FORENSIC MICROBIOLOGY: A CASE SERIES ANALYSIS
2019
The importance of microbial colonization of human organs in a living body has long been assessed. What still remains unclear are the microbial changes occurring after death, thus leading to the advent of a relatively novel field of research called “Postmortem microbiology”. It is applied to several forensic fields such as post-mortem interval assessment and cause of death determination. In this contest, a major limit is thus represented by the correct interpretation of the microbial data and by the actual lack of standard procedures. Here we propose a standard operative protocol in order to avoid false positives given by contamination (the main problem), post-mortem translocation and agonal…
Cetuximab +/- chemotherapy enhances dendritic cell-mediated phagocytosis of colon cancer cells and ignites a highly efficient colon cancer antigen-sp…
2012
Cetuximab is a human/mouse chimeric IgG1 monoclonal antibody (mAb) to epidermal growth factor receptor, approved for colorectal carcinoma treatment in combination with chemotherapy. The immune-mediated effects elicited by its human fraction of crystallization moiety might critically contribute to the overall anti-tumor effectiveness of the antibody. We therefore investigated cetuximab ability to promote colon cancer cell opsonization and phagocytosis by human dendritic cells (DCs) that are subsequently engaged in antigen-cross presentation to cytotoxic T-lymphocyte (CTL) precursors. Human colon cancer cell lines were evaluated for susceptibility to DC-mediated phagocytosis before and after …
Initial approaches in benchmarking and round robin testing for proton exchange membrane water electrolyzers
2019
Abstract As ever-increasing amounts of renewable electricity enter the energy supply mix on a regional, national and international basis, greater emphasis is being placed on energy conversion and storage technologies to deal with the oscillations, excess and lack of electricity. Hydrogen generation via proton exchange membrane water electrolysis (PEMWE) is one technology that offers a pathway to store large amounts of electricity in the form of hydrogen. The challenges to widespread adoption of PEM water electrolyzers lie in their high capital and operating costs which both need to be reduced through R&D. An evaluation of reported PEMWE performance data in the literature reveals that there …
Dieci gesti-barriera per le città aumentate del Neoantropocene
2022
Le città non sono solo luoghi dell'abitare. Esse sono anche potenti dispositivi creativi per attivare il diverso presente ed esplorare il futuro possibile se consentono una vita di comunità che costruisca relazioni feconde, generi sinapsi fertili, produca nuove economie e acceleri l'innovazione. Il contributo fornisce strumenti e metodi utili alla definizione della città aumentata come fattore abilitante del cambiamento verso il Neoantropocene.
Improving quality in clinical placement studies in nursing homes (QUALinCLINstud):the study protocol of a participatory mixed methods multiple case s…
2020
IntroductionImproved quality in clinical supervision and assessment of student nurses in nursing home clinical placements is vitally important to effective recruitment and preparation for this healthcare sector. Knowledge regarding supervision and assessment practices within these settings is limited. Also, knowledge of evolving e-learning tools on the quality and effectiveness of these educational practices seems to be absent.Methods and analysisThe aim of the “Improving quality in clinical placement studies in nursing homes” (QUALinCLINstud) study is to develop and evaluate how a web-based programme can optimise supervision, assessment and learning during nursing home placements. The stud…
A High speed data link optimization for digitalized transfer to processing FPGA
2021
State-of-the-art arrays of detectors, that require digital processing, may have a sizeable number of digitalized signal links. This is the case in several experimental nuclear physics instruments. Moreover, the data rate of the sampled signals, defined primary by the signal bandwidth of the individual detectors, may not exhaust the capabilities of a single FPGA transceiver input. The preprocessing is usually carried out in a modern FPGA with transceiver data rate capabilities over 10Gbps. Moreover, cost effective FPGA have a limited number of transceivers for given FPGA processing capabilities. The investigation of a cost-effective and efficient solution to the mismatch between both data ra…
Specific protocol (SENSLOG) over TCP/IP for sensors applications
2005
The objective is to obtain an embedded system using a microcontroller that will communicate with other devices over a specific protocol (SENSLOG) over TCP/IP for sensors applications. The protocol has been designed for this application, but the commands are generic. They can be used for any type of sensing. We must take into account that this program will run in a microcontroller and it will communicate with another program running in a PC. The protocol is based on commands, like SMTP. From the PC we will send commands to the microcontroller to do specific tasks, and if it is necessary, the microcontroller will answer to the PC. Some of the functions designed for this protocol are: to contr…
Col : A Data Collection Protocol for Vanet
2012
International audience; In this paper, we present a protocol to collect data within a vehicular ad hoc network (VANET). In spite of the intrinsic dynamic of such network, our protocol simultaneously offers three relevant properties: (1) It allows any vehicle to collect data beyond its direct neighborhood (i.e., vehicles within direct communication range) using vehicle-to-vehicle communications only (i.e., the infrastructure is not required); (2) It tolerates possible network partitions; (3) It works on demand and stops when the data collection is achieved. To the best of our knowledge, this is the first collect protocol having these three characteristics. All that is chiefly obtained thanks…
LPV model identification for gain scheduling control: An application to rotating stall and surge control problem
2006
Abstract We approach the problem of identifying a nonlinear plant by parameterizing its dynamics as a linear parameter varying (LPV) model. The system under consideration is the Moore–Greitzer model which captures surge and stall phenomena in compressors. The control task is formulated as a problem of output regulation at various set points (stable and unstable) of the system under inputs and states constraints. We assume that inputs, outputs and scheduling parameters are measurable. It is worth pointing out that the adopted technique allows for identification of an LPV model's coefficients without the requirements of slow variations amongst set points. An example of combined identification…
Decentralized classification in societies of autonomous and heterogenous robots
2011
This paper addresses the classification problem for a set of autonomous robots that interact with each other. The objective is to classify agents that “behave” in “different way”, due to their own physical dynamics or to the interaction protocol they are obeying to, as belonging to different “species”. This paper describes a technique that allows a decentralized classification system to be built in a systematic way, once the hybrid models describing the behavior of the different species are given. This technique is based on a decentralized identification mechanism, by which every agent classifies its neighbors using only local information. By endowing every agent with such a local classifie…
