Roscigno-Monte Pruno: un insediamento indigeno fortificato
No full textIl sito di Roscigno Monte Pruno si presenta come caso studio emblematico per la comprensione delle dinamiche insediative degli abitati definiti da circuiti fortificati nel mondo coloniale dell’Italia meridionale, a partire dal IV sec. a.C. L’insediamento, racchiuso da una poderosa cinta muraria, testimonia nuove forme di occupazione e progettazione degli spazi destinate all’impianto di un nuovo abitato stabile. La trasformazione del circuito difensivo segna dunque un momento significativo di una nuova forma di organizzazione politica e territoriale coincidente con l’arrivo dei Lucani
Il ruolo dell’Architettura nella gestione dei Commons: un’ipotesi per lo “Scugnizzo liberato”.
No full textNel 2013 il Comune di Napoli ha istituito l’Osservatorio sui beni comuni, con quest’atto viene ufficializzata una posizione innovativa, ma anche fortemente controversa, relativa alla gestione di beni di proprietà pubblica o privata da parte di “comunità” che utilizzano questi spazi realizzando un utile sociale. Il numero di Louts del 1994 dal titolo Commons traccia la relazione tra questa questione, di natura economica, politica e sociale e l’architettura. In particolare a Napoli i nove spazi individuati dall’Osservatorio pongono agli architetti nuove domande e, prima tra tutte, come conciliare questa modalità di gestione dal basso, che ha sicuramente il merito di restituire alla comunità luoghi spesso dimenticati e abbandonati, con le esigenze di tutela e conservazione del patrimonio culturale della città. Partendo dal caso dello” scugnizzo liberato” l'intervento proverà a definire un possibile ruolo dell’architettura nel processo di gestione dei Commons
Integrated SW for LEO Satellites End-To-End Performance
No full textOne of the objectives of the “Advanced Techniques for High Data Rate Links for Earth Exploration
Satellites" study, ESA Contract n. 22455/09/NL/JK, is the development of a set of SW to allow the
system designer computing the end-to-end performance of a transmission system in a LEO orbit using
Variable Coding modulation (VCM) techniques.
Under the assumption of an ideal transmission system not including non-linear effects, the SW allow
customizing the main mission parameters according to a user defined scenario; the atmospheric
contribution in terms of both attenuation, sky temperature throughout the whole ground station contact
is computed, enabling a complete “statistical” knowledge of the Es/No curve and consequently an
optimized VCM technique.
In particular, the VCM technique described in this paper was improved with respect to first results
obtained by TAS-I and already presented in [1].

Rehearsal and performance of Brahms' Variations On A Theme By Haydn, Op. 56A
No full textIncludes bibliographical references (leaf 25)The goal of this paper is to document the preparation and performance of Brahms'
Variations on a Theme by Haydn, op. 56a in partial fulfillment of the degree of Master of
Music in Orchestral Conducting. The performance took place on December 7, 2010 on
the campus of California State University, Northridge in the Plaza del Sol Performing
Arts Center. The concert was a regularly scheduled performance for the CSUN
University Orchestra under the direction of Dr. John Roscigno.
This documentation will be presented in three segments: Selection and Research,
Preparation and Rehearsal, and The Performance. Selection and Research will document
how the piece was selected along with the orchestra, and early fmdings about the work.
Preparation and Rehearsal will be organized by individual variation and will cover
private preparation, anticipated problems, and realized rehearsal issues. The Performance
will document what happened during the concert from the perspective of the conductor
and author
Recurrent retroperitoneal solitary fibrous tumor: a case report
No full textBackground: Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm described initially in visceral pleura but can occasionally involve other sites such as the urinary tract. Extrapleural localizations are often indolent but some malignant SFTs have been described. The treatment and the most important prognostic factor for SFT seem to be complete resection of the neoplasm. Case report: We report the 10-year history of a retroperitoneal SFT, which recurred twice after conservative management, and was eventually treated with en bloc resection of the mass, the bladder, and the prostate, and urinary diversion by ileal conduit. To our knowledge, this case has the longest follow-up in the literature. Conclusion: Extrapleural SFTs often have indolent but unpredictable behavior as they can recur even after many years. Some histologic features are associated with the malignancy of these tumors. Complete resection of the neoplasm is the most important prognostic factor. Patients with SFT should be considered for a very long follow-up after the surgery due to the risk of possible late recurrences
Essential oil variability in a collection of Ocimum basilicum L. (basil) cultivars.
No full textBasil is an aromatic plant of great tradition in the Mediterranean area. Its economic importance is growing up determining an expansion of cultivation. This paper evaluated the morphological traits, the chemical profiles and antibacterial activity of 21 cultivars of basil belonging to “Genovese”, “Napoletano” and “Purple basil” types. The cultivars were characterized by different growth rate and morphological traits. The chemical composition of the oils analyzed by GC and GC-MS analysis, supported by the PCA analysis, underlined the strong influence of chemotype. It is noteworthy that estragole, never present in Genovese and purple basil types, occurs in Napoletano type. Anyway it was registered high presence of eugenol, methyl-eugenol and linalool in the majority of cultivars, belonging both to Genovese and Napoletano types. Of great interest resulted the composition of the purple basil “Opal”. All the samples tested exhibited similar antibiotic profiles whit moderate antibacterial activity. The results enhance the importance of determination of essential oil profile in the selection of cultivars characterized by diverse morphological traits and useful for different purposes
VCM throughput analysis for Earth Observation satellites in LEO orbit
No full textSince future systems will also be characterized by the on-board availability of a set of coding and modulation schemes at several spectral efficiencies and different SNR thresholds, the usage of Variable Coding Modulation (VCM) techniques can improve the system performance, by adapting case-by-case the coding/modulation scheme to the actual local atmospheric conditions.
In the frame of the “Advanced Techniques for High Data Rate Links for Earth Exploration Satellites" study, ESA Contract n. 22455/09/NL/JK, a set of SW modules was developed to allow the system designer computing the achievable end-to-end performance of the data downlink architecture of Earth Observation satellite in LEO orbit when using VCM techniques and comparing it versus the achievable figure when Constant Coding Modulation (CCM) is used.
In particular, the SW implements modulation and coding described in the CCSDS standard, pre-distortion techniques, and on-ground algorithms for mitigation of channel contribution to dual-polarization transmission.
Moreover, the SW allow the user selecting the main mission parameters (e.g. orbit, ground station, link availability, non-linear amplifier, on-board RF filters, EIRP etc..) according to its customized scenario
Diagnosis of local recurrence after radical prostatectomy
No full textIn the long-term there is biochemical evidence of recurrent prostate carcinoma in approximate to 40% of patients after radical prostatectomy (RP). Detecting the site of recurrence (local vs distant) is critical for defining the optimum treatment. Pathological and clinical variables, e.g. Gleason score, involvement of seminal vesicles or lymph nodes, margin status at surgery, and especially the timing and pattern of prostate-specific antigen (PSA) recurrence, may help to predict the site of relapse. Transrectal ultrasonography (TRUS) of the prostatic fossa in association with TRUS-guided needle biopsy is considered more sensitive than a digital rectal examination for detecting local recurrence, especially if PSA levels are low. Although it cannot detect minimal tumour mass at very low PSA levels (<1 ng/mL) TRUS biopsy is presently the most sensitive method for detecting local recurrence. Nevertheless, the conclusive role of biopsy of the vesico-urethral anastomosis remains unclear. However, In-111-capromab pendetide scintigraphy and [C-11]-choline tomography (which are better than conventional imaging for detecting metastatic tumour), have low detection rates for local disease and are considered complementary to TRUS in this setting. Patients with a high PSA after RP may be managed with external beam salvage radiotherapy. An initial PSA of < 1 ng/mL, Gleason score < 8 and radiation dose of 66-70 Gy seem to be key factors in determining success. Although a positive TRUS anastomotic biopsy may predict a better outcome after radiation therapy, the need to take a biopsy in the event of PSA failure remains under investigation. The value of salvage radiation to the prostatic bed for PSA-only progression after RP remains in question
Smetana'S The Moldau: Rehearsals And Performance
No full textThis paper will describe the final project completed by the author for the partial fulfillment of the degree of Master of Music in Orchestral Conducting. The orchestra that played under the author's baton was the CSUN Youth Philharmonic Orchestra - a high- level youth orchestra consisting of musicians ranging from ages ten to eighteen - with supervision from Dr. John Roscigno, professor of Orchestral Studies at CSUN. The performance took place on Sunday, March 4, 2018, at the Plaza del Sol Performance Hall on the school campus. The purpose of this project was to rehearse the orchestra and prepare them to perform a piece from the classical repertoire live in concert, with a length of approximately fifteen to twenty minutes. Possible pieces were discussed, and eventually, it was decided that they would play Smetana The Moldau. After long hours of score study, it became obvious that the rehearsal process would be arduous and challenging; not only is the music technically difficult to play, but Smetana writes in the extreme dynamic and range for each instrument, making intonation one of the major issues to deal with in rehearsal. After a brief introduction, the paper is divided into four parts - historical background, selection of movements, the rehearsal process, and performance. Each section will give an insight into this monumental orchestral work, and the main body of the paper will discuss the details of anticipated issues with the orchestra and how they were dealt with in rehearsal. It was a demanding concert, but the brilliant and talented young musicians of this orchestra pulled through and gave a spectacular performance.California State University, Northridge.
