Business Models and Economic Approaches for Recovering Energy from Wastewater and Fecal Sludge
2015
Universal access to water, sanitation and energy services are key challenges in low income countries. The conventional model of providing water, sanitation and waste disposal as a social service is no longer viable because national authorities lack financial and human resources for operation and maintenance and for addressing the sanitation needs locally. Human excreta and wastewater represent resources that can be used to generate new income and support livelihoods through use as a source of energy. The reduction, removal and reuse of wastes must become financially feasible and economically profitable and yield high returns. This requires innovative and sustainable business models and fina…
Inflammation and sarcopenia: A systematic review and meta-analysis
2017
Inflammatory cytokines have been shown to prompt muscle wasting, ultimately stimulating protein catabolism and suppressing muscle synthesis. However, the possible association between inflammatory parameters and sarcopenia is poorly understood. We therefore aimed to summarize the current evidence about this topic with a meta-analysis of studies reporting serum inflammatory parameters in patients with sarcopenia vs. people without sarcopenia (controls). An electronic PubMed and Scopus search through to 09/01/2016 and meta-analysis of cross-sectional studies comparing serum levels of inflammatory cytokines between patients with sarcopenia and controls was made, calculating random-effects stand…
5G Functional Architecture and Signaling Enhancements to Support Path Management for eV2X
2019
Enhanced vehicle-to-everything (eV2X) communication is one of the most challenging use cases that the fifth generation (5G) of cellular mobile communications must address. In particular, eV2X includes some 5G vehicular applications targeting fully autonomous driving which require ultra-high reliability. The usual approach to providing vehicular communication based on single-connectivity transmission, for instance, through the direct link between vehicles (PC5 interface), often fails at guaranteeing the required reliability. To solve such a problem, in this paper, we consider a scheme where the radio path followed by eV2X messages can be proactively and dynamically configured to either trans…
Biochemistry and molecular biology techniques for person characterization
2008
Using the traditional serological tests and the most novel techniques for DNA fingerprinting, forensic scientists scan different traits that vary from person to person and use the data to include or exclude suspects based on matching with the evidence obtained in a criminal case. Although the forensic application of these methods is well known, the procedures and techniques used to obtain these results are not so well studied. Here, we report a laboratory exercise aimed to familiarize the students in several of the methods and markers employed for people individualization. With this exercise, students have to characterize themselves and an unknown sample according to the following character…
Sepsis due to Streptococcus pneumoniae associated with secondary hemophagocytic lymphohistiocytosis in a splenectomized patient for spherocytosis
2017
Abstract Rationale: Hemophagocytic lymphohistiocytosis (HLH) is a syndrome that is characterized by an inappropriate hyperinflammatory immune response – primary, as a consequence of a genetic defect of NK cells and cytotoxic T lymphocytes or – secondary, in the progression of infections, rheumatic or autoimmune diseases, malignancies or metabolic diseases. Patient concerns: We present the case of a secondary HLH due to Streptococcus pneumoniae infection in a splenectomised patient for spherocytosis, a 37-year-old patient who was splenectomised in childhood for spherocytosis, without immuneprophylaxis induced by antipneumococcal vaccine. Outcomes: He developed a severe pneumococcal sepsis as…
Molecular Typing Reveals Frequent Clustering among Human Isolates of Listeria monocytogenes in Italy
2009
In Italy, the annual incidence of reported cases of listeriosis amounts in recent years (2004 to 2006) to 0.8 cases per million inhabitants. Our study is a subtyping analysis by serotyping, ribotyping, and pulsed-field gel electrophoresis analysis of 44 human isolates from apparently sporadic cases of infection in the Lombardy region and in the Province of Florence, Italy, in the years 1996 to 2007. Based on the results of the different subtyping methods, 10 occasions were detected when strains of L. monocytogenes with the same subtype were isolated from more than one listeriosis case. A total of 28 (66.7%) out of 44 isolates were attributed to molecular subtype clusters. Our data support t…
A Scatter Search Algorithm for the Split Delivery Vehicle Routing Problem
2008
In this chapter we present a metaheuristic procedure constructed for the special case of the Vehicle Routing Problem in which the demands of clients can be split, i.e., any client can be serviced by more than one vehicle. The proposed algorithm, based on the scatter search methodology, produces a feasible solution using the minimum number of vehicles. The quality of the obtained results is comparable to the best results known up to date on a set of instances previously published in the literature.
A New Metaheuristic for the Vehicle Routing Problem with Split Demands
2007
In this paper we present a metaheuristic procedure constructed for the special case of the Vehicle Routing Problem in which the demands of the clients can be split, i.e., any client can be serviced by more than one vehicle. The proposed algorithm, based on the scatter search methodology, produces a feasible solution using the minimum number of vehicles. The results obtained compare with the best results known up to date on a set of instances previously published in the literature.
ASSOCIATION BETWEEN THE POLYMORPHISM AT CASEIN LOCI AND MILK FATTY ACID COMPOSITION IN GIRGENTANA GOATS
2013
composition is an important trait for the goat dairy industry because of its influence on cheese yield and the organoleptic properties of dairy products (Chilliard et al., 2003). Goat milk is particularly rich in saturated fatty acids (SFA) whereas monounsaturated (MUFA) and polyunsaturated (PUFA) FA are less abundant (Fontecha et al., 2000).The aim of this work was to provide new data to better understand the influence of polymorphism at casein loci on fatty acid profile in Girgentana goat milk. One hundred lactating Girgentana goats, homogeneous for milk production, days of lactation, body weight and diet were used. The procedure was developed using individual raw milk samples, collected …
Haplotypes of Single Nucleotide Polymorphisms (SNPs) in casein loci of Girgentana goats explain isoelectrofocusing results.
2006
Goat milk, cheese and yoghurt offer an alternative to cow milk products. In Sicily one of the important goat breeds reared is the Girgentana. Traditionally the milk from Girgentana goats was used for nourishment of infants and elderly. Recently, the Girgentana breed has been in decline. This of concern, as the Girgentana may carry unique milk protein genetic variants. If health benefits of Girgentana goat milk is proven, then increasing production from this population will be of great interest. The most abundant proteins in goat milk, as in other milks, are the caseins, αS1-, β-, αS2- and κ-casein, coded by the loci CSN1S1, CSN2, CSN1S2 and CSN3 respectively. In other goat breeds, the casei…
