Nanoscale ear drum: graphene based nanoscale sensors.

2012

The difficulty in determining the mass of a sample increases as its size diminishes. At the nanoscale, there are no direct methods for resolving the mass of single molecules or nanoparticles and so more sophisticated approaches based on electromechanical phenomena are required. More importantly, one demands that such nanoelectromechanical techniques could provide not only information about the mass of the target molecules but also about their geometrical properties. In this sense, we report a theoretical study that illustrates in detail how graphene membranes can operate as nanoelectromechanical mass-sensor devices. Wide graphene sheets were exposed to different types and amounts of molecul…

Development of a dielectric spectroscopy technique for the determination of apple (Granny Smith) maturity

2010

Abstract Dielectric measurements of apple were done during its maturity in order to find relations with apple physiological compounds (sugar content, malic acid). An Agilent 85070E open-ended coaxial probe connected to an Agilent E8362B vector network analyzer were used in these experiments. All determinations were made at 30 °C from 500 MHz to 20 GHz. These assays were performed in order to consider the potential use of dielectric spectroscopy for determining the state of fruit maturity. Good correlations among apples Thiault Index with a new defined Dielectric Maturity Index were found. The Dielectric Maturity Index was related to loss factor at two punctual frequencies (0.5 GHz and dipol…

Experimentelle Untersuchungen �ber die ?-Mercaptobrenztraubens�ure-Transsulfurase

1961

Ausgehend von der Feststellung einer Anreicherung von SH-tragenden Stoffen beim Verhornungsprozes wurden Schuppen, Blasendecken, Hautblasen-und Blutserum auf das Vorkommen des SH-Gruppen-ubertragenden Ferments MBTS-Transsulfurase untersucht. Durch das Fehlen des Enzyms bleibt die Frage nach dem Entstehungsmechanismus der SH-Verbindungen weiterhin offen.

Disentangling the dynamics of social assistance: A linked survey—Register data cohort study of long-term social assistance recipients in Norway

2020

Social assistance is a means-tested benefit that is supposed to be a short-term, temporary economic support. Understanding why some individuals are in repeated or continuous need of social assistance is thus of obvious policy relevance, but the dynamics of social assistance receipt remain poorly understood. In 2005, a survey among long-term recipients of social assistance in Norway collected data on (a) childhood disadvantages, (b) health status, (c) health behaviors, (d) psychological resources, and (e) social ties, in addition to basic sociodemographic information. This rich survey data has been linked with tax register data from 2005–2013, enabling us to explore the detailed characterist…

Macroeconomic determinants of Peruvian migration flows

2020

The objective of this paper is to determine the variables associated with the weight that Peruvian immigration has in the total immigration in Chile for the period 2005-2014. The initial hypothesis is that the Peruvian migratory flow has a social and economic component. The results showed that an increase in the Human Development Index (HDI) in favor of Chile increases the migratory flow. On the other hand, a larger education budget in favor of Chile decreases the migratory flow of Peruvian citizens.

China Spillovers: New Evidence from Time-Varying Estimates

2017

The recent “rebalancing” of China’s economy has raised concerns that the country’s growth slowdown may have large global implications. This note looks at this issue by analyzing the effects of China’s growth shocks on the output of other countries and how these effects have changed over time. Estimates indicate that the magnitude of China’s spillovers has steadily increased during the last two decades, but remains yet limited. Spillovers are larger in neighboring (Asian) countries and in emerging markets and developing economies. Trade linkages remain main transmission channels. In addition, a negative shock in China has (marginal) positive effects for net commodity importers wh…

The Role of the Brand on Choice Overload

2019

Current research on choice overload has been mainly conducted with choice options not associated with specific brands. This study investigates whether the presence of brand names in the choice set affects the occurrence of choice overload. Across four studies, we find that when choosing among an overabundance of alternatives, participants express more positive feelings (i.e., higher satisfaction/confidence, lower regret and difficulty) when all the options of the choice set are associated with familiar brands, rather than unfamiliar brands or no brand at all. We also find that choice overload only appears in the absence of brand names, but disappears when all options contain brand names—eit…
