Occurrence of pesticide residues in Spanish beeswax
2017
Beeswax from Spain was collected during 2016 to determine pesticide residues incidence. The 35 samples were divided in foundation, old combs, cappings or virgin beeswax to compare pesticide content between groups. Wax was screened for 58 pesticides or their degradation products by QuEChERS extraction and liquid chromatography mass spectrometry (LC-MS/MS). Beeswax was uniformly contaminated with acaricides and, to a much lesser extent, with insecticide and fungicide residues. Virgin followed by cappings were less contaminated than foundation and old combs beeswax. The miticides applied in-hive had a contribution to average pesticide load higher than 95%. Compounds widely used as acaricides, …
A two-year monitoring of pesticide hazard in-hive: High honey bee mortality rates during insecticide poisoning episodes in apiaries located near agri…
2019
Pesticide residues in beebread, live and dead honey bees, together with honey bee death rate were monitored from June 2016 to June 2018 in three apiaries, located near agricultural settings and in wildlands. Dead honey bees were only collected and analyzed when significant mortality episodes occurred and pesticide content in beeswax of each experimental apiary was evaluated at the beginning of the study. Samples were extracted by a modified QuEChERS procedure and screened for pesticides residues by liquid chromatography mass spectrometry (LC-MS/MS). Pesticide hazard in the samples was evaluated through the hazard quotient approach (HQ). Beebread was widely contaminated with coumaphos and am…
Efficiency in the eurobond market: application of nonparametric techniques
2007
The aim of this article is to analyse the efficiency of eurobond issuers within the primary market, from 1995 to 2000. The study includes a reference to theoretical discussion and to the methodology used; detailed explanation of the variables considered which, in order to supplement those strictly financial, include others such as spread from Interest Rate Risk (IRR) and respective swap; rating, duration and size; and macroeconomic fundamentals of the issuer country. Results and conclusions obtained from the static and dynamic efficiency analyses are then illustrated and discussed.
Tear production and intraocular pressure values in clinically normal eyes of whooper swans (<i>Cygnus cygnus</i>)
2018
The objective of this study was to determine the normal range of tear production and values of intraocular pressure (IOP) in clinically normal eyes of whooper swans (Cygnus cygnus). A total of 86 birds: 81 cygnets (6-10 weeks old) and 5 moulting - adult swans (3-6 years old) were examined in this study. Both eyes of all birds underwent a complete ophthalmic examination, including evaluation of tear production with the phenol red thread test (PRTT) and the assessment of the IOP by rebound tonometry, employing the TonoVet® device. The mean ± standard deviation of PRTT values were as follows: all cygnets (81) 22.59±3.48 mm/15s, male cygnets (45) 22.64±3.54 mm/15s, female cygnets (36) 22.53±3.4…
Governance through Economic Paradigms: Addressing Climate Change by Accounting for Health
2016
"Climate change is a major challenge for sustainable development, impacting human health, wellbeing, security, and livelihoods. While the post-2015 development agenda sets out action on climate change as one of the Sustainable Development Goals, there is little provision on how this can be achieved in tandem with the desired economic progress and the required improvements in health and wellbeing. This paper examines synergies and tensions between the goals addressing climate change and economic progress. We identify reductionist approaches in economics, such as 'externalities', reliance on the metric of the Gross Domestic Product, positive discount rates, and short-term profit targets as so…
Sag, wie hältst Du's mit Grün-Rot? Die grün-rote Landesregierung im Urteil der Wähler 2011 bis 2015
2016
In unserem Beitrag analysieren wir, wie die Burgerinnen und Burger den Regierungswechsel und die Ubernahme der Regierungsgeschafte durch die neue grun-rote Regierung wahrgenommen, wie sich die Regierungs- und Parteienzufriedenheit (ausgedruckt durch die hypothetische Wahlentscheidung) im Zeitverlauf entwickelt haben und was die Determinanten der Zufriedenheit sind. Unsere Analysen basieren dabei auf insgesamt sechs reprasentativen telefonischen Befragungen im Zeitraum von November 2011 bis Oktober 2015. Wir konnen zeigen, dass im Laufe der Legislaturperiode die vor der Wahl stattgefundenen Ereignisse mehr und mehr an Bedeutung fur die Bewertung der Regierungsleistung verlieren. Die Landesre…
Long-term esophageal motility changes after thyroidectomy: associations with aerodigestive disorders.
2017
BACKGROUND: Patients undergoing thyroidectomy often complain aerodigestive disorders. In a previous study we showed the associations between voice impairment and proximal acid reflux, swallowing impairment and Upper Esophageal Sphyncter (UES) incoordination and the decrease in UES pressure in thirty-six patients observed before and soon afterwards uncomplicated thyroidectomy. This study investigated the state of post-thyroidectomy esophageal motility changes and its associations with these disorders after 18-24 months. PATIENTS AND METHODS: The thirty-six patients prospectively recruited according to selection criteria (thyroid volume ≤60 ml, benign disease, age 18-65 years, previous neck s…
Evoluzione della linea di riva: un approccio idraulico per il caso studio della spiaggia di Lido Signorino (Marsala)
2014
L’evoluzione della linea di riva, limite tra terra e mare, è causata dall’interazione fra l’energia del moto ondoso e l’assorbimento di questa da parte della spiaggia. Il moto ondoso e le correnti che evolvono lungo il litorale, e in particolare il frangimento e la risalita delle onde sulla spiaggia, hanno un ruolo determinante nei processi fisici costieri più rilevanti. L'obiettivo di questo studio è stato quello di analizzare le variazioni della posizione della linea di riva di una spiaggia, dissipativa e a debole pendenza localizzata nella costa occidentale siciliana. Tale spiaggia, con un’estensione N-S di circa 3,5 km, ricade a sud della città di Marsala, tra due promontori sui quali s…
Language practices in primary schools [in Nairobi] : the teachers' perspectives
2010
ABSTRACT Otieno, Suzanne Adhiambo. LANGUAGE PRACTICES IN PRIMARY SCHOOLS IN NAIROBI: THE TEACHERS’ PERSPECTIVES. A Pro Gradu Thesis in Special Education, University of Jyväskylä, Department of Educational Sciences, 2010. 84 pages. Unpublished Literacy is facilitated by the readiness to comprehend fluently written language and this requires accurate and fluent basic reading skills, good mastery of the language to be read and a lot of practice in reading the particular language. Basic reading skills involve the ability to pronounce written words accurately and this requires appropriate teaching instructions in a language most familiar to the pupils. Research has found that learning to read in…
Particle Swarm Optimization as a New Measure of Machine Translation Efficiency
2018
The present work proposes a new approach to measuring efficiency of evolutionary algorithm-based Machine Translation. We implement some attributes of evolutionary algorithms performing cosine similarity objective function of a Particle Swarm Optimization (PSO) algorithm then, we evaluate an English text set for translation precision into the Spanish text as a simulated benchmark, and explore the backward process. Our results show that PSO algorithm can be used for translation of multiple language sentences with one identifier only, in other words the technology presented is language-pair independent. Specifically, we indicate that our cosine similarity objective function improves the veloci…
