Application of pressurized fluid extraction to determine cadmium and zinc in plants

2006

Abstract A procedure for the determination of Cd and Zn in plants is proposed. The metals are extracted by pressurized fluid extraction (PFE). Operational conditions are: pressure 1500 psi, temperature 75 °C, static time 5 min, flush volume 35%, purge time 60 s, cycles 1 and 1,2-diaminocyclohexane- N , N , N ′, N ′-tetraacetic acid (CDTA) 0.01 M at pH 4.5 as extracting solution. Determination of Zn is carried out by flame atomic absorption spectroscopy and depending on the concentration level, Cd content is determined by flame or electrothermal atomic absorption spectroscopy. Certified samples of Virginia tobacco leaves, tea leaves, spinach leaves, poplar leaves, a commercial spinach sample…

Psychometric properties of the Cyber-Violence Scale in Adolescent Couples (Cib-VPA)

2018

Resumen La utilización que los adolescentes hacen de las redes sociales, móviles e internet, para ejercer violencia hacia la pareja resulta preocupante. Por esta razón, es necesario disponer de instrumentos fiables, específicos para población adolescente y que permitan evaluar tanto situaciones de acoso como de victimización. El objetivo de este estudio fue analizar las propiedades psicométricas de la Escala de Ciber-violencia en Parejas Adolescentes (Cib-VPA). Esta escala consta de dos subescalas, ciberacoso perpetrado y cibervictimización, con 10 ítems cada una relativos a conductas agresivas y de control que pueden ser perpetradas o sufridas a través de redes sociales en parejas adolesce…

First Chemosensor for Selective Detection and Quantification of L-4-Hydroxyproline in Collagen and Other Bio Samples.

2017

Amino pyridine-based rhodamine conjugate (APR) has been developed as a first chemosensor for selective detection and quantification of L-4-Hydroxyproline (Hyp). The “turn-on” fluorescence property of the chemosensor makes it unique for easy estimation of Hyp in collagen and biological samples. peerReviewed

Stable isotopes in monitoring terrestrial arthropods

2022

Monitoring of arthropods focuses typically on changes in population and range size over time. Yet, there are a myriad of other aspects that could and should be monitored under the ongoing global and local environmental change. Stable isotope analysis, widely employed in short-term ecological studies, has potential in long-term monitoring of arthropods. Here we discuss the use of stable isotopes in monitoring terrestrial arthropods, provide some empirical examples of the use of bulk tissue samples in stable isotope analysis, and outline future directions in using compound-specific stable isotope analysis in monitoring. We performed a literature search for 2012–2021 to see if stable isotopes …

Psychiatrists' Attitudes Toward Disruptive New Technologies: Mixed-Methods Study

2018

Background Recent discoveries in the fields of machine learning (ML), Ecological Momentary Assessment (EMA), computerized adaptive testing (CAT), digital phenotype, imaging, and biomarkers have brought about a new paradigm shift in medicine. Objective The aim of this study was to explore psychiatrists’ perspectives on this paradigm through the prism of new clinical decision support systems (CDSSs). Our primary objective was to assess the acceptability of these new technologies. Our secondary objective was to characterize the factors affecting their acceptability. Methods A sample of psychiatrists was recruited through a mailing list. Respondents completed a Web-based survey. A quantitative…

Psychometric properties of the «Spanish Burnout Inventory» (SBI) in a sample of Italian health professionals: a gender perspective

2017

El objetivo de este estudio fue analizar las propiedades psicométricas del Cuestionario para la Evaluación del Síndrome de Quemarse por el Trabajo (CESQT) en una muestra de profesionales de la salud italianos. La muestra estuvo formada por 695 participantes (453 profesionales de enfermería y 242 médicos). Según el género se identificaron 451 mujeres (64.9%) y 244 hombres (35.1%). El CESQT está formado por 20 ítems que se distribuyen en cuatro dimensiones: Ilusión por el trabajo (5 ítems), Desgaste psíquico (4 ítems), Indolencia (6 ítems), y Culpa (5 ítems). La estructura factorial se analizó mediante análisis factorial confirmatorio. Todos los ítems presentaron valores adecuados para los pa…

Assessing the Economy for the Common Good Measurement Theory Ability to Integrate the SDGs into MSMEs

2020

Over the past decades, sustainability and corporate sustainability have gained a lot of attention. Currently, the focus of attention has shifted to the integration of the Sustainable Development Goals (SDGs) into businesses operation. The extant literature points to the proposed frameworks as not fitting micro, small, and medium-sized enterprises (MSME) reality and, also, to a lack of empirical evidence in this field. With research at the intersection of business and SDGs still being scarce, the Economy for the Common Good (ECG) model allows operationalizing the SDGs employing its novel measurement theory. The present study is aimed at completing the statistical validation process of the EC…

Development and Preliminary Validation of Social Media as an Educational and Professional Tool Student Perceptions Scale (SMEPT-SPS)

2021

Although social media has an increasing presence both in university and sports settings, in the sports-management education context, no instruments (without being focused on one particular social-media platform, e.g., Facebook and Twitter) have been developed and validated that globally allow the academy to explore the perceptions of sports-management students concerning the educational and professional learning potential that these tools offer. Therefore, this research’s main objective is to develop and perform a preliminary validation of the social media as an educational and professional tool student perceptions scale (SMEPT-SPS). This study sample was composed of 90 Spanish undergraduat…

Decentering, Acceptance, and Non-Attachment : Challenging the Question "Is It Me?"

2021

Among mindfulness measures the three constructs acceptance, decentering, and non-attachment are psychometrically closely related, despite their apparent semantic differences. These three facets present robust psychometric features and can be considered core themes in most “third wave” clinical models. The aim of the present study was to explore the apparently different content domains (acceptance, decentering, and non-attachment) by administering various psychometric scales in a large sample of 608 volunteers. Resilience and depression were also assessed. Exploratory and confirmatory factor analyses performed in two randomly selected subsamples showed a bifactor approximation. The explained…
