    War and Peace. The Film Iconeme of the Urban Square as Image of Europe in Transition (1944-1948)

    A central feature of European urban landscapes, the square represents the public space par excellence. At the end of WW2 and in the immediate postwar time, the role of cinema in representing and reimagining urban squares was crucial. Through film images, they became the stage and the mirror of a Europe in transition. This contribution, examining Italian, French, German, and Czechoslovak cases, posits the square as an essential iconeme in postwar nonfiction cinema and visual culture, acting as a fil rouge to visually retrace the path of Europe from war to peace, and into new forms of political tension

    Kinetics of leucine transport in brush border membrane vesicles from lepidopteran larvae midgut.

    The kinetics of K(+)-leucine cotransport in the midgut of lepidopteran larvae was investigated using brush border membrane vesicles. Initial rate (3 s) of leucine uptake was determined under experimental conditions similar to those occurring in vivo, i.e. in the presence of delta psi much greater than 0 (inside negative) and a delta pH of 1.4 units (7.4in/8.8out). Leucine and K+ bind to the carrier according to a sequential mechanism, and the binding of one substrate changed the dissociation constant for the other substrate by a factor of 0.15. Both trans-K+ and trans-leucine were mixed-type inhibitors of leucine uptake. Moreover, a portion of total leucine uptake was K+ independent, and it was competitively inhibited by trans-leucine. We interpret the trans inhibitory effects to mean that the partially loaded K+ only form is virtually unable to translocate across the membrane, whereas the binary complex carrier, leucine, can isomerize from the trans to the cis side of the membrane. However, the K(+)-independent leucine uptake occurs with a Keq greater than 1, i.e. the efflux route through the partially loaded leucine only form is slower than the rate of isomerization of the unloaded carrier from trans to cis side. Taken together, these results suggest a model in which transport occurs by an iso-random Bi Bi system. Since K+ does not act as a pure competitive activator, this model is different from that proposed for most of the Na(+)-linked solutes transport agencies and may be related to the broadening of the cation specificity of the amino acid transporters in lepidopteran larvae

    A hybrid multi-step approach for urban area mapping in the Province of Milan, Italy

    AbstractRemote sensing products have proven an effective tool for the study of urban areas, from city management to environmental monitoring. This work focuses on the mapping of urban areas in the Province of Milan, Northern Italy, using mid-resolution remote sensing data covering the last 20 years. The methodology consists of three main steps: (i) a pixel-based classification tree, (ii) object-based filtering of agricultural terrain, and (iii) joining of land cover classes into two (urbanized and non-urbanized), adding post-classification editing. The final derived urban maps were validated and demonstrated to reach very good accuracy (error: 7–13%), thus providing reliable thematic information for urban planning of local and regional authorities

    Sustainable House Manufacturing for Smart Matching Cities

    In bottom-up approach to the smart city, the construction of the house and its related land consumption is the fundamental cell for governing urban development and its sustainable relationship with society and the rural area. Given the situation in northern Argentina, the research outlines a construction system based on the sustainable wood supply chain, with industrialized production of wood wafer panels and the proposal of a deconstructible house whose elements can be transported by truck. Sustainability of the building system is achieved through the use of wood from rotational forests and the proposed re-purposing of river and rail transport, while building sustainability is pursued through the integrated use of photovoltaics, heat pump, rainwater and surface geothermal energy. The designed dwelling envelope results B rated, according to the IRAM 11605 Argentine standard and the “Minimum Quality Standards for Social Housing”

    AUTOMATED ANOMALY MONITORING AND DETECTION SYSTEM FOR FCU SYSTEM

    Implementing and integrating new technologies such as the Internet of Things (IoT), smart sensors, and information and communication technology (ICT) into building facilities generates a large amount of data that will be utilized to better manage building facilities specifically FCU. Automated fault detection and diagnostics(AFDD) systems assist facility managers in informing operators to perform scheduled maintenance and visualizing facility anomalies on building information models (BIM). This study proposes a AFDD system for FCU system using an IoT sensors and by visualizing faults in a BIM model. The proposed system shows the data management and anomaly detection and monitoring technique on the BIM. The experiment results demonstrated the framework's competence to detect anomalies in the FCU system. Furthermore, data collected from various simulated conditions of the building facilities was utilized to monitor and detect anomalies in the 3D model of the fan coil. The automated detection FCU anomalies on the BIM model and preliminary results of the system are demonstrated
