common materials because this cellulosic material is considered sustainable and renewable. The development of the products was proposed through the ARZ methodological route that places the sustainability criteria as the starting and ending axis at the moment of reflecting the need, ideation, sale, use, and obsolescence of the new product. Consequently, a biomaterial is obtained with physicochemical and mechanical characteristics that allowed its application in three series of products: footwear, handbags, and costume jewelry. Sustainability is the option of the new productive thought of the design, as well as the designers; that means, creating with social and environmental responsibility.Keywords: Bacterial cellulose, biomaterials, ethical design, product design, sustainable design.

The Austrian school of economics and the investment method known as value investing have a similar conception of the world, so that it is possible to find multiple links between them and form a coherent structure. To the economist, this allows for a much deeper understanding of the entrepreneurial function and the manner in which economic calculation is actually performed. To the investor, it offers a theoretical framework that explains economic phenomena, permitting him to better understand the role of the entrepreneur and to protect his investment when dangerous patterns can be observed. In this essay, we begin from the common stance of both schools of thought towards common sense, the use of realistic assumptions, the importance of prudence and the low value of complex mathematics in the fields of economics and finance. We then proceed to develop in greater depth nine aspects that have strong philosophical and scientific links. Key words: Value investing, Austrian school of economics, entrepreneurship, dynamic efficiency, economic calculation. JEL Classification: A12, G17, M20. Resumen: La Escuela Austriaca de Economía y el método de inversión en valor tienen una concepción similar del mundo que permite entrelazarlas coherentemente. Al economista, le permite profundizar el conocimiento del ejercicio de la función empresarial y la realización del cálculo económico en la práctica. Al inversor, le ofrece un marco teórico para comprender mejor el papel del empresario y los fenómenos económicos y detectar temprano patrones peligrosos y así protegerse. En este trabajo partimos de la base de que ambas escuelas de pensamiento tienen sus raíces en el sentido común y los supuestos realistas, que son prudentes a la hora de ver el futuro y que dudan de la utilidad de las matemáticas complejas en los campos económicos y financieros. Sobre ello, desarrollamos nueve aspectos en los cuales hay fuertes conexiones como, por ejemplo, la manera en que el ejercicio de la empresarialidad mejora la eficiencia del mercado y coordina los planes de las personas.

Resumen. Esta investigación se enmarca en el estudio del proceso de configuración de destinos turísticos rurales, en el cual se investiga la transición de territorio a destino. El objetivo de este trabajo es analizar el proceso de distanciamiento en el medio rural, identificado gracias a las potencialidades derivadas del uso de la triple codificación que caracteriza la Grounded Theory. El distanciamiento es definido como una desterritorialización multidimensional y caracterizado por cuatro rupturas: socioproductiva, sociocultural, socioambiental y política. Este proceso se identifica como el momento en el cual un territorio oscila entre el declive y la reconstrucción para el impulso del desarrollo territorial basado en las especificidades del territorio. Es una investigación cualitativa inductiva, realizada a partir de la perspectiva glaseriana de la Grounded Theory como metodología de investigación y análisis. Aborda la desterritorialización desde una perspectiva filosófica y económica para explicar el proceso de distanciamiento. Una fase de conceptualización del territorio previa a la construcción de destinos turísticos en el medio rural.   Palabras clave: Grounded Theory, distanciamiento, desterritorialización.   Abstract. This research is part of the study of the process of configuration of rural tourist destinations, in which the transition from territory to destination is researched. The aim of this paper is to analyze the process of distancing in the rural environment, identified thanks to the potentialities derived from the use of the triple coding that characterizes the Grounded Theory. Distancing is defined as a multidimensional deterritorialization, characterized by four ruptures: socio-productive, socio-cultural, socio-environmental and political. This process is identified as the moment in which a territory oscillates between decline and reconstruction in order to promote territorial development based on the specificities of the territory. It is a qualitative inductive research, carried out from the glaserian perspective of the Grounded Theory as a research and analysis methodology. It approaches deterritorialization from a philosophical and economic perspective to explain the process of distancing. A phase of conceptualization of the territory prior to the construction of tourist destinations in the rural areas.   Key words: Grounded Theory, distancing, deterritorialization.

The work objective is to determine the parameters of the closing mechanism that provide the specified characteristics of the door movement. Research method: computer simulation of the movement of a door with a lock mechanism as a multi-mass dynamic system, taking into account the mechanical characteristics and contact interaction of the lock mechanism. Research results and novelty. Computer dynamic models of a door with a door closer and a door with a spring have been developed. The moments of the door opening force, the closing time of the door, the angular velocity of the door at the time of impact with the frame are considered as the criteria for the quality of the door closing mechanism. Formulas are obtained that determine the permissible values of stiffness and deformation of the door closer spring according to the specified moments of the door opening force. The movement of doors with a door closer and with a spring is compared. The parameters of the closing mechanism providing the specified characteristics of the door movement of the considered example are determined. It is shown that with the same values of the opening force moments, the speed of impact with the frame in the case of the door closer is less than the door with a spring. Conclusions: The developed computer dynamic models of a door with a door closer and a door with a spring make it possible to determine the characteristics of the door movement taking into account the inertial and mechanical characteristics of the door closer and spring mechanisms. The permissible values of stiffness and deformation of the door closer spring can be determined by the specified moments of the door opening force in two positions. It is established that the forces of air resistance and friction in the hinges of the door cannot create the moment of resistance necessary for smooth closing of the door without a strong impact on the frame with a limited closing time. The quality criteria that minimize the closing time and the speed of impact of the door with the frame are contradictory. The choice of optimal parameters of the door closing mechanism is possible if one of the criteria is replaced by a restriction. The developed formulas and computer models are recommended for use in the design of devices that restrict the movement of doors.

The manufacture of mechanical components by means of biodegradable composites is the best alternative at the moment of reducing cost and weight, maintaining the mechanical characteristics. In this work the mechanical characteristics are shown as the result of combining a polyester matrix resin with a reinforcement of animal fiber such as horsehair. The results obtained correspond to mechanical characterization tests at traction, bending and impact by dart drop according to rules ASTM D3039/D3039M-17, D7264/D7264M-15 and D5628 respectively, made in four groups of test pieces of material combining a polyester matrix resin and reinforcement of horsemane. The development of materials composed of horsehair as reinforcements offers similar mechanical characteristics with traditional materials such as sheet steel or polymers, but with a considerable weight reduction, ideal for automotive applications such as bodywork or interior parts of vehicles.

SummaryAlthough hospitals primarily provide treatment for in-patients, treatment is also given to a large number of out-patients. The law covering haemophilia patients, who receive their treatment as out-patients, actually has several different bases. This has advantages and disadvantages. The question concerning us: Which, at the moment, is the best legal basis for any care-agreement? Another important factor for any agreement between the two parties, is that there should be a broad consensus, based on shared interests.The common aim should be the future guarantee for the treatment of patients suffering from haemophilia in suitable medical facilities. At the same time care must be taken to provide an efficient and economically viable care-service for these patients, as well as ensuring that the quality and efficiency of the service remain transparent.

Abstract Close double neutron stars (DNSs) have been observed as Galactic radio pulsars, while their mergers have been detected as gamma-ray bursts and gravitational wave sources. They are believed to have experienced at least one common envelope episode (CEE) during their evolution prior to DNS formation. In the last decades, there have been numerous efforts to understand the details of the common envelope (CE) phase, but its computational modelling remains challenging. We present and discuss the properties of the donor and the binary at the onset of the Roche lobe overflow (RLOF) leading to these CEEs as predicted by rapid binary population synthesis models. These properties can be used as initial conditions for detailed simulations of the CE phase. There are three distinctive populations, classified by the evolutionary stage of the donor at the moment of the onset of the RLOF: giant donors with fully convective envelopes, cool donors with partially convective envelopes, and hot donors with radiative envelopes. We also estimate that, for standard assumptions, tides would not circularise a large fraction of these systems by the onset of RLOF. This makes the study and understanding of eccentric mass-transferring systems relevant for DNS populations.

Gait energy image (GEI) preserves the dynamic and static information of a gait sequence. The common static information includes the appearance and shape of the human body and the dynamic information includes the variation of frequency and phase. However, there is no consideration of the time that normalizes each silhouette within the GEI. As regards this problem, this paper proposed the accumulated frame difference energy image (AFDEI), which can reflect the time characteristics. The fusion of the moment invariants extracted from GEI and AFDEI was selected as the gait feature. Then, gait recognition was accomplished using the nearest neighbor classifier based on the Euclidean distance. Finally, to verify the performance, the proposed algorithm was compared with the GEI + 2D-PCA and SFDEI + HMM on the CASIA-B gait database. The experimental results have shown that the proposed algorithm performs better than GEI + 2D-PCA and SFDEI + HMM and meets the real-time requirements.

In the context of refurbishment projects, providing a safety and health checklist could assist in reducing noncompliance with health and safety regulations and would lead to improvement in communication between different participants in refurbishment projects. The practical checklist for refurbishment project is developed by revising current demolition checklist since there is no specific checklist applicable for refurbishment work at the moment. To achieve this target, demolition techniques, methods and accident reports on the refurbishment project is critically reviewed and investigated. A semi-structured interview based on reviewed literature and existing demolition checklist is organized which addresses a panel of Malaysian refurbishment experts and workers. The final results are provided by analyzing the response of interviewees in listing the common hazards occurring in the site and their recommendations regarding to appropriate precautions to prevent accidents in work site. Finally, refurbishment checklist is developed based on different categories of work phase, activities, precautionary actions and recommendations in which contents directly extracted from data collection and literature review.
