Global sensitivity analysis of the SCOPE model : what drives simulated canopy - leaving sun - induced fluorescence?
2015
This study provides insight into the key variables that drive sun-induced chlorophyll fluorescence (SIF) emanating from vegetation canopies, based on a global sensitivity analysis (GSA) of the Soil-Canopy Observation of Photosynthesis and Energy (SCOPE) balance model. An updated version of the SCOPE model was used here (v1.53) which contains novel leaf physiological modules for determination of the steady state fluorescence yield: a photosynthesis model coupled with (a) submodels having empirically derived relationships, identified as TB12 for unstressed and TB12-D for drought conditions and (b) a mechanistic (MD12) submodel based on theoretical relationships. By inspecting Sobol's total or…
‘I changed my life’s course’ : The impact of the Helsingin Sanomat Foundation fellowship on the career path of a journalist
2017
This study focuses on the fellowship program of Helsingin Sanomat Foundation, which has sent a hundred mid-career journalists from Finland to study abroad at prominent universities. Based on two surveys, one on the fellows (n = 45) and one on a control group (n = 52), the article discusses the impact the fellowship education has on the journalists and their careers. The surveys are complemented with in-depth interviews of 10 fellow journalists. The results are discussed in the context of protean career concept, and they indicate that the fellowship period has a notable positive impact on the career of an individual journalist, but a contradictory impact on the journalist’s home organizatio…

Neuronal cell cultures: A tool for investigations in developmental neurobiology
1992
The aim of this review is to describe environmental requirements for survival of neuronal cells in culture, and secondly to survey the complex interplay between hormones, neurotrophic factors, transport- and extracellular matrix- proteins, which characterize the developmental program of differentiating neurons. An overall reconsideration of the literature in this vast field is above the limits of the present paper; since progress and refinement in the techniques of neuronal cell cultures have paralleled the advancement in Developmental Neurobiology, we will run instead through the main steps which form the conceptual framework of neuronal cell cultures. © 1992 Plenum Publishing Corporation.
Venezuela's humanitarian crisis, resurgence of vector-borne diseases, and implications for spillover in the region
2019
In the past 5–10 years, Venezuela has faced a severe economic crisis, precipitated by political instability and declining oil revenue. Public health provision has been affected particularly. In this Review, we assess the impact of Venezuela's health-care crisis on vector-borne diseases, and the spillover into neighbouring countries. Between 2000 and 2015, Venezuela witnessed a 359% increase in malaria cases, followed by a 71% increase in 2017 (411 586 cases) compared with 2016 (240 613). Neighbouring countries, such as Brazil, have reported an escalating trend of imported malaria cases from Venezuela, from 1538 in 2014 to 3129 in 2017. In Venezuela, active Chagas disease transmission has be…
Teaching Green Analytical and Synthesis Chemistry: Performing Laboratory Experiments in a Greener Way
2019
Our future challenges in resource, environmental and societal sustainability demand efficient and benign-by-design scientific technologies for working with chemical processes and products. In this chapter, we have considered the major aspects of green analytical and synthetic chemistry as a new paradigm and its integration with higher education course curriculum. Teaching green analytical chemistry must be focused on analytical parameters and practices more than on the incorporation of the so-called green parameters to the basic analytical properties. Thus accuracy, representativeness, traceability, sensitivity and selectivity in the renewed paradigmatic chemistry have been complemented and…

Green Analytical Chemistry
2008
We discuss the origins and the fundamentals of Green Analytical Chemistry (GAC), based on the literature published about clean, environmentally-friendly or GAC methods. We pay special attention to the strategies and the tools available to make sample-pretreatment and analytical methods greener. We consider that the main principles are to replace toxic reagents, to miniaturize and to automate methods, making it possible to reduce dramatically the amounts of reagents consumed and wastes generated, so reducing or avoiding side effects of analytical methods. We also consider on-line decontamination or passivation of wastes to be of special interest in making analytical chemistry sustainable.
