Dissemination, redissemination and fiber life

The technical background of dissemination of carbon fibers as well as the possibility of redissemination and fiber life are outlined. Plume spread and weather, measures of pollution and of damage potential, and parameters controlling dissemination patterns are among the topics discussed. It is shown that the redissemination rate off hard surfaces decreases with time and that fiber length decreases with time. Redissemination from vegetated land is shown to be insignificant

When Deciding Whether to Transfer Venue, Bankruptcy Courts will Consider Their Discretion to Retain a Case, as well as the Interests of Justice and Convenience of the Parties

(Excerpt) When a debtor decides to file a petition for bankruptcy, one decision to make is in what court, or what jurisdiction to file. However, the debtor’s choice of where to file is not always indisputable. Once a case is filed in a particular court, any “party in interest” may bring a motion seeking to change the venue of the case to an alternate court. Additionally, a court, on its own motion, may transfer a case to an alternate venue. The three statutory provisions that govern transfers of venue are Bankruptcy Rule 1014 (“Rule 1014”), 28 U.S.C. § 1408 (“Section 1408”), and 28 U.S.C. § 1412 (the substantive equivalent of Rule 1014). This article primarily discusses Rule 1014, however, it is important to note that Section 1408 provides the criteria for what constitutes proper venue. These considerations include the debtors’ and creditors’ domicile, residence, principal place of business, and principal assets. However, the statutory interpretation of Rule 1014(a)(2) is what will be focused on in this article. Rule 1014(a)(2) states in pertinent part, “[i]f a petition is filed in an improper district, the court, on timely motion of a party in interest or on its own motion . . . may dismiss the case or transfer it to any other district if the court determines that transfer is in the interest of justice or convenience of the parties.” The language of this provision poses two issues: (1) What discretion does a bankruptcy court have to retain a case filed in an improper venue; and (2) what constitutes in the interest of justice and convenience to the parties? The majority of courts have held that a bankruptcy court does not have discretion to retain jurisdiction over an improperly venued case upon a timely-filed objection. Furthermore, when determining what constitutes the interest of justice and convenience of the parties under Rule 1014, courts will consider several practical and equitable factors. This article explores how courts have interpreted Rule 1014 in a twofold approach. Part I discusses whether a court has the discretion to retain a case even if it was filed in the improper venue. Part II examines what constitutes “in the interest of justice and convenience of the parties” under Rule 1014

Schwingungseigenschaften der Ossikel und der Cochlea und deren Bedeutung für unser Gehör

Zusammenfassung: Untersuchungen der Bewegungen von Trommelfell und Steigbügel belegen, dass in den höheren Frequenzen komplexe, räumliche Vibrationsmuster auftreten, bei denen sich die einzelnen Elemente in sehr unterschiedlichen räumlichen Richtungen und in sehr unterschiedlichen Phasenlagen bewegen. Am Steigbügel sind eine kolbenförmige Bewegung sowie eine Rotation um die kurze und lange Steigbügelachse zu unterscheiden. Im Gegensatz zu den kolbenförmigen Schwingungen führen Rotationsbewegungen nicht zu einer Nettovolumenverschiebung der cochleären Flüssigkeit in einem gewissen Abstand von der Fußplatte. Deshalb wird aufgrund der gängigen Theorie des Hörens angenommen, dass solche Kippbewegungen keinen Einfluss auf das Gehör haben. In einer Reihe von Studien wurde jedoch qualitativ gezeigt, dass auch Kippbewegungen zu cochleärer Aktivität führen können. Weitere Forschung ist notwendig, um diesen Effekt zu quantifiziere

"Visuelle Elemente" in Qualitätszeitungen im Wandel

Ziel der Magisterarbeit war es zu untersuchen, ob sich der Einsatz von visuellen Elementen" (Fotografien, Infografiken, Cartoons und Illustrationen) in Qualitätszeitungen in den vergangenen Jahrzehnten verändert hat. Zu diesem Zweck wurden die drei deutschen Qualitätszeitungen Frankfurter Allgemeine Zeitung, Süddeutsche Zeitung und Die Welt untersucht. Insgesamt wurden 782 visuelle Elemente zwischen den Jahren 1950 und 2000 in einer zufallsgesteuerten Stichprobe gezogen. Diese wurden mit einer Inhaltsanalyse auf formale Kriterien, wie z.B. Art des visuellen Elements, Platzierung, Format, Größe, Funktion und Farbigkeit geprüft. Die Auswertung ergab, dass sich der Einsatz visueller Elemente vor allem in den letzten zwei Jahrzehnten verändert hat, allerdings für jede der drei Zeitungen in einem anderen Maße. So trifft die Wendung zum Bild, der 'pictorial turn', am stärksten auf Die Welt zu. Im Gegensatz dazu stellte die FAZ, die auch heute noch sehr zurückhaltend Abbildungen einsetzt, die Qualität vor die Quantität. Die SZ ist aufgrund der Ergebnisse zwischen diesen beiden Zeitungen einzuordnen, ihr Bildanteil hat zugenommen - allerdings langsam und kontinuierlich. Fazit: Visuelle Elemente sind ein zentrales Kriterium für die Modernität einer Zeitungsgestaltung. Ganz besonders ist dies bezeichnend für die zunehmende Zahl der Infografiken. Allerdings behalten Fotografien weiterhin ihre dominante Stellung

The Effect of a Values Clarification Strategy on the Smoking Behavior of Pregnant Women

The null hypothesis of this study stated that there would be no significant difference (α=.05) in the change in smoking behavior following a teaching intervention to discourage smoking in pregnant women between those who completed a values clarifying strategy prior to the intervention and those who did not. Forty subjects were randomly assigned 20 to an experimental group and 20 to a control group. Both groups completed a pretest questionnaire concerning demographic data and smoking behavior. Information regarding the adverse effects on the fetus and on the developing child of smoking was presented to each subject by the researcher. The members of the experimental group completed a values clarifying strategy prior to receiving this information. A posttest questionnaire concerning smoking behavior was completed four weeks later by 14 of the control group and by 15 of the experimental group, the control group reduced their smoking behavior, four remained unchanged, Seven of and three increased their smoking behavior. Eleven of the experimental group reported reduced smoking behavior and four remained unchanged. The Mann Whitney U and the Binomial Test for Equality of Proportions were the statistical tests used to analyze the smoking behavior data. The difference in reduction of smoking behavior between the groups was not found to be significant at the 5 percent level; however, a trend was found in favor of decreased smoking in the experimental group: p=.07 using the Mann Whitney U and p=.09 using the Binomial Test for Equality of Proportions. The null hypothesis was retained. A t-test was run on the comparison of changes between the experimental and control groups in decreased number of cigarettes and gave a significant difference (p=.05). Due to skewing of the distribution of the differences for the experimental group, the test was declared inappropriate. The difference between the groups on the number of pregnancy variable was significant (p=.05), yet the correlation between this variable and the variable change in the number of cigarettes was not significantly different from zero (r=.003)

[99mTc]Tc-PSMA-I&S-SPECT/CT: experience in prostate cancer imaging in an outpatient center.

Prostate-specific membrane antigen (PSMA) SPECT imaging in prostate cancer (PCa) could be a valuable alternative in regions where access to PSMA-PET imaging is restricted. [ <sup>99m</sup> Tc]Tc-PSMA-I&S is a new <sup>99m</sup> Tc-labeled PSMA-targeting SPECT agent, initially developed for radio-guided surgery. We report on the diagnostic use of [ <sup>99m</sup> Tc]Tc-PSMA-I&S-SPECT/CT in PCa. [ <sup>99m</sup> Tc]Tc-PSMA-I&S-SPECT/CT was performed and evaluated in 210 outpatients with PCa at a single center. Patients were imaged for biochemical recurrence (BCR, n = 152, mean PSA 8.7 ng/ml), for primary staging of high-risk PCa (n = 12, mean PSA 393 ng/ml), and restaging in advanced recurrent PCa (n = 46, mean PSA 101.3 ng/ml). Number and location of positive lesions were determined for the different subgroups. For BCR, detection rates were calculated, defined as the proportion of scans with at least one PSMA-positive lesion. PSMA positive lesions were detected in 65.2% of all 210 patients. Tumor tissue was mainly detected in lymph nodes (59%), in the bone (42%), and in the prostate (fossa) (28%). In the subgroup of patients referred for detection of BCR the detection rate increased from 20% at a PSA level < 1 ng/ml to 82.9% and 100% at PSA levels > 4 ng/ml and > 10 ng/ml, respectively. In the subgroup of high-risk patients referred for primary staging, 42% demonstrated metastatic disease. Restaging of advanced recurrent PCa revealed detectability of PSMA positive tumor lesions in 85% of the scans. [ <sup>99m</sup> Tc]Tc-PSMA-I&S-SPECT/CT was useful in PSMA-targeted imaging of PCa at various clinical stages. At low PSA levels (< 4 ng/ml), detection rates of [ <sup>99m</sup> Tc]Tc-PSMA-I&S-SPECT/CT in BCR are clearly inferior to data reported for PET-imaging and should thus only be considered for lesion detection if imaging with PET is unavailable. However, at higher PSA levels (> 4 ng/ml) [ <sup>99m</sup> Tc]Tc-PSMA-I&S-SPECT/CT provides high detection rates in BCR. [ <sup>99m</sup> Tc]Tc-PSMA-I&S-SPECT/CT can also be used for primary staging and for restaging of advanced recurrent PCa. However, further studies are needed to assess the clinical value in these indications

Comment construit-on des outils didactiques adaptés à un contexte d'enseignement de FLE ?

National audienceCette étude interroge la notion de contextualisation didactique en prenant comme terrain de recherche le projet « Parcours Intégré de Français Langue Étrangère (FLE) » visant à construire une mallette pédagogique adaptée à des bénévoles non-formés à l'enseignement du FLE qui souhaitent animer des cours de français auprès de migrants non-francophones. Mes objectifs sont de 1) décrire la démarche de contextualisation didactique du projet et 2) identifier les catégories du contexte considérées dans la démarche et dans les outils construits
