    Large part of the project manager's work can be described in terms of retrieving, processing, analysing and synthesizing various types of data from different sources. The types of information become more and more diverse (including participants, task and financial details, and dates) and data volumes continue to increase, especially for large international collaborations. In this paper we explore the possibility of using the python programming language as a tool for retrieving and processing data for some project management tasks. python is a general-purpose programming language with a very rich set of libraries. In recent years python experienced explosive growth leading to development of several libraries that help to efficiently solve many data related tasks without very deep knowledge of programming in general and python in particular. In this paper we present some of the core python libraries that can be used to solve some typical project management tasks and demonstrate several real-world applications using a HORIZON 2020 type European project and as example.</p

    Maximal nowhere dense PP-sets in basically disconnected spaces and FF-spaces

    summary:In [5] the following question was put: are there any maximal n.d. sets in ω\omega^*? Already in [9] the negative answer (under {\bf MA}) to this question was obtained. Moreover, in [9] it was shown that no PP-set can be maximal n.d. In the present paper the notion of a maximal n.d. PP-set is introduced and it is proved that under {\bf CH} there is no such a set in ω\omega^*. The main results are Theorem 1.10 and especially Theorem 2.7(ii) (with Example in Section 3) in which the problem of the existence of maximal n.d. PP-sets in basically disconnected compact spaces with rich families of n.d. PP-sets is actually solved

    Cognitive impairment in primary and repeated hemorrhagic stroke and their correction with verapamil

    Get PDF
    The article is devoted the actual problem of modern medicine – pathogenesis and treatment of hemorrhagic stroke. In order to analyze the influence of Verapamil in preventing cognitive disorders under stroke a local hemorrhagic stroke in 60 rats was simulated there. Assessment of the cognitive function was performed by the Buresh method. We found out that rats after stroke were observed to show memory disturbances. Under stroke and after Verapamil injections the rats had a gradual decrease of disorders in primary and repeated intracerebral hemorrhage. These data suggest inhibition of calcium-dependent neurodegenerative processes in the rat cortex and cognitive disorders under Verapamil injections after stroke

    The stabilization of unstable detonation waves for the mixture of nitromethane/methanol

    Mass velocity profiles of detonation waves in mixtures of nitromethane with acetone and methanol with added diethylenetriamine sensitizer were measured using a VISAR laser interferometer. It was found that even small, about 1%, concentrations of acetone and methanol, inert diluents, led to instability of the one-dimensional detonation front in nitromethane. The results of the experiment show that the use of the sensitizer is an effective method of flow stabilization and if the concentration of the inert diluent does not exceed 10%, the detonation front becomes stable with the addition of 1% diethylenetriamine. At a higher diluent concentration, the sensitizer does not suppress the instability but decreases the oscillation amplitude by several times. The addition of diethylenetriamine to the mixture has been found to increase the detonation velocity

    On the Damping Time Scale of EVP Sea Ice Dynamics

    Get PDF
    We propose to make the damping time scale, which governs the decay of pseudo-elastic waves in the Elastic Viscous Plastic (EVP) sea-ice solvers, independent of the external time step and large enough to warrant numerical stability for a moderate number of internal time steps. A necessary condition is that the forcing on sea ice varies slowly on the damping time scale, in which case an EVP solution may still approach a Viscous Plastic one, but on a time scale longer than a single external time step. In this case, the EVP method becomes very close to the recently proposed modified EVP (mEVP) method in terms of stability and simulated behavior. In a simple test case dealing with sea ice breaking under the forcing of a moving cyclone, the EVP method with an enlarged damping time scale can simulate linear kinematic features which are very similar to those from the traditional EVP implementation, although a much smaller number of internal time steps is used. There is more difference in sea-ice thickness and linear kinematic features simulated in a realistic Arctic configuration between using the traditional and our suggested choices of EVP damping time scales, but it is minor considering model uncertainties associated with choices of many other parameters in sea-ice models

    Modified halocline water over the Laptev Sea continental margin : historical data analysis

    Get PDF
    Historical hydrographic data (1940s–2010) show a distinct cross-slope difference of the lower halocline water (LHW) over the Laptev Sea continental margins. Over the slope, the LHW is on average warmer and saltier by 0.2°C and 0.5 psu, respectively, relative to the off-slope LHW. The LHW temperature time series constructed from the on-slope historical records are related to the temperature of the Atlantic Water (AW) boundary current transporting warm water from the North Atlantic Ocean. In contrast, the on-slope LHW salinity is linked to the sea ice and wind forcing over the potential upstream source region in the Barents and northern Kara Seas, as also indicated by hydrodynamic model results. Over the Laptev Sea continental margin, saltier LHW favors weaker salinity stratification that, in turn, contributes to enhanced vertical mixing with underlying AW

    Influence of psychophysiological features of the 3-d course students on their training at the department of pathological physiology SE "DMA".

    Get PDF
    The article presents the results of the individual psychophysiological features analysis of the 3-d course students of the Dentistry Faculty, who have completed studying pathological physiology. The obtained data were compared with the results of the complex exam and the results of the licensing exam STEP-1. As a result, it was found that the psychophysiological indicators of students affect on learning performance. The main psychological differences between successful and unsuccessful students are in the intellectual and emotional-will spheres. Therefore, conducting psychophysiological testing among students and familiarizing them with the results obtained makes it possible for future doctors to take into account their personal and psychophysiological characteristics not only during the training period, but also in their professional activities. Such information, on the one hand, may induce many students to work on themselves, and on the other - not to fall into illusions. Further research in this direction and carrying out correlations of the obtained results will allow to find and eliminate the causes of unsatisfactory students’ studying. Work in this direction will contribute to the development of fundamentally new teaching methods in accordance with the requirements of time and scientific-technical progress

    Ocean Model Formulation Influences Transient Climate Response

    Get PDF
    The transient climate response (TCR) is 20% higher in the Alfred Wegener Institute Climate Model (AWI-CM) compared to the Max Planck Institute Earth System Model (MPI-ESM) whereas the equilibrium climate sensitivity (ECS) is by up to 10% higher in AWI-CM. These results are largely independent of the two considered model resolutions for each model. The two coupled CMIP6 models share the same atmosphere-land component ECHAM6.3 developed at the Max Planck Institute for Meteorology (MPI-M). However, ECHAM6.3 is coupled to two different ocean models, namely the MPIOM sea ice-ocean model developed at MPI-M and the FESOM sea ice-ocean model developed at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI). A reason for the different TCR is related to ocean heat uptake in response to greenhouse gas forcing. Specifically, AWI-CM simulations show stronger surface heating than MPI-ESM simulations while the latter accumulate more heat in the deeper ocean. The vertically integrated ocean heat content is increasing slower in AWI-CM model configurations compared to MPI-ESM model configurations in the high latitudes. Weaker vertical mixing in AWI-CM model configurations compared to MPI-ESM model configurations seems to be key for these differences. The strongest difference in vertical ocean mixing occurs inside the Weddell and Ross Gyres and the northern North Atlantic. Over the North Atlantic, these differences materialize in a lack of a warming hole in AWI-CM model configurations and the presence of a warming hole in MPI-ESM model configurations. All these differences occur largely independent of the considered model resolutions
