  • A Brief History of Stevens` 116 Year Chart Recorder Legacy

    The legendary mechanical chart recorder for environmental monitoring dates back to 1911, when John C. Stevens invented the Type A chart recorder. In 1906, J.C. Stevens was the Hydrographer for the USGS out of Portland, Oregon, and was soon promoted to District Engineer.  While with the USGS, he realized that hiring local citizens to observe and record height of water was not accurate or ...

  • The first monitoring well in Engbertsdijksvenen is a reality

    On Wednesday 20 December 2017, the first monitoring well of the groundwater monitoring network Engbertsdijksvenen was realised on the parcel of landowner Wilharms in Vriezenveen. This monitoring well serves to monitor the effects of the measures required for the Nature Objectives of the Engbertsdijksveen. One of these goals is the recovery of living high moor. In addition to this monitoring well, ...

  • Adsorption behavior of methyl orange onto an aluminum-based metal organic framework, MIL-68(Al)

    MIL-68(Al), a powdered aluminum-based metal organic framework (MOF), was synthesized and used to explore its adsorption behavior toward methyl orange (MO). The adsorption isotherm, thermodynamics, kinetics, and some key operating factors as well as changes in the material's structure were investigated. The adsorption isotherm conformed to the Langmuir isotherm model and the maximum equilibrium ...

  • Innovation processes in moderately innovative countries: the competencies of knowledge brokers

    Successful innovation processes are strongly related to collaborations among actors in the business environment, including small and medium enterprises, local institutions, business associations, liaison offices, and technology transfer offices. Such collaborations are not well guided in moderately developed regions, where actors are not well supported by local institutions, and the level and ...

  • Analysis of different cost allocation methods in a collaborative transport setting

    In collaborative transport, dividing the total cost of the coalition between its different partners is a key issue. However, as each coalition has its own set of preferences and has partners with different characteristics, a cost allocation method suitable in all situations does not exist. In this paper, a set of cost allocation methods, some academic and some used in practice, are evaluated in ...

  • Equilibrium vs. optimal city size: evidence from Italian cities

    In this paper, the stylised assumption that one single ‘optimal’ city size exists for all cities – achieved when marginal location costs equal marginal location benefits – is abandoned, as well as the opposite view that each city operates on its own cost and production curves, defining a specific optimal size. Instead, this work maintains the comparability among cities and demonstrates that ...

  • Multinational R&D in China: differentiation and integration of global R&D networks

    Based on case studies of multinational R&D centres in China, this paper views the central task of corporate R&D globalisation as: differentiating R&D units to take advantage of location–specific resources and integrating R&D efforts in multiple locations to achieve the whole corporation's goals. Four differentiated R&D units are identified: the technology competence unit, the system competence ...

  • Assessing government–supported technology–based business incubators: evidence from China

    This study examines the effectiveness of government–supported incubator programmes in China. Findings highlight the importance of private–sector involvement in the incubators' governing body. Previous literature acknowledges the importance of government intervention in the entrepreneurial incubation process to overcome innovation market failure. However, factors that potentially influence the ...

  • Patterns of R&D internationalisation in developing countries: China as a case

    Some developing countries are emerging as nexuses in the globalisation of innovation activities, serving as the location for crucial R&D activities from developed multinational firms (DMFs), which are headquartered in developed countries, and spawning emerging multinational firms (EMFs), which are headquartered in developing countries and conduct some of their R&D in developed countries. This ...

  • Locate buried monitoring wells case study

    A Phase II Environmental Site Investigation was being conducted at a gasoline station in Fort Myers, Florida. In order to minimize costs, our client intended to use several existing on-site monitoring wells rather than installing new wells. However, five of the existing wells had been covered with asphalt and were no longer visible. GeoView was tasked with performing a shallow geophysical study ...

  • A consistent modelling methodology for secondary settling tanks: a reliable numerical method

    The consistent modelling methodology for secondary settling tanks (SSTs) leads to a partial differential equation (PDE) of nonlinear convection–diffusion type as a one-dimensional model for the solids concentration as a function of depth and time. This PDE includes a flux that depends discontinuously on spatial position modelling hindered settling and bulk flows, a singular source term ...

  • A forensic study to differentiate two dissolved gasoline plumes at adjoining service stations

    Three gasoline service stations are present at a highway intersection in central New Jersey. In the mid- to late- 1980s, service station “B” began to notice large discrepancies in their gasoline inventory. The USTs were removed in 1988 and a significant release was discovered. Separate-phase gasoline, as much as 1.5 feet (0.5 m) thick was present on the water table for about an area ...
