Development of multi-layer crystal detector and related front end electronics
No full textA crystal (diamond) particle detector has been developed and tested, whose constitute elements are a multi-layer polycrystalline diamond and a pick-up system capable of collecting in parallel the charge produced in the layers. The charge is read with a charge-to-voltage amplifier (5–6 mV/fC) realized with bipolar junction transistors in order to minimize the effect of the detector capacitance. The tests performed with cosmic rays and at the beam test facility of Frascati with 500 MeV electrons in single electron mode operation have shown that a detector with 4–5 layers of 250 μm thickness each and 9 mm2 active area exhibits an upper limit of 150 ps time resolution for minimum ionizing particles at an operating voltage of about 350 V
Hydroelectrolytic Disorders
No full textMaintaining body fluid and electrolyte balance is of paramount importance for normal functioning. Any alteration in this balance falls under the definition of “hydroelectrolytic disorders.”
Fever of Unknown Origin
No full textThe term fever of unknown origin (FUO) indicates febrile illnesses with a temperature above 38.3 °C for which an etiological diagnosis has not yet been formulated after 3 days of hospitalization or after three specialist visits. Certainly, in this context, the clinical laboratory provides essential elements to guide the etiological diagnosis
Biomarkers of Inflammation
No full textPhlogosis, or inflammation, is an innate defense mechanism that our organism activates in response to various stimuli. Phlogosis is characterized by chemical mediators that play a fundamental role in various phases, from initiation to development and extinction or maintenance. Phlogosis markers are generally nonspecific because their levels increase during inflammation due to different causes. Therefore, their evaluation provides a general picture of the patient’s clinical condition
Diabetes Mellitus: From Definition to Therapy
No full textThis chapter provides an in-depth description of the various types of diabetes mellitus, from the definition to the classification, epidemiology, pathogenesis, diagnosis, monitoring, and therapy. In addition, a description of glucose metabolism will be provided to facilitate the understanding of the diabetic disease
Metabolic Syndrome
No full textMetabolic syndrome is a biochemical-clinical condition characterized by resistance to insulin action associated with a proinflammatory and prothrombotic state. It represents an important cardiovascular risk factor with a constantly increasing incidence in the general population; therefore, its early detection is fundamental to implement preventive interventions. This chapter describes the main characteristics of metabolic syndrome and the criteria used to diagnose it
Valutazione bio-agronomica di biotipi siciliani di gramigna (Cynodon dactylon L. Pers.) per la realizzazione di tappeti erbosi in ambiente mediterraneo
No full textIl lavoro ha riguardato la valutazione della variabilità esistente all’interno di una collezione di gramigna siciliana (Cynodon dactylon L.) con lo scopo di identificare quelle accessioni con caratteristiche di pregio per la realizzazione di tappeti erbosi.
Sono stati esaminati 40 biotipi, provenienti da aree della Sicilia con differenti caratteristiche pedoclimatiche e vegetazionali. I rilievi effettuati hanno riguardato i principali caratteri biometrici e qualitativi del tappeto erboso di gramigna.
Al fine di raggruppare i biotipi con caratteristiche simili, sulla base dei parametri allo studio, è stata effettuata la Hierarchical cluster analysis, mediante la distanza euclidea quadratica, utilizzando il software SPSS 16.0.
I risultati dell’analisi, visualizzati graficamente mediante dendrogramma, hanno permesso di rilevare cinque gruppi omogenei.
I cluster III, IV e V hanno presentato le migliori performance biometriche e qualitative, risultando suscettibili di valorizzazione ai fini dell’impiego sportivo del tappeto erboso
