Innovative potential of the European Union’s member states in 2017

Purpose: The aim of this paper is to evaluate the innovative potential of the European Union’s countries in 2017. Design/Methodology/Approach: The authors have proposed their methodology of measuring the innovative potential of the EU Member States. Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) was used to rank and evaluate countries’ ability to innovate with respect to internal sources of innovativeness. Findings: The analysis confirms moderate innovative capacity of the EU countries. The classification of countries on the account of their innovative potential in 2017 reveals some similarities to ranking of Global Innovation Index (Input Sub-Index). Practical Implications: The paper proves that the most innovative countries in the light of the European Innovation Scoreboard display the highest ability to innovate. Therefore, internal resources of financial and human character were found to influence the overall level of innovativeness of member states. European countries should benefit from developing their innovative potential in terms of national resources. Originality/Value: Most researchers adopt input and output approach to innovativeness because it represents a sophisticated phenomenon. Due to shortage of studies measuring solely the innovative potential of economies, the paper will contribute to the development of literature.peer-reviewe

HAEMODYNAMIC RESPONSE DURING EXERCISE TESTING IN PATIENTS WITH CORONARY ARTERY DISEASE UNDERGOING A CARDIAC REHABILITATION PROGRAMME

Haemodynamic monitoring during exercise testing is seldom used during cardiac rehabilitation. The aim was to evaluate haemodynamic changes using the cardiac impedance method during exercise testing in patients after percutaneous coronary interventions and coronary artery bypass grafting during cardiac rehabilitation. Thirty (25 M; 5 F) patients were included in the programme. The group was divided according to ejection fraction (EF): low – below 50% normal – equal to or above 50%. The exercise test was performed simultaneously with a four-electrode impedance cardiogram before and after rehabilitation. ECG, blood pressure, thoracic impedance, first derivative dz/dt, stroke volume (SV) and cardiac output were recorded. Contractility index (Heather index – HI) and vascular peripheral resistance were calculated. The pattern of haemodynamic changes was normal in 24 patients. The deflection points for HI and SV trend patterns were observed among patients with low EF. The contractility index decreased 90 s before maximal exercise and after the next 30-60 s a deflection point was observed in SV curve trends. In 24 patients with normal EF the contractility index trends did not decrease and SV trends increased until the end of exercise or a deflection point was not noted. The deflection points of the contractility index and SV curves were observed before the clinical indications for exercise test termination appeared in patients with a low ejection fraction. Impedance cardiography may indicate the threshold of the workload during real-time exercise testing

Electromagnetically-induced transparency and light storing of a pair of pulses

Electromagnetically-induced transparency and light storing are studied in the case of a medium of atoms in a double Lambda configuration, both in terms of dark- and bright-state polatitons and atomic susceptibility. It is proven that the medium can be made transparent simultaneously for two pulses following their self-adjusting so that a condition for an adiabatic evolution has become fulfilled. Analytic formulas are given for the shapes and phases of the transmitted/stored pulses. The level of transparency can be regulated by adjusting the heights and phases of the control fields.Comment: text +6 figure

The evaluation of the quality of life in patients’ families during terminal malignancy at home

Wstęp. Okres terminalny to okres, gdy wyczerpały się możliwości dalszego przedłużania życia osoby przewlekle chorej bezpośrednim oddziaływaniem na przyczynę choroby, a chory wy-maga objęcia go opieką. Rodzina spotyka się wówczas z szeregiem problemów, w tym także ze zmianami swojej jakości życia. Problemy te rzadko poruszane w literaturze tematu skłoniły autorów do podjęcia badań własnych. Celem badań była ocena jakości życia członków rodzin pacjentów w terminalnym okresie choroby nowotworowej w warunkach domowych. Materiał i metody. Przebadano 60 osób – członków rodzin i jednocześnie opiekunów pacjentów będących w terminalnym okresie choroby nowotworowej, przebywających w domu. Sondaż został prze-prowadzony samodzielnie z uwzględnieniem wymagań etycznych tj. badanych poinformowano o anonimowości i celu przeprowadzonej ankiety. Pytania w nim zawarte dotyczyły sfery biopsycho-społecznej ankietowanych. Wyniki i wnioski. Jakość życia opiekunów chorych terminalnych obniża się. Pogorszenie jakości życia następuje zwłaszcza wtedy, gdy sprawowanie opieki spada na jedną osobę. Łączenie opieki z obowiązkami prowadzenia domu i pracy zawodowej, udzielanie wsparcia psychicznego choremu z jednoczesnym przeżywaniem perspektywy rozstania, rodzi uczucie przygnębienia i smutku. Także u chorego wywołuje to negatywne emocje np. drażliwość, gniew, depresję. Choroba w rodzinie wpływa na sytuację społeczno – zawodową badanych. 33,3% zmieniła całkowicie plany życiowe, co wiązało się z decyzją o zmniejszeniu czasu pracy i rezygnacji z dotychczasowego sposobu spędzania wolnego czasu. U respondentów, u których stwierdza się obniżenie jakości życia pomoc powinna obejmować sfery psychologiczno – bytowe rodziny. Sprawą podstawową byłoby podjęcie prób poprawy komunikacji i kontaktów wzajemnych z rodziną i poradnictwo psychologiczne. Równie ważna staje się opieka medyczna, nauka opiekunów zasad pielęgnacji, wiedza na temat możliwych nowych objawów chorobowych. Kolosalne znaczenie ma uświadomienie rodzinie, że choroba w fazie terminalnej jest nieodwracalną, nieuchronnie prowadzącą do śmierci.Introduction. Terminal malignancy is a period when the possibilities of prolonging a chronically ill patient’s life by means of affecting the cause of the disease are gone, and the patient is in need of care. Families encounter a lot of problems then, some of them related to the change in their quality of life. As these problems are infrequently undertaken in the literature of the field, the authors decided to conduct their own research. The purpose of it was to evaluate the quality of life of patients’ families during terminal malignancy at home. Materials and methods. 60 people were examined – they were all relatives and at the same time carers of terminal malignancy patients residing at their houses. The survey was conducted by authors them selves with a special consideration given to the ethical regulations, i.e. informing the interviewed about their anonymity and the purpose of the survey. The questions included in it were biological, psychological and social in nature. Results and conclusion. The quality of life is declining for carers of the terminally ill. The decline is the case especially when there is only one person to handle the related responsibilities. The care over the patient conjoined with running the household and professional life as well as supporting the patient while bearing the prospect of parting in mind are the sources of sadness and depression. Patients experience negative emotions as well, for instance irritation, anger, depression. The illness in a family affects the socio-professional situation of its members. 33,3% of them change their life plans entirely, which included decreasing the work frequency and giving up the previous leisure activities. The help offered to the respondents who experienced a decline in their quality of life should be psychological and existential. A basic issue here would be an attempt to make amends to the mutual communication and relations in the family as well as psychological counselling. Equally important is medical care as well as teaching the carers how to tend the sick person and what new symptoms may occur. Making it clear to the family that the terminal illness is irreversible and always leads to death is of utter importance

The quality of life depending on the patient’s condition

Artykuł dotyczy analizy jakości życia przy uwzględnieniu stany zdrowia. Autorzy definiują określenie jakości życia. Charakteryzują jakość życia z wykorzystaniem instrumentów subiektywnych, jak i obiektywnych.

They apply to both the sick and the healthy. The examples of generic scales include: WHOQOL- Bref, Sickness Impact Profile 136 (SIP), Short Form Health Survey (SF-36), Quality of Life Index (QOL, Quality of Life)

Combining short-term manipulative experiments with long-term palaeoecological investigations at high resolution to assess the response of Sphagnum peatlands to drought, fire and warming

International audienceNorthern hemisphere peatlands are substantial carbon stores. However, recent climate change and human impacts (e.g., drainage and atmospheric nutrient deposition) may trigger the emission of their stored carbon to the atmosphere. Biodiversity losses are also an important consequence of those changes. Therefore, there is a need to recognise these processes in space and time. Global change experiments are often conducted to improve our understanding of the potential responses of various ecosystems to global warming and drought. Most of the experiments carried out in peatlands are focused on carbon balance and nitrogen deposition. Nevertheless, it is still unclear how fast peatlands respond to temperature changes and water-table lowering in the continental climate setting. This is important because continental regions account for a significant proportion of all northern hemisphere peatlands. A combination of short-term and long-term approaches in a single research project is especially helpful because it facilitates the correct interpretation of experimental data. Here we describe the CLIMPEAT project-a manipulative field experiment in a Sphagnum-dominated peatland supported by a high-resolution multi-proxy palaeoecological study. The design of the field experiment (e.g., treatments), methodology and biogeographical setting are presented. We suggest it is beneficial to support field experiments with an investigation of past environmental changes in the studied ecosystem, as human impacts during the past 300 years have already caused substantial changes in ecosystem functioning which may condition the response in experimental studies

Synthesis of titanate nanostructures using amorphous precursor material and their adsorption/photocatalytic properties

This paper reports on a new and swift hydrothermal chemical route to prepare titanate nanostructures (TNS) avoiding the use of crystalline TiO2 as starting material. The synthesis approach uses a commercial solution of TiCl3 as titanium source to prepare an amorphous precursor, circumventing the use of hazardous chemical compounds. The influence of the reaction temperature and dwell autoclave time on the structure and morphology of the synthesised materials was studied. Homogeneous titanate nanotubes with a high length/diameter aspect ratio were synthesised at 160^{\circ}C and 24 h. A band gap of 3.06\pm0.03 eV was determined for the TNS samples prepared in these experimental conditions. This value is red shifted by 0.14 eV compared to the band gap value usually reported for the TiO2 anatase. Moreover, such samples show better adsorption capacity and photocatalytic performance on the dye rhodamine 6G (R6G) photodegradation process than TiO2 nanoparticles. A 98% reduction of the R6G concentration was achieved after 45 minutes of irradiation of a 10 ppm dye aqueous solution and 1 g/L of TNS catalyst.Comment: 29 pages, 10 figures, accepted for publication in Journal of Materials Scienc

Cachexia: pathophysiology and ghrelin liposomes for nose-to-brain delivery

Cachexia, a severe multifactorial condition that is underestimated and unrecognized in patients, is characterized by continuous muscle mass loss that leads to progressive functional impairment, while nutritional support cannot completely reverse this clinical condition. There is a strong need for more effective and targeted therapies for cachexia patients. There is a need for drugs that act on cachexia as a distinct and treatable condition to prevent or reverse excess catabolism and inflammation. Due to ghrelin properties, it has been studied in the cachexia and other treatments in a growing number of works. However, in the body, exogenous ghrelin is subject to very rapid degradation. In this context, the intranasal release of ghrelin-loaded liposomes to cross the blood-brain barrier and the release of the drug into the central nervous system may be a promising alternative to improve its bioavailability. The administration of nose-to-brain liposomes for the management of cachexia was addressed only in a limited number of published works. This review focuses on the discussion of the pathophysiology of cachexia, synthesis and physiological effects of ghrelin and the potential treatment of the diseased using ghrelin-loaded liposomes through the nose-to-brain route.Funded by PROSUP/Coordination of Superior Level Staff Improvement (CAPES), University of Sorocaba (UNISO), São Paulo Research Foundation (FAPESP/2014/50928-2), Brazil, granted to MVC, and by the Portuguese Science and Technology Foundation (FCT/MCT) and from European Funds (PRODER/COMPETE), co-financed by FEDER, under the Partnership Agreement PT2020 granted to EBS (UIDB/04469/2020 (strategic fund)info:eu-repo/semantics/publishedVersio
