Are deep eutectic solvents useful in chromatography? A short review.
2021
A literature update has been done concerning Deep Eutectic Solvents (DES) use in chromatography applications. The literature survey was based on the period from 2010 till 2020 and manuscripts reported in the data bases Web of Science and Scopus. The use of DES as mobile phase and mobile phase additives, stationary phases and solid phase modifiers and the use of DES as reaction solvents for chromatography use, were evaluated. Emphasis was placed on the differentiation of DES and Ionic Liquids (ILs) and the advanced green characteristics of the new solvents as compared with traditional organic solvents and ILs with a look into the drawbacks and future perspectives in the field of separation m…
Literature survey of the on-line preconcentration in flow-injection atomic spectrometric analysis
1992
The literature on the use of “on-line” preconcentration in flow injection atomic spectrometric analysis is reviewed, taking into account its application both in flame and electrothermal atomic absorption methods as well as in plasma emission spectrometry. The basis of the different preconcentration approaches, such as liquid-liquid extraction, column preconcentration and “on-line” precipitation are discussed. The literature survey reveals the analytical performance of the developed methodologies.
Project Management Information Systems (PMISs): A Statistical-Based Analysis for the Evaluation of Software Packages Features
2021
Project Managers (PMs) working in competitive markets are finding Project Management Information Systems (PMISs) useful for planning, organizing and controlling projects of varying complexity. A wide variety of PMIS software is available, suitable for projects differing in scope and user needs. This paper identifies the most useful features found in PMISs. An extensive literature review and analysis of commercial software is made to identify the main features of PMISs. Afterwards, the list is reduced by a panel of project management experts, and a statistical analysis is performed on data acquired by means of two different surveys. The relative importance of listed features is properly comp…
Discovering the Cohesion of a Volleyball Team and Finding the Right Leader of the Group
2018
Abstract The main focus of the research was to discover the cohesion of our team and to find the leader of our volleyball group. The research sample was composed of 12 players with aged between 10 and 12 years old that play for CSM Bucharest at mini-volleyball level. The main research methods used was the sociometric survey method which aimed to find the elections and rejections in our group and to discover the hierarchy of every player in the team. The results showed that we had 8 mutual elections and 4 mutual rejections in our group, and an index of cohesion of 0.06 with a coefficient of cohesion of 0.12 that showed us that our volleyball team is cohesive and united, the group leaders wer…
Collaborative Governance in Portugal – Yes or No? A critical approach based on an empirical survey
2019
Collaborative governance can be defined as a concerted type of decision-making and collective action in which government bodies and private sector stakeholders interact as equal partners with the aim of achieving outcomes of interest for both parties. In practical terms, this is a type of governance where special meetings and negotiations are held – typically in somewhat elitist and secretive settings – with the aim of defining shared responsibilities and benefits associated with joint public-private ventures. Academic authors in favour of the adoption of collaborative governance in Portugal tend to present a rather positive view on the merits of this approach. They argue that it is potenti…
Validation of a questionnaire for young women to assess knowledge, attitudes and behaviors towards cervical screening and vaccination against HPV in …
2014
Background: Despite knowledge about HPV may be an important determinant for vaccine acceptance and uptake, only few studies have assessed HPV-related knowledge in young females. The aim of this study was to assess the reliability and validity of the questionnaire, in Italian women ≥18 years old, as a tool to examine knowledge, attitudes and behaviors towards screening and vaccination against HPV and reliable source of information. Methods: The questionnaire was administered to 30 girls in anonymous, voluntary and self -administered form with close-ended type of questions, except for the socio-demographic characteristics. It was composed in 3 sections for a total of 69 items. Participation i…
Religion and Civil Society: Theoretical Reflections
2013
Using World Values Survey data, this chapter begins with the global distinctiveness of European societies in terms of both religious vitality and support for the public role of religion. They exhibit a secularity that has been challenged in recent years by an unexpected return of religion as a contentious public issue. The chapter then asks, which theories in the social sciences can help to think constructively through the challenges of religion and civil society in such media-rich, religiously diverse, consumer-oriented secularised societies? It begins with sociology of religion, arguing that while secularisation and rational choice theories shed light on some developments, their conceptua…
Complementary and alternative treatment methods in children with cancer: A population-based retrospective survey on the prevalence of use in Germany.
2008
Abstract Introduction Few studies have been conducted to date on the prevalence of use of complementary and alternative treatment methods (CAMs) in paediatric oncology, and those that have been conducted are often not representative. We therefore decided to study a representative sample of children with cancer in the German population. Patients and methods The study took the form of a retrospective survey amongst all parents whose children were first diagnosed with a disease covered by the German Childhood Cancer Registry in 2001. The primary objectives of the survey were to establish the prevalence of use of CAM and the factors related to its use. Results Of the 1595 questionnaires sent ou…
SDN@home: A Method for Controlling Future Wireless Home Networks
2016
Recent advances in wireless networking technologies are leading toward the proliferation of novel home network applications. However, the landscape of emerging scenarios is fragmented due to their varying technological requirements and the heterogeneity of current wireless technologies. We argue that the development of flexible software-defined wireless architectures, including such efforts as the wireless MAC processor, coupled with SDN concepts, will enable the support of both emerging and future home applications. In this article, we first identify problems with managing current home networks composed of separate network segments governed by different technologies. Second, we point out t…
Adoption of Constrained Application Protocol
2016
Among billions of Internet enabled devices that are expected to surround us in the near future, many will be resource constrained, i.e., will have limited power supply, processing power and memory. To cope with these limitations, the Constrained Application Protocol (CoAP) has been recently introduced as a lightweight alternative to HTTP for connecting the resource limited devices to the Web. Although the new protocol offers solid technical advantages, it remains uncertain whether a successful uptake will follow, as it depends also on its economic feasibility for the involved stakeholders. Therefore, this paper studies the techno-economic feasibility of CoAP using a systematic methodologica…
