Application of matrix solid phase dispersion to the determination of imidacloprid, carbaryl, aldicarb, and their main metabolites in honeybees by liq…

2005

Abstract A method based on matrix solid phase dispersion (MSPD) using C18 as dispersant and dichloromethane–methanol as eluent and liquid chromatography–atmospheric pressure chemical ionization–mass spectrometry (LC–APCI–MS) has been developed for the simultaneous determination of imidacloprid, 6-chloronicotinic acid, carbaryl, aldicarb, aldicarb sulfoxide, and aldicarb sulfone in honeybees. The proposed method was compared with liquid–liquid extraction (LLE) combined with LC–APCI–MS analysis. Spiked blank samples were used as standards to counteract the matrix effect observed in the chromatographic determination. Recovery studies were performed at different fortification levels. Average re…

Electrostatic backscattering by insulating obstacles

2012

AbstractWe introduce and analyze backscattering data for a three-dimensional obstacle problem in electrostatics. In particular, we investigate the asymptotic behavior of these data as (i) the measurement point goes to infinity and (ii) the obstacles shrink to individual points. We also provide numerical simulations of these data.

Acceptance and validity of the methods used to implement a competency based medical education programme in an Intensive Care Department of a teaching…

2021

Abstract Objectives 1. To determine the satisfaction of tutors and residents with a specific methodology used to implement CoBaTrICE. 2. To determine the reliability and validity of the global rating scales designed ad hoc to assess the performance of the residents for training purposes. Design Prospective cohort study. Participants All the residents and tutors of the ICU Department of the Hospital Universitario y Politecnico la Fe de Valencia. Intervention CoBaTrICE implementation started in March 2016, it was based on: (1) Training the tutors in feedback techniques; (2) Performing multiple objective and structured work based assessments to achieve the competences of the program; and (3) T…

QUALITY OF INCLUSIVE EDUCATION, OBSTACLES AND NECESSARY PEDAGOGICAL SOLUTIONS IN WORKING WITH PUPILS WITH AUTISM IN ITALY

2018

Nowadays are increasingly encountered children diagnosed with autism, but there are still serious problems of inclusion of these children in the comprehensive general education system. This is due to various factors. The author of this study many years is working in the schools of special education in Rome, so in the year 2010 started research on inclusion of pupils with autism into the Italian schools. The idea is to transmit the author's knowledge and experience further in Latvia, where inclusion of such pupils into general education schools is still at an early stage because of a lack of both human resources and financial resources, as well in regard of experience and clear understanding…

Contrasting shell growth strategies in two Mediterranean bivalves revealed by oxygen-isotope ratio geochemistry: The case of Pecten jacobaeus and Gly…

2019

International audience; High-resolution stable-isotope ratio data (delta O-18, delta O-18) were used to study growth strategies of two bivalve species, Pecten jacobaeus (calcitic shell) and Glycymeris pilosa (aragonitic shell) from the North Adriatic Sea. The principal objectives of this study were to identify the period of the year when the growth line is formed in the shell of two target species, to identify the main growing season of these two species, to identify the environmental drivers of shell growth, and to evaluate the potential applicability of delta O-18 and delta O-18 values for the reconstruction of environmental variability. Samples were collected from the North Adriatic Sea …

Is the Spectacled WarblerSylvia conspicillataexpanding northward because of climate warming?

2014

Capsule The Spectacled Warbler shows a strictly Mediterranean distribution which is expected to expand northward in response to climate warming. To test this hypothesis, we defined the regular distribution of the species based on the literature and we tested whether: (1) spring temperatures in this area significantly increased between 1967 and 2010; (2) breeding attempts north of the regular range occurred progressively at northern latitudes. Both of these hypotheses were confirmed, supporting the hypothesis that the species is expanding northward because of climate warming.

Novel 1H-pyrrolo[2,3-b]pyridine derivative nortopsentin analogues: synthesis and antitumor activity in peritoneal mesothelioma experimental models.

2013

In this study, we describe the synthesis of new nortopsentin analogues, 1H-pyrrolo[2,3-b]pyridine derivatives and their biological effects in experimental models of diffuse malignant peritoneal mesothelioma (DMPM), a rare and rapidly fatal disease, poorly responsive to conventional therapies. The three most active compounds, 1f (3-[2-(5-fluoro-1-methyl-1H-indol-3-yl)-1,3-thiazol-4-yl]-1H-pyrrolo[2,3-b]pyridine), 3f (3-[2-(1H-indol-3-yl)-1,3-thiazol-4-yl]-1-methyl-1H-pyrrolo[2,3-b]pyridine), and 1l (3-[2-(5-fluoro-1-methyl-1H-indol-3-yl)-1,3-thiazol-4-yl]-1-methyl-1H-pyrrolo[2,3-b] pyridine), which were shown to act as cyclin-dependent kinase 1 inhibitors, consistently reduced DMPM cell prol…

Studies on the antioxidant activity of the essential oil and extract of Tunisian Tetraclinis articulata (Vahl) Mast. (Cupressaceae).

2013

This study analyses the chemical composition and in vitro antioxidant activity of both the essential oil and the 80% aqueous acetone extract of Tetraclinis articulata leaves. The GC-MS analysis of the essential oil identified 66 components that comprise 93.5% of the oil. The major constituents of the oil are: bornyl acetate (31.4%), α-pinène (24.5%) and camphor (20.3%). Antioxidant activities of the samples were determined using four different test systems, namely DPPH, β-carotene/linoleic acid, reducing power and metal chelating activity assay. Test results from the DPPH system showed the strongest radical scavenging activity was exhibited by the 80% aqueous acetone extract (IC(50) = 5.5 µ…

Speaking from above and below -The Gospel of John as metaphorical and narrative reference to a distant reality

2018

The one who is from the earth belongs to the earth and speaks from the earth (Jn 3:31). How can one speak from the earth and at the same time about heavenly things? The Fourth Gospel (FG) creates a tension between these two realms of perception and cognition. To reach beyond or above the earth we have to transcend time and space, our individual context and limited visual horizon. To overcome the obstacle of confined space we can rely on metaphors since their key faculty is to transport (μετα-φέρω). To transcend the limitations of time we can recruit the genre of narration. These two modes of references to a reality that is located and dated beyond our realms are at work in the FG. With Rico…
