The formation of R&D networks: The case of Greece

The concept of an NIS provides a tool for analyzing country specificities in the innovation process in a globalised economy, as well as a guide for policy formulation. It highlights interactions and interfaces between various actors and the workings of the system as a whole rather than the performance of its individual components. Under a social network analysis perspective, a national innovation system can be seen as a network of actors (firms, academic institutions, research centers), that are linked to each other. We employ social network analysis and graph theory to describe the topology, structural properties and evolution of the network of R&D collaborations among firms, academic institutions in Greece. Our results indicate the formation of an “oligarchic” network, built around a few highly connected central actors, which are the leading and most innovative Greek firms and the most well reputed academic institutions and research centres, and which constitute the core of the network. Furthermore, national R&D policy is highlighted as it brings closer together firms and research institutions, acting as a catalyst for the creation of stable ties.
Measurement of eddy-current loss coefficient P/sub EC-R/, derating of single-phase transformers, and comparison with K-factor approach

A power amplifier is used to supply sinusoidal currents of different frequencies for measuring eddy-current losses of a 25 kVA single-phase transformer under short-circuit condition. Measured data show that eddy-current loss is a linear function of frequency with power of 2 and the eddy-current loss coefficient P/sub EC-Rlinear/ is computed. New measurement techniques are applied to determine the derating of single-phase transformers with full-wave diode and thyristor rectifier loads. The derating of transformers has been defined such that for the (apparent, real) power transfer of a transformer the total losses are identical to the rated losses at rated temperature. A relation between apparent power, derating and K-factor is given taking into account iron-core and stray-power losses. Measured derating values are compared with computed results based on the eddy-current losses, iron-core losses, stray-power losses, and K-factors. The eddy-current loss coefficient P/sub EC-Rnonlinear/ is computed from harmonics caused by diode/thyristor bridge loads.
Effectiveness of prophylactic vitamin C supplementation in the prevention of complex regional pain syndrome after distal end radius fractures in the aging population

Background/purpose Vitamin C has been proposed to prevent the incidence of complex regional pain syndrome, but the results are conflicting. We evaluated the effectiveness of vitamin C in the prevention of complex regional pain syndrome-1 after distal end radius fractures in the aging population. Methods This was a prospective, randomized study. Patients treated with either conservative or surgical management for distal end radius fracture received Vitamin C (500 mg/day) plus standard therapy or standard therapy alone for a period of 3 months. The presence of complex regional pain syndrome-1 was assessed with Budapest criteria. Results The complex regional pain syndrome-I occurred in 11.3% in Vitamin C plus Standard in compared to 26% in Standard therapy alone. Vitamin C was significantly associated with a reduction in the likelihood of exhibiting complex regional pain syndrome-1. Conclusion Vitamin C (500 mg/day) supplementation was effective and associated with a lower occurrence of acute complex regional pain syndrome-1. It can be a promising prophylactic option for the prevention of complex regional pain syndrome-1 after distal end radius fracture.
Schadet die Flexibilisierung des Arbeitsmarktes der Innovation

Deregulierung von Arbeitsmarkten und Lohnzuruckhaltung haben signifikant niedrigere Wachstumsraten der Arbeitsproduktivitat zur Folge. Dieser Beitrag diskutiert theoretische Argumente, warum "starre" Arbeitsmarkte fur Innovationen nutzlich sein konnen. Empirische Studien fundieren diese Argumente. Das Argument, dass grosere Fluktuationen im Personalbestand schadlich sind fur Innovationen und Lernprozesse, gilt vor allem fur Betriebe mit einem "routinemasigen" Innovationsmodell. Diese Betriebe sind stark abhangig von historisch akkumulierter Kenntnis, wovon viel personengebunden und schlecht dokumentiert ist ("tacit knowledge"). "Garage Business"-Betriebe wie etwa in Sillicon Valley brauchen mehr allgemein verfugbare Kenntnisse und haben damit viel weniger Probleme mit haufigerem Personalwechsel. Es ist interessant festzustellen, dass sich das Wachstum des Bruttoinlandsprodukts zwischen angelsachsischen Landern (mit flexiblen Arbeitsmarkten) und korporatistischen Landern (mit relativ rigiden Arbeitsmarkten) nur geringfugig unterscheidet. Auserdem gibt es Anlass, die Behauptung zu bezweifeln, dass "flexible" Lander niedrigere Arbeitslosenzahlen hatten.
Implementation and Direct Accessing of Android Authority Application in Smart Phones

Now a day in mobile or smart phone internet access is very simple. In smart phone there are lots of applications available in android market. But in recent smart phone there is no new existing system or tag so that user can update with upcoming new applications in android market. To share new applications, user must have gone through the website of android authority by browser and then user can share it. But android authority URL is accessible by smart phone time consuming and it is not quite flexible to open browser. Here first write URL of the site and then open website. So user cannot go through with whole website using smart phone because user has to install various tools to open a website on smart phone. So this paper addresses the solution of above problem. Here new existing system of android authority has been implemented in which new tag of above website is defined and user can directly access it.
A case study of fuel savings through optimisation of MSW transportation routes

Purpose – The high costs of collection and transportation of municipal solid waste (MSW) on the overall waste management budget (sometimes more than 75 per cent) makes it an issue to be urgently addressed for improvement. The paper aims to focus on the optimisation of routing networks for waste collection/transportation.Design/methodology/approach – The paper proposes herein the application of geographic information system (GIS) 3D route modelling for waste collection/transportation to optimise the route according to the minimum fuel consumption criterion to different municipalities of the island of Santo Antao of Cape Verde.Findings – The optimisation for the lowest fuel consumption yields 52 per cent savings in fuel, when compared to that for the shortest distance, even travelling a 34 percent longer distance, which shows the importance of considering simultaneously the relief of the territory and the lowest fuel consumption criterion when optimising vehicle routes.Practical implications – With such a s.
Social Positioning Analysis as a Qualitative Methodology to Study Identity Construction in People Diagnosed With Severe Mental Illnesses

Severe mental illnesses (SMI) in general, and schizophrenia in particular, have been characterized as alterations of the experience of self and identity. When first diagnosed with SMI, the subjective experiences and specific narrative challenges faced by this population are particularly important. Therefore, qualitative approaches which allow to analyze these subjective experiences should be developed. This article presents in detail a specific method, called Social Positioning Analysis, which makes the complexity of narratives and life stories with multiple turning points understandable. To develop this methodological proposal, it has been taken into account the performative aspects of social interaction in which narratives are constructed. The methodology has previously been used in other health contexts and is innovative in the field of mental health. Linguistic criteria, definitions, and multiple examples are included to facilitate its application, as well as some reflections about its potential and possible benefits.
Polymeric Materials for Hemostatic Wound Healing

Hemorrhage is one of the greatest threats to life on the battlefield, accounting for 50% of total deaths. Nearly 86% of combat deaths occur within the first 30 min after wounding. While external wound injuries can be treated mostly using visual inspection, abdominal or internal hemorrhages are more challenging to treat with regular hemostatic dressings because of deep wounds and points of injury that cannot be located properly. The need to treat trauma wounds from limbs, abdomen, liver, stomach, colon, spleen, arterial, venous, and/or parenchymal hemorrhage accompanied by severe bleeding requires an immediate solution that the first responders can apply to reduce rapid exsanguinations from external wounds, including in military operations. This necessitates the development of a unique, easy-to-use, FDA-approved hemostatic treatment that can deliver the agent in less than 30 s and stop bleeding within the first 1 to 2 min at the point of injury without application of manual pressure on the wounded area.
A time-series ecological study protocol to analyze trends of incidence, mortality, lethality of COVID-19 in Brazil

Introduction: Since the first case of COVID-19 was confirmed in February 2020, Brazil has reported more than 20 million cases and more than 600,000 deaths on October 31, 2021. The behavior of the pandemic was also different in the various regions of the country, from those with less economic development to those with greater economic development, such as the state of São Paulo. Objective: to describe step-by-step time series for analyzing trends in mortality, lethality and incidence of COVID-19 in Brazil. Methods: a protocol for an ecological study of time series, covering the 26 states and the federal district (Brasilia). Results: The descriptions have the potential to provide information for the government and society in decision-making, about knowledge and conduct, clinical, epidemiological and research investments in health care for the Brazilian people. It is focused on fully understanding the spread of SARS-COV-2 infection in the Brazilian territory, and developing a database for public and universal access for comparative studies between countries and continents. Conclusion: database built from ecological studies are essential for a full understanding of the virus behavior, its transmissibility, lethality and mortality, and a repository for data that’s been collected and integrated from multiple sources. It is a relevant tool for the search of information and decision-making in global health.
Development of a Postprocessing Methodology for Studying Thermal Stratification in an HCCI Engine

Naturally occurring thermal stratification significantly impacts the characteristics of homogeneous charge compression ignition (HCCI) combustion. The in-cylinder gas temperature distributions prior to combustion dictate the ignition phasing, burn rates, combustion efficiency, and unburned hydrocarbon and CO emissions associated with HCCI operation. Characterizing the gas temperature fields in an HCCI engine and correlating them to HCCI burn rates is a prerequisite for developing strategies to expand the HCCI operating range. To study the development of thermal stratification in more detail, a new analysis methodology for postprocessing experimental HCCI engine data is proposed. This analysis tool uses the autoignition integral in the context of the mass fraction burned curve to infer information about the distribution of temperature that exists in the cylinder prior to combustion. An assumption is made about the shape of the charge temperature profiles of the unburned gas during compression and after combustion starts elsewhere in the cylinder. Second, it is assumed that chemical reaction rates proceed very rapidly in comparison to the staggering of ignition phasing from thermal stratification. The autoignition integral is then coupled to the mass fraction burned curve to produce temperature-mass distributions that are representative of a particular combustion event. Due to the computational efficiency associated with this zero-dimensional calculation, a large number of zones can be simulated at very little computational expense. The temperature-mass distributions are then studied over a coolant temperature sweep. The results show that very small changes to compression heat transfer can shift the distribution of mass and temperature in the cylinder enough to significantly affect HCCI burn rates and emissions.
Experimental and numerical investigation into useful wrinkling during aluminium alloy internal high-pressure forming

Abstract Internal high-pressure forming is a process for manufacturing lightweight components, especially automotive parts, with advantages of lower cost and weight reduction, better structural integrity and increased strength and stiffness over the conventional stamping process. One of the typical failure modes, including wrinkling, buckling and splitting, will occur through an unreasonable combination of the control parameters: the internal pressure and the axial punch feeding. In most previous papers, wrinkling is considered to be a failure mode. However, not all wrinkles are defects. The collection of materials in an expanding area by the formation of wrinkles is an alternative method for obtaining a preformed shape in the hydroforming die. In this case, the key point is to obtain ‘useful’ wrinkles instead of ‘bad’ wrinkles. In this paper, an investigation will be conducted on how to control the shape of the wrinkle waves and its effect on the thickness distribution after hydroforming by using finite element simulation. LS-DYNA finite element software is used in this paper. An experiment has been carried out and the results obtained from experiment and simulation are in good agreement.
Porcine Deltacoronavirus Utilizes Sialic Acid as an Attachment Receptor and Trypsin Can Influence the Binding Activity

Porcine deltacoronavirus (PDCoV) is a novel coronavirus that causes diarrhea in nursing piglets. Studies showed that PDCoV uses porcine aminopeptidase N (pAPN) as an entry receptor, but the infection of pAPN-knockout cells or pigs with PDCoV revealed that pAPN might be not a critical functional receptor, implying there exists an unidentified receptor involved in PDCoV infection. Herein, we report that sialic acid (SA) can act as an attachment receptor for PDCoV invasion and facilitate its infection. We first demonstrated that the carbohydrates destroyed on the cell membrane using NaIO4 can alleviate the susceptibility of cells to PDCoV. Further study showed that the removal of SA, a typical cell-surface carbohydrate, could influence the PDCoV infectivity to the cells significantly, suggesting that SA was involved in the infection. The results of plaque assay and Western blotting revealed that SA promoted PDCoV infection by increasing the number of viruses binding to SA on the cell surface during the adsorption phase, which was also confirmed by atomic force microscopy at the microscopic level. In in vivo experiments, we found that the distribution levels of PDCoV and SA were closely relevant in the swine intestine, which contains huge amount of trypsin. We further confirmed that SA-binding capacity to PDCoV is related to the pre-treatment of PDCoV with trypsin. In conclusion, SA is a novel attachment receptor for PDCoV infection to enhance its attachment to cells, which is dependent on the pre-treatment of trypsin on PDCoV. This study paves the way for dissecting the mechanisms of PDCoV–host interactions and provides new strategies to control PDCoV infection.
Identifying Targets for Interventions to Increase Earplug Use in Noisy Recreational Settings: A Qualitative Interview Study

Earplugs can reduce the risk of hearing loss and tinnitus. However, earplug use during noisy recreational activities is uncommon, and methods for increasing uptake and regular use have had limited efficacy. The aim of the present study was to examine barriers and enablers of ever-performers (e.g., people who have used earplugs) and never-performers (e.g., people who have not used earplugs) to identify targets to inform the content of interventions to increase uptake and regular use of earplugs in recreational settings. The Capabilities, Opportunities, and Motivations model of Behaviour (COM-B) informed the outline for 20 semi-structured telephone interviews (ever-performers, N = 8, age range = 20–45 years; never-performers, N = 12; age range = 20–50 years). Thematic analysis was used to identify barriers and enablers to earplug use, which were mapped onto the Theoretical Domains Framework (TDF). Six key domains of the TDF were identified. Ever-performers described being more exposed to ‘social influences’ (e.g., facilitators such as friends/peers) and were more positive than never-performers concerning ‘beliefs about consequences’ (e.g., earplug protection outweighs any negative effects on listening/communication). Involvement of ‘emotion’ (e.g., fear of losing ability to listen to music) and ‘reinforcement’ tactics (e.g., creating habits/routines) were discussed by ever-performers, but were not mentioned by never-performers. Both groups reported lack of ‘environmental context and resources’ (e.g., prompts and cues), and their own ‘memory, attention, and decision processes’ (e.g., deciding when to use earplugs) as barriers to earplug use. The present research identifies the variables that would need to change in order to increase earplug uptake and use in recreational settings among ever-performers and never-performers. Further work is required to translate these findings into testable interventions by selecting appropriate intervention functions (e.g., modelling), policy categories (e.g., communication/marketing), behaviour change techniques (e.g., demonstration of behaviour), and mode of delivery (e.g., face-to-face).
MEASURING A RELATIONSHIP MANAGEMENT CAPABILITY'S PERFORMANCE OUTCOMES

Although 'capability' is a word used with increasing frequency in both the management and marketing literature, few authors have contributed to the debate on how a capability that has the capacity for renewal might be constructed. The purpose of this research was to validate a theoretical representation of a relationship management capability, and then examine its causal association with multiple measures of performance. A relationship management capability was identified as a higher-order capability, combining both functional and integrative capabilities. The contributions of the second order constructs comprising a relationship management capability (Relationship Infrastructure Capability, Relationship Learning Capability and Relationship Management Application) to the variance in positional advantage, customer performance, market performance and financial performance were tested in major, organizational, customer relationships through a quantitative survey. Confirmatory factor analysis established the robustness of the theoretical model with the removal of ‘relationship experience’, a factor contributing to the definition of Relationship Infrastructure Capability. The results of the structural equation models incorporating relationship management capability and the various performance measures provided evidence that Relationship Management Capability has a direct, significant, contribution to each measure of performance.
THERMODYNAMIC STUDY OF ATMOSPHERIC CORROSION SEASONAL KINETIC, BASED ON SUN PHOTOMETER DATA

Original scientific paper The atmospheric corrosion is a mechanical, technological, economic as well as an ecological problem, due to the enormous losses in corroded vessels material and machine material due to enhanced content of corroded material pollutants in environment. The results of the thermodynamic diagnostic study are given in this paper of the limited step in the water vapor corrosion kinetic based on the monitoring data for the seasonal water vapor pressure measured daily in Timisoara, by 2011, from March to December. Based on the seasonal values of the measured data, the seasonal diffusion rate constants the activation energies of the first chemical corrosion step are determined. The calculated seasonal water vapor chemical surface polarizations relative to the values of equilibrium entropies and also of the condensed water vapor on the solid surfaces are compared with the literature data of the possible products of chemical processes. The thermodynamic diagnostic study of the limited successive relaxation step in overall corrosion kinetic is carried out, based on the comparison of the molar water vapor couple relaxation work. The depolarization work is proportional to the depolarization rate constants of reactants and products activated successively in couple with water vapor concentrations depolarization energy, in the same time period: the electrochemical relaxation for the achievement of oxygen and hydrogen equilibrium in the seasonal activated corrosion cell, hydrogen depolarization energy and oxygen striping indicators standard potential. Data used to calculate the water vapor pressure in atmosphere are based on measurements accomplished by a sun photometer located at the Politechnica University of Timisoara, Romania (45,74 °N; 21,22 °E). The extraction of water vapor amount from sun photometer capacity relies on a measurement in the region of water vapor absorption at 940 nm. In order to apply the empirical models, the temperature, barometric pressure and humidity content have been taken from a weather station. One found that the experimental values of water vapor pressure, obtained using the sun photometer, are comparable with four other methods, and within, the experimental variations is characterized by a relative error of 2 %.
