This chapter focuses on the use of doped carbon nanomaterials in catalysis. The availability of carbon nanotubes in the ‘90s and graphene about 10Â years later, prompted the development of fundamental research and novel nanotechnologies. We discuss this topic from a point of view that links fundamental surface science to the field of catalysis, in order to present the state of the art.
The study presents a political economic analysis of spatial inequality in Tehran focusing on four sectors of social reproduction, namely, housing, healthcare, education, and transportation. The study argues that spatial inequality is rooted in the peculiarities of Iranian capitalism. Struggling with low productivity, the manufacturing sector needs wages to remain low and unemployment to remain hig
This paper presents a decomposition strategy applicable to DAE constrained optimization problems. A common solution method for such problems is to apply a direct transcription method and to solve the resulting non-linear program using an interior point algorithm, where the time to solve the linearized KKT system at each iteration is dominating the total solution time. In the proposed method, the s
Ergonomics are, in most cases, focusing on the human being when evaluating assembly system designs. This results in the human performance being expressed isolated from the technical environment. On the other hand, technicians are prone to concentrate on the hardware. These conditions underline the need to pursue a more integrated evaluation and design procedure in order to avoid the drawbacks of t
A magnetic particle-based immuno-supported liquid membrane assay (m-ISLMA) based on chemiluminescence detection of a horseradish peroxidase-labeled hapten tracer that allows sample cleanup, analyte enrichment, and detection in a single analysis unit has been developed. Antibodies were immobilized on magnetic beads, and their position in the acceptor was controlled by two alternating opposing elect
The mechanism of action for the anti-arthritic effect of methotrexate (MTX) was investigated in rats with antigen-induced arthritis (AIA). Arthritis intensity was quantified as area under the curve (AUC) for the joint swelling. The response to MTX was in several respects similar to what is seen in the clinic. The drug reduced the AUC in a dose-dependent manner after oral weekly (2-4 mg/kg/week) or
In this paper we investigate the LHC potential for discovering doubly charged vector bileptons considering the measurable process p, p -> e(-/+) e -/+ mu(+/-) mu(+/-) X. We perform the study using four different bilepton masses and three different exotics quark masses. Minimal LHC integrated luminosities needed for discovering and for setting limits on bilepton masses are obtained for both 7 and 1
The top quark pair production and decay are considered in the framework of the smeared-mass unstable particles model. The results for total and differential cross-sections in vicinity of t (t) over bar threshold are in good agreement with the previous ones in the literature. The strategy of calculations of the higher order corrections in the framework of the model is discussed. Suggested approach
We present a first time-resolved deuterium NMR study on wormlike micelles under shear. For the investigation, a micellar system made of soybean phosphatidylcholine (lecithin), D2O, and cyclohexane was studied in the concentrated regime, in the vicinity of the isotropic/nematic transition but positioned in the equilibrium isotropic phase. The D2O dispersed in the micellar core was used as a probe t
Age-associated and degenerative loss of functional integrity in soft tissues develops from effects of cumulative and subtle changes in their extracellular matrix (ECM). The highly ordered tendon ECM provides the tissue with its tensile strength during loading. As age and exercise collude in the high incidence of tendinopathies, we hypothesized that aged tendons fail due to cumulative damage result
This paper discusses recent advances that have been made in the field of psychometrics, specifically, the application of Rasch analysis to the instrument development process. It emphasizes the importance of assessing the fundamental scaling properties of an instrument prior to consideration of traditional psychometric indicators. The paper introduces Rasch analysis and shows how it has been applie
Six-membered cyclic carbonates are potential monomers for phosgene and/or isocyanate free polycarbonates and polyurethanes via ring-opening polymerization. A two-step process for their synthesis comprising lipase-catalyzed transesterificationofa polyol, trimethylolpropane(TMP) with dimethylcarbonate(DMC)in a solvent-free system followed by thermal cyclization was optimized to improve process effic
A shear-enhanced, cross-flow ultrafiltration module was used to separate cells and proteins from the fermentation broth. Three (fermented) media were studied: rich medium, rich medium with hydrolytic enzymes added after fermentation, and wheat flour hydrolysate. To find a membrane with as high a flux as possible, but still capable of separating cells and proteins from the lactic acid containing br
The aim of the present work is to describe the semantics and the discursive functions from a general cognitivist point of view of the usage of the Present Perfect in the spoken Spanish of Chile, Paraguay and Uruguay. It is argued that cross-linguistic values that prevailing theories often ascribe to perfect, such as continuity, current relevance and recency to the speech time –ST– do not offer a c
The present communication is mainly focused on molecular oxygen detection in porous organic matter, through a tunable diode laser spectroscopy. Initial measurements on wood were preformed in order to illustrate the influence of the density and anisotropy of the sample on the GASMAS-signal. Additional measurements were performed on horticultural produces, in which the concentration of the molecular
This dissertation is a thematic reading of 1,574 items from four Japanese and three Taiwanese major daily newspapers published in the 2000-2008 period. It argues that the concepts of repetition and representation play key structural and narrative roles in the sources and outlines how these concepts operate and how they interrelate on a content level as well as on a level of larger media frameworks
Sammanfattning År 1969 påbörjades en utredning som kom att resultera i lag om samboende gemensamma bostad (1973:651). Det var första gången en lag stiftades som specifikt tog syfte på samboskapet som samlevnadsform. Med lagen infördes en viss övertaganderätt av den bostad som utgjorde sambornas gemensamma hem. Lagstiftningen har utvidgats och modifierats sedan dess. I den nu gällande sambolagen (2Summary In 1969 began a legislative investigation that resulted in the law on cohabitants’ joint dwelling (1973:651). It was the first time a law was passed that specifically aimed at this form of cohabitation. The law introduced a certain right to take over the property which constituted the cohabitees’ common home. The legislation has been extended and modified since then. In the current Cohabit
