In Mexico and the world, the events due to natural disasters that occurred in the last decade have led us to reflect on the commitment of Architecture, it is necessary to understand and measure the responsibility of the architect in disaster areas, it is essential to submit to analysis the teaching of architecture as an agent that generates well-being with social responsibility. The problems that derive from natural disasters, have an impact of considerable duration, the impact of an earthquake for example, not only affects the moment of the event itself, but its consequences infer a wide spectrum of affectations. One of the great concerns is the management and final disposal of waste, in the affected areas of Mexico it is a critical situation, which worsens as the volume of waste generation grows, coupled with it, the customary way its disposal is carried out in open-air dumps, which causes great effects on the natural environment. The environmentally adequate final disposal complicates the capacity of the collection services, the infrastructure and the sanitary landfills, however, the need for their correct handling and control opens the possibility of recycling. This article calls for reflection and presents a research project arising from the classroom, which is based mainly on the design of a mold to create modules as a building element (Block) with the use of construction waste and demolition, as recycled aggregates product of rubble and demolitions, one of the objectives of the project is to verify their effectiveness and thus be able to use them in the reconstruction and construction of another alternative housing at low cost.

Lab-based experiments and observational data have consistently shown that extraverted behavior is associated with elevated levels of positive affect. This association typically holds regardless of one’s dispositional level of trait extraversion, and individuals who enact extraverted behaviors in laboratory settings do not demonstrate costs associated with acting counter-dispositionally. Inspired by these findings, we sought to test the efficacy of week-long ‘enacted extraversion’ interventions. In three studies, participants engaged in fifteen minutes of assigned behaviors in their daily life for five consecutive days. Studies 1 and 2 compared the effect of adding more introverted or extraverted behavior (or a control task). Study 3 compared the effect of adding social extraverted behavior or non-social extraverted behavior (or a control task). We assessed positive affect and several indicators of well-being during pretest (day 1) and post-test (day 7), as well as ‘in-the-moment’ (days 2-6). Participants who engaged in extraverted behavior reported greater levels of positive affect ‘in-the-moment’ when compared to introverted and control behaviors. We did not observe strong evidence to suggest that this effect was more pronounced for dispositional extraverts. The current research explores the effects of extraverted behavior on other indicators of well-being and examines the effectiveness of acting extraverted (both socially and non-socially) as a well-being strategy.

Load scheduling is essential for optimizing power transmission on the system. The way to produce a stable electrical energy transmission system is to minimize transmission losses using between the moment of inertia and power on the generator. The generation noise is a description of the power losses on the transmission line generated when the power plant sends the load power. Transferring power from a high losses plant to a low losses plant. Rescheduling System can minimize transmission system losses. In this research, the scheduling result of this method is compared with the realization of scheduling of thermal generators from PT PLN (Persero) Sulselbar Central Disbursement and Control Center (P3B). This comparison aims to prove this method better than scheduling realized PLN, so that found also advantages and disadvantages method. After the research, this method produces a generation power that is close to stability, because the amount of power generated close to the power generation of PLN in fulfilling the same load demand remains with smaller transmission losses and cheaper fuel costs. The result of stable loading results in the efficiency of the electricity company so that it can reduce the operational cost of the generation and of course indirectly impact on the low cost of electricity production.

Aesthetic moments of revelation – intense, sensual, internal, and individual –are so key to modernist culture that the idea of them in criticism has become commonplace. Here I seek to breath life into this humdrum formula of modernist criticism by exploring multiple responses to an alternative moment amongst British cultural figures: the declaration of War against Germany at 11.15 on September 3rd, 1939. This was also an intense moment, but it was social, political, communal, mediated and disseminated publicly by new technologies. As my archival research here reveals, a wide spectrum of responses were recorded, so we can think of such a moment as ‘prismatic’. I will also show how this moment was a shock to culture, which went into a state of suspended animation. As well as offering critiques of the moment as a fetishised form, I argue that modernist culture and the idea of the moment would never be the same again.

In France, little data are available on mental health and well-being in academia, and nothing has been published about PhD students. From studies abroad, we know that doing a PhD is a difficult experience resulting in high attrition rates with significant financial and human costs. Here we focused on PhD students in biology at university Lyon 1. A first study aimed at measuring the mental health and well-being of PhD students using several generalist and PhD-specific tools. Our results on 136 participants showed that a large fraction of the PhD students experience abnormal levels of stress, depression and anxiety, and their mean well-being score is significantly lower than that of a British reference sample. French PhD student well-being is specifically affected by career uncertainty, perceived lack of progress in the PhD and perceived lack of competence, which points towards possible cultural differences of experiencing a PhD in France and the UK. In a second study, we carried out a positive psychology intervention. Comparing the scores of the test and control groups showed a clear effect of the intervention on reducing anxiety. We discuss our results and the possible future steps to improve French PhD students’ well-being.

This document presents the results obtained from the application of the law of Lens to correctly identify the polarity of the windings in a three-phase motor with 6 exposed terminals, when the corresponding labeling is not in any situation; Prior to identifying the polarity, it should be considered to have the pairs of the three windings located. For the polarity, it is proposed to feed with a voltage of 12 Vrms to one of the windings, which are identified randomly as W1 and W2, where W1 is connected to the voltage phase of 12 Vrms of the signal and W2 to the voltage reference to 0V; by means of voltage induction and considering the law of Lens, the remaining 4 terminals can be identified and labeled as V1, V2, U1 and U2. For this process a microcontroller and control elements with low cost are used.

Rivers are the lifeline of Bangladesh economy and serve as the source of water supply, fisheries, irrigation for agriculture, low-cost transport, generate electricity and conserve biodiversity. The Ichamati River situated in Pabna, Bangladesh is also a blessing for the city. However, recently, due to the irregular and unplanned activities adjacent to the riverside, the life, flow and water quality of the river is in a vulnerable condition. This study aims to identify the present status of the Ichamati River and provide an effective design approach and policy measures in restoring the river flow and control water pollution. The data was collected from the questioner surveys, key informant interviews and focus group discussions. Results suggest that several factors such as the construction of an illegal settlement, unplanned waste dumping, disposal of fiscal sludge through sewerage connection, lack of awareness among people regarding the importance of river biodiversity and absence of riverfront development and conservation plan are responsible for water pollution, inconsistent water flow and damaging the life cycle of Ichamati river. The design approach and policy measures were developed based on the perceptions of local community people, experts and government officials. The suggested policy measures will help to restore the flow of the river and reduce the water pollution, and the design approach will ensure the economic benefit of the riverfront development in future.
