Wirksamkeit eines spezifisch für Zwangsstörungen entwickelten stationären Gruppentherapiekonzepts bei gleichzeitiger Verhaltenstherapie und pharmakologischer Behandlung

Purpose: The goal of this treatment trial was to investigate the efficacy of an inpatient group therapy program specifically designed for patients suffering from Obsessive Compulsive Disorder (OCD, ICD 10, F 42). Methods: In the experimental group (EG; n = 14) the specific group therapy was carried out in addition to individual cognitive-behavioral therapy, the control group (KG; n = 16) received non-specific group therapy in mixed patient-groups in addition to individual therapy. 7 patients (EG = 3, KG = 4) received also Selective Serotonin re-uptake inhibitors (SSRIs). Y-BOCS, BDI, and STAI-X1 were performed pre- and post-treatment. Furthermore therapists' ratings and self ratings were taken. Results: At post-treatment both groups showed significant improvement of the symptomatology. For the EG the Y-BOCS mean was reduced from 23.64 to 11.35, for the KG from 23.81 to 12.81. The group comparison showed no significant differences (alpha = 0.05) in clinical measurements, therapists' and self ratings. However, there were significantly more responders (improvement >50%, Y-BOCS) in the EG and treatment duration was shorter by 15 days. Conclusions: Clinical outcome in the EG was not superior. However, the specific group therapy for OCD contributes to an economic and effective treatment

In-plane anisotropy of electrical transport in Y0.85_{0.85}Tb0.15_{0.15}Ba2_2Cu3_3O7−x_{7-x} films

We fabricate high-quality c-axis oriented epitaxial YBa$_2$Cu$_3$O$_{7-x}$ films with 15% of yttrium atoms replaced by terbium (YTBCO) and study their electrical properties. The Tb substitution reduces the charge carrier density resulting in increased resistivity and decreased critical current density compared to the pure YBa$_2$Cu$_3$O$_{7-x}$ films. The electrical properties of the YTBCO films show an in-plane anisotropy in both the superconducting and normal state providing evidence for the twin-free film. Unexpectedly, the resistive transition of the bridges also demonstrates the in-plane anisotropy that can be explained within the framework of Tinkham's model of the resistive transition and the Berezinskii-Kosterlitz-Thouless (BKT) model depending on the sample parameters. We consider YTBCO films to be a promising platform for both the fundamental research on the BKT transition in the cuprate superconductors and for the fabrication of devices with high kinetic inductance

Das Naturschutzgebiet Aland-Elbe-Niederung – Ausweisung eines NSG zur Umsetzung der Ziele von NATURA 2000

Die EU verabschiedete am 21. Mai 1992 die Richtlinie zur Erhaltung der natürlichen Lebensräume sowie der wildlebenden Tiere und Pflanzen, die sogenannte Fauna-Flora-Habitat-Richtlinie (FFH-Richtlinie). Die Mitgliedsstaaten sind seitdem verpflichtet, ein europaweites Netz von besonderen Schutzgebieten zur Erhaltung der biologischen Vielfalt und zur Förderung einer nachhaltigen Entwicklung aufzubauen. In dieses Natura 2000 genannte Netz sind auch die auf der Grundlage der seit 1979 geltenden EU-Vogelschutzrichtlinie gemeldeten Europäischen Vogelschutzgebiete (EU SPA) integriert. Die reichhaltige Naturausstattung Sachsen-Anhalts ermöglichte die Auswahl von 265 FFH-Gebieten und 32 Vogelschutzgebieten (EU SPA). Die Gebiete wurden als „Gebiete von gemeinschaftlicher Bedeutung der kontinentalen und der atlantischen biogeographischen Region“ im Amtsblatt der EU vom 15.01.2008 veröffentlicht. Nach den Vorgaben der FFH- und Vogelschutzrichtlinie sind die Natura 2000-Gebiete nun als besondere Schutzgebiete national zu sichern. Darüber hinaus sind in den besonderen Schutzgebieten geeignete Maßnahmen zu treffen, um die Verschlechterung der natürlichen Lebensräume und der Habitate der Arten, für die die Gebiete ausgewiesen worden sind, zu vermeiden (vgl. Art. 6, Abs. 2 FFH Richtlinie). Alle erforderlichen Maßnahmen sind an den Ansprüchen der in den jeweiligen Gebieten vorkommenden Lebensraumtypen und Arten auszurichten. Mit dem vorliegenden Sonderheft wird beispielhaft der Verfahrensweg der Ausweisung des Naturschutzgebietes Aland-Elbe-Niederung zur Umsetzung von Natura 2000 im Land Sachsen-Anhalt dokumentiert. Neben der Darstellung der naturräumlichen Situation des Gebietes und seiner naturschutzfachlichen Bedeutung werden insbes. Inhalt und Ablauf des Verwaltungsverfahrens sowie die Lösung der vielfältigen Nutzungskonflikte dargestellt. Dem Heft liegt eine beidseitig bedruckte Schutzgebietskarte des Landes Sachsen-Anhalt im Maßstab 1:250.000 bei. Auf einer Seite sind Schutzgebiete nach internationalem Recht dargestellt. Die zweite Seite der Karte liefert eine aktuelle Zusammenstellung (Stand 31.12.2009) der nach Landesnaturschutzrecht geschützten Gebiete und Objekte. Ein Beiheft mit Namen, Bezeichnung und Größe aller Gebiete komplettiert die Ausgabe

Measurement of the Neutron Spin Structure Function g1ng_1^n with a Polarized ^3He Target

Results are reported from the HERMES experiment at HERA on a measurement of the neutron spin structure function $g_1^n(x,Q^2)$ in deep inelastic scattering using 27.5 GeV longitudinally polarized positrons incident on a polarized $^3$He internal gas target. The data cover the kinematic range $0.023<x<0.6$ and $1 (GeV/c)^2 < Q^2 <15 (GeV/c)^2$. The integral $\int_{0.023}^{0.6} g_1^n(x) dx$ evaluated at a fixed $Q^2$ of $2.5 (GeV/c)^2$ is $-0.034\pm 0.013(stat.)\pm 0.005(syst.)$. Assuming Regge behavior at low $x$, the first moment $\Gamma_1^n=\int_0^1 g_1^n(x) dx$ is $-0.037\pm 0.013(stat.)\pm 0.005(syst.)\pm 0.006(extrapol.)$.Comment: 4 pages TEX, text available at http://www.krl.caltech.edu/preprints/OAP.htm

Flavor Decomposition of the Polarized Quark Distributions in the Nucleon from Inclusive and Semi-inclusive Deep-inelastic Scattering

Spin asymmetries of semi-inclusive cross sections for the production of positively and negatively charged hadrons have been measured in deep-inelastic scattering of polarized positrons on polarized hydrogen and 3He targets, in the kinematic range 0.023<x<0.6 and 1 GeV^2<Q^2<10 GeV^2. Polarized quark distributions are extracted as a function of x for up $(u+u_bar) and down (d+d_bar) flavors. The up quark polarization is positive and the down quark polarization is negative in the measured range. The polarization of the sea is compatible with zero. The first moments of the polarized quark distributions are presented. The isospin non-singlet combination Delta_q_3 is consistent with the prediction based on the Bjorken sum rule. The moments of the polarized quark distributions are compared to predictions based on SU(3)_f flavor symmetry and to a prediction from lattice QCD.Comment: 14 pages, 6 figures (eps format), 10 tables in Latex New version contains tables of asymmetries and correlation matri

The HERMES Spectrometer

The HERMES experiment is collecting data on inclusive and semi-inclusive deep inelastic scattering of polarised positrons from polarised targets of Il, D, and He-3. These data give information on the spin structure of the nucleon. This paper describes the forward angle spectrometer built for this purpose. The spectrometer includes numerous tracking chambers (micro-strip gas chambers, drift and proportional chambers) in front of and behind a 1.3 T.m magnetic field, as well as an extensive set of detectors for particle identification (a lead-glass calorimeter, a pre-shower detector, a transition radiation detector, and a threshold Cherenkov detector). Two of the main features of the spectrometer are its good acceptance and identification of both positrons and hadrons, in particular pions. These characteristics, together with the purity of the targets, are allowing HERMES to make unique contributions to the understanding of how the spins of the quarks contribute to the spin of the nucleon.

Conformation and self-association of peptide amphiphiles based on the KTTKS collagen sequence

Studying peptide amphiphiles (PAs), we investigate the influence of alkyl chain length on the aggregation behavior of the collagen-derived peptide KTTKS with applications ranging from antiwrinkle cosmetic creams to potential uses in regenerative medicine. We have studied synthetic peptides amphiphiles C14− KTTKS (myristoyl Lys-Thr-Thr-Lys-Ser) and C18−KTTKS(stearoyl-Lys-Thr Thr-Lys-Ser) to investigate in detail their physicochemical properties. It is presumed that the hydrophobic chain in these self-assembling peptide amphiphiles enhances peptide permeation across the skin compared to KTTKS alone. Subsequently Cn−KTTKS should act as a prodrug and release the peptide by enzymatic cleavage. Our results should be useful in the further development of molecules with collagen-stimulating activity
