CO2 Reduction to CO in Water: Carbon Nanotube-Gold Nanohybrid as a Selective and Efficient Electrocatalyst.

A gold-based nanostructure has been demonstrated as promising materials for the selective electroreduction of CO2 to CO in aqueous conditions. In this work, we present a carbon nanotube-gold nanohybrid as a selective and efficient electrocatalyst for the reduction of CO2 in 0.5 m NaHCO3 . The hybrid material exhibits remarkable activity with a current density of 10 mA cm(-2) at -0.55 V versus standard hydrogen electrode with a stable CO production rate (0.52 μmol s(-1) ) after 4 h electrolysis. Monodispersed gold nanoparticles anchored on carbon nanotubes through a layer-by-layer method allows very little Au loading and thus minimization of the cost of electrode fabrication with a mass activity up to 100 A g(-1) at -0.55 V versus reversible hydrogen electrode. It is 33 times higher than a previous report for monodisperse Au nanoparticles (3 A g(-1) ) while ensuring selectivity (70 % faradaic yield of CO) at comparable reduction potential.
Role of lattice mismatch and surface chemistry in the formation of epitaxial semiconductor-insulator interfaces.

The formation of SrF{sub 2}/Si(111) and Ge/CaF{sub 2}/Si(111) interfaces is studied with photoemission and compared to previous results for the CaF{sub 2}/Si(111) interface. The interface between SrF{sub 2} and Si(111) is found to be nonstoichiometric, similar to the interface between CaF{sub 2} and Si(111): the bonding is between Si and the cation, with a layer of fluorine missing at the interface. In the case of Ge growth on CaF{sub 2}/Si(111), a variety of effects are noted: The CaF{sub 2}/Si(111) valence-band offset is reduced by about 1 eV upon deposition of Ge at room temperature. The sticking coefficient of the Ge is significantly increased by preparing the CaF{sub 2} surface with electron bombardment to remove the top layer of fluorine. For both the irradiated and nonirradiated cases, annealing of thin room-temperature-deposited films resulted in Ge island formation.
A Mechanism to Measure the Routing Metrics along a Point-to-Point Route in a Low-Power and Lossy Network

This document specifies a mechanism that enables a Routing Protocol for Low-power and Lossy Networks (RPL) router to measure the aggregated values of given routing metrics along an existing route towards another RPL router, thereby allowing the router to decide if it wants to initiate the discovery of a better route.
Transbronchial Biopsy in Lymphangiomyomatosis of the Lung HMB45 for Diagnosis

We have investigated the presence of smooth muscle cells with immunoreactivity for melanoma-related marker HMB45 in pulmonary lymphangiomyomatosis (PLAM). Of 75 lung specimens, including a variety of lesions (obtained with both transbronchial and open lung biopsies), only PLAM (six specimens from three patients) showed the presence of HMB45-positive cells. In addition, 20 specimens of normal lung were unreactive with this monoclonal antibody. It is concluded that the smooth muscle cells of PLAM regularly exhibit a peculiar phenotype, characterized by HMB45 immunoreactivity, distinct from other smooth muscle proliferations; and the histological diagnosis of PLAM can be made when only a transbronchial biopsy is available.
Greenfield Foreign Direct Investment and Structural Reforms in Europe: what factors determine investments?

Greenfield FDI flows into EU countries account for a non-negligible share of total EU FDI. They create new capital assets and additional production capacity which are important elements to support the transition to a stronger European growth path. This project investigates determinants of Greenfield FDI flows into the EU countries using sectoral data on bilateral greenfield FDI flows and associated job creation for the 2003-2014 period. The dataset covers the 28 EU countries and also includes as country of origin the main non-EU investors. A gravity model explaining FDI from distance indicators and policy variables is built, while controlling for other important factors, employing Heckman two-step selection procedure. The results suggest that the business climate (from World Bank's Doing Business) and product market regulations (from OECD's PMR) are important determinants of greenfield investment in the EU. This project provides additional evidence on the importance of removing unnecessary regulatory barriers to investment and could help in the discussion on the Investment Plan for Europe.
Production of α-Galactosidase by Aspergillus oryzae through solid-state fermentation and its application in soymilk Galactooligosaccharide hydrolysis

α-Galactosidase was produced by Aspergillus oryzae on red gram plant waste-wheat bran based media in solid-state fermentation (SSF). Optimum temperature for α-galactosidase production was 35 0C and upto 4 cm of bed height of substrate had no inhibitory effect on enzyme production. Hydrolysis of galactooligosaccharides in soymilk was carried out by α-galactosidase. Optimum temperature and pH for the hydrolysis of raffinose and stachyose of soymilk were 550C and 5.2-6.2, respectively. The enzymatic treatment for 3 h completely removed the raffinose oligosaccharides in soymilk. Crude extract also showed considerable amount of invertase activity.
Teaching cognitive rehearsal as a shield for lateral violence: an intervention for newly licensed nurses.

BACKGROUND Recent literature defines lateral violence as nurses covertly or overtly directing their dissatisfaction inward toward each other, toward themselves, and toward those less powerful than themselves. Newly licensed nurses are an identified group that is vulnerable to lateral violence during their socialization to nursing practice. The use of cognitive rehearsal, an applied cognitive-behavioral technique, was used as an intervention and the theoretical underpinning for this study. METHOD Twenty-six newly licensed nurses hired by a large acute care tertiary hospital in Boston, Massachusetts, participated in an exploratory descriptive study. They were taught about lateral violence in nursing practice and the use of cognitive rehearsal techniques as a shield from the negative effects of lateral violence on learning and socialization. Small laminated cueing cards with written visual cues for the appropriate responses to the most common forms of lateral violence were provided. One year later, videotaped focus groups designed to collect qualitative data about the applied intervention were conducted. RESULTS Twenty-six newly licensed nurses in three different focus groups were videotaped responding to six open-ended questions designed to elicit information on their experience with lateral violence, use of cognitive rehearsal as an intervention, and the overall socialization process. CONCLUSIONS Knowledge of lateral violence in nursing appeared to allow newly licensed nurses to depersonalize it, thus allowing them to ask questions and continue to learn. The learned cognitive responses helped them confront the lateral violence offender. Confrontation was described as difficult but resulted in the resolution of the lateral violence behavior. Overall, the retention rate in this study population was positively affected.
The Heterogeneity of Founding-Family Firms: Governance, Firm Policy, Economics, and Ownership Dynamics in Lone Founder, Family Founder, and Heir Firms

Founders and founding-families are amongst the most influential individual blockholders of publicly-listed firms worldwide. Yet, their inherent heterogeneity resulted in mixed evidence on family firm effects in existing studies. This work presents a conceptual approach based on three particular owner identity types—lone founders, family founders, and heirs. This differentiation is applied in advanced econometrical methods leading to economically important insights on owner identity related particularities in corporate governance, policy decisions, performance, and long-term orientation.
Vinyl Chloride Propellant in Hair Spray and Angiosarcoma of the Liver among Hairdressers and Barbers: Case Reports

Abstract Two cases of angiosarcoma of the liver (ASL) are, to the best of our knowledge, the first literature reports of such cases identified among hairdressers and barbers who used hair sprays containing vinyl chloride (VC) as a propellant. The cases were exposed to VC aerosols between 1966 and 1973, for 4–5 year periods. Modeling indicates estimated peak levels of VC exposure ranging from 129 ppm to 1234 ppm, and average exposure ranging from 70 ppm to 1037 ppm, based upon assumptions of use and number of air exchanges per hour. As ASL is a sentinel cancer for exposure to VC, identification of these cases raises concern about the contribution of VC to hepatocellular carcinoma (HCC), a much more common type of liver cancer, as well as other VC-related cancers among hairdressers and barbers. Had manufacturers acted in a responsible manner, VC never would have been introduced as a propellant into consumer products such as hair sprays, pesticides, and paints.
Identity-based construction for secure and efficient handoff authentication schemes in wireless networks

With the rapid development of computer networks, wireless technologies find important applications in roaming communication. In this scenario, practical needs initiate the demand for a secure and efficient handoff authentication scheme. To the best of our knowledge, however, there exists no scheme that can simultaneously provide robust security properties and enjoy desirable efficiency. In this paper, we first examines the security of the scheme proposed in International Conference on Communications 2007 by Kim et al. and demonstrates that the scheme of Kim et al. fails to achieve perfect forward/backward secrecy. Furthermore, we propose a new identity-based construction for secure and efficient handoff authentication schemes, in which an identity-based online/offline encryption scheme is the primary ingredient. Compared with the scheme of Kim et al., our construction enjoys desirable efficiency in terms of the computation cost and the communication cost. To be specific, the developed scheme not only realizes a seamless handoff with key agreement, but also provides perfect forward/backward secrecy, which has never been achieved in any existing handoff-related schemes. Therefore, our construction is more suitable for handoff authentication in the wireless applications environment. Copyright © 2012 John Wiley & Sons, Ltd.
Synthesis and Antiproliferative Activity of 2,5-bis(3′-Indolyl)pyrroles, Analogues of the Marine Alkaloid Nortopsentin

2,5-bis(3′-Indolyl)pyrroles, analogues of the marine alkaloid nortopsentin, were conveniently prepared through a three step procedure in good overall yields. Derivatives 1a and 1b exhibited concentration-dependent antitumor activity towards a panel of 42 human tumor cell lines with mean IC50 values of 1.54 μM and 0.67 μM, respectively. Investigating human tumor xenografts in an ex-vivo clonogenic assay revealed selective antitumor activity, whereas sensitive tumor models were scattered among various tumor histotypes.
XRR and FE-SEM studies of nano-multi-layer ceramic thin films with periodic structures

Nano-multi-layer (NML) ceramic thin films with the periodic (ITO/AlON)n and (ITO/SiOx)m structures were fabricated by the magnetron sputtering. The nano-size of film thickness was characterized by x-ray reflection (XRR) technique and field emission scanning electron microscopy (FE-SEM). The non-destructive XRR technique was able to analyze the NML films under sub-nano-meter-grade resolution quickly and precisely. From the XRR theoretical studies, two methods were used to simulate the characterization result in this study, the multiple-beam-interference (MBI) recursive method and the characteristic matrix method. Both methods show same calculation results. Finally, the periodic thickness and uniformity of NML thin films were compared by XRR and FE-SEM.
Monoclonal antibodies against colonization factor antigen I pili from enterotoxigenic Escherichia coli

Hybridomas secreting monoclonal antibodies directed against intact colonization factor antigen I pili have been produced by the fusion of spleen cells from immunized BALB/c mice with NS1/SP2 myeloma cells. The four monoclones with the highest antibody titer, as detected by enzyme-linked immunosorbant assay (ELISA), were chosen for antibody amplification by production of mouse ascitic fluid. These four were examined for antibody specificity by ELISA and immunoblot assays, using six different pilus types. Three of the four monoclonal isolates were specific for only colonization factor antigen I pili in both assays, whereas the remaining isolate showed a distinct cross-reactivity with K99 pili in the ELISA assay but not in immunoblot analysis. These results indicate that this monoclone may be recognizing a common structural element between the two adhesive pilus types.
Reference generation techniques for active power line conditioners

Reference generation is very important in the control of power line conditioners. This paper presents some algorithms both for single-phase and three-phase systems very suitable for reference generation and digital implementation. The key of the proposed algorithm is the implementation and tuning of Moving Average FIR filters (MVAs). Thanks to the rapid step-response and good harmonic/noise cancellation of MVAs, proposed algorithms have a very good performance both in steady-state and under transients. A frequency adaptive filter configuration has also been proposed in order to improve the dynamics of the algorithms under input frequency shifts from the nominal one. Zero steady-state phase error is achieved with this configuration. A prototype of Active Power Filter (APF) and its control has also been proposed and implemented in a rapid prototyping platform (dSpace DS1103). This prototype is based on a feedforward control scheme implementing a current controller suitable for harmonic compensation. The reference generation of this control algorithm is based on the previous approaches. Experimental results prove the suitability and high performance of the proposals.
How to act ? Implementation and evolution of the PES conductor role: The Belgian PES in Flanders as a case study

Public Employment Services (PES) are increasingly affected by changes in the economy and labour markets. Rather than focusing on the imperative for change (what to do), this paper focuses on the action (how to do it). Our starting point is that to deal with the current changes in governing and implementing tasks in advanced economies, PES needs new ways of making governance work. The aim is to consider how the move from ‘actor’ to ‘regisseur’ (Conductor) as a model for labour market governance affects the role of PES. This new role of conductor is a key element of the PES EU 2020 Strategy Output Paper, adopted at the end of the Danish Presidency in June 2012. The purpose of the PES EU 2020 Strategy Output Paper is to establish a Vision for PES delivery by 2020. It describes the necessary elements to create a modernised service to deliver the EU 2020 Employment Strategy. It calls for a shift from a traditional employment service to a labour market ‘conductor’. Implementing this Vision demands that PES offer a wider set of services to enable various transitions over the life-cycle and to support new customers (workers, inactive groups) with no traditional links to PES. PES therefore need to become enabler, coach and also a ‘conductor’ and facilitator in the labour market by building partnerships with other labour market actors. Based on the individual case study of the Belgian PES (Flanders), we conclude that the label of ‘conducting’ means more than just coordination through partnerships and networks. In practice, there is an evolution from a single mode of governance towards a multiple mode combining characteristics from all three modes of governance, i.e. hierarchy, markets and networks. A key element of the conducting role is the interaction with other actors, regardless of the mode of governance. Moreover, the mix of governance is changing over time. A key factor for PES in our case study, and probably also in other advanced PES systems, is keeping vital labour market information and matching processes under public control in an increasingly digitalised labour market. In this way, thinking of PES as a conductor is not the end of PES as we know but rather the beginning of a process of reinventing PES as a prime public service. The paper is structured as follows. In section 1, we briefly introduce the PES 2020 Vision, the intended changes to the role of PES and the subsequent conductor role as described in the policy document. Section 2 gives an overview of the different types of governance and meta governance, followed by a discussion of how the PES 2020 Strategy refers to it. Following this analytical section, section 3 offers an in-depth review of conducting by the Flemish PES based on four main activities: tendering, local job shops, public-private partnerships and digital services. Finally, section 4 offers a discussion of lessons learned, followed by a conclusion.
The Impact of Supply Chain and Business Process Managements on Firm Performance: The Mediating Effect of Competitive Advantage: Part 1 Constructing Hypotheses

Building business competence is a necessity for firms’ survival and long term effectiveness in today’s rival business environment. This paper discusses how supply chain and business process managements are instrumental in building firms’ competitive advantage and for better performance outcomes. Supply chain and business process management practice antecedents were identified from prier literature. We presented an integrated framework of SCM and BPM. Based on this framework we constructed 6 research hypotheses. In future research we will test hypotheses based on data from real firms. We will also show the empirical test results if both SCM and BPM are essential practices for the improvement of firms’ overall performance measures.
Reactive Load Balancing During Failure State in IP Fast Reroute Schemes

: To improve reliability of IP networks against link / node failure, several IP fast reroute schemes have been proposed so far. They proactively compute backup paths and activate them when failure occurs to prevent packets from losing at the failure link / node. However, it is known that network performance considerably degrades in the failure state of IP fast reroute schemes, because congestion hot spots often appear near the failure link / node. In this paper, we propose a reactive load balancing method that can be applied to the major IP fast reroute schemes that covers single failure. Our scheme works when an IP fast reroute scheme is activating its backup paths, and reduces the degradation of network performance due to failure. In our load balancing scheme, with the overhead of a few bit ﬁeld on packet header, we can largely reduce the performance degradation in the failure state and mostly keep the throughput as it was in the normal state where no failure exists.
Motives and Perceived Consequences of Nonmedical ADHD Medication Use by College Students

Objective: This study examines why college students without a prescription take ADHD medication, what they perceive the consequences of this to be, and whether attention problems are associated with this behavior. Method: More than 3,400 undergraduates attending one public and one private university in the southeastern United States completed a Web-based survey. Results: Nonmedical ADHD medication use in the prior 6 months was reported by 5.4% of respondents and was positively associated with self-reported attention difficulties. Enhancing the ability to study was the most frequent motive reported; nonacademic motives were less common. Students perceived nonmedical use to be beneficial despite frequent reports of adverse reactions. Conclusion: Students without prescriptions use ADHD medication primarily to enhance academic performance and may do so to ameliorate attention problems that they experience as undermining their academic success. The academic, social, and biomedical consequences of illicit ADHD medication use among college students should be researched further. (J. of Att. Dis. 2009; 13(3) 259-270)
Marketing Analytics for High-Dimensional Assortments

textabstractOver the past two decades online retailing has become ubiquitous and today’s large online retailers enable customers to purchase virtually any product. As a consequence product assortments at such retailers are of a different order of magnitude compared to the traditional brick-and-mortar stores. In this dissertation model-based methods are presented that can be used to model purchase decisions in such high-dimensional product assortments. These methods are able to accurately predict at the individual customer level which product will be purchased next out of the large assortment. In addition, the methods provide substantive insights in the patterns that underlie the observed purchase behavior. The applicability of such methods in practice hinges on their scalability and this holds especially true for online retailers. Model results should be rapidly obtained and the estimation time should not significantly increase in case the customer base or product assortment expands. Scalability is therefore a focal point in this dissertation. The methods introduced are adaptations and extensions of fast scalable methods from the machine learning literature that make these methods also suitable for the online retailing context. This ensures that estimation times remain feasible even if the size of the retailer increases and opens the way for advanced model-based marketing analytics in high-dimensional assortments.
The effect of interior planting on health and discomfort among workers and school children

ADDITIONAL INDEX WORDS. benefits of plants, foliage plants, fluorescent lighting, full-spectrum lighting, human-horticulture relationships, human issues in horticulture, human well-being, mucus membrane symptoms, neuropsychological symptoms, people-plant interactions SUMMARY. Plants are widely used in building environments; however, studies reporting the health and discomfort symptoms of people in response to indoor foliage plants are few. The objective of the presented studies was to assess the effect of foliage plants or a combination of foliage plants and full-spectrum fluorescent lamps on self-reported health and discomfort complaints in three different work environments: an office building, an X-ray department in a Norwegian hospital, and a junior high school. Health and discomfort symptoms were found to be 21% to 25% lower during the period when subjects had plants or plants and full-spectrum lighting present compared to a period without plants. Neuropsychological symptoms, such as fatigue and headache, and mucous membrane symptoms, such as dry and hoarse throat, seemed to be more affected by the treatments than skin symptoms, such as itching skin.
