Facile polymerization of b cyclodextrin functionalized graphene or graphene oxide nanosheets using citric acid crosslinker by in situ melt polycondensation for enhanced electrochemical performance

In this study, we report a facile, environmental friendly route to synthesize water insoluble b cyclodextrin (b CD)/graphene oxide (GO) or reduced graphene oxide (rGO) nanocomposite hydrogels. These nanocomposite hydrogels were synthesized by in situ melt polymerization; first, the b CD was covalently bound to GO to produce b CD/GO, and then b CD/rGO was obtained through in situ reduction of GO by hydrazine. These hybrid materials were polycondensed in the presence of melted citric acid (CT) as a crosslinker. The structures of the obtained macromolecules were characterized by ATR FTIR, Raman spectroscopy, TGA, DTG, DSC, DDSC, XRD, FE SEM, EDAX, and electrochemical impedance spectroscopy, and also by determining the amount of acidic groups and by adsorption of cationic methylene blue. These data have confirmed that b CD/GO or rGO was effectively polymerized using CT through ester linkages. Swelling ratio data shows the ability of these nanocomposites to absorb a large amount of water in their structures, and the b CD polymer/rGO (CDP CT/rGO) gels have higher equilibrium swelling ratios than the corresponding b CD polymer (CDP CT) and CDP CT/GO. The results of cyclic and differential pulse voltammetry electrochemical studies revealed that CDP CT/GO and CDP CT/rGO nanocomposite hydrogels exhibited higher electrochemical responses toward dopamine, tyrosine and uric acid (biomolecules) than unmodified CDP CT. In addition, CDP CT/rGO shows a higher response relative to CDP CT/GO, which is probably due to the restoration of the graphitic network after the reduction of GO. As a result, the improved electrochemical behaviors of these nanocomposites are due to a combination of the chemical properties of b CD, GO or rGO nanosheets, polyester and poly(carboxylic acid)
Interrogating the Key Policy Factors Behind South Korea's Archery Success

This paper aims to interrogate the key policy factors behind South Korea's archery success. Based on our review on the history of Korean archery, two additional key elements in terms of organization and administration were also included to form the analytical framework of this research, aside from Green and Houlihan's four key policy elements. Our analytical framework is thus comprised of two background elements for elite sport development the organizational structure and administration, and four areas of elite sport policy. According to our analytical framework, this paper highlights four key policy dimensions that have influenced South Korea's archery success, as follows: (i) establishment of the Korean Archery Association (KAA) and the involvement of business elites; (ii) emergence of potential full time archers by the identification of, and the support for, young talented athletes; (iii) developments in sport science, coaching, and facilities/equipment; and (iv) the provision of more systematic competition opportunities for elite level archers. In summary, the success of Korean archers might be closely linked to the result of the KAA's staunch strategy and policy initiatives encouraged by the government for international sporting success and the way in which the organization has paid more salient attention to the policy commitments as noted above.

Breaking the double edged sword of effort/trying hard: Developmental equilibrium and longitudinal relations among effort, achievement, and academic self concept.
Venue: Developmental psychology

Ever since the classic research of Nicholls (1976) and others, effort has been recognized as a double edged sword: while it might enhance achievement, it undermines academic self concept (ASC) However, there has not been a thorough evaluation of the longitudinal reciprocal effects of effort, ASC, and achievement, in the context of modern self concept theory and statistical methodology. Nor have there been developmental equilibrium tests of whether these effects are consistent across the potentially volatile early to middle adolescence. Hence, focusing on mathematics, we evaluate reciprocal effects models (REMs) over the first 4 years of secondary school (grades 5 8) relating effort, achievement (test scores and school grades) ASC, and ASC x Effort interactions for a representative sample of 3,144 German students (Mage 11.75 years at Wave 1) ASC, effort, and achievement were positively correlated at each wave, and there was a clear pattern of positive reciprocal positive effects among ASC, test scores, and school grades each contributing to the other, after controlling for the prior effects of all others. There was an asymmetrical pattern of effects for effort that is consistent with the double edged sword premise: prior school grades had positive effects on subsequent effort, but prior effort had nonsignificant or negative effects on subsequent grades and ASC. However, on the basis of a synergistic application of new theory and methodology, we predicted and found a significant ASC x Effort interaction, such that prior effort had more positive effects on subsequent ASC and school grades when prior ASC was high thus providing a key to breaking the double edged sword.
Reinforced and prestressed concrete bridges

The present chapter intends to include the following aspects for reinforced and prestressed concrete bridges: material specifications (US and European standards) different types of cast in situ or precast bridge decks like solid or voided slabs; beams; reinforcing and prestressing systems; details; losses and time dependent effects in prestressing; design considerations (conceptual design, detailed design for ultimate limit state (ULS) serviceability limit state (SLS) dynamic loads, and durability) construction issues; design examples; and case studies. Possibilities for the use of advanced materials (like high performance concrete, lightweight concrete, non metallic reinforcements) also will be discussed.
Does Neighbourhood Ethnic Concentration in Early Life Affect Subsequent Labour Market Outcomes? A Study across Ethnic Groups in England and Wales

The impact of neighbourhood ethnic concentration on ethnic minorities' outcomes is a contested topic, with mixed empirical results. In this paper, we use a large scale longitudinal dataset of England and Wales, covering a 40 year period, to assess the impact of neighbourhood co ethnic concentration in childhood on subsequent adult labour market outcomes. We distinguish the five main minority groups in the UK and develop theoretical expectations about how social interaction mechanisms in the neighbourhood might influence their employment and social class outcomes, given different group (cultural values and ethnic capital) and individual (gender) characteristics. By separating in time explanatory and outcome variables and by controlling for factors that mediate or confound co ethnic concentration such as neighbourhood deprivation, household resources in childhood (i.e. parental social class) and individuals' own education our analytical model tackles potential problems of self selection and endogeneity. Among other findings, we show that greater concentration of co ethnics in the neighbourhood results in substantially lower labour market participation and lower social class for Pakistani and Bangladeshi women but better social class outcomes for Indian men. We link the outcomes for Pakistani and Bangladeshi women to cultural maintenance of more traditional norms, facilitated by greater social interaction. The results for Indian men, instead, suggest the positive role that high levels of group resources or 'ethnic capital' can play. Our study is, we believe, the first to demonstrate a role for co ethnic concentration in childhood in explaining Pakistani and Bangladeshi women's low labour market participation and Indian men's labour market success.
One market, two monies: the European Union and the United Kingdom. Bruegel Policy Brief Issue 2016/01 January 2016

Access to the single market is one of the core benefits of the United Kingdom's membership of the European Union. A vote to leave the EU would trigger difficult negotiations on continued access to that market. However, the single market is not static. One of the drivers of change is the necessary reforms to strengthen the euro. Such reforms would not only affect the euro's fiscal and political governance. They would also have an impact on the single market, in particular in the areas of banking, capital markets and labour markets. This is bound to affect the UK, whether it remains in the EU or not.
Neoliberal Narrative in Times of Economic Crisis: A Political Claims Analysis of the U.K. Press, 2007 14

Using political claims analysis on 1,000 articles from five national newspapers (Daily Mail, The Sun, The Times, The Guardian, and Daily Mirror) this article demonstrates that press coverage of the financial crisis, recession, and austerity in the United Kingdom between 2007 14 drew heavily on a neoliberal discourse. Political, market, and civil society actors discussed the impact of hard times on people using a reductionist neoliberal narrative, framing people as "economic actors" and consistently underplaying any social or political traits. By examining communicative, rather than coordinative, discourse this research expands the focus of previous studies which have examined the embeddedness of ideology in society, and highlights potential links to studies of citizen participation and mobilization.

Market power and the rate of profit

In the Great Leveler, Christophers (2016) argues that the grand narrative of capitalism growth, slowdown, crisis and response can in part be understood in the light of the manner in which markets are organised. Although he recognises that other dynamics also underpin this cycle, Christophers nevertheless argues both that slowdowns have historically coincided with imbalances in the degree to which markets are competitive and that the subsequent recoveries were powered by a rebalancing of the degree of competition. The critical legal arrangements for configuring the degree of competition have been those related to concentration and monopoly on the one hand and those related to the protection of intellectual property on the other. The evidence that Christophers assembles concerns the crises of the 1890s, 1930s and 1970s in the USA and the UK and their subsequent periods of growth and expansion. There is a lot to admire in this book, particularly its recognition of the need to understand theoretically and empirically the details of the changing composition of market competition. The historical detail is impressive indeed. And so is the book's extension of the usual period of reckoning beyond the post Second World War era back to the 1890s. In accounts of capitalist dynamics from now on, the form of the market its level of competitiveness will surely continue to figure in the story, and that is much to Christophers' credit. However, the bare outlines of this story of growth and stagnation do need some historical nuance. In particular, some of the details of the story of profitability and growth can be debated, and to illustrate this comment, I will make three observations. My first observation is that historically the rate of profit is relatively constant, as Christophers writes. Whereas Christophers, like others, takes this to be an intriguing feature of capitalist development, the reason for the fact that economy wide rates of profit are bounded was provided nearly 25 years ago (Farjoun and Machover, 1983) Firms' rates of profit are a stochastic variable. Therefore, as the average rate of profit falls below the average, then rapidly increasing numbers of firms make losses; as those firms go out of business, their capital (and their loss) is removed from the surplus/capital calculation and the rate of profit rises, quite independently of any changes in policy. If, on the other hand, the rate of profit rises above the average, then increasing numbers of (less efficient) firms begin production, dragging down average rates of productivity and raising the demand for labour; these tendencies tend to increase the capital stock faster than they increase the surplus, again independent of any countervailing policies.

A New Hybrid Network Sniffer Model Based on Pcap Language and Sockets (Pcapsocks)

Nowadays, the protection and the security of data transited within computer networks represent a real challenge for developers of computer applications and network administrators. The Intrusion Detection System and Intrusion Prevention System are the reliable techniques for a Good security. Any detected intrusion is based on data collection. So, the collection of an important and significant traffic on the monitored systems is an interesting feature. Thus, the first task of Intrusion Detection System and Intrusion Prevention System is to collect information's basis to treat and analyze them, and to make accurate decisions. Network analysis can be used to improve networks performances and their security, but it can also be used for malicious tasks. Our main goal in this article is to design a reliable and powerful network sniffer, called PcapSockS, based on pcap language and sockets, able to intercept traffic in three modes: connected, connectionless and raw mode. We start with the performances assessment performed on a list of most expanded and most recently used network sniffers. The study will be completed by a classification of these sniffers related to computer security objectives based on parameters library (libpcap/winpcap or libnet) filtering, availability, software or hardware, alert and real time. The PcapSockS provides a nice performance integrating reliable sniffing mechanisms that allow a supervision taking into account some low and high level protocols for TCP and UDP network communications.

Six Port Based Interferometry for Precise Radar and Sensing Applications
Venue: Sensors

Microwave technology plays a more important role in modern industrial sensing applications. Pushed by the significant progress in monolithic microwave integrated circuit technology over the past decades, complex sensing systems operating in the microwave and even millimeter wave range are available for reasonable costs combined with exquisite performance. In the context of industrial sensing, this stimulates new approaches for metrology based on microwave technology. An old measurement principle nearly forgotten over the years has recently gained more and more attention in both academia and industry: the six port interferometer. This paper reviews the basic concept, investigates promising applications in remote, as well as contact based sensing and compares the system with state of the art metrology. The significant advantages will be discussed just as the limitations of the six port architecture. Particular attention will be paid to impairment effects and non ideal behavior, as well as compensation and linearization concepts. It will be shown that in application fields, like remote distance sensing, precise alignment measurements, as well as interferometrically evaluated mechanical strain analysis, the six port architecture delivers extraordinary measurement results combined with high measurement data update rates for reasonable system costs. This makes the six port architecture a promising candidate for industrial metrology.
Experimental study of flexural fatigue performance of reinforced concrete beams strengthened with prestressed CFRP plates

Fiber reinforced polymers (FRPs) have commonly been used for the retrofitting and strengthening of bridges, especially in the strengthening flexural members. Considerable research has been conducted to investigate the static behavior of reinforced concrete (RC) beams strengthened with externally bonded FRP laminates, initially using non prestressed FRPs and more recently using prestressed FRPs. However, the research examining the flexural fatigue behavior of beams with either non prestressed or prestressed FRPs is not adequate. In this paper, seven RC beams (two regular and five beams strengthened with externally bonded non prestressed and prestressed CFRP plates) were studied to examine the effects of the different strengthening methods on the flexural fatigue performance of the beams. Furthermore, the effect of debonding on the fatigue behavior of the strengthened beams was investigated. It is evident from the experimental results that strengthening with prestressed CFRP plates significantly enhanced the monotonic and fatigue performances of reinforced concrete beams. The prestressed CFRP plates significantly reduced the deflection and reinforcing bar stress of the beams. The test results also indicated that under similar loads, the strain range and maximum strain of the reinforcing bars of beams with prestressed CFRP plates were significantly less than those of beams with non prestressed CFRP plates. Moreover, the debonding, observed between the CFRP plate and the concrete during the fatigue test resulted in stress redistributions between the CFRP plate and the reinforcing bars.

Relationship of VEGF/VEGFR with immune and cancer cells: staggering or forward?
Venue: Cancer biology medicine

Vascular endothelial growth factor (VEGF) is primarily known as a proangiogenic factor and is one of the most important growth and survival factors affecting the vascular endothelium. However, recent studies have shown that VEGF also plays a vital role in the immune environment. In addition to the traditional growth factor role of VEGF and VEGF receptors (VEGFRs) they have a complicated relationship with various immune cells. VEGF also reportedly inhibits the differentiation and function of immune cells during hematopoiesis. Dendritic cells (DCs) macrophages, and lymphocytes further express certain types of VEGF receptors. VEGF can be secreted as well by tumor cells through the autocrine pathway and can stimulate the function of cancer stemness. This review will provide a paradigm shift in our understanding of the role of VEGF/VEGFR signaling in the immune and cancer environment.
