Portrait of Max Boehm.
No full textSitter wears a dark business suit, a ring on his right hand, the other holds a cigar. His posture is relaxed. Set against a warm, tan background.Herman Boehm (son)Max Boehm was a prominent liquor manufacturer, banker, real estate dealer, restaurateur, music patron and collector of German art. He died in the Concentration camp at Theresienstadt, Czechoslovakia. Boehm and Max Liebermann were closely associated and the collector's memoirs of this relationship, written in the camp, have survived. (See LBI Archives, AR 4154)Max Liebermann trained in Weimar before continuing to study in Amsterdam and Paris, where he was influenced by Courbet, Millet, and the Barbizon School. Liebermann returned to Germany in 1878 and continued painting in the Impressionist style, founding the movement in his native country. In 1899, he helped found the Berlin Secession. He was a very influential figure in German art and was the dominant figure until the emergence of avant-garde art. He was the president of the Prussian Academy of Arts but was forced to resign in 1933 because he was Jewish.Updated record.Digital imag
The painting "An Evening Song" by Max Ring, depicting a woman reading sheet music in a meadow, [s.d.]
No full textPhotograph of the painting "An Evening Song" by Max Ring, depicting a woman reading sheet music in a meadow, [s.d.]. The woman is shown in full figure at center, dressed in what appears to be a bridal gown. She tilts her head back and rolls her eyes to the sky, while holding a sheaf of sheet music in her hands, as well as a violin, which she carries by the neck. In the background, a clearing is visible, moving back towards thicker forest
A study of the ring opening metathesis polymerization of polycyclic aromatic monomers and cyclopentenes with well defined initiators
No full textThis thesis describes studies into the ring opening metathesis polymerisation (ROMP) of polycyclic aromatic monomers and cyclopentenes. Chapter 1 reviews general aspects of ring opening metathesis polymerisation of relevance to the themes of this thesis. Chapter 2 describes the synthesis of polycyclic aromatic monomers, the endo and the exo Diels-Alder adducts of acenaphthylene and cyclopentadiene. Chapter 3 reports a study on the polymerisation of these monomers using well defined initiators and classical catalyst systems. Chapter 4 describes the synthesis of a substituted cyclopentene. Chapter 5 reports an investigation of polymerisation of cyclopentene using a variety of well defined initiators of general formula M(=NAr)(- OR)(_2)(=CHR) where M=Mo or W. Chapter 6 presents a study on the polymerisation of a substituted cyclopentene, 4-methylcyclopentene, using a series of well defined initiators, and the characterisations of the polymers obtained using infrared, (^1)H, and (^13)C n.m.r. spectroscopy, differential scanning calorimetry, and gel permeation chromatography and an analysis of detailed microstructure with respect to meso/racemic configurations in the polymer chain. Finally, Chapter 7 summarises the conclusions and makes some suggestions for future work
Impedance and Instabilities in the MAX IV 3 GeV Ring
No full textTo ensure the beam with an ultralow emittance and high current the possible effects deteriorating the beam stability must be investigated. When ultrarelativistic particles travel in the vacuum chamber they induce electromagnetic fields which can act back on them and the following particles. The interaction of the beam with the surrounding environment can be described by wakefields in time domain and impedance in frequency domain. In this work the geometric and resistive wall impedance effects on the beam stability in the MAX IV 3 GeV ring are studied. The geometric impedance of different recurrent elements of the storage ring was numerically calculated using an electromagnetic field solver, and a possibility to use a semi-analytical method was investigated as well. To quantitatively evaluate the effect of geometric impedance on the beam stability the total machine impedance budget of the MAX IV 3 GeV ring was built and introduced into the beam dynamics simulation. The particle tracking code was developed to account for different possible effects impacting the beam, namely, geometric and resistive wall impedance and passive harmonic cavities that lengthen bunches and increase the synchrotron tune spread. The former helps to make the beam less influenced by the intrabeam scattering processes and the machine impedance, and the latter introduces the Landau damping of instabilities. The results of the particle tracking are discussed in this work. The presence of harmonic cavities in the MAX IV storage ring turned out to significantly improve the beam stability and to be the key in achieving the design parameters

The MAX-III storage ring
No full textMAX-III is a 700 MeV storage ring for synchrotron radiation that is being built at MAX-lab. The ring will provide radiation in the UV and IR spectral regions. The ring will have a 100 MHz RF system combined with a 500 MHz passive Landau cavity. The lattice is compact, with combined function magnets. The magnets are integrated into the girder providing for ease of alignment
RING finger protein 17 (Rnf17) of Myc/Max/Mxd network: expression and function during mouse reproduction and development
No full textThe preimplantation mammalian embryo is sensitive to the environment in which they develop and grow, either in vivo or in vitro. Disturbance to embryo environmental conditions can affect embryo growth. Changes in gene expression is one of the embryo responses to such conditions that may influence developmental potential and phenotype during later gestation. The signalling network Myc/Max/Mxd function as a molecular switch that regulates cell growth, proliferation and differentiation by controlling a common set of genes. RING finger protein 17(Rnf17) enhance Myc activity by sequestering all four members of Mxd family and creating a "Mxd-null phenotype". The MXD family functions as MYC repressor proteins. Two isoforms were described for Rnf17, long (Rnf17L) and short (Rnf17S). Rnf17 is expressed in adult mouse testis and in the mouse preimplantation embryo. The Rnf17 proteins contain RING finger domain and varying copies of the Tudor repeat domain (Tdrd). The aim of my thesis was to study the potential for Rnf17 regulating the Myc/Max/Mxd network during preimplantation development on the phenotype of the blastocyst and foetal testes. First, F9 murine carcinoma cells were used to question whether Rnf17 can modulate Myc responses. Functional assays were developed for Rnf17 over-expression by expression plasmids or Rnf17 knockdown by RNAi construct. The specificity of Rnf17 E3 ligase was investigated by co-transfection of Flagg-tagged constructs for RNF17 and MXD1 in F9 cells. Second, expression of Rnf17 mRNA and subcellular localisation of RNF17 protein were examined in mouse preimplantation embryo and in E17.5 foetal testes under normal condition and in response to maternal protein diets (LPD; 9% casein, HPD; 30% casein and control NPD; 18% casein). Finally Rnf17 knockdown was performed in mouse embryo by siRNA microinjection to point out the role of Rnf17 in embryo development.RNF17 was able to degrade MXD1 by ubiquitinylation pathway in co-transfected Cos-1 cells. Rnf17-SV40 expression construct significantly induced Luciferase activity of c-Myc reporter construct (P?0.05) when over-expressed in F9 cells, and knockdown of Rnf17 using Rnf17-RNAi construct significantly reduced Luciferase activity of Rnf17-sensor construct (P?0.05). Rnf17 mRNA is expressed through preimplantation development, in E17.5 foetal testes and in F9 cells. Members of Myc/Max/Mxd are expressed in mouse preimplantation embryo. The expression pattern of RNF17 in F9 cells and mouse embryos was predominantly nuclear and also presented in the cytoplasm. RNF17 was only expressed in the nuclei of Sertoli cells with faint signal in prospermatogonia in E17.5 foetal testes. Knockdown of Rnf17 in microinjected embryos using Rnf17_siRNA reduced expression of Rnf17S, delayed blastocyst formation, and reduced RNF17 protein signal. Maternal diet differentially regulate expression of Rnf17 and c-Myc in mouse blastocyst and E17.5 testes.In conclusion, over-expression of Rnf17 can amplify Myc response in F9 cells. MXD is a target protein for Rnf17 E3 ligase. Knockdown of Rnf17 in mouse embryo delayed blastocyst development. This study implicates that Rnf17 involved in regulating Myc/Max/Mxd signalling network and indicates a role for Rnf17 in blastocyst proliferation and growth. Changes in Rnf17 expression have the capacity to modulate early embryonic development and may contribute to phenotypic changes occurring later in life
