Real-time control strategy for nitrogen removal via nitrite in a SHARON reactor using pH and ORP sensors
2012
This paper presents a real-time control strategy for nitrogen removal via nitrite in a continuous flow SHARON reactor using on-line available and industrially feasible sensors (pH and ORP). The developed control strategy optimizes the length of aerobic and anoxic phases as well as the external carbon source addition. This strategy, implemented in a laboratory-scale SHARON reactor fed with synthetic wastewater and real dewatering sludge supernatant, was able to cope with step variations in influent flow rate and ammonium concentration. The main advantages of this control strategy over the traditional operation mode with fixed carbon source dosification and fixed length cycle operation were: …
Validity of long-term and short-term recall of occupational sitting time in Finnish and Chinese office workers.
2020
Abstract Background As sedentary behavior is a global health issue, there is a need for methods of self-reported sitting assessment. The accuracy and reliability of these methods should also be tested in various populations and different cultural contexts. This study examined the validity of long-term and short-term recall of occupational sitting time in Finnish and Chinese subgroups. Methods Two cohort groups of office-based workers (58.6% female, age range 22–67 years) participated: a Finnish group (FIN, n = 34) and a Chinese group (CHI, n = 36). Long-term (past 3-month sitting) and short-term (daily sitting assessed on 5 consecutive days) single-item measures were used to assess self-r…
Menores, víctimas directas de la violencia de género
2016
La violencia de género se suele ejercer en el ámbito privado o familiar, motivo por el cual, los hijos pueden considerarse tanto víctimas directas por sufrir violencia física o psicológica, como indirectas al ser testigos de la violencia ejercida sobre sus progenitoras por parte de la persona vinculada afectivamente. En los últimos años, y a pesar de los esfuerzos institucionales en aras de proteger a los menores, la violencia ejercida sobre los mismos ha elevado a 41 el número de víctimas mortales en España desde 2008 hasta septiembre de 2015. El objetivo del presente trabajo es divulgar la cifra de menores fallecidos víctimas de violencia de género, así como elaborar un posible perfil vic…
Tandem cross enyne metathesis (CEYM)–intramolecular Diels–Alder reaction (IMDAR). An easy entry to linear bicyclic scaffolds
2015
A new tandem cross enyne metathesis (CEYM)–intramolecular Diels–Alder reaction (IMDAR) has been carried out. It involves conjugated ketones, esters or amides bearing a remote olefin and aromatic alkynes as the starting materials. The overall process enables the preparation of a small family of linear bicyclic scaffolds in a very simple manner with moderate to good levels of diastereoselectivity. This methodology constitutes one of the few examples that employ olefins differently than ethylene in tandem CEYM–IMDAR protocols.
C18 alkyl-modified silica: A suitable tool for olive biophenol green extraction
2017
Abstract A clean and straightforward methodology to assess the value of olive mill wastewater (OMWW) samples as well as to obtain biophenol-rich oils that can find employment in a variety of cosmetic, nutraceutical and pharmaceutical products is described. The method employs chromatographic spherical organosilica microparticles, coupled to advanced analytical techniques. OMWW samples obtained in Sicily from two different organically grown cultivars during the exceptional 2015/2016 olive oil season were analyzed, leading us to establish the conditions for optimal extraction of hydroxytyrosol and tyrosol.
Development of Methods for Olive Oil Quality Evaluation
2012
In this work, a simple and quick method for olive oil classification according to its quality grades, based on direct infusion ESI–MS and LDA, was developed. Moreover, mixtures of EVOO and VOO, and binary mixtures of these two oils with olive oils of lower quality grade have been also evaluated using this methodology and MLR and PLS data treatment.
A Circular Economy Approach to Fish Oil Extraction
2019
Fish oil rich in polyunsaturated omega-3 fatty acids is extracted in high yield from anchovy filleting waste using d-limonene as green biosolvent in a simple solid-liquid extraction performed by mechanically stirring and maceration followed by limonene removal via evaporation under reduced pressure. As limonene is renewably obtained from waste orange peel, this method closes the materials cycle and establishes a circular economy process to obtain high quality fish oil from biowaste available worldwide in several million t/year amount. Significant economic, social and environmental benefits are anticipated.
Potential impact of a nonavalent HPV vaccine on HPV related low-and high-grade cervical intraepithelial lesions: A referral hospital-based study in S…
2017
ABSTRACT While bivalent and quadrivalent HPV vaccines have been used for about 10 years, a nonavalent vaccine against HPV types 6/11/16/18/31/33/45/52 and 58 has been recently approved by FDA and EMA and is now commercially available. The objective of our study was to evaluate the potential impact of the nonavalent vaccine on HPV infection and related low- and high-grade squamous intraepithelial lesions (LSIL, HSIL), compared to the impact of the quadrivalent vaccine, in a female population living in Sicily (Italy). Low estimates of HPV vaccine impact were calculated as prevalence of HPV 6/11/16/18/31/33/45/52 and 58 genotypes, alone or in association, but excluding presence of other HPV ty…

Molecular markers and biological targeted therapies in metastatic colorectal cancer: expert opinion and recommendations derived from the 11th ESMO/Wo…
2010
The article summarizes the expert discussion and recommendations on the use of molecular markers and of biological targeted therapies in metastatic colorectal cancer (mCRC), as well as a proposed treatment decision strategy for mCRC treatment. The meeting was conducted during the 11th ESMO/World Gastrointestinal Cancer Congress (WGICC) in Barcelona in June 2009. The manuscript describes the outcome of an expert discussion leading to an expert recommendation. The increasing knowledge on clinical and molecular markers and the availability of biological targeted therapies have major implications in the optimal management in mCRC. 21 Suppl 6 vi1 10
