Cross-Section Resistivity Detection of Tree (Swietenia Magahoni and Gmelina) Using ERT Method

The existence of trees is very beneficial for humans’ life. There are utilizations of tree such as urban planning and reforestation. However, the tree can be dangerous when the tree is aged and decay because of several factors that might be cause fallen tree. Furthermore, the monitoring activity is needed to know the condition of the tree. One of the methods that can be used to detect hollow in living tree is Electrical Resistivity Tomography (ERT). The ERT is an efficient and nondestructive method that can be potential to estimate resistivity cross section. The measurement of ERT conducted on Swietenia mahagoni and Gmelina with unhealthy and healthy condition visually. The data processed using Res2Dinv and reconstructed for obtaining 2D resistivity cross section. The results shows that the unhealthy Swietenia mahagoni has logarithmic resistivity value range between 0.1-1 Ωm and the healthy Swietenia mahagoni has 1-4 Ωm. Meanwhile, the unhealthy and healthy Gmelina has logarithmic resistivity value range between 0.5-4.5 Ωm and 0.5-3 Ωm, respectively. It is shows that the tree indicated health visually from biological view does not mean the tree is decay. It might be influenced by phenology factor and/or the species of the tree.

Indicators for the evaluation and monitoring activity оf the university incubator

The purpose of the article is to propose the indicators for the evaluation and monitoring activity, thedeveloping structure and functioning of business incubators located in the academic environment whichwould allow the organization of internal and external processes for researchers and students. The success ofa business incubator in the university environment represents primarily its value for the university and for theeconomic environment and the ability to react quickly to changing conditions inside and outside and developing the entrepreneurial ecosystem at national level. The degree of development of university incubators, thecapacity and quality of their functioning depends not only on the intensity of the support of the environment inwhich they operate, but also on their efficiency through attractiveness, promoting viable businesses and atthe same time being an alternative source of financing and propelling potential entrepreneurs.

Floating structure prototype for supporting UAV on water surface is described, taking into account creating a rotor thrust theory. Water hydrogen ions monitoring activity concept using a UAV is presented. Testing results water monitoring system in Lake Boyarskoye (Tomsk, Russia) are presented.

A multi-site, year-round turbulence microstructure atlas for the deep perialpine Lake Garda

A multi-site, year-round dataset comprising a total of 606 high-resolution turbulence microstructure profiles of shear and temperature gradient in the upper 100 m depth is made available for Lake Garda (Italy). Concurrent meteorological data were measured from the fieldwork boat at the location of the turbulence measurements. During the fieldwork campaign (March 2017-June 2018), four different sites were sampled on a monthly basis, following a standardized protocol in terms of time-of-day and locations of the measurements. Additional monitoring activity included a 24-h campaign and sampling at other sites. Turbulence quantities were estimated, quality-checked, and merged with water quality and meteorological data to produce a unique turbulence atlas for a lake. The dataset is open to a wide range of possible applications, including research on the variability of turbulent mixing across seasons and sites (demersal vs pelagic zones) and driven by different factors (lake-valley breezes vs buoyancy-driven convection), validation of hydrodynamic lake models, as well as technical studies on the use of shear and temperature microstructure sensors.

Hydro-acoustic signals from the Panarea shallow hydrothermal field: new inferences of a direct link with Stromboli

We present the results from a mid-term monitoring activity carried out at the submarine hydrothermal system located off Panarea island (Aeolian Islands, Italy). The collected data concern multiparametric information from a self-operating seafloor station (acoustics and chemical-physical parameters) acquiring at regular intervals and transmitting data twice a day in near real-time. The acoustic records were analysed with the principal aim of investigating bubbling variations related to gas flow rate. Several anomalies have been documented, in the bubbling activity detected at high frequencies (100-2000 Hz), as well as in very low acoustic frequencies, related to fluids dynamic along cracks. An astonishing correlation between soil CO2 flux emissions recorded at Stromboli craters, and the acoustic signals in the 1-30 Hz range has been identified, suggesting how this tectonic link could act as an escape route for fluids characterized by a shared source.

Preface to “Understanding volcanic processes through geophysical and volcanological data investigations: some case studies from Italian sites (EGU2019 GMPV5.11 session, COV10 S01.11 session)”

Volcanic dynamics is driven by the complex interplay between fluid flow (circulation of magmatic and/or hydrothermal fluids) and rock structure (volcano conduits, dykes), the comprehension of which requires both multi-parametric monitoring and modelling of relevant physical and chemical processes of the system. Understanding the factors controlling the dynamics of the processes involved in these interactions is necessary to characterize the overall behaviour of a volcano and the eventual transition mechanisms among stationarity, unrest phases and eruptive styles. The starting point in this context is to have high-quality data of several parameters (seismological, geochemical, geodetic, volcanological), acquired both over years of monitoring activity and focused field experiments. Fundamental contributions come from the use of combined multi-parametric datasets and the adoption of innovative analysis techniques and multi-disciplinary approaches. This Special Issue is addressed to those researchers, who focus their investigations in the field of volcano dynamics. Its main purpose is to shed light on the processes occurring in active volcanic systems over different time scales, with relevant implications for the hazards and the modern monitoring, thus promoting future discussions on this topic. The Issue contains this introducing preface, which describes the Volume aims, and 14 papers, reflecting the main themes. The papers are devoted to the study of some Italian sites, but the proposed approaches are general and therefore applicable to any other volcanic/hydrothermal areas.

Design and Covid-19: Monitoring Urban Data

This article discusses the use of population monitoring within urban space by designers. It considers its use to define design strategies aiming at mitigating the Covid-19. Some governments have used identified citizens data as well as stored population data through telephone companies. In search to establish new strategies to mitigate the pandemic consolidation, data collected are used for communication, considering among other aspects statistical surveys of the population. With this, new services are offering digital applications in the pandemic context, having designers as part of the group of people involved in this new process. On population monitoring activity, issues such as data privacy, surveillance capitalism and doubts about the use of these data and activities after the pandemic are points to be considered. In this context, how and what should designers consider in this scenario is a question that arises. This work presents a discussion about the theme based upon a systematic research on the related literature. Literature was analysed resulting in a set of points that shows the importance of design strategy in the use of these projects.
