Individual and population-level responses to ocean acidification

2016

Ocean acidification is predicted to have detrimental effects on many marine organisms and ecological processes. Despite growing evidence for direct impacts on specific species, few studies have simultaneously considered the effects of ocean acidification on individuals (e.g. consequences for energy budgets and resource partitioning) and population level demographic processes. Here we show that ocean acidification increases energetic demands on gastropods resulting in altered energy allocation, i.e. reduced shell size but increased body mass. When scaled up to the population level, long-term exposure to ocean acidification altered population demography, with evidence of a reduction in the pr…

Application of hybrid linear ion trap-high resolution mass spectrometry to the analysis of mycotoxins in beer

2011

This paper reports the application of liquid chromatography electrospray ionization ion trap-orbitrap mass spectrometry for the determination of 18 mycotoxins (aflatoxins, fumonisins, trichothecenes, ochratoxin A, sterogmatocystin, beauvaricin, zearalenone and zearalenol) in beer. The extraction procedure was carried out by solid phase extraction (SPE): SPE columns were conditioned with acetonitrile/methanol and water. Beer was loaded onto the column which was washed with water. In these conditions, the recoveries were more than 65% and the relative standard deviation (RSD) were below 18%. The lowest limits of quantification (LLOQ) ranged from 9 to 155 ng ml(-1). Matrix-matched calibration …

New method for determination of ochratoxin A in beer using zinc acetate and solid-phase extraction silica cartridges

2006

Abstract A new method for the determination of ochratoxin A (OTA) in beer has been developed. The new method has been compared with a reference method currently accepted as AOAC official first action. The limits of detection and quantification of the proposed method were 0.0008 and 0.0025 ng/ml, respectively, while they were 0.0025 and 0.0075 ng/ml, respectively, in the AOAC method used as reference. The recovery levels in the 0.025–0.40 ng OTA/ml spiking range for the proposed and the reference methods were 80.6–87.6% and 78.2–83.8%, respectively. The relative standard deviations of recoveries were 2.6–7.5% for the proposed method and 0.7–6.1% for the reference method. Passing and Bablok r…

Multicenter investigation of 1,036 subjects using a standardized method for the assessment of olfactory function combining tests of odor identificati…

2000

“Sniffin’ Sticks” is a test of nasal chemosensory performance that is based on penlike odor-dispensing devices. It is comprised of three tests of olfactory function: tests for odor threshold, discrimination and identification. Previous work has already established its test-retest reliability and validity in comparison to established measures of olfactory sensitivity. The results of this test are presented as a composite TDI score – i.e., the sum of results obtained for threshold, discrimination and identification measures. The present multicenter investigation aimed at providing normative values in relation to different age groups. To this end, 966 patients were investigated in 11 centers. …

Cultural institutions as agents of urban and community regeneration in the (post-)pandemic city. The case of the «Laboratorio Zen Insieme» in Palermo

2022

Although all cities in the world have been affected by the COVID-19 pandemic, its impacts on the territories, yet to be understood, are unevenly distributed, revealing extremely varied imbalances depending on the places. However, it is clear that the virus and its variants have aggravated pre-existing socio-spatial inequalities, creating new ones and bringing attention back to those implications between space, planning, public health and citizenship that are at the origins of contemporary urbanism. In a reference framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized social contexts and g…

Olsen 2018Settore ICAR/21 - UrbanisticaSettore M-GGR/01 - GeografiaSacco and Blessi 2009). In the current (post-) pandemic context and through the lens of a southern European perspective the purpose of this article is to critically reflect about the role of culture as possible vehicle of urban and community regeneration. In particular we will focus on the activities of the no profit organization «Laboratorio Zen Insieme» in ZEN2 one of the last large popular and peripheral neighborhoods built in Palermo at the end of 80s in order to explore and understand how cultural practices work as agent of urban and social transformation capable of addressing emerging issues especially in the pandemic scenario we are experiencing. Thecasestudy has been conducted through analysis of documents participative observations (Honer and Hitzler 2015) and qualitative in-depth interviews with key actors involved in the conception organization and management of the activities carried out by Laboratorio Zen Insieme with representatives of local institutions and non-formal conversations with participants of the workshops heldin the neighborhood. The experience we narrate finds that cultural practices have re-conceptualized their design and functions as strategies of urban and community regeneration and at the same time have contributed to answer to emergent issues in developing proximity and local based strategies facing up to problems inherent civil rights educationalpoverty socio-spatial justice and have changed the image and identity of urban places they inhabit.In this sense the research provides a framework for development of strategies and legitimization for cultural practices and a point of discussionabouttheirrolein urban development.Although all cities in the world have been affected by the COVID-19 pandemic its impacts on the territories yet to be understood are unevenly distributed revealing extremely varied imbalances depending on the places.

In a reference framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized social contexts and groups a response to the new social and individual needs has been offered by cultural institutions that play a role of territorial agency often independently or in the absence of political institutions. Far from the idea of entertainment and divertissement it is in fact increasingly clear how the practices of cultural innovation experimenting with various forms of action and participation can in some cases play a fundamental role in the processes of social cohesion and community building representing an antidote to the worsening of the phenomena of marginalization and socio-spatial inequalities within cities and territories (Colantonio and Dixon 2011

Communication: Restoring full size extensivity in internally contracted multireference coupled cluster theory.

2012

The reason for the lack of size extensivity in the valence space in current implementations of internally contracted multireference coupled cluster theories is the procedure used to eliminate redundant components from the cluster operator. We present a simple way to restore full size extensivity by performing this critical step in a basis of excitation operators that are normal ordered with respect to the multiconfigurational reference function.

Effects of Neuromuscular Electrical Stimulation Training on Endurance Performance

2016

Various electrical stimulation modalities are used as adjuvants to conventional training and rehabilitation programs to increase bodily function or to reduce symptoms, such as pain. One of these modalities, neuromuscular electrical stimulation (NMES), commonly refers to the transcutaneous application of electrical currents to a target muscle group with the objective to depolarize motor neurons and consequently elicit skeletal muscle contractions of substantial intensity (usually ranging from 10 to 60% of the maximal voluntary contraction). Because NMES can generate considerable muscle tension, it is frequently used as a strength training technique for healthy adults and athletes, but also a…

A Computational Study on Temperature Variations in MRgFUS Treatments Using PRF Thermometry Techniques and Optical Probes

2021

Structural and metabolic imaging are fundamental for diagnosis, treatment and follow-up in oncology. Beyond the well-established diagnostic imaging applications, ultrasounds are currently emerging in the clinical practice as a noninvasive technology for therapy. Indeed, the sound waves can be used to increase the temperature inside the target solid tumors, leading to apoptosis or necrosis of neoplastic tissues. The Magnetic resonance-guided focused ultrasound surgery (MRgFUS) technology represents a valid application of this ultrasound property, mainly used in oncology and neurology. In this paper
