On the equivariant Tamagawa number conjecture for abelian extensions of a quadratic imaginary field

Let k be a quadratic imaginary field, p a prime which splits in k/Q and does not divide the class number hk of k. Let L denote a finite abelian extention of k and let K be a subextention of L/k. In this article we prove the p-part of the Equivariant Tamagawa Number Conjecture for the pair (h0(Spec(L)),Z[Gal(L/K)]).

The Parity of the Number of Irreducible Factors for Some Pentanomials

It is well known that Stickelberger-Swan theorem is very important for determining reducibility of polynomials over a binary field. Using this theorem it was determined the parity of the number of irreducible factors for some kinds of polynomials over a binary field, for instance, trinomials, tetranomials, self-reciprocal polynomials and so on. We discuss this problem for type II pentanomials namely x^m +x^{n+2} +x^{n+1} +x^n +1 \in\ IF_2 [x]. Such pentanomials can be used for efficient implementing multiplication in finite fields of characteristic two. Based on the computation of discriminant of these pentanomials with integer coefficients, it will be characterized the parity of the number of irreducible factors over IF_2 and be established the necessary conditions for the existence of this kind of irreducible pentanomials.

Parity of the Number of Irreducible Factors for Composite Polynomials

Various results on parity of the number of irreducible factors of given polynomials over finite fields have been obtained in the recent literature. Those are mainly based on Swan’s theorem in which discriminants of polynomials over a finite field or the integral ring Z play an important role. In this paper we consider discriminants of the composition of some polynomials over finite fields. The relation between the discriminants of composed polynomial and the original ones will be established. We apply this to obtain some results concerning the parity of the number of irreducible factors for several special polynomials over finite fields.

Influence of occupation number of single particle levels on K - K charge transfer in collisions of 90 keV - Ne{^9+} on Ne

The influence of the occupation of the single particle levels on the impact parameter dependent K - K charge transfer occuring in collisions of 90 keV Ne{^9+} on Ne was studied using coupled channel calculations. The energy eigenvalues and matrixelements for the single particle levels were taken from ab initio self consistent MO-LCAO-DIRAC-FOCK-SLATER calculations with occupation numbers corresponding to the single particle amplitudes given by the coupled channel calculations.

Algorithms for Tamagawa Number Conjectures

In dieser Arbeit werden Algorithmen zur Untersuchung der äquivarianten Tamagawazahlvermutung von Burns und Flach entwickelt. Zunächst werden Algorithmen angegeben mit denen die lokale Fundamentalklasse, die globale Fundamentalklasse und Tates kanonische Klasse berechnet werden können. Dies ermöglicht unter anderem Berechnungen in Brauergruppen von Zahlkörpererweiterungen. Anschließend werden diese Algorithmen auf die Tamagawazahlvermutung angewendet. Die Epsilonkonstantenvermutung kann dadurch für alle Galoiserweiterungen L|K bewiesen werden, bei denen L in einer Galoiserweiterung E|Q vom Grad kleiner gleich 15 eingebettet werden kann. Für die Tamagawazahlvermutung an der Stelle 1 wird ein Algorithmus angegeben, der die Vermutung für ein gegebenes Fallbeispiel L|Q numerischen verifizieren kann. Im Spezialfall, dass alle Charaktere rational oder abelsch sind, kann dieser Algorithmus die Vermutung für L|Q sogar beweisen.

Study of individual lactation patterns of Iranian dairy buffaloes

The aims of the current study were 1) to investigate the effects of some environmental factors on lactation curve traits (LCTs) including initial milk yield (A), peak yield (PY), days to attain peak yield (PD), inclining- and declining slope of lactation (B and C, respectively), persistency (Per), and 240-d milk yield, and 2) to estimate pairwise phenotypic correlations between these traits in two Iranian buffalo ecotypes (Khuzestani and Azeri buffaloes). The dataset consisted of 15396 and 9283 lactations from 6632 Khuzestani and 3558 Azeri buffaloes, respectively (collected during 1992–2009). The results revealed that almost all of the factors had significant effects on the majority of the LCTs, whereby age group, parity and season of calving had greater influence on 240-d milk yield and PY than the other LCTs in both of the ecotypes. These effects were more apparent in Khuzestani buffaloes than in Azeri buffaloes. In the Khuzestani ecotype, the LCTs were significantly correlated with each other. However, in the Azeri ecotype the 240-d milk yield showed no significant relationship with parameters B, PD and Per. In conclusion, the studied factors play an important role in determining both the shape of the lactation curve and the overal performance of Iranian dairy buffaloes.

Seguridad de los antipsicoticos en embarazo en pacientes con psicosis. Revisión sistemática

Enfermedades mentales de tipo psicótico en gestantes se han asociado con mayor número de resultados negativos. Los síntomas psicóticos durante el embarazo se presentan aproximadamente 7.1 por 100.000 casos. Dentro de las consecuencias se incluye mayor riesgo de parto pretérmino, bajo peso al nacer, alteraciones placentarias, malformaciones congénitas de predominio cardiovascular y mayor tasa de muertes perinatales. Como abordaje terapéutico son frecuentes los antipsicóticos de primera generación, aceptados como seguros pero en menor grado se han considerados los antipsicóticos de segunda generación pues ha sido escasamente evaluada su seguridad durante la gestación. Aún existe controversia sobre los potenciales efectos secundarios de algunos antipsicóticos dado los resultados contradictorios. Métodos: Revisión sistemática de la literatura de artículos que proporcionaron mejor evidencia para determinar cuáles antipsicóticos de elección durante la gestación en pacientes con esquizofrenia de acuerdo a su perfil de seguridad. Se evaluó calidad metodológica reconociendo particularidades y resultados de los estudios incluidos. Resultados: De 39 estudios seleccionados, cinco fueron incluidos en esta revisión, clasificándose como nivel de evidencia IIa y evaluados según su calidad metodológica con escala NOS. Se evaluó paso placentario de antipsicóticos, malformaciones fetales, complicaciones obstétricas como parto pretérmino, bajo y alto peso fetal, complicaciones respiratorias, diabetes gestacional, aborto espontáneo, entre otros. Discusión: Se debe sopesar el riesgo-beneficio, la significancia estadística, la significancia clínica y las particularidades de las pacientes a tratar. Conclusión: Los estudios analizados evaluaron diferentes medicamentos antipsicóticos, dificultando consolidación de información en especial en conclusiones solidas ante algunas premisas como fármacos de elección.

How do I get the Chapter number in Table or Figure captions to restart in Appendices using the University thesis template in Word 2010?

If you have added the Chapter number to your Table or Figure captions they will show as 1.1, 1.2 and so on. This is linked to the numbering used in the Heading 1 style. However, once you get to the Appendices the last Chapter number will continue throughout the Appendices as the Appendix heading isn't Heading 1. So what you need to do is get Word to understand that the style from which it should be picking up the first part of the Caption has changed and that it will need to restart the numbering again in each subsequent Appendix. This isn't too complex but you must follow the instructions to the letter or else it won't work.

Brain Tumour, Mood Disorder and Encephalopathy. Discusion of the Clinical Case Presented in Volume 6, Number 2

We report a case of a 65 years old female patient, who was admitted to the hospital with non specific neurological symptoms and who had preliminary imagenological findings of an extra-axial tumor mass (a meningioma of the sphenoid’s wing), which was taken to complete surgical removal. Afterwards, she developed progressive neurologic deterioration until her death. The final diagnosis was acute spongiform encephalophaty, and was obtained by cerebral biopsy. Spongiform encephalopathy was described, almost a century ago, as the Creutzfeldt-Jakob Disease, poorly diagnosed in our environment because of its low frequency and uncommon onset, which starts with a mood disorder followed by a phase of dementia and a final fatal outcome. The gold standard for the diagnosis is based on a biopsy or an autopsy of the brain, with immunohistochemical stains for the prionic abnormal protein.
