    Although the use and management of ecosystem services (ES) resources and the promotionof their provision are a standard and necessary part of spatial planning tools and documents, a directimplementation of this concept is exceptional. Researchers and entire projects have so far focusedmainly on identification of ecosystem services and their resources in urban environment, or on theanalysis of their occurrence in spatial planning documents. That was the goal of our research as well.Spatial planning documents, systematically and methodically re-defined using ecosystem services,are what is still lacking. Our article presents the results of the analysis of the use of ecosystem servicesin spatial plans of five cities, regional centers in the Czech Republic. We used a text evaluationmethodology focused on the explicit and implicit expression of ecosystem services. We analyzed theoverall approach to the creation of spatial plans. In addition to the spatial plans, we also analyzedtheir assignments (SPA). We found that the current spatial planning methodology does not work withthe ecosystem services approach (ESA) systemically. It focuses mainly on ES resources and implicitlyenvisages their provision. SPAs are a more flexible and effective tool for enforcing ESA in spatialplanning than the lengthy legislative process. However, this presupposes greater knowledge of SPAamong the public and decision makers.O

    Stakeholders' Perception of the Impact of the Declaration of New Protected Areas on the Development of the Regions Concerned, Case Study: Czech Republic

    Floodplain forests at the confluence of the rivers Dyje and Morava (in the southeastern tip of the Czech Republic) are completely unique ecosystems in terms of area and ecology. For many years, there has been an effort by the state's nature protection officials to declare the area as a Protected Landscape Area. This effort is met by the resistance of foresters and other local stakeholders. The study focuses on the identification of stakeholders' comments and objections to the planned declaration of the Soutok PLA and the comparison between the objections raised and the attitudes of stakeholders from existing PLAs. Using the content analysis of 247 paper documents, the first part of the study determines the negative arguments that are subsequently verified in the second part on the basis of 17 semistructured standardized interviews and interview surveys of 200 respondents. The analysis of the interviews and surveys was based on the grounded theory method. The theoretical sampling and snowball techniques were used to recruit the respondents. The interviews and surveys showed that most concerns over restrictions established by the conservation status are unnecessary since experience showed that they are either not registered or not established by the PLA status, and their application is provided by other legislative standards.O

    Outer membrane protein functions as integrator of protein import and DNA inheritance in mitochondria

    Get PDF
    Trypanosomatids are one of the earliest diverging eukaryotes that have fully functional mitochondria. pATOM36 is a trypanosomatid-specific essential mitochondrial outer membrane protein that has been implicated in protein import. Changes in the mitochondrial proteome induced by ablation of pATOM36 and in vitro assays show that pATOM36 is required for the assembly of the archaic translocase of the outer membrane (ATOM), the functional analog of the TOM complex in other organisms. Reciprocal pull-down experiments and immunofluorescence analyses demonstrate that a fraction of pATOM36 interacts and colocalizes with TAC65, a previously uncharacterized essential component of the tripartite attachment complex (TAC). The TAC links the single-unit mitochondrial genome to the basal body of the flagellum and mediates the segregation of the replicated mitochondrial genomes. RNAi experiments show that pATOM36, in line with its dual localization, is not only essential for ATOM complex assembly but also for segregation of the replicated mitochondrial genomes. However, the two functions are distinct, as a truncated version of pATOM36 lacking the 75 C-terminal amino acids can rescue kinetoplast DNA missegregation but not the lack of ATOM complex assembly. Thus, pATOM36 has a dual function and integrates mitochondrial protein import with mitochondrial DNA inheritance

    Convergence properties of η3π\eta\to 3\pi decays in chiral perturbation theory

    Theoretical efforts to describe and explain the η3π\eta\to 3\pi decays reach far back in time. Even today, the convergence of the decay widths and some of the Dalitz plot parameters seems problematic in low energy QCD. In the framework of resummed CHPT, we explore the question of compatibility of experimental data with a reasonable convergence of a carefully defined chiral series, where NNLO remainders are assumed to be small. By treating the uncertainties in the higher orders statistically, we numerically generate a large set of theoretical predictions, which are then confronted with experimental information. In the case of the decay widths, the experimental values can be reconstructed for a reasonable range of the free parameters and thus no tension is observed, in spite of what some of the traditional calculations suggest. The Dalitz plot parameters aa and dd can be described very well too. When the parameters bb and α\alpha are concerned, we find a mild tension for the whole range of the free parameters, at less than 2σ\sigma C.L. This can be interpreted in two ways - either some of the higher order corrections are indeed unexpectedly large or there is a specific configuration of the remainders, which is, however, not completely improbable. Also, the distribution of the theoretical uncertainties is found to be significantly non-gaussian, so the consistency cannot be simply judged by the 1σ\sigma error bars.Comment: 57 pages, 5 figure

    An investigation of thermoelectric generators used as energy harvesters in a water consumption meter application

    Get PDF
    In this study, we present the results of measuring the performance of selected Peltier cells such as thermoelectric Peltier cooler modules (TEC), thermoelectric micro-Peltier cooler modules (TES), and thermoelectric Seebeck generator modules (TEG). The achieved results are presented in the form of graphs of powering system output voltage or power efficiency functions of the load impedance. Moreover, a technical solution is also presented that consists of designing a water consumption power supply system, using a renewable energy source in the form of a Peltier cell. The developed measuring system does not require additional batteries or an external power source. The energy needed to power the system was obtained from the temperature difference between two sides of a thermoelectric cell, caused by the measured medium which was flowing in a copper water pipe. All achieved results were investigated for the temperature difference from 1 to 10 K in relation to the ambient temperature.Web of Science1413art. no. 376

    The Concussion Recognition Tool 5th Edition (CRT5): Background and rationale

    Get PDF
    The Concussion Recognition Tool 5 (CRT5) is the most recent revision of the Pocket Sport Concussion Assessment Tool 2 that was initially introduced by the Concussion in Sport Group in 2005. The CRT5 is designed to assist non-medically trained individuals to recognise the signs and symptoms of possible sport-related concussion and provides guidance for removing an athlete from play/sport and to seek medical attention. This paper presents the development of the CRT5 and highlights the differences between the CRT5 and prior versions of the instrument

    Consensus statement on concussion in sport—the 5 th international conference on concussion in sport held in Berlin, October 2016

    Get PDF
    The 2017 Concussion in Sport Group (CISG) consensus statement is designed to build on the principles outlined in the previous statements1–4 and to develop further conceptual understanding of sport-related concussion (SRC) using an expert consensus-based approach. This document is developed for physicians and healthcare providers who are involved in athlete care, whether at a recreational, elite or professional level. While agreement exists on the principal messages conveyed by this document, the authors acknowledge that the science of SRC is evolving and therefore individual management and return-to-play decisions remain in the realm of clinical judgement. This consensus document reflects the current state of knowledge and will need to be modified as new knowledge develops. It provides an overview of issues that may be of importance to healthcare providers involved in the management of SRC. This paper should be read in conjunction with the systematic reviews and methodology paper that accompany it. First and foremost, this document is intended to guide clinical practice; however, the authors feel that it can also help form the agenda for future research relevant to SRC by identifying knowledge gaps
