Authors: Camur‐Elipek Belgin , Arslan Naime , Kirgiz Timur , Oterler Burak 
Published: August 2006

AbstractThe numerical and proportional distributions of benthic macroinvertebrates in Tunca (Tundja, Tundzha) River (Edirne/Turkey) were determined from July 2002 to June 2003 at monthly intervals at four different stations. It was found that the benthic macrofauna consisted of 63% Oligochaeta, 24% Chironomidae larvae, and 13% Varia by numbers. According to the Shannon‐Wiener index, Tunca River had a diversity of 1.36; station 2 and September were found to have the highest diversity while station 4 and December to have the poorest. According to Bray‐Curtis similarity index, stations 2 and 3 and April and May were found to be the most similar to each other while stations 1 and 4 and August and January were found to be the most different from each other for the dynamics of the benthic macrofauna. Also some physicochemical parameters of the water (water temperature, electrical conductivity, pH, dissolved oxygen, chloride, total hardness, NO3–‐N, NO2–‐N, sulfate, phosphate, biochemical and chemical oxygen demands) were analyzed. Pearson correlation index supported the relationships between the dynamics of organisms and physicochemical variables. The relation between the number of macroinvertebrates and pH (r = +0.57, P < 0.05) was direct proportional while the relation between the number of macroinvertebrates and NO3–‐N (r = –0.99, P < 0.05) was inverse proportional. Furthermore, the Chironomidae larvae of Bryophaenocladius muscicola and Mesosmittia flexuella were new records for Turkish Thrace region. High pH and supersaturated oxygen levels, hard water quality, second quality levels of NO3–‐N, BOD, COD and fourth quality levels of NO2–‐N as well as the density of 490 individuals m–2 for 124 taxa and the diversity of 1.36 showed that similar studies should be repeated periodically in Tunca to determine the future of the river.
Molecular implications of hydrophobic organic partitioning theory
Authors: Christman Russell F. , Pfaender Frederic K. 
Published: August 2006

AbstractRecent normal phase silica followed by reverse phase XAD separation has led to the identification of several flavonoid and condensed tannin structures in Suwannee River Fulvic Acid (SFRA) (Leenheer, J. A., Rostad, C. (2004) Scientific Investigations Report 2004–5276, U.S. Geological Survey). We have used the molecular properties of one of these structures to define ideal behavior during partitioning of PAHs assuming that these structures function as an immiscible liquid solvent bound to finely dispersed mineral particles. Existing data for the partitioning of PAHs into NOM compared well to this ideal behavior under Raoult/Henry and Flory‐Huggins treatments, and activity coefficients of pyrene in the hypothetical NOM phase and the free energy of transfer were estimated. If experimental data on partitioning of PAHs into synthesized samples of these structures is similar to NOM uptake data, it will be attractive to assume that, a) much smaller components of the NOM complex than suggested by gross molecular weight may be important in environmental properties such as solubility enhancement, and b) the effective molar volumes within the NOM complex responsible for solubility enhancement may be solute, or solute class dependent.

Authors: Maidl Bernhard , Maidl Ulrich 
Published: August 2006

AbstractVerkehrstunnel in verkarsteten Gebirgen sind eine besondere Herausforderung an alle am Bau Beteiligten. Wenn dazu noch die Bedingungen einer Hochgeschwindigkeitsstrecke mit fester Fahrbahn kommen, werden die Anforderungen um ein Vielfaches erhöht. Die Vorgehensweise und die getroffenen Maßnahmen zur Gewährleistung einer sicheren Erstellung der Bauwerke und einer dauerhaften Gebrauchsfähigkeit des Verkehrswegs sind Gegenstand dieses Beitrags. Die dargelegte Vorgehensweise wurde am Irlahülltunnel auf der Neubaustrecke Nürnberg–Ingolstadt der Deutschen Bahn AG praktiziert und ist auf andere Verkehrswege in karstgefährdeten Gebieten übertragbar. Im Beitrag wird auf ein mittlerweile umfangreiches Literaturgut, das jeweils zitiert wird, zurückgegriffen, wobei der Vortrag Pöttler, R.; Maidl, R. [1] als Grundlage dient.

Authors: Rug Wolfgang 
Published: August 2006

AbstractDer Zimmermeister Otto Hetzer aus Weimar erhielt auf die Erfindung eines gebogenen Holzbauteils am 22. 06. 1906 ein Patent. Das gebogene Holzbauteil sollte aus zwei oder mehreren Langholzstäben bestehen, die durch Zwischenfügen eines Klebstoffes zu einem Bauteil verklebt waren. Das neue Konstruktionsprinzip hatte zahlreiche Vorteile wie z. B. die Herstellung beliebig geformter Tragwerke, die Unabhängigkeit vom aus dem Stamm gewinnbaren Holzquerschnitt und die Herstellung statisch günstiger Querschnitte. Dieses Patent hat den Holzbau in den letzten 100 Jahren grundlegend verändert.

Published: August 2006

AbstractDas Grüne Tor in Danzig ist ein Baudenkmal aus dem 16. Jahrhundert. Die Tragkonstruktion besteht aus gemauerten Wänden und Säulen, die auf einem Holz‐Trägerrost auf Holzpfählen gegründet ist. Von fünf oberirdischen Stockwerken befinden sich drei im Bereich eines steilen Ziegeldachs, dessen tragende Konstruktion aus Holz und mittlerweile Stahlbeton besteht. In den Jahrhunderten seines Bestehens wurde das Gebäude mehrmals wiederauf‐ und umgebaut. Der Zustand vor dem Teil einsturz im Januar 2002 stammte aus den fünfziger Jahren des 20. Jahrhunderts. Damals wurde das Gebäude nach den Schäden aus dem 2. Weltkrieg wiederaufgebaut.Die Katastrophe zerstörte die freistehende Steinsäule samt dem Ziegelgewölbe, das darauf gestützt war. In diesem Beitrag werden die Ursache der Katastrophe und die Art und Weise des Wiederaufbaus des zerstörten Gebäudefragmentes beschrieben. In groben Zügen wird auch die Konzeption der Rekonstruktion des ganzen Gebäudes behandelt, darin hauptsächlich der tragenden Konstruktion der Gewölbe, der Decken zwischen den Stockwerken und des Dachs.
Jet‐based methods to print living cells
Authors: Ringeisen Bradley R. , Othon Christina M. , Barron Jason A. , Young Daniel , Spargo Barry J. 
Published: August 2006

AbstractCell printing has been popularized over the past few years as a revolutionary advance in tissue engineering has potentially enabled heterogeneous 3‐D scaffolds to be built cell‐by‐cell. This review article summarizes the state‐of‐the‐art cell printing techniques that utilize fluid jetting phenomena to deposit 2‐ and 3‐D patterns of living eukaryotic cells. There are four distinct categories of jetbased approaches to printing cells. Laser guidance direct write (LG DW) was the first reported technique to print viable cells by forming patterns of embryonic‐chick spinal‐cord cells on a glass slide (1999). Shortly after this, modified laser‐induced forward transfer techniques (LIFT) and modified ink jet printers were also used to print viable cells, followed by the most recent demonstration using an electrohydrodynamic jetting (EHDJ) method. The low cost of some of these printing technologies has spurred debate as to whether they could be used on a large scale to manufacture tissue and possibly even whole organs. This review summarizes the published results of these cell printers (cell viability, retained genotype and phenotype), and also includes a physical description of the various jetting processes with a discussion of the stresses and forces that may be encountered by cells during printing. We conclude the review by comparing and contrasting the different jet‐based techniques, while providing a map for future experiments that could lead to significant advances in the field of tissue engineering.
Declining medical decision‐making capacity in mild AD: a two‐year longitudinal study

Published: August 2006

AbstractThis is a report of a two‐year longitudinal study comparing healthy older adult subjects (n = 15) and mild Alzheimer's disease (AD) patients (n = 20) using an objective performance measure of medical decision‐making capacity (MDC). Capacity to consent to medical treatment was measured using the Capacity to Consent to Treatment Instrument (CCTI). The CCTI is a psychometric measure that tests MDC using a series of four core capacity standards: S1 (evidencing/communicating choice), S3 (appreciating consequences), S4 (providing rational reasons), and S5 (understanding treatment situation), and one experimental standard [S2] (making the reasonable treatment choice). For each standard, mild AD patients were assigned one of three capacity outcomes (capable, marginally capable, or incapable) based on cut‐off scores derived from control group performance.At baseline, mild AD patients performed equivalently with controls on simple standards of evidencing a choice (S1) and making the reasonable choice ([S2]), but significantly below controls on complex standards of appreciation, reasoning, and understanding (S3, S4, and S5) (p < 0.02). Control performance was stable over time on all capacity standards. At one‐year follow‐up, the mild AD group did not show significant decline from baseline on any capacity standard. However, at two‐year follow‐up the mild AD group showed significant declines from baseline on the three complex standards (S3, S4, and S5) (p < 0.02), and a trend on one of the simple standards (S1). Over the two‐year period, the proportion of marginally capable and incapable outcomes in the AD group increased substantially for four of the five standards (S1, S3, S4, and S5). Performance on [S2] remained stable over time in the AD group.We conclude that mild AD patients have impaired MDC at baseline, and demonstrate significant additional decline on complex consent abilities of appreciation, reasoning, and understanding over a two‐year period. AD patients also show emerging impairment on the simple consent ability of evidencing choice at two‐year follow‐up. Capacity outcome data reflect similar declines over time for these four consent standards. The findings suggest the value of early assessment and regular monitoring at two‐year intervals of MDC in patients with mild AD. Copyright © 2006 John Wiley & Sons, Ltd.
Synthesis of Functionalized Guanidino Amino Acids
Authors: Suhs Thomas , König Burkhard 
Published: August 2006

AbstractWe report the synthesis of guanidino amino acids (GuAA), which are structurally related to Arg and resemble a dipeptide consisting of α‐ and γ‐amino acid with a guanidinium group in the main chain. The compounds are available with different protecting groups in gram amounts and are intended as synthetic building blocks for the construction of synthetic oxoanion or peptide receptors. Tyr, Trp or dansyl‐functionalized Lys can be introduced as the α‐amino acid part, which leads to luminescent GuAAs. The compounds signal carboxylate binding in MeOH, DMSO and buffered water by change of the emission intensity. The property may find use in the construction of chemosensors.
