In-Situ Testing of a Cement-Stabilized Metallurgical Residue
No full textA large deposit of cement-stabilized jarosite was investigated by means of DMT as well as other in-situ tests (e.g. CPTu) and laboratory tests on core and block samples retrieved from the deposit. The material of dominant silt size, contains no silicates, has a large porosity and a relatively high (11%) cement content that results in a significant –but fragile- mechanical improvement. The deposit was built without resource to systematic compaction and the in-situ tests reveal significant inhomogeneities despite the industrial origin of the material. This paper examines the in situ test results focusing on basic index and state properties of the residue. The performance of correlations and interpretation methods well proven in conventional soils (i.e. silicate-based) is examined in detail. Particular attention is given to cement-induced apparent overconsolidation. The classical KD based correlation for clay appears to perform relatively well
Editorial: Ruminant grazing behavior: A tool to improve product quality and ecosystem services.
No full textABSTRACT.- This Research Topic presents a series of original research and one review article that reveals the latest approaches to ruminant grazing behavior management associated with product quality and traceability. This collection embodies 12 original articles from eight countries, including Europe (Mediterranean, continental, and alpine regions) and North and South America. Articles were mainly focused on three axes: (i). pasture and grazing management and its relationship with ecosystem services, (ii). effect feeding behavior on animal's products, and (iii). genetics and grazing behavior.Copyright © 2021 Devincenzi, Coppa and Cabiddu
SDMT-based deep excavation design
No full textThis communication presents some results from a case history in Barcelona involving a large cut-and-cover railway tunnel requiring a deep excavation (depth > 20 m). Prediction of excavation-induced movements was necessary to assess third-party risk. A numerical model was set-up for the prediction and extrapolation of monitoring results obtained at a trial instrumented section. Monitoring results are here compared with model predictions relying mostly on results from seismic dilatometer tests (SDMT). Parameters deduced from dilatometric measures are employed to characterise the different soil layers using the Hardening soil model implemented in PLAXIS. Then, the extra information provided by the seismic data is fed into a nonlinear elastic-plastic model, using a well known stiffness-strain degradation curve. Results from both simulations are here compared with the monitoring data

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Amines Protect Invitro the Celiac Small-intestine From the Damaging Activity of Gliadin Peptides
No full textProteins and peptides responsible for the celiac small intestinal lesion inhibit both the enterocyte recovery of in vitro cultured flat celiac mucosa and the in vitro development of fetal rat intestine, They also agglutinate K 562 (S) cells. Using these three in vitro systems (cultured human celiac and rat fetal intestine and cell agglutination), it is shown that several small-molecular-weight amines, mostly the polyamines spermidine and spermine, prevent and reverse K 562 (S) cell agglutination induced by gliadin peptides, whereas they do not prevent cell agglutination induced by concanavalin A and wheat germ agglutinine Some of these amines also protected in vitro developing fetal rat intestine and fiat celiac mucosa from the damaging effect of gliadin peptides. This protective effect may be related to the trophic activity exerted by amines on the intestine and/or the effect of amines on the functions of intestinal brush border or intracellular membranes involved in the intestinal handling of gliadins
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
Get PDFFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
I bisogni del paziente con patologia oncologica e le risposte negli statuti di servizi sanitari dedicati e associazioni
No full textLa ricerca indaga i bisogni espressi da
persone malate di cancro nell’Area Vasta Nord dell’Emilia
Romagna e quali, tra questi bisogni, sono anche obiettivi
dei servizi sanitari e delle associazioni dedicati alla malattia
oncologica. Metodo. Sono stati intervistati 22 pazienti
oncologici (12 F e 10 M; età media = 55.3±10.7) e sono stati
analizzati 25 statuti di associazioni e 17 Carte dei Servizi
Sanitari. Risultati. I bisogni fondamentali dei malati oncologici
sono raramente di natura economica, legale, materiale
e molto più spesso concernono l’area medica e psicologica
(es. bisogno di supporto/sostegno psicologico, di cure
mediche e di uguaglianza al trattamento, di continuità di
cure in ospedale e a domicilio e di formazione su diagnosi
e trattamenti). I Servizi Sanitari pongono attenzione al soddisfacimento
dei bisogni di autodeterminazione, di dignità e
rispetto della persona, di informazione su diagnosi e trattamenti
e di sostegno psicologico. Le associazioni offrono aiuto
attraverso la promozione di attività socializzanti (bisogno
di aggregazione e compagnia) e sostegno sia al malato
che ai suoi familiari. Esse si pongono anche come collegamento
nella continuità di cura fra ospedale e domicilio. Conclusioni.
Se da un lato c’è attenzione da parte dei servizi sanitari
e delle associazioni alla risposta a molti bisogni fondamentali,
alcuni di essi rimangono insoddisfatti ed altri non
sono adeguatamente considerati (es. bisogno di ritornare alla
propria quotidianità). L’offerta orientata al soddisfacimento
di questi bisogni potrebbe essere quindi potenziata anche
attraverso una rete di sinergiche collaborazioni tra servizi
sanitari, cittadinanza ed associazioni
