Abstract Fe‐based soft magnetic wire with transverse magnetic anisotropy was obtained by stress current annealing. Its circular permeability, µ = µ′ – jµ″, has been determined from the measurements of impedance, Z = R + jωL, as a function of frequency (f = 10 – 105 Hz), AC current amplitude (I = 0.1 – 100 mA) and DC b…
\n Neste trabalho nós produzimos e caracterizamos superfícies de diamante policristalino com áreas seletivas oxidadas e fluoradas a partir de superfícies originalmente hidrogenadas, usando um canhão de plasma para bombardear a superfície do diamante. A técnica que foi utilizada para a produção de filmes de diamante co…
Electro-optical properties of deformed helix ferroelectric liquid crystal\n(DHFLC) cells are studied by using a general theoretical approach to\npolarization gratings in which the transmission and reflection matrices of\ndiffraction orders are explicitly related to the evolution operator of\nequations for the Floquet…
Chronic inflammation is a major pathological basis for tumor development and two examples are H. pylori infection of the stomach mucosa and inflammatory bowel disease, which are strongly associated with gastric and colon adenocarcinoma, respectively. In this thesis we investigated H. pylori-induced chronic gastritis a…
I desire to express my deepest gratitude to my special friend, Sónia.She is the friend for all moments, with whom I shared ideas, opinions, victories, but also my concerns and disappointments.And when I have most needed, she was always there for encouraging and supporting.Thanks for being around!I would like to thank…
We propose an efficient plasmonic structure consisting of metal strips and thin-film silicon for solar energy absorption. We numerically demonstrate the absorption enhancement in symmetrical structure based on the mode coupling between the localized plasmonic mode in Ag strip pair and the excited waveguide mode in sil…
The adsorption of biologically active molecules, such as the DNA bases, amino acids, on solid surfaces has been the subject of a number of experimental and theoretical studies in the past years. The understanding of the self-assembly mechanism of bioactive molecules on surfaces not only is fundamentally important in t…
Les chromenes photochromiques sont largement utilises dans les technologies modernes en raison de leur capacite a changer les proprietes sous irradiation UV. Les chromenes presentes dans ce travail possedent en outre des fragments pouvant participer a la coordination avec des cations metalliques, acides amines, ou de…
L’etude presentee est consacree a l’usinabilite de la fonte a graphite vermiculaire. Celle-ci se situe entre la fonte a graphite lamellaire et la fonte a graphite spheroidale par rapport a la forme du graphite constituant ce materiau. Elle est utilisee depuis plus de cinq ans dans les blocs moteurs diesel afin d’ameli…
We report a systematic study on the influence of antiferromagnetic and ferromagnetic phases of Eu^2+ moments on the superconducting phase upon doping the As site by isovalent P, which acts as chemical pressure on EuFe_2As_2. Bulk superconductivity with transition temperatures of 22 K and 28 K are observed for x=0.16 a…
Abstract Abstract 1766 Introduction: A combination of Rituximab with a chemotherapy regimen consisting of cyclophosphamide, vincristine, doxorubicin, and prednisone (R-CHOP) is the current standard treatment for diffuse large B-cell lymphoma (DLBCL). Doxorubicin is known to induce short-time and long-time cardiac toxi…
In the mononuclear title complex, [Mn(NCS)(2)(C(11)H(11)N(3)O)(4)], the Mn(II) atom, lying on an inversion center, is coordinated by two monodentate thio-cyanate anions and four monodentate 1-phenyl-3-(1H-1,2,4-triazol-1-yl)propan-1-one ligands in a distorted octa-hedral geometry. Each complex mol-ecule is linked to f…
Das maximale Trubaufnahmevermögen eines Filterkuchens ist ein wichtiges Kriterium für die Vorhersagbarkeit der Standzeit des Filters. In Praxisfiltrationen in Brauereien konnte nachgewiesen werden, dass sich die Filtration mit Zellulose als Filterhilfsmittel grundsätzlich in zwei Bereiche unterteilen lässt. Zunächst v…
Käesolev väitekiri koosneb sissejuhatusest, neljast peatükist, kirjanduse loetelust ja kokkuvõttest. \n Väitekiri on pühendatud tükiti konstantse paksusega silindriliste koorikute võnkumiste uurimisele juhul, kui koorikus on praod. Praod eeldatakse olevat stabiilsed konstantse sügavusega ringikujulised praod, mis asuv…
Extended π-conjugation in molecular systems is being extensively exploited in a rapidly expanding range of electronic and photonic applications. The modification of such extended systems through the use of heteroatoms allows their tailoring to specific requirements. In particular, the use of the vacant boron p(π) orbi…
On 8th August this year, I posted on a fascinating article that had just appeared in Science[1] in which the crystal structure was reported of two small molecules, 1,3-dimethyl cyclobutadiene and carbon dioxide, entrapped together inside a calixarene cavity.
In the title compound, [ZnI(2)(C(24)H(16)N(6))], the Zn(II) ion is five-coordinated in a distorted trigonal-bipyramidal geometry by an N,N,N-tridentate 2,3,5,6-tetra-2-pyridinylpyrazine ligand and two iodide ions. The I(-) ions both occupy equatorial sites. Within the ligand, the dihedral angles between the central py…
Le Zirconium, sous forme d’alliage, est l’element principal du gainage combustible des reacteurs nucleaires a eau pressurisee. Sous irradiation, les gaines s’allongent de maniere significative, phenomene attribue a la croissance de boucles de dislocations lacunaires dans les plans de base de la structure hexagonale co…
In dieser Arbeit wird die partielle Autoxidation von Cyclohexan zu Cyclohexanol und Cyclohexanon mit Luftsauerstoff in einem Kapillarrohrreaktor untersucht. Gegenüber dem konventionellen Verfahren wurde die Temperatur auf 180-250°C und der Druck auf 20-80 bar angehoben. Auf diese Weise konnte eine Steigerung der Raum-…
Abstract Abstract 2156 Background: Acute myeloid leukemia (AML) at initial diagnosis or relapse may present with extramedullary (EM) AML. Data on the prevalence of EM AML at diagnosis are scarce and rely mostly on retrospective, clinical analyses. However, previous studies attributed EM AML as an impacting prognostic…
