Aiap Design Per, International Graphic Design Week è la grande manifestazione itinerante curata da Aiap, Associazione italiana design della comunicazione visiva*, che nella settima edizione, dopo essersi svolta a Napoli, Bologna, Cagliari, Treviso, Genova e Milano, approda a Roma dove continua a mostrare le sue peculiarità, che si affrontano come in un rinnovato ma pacato duello. Aiap Design Per, International Graphic Design Week – this year at the 7th edition – is the major travelling event organised by Aiap, Italian Association of Visual communication Design* which, after Naples, Bologna, Cagliari, Treviso, Genoa and Milan, finally reaches Rome with all its peculiarities, which confront o…

Current air quality analytics and monitoring: a review.

2014

This review summarizes the different tools and concepts that are commonly applied in air quality monitoring. The monitoring of atmosphere is extremely important as the air quality is an important problem for large communities. Main requirements for analytical devices used for monitoring include a long period of autonomic operation and portability. These instruments, however, are often characterized by poor analytical performance. Monitoring networks are the most common tools used for monitoring, so large-scale monitoring programmes are summarized here. Biomonitoring, as a cheap and convenient alternative to traditional sample collection, is becoming more and more popular, although its main …

Combined target and post-run target strategy for a comprehensive analysis of pesticides in ambient air using liquid chromatography-Orbitrap high reso…

2014

Abstract A comprehensive strategy for the analysis of current airborne pesticides has been developed using liquid chromatography coupled to high resolution mass spectrometry. The methodology includes both quantitative target analysis and post-run target screening analysis. The quantitative method was validated after a previous statistical optimisation of the main factors governing the ion source ionization and a study of the single-stage Orbitrap fragmentation through the HCD cell. The quantitative method presented recoveries ranging from 73 to 116%, with precision (RSD) lower than 20%, for the 35 substances in the scope of the target method. The full-scan accurate mass data were acquired w…

Sampling and analysis of pesticides in ambient air.

2008

Developments in the sampling and determination of pesticides in ambient air have been discussed and data on the occurrence of pesticides in atmosphere have been presented. Developments in active sampling methods were reviewed and the different materials used for trapping pesticides from gas and particulate phases were discussed. Likewise, the use and developments of passive air samplers were reviewed. This article pays special attention to the analysis of pesticides trapped from ambient air, and recapitulate the procedures for extraction, clean-up and determination of these substances. Improvements in sampling procedures, analytical methods and monitoring activities are necessary to advance…

Temperature dependent properties of environmentally important synthetic musks.

2002

Environmental fate determining physical properties including their temperature dependence for five nitro musks and for seven polycyclic musks were estimated. The properties evaluated were vapor pressure in a solid and liquid state (PS and PL), solubility in water (S), Henry's law coefficient (H = PL/S) and log octanol-water partition coefficient (log KOW). Gas chromatography for starting values of vapor pressure estimation and HPLC experiments at 5-20 degrees C for comparison of the theoretical versus experimental solubilities in water were performed. The values of temperature (T) dependence coefficients (Ai and Bi) in equations: log (Property)i = Ai - Bi/T were determined. Values of proper…

Finite-element design sensitivity analysis for non-linear potential problems

1990

Design sensitivity analysis is performed for the finite-element system arising from the discretization of non-linear potential problems using isoparametric Lagrangian elements. The calculated sensitivity formulae are given in a simple matrix form. Applications to the design of electromagnets and airfoils are given.

Romanization of Funerary Rituals in Oretania: The Tomb 1 of the Cemetery of the Cerro de las Cabezas (Valdepeñas, Ciudad Real, Spain)

2017

La correcta aplicación de un procedimiento de prevención de impactos y protección al patrimonio arqueológico, desarrollado con motivo de la implantación de una línea eléctrica de alta tensión, permitió en 2013 el hallazgo de una necrópolis junto al Cerro de las Cabezas (Valdepeñas, Ciudad Real). Hasta el momento se desconocía la localización del área funeraria de este gran oppidum. Las catorce tumbas documentadas durante esta breve intervención (catorce días de trabajo) corresponden a los enterramientos de cremaciones en urnas, con piezas de ajuar asociadas como fusayolas, fíbulas, armas y recipientes cerámicos. Se presenta el estudio ceramológico de la Tumba 1; la única de entre las excava…

Aureliano in Cisalpina. I riflessi delle invasioni alamanniche nelle testimonianze archeologiche

2006

Le scarse testimonianze archeologiche risalenti al periodo delle invasioni alamanniche nel Nord della penisola italica rivelano, a un'analisi attenta, una situazione meno catastrofica di quella che è stata spesso descritta dagli studiosi che si sono occupati di quelle vicende.

Classification of vegetable oils according to their botanical origin using amino acid profiles established by direct infusion mass spectrometry.

2007

Amino acid profiles, established by direct infusion mass spectrometry, have been used to classify vegetable oils according to their botanical origin. The proteins present in hazelnut, sunflower, corn, soybean, olive, avocado, peanut and grapeseed oils were precipitated with acetone, and the residue was hydrolyzed in acid medium, diluted in a hydrochloric acid/ethanol mixture, and infused into the mass spectrometer. The spectra of the hydrolyzed protein extracts showed [M+H]+ ions of the following amino acids: glycine, alanine, serine, proline, valine, threonine, cysteine, isoleucine + leucine, aspartic acid, lysine, glutamic acid, methionine, histidine, phenylalanine, arginine and tyrosine.…
