No full textThis is a PSYNDEX Tests Review of BDI-FS - Beck Depressions-Inventar - FS. PSYNDEX Tests Reviews are written in German and describe and evaluate psychological and educational tests used in the German-speaking countries. PSYNDEX Tests is offered by the Leibniz Institute for Psychology as open access documentation.Das ist ein PSYNDEX Tests Review zu BDI-FS - Beck Depressions-Inventar - FS. PSYNDEX Tests Reviews beschreiben und bewerten zentrale psychologische und pädagogische Testverfahren, die in den deutschsprachigen Ländern eingesetzt werden, nach einem standardisierten Raster. PSYNDEX Tests wird durch das Leibniz-Institut für Psychologie als Open Access Dokumentation angeboten.Diagnostische Zielsetzung: Mit dem Beck Depressions-Inventar - Fast Screen (BDI-FS) kann ein Depressionsscreening bei Jugendlichen und Erwachsenen im Einzelsetting durchgeführt werden. Das BDI-FS kann in Praxen, Krankenhäusern, im Bereich der Geriatrie sowie in der Altenversorgung zur Erfassung der nicht-somatischen Symptome verwendet werden - problemlos auch bei Patienten mit somatischen Beschwerden. Aufbau: Der BDI-FS umfasst sieben Aussagegruppen, die der Langform entnommen wurden: (1) Traurigkeit, (2) Pessimismus, (3) Versagensgefühle, (4) Verlust an Freude, (5) Selbstablehnung, (6) Selbstkritik und (7) Suizidgedanken. Jede Aufgabengruppe umfasst vier Antwortalternativen. Grundlagen und Konstruktion: Der BDI-FS wurde aufbauend auf einer kognitiv-affektiven Subskala des BDI konstruiert, welche bei der Untersuchung von Patienten mit somatischen Grunderkrankungen oder Süchten eingesetzt werden sollte. Die Items des BDI-II wurden auf Grundlage inhaltlicher Überlegungen und faktorenanalytischer Untersuchungen (Kriterium: stärkste Faktorladungen) zur Konstruktion des Screeninginstruments aufgenommen. Die englische Originalversion BDI-FS wurde im Jahre 2000 veröffentlicht. Die mittlere Schwierigkeit beträgt P = 5.43 und die Trennschärfekoeffizienten der Items liegen zwischen rit = .47 (Suizidgedanken) und .69 (Pessimismus). Empirische Prüfung und Gütekriterien: Reliabilität: Die interne Konsistenz des Verfahrens in einer deutschsprachigen repräsentativen Stichprobe liegt bei Cronbachs Alpha = .84 (n = 2510). Validität: Die konvergente Validität des deutschsprachigen BDI-FS wurde nachgewiesen durch positive Korrelationen mit den Werten des Depressionsinventares PHQ-9 (r = .67). Die diskriminante Validität wurde aufgezeigt durch Korrelationen des BDI-FS mit einem Angstinventar sowie einem Inventar zur Erfassung körperlicher Symptome (r = .60 bzw. r = .57). Das Verfahren ist gemäß den Ergebnissen einer Faktorenanalyse eindimensional. Normen: Es liegen bevölkerungsrepräsentative Normen in Form von Prozenträngen und T-Werten für drei Altersgruppen, Frauen und Männer getrennt sowie für die Gesamtstichprobe vor, die an N = 2 467 deutschen Probanden (53% weiblich, 47 männlich; Altersdurchschnitt: M = 49.4, SD = 18.0) gewonnen wurden.publishedVersio
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
Yb-doped femtosecond lasers and their frequency doubling
No full textUltralow threshold, compact and highly efficient femtosecond lasers based on Yb³⁺-doped
potassium yttrium tungstate (Yb:KYW) and Yb³⁺-doped vanadium yttrium oxide
(Yb:YVO 4 ) have been demonstrated within this PhD-research project. For a continuous
wave unmode-locked Yb:KYW laser a threshold as low as 101 mW was obtained with a
slope efficiency of 74%. By employing a single prism for dispersion control, the laser was
tunable between 1012 nm to 1069 nm. When operated in the mode-locked regime, this
laser produced transform-limited pulses having durations of 210 fs at a central wavelength
of 1044 nm. Stable mode locking was observed for an optimised incident pulse fluence on
the SESAM between 140 μJ/cm²
to 160 μJ/cm²
which was 2-3 times higher than the
designed energy pulse fluence of the SESAM (70 μJ/cm²).
The employment of several combinations of chirped mirror designs for control of
intracavity group velocity dispersion led to excellent results. The threshold for mode
locking was satisfied for a pump power of 255 mW where the slope efficiency was
measured to be 62%. This is the most efficient SESAM-assisted femtosecond laser yet
reported and the highest optical-to-optical efficiency of 37% is exceptional. Transform-limited pulses with durations as short as 90 fs were produced in a spectral region centred
on 1052 nm. The success of this research thus represents a good foundation on which to
design and build more compact configurations that will incorporate just one chirped mirror
for dispersion compensation.
A relatively high nonlinear refractive index, n₂ , of 15 x 10⁻¹⁶ cm²/W was measured
in Yb:YVO₄ and this affords particular potential for this candidate material in Kerr-lens
mode locking. In fact, for operation in the femtosecond domain, the threshold power was
190 mW with a slope efficiency of 26% and near-transform-limited pulses as short as 61fs were generated at a centre wavelength of 1050 nm. The main objectives in developing
this type of laser relate to a demonstration of high peak power operation in thin disc laser
configurations.
The deployment of a diode-pumped Yb:KYW femtosecond laser as a pump source
for frequency doubling in a periodically-poled LiTaO₃ crystal was realised. The maximum
realized output power of 150 mW corresponded to an impressive second harmonic
conversion efficiency of 43%. 225-fs duration green pulses (centred at 525 nm) were
generated under the condition of strong focusing in the nonlinear crystal

RV Ronald H. Brown Cruise RB0701, 21 Mar-10 Apr 2007. RAPID mooring cruise report
No full textThis report describes the mooring operations conducted during RV Ronald H. Brown Cruise RB0701 conductedbetween 21 March 2007 and 10 April 2007.These mooring operations were completed as part of the United Kingdom Natural Environment Research Council(NERC) funded RAPID Programme to monitor the Atlantic Meridional Overturning Circulation at 26.5ºN. Theprimary purpose of this cruise was to service the Western Boundary section of the 26.5ºN mooring array firstdeployed in 2004 during RRS Discovery cruises D277 and D278 (SOC cruise report number 53), and serviced in2005 during RRS Charles Darwin Cruise CD170 and RV Knorr Cruise KN182-2 (NOCS cruise report number 2),RRS Charles Darwin Cruise CD177 (NOCS cruise report number 5), and in 2006 on RV Ronald H. Brown CruiseRB0602, RRS Discovery Cruise D304 (NOCS cruise report number 16) and FS Poseidon Cruises P343 and P345(NOCS cruise report number 28).Cruise RB0701 was from Charleston, SC to San Juan, Puerto Rico, and covered the Western Boundary mooringsdeployed on RB0602 (along with two landers deployed on KN182-2). This cruise is the third annual refurbishmentof the Western Boundary section of an array of moorings deployed across the Atlantic in order to set up a preoperationalprototype system to continuously observe the Atlantic Meridional Overturning Circulation (MOC).This array will be further refined and refurbished during subsequent years.The instrumentation deployed on the array consists of a variety of current meters, bottom pressure recorders, CTDloggers and Inverted Echosounders, which, combined with time series measurements of the Florida ChannelCurrent and wind stress estimates, will be used to determine the strength and structure of the MOC at 26.5ºN.(http://www.noc.soton.ac.uk/rapidmoc
Tissue architecture of the anterior pituitary showing the epithelial cell cords with hormonal cells and folliculo-stellate (FS) cells, the capillaries (C) with fenestrated endothelial cells (EC) and connective tissue (CT)

Journal Compilation © 2008 Blackwell Publishing Ltd</p> The cell cords are a cluster of endocrine cells surrounding an aggregate of FS cells that make a follicle (F). FS cells also make a meshwork between the hormonal cells, making junctions among each other (thick lines) and extending foot processes (f) ending on the basal membrane (BM) in the periphery of the cord. The cords are surrounded by BM, which may have extensions between some cells. A second BM surrounds the capillary vessels and between these two some connective tissue resides. Small and larger lacunae are present between hormonal cells. Paracrine substances may circulate from cell-to-cell but also could be released in these lacunae and reach more remote places. FS cells make gap junctions mostly among each other, but occasionally also with some hormonal cells. Hormonal cells can make interdigitations with FS cells (small arrows) to favour cell-to-cell communication. Adapted from Vila-Porcile ()
Fearon Teacher Aids
No full textThis book seems to follow upon but not to duplicate the materials in Fables and Tales Papercrafts in the same series from 1989. The publisher and place have changed to Simon & Schuster and Carthage, IL, from David S. Lake Publishers in Belmont, CA. This book contains ten stories. Like the earlier book, it presents a full page to be colored for each story. Then there are clever opportunities for making sculptures, puppets, and masks. It contains three Aesopic fables at its end: TMCM, FS, and GA. The jointed puppets for FS look particularly attractive. Strangely, the book seems never to tell the stories.Jerome C. Brow
Adaptive pulse compression for transform-limited 15-fs high-energy pulse generation
No full textWe demonstrate the use of a deformable-mirror pulse shaper, combined with an evolutionary optimization algorithm, to correct high-order residual phase aberrations in a 1-mJ, 1-kHz, 15-fs laser amplifier. Frequency resolved optical gating measurements reveal that the output pulse duration of 15.2 fs is within our measurement error of the theoretical transform limit. This technique significantly reduces the pulse duration and the temporal prepulse energy of the pulse while increasing the peak intensity by 26%. It is demonstrated, for what is believed to be the first time, that the problem of pedestals in laser amplifiers can be addressed by spectral-domain correction
Fluvastatin Sodium Ameliorates Obesity through Brown Fat Activation
No full textBrown adipose tissue (BAT), an organ that burns energy through uncoupling thermogenesis, is a promising therapeutic target for obesity. However, there are still no safe anti-obesity drugs that target BAT in the market. In the current study, we performed large scale screening of 636 compounds which were approved by Food and Drug Administration (FDA) to find drugs that could significantly increase uncoupling protein 1 (UCP1) mRNA expression by real-time PCR. Among those UCP1 activators, most of them were antibiotics or carcinogenic compounds. We paid particular attention to fluvastatin sodium (FS), because as an inhibitor of the cellular hydroxymethyl glutaryl coenzyme A (HMG-CoA) reductase, FS has already been approved for treatment of hypercholesteremia. We found that in the cellular levels, FS treatment significantly increased UCP1 expression and BAT activity in human brown adipocytes. Consistently, the expression of oxidative phosphorylation-related genes was significantly increased upon FS treatment without differences in adipogenic gene expression. Furthermore, FS treatment resisted to high-fat diet (HFD)-induced body weight gain by activating BAT in the mice model. In addition, administration of FS significantly increased energy expenditure, improved glucose homeostasis and ameliorated hepatic steatosis. Furthermore, we reveal that FS induced browning in subcutaneous white adipose tissue (sWAT) known to have a beneficial effect on energy metabolism. Taken together, our results clearly demonstrate that as an effective BAT activator, FS may have great potential for treatment of obesity and related metabolic disorders
Evaluation Of Recoverable Functional Lipid Components of Several Brown Seaweeds (Phaeophyta) From Japan with Special Reference to Fucoxanthin and Fucosterol Contents
No full textFucoxanthin (Fx) and fucosterol (Fs) are characteristic
lipid components of brown seaweeds that afford several health benefits to humans. This article describes the quantitative evaluation of lipids of 15 species of brown seaweeds with specific reference to Fx, Fs, and functional long-chain omega- 6 ⁄ omega-3 polyunsaturated fatty acids (PUFAs). In addition, fatty-acid composition of selected species was also accomplished in the study. Major omega-3
PUFAs in the brown seaweeds analyzed were a-linolenic
acid (18:3n-3), octadecatetraenoic acid (18:4n-3), arachidonic acid (20:4n-6), and eicosapentaenoic
acid (20:5n-3). Both Fx (mg Æ g)1 dry weight [dwt])
and Fs (mg Æ g)1 dwt) were determined to be relatively
abundant in Sargassum horneri (Turner) C. Agardh (Fx, 3.7 ± 1.6; Fs, 13.4 ± 4.4) and Cystoseira hakodatensis (Yendo) Fensholt (Fx, 2.4 ± 0.9; Fs, 8.9 ± 2.0), as compared with other brown seaweed species. Studies related to seasonal variation in Fx, Fs, and total lipids of six brown algae [S. horneri, C. hakodatensis, Sargassum fusiforme (Harv.) Setch., Sargassum thunbergii (Mertens ex Roth) Kuntze,
Analipus japonicus (Harv.) M. J. Wynne, and Melanosiphon
intestinalis (D. A. Saunders) M. J. Wynne] indicated
that these functional lipid components reached maximum during the period between January and March. The functional lipid components present in these seaweeds have the potential for application as nutraceuticals and novel functional ingredients after their recovery
