Neuentwicklung einer rollengelagerten Zahnradpumpe
Authors: Kremer H. 
Published: March 2008

AbstractSeit Jahrzehnten werden Zahnradpumpen für eine Vielzahl unterschiedlichster Anwendungen in der Industrie eingesetzt. Üblicherweise kommen dabei produktgeschmierte Gleitlager zum Einsatz. Zahnradpumpen mit einer externen, nicht produktgeschmierten Lagerung sind selten. Auch wenn diese Ausführung den großen Vorteil bietet, dass die Lagerschmierung vom Fördermedium und dessen Eigenschaften unabhängig ist, überwog bislang der Nachteil des deutlich niedrigeren Differenzdrucks. In dieser Arbeit wird eine Neukonstruktion im Detail vorgestellt, wobei speziell auf deren Sonderkonstruktion der Gleitringdichtung eingegangen wird. Abschließend werden dem Anwender verschiedene Möglichkeiten aufgezeigt, die sich aus dieser neuartigen Konstruktion ergeben. Insbesondere für hochgefüllte, abrasive und in anderer Weise schlecht schmierende Fördermedien stellt diese Art der Wellenlagerung eine Alternative zu bislang eingesetzten produktgeschmierten Gleitlagern dar.
Die Förderung von Flüssigkeiten mit Feststoffanteilen in magnetgetriebenen Kunststoffkreiselpumpen
Authors: Müller G. 
Published: March 2008

AbstractBei der Förderung von Medien mit magnetgetriebenen Kreiselpumpen wird im Regelfall von feststofffreien Flüssigkeiten ausgegangen. In der Praxis sind Medien jedoch oft mit Feststoffen beladen. Bei den Feststoffen kann es sich um Kristallisationen, Verschmutzungen oder gewollte Beifügungen verschiedenster Menge, Größe und Härte handeln. Die Vorteile magnetgetriebener Kreiselpumpen gegenüber direkt angetriebenen Pumpen sind vor allem die flexible Lagerung der Magnetkapsel sowie eine hermetisch dichte Konstruktion; dagegen kommt es aber sehr häufig zu Beschädigungen beim Einsatz von abrasiven Medien und somit zu Leckagen an der Gleitringdichtung. Es gibt keine formelmäßige Erfassung der vorhandenen Parameter Korngröße, Härte und Menge, aus der direkt abgeleitet werden kann, wie gut und wie lange eine magnetgekuppelte Kreiselpumpe funktionieren wird. Die Praxis zeigt, dass anhand verschiedener Maßnahmen und durch einen intensiven Erfahrungsaustausch mit dem Betreiber die Lebensdauer positiv beeinflusst werden kann.

Crystal growth, morphology, spectrographic characterization and thermal properties of 4,5‐bis(benzoylthio)‐1,3‐dithiole‐2‐thione
Authors: Wang Xinqiang , Xu Dong , Zhang Guanghui , Ren Quan , Liu Weiliang 
Published: March 2008

AbstractSingle crystals of 4,5‐bis(benzoylthio)‐1,3‐dithiole‐2‐thione (BBDT), were grown from methylene chloride and the growth morphology was deduced by the Bravais–Friedel Donnay–Harker (BFDH) model. The grown crystals were characterized by optical absorption, infrared, Raman and X‐ray powder diffraction spectroscopy. The thermal behavior of BBDT has been investigated by means of thermogravimetric analysis and differential thermal analysis measurements in air. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Synthesis and crystal strcucture of two zinc inclusion complexes
Authors: Han Min‐Le , Mi Li‐Wei , Chen Wei‐Hua 
Published: March 2008

AbstractX‐ray single crystals of these two inclusion complexes, [Zn(H2O)4L2]·(4‐amino‐1‐naphthalene sulfonate)2 (L = 1,3‐bis(4‐pyridyl) propane), 1, and [Zn(H2O)(bipy)2]·(4‐amino‐1‐naphthalene sulfonate)(NO3) (bipy = 4,4'‐bipyridine), 2 were achieved by the reaction of Zn(NO3)2 and 4‐amino‐1‐naphthalene sulfonate to 1,3‐bis(4‐pyridyl) propane and 4,4'‐bipyridine, respectively. As inclusion complexes, the cationic components of 1 and 2 were formed by two infinite zigzag chains, while, 4‐amino‐1‐naphthalene sulfonate made up the anionic parts of these two complexes. Thus, the whole molecules of these two complexes are neuter. Numous hydrogen bonds could be found in these two inclusion complexes, which help them to form three‐dimensional solid‐state packing structure architectures. (© 2008 WILEY‐VCH Verlag GmbH & Co.

Nonlinear optical properties of strontium tartrato‐antimonate(III) dihydrate, Sr[Sb2{(+)‐C4H2O6}2]·2H2O
Authors: Bayarjargal L. , Becker P. , Bohatý L. 
Published: March 2008

AbstractThe tensor of nonlinear optical susceptibility for second harmonic generation [dSHG ijk ] of hexagonal (point group 6) strontium tartrato‐antimonate(III) dihydrate, Sr[Sb2{(+)‐C4H2O6}2]·2H2O, was determined using the Maker fringes method and a Nd:YAG laser with a wavelength of 1064 nm. The largest component of the tensor dSHG 333 amounts two times dSHG 111 of α‐quartz. Effective nonlinear optical susceptibility dSHG eff is given for phase matching type I for several wavelengths (for type II dSHG eff is nearly zero). The thermal stability of crystals of Sr[Sb2{(+)‐C4H2O6}2]·2H2O was determined in the temperature range from 153 K to 573 K by means of thermal expansion measurements and thermogravimetry. The temperature dependence of thermal expansion coefficients is given in the range from 153 K to 293 K. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
PARP activation and the alteration of vasoactive factors and extracellular matrix protein in retina and kidney in diabetes
Authors: Xu Bingying , Chiu Jane , Feng Biao , Chen Shali , Chakrabarti Subrata 
Published: March 2008

AbstractAimsThe development of diabetic complications is associated with increased oxidative stress which may damage DNA leading to the activation of nuclear enzyme poly (ADP‐ribose) polymerase (PARP). PARP overactivation may further exacerbate the oxidative state of the cell through its consumption of nicotinamide adenine dinucleotide. In diabetic retinopathy and nephropathy, early characteristic features include increased production of vasoactive factors such as endothelin 1 (ET‐1) and increased synthesis of extracellular matrix (ECM) proteins such as fibronectin (FN) and its splice variant extra domain B containing (EDB+) FN. We investigated the role of PARP in the development of diabetic retinopathy and nephropathy.MethodsTwo models of diabetic complications were used. PARP‐1 knockout mice and their respective wild type controls were fed a 30% galactose diet for 2 months. The rats were given injections of PARP inhibitor 3‐aminobenzamide (30 mg/kg/day).ResultsAnalysis of the retinal and kidney tissues showed hyperhexosemia‐induced oxidative stress and increased expression of ET‐1, FN and EDB+ FN in association with increased transcriptional co‐activator p300 along with p300‐dependent transcription factors, myocyte enhancing factors 2A and 2C. Furthermore, we showed increased PARP expression in the kidneys and retina of the diabetic rats. PARP blockade in both animal models prevented these hyperhexosemia‐induced effects.ConclusionsThese findings suggests that hyperhexosemia and diabetes causes upregulation of ET‐1, FN and EDB+ FN at the transcriptional level in the retina and kidney via a signaling pathway mediated by PARP and an epigenetic mechanism involving p300 and MEF2 transcription factors. Understanding these mechanisms is important in identifying novel treatment targets. Copyright © 2008 John Wiley & Sons, Ltd.
Microarray analysis of striatal embryonic stem cells induced to differentiate by ensheathing cell conditioned media

Published: March 2008

AbstractThe mammalian central nervous system contains well‐defined regions of plasticity in which cells of the aldynoglia phenotype promote neuronal growth and regeneration. Only now are the factors that regulate the production of new cells from multipotential neural precursors (MNP) starting to be identified. We are interested in understanding how differentiation towards the aldynoglia phenotype is controlled, and to study these events we have induced the differentiation of embryonic MNP towards this phenotype in vitro. Accordingly, we have used microarrays to analyze gene expression in three different cell populations: olfactory bulb ensheathing cells (EC), a prototypic aldynoglia cell type; undifferentiated MNP; and MNP differentiated in vitro for 24 hr in EC‐conditioned media. The expression profiles identified support the idea that the EC are more closely related to Schwann cells and astrocytes than to oligodendrocytes. Following MNP differentiation, more strongly expressed genes define a neuroglial cell phenotype. RT‐PCR confirms that S100a6, Mtmr2, and Col5a were highly expressed by EC, whereas Pou3f3 were more strongly expressed in MNP than in EC, and SafB1 and Mash1 expression were induced in MNP by EC‐conditioned media. The profile of gene expression after differentiation suggests that Wnt signaling may be inactivated during this process, while activation of the BMP pathway may be elicited through the BMPr1A. These results provide us with a starting point to study the genes involved in the induction of aldynoglia differentiation from MNP. Developmental Dynamics 237:979–994, 2008. © 2008 Wiley‐Liss, Inc.
Ultrasound‐guided in utero injections allow studies of the development and function of the eye
Authors: Punzo Claudio , Cepko Constance L. 
Published: March 2008

AbstractUltrasound‐guided in utero injections into the brain of murine embryos has been shown to facilitate gene delivery. We investigated whether these methods would allow gene transfer into ocular structures. Gene transfer using retroviral vectors or electroporation was found to be quite effective. We determined the window of time, as well as compared several strains of mice, that yield a high degree of survival and successful gene transfer. Several retroviral constructs were tested for expression and coexpresssion of two genes in retinal cell types. In addition, a retroviral vector was engineered to give cone photoreceptor‐enriched expression, and a retroviral vector was demonstrated to provide RNAi‐mediated loss‐of‐function. These methods enable access to early ocular structures and provide a more rapid method of assessment of gene and promoter function than possible using genetically engineered mice.

Expression of the NET family member Zfp503 is regulated by hedgehog and BMP signaling in the limb

Published: March 2008

AbstractThe NET/Nlz family of zinc finger transcription factors contribute to aspects of developmental growth and patterning across evolutionarily diverse species. To date, however, these molecules remain largely uncharacterized in mouse and chick. We previously reported that limb bud expression of Zfp503, the mouse orthologue of zebrafish nlz2/znf503, is dependent on Gli3. Here, we show that Zfp503/Znf503 is expressed in a restricted pattern during mouse and chick embryogenesis, with particularly dynamic expression in the developing limbs, face, somites, and brain. We also add to our previous data on Gli3 regulation by showing that the anterior domain of Zfp503 expression in the mouse limb is responsive to genetic and nongenetic manipulation of hedgehog signaling. Finally, we demonstrate that posterior expression of Znf503 in the chick limb is responsive to bone morphogenetic protein (BMP) signaling, indicating that Zfp503/Znf503 may act at the nexus of multiple signaling pathways in development.

WNT signaling affects gene expression in the ventral diencephalon and pituitary gland growth

Published: March 2008

AbstractWe examined the role of WNT signaling in pituitary development by characterizing the pituitary phenotype of three WNT knockout mice and assessing the expression of WNT pathway components. Wnt5a mutants have expanded domains of Fgf10 and bone morphogenetic protein expression in the ventral diencephalon and a reduced domain of LHX3 expression in Rathke's pouch. Wnt4 mutants have mildly reduced cell differentiation, reduced POU1F1 expression, and mild anterior lobe hypoplasia. Wnt4, Wnt5a double mutants exhibit an additive pituitary phenotype of dysmorphology and mild hypoplasia. Wnt6 mutants have no obvious pituitary phenotype. We surveyed WNT expression and identified transcripts for numerous Wnts, Frizzleds, and downstream pathway members in the pituitary and ventral diencephalon. These findings support the emerging model that WNT signaling affects the pituitary gland via effects on ventral diencephalon signaling, and suggest additional Wnt genes that are worthy of functional studies.

AbstractTwo 2D Anderson polyoxomolybdate‐based compounds, [{Ni(H2O)4}2{Ni(OH)6Mo6O18}]·4H2O (1) and [Ni(H2O)6][Ag2{Ni(OH)6Mo6O18}]·8H2O (2), were synthesized and characterized by elemental analysis, IR spectroscopy, SEM, and single‐crystal XRD. Their thermal behavior was studied by TGA, DSC, XRTD, and IR spectroscopy. Both 1 and 2 are arranged in 2D networks. In 1, [Ni(OH)6Mo6O18]4– Anderson units are covalently linked to each other by two different types of Ni2+, whereas in 2, the corresponding interactions are ensured exclusively by Ag+ ions. In addition, all the Ni2+ cations in 2 are located in interplanar positions and act selectively as counterions. Upon the addition of silver, the thermal stability of the Anderson anion is increased from 170 °C for pure nickel compound 1 up to 220 °C for mixed silver–nickel 2. Below 220 °C, 2 exhibits reversible hydration–dehydration processes with preservation of the Anderson anion structure. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)

Published: March 2008

AbstractThe reaction of the ligand 1,4‐bis(pyridine‐2‐carboxamido)butane (L) with RECl3 afforded complexes of general formula [RE(L)1.5Cl2(CH3OH)]Cl·nS (RE = Pr, Nd, Eu, Tb; n = 4, S = H2O; n = 5, S = CH3OH). The structural determination reveals that complexes [RE(L)1.5Cl2(CH3OH)]Cl·5CH3OH (RE = Nd 2b, Eu 3b) are isomorphous, crystallizing in the monoclinic system, space group P21/n; they possess a 2D architecture with the rare‐earth ion in an eight‐coordination geometry. By exposure to air, the lattice methanol molecules are easily replaced by water molecules to form the analogues [RE(L)1.5Cl2(CH3OH)]Cl·4H2O (RE = Pr 1, Nd 2a, Eu 3a, Tb 4) as indicated by elemental analysis, IR, and thermogravimetric analysis. Photophysical studies on the EuIII and TbIII complexes showed that excitation into the ligand‐centered π→π* transition results in the characteristic visible luminescence from EuIII at 614 nm and TbIII at 545 nm. The magnetic properties were also investigated and show that crystal field effects are dominant. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
Structure and Properties of NaBH4·2H2O and NaBH4
Authors: Filinchuk Yaroslav , Hagemann Hans 
Published: March 2008

AbstractNaBH4·2H2O and NaBH4 were studied by single‐crystal X‐ray diffraction and vibrational spectroscopy. In NaBH4·2H2O, the BH4– anion has a nearly ideal tetrahedral geometry and is bridged with two Na+ ions through the tetrahedral edges. The structure does not contain classical hydrogen bonds, but reveals strong dihydrogen bonds of 1.77–1.95 Å. Crystal structures and vibrational spectra of NaBr·2H2O and NaBH4·2H2O reveal many similarities. The unit cell volume of NaBH4·2H2O increases linearly with temperature between 200 and 313 K. At 313–315 K, the hydrate decomposes into NaBH4 and H2O, which react to release hydrogen.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)

The Steensby Inlet Ice Stream in the context of the deglaciation of Northern Baffin Island, Eastern Arctic Canada
Authors: Dyke Arthur S. 
Published: March 2008

AbstractDeglaciation of northern Baffin Island involved several large ice streams with contrasting histories. Three north‐flowing, marine‐based ice streams were in place during the Last Glacial Maximum, but they retreated at widely varying rates during the early and middle Holocene. The Steensby Inlet Ice Stream formed in response to over‐steepening of the ice front during deglaciation of Foxe Basin. It caused an abrupt change, in places a general reversal, of flow about 6 ka BP and operated across its full width for only about 500 years. Nevertheless, it left a distinct subglacial footprint, including an hourglass shaped bedform set. A dense network of till samples from the region of the ice stream reveals a sharp‐sided, pluglike dispersal of carbonate debris that was sustained by erosion in the source area of about 5 mm a−1. The ice stream devolved into valley‐controlled ice streams separated by cold‐based ice over interfluves. The former evacuated debris along valleys and left erosional till scarps along the sides of sliding ice. Post‐ice‐stream end moraines, including the large Gifford Moraine, require later cold‐based flow across the drumlins formed by the ice stream. Copyright © 2008 John Wiley & Sons, Ltd.
