Towards a determination of the chiral couplings at NLO in 1/N(C): L_8(mu) and C_38(mu)
We present a dispersive method which allows to investigate the low-energy
couplings of chiral perturbation theory at the next-to-leading order (NLO) in
the 1/N(C) expansion, keeping full control of their renormalization scale
dependence. Using the resonance chiral theory Lagrangian, we perform a NLO
calculation of the scalar and pseudoscalar two-point functions, within the
single-resonance approximation. Imposing the correct QCD short-distance
constraints, one determines their difference Pi(t)=Pi_S(t)-Pi_P(t) in terms of
the pion decay constant and resonance masses. Its low momentum expansion fixes
then the low-energy chiral couplings L_8 and C_38. At mu_0=0.77 GeV, we obtain
L_8(mu_0)^{SU(3)} = (0.6+-0.4)10^{-3} and C_{38}(mu_0)^{SU(3)}=(2+-6)10^{-6}.Comment: Extended version published at JHEP01(2007)039. A NLO prediction for
the O(p6) chiral coupling C_38 has been added. The original L_8 results
remain unchange
Collapsing Burrow Causes Death of a Eurasian Beaver, Castor fiber
The death of a Eurasian Beaver Castor fiber caused by a collapsing burrow in southeast Norway is reported. Two days of heavy rainfall had presumably caused the burrow to collapse, suffocating the animal
Metastatic non-small-cell lung cancer: consensus on pathology and molecular tests, first-line, second-line, and third-line therapy: 1st ESMO Consensus Conference in Lung Cancer; Lugano 2010
The 1st ESMO Consensus Conference on lung cancer was held in Lugano, Switzerland on 21 and 22 May 2010 with the participation of a multidisciplinary panel of leading professionals in pathology and molecular diagnostics, medical oncology, surgical oncology and radiation oncology. Before the conference, the expert panel prepared clinically relevant questions concerning five areas: early and locally advanced non-small-cell lung cancer (NSCLC), first-line metastatic NSCLC, second-/third-line NSCLC, NSCLC pathology and molecular testing, and small-cell lung cancer to be addressed through discussion at the Consensus Conference. All relevant scientific literature for each question was reviewed in advance. During the Consensus Conference, the panel developed recommendations for each specific question. The consensus agreement on three of these areas: NSCLC pathology and molecular testing, the treatment of first-line, and second-line/third-line therapy in metastatic NSCLC are reported in this article. The recommendations detailed here are based on an expert consensus after careful review of published data. All participants have approved this final updat
Evaluación cualitativa del programa comunitario Irunsasoi para la promoción de la actividad física: la perspectiva de los médicos
Objectives: The sedentarism is an important conditioner of morbidity and mortality. The communitarian programs of promotion of physical activity that include a pursuit protocol can help and complement to the medical advice in the consultation. The objectives that we marked ourselves with this study have been to know the opinion the doctors on the prescription of physical activity and the implantation of the Irunsasoi program, collaboration between the doctors of Primary Attention and the technicians of physical activity of the council of Irún City to help the sedentary people. Methodology Design: Technique of focal groups. The discussions were recorded and later transcribed, previous authorization, for their analysis. Location: Primary attention. Irún Centro health Center. Subjects: The study population was the 15 doctors of AP. Two groups of 5 doctors, homogenous were made in age and sex, the recruitment was made, the invitation at random to participate was verbal by the investigator without no refusal took place. Measures: The discussion lines were grouped in: attitude before the advice and participation in the program, difficulties of collaboration and proposals of improvement. Results: Positive evaluation of the program to have enabled personnel, sufficient time and guarantees of pursuit. The collaboration difficulties are based on the forgetfulness not to have it built-in to our mechanics of work and to wort in other activities by lack of time. Conclusions: He is positive to work jointly with the technicians of physical activity. Aspects to improve: the formation in prescription of physical activity, the implication of nurses, the circuit of communication and the support in computerized historyObjetivos: El sedentarismo es un importante condicionante de morbilidad y mortalidad. Los programas comunitarios de promoción de actividad física que incluyan un protocolo de seguimiento pueden ayudar y complementar al consejo médico en la consulta. Los objetivos que nos marcamos con este estudio han sido conocer la opinión de los médicos sobre la prescripción de actividad física y sobre la implantación del programa Irunsasoi, de colaboración entre los médicos de Atención Primaria y los técnicos de actividad física del Ayuntamiento de Irún para ayudar a las personas sedentarias. Metodología: Diseño: Técnica de grupos focales. Las discusiones fueron grabadas y posteriormente transcritas, previa autorización, para su análisis. Emplazamiento: Atención primaria. Centro de salud Irún Centro. Sujetos: La población de estudio fueron los 15 médicos de AP. Se realizaron dos grupos de 5 médicos, homogéneos en edad y sexo, el reclutamiento se realizó al azar, la invitación a participar fue verbal por el investigador sin que se produjera ninguna negativa. Medidas: Los ejes de discusión se agruparon en: actitud ante el consejo y participación en el programa, dificultades de colaboración y propuestas de mejora. Resultados: Valoración positiva del programa por disponer de personal capacitado, tiempo suficiente y garantías de seguimiento. Las dificultades de colaboración se basan en el olvido por no tenerlo incorporado a nuestra mecánica de trabajo y priorización de otras actividades por falta de tiempo. Conclusiones: Es positivo trabajar conjuntamente con los técnicos de actividad física. Aspectos a mejorar: la formación en prescripción de actividad física, la implicación de enfermería, el circuito de comunicación y el soporte en la historia informatizad
Viability of Strongly-Coupled Scenarios with a Light Higgs-like Boson
We present a one-loop calculation of the oblique S and T parameters within strongly coupled models of electroweak symmetry breaking with a light Higgs-like boson. We use a general effective Lagrangian, implementing the chiral symmetry breaking SU(2)(L) circle times SU(2)(R) -> SU(2)(L+R) with Goldstone bosons, gauge bosons, the Higgs-like scalar, and one multiplet of vector and axial-vector massive resonance states. Using a dispersive representation and imposing a proper ultraviolet behavior, we obtain S and T at the next-to-leading order in terms of a few resonance parameters. The experimentally allowed range forces the vector and axial-vector states to be heavy, with masses above the TeV scale, and suggests that the Higgs-like scalar should have a WW coupling close to the standard model one. Our conclusions are generic and apply to more specific scenarios such as the minimal SO(5)/SO(4) composite Higgs model
Acorn flour and sourdough: an innovative combination to improve gluten free bread characteristics
Nowadays, challenges in gluten free breads (GFB) are focused on improving the nutritional and health benefits. Acorn flour is
an underexploited sustainable ingredient, naturally gluten free, with many nutritional and technological advantages. The aim
of this study was to explore the interaction of acorn flour supplementation (up to 35%) to rice flour and sourdough process
to obtain rice based GFB. Different levels of rice flour replacement with acorn flour (0%, 23% and 35%), and sourdough
(20%) were tested in a basic GFB recipe, and technological, nutritional, and functional GFB characteristics evaluated. The
combination of acorn flour and sourdough was responsible for acidifying dough and bread. Breads containing 35:65 acorn
flour: rice flour led to harder breads with lower crumb luminosity and with reddish and brownish tones, besides improved
structural features when adding sourdough. That combination of sourdough and acorn flour reduced the rate and the extent
of starch hydrolysis, as well as increase the minerals content, total phenolic compounds and antioxidant activity. Therefore,
the combination of acorn flour and sourdough process allows obtaining rice based GFB with better nutritional patterninfo:eu-repo/semantics/publishedVersio
