We investigate experimentally the depositions of two contiguous debris flows flowing into a main river *** aim of the present experimental research is to analyze the geometry and the mutual interactions of debris flow deposits conveyed by these tributaries in the main channel.A set of 19 experiments has been conducted considering three values of the confluence angle,two slopes of the tributary,and three different triggering conditions(debris flows occurring simultaneously in the tributaries,or occurring first either in the upstream or in the downstream tributary).The flow rate along the main channel was always kept *** each experiment the two tributaries had the same slope and confluence *** analysis of the data collected during the experimental tests indicates that the volume of the debris fan is mainly controlled by the slope angle,as expected,while the shape of the debris deposit is strongly influenced by the confluence ***,in the case of multiple debris flows,the deposit shape is sensitive to the triggering *** index for damming formation available in literature has been considered and applied to the present case,and,on the basis of the collected data,considerations about possible extension of such indexes to the case of multiple confluences are finally proposed.

Membrane separation systems could be a feasible option as post combustion carbon capture technologies in coal-fired power *** advancement on membrane materials based on microporous super glassy polymers could improve significantly the capture process but the properties of the materials have to guide the design of the separation stage. In this study an advanced hybrid two-stage membrane process employing one of the most permeable polymer known(PIM-1) is retrofitted to a coal fired power plant and the process is analysed in terms of energy requirement and cost performance. The results are based on the use of an in-house detailed membrane module model implemented in UniSim Design~?, the Honeywell process flowsheet simulator. The study indicates the need for advanced configuration in order for highly permeable membranes to be competitive with more mature technologies in terms of capture cost. The effect of ageing and impurities on the material is also investigated in order to predict the decline in process performance over time and suggest a timeproof design.

This paper is the second of two companion papers addressing the dynamics of two coupled masses sliding on analytical surfaces and interacting with one another. The motion occurs under the effect of gravity, the reaction force of the surface and basal friction. The interaction force maintains the masses at a fixed distance and lies on the line connecting them. The equations of motion form a system of ordinary differential equations that are solved through a fourth-order Runge–Kutta numerical scheme. In the first paper we considered an approximate method holding when the line joining the masses is almost tangent to the surface at the instant mass positions. In this second paper we provide a general solution. Firstly, we present special cases in which the system has exact solutions. Second, we consider a series of numerical examples where the interest is focused on the trajectories of the masses and on the intensity and changes of the interaction force.

Inaugurated in June 2012, the Carapace at Castelbuono Estate Winery in Italy is a highly interesting example of biomorphic architecture. The structure, an artistic creation of world-renowned sculptor Arnatdo Pomodoro, is reminiscent of a tortoise shell that conveys a sense of protection： the Carapace structure guards wine barriques in the same way that the tortoise carapace protects the animal. Zoomorphic aspects are further exhibited by symbots on the roof, which remind observers of cuttlefish bone, a recurring element in the artistic production of Maestro Pomodoro. The roof was constructed by assembly of single copper plates with a rough surface in accordance with the design of the artist. Therefore, determining the appropriate production process was crucial. Etectroforming was selected as the method to achieve a challenging architectural goal.

Targeted precision neuroendocrine neoplasms (NEN) surgery may represent an innovative, yet promising, development of surgical procedures to achieve a radical resection of the primary tumour (by intra-operative confirmation of tumour-free margins) and to improve the identification of small sized lesions (that might otherwise be missed by either pre-operative functional imaging, ultrasound or manual palpation during surgery). From a practical point of view, radioguided surgery (RGS) requires a close collaboration between the nuclear medicine and the surgical teams, so that a small amount of radiopharmaceutical is intravenously injected in the patient right before surgery. The tumour lesions’ emitted radiation is then detected by a hand-held probe by the surgeon intra-operatively.

Over the past 15 years, housing supply for university students has increased significantly given the considerable attention provided by national institutions on the issue of student housing. In Italy, however, only approximately 4% of students live in university residences. Since 2001, interventions on existing buildings have accounted for approximately 60% of the overall measures proposed for new university residences; these interventions comprise most of the available public economic resources. The possibility of recovering and reusing existing buildings for university residences is remarkable for the city of Catania because most of the students are enrolled in university courses located within the historic city center. Moreover, abandoned buildings are currently a significant part of the city׳s architectural heritage. This research aims to develop an articulated and integrated set of frameworks to support the various phases of the design process for recovering and then reusing existing buildings as university residences. The proposed approach applies existing dimensional standards and environmental sustainability principles to a constructed building using traditional techniques.

In this study, we introduce a system of differential equations describing the motion of a single point mass or of two interacting point masses on a surface, that is solved by a fourth-order explicit Runge–Kutta(RK4) scheme. The forces acting on the masses are gravity, the reaction force of the surface, friction, and, in case of two masses, their mutual interaction force. This latter is introduced by imposing that the geometrical distance between the coupled masses is constant. The solution is computed under the assumption that the point masses strictly slide on the surface, without leaping or rolling. To avoid complications stemming from numerical errors related to real topographies that are only known over discrete grids, we restrict our attention to simulations on analytical continuous surfaces. This study sets the basis for a generalization to more complex systems of masses, such as chains or matrices of blocks that are often used to model complex processes such as landslides and rockfalls. The results shown in this paper provide a background for a companion paper in which the system of equations is generalized, and different geometries are presented.
