Abstract:
Abstract Background Compared to pneumatically controlled pressure support (PSP), neurally adjusted ventilatory assist (NAVA) was proved to improve patient–ventilator interactions, while not affecting comfort, diaphragm electrical activity (EAdi), and arterial blood gases (ABGs). This study compares neurally controlled pressure support (PSN) with PSP and NAVA, delivered through two different helmets, in hypoxemic patients receiving noninvasive ventilation for prevention of extubation failure. Methods Fifteen patients underwent three (PSP, NAVA, and PSN) 30-min trials in random order with both helmets. Positive end-expiratory pressure was always set at 10 cm H2O. In PSP, the inspiratory support was set at 10 cm H2O above positive end-expiratory pressure. NAVA was adjusted to match peak EAdi (EAdipeak) during PSP. In PSN, the NAVA level was set at maximum matching the pressure delivered during PSP by limiting the upper pressure. The authors assessed patient comfort, EAdipeak, rates of pressurization (i.e., airway pressure-time product [PTP] of the first 300 and 500 ms after the initiation of patient effort, indexed to the ideal pressure–time products), and measured ABGs. Results PSN significantly increased comfort to (median [25 to 75% interquartile range]) 8 [7 to 8] and 9 [8 to 9] with standard and new helmets, respectively, as opposed to both PSP (5 [5 to 6] and 7 [6 to 7]) and NAVA (6 [5 to 7] and 7 [6 to 8]; P < 0.01 for all comparisons). Regardless of the interface, PSN also decreased EAdipeak (P < 0.01), while increasing PTP of the first 300 ms from the onset of patient effort, indexed to the ideal PTP (P < 0.01) and PTP of the first 500 ms from the onset of patient effort, indexed to the ideal PTP (P < 0.001). ABGs were not different among trials. Conclusions When delivering noninvasive ventilation by helmet, compared to PSP and NAVA, PSN improves comfort and patient–ventilator interactions, while not ABGs. (Anesthesiology 2016; 125:1181-9)

Abstract:
ObjectivesTo explore the role of the available midbrain-based MRI morphometric assessments in (1) differentiating among progressive supranuclear palsy (PSP) subtypes (PSP Richardson’s syndrome (PSP-RS), PSP with predominant parkinsonism (PSP-P) and the other variant syndromes of PSP (vPSP)), and (2) supporting the diagnosis of PSP subtypes compared with Parkinson’s disease (PD) and healthy controls (HC).MethodsSeventy-eight patients with PSP (38 PSP-RS, 21 PSP-P and 19 vPSP), 35 PD and 38 HC were included in the present analysis. Available midbrain-based MRI morphometric assessments were calculated for all participants.ResultsCurrent MRI midbrain-based assessments do not display an adequate sensitivity and specificity profile in differentiating PSP subtypes. On the other hand, we confirmed MR Parkinsonism Index (MRPI) and pons area to midbrain area ratio (P/M) have adequate diagnostic value to support PSP-RS clinical diagnosis compared with both PD and HC, but low sensitivity and specificity profile in differentiating PSP-P from PD as well as from HC. The same measures show acceptable sensitivity and specificity profile in supporting clinical diagnosis of vPSP versus HC but not versus PD. Similar findings were detected for the newer MRPI and P/M versions.ConclusionsFurther studies are warranted to identify neuroimaging biomarkers supporting the clinical phenotypic categorisation of patients with PSP. MRPI and P/M have diagnostic value in supporting the clinical diagnosis of PSP-RS.Classification of evidenceThis study provides class III evidence that available MRI midbrain-based assessments do not have diagnostic value in differentiating the Movement Disorder Society PSP subtypes.

Abstract:
Objectives: This systematic review and meta-analysis aimed to compare chest tube drainage and conservative management as the initial treatment of primary spontaneous pneumothorax (PSP). Methods: Studies including PSP patients who received tube drainage or conservative management as the initial treatment were searched in OVID-MEDLINE and Embase through 14 February 2020. The primary outcome was the relative risk (RR) of PSP recurrence, and secondary outcomes were RRs of PSP resolution and adverse events during treatment. A random-effect model using the Mantel–Haenszel method was used to pool RRs. Subgroup and meta-regression analyses were performed to investigate significant predictors of PSP recurrence. Results: In total, 11,922 PSP cases from eight studies were analysed, of which 6344 were treated with tube drainage and 5578 were treated with conservative management. The pooled RR of PSP recurrence for conservative management against tube drainage was 0.98 (95% confidence interval [CI], 0.75–1.28; p = 0.894). Subgroup and meta-regression analyses revealed that study design (p = 0.816), allocation of the PSP amount in each management group (p = 0.191), and assessment time for recurrence had no significant impact on PSP recurrence (p = 0.816). There was no publication bias (p = 0.475). The risk of adverse events of conservative management was significantly lower than that of tube drainage (pooled RR, 0.22; 95% CI, 0.08–1.15; p = 0.003). However, no difference was found between the two groups in terms of PSP resolution (pooled RR, 1.01; 95% CI, 0.9–1.15; p = 0.814). Conclusions: As the initial treatment for PSP, conservative management is comparable to chest tube drainage in terms of PSP recurrence and resolution after treatment, with fewer adverse events during treatment.

Abstract Purpose The clinical presentation of idiopathic normal pressure hydrocephalus (iNPH) may overlap with progressive supranuclear palsy (PSP). The Magnetic Resonance Parkinsonism Index (MRPI), MRPI 2.0, and the interpeduncular angle (IPA) have been investigated to differentiate PSP from healthy controls (HC) and other parkinsonisms. We aimed to assess equivalences and differences in MRPI, MRPI 2.0, and IPA in iNPH, PSP, and HC groups. Methods We retrospectively recruited 99 subjects (30 iNPH, 32 PSP, 37 HC) from two institutions. MRI exams, acquired on either 1.5 T or 3 T scanners, included 3D T1-weighted images to measure MRPI, MRPI 2.0, and IPA. Inter- and intra-rater reliability was investigated with the intra-class correlation coefficient (ICC), and the two one-sided t tests (TOST) procedure was used to assess these markers in iNPH, PSP, and HC. Results For all the three measures, intra-rater and inter-rater ICC were excellent (range = 0.91–0.93). In the comparison of iNPH and PSP with HC, differences for MRPI and MRPI 2.0 (p < 0.01 in all cases) and no equivalence (p = 1.00 in all cases) were found at TOST. iNPH and PSP MRPI showed no difference (p = 0.06) and no equivalence (p = 0.08). MRPI 2.0 was not equivalent (p = 0.06) and not different (p = 0.09) in the same two populations. PSP and HC IPA proved equivalent (p < 0.01) while iNPH IPA was different (p < 0.01) and not equivalent (p = 0.96 and 0.82) from both PSP and HC. Conclusion MRPI and MRPI 2.0 significantly overlap in iNPH and PSP, with risk of misdiagnosis, and for this reason may not be helpful in the differential diagnosis.

Abstract:
ObjectiveTo evaluate the pattern and severity of autonomic dysfunction in autopsy-confirmed progressive supranuclear palsy (PSP) compared to α-synuclein pathology.MethodsAutopsy-confirmed cases of 14 patients with PSP, 18 with multiple system atrophy (MSA), and 24 with Lewy body disease (LBD) with antemortem autonomic testing were reviewed retrospectively. All patients underwent comprehensive clinical evaluations by a movement disorder specialist, formal autonomic testing, and postmortem examinations at Mayo Clinic.ResultsThe absence of orthostatic hypotension (OH) was the strongest autonomic parameter that distinguished PSP from α-synucleinopathies (0% vs 69%, p < 0.0001). Tests of adrenergic failure, which distinguish neurogenic OH, also differentiated PSP from other groups. These included the pressure recovery time (p = 0.0008), adrenergic impairment score (p = 0.001), and magnitude of change of systolic (p = 0.0002) and diastolic (p = 0.0001) blood pressures (BPs) during upright tilt. In addition, REM sleep behavior disorder was seen less frequently (p = 0.006) in PSP (33%) compared to MSA (87%) and LBD (90%). Antemortem clinical diagnostic accuracy for these phenotypically variable disorders was 57% for PSP and 83% for α-synucleinopathies.ConclusionOur results suggest that the cardiovascular adrenergic system, which sustains BP during standing, is relatively unaffected, if not spared, in PSP. These findings increase our understanding of the clinical signature of PSP and have the potential to improve diagnostic accuracy in atypical parkinsonisms by distinguishing PSP from the α-synucleinopathies.

Abstract:
Objectives. To explore the clinical correlates of nonmotor symptoms (NMS) in progressive supranuclear palsy (PSP) and their differences from healthy controls and patients with Parkinson’s disease (PD).Methods. Twenty-seven PSP patients, 27 age- and gender-matched healthy controls (HC), and 27 age- and gender-matched PD patients were included for this case-control study. NMS were assessed using the Nonmotor Symptoms Scale (NMSS, including 9 domains).Results. All PSP patients reported NMS. The frequency and severity of “sleep/fatigue,” “mood/apathy,” “attention/memory,” “gastrointestinal,” “sexual dysfunction,” and “miscellaneous” domains in PSP group were significantly higher than those in HC group (P<0.05). The frequency of “mood/apathy,” “attention/memory,” and “sexual dysfunction” domains and the severity of “attention/memory” and “gastrointestinal” domains in PSP group were significantly higher than those in PD group (P<0.05). The “attention/memory” domain in PSP had a significant but weak-to-moderate correlation with age (R=0.387,P=0.046) and onset age (R=0.406,P=0.036).Conclusions. NMS are common in PSP patients. Patients with PSP seem to be subjected to more frequent and severe specific NMS compared to healthy aging subjects and PD patients. Older PSP patients and late-onset patients are likely to be subjected to cognitive decline.

Abstract:
Pancreatic stone protein/regenerating protein Iα(PSP/REG Iα) is a secretory protein produced in the pancreas, but its expression has also been observed in the kidney. It may be associated with kidney dysfunction. This study investigates the possible association between PSP/REG Iαand kidney function in pregnant women. Serum PSP/REG Iαlevels were measured by a specific ELISA enzyme-linked immunosorbent assay. Maternal information and clinical and biochemical parameters were collected. Estimated glomerular filtration rate (eGFR) was calculated for all individuals to evaluate their renal function. Spearman’s correlation and multiple linear regression analyses were performed to assess the associations between PSP/REG Iαand eGFR, serum creatinine (Cr), blood urea nitrogen (BUN), and uric acid (UA). A total of 595 pregnant women were enrolled in the study. Participants with mildly reduced eGFR had higher PSP/REG Iαlevels [50.49 (35.02, 58.64)] than in the general population [26.84 (21.02, 33.07)] (p < 0.001). Included participants were stratified into PSP/REG Iαquartiles; significant differences were observed in the levels of eGFR, serum Cr, BUN, and UA. PSP/REG Iαwas negatively correlated with eGFR (r = −0.402, p < 0.001) and positively associated with serum Cr (r = 0.468, p < 0.001), BUN (r = 0.166, p < 0.001), and UA (r = 0.207, p < 0.001). The linear regression analysis indicated that PSP/REG Iαwas associated with UA, BUN, and eGFR. High PSP/REG Iαconcentrations were closely associated with renal dysfunction in pregnant women. Our study provides clinical evidence that serum PSP/REG Iαlevels could be a novel biomarker for assessment of renal function in pregnant women.

Abstract:
Abstract We developed a double-determinant immunoradiometric assay for measuring serum prostate secretory protein (PSP), using monoclonal antibodies (MAb) against two different epitopes: MAb PSP-19 was the capture antibody and MAb PSP-6 was the tracer antibody. Assay sensitivity was 0.1 microgram/L. Analytical recovery of PSP was 93.5-104.6%, whereas the intra- and interassay mean CVs were 4.2% and 6.9%, respectively. In 92 normal men, ages greater than 50 years, the mean PSP concentration was 5.7 micrograms/L, with 10 (10.9%) men having concentrations greater than 10 micrograms/L. In contrast, 20 of 49 (40.8%) patients with benign prostate hyperplasia (BPH; mean PSP concentration 9.4 micrograms/L) and 46 of 100 (46%) patients with prostate cancer (mean PSP concentration 22.2 micrograms/L) had PSP concentrations greater than 10 micrograms/L. Mean serum PSP concentrations of the BPH (P less than 0.05) and prostate cancer (P less than 0.01) groups were significantly different from those of age-matched normal men. In a small group of patients, serial PSP concentrations correlated with the clinical course during therapy. Thus, PSP may be a useful marker for evaluating patients with prostate cancer.

Abstract:
Introduction. Hypertension (HT) is a common serious condition associated with cardiovascular morbidity and mortality. The pathogenesis of HT is multifactorial and has been widely investigated. Besides the vascular, hormonal, and neurological factors, inflammation plays a crucial role in HT. Many inflammatory markers such as C-reactive protein, cytokines, and adhesion molecules have been studied in HT, which supported the role of inflammation in the pathogenesis of HT. Presepsin (PSP) is a novel biomarker of inflammation. Therefore, the potential relationship between PSP and HT was investigated in this study. Methods. Forty-eight patients with controlled HT and 48 controls without HT were included in our study. Besides routine clinical and laboratory data, PSP levels were measured in peripheral venous blood samples from all the participants. Results. PSP levels were significantly lower in patients with HT than in controls (144.98±75.98 versus 176.67±48.12 pg/mL, p=0.011). PSP levels were positively correlated with hsCRP among both the patient and the control groups (p=0.015 and p=0.009, resp.). However, PSP levels were not correlated with WBC among both groups (p=0.09 and p=0.67, resp.). Conclusions. PSP levels are not elevated in patients with well-controlled HT compared to controls. This result may be associated with anti-inflammatory effects of antihypertensive medicines.

Abstract:
Die Progressive Supranukleäre Blickparese (PSP) ist eine sporadisch auftretende neurodegenerative Erkrankung im Rahmen der atypischen Parkinson-Syndrome (APS), die im frühen Verlauf häufig mit dem Idiopathischen Parkinson-Syndrom (IPS) verwechselt wird. Dabei ist die Dysarthrie als eine erworbene, zentral bedingte sprechmotorische Störung ein häufiges und früh auftretendes Symptom bei PSP. Bislang spricht man von einer eher unspezifischen „gemischten“ Dysarthrie aus hypokinetischen, spastischen und auch ataktischen Komponenten. Im Rahmen einer explorativen Querschnittsstudie am „Fachkrankenhaus für Bewegungsstörungen und Parkinson“ Beelitz-Heilstätten in Kooperation mit der „Entwicklungsgruppe Klinische Neuropsychologie“ München (EKN) sowie der „Interdisziplinären Ambulanz für Bewegungsstörungen“ am Klinikum München-Großhadern wurden 50 Patienten dahingehend untersucht, ob sich für die Progressive Supranukleäre Blickparese (PSP) eine spezielle, frühzeitig zu diagnostizierende und differentialdiagnostisch relevante Dysarthrie beschreiben ließe. In diesem Zusammenhang soll geklärt werden, ob es sich um phänotypische Ausprägungen im Rahmen eines Störungsspektrums handelt oder ob sich differenzierbare Subtypen der Krankheit, insbesondere ein „klassischer“ PSP-Typ (PSP-RS) und ein „atypischer“ PSP-Typ (PSP-P), auch im Bereich der Dysarthrie zeigen. Im Rahmen der Untersuchungen wurde der Schweregrad der Erkrankung mittels der „PSP-sensitiven Ratingskala (PSPRS)“ gemessen. Die Dysarthriediagnostik erfolgte anhand der „Bogenhausener Dysarthrieskalen (BoDyS)“ zur Beschreibung der Art und Ausprägung der Dysarthrie bei PSP. Die Verständlichkeit wurde mithilfe des „Münchner Verständlichkeits-Profils (MVP)" sowie eines weiteren Transkriptionsverfahrens ermittelt, wobei Ausschnitte aus den Tests zum Lesen und Nachsprechen der BoDyS zugrunde lagen. Weiterhin erfolgte eine Einschätzung der Natürlichkeit des Sprechens. Die Ergebnisse hinsichtlich des Einflusses von Natürlichkeit und Verständlichkeit des Sprechens auf den Schweregrad der Dysarthrie zeigten, dass dieser modalitätenübergreifend mit beiden Schweregradaspekten korreliert, wenngleich es offenbar die Natürlichkeit des Sprechens ist, die bei PSP bereits frühzeitig beeinträchtigt ist und somit als das entscheidende differentialdiagnostische Kriterium zur Differenzierung zwischen beiden PSP-Subtypen zu beurteilen ist, möglicherweise auch gegenüber anderen Parkinson-Syndromen. Anhand statistisch valider Ergebnisse konnten spezifische Störungsmerkmale der Dysarthrie extrahiert werden, die eine signifikante Trennung von PSP-RS und PSP-P ermöglichen: eine leise und behaucht-heisere Stimme sowie ein verlangsamtes Sprechtempo und Hypernasalität. Damit können für die hier fokussierten Subtypen der PSP zwei unterschiedliche Dysarthrietypen postuliert werden. Danach wird dem Subtyp PSP-RS eine spastisch betonte Dysarthrie mit ausgeprägter Verlangsamung des Sprechtempos zugeordnet, dem Subtyp PSP-P hingegen eine hypokinetische Dysarthrie mit behaucht-heiserer Hypophonie. Desweiteren konnte ein „Dysarthrie-Schwellenwert“ als Zusatzkriterium für eine zeitliche Differenzierung beider PSP-Subtypen ermittelt werden. Anhand der Daten zeigte sich die Dysarthrie bei dem Subtyp PSP-RS gleich zu Beginn der Erkrankung, jedoch spätestens 24 Monate danach. Hingegen konnte die Dysarthrie beim Subtyp PSP-P frühestens 24 Monate nach Erkrankungsbeginn festgestellt werden. Die Daten dieser Studie verdeutlichen, dass der Frage nach einer subtypenspezifischen Ausprägung der Dysarthrie bei PSP eine Längsschnittsstudie folgen sollte, um die ermittelten Ergebnisse zu konsolidieren.<br>Progressive Supranuclear Palsy (PSP) is an atypical Parkinsonian syndrome characterized by gait ataxia, slowing or inability to generate vertical saccadic eye movements, axial rigidity, cognitive disorders and a progressive dysarthria. The dysarthria may include abnormalities in strength, speed, range, tone or accuracy of speech movements. As the disease progresses, important functional components of speech including respiration, phonation, resonance, articulation and prosody are affected. The question is what kind of dysarthria do we find in PSP? Until now it remains unclear, if the dysarthric characteristics of PSP vary in way as described by Williams et al. (2005) who found clinically distinct symptom patterns of a Parkinsonian form of PSP (PSP-P) distinct from a classical form (Richardson Syndrome). The aim of the cross-sectional multi center study was to investigate the specific dysarthric symptoms in patients with PSP. Until now it remains unclear, whether there are two different points on a continuous spectrum of speech disturbances or if there exist distinct „profiles“ of dysarthria according to the proposed Richardson Syndrome (PSP-RS) with early onset of postural instability and falls, vertical gaze palsy and cognitive dysfunctions and the PSP with Parkinsonism (PSP-P) with asymmetric onset, tremor, early bradykinesia, non-axial dystonia and response to levodopa medications in the beginning. „Bogenhausener Dysarthrieskalen“ (BoDys) was used as base-line dysarthria scale: pitch pattern, loudness range, voice quality, respiration and resonance capacities, prosody and articulation were rated. Furthermore, the intelligibility is a most important index of functional impairment in dysarthria. Therefore, the „Munich Intelligibility Profile (MVP)“, a computer-based method for the assessment of the intelligibility of dysarthric patients, was used to describe the intelligibility of the patients. The PSP-P-group, at the beginning frequently confused with patients with PD, showed rigide-hypokinetic dysarthric features with hypophonia as cardinal symptom. In contrast the patients with the “classical” PSP-RS-Type show severe speech impairments in terms of a very effortful speak with a progressive loss of intelligibility. They show spastic components of dysarthria, like a very strained-strangled voice with breaks and voice stoppages, harshness and reduced pitch and loudness variability. Their loudness often is inadequate in terms of the so called “lions voice”. Further they show a hypernasality, the articulation is imprecise, the vowels are distorted. Concerning the prosody there is a very slow and strained rate of speech with equal or excess stress. The results show that the patients with PSP-RS generally suffer from severe and more progressive speech impairments beginning early after disease onset, whereas the PSP-P-group shows rather moderate symptoms. The dysarthria in PSP is subtype-specific. The hypothesis of different dysarthric profiles for the proposed clinical subtypes "Richardson Syndrome" (PSP-RS) and "PSP with parkinsonism" (PSP-P) was confirmed and based on a discriminant analysis that identified distinctive dysarthric features for both subgroups.

Abstract:
La caracterisation de l'anisotropie sismique offre la possibilite de comprendre le role joue par les fractures et les fluides dans les processus tectoniques, de controler les caracteristiques des reservoirs geothermiques ou d'hydrocarbures, ou de detailler la structure de la croute terrestre. La presence d'anisotropie peut etre mise en evidence par l'etude des variations angulaires de la vitesse des ondes p, ou par l'analyse de la birefringence des ondes s. Une technique d'inversion des temps de trajet est developpee afin d'obtenir l'information vehiculee par les ondes p. La propagation de ces ondes en milieu transverse isotrope est calculee par la theorie des rais associee a des methodes perturbatives. Le probleme inverse est ensuite resolu par decomposition en valeurs singulieres. Les tests de sensibilite des temps aux parametres inverses, ont montre la necessite d'introduire de l'information a priori dans l'inversion. De meme, des exemples synthetiques ont souligne l'importance de disposer d'une bonne couverture angulaire et azimutale de la structure etudiee. L'application de cette methode tomographique a des donnees de puits du bassin parisien, a permis de detecter la presence d'anisotropie dans le cretace (argiles et sables), ainsi que dans les niveaux reservoirs. L'origine de l'anisotropie est attribuee a l'existence de micro-fractures verticales orientees dans la direction du champ de contrainte regional. La birefringence des ondes s est etudiee sur le site de soultz-sous-forets, avant et pendant des injections d'eau en puits profond, dans le but d'identifier les zones de flux dans les systemes de fractures naturelles. Avant injection, le socle granitique apparait homogene et isotrope, et la presence de failles majeures a ete detectee ; de l'anisotropie est par ailleurs observee dans les sediments superficiels. Au cours de l'injection, les proprietes isotropes du massif ne sont pas affectees. Cependant, des modifications des temps de trajet semblent indiquer l'accentuation d'une structure heterogene, liee a la percolation du fluide injecte

Neste trabalho obteve-se, com o experimento STAR, medidas de produção de J/&psi; e &upsih; em rapidez central (&eta;=0), em colisões p+p com &radic;s = 200 GeV no RHIC. A medida de &upsih; foi a primeira medida de bottomonium em rapidez central no RHIC. Essas medidas servem como linha de base para a investigação experimental sistemática da supressão de heavy-quarkonium, tida como uma evidência observacional do Plasma de Quarks e Glúons (QGP). Para a realização dessas medidas foi desenvolvido um sistema específico de gatilho de eventos para heavy-quarkonium, envolvendo, em sua configuração, os subsistemas do calorímetro eletromagnético (BEMC) e do cilindro de gatilho central (CTB, apenas para J/&psi;).

These measurements can be used as the baseline of the systematic experimental investigation on heavy-quarkonium suppression, believed to be one important observational evidence of the existence of the Quark-Gluon Plasma (QGP). In order to acquire the data for these analyses, it was necessary to develop a new heavy-quarkonium trigger system, based on the Barrel Electromagnetic Calorimeter (BEMC) and the Central Trigger Barrel (CTB, J/&psi; only) detectors. The inclusive J/&psi; cross section at mid-rapidity is BRee&times;&sigma;J/&psi;incl = 122(23)estat(27)sist. (nb) and for the &upsih;, BRee&times;d&sigma;&upsih;/dy|y=0 = 114 (29)estat(24)sist.(pb). In the case of the J/&psi; measurement, we acquired enough statistics to obtain a transverse momentum spectrum and the mean squared transverse momentum is &lsaquo; pT2&rsaquo;=3,43(68) (GeV/c)2. These results were compared to theoretical predictions of 3 different models, the Color Singlet Model (CSM), the Non-Relativistic QCD (NRQCD) and the Color Evaporation Model (CEM), as well as to other experimental data. Except for the CSM, all the predictions agree reasonably well with the data.

Abstract:
La teoria dell’interazione forte, la Cromodinamica Quantistica, non è tuttora risolvibile completamente. Le sue proprietà emergenti in sistemi interagenti sono dunque il soggetto della maggior parte degli studi nella fisica degli ioni pesanti. Le collisioni protone-protone possono fornire un punto di vista alternativo su questo argomento, con differenti limitazioni ma anche dfferenti possibilità. Questa tesi si propone di investigare su possibili indizi di fenomeni collettivi, come la formazione di plasma di quark e gluoni, in collisioni protone-protone. Per questo scopo, è stato effettuato uno studio sulla dipendenza dalla molteplicità delle produzioni di J/ψ and ψ(2S) e dei loro rapporti, all’energia di √s = 7 TeV nell’ambito dell’esperimento CMS al Large Hadron Collider. I risultati sono stati poi discussi e messi in relazione con altri recenti dati sperimentali. La tesi è organizzata nel seguente modo: • nel Capitolo 1 vengono presentate un’introduzione alla teoria della Cromodinamica Quantistica e una panoramica sulla fenomenologia del plasma di quark e gluoni; • nel Capitolo 2 vengono introdotte le principali caratteristiche dell’esperimento CMS al Large Hadron Collider; • nel Capitolo 3 viene descritta la valutazione dei valori di produzione di J/ψ and ψ(2S), e successivamente la separazione delle loro frazioni dirette e indirette; • nel Capitolo 4 viene discusso il calcolo della molteplicità di tracce cariche, ovvero il numero di particelle cariche primarie prodotte nella collisione, che deve essere associato ad ogni coppia di muoni; • nel Capitolo 5 si studia l’andamento in funzione della molteplicità carica dei valori di produzione di J/ψ and ψ(2S) e dei loro rapporti. Inoltre si studia l’andamento, sempre in funzione della moltpelicità carica, dell’impulso trasverso medio di J/ψ and ψ(2S); • nel Capitolo 6 i risultati sono discussi e confrontati con altri recenti studi sperimentali.

Abstract:
In questo lavoro di tesi è stato studiato lo spettro di massa invariante del sistema J/psi pi+ pi-, m(J/psi pi+ pi-), in collisioni protone-protone a LHC, con energia nel centro di massa sqrt(s)) pari a 8 TeV, alla ricerca di nuovi stati adronici. Lo studio è stato effettuato su un campione di dati raccolti da CMS in tutto il 2012, corrispondente ad una luminosità integrata di 18.6 fb-1. Lo spettro di massa invariante m(J/psi pi+ pi-), è stato ricostruito selezionando gli eventi J/psi->mu+ mu- associati a due tracce cariche di segno opposto, assunte essere pioni, provenienti da uno stesso vertice di interazione. Nonostante l'alta statistica a disposizione e l'ampia regione di massa invariante tra 3.6 e 6.0 GeV/c^2 osservata, sono state individuate solo risonanze già note: la risonanza psi(2S) del charmonio, lo stato X(3872) ed una struttura più complessa nella regione attorno a 5 GeV/c^2, che è caratteristica della massa dei mesoni contenenti il quark beauty (mesoni B). Al fine di identificare la natura di tale struttura, è stato necessario ottenere un campione di eventi arricchito in adroni B. È stata effettuata una selezione basata sull'elevata lunghezza di decadimento, che riflette la caratteristica degli adroni B di avere una vita media relativamente lunga (ordine dei picosecondi) rispetto ad altri adroni. Dal campione così ripulito, è stato possibile distinguere tre sottostrutture nello spettro di massa invariante in esame: una a 5.36 GeV/c^2, identificata come i decadimenti B^0_s-> J/psi pi+ pi-, un'altra a 5.28 GeV/c^2 come i candidati B^0-> J/psi pi+ pi- e un'ultima allargata tra 5.1 e 5.2 GeV/c^2 data da effetti di riflessione degli scambi tra pioni e kaoni. Quest'ultima struttura è stata identificata come totalmente costituita di una combinazione di eventi B^0-> J/psi K+ pi- e B^0_s-> J/psi K+ K-.

Abstract:
L'experience na38 etudie la production de dimuons dans des collisions induites par des ions lourds a 200 gev par nucleon. Quand la densite d'energie augmente, une suppression de la production du meson j/psi par rapport aux paires de muons dans le continuum a ete observee. Cet effet est attendu en cas de formation d'un plasma de quarks et de gluons, etat de la matiere nucleaire predit par la chromodynamique quantique. La principale difficulte de cette analyse reside dans l'evaluation de l'important bruit de fond genere par les desintegrations de pions et de kaons. Le present travail reprend l'analyse de l'ensemble des donnees de l'experience, sur la base d'une methode statistique d'estimation du bruit de fond. Cette methode, qui s'appuie sur l'information tiree des muons simples deduits des paires de muons mesurees dans l'appareillage, permet une amelioration sensible de la precision sur le signal. Cette analyse montre que la suppression relative du j/spi par rapport au continuum est plus importante dans les reactions noyau-noyau que dans les reactions proton-noyau. De plus, elle montre que la production de dimuons dans le continuum depend de l'isospin du projectile, ce qui rend delicate la comparaison aux collisions induites par des protons. Efin l'etude de la production du j/psi en fonction de la densite d'energie ne permet pas de favoriser une interpretation de la suppression en termes de plasma plutot qu'en termes d'absorption dans le gaz de mesons, bien que la valeur absolue de l'effet ne soit pas totalement comprise

Abstract In this paper the direct and the inverse position analysis of a 3-dof fully-parallel mechanism, known as 3-PSP mechanism, is addressed and solved in analytical form. The 3-PSP mechanism consists of two rigid bodies, one movable (platform) and the other fixed (base), connected to each other by means of three equal serial kinematic chains (legs) of type PSP, P and S standing for prismatic and spherical pair respectively. Both the direct and the inverse position analysis of this mechanism lead to non-linear equations that are difficult to solve. In particular, the inverse position analysis comprises different sub-problems which need specific solution techniques. Finally a numerical example is reported.

Abstract:
An innovative pressure-measurement technique that employs the tools of molecular spectroscopy has been widely investigated by the aerospace community. Measurements are made via oxygen-sensitive molecules attached to the surface of interest as a coating, or paint. The pressure-sensitive-paint (PSP) technique is now commonly used in stationary wind-tunnel tests; this paper presents the use of this technique in advanced turbomachinery applications. New pressure- and temperature-sensitive paints (P/TSPs) have been developed for application to a state-of-the-art transonic compressor where pressures up to 1.4 atm and surface temperatures to 90°C are expected for the suction surface of the first-stage rotor. PSP and TSP data images have been acquired from the suction surface of the first-stage rotor at 85% of the corrected design speed for the compressor near-stall condition. A comparison to over-the-rotor pressure transducer measurements will be presented.

Abstract:
This study investigates the combined effects of blowing ratio and density ratio on flat plate film cooling effectiveness from two-row of compound angled cylindrical holes. Two arrangements of two-row compound angled cylindrical holes are tested: the first row and second row are oriented in staggered but same compound angled direction (β = +45° for the first row, +45° for the second row); the first row and second row are oriented in inline but opposite direction (β = +45° for the first row, −45° for the second row). Each cooling hole is 4 mm in diameter with an inclined angle 30°. The streamwise distance between the two rows is fixed at 4d and the spanwise pitch between the two holes (p) is 4d, 6d, and 8d, respectively. The experiments are performed at four blowing ratios (M = 0.5, 1.0, 1.5, 2.0) and three density ratios (DR = 1.0, 1.5, 2.0). The free stream turbulence intensity is kept at 6%. Detailed film cooling effectiveness distributions are obtained using the steady state pressure-sensitive paint (PSP) technique. The detailed film cooling effectiveness contours are presented and the spanwise averaged film effectiveness results are compared over the range of flow parameters. Film cooling effectiveness correlations are developed for both inline and staggered compound angled cylindrical holes. The results provide baseline information for the flat plate film cooling analysis with two-row of compound angled cylindrical holes.

Abstract:
The interaction of flow and film-cooling effectiveness between jets of double-jet film-cooling (DJFC) holes on a flat plate is studied experimentally. The time-averaged secondary flow field in several axial positions (X/d = −2.0, 1.0, and 5.0) is obtained through a seven-hole probe. The downstream film-cooling effectiveness on the flat plate is achieved by Pressure Sensitive Paint (PSP). The inclination angle (θ) of all holes is 35°, and the compound angle (β) is ±45°. Effects of spanwise distance (p = 0, 0.5d, 1.0d, 1.5d, 2.0d) between the two interacting jets of DJFC holes are studied while streamwise distance (s) is kept as 3d. The blowing ratio (M) varies as 0.5, 1.0, 1.5, and 2.0. The density ratio (DR) is maintained at 1.0. Results show that the interaction between two jets of DJFC holes has different effects for different spanwise distance. For a small spanwise distance (p/d = 0), the interaction between jets presents a pressing effect. The downstream jet is pressed down and kept attached to the surface by the upstream one. The effectiveness is not sensitive to blowing ratios. For mid spanwise distances (p/d = 0.5 and 1.0), the anti-kidney vortex pair dominates the interaction, and pushes both of the jets down, thus leads to better coolant coverage and higher effectiveness. As spanwise distance becomes larger (p/d≥1.5), the pressing effect almost disappears, and the anti-kidney vortex pair effect is weaker. The jets separate from each other and the coolant coverage decreases. At higher blowing ratio, the interaction between the two jets of DJFC holes moves more downstream.

Abstract:
Several double-jet film-cooling (DJFC) hole geometries on a flat plate are investigated in this paper. Pressure sensitive paint (PSP) is used to measure the film-cooling effectiveness on the flat plate. The streamwise distance between the DJFC holes varies as s/d = 3.0, 4.0, 5.0, and 6.0, while three different spanwise distance conditions are considered (p/d = 0, 0.5, and 1.0). The diameter (d) of the DJFC holes is 7 mm, and the pitch (P) between each set of the DJFC holes is 8d. The holes have an inclination angle (θ) of 35°, and a compound angle (β) of ± 45°. The density ratio (DR) varies as 1.0, 1.5, and 2.5, and the blowing ratio (M) is 0.5, 1.0, 1.5, and 2.0. Both effects of the streamwise distance between DJFC holes, and the density ratio on film-cooling effectiveness are focused. Results show, though the effect of the streamwise distance is not monotonic all the time, a general trend exists when comparing with the baseline case of s/d = 3.0. For p/d = 0, increasing the streamwise distance leads to wider lateral coverage and higher laterally averaged effectiveness; however, for p/d = 0.5 and 1.0, an increased s/d may weaken the interaction between the two jets, thus the film coverage and effectiveness decrease. A higher density ratio reduces the jet momentum, therefore better attachment and higher effectiveness are obtained. Effects of the streamwise distance and the density ratio on double-jet film-cooling are more distinct when the blowing ratio rises. However, in most cases, both of them show minor influence on the range of lateral coverage, as it is mainly dominated by the spanwise distance. For each operation condition (DR and M), an optimal DJFC configuration (among the geometries in this study) is identified by comparing the area averaged effectiveness.

Abstract:
An experimental investigation of effusion film cooling has been completed for cylindrical, simple angle holes (θ = 20°), using a steady state, pressure sensitive paint (PSP) technique. The surface effectiveness measurements were obtained in a low speed wind tunnel where the average blowing ratio (M) was varied from 0.5 to 6. For all cases, the coolant–to–mainstream density ratio was fixed at DR = 1.0. The test surface was manufactured using direct metal laser sintering (DMLS), and was made to replicate full coverage film cooling typically seen for combustor cooling applications. The plate contained 10 staggered rows of film cooling holes, with P/D = 9.8 and S/D = 8.5. At blowing ratios greater than M = 1.0, the downstream film cooling effectiveness is greatly improved by the protection provided from the high momentum jets in the upstream rows. Within the latter-half of the matrix, the effectiveness measured on the surface gradually increased with each passing row. The combination of the holes made a substantial impact downstream, and the effect continued to grow all the way through the end of the plate. With the accumulation of the coolant above the surface, the coolant liftoff was mitigated and enhanced protection was observed on the surface. The DMLS manufacturing technique created surface and hole interior roughness. The hole interior roughness reduced the lateral average film cooling effectiveness by at least 50% when compared to previous investigations.

Full text
Abstract:
Film cooling is a cooling method used to protect the hot components of a gas turbine from high temperature conditions. For this purpose, high and uniform film cooling effectiveness is required to protect the vanes/blades from excessive thermal stress. Backward injection is proposed as one of the methods for the improvement of film cooling effectiveness. In this study, experiments were performed to investigate the effect of backward injection on film cooling effectiveness, using pressure sensitive paint (PSP) method. Four experimental configurations were composed of forward and backward injection cylindrical holes. The cylindrical holes were aligned in two staggered rows with pitch (p) of 6d and row spacing (s) of 3d. The injection angles (α) of the cylindrical holes were 35° and 145° for forward and backward injection, respectively. The blowing ratios (M) ranged from 0.5 to 2.0 and the density ratio (DR) was about 1. The results indicate that backward injection enhanced not only film cooling effectiveness but also the lateral cooling uniformity. At a high blowing ratio, all configurations demonstrated higher film cooling effectiveness with backward injection than with only forward injection; thus, the dispersion of the backward injection jets enhanced the lateral coverage over wide areas. Configuration, in particular, arranged with forward injection in the first row and backward injection in the second row, obtained the highest film cooling effectiveness among the four cases studied, due to the dispersion of the backward injection jets and the coolant supply from the forward injection jets at a high blowing ratio.

Abstract:
This paper presents a new configuration of discrete film hole, i.e., the slot-based diffusion hole. Retaining the similar diffusion features to a traditional diffusion hole, the slot-based diffusion hole transforms the cross section of circle for the traditional diffusion hole to a flattened rectangle with respect to the equivalent cross-sectional area. Consequently, the exit width of the new hole is effectively enlarged. To verify the film cooling effectiveness, a low speed flat plate experimental facility incorporated with Pressure Sensitive Paint (PSP) measurement technique was employed to obtain the adiabatic film cooling effectiveness. The experiments were performed with hole pitch to diameter ratio p/D=6 and density ratio DR=1.38. The blowing ratio was varied from M=0.5 to M=2.5. A fan-shaped hole and two slot-based diffusion holes were tested and compared. Three-dimensional numerical simulation was employed to analyze the flow field in detail. The experimental results showed that the area averaged effectiveness of two slot-based diffusion holes is significantly higher than that of the fan-shaped hole when the blowing ratio exceeds 1.0. The slot-based diffusion hole demonstrates the great advantage over the fan-shaped hole at hole exit and maintains this to far downstream. The numerical results showed that the ends shape of the flattened rectangular cross section has large influences on film distribution patterns and downstream vortex structures. The semi-circle and straight line ends shapes lead to a bi-peak and a single-peak effectiveness pattern, respectively. The optimal ends shape can regulate the vortex structures and improve the film cooling effectiveness further.

Abstract:
&lt;p&gt;In this study, the flexural behavior of pre-stressed concrete-I (PSC-I) girders was investigated to intuitively and more accurately evaluate the structural behavior and load-carrying capacity increase of PSC-I girder bridges more than 40 years old and reinforced by the external pre-stressing (PS) tendon reinforcement method. Many bridges in South Korea, which were constructed after the 1960s, exhibit a significantly low load-carrying capacity due to aging and the application of loads that are different from originally designed loads. To improve the load-carrying capacity and working load of these old bridges, reinforcement methods that use external PS tendons have been conventionally used. However, the evaluation of the load-carrying capacity of a bridge and the calculation of the number of external tendons for reinforcement are performed through the vehicle load test within the working load range of the bridge. Most of the studies conducted so far have been limited to the calculation of the loss of the members required for the reinforcement of the bridge or their structural behavior. In this study, a flexural failure verification experiment was performed on PSC-I girder bridges that were constructed based on the standard design of the 1960s to verify the reinforcement effect of PS tendons. The target of the experiment was the girders of PSC-I girder bridges designed more than 40 years ago based on the working loads of DB-18 and DB- 24.&lt;/p&gt;
