Foundations of plasma standards

The field of low-temperature plasmas (LTPs) excels by virtue of its broad intellectual diversity, interdisciplinarity and range of applications. This great diversity also challenges researchers in communicating the outcomes of their investigations, as common practices and expectations for reporting vary widely in the many disciplines that either fall under the LTP umbrella or interact closely with LTP topics. These challenges encompass comparing measurements made in different laboratories, exchanging and sharing computer models, enabling reproducibility in experiments and computations using traceable and transparent methods and data, establishing metrics for reliability, and in translating fundamental findings to practice. In this paper, we address these challenges from the perspective of LTP standards for measurements, diagnostics, computations, reporting and plasma sources. This discussion on standards, or recommended best practices, and in some cases suggestions for standards or best practices, has the goal of improving communication, reproducibility and transparency within the LTP field and fields allied with LTPs. This discussion also acknowledges that standards and best practices, either recommended or at some point enforced, are ultimately a matter of judgment. These standards and recommended practices should not limit innovation nor prevent research breakthroughs from having real-time impact. Ultimately, the goal of our research community is to advance the entire LTP field and the many applications it touches through a shared set of expectations

Direct exfoliation and dispersion of two-dimensional materials in pure water via temperature control

The high-volume synthesis of two-dimensional (2D) materials in the form of platelets is desirable for various applications. While water is considered an ideal dispersion medium, due to its abundance and low cost, the hydrophobicity of platelet surfaces has prohibited its widespread use. Here we exfoliate 2D materials directly in pure water without using any chemicals or surfactants. In order to exfoliate and disperse the materials in water, we elevate the temperature of the sonication bath, and introduce energy via the dissipation of sonic waves. Storage stability greater than one month is achieved through the maintenance of high temperatures, and through atomic and molecular level simulations, we further discover that good solubility in water is maintained due to the presence of platelet surface charges as a result of edge functionalization or intrinsic polarity. Finally, we demonstrate inkjet printing on hard and flexible substrates as a potential application of water-dispersed 2D materials.close1

Where the Sidewalk Ends: Jets and Missing Energy Search Strategies for the 7 TeV LHC

This work explores the potential reach of the 7 TeV LHC to new colored states in the context of simplified models and addresses the issue of which search regions are necessary to cover an extensive set of event topologies and kinematic regimes. This article demonstrates that if searches are designed to focus on specific regions of phase space, then new physics may be missed if it lies in unexpected corners. Simple multiregion search strategies can be designed to cover all of kinematic possibilities. A set of benchmark models are created that cover the qualitatively different signatures and a benchmark multiregion search strategy is presented that covers these models.Comment: 30 pages, 8 Figures, 3 Tables.

Dysthanasia: nursing professionals' perception

Dysthanasia means slow and painful death without quality of life. This study aimed to know whether nurses identify dysthanasia as part of the final process of the lives of terminal patients hospitalized at an adult ICU. This is an exploratory-qualitative study. Data were collected through semi-structured interviews with ten nurses with at least one year of experience in an ICU, and interpreted through content analysis. Results indicate that nurses understand and identify dysthanasia, do not agree with it and recognize elements of orthonasia as the adequate procedure for terminal patients. We conclude that nurses interpret dysthanasia as extending life with pain and suffering, while terminal patients are submitted to futile treatments that do not benefit them. They also identify dysthanasia using elements of orthonasia to explain it.Distanasia significa muerte lenta, con sufrimiento y sin calidad de vida. En esta investigación se buscó conocer si los enfermeros identifican la distanasia como parte del proceso final de la vida de personas en estado terminal, internadas en una UTI para adultos. El estudio es de naturaleza exploratoria, con abordaje cualitativo. Los datos fueron recolectados por medio de entrevista semiestructurada con 10 enfermeros con un mínimo de un año de experiencia en UTI; los datos fueron interpretados por el análisis de contenido. Se obtuvo como resultado que los enfermeros comprenden e identifican la distanasia y se oponen a la misma, presentando elementos de ortotanasia como procedimiento adecuado para pacientes en estado terminal. Se concluye que los enfermeros interpretan la distanasia como el prolongamiento de la vida con dolor y sufrimiento, en el cual los pacientes terminales son sometidos a tratamientos fútiles que no traen beneficios. También identifican la distanasia, usando elementos de la ortotanasia para hacerla explicita.Distanásia significa morte lenta, sofrida e sem qualidade de vida.

Probing the near infrared stellar population of Seyfert galaxies

We employ IRTF SpeX NIR (0.8-2.4 microns) spectra to investigate the stellar population (SP), active galactic nuclei (AGN) featureless continuum (FC) and hot dust properties in 9 Sy 1 and 15 Sy 2 galaxies. Both the starlight code and the hot dust as an additional base element were used for the first time in this spectral range. We found evidence of correlation among the equivalent widths (W) Si I 1.59 microns x Mg I 1.58 microns, equally for both kinds of activity. Part of the W{Na I 2.21 microns} and W {CO 2.3 microns} strengths may be related to galaxy inclination. Our synthesis shows significant differences between Sy 1 and Sy 2 galaxies: the hot dust component is required to fit the K-band spectra of ~90% of the Sy 1 galaxies, and only of ~25% of the Sy 2; about 50 % of the Sy 2 galaxies require a $FC$ component contribution >20%, while this fraction increases to 60% in the Sy 1; also, in about 50 % of the Sy2, the combined FC and young components contribute with more than 20%, while this occurs in 90% of the Sy1, suggesting recent star formation in the central region. The central few hundred parsecs of our galaxy sample contain a substantial fraction of intermediate-age SPs with a mean metallicity near solar. Our SP synthesis confirms that the 1.1 micron CN band can be used as a tracer of intermediate-age SPs. The simultaneous fitting of SP, FC and hot dust components increased in ~150% the number of AGNs with hot dust detected and the mass estimated. The NIR emerges as an excellent window to study the stellar population of Sy 1 galaxies, as opposed to the usually heavily attenuated optical range. Our approach opens a new way to investigate and quantify the individual contribution of the three most important NIR continuum components observed in AGNs.Comment: The paper contains 14 figures and 5 tables.

Occupational stress and work capacity of nurses of a hospital group

The study aimed to evaluate the relationship between occupational stress and the work capacity index of 368 nurses (82.1% of the population) of a Hospital Group. A questionnaire with socio-occupational questions was used as well as two scales: the Job Stress Scale and the Work Capacity Index. The group of nurses was predominantly female (93.2%), worked in care activities (63.9%), had undertaken at least one Postgraduate course (76%) and were satisfied with the unit where they worked (70.5%). Occupational stress was present in 23.6% of the nurses, of these 15.2% presented High Strain work and 8.4% Passive Work. Social Support exercised a significant positive influence on all groups - exposed or not to occupational stress. Regarding the Work Capacity, this was Moderate (28-36 points) for 51.4% of the nurses and Good (37-43 points) for 47.4%. There was no correlation between stress and work capacity.Se trata de un estudio con objetivo de evaluar la relación entre el estrés laboral y el índice de capacidad para el trabajo de 368 enfermeros (82,1% de la población) de un Grupo Hospitalario.
